Calcium ions, magnesium ions, and the like are generally present in water. The carbon dioxide in the air will also be dissolved in water to a small extent.

Detailed Description

To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The water heater is commonly used in families, and can heat cold water in a short time. The heated water can be used for washing and rinsing, and is very convenient. However, insoluble matter is generated during the heating with cold water. The newly generated insoluble substances and impurities in water can jointly form scale, and the scale is deposited at the bottom of a water tank in the water heater or flows out of a water outlet pipe of the water heater along with water used by a user. The scale flowing out along with the water can be blocked in the water outlet pipe and the shower head, so that the inconvenience of water use is caused. Therefore, scale in the water heater needs to be cleaned in time. However, the user is not aware of the deposition of scale inside the water heater and cannot determine when the water heater needs to be cleaned.

In the implementation of the present application, the inventors found that the amount of scale formation is related to the volume of water heated. The scale generation amount can be inferred according to the volume of the heated water, so that the water heater can remind the pollution discharge after a certain amount of scale is generated.

Fig. 1 is a schematic view of an application scenario provided in the present application. A water heater 101 is installed indoors, and a button for controlling heating is arranged on the water heater 101. The user can turn on the heating function by pressing a key. The keys on the water heater 101 can be mechanical keys to control the power on and off of the water heater 101. The on/off of the heating function may also be controlled for a virtual touch button on the display device of the water heater 101. These are merely two examples and are not intended to be limiting. Simultaneously with the heating function being turned on, the water heater 101 begins to count the heating volume. Scale begins to form during the heating process. After multiple heating, the water heater 101 determines that the counted heating volume has met the preset condition, and then sends a prompt to prompt the user that the pollution discharge is currently required. Specific implementations are described below by way of examples.

Fig. 2 is a flowchart of an emission control method according to an embodiment of the present disclosure. As shown in fig. 2, the method of the present embodiment includes:

s201, acquiring the accumulated heating time and the water heating capacity of the water heater.

The water heater may be heated once for a period of time of about ten minutes to thirty minutes. The scale produced during each heating may be small and may not be sufficient to meet the conditions for disposal. If the sewage is discharged after each heating, water resources may be wasted.

Therefore, it may be necessary to accumulate the heating time periods of the water heater several times in succession, resulting in an accumulated heating time period. The time when the accumulated heating time length begins to accumulate is the time when the water heater begins to heat when used for the first time, or the time when the water heater begins to heat after the pollution discharge is finished every time. The cumulative heating time period in the present application refers to a heating time period that is cumulative from the time when the cumulative operation starts to the present time.

The term "water heating capacity" in the present application refers to the volume of water that can be heated per unit time by a water heater to heat water at a certain temperature to a target temperature. The heating water capacity may be a fixed value or may be a variable value.

S202, determining the accumulated heating volume according to the accumulated heating time length and the water heating capacity.

Similar to the concept of the accumulated heating time, the time when the accumulated heating volume starts to be accumulated is the time when the water heater starts to be heated when being used for the first time, or the time when the water heater starts to be heated after the pollution discharge is finished every time. The cumulative heating volume in the present application refers to a heating volume that is cumulative from the time when the cumulative is started to the present time.

And determining the accumulated heating volume after acquiring the accumulated heating time and the water heating capacity.

The determination of the cumulative heating volume may be a periodic statistic. For example, the heating volume in the past minute is determined every minute and is added to the cumulative heating volume one minute ago to obtain the current cumulative heating volume. For example, the heating volume in the current heating process is determined after each heating process is completed, and the heating volume is added to the cumulative heating volume before the current heating process to obtain the current cumulative heating volume.

And S203, if the accumulated heating volume meets the preset condition, outputting pollution discharge prompt information, wherein the pollution discharge prompt information is used for indicating that the water heater needs to discharge pollution currently.

The preset condition in this application is a condition indicating a threshold value of the cumulative heating volume required for the sewage discharge.

The cumulative heating volume has a certain correlation with the amount of scale formed and can be determined by experimental analysis. The formation of scale is also related to water quality, and the difference in water quality is generally regional. Thus, the relationship between the area and the amount of scale formation can be indirectly determined. When the preset condition is set, the preset condition can be set by considering various factors such as the area, the local water quality and the like.

The pollution discharge control method provided by the embodiment comprises the following steps: acquiring the accumulated heating time and the hot water making capacity of the water heater; determining the accumulated heating volume according to the accumulated heating time and the hot water producing capacity; and if the accumulated heating volume meets the preset condition, outputting pollution discharge prompt information, wherein the pollution discharge prompt information is used for indicating that the water heater needs to discharge pollution currently. Through confirming the accumulative heating volume of the water heater, after the accumulative heating volume meets the preset condition, the blowdown prompt message is output, and the blowdown is reminded, so that dirt in the water tank of the water heater can be discharged in time, and the water heater is prevented from being damaged.

In a preferred technical solution of the above pollution discharge control method, the preset condition may be specifically set to be that the accumulated heating volume is greater than or equal to a preset value. Correspondingly, if the accumulated heating volume meets the preset condition, the blowdown prompt message is output, and the method can include the following steps: and if the accumulated heating volume is larger than or equal to the preset value, outputting pollution discharge prompt information.

The preset condition may also be set such that the cumulative heating volume is greater than the preset value. Correspondingly, if the accumulated heating volume meets the preset condition, the blowdown prompt message is output, and the method can include the following steps: and if the accumulated heating volume is larger than the preset value, outputting pollution discharge prompt information.

The preset value in the present application may be a value automatically determined according to the water quality of the area or the local area. For example, a correspondence relationship between the area or water quality, the cumulative heating time, and the amount of scale produced is previously constructed based on experimental data or data collected by other means. The corresponding relation is directly stored (or stored in a database form) in a water heater which is the main execution body of the method or a server which is in communication connection with the water heater. The method comprises the steps of indirectly acquiring corresponding data of accumulated heating time and scale generation amount by acquiring information of a current region or water quality input by a user, and determining preset values.

The preset value can also be the acquired set value of the user. For example, the correspondence relationship can be marked in the use description of the water heater for reading and reference by the user. The user then sets a preset value on the water heater performing the method or through a terminal device that can communicate with the water heater.

After the water heater is used for a period of time, the user can also adjust the preset value according to the actual use condition, so that the water heater is more suitable for use habits.

The flexible arrangement mode can provide more choices for users, and determines more suitable pollution discharge frequency and pollution discharge conditions according to actual conditions.

In the preferable technical scheme of the pollution discharge control method, the outputting of the pollution discharge prompt information can be outputting of the pollution discharge prompt information by the main water heater executing the method so as to remind a user of pollution discharge. For example, a display interface on the water heater displays a text prompt message like "please open the drain pipe in time to drain". For example, similar voice prompt information such as 'please open the sewage pipe in time to discharge sewage' is output through the sound output device of the water heater. And prompting can be carried out in multiple prompting modes simultaneously.

The output of the pollution discharge prompt information can also be output by the water heater to terminal equipment such as a mobile phone in communication connection with the water heater, so that the terminal equipment reminds a user of pollution discharge. For example, a display interface on the terminal device displays a text prompt message such as "please open the drain pipe in time to drain". For example, similar voice prompt information such as "please open the sewage pipe in time to discharge sewage" is output through the sound output device of the terminal device. And prompting can be carried out in multiple prompting modes simultaneously.

The output of the pollution discharge prompt information can also be that the pollution discharge prompt information is output to a server in communication connection with the water heater through the water heater, so that the server forwards the pollution discharge prompt information to terminal equipment such as a mobile phone and the like to remind a user of discharging pollution. The specific reminding manner can refer to the manner of the above example.

Except the water heater reminding mode and the manual sewage discharging mode of the user, the water heater can also directly perform sewage discharging operation. For example, outputting the pollution discharge prompting information may further include: and sending pollution discharge prompt information to a driving device of the water heater so that the driving device controls a pollution discharge pipe of the water heater to be opened according to the pollution discharge prompt information to discharge pollution.

Similar to the above embodiment, the blowdown prompt message can be directly sent by the water heater, that is, after the accumulated heating volume is determined to meet the preset condition, the blowdown pipe is immediately controlled to be opened to carry out blowdown. The water heater can also send the pollution discharge prompt information to the terminal equipment directly or indirectly through the server, then the signal for indicating the determined pollution discharge and fed back after the user determines the pollution discharge is received, and the signal for determining the pollution discharge controls the opening of the pollution discharge pipe to discharge the pollution.

The mode of controlling the opening of the sewage draining pipe can be as above, a driving device is arranged at the water outlet of the sewage draining pipe, and the water outlet of the sewage draining pipe is driven to be opened by controlling the action of the driving device. The driving device can be a mechanical arm or a driving motor and the like arranged at the water outlet of the sewage draining pipe. This is merely an example and does not limit the specific structure.

After the blow-off pipe is opened, water flow can enter the water heater through the water inlet pipe and dirt is discharged from the blow-off pipe. This is related to the principle of water heaters. The water storage type water heater generally adopts a water jacking method to take hot water, and after a water outlet pipe is opened, cold water is forced to enter a water storage tank of the water heater from a water inlet pipe by water pressure. Similarly, after the blow-off pipe is opened, water in the water storage tank flows out of the blow-off pipe due to the pressure effect, and dirt at the bottom of the water storage tank of the water heater is taken away. Meanwhile, cold water enters the water storage tank of the water heater through the water inlet pipe under the action of pressure.

Meanwhile, the water inlet pipe is arranged at the bottom of the water storage tank, the water outlet direction of the water inlet pipe is vertical to the diameter direction of the water storage tank, and the water inlet of the sewage discharge pipe is arranged at the lowest point of the water level of the water storage tank. Therefore, in the normal use process, the water flow entering the water storage tank of the water heater through the water inlet pipe can form vortex at the bottom of the water storage tank, and impurities such as generated scale are gathered to the lowest point of the water level of the water storage tank. When the blow-off pipe is opened for blow-off, the water flow entering the water storage tank of the water heater from the water inlet pipe can form certain impact force on the dirt at the bottom of the water storage tank, so that the dirt is easier to discharge.

Fig. 3A is a schematic longitudinal structural diagram of a water heater provided by the present application, and fig. 3B is a schematic transverse structural diagram of a water heater provided by the present application. Referring to fig. 3A and 3B, it can be seen that the horizontal cross-section of the tank of the water heater is approximately circular. The water inlet pipe 301 is disposed at the bottom of the water storage tank of the water heater, and the water outlet direction of the water inlet pipe is as shown by the arrow in fig. 3B, and is perpendicular to the diameter direction of the water storage tank, i.e. parallel to the tangential direction of the water storage tank. The water inlet pipe 301 may be an elbow pipe with a certain angle as shown in fig. 3B, or may be other structures that can achieve the same water outlet effect, which is not limited herein.

The inlet 303 of the waste pipe 302 is arranged at the lowest point of the water level of the water storage tank, and the position is shown in figure 3A. The outlet of the waste pipe 302 can be set at any height, and the position shown is only one of the realization modes.

In a preferred embodiment of the above method for controlling pollution discharge, after outputting the pollution discharge prompting information, the method further includes: and after the pollution discharge is finished, resetting the accumulated heating time length.

According to the above description of the accumulated heating time, it can be known that the accumulation is restarted after each blowdown is finished. Therefore, after the end of the sewage discharge, the accumulated heating time needs to be cleared, and the accumulation is restarted for a new time.

Corresponding to the various pollution discharge reminding modes, the mode for determining the end of the pollution discharge can be various. The water heater outputs the pollution discharge prompt information to remind a user of discharging pollution, and then a pollution discharge ending instruction triggered by the user can be detected. For example, the user can trigger the blowdown ending instruction through a key arranged on the water heater, or input the voice-triggered blowdown ending instruction through a voice input device arranged on the water heater. For another example, the user may trigger the blowdown ending instruction through a key provided on the terminal device, or input a voice-triggered blowdown ending instruction through a voice input device provided on the terminal device. And then the terminal equipment directly forwards a blowdown ending instruction to the water heater, or indirectly forwards the blowdown ending instruction to the water heater through the server. For another example, the user may trigger a blowdown complete command by closing the blowdown pipe outlet. And after a pollution discharge finishing instruction triggered by a user is detected, clearing the accumulated heating time length by the water heater.

In addition, in the automatic pollution discharge mode of the water heater, a pollution discharge end condition can be set at the same time, and the end of the pollution discharge is determined after the pollution discharge end condition is met. For example, the blowdown time period may be set to one minute.

The above-mentioned capability of obtaining the heated water may be different according to the heating mode of the water heater. The heating modes which are commonly used are electric heating and air energy heating. In the electric heating mode, the electric energy is relatively stable, so the water heating capacity is generally a fixed value and can be directly obtained. The air energy heating means that the heat energy in the air is converted into the heat energy of the water by using an air energy conversion device, such as a heat pump. Therefore, in the mode that air can be heated, the water heating capacity has a certain relation with the ambient temperature.

Under the heating mode that air can heat, the acquisition mode of heating water ability can be: and acquiring the ambient temperature, and determining the water heating capacity according to the ambient temperature.

In one particular implementation, the water heating capacity may be determined in a look-up table. For example, the correlation between the ambient temperature and the water heating capacity can be determined according to historical data, and a corresponding relation table can be constructed. And after the environmental temperature is obtained, determining the corresponding hot water heating capacity by inquiring the relation table.

In another specific implementation, the heating water capacity may be determined in a formulaic calculation manner. For example, the relationship between the ambient temperature and the capacity to heat water may be determined from historical data. And after the ambient temperature is obtained, the corresponding water heating capacity is determined through the calculation of the relational expression. Through verification, one possible relationship is as follows:

Q＝a*T³+b*T²+c*T+d

wherein Q is the water heating capacity; t is the ambient temperature; a. b, c and d are constants, and values may be different according to different actual conditions.

In a preferred technical solution of the above-mentioned pollution discharge control method, if the accumulated heating volume satisfies a preset condition, a pollution discharge prompt message is output, including: and if the accumulated heating volume meets the preset condition, outputting pollution discharge prompt information after the water heater stops heating.

The water heater may still be in a heating state when the cumulative heating volume meets a preset condition. If the user is ready to use hot water at this time, the pollution discharge is directly started, which may cause the discharge of the heated water in the water heater, and the addition of cold water delays the water using time of the user. Therefore, preferably, the blowdown prompt message can be output after the water heater stops heating, so as to carry out blowdown.
