[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on March 5, 2024, with application number "202410250837.5" and application name "Cooking appliance and its control method, device, electronic device and readable storage medium", the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of household appliances, and in particular to a cooking appliance and a control method, device, electronic device, and readable storage medium thereof. Background Art

[0003] At present, the cavity setting of cooking utensils can improve cooking efficiency and is unanimously favored by users.

[0004] However, in the related art, for cooking utensils with separate cavities, such as cooking utensils with upper and lower cavities, a target temperature is set for the upper cavity and a target temperature is set for the lower cavity. The temperatures of the upper cavity and the lower cavity will interfere with each other, causing the temperatures of the two cavities to fluctuate greatly, affecting the cooking effect. Summary of the Invention

[0005] This application aims to solve at least one of the technical problems existing in the prior art or related art.

[0006] To this end, a first aspect of the present application provides a method for controlling a cooking appliance.

[0007] A second aspect of the present application further provides a control device for a cooking appliance.

[0008] A third aspect of the present application also provides a cooking utensil.

[0009] The fourth aspect of the present application also provides an electronic device.

[0010] The fifth aspect of the present application also provides a readable storage medium.

[0011] In view of this, the first aspect of the present application proposes a control method for a cooking appliance, the cooking appliance comprising a first cavity, a second cavity and at least two heating parts, the at least two heating parts being used to provide heat to the first cavity and the second cavity respectively, the control method comprising: receiving an operation input to the cooking appliance; in response to the operation input, turning on the at least two heating parts, and obtaining a first temperature value of the first cavity and a second temperature value of the second cavity; when the first temperature value is greater than or equal to a first target temperature value and the second temperature value is greater than or equal to a second target temperature value, determining a first on-off ratio of the heating part corresponding to the first cavity and a second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value, and controlling the at least two heating parts to operate at the first on-off ratio and the second on-off ratio.

[0012] The present application provides a control method for a cooking appliance, which includes at least a first cavity, a second cavity, and at least two heating units. The at least two heating units are used to heat the first and second cavities, respectively, to achieve separate cooking of ingredients within the first and second cavities. This allows the simultaneous cooking of different types of ingredients using the same cooking appliance, thereby improving cooking efficiency. The control method includes receiving an operation input to the cooking appliance and, in response to the operation input, activating the at least two heating units so that the at least two heating units heat the first and second cavities, respectively, to cook the ingredients within the first and second cavities. A first temperature value in the first cavity and a second temperature value in the second cavity are obtained. When the first temperature value in the first cavity is greater than or equal to the first target temperature value, and the second temperature value is greater than or equal to the second target temperature value, it indicates that the temperatures in the first cavity and the second cavity have reached the target temperatures. At this time, the first on-off ratio and the second on-off ratio corresponding to the at least two heating parts are determined according to the first target temperature value and the second target temperature value. Then, under the mutual influence of the first cavity and the second cavity, the first cavity is maintained near the first target temperature value and the second cavity is maintained near the second target temperature value, thereby preventing the temperatures in the first cavity and the second cavity from being too high and shortening the amplitude of the temperature change.

[0013] It can be understood that at least two heating units supply heat to the first cavity and the second cavity respectively, thereby realizing independent temperature control of the first cavity and the second cavity. Since at least two heating units supply heat to the first cavity and the second cavity respectively, the temperature in the first cavity and the temperature in the second cavity will affect each other. The present application can determine the first on-off ratio corresponding to the first cavity and the second on-off ratio corresponding to the second cavity according to the first target temperature value and the second target temperature value, so that the first on-off ratio and the second on-off ratio are both associated with the first target temperature value and the second target temperature value. That is, after the first cavity is heated to the first target temperature value and the second cavity is heated to the second target temperature value, the at least two heating units are respectively controlled to operate at the on-off ratio associated with the first target temperature value and the second target temperature value, so that the temperature in the first cavity and the temperature in the second cavity can be coordinated with each other, avoiding ignoring the influence of the other cavity when controlling one cavity alone, so that the first cavity and the second cavity are both near the target temperature, avoiding the situation where the temperature in the first cavity and the temperature in the second cavity fluctuate too much.

[0014] In a specific application, the temperature rise process in the first cavity and the second cavity includes a temperature rise period and a constant temperature period. In the temperature rise period, at least two heating units are both turned on, so that the temperature in the first cavity is rapidly raised to a first target temperature value, and the temperature in the second cavity is rapidly raised to a second target temperature value. In the constant temperature period, the first on-off ratio and the second on-off ratio are determined based on the first target temperature value and the second target temperature value, so that the temperature in the first cavity is maintained near the first target temperature value, and the temperature in the second cavity is maintained near the second target temperature value, thereby preventing excessive temperature fluctuations in the first cavity and the second cavity.

[0015] It should be noted that after the temperature in the first cavity and the temperature in the second cavity reach the corresponding target temperature, the heating part is controlled to heat for a period of time and then turn off for a period of time, and so on and so forth, so that the heating part has a ratio of power-on time to power-off time in each power-on and power-off cycle. The first on-off ratio is the ratio of the power-on time to the power-off time of the heating part corresponding to the first cavity, and the second on-off ratio is the ratio of the power-on time to the power-off time of the heating part corresponding to the second cavity.

[0016] The cooking appliance control method provided in this application may also have the following additional technical features:

[0017] In some embodiments, exemplarily, the steps of determining a first on-off ratio of the heating part corresponding to the first cavity and a second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value include: when the first target temperature value is greater than the second target temperature value, determining a first preset on-off ratio of the heating part corresponding to the first cavity according to the first temperature value and the first target temperature value, and determining the first on-off ratio as the first preset on-off ratio; determining the second preset on-off ratio of the heating part corresponding to the second cavity according to the second temperature value and the second target temperature value; determining the average on-off ratio according to the first target temperature value and the second target temperature value; when the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, determining the second on-off ratio as the difference between the average on-off ratio and the first preset on-off ratio.

[0018] In this embodiment, the step of determining the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value specifically includes: comparing the first target temperature value and the second target temperature value, and when the first target temperature value is greater than the second target temperature value, first controlling the first cavity with a higher temperature requirement so that the heating part of the first cavity operates at a first preset on-off ratio determined according to the first target temperature value and the first temperature value, that is, using the first preset on-off ratio as the first on-off ratio, so that the heating part intermittently heats the first cavity, thereby maintaining the temperature in the first cavity near the first target temperature value. Then, the second preset on-off ratio corresponding to the heating part of the second cavity is determined according to the second temperature value and the second target temperature value in the second cavity. Since the temperature in the first cavity affects the second cavity, the operation of the heating part corresponding to the second cavity is not controlled according to the second preset on-off ratio at this time. For example, the average on-off ratio between the two can be determined according to the first target temperature value and the second target temperature value. When the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, the difference between the average on-off ratio and the first preset on-off ratio is used as the second on-off ratio, and then the heating part corresponding to the second cavity is controlled according to the second on-off ratio to balance the influence of the temperature of the first cavity on the second cavity, avoid the temperature of the second cavity from fluctuating, and maintain the temperature stability in the second cavity.

[0019] In some embodiments, exemplarily, the control method of the cooking appliance further includes: when the second temperature value is greater than or equal to the sum of the second target temperature value and the first threshold value, controlling the heating part corresponding to the second cavity to be turned off; when the second temperature value is less than or equal to the difference between the second target temperature value and the first threshold value, controlling the heating part corresponding to the second cavity to operate at a third preset on-off ratio.

[0020] In this embodiment, the control method of the cooking appliance also includes: when the second temperature value in the second cavity is greater than or equal to the sum of the second target temperature value and the first threshold value, the temperature in the second cavity is higher, and at this time, the heating part corresponding to the second cavity is turned off, so that the temperature in the second cavity gradually decreases to the second target temperature value; when the second temperature value in the second cavity is less than or equal to the difference between the second target temperature value and the first threshold value, it means that the difference between the second temperature value in the second cavity and the second target temperature value is large, and at this time, the heating part corresponding to the second cavity is controlled to operate at a third preset on-off ratio, so that the temperature in the second cavity quickly rises to the second target temperature value, and then when the temperature in the second cavity is controlled by the first target temperature value and the second target temperature value, the temperature in the second cavity is avoided from being too high or too low.

[0021] In some embodiments, for example, when the second target temperature value is greater than the first target temperature value, the second preset on-off ratio is determined based on the second temperature value and the second target temperature value, and the second on-off ratio is determined to be the second preset on-off ratio; the first preset on-off ratio of the heating part corresponding to the first cavity is determined based on the first temperature value and the first target temperature value; when the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, the first on-off ratio is determined to be the difference between the average on-off ratio and the second preset on-off ratio.

[0022] In this embodiment, when the second target temperature value is greater than the first target temperature value, the target temperature corresponding to the second cavity is higher. In this case, the heating unit corresponding to the second cavity is controlled to operate at a second preset on-off ratio determined based on the second target temperature value and the second temperature value. That is, the second preset on-off ratio is set to the second on-off ratio, so that the temperature in the second cavity is maintained near the second target temperature value. At the same time, the first preset on-off ratio of the heating unit corresponding to the first cavity is determined based on the first temperature value and the first target temperature value. If the sum of the first preset on-off ratio and the second preset on-off ratio is greater than the average on-off ratio, it means that the second preset on-off ratio is higher. In this case, the first on-off ratio is determined as the difference between the average on-off ratio and the second preset on-off ratio, thereby ensuring that the temperature in the first cavity is not too high or too low, while balancing the impact of the higher temperature of the second cavity on the first cavity.

[0023] In some embodiments, for example, when the first temperature value is greater than or equal to the sum of the first target temperature value and the second threshold value, the heating part corresponding to the first cavity is controlled to be turned off; when the first temperature value is less than or equal to the difference between the first target temperature value and the second threshold value, the heating part corresponding to the first cavity is controlled to operate at a fourth preset on-off ratio.

[0024] In this embodiment, when the first temperature value is greater than or equal to the sum of the first target temperature value and the second threshold value, it means that the temperature in the first cavity is high. At this time, the heating part corresponding to the first cavity is turned off, so that the temperature in the first cavity is reduced, thereby avoiding the occurrence of burnt food due to high-temperature baking; when the first temperature value is less than or equal to the difference between the first target temperature value and the second threshold value, it means that the temperature in the first cavity is low. At this time, the heating part corresponding to the first cavity is controlled to operate at a fourth preset on-off ratio, thereby causing the temperature in the first cavity to rise rapidly, thereby avoiding the first cavity being at a low temperature for a long time and affecting the cooking process.

[0025] In some embodiments, exemplarily, the step of determining a first preset on-off ratio of the heating part corresponding to the first cavity according to the first temperature value and the first target temperature value includes: determining the first preset on-off ratio by a PID algorithm according to the first temperature value and the first target temperature value; the step of determining a second preset on-off ratio of the heating part corresponding to the second cavity according to the second temperature value and the second target temperature value includes: determining the second preset on-off ratio by a PID (proportional, integral, differential) algorithm according to the second temperature value and the second target temperature value; the step of determining an average on-off ratio according to the first target temperature value and the second target temperature value includes: determining the corresponding average on-off ratio according to the average value of the first target temperature value and the second target temperature value.

[0026] In this embodiment, determining a first preset on-off ratio for a heating unit corresponding to a first cavity based on a first temperature value and a first target temperature value specifically includes determining the first preset on-off ratio based on a PID algorithm based on the first temperature value and the first target temperature value, such that when the heating unit operates according to the first preset on-off ratio, the temperature in the first cavity is maintained near the first target temperature value. Determining a second preset on-off ratio for a heating unit corresponding to a second cavity based on a second temperature value and a second target temperature value includes determining the second preset on-off ratio based on the second temperature value and the second target temperature value using a PID algorithm, such that when the heating unit provides heat to the second cavity at the second preset on-off ratio, the temperature in the second cavity is maintained near the second target temperature value. Determining an average on-off ratio based on the first target temperature value and the second target temperature value specifically includes determining the corresponding average on-off ratio based on the average of the first target temperature value and the second target temperature value, thereby finding a balance point between the target temperatures of the first and second cavities.

[0027] According to the second aspect of the present application, a control device for a cooking appliance is also proposed. The cooking appliance includes a first cavity, a second cavity and at least two heating parts, and the at least two heating parts are used to supply heat to the first cavity and the second cavity respectively. The control device includes: a receiving unit for receiving operation input to the cooking appliance; a response unit for responding to the operation input; a control unit for turning on the at least two heating parts and obtaining a first temperature value of the first cavity and a second temperature value of the second cavity. When the first temperature value is greater than or equal to a first target temperature value and the second temperature value is greater than or equal to the second target temperature value, the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity are determined according to the first target temperature value and the second target temperature value, and the at least two heating parts are controlled to operate at the first on-off ratio and the second on-off ratio.

[0028] The second aspect of the present application provides a control device for a cooking appliance, comprising a receiving unit, a responding unit, and a control unit. The receiving unit is configured to receive an operation input to the cooking appliance. After the responding unit responds to the operation input, the control unit activates at least two heating units, causing the at least two heating units to heat a first cavity and a second cavity, respectively, thereby cooking the food in the first and second cavities. A first temperature value in the first cavity and a second temperature value in the second cavity are obtained. When the first temperature value in the first cavity is greater than or equal to a first target temperature value, and the second temperature value is greater than or equal to a second target temperature value, it indicates that the temperatures in the first and second cavities have both reached the target temperatures. At this time, a first on-off ratio and a second on-off ratio corresponding to the at least two heating units are determined based on the first and second target temperature values. Then, under the mutual influence of the first and second cavities, the first cavity is maintained near the first target temperature value, and the second cavity is maintained near the second target temperature value, thereby preventing the temperatures in the first and second cavities from being too high and shortening the amplitude of the temperature change.

[0029] According to the third aspect of the present application, a cooking appliance is also proposed, comprising: a first cavity; a second cavity; at least two heating parts, the at least two heating parts being used to provide heat to the first cavity and the second cavity respectively; and a control device as proposed in the second aspect.

[0030] The cooking device provided by the present application includes a first cavity, a second cavity, and at least two heating units. The at least two heating units are respectively used to heat the first cavity and the second cavity, thereby achieving separate cavity cooking of the food in the first cavity and the second cavity. In addition, different types of food can be cooked simultaneously using the same cooking device, thereby improving cooking efficiency. At the same time, the control device can also determine the first on-off ratio and the second on-off ratio corresponding to the at least two heating units based on the first target temperature value and the second target temperature value when the first temperature value in the first cavity is greater than or equal to the first target temperature value and the second temperature value is greater than or equal to the second target temperature value. Then, under the mutual influence of the first cavity and the second cavity, the first cavity is kept near the first target temperature value and the second cavity is kept near the second target temperature value, thereby preventing the temperature in the first cavity and the second cavity from being too high and shortening the amplitude of temperature change.

[0031] In some embodiments, exemplarily, the cooking utensil further includes: a shell; a partition, the partition being arranged in the shell, the partition dividing the shell into at least a first cavity and a second cavity; wherein, one of the first cavity and the second cavity is located on top of the other, or one of the first cavity and the second cavity is located on one side of the other.

[0032] In this embodiment, the cooking appliance also includes a shell and a partition, which is arranged in the shell to separate the space in the shell into a first cavity and a second cavity. Exemplarily, the first cavity and the second cavity are distributed in a vertical direction so that one of the first cavity and the second cavity is located on top of the other, or the first cavity and the second cavity are distributed in a horizontal direction so that one of the first cavity and the second cavity is located on one side of the other.

[0033] According to the fourth aspect of the present application, an electronic device is also proposed, comprising: a processor and a memory, the memory storing programs or instructions that can be run on the processor, and when the programs or instructions are executed by the processor, the steps of the control method of the cooking appliance proposed in any of the above items are implemented.

[0046] In order to more clearly understand the above-mentioned objects, features and advantages of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0048] The following describes a cooking appliance and a control method, device, electronic device, and readable storage medium thereof according to some embodiments of the present application with reference to FIG. 1 to FIG. 6 .

[0049] According to one embodiment of the present application, a control method for a cooking appliance is proposed. The cooking appliance includes a first cavity, a second cavity, and at least two heating parts, where the at least two heating parts are used to provide heat to the first cavity and the second cavity, respectively.

[0050] As shown in FIG1 , a flow chart of a method for controlling a cooking appliance is shown, including:

[0051] Step 102: receiving an operation input for a cooking appliance;

[0052] Step 104: In response to the operation input, turn on at least two heating units, and obtain a first temperature value of the first cavity and a second temperature value of the second cavity;

[0053] Step 106: When the first temperature value is greater than or equal to the first target temperature value and the second temperature value is greater than or equal to the second target temperature value, determine the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value, and control at least two heating parts to operate at the first on-off ratio and the second on-off ratio.

[0054] The present application provides a control method for a cooking appliance, which includes at least a first cavity, a second cavity, and at least two heating units. The at least two heating units are used to heat the first and second cavities, respectively, to achieve separate cooking of ingredients within the first and second cavities. This allows the simultaneous cooking of different types of ingredients using the same cooking appliance, thereby improving cooking efficiency. The control method includes receiving an operation input to the cooking appliance and, in response to the operation input, activating the at least two heating units so that the at least two heating units heat the first and second cavities, respectively, to cook the ingredients within the first and second cavities. A first temperature value in the first cavity and a second temperature value in the second cavity are obtained. When the first temperature value in the first cavity is greater than or equal to the first target temperature value, and the second temperature value is greater than or equal to the second target temperature value, it indicates that the temperatures in the first cavity and the second cavity have reached the target temperatures. At this time, the first on-off ratio and the second on-off ratio corresponding to the at least two heating parts are determined according to the first target temperature value and the second target temperature value. Then, under the mutual influence of the first cavity and the second cavity, the first cavity is maintained near the first target temperature value and the second cavity is maintained near the second target temperature value, thereby preventing the temperatures in the first cavity and the second cavity from being too high and shortening the amplitude of the temperature change.

[0055] It can be understood that at least two heating units supply heat to the first cavity and the second cavity respectively, thereby realizing independent temperature control of the first cavity and the second cavity. Since at least two heating units supply heat to the first cavity and the second cavity respectively, the temperature in the first cavity and the temperature in the second cavity will affect each other. The present application can determine the first on-off ratio corresponding to the first cavity and the second on-off ratio corresponding to the second cavity according to the first target temperature value and the second target temperature value, so that the first on-off ratio and the second on-off ratio are both associated with the first target temperature value and the second target temperature value. That is, after the first cavity is heated to the first target temperature value and the second cavity is heated to the second target temperature value, the at least two heating units are respectively controlled to operate at the on-off ratio associated with the first target temperature value and the second target temperature value, so that the temperature in the first cavity and the temperature in the second cavity can be coordinated with each other, avoiding ignoring the influence of the other cavity when controlling one cavity alone, so that the first cavity and the second cavity are both near the target temperature, avoiding the situation where the temperature in the first cavity and the temperature in the second cavity fluctuate too much.

[0056] In a specific application, as shown in FIG2 , the temperature rise process in the first cavity and the second cavity includes a temperature rise section (e.g., section B) and a constant temperature section (e.g., section C). The line A1 in FIG2 is the temperature rise curve of the first cavity, and the line A2 is the temperature rise curve of the second cavity. In the temperature rise section, at least two heating parts are both turned on, so that the temperature in the first cavity rises rapidly to the first target temperature value, and the temperature in the second cavity rises rapidly to the second target temperature value. In the constant temperature section, the first on-off ratio and the second on-off ratio are determined by the first target temperature value and the second target temperature value, so that the temperature in the first cavity is maintained near the first target temperature value, and the temperature in the second cavity is maintained near the second target temperature value, so as to avoid excessive fluctuations in the temperature in the first cavity and the temperature in the second cavity.

[0057] It should be noted that after the temperature in the first cavity and the temperature in the second cavity reach the corresponding target temperature, the heating part is controlled to heat for a period of time and then turn off for a period of time, and so on and so forth, so that the heating part has a ratio of power-on time to power-off time in each power-on and power-off cycle. The first on-off ratio is the ratio of the power-on time to the power-off time of the heating part corresponding to the first cavity, and the second on-off ratio is the ratio of the power-on time to the power-off time of the heating part corresponding to the second cavity.

[0058] Exemplarily, the operation input is an operation of the cooking appliance by the user, such as turning on a heating function of the cooking appliance.

[0059] In some embodiments, exemplarily, the steps of determining a first on-off ratio of the heating part corresponding to the first cavity and a second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value include: when the first target temperature value is greater than the second target temperature value, determining a first preset on-off ratio of the heating part corresponding to the first cavity according to the first temperature value and the first target temperature value, and determining the first on-off ratio as the first preset on-off ratio; determining the second preset on-off ratio of the heating part corresponding to the second cavity according to the second temperature value and the second target temperature value; determining the average on-off ratio according to the first target temperature value and the second target temperature value; when the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, determining the second on-off ratio as the difference between the average on-off ratio and the first preset on-off ratio.

[0060] In this embodiment, the step of determining the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value specifically includes: comparing the first target temperature value and the second target temperature value, and when the first target temperature value is greater than the second target temperature value, first controlling the first cavity with a higher temperature requirement so that the heating part of the first cavity operates at a first preset on-off ratio determined according to the first target temperature value and the first temperature value, that is, using the first preset on-off ratio as the first on-off ratio, so that the heating part intermittently heats the first cavity, thereby maintaining the temperature in the first cavity near the first target temperature value. Then, the second preset on-off ratio corresponding to the heating part of the second cavity is determined according to the second temperature value and the second target temperature value in the second cavity. Since the temperature in the first cavity affects the second cavity, the operation of the heating part corresponding to the second cavity is not controlled according to the second preset on-off ratio at this time. For example, the average on-off ratio between the two can be determined according to the first target temperature value and the second target temperature value. When the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, the difference between the average on-off ratio and the first preset on-off ratio is used as the second on-off ratio, and then the heating part corresponding to the second cavity is controlled according to the second on-off ratio to balance the influence of the temperature of the first cavity on the second cavity, avoid the temperature of the second cavity from fluctuating, and maintain the temperature stability in the second cavity.

[0061] Exemplarily, when the sum of the first preset on-off ratio and the second preset on-off ratio is smaller than the average on-off ratio, the second on-off ratio is determined to be the second preset on-off ratio.

[0062] In some embodiments, exemplarily, the control method of the cooking appliance further includes: when the second temperature value is greater than or equal to the sum of the second target temperature value and the first threshold value, controlling the heating part corresponding to the second cavity to be turned off; when the second temperature value is less than or equal to the difference between the second target temperature value and the first threshold value, controlling the heating part corresponding to the second cavity to operate at a third preset on-off ratio.

[0063] In this embodiment, the control method of the cooking appliance also includes: when the second temperature value in the second cavity is greater than or equal to the sum of the second target temperature value and the first threshold value, the temperature in the second cavity is higher, and at this time, the heating part corresponding to the second cavity is turned off, so that the temperature in the second cavity gradually decreases to the second target temperature value; when the second temperature value in the second cavity is less than or equal to the difference between the second target temperature value and the first threshold value, it means that the difference between the second temperature value in the second cavity and the second target temperature value is large, and at this time, the heating part corresponding to the second cavity is controlled to operate at a third preset on-off ratio, so that the temperature in the second cavity quickly rises to the second target temperature value, and then when the temperature in the second cavity is controlled by the first target temperature value and the second target temperature value, the temperature in the second cavity is avoided from being too high or too low.

[0064] In a specific application, the first threshold is set according to actual conditions. For example, the first threshold is greater than or equal to 2° C. and less than or equal to 5° C. For example, the first threshold is equal to 3° C.

[0065] Exemplarily, in this embodiment, in the constant temperature section, when the second temperature value in the second cavity is greater than the difference between the second target temperature value and the first threshold value, and less than the sum of the second target temperature value and the first threshold value, the second on-off ratio is controlled to be the difference between the average on-off ratio and the first preset on-off ratio.

[0066] In some embodiments, for example, when the second target temperature value is greater than the first target temperature value, the second preset on-off ratio is determined based on the second temperature value and the second target temperature value, and the second on-off ratio is determined to be the second preset on-off ratio; the first preset on-off ratio of the heating part corresponding to the first cavity is determined based on the first temperature value and the first target temperature value; when the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, the first on-off ratio is determined to be the difference between the average on-off ratio and the second preset on-off ratio.

[0067] In this embodiment, when the second target temperature value is greater than the first target temperature value, the target temperature corresponding to the second cavity is higher. In this case, the heating unit corresponding to the second cavity is controlled to operate at a second preset on-off ratio determined based on the second target temperature value and the second temperature value. That is, the second preset on-off ratio is set to the second on-off ratio, so that the temperature in the second cavity is maintained near the second target temperature value. At the same time, the first preset on-off ratio of the heating unit corresponding to the first cavity is determined based on the first temperature value and the first target temperature value. If the sum of the first preset on-off ratio and the second preset on-off ratio is greater than the average on-off ratio, it means that the second preset on-off ratio is higher. In this case, the first on-off ratio is determined as the difference between the average on-off ratio and the second preset on-off ratio, thereby ensuring that the temperature in the first cavity is not too high or too low, while balancing the impact of the higher temperature of the second cavity on the first cavity.

[0068] Exemplarily, when the sum of the first preset on-off ratio and the second preset on-off ratio is smaller than the average on-off ratio, the first on-off ratio is determined to be the first preset on-off ratio.

[0069] In some embodiments, for example, when the first temperature value is greater than or equal to the sum of the first target temperature value and the second threshold value, the heating part corresponding to the first cavity is controlled to be turned off; when the first temperature value is less than or equal to the difference between the first target temperature value and the second threshold value, the heating part corresponding to the first cavity is controlled to operate at a fourth preset on-off ratio.

[0070] In this embodiment, when the first temperature value is greater than or equal to the sum of the first target temperature value and the second threshold value, it means that the temperature in the first cavity is high. At this time, the heating part corresponding to the first cavity is turned off, so that the temperature in the first cavity is reduced, thereby avoiding the occurrence of burnt food due to high-temperature baking; when the first temperature value is less than or equal to the difference between the first target temperature value and the second threshold value, it means that the temperature in the first cavity is low. At this time, the heating part corresponding to the first cavity is controlled to operate at a fourth preset on-off ratio, thereby causing the temperature in the first cavity to rise rapidly, thereby avoiding the first cavity being at a low temperature for a long time and affecting the cooking process.

[0071] In a specific application, the second threshold is set according to actual conditions. For example, the second threshold is greater than or equal to 2° C. and less than or equal to 5° C. For example, the second threshold is equal to 3° C.

[0072] Exemplarily, in this embodiment, in the constant temperature section, when the first temperature value in the first cavity is greater than the difference between the first target temperature value and the second threshold value, and less than the sum of the first target temperature value and the second threshold value, the first on-off ratio is controlled to be the difference between the average on-off ratio and the second preset on-off ratio.

[0073] In some embodiments, exemplarily, the step of determining a first preset on-off ratio of the heating part corresponding to the first cavity according to the first temperature value and the first target temperature value includes: determining the first preset on-off ratio through a PID algorithm according to the first temperature value and the first target temperature value; the step of determining a second preset on-off ratio of the heating part corresponding to the second cavity according to the second temperature value and the second target temperature value includes: determining the second preset on-off ratio through a PID algorithm according to the second temperature value and the second target temperature value; the step of determining an average on-off ratio according to the first target temperature value and the second target temperature value includes: determining the corresponding average on-off ratio according to the average value of the first target temperature value and the second target temperature value.

[0074] In this embodiment, determining a first preset on-off ratio for a heating unit corresponding to a first cavity based on a first temperature value and a first target temperature value specifically includes determining the first preset on-off ratio based on the first temperature value and the first target temperature value using a PID algorithm, such that when the heating unit operates according to the first preset on-off ratio, the temperature in the first cavity is maintained near the first target temperature value. Determining a second preset on-off ratio for a heating unit corresponding to a second cavity based on a second temperature value and a second target temperature value includes determining the second preset on-off ratio based on the second temperature value and the second target temperature value using a PID algorithm, such that when the heating unit provides heat to the second cavity at the second preset on-off ratio, the temperature in the second cavity is maintained near the second target temperature value. Determining an average on-off ratio based on the first target temperature value and the second target temperature value specifically includes determining the corresponding average on-off ratio based on the average of the sum of the first target temperature value and the second target temperature value, thereby finding a balance point between the target temperatures of the first and second cavities.

[0075] It can be understood that the PID algorithm is: a basic form of digital PID control algorithm, which is a control algorithm that performs PID control by increasing the control quantity (the difference between the current control quantity and the previous control quantity).

[0076] For example, in the setting, the average on-off ratio corresponding to the average value of the sum of the first target temperature value and the second target temperature value can be obtained by basic table lookup.

[0077] For example, a table of average on-off ratios corresponding to an average value of the sum of the first target temperature value and the second target temperature value may be stored in advance in the cooking appliance.

[0078] As shown in Figure 5, according to an embodiment of the present application, a control device 6 for a cooking appliance is also proposed. The cooking appliance includes a first cavity, a second cavity and at least two heating parts, and the at least two heating parts are used to provide heat to the first cavity and the second cavity respectively. The control device 6 includes: a receiving unit 601, used to receive operation input to the cooking appliance; a response unit 602, used to respond to the operation input; a control unit 603, used to turn on the at least two heating parts, and obtain the first temperature value of the first cavity and the second temperature value of the second cavity. When the first temperature value is greater than or equal to the first target temperature value and the second temperature value is greater than or equal to the second target temperature value, the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity are determined according to the first target temperature value and the second target temperature value, and the at least two heating parts are controlled to operate at the first on-off ratio and the second on-off ratio.

[0079] The control device 6 of the cooking appliance provided in the present application includes a receiving unit 601, a response unit 602, and a control unit 603. The receiving unit 601 is used to receive an operation input to the cooking appliance. After the response unit 602 responds to the operation input, the control unit 603 turns on at least two heating units, so that the at least two heating units respectively provide heat to the first cavity and the second cavity to cook the food in the first cavity and the second cavity. A first temperature value in the first cavity and a second temperature value in the second cavity are obtained. When the first temperature value in the first cavity is greater than or equal to the first target temperature value, and the second temperature value is greater than or equal to the second target temperature value, it means that the temperatures in the first cavity and the second cavity have reached the target temperature. At this time, the first on-off ratio and the second on-off ratio corresponding to the at least two heating units are determined based on the first target temperature value and the second target temperature value. Then, under the mutual influence of the first cavity and the second cavity, the first cavity is kept near the first target temperature value and the second cavity is kept near the second target temperature value, thereby preventing the temperatures in the first cavity and the second cavity from being too high and shortening the amplitude of the temperature change.

[0080] It can be understood that since at least two heating parts supply heat to the first cavity and the second cavity respectively, the temperature in the first cavity and the temperature in the second cavity will affect each other. The present application can determine the first on-off ratio corresponding to the first cavity and the second on-off ratio corresponding to the second cavity based on the first target temperature value and the second target temperature value, so that the first on-off ratio and the second on-off ratio are both associated with the first target temperature value and the second target temperature value. That is, after the first cavity is heated to the first target temperature value and the second cavity is heated to the second target temperature value, at least two heating parts are controlled to operate at the on-off ratio associated with the first target temperature value and the second target temperature value, so that the temperature in the first cavity and the temperature in the second cavity can be coordinated with each other, avoiding ignoring the influence of the other cavity when controlling one cavity alone, so that the first cavity and the second cavity are both near the target temperature, avoiding the situation where the temperature in the first cavity and the temperature in the second cavity fluctuate too much.

[0081] In a specific application, the temperature rise process in the first cavity and the second cavity includes a temperature rise period and a constant temperature period. In the temperature rise period, at least two heating units are both turned on, so that the temperature in the first cavity is rapidly raised to a first target temperature value, and the temperature in the second cavity is rapidly raised to a second target temperature value. In the constant temperature period, the first on-off ratio and the second on-off ratio are determined based on the first target temperature value and the second target temperature value, so that the temperature in the first cavity is maintained near the first target temperature value, and the temperature in the second cavity is maintained near the second target temperature value, thereby preventing excessive temperature fluctuations in the first cavity and the second cavity.

[0082] It should be noted that after the temperature in the first cavity and the temperature in the second cavity reach the corresponding target temperature, the heating part is controlled to heat for a period of time and then turn off for a period of time, and so on and so forth, so that the heating part has a ratio of power-on time to power-off time in each power-on and power-off cycle. The first on-off ratio is the ratio of the power-on time to the power-off time of the heating part corresponding to the first cavity, and the second on-off ratio is the ratio of the power-on time to the power-off time of the heating part corresponding to the second cavity.

[0083] In some embodiments, exemplarily, the control unit 603 determines the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value, including: when the first target temperature value is greater than the second target temperature value, determining the first preset on-off ratio of the heating part corresponding to the first cavity according to the first temperature value and the first target temperature value, and determining the first on-off ratio as the first preset on-off ratio; determining the second preset on-off ratio of the heating part corresponding to the second cavity according to the second temperature value and the second target temperature value; determining the average on-off ratio according to the first target temperature value and the second target temperature value; when the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, determining the second on-off ratio as the difference between the average on-off ratio and the first preset on-off ratio.

[0084] In this embodiment, the step of determining the first on-off ratio of the heating part corresponding to the first cavity and the second on-off ratio of the heating part corresponding to the second cavity according to the first target temperature value and the second target temperature value specifically includes: comparing the first target temperature value and the second target temperature value, and when the first target temperature value is greater than the second target temperature value, first controlling the first cavity with a higher temperature requirement so that the heating part of the first cavity operates at a first preset on-off ratio determined according to the first target temperature value and the first temperature value, that is, using the first preset on-off ratio as the first on-off ratio, so that the heating part intermittently heats the first cavity, thereby maintaining the temperature in the first cavity near the first target temperature value. Then, the second preset on-off ratio corresponding to the heating part of the second cavity is determined according to the second temperature value and the second target temperature value in the second cavity. Since the temperature in the first cavity affects the second cavity, the operation of the heating part corresponding to the second cavity is not controlled according to the second preset on-off ratio at this time. For example, the average on-off ratio between the two can be determined according to the first target temperature value and the second target temperature value. When the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, the difference between the average on-off ratio and the first preset on-off ratio is used as the second on-off ratio, and then the heating part corresponding to the second cavity is controlled according to the second on-off ratio to balance the influence of the temperature of the first cavity on the second cavity, avoid the temperature of the second cavity from fluctuating, and maintain the temperature stability in the second cavity.

[0085] Exemplarily, when the sum of the first preset on-off ratio and the second preset on-off ratio is smaller than the average on-off ratio, the second on-off ratio is determined to be the second preset on-off ratio.

[0086] In some embodiments, exemplarily, the control unit 603 is also used to: when the second temperature value is greater than or equal to the sum of the second target temperature value and the first threshold value, control the heating part corresponding to the second cavity to be turned off; when the second temperature value is less than or equal to the difference between the second target temperature value and the first threshold value, control the heating part corresponding to the second cavity to operate at a third preset on-off ratio.

[0087] In this embodiment, the control unit 603 is also used to: when the second temperature value in the second cavity is greater than or equal to the sum of the second target temperature value and the first threshold value, the temperature in the second cavity is higher, and at this time, the heating part corresponding to the second cavity is turned off, so that the temperature in the second cavity gradually decreases to the second target temperature value; when the second temperature value in the second cavity is less than or equal to the difference between the second target temperature value and the first threshold value, it means that the difference between the second temperature value in the second cavity and the second target temperature value is large, and at this time, the heating part corresponding to the second cavity is controlled to operate at a third preset on-off ratio, so that the temperature in the second cavity quickly rises to the second target temperature value, and then when the temperature in the second cavity is controlled by the first target temperature value and the second target temperature value, the temperature in the second cavity is avoided from being too high or too low.

[0088] In a specific application, the first threshold is set according to actual conditions. For example, the first threshold is greater than or equal to 2° C. and less than or equal to 5° C. For example, the first threshold is equal to 3° C.

[0089] Exemplarily, in this embodiment, in the constant temperature section, when the second temperature value in the second cavity is greater than the difference between the second target temperature value and the first threshold value, and less than the sum of the second target temperature value and the first threshold value, the second on-off ratio is controlled to be the difference between the average on-off ratio and the first preset on-off ratio.

[0090] In some embodiments, for example, when the second target temperature value is greater than the first target temperature value, the second preset on-off ratio is determined based on the second temperature value and the second target temperature value, and the second on-off ratio is determined to be the second preset on-off ratio; the first preset on-off ratio of the heating part corresponding to the first cavity is determined based on the first temperature value and the first target temperature value; when the sum of the first preset on-off ratio and the second preset on-off ratio is greater than or equal to the average on-off ratio, the first on-off ratio is determined to be the difference between the average on-off ratio and the second preset on-off ratio.

[0091] In this embodiment, when the second target temperature value is greater than the first target temperature value, the target temperature corresponding to the second cavity is higher. In this case, the heating unit corresponding to the second cavity is controlled to operate at a second preset on-off ratio determined based on the second target temperature value and the second temperature value. That is, the second preset on-off ratio is set to the second on-off ratio, so that the temperature in the second cavity is maintained near the second target temperature value. At the same time, the first preset on-off ratio of the heating unit corresponding to the first cavity is determined based on the first temperature value and the first target temperature value. If the sum of the first preset on-off ratio and the second preset on-off ratio is greater than the average on-off ratio, it means that the second preset on-off ratio is higher. In this case, the first on-off ratio is determined as the difference between the average on-off ratio and the second preset on-off ratio, thereby ensuring that the temperature in the first cavity is not too high or too low, while balancing the impact of the higher temperature of the second cavity on the first cavity.

[0092] Exemplarily, when the sum of the first preset on-off ratio and the second preset on-off ratio is smaller than the average on-off ratio, the first on-off ratio is determined to be the first preset on-off ratio.

[0093] In some embodiments, for example, when the first temperature value is greater than or equal to the sum of the first target temperature value and the second threshold value, the heating part corresponding to the first cavity is controlled to be turned off; when the first temperature value is less than or equal to the difference between the first target temperature value and the second threshold value, the heating part corresponding to the first cavity is controlled to operate at a fourth preset on-off ratio.

[0094] In this embodiment, when the first temperature value is greater than or equal to the sum of the first target temperature value and the second threshold value, it means that the temperature in the first cavity is high. At this time, the heating part corresponding to the first cavity is turned off, so that the temperature in the first cavity is reduced, thereby avoiding the occurrence of burnt food due to high-temperature baking; when the first temperature value is less than or equal to the difference between the first target temperature value and the second threshold value, it means that the temperature in the first cavity is low. At this time, the heating part corresponding to the first cavity is controlled to operate at a fourth preset on-off ratio, thereby causing the temperature in the first cavity to rise rapidly, thereby avoiding the first cavity being at a low temperature for a long time and affecting the cooking process.

[0095] In a specific application, the second threshold is set according to actual conditions. For example, the second threshold is greater than or equal to 2° C. and less than or equal to 5° C. For example, the second threshold is equal to 3° C.

[0096] Exemplarily, in this embodiment, in the constant temperature section, when the first temperature value in the first cavity is greater than the difference between the first target temperature value and the second threshold value, and less than the sum of the first target temperature value and the second threshold value, the first on-off ratio is controlled to be the difference between the average on-off ratio and the second preset on-off ratio.

[0097] In some embodiments, exemplarily, the control unit 603 determines the first preset on-off ratio of the heating part corresponding to the first cavity according to the first temperature value and the first target temperature value, including: determining the first preset on-off ratio through a PID algorithm according to the first temperature value and the first target temperature value; the step of determining the second preset on-off ratio of the heating part corresponding to the second cavity according to the second temperature value and the second target temperature value, including: determining the second preset on-off ratio through a PID algorithm according to the second temperature value and the second target temperature value; the step of determining the average on-off ratio according to the first target temperature value and the second target temperature value, including: determining the corresponding average on-off ratio according to the average value of the first target temperature value and the second target temperature value.

[0098] In this embodiment, determining a first preset on-off ratio for a heating unit corresponding to a first cavity based on a first temperature value and a first target temperature value specifically includes determining the first preset on-off ratio based on the first temperature value and the first target temperature value using a PID algorithm, such that when the heating unit operates according to the first preset on-off ratio, the temperature in the first cavity is maintained near the first target temperature value. Determining a second preset on-off ratio for a heating unit corresponding to a second cavity based on a second temperature value and a second target temperature value includes determining the second preset on-off ratio based on the second temperature value and the second target temperature value using a PID algorithm, such that when the heating unit provides heat to the second cavity at the second preset on-off ratio, the temperature in the second cavity is maintained near the second target temperature value. Determining an average on-off ratio based on the first target temperature value and the second target temperature value specifically includes determining the corresponding average on-off ratio based on the average of the sum of the first target temperature value and the second target temperature value, thereby finding a balance point between the target temperatures of the first and second cavities.

[0099] It can be understood that the PID algorithm is: a basic form of digital PID control algorithm, which is a control algorithm that performs PID control by increasing the control quantity (the difference between the current control quantity and the previous control quantity).

[0100] For example, in the setting, the average on-off ratio corresponding to the average value of the sum of the first target temperature value and the second target temperature value can be obtained by basic table lookup.

[0101] For example, a table of average on-off ratios corresponding to an average value of the sum of the first target temperature value and the second target temperature value may be stored in advance in the cooking appliance.

[0102] According to one embodiment of the present application, a cooking appliance 1 is also proposed, comprising: a first cavity 20; a second cavity 22; at least two heating parts 4, at least two heating parts 4 being used to provide heat to the first cavity 20 and the second cavity 22 respectively; and a control device as proposed in the second aspect.

[0103] As shown in FIG4 , the cooking device 1 provided herein includes a first cavity 20, a second cavity 22, and at least two heating units 4. The at least two heating units 4 are respectively configured to heat the first cavity 20 and the second cavity 22, thereby enabling separate cooking of ingredients within the first and second cavities 20, 22. This allows the simultaneous cooking of different types of ingredients using the same cooking device 1, thereby improving cooking efficiency. Furthermore, the control device can determine, based on the first and second target temperature values, a first on-off ratio and a second on-off ratio corresponding to the at least two heating units 4 when the first temperature within the first cavity 20 is greater than or equal to the first target temperature and the second temperature is greater than or equal to the second target temperature. Consequently, under the mutual influence of the first and second cavities 20, 22, the first cavity 20 and the second cavity 22 are maintained near the first target temperature, and the second cavity 22 is maintained near the second target temperature, thereby preventing the temperatures within the first and second cavities 20, 22 from becoming excessively high and shortening the temperature fluctuations.

[0104] In some embodiments, illustratively, the cooking utensil 1 further includes: a shell 2; a partition 3, the partition 3 is arranged in the shell 2, and the partition 3 divides the shell 2 into at least a first cavity 20 and a second cavity 22; wherein, one of the first cavity 20 and the second cavity 22 is located on the top of the other, or one of the first cavity 20 and the second cavity 22 is located on one side of the other.

[0105] In this embodiment, the cooking appliance 1 also includes a shell 2 and a partition 3, which is arranged in the shell 2, thereby dividing the space in the shell 2 into a first cavity 20 and a second cavity 22. Exemplarily, the first cavity 20 and the second cavity 22 are distributed in a vertical direction, so that one of the first cavity 20 and the second cavity 22 is located on top of the other, or the first cavity 20 and the second cavity 22 are distributed in a horizontal direction, so that one of the first cavity 20 and the second cavity 22 is located on one side of the other.

[0106] Exemplarily, the partition 3 is detachably connected to the shell 2 so that the space inside the shell 2 can be switched into a large cavity, which is convenient for cooking larger ingredients.

[0107] Exemplarily, the cooking appliance 1 further includes at least two temperature sensors 5 , which are respectively disposed in the first cavity 20 and the second cavity 22 for detecting the temperatures in the first cavity 20 and the second cavity 22 .

[0108] For example, Figure 4 shows the cavity device distribution diagram. The central partition 3 can be a baking tray or a partition that divides the cavity. Cooking appliance 1 also includes two upper and lower NTC (Negative Temperature Coefficient) temperature sensors 5. For example, cooking appliance 1 includes any of an oven, air fryer oven, microwave oven, microwave air fryer, and the like.

[0109] As shown in Figure 6, according to one embodiment of the present application, an electronic device 7 is also proposed, including: a processor 702 and a memory 704, the memory 704 stores programs or instructions that can be run on the processor 702, and when the programs or instructions are executed by the processor 702, the steps of the control method of the cooking appliance proposed in any of the above items are implemented.

[0110] The electronic device 7 provided in the present application has all the beneficial effects of the cooking appliance control method because it has the steps of any of the above-mentioned cooking appliance control methods.

[0111] According to one embodiment of the present application, a readable storage medium is further provided, on which a program or instruction is stored. When the program or instruction is executed by a processor, the steps of any of the above-mentioned methods for controlling a cooking appliance are performed.

[0112] The readable storage medium provided by the present application has the steps of any of the above-mentioned cooking appliance control methods, and therefore has all the beneficial effects of the cooking appliance control method.

[0113] In specific applications, the first cavity and the second cavity are arranged in an upper and lower position. Figure 2 is a temperature control logic diagram of the dual PID with independent upper and lower temperature control. The overall temperature control is divided into a temperature rise section (for example, the part shown in B) and a constant temperature section (for example, the part shown in C). A1 is the temperature rise curve of the first cavity, and A2 is the temperature rise area of ​​the second cavity. The temperature control logic of the temperature rise section is that the upper and lower tubes (for example, at least two heating parts) are fully open until the temperatures of the upper and lower cavities (for example, the first cavity and the second cavity) reach the target temperatures T1 (for example, the first target temperature) and T2 (for example, the second target temperature). After reaching the constant temperature section, the temperature is controlled according to the target temperature.

[0114] Figure 3 is the interaction logic diagram of the cooking appliance proposed in this application, which is a specific dual-PID control method. After setting the target temperatures T1 and T2 of the upper and lower cavities, when T1>T2, the target temperature of the upper cavity is higher than that of the lower cavity. First, the algorithm calculates PWM1 (the on-off time of the barbecue tube, such as the first preset on-off ratio) through the PID algorithm based on the difference between the temperature of the upper temperature sensor (such as the temperature sensor corresponding to the first cavity) and the target temperature (such as T1). Similarly, PWM2 (such as the second preset on-off ratio) is calculated from the lower temperature sensor (such as the temperature sensor corresponding to the second cavity) and the target temperature (such as T2). In addition, in the setting, the mapping relationship corresponding to (T1+T2) / 2 is obtained through basic look-up table to get PWM (such as the average on-off ratio). If PWM1+PWM2≥PWM, then PWM2 = PWM - PWM1. If the temperature of the lower cavity ≥ T2+3, then PWM2 = 0. If the temperature of the lower cavity ≤ T2-3, then PWM2 = 30. When T1<T2, the control logic is reversed. Exemplarily, when T1<T2, the target temperature of the upper cavity is lower than that of the lower cavity. First, the algorithm calculates PWM2 (the on-off time of the barbecue tube, such as the second preset on-off ratio) through the PID algorithm based on the difference between the temperature of the lower temperature sensor (such as the temperature sensor corresponding to the second cavity) and the target temperature (such as T2). Similarly, PWM1 (such as the first preset on-off ratio) is calculated from the upper temperature sensor (such as the temperature sensor corresponding to the first cavity) and the target temperature (such as T1). In addition, in the setting, the mapping relationship corresponding to (T1+T2) / 2 is obtained through basic look-up table to get PWM (such as the average on-off ratio). If PWM1+PWM2≥PWM, then PWM1 = PWM - PWM2. If the temperature of the upper cavity ≥ T1+3, then PWM1 = 0. If the temperature of the upper cavity ≤ T1-3, then PWM1 = 30. This control method first controls the cavity with the higher set target temperature, and then controls the temperature of the lower cavity according to the performance of the cavity itself.

[0115] For example: The user wants to bake 2 kinds of ingredients in the oven. The lower cavity is set to bake sweet potatoes at 200°C with hot air, and the upper cavity is set to bake steak at 230°C with hot air.
