Referring to fig. 1, a flowchart of a method for controlling a cooking stove combination according to an embodiment of the present application is provided, including the following steps:

s10, collecting a temperature value obtained by a detection piece 220 on the cigarette making machine 200;

in the present embodiment, referring to fig. 5, the range combination kitchen ware includes a gas range 100, a range hood 200 and a control part. The gas range 100 includes a range body 110, a support 120 and a flame generating part 130, wherein the range body 110 has a range opening, the support 120 and the flame generating part 130 are both disposed at the range opening, the support 120 is used for supporting a pot, and the flame generating part 130 is used for generating a flame. The range hood 200 is disposed above the gas range 100, the range hood 200 includes a body 210 and a detecting member 220 disposed on the body 210, and the detecting member 220 is disposed toward the cooktop hole for acquiring a temperature at the cooktop hole. The control unit is in communication with the detecting member 220 and the flame generating unit 130.

In this step, the control unit collects the temperature value obtained by the detection unit 220 on the cigarette maker 200. The detecting element 220 is a non-contact temperature sensing element, such as an optical temperature sensing element, a radiation temperature sensing element, a colorimetric temperature sensing element, and the like. Preferably, the detecting member 220 includes an infrared sensing probe, and the infrared sensing probe is in communication with the control portion, which is configured to be disposed toward the cooktop for acquiring the temperature at the cooktop. The infrared sensing probe is adopted to detect the temperature of the cooking range, the temperature measurement technology is mature, the application range is wide, and the use cost is low.

S20, judging whether the bracket 120 on the gas stove 100 is in a pan or not according to the acquired temperature value;

alternatively, the control part may determine whether the pan sits on the bracket 120 by a magnitude relationship between the collected temperature value and a preset threshold value. For example, the control unit stores a first temperature threshold and a second temperature threshold, and the first temperature threshold is higher than the second temperature threshold. When the collected temperature value exceeds the first temperature threshold, it indicates that the temperature of the flame at the cooktop detected by the detecting element 220 is that the pot is not seated on the rack 120 at the cooktop, and then it is determined that the rack 120 is not seated on the pot. When the temperature value of gathering is less than second temperature threshold value, it is the temperature of eye of a kitchen range department pan to explain that detection piece 220 detects, that is to say, has placed the pan on the support 120 of eye of a kitchen range department, then judges that support 120 sits the pot. The above is merely a specific example of determining whether the rack 120 is seated according to the temperature value, and is not limited to the scheme.

S30, when the support 120 is not seated, controlling the flame generating part 130 on the gas range 100 to reduce or close the flame generated by itself.

Specifically, flame generation portion 130 includes admission valve, intake pipe and combustor, and intake pipe intercommunication combustor and air supply, admission valve locate the intake pipe and with control portion communication connection, the combustor is located eye of a kitchen range department and is used for producing flame. In the step, the controller adjusts the flow rate of the air inlet pipe by controlling the opening of the air inlet valve, so that the gas quantity participating in combustion is changed, and the purpose of changing the flame size is achieved. When the flame needs to be closed, the control part controls the air inlet valve to stop the air inlet pipe, the air source cannot reach the burner, and the flame is extinguished. When the flame needs to be reduced, the control part controls the opening of the air inlet valve to be reduced, the flow of the air source is reduced, and further the flame is reduced, at the moment, the gas stove 100 provides small fire, and the waste of the gas is reduced to a certain extent.

The inlet valve may be a solenoid valve. Generally, a burner includes a burner, a distributor, an ignition pin, a thermocouple, etc., and the burner is communicated with an intake pipe. For the assembling relationship of the burner, the distributor, the ignition needle, the thermocouple and other components, please refer to the structure of the existing burner, and the details and limitations are not repeated herein.

According to the control method of the smoke and kitchen combined kitchen ware, after the smoke machine 200 and the gas stove 100 are started, the flame generating part 130 in the gas stove 100 produces high-temperature flame at the stove hole. When the pan is not seated on the rack 120, the temperature detected by the detection part 220 is the flame temperature at the cooking range, and when the pan is seated on the rack 120, the temperature detected by the detection part 220 is the temperature of the pan. Because the temperature of flame is far greater than the temperature of pan, can judge whether to sit the pot on support 120 according to the temperature value that detection piece 220 detected. When the support 120 is not operated when sitting on the pot, the flame size of the flame generator is set by the user himself, and the user can cook normally. When the bracket 120 is not seated, the control part controls the flame generator to reduce or shut off the flame generated by itself.

Compared with the prior art, the temperature of the cooking range 100 at the cooking range is detected by the detection piece 220 on the range hood 200, whether the support 120 is used for cooking is judged according to the temperature value at the cooking range, and the flame generated by the flame generator is reduced or closed when the support 120 is not used for cooking, so that the combustion amount of fuel gas can be reduced when the support 120 is not used for cooking, the waste of fuel gas is reduced, and the utilization rate of fuel gas is improved. Meanwhile, the detection piece 220 is arranged on the range hood 200, the temperature of the detection piece 220 at the cooking range is measured in a non-contact manner by utilizing the position relation between the range hood 200 and the gas stove 100, the detection piece 220 is arranged without adding an additional supporting structure, the whole structure of the combined cooking utensil of the range hood is greatly simplified, the kitchen area occupied by the combined cooking utensil of the range hood is reduced, and the space utilization rate of a kitchen table top is improved. In addition, the range hood 200 is installed above the gas stove 100, and the detection piece 220 can be installed above the cooking hole, so that the detection piece 220 is easily arranged towards the cooking hole, and the detection accuracy of the detection piece 220 is improved.

The control part can be a singlechip, a CPU, a microprocessor and the like. In a preferred embodiment, the control part comprises a first controller and a second controller, the first controller is connected with the second controller in a communication way, the first controller is arranged on the range hood 200 and is connected with the detection piece 220 in a communication way, and the second controller is arranged on the gas stove 100 and is connected with the flame generation part 130 in a communication way. The first controller is used for collecting the temperature value obtained by the detection part 220 and judging whether the support 120 sits on the pot according to the collected temperature value, and the first controller informs the second controller to control the flame generation part 130 to reduce or close the flame generated by the first controller when the support 120 does not sit on the pot. At this time, the first controller is used for judging the pot setting condition of the support 120, the second controller is used for controlling and adjusting the flame size of the flame generator, the work division cooperative processing is carried out, and the judgment and execution are separately controlled, so that the control cost is reduced.

Please refer to fig. 2, which is a flowchart illustrating a method for controlling a range combination kitchen ware in another embodiment of the present application, and the difference between the method and the embodiment of fig. 1 is that step S20 includes S21 and S22, and step S30 includes S31 and S32, which are detailed as follows:

s21, when the temperature value meets a first condition, judging that the bracket 120 is in a long-term uncooked state;

s22, when the temperature value meets a second condition, judging that the bracket 120 is in a short-term uncooked pan state;

s31, when the support 120 is in a long-term uncooked state, controlling the flame generating part 130 to close the flame generated by itself;

and S32, when the support 120 is in the short-term uncooked state, controlling the flame generating part 130 to reduce the self-generated flame.

In the present embodiment, the rack 120 includes a long-term unsettled state and a short-term unsettled state.

The long-term non-pot-sitting state means that no pot is placed on the support 120 for a long period of time, which indicates that the user has finished cooking and forgot to turn off the fire or that the user has not placed a pot on the support 120 all the time after the user is on the fire, and the gas range 100 is in the idle-burning state all the time. The user need not cook subsequently, perhaps can not cook for a long time, continues to burn the gas this moment and can cause the waste in a large number of gas. Therefore, when it is determined that the holder 120 is not seated for a long time, the control unit controls the flame generation unit 130 to turn off the flame generated by itself, thereby completely extinguishing the flame and preventing the waste of gas and the occurrence of fire risk.

The short-term uncooked pot state is a state where no pot is placed on the rack 120 for a short period of time, which indicates that the rack 120 is away from the pot for a short time, for example, when a user removes the pot halfway through a cooking process to facilitate operations such as pouring out food, or removes the pot to avoid burning out, the pot is away for a short time. Because the user only removes the pan for a short time, in order to avoid the repeated ignition of the user, when the bracket 120 is judged to be in the short-term uncooked pan state, the control part controls the flame generation part 130 to reduce the flame generated by the flame generation part, so that the waste amount of the fuel gas is reduced, and the utilization rate of the fuel gas is improved.

It can be understood that, when the pot is not placed on the rack 120 again for a long time after leaving the rack 120 for a short time, that is, the rack 120 is switched from the short-term uncooked pot state to the long-term uncooked pot state, the control part controls the flame generation part 130 to turn off the flame generated by itself.

The control unit collects the temperature value of the detecting element 220 according to a preset sampling period, that is, the control unit collects the temperature value of the detecting element 220 once in each sampling period. In this case, the detecting element 220 may acquire the temperature of the cooktop once in one sampling period. The sampling period may be 0.5s, 1s, 2s, 5s, 10s, etc.

When the collected temperature value satisfies the first condition, it is determined that the rack 120 is in a long-term uncooked state. Preferably, the first condition is: n temperature values obtained in N continuous sampling periods are all larger than a high-temperature threshold value. When the temperature sensor is actually used, the control part acquires N temperature values after collecting N continuous sampling periods. And judging whether each temperature value is larger than a high-temperature threshold value. When all temperature values in the N temperature values are greater than the high temperature threshold, it indicates that the temperature of the flame at the cooking range is obtained by the detecting element 220 in the time period corresponding to the consecutive N sampling periods, that is, no pot is placed on the rack 120 all the time, which indicates that the rack 120 is in a long-term non-pot sitting state. The high temperature threshold is set according to the type of the gas, for example, when the gas is coal gas, the low temperature threshold may be 1000 ℃, and when the gas is natural gas, the high temperature threshold may be 2000 ℃. Of course, the setting may be made according to a default value, for example, 800 ℃.

Of course, in other embodiments, the first condition may also be in other forms, for example, the temperature change rate in the N temperature values obtained in the consecutive N sampling periods is smaller than the temperature increase threshold or the temperature decrease threshold mentioned later, and the temperature value in the first sampling period and the temperature value in the nth sampling period are both larger than the high temperature threshold.

When the collected temperature value satisfies the second condition, it is determined that the rack 120 is in the short-term uncooked state. Preferably, the second condition is: the heating rate of the temperature values obtained in M continuous sampling periods is greater than the heating threshold value, and M is a positive integer and is greater than 1. In the cooking process, when the user moves the pot halfway (for example, when the user pours the food in the pot into the dish), the detecting part 220 obtains the temperature of the flame at the cooking range at the moment of moving the pot, that is, the temperature obtained by the detecting part 220 may rise sharply in a period of time. At this time, when analyzing the M collected temperature values, the control unit finds that the temperatures of the M temperature values gradually increase, and the temperature increase rate is greater than the temperature increase threshold value. For example, when the 2 temperature values collected by the control part are increased in number and the heating rate is greater than the heating threshold value, it indicates that the former temperature value is the temperature when the pot is seated, and the latter temperature value is the temperature when the pot is removed. It is understood that M is less than N. Alternatively, the temperature rise rate of the temperature values acquired in M consecutive sampling periods may be a ratio of a difference between the temperature value acquired in the first sampling period and the temperature value acquired in the mth sampling period to time. Alternatively, the maximum slope value of the curve formed by the M temperature values and the M time points is obtained. And is not particularly limited. Or, in M sampling periods, the ratio of the maximum value of the difference between the temperature values obtained in the previous and next sampling periods to the time corresponding to the sampling period may be used.

Of course, in other embodiments, the first condition may also be in other forms, for example, q temperature values obtained in q consecutive sampling periods are all greater than the high temperature threshold, and q temperature values obtained in q consecutive sampling periods are all less than the cooking threshold (which refers to the highest temperature that the pot or food can reach while cooking, and is less than the high temperature threshold).

Through the scheme in this embodiment, can open a fire and do not sit the pot for a long time or when the culinary art finishes forgetting to close a fire, self-closing flame, can also reduce the flame size when the user briefly moves away the pan in culinary art in-process, not only show the waste that has reduced the gas, and show and improve the gas utilization ratio, can also avoid the user when the culinary art briefly moves the pot, repeated ignition, convenience of customers's use, and close flame when the user does not use the pan for a long time, avoid causing incident such as conflagration.

Referring to fig. 3, a flow chart of a method for controlling a range combination kitchen ware in another embodiment of the present application is shown, and compared with the embodiment shown in fig. 2, the difference is that the method further includes step S23 and step S40, which are detailed as follows:

s23, when the temperature value meets a third condition, judging that the bracket 120 is in the pot sitting state;

s40, when the rack 120 is switched from the short-term un-seated state to the seated state, the flame generator 130 is controlled to increase the flame generated by itself.

In this embodiment, the control unit may further determine that the rack 120 is in the sitting state based on the third condition. When support 120 is in sitting the pot state, that is to say placed the pan on support 120, the user is in the culinary art in-process. Generally, when the rack 120 is in the pot-sitting state, the control part does not give a control instruction to the flame generation part 130, and the flame generation part 130 keeps the current flame size and adjusts the flame size along with the user operation. It can be understood that, when the rack 120 is in the pot sitting state, the temperature value detected by the detecting element 220 is the temperature of the food in the pot, the temperature of the food rises at a relatively slow temperature rising rate and finally tends to be stable, and the temperature value of the detecting element 220 does not exceed the high temperature threshold, and the temperature value collected by the control part does not satisfy the condition that the rack 120 is switched to the non-pot sitting state, that is, the rack 120 sits on the pot all the time.

Wherein, the third condition may be: when the temperature values obtained in the current n continuous sampling periods are all smaller than the temperature values obtained in the previous n continuous sampling periods, and the difference value is larger than the cooling threshold value, the pot sitting position of the support 120 is judged, and n is a positive integer. When the temperature value that current n consecutive sampling periods that the control part gathered all were less than the temperature value that n consecutive sampling periods acquireed before, and the difference is greater than the cooling threshold value around and, it is great to explain the temperature grow difference that detection piece 220 detected, that is to say, the temperature value of n consecutive sampling periods of preceding corresponds the temperature of gathering the flame of kitchen range eye department, and the pot is not sat to support 120 this moment, and the temperature value of n consecutive sampling periods of next corresponds the temperature of the time pan of gathering, and support 120 sits the pot this moment. Thus, it can be determined that the rack 120 is switched to the pot sitting state, that is, the rack 120 is already sitting on the pot. In the specific determination, whether the support 120 is seated on the pan may be determined based on a comparison between a difference value between an average value, a variance, a standard deviation, a maximum value, a minimum value of n temperature values obtained in n consecutive sampling periods and a cooling threshold value, which is not limited herein. Wherein N is less than N/2.

It can be understood that, when the pan was placed suddenly on support 120, because the pan temperature is lower, the temperature difference of detection piece 220 is great, sets up the cooling threshold value this moment, when the temperature difference was greater than the cooling threshold value, just judges support 120 and sits the pot, can filter and get rid of because of the user cooks in-process and add water, gather the judgement mistake that the temperature value descends and arouse when action such as dish.

In the present embodiment, when it is determined that the rack 120 is in the pot sitting state after step S32, it indicates that the rack 120 is switched from the short-term non-pot sitting state to the pot sitting state again. That is, the user will put back the pot again after removing the pot for a while and continue cooking, because the user has removed the pot for a while, the control part has already turned down the flame size of the flame generation part 130 after removing the pot for a while, can't meet the temperature requirement that the cooking needs, therefore carry out step S40, when the support 120 switches from the short-term not sitting on the pot state to sitting on the pot state, the control part controls the flame generation part 130 to increase the flame that self produces, so that the flame size meets the cooking needs. Therefore, the flame size can be prevented from being manually adjusted by a user, the use of the user is facilitated, and the user experience is improved.

Please refer to fig. 4, which is a flowchart illustrating a method for controlling a range combination kitchen ware in another embodiment of the present application, compared with the embodiment shown in fig. 1, the difference is that the method further includes a step S50 before the step S20, and the step S30 includes a step S33, which is detailed as follows:

s50, responding to a switching signal triggered by the interaction part 230 on the cigarette making machine 200;

In actual operation, when the user acts on the interaction part 230 and triggers the switching signal, the control part responds to the switching signal and controls the flame generation part 130 to directly turn off the flame when the bracket 120 is not seated on the pan. Thus, as long as no pot is placed on the rack 120, the flame generating part 130 will shut off its own flame. That is, the flame is directly turned off in either the long-term unsettled state or the short-term unsettled state. Different use requirements and use habits of users can be met.

At this time, the interactive part 230 is simple in form, low in cost and convenient to operate compared with interactive structures such as a touch screen when passing through the button. In practical application, the switching signal may be triggered when the switch button is pressed, and the switching signal may not be triggered when the switch button is bounced.

Further, the interaction portion 230, the flame generation portion 130, the cooktop and the detection pieces 220 are all provided in plurality, each detection piece 220 is respectively arranged towards one cooktop, and each interaction portion 230 corresponds to one flame generation portion 130. The control part responds to the switching signal formed by each interaction part 230 and controls the flame generation part 130 corresponding to the interaction part 230 to turn off the flame generated by itself when the bracket 120 on the cooking range where the flame generation part 130 corresponding to the interaction part 230 is located is not seated. In this embodiment, one interaction portion 230 correspondingly controls one flame generation portion 130, so that each flame generation portion 130 can be separately controlled, the application is more flexible, and the diversified requirements of users can be met.
