Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and more specifically, to a cooking appliance, a method for controlling the cooking appliance, a device, and a storage medium. Background Technology

[0002] In related technologies, microwave ovens can only fry one type of food at a time, and cannot fry multiple types of food in separate sections, which reduces the user experience. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the related art.

[0004] Therefore, the first aspect of this application is to propose a cooking utensil.

[0005] The second aspect of this application is to propose a method for controlling a cooking appliance.

[0006] The third aspect of this application is to provide a control device for a cooking appliance.

[0007] The fourth aspect of this application is to provide a control device for a cooking appliance.

[0008] The fifth aspect of this application is to propose a readable storage medium.

[0009] The sixth aspect of this application is to propose a cooking utensil.

[0010] In view of this, according to one aspect of this application, a cooking appliance is proposed, comprising: a housing, the housing including a cooking cavity; a holding portion disposed within the cooking cavity for holding food; and a microwave heating portion disposed within the housing, wherein the microwave outlet of the microwave heating portion is movable relative to the holding portion to emit microwaves toward different positions of the holding portion, such that different areas of the holding portion have different heating rates.

[0011] The cooking appliance provided by this invention includes a housing with a cooking cavity inside. The housing houses other components of the cooking appliance, protecting them from direct exposure to the external environment and preventing impacts from external objects, thus extending the lifespan of the components. Furthermore, the cooking cavity is located within the housing to ensure that food is cooked inside the appliance, preventing contamination from the external environment.

[0012] Furthermore, the cooking appliance also includes a holding part, which is detachably installed inside the cooking cavity. The holding part is used to hold food. Before cooking, the holding part can be removed from the cooking cavity, the food can be placed on the holding part, and then the holding part can be placed back into the cooking cavity. After cooking, the holding part can be removed again, which facilitates the handling of food. Users do not need to directly contact the food, thus avoiding any impact on the cooking effect and preventing users from directly contacting the food.

[0013] Furthermore, the cooking appliance also includes a microwave heating element, which generates microwaves and sends microwaves into the cooking cavity, thereby heating the food inside the cooking cavity using microwaves.

[0014] Furthermore, the holding section can heat up upon receiving microwaves emitted by the microwave heating section, enabling the food to be pan-fried from a higher position within the holding section, thus realizing the pan-frying function of the cooking appliance. Moreover, the outlet of the microwave heating section can move relative to the holding section, allowing the microwaves emitted by the holding section to be directed towards different positions within the holding section. This results in varying amounts of microwaves received at different locations within the holding section, leading to different heating rates at different locations. In other words, when pan-frying food using the holding section, different ingredients can be placed in different areas of the holding section. Then, based on the cooking requirements of different ingredients, the microwave outlet of the microwave heating section can be moved to the corresponding position, ensuring that the heating rate of different areas of the holding section matches the cooking requirements of the ingredients. This achieves simultaneous heating of different ingredients in different areas while ensuring the cooking effect of different ingredients, thus realizing zoned heating of the cooking appliance. This further expands the functionality of the cooking appliance beyond its pan-frying function, enhancing the user experience.

[0015] It is understandable that the holding section can include multiple different holding areas, each used to hold different ingredients. During cooking, the closer the microwave outlet of the microwave heating element is to a holding area, the more microwaves that area receives, resulting in faster heating. Conversely, the farther the microwave outlet is from a holding area, the less microwaves that area receives, leading to slower heating. Therefore, when cooking different types and / or quantities of ingredients simultaneously, the position of the microwave outlet can be adjusted according to the required heating rate of each ingredient to ensure optimal cooking results. When the microwave outlet is located between two adjacent holding areas, the amount of microwaves received by both areas is equal, resulting in the same heating rate for both areas.

[0016] The cooking appliance provided by this invention, through the setting of a microwave heating unit, enables the heating and cooking of food using microwaves. Simultaneously, by placing food in the serving dish, the food can be heated by absorbing microwaves emitted by the microwave heating unit, and can also be pan-fried, thus realizing the pan-frying function of the cooking appliance. Furthermore, by setting the microwave outlet of the microwave heating unit to be movable relative to the serving section, the microwave outlet can emit microwaves towards different positions of the serving section, resulting in different amounts of microwaves received at different positions of the serving section. Consequently, different positions of the serving section will have different heating rates. When frying food through the serving section, different foods can be placed in different areas of the serving section. Then, according to the cooking requirements of different foods, the microwave outlet of the microwave heating unit can be moved to the corresponding position so that the heating rate of different areas of the serving section with different foods can match the cooking requirements of the foods. This achieves simultaneous heating of different foods in different areas while ensuring the cooking effect of different foods. In other words, it realizes the zoned heating of the cooking appliance. Based on the frying function of the cooking appliance, it further expands the function of the cooking appliance and improves the user experience.

[0017] Furthermore, the cooking appliance proposed according to the above-described technical solution of the present invention may also have the following additional technical features:

[0018] In the above technical solution, the holding part further includes: a holding tray, on one side of which is provided multiple holding areas; and multiple absorbing elements, which are respectively attached to the back of the multiple holding areas, and the multiple absorbing elements are used to absorb the microwaves generated by the microwave heating part.

[0019] In this technical solution, the serving part includes a serving plate for placing ingredients. The serving plate has multiple serving areas on one side, each of which can hold ingredients. This allows different ingredients to be placed in different serving areas when cooking different ingredients, preventing them from moving and mixing during cooking and ensuring the cooking effect of each ingredient.

[0020] Furthermore, the serving section also includes multiple microwave-absorbing components, the number of which is the same as the number of serving areas. Each microwave-absorbing component is positioned one-to-one with a serving area, and each component is attached to the serving tray and located on the back of its corresponding serving area. The microwave-absorbing components absorb the microwaves generated by the microwave heating unit. Simultaneously, the components heat up, thereby heating the corresponding serving area and cooking the food within that area during the heating process.

[0021] It is understandable that during the operation of the microwave heating section, the closer the microwave outlet is to the absorbing element, the more microwaves the absorbing element absorbs. Therefore, the absorbing element heats up faster than the absorbing element that is farther away from the microwave outlet, and thus the heating rate of the holding area is faster.

[0022] In any of the above technical solutions, the holding part further includes: a shielding component disposed between two adjacent absorbing components, the shielding component being used to shield microwave conduction between the two adjacent absorbing components.

[0023] In this technical solution, the holding part also includes a shielding component, which is disposed between two adjacent absorbing components. By setting the shielding component, the microwaves between the two adjacent absorbing components can be shielded, avoiding interference between the microwaves of the two adjacent holding areas, thereby ensuring the temperature change effect of the two adjacent holding areas, and thus ensuring the effect of zoned heating.

[0024] In any of the above technical solutions, the microwave heating unit further includes: a magnetron disposed within the housing for generating microwaves; a waveguide whose inlet is connected to the magnetron and is used to guide the microwaves generated by the magnetron into the cooking cavity; wherein the waveguide is movable relative to the serving section, and emits microwaves toward different positions of the serving section with the outlet of the waveguide.

[0025] In this technical solution, the microwave heating unit includes a magnetron, which generates microwaves when connected to a power source. This allows the microwave heating unit to generate microwaves to heat the food inside the cooking cavity, and for the microwave-absorbing components in the serving section to absorb the microwaves, enabling the serving section to fry the food. Specifically, the magnetron is disposed inside the housing of the cooking appliance and located outside the cooking cavity.

[0026] Furthermore, the microwave heating unit also includes a waveguide, which guides the direction of microwave transmission generated by the magnetron, i.e., directs the microwaves to the corresponding positions. Specifically, the inlet of the waveguide is connected to the magnetron. Simultaneously with the magnetron generating microwaves, the microwaves enter the waveguide through the inlet and are then exited from the outlet to the corresponding positions. Furthermore, the outlet of the waveguide can move relative to the holding unit, allowing the microwaves emitted by the microwave holding unit to be directed towards different positions within the holding unit under the guidance of the waveguide. This results in different amounts of microwaves received at different positions within the holding unit, and consequently, different heating rates at different positions within the holding unit.

[0027] In any of the above technical solutions, the cooking appliance further includes: an image acquisition unit disposed inside the cooking cavity, used to acquire image information of the serving portion and the food inside the cooking cavity; and a controller connected to the image acquisition unit and the microwave heating unit respectively, used to control the heating position of the microwave heating unit according to the image information.

[0028] In this technical solution, the cooking appliance also includes an image acquisition unit and a controller. The image acquisition unit is used to acquire image information inside the cooking cavity and is connected to the controller. Therefore, the image acquisition unit can transmit the acquired image inside the cooking cavity to the controller. The controller is also connected to the microwave heating unit, so that the controller can control the operation of the microwave heating unit according to the image information inside the cooking cavity acquired by the image acquisition unit. This further improves the automation level of the cooking appliance, facilitates user operation, and enhances the user experience.

[0029] Specifically, by acquiring image information of the cooking cavity through the image acquisition unit, the controller can determine whether there is a container in the cooking cavity. If there is no container in the cooking cavity, it can be determined that the cooking appliance will operate in normal mode, that is, the food will be heated directly by the microwave generated by the microwave heating unit. At this time, the outlet of the microwave heating unit can be kept in the initial position. The controller controls the operation of the microwave heating unit to achieve direct heating of the food by microwave.

[0030] If a serving area is placed inside the cooking cavity, it can be determined that the current cooking appliance will fry the food through the serving area, which is the frying mode of the cooking appliance. At this time, the controller also needs to determine the type and weight of the food in different serving areas on the serving area through image information, and then determine the heating temperature required for each serving area. Finally, the controller determines the outlet position of the waveguide of the microwave heating unit according to the different heating temperatures of different serving areas. After adjusting the outlet position of the waveguide, the controller can control the operation of the microwave heating unit to achieve regional cooking of different foods.

[0031] In addition, in the frying mode of the cooking appliance, users can also manually input different heating temperatures required for different serving areas. After receiving the heating temperature input by the user, the controller controls the outlet position of the waveguide according to the heating temperature, and then controls the operation of the microwave heating unit to perform zoned cooking.

[0032] According to a second aspect of this application, a control method for a cooking appliance is proposed. This control method can be used for any of the cooking appliances described in the above-mentioned technical solutions. The control method includes: acquiring a first target heating temperature and a second target heating temperature of two adjacent serving areas on the serving section; determining a first target position based on the first target heating temperature and the second target heating temperature; controlling the microwave heating section to move to the first target position; and controlling the microwave heating section to operate based on the microwave heating section being located at the first target position.

[0033] The control method for cooking appliances provided by the present invention can be used in any of the cooking appliances described in the above technical solutions. The cooking appliance includes a cooking cavity and a holding part. The holding part includes different holding areas for placing food ingredients. The cooking appliance also includes a microwave heating part. The microwave outlet of the microwave heating part can move relative to the holding part to emit microwaves toward different positions of the holding part, so that different areas of the holding part have different heating rates.

[0034] Specifically, during the operation of the cooking appliance, firstly, the first target heating temperature and the second target heating temperature of two adjacent serving areas on the serving section are obtained. It can be understood that at this time, the user needs to fry different ingredients using the frying function of the cooking appliance. The user can put two different ingredients into the two adjacent serving areas respectively, and then set different target heating temperatures for the two serving areas according to the different ingredients, namely the first target heating temperature and the second target heating temperature.

[0035] Then, the first target position of the microwave outlet of the microwave heating unit is determined according to the first target heating temperature and the second target heating temperature. Specifically, when the first target heating temperature is greater than the second target heating temperature, the first target position is located near the holding area corresponding to the first target heating temperature, so that the heating rate of the holding area is greater than that of the other holding area, thereby meeting the cooking requirements of the food held in the holding area, and also meeting the cooking cavity requirements of the food in the other holding area.

[0036] Furthermore, by controlling the microwave outlet of the microwave heating unit to move to the first target position, and then controlling the operation of the microwave heating unit, it is possible to achieve zoned heating of two different ingredients.

[0037] The control method for cooking appliances provided by this invention obtains different heating temperatures for different serving areas, namely a first target heating temperature and a second target heating temperature. Based on these temperatures, a first target position of the microwave outlet of the microwave heating unit is determined. The microwave heating unit is then moved so that the microwave outlet is positioned at the first target position. This allows the microwave outlet to be moved to the appropriate position according to the cooking requirements of different ingredients, ensuring that the heating rate of different areas of the serving area matches the cooking requirements of the ingredients. Furthermore, this method achieves simultaneous heating of different ingredients in different areas while maintaining optimal cooking results. In other words, it enables zoned heating of the cooking appliance, further expanding its functionality beyond its frying function and improving the user experience.

[0038] In any of the above technical solutions, the control method of the cooking appliance further includes: acquiring a first target heating time and a second target heating time for two adjacent serving areas respectively; controlling the microwave heating unit to move from a first target position to a second target position based on the first target heating time; and controlling the microwave heating unit to stop operating based on the second target heating time; wherein, when the first target heating time is less than the second target heating time, and the microwave heating unit is located at the second target position, the microwave outlet is opposite to the serving area corresponding to the second target heating time.

[0039] In this technical solution, the first target heating time and the second heating time of two adjacent serving areas can also be obtained, which are the different heating times required for different ingredients. Thus, in addition to achieving different heating temperatures for different ingredients, different ingredients on the serving section can be heated according to different heating times, further ensuring the cooking effect of different ingredients and improving the user experience.

[0040] Specifically, the first target heating time is shorter than the second target heating time. After the microwave outlet of the microwave heating unit moves to the first target position, the microwave heating unit is controlled to operate, thereby heating the two adjacent serving areas. Simultaneously, a timer starts. When the microwave heating unit continues operating until the first target heating time has elapsed, it indicates that the food corresponding to the first target heating time has been cooked. At this point, the microwave heating unit can be controlled to move from the first target position to the second target position. When the microwave heating unit is at the second target position, the microwave outlet is opposite the serving area corresponding to the second target heating time. Specifically, at this point, the distance between the microwave outlet and this serving area is the shortest, and the distance to the adjacent serving area is the longest. In other words, when the food corresponding to the first target heating time has been cooked, there is no need to heat that serving area further. Therefore, there is no need to keep the microwave outlet at the first target position; instead, the microwave outlet is moved to the second target position to cook the remaining food separately, thus avoiding energy waste, improving heating efficiency, and enhancing the user experience.

[0041] In any of the above technical solutions, the step of determining the first target position based on the first target heating temperature and the second target heating temperature further includes: determining, based on the first target heating temperature and the second target heating temperature, the target holding area facing the microwave outlet when the microwave heating unit is located at the first target position; determining, based on a preset formula, the distance between the microwave outlet and the center line of the connection between two adjacent holding areas when the microwave heating unit is located at the first target position; and determining the first target position based on the target holding area and the distance between the microwave outlet and the center line; wherein the preset formula is: L is the distance between the microwave outlet and the centerline, T is a constant, T1 is the higher of the first target heating temperature and the second target heating temperature, T2 is the lower of the first target heating temperature and the second target heating temperature, and S is the maximum distance between the microwave outlet and the centerline when the microwave heating outlet is opposite to the holding area corresponding to the higher of the first target heating temperature and the second target heating temperature.

[0042] In this technical solution, the first target position of the microwave heating unit can be determined based on a first target heating temperature and a second target heating temperature, and in the following manner. First, the container area facing the microwave outlet is determined based on the first target heating temperature and the second target heating temperature. Specifically, when the first target heating temperature is greater than the second target heating temperature, it can be determined that when the microwave heating unit is located at the first target position, the microwave outlet faces the container area corresponding to the first target heating temperature. Conversely, when the first target heating temperature is less than the second target heating temperature, it can be determined that when the microwave heating unit is located at the first target position, the microwave outlet faces the container area corresponding to the second target heating temperature. In other words, when the microwave heating unit is located at the first target position, the microwave outlet faces the container area corresponding to the higher target heating temperature, thereby making the heating rate of the container area faster to ensure that the target temperature can be reached quickly.

[0043] Furthermore, after determining the holding area facing the microwave outlet, the distance between the microwave outlet and the center line of the connection between the two adjacent holding areas can be calculated using a preset formula based on the specific values ​​of the first target heating temperature and the second target heating temperature. After determining the orientation of the microwave outlet and the distance between the microwave outlet and the center line, the first target position can be determined.

[0044] Specifically, the preset formula is: Where L is the distance between the microwave outlet and the centerline, T is a constant that can be set according to the rated power of the cooking appliance or other fixed parameters of the cooking appliance. T1 is the higher of the first target heating temperature and the second target heating temperature, T2 is the lower of the first target heating temperature and the second target heating temperature, and S is the maximum distance between the microwave heating outlet and the centerline when the microwave heating outlet is opposite to the serving area corresponding to the higher of the first target heating temperature and the second target heating temperature.

[0045] In any of the above technical solutions, before the step of obtaining the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section, the method further includes: receiving a preheating command input by the user; determining the first preheating temperature and the second preheating temperature of two adjacent holding areas on the holding section according to the preheating command; determining a third target position according to the first preheating temperature and the second preheating temperature; controlling the microwave heating section to move to the third target position; and controlling the microwave heating section to operate based on the microwave heating section being located at the third target position.

[0046] In this technical solution, before frying the food on the serving section, the cooking cavity can be preheated according to the cooking requirements of the food. That is, before obtaining the first target heating temperature and the second target heating temperature of two adjacent serving areas on the serving section, the two adjacent serving areas of the serving section are preheated.

[0047] Specifically, the system receives a preheating command input by the user. This command can include different preheating temperatures for two serving areas. It's understood that the user needs to fry different ingredients using the cooking appliance's frying function; therefore, the serving areas for the two different ingredients also require different preheating temperatures—a first preheating temperature and a second preheating temperature. Then, based on the first and second preheating temperatures, a third target position for the microwave outlet of the microwave heating unit is determined. Specifically, when the first preheating temperature is higher than the second preheating temperature, the third target position is located closer to the serving area corresponding to the first preheating temperature. This ensures that the heating rate of the first serving area is greater than that of the other serving area, thus meeting the cooking requirements of the ingredients in the first serving area while also satisfying the second preheating temperature requirement of the other serving area. Further, the microwave outlet of the microwave heating unit is moved to the third target position, and then the microwave heating unit is controlled to operate, thus achieving preheating of both serving areas.

[0048] In any of the above technical solutions, further, after the step of controlling the operation of the microwave heating unit based on the microwave heating unit being located at the third target position, the method further includes: obtaining the first actual temperature and the second actual temperature of two adjacent holding areas; controlling the microwave heating unit to move from the third target position to the fourth target position based on the first actual temperature reaching the first preheating temperature; and stopping the operation of the controlled microwave heating unit based on the second actual temperature reaching the second preheating temperature; wherein, the first preheating temperature is lower than the second preheating temperature, the first actual temperature is lower than the second actual temperature, and when the microwave heating unit is located at the fourth target position, the microwave outlet of the microwave heating unit is opposite to the holding area in the two holding areas corresponding to the second preheating temperature.

[0049] In this technical solution, during the preheating process of the cooking cavity, after the microwave heating unit moves to the third target position and starts operating, the first and second actual temperatures of the two adjacent serving areas can be obtained in real time. Then, the microwave heating unit is controlled according to the first and second actual temperatures. That is, when the two serving areas reach the corresponding first and second actual temperatures, the heating of the serving area can be stopped, which can save energy and improve the preheating efficiency.

[0050] Specifically, the first preheating temperature is lower than the second preheating temperature, and the first actual temperature is lower than the second actual temperature. During the operation of the microwave heating unit, when the first actual temperature of the holding area corresponding to the first preheating temperature reaches the first preheating temperature, the preheating of the holding area is completed. At this time, the microwave heating unit can be controlled to move from the third target position to the fourth target position. When the microwave heating unit is located at the fourth target position, the microwave outlet is opposite to the holding area corresponding to the second preheating temperature. Specifically, at this time, the distance between the microwave outlet and the holding area is the shortest, and the distance to the adjacent holding area is the longest. That is to say, when the holding area corresponding to the first preheating temperature has been preheated, there is no need to heat the holding area. Therefore, there is no need to keep the microwave outlet at the third target position. Instead, the microwave outlet is moved to the fourth target position to heat the holding area that has not been preheated, thereby avoiding energy waste, improving preheating efficiency, and improving user experience.

[0051] Furthermore, the third target position of the microwave heating unit can be determined based on the first preheating temperature and the second preheating temperature, and in the following manner. First, the holding area facing the microwave outlet is determined based on the first preheating temperature and the second preheating temperature. Specifically, when the first preheating temperature is greater than the second preheating temperature, it can be determined that when the microwave heating unit is located at the third target position, the microwave outlet faces the holding area corresponding to the first preheating temperature. Conversely, when the first preheating temperature is less than the second preheating temperature, it can be determined that when the microwave heating unit is located at the third target position, the microwave outlet faces the holding area corresponding to the second preheating temperature. In other words, when the microwave heating unit is located at the third target position, the microwave outlet faces the holding area corresponding to the higher preheating temperature, thereby making the heating rate of that holding area faster to ensure that the target temperature can be reached quickly.

[0052] Furthermore, after determining the holding area facing the microwave outlet, the specific values ​​of the first and second preheating temperatures can be used, through the aforementioned preset formula: When the microwave heating unit is located at the third target heating position, the distance between the microwave outlet and the center line of the connection between the two adjacent holding areas is calculated. After determining the orientation of the microwave outlet and the distance between the microwave outlet and the center line, the third target position can be determined.

[0053] In any of the above technical solutions, the step of obtaining the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section further includes: obtaining an image of the food on the holding section; and determining the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section based on the food image.

[0054] In this technical solution, an image acquisition unit can be used to acquire images of the food inside the cooking cavity. These images are then used to determine the type and weight of the food in different serving areas on the serving unit, and subsequently, to determine the required second and first target heating temperatures for two adjacent serving areas. By acquiring food images and determining the first and second target heating temperatures for the two serving areas based on these images, the need for manual input of the first and second target heating temperatures by the user is eliminated, further enhancing the intelligence of the cooking appliance and improving the user experience.

[0055] According to a third aspect of this application, a control device for a cooking appliance is provided, comprising: an acquisition unit for acquiring a first target heating temperature and a second target heating temperature of two adjacent serving areas on a serving section; a determination unit for determining a first target position based on the first target heating temperature and the second target heating temperature; and a control unit for controlling a microwave heating section to move to the first target position, and controlling the microwave heating section to operate based on the microwave heating section being located at the first target position.

[0056] The control device for the cooking appliance provided by this invention acquires different heating temperatures (i.e., a first target heating temperature and a second target heating temperature) for different serving areas through an acquisition unit. This allows a determining unit to determine a first target position of the microwave outlet of the microwave heating unit based on the first and second target heating temperatures. Then, the controller controls the microwave heating unit to move so that the microwave outlet is located at the first target position. This achieves the goal of moving the microwave outlet of the microwave heating unit to the corresponding position according to the cooking requirements of different ingredients, so that the heating rate of different areas of the serving area containing different ingredients can match the cooking requirements of the ingredients. This ensures the cooking effect of different ingredients while simultaneously heating them in different areas, thus achieving zoned heating of the cooking appliance. In addition to realizing the frying function of the cooking appliance, this further expands the functionality of the cooking appliance and improves the user experience.

[0057] Furthermore, the acquisition unit is also used to acquire the first target heating time and the second target heating time of two adjacent holding areas respectively; the control unit is also used to control the microwave heating unit to move from the first target position to the second target position based on the first target heating time of the microwave heating unit; and to control the microwave heating unit to stop operating based on the second target heating time of the microwave heating unit.

[0058] Wherein, the heating time of the first target is less than the heating time of the second target, and when the microwave heating part is located at the position of the second target, the microwave outlet is opposite to the holding area corresponding to the heating time of the second target.

[0059] Furthermore, the determining unit is specifically used to determine, based on the first target heating temperature and the second target heating temperature, the target holding area that the microwave outlet faces when the microwave heating unit is located at the first target position; to determine, based on a preset formula, the distance between the microwave outlet and the center line of the connection between two adjacent holding areas when the microwave heating unit is located at the first target position; and to determine the first target position based on the target holding area and the distance between the microwave outlet and the center line.

[0060] The preset formula is: L is the distance between the microwave outlet and the centerline, T is a constant, T1 is the higher of the first target heating temperature and the second target heating temperature, T2 is the lower of the first target heating temperature and the second target heating temperature, and S is the maximum distance between the microwave outlet and the centerline when the microwave heating outlet is opposite to the holding area corresponding to the higher of the first target heating temperature and the second target heating temperature.

[0061] Furthermore, the determining unit can also be used to receive a preheating command input by the user, and determine the first preheating temperature and the second preheating temperature of two adjacent holding areas on the holding section according to the preheating command; and determine the third target position according to the first preheating temperature and the second preheating temperature; the control unit can also be used to control the microwave heating section to move to the third target position; and control the microwave heating section to operate based on the microwave heating section being located at the third target position.

[0062] Furthermore, the acquisition unit can also be used to acquire the first actual temperature and the second actual temperature of two adjacent holding areas; the control unit can also be used to control the microwave heating part to move from the third target position to the fourth target position based on the first actual temperature reaching the first preheating temperature; and to control the microwave heating part to stop operating based on the second actual temperature reaching the second preheating temperature.

[0063] Wherein, the first preheating temperature is lower than the second preheating temperature, the first actual temperature is lower than the second actual temperature, and when the microwave heating part is located at the fourth target position, the microwave outlet of the microwave heating part is opposite to the holding area corresponding to the second preheating temperature in the two holding areas.

[0064] Furthermore, the acquisition unit is specifically used to acquire an image of the food on the serving section; and based on the food image, to determine a first target heating temperature and a second target heating temperature for two adjacent serving areas on the serving section.

[0065] According to the fourth aspect of this application, a control device for a cooking appliance is proposed, comprising: a processor and a memory, wherein the memory stores a program or instructions that can be executed on the processor, and when the program or instructions are executed by the processor, the steps of the control method for the cooking appliance as described in any of the above technical solutions are implemented.

[0082] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0083] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0084] The following is combined with Figures 1 to 9 The present application provides a detailed description of a cooking appliance, a control method for the cooking appliance, a device, and a storage medium through specific embodiments and application scenarios.

[0085] According to a first aspect of the invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a cooking appliance 100 is proposed, including a housing 102, the housing 102 including a cooking cavity 104; it also includes a holding part 106, which is disposed in the cooking cavity 104 for holding food; the cooking appliance 100 also includes a microwave heating part 108, and the microwave heating part 108 can be disposed inside the housing 102. The microwave outlet of the microwave heating part 108 can move relative to the holding part 106 to emit microwaves toward different positions of the holding part 106, so that different areas of the holding part 106 have different heating rates.

[0086] The cooking appliance 100 provided by the present invention includes a housing 102, within which a cooking cavity 104 is provided. The housing 102 houses other components of the cooking appliance 100, thereby protecting these components from direct exposure to the external environment and preventing them from being impacted by external objects, thus ensuring the service life of the components. Furthermore, the cooking cavity 104 is located within the housing 102 to ensure that food can be cooked inside the cooking appliance 100, preventing contamination from the external environment.

[0087] Furthermore, the cooking appliance 100 also includes a holding part 106, which is detachably disposed within the cooking cavity 104. The holding part 106 is used to hold food. Before cooking, the holding part 106 can be removed from the cooking cavity 104, the food can be placed on the holding part 106, and then the holding part 106 can be placed back into the cooking cavity 104. After cooking, the holding part 106 can be removed, which facilitates the handling of food. Users do not need to directly contact the food, thus avoiding any impact on the cooking effect and preventing direct contact between the user and the food.

[0088] Furthermore, the cooking appliance 100 also includes a microwave heating unit 108, which generates microwaves and sends microwaves into the cooking cavity 104, thereby heating the food in the cooking cavity 104 using microwaves.

[0089] Furthermore, the holding section 106 can also increase in temperature when it receives microwaves emitted by the microwave heating section 108, so as to fry the food by means of the high position of the holding section 106, thereby realizing the frying function of the cooking utensil 100.

[0090] Furthermore, the outlet of the microwave heating section 108 can move relative to the holding section 106, so that the microwaves emitted by the microwave holding section 106 can be emitted toward different positions of the holding section 106, thereby causing different amounts of microwaves to be received at different positions of the holding section 106, and consequently causing different heating rates at different positions of the holding section 106.

[0091] In other words, when frying food through the holding section 106, different foods can be placed in different areas of the holding section 106. Then, according to the cooking requirements of different foods, the microwave outlet of the microwave heating section 108 is moved to the corresponding position so that the heating rate of different areas of the holding section 106 where different foods are placed can match the cooking requirements of the foods. Thus, while achieving simultaneous heating of different foods through different areas, the cooking effect of different foods is guaranteed. That is, the cooking appliance 100 achieves zoned heating. Based on the frying function of the cooking appliance 100, the functions of the cooking appliance 100 are further expanded, and the user experience is improved.

[0092] It is understood that the holding section 106 can include multiple different holding areas, each used to hold different ingredients. During the operation of the cooking appliance 100, the closer the microwave outlet of the microwave heating section 108 is to a holding area, the more microwaves that area receives, resulting in a faster heating rate. Conversely, the farther the microwave outlet is from a holding area, the less microwaves that area receives, leading to a slower heating rate. Therefore, when cooking different types and / or quantities of ingredients simultaneously, the position of the microwave outlet can be adjusted according to the required heating rate of each ingredient to ensure optimal cooking results. When the microwave outlet is located between two adjacent holding areas, the amount of microwaves received by both areas is the same, resulting in the same heating rate for both areas.

[0093] The cooking appliance 100 provided by the present invention allows different ingredients to be placed in different areas of the holding section 106 when frying food. Then, according to the cooking requirements of different ingredients, the microwave outlet of the microwave heating section 108 is moved to the corresponding position so that the heating rate of different areas of the holding section 106 where different ingredients are placed can match the cooking requirements of the ingredients. Thus, while achieving simultaneous heating of different ingredients in different areas, the cooking effect of different ingredients is guaranteed. That is, the cooking appliance 100 achieves zoned heating. Based on the frying function of the cooking appliance 100, the functions of the cooking appliance 100 are further expanded, and the user experience is improved.

[0094] In the above embodiments, further, as Figure 2As shown, the holding section 106 includes a holding tray 110, and a plurality of holding areas 112 are provided on one side of the holding tray 110; the holding section 106 also includes a plurality of microwave absorbing elements 114, which are respectively attached to the back of the plurality of holding areas 112, and the plurality of microwave absorbing elements 114 are used to absorb microwaves generated by the microwave heating section 108.

[0095] In this embodiment, the serving part 106 includes a serving plate 110 for placing food ingredients. The serving plate 110 has multiple serving areas 112 on one side, and each serving area 112 can hold food ingredients. This allows different food ingredients to be placed in different serving areas 112 when cooking different food ingredients, preventing the food ingredients from moving and mixing during cooking, and ensuring the cooking effect of each food ingredient when cooking different food ingredients.

[0096] Furthermore, the holding section 106 also includes multiple microwave absorbing elements 114, and the number of microwave absorbing elements 114 is the same as the number of holding areas 112. Each microwave absorbing element 114 is arranged in a one-to-one correspondence with a holding area 112, and each microwave absorbing element 114 is attached to the holding tray 110 and located on the back side of the corresponding holding area 112. The microwave absorbing elements 114 are used to absorb microwaves generated by the microwave heating unit 108, and while absorbing microwaves, the microwave absorbing elements 114 can also heat up, thereby heating the corresponding holding area 112 through the microwave absorbing elements 114, and frying the food held in the holding area 112 during the heating process.

[0097] Specifically, the microwave absorbing element 114 can be made of microwave absorbing material.

[0098] It is understandable that during the operation of the microwave heating section 108, the closer the microwave outlet is to the microwave absorbing element 114, the more microwaves the microwave absorbing element 114 absorbs. Therefore, the microwave absorbing element 114 heats up faster than the microwave absorbing element 114 which is farther away from the microwave outlet, and thus the heating rate of the holding area 112 is faster.

[0099] Furthermore, the holding part 106 also includes a shielding member 116, which is disposed between two adjacent absorbing members 114 and is used to shield microwave conduction between two adjacent absorbing members 114.

[0100] Specifically, the holding section 106 also includes a shielding member 116, which is disposed between two adjacent absorbing members 114. By disposing of the shielding member 116, the microwaves between the two adjacent absorbing members 114 can be shielded, avoiding interference between the microwaves of the two adjacent holding areas 112, thereby ensuring the temperature change effect of the two adjacent holding areas 112 and thus ensuring the effect of zoned heating.

[0101] Specifically, the shielding component 116 can be made of graphene material to ensure the shielding effect of the microwave absorbing component 114 on microwaves.

[0102] In any of the above embodiments, further, as Figure 2 As shown, the microwave heating unit 108 includes a magnetron, which generates microwaves when connected to a power source. This allows the microwave heating unit 108 to generate microwaves to heat the food inside the cooking cavity 104, and for the microwave absorber 114 of the serving section 106 to absorb the microwaves, enabling the serving section 106 to fry the food. Specifically, the magnetron is disposed inside the housing 102 of the cooking appliance 100 and located outside the cooking cavity 104.

[0103] Furthermore, the microwave heating unit 108 also includes a waveguide. By providing the waveguide, the direction of microwave conduction generated by the magnetron can be guided during the operation of the microwave heating unit 108. That is, by setting the extension direction of the waveguide, the microwave is guided to the corresponding position. Specifically, the inlet of the waveguide can be configured to be connected to the magnetron. When the magnetron generates microwaves, the microwaves can enter the waveguide through the inlet and then be led out to the corresponding position from the outlet of the waveguide. Furthermore, the outlet of the waveguide can be moved relative to the holding unit 106, so that the microwaves emitted by the microwave holding unit 106 can be emitted towards different positions of the holding unit 106 under the guidance of the waveguide. This results in different amounts of microwaves received at different positions of the holding unit 106, and consequently, different heating rates at different positions of the holding unit 106.

[0104] In any of the above embodiments, further, as Figure 2 As shown, the cooking appliance 100 also includes an image acquisition unit 118, which is disposed in the cooking cavity 104 and is used to acquire image information of the holding part 106 and the food ingredients in the cooking cavity 104; the cooking appliance 100 also includes a controller, which is connected to the image acquisition unit 118 and the microwave heating unit 108 respectively, and is used to control the heating position of the microwave heating unit 108 according to the image information.

[0105] In this embodiment, the cooking appliance 100 further includes an image acquisition unit 118 and a controller. The image acquisition unit 118 is used to acquire image information inside the cooking cavity 104. The image acquisition unit 118 is connected to the controller, so the image acquisition unit 118 can transmit the acquired image inside the cooking cavity 104 to the controller. The controller is also connected to the microwave heating unit 108, so that the controller can control the operation of the microwave heating unit 108 according to the image information inside the cooking cavity 104 acquired by the image acquisition unit 118. This further improves the automation level of the cooking appliance 100, facilitates user operation, and enhances the user experience.

[0106] Specifically, by acquiring the image information inside the cooking cavity 104 through the image acquisition unit 118, the controller can determine whether there is a holding part 106 inside the cooking cavity 104. If there is no holding part 106 inside the cooking cavity 104, it can be determined that the current cooking appliance 100 will operate in normal mode, that is, the food will be heated directly by the microwave generated by the microwave heating unit 108. At this time, the outlet of the microwave heating unit 108 can be kept in the initial position. The controller controls the microwave heating unit 108 to operate so as to realize the direct heating of the food by microwave.

[0107] If a holding section 106 is placed inside the cooking cavity 104, it can be determined that the current cooking appliance 100 will fry the food through the holding section 106, which is the frying mode of the cooking appliance 100. At this time, the controller also needs to determine the type and weight of the food in different holding areas 112 on the holding section 106 through image information, and then determine the heating temperature required for each holding area 112. Finally, the controller can control the outlet position of the waveguide of the microwave heating unit 108 according to the different heating temperatures required for different holding areas 112. After adjusting the outlet position of the waveguide, the controller can control the operation of the microwave heating unit 108 to achieve regional cooking of different foods.

[0108] In addition, in the frying mode of the cooking appliance 100, the user can also manually input different heating temperatures required for different serving areas 112. After receiving the heating temperature input by the user, the controller controls the outlet position of the waveguide according to the heating temperature, and then controls the microwave heating unit 108 to operate for zoned cooking.

[0109] According to the second aspect of this application, such as Figure 5 As shown, a control method for a cooking appliance is proposed. This control method can be used for any of the cooking appliances described in the above-mentioned technical solutions. The control method includes:

[0110] S502, Obtain the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section;

[0111] S504, determine the position of the first target based on the heating temperature of the first target and the heating temperature of the second target;

[0112] S506, control the microwave heating element to move to the first target position;

[0113] S508 controls the operation of the microwave heating unit based on the microwave heating unit being located at the first target position.

[0114] The control method for cooking appliances provided by the present invention can be used in any of the cooking appliances described in the above technical solutions. The cooking appliance includes a cooking cavity and a holding part. The holding part includes different holding areas for placing food ingredients. The cooking appliance also includes a microwave heating part. The microwave outlet of the microwave heating part can move relative to the holding part to emit microwaves toward different positions of the holding part, so that different areas of the holding part have different heating rates.

[0115] Specifically, during the operation of the cooking appliance, firstly, the second target heating temperature and the first target heating temperature of two adjacent serving areas on the serving section are obtained. It can be understood that at this time, the user needs to fry different ingredients using the frying function of the cooking appliance. The user can put two different ingredients into the two adjacent serving areas respectively, and then set different target heating temperatures for the two serving areas according to the different ingredients, namely the second target heating temperature and the first target heating temperature.

[0116] Then, the first target position of the microwave outlet of the microwave heating unit is determined according to the second target heating temperature and the first target heating temperature. Specifically, when the first target heating temperature is greater than the second target heating temperature, the first target position is located near the holding area corresponding to the first target heating temperature, so that the heating rate of the holding area is greater than that of the other holding area, thereby meeting the cooking requirements of the food held in the holding area, and also meeting the cooking cavity requirements of the food in the other holding area.

[0117] Furthermore, by controlling the microwave outlet of the microwave heating unit to move to the first target position, and then controlling the operation of the microwave heating unit, it is possible to achieve zoned heating of two different ingredients.

[0118] The control method for cooking appliances provided by this invention obtains different heating temperatures for different serving areas, namely a second target heating temperature and a first target heating temperature. Based on these temperatures, a first target position of the microwave outlet of the microwave heating unit is determined. The microwave heating unit is then moved so that the microwave outlet is positioned at the first target position. This allows the microwave outlet to be moved to the appropriate position according to the cooking requirements of different ingredients, ensuring that the heating rate of different areas of the serving area matches the cooking requirements of the ingredients. Furthermore, this method achieves simultaneous heating of different ingredients in different areas while maintaining optimal cooking results. In other words, it enables zoned heating of the cooking appliance, further expanding its functionality beyond its frying function and improving the user experience.

[0119] According to one embodiment of the present invention, such as Figure 6 As shown, a method for controlling a cooking appliance is proposed, including:

[0120] S602, Obtain the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section;

[0121] S604, determine the position of the first target based on the heating temperature of the first target and the heating temperature of the second target;

[0122] S606, control the microwave heating element to move to the first target position;

[0123] S608 controls the operation of the microwave heating unit based on the microwave heating unit being located at the first target position;

[0124] S610, respectively obtain the first target heating time and the second target heating time of two adjacent holding areas;

[0125] S612, based on the first target heating time of the microwave heating unit, control the microwave heating unit to move from the first target position to the second target position;

[0126] S614 controls the microwave heating unit to stop operating based on the second target heating time of the microwave heating unit.

[0127] Wherein, the heating time of the first target is less than the heating time of the second target, and when the microwave heating part is in the position of the second target, the microwave outlet is opposite to the holding area corresponding to the heating time of the second target.

[0128] In this embodiment, the first target heating time and the second heating time of two adjacent serving areas can also be obtained, which are different heating times required for different ingredients. Thus, in addition to achieving different heating temperatures for different ingredients, different ingredients on the serving section can be heated according to different heating times, further ensuring the cooking effect of different ingredients and improving the user experience.

[0129] Specifically, the first target heating time is shorter than the second target heating time. After the microwave outlet of the microwave heating unit moves to the first target position, the microwave heating unit is controlled to operate, thereby heating the two adjacent serving areas. Simultaneously, a timer starts. When the microwave heating unit continues operating until the first target heating time has elapsed, it indicates that the food corresponding to the first target heating time has been cooked. At this point, the microwave heating unit can be controlled to move from the first target position to the second target position. When the microwave heating unit is in the second target position, the microwave outlet is opposite the serving area corresponding to the second target heating time. Specifically, at this point, the distance between the microwave outlet and the serving area is the shortest, and the distance to the adjacent serving area is the longest. In other words, when the food corresponding to the first target heating time has been cooked, there is no need to heat that serving area further. Therefore, there is no need to keep the microwave outlet in the first target position; instead, the microwave outlet is moved to the second target position to cook the remaining food separately, thus avoiding energy waste, improving heating efficiency, and enhancing the user experience.

[0130] It is understandable that when the microwave heating unit is moved to the second target position, in order to ensure that the temperature of the corresponding serving area is maintained at the temperature required by the food, the operating power of the microwave heating unit can be adjusted appropriately to ensure the cooking effect of the food.

[0131] According to one embodiment of the present invention, such as Figure 7 As shown, a method for controlling a cooking appliance is proposed, including:

[0132] S702, obtain the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section;

[0133] S704, based on the first target heating temperature and the second target heating temperature, determine the target holding area that the microwave outlet faces when the microwave heating unit is located at the first target position;

[0134] S706, when the microwave heating part is located at the first target position according to the preset formula, the distance between the microwave outlet and the center line of the connection between two adjacent holding areas is determined.

[0135] S708, determine the location of the first target based on the target holding area and the distance between the microwave outlet and the centerline;

[0136] S710 controls the microwave heating element to move to the first target position;

[0137] S712 controls the operation of the microwave heating unit based on the microwave heating unit being located at the first target position.

[0138] In this embodiment, the first target position of the microwave heating unit can be determined based on the second target heating temperature and the first target heating temperature, and in the following manner. First, the holding area facing the microwave outlet is determined based on the second target heating temperature and the first target heating temperature. Specifically, when the first target heating temperature is greater than the second target heating temperature, it can be determined that when the microwave heating unit is in the first target position, the microwave outlet faces the holding area corresponding to the first target heating temperature. Conversely, when the first target heating temperature is less than the second target heating temperature, it can be determined that when the microwave heating unit is in the first target position, the microwave outlet faces the holding area corresponding to the second target heating temperature. In other words, when the microwave heating unit is in the first target position, the microwave outlet faces the holding area corresponding to the higher target heating temperature, thereby making the heating rate of the holding area faster to ensure that the target temperature can be reached quickly.

[0139] Furthermore, after determining the holding area facing the microwave outlet, the distance between the microwave outlet and the center line of the connection between the two adjacent holding areas can be calculated using a preset formula based on the specific values ​​of the second target heating temperature and the first target heating temperature. After determining the orientation of the microwave outlet and the distance between the microwave outlet and the center line, the first target position can be determined.

[0140] Specifically, the preset formula is: Where L is the distance between the microwave outlet and the centerline, T is a constant that can be set according to the rated power of the cooking appliance or other fixed parameters of the cooking appliance. T1 is the higher of the second target heating temperature and the first target heating temperature, T2 is the lower of the second target heating temperature and the first target heating temperature, and S is the maximum distance between the microwave heating outlet and the centerline when the microwave heating outlet is opposite the serving area corresponding to the higher of the second target heating temperature and the first target heating temperature.

[0141] For example, a user needs to cook two steaks of different weights, one 150g and the other 350g. After preheating the cooking cavity, the two steaks are placed in two adjacent serving areas. The user sets the cooking temperature for the 150g steak to 200 degrees Celsius and the cooking temperature for the 350g steak to 230 degrees Celsius. At this point, the first target position of the microwave heating unit is determined, with the microwave outlet facing the serving area containing the 350g steak. The distance between the microwave outlet and the center line between the two serving areas is calculated according to a preset formula. Specifically, the constant T is 150, and the maximum distance between the microwave outlet and the center line in the serving area containing the 350g steak is 15 centimeters. These values ​​are then substituted into the preset formula. That is, the distance between the microwave outlet and the center line is 3 centimeters.

[0142] According to one embodiment of the present invention, such as Figure 8 As shown, a method for controlling a cooking appliance is proposed, including:

[0143] S802 receives a preheating command input by the user and determines the first preheating temperature and the second preheating temperature of two adjacent holding areas on the holding section according to the preheating command.

[0144] S804, determine the third target position based on the first preheating temperature and the second preheating temperature;

[0145] S806, controls the microwave heating element to move to the third target position;

[0146] S808 controls the operation of the microwave heating unit based on the fact that the microwave heating unit is located at the third target position;

[0147] S810, obtain the first and second actual temperatures of two adjacent holding areas;

[0148] S812, based on the first actual temperature reaching the first preheating temperature, control the microwave heating unit to move from the third target position to the fourth target position;

[0149] S814, based on the second actual temperature reaching the second preheating temperature, the controlled microwave heating unit stops operating;

[0150] S816, obtain the first target heating temperature and the second target heating temperature of two adjacent holding areas on the holding section;

[0151] S818, determine the position of the first target based on the heating temperature of the first target and the heating temperature of the second target;

[0152] S820 controls the microwave heating element to move to the first target position;

[0153] S822 controls the operation of the microwave heating unit based on the microwave heating unit being located at the first target position.

[0154] In this embodiment, before frying the food on the serving section, the cooking cavity can be preheated according to the cooking requirements of the food. That is, before obtaining the second target heating temperature and the first target heating temperature of two adjacent serving areas on the serving section, the two adjacent serving areas of the serving section are preheated.

[0155] Specifically, the system receives a preheating command input by the user. This command can include different preheating temperatures for two serving areas. It's understood that the user needs to fry different ingredients using the cooking appliance's frying function; therefore, the serving areas for the two different ingredients also require different preheating temperatures—a first preheating temperature and a second preheating temperature. Then, based on the first and second preheating temperatures, a third target position for the microwave outlet of the microwave heating unit is determined. Specifically, when the first preheating temperature is higher than the second preheating temperature, the third target position is located closer to the serving area corresponding to the first preheating temperature. This ensures that the heating rate of this serving area is greater than that of the other serving area, thus meeting the cooking requirements of the ingredients in this area while also satisfying the second preheating temperature requirement of the other serving area. Further, the microwave outlet of the microwave heating unit is moved to the third target position, and then the microwave heating unit is controlled to operate, thus achieving preheating of both serving areas.

[0156] Furthermore, during the preheating process of the cooking cavity, once the microwave heating unit moves to the third target position and starts operating, it can acquire the first and second actual temperatures of the two adjacent serving areas in real time. Then, it can control the microwave heating unit based on the first and second actual temperatures. In other words, when the two serving areas reach the corresponding first and second actual temperatures, heating of the serving area can be stopped, which can save energy and improve the efficiency of preheating.

[0157] Specifically, the first preheating temperature is lower than the second preheating temperature, and the first actual temperature is lower than the second actual temperature. During the operation of the microwave heating unit, when the first actual temperature of the holding area corresponding to the first preheating temperature reaches the first preheating temperature, the preheating of the holding area is completed. At this time, the microwave heating unit can be controlled to move from the third target position to the fourth target position. When the microwave heating unit is in the fourth target position, the microwave outlet is opposite to the holding area corresponding to the second preheating temperature. Specifically, at this time, the distance between the microwave outlet and the holding area is the shortest, and the distance to the adjacent holding area is the longest. That is to say, when the holding area corresponding to the first preheating temperature has been preheated, there is no need to heat the holding area. Therefore, there is no need to keep the microwave outlet in the third target position. Instead, the microwave outlet is moved to the fourth target position to heat the holding area that has not been preheated, thereby avoiding energy waste, improving preheating efficiency, and improving user experience.

[0158] Furthermore, the third target position of the microwave heating unit can be determined based on the first preheating temperature and the second preheating temperature, and in the following manner. First, the holding area facing the microwave outlet is determined based on the first preheating temperature and the second preheating temperature. Specifically, when the first preheating temperature is greater than the second preheating temperature, it can be determined that when the microwave heating unit is in the third target position, the microwave outlet faces the holding area corresponding to the first preheating temperature. Conversely, when the first preheating temperature is less than the second preheating temperature, it can be determined that when the microwave heating unit is in the third target position, the microwave outlet faces the holding area corresponding to the second preheating temperature. In other words, when the microwave heating unit is in the third target position, the microwave outlet faces the holding area corresponding to the higher preheating temperature, thereby making the heating rate of that holding area faster to ensure that the target temperature can be reached quickly.

[0159] Furthermore, after determining the holding area facing the microwave outlet, the specific values ​​of the first and second preheating temperatures can be used, through the aforementioned preset formula: When the microwave heating unit is in the third target heating position, the distance between the microwave outlet and the center line of the connection between the two adjacent holding areas is calculated. After determining the orientation of the microwave outlet and the distance between the microwave outlet and the center line, the third target position can be determined.

[0160] For example, a user needs to cook two different types of ingredients: a steak weighing 300g and a pork chop, both weighing 300g. Before cooking, the user sets the preheating temperature of the steak's serving area to 230 degrees Celsius and the pork chop's serving area to 180 degrees Celsius. That is, the first and second preheating temperatures are 180 degrees Celsius and 230 degrees Celsius, respectively. Then, a third target position is determined using a preset formula. Specifically, the constant T is 150, and the maximum distance between the microwave outlet and the center line in the steak's serving area is 15 centimeters. These values ​​are then substituted into the preset formula. That is, the distance between the microwave outlet and the center line is 5 centimeters.

[0161] Furthermore, when the temperature of the serving area where the steak is located reaches 230 degrees Celsius, the microwave heating unit is controlled to move to the opposite side of the serving area where the pork chop is located, that is, to heat the serving area where the pork chop is located separately until the area reaches 180 degrees Celsius, which indicates that the preheating is complete.

[0162] After the cooking chamber is preheated, place the steak and pork chop into two adjacent serving areas. Set the heating temperature for both steak and pork chop to 230 degrees Celsius. The steak needs to be heated for 1 minute and 50 seconds, and the pork chop for 5 minutes. At this point, align the microwave outlet of the microwave heating unit with the center line of the two adjacent serving areas to ensure that both areas are heated evenly. When the microwave heating unit has been running for 1 minute and 50 seconds, it indicates that the steak is cooked. At this point, move the microwave heating unit so that the microwave outlet is aligned with the serving area of ​​the pork chop, that is, heat the pork chop separately. At this point, the power of the microwave heating unit can be adjusted to ensure that the temperature of the serving area of ​​the pork chop is maintained at 230 degrees Celsius. When the microwave heating unit has been running for 5 minutes, it indicates that the pork chop is also cooked.

[0163] According to one embodiment of the present invention, such as Figure 9 As shown, a method for controlling a cooking appliance is proposed, including:

[0164] S902, Obtain the image of the food on the serving section;

[0165] S904, based on the food image, determine the first target heating temperature and the second target heating temperature of two adjacent serving areas on the serving section;

[0166] S906, determine the position of the first target based on the heating temperature of the first target and the heating temperature of the second target;

[0167] S908, controls the microwave heating element to move to the first target position;

[0168] S910 controls the operation of the microwave heating unit based on the microwave heating unit being located at the first target position.

[0169] In this embodiment, an image acquisition unit can be used to acquire images of the food inside the cooking cavity. These images are then used to determine the type and weight of the food in different serving areas on the serving unit, and subsequently, the required second and first target heating temperatures for two adjacent serving areas are determined. By acquiring food images and determining the second and first target heating temperatures for the two serving areas based on these images, the user is no longer required to manually input the second and first target heating temperatures, further enhancing the intelligence of the cooking appliance and improving the user experience.

[0170] According to a third aspect of this application, a control device for a cooking appliance is proposed. An acquisition unit acquires different heating temperatures for different serving areas, namely a second target heating temperature and a first target heating temperature. This allows a determining unit to determine a first target position of the microwave outlet of the microwave heating unit based on the second and first target heating temperatures. Then, a controller moves the microwave heating unit so that the microwave outlet is positioned at the first target position. This achieves the goal of moving the microwave outlet of the microwave heating unit to the appropriate position according to the cooking requirements of different ingredients, ensuring that the heating rate of different areas of the serving area matches the cooking requirements of the ingredients. Furthermore, by simultaneously heating different ingredients in different areas, the device guarantees the cooking effect of different ingredients, thus achieving zoned heating of the cooking appliance. This further expands the functionality of the cooking appliance beyond its frying function, improving the user experience.
