Technical Field

The invention belongs to the field of valves, and particularly relates to a faucet, in particular to an electric heating faucet, in particular to an instant heating type electric heating faucet.

Background

The valve is one of the most common control devices in production life, and is used for controlling the fluid passing state, such as controlling the type of fluid passing through and controlling the flow rate of the fluid passing through. The most commonly known and accessible faucet is used in daily life. The water tap can be divided into a screw type, a wrench type, a lifting type, an induction type and the like according to the opening mode. The spiral handle is turned on by screwing, and when the spiral handle is turned on, the spiral handle needs to be rotated for many circles, the water outlet flow is adjusted by the number of turns of screwing, and the flow is larger when the number of turns of screwing is larger; the wrench type handle is opened through horizontal rotation, the water outlet flow is controlled by the opening angle, the larger the opening angle is, the larger the flow is, and the maximum angle is usually 90 degrees; the lifting handle is opened by vertically lifting, and the water outlet flow is controlled by the opening angle, wherein the larger the opening angle is, the larger the flow is, and the maximum angle is usually less than 45 degrees; the induction type faucet can automatically discharge water by induction as long as a handle extends to the lower part of the faucet, but the water discharge flow is usually fixed and cannot be adjusted. The water tap can be divided into single cold tap, single handle double valve core tap and double handle double valve core tap according to water using mode. The cold only faucet has only one fluid outlet port and one fluid inlet port. The single handle dual spool faucet has a fluid outlet end, and a first fluid inlet end that is a cold fluid inlet end and a second fluid inlet end that is a hot fluid inlet end. The double-handle double-valve-core water faucet comprises a cold water faucet and a hot water faucet which are respectively independent, wherein the cold water faucet and the hot water faucet are respectively provided with a control handle and comprise a cold water control handle, a hot water control handle, a cold water valve core and a hot water valve core, and the double-handle double-valve-core water faucet is provided with a fluid outlet end, a first fluid inlet end of the cold fluid inlet end and a second fluid inlet end of the hot fluid inlet end.

The single-handle duplex valve core is the most common valve core of the water faucet in life and production, in particular to a ceramic wafer single-handle duplex valve core which is a cold and hot water faucet valve core commonly used in kitchens and toilets at present. The case includes the gasket that stationary blade and moving plate constitute, operating device mainly is the sealed gliding control handle of control moving plate relative stationary blade, be equipped with cold inlet opening (cold fluid entry end) on the stationary blade, hot inlet opening (hot-fluid entry end) and apopore (fluid exit end), be equipped with the passageway on the moving plate, this passageway is used for communicateing hot inlet opening and apopore when the moving plate is sealed to slide relative stationary blade, perhaps cold inlet opening and apopore, perhaps hot inlet opening, cold inlet opening and apopore. Taking a lift-type single-handle duplex valve core as an example, the common operation standard in China is that the area of the control handle which is turned left to the position near the limit position is the water outlet hole which only outputs hot water, and at the moment, the water outlet hole is only communicated with the hot water inlet hole through a channel; when the control handle is turned right to the area near the limit position, only cold water is discharged from the water outlet hole, and at the moment, the water outlet hole is only communicated with the cold water inlet hole through a channel; a water mixing area for mixing cold water and hot water is arranged between the cold water inlet area and the hot water inlet area, the water outlet hole is communicated with the cold water inlet hole and the hot water inlet hole through a channel, the control handle rotates leftwards, the hot water ratio in the cold water inlet ratio and the hot water inlet ratio is larger, and the water is hotter until the water is changed into pure hot water; the more the control handle rotates rightwards, the larger the proportion of cold water in the proportion of cold water and hot water inlet is, the colder the water is until the water becomes pure cold water. And in the left-right rotation of the control handle, the water outlet flow at the moment is adjusted through the uplifting angle of the uplifting control handle, and the larger the angle is, the larger the flow is.

Regardless of the difference between the various mixing valve cartridges or the dual hot and cold valve cartridges, the cold water inlet of the existing mixing valve cartridge or dual hot and cold valve cartridge of the faucet is usually directly connected to cold water (or normal temperature water, which refers to water in a natural state without additional heating, and does not refer to water at a normal temperature, such as 25 ℃), such as tap water, and the hot water inlet is connected to various hot fluid supply devices for providing hot fluid (such as hot water). For controlling the flow of the hot fluid through the valve, it is common to control the flow of the hot water by correspondingly providing a hot fluid supply device for providing the hot fluid (e.g., hot water), a hot fluid outlet of the hot fluid supply device is communicated with a hot fluid inlet of the valve device, and the common hot fluid supply devices in daily life are various water heaters, such as gas water heaters, natural gas water heaters, electric water heaters, solar water heaters, air energy water heaters, and the like.

However, the existing water faucet has the following problems:

in the common faucet, the temperature is higher in summer, the cold water outlet temperature of the faucet is higher, and the user feels comfortable when directly putting cold water. Similarly, when the water is directly heated, since there is usually a distance from the water heater to the faucet, the water discharged from the faucet is always cold until the cold water in the distance is discharged, but the cold water is comfortable.

However, in autumn or spring, particularly in winter, the temperature is low, the cold water outlet temperature of the faucet is also low, the water body is uncomfortable to directly cool at the moment, and even the cold stabbing bone cannot be tolerated. Similarly, the hot water is directly released, as is the previous section of cold water. Moreover, when the hot water is used up, the hot water reserved in the pipeline and the water tank of the water heater cannot be utilized after the valve is closed, and the heat is wasted. Meanwhile, the hot water reserved in the water tank of the water heater can also cause the water tank scale to be rapidly generated, so that the service life of the water heater is prolonged, and the heating efficiency is reduced. Therefore, if hot water is used only for a short time, such as only washing one hand, washing one fruit, etc., the use of water heaters in the prior art wastes both time and water and energy and also affects the life of the water heater.

Compared with the common water faucet, the prior electric heating water faucet has the following advantages: although the water heater and the electric heating faucet have the advantages and disadvantages of each other in the above characteristics, the existing electric heating faucet only has one water inlet pipe connected with cold water, and cannot be used by connecting the water heater and the electric heating faucet, so that the advantages and the disadvantages are complemented. In another design scheme of the electric heating faucet, a water mixing valve core is adopted, the water mixing valve core is respectively provided with a cold water inlet and a hot water inlet, a water heater and the electric heating faucet can be connected for use, but an electric heating device is only arranged at the hot water inlet or the upstream of the hot water inlet, namely, only cold water in the front section of the hot water inlet water heater is heated, although the advantages and the disadvantages of the electric heating faucet are complemented, when a user only needs a small amount of hot water, the heating function of the electric heating faucet can be started and hot water is discharged, and meanwhile, the water heater enters a heating state or the hot water enters a hot water pipeline and is not utilized, so that the invalid starting of the water heater.

The applicant previously applied Chinese patent 'an electric heating faucet' (patent number 2018204432667), which has two water inlet pipes respectively connected with a cold water inlet pipe and a hot water inlet pipe to realize the combined use of a water heater and the electric heating faucet, and because an electric heating device is arranged in the faucet and can instantly heat cold water entering from the cold water inlet pipe, the actual water consumption requirement that a user only needs a small amount of hot water is effectively solved. However, since the electric heating faucet of the application is to place the control device and the heating device in the faucet, the following problems are difficult to solve: firstly, the contradiction between the heating power and the appearance volume, the heating power is large, the occupied space is large, and the appearance volume is increased, so that the application range is limited and the appearance is not attractive; secondly, the contradiction between the daily water environment and the electricity utilization safety measures exists, and the special water environment of the water faucet forces the electric heating component and the control circuit thereof in the electric heating water faucet to take more effective electricity utilization safety measures; and thirdly, the contradiction between the normal service life and the safe service life is caused, the normal service life of the common water faucet is longer, and the safe service life of the control device and the heating device is shorter and is limited by the mandatory industry. In contrast, the fluid heating apparatus according to the present application effectively solves the above problems by separating the valve device (e.g., a general faucet) from the control device and the heating device, so that the valve device is separated from the control device and the heating device, but how to transmit information between the general faucet (without an electrical signal output) and the control device and the heating device is achieved by the application, because the valve device is separated from the control device and the heating device, especially a general faucet is often used as the valve device in daily life.

Disclosure of Invention

The present application is a prior chinese patent application requiring the applicant: in the later application with application number 2019111093905, application number 2019-11-13, the content of the application is simplified to avoid repeated description, but it is to be stated that all the content of the earlier application is also the content recorded in the application.

One of the objects of the present invention is: the utility model provides a fluid heating device, realize passing information between ordinary valve device (do not have the signal output) and controlling means and heating device, especially can utilize the operating device of current valve to realize realizing the operation valve (for example switch valve, regulation flow or regulation fluid type etc.) simultaneously realizing wanting to heat and wanting not the freedom and swiftly control of heating and wanting not to heat, especially often adopt ordinary tap as the valve device in daily life, how to realize passing information between ordinary tap (do not have the signal output) and controlling means and heating device and realize controlling promptly the problem that this application will solve.

The second purpose of the invention is: the heating method of fluid heating device is provided, which can realize information transmission between the common valve device (without electric signal output) and the control device and the heating device, especially can realize free and rapid control of heating and not heating at the same time of operating the valve (such as opening and closing the valve, adjusting the flow or adjusting the fluid state, etc.) by using the operating mechanism of the existing valve, especially in daily life, the common faucet is often adopted as the valve device, and how to realize information transmission between the common faucet (without electric signal output) and the control device and the heating device to realize control is the problem to be solved by the application.

The purpose of the invention is realized by the following technical scheme:

a fluid heating device comprises a valve device and a heating device, wherein the valve device is provided with a fluid outlet end and at least one fluid inlet end, the first fluid inlet end of the valve device is a cold fluid inlet end (namely the first fluid inlet end of the valve device in the prior art is not communicated with a hot water outlet end of a hot fluid supply device, but is directly communicated with cold fluid), the fluid heating device also comprises a control device, the control device is provided with at least one fluid inlet end and at least one fluid outlet end, the first fluid outlet end of the control device is communicated with the fluid inlet end of the heating device, and the fluid outlet end of the heating device is communicated with the first fluid inlet end of the valve device (in a connection mode, the first fluid inlet end of the control device is a cold fluid inlet end, and the first fluid outlet end of the control device is a cold fluid outlet end, namely the first fluid inlet end of the control device is not communicated, or the fluid outlet end of the heating device is communicated with the first fluid inlet end of the control device (in this connection mode, the fluid inlet end of the heating device is a cold fluid inlet end, that is, the fluid inlet end of the heating device is not communicated with the hot water outlet end of the hot fluid supply device), the first fluid outlet end of the control device is communicated with the first fluid inlet end of the valve device, and the operation of the operating mechanism of the valve device triggers the control device to control the heating device.

In the invention, by arranging the heating device at the upstream of the cold fluid inlet end of the valve device, the operation of the operating mechanism of the valve device triggers the control device to control the heating device (for example, controlling whether the heating device is heated or not, even further heating power and heating time and the like), thereby realizing free and quick control that heating is needed and heating is not needed while the valve is operated (for example, the valve is switched on and off, flow is regulated or fluid type is regulated and the like) by utilizing the operating mechanism of the existing valve, and obtaining cold fluid/cold water or hot fluid/hot water by freely and quickly operating the operating mechanism of the valve device. Specifically, the operating mechanism of the valve device controls the flow change at the first fluid inlet end, the flow at the first fluid inlet end of the control device changes along with the flow change, and the control device senses the flow change at the first fluid inlet end and correspondingly controls the heating device according to the flow change. For example, an operation A of the operating mechanism of the valve device triggers the control device to control the heating device to heat, an operation B of the operating mechanism of the valve device triggers the control device to control the heating device not to heat, an operation C of the operating mechanism of the valve device triggers the control device to control the heating device to increase the heating power, an operation C' of the operating mechanism of the valve device triggers the control device to control the heating device to decrease the heating power, and so on. The valve device generally includes a control handle as an operating mechanism, and a valve core controlled by the control handle, and the passing condition of fluid through the valve core, such as valve on-off, flow rate and the like, is adjusted by operating the control handle. A heating device is a device for heating a fluid flowing through the device, in particular through the device from the inside thereof. The valve device and the heating device have various structures and forms in the prior art, and can be used in the invention as long as the valve device and the heating device are applicable to the scheme of the invention. The operating mechanism of the valve device comprises a conventional operating mechanism, such as a control handle of a faucet, but since the flow rate of the first fluid inlet port is also varied by operating the components of the faucet, such as the spout, the bubbler and the flow restrictor, at the outlet of the faucet, the operating mechanism of the valve device also comprises the components of the faucet, such as the spout, the bubbler and the flow restrictor, at the outlet of the faucet. That is, the operation mechanism of the valve device controls the flow change of the first fluid inlet end, and also includes components such as a water outlet nozzle, a bubbler and a flow restrictor at the water outlet of the valve device such as a faucet, and the flow change of the first fluid inlet end is controlled by adjusting or switching the components.

The solution according to the invention can therefore also be applied to single-cold taps of the prior art (having only one fluid outlet and one fluid inlet), so that such taps can also obtain cold/cold or hot fluid/hot water at will.

The scheme of the invention can also be suitable for a pull-out cold and hot water faucet, and the pull-out pipe is arranged on the pull-out cold and hot water faucet, so that the scheme of the invention is not only suitable for the pull-out cold and hot water faucet in the prior art, but also suitable for a novel pull-out cold and hot water faucet, and the specific reference is made to the embodiments of the invention, such as embodiments 1, 12 and 13. In embodiments 1 and 12, the same connection method is adopted for the pull-out type hot and cold water faucet (the common pull-out type hot and cold water faucet) in the prior art, and in embodiment 13, the same connection method is adopted for the novel pull-out type hot and cold water faucet (the sectional pull-out type hot and cold water faucet). The common drawing type cold and hot water faucet is provided with a drawing pipe which can be drawn out or retracted from the water outlet end of the faucet (usually, a falling body which can slide on the outer surface of the drawing pipe is also sleeved on the drawing pipe, and gravity provided by the falling body is utilized to assist the drawing pipe to smoothly retract after being drawn out), one end of the drawing pipe is communicated with a valve core of the faucet, and the other end of the drawing pipe is communicated with the water outlet end of the faucet; the novel drawing type cold and hot water faucet (the sectional drawing type cold and hot water faucet) is characterized in that a drawing pipe of the novel drawing type cold and hot water faucet (the sectional drawing type cold and hot water faucet) is divided into a front section drawing pipe and a rear section drawing pipe, the front section drawing pipe leads to a faucet valve core, the rear section drawing pipe leads to a faucet water outlet end (generally, a falling body is sleeved on the rear section drawing pipe, gravity provided by the falling body is utilized to assist the rear section drawing pipe to smoothly retract after being pulled out, the front section drawing pipe is only used for connection, in addition, if a falling body is not sleeved on the rear section drawing pipe, the novel drawing type cold and hot water faucet (the sectional drawing type cold and hot water faucet) can be a novel cold and hot water faucet (the sectional drawing type cold and hot water faucet), and the novel drawing type. In cooperation with a specific mode in the application, when the sectional drawing type cold and hot water faucet (including the sectional cold and hot water faucet) starts cold water in a cold water pipe, whether heating is carried out or not can be controlled at will through different condition control so as to directly obtain cold fluid/cold water or heated hot fluid/hot water; when the hot water in the hot water pipe is started, whether the hot water is heated or not can be controlled in a careful manner so as to supplement the heat to the front section cold water in the hot water pipe and further reheat the hot water in the hot water pipe; reheating may or may not be performed with care when the mixing water is turned on.

Meanwhile, the heating device is arranged at the upstream of the cold fluid inlet end of the valve device, so that the valve device is not influenced to be further externally connected with an existing hot fluid supply device (at the moment, the valve device is also provided with a second fluid inlet end which is a hot fluid inlet end connected with the hot fluid supply device, or the valve device comprises a cold fluid/cold water valve and a hot fluid/hot water valve which are respectively independent), for example, various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, an air energy water heater and the like. At this time, the scheme of the invention can be switched to obtain cold fluid/cold water or hot fluid/hot water or warm fluid/warm water at will.

The first fluid and the second fluid can be the same kind of fluid, or different kinds of fluids, such as water and other fluids, or both water, and the like; meanwhile, the fluid may be the same type of fluid in different states, or the same type of fluid in the same state, such as cold water and hot water, or both cold water and hot water. The cold/cold or hot/warm or warm/warm fluids are only a relative concept and not an absolute meaning, i.e. cold/cold fluid means only a lower temperature relative to hot/warm fluid, warm/warm fluid means only a higher temperature relative to cold/cold water, hot/warm fluid means only a higher temperature relative to warm/warm fluid; also, in general, cold fluid/cold water refers to normal temperature fluid/water, and refers to fluid/water in a natural state without additional heating, such as tap water, but does not refer to fluid/water at normal temperature, such as 25 ℃. Likewise, first and second (e.g., first fluid inlet end and second fluid inlet end) are merely meant to distinguish between the two references, and do not indicate conceptual differences in order or location.

Alternatively 1, the control device has mode shifts including one or more of a winter mode, a summer mode, a four season a mode, and a four season B mode. In the scheme, a plurality of modes are arranged to be matched with other specific schemes of the invention, so that a plurality of predefined automatic processes can be realized, and the user can obtain the use experience most suitable for the modes/seasons under different modes/seasons. The winter mode, the summer mode, the four-season A mode and the four-season B mode do not have literal absolute meanings, and are named only for distinguishing the modes; the references to winter, summer, and four season a/B are merely for convenience of user/consumer understanding of the distinction, e.g., winter mode is generally suitable for use in winter, summer mode is generally suitable for use in summer, but does not mean that winter mode is not suitable for use in summer, or that summer mode is not suitable for use in winter. The control device can have one of two or three mode gears, and if the multi-mode gears can be switched by means of a mode selector switch, the mode selector switch is not provided if only one mode gear is provided.

As a further option 2 of option 1, the control device further comprises a flow monitoring component, the mode shift is switched to the winter mode, and the control device controls the heating device to heat when conditions 1 and 9 are met, and controls the heating device not to heat when conditions 1 or 9 are not met; wherein the condition 1 is that the flow monitoring part monitors that the current flow rate at the first fluid inlet end of the control device is equal to or greater than L1, and the condition 9 is that the flow monitoring part does not monitor that the flow rate at the first fluid inlet end of the control device undergoes a continuous change from equal to or greater than L1 to less than L1 within the time T2, and then the current flow rate is equal to or greater than L1; or condition 9 is that the flow monitoring component does not monitor that the flow at the first fluid inlet end of the control device has undergone a continuous process of flow from less than L1 to equal to or greater than L1 to less than L1 for time T2 (i.e., turn down-turn up or turn up-turn down-turn up, and in extreme cases, off-on or on-off-on) and then the current flow is equal to or greater than L1. In this embodiment, the operating mechanism of the valve device is operated to open the first fluid inlet port of the valve device and adjust the flow rate to be equal to or greater than L1 so that the flow rate at the first fluid inlet port is equal to or greater than L1, and the flow rate at the first fluid inlet port of the control device is equal to or greater than L1; the operating mechanism for operating the valve assembly causes the valve assembly to turn down (and in extreme cases close) the first fluid inlet port so that the flow at the first fluid inlet port is less than L1 (and in extreme cases equal to zero), which in turn causes the flow at the first fluid inlet port of the control assembly to be less than L1 (and in extreme cases equal to zero). The reason for limiting the flow at the first fluid inlet end of the valve device to be greater than or equal to L1 by operating the operating mechanism of the valve device and heating the water when the flow at the first fluid inlet end of the control device is greater than or equal to L1 is that the heating device can be prevented from being started by mistake (when some water using parts have fluid leakage or the water tap is not closed tightly or the water supply network has abnormal conditions or a user adjusts the water tap to be fine water flow so as to be beneficial to the survival of fishes in the water tank and the like), and the heating device can be provided with the minimum starting flow (the heating device can be heated under the proper working condition). Meanwhile, the operating mechanism of the valve device is operated to enable the valve device to continuously finish the actions of turning down and turning up the first fluid inlet end within the time T2, so that the flow rate of the first fluid inlet end of the valve device undergoes the continuous change process of the flow rate from equal to or more than L1 to less than L1 within the time T2, then the current flow rate is equal to or more than L1, and the flow rate of the first fluid inlet end of the control device subsequently undergoes the continuous change process of the flow rate from equal to or more than L1 to less than L1 within the time T2, and then the current flow rate is equal to or more than L1. That is, in the winter mode, as long as the operating mechanism of the valve device is operated to open the first fluid inlet end and make the flow rate greater than or equal to L1 (i.e. the operation of opening the faucet to discharge cold water in daily life), the heating device heats to obtain hot water, and when the faucet is opened to obtain cold water, the operating mechanism is operated to perform special actions (turning up-turning down-turning up, and in extreme cases, turning on-off-on) to obtain cold water, so that the cold water can be obtained, which is suitable for the requirements in winter (water used in winter usually prefers to directly use hot water). In addition, because the operation mode of daily habit (namely the operation of opening a faucet to discharge cold water in daily life) is to obtain hot water in a winter mode, cold water can be used if the temperature of the water is higher after the hot water is obtained, and the cold water can be obtained only by operating the operation mechanism to perform special actions (turning up and turning down, and turning off and turning on in extreme cases);

or the condition 9 is that the flow rate monitoring part does not monitor that the flow rate at the first fluid inlet end of the control device undergoes a continuous change process from the flow rate of greater than or equal to L1 to less than L1 within the time T2, and then the current flow rate is greater than or equal to L1, and (i.e. the additional condition 91 of the condition 9) when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from the flow rate of greater than or equal to L1 to less than L1, if the condition 9 is in the satisfied state in the previous stage, the satisfied state continues for the time T5, and if the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from less than L1 to greater than or equal to L1 within the continuation time T5, then the condition 9;

or the condition 9 is that the flow rate monitoring part does not monitor that the flow rate at the first fluid inlet end of the control device undergoes a continuous change from a flow rate of less than L1 to L1 to less than L1 within the time period T2, and then the current flow rate is greater than or equal to L1, and (i.e. the additional condition 91 of the condition 9) when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from L1 to L1, the satisfied state continues for the time period T5 if the condition 9 is satisfied at the previous stage, and the condition 9 continues to be satisfied if the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from L1 to L1 or more during the time period T5.

As a further option 3 of option 2, the control device has a second fluid inlet end as a hot fluid inlet end, a second fluid outlet end as a hot fluid outlet end, the second fluid outlet end is communicated with the second fluid inlet end of the valve device, and the control device controls the heating device to heat when all conditions 1, 9 and 2 are met, and controls the heating device not to heat when any condition 1, 9 or 2 is not met; wherein condition 2 is that the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2. In this solution, the second fluid inlet end of the control device is externally connected to a thermal fluid supply device, for example, various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, and an air energy water heater. Therefore, when the water heater is used for obtaining high-flow hot water, the heating device is closed; in addition, when the hot water quantity of the external hot fluid supply device is insufficient (for example, the hot water quantity of a plurality of water supplies of the hot fluid supply device or the stored hot water quantity of the volume type water heater or the gas quantity of the natural gas water heater is too small) is less than L2, the heating device heats and supplements the hot water.

A further alternative 4 as alternative 2, characterized in that: when all the conditions 1, 9 and 3 are met, the control device controls the heating device to heat, and when any one of the conditions 1, 9 or 3 is not met, the control device controls the heating device not to heat; wherein condition 3 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is less than L3. In this solution, the heating is further restricted when the operating mechanism of the valve device is operated to make the flow rate at the first fluid inlet end of the valve device be a small flow rate (less than L3), and the flow rate at the first fluid inlet end of the control device is a small flow rate (less than L3), so as to meet the daily use habit (the cold water is usually used in a large flow rate, and the hot water is usually used in a small flow rate); meanwhile, under the condition of large flow, the heating temperature is difficult to guarantee due to the fact that the heating device is limited by heating power, the use experience is poor, and the small flow is limited to heat so as to ensure the use experience.

As a further alternative 5 of option 2, the control means controls the heating means to heat when all of the conditions 1, 9 and 4 are satisfied simultaneously, and controls the heating means not to heat when any of the conditions 1, 9 or 4 is not satisfied; wherein condition 4 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is equal to or greater than L4. In this solution, the heating is further limited when the operation mechanism of the valve device is operated to make the flow rate at the first fluid inlet end of the valve device not too small (equal to or greater than L4), and the flow rate at the first fluid inlet end of the control device is then not too small (equal to or greater than L4), because too small flow rate may cause too high temperature of the heating device and too high temperature of the heated water, which is not favorable for normal use of the heating device (aggravating scaling, etc.), and is not favorable for safe use of water (scalding, etc.) for users; in addition, when the faucet is a single-handle dual-valve-core faucet and the second fluid inlet end is externally connected with a hot fluid supply device, when a user wants to use pure hot water, but the operation is not accurate enough, the actual operating mechanism operates the faucet to output cold and hot mixed water, wherein most of the mixed water is hot water, and the small part of the mixed water is cold water, so that the limitation is made for avoiding the false start of the heating device.

As a further alternative 6 of option 4, the control means controls the heating means to heat when all of the conditions 1, 9, 3 and 5 are satisfied simultaneously, and controls the heating means not to heat when any of the conditions 1, 9, 3 or 5 is not satisfied; wherein condition 5 is that the duration of the state that the first fluid inlet end of the control device is monitored by the flow monitoring component to maintain the current flow rate at or above L1 is at or above T1. In the scheme, when a user wants to use cold water, an operating mechanism of the valve device needs to be operated, so that the flow at the first fluid inlet end of the valve device undergoes a continuous change process from the flow being more than or equal to L1 to the flow being less than L1 within the time T2, and then the current flow is more than or equal to L1, and then the flow at the first fluid inlet end of the control device undergoes a continuous change process from the flow being more than or equal to L1 to the flow being less than L1 within the time T2, and then the current flow is more than or equal to L1; in addition, when a user wants to directly use cold water with a large flow rate, the user needs to operate the operating mechanism of the valve device for a period of time to enable the flow rate of the first fluid inlet end of the valve device to be large, the flow rate of the first fluid inlet end of the control device is large, the heating device is controlled not to be heated within the time T1, the heating device can be prevented from being started (started and stopped immediately), and meanwhile, energy is saved.

As a further option 9 of option 1, the control device further comprises a flow monitoring component, the mode shift is switched to the summer mode, and the control device controls the heating device to heat when both conditions 1 and 9 'are met, and controls the heating device not to heat when either condition 1 or condition 9' is not met; the condition 1 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is equal to or greater than L1, the condition 9 'is that the flow monitoring component monitors that the flow at the first fluid inlet end of the control device undergoes a continuous change process from equal to or greater than L1 to equal to or less than L1 within a time T2 and then the current flow is equal to or greater than L1, or the condition 9' is that the flow monitoring component monitors that the flow at the first fluid inlet end of the control device undergoes a continuous change process from less than L1 to equal to or greater than L1 to less than L1 within a time T2 and then the current flow is equal to or greater than L1 (i.e., turn-down-up or turn-up-turn-down-up, and in an extreme case, turn-off or on-off-on). In the scheme, the limitation is that the flow of the first fluid inlet end of the valve device is limited to be larger than or equal to L1 when the operating mechanism of the valve device is operated, and the flow of the first fluid inlet end of the control device is heated when the flow is larger than or equal to L1, so that the reason for limiting is to avoid the false start of the heating device (when some water using components have fluid leakage or a water tap is not closed tightly or a water supply network has abnormal conditions or a user adjusts the water tap to be fine water flow so as to be beneficial to the survival of fishes in the water tank and the like), and the heating device can be provided with the minimum start flow (the heating device can be heated under the appropriate working condition). Meanwhile, in condition 9', in comparison with the winter mode, the summer mode is opposite to the winter mode, and only the operating mechanism of the valve device is operated to enable the valve device to open the first fluid inlet end and enable the flow rate to be greater than or equal to L1 (namely, the operation of opening the faucet to discharge cold water in daily life), the heating device does not heat but directly discharges cold water, and when the faucet is opened to obtain hot water, the operating mechanism is operated to perform special actions (adjustment-reduction-adjustment, and in extreme cases, on-off-on) to obtain hot water, so that the requirement in summer is met (the summer water generally prefers to directly use cold water). In addition, because the operation mode of the daily habit (namely the operation of opening the faucet to discharge cold water in daily life) is to obtain cold water in a summer mode, after the cold water is obtained, if the water temperature is lower and hot water is needed to be used, only the operation mechanism needs to be operated to perform special actions (turning up and turning up, and turning off and turning on in extreme cases) to obtain the hot water;

or the condition 9 ' is that the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device undergoes a continuous change process from the flow rate of more than or equal to L1 to less than L1 within the time T2 and then the current flow rate is more than or equal to L1, and (i.e. the additional condition 9 ' 1 of the condition 9 ') when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from more than or equal to L1 to less than L1, the unsatisfied state continues for the time T5 if the condition 9 ' of the previous stage is unsatisfied, and the condition 9 ' continues to be unsatisfied when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from less than L1 to more than or equal to L1 within the continuation time T5;

or the condition 9 ' is that the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device undergoes a continuous change process from a flow rate of less than L1 to L1 of greater than or equal to and less than L1 within the time period T2, and then the current flow rate is greater than or equal to L1, and (i.e. the additional condition 9 ' 1 of the condition 9 ') when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from L1 of greater than or equal to and less than L1, if the condition 9 ' of the previous stage is in an unsatisfied state, the unsatisfied state continues for the time period T5, and if the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from L1 of less than or equal to L1 of the duration T5, the condition 9 ' continues.

As a further option 10 of option 9, the control device has a second fluid inlet end as the hot fluid inlet end, a second fluid outlet end as the hot fluid outlet end, the second fluid outlet end being in communication with the second fluid inlet end of the valve device, and the control device controls the heating device to heat when all conditions 1, 9 'and 2 are met, and controls the heating device not to heat when any one of conditions 1, 9' or 2 is not met; wherein condition 2 is that the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2. In this solution, the second fluid inlet end of the control device is externally connected to a thermal fluid supply device, for example, various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, and an air energy water heater. Thus, when a large flow of hot water is obtained using the water heater, the heating device is then turned off.

As a further alternative 11 to alternative 9, the control means controls the heating means to heat when all of conditions 1, 9 'and 3 are met simultaneously, and controls the heating means not to heat when any of conditions 1, 9' or 3 are not met; wherein condition 3 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is less than L3. In this solution, the heating is further restricted when the operating mechanism of the valve device is operated to make the flow rate at the first fluid inlet end of the valve device be a small flow rate (less than L3), and the flow rate at the first fluid inlet end of the control device is a small flow rate (less than L3), so as to meet the daily use habit (the cold water is usually used in a large flow rate, and the hot water is usually used in a small flow rate); meanwhile, under the condition of large flow, the heating temperature is difficult to guarantee due to the fact that the heating device is limited by heating power, the use experience is poor, and the small flow is limited to heat so as to ensure the use experience.

As a further alternative 12 of alternative 9, the control means controls the heating means to heat when all of conditions 1, 9 'and 4 are met simultaneously, and controls the heating means not to heat when any of conditions 1, 9' or 4 are not met; wherein condition 4 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is equal to or greater than L4. In this solution, the heating is further limited when the operation mechanism of the valve device is operated to make the flow rate at the first fluid inlet end of the valve device not too small (equal to or greater than L4), and the flow rate at the first fluid inlet end of the control device is then not too small (equal to or greater than L4), because too small flow rate may cause too high temperature of the heating device and too high temperature of the heated water, which is not favorable for normal use of the heating device (aggravating scaling, etc.), and is not favorable for safe use of water (scalding, etc.) for users; in addition, when the faucet is a single-handle dual-valve-core faucet and the second fluid inlet end is externally connected with a hot fluid supply device, when a user wants to use pure hot water, but the operation is not accurate enough, the actual operating mechanism operates the faucet to output cold and hot mixed water, wherein most of the mixed water is hot water, and the small part of the mixed water is cold water, so that the limitation is made for avoiding the false start of the heating device.

As a further alternative 13 of alternative 11, the control means controls the heating means to heat when all of conditions 1, 9 ', 3 and 5 are satisfied simultaneously, and controls the heating means not to heat when any of conditions 1, 9', 3 or 5 are not satisfied; wherein condition 5 is that the duration of the state that the first fluid inlet end of the control device is monitored by the flow monitoring component to maintain the current flow rate at or above L1 is at or above T1. In the scheme, when a user wants to directly use cold water with a large flow rate, the user needs a period of operation time (T1) to operate the operating mechanism of the valve device to enable the flow rate of the first fluid inlet end of the valve device to be large, the flow rate of the first fluid inlet end of the control device is large, the heating device is controlled not to be heated in the period of time (T1), the heating device can be prevented from being started inefficiently (started and stopped immediately), and meanwhile, energy is saved.

As a further alternative 16 of option 1, the control device further comprises a flow monitoring component, the mode shift is switched to the four season a mode, and the control device controls the heating device to heat when conditions 1, 5 and 6 are met, and controls the heating device not to heat when any one of conditions 1, 5 or 6 is not met; wherein, the condition 1 is that the current flow rate monitored by the flow monitoring component at the first fluid inlet end of the control device is greater than or equal to L1, the condition 5 is that the duration of the first fluid inlet end of the control device monitored by the flow monitoring component in the state that the current flow rate is greater than or equal to L1 is greater than or equal to T1, and the condition 6 is that the current flow rate monitored by the flow monitoring component at the first fluid inlet end of the control device in the state that the current flow rate is greater than or equal to L1 to time T1 is less than L3. In the scheme, the limitation is performed when the flow of the first fluid inlet end of the valve device is enabled to be larger than or equal to L1 by operating an operating mechanism of the valve device, and the flow of the first fluid inlet end of the control device is heated when the flow of the first fluid inlet end of the valve device is larger than or equal to L1, so that the limitation is performed because the heating device can be prevented from being started by mistake (when certain water using components have fluid leakage or a water tap is not closed tightly or a water supply network has abnormal conditions or a user adjusts the water tap to be fine water flow so as to be beneficial to the survival of fishes in the water tank and the like), and the heating device can be provided with the. In addition, an operating mechanism of the valve device is operated to adjust the flow of the first fluid inlet end of the valve device to a flow suitable for the water demand at the moment (namely, daily faucet opening and appropriate flow adjustment are carried out) usually, a period of time is required, the current flow at the time of T1 is taken as a judgment standard, namely, the current flow at the time of T1 is smaller than L3 for heating, the current flow at the time of T1 is larger than or equal to L3 for not heating, and the valve device accords with daily use habits (cold water is usually expected to be large flow, hot water is usually small flow), meanwhile, the heating temperature of the heating device is limited by heating power at large flow, the use experience is not good, and the heating is ensured only by limiting small flow; for this reason, when the flow monitoring part monitors that the first fluid inlet end of the control device keeps the current flow rate being equal to or more than L1 for a time period being equal to or more than T1, the heating is not carried out before the time period, so that the heating device is prevented from being started inefficiently (started and stopped immediately) and energy is saved. In particular, if the current flow rate is equal to or greater than L3 at T1 without heating (condition 6 selects no heating), the non-heating state continues to the end of the state where the first fluid inlet end of the valve device continuously maintains the current flow rate equal to or greater than L1, after which (after the time point of T1) no heating occurs even if the current flow rate at the first fluid inlet end is less than L3, i.e., cold water with different flow rates can be obtained at will during this period; if the current flow rate is less than L3 heating at T1 (condition 6 selects heating), the heating state continues to the end of the state that the first fluid inlet end of the valve device continuously maintains the current flow rate equal to or greater than L1, and then (after the time point of T1) the first fluid inlet end is heated even if the current flow rate is equal to or greater than L3, i.e. hot water with different flow rates can be obtained randomly in the period;

or the condition 6 is that the current flow rate is less than L3 when the flow rate monitoring part monitors that the first fluid inlet end of the control device keeps the current flow rate being greater than or equal to L1 to the time T1, and (i.e. the additional condition 61 of the condition 6) when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from being greater than or equal to L1 to being less than L1, the condition 6 is satisfied or not satisfied for the time T5 if the condition 6 is satisfied or not in the previous stage, and the condition 6 is still satisfied or not satisfied when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from being less than L1 to being greater than or equal to L1 in the continuation time T5.

As a further option 17 of option 16, the control device has a second fluid inlet end as the hot fluid inlet end, a second fluid outlet end as the hot fluid outlet end, the second fluid outlet end being in communication with the second fluid inlet end of the valve device, and the control device controls the heating device to heat when all of conditions 1, 5, 6, and 2 are met, and controls the heating device not to heat when any of conditions 1, 5, 6, or 2 is not met; wherein condition 2 is that the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2. In this solution, the second fluid inlet end of the control device is externally connected to a thermal fluid supply device, for example, various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, and an air energy water heater. Thus, when a large flow of hot water is obtained using the water heater, the heating device is then turned off.

A further alternative 18 of alternative 16 wherein the control means controls the heating means to heat when all of conditions 1, 5, 6 and 3 are met, and wherein the control means controls the heating means not to heat when any of conditions 1, 5, 6 or 3 are not met; wherein condition 3 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is less than L3. In this solution, the heating is further restricted when the operating mechanism of the valve device is operated so that the current flow rate at the first fluid inlet end of the valve device is less than L3, and the current flow rate at the first fluid inlet end of the control device is less than L3, according to the daily usage habit (the usage of cold water is usually expected to be a large flow rate, and the usage of hot water is usually a small flow rate); meanwhile, under the condition of large flow, the heating temperature is difficult to guarantee due to the fact that the heating device is limited by heating power, the use experience is poor, and the small flow is limited to heat so as to ensure the use experience. In particular, if the current flow rate is equal to or greater than L3 at T1 without heating (condition 6 selects no heating), the non-heating state continues to the end of the state where the first fluid inlet end of the valve device continuously maintains the current flow rate equal to or greater than L1, after which (after the time point of T1) no heating occurs even if the current flow rate at the first fluid inlet end is less than L3, i.e., cold water with different flow rates can be obtained at will during this period; if the current flow rate is less than L3 heating at T1 (heating is selected in condition 6), after which (after time T1) the current flow rate at the first fluid inlet end is less than L3 heating, after which (after time T1) the current flow rate at the first fluid inlet end is equal to or greater than L3 unheating.

As a further alternative 19 of alternative 16, the control means controls the heating means to heat when all of conditions 1, 5, 6 and 4 are met simultaneously, and the control means controls the heating means not to heat when any of conditions 1, 5, 6 or 4 are met; wherein condition 4 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is equal to or greater than L4. In this solution, the flow rate at the first fluid inlet end of the valve device is further limited to be not too small (equal to or greater than L4) by operating the operating mechanism of the valve device, and the flow rate at the first fluid inlet end of the control device is heated when the flow rate is not too small (equal to or greater than L4), because too small flow rate may cause too high temperature of the heating device and too high temperature of the heated water, which is not favorable for normal use of the heating device (scaling and the like), and is not favorable for safe use of water (scalding and the like) by users; in addition, when the faucet is a single-handle dual-valve-core faucet and the second fluid inlet end is externally connected with a hot fluid supply device, when a user wants to use pure hot water, but the operation is not accurate enough, the actual operating mechanism operates the faucet to output cold and hot mixed water, wherein most of the mixed water is hot water, and the small part of the mixed water is cold water, so that the limitation is made for avoiding the false start of the heating device.

As a further alternative 23 of option 1, the control device further comprises a flow monitoring component, the mode shift is switched to the four season B mode, and the control device controls the heating device to heat when all conditions 1 and 3 are met, and controls the heating device not to heat when any one of the conditions 1 or 3 is not met; wherein condition 1 is that the flow monitoring component monitors that the current flow rate at the first fluid inlet end of the control device is equal to or greater than L1, and wherein condition 3 is that the flow monitoring component monitors that the current flow rate at the first fluid inlet end of the control device is less than L3.

In addition, the heating is performed when the flow rate at the first fluid inlet end of the valve device is limited to be less than L3 by operating the operating mechanism of the valve device, and the flow rate at the first fluid inlet end of the control device is less than L3, so that the daily use habit is met (the cold water is generally expected to be a large flow rate, and the hot water is generally a small flow rate); meanwhile, under the condition of large flow, the heating temperature is difficult to guarantee due to the fact that the heating device is limited by heating power, the use experience is poor, and the small flow is limited to heat so as to ensure the use experience.

As a further option 24 of option 23, the control device has a second fluid inlet end as the hot fluid inlet end, a second fluid outlet end as the hot fluid outlet end, the second fluid outlet end being in communication with the second fluid inlet end of the valve device, and the control device controls the heating device to heat when all of conditions 1, 3, and 2 are met, and controls the heating device not to heat when any of conditions 1, 3, or 2 is not met; wherein condition 2 is that the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2.

As a further alternative 25 of alternative 23, the control means controls the heating means to heat when all of conditions 1, 3 and 4 are met simultaneously, and controls the heating means not to heat when any of conditions 1, 3 or 4 are not met; wherein condition 4 is that the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is equal to or greater than L4. In this solution, the flow rate at the first fluid inlet end of the valve device is further limited to be not too small (equal to or greater than L4) by operating the operating mechanism of the valve device, and the flow rate at the first fluid inlet end of the control device is heated when the flow rate is not too small (equal to or greater than L4), because too small flow rate may cause too high temperature of the heating device and too high temperature of the heated water, which is not favorable for normal use of the heating device (scaling and the like), and is not favorable for safe use of water (scalding and the like) by users; in addition, when the faucet is a single-handle dual-valve-core faucet and the second fluid inlet end is externally connected with a hot fluid supply device, when a user wants to use pure hot water, but the operation is not accurate enough, the actual operating mechanism operates the faucet to output cold and hot mixed water, wherein most of the mixed water is hot water, and the small part of the mixed water is cold water, so that the limitation is made for avoiding the false start of the heating device.

As a further alternative 26 of option 23, the control means controls the heating means to heat when all of conditions 1, 3 and 5 are met simultaneously, and controls the heating means not to heat when any of conditions 1, 3 or 5 are not met; wherein condition 5 is that the duration of the state that the first fluid inlet end of the control device is monitored by the flow monitoring component to maintain the current flow rate at or above L1 is at or above T1. In the scheme, when a user wants to use cold water with large flow, the operating mechanism of the valve device is operated to enable the flow of the first fluid inlet end of the valve device to be large, the flow of the first fluid inlet end of the control device is large, a period of operating time (T1) is needed, the heating device is controlled not to be heated in the period of time (T1), the heating device can be prevented from being started inefficiently (started and stopped immediately), and meanwhile, energy is saved.

As a further option 28 of option 1, the valve device is a stand-alone complete faucet. In the scheme, the difference is that the electric heating faucet/instant heating type faucet in the prior art is the combination of a common faucet and a heating module, and the valve device in the invention is a common faucet which is a conventional product known by persons skilled in the art.

As a further option 29 of option 28, the faucet is a single handle dual spool faucet having one fluid outlet end, and a first fluid inlet end of the cold fluid inlet end and a second fluid inlet end of the hot fluid inlet end; or the faucet is a single cold faucet having a fluid outlet end and a fluid inlet end of the cold fluid inlet end; or the water faucet is a double-handle double-valve-core water faucet and comprises a cold water control handle, a hot water control handle, a cold water valve core and a hot water valve core, wherein the double-handle double-valve-core water faucet is provided with a fluid outlet end, a first fluid inlet end of a cold fluid inlet end and a second fluid inlet end of a hot fluid inlet end; or the faucet is a pull-out hot and cold faucet having one fluid outlet end, a first fluid inlet end of the cold fluid inlet end and a second fluid inlet end of the hot fluid inlet end. In the scheme, as mentioned above, the invention is suitable for the single-cold water faucet, and cold fluid/cold water or hot fluid/hot water can be obtained at will; the valve is suitable for a single-handle duplex valve core faucet or a double-handle duplex valve core faucet or a drawing type cold and hot water faucet, and cold fluid/cold water or hot fluid/hot water or warm fluid/warm water can be obtained by switching at will.

As a further option 30 of option 29, the hot fluid inlet end of the faucet is in communication with a hot water outlet end of a hot fluid supply. In the scheme, the hot fluid supply device is matched for use, and cold fluid/cold water or hot fluid/hot water or warm fluid/warm water can be obtained by switching at will.

As a further option 31 of option 1, the heating device is an independent tankless small kitchen appliance, and the control device is a device separate from the tankless small kitchen appliance; or the control device is integrated into the instant heating type small kitchen appliance. In the scheme, the small kitchen appliance is a commodity ' instant-heating type small kitchen appliance ' sold in the market in the prior art, and the instant-heating type small kitchen appliance ' is a type product name of a class of commodities sold in the market and is a conventional product known by technical personnel in the field.

As a further alternative 32 to the previous alternative, the second fluid inlet port of the control device is in communication with a hot water outlet port of a hot fluid supply device.

As a further alternative 33 to the previous option, the valve means is exposed outside its mounting platform, and the heating means and control means are hidden below this mounting platform.

In the heating method of the fluid heating apparatus in the above selection, the operating mechanism of the valve device controls the flow rate change at the first fluid inlet end, the flow rate at the first fluid inlet end of the control device changes accordingly, and the control device senses the flow rate change at the first fluid inlet end and correspondingly controls the heating device accordingly.

Alternatively 1', operating the operating mechanism of the valve device to make the valve device continuously complete the actions of turning down and turning up the first fluid inlet end within the time T2, so that the flow rate at the first fluid inlet end undergoes the continuous change process from the flow rate of greater than or equal to L1 to less than L1 within the time T2, and then the current flow rate is greater than or equal to L1, and then the flow rate at the first fluid inlet end of the control device undergoes the continuous change process from the flow rate of greater than or equal to L1 to less than L1 within the time T2, and then the current flow rate is greater than or equal to L1; or the operating mechanism of the valve device is operated to make the valve device continuously finish the actions of increasing, decreasing and finally increasing the first fluid inlet end within the time T2, so that the flow rate of the first fluid inlet end of the valve device undergoes the continuous change process of the flow rate from less than L1 to equal to or more than L1 to less than L1 and then the current flow rate is equal to or more than L1 within the time T2, and the flow rate of the first fluid inlet end of the control device subsequently undergoes the continuous change process of the flow rate from less than L1 to equal to or more than L1 to less than L1 and then the current flow rate is equal to or more than L1 within the time T2.

Alternatively 2', operating the operating mechanism of the valve means to cause the valve means to open the first fluid inlet port such that the flow at the first fluid inlet port is equal to or greater than L1, the flow at the first fluid inlet port of the control means being equal to or greater than L1; the operating mechanism for operating the valve assembly causes the valve assembly to turn down (and in extreme cases close) the first fluid inlet port so that the flow at the first fluid inlet port is less than L1 (and in extreme cases equal to zero), which in turn causes the flow at the first fluid inlet port of the control assembly to be less than L1 (and in extreme cases equal to zero).

Alternatively 3', operating the operating mechanism of the valve arrangement causes the valve arrangement to open the first fluid inlet port for a time period T1 such that its first fluid inlet port remains in a condition at the current flow rate of L1 or greater for a time period T1, whereupon the first fluid inlet port of the control arrangement remains in a condition at the current flow rate of L1 or greater for a time period T1.

In order to clearly understand the conditions in the present invention, as described above, the present invention has a concept of "stage", in which the flow monitoring unit continuously maintains the flow rate at the first fluid inlet end of the control device at L1 or higher as a stage, that is, starting from a recorded state at L1 or higher (typically, when the flow rate changes from L1 to L1, the L1 is used as a boundary), the flow monitoring unit continuously maintains L1 or higher, and once the flow rate changes from L1 to L1 (the L1 is used as a boundary), the flow monitoring unit ends. When the flow rate changes from less than L1 to equal to or more than L1 again (taking L1 as a boundary point), the next stage starts again. As is clear from the above concept, the phase concept of the present invention corresponds to the condition 1, and the period satisfying the condition 1 is taken as the phase with the condition 1 as the criterion for determining the phase. And why the concept of the generation phase is not artificially defined, but is naturally the inevitable result, because the condition 1 is the basic condition of the present invention, the satisfaction of the condition 1 needs to judge whether other conditions are satisfied, and if the condition 1 is not satisfied, the judgment of whether other conditions are satisfied is not needed at all.

Because the judgment modes and purposes of all the conditions are different, the judgment of whether all the conditions are effective is also different, and specifically: according to the characteristics of the judgment mode and the purpose of the condition, in a stage, the condition 9 'and the condition 6 are continuously effective until the stage is ended, namely when the stage is started, if the condition 9, the condition 9' and the condition 6 are judged to be satisfied, the satisfied state is kept until the stage is ended; similarly, if condition 6 is satisfied during a phase, this satisfied state will also remain until the end of the phase; specifically, the condition 9 and condition 9 'determination points are the starting points of the stage, that is, whether the condition 9 and the condition 9' are satisfied is determined at the start of the stage; the condition 6 determination point is at time T1, i.e., at time T1, and it is determined whether or not the condition 6 is satisfied. Conversely, if condition 9, condition 9', condition 6 are determined to be not satisfied, then this non-satisfied state is maintained until the end of the phase. At the beginning of the next phase, it will be determined again whether conditions 9, 9' and 6 are satisfied, and this satisfied state is maintained for the whole phase. Namely, the condition 9' and the condition 6 are characterized by one judgment, and the judgment result is continuously effective in the whole stage. The condition 5 is similar to but different from the conditions 9, 9' and 6, and the condition 5 is determined in such a manner that the condition 5 is not satisfied due to insufficient time from the start of the stage to the T1, and the condition 5 is satisfied at and after the T1 and the satisfied state is maintained until the end of the stage. In the four season a mode, the condition 6 determination point is the T1 th time point, and the control device controls the heating device not to heat up from the stage start to the T1 th time point because the condition 5 is not satisfied, that is, all the conditions (any one of the conditions is not satisfied) are not satisfied at the same time, and the condition 5 and the condition 6 are used at the same time in the four season a mode and cannot be used alone.

And similarly, according to the characteristics of the judgment mode and the purpose of the condition, the conditions 2, 3 and 4 are continuously judged in the whole stage, the judgment result is continuously changed, and once the conditions are changed, the judgment result is changed accordingly. For example, the condition 2 is determined by whether the current flow rate is less than L2, the condition 2 is satisfied when the current flow rate is less than L2, the condition 2 is not satisfied when the flow rate becomes equal to or greater than L2, and the condition 2 is restored to the satisfied state when the flow rate is restored to less than L2.

After the above procedure is set, the heating device is controlled by the operation trigger control device of the operating mechanism of the valve device of the present invention.

The valve device generally includes a control handle as an operating mechanism, and a valve core controlled by the control handle, and the passing condition of fluid through the valve core, such as valve on-off, flow rate and the like, is adjusted by operating the control handle. A heating device is a device for heating a fluid flowing through the device, in particular through the device from the inside thereof. The valve device and the heating device have various structures and forms in the prior art, and can be used in the invention as long as the valve device and the heating device are applicable to the scheme of the invention. The operating mechanism of the valve device comprises a conventional operating mechanism, such as a control handle of a faucet, but since the flow rate of the first fluid inlet port is also varied by operating the components of the faucet, such as the spout, the bubbler and the flow restrictor, at the outlet of the faucet, the operating mechanism of the valve device also comprises the components of the faucet, such as the spout, the bubbler and the flow restrictor, at the outlet of the faucet. That is, the operation mechanism of the valve device controls the flow change of the first fluid inlet end, and also includes components such as a water outlet nozzle, a bubbler and a flow restrictor at the water outlet of the valve device such as a faucet, and the flow change of the first fluid inlet end is controlled by adjusting or switching the components.

Preferably, the valve device is a self-contained faucet, and the fluid outlet end of the valve device is a faucet water outlet, the cold fluid inlet end of the valve device is a cold water inlet, and the hot fluid inlet end of the valve device is a hot water inlet. The faucet is different from the prior art electric heating faucet/instant heating faucet, and is a combination of a common faucet and a heating module, and the valve device of the embodiment is a common faucet, which is a conventional product known to those skilled in the art.

Preferably, the valve means is exposed on its mounting platform, for example on a cupboard or wash basin counter, and the heating means and control means are concealed beneath the mounting platform, for example in the cabinet under the cupboard counter or in the cabinet under the wash basin counter.

Preferably, the faucet is a single-handle dual-valve-core faucet, the operating mechanism is a control handle of the faucet, the faucet is provided with a fluid outlet end, a first fluid inlet end of the cold fluid inlet end and a second fluid inlet end of the hot fluid inlet end, and cold fluid/cold water or hot fluid/hot water can be obtained randomly.

The water tap can also be a single-cold water tap, the operating mechanism is a control handle of the water tap, and the water tap is provided with a fluid outlet end and a fluid inlet end of the cold fluid inlet end; the water faucet can also be a double-handle double-valve-core water faucet, the operating mechanism comprises a cold water operating handle and a hot water operating handle, the valve core comprises a cold water valve core and a hot water valve core, and the double-handle double-valve-core water faucet is provided with a fluid outlet end, a first fluid inlet end of the cold fluid inlet end and a second fluid inlet end of the hot fluid inlet end; the faucet can also be a common pull-out type cold and hot water faucet, the common pull-out type cold and hot water faucet also comprises a fluid outlet end, a first fluid inlet end of a cold fluid inlet end and a second fluid inlet end of a hot fluid inlet end, so the common pull-out type cold and hot water faucet is called a pull-out type faucet because a pull-out pipe which can be pulled out or retracted from a water outlet end of the faucet is arranged (usually, a falling body which can slide on the outer surface of the pull-out pipe is further sleeved on the pull-out pipe, the pull-out pipe is successfully retracted after being pulled out by utilizing the gravity provided by the falling body), one end of the pull-out pipe leads to a valve. The hot fluid inlet end of the faucet is communicated with the hot water outlet end of a hot fluid supply device, and the common hot fluid supply device in daily life is various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, an air energy water heater and the like. Meanwhile, the device is matched with a hot fluid supply device for use, and cold fluid/cold water or hot fluid/hot water or warm fluid/warm water can be obtained by switching at will.

Preferably, the heating device is an independent instant heating type small kitchen appliance, and the control device is a device separated from the instant heating type small kitchen appliance; or the control device is integrated into the instant heating type small kitchen appliance. The instant heating type small kitchen appliance of the embodiment is a commercial product "instant heating type small kitchen appliance" in the prior art, and the instant heating type small kitchen appliance "is a product name (also called other name, but the name is the most common) of a commercial product of the prior art, and is a conventional product known to those skilled in the art, such as a flying FY-18SNOX-34 instant heating type electric water heater (small kitchen appliance), and ottron S16D-Z55A instant heating type small kitchen appliance. The instant heating type small kitchen appliance is internally provided with an electric heating module for heating water, and the electric heating module also has a plurality of specific forms, such as a stainless steel heating pipe, a thick film heating pipe, a cast aluminum heater, a heating wire and the like. The instant small kitchen appliance usually further comprises a control module and a switch, wherein the control module usually monitors fluid temperature, heating body temperature, fluid pressure, resistivity of a water supply source and the like to determine whether the instant small kitchen appliance starts heating or stops heating and the like. Specifically, the heating device and the control device of the present invention are variously coupled, and as an example: in an example, the heating device may be controlled by the control device giving a heating signal, or the heating device may be controlled by the control device giving a non-heating signal. When the control device gives a heating signal, the heating device can heat according to the signal, and can also select heating or non-heating according to the signal according to the working condition of the heating device, and when the control device does not give the heating signal, the heating device does not heat; or when the control device gives a non-heating signal, the heating device does not heat, when the control device does not give the non-heating signal, the heating device can heat according to the signal, and the heating device can select heating or non-heating according to the signal according to the working condition of the heating device. In the second example, if the heating device is an independent instant-heating type small kitchen appliance and the control device is a device separated from the instant-heating type small kitchen appliance, the control device may give a heating signal and input the signal into the instant-heating type small kitchen appliance to control the instant-heating type small kitchen appliance, or the control device may give a non-heating signal and input the signal into the instant-heating type small kitchen appliance to control the instant-heating type small kitchen appliance. The instant heating type small kitchen appliance is heated when receiving the heating signal given by the control device and self-checking the heating signal to be normal and meeting self starting conditions, and the instant heating type small kitchen appliance is not heated when not receiving the heating signal given by the control device; or the instant heating type small kitchen appliance does not heat when receiving the non-heating signal given by the control device, and the instant heating type small kitchen appliance heats when not receiving the non-heating signal given by the control device and self-checking normally and according with self-starting conditions. In the third example, if the control device is integrated into the instant small kitchen appliance, the control device gives a heating signal to control the instant small kitchen appliance, or the control device gives a non-heating signal to control the instant small kitchen appliance. The instant heating type small kitchen appliance gives a heating signal to the control device and heats when the self-checking is normal and meets the starting condition, and the instant heating type small kitchen appliance does not heat when the control device does not give the heating signal; or the instant heating type small kitchen appliance does not heat when the control device gives a non-heating signal, and the instant heating type small kitchen appliance heats when the control device does not give the non-heating signal and the self-checking is normal and meets the starting condition. Self-checking of the tankless mini-chef-bao itself generally includes: fluid temperature, heater temperature, fluid pressure, resistivity of the water supply, etc. Particularly, if the heating device is an independent instant-heating type small kitchen appliance, and the control device is a device separated from the instant-heating type small kitchen appliance, a non-heating signal is given by the control device and is input into the instant-heating type small kitchen appliance to control the instant-heating type small kitchen appliance, the heating device can be an independent and complete instant-heating type small kitchen appliance, and the control device can be a device independent from the instant-heating type small kitchen appliance because of signal input (non-heating signal) between the control device and the instant-heating type small kitchen appliance, the instant-heating type small kitchen appliance can normally operate (the instant-heating type small kitchen appliance heats when self-checking is normal and accords with self starting conditions, otherwise, the instant-heating type small kitchen appliance does not heat). The signal input between the cut-off control device and the instant-heating type small kitchen appliance can adopt cut-off signal input (a group of plugs and jacks can be arranged on a signal line between the control device and the instant-heating type small kitchen appliance in a signal line input mode, the signal transmission between the control device and the instant-heating type small kitchen appliance can be cut off by pulling out the plugs from the jacks, the signal transmission between the control device and the instant-heating type small kitchen appliance can also be cut off by cutting off the signal line, and a transmitter on the control device or a receiver on the instant-heating type small kitchen appliance is closed in a wireless signal input mode) or a power supply of the control device is closed (the control device does not output a non-heating signal).

In this embodiment, by arranging the heating device upstream of the cold fluid inlet end of the valve device, the operation of the operating mechanism of the valve device triggers the control device to control the heating device (e.g. control whether the heating device is heated or not, or even further heating power and heating time, etc.), so that the free and fast control that heating is desired and heating is not desired can be realized while the valve is operated (e.g. switching the valve, adjusting the flow rate or adjusting the type of fluid, etc.) by using the operating mechanism of the existing valve, and the operating mechanism of the valve device can be freely and fast operated to obtain cold fluid/cold water or hot fluid/hot water. Specifically, the operating mechanism of the valve device controls the flow change at the first fluid inlet end, the flow at the first fluid inlet end of the control device changes along with the flow change, and the control device senses the flow change at the first fluid inlet end and correspondingly controls the heating device according to the flow change. For example, an operation A of the operating mechanism of the valve device triggers the control device to control the heating device to heat, an operation B of the operating mechanism of the valve device triggers the control device to control the heating device not to heat, an operation C of the operating mechanism of the valve device triggers the control device to control the heating device to increase the heating power, an operation C' of the operating mechanism of the valve device triggers the control device to control the heating device to decrease the heating power, and so on.

Preferably, the control device has mode shifts including one or more of a winter mode, a summer mode, a four season a mode and a four season B mode. The control device can have one of two or three mode gears, and if the multi-mode gears can be switched by means of a mode selector switch, the mode selector switch is not provided if only one mode gear is provided. The mode changing switch can be implemented by various existing devices and known methods in the prior art, such as an inhibitor switch, a touch switch, and the like. In this embodiment, the mode shift is switched to the winter mode, the control device further includes a flow monitoring component, and the control device controls the heating device to heat when conditions 1 and 9 are satisfied, and controls the heating device not to heat when conditions 1 or 9 are not satisfied; wherein condition 1 is that the flow monitoring component monitors that the current flow rate at the first fluid inlet end of the control device is equal to or greater than L1, and condition 9 is that the flow monitoring component does not monitor that the flow rate at the first fluid inlet end of the control device undergoes a continuous change from equal to or greater than L1 to less than L1 within the time T2 and then the current flow rate is equal to or greater than L1. The flow monitoring component can be implemented by various existing devices and known methods in the prior art, such as reed pipe flow switches, hall flow switches, magnetic flow switches, hall flow sensors, pulsed flow sensors, and the like.

In this embodiment, the operating mechanism of the valve device is operated to cause the valve device to open the first fluid inlet port such that the flow rate at the first fluid inlet port is equal to or greater than L1, and the flow rate at the first fluid inlet port of the control device is equal to or greater than L1; operating the operating mechanism of the valve means to cause the valve means to regulate the flow at the first fluid inlet port to less than L1, which in turn causes the flow at the first fluid inlet port of the control means to be less than L1; the operating mechanism of the valve means is operated to cause the valve means to close the first fluid inlet port so that the flow at the first fluid inlet port is equal to zero, and the flow at the first fluid inlet port of the control means is subsequently equal to zero. The operation mechanism of the valve device is operated to make the valve device continuously finish the actions of reducing and then increasing the first fluid inlet end within the time T2 and make the flow rate be more than or equal to L1 (for the daily lift-up type single cold water faucet, the handle is lifted up to open the faucet and the flow rate be more than or equal to L1, then the handle is pressed down to close the faucet, then the handle is lifted up again to open the faucet and the flow rate be more than or equal to L1; for the daily lift-up type single handle dual valve core faucet, the handle is firstly turned right to a cold water area where only cold water is discharged from a water outlet, at the moment, the water outlet is only communicated with the cold water inlet through a channel, then the handle is lifted up to open the faucet and the flow rate be more than or equal to L1, then the handle is pressed down to close the faucet, then the handle is lifted up again to open the faucet and the flow rate be more than or equal to L1; for, then the cold water control handle is rotated towards the opening direction to open the faucet and the flow rate is more than or equal to L1, then the cold water control handle is rotated towards the closing direction to close the faucet, and the cold water control handle is rotated towards the opening direction again to open the faucet and the flow rate is more than or equal to L1; the specific structure of the pull-out type cold and hot water faucet generally comprises a pull-out type cold and hot water faucet with a lift-open type single-handle double-valve core structure and a pull-out type cold and hot water faucet with a rotary type double-handle double-valve core structure, the operation modes of the pull-out type cold and hot water faucet with the rotary type double-valve core structure are respectively the same as the operation modes of the single-handle double-valve core faucet and the double-handle double-valve core faucet), so that the flow at the first fluid inlet end of the pull-out type cold and hot water faucet undergoes a continuous change process of the flow from L1 to L1 or more within the time T2, and then the current flow is greater than or equal to L1, and the flow at the first fluid inlet end of the control device undergoes a continuous change process. That is, when hot water is desired to be obtained in the winter mode, the heating device heats the hot water by operating the operating mechanism of the valve device to open the first fluid inlet port and make the flow rate equal to or greater than L1 (i.e., a daily operation of opening the faucet to discharge cold water). When the tap is opened to obtain cold water, the operating mechanism is operated to perform special actions (turning up-turning down-turning up, and in extreme cases turning on-off-on) to obtain the cold water, so that the cold water is suitable for the requirements in winter (the water used in winter usually likes directly using hot water). In addition, since the operation manner of the daily habit (i.e., the operation of opening the faucet to discharge cold water in daily life) is to obtain hot water in the winter mode, cold water can be used if the temperature of the water is sensed to be high after the hot water is obtained, and the cold water can be obtained only by operating the operation mechanism to perform special actions (turning up and turning down, and turning off and on in extreme cases). In this embodiment, L1 is preferably 1.2 liters/minute and T2 is preferably 2 seconds.

In this embodiment, the condition 9 determination point is the start point of the phase, that is, it is determined whether the condition 9 is satisfied at the start of the phase, and the determination result is continuously valid in the whole phase.

Fig. 2 is a circuit diagram of embodiment 1, in which the circuit diagram of this embodiment controls the heating device by outputting a heating signal, and may also control the heating device by outputting a non-heating signal (the method for outputting a non-heating signal may refer to embodiment 10, and the method for outputting a non-heating signal is similar in other embodiments and is not described again). In addition, in this embodiment, the control scheme is implemented by using separate elements such as a flow switch, an intermediate relay, and a time relay, or by using an integrated element such as a flow sensor and a single chip (or PLC).

In the circuit diagram, K1 is a normally open contact of a flow rate monitoring part (a clarinet magnetic type water flow switch) provided at a first fluid inlet end of the control device, JR1 and JR5 are intermediate relays, JS2 is a slow-suction relay whose slow-suction time is T2, and JS3 is a slow-suction relay whose slow-suction time is T3 (not more than 0.05 second) should be longer than a time required for a switching action of the relay contacts (usually not more than 0.02 second) (the slow-suction time T3 is set so as to ensure that a control coil of the JR5 is turned on and form a self-locking circuit when the relevant relay contacts are switched according to a set condition in the present embodiment, and for this reason, T3, for example, T3 is set to 0.04 second according to a time required for the switching action of the contacts of JR1, JR5, JS2, and JS3 in the.

In a normal condition (the faucet is opened after T2 time since the previous water use is finished and closed), when hot water is obtained, the faucet can be directly opened, when the flow monitoring part monitors that the current flow at the first fluid inlet end of the control device is greater than or equal to L1, the normally open contact K1 is closed/the JR1 control coil is conducted, and the normally open contact JR1-1 is closed (the condition 1 is met)/the JS3 control coil is conducted; when the flow monitoring component does not monitor that the flow at the first fluid inlet end of the control device undergoes a continuous change process from the flow being greater than or equal to L1 to the flow being less than L1 within T2 and then the current flow is greater than or equal to L1, the slow suction normally-closed contact JS3-2 (the delayed opening is instantaneously closed) is delayed to be opened and continuously in a closed state/JS 2 control coil to be continuously conducted within the slow suction time T3, the slow suction normally-open contact JS2-1 is closed/normally-open contact JR1-1 is closed/JR 5 control coil is conducted (and a self-locking circuit is formed until the normally-open contact JR1-1 is opened), and the normally-open contact JR5-1 is closed (condition 9 is met). When the condition 1 and the regulation 9 are simultaneously met, the normally open contact JR1-1 is closed/the normally open contact JR5-1 is closed/JR 10 controls the coil to be conducted, and the normally open contact JR10-1 is closed (a heating signal is given).

Under the normal condition (the water faucet is turned on after T2 time since the water faucet is turned off for the last time), after the water faucet is turned on, the water faucet is turned down (in an extreme case, the water faucet is turned off) within T2 time and then the water faucet is turned on again, when the flow monitoring part monitors that the flow at the first fluid inlet end of the control device undergoes a continuous change process from the flow being greater than or equal to L1 to the flow being less than L1 within T2 time, then the current flow is greater than or equal to L1, the JS2 control coil gets an electric conduction change process again after the power is lost within T2 time, a slow suction normally open contact JS2-1 (delayed closing instant opening) is delayed to be closed within a slow suction time T2 to be continuously in an open state/JR 5 control coil is not conducted, and the normally open contact JR5-1 is opened (condition 9 is not met). When the condition 1 and the adjustment 9 are not simultaneously met, the normally open contact JR1-1 is closed/the normally open contact JR5-1 is opened/the JR10 controls the coil to be not conducted, and the normally open contact JR10-1 is opened (no heating signal is given).

In the present embodiment, the aforementioned "normal condition", "directly turn on the faucet", "obtain hot water", and "non-normal condition" (turn on the faucet within a time T2 since the faucet was turned off after the previous water use) "directly turn on the faucet", which is equivalent to the flow monitoring means monitoring that the flow at the first fluid inlet end of the control device undergoes a continuous change from a flow of L1 or more to a flow of less than L1 and then the current flow of L1 or more during a time T2, and then "obtain cold water".

In the embodiment, the normally open contact JR10-1 is closed to give a heating signal to the control device, and the heating device can heat according to the signal and also can select heating or non-heating according to the signal according to the working condition of the heating device; the normally open contact JR10-1 is opened, so that the control device does not give a heating signal, and the heating device does not heat. The working condition of the heating device generally includes whether self-checking is normal or not, whether a starting condition is met or not, and the like.

Example 2: referring to fig. 3, this embodiment is similar to embodiment 1 except that: the control device is provided with a second fluid inlet end which is a hot fluid inlet end, a second fluid outlet end which is a hot fluid outlet end, the second fluid outlet end is communicated with the second fluid inlet end of the valve device, the control device controls the heating device to heat when all conditions 1, 9 and 2 are met, and the control device controls the heating device not to heat when any condition 1, 9 or 2 is not met; wherein condition 2 is that the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2. In this embodiment, the second fluid inlet of the control device is externally connected to a thermal fluid supply device, for example, various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, and an air energy water heater. Therefore, when the water heater is used for obtaining high-flow hot water, the heating device is closed; in addition, when the hot water quantity of the external hot fluid supply device is insufficient (for example, the hot water quantity of a plurality of water supplies of the hot fluid supply device or the stored hot water quantity of the volume type water heater or the gas quantity of the natural gas water heater is too small) is less than L2, the heating device heats and supplements the hot water. In this example, it is preferable that L1 be 1.2L/min, T2 be 1.5 sec, and L2 be 1.5L/min.

In this embodiment, the condition 2 is determined by whether the current flow rate is less than L2, the condition 2 is satisfied when the current flow rate is less than L2, the condition 2 is not satisfied when the flow rate becomes equal to or greater than L2, and the condition 2 is restored to the satisfied state when the flow rate is restored to less than L2. The condition 2 is that the judgment is continuously carried out in the whole stage, the judgment result is continuously changed, and once the condition is changed, the judgment result is changed accordingly.

When the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2, the normally open contact K2 is opened/JR 2 controls the coil to be not conducted, and the normally closed contact JR2-2 is closed (the condition 2 is met). When the conditions 1, 9 and 2 are simultaneously met, the normally open contact JR1-1 is closed/the normally open contact JR5-1 is closed/the normally closed contact JR2-2 is closed/the JR10 controls the coil to be conducted, and the normally open contact JR10-1 is closed (gives a heating signal).

Example 3: referring to fig. 5, this embodiment is similar to embodiment 1 except that: the control device also comprises a flow monitoring component, the mode gear is switched to a summer mode, the control device controls the heating device to heat when the conditions 1 and 9 'are met, and the control device controls the heating device not to heat when the conditions 1 or 9' are not met; wherein condition 1 is that the flow monitoring component monitors that the current flow rate at the first fluid inlet end of the control device is equal to or greater than L1, and condition 9' is that the flow monitoring component monitors that the flow rate at the first fluid inlet end of the control device undergoes a continuous change from equal to or greater than L1 to less than L1 within the time T2 and then the current flow rate is equal to or greater than L1. In the scheme, the limitation is that the flow of the first fluid inlet end of the valve device is limited to be larger than or equal to L1 when the operating mechanism of the valve device is operated, and the flow of the first fluid inlet end of the control device is heated when the flow is larger than or equal to L1, so that the reason for limiting is to avoid the false start of the heating device (when some water using components have fluid leakage or a water tap is not closed tightly or a water supply network has abnormal conditions or a user adjusts the water tap to be fine water flow so as to be beneficial to the survival of fishes in the water tank and the like), and the heating device can be provided with the minimum start flow (the heating device can be heated under the appropriate working condition). Meanwhile, in condition 9', in comparison with the winter mode, the summer mode is opposite to the winter mode, and only the operating mechanism of the valve device is operated to enable the valve device to open the first fluid inlet end and enable the flow rate to be larger than zero (namely, the operation of opening the faucet to discharge cold water in daily life), the heating device does not heat but directly discharges cold water, and when the faucet is opened to obtain hot water, the operating mechanism is operated to perform special actions (increase-decrease-increase, and in extreme cases, on-off-on) to obtain hot water, so that the requirement in summer is met (the summer water generally prefers to directly use cold water). In addition, since the operation manner of the daily habit (i.e. the operation of opening the faucet to discharge cold water) is to obtain cold water in the summer mode, when the user wants to use hot water after obtaining cold water and feels that the temperature of the water is low, the user only needs to operate the operation mechanism to perform special actions (turning up and turning down, and in an extreme case, turning off and turning on) to obtain hot water. In this embodiment, L1 is preferably 1.2 liters/minute and T2 is preferably 2 seconds.

In this embodiment, the judgment point of the condition 9 'is the starting point of the phase, that is, whether the condition 9' is satisfied is judged at the starting point of the phase, and the judgment result is continuously valid in the whole phase.

When the condition 1 and the condition 9' are not met simultaneously, the normally open contact JR1-1 is closed/the normally closed contact JR5-2 is opened/JR 10 controls the coil to be not conducted, and the normally open contact JR10-1 is opened (no heating signal is given).

Under the normal condition (the faucet is turned on after T2 time since the previous water is turned off), when the faucet is turned on, the faucet is turned down (in an extreme case, the faucet is turned off) within T2 time and then the faucet is turned on again, when the flow monitoring component monitors that the flow at the first fluid inlet end of the control device undergoes a continuous change process from the flow being greater than or equal to L1 to the flow being less than L1 within T2 time and then the current flow being greater than or equal to L1, the JS2 control coil gets an electric conduction change process again after the power is lost within T2 time, the slow suction normally open contact JS2-1 (the slow closure is instantly opened) is still kept in a delayed closure state within T2 and is continuously in an open state/JR 5 control coil is not conducted, and the normally closed contact JR5-2 is closed (condition 9') is met).

Example 4: referring to fig. 7, this embodiment is similar to embodiment 3 except that: the control device is provided with a second fluid inlet end which is a hot fluid inlet end, a second fluid outlet end which is a hot fluid outlet end, the second fluid outlet end is communicated with the second fluid inlet end of the valve device, and the control device controls the heating device to heat when all conditions 1, 9 'and 2 are met, and controls the heating device not to heat when any condition 1, 9' or 2 is not met; wherein condition 2 is that the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2. In this solution, the second fluid inlet end of the control device is externally connected to a thermal fluid supply device, for example, various water heaters, such as a gas water heater, a natural gas water heater, an electric water heater, a solar water heater, and an air energy water heater. Therefore, when the water heater is used for obtaining high-flow hot water, the heating device is closed; in addition, when the hot water quantity of the external hot fluid supply device is insufficient (for example, the hot water quantity of a plurality of water supplies of the hot fluid supply device or the stored hot water quantity of the volume type water heater or the gas quantity of the natural gas water heater is too small) is less than L2, the heating device heats and supplements the hot water.

Fig. 8 is a circuit diagram of embodiment 4, which is similar to the circuit diagram of embodiment 3, except that K2 and JR2 are added to the circuit diagram, K2 is a normally open contact of a flow rate monitoring member (a clarinet magnetic type water flow switch) provided at the second fluid inlet end of the control device, and JR2 is an intermediate relay.

When the flow monitoring component monitors that the current flow at the second fluid inlet end of the control device is less than L2, the normally open contact K2 is opened/JR 2 controls the coil to be not conducted, and the normally closed contact JR2-2 is closed (the condition 2 is met).

Example 5: referring to fig. 9, this embodiment is similar to embodiment 1 except that: the control device also comprises a flow monitoring component, the mode gear is switched to a four-season mode A, the control device controls the heating device to heat when the conditions 1, 5 and 6 are met, and the control device controls the heating device not to heat when any one of the conditions 1, 5 or 6 is not met; wherein, the condition 1 is that the current flow rate monitored by the flow monitoring component at the first fluid inlet end of the control device is greater than or equal to L1, the condition 5 is that the duration of the first fluid inlet end of the control device monitored by the flow monitoring component in the state that the current flow rate is greater than or equal to L1 is greater than or equal to T1, and the condition 6 is that the current flow rate monitored by the flow monitoring component at the first fluid inlet end of the control device in the state that the current flow rate is greater than or equal to L1 to time T1 is less than L3. In the scheme, the limitation is performed when the flow of the first fluid inlet end of the valve device is enabled to be larger than or equal to L1 by operating an operating mechanism of the valve device, and the flow of the first fluid inlet end of the control device is heated when the flow of the first fluid inlet end of the valve device is larger than or equal to L1, so that the limitation is performed because the heating device can be prevented from being started by mistake (when certain water using components have fluid leakage or a water tap is not closed tightly or a water supply network has abnormal conditions or a user adjusts the water tap to be fine water flow so as to be beneficial to the survival of fishes in the water tank and the like), and the heating device can be provided with the. In addition, an operating mechanism of the valve device is operated to adjust the flow of the first fluid inlet end of the valve device to a flow suitable for the water demand at the moment (namely, daily faucet opening and appropriate flow adjustment are carried out) usually, a period of time is required, the current flow at the time of T1 is taken as a judgment standard, namely, the current flow at the time of T1 is smaller than L3 for heating, the current flow at the time of T1 is larger than or equal to L3 for not heating, and the valve device accords with daily use habits (cold water is usually expected to be large flow, hot water is usually small flow), meanwhile, the heating temperature of the heating device is limited by heating power at large flow, the use experience is not good, and the heating is ensured only by limiting small flow; for this reason, when the flow monitoring part monitors that the first fluid inlet end of the control device keeps the current flow rate being equal to or more than L1 for a time period being equal to or more than T1, the heating is not carried out before the time period, so that the heating device is prevented from being started inefficiently (started and stopped immediately) and energy is saved. In particular, if the current flow rate is equal to or greater than L3 at T1 without heating (condition 6 selects no heating), the non-heating state continues to the end of the state where the first fluid inlet end of the valve device continuously maintains the current flow rate equal to or greater than L1, after which (after the time point of T1) no heating occurs even if the current flow rate at the first fluid inlet end is less than L3, i.e., cold water with different flow rates can be obtained at will during this period; if the current flow rate is less than L3 heating at T1 (condition 6 selects heating), the heating status continues to the end of the condition that the first fluid inlet end of the valve device continuously maintains the current flow rate equal to or greater than L1, and then (after the time point of T1) the first fluid inlet end is heated even if the current flow rate is equal to or greater than L3, i.e. hot water with different flow rates can be obtained at will during the time period. In this example, it is preferable that L1 be 1.2L/min, T1 be 1.6 seconds, and L3 be 4.5L/min.

In the present embodiment, the condition 5 is determined in such a manner that the condition 5 is not satisfied from the start of the stage to the time T1, and the condition 5 is satisfied at and after the time T1 and the satisfied state is maintained until the end of the stage. The condition 6 determination point is the time T1, that is, the time T1 is the time when the condition 6 is satisfied, and the state of being satisfied or not is maintained until the end of the stage. In the four season a mode, the condition 6 determination point is the T1 th time point, and the control device controls the heating device not to heat up from the beginning of the period to the T1 th time point because the condition 5 is in the unsatisfied state, that is, all the conditions (any one of the conditions is not satisfied) are not satisfied at the same time, and the condition 5 and the condition 6 are used at the same time in the four season a mode and cannot be used alone.

In addition, the heating is performed when the flow rate at the first fluid inlet end of the valve device is limited to be less than L3 by operating the operating mechanism of the valve device, and the flow rate at the first fluid inlet end of the control device is less than L3, so that the daily use habit is met (the cold water is generally expected to be a large flow rate, and the hot water is generally a small flow rate); meanwhile, under the condition of large flow, the heating temperature is difficult to guarantee due to the fact that the heating device is limited by heating power, the use experience is poor, and the small flow is limited to heat so as to ensure the use experience. In this example, it is preferable that L1 be 1.2L/min and L3 be 4.5L/min.

Therefore, when the water heater is used for obtaining high-flow hot water, the heating device is closed; in addition, when the hot water quantity of the external hot fluid supply device is insufficient (for example, the hot water quantity of a plurality of water supplies of the hot fluid supply device or the stored hot water quantity of the volume type water heater or the gas quantity of the natural gas water heater is too small) is less than L2, the heating device heats and supplements the hot water. In this example, it is preferable that L1 be 1.2L/min, L3 be 3.5L/min, and L2 be 1.5L/min.

The heating device related to the control of the control device is an instant heating type small kitchen appliance, the mode is applicable to a winter mode, a summer mode, a four-season A mode and a four-season B mode, and specific details are explained with reference to related embodiments and are not repeated.

Example 12: referring to fig. 22, a circuit diagram of the control device in this embodiment is similar to that of embodiment 2, except that the heating device is an instant-heating type small kitchen appliance, and the control device is integrated into the instant-heating type small kitchen appliance to form an integrated device, the integrated device is heated when the control device of the integrated device provides a heating signal (the normally open contact JR10-1 is closed) and the instant-heating type small kitchen appliance of the integrated device self-checks normally and meets the starting condition of the instant-heating type small kitchen appliance, and the integrated device is not heated when the control device of the integrated device does not provide a heating signal (the normally open contact JR10-1 is open). The self-test of the integrated device tankless small chef usually comprises: fluid temperature, heating body temperature, fluid pressure, resistivity of a water supply source and the like, and the starting conditions of the instant heating type small kitchen treasure generally comprise minimum starting flow and the like.

Typically, the valve assembly is exposed outside of its mounting platform, and the heating and control devices are concealed beneath the mounting platform. In this embodiment, the valve assembly (single handle, twin, hot and cold faucet) is exposed outside of its mounting platform, and the integrated device assembly (control and heating devices) is hidden below the mounting platform.

In this embodiment, the integrated device has two fluid outlet ends and two fluid inlet ends, and the first fluid outlet end is a cold fluid outlet end and is communicated with the first fluid inlet end of the faucet, the first fluid inlet end of the integrated device is a cold fluid inlet end and is communicated with the cold water inlet end, the second fluid outlet end of the integrated device is a hot fluid outlet end and is communicated with the second fluid inlet end of the faucet, and the second fluid inlet end of the integrated device is a hot fluid inlet end and is communicated with the hot water inlet end. At this time, the initial cold fluid sequentially passes through a first fluid inlet end and a first fluid outlet end of the integrated device, namely a first fluid inlet end and a first fluid outlet end of a valve device (water faucet), wherein the initial cold fluid has to pass through a control device and a heating device of the integrated device (can be heated when passing through the heating device) when passing through the first fluid inlet end and the first fluid outlet end of the integrated device; at this time, the second fluid inlet end of the integrated device is a hot fluid inlet end, the second fluid outlet end of the integrated device is a hot fluid outlet end, and the hot fluid sequentially flows through the second fluid inlet end and the second fluid outlet end of the integrated device, namely the second fluid inlet end and the fluid outlet end of the valve device (faucet), wherein the hot fluid needs to flow through the control device of the integrated device when flowing through the second fluid inlet end and the second fluid outlet end of the integrated device.

In this embodiment, the operating mechanism of the valve device (faucet) controls the flow change at the first fluid inlet end, the flow at the first fluid inlet end of the integrated device changes accordingly, and the control device of the integrated device senses the flow change at the first fluid inlet end of the integrated device and correspondingly controls the heating device of the integrated device accordingly. For example, an operating movement A of the operating mechanism of the valve device triggers the control device of the integrated device to control the heating device of the integrated device to heat, an operating movement B of the operating mechanism of the valve device triggers the control device of the integrated device to control the heating device of the integrated device not to heat, an operating movement C of the operating mechanism of the valve device triggers the control device of the integrated device to control the heating device of the integrated device to increase the heating power, an operating movement C' of the operating mechanism of the valve device triggers the control device of the integrated device to control the heating device of the integrated device to decrease the heating power, and so on.

When the conditions 1, 9 and 2 are simultaneously met, the normally open contact JR1-1 is closed/the normally open contact JR5-1 is closed/the normally closed contact JR2-2 is closed/the JR10 controls the coil to be conducted, and the normally open contact JR10-1 is closed (gives a heating signal).

In this embodiment, the pulse hall water flow sensor may be selected and disposed at the first fluid inlet end and the second fluid inlet end of the integrated device (or the split control device) integrated with the control device as the flow monitoring components (the pulse hall water flow sensor may convert the pulse signal into the switching value signal after being processed by the conversion circuit, and may output the on or off action signal when monitoring the set flow value). For example: when the flow value detected by a pulse Hall water flow sensor at a first fluid inlet end of an integrated device (or a split control device) integrated with the control device is greater than or equal to L1, the pulse Hall water flow sensor outputs a signal to close K1, and when the flow value detected by the pulse Hall water flow sensor is less than L1, the pulse Hall water flow sensor is opened K1; when the flow value is detected to be greater than or equal to L2, the pulse type Hall water flow sensor at the second fluid inlet end of the integrated device (or the split control device) integrated with the control device outputs a signal to close the K2, and when the flow value is detected to be less than L2, the K2 is opened. The preferred parameter point values in this embodiment may be modified to be 0.2 liters/minute for L1, 1 second for T2, and 0.25 liters/minute for L2. The integrated control device (or split control device) which changes the parameter point value has more sensitive control and the operation mode of the valve device can be more rapid. In addition, the pulse signals (the water flow is larger than the pulse signals output in a unit time, the number of the pulse signals output in a unit time is larger, and the water flow is smaller) output by the pulse type hall water flow rate sensors at the first fluid inlet end and the second fluid inlet end of the integrated device (or the separate control device) integrated with the control device may be input to the PLC or the single chip microcomputer programmed according to the setting conditions of the present embodiment, the preferred parameter point values (L1, T2, and L2) may be set in the PLC or the single chip microcomputer, and the heating signal or the non-heating signal may be output from the output port of the PLC or the single chip microcomputer.

In this embodiment, without being limited to the operation manner in embodiment 2, the control device of the integrated device may be triggered to control the heating device by the operation of the operating mechanism (cold/hot control lever) on the cold/hot water tap in the manner of the aforementioned embodiments 1 to 9 with reference to the above embodiments. Thus, through different condition control, whether heating or not can be controlled at will to directly obtain cold fluid/cold water or heated hot fluid/hot water.

The operating mechanism of the valve device comprises a conventional operating mechanism, such as a control handle of a faucet, but since the flow rate of the first fluid inlet port is also varied by operating the components of the faucet, such as the spout, the bubbler and the flow restrictor, at the outlet of the faucet, the operating mechanism of the valve device also comprises the components of the faucet, such as the spout, the bubbler and the flow restrictor, at the outlet of the faucet. That is, the operation mechanism of the valve device controls the flow change of the first fluid inlet end, and also includes components such as a water outlet nozzle, a bubbler and a flow restrictor at the water outlet of the valve device such as a faucet, and the flow change of the first fluid inlet end is controlled by adjusting or switching the components. In this embodiment, the valve device is an independent and integral faucet (single-handle dual-connection cold and hot faucet), and the operation mode of operating the valve by using the operating mechanism of the existing valve to control the flow change of the first fluid inlet end further includes: the flow variation of the first fluid inlet end of the faucet is controlled by operating the components (nozzle, bubbler and flow restrictor, etc.) at the outlet of the faucet and adjusting or switching these components. For example: the water outlet of the tap is provided with a water outlet nozzle (a shower water outlet mode and a bubbling water outlet mode) with two water outlet modes, the fluid flow is normally changed by switching the two modes, and the flow change of the first fluid inlet end can be controlled by operating a mode switching button on the water outlet nozzle.

In this embodiment, the control system of the integrated device may combine the control unit of the control device and the control unit of the instant heating type small kitchen appliance. For example: if the instant-heating type small kitchen appliance starting condition only has a fluid flow requirement, the instant-heating type small kitchen appliance starting condition can be combined into the control device, and the combination of the instant-heating type small kitchen appliance starting condition and the control device not only can simplify a control circuit, but also can share monitoring components (a flow switch or a flow sensor and the like); if the integrated device adopts a singlechip or a PLC control system, monitoring signals (flow, time and the like) in the control device and related signals (temperature, pressure, flow, water resistivity and the like) in the instant heating type small kitchen appliance can be controlled by programming; if the pulse output Hall flow sensor is adopted to monitor the flow (the first fluid inlet end of the integrated device and the second fluid inlet end of the integrated device), the flow signals required by the acquisition control device and the instant small kitchen appliance are monitored at the same time, and then the flow signals are input into a single chip microcomputer or a PLC for processing.

When the conditions 1, 3 and 5 are simultaneously met, the normally open contact JR1-1 is closed/the normally closed contact JR3-2 is closed/the normally open contact JS1-1 is closed/JR 10 is controlled to be conducted, and the normally open contact JR10-1 is closed (a heating signal is given).

In this embodiment, the control device of the integrated device is triggered to control the heating device by operation of the operating mechanism (cold/hot control handle) on the cold/hot water faucet. Thus, when the sectional drawing type cold and hot water faucet opens cold water in the cold water pipe, whether heating is carried out or not can be controlled freely to directly obtain cold fluid/cold water or heated hot fluid/hot water; when the hot water in the hot water pipe is started, whether the hot water is heated or not can be controlled in a careful manner so as to supplement the heat to the front section cold water in the hot water pipe and further reheat the hot water in the hot water pipe; reheating may or may not be performed with care when the mixing water is turned on.

In this embodiment, the heating means can be controlled by the control means of the triggering integrated means through the operation of the operating mechanism (cold/hot control lever) on the cold/hot water tap without being limited by the operation manner in embodiment 9. Thus, when the sectional drawing type hot and cold water faucet (including the sectional hot and cold water faucet) opens the cold water in the cold water pipe, it is possible to control whether to heat or not to directly obtain cold fluid/cold water or heated hot fluid/hot water through various condition controls in the manner of the foregoing embodiments 1 to 9; when the hot water in the hot water pipe is started, whether the hot water is heated or not can be controlled in a careful manner so as to supplement the heat to the front section cold water in the hot water pipe and further reheat the hot water in the hot water pipe; reheating may or may not be performed with care when the mixing water is turned on.

In this embodiment, the integrated device integrates the control device and the heating device, wherein the heating device is an instant-heating type small kitchen appliance, but other similar heating devices can be adopted, or a heating element with only a heating function is adopted, and the heating or non-heating is controlled by the control device. Common heating elements include stainless steel heating tubes, thick film heating tubes, cast aluminum heaters, heating wires, and the like.

Example 14: referring to fig. 24, this embodiment is similar to embodiment 5 except that: an additional condition 61 is added; the additional condition 61 is that when the flow monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from greater than or equal to L1 to less than L1, the satisfied state or the unsatisfied state continues for the duration T5 if the condition 6 at the previous stage is in the satisfied state or the unsatisfied state, and when the flow monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from less than L1 to greater than or equal to L1 in the duration T5, the condition 6 still continues to be in the satisfied state or the unsatisfied state. In this embodiment, when the flow monitoring unit monitors that the flow rate at the first fluid inlet of the control device changes from greater than or equal to L1 to less than L1, if the condition 6 at the previous stage is in a satisfied state or an unsatisfied state, the satisfied state or the unsatisfied state continues for the duration T5, and if the flow rate monitoring unit monitors that the flow rate at the first fluid inlet of the control device changes from less than L1 to greater than or equal to L1 in the duration T5, the condition 6 still continues to be in a satisfied state or an unsatisfied state, on one hand, when the tap water supply is in an abnormal state or there is an abnormal condition such as bubble flow in the tap water pipe network, the flow rate fluctuation of the fluid in the tap water pipe network may occur for a short time, on the other hand, when the user operates the operation mechanism of the valve device to adjust the flow rate at the first fluid inlet (i.e., when the tap handle is operated to adjust the flow rate in daily life Short-time flow fluctuations that may cause the satisfied state of the condition 6 to change (e.g., the condition 6 changes from the satisfied state to the unsatisfied state or the condition 6 changes from the unsatisfied state to the satisfied state), and the additional condition 61 is added to avoid the similar situation. In this example, it is preferable that L1 be 1.2L/min, T1 be 1.6 sec, L3 be 4.5L/min, and T5 be 0.9 sec.

In this embodiment, since the additional condition 61 is added, whether the condition 6 is in the satisfied state or the unsatisfied state needs to depend on more factors, which is more suitable for the actual situation faced in daily life, as an example: as an example, when the conditions 1 and 6 are satisfied simultaneously, the control device outputs the heating signal, and when the flow rate of the fluid in the tap water network fluctuates for a short time (usually within the time T5), the flow rate monitoring unit monitors that the flow rate at the first fluid inlet end of the control device fluctuates less than L1 for a short time (within the time T5) (the flow rate is from equal to or greater than L1 to less than L1 and then returns to equal to or greater than L1). Before (last stage) the condition 6 is in a state of satisfaction, after (this stage) the fluctuation process the condition 6 is still in a state of satisfaction (according to the additional condition 61), the condition 6 is not changed due to a short time flow fluctuation of the fluid in the mains network, and the control means outputs the heating signal both before (last stage) and after (this stage) the flow fluctuation. Second, when the conditions 1 and 6 are met, the control device outputs the heating signal, a user may have a flow fluctuation for a short time (for example, during time T5) when the user operates the operating mechanism of the valve device to adjust the flow of the first fluid inlet end (i.e., the faucet handle is operated to adjust the water flow in daily life) during the hot water use, and the flow monitoring component monitors that the flow of the first fluid inlet end of the control device has a fluctuation process smaller than L1 (the flow is from equal to or greater than L1 to less than L1 and then returns to equal to or greater than L1) during the short time (during time T5). Before the fluctuation process (the previous stage), the condition 6 is in the satisfied state, after the fluctuation process (the stage), the condition 6 is still in the satisfied state (according to the additional condition 91), the condition 6 is not changed due to the flow fluctuation occurring for a short time, the control device outputs heating signals before the flow fluctuation (the previous stage) and after the flow fluctuation (the stage), and the user continues to obtain hot water. In the third example, when the condition 1 is satisfied but the condition 6 is not satisfied, the control device outputs no-heating signal, and at this time, if the flow rate of the fluid in the tap water network fluctuates for a short time (usually within the time T5), the flow rate monitoring unit monitors that the flow rate at the first fluid inlet end of the control device fluctuates for a short time (within the time T5) and is less than L1 (the flow rate is from equal to or greater than L1 to less than L1 and then returns to equal to or greater than L1). Before the fluctuation process (the previous stage), the condition 6 is in the unsatisfied state, after the fluctuation process (the stage), the condition 6 is still in the unsatisfied state (according to the additional condition 61), the condition 6 is not changed due to the transient flow fluctuation of the fluid in the water supply network, and the control device outputs the no-heating signal before the flow fluctuation (the previous stage) and after the flow fluctuation (the stage). Fourth, when the condition 1 is satisfied but the condition 6 is not satisfied, the control device outputs no-heating signal, a user may have a flow fluctuation for a short time (for example, within a time period of T5) when the user operates the operating mechanism of the valve device to adjust the flow of the first fluid inlet port during the cold water use (i.e., the faucet handle is operated to adjust the water flow in daily life), and the flow monitoring part monitors that the flow of the first fluid inlet port of the control device has a fluctuation process smaller than L1 (the flow is from equal to or greater than L1 to less than L1 and then returns to equal to or greater than L1) for a short time (within a time period of T5). Before the fluctuation process (the previous stage), the condition 6 is in the unsatisfied state, after the fluctuation process (the stage), the condition 6 is still in the unsatisfied state (according to the additional condition 61), the condition 6 is not changed due to the flow fluctuation for a short time, the control device outputs a non-heating signal before the flow fluctuation (the previous stage) and after the flow fluctuation (the stage), and the user continues to obtain cold water.

In the present embodiment, the condition 5 is determined in such a manner that the condition 5 is not satisfied from the start of the stage to the time T1, and the condition 5 is satisfied at and after the time T1 and the satisfied state is maintained until the end of the stage. The condition 6 determination point is the time T1, that is, the time T1 is the time when the condition 6 is satisfied, and the state of being satisfied or not is maintained until the end of the stage. In the four season a mode, the condition 6 determination point is the T1 th time point, and the control device controls the heating device not to heat up from the beginning of the period to the T1 th time point because the condition 5 is in the unsatisfied state, that is, all the conditions (any one of the conditions is not satisfied) are not satisfied at the same time, and the condition 5 and the condition 6 are used at the same time in the four season a mode and cannot be used alone.

In this embodiment, since the additional condition 61 is added, the determination point of whether the condition 6 is satisfied may occur at two different times, specifically: if the additional condition 6 holds (the interval between the end of the previous stage and the start of this stage is within T5) at the start of this stage the condition 6 is still in the satisfied state or the unsatisfied state continued from the previous stage, the judgment point is the starting point of the stage, and if the additional condition 6 is not satisfied (the interval between the end of the previous stage and the start of the stage is not within T5), at the time T1 of the stage, however, since the condition 5 is not satisfied from the start of the phase to the T1, regardless of whether the determination point of the condition 6 is at the start point of the phase or at the T1 of the phase, the control device controls the heating device not to heat from the start of the phase to the T1, i.e. the actual effect of the control means controlling the heating means is not different, although the decision point whether condition 6 is fulfilled or not may occur at two different moments in time.

Fig. 25 is a circuit diagram of example 14, which is similar to that of example 5, except that a slow release relay (power-off delay) JS5 is added to the circuit diagram, and the release time is T5.

When the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is greater than or equal to L1, the normally open contact K1 is closed/JR 1 control coil is conducted, and the normally open contact JR1-1 is closed (condition 1 is met)/JS 1 control coil is conducted/JS 5 control coil is conducted; when the flow monitoring part monitors that the duration of the state that the first fluid inlet end of the control device keeps the current flow rate to be greater than or equal to L1 is greater than or equal to T1, closing a slow suction (power-on delay) normally open contact JS1-1 (condition 5 is met); when the flow monitoring part monitors that the current flow at the first fluid inlet end of the control device is kept in a state that the current flow is greater than or equal to L1 until the time T1 is less than L3, the normally open contact K3 is opened/the JR3 control coil is not conducted, at the moment, the normally open contact JR1-1 on one circuit is closed/slowly sucked to form the normally open contact JS1-1 on/normally closed contact JR3-2 on/normally closed contact JR9-2 on/JR 8 control coil is conducted (and a self-locking circuit consisting of JS5-1, JR8-1 and JR8 control coil is formed until the slow-release power-off delay normally open contact JS5-1 is disconnected), the normally open contact JR3-1 on/JR 9 control coil on the other circuit is not conducted (and forms an interlocking circuit with the intermediate relay JR8, namely JR8 control coil conducting/normally closed contact JR8-2 disconnecting/JR 9 control coil is not conducted), normally open contact JR8-1 closed/normally closed contact JR9-2 closed (condition 6 is satisfied). When the conditions 1 and 5 and the regulation 6 are simultaneously met, the normally open contact JR1-1 is closed/slowly absorbs the normally open contact JS1-1, the normally open contact JR8-1, the normally closed contact JR9-2 and the normally closed contact JR10 control the coil to be conducted, and the normally open contact JR10-1 is closed (a heating signal is given).

In the embodiment, when the flow monitoring component monitors that the current flow at the first fluid inlet end of the control device is greater than or equal to L1 until the current flow at the time T1 is greater than or equal to L3, the normally open contact K3 is closed/JR 3 control coil is turned on, at this time, the normally open contact JR1-1 on one circuit is closed/slowly sucks the normally open contact JS1-1 to close/normally open contact JR3-1 to close/normally closed contact JR8-2 to close/JR 9 control coil is turned on (and the JS5-1, JR9-1 and JR9 control coil form an auto-lock type circuit until the normally open contact JS5-1 is turned off during slow-release power failure delay), the normally closed contact JR3-2 on/JR 8 control coil is turned off on the other circuit (and JR9 form an interlocking type circuit, namely JR9 control coil on/JR 9-2 open/JR 362 control coil is turned off/JR 8, normally open contact JR8-1 open/normally closed contact JR9-2 open (condition 6 not satisfied).

In the present embodiment, the additional condition 61 is that when the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from equal to or greater than L1 to equal to or less than L1, if the condition 6 at the previous stage is in the satisfied state or the unsatisfied state, the satisfied state or the unsatisfied state continues for the duration T5, and if the flow rate monitoring part monitors that the flow rate at the first fluid inlet end of the control device changes from equal to or less than L1 to equal to or greater than L1 within the duration T5, the condition 6 still continues to be in the satisfied state or the unsatisfied state. In a circuit diagram, when a flow monitoring component monitors that the flow at a first fluid inlet end of a control device is from greater than or equal to L1 to less than L1, if a previous (last stage) condition 6 is in a satisfied state, a JR8 control coil conduction/JS 5 control coil conduction/normally open contact JR8-1 closing/slow-release normally open contact JS5-1 closing, when a normally open contact K1 is opened/JR 1 control coil power-off/normally open contact JR1-1 opening/JS 5 coil power-off/slow-release normally open contact JS5-1 starts power-off delay, during the power-off delay (T5) the normally open contact JS5-1 is in a closed state/JR 8 control coil conduction/normally open contact JR8-1 closing/normally closed contact JR9-2 closing (the condition 6 is in a satisfied state, and the duration time T5 is continued; when the flow monitoring component monitors that the flow at the first fluid inlet end of the control device is from less than L1 to greater than or equal to L1 (the phase starts) within the duration T5, the normally open contact K1 is closed/JR 1 controls the coil conduction/normally open contact JR1-1 to be closed (the condition 1 is met)/JS 5 controls the coil conduction/slow-release normally open contact JS5-1 to be closed (the power-off delay is terminated and the closed state is continued)/JR 8 controls the coil conduction/normally open contact JR8-1 to be closed/the normally closed contact JR9-2 to be closed/(the condition 6 is met), and the condition 6 is still continued to be in the satisfied state; if the condition 6 is in an unsatisfied state before (at the last stage), controlling the coil conduction/JS 5 to control the coil conduction/normally open contact JR9-1 to be closed/slow-release normally open contact JS5-1 to be closed by JR9, when the normally open contact K1 is opened/JR 1 to control the coil power-off/normally open contact JR1-1 to be opened/JS 5 to control the coil power-off/slow-release normally open contact JS5-1 to start power-off delay, controlling the coil conduction/normally open contact JR8-1 to be opened/normally closed contact JR9-2 to be opened by JR9 during the power-off delay (T5) (the condition 6 is in an unsatisfied state and then continuing for time T5); when the flow monitoring component monitors that the flow at the first fluid inlet end of the control device is from less than L1 to equal to or more than L1 within the duration T5 (the phase begins), the normally-open contact K1 is closed/JR 1 controls the coil conduction/normally-open contact JR1-1 to be closed (the condition 1 is met)/JS 5 controls the coil conduction/slow-release normally-open contact JS5-1 to be closed (the power-off delay is terminated and the closed state is continued)/JR 9 controls the coil conduction/normally-open contact JR8-1 to be disconnected/the normally-closed contact JR9-2 to be disconnected/(the condition 6 is not met), and the condition 6 is still continued to be in the unsatisf.
