Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0021] With the development of science and technology, cooking appliances are becoming more and more intelligent, and the cooking cavities of cooking appliances are becoming more and more diverse. Exemplarily, an air fryer may include a square frying barrel, or, for another example, an air fryer may include a cylindrical frying barrel, etc. In the related art, most cooking appliances use heating tubes for cooking food. However, since the heating area of the heating tube is small and the power deviation of the intermittent heating control is large, the cooking of food by the cooking appliance is prone to problems such as uneven heating and poor performance of the food cooked based on the menu of the cooking appliance. Therefore, in the related art, there is a problem of low cooking performance during the process of cooking food by the cooking appliance.

[0022] In view of the above problems, through long-term research, the inventor has found and proposed a cooking appliance, a cooking method, and a device provided by an embodiment of the present application. By controlling the cooperation of a heating element including an electromagnetic heating element and other heating elements in the heating device except the heating element including the electromagnetic heating element during the cooking mode of the cooking appliance, the temperature uniformity in the cooking cavity is improved, thereby improving the cooking performance of the cooking appliance. Among them, the specific cooking method will be described in detail in the subsequent embodiments.

[0023] Please refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural diagram of a cooking appliance provided by an embodiment of the present application. Figure 2 which shows a schematic diagram of a cooking appliance provided by an embodiment of the present application. In the embodiment of the present application, the cooking appliance 10 may include a housing assembly 11, a frying barrel 12, a heating device 13, and a control assembly 14.

[0024] Among them, the housing assembly 11 is provided with a receiving cavity, and the frying barrel 12 is movably disposed in the receiving cavity. Among them, the frying barrel 12 may include a bottom wall and a peripheral wall. Among them, the heating device 13 includes a first heating element 131 and a second heating element 132. The first heating element 131 is disposed in the housing assembly 11 and above the cooking cavity, and the second heating element 132 is disposed in the housing assembly 11 and below the bottom wall. Among them, at least one of the first heating element 131 and the second heating element 132 includes an IH electromagnetic heating element. Among them, the control assembly 14 is connected to the heating device 13 and is configured to obtain the cooking duration and the cooking temperature during the cooking mode of the cooking appliance 10, and control the heating parameters of the heating element including the electromagnetic heating element and the heating parameters of other heating elements in the heating device 13 except the heating element including the electromagnetic heating element, such as the heating time, the heating power, etc.

[0025] Among them, the cooking appliance 10 may have functions such as cooking and keeping warm. Among them, the cooking appliance 10 can generate hot air through the heating device 13, and then make the hot air circulate rapidly in a sealed space through a hot air convection system, thereby realizing the method of heating food. In the embodiment of the present application, the cooking appliance 10 may be an air fryer with a cooking function.

[0026] Among them, according to Figure 2It can be seen that the outer shell assembly 11 plays a supporting role. The outer shell assembly 11 includes a bottom cover, side walls, and a top plate. The bottom cover and the top plate are spaced apart in a specified direction. The specified direction refers to the direction perpendicular to the plane where the bottom cover is located. One side of the side wall is circumferentially connected to the periphery of the bottom cover, and the other side is circumferentially connected to the periphery of the top plate. The outer shell assembly 11 is provided with a receiving cavity for receiving the frying barrel 12. An opening is formed in the side wall for placing the frying barrel 12 in the receiving cavity.

The control panel includes one or more function controls, and the above function controls include but are not limited to a start control, a reservation control, a time setting control, a mode setting control, a food type setting control, etc.

[0028] The frying barrel 12 can be movably arranged in the receiving cavity.

The frying barrel 12 includes a bottom wall and a peripheral wall, and the peripheral wall is circumferentially connected to the periphery of the bottom wall to jointly form a cooking cavity for receiving food.

[0029] The heating device 13 is used to implement the cooking function of the cooking appliance 10. Among them, the heating device 13 can include a first heating element 131 and a second heating element 132. The first heating element 131 is arranged in the outer shell assembly 11 and is located above the cooking cavity, and the second heating element 132 is arranged in the outer shell assembly 11 and is located below the bottom wall. Among them, at least one of the first heating element 131 and the second heating element 132 includes an IH electromagnetic heating element.

[0030] Optionally, the first heating element 131 can include a heating tube, an infrared heating plate, a heating belt, an IH electromagnetic heating element, etc.; the second heating element 132 can include a heating tube, an infrared heating plate, an IH electromagnetic heating element, etc., which are not limited herein. Among them, the first heating element 131 and the second heating element 132 can be the same heating device or different heating devices; among them, the maximum power of the first heating element 131 and the second heating element 132 can be the same or different.

[0031] Exemplarily, the maximum power of the first heating element 131 is greater than the maximum power of the second heating element 132. For example, the first heating element 131 can include an IH coil with operating parameters of DC voltage 220V, 50Hz, and 1500W. It can be understood as the upper IH heating system; the second heating element 132 can include a heating tube with parameters of DC voltage 220V, 50Hz, and 500W.

[0032] In some embodiments, the first heating element 131 may be disposed corresponding to the cooking cavity and fixedly arranged in the housing assembly 11 through a fixing structure, and is used to generate heat when the cooking appliance 10 is in the cooking mode, so as to raise the temperature of the gas in the cooking cavity. The second heating element 132 may be disposed in the housing assembly 11 corresponding to the bottom wall of the frying barrel 12, and is used to generate heat when the cooking appliance 10 is in the cooking mode, so as to raise the temperature of the gas in the cooking cavity. It should be noted that the fixing structure for fixing the first heating element 131 and the fixing structure for fixing the second heating element 132 may be the same or different.

[0033] In this embodiment, the control assembly 14 may be respectively connected to the first heating element 131 and the second heating element 131, and is used to control the heating parameters of the first heating element 131 and the second heating element 132 during the process when the cooking appliance 10 is in the cooking mode.

[0034] In some embodiments, the heating power of the first heating element 131 may remain unchanged or may change, and the heating power of the second heating element 132 may remain unchanged or may change. Further, in this embodiment, the control assembly 14 may control the heating time and / or heating power of the first heating element 131 and the heating time and / or heating power of the second heating element 132 during the process when the cooking appliance 10 is in the cooking mode, so that the first heating element 131 and the second heating element 132 cooperate to generate heat, ensuring the temperature uniformity in the cooking cavity, and further improving the cooking performance of the cooking appliance 10.

[0035] In some embodiments, the control assembly 14 is further connected to the control panel on the housing assembly 11. When the control panel receives an operation signal for any one of the function controls, it generates a corresponding electrical signal and sends it to the control assembly 14. The control assembly 14 may control the cooking appliance 10 based on this electrical signal. Optionally, the control assembly 14 may include a Micro Controller Unit (MCU).

[0036] Please refer to again Figure 2 , in some embodiments, considering that the IH heating system generates heat faster and has a larger heat generation area than the heating tube, in this embodiment, the heating element including the IH electromagnetic heating element may further include a hot air blower 133. The hot air blower 133 is disposed in the housing assembly 11 and is on the side closer to the cooking cavity relative to the electromagnetic heating element, and is used to blow the heat generated by the electromagnetic heating element towards the cooking cavity, thereby accelerating the heat flow in the cooking cavity, improving the rate of heat conduction, improving the cooking efficiency of the cooking appliance 10, and also improving the temperature uniformity in the cooking cavity when the cooking appliance 10 cooks food.

[0037] Among them, the hot air blower 133 can be integrated with the heating element including the IH electromagnetic heating element, and is fixedly arranged in the housing assembly 11 through a fixing structure. In some embodiments, the hot air blower 133 can also be used to cause the hot gas generated by the heating of the first heating element 131 to circulate convectively in the cooking cavity, thereby heating the food. It should be noted that the fixing structure for fixing the first heating element 131 and the fixing structure for fixing the hot air blower 133 can be the same or different.

[0038] Among them, the hot air blower 133 can be driven by a motor to rotate the fan blade for blowing, and can include multiple gears, such as high gear (rotation speed above 2500 rpm / min), medium gear (rotation speed of 1500 - 2500 rpm / min), low gear (rotation speed below 1500 rpm / min), etc. Exemplarily, the hot air blower 133 can include a fan with parameters of DC220V, 50Hz, and 1000W.

[0039] Among them, when the cooking appliance 10 includes the hot air blower 133, the control component 14 is connected to the hot air blower 133 and is used to control the working parameters of the hot air blower 133, such as controlling the rotation speed, rotation duration, etc. of the hot air blower 133.

[0040] In some embodiments, considering that the hot air blower 133 is located on the side closer to the cooking cavity relative to the IH electromagnetic heating element, the hot air blower 133 can accelerate the heat dissipation of the heating element including the electromagnetic heating element. Considering that the electromagnetic heating element can be integrated with the hot air blower 133, in this embodiment, the maximum power of the first heating element 131 can be set to be greater than the maximum power of the second heating element 132 to improve the cooking efficiency of the cooking appliance and the temperature uniformity in the cooking cavity.

[0041] Please refer to again Figure 2 , in some embodiments, the cooking appliance 10 can further include a first temperature detection device 15 and a second temperature detection device 16. Among them, the first temperature detection device 15 is arranged in the housing assembly 11 and above the cooking cavity, and is used to detect the temperature above the cooking cavity; the second temperature detection device 16 can be arranged below the bottom wall of the frying bucket 12 and is used to detect the temperature of the bottom wall.

[0042] Among them, the first temperature detection device 15 may include a thermocouple detection circuit, a thermistor NTC detection circuit, etc., and the second temperature detection device 16 may include a thermocouple detection circuit, an NTC detection circuit, etc.; among them, the first temperature detection device 15 may be the same as or different from the second temperature detection device 16, which is not limited herein. Optionally, the thermocouple detection circuit may be composed of multiple circuit elements. For example, the thermocouple detection circuit may be composed of one or more resistor elements, one or more capacitor elements, one or more comparator elements, etc.; the NTC detection circuit may be composed of multiple circuit elements. For example, the NTC detection circuit is composed of one or more resistor elements, one or more capacitor elements, one or more comparator elements, etc.

[0043] Exemplarily, the first temperature detection device 15 may include an NTC detection circuit, and the second temperature detection device 16 may include an NTC detection circuit to detect the temperature above the cooking cavity based on the NTC detection circuit and detect the temperature of the bottom wall of the frying barrel 12 based on the NTC detection circuit.

[0044] When the cooking appliance 10 includes the first temperature detection device 15 and the second temperature detection device 16, the first temperature detection device 15 may be connected to the control component 14 for reporting the detected temperature above the cooking cavity to the control component 14, and the second detection device 103 may be connected to the control component 14 for reporting the detected temperature of the bottom wall to the control component 14.

[0045] Among them, the control component 14 may adjust the heating parameters of the first heating element 131 and the second heating element 132 based on the obtained temperature above the cooking cavity and the temperature of the bottom wall, so as to achieve precise control of the temperature in the cooking cavity and improve the uniformity of the temperature in the cooking cavity.

[0046] In some embodiments, the cooking appliance 10 may further include a water level sensor. Among them, the water level sensor may be disposed in the frying barrel 12 for detecting the water volume in the frying barrel 12. Among them, the water level sensor may include sensors of types such as a capacitive liquid level sensor, a float type liquid level sensor, and a radar liquid level sensor.

[0047] Wherein, when the cooking appliance 10 includes a water level sensor, the water level sensor can be connected to the control component 14 and used to report the detected water volume in the frying bucket 12 to the control component 14. Correspondingly, the control component 14 can determine the optimal working mode of the cooking appliance 10 based on this water volume, such as, air frying mode, boiling mode, etc. Exemplarily, if the control component 14 detects that the water volume in the frying bucket 12 is greater than a preset water volume, it can determine that the optimal working mode of the cooking appliance 10 is the boiling mode, and then can control the cooking appliance 10 to enter the boiling mode, or output a confirmation pending message for the boiling mode to obtain a mode determination instruction input by the user based on this confirmation pending message. Exemplarily, if the control component 14 detects that the water volume in the frying bucket 12 is less than or equal to the preset water volume, it can determine that the optimal working mode of the cooking appliance 10 is the air frying mode.

[0048] In some embodiments, the control component 14 can execute the current cooking process after receiving a cooking instruction. During the current cooking process, the control component 14 can determine the cooking temperature and cooking duration when the cooking appliance 10 is in the cooking mode, and control the heating parameters of the heating elements including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device 13 except the heating elements including the electromagnetic heating element based on this cooking duration and this cooking temperature. Thus, by controlling the cooperation of the heating elements including the electromagnetic heating element and the other heating elements in the heating device 13 when the cooking appliance 10 is in the cooking mode, the uniformity of the temperature in the cooking cavity is improved, thereby improving the cooking performance of the cooking appliance 10.

[0049] Please refer to Figure 3 , Figure 3 FIG. shows a schematic flowchart of a cooking method provided by an embodiment of the present application. This cooking method improves the uniformity of the temperature in the cooking cavity by controlling the cooperation of the heating elements including the electromagnetic heating element and the other heating elements in the heating device when the cooking appliance is in the cooking mode, thereby improving the cooking performance of the cooking appliance. In a specific embodiment, this cooking method can be applied to a cooking device 200 as shown in Figure 6 and a cooking appliance 10 configured with the cooking device 200 ( Figure 7 ). Hereinafter, taking the cooking appliance as an example, the specific process of this embodiment will be described. Of course, it can be understood that the cooking appliance to which this embodiment is applied can include an air fryer, an oven, a microwave oven, etc., which are not limited herein. Hereinafter, the process shown in Figure 3 will be elaborated in detail. The cooking method can specifically include the following steps:

[0050] Step S110: Obtain the cooking duration and the cooking temperature when the cooking appliance is in the cooking mode.

[0051] In some embodiments, the cooking appliance may include operating modes such as a cleaning mode, a cooking mode, a warming mode, a standby mode, etc. Among them, in the cooking mode, the cooking appliance can perform air frying cooking, pressure cooking, boiling cooking, etc. on the food placed in the cooking appliance. Among them, in the standby mode, each component included in the cooking appliance can be in a standby state, and the cooking appliance can also receive a control instruction input by the user and switch the operating mode of the cooking appliance based on the control instruction. Exemplarily, the cooking appliance can receive a first cooking instruction input by the user in the standby mode and cook the food placed in the cooking appliance in response to the first cooking instruction.

[0052] As an implementable manner, the cooking appliance can receive a first cooking instruction input by the user, wherein the first cooking instruction may carry a cooking duration and a cooking temperature. Correspondingly, when receiving the first cooking instruction, the cooking appliance can determine that it is necessary to control the cooking appliance to enter the cooking mode. Further, the cooking appliance can parse the first cooking instruction to obtain the cooking duration and the cooking temperature carried by the first cooking instruction, and control the heating parameters of the heating device included in the cooking appliance based on the cooking duration and the cooking temperature to cook the food.

[0053] As another implementable manner, the cooking temperature corresponding to the cooking appliance remains constant. The cooking appliance can receive a second cooking instruction input by the user, wherein the second warming instruction does not carry a cooking temperature but carries a cooking duration. Correspondingly, when receiving the second cooking instruction, the cooking appliance can determine that it is necessary to control the cooking appliance to enter the cooking mode and parse the second cooking instruction to determine the cooking duration. Further, the cooking appliance can obtain the stored constant cooking temperature and control the heating parameters of the heating device included in the cooking appliance based on the cooking duration and the constant cooking temperature to cook the food.

[0054] In some embodiments, when the cooking appliance is in the cooking mode, the cooking appliance can obtain the cooking temperature and the cooking duration. Optionally, the cooking duration can be set independently by the user or obtained through third-party experimental data, such as 1 minute, 20 minutes, 50 minutes, etc.; the cooking temperature can be set independently by the user or obtained through third-party experimental data, such as 120 °C, 180 °C, 200 °C, etc., which is not limited herein.

[0055] Exemplarily, the cooking appliance is an air fryer, which includes functions such as a cooking function and a warming function. The user can press the button corresponding to the air fryer cooking function, and can also set the cooking duration and cooking temperature, and then press the button corresponding to the cooking function again to start the cooking appliance and enter the cooking mode. The cooking appliance can also enter the cooking mode after timing a preset start duration after receiving the cooking duration and cooking temperature set by the user, and control the heating parameters of the heating device included in the cooking appliance based on the cooking duration and cooking temperature to cook food.

[0056] During the process that the cooking appliance is in the cooking mode, it can control the function indicator light corresponding to the cooking mode to light up, can also perform a countdown display on the cooking duration corresponding to the cooking mode, and can also detect the temperature in the cooking cavity in real time. Among them, the functions corresponding to the cooking appliance in the cooking mode can include an air frying function, a boiling function, a pressure cooker function, etc., which are not limited herein.

[0057] Step S120: Control the heating parameters of the heating element including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device except for the heating element including the electromagnetic heating element based on the cooking duration and the cooking temperature.

[0058] In some embodiments, after the cooking appliance obtains the cooking temperature and cooking duration, it can control the heating parameters of the heating element including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device except for the heating element including the electromagnetic heating element based on the cooking temperature and the cooking duration.

[0059] As an implementable way, the first heating element can include an IH electromagnetic heating element, which can be understood as an upper IH heating system. Further, the cooking appliance can control the heating system parameters of the IH, such as heating power, heating time, etc. Exemplarily, the cooking appliance can control the upper IH to heat at the maximum power, and the cooking appliance can also control the upper IH to heat at the target power. Among them, the target power can be less than the maximum power of the upper IH. For example, the target power is within the range of 20%-80% of the maximum power of the upper IH.

[0060] As another implementable way, the second heating element can include an IH electromagnetic heating element, such as an IH coil. Further, the cooking appliance can control the heating system parameters of the IH coil, such as heating power, heating time, etc. Exemplarily, the cooking appliance can control the IH coil to heat at the maximum power, and the cooking appliance can also control the IH coil to heat at the target power. Among them, the target power can be less than the maximum power of the IH coil. For example, the target power is within the range of 20%-80% of the maximum power of the IH coil.

[0061] As another implementable manner, the first heating element may include a heating tube. Further, the cooking appliance may control the heating parameters of the heating tube, such as heating power, heating time, etc. Exemplarily, the cooking appliance may control the heating tube to continuously heat at the maximum power, or the cooking appliance may control the heating tube to heat for a first duration at the maximum power at a first time interval.

[0062] As yet another implementable manner, the second heating element may include a heating tube. Further, the cooking appliance may control the heating parameters of the heating tube, such as heating power, heating time, etc. Exemplarily, the cooking appliance may control the heating tube to continuously heat at the maximum power, or the cooking appliance may control the heating tube to heat for a second duration at the maximum power at a second time interval.

[0063] Optionally, the first time interval and the second time interval may be equal or unequal, and the first duration and the second duration may be equal or unequal; wherein, the first time interval, the second time interval, the first duration, and the second duration may be set independently by the user, or may be obtained respectively through third-party experimental data. For example, the first time interval and the second time interval are set to be equal and more than 10 seconds, and the first duration and the second duration are set to be equal and more than 5 seconds, etc.

[0064] In some embodiments, the cooking appliance may control the hot air blower to rotate during the process of entering the cooking mode to perform hot air circulation and improve the rate of heat flow. Exemplarily, during the process of the cooking appliance entering the cooking mode, the cooking appliance may control the hot air blower to rotate at a low gear, a medium gear, or a high gear.

[0065] In some embodiments, during the process of the cooking appliance entering the cooking mode, the cooking appliance may control the indicator light included in the cooking appliance to turn on, or may display the time of entering the cooking mode on the screen included in the cooking appliance. Further, according to the cooking duration and the duration of the cooking appliance entering the cooking mode, the cooking appliance may display a cooking countdown on the screen included in the cooking appliance. Additionally, the cooking appliance may also obtain the average value of the temperature above the cooking cavity and the temperature of the bottom wall of the frying barrel in real time, and display the average value on the screen included in the cooking appliance to improve the user experience.

[0066] It can be understood that in this embodiment, at least one heating element in the heating device included in the cooking appliance includes an IH electromagnetic heating element. Among them, the IH electromagnetic heating element has a larger heating area and generates heat faster than heating elements such as heating tubes and heating belts. By controlling the heating parameters of the heating element including the electromagnetic heating element and the heating parameters of other heating elements in the heating device except the heating element including the electromagnetic heating element, the heating elements included in the heating device are controlled to cooperate in heating to ensure the balance of the temperature in the cooking cavity, improve the uniformity of the temperature in the cooking cavity, improve the cooking performance of the cooking appliance, and also improve the user experience.

[0067] In an embodiment of the present application, the cooking method obtains the cooking duration and the cooking temperature during the cooking appliance being in the cooking mode; controls the heating parameters of the heating elements including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device except for the heating elements including the electromagnetic heating element based on the cooking duration and the cooking temperature, and then controls the heating elements including the electromagnetic heating element and the other heating elements in the heating device except for the heating elements including the electromagnetic heating element to cooperate during the cooking appliance being in the cooking mode, improving the temperature uniformity in the cooking cavity, and thus improving the cooking performance of the cooking appliance.

[0068] Please refer to Figure 4 , Figure 4 which shows a schematic flowchart of the cooking method provided by an embodiment of the present application. This method is applied to the above cooking appliance, and the following will elaborate in detail on the Figure 4 shown process. The cooking method may specifically include the following steps:

[0069] Step S210: During the cooking appliance being in the cooking mode, obtain the cooking duration and the cooking temperature.

[0070] For the specific description of step S210, please refer to the specific description of step S110 above, and details will not be repeated here.

[0071] Step S220: During the cooking duration, control the first heating element or the second heating element to continuously heat based on the maximum power.

[0072] In some embodiments, after the cooking appliance determines the cooking duration and the cooking temperature, it can control the first heating element or the second heating element to continuously heat based on the maximum power during the cooking duration.

[0073] Among them, the process of the cooking appliance controlling the first heating element or the second heating element to continuously heat based on the maximum power can be understood as the first charging stage during the cooking process. Among them, the first heating element and the second heating element continuously heating based on the maximum power can be understood as the first heating element and the second heating element both heating at full power. It can be understood that during the first charging stage of the cooking process, the heating elements included in the heating device are controlled to heat at full power to quickly increase the temperature in the cooking cavity and improve the cooking efficiency of the food.

[0074] In some embodiments, during the process of the cooking appliance controlling a heating element or the second heating element to heat at full power, that is, during the first charging stage of the cooking process, it can control the hot air blower to rotate to accelerate the hot air circulation in the cooking cavity, so that the heat quickly flows to each position in the cooking cavity, improving the temperature uniformity during the cooking process of the cooking appliance.

[0075] Exemplarily, the first heating element includes an IH coil, and the second heating element includes a heating tube. During the process of entering the cooking mode, the cooking appliance can control the IH heating system corresponding to the IH coil to perform full-power heating, and can also control the heating tube to perform full-power heating. Optionally, the cooking appliance can also control the hot air blower to rotate at a medium or high speed so as to circulate hot air, enabling the heat generated by the heating device to quickly flow to various places in the cooking cavity, improving the rate of heat flow and the temperature uniformity in the cooking cavity.

[0076] Step S230: Obtain the temperature above the cooking cavity as the first temperature, or obtain the temperature of the bottom wall as the second temperature.

[0077] In this embodiment, during the process of the cooking appliance being in the cooking mode, it can obtain the temperature above the cooking cavity detected by the first temperature detection device as the first temperature in real time, or can obtain the temperature of the bottom wall of the frying bucket detected by the second temperature detection device as the second temperature in real time.

[0078] Exemplarily, the first temperature detection device includes an NTC1 detection circuit, and the second temperature detection device includes an NTC2 detection circuit. During the process of the cooking cavity being in the cooking mode, the cooking appliance can obtain the temperature above the cooking cavity detected by the NTC1 detection circuit as the first temperature, and obtain the temperature of the bottom wall detected by the NTC2 detection circuit as the second temperature.

[0079] Step S240: Control the heating parameters of the heating device according to the first magnitude relationship between the first temperature and the cooking temperature or the second magnitude relationship between the second temperature and the cooking temperature.

[0080] In some embodiments, after the cooking appliance obtains the first temperature, it can compare the first temperature with the cooking temperature to obtain the first magnitude relationship; after the cooking appliance obtains the second temperature, it can compare the second temperature with the cooking temperature to obtain the second magnitude relationship.

[0081] Exemplarily, after the cooking appliance obtains the first temperature, it can subtract the cooking temperature from the first temperature to obtain the first difference, and use this first difference as the first magnitude relationship; after the cooking appliance obtains the second temperature, it can subtract the cooking temperature from the second temperature to obtain the second difference, and use this second difference as the second magnitude relationship.

[0082] In some embodiments, after the cooking appliance obtains the first size relationship and the second size relationship, it may control the heating parameters of the heating device according to the first size relationship or the second size relationship. Among them, the cooking appliance may obtain a first offset temperature value between the first temperature and the cooking temperature based on the first size relationship, or may obtain a second offset temperature value between the second temperature and the cooking temperature based on the second size relationship. Further, the cooking appliance may control the heating parameters of the heating device according to the first offset temperature value and the second offset temperature value.

[0083] Among them, the first offset temperature value may be understood as the first difference obtained by subtracting the cooking temperature from the first temperature; the second offset temperature value may be understood as the second difference obtained by subtracting the cooking temperature from the second temperature. Among them, the first difference may also be understood as the deviation between the first temperature and the cooking temperature, that is, the deviation between the temperature above in the cooking cavity and the cooking temperature; among them, the second difference may also be understood as the deviation between the second temperature and the cooking temperature, that is, the deviation between the temperature of the bottom wall of the frying barrel and the cooking temperature.

[0084] It can be understood that the smaller the first deviation is, the closer the temperature in the cooking cavity is to the optimal temperature for cooking the food, and the better the cooking effect is; the smaller the second deviation is, the closer the temperature in the cooking cavity is to the optimal temperature for cooking the food, and the better the cooking effect is. Correspondingly, the cooking appliance controls the heating parameters of the heating device according to the first offset temperature value and the second offset temperature value, which may include that if the first offset temperature value is less than the first temperature deviation value, or the second offset temperature value is less than the second temperature deviation value, it may control the heating element including the electromagnetic heating element to continuously heat based on the target power, and control other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for a first preset duration at a first time interval, so as to ensure the balance of the temperature in the cooking cavity by means of intermittent heating.

[0085] In some embodiments, the process of the cooking appliance controlling the heating parameters of the heating device according to the first size relationship between the first temperature and the cooking temperature or the second size relationship between the second temperature and the cooking temperature may also include that if it is determined based on the first size relationship that the first temperature is greater than the first set temperature, or it is determined based on the second size relationship that the second temperature is greater than the second set temperature, it may control the heating element including the electromagnetic heating element to continuously heat based on the target power, and control other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for a first preset duration at a first time interval.

[0086] Among them, the first set temperature can be obtained according to the cooking temperature and the first temperature threshold, the second set temperature can be obtained according to the cooking temperature and the second temperature threshold, and the second temperature threshold can be greater than the first temperature threshold. Optionally, the first set temperature can include the difference obtained by subtracting the first temperature threshold from the cooking temperature, can also include the sum obtained by adding the first temperature to the cooking temperature, and can also include the average value of the cooking temperature and the first temperature threshold, which is not limited herein; the second set temperature can include the difference obtained by subtracting the second temperature threshold from the cooking temperature, can also include the sum obtained by adding the second temperature to the cooking temperature, and can also include the average value of the cooking temperature and the second temperature threshold, which is not limited herein.

[0087] Among them, the first temperature is greater than the first set temperature, and the second temperature is greater than the second set temperature. It can be understood that the first temperature is greater than the difference obtained by subtracting the first temperature threshold from the cooking temperature, and the second temperature is greater than the difference obtained by subtracting the second temperature threshold from the cooking temperature; it can also be understood that the temperature in the first flushing stage of the cooking appliance exceeds the first flushing temperature. Correspondingly, the cooking appliance can control the heating parameters of the heating device to enter the next stage. For example, it can control the heating element including the electromagnetic heating element to continuously heat based on the target power, and control other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for the first preset duration at the first time interval, so as to ensure that the temperature in the cooking cavity is close to the cooking temperature and ensure the cooking effect of the cooking appliance on the food.

[0088] Exemplarily, the first temperature detection device includes an NTC1 detection circuit, the second temperature detection device includes an NTC2 detection circuit, the first heating element is a heating element including an IH electromagnetic heating element, and the second heating element is a heating element including a heating tube. Considering that the area where the IH electromagnetic heating element generates heat is larger than the area where the heating tube generates heat, correspondingly, the offset of the first temperature obtained as the cavity temperature in the middle of the cooking cavity is less than the offset of the second temperature obtained as the cavity temperature in the middle of the cooking cavity. In this embodiment, the second temperature threshold can be set to be greater than the first temperature threshold. For example, the first temperature threshold is set to be above 5°C, and the second temperature threshold is set to be above 10°C. Among them, the first temperature threshold can be understood as the offset temperature in the first flushing stage of the NTC1 detection circuit, and the second temperature threshold can be understood as the offset temperature in the first flushing stage of the NTC2 detection circuit.

[0089] Among them, the first time interval can be preset in the cooking appliance, and the cooking appliance can also obtain the first time interval from an associated electronic device or the cloud through wireless communication technology. Among them, the first time interval can be set independently by the user or obtained through third-party experimental data, which is not limited herein. For example, the first time interval is 4 seconds, 3 seconds, etc.

[0090] Among them, the first preset duration can be preset in the cooking appliance in advance, or the cooking appliance can obtain the first preset duration from an associated electronic device or the cloud through wireless communication technology. Among them, the first preset duration can be set independently by the user or obtained through third-party experimental data, which is not limited herein. Exemplarily, the first preset duration is 5 seconds, 6 seconds, etc.

[0091] Exemplarily, after the cooking appliance determines that the first temperature is greater than the first set temperature, or after determining that the second temperature is greater than the second set temperature, it can control other heating elements in the heating device except for the heating element including the IH electromagnetic heating element to heat at intervals of (x1, y1) based on the maximum power, where x1 can be used to represent the first preset duration, y1 can be used to represent the heating cycle, and the difference between y1 and x1 can be used to represent the first time interval. Among them, x1 can be set to more than 5 seconds; y1 can be set to more than 10 seconds.

[0092] Optionally, the target power can be determined according to the type of ingredients in the cooking cavity, or according to the weight of the food in the frying bucket, or according to the amount of water in the frying bucket. The target power is less than the maximum power of the heating element including the IH electromagnetic heating element, which is not limited herein. Exemplarily, the target power can be in the range of 20%-80% of the maximum power of the heating element including the IH electromagnetic heating element.

[0093] In some embodiments, the cooking appliance can receive a parameter setting instruction input by the user, and the parameter setting instruction can carry the type of ingredients. Among them, the corresponding relationship between the type of ingredients and the power can be preset in the cooking appliance; among them, the corresponding relationship can include a mapping table in which the type of ingredients and the power are in one-to-one correspondence, and can also include a mapping table in which the type of ingredients and the power are in many-to-one correspondence, which is not limited herein. Exemplarily, the power corresponding to the ingredient type of meat is greater than the power corresponding to the ingredient type of vegetables to determine the ingredient type of the food in the cooking cavity.

[0094] In some embodiments, the corresponding relationship between the weight and the power can be preset in the cooking appliance, where the corresponding relationship can include a mapping table in which the weight and the power are in one-to-one correspondence, and can also include a mapping table in which the weight and the power are in many-to-one correspondence, which is not limited herein. Exemplarily, if it is determined that the weight in the frying bucket is greater than the preset weight, the first power is used as the target power; if it is determined that the weight in the frying bucket is less than or equal to the preset weight, the second power is used as the target power, where the first power can be greater than the second power.

[0095] In some embodiments, a corresponding relationship between the water volume and the power may be preset in the cooking appliance. Among them, the corresponding relationship may include a mapping table in which the water volume and the power are in one-to-one correspondence, and may also include a mapping table in which multiple water volumes correspond to one power, which is not limited herein. Exemplarily, if it is determined that the water volume in the frying barrel is greater than the preset water volume, the third power is taken as the target power; if it is determined that the water volume in the frying barrel is less than or equal to the preset water volume, the fourth power is taken as the target power, where the third power may be greater than the fourth power.

[0096] In some embodiments, when the cooking appliance controls the heating element including the electromagnetic heating element to continuously heat based on the target power, and controls the other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for the first preset duration at the first time interval, it may also control the hot air blower to rotate. For example, control the hot air blower to rotate at a medium or high gear.

[0097] It can be understood that the cooking appliance controls the heating device to heat at the maximum power during the first flushing stage of cooking to quickly increase the temperature in the cooking cavity for food cooking and improve the cooking efficiency. During the first flushing stage, if the cooking appliance determines based on the first size relationship that the first temperature is greater than the first set temperature, or determines based on the second size relationship that the second temperature is greater than the second set temperature, it can control the heating element including the electromagnetic heating element to continuously heat based on the target power, and control the other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for the first preset duration at the first time interval, so as to control the cooking appliance to perform cooking in the temperature balance stage, so as to prevent the temperature in the cooking cavity from exceeding the cooking temperature and resulting in poor cooking effect of the food, and improve the cooking performance of the cooking appliance.

[0098] Among them, during the process of the cooking appliance entering the temperature balance stage from the first flushing stage, it can control the hot air blower to adjust and rotate the gear. For example, the cooking appliance can control the hot air blower to rotate at a medium or high gear, which is not limited herein.

[0099] Exemplarily, considering that the heating power of the heating device of the cooking appliance in the temperature balance stage is lower than that in the first flushing stage, in order to reduce the power consumption of the hot air blower and the loss of heat, the gear of the hot air blower can be lowered while the cooking appliance controls the cooking mode of the heating device to switch from the first flushing stage to the temperature balance stage. For example, if the gear of the hot air blower in the first flushing stage is high, the gear of the hot air blower can be controlled to be medium in the temperature balance stage.

[0100] In some embodiments, during the process of controlling the heating element including the electromagnetic heating element in the cooking appliance to continuously heat based on the target power, and controlling other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for the first preset duration at the first time interval, the first magnitude relationship or the second magnitude relationship can be obtained in real time.

[0101] As an implementable manner, after the cooking appliance controls the heating element including the electromagnetic heating element to continuously heat based on the target power, and controls other heating elements in the heating device except the heating element including the electromagnetic heating element to heat at the maximum power for the first preset duration at the first time interval, if it is determined based on the first magnitude relationship that the first temperature is greater than the third set temperature, or it is determined based on the second magnitude relationship that the second temperature is greater than the fourth set temperature, then the heating element including the IH electromagnetic heating element and other heating elements can be controlled to stop heating.

[0102] Among them, the third set temperature can be obtained according to the cooking temperature and the third temperature threshold; the fourth set temperature can be obtained according to the cooking temperature and the fourth temperature threshold. Among them, the fourth temperature threshold can be greater than the third temperature threshold.

[0103] Among them, the fact that the first temperature is greater than the third set temperature, or the second temperature is greater than the fourth set temperature can be understood as that the temperature of the cooking in the temperature balance stage of the cooking appliance exceeds the balanced heating temperature. Correspondingly, the cooking appliance can be controlled to enter the temperature reduction stage. For example, the heating device can be controlled to stop heating to ensure that the temperature in the cooking cavity does not exceed the temperature of the cooked food to avoid the food from being burnt.

[0104] Exemplarily, the first temperature detection device includes an NTC detection circuit, and the second temperature detection device includes an NTC detection circuit. Considering that the area where the IH electromagnetic heating element generates heat is larger than the area where the heating tube generates heat, correspondingly, the offset of the first temperature obtained as the cavity temperature in the middle of the cooking cavity is less than the offset of the second temperature obtained as the cavity temperature in the middle of the cooking cavity. In this embodiment, the fourth temperature threshold can be set to be greater than the third temperature threshold. For example, the fourth temperature threshold is set to be above 10 °C, and the third temperature threshold is set to be above 1 °C. Among them, the third temperature threshold can be understood as the offset temperature value of the set temperature of the NTC1 detection circuit, and the fourth temperature threshold can be understood as the offset temperature value of the set temperature of the NTC2 detection circuit.

[0105] In some embodiments, during the process of controlling the heating elements including the electromagnetic heating element and the other heating elements in the heating device to stop heating, the cooking appliance can control the rotation of the hot air blower included in the cooking appliance to accelerate the air flow in the cooking cavity, improve the temperature uniformity in the cooking cavity, so that the food in the cooking cavity is heated evenly, and improve the cooking performance of the cooking appliance. For example, the cooking appliance can control the hot air blower to rotate at medium, low or high gears.

[0106] Optionally, the cooking appliance can control the rotation of the hot air blower according to the menu performance of the cooking appliance, or according to the type of food ingredients, or according to the amount of water in the frying bucket, which is not limited herein. Among them, the cooking appliance can be pre-set with the corresponding relationship between the menu performance and the gear of the hot air blower, or the corresponding relationship between the type of food ingredients and the gear of the hot air blower, or the corresponding relationship between the amount of water and the gear of the hot air blower, which is not limited herein.

[0107] Exemplarily, a mapping relationship table in which the menu performance of the cooking appliance corresponds one-to-one with the gear of the hot air blower is pre-set in the cooking appliance. For example, fried chicken wings correspond to the high gear, baked egg tarts correspond to the medium gear, and French fries correspond to the low gear. If the cooking appliance determines that the menu performance is fried chicken wings, it can control the hot air blower to rotate based on the high gear.

[0108] In some embodiments, during the process of the cooking appliance controlling the heating elements including the electromagnetic heating element and the other heating elements to stop heating, the first size relationship or the second size relationship can be obtained in real time. Among them, after the cooking appliance controls the heating elements including the electromagnetic heating element and the other heating elements to stop heating, if it is determined based on the first size relationship that the first temperature is less than the fifth set temperature, or it is determined based on the second size relationship that the second temperature is less than the sixth set temperature, the heating element including the electromagnetic heating element can be controlled to continue heating based on the target power, and the other heating elements in the heating device except the heating element including the electromagnetic heating element can be controlled to heat at the maximum power for the first preset duration at the first time interval.

[0109] Among them, the fifth set temperature can be obtained according to the cooking temperature and the fifth temperature threshold, and the sixth set temperature can be obtained according to the cooking temperature and the sixth temperature threshold; among them, the sixth temperature threshold can be greater than the fifth temperature threshold. Considering that the heat generation area of the IH electromagnetic heating element is larger than the heat generation area of the heating tube, correspondingly, the offset of the first temperature obtained as the cavity temperature in the middle of the cooking cavity is smaller than the offset of the second temperature obtained as the cavity temperature in the middle of the cooking cavity. In this embodiment, the sixth temperature threshold can be set to be greater than the fifth temperature threshold. For example, the fifth temperature threshold is set to be above 2°C, and the sixth temperature threshold is set to be above 12°C. Among them, the fifth temperature threshold can be understood as the offset value of the working temperature recovery of the NTC1 detection circuit, and the sixth temperature threshold can be understood as the offset value of the working temperature recovery of the NTC2 detection circuit.

[0110] Among them, that the first temperature is less than the fifth set temperature, or the second temperature is less than the fourth set temperature can be understood as that the cooking temperature of the cooking appliance during the temperature reduction stage exceeds the reduced heating temperature, and the cooking appliance can be controlled to enter the temperature balance stage. For example, controlling the heating element including the electromagnetic heating element to continuously generate heat based on the target power, and controlling other heating elements in the heating device except the heating element including the electromagnetic heating element to generate heat at the maximum power for the first preset duration at the first time interval, so as to ensure the cooking effect of the temperature in the cooking cavity on the food and improve the cooking performance of the cooking appliance. Among them, the temperature controllability in the temperature balance stage is higher than that in the first charging stage. Controlling the cooking appliance to cook in the temperature balance stage ensures the accuracy of temperature control and also improves the cooking performance of the cooking appliance.

[0111] In this embodiment, the process of the cooking appliance in the cooking mode may include the first charging stage, the temperature balance stage, the temperature reduction stage, etc. The cooking appliance can control the heating parameters of the heating device according to the first temperature, the second temperature, and the cooking temperature, so that the cooking appliance circulates in the stages included in the cooking mode until the duration of the cooking appliance entering the cooking mode reaches the cooking duration, and then controls the cooking appliance to return to the standby mode, thereby improving the temperature control accuracy of the cooking appliance in the cooking mode, improving the temperature uniformity in the cooking cavity of the cooking appliance, and improving the cooking performance of the cooking appliance.

[0112] The cooking method provided by an embodiment of the present application, compared with Figure 3For the cooking method shown, in this embodiment, during the cooking duration, the first heating element or the second heating element can also be controlled to continuously heat based on the maximum power; obtain the temperature above the cooking cavity as the first temperature, or obtain the temperature of the bottom wall as the second temperature; according to the first magnitude relationship between the first temperature and the cooking temperature or the second magnitude relationship between the second temperature and the cooking temperature, control the heating parameters of the heating elements including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device except for the heating elements including the electromagnetic heating element, and then combine the real-time temperature in the cooking cavity and the cooking temperature to control the heating elements including the IH electromagnetic heating element in the heating device to generate a large area of heat and the other heating elements except for the heating elements including the IH electromagnetic heating element to heat and cooperate with each other, ensuring the balance of the temperature in the cooking cavity, improving the uniformity of the temperature in the cooking cavity, and improving the cooking performance of the cooking appliance.

[0113] Please refer to Figure 5 , Figure 5 which shows a schematic flowchart of the cooking method provided by an embodiment of the present application. This method is applied to the above-mentioned cooking appliance, and the following will elaborate in detail on Figure 5 the process shown. The cooking method may specifically include the following steps:

[0114] Step S310: During the process that the cooking appliance is in the cooking mode, obtain the cooking duration and the cooking temperature.

[0115] Step S320: During the cooking duration, control the first heating element or the second heating element to continuously heat based on the maximum power.

[0116] Step S330: Obtain the temperature above the cooking cavity as the first temperature, or obtain the temperature of the bottom wall as the second temperature.

[0117] Step S340: According to the first magnitude relationship between the first temperature and the cooking temperature or the second magnitude relationship between the second temperature and the cooking temperature, control the heating parameters of the heating elements including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device except for the heating elements including the electromagnetic heating element.

[0118] Among them, for the specific descriptions of steps S310 - S340, please refer to the specific descriptions of steps S210 - S240 in the previous text, and will not be elaborated one by one here.

[0119] Step S350: If the first temperature is greater than the first over-temperature protection temperature or the second temperature is greater than the second over-temperature protection temperature, then control the heating elements including the electromagnetic heating element and the other heating elements in the heating device except for the heating elements including the electromagnetic heating element to stop heating, and control the hot air blower included in the cooking appliance to blow air into the cooking cavity.

[0120] In some embodiments, the ultra-high temperature protection temperature of the first temperature detection device may be preset in the cooking appliance, and the cooking appliance may obtain this ultra-high temperature protection temperature as the first ultra-high temperature protection temperature; the ultra-high temperature protection temperature of the second temperature detection device may be preset in the cooking appliance, and the cooking appliance may obtain this ultra-high temperature protection temperature as the second ultra-high temperature protection temperature.

[0121] Optionally, the user may set the first ultra-high temperature protection temperature according to the ultra-high temperature protection temperature preset by the first temperature detection device, or may set the second ultra-high temperature protection temperature according to the ultra-high temperature protection temperature preset by the second temperature detection device. The cooking appliance may obtain the first ultra-high temperature protection temperature corresponding to the first temperature detection device through third-party experimental data, or may obtain the second ultra-high temperature protection temperature corresponding to the second temperature detection device through third-party experimental data.

[0122] In some embodiments, while the cooking appliance obtains the first temperature and the second temperature in real time, it may compare the real-time obtained first temperature with the first ultra-high temperature protection temperature, and compare the real-time obtained second temperature with the second ultra-high temperature protection temperature. If the first temperature is greater than the first ultra-high temperature protection temperature or the second temperature is greater than the second ultra-high temperature protection temperature, the first heating element and the second heating element may be controlled to stop heating, or all heating loads included in the cooking appliance may be controlled to stop working, so as to perform ultra-high temperature protection processing on the cooking appliance.

[0123] In some embodiments, after the cooking appliance controls all heating loads included in the cooking appliance to stop working, if it is determined that both the first temperature and the second temperature are lower than the working temperature threshold, the cooking appliance may be controlled to return to step S310 to perform a normal cooking program.

[0124] Among them, the working temperature threshold may be set independently by the user, or may be obtained through third-party experimental data; it may be preset in the cooking appliance, or may be obtained by the cooking appliance from an associated electronic device or the cloud. Exemplarily, the working temperature threshold may be below 105 °C.

[0125] Exemplarily, the first temperature detection device includes an NTC detection circuit. According to third-party experimental data, the ultra-high temperature protection temperature corresponding to the first temperature detection device is above 220°C. Further, the user can set the first over-temperature protection temperature to 220°C based on this ultra-high temperature protection temperature; the second temperature detection device includes a thermocouple detection circuit. According to third-party experimental data, the ultra-high temperature protection temperature corresponding to the second temperature detection device is above 220°C. Further, the user can set the first over-temperature protection temperature to 220°C based on this ultra-high temperature protection temperature. If the cooking appliance detects that the first temperature is greater than the first over-temperature protection temperature or the second temperature is greater than the second over-temperature protection temperature, it can control all the heating loads included in the cooking appliance to stop working and can output an alarm prompt for the user to cool down the cooking appliance based on this alarm prompt, such as adding water, opening the lid, etc. Correspondingly, after the cooking appliance controls all the heating loads to stop working, it can detect the first temperature and the second temperature in real time. If it is determined that both the first temperature and the second temperature are less than 105°C, it can control the cooking appliance to continue to control the heating parameters of the heating elements including the electromagnetic heating element and the heating parameters of the other heating elements in the heating device except the heating elements including the electromagnetic heating element according to the cooking duration and the cooking temperature, thereby ensuring cooking safety and improving the cooking performance of the cooking appliance.

[0126] The cooking method provided by an embodiment of the present application, compared with Figure 3 the cooking method shown, in this embodiment, if the first temperature is greater than the first over-temperature protection temperature or the second temperature is greater than the second over-temperature protection temperature, it can also control the heating elements including the electromagnetic heating element and the other heating elements in the heating device except the heating elements including the electromagnetic heating element to stop heating, and control the hot air blower included in the cooking appliance to blow air into the cooking cavity. Thus, during the process when the cooking appliance is in the cooking mode, it judges whether the temperature in the cooking cavity exceeds the over-temperature protection temperature, and when it exceeds, controls the heating device to stop heating, ensuring the safety of the cooking appliance. At the same time, it controls the heating elements including the electromagnetic heating element and the other heating elements in the heating device except the heating elements including the electromagnetic heating element to cooperate in heating, improving the temperature uniformity in the cooking cavity and the cooking performance of the cooking appliance.
