[0020] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0021] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only 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 making creative work are within the scope of protection of the present application.

[0022] As a cooking appliance, air fryers have become one of the important choices for home cooking. Air fryers have the advantages of fast heating and easy operation. However, current air fryers have the problem of uneven heating, especially in the corners of the air fryer, where the heat is weak and it is easy to produce heating blind spots, resulting in differences in the degree of doneness of food. If the heating time is increased, the food in other areas with higher temperatures may become burnt, which restricts the application of this type of cooking appliance.

[0023] Please refer to Figure 1, which shows a schematic diagram of a cooking appliance 100 provided by an embodiment of the present application. In the embodiment of the present application, the cooking appliance 100 has an air frying function. Air frying refers to a method of heating food by generating hot air through a heating tube and then quickly circulating the hot air in a sealed space through a hot air convection system. In the embodiment of the present application, the cooking appliance 100 may be an air fryer.

[0024] Please refer to Figure 2 , which shows a perspective view of a cooking appliance 100 provided by one embodiment of the present application. Figure 2 It can be seen that the cooking appliance 100 includes a shell 103, a frying bucket 101 and a heating chamber 102, wherein the frying bucket 101 can be disassembled so that it is convenient to take out when food needs to be placed or taken out, and the frying bucket 101 has a accommodating space, which forms at least a part of the heating chamber 102, and the upper part of the accommodating space is open.

[0025] The cooking device 100 further includes a first heating device 110, a second heating device 120 and a third heating device 130, wherein the first heating device 110, the second heating device 120 and the third heating device 130 can be arranged at intervals and used to heat different areas of the heating chamber 102. Specifically, in this embodiment, the first heating device 110 is arranged at the bottom of the frying vat 101, and is used to heat the bottom area of ​​the heating chamber 102. The first heating device 110 can be configured as an infrared heating plate, which is a disc-shaped heating coil structure. A ceramic panel can be arranged above the first heating device 110 to isolate the first heating device 110 and conduct heat. The first heating device 110 preferably adopts a medium output power form. For example, the output power of the first heating device 110 can be controlled at about 500W. It should be noted that in some other embodiments, the first heating device 110 can also adopt other heating device forms, such as a heating tube, a heating belt, etc., which is not limited in this embodiment.

[0026] The second heating device 120 can be arranged in the approximate middle area of ​​the frying vat 101, and in order to improve the uniformity of heating, the second heating device 120 can be configured as an annular structure and arranged along the circumference of the frying vat 101. In a more specific embodiment, the second heating device 120 can be a heating belt, and is configured to be arranged in an annular manner in the approximate middle area of ​​the frying vat 101. The second heating device 120 preferably adopts the form of mid-bottom output power, for example, the output power of the second heating device 120 can be controlled at about 150W. It should be noted that in some other embodiments, the second heating device 120 can also adopt other heating device forms, such as heating tubes, heating coils, etc., which are not limited in this embodiment.

[0027] The third heating device 130 is disposed at the top area of ​​the heating chamber 102, and is used to heat the top area of ​​the heating chamber 102. The third heating device 130 can be specifically disposed above the frying vat 101, and heats the heating chamber 102 from the opening of the accommodation space of the frying vat 101. The third heating device 130 can be a heating tube, and the third heating device 130 preferably adopts a high output power form, for example, the output power of the third heating device 130 can be controlled at about 1000W. It should be noted that in some other embodiments, the third heating device 130 can also adopt other heating device forms, such as a heating coil, a heating belt, etc., which is not limited in this embodiment.

[0028] The cooking appliance 100 may further include a temperature detection device and an electronic control device 160. The temperature detection device is used to detect the temperature in the heating chamber 102. The temperature detection device may be various types of temperature sensors, which are not limited in this embodiment. In one embodiment, there may be one temperature detection device, and the temperature detection device may be set in the middle of the heating chamber 102. In this embodiment, the temperature detection device includes a first temperature detection device 151 and a second temperature detection device 152. The first temperature detection device 151 is used to detect the first temperature near the first heating device 110. The first temperature detection device 151 may be set near the first heating device 110. Specifically, in this embodiment, the first temperature detection device 151 is configured at the bottom of the frying tub 101 and is approximately located at the center of the first heating device 110. The first temperature detection device 151 may be an NTC detection circuit, Figure 3 A circuit diagram of an NTC detection circuit is shown. Figure 3 In the embodiment, the resistor R46 is electrically connected to the electronic control device 160 to send the detected temperature information to the electronic control device 160 .

[0029] The second temperature detection device 152 is used to detect the second temperature in the heating chamber 102. In this embodiment, the second temperature detection device 152 is disposed above the frying vat 101 and adjacent to the third heating device 130. Because the third heating device 130 has a higher output power than the second heating device 120, the second temperature detection device 152 is disposed adjacent to the third heating device 130 to facilitate obtaining more accurate temperature information. The second temperature detection device 152 may be a temperature sensor.

[0030] The cooking appliance 100 may further include a fan 140, which is used to provide a circulating airflow in the heating chamber 102, so that the hot air circulates to all areas in the heating chamber 102, thereby improving the uniformity of heating. In this embodiment, since the third heating device 130 has a higher output power, it is used as the main heat source of the cooking appliance 100, so the fan 140 can be arranged in the top area of ​​the frying vat 101, adjacent to the third heating device 130, and is used to provide a circulating airflow toward the heating chamber 102. In this way, when the fan 140 is working, the heat generated by the third heating device 130 can be circulated to various places of the heating chamber 102 in the frying vat 101 by generating a circulating airflow, so that the heat is evenly dispersed in various places in the heating chamber 102. The fan 140 can have multiple working gears. Under different working gears, the fan 140 can provide different wind speeds and different wind volumes. According to different usage requirements, different working gears of the fan 140 can be selected to adjust the wind speed, wind volume, etc. In this embodiment, the number of the fan 140 is 1. In some other implementations, the number of fans 140 may be multiple, which is not limited in this embodiment.

[0031] The cooking appliance 100 further includes an electronic control device 160 ( Figure 3 ), the electric control device 160 is electrically connected to the first heating device 110, the second heating device 120, the third heating device 130, the temperature detection device and the fan 140, and is used to control the operation of the first heating device 110, the second heating device 120, the third heating device 130, the temperature detection device and the fan 140, specifically, to control the start or shutdown of the first heating device 110, the second heating device 120, the third heating device 130, the temperature detection device and the fan 140, and the working parameters when starting. In some embodiments, the electric control device can also be connected to the control panel on the housing 103. When the control panel receives an operation signal for any functional control, it generates a corresponding electrical signal and sends it to the electric control device 160. The electric control device 160 controls the cooking appliance 100 based on the electrical signal. In the embodiment of the present application, the electric control device 160 starts to execute the current cooking process after receiving the cooking instruction. Optionally, the electric control device 50 is a microcontroller unit (MCU).

[0032] Please refer to Figure 4 , which shows a flow chart of a control method for a cooking appliance provided by an embodiment of the present application. The method is applied to Figure 1 or Figure 2 The cooking appliance 100 is shown. The method comprises the following steps S110-S140.

[0033] S110, obtaining cooking instructions.

[0034] The cooking instruction is triggered by the user to instruct the cooking appliance to start the cooking process.

[0035] In some embodiments, a control panel is provided on the outer shell component of the cooking appliance, and the control panel includes a start control. After the cooking appliance obtains an operation signal for the start control, it obtains a cooking instruction. When the start control is a virtual control, the operation signal may be a single-click operation signal, a double-click operation signal, a sliding operation signal, etc.; when the start control is a physical control, the operation signal may be a single or multiple press operation signal. In some embodiments, the cooking instruction may also be issued by the cooking appliance through other devices in a wireless or wired communication manner. For example, the cooking appliance can be connected to a user's mobile terminal in communication, and the user can control the cooking instruction on the mobile terminal.

[0036] In other embodiments, the cooking appliance obtains the cooking instruction when the scheduled time arrives. The scheduled time is the time preset by the user when the cooking appliance is expected to start cooking. Optionally, the control panel of the cooking appliance also includes a reservation control. When the operation signal for the reservation control and the reservation duration input by the user are received, the cooking appliance obtains the cooking instruction when the scheduled time arrives. The time between the time when the cooking appliance obtains the reservation duration and the reservation time is the above-mentioned reservation duration.

[0037] The cooking instruction includes the set temperature and set time parameters, wherein the cooking instruction may be a preset menu instruction, for example, when the user selects a certain function, the set temperature and set time are preset in the function. The cooking instruction may also be a user-defined setting when issuing the cooking instruction. The cooking appliance may obtain the set temperature and set time involved in the current cooking process before or after obtaining the cooking instruction, wherein the set time may be the total heating time, and the set temperature may be the heating temperature of the heating chamber during the entire heating process, and the heating temperature may be fixed, and the heating temperature may also be different in different heating stages, for example, within the first preset time, the heating temperature is t1, within the second preset time after the first preset time, the heating temperature is t2, and within the third preset time after the second preset time, the heating temperature is t3. In one embodiment, t1, t2, and t3 may not be equal; in another embodiment, two or three of t1, t2, and t3 may be equal.

[0038] S120, in response to the cooking instruction, turning on the third heating device and preheating in the first mode for a first preset time.

[0039] The third heating device is turned on and can generate heat. The first mode, for example, can be that the third heating device heats with high power output, wherein the high power output can refer to that the third heating device heats with a power greater than or equal to 2 / 3 of its respective rated output power.

[0040] In this embodiment, the first mode is that the third heating device heats at full power. Heating at full power means that the third heating device heats at its respective rated output power. This heating method can not only maximize the heat output and the heating rate, but also make the third heating device work in a better state, which is conducive to extending the service life of the third heating device. It should be noted that the first mode can also be other forms of heating modes, which are not limited in this embodiment. For example, the first mode can also be intermittent heating by the third heating device.

[0041] By turning on the third heating device, the entire heating cavity can be evenly preheated, so that the temperature in the heating cavity is evenly increased, and the food is preheated. At this time, the temperature in the heating cavity has not yet reached the cooking temperature, and the food is preheated.

[0042] In some embodiments, step S120 further includes turning on the fan, so that the heat generated by the third heating device can form a hot air circulation in the entire heating chamber, thereby preheating the entire heating chamber. In the first preset time, the fan can be operated at a first wind speed, and the first wind speed can be, for example, the rated wind speed of the fan. In some other embodiments, the first wind speed can also be other wind speeds, which is not limited in this embodiment.

[0043] The first preset duration refers to a fixed time period after the third heating device is turned on, which can be 10 minutes, 5 minutes, etc., and is not limited here. In one embodiment, the first preset duration can be 2 / 5 of the total heating duration. In some other embodiments, the proportion of the first preset duration to the total heating duration can also be other values.

[0044] After the timing of step S120 ends, that is, the timing of the first preset time ends, step S130 is executed.

[0045] Step S130: Turn on the first heating device and the second heating device, control the first heating device to heat at a first set temperature, and control the third heating device to heat at a second set temperature; control the second heating device to heat in a second mode for a second preset time, and then heat at a third set temperature for a third preset time.

[0046] In step S120, the third heating device is turned on, and the heating cavity and the food are preheated. After entering step S130, the first heating device and the second heating device are turned on, and the first heating device and the second heating device start heating at the same time. Since the first heating device, the second heating device and the third heating device are set at different positions, the heat source in the entire heating cavity increases after heating at the same time, and the food is cooked.

[0047] The second preset duration refers to a fixed time period starting from the end of the first preset duration, which can be 10 minutes, 5 minutes, etc., and is not limited here. In one embodiment, the first preset duration can be 1 / 5 of the total heating duration. In some other embodiments, the proportion of the second preset duration to the total heating duration can also be other values.

[0048] The third preset duration refers to a fixed time period starting from the end of the second preset duration, which can be 10 minutes, 5 minutes, etc., and is not limited here. In one embodiment, the first preset duration can be 2 / 5 of the total heating duration. In some other embodiments, the proportion of the third preset duration to the total heating duration can also be other values.

[0049] Among them, during the entire time period of the second preset time length and the third preset time length, the first heating device is controlled to heat at the first set temperature, and the third heating device is controlled to heat at the second set temperature, that is, during the entire time period of the second preset time length and the third preset time length, the first heating device and the third heating device both maintain the set temperature for heating.

[0050] The first set temperature and the second set temperature may be heating temperatures determined according to different ingredients, and the first set temperature and the second set temperature may be obtained from the cooking instructions in step S110, for example, the cooking appliance may have built-in cooking programs for different ingredients, and the cooking programs may include the first set temperature and the second set temperature. The first set temperature and the second set temperature may also be set by the user, for example, the user may input the first set temperature and the second set temperature by operating a human-computer interaction interface set on the cooking appliance, or may input the first set temperature and the second set temperature through a mobile terminal (such as a mobile phone) that is connected to the cooking appliance for communication.

[0051] It should also be noted that, in a more specific embodiment, the first set temperature and the second set temperature may be equal. Of course, in some other embodiments, the first set temperature and the second set temperature may not be equal.

[0052] The second mode may be, for example, that the second heating device performs heating in a manner of high power output, wherein the high power output may refer to that the second heating device outputs power greater than or equal to 2 / 3 of its respective rated output power.

[0053] In this embodiment, the second mode is that the second heating device heats at full power. The full power heating means that the third heating device heats at its respective rated output power. This heating mode can not only maximize the heat output and the heating rate, but also make the second heating device work in a better state, which is conducive to extending the service life of the second heating device. It should be noted that the second mode can also be other forms of heating modes, which are not limited in this embodiment. For example, the second mode can also be intermittent heating by the second heating device. Since the second heating device is located in the middle area of ​​the heating chamber, during the heating process, the second heating device performs high-power heating output, which can quickly heat the food, speed up the cooking progress of the food, shorten the cooking time, and cooperate with the first heating device and the third heating device to heat and stew the food in three dimensions. At the same time, since the first heating device and the third heating device are heated according to a fixed set temperature, during the heating process, the output power of the first heating device and the third heating device will change with the actual temperature in the heating chamber, so when heating the top and bottom of the food, excessive water loss of the food can be avoided.

[0054] After the second preset time period ends, the second heating device heats the food at a third set temperature for a third preset time period. The third set temperature may be a heating temperature determined according to different ingredients. The third set temperature may be obtained from the cooking instruction in step S110. For example, the cooking appliance may have built-in cooking programs for different ingredients, and the cooking programs may include the third set temperature. The third set temperature may also be set by the user. For example, the user may input the third set temperature by operating a human-computer interaction interface set on the cooking appliance, or may input the third set temperature through a mobile terminal (such as a mobile phone) that is connected to the cooking appliance for communication.

[0055] It should also be noted that, in a more specific embodiment, the first set temperature, the second set temperature and the third set temperature may be equal. Of course, in some other embodiments, the first set temperature, the second set temperature and the third set temperature may not be equal.

[0056] During the third preset time, the second heating device heats at the third set temperature, and the output power of the second heating device changes with the actual temperature in the heating chamber, so when heating the inside of the food, excessive water loss of the food can be avoided. In conjunction with the first heating device and the third heating device, the surface of the food can be quickly and evenly colored without burning.

[0057] During the heating process of the second preset time, the fan can still run at the first wind speed, thereby achieving more efficient hot air circulation in the heating chamber, improving the heating and cooking efficiency, and avoiding the occurrence of local high temperature areas to prevent the food from being burnt. At the same time, in one embodiment, during the heating process of the third preset time, the fan can run at the second wind speed, wherein the first wind speed can be greater than the second wind speed. During the heating process of the third preset time, by appropriately adjusting the wind speed of the fan, it can match the heat output of the first heating device, the second heating device, and the third heating device, to achieve more efficient heating and cooking.

[0058] Step S140: turning off the first heating device, the second heating device and the third heating device.

[0059] After the third preset time is over, the first heating device, the second heating device and the third heating device are turned off, and the residual heat in the heating chamber is used to keep the food warm. During this process, the fan can continue to be turned on or off.

[0060] The control method, device, cooking device and storage medium of the cooking appliance provided in the embodiments of the present application first use the third heating device to uniformly preheat the entire heating chamber within a first preset time during the heating process, so that the heat is evenly diffused in the heating chamber, and then within a second preset time, the first heating device, the second heating device and the third heating device are simultaneously turned on to heat the food in three dimensions, so that the food is heated more evenly and the degree of cooking is more uniform, and then within the third preset time, the second heating device is controlled to adjust the set temperature to quickly heat and color the surface and bottom of the food, so that the heating state of the food finally cooked is more uniform.

[0061] It should also be noted that during the execution of step S120 and step S130, the first temperature detection device can detect the first temperature near the first heating device in real time, and the second temperature detection device can detect the second temperature in the heating chamber in real time. When the first temperature is greater than or equal to the first preset temperature, and / or the second temperature is greater than or equal to the second preset temperature, the first heating device, the second heating device and the third heating device are turned off, and the fan can be started at the same time to cool down the heating chamber. The first preset temperature and the second preset temperature are both high temperature protection temperatures to prevent the food from being burnt due to excessive temperature, or even causing the cooking utensils to be damaged due to high temperature.

[0062] Exemplarily, the first preset temperature may be, for example, 220°C, and the second preset temperature may be, for example, 370°C.

[0063] Further, after the first heating device, the second heating device, and the third heating device are turned off, the first temperature and / or the second temperature may continue to be acquired, and if the first temperature is less than the third preset temperature, and / or the second temperature is less than the fourth preset temperature, step S120 or step S130 may be resumed. Exemplarily, the first preset temperature may be, for example, 120°C, and the second preset temperature may be, for example, 200°C.

[0064] By setting the first preset temperature, the second preset temperature, the third preset temperature and the fourth preset temperature, the cooking utensils can be better protected, damage to the cooking utensils caused by abnormal heating can be avoided, and food ingredients can be prevented from being burned due to abnormal heating.

[0065] See also Figure 5 , Figure 5 A flow chart of another cooking appliance control method provided by an embodiment of the present application is shown, wherein the temperature detection device in the cooking appliance may include a first temperature detection device and a second temperature detection device, the first temperature detection device is used to detect a first temperature near the first heating device, and the second temperature detection device is used to detect a second temperature in the heating cavity. The cooking appliance control method includes steps S210-S270.

[0066] Step S210: receiving cooking instructions.

[0067] Step S220: In response to the cooking instruction, turn on the third heating device and preheat in the first mode for a first preset time.

[0068] Step S230: Turn on the first heating device and the second heating device.

[0069] Step S240: Obtain the first temperature, determine the temperature difference between the first temperature and the first set temperature, determine the output power of the first heating device according to the mapping relationship between the preset temperature difference between the first temperature and the first set temperature and the output power; control the first heating device to heat according to the determined output power.

[0070] Among them, the first temperature refers to the temperature near the first heating device, which can be obtained by the first temperature detection device. The first set temperature is the temperature set by the user when using the cooking utensil. In some embodiments, the first set temperature can be a user-defined setting, and in other embodiments, the first set temperature is a cooking temperature preset in a cooking program selected by the user. During the actual heating process, the first temperature fluctuates, so in order to make the deviation between the temperature in the entire heating cavity and the first set temperature within a controllable range, it is necessary to continuously adjust the output power of the first heating device.

[0071] Specifically in this embodiment, the mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power means that the greater the temperature difference between the first temperature and the first set temperature, the greater the change in the output power needs to be, and the smaller the temperature difference between the first temperature and the first set temperature, the smaller the change in the output power is or even does not need to be changed. The mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power can be pre-acquired and stored locally, or can be pre-stored in a server, and when it needs to be called, a download request is sent to the server, and the download is executed.

[0072] Exemplarily, as shown in Table 1, this embodiment shows a mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power.

[0073] Table 1 Mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power

[0074]

[0075] In Table 1, power refers to the ratio of output power to rated power. For example, when the temperature difference between the first temperature and the first set temperature is greater than 18°C, the output power is 90% of the rated power. For another example, when the temperature difference between the first temperature and the first set temperature is greater than 4°C and less than 8°C, the output power is 50% of the rated power. It can be understood that the above-mentioned mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power is only used as an example. In some other embodiments, the mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power can also be in other forms.

[0076] After obtaining the first temperature, the temperature difference between the first temperature and the first set temperature can be determined. By querying the mapping relationship between the temperature difference between the first temperature and the first set temperature and the output power, the corresponding output power value can be obtained. According to the output power value, the first heating device is controlled to adjust the output power in real time according to the output power value. In this way, the temperature difference between the first temperature and the first set temperature can be smaller, and the entire cooking process can be carried out in a uniform and stable temperature field.

[0077] Step S250: Obtain the second temperature, determine the temperature difference between the second temperature and the second set temperature, determine the output power of the third heating device according to the mapping relationship between the preset temperature difference between the second temperature and the second set temperature and the output power; control the third heating device to heat according to the determined output power.

[0078] Among them, the second temperature refers to the temperature in the heating cavity, which can be obtained by the second temperature detection device. The second set temperature is the temperature set by the user when using the cooking utensil. In some embodiments, the second set temperature can be a user-defined setting, and in other embodiments, the second set temperature is a cooking temperature preset in the cooking program selected by the user. During the actual heating process, the second temperature fluctuates. Therefore, in order to make the deviation between the temperature in the entire heating cavity and the second set temperature within a controllable range, it is necessary to continuously adjust the output power of the third heating device. It should also be noted that the first set temperature and the second set temperature can be equal.

[0079] Specifically in this embodiment, the mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power means that the greater the temperature difference between the second temperature and the second set temperature, the greater the change in the output power needs to be, and the smaller the temperature difference between the second temperature and the second set temperature, the smaller the change in the output power is or even does not need to be changed. The mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power can be pre-acquired and stored locally, or can be pre-stored in a server, and when it needs to be called, a download request is sent to the server, and the download is executed.

[0080] Exemplarily, as shown in Table 2, this embodiment shows a mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power.

[0081] Table 2 Mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power

[0082]

[0083]

[0084] In Table 2, power refers to the ratio of output power to rated power. For example, when the temperature difference between the second temperature and the second set temperature is greater than 18°C, the output power is 90% of the rated power. For another example, when the temperature difference between the second temperature and the second set temperature is greater than 4°C and less than 8°C, the output power is 50% of the rated power. It can be understood that the above-mentioned mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power is only used as an example. In some other embodiments, the mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power can also be in other forms.

[0085] After obtaining the second temperature, the temperature difference between the second temperature and the second set temperature can be determined. By querying the mapping relationship between the temperature difference between the second temperature and the second set temperature and the output power, the corresponding output power value can be obtained. According to the output power value, the third heating device is controlled to adjust the output power in real time according to the output power value. In this way, the temperature difference between the second temperature and the second set temperature can be smaller, and the entire cooking process can be carried out in a uniform and stable temperature field.

[0086] It can be understood that step S240 and step S250 are performed simultaneously and there is no order of precedence.

[0087] Step S260: Control the second heating device to heat at full power for a second preset time, and then heat at a third set temperature for a third preset time.

[0088] While step S240 and step S250 are being executed, in step S260, the second heating device first heats at full power for a second preset time. During the second preset time, the second heating device heats at rated output power. Since the second heating device is located in the middle area of ​​the heating chamber, when the second heating device heats at full power, it cooperates with the first heating device and the third heating device to adjust the output power in real time according to temperature changes during the heating process, thereby keeping the temperature field in the entire heating chamber uniform and stable, thereby performing all-round three-dimensional heating of the ingredients, so that the food can be quickly cooked.

[0089] After the second preset time ends, the second heating device is controlled to heat at a third set temperature for the third preset time. In some embodiments, the third set temperature may be a user-defined setting, and in other embodiments, the third set temperature is a cooking temperature preset in a cooking program selected by the user. It should also be noted that the first set temperature, the second set temperature, and the third set temperature may be equal or unequal.

[0090] Within the third preset time, most of the ingredients are already cooked. At this time, the second heating device is adjusted from full-power heating to heating according to the third set temperature, which can make the surface of the ingredients quickly and evenly colored, ensuring the appearance and flavor of the processed ingredients.

[0091] Specifically, in a more specific embodiment, step S260 can be performed in the following manner: control the second heating device to heat at full power for a second preset time; after the second preset time, obtain the second temperature, determine the temperature difference between the second temperature and the third set temperature, and determine the output power of the second heating device based on the mapping relationship between the temperature difference between the preset second temperature and the third set temperature and the output power; control the second heating device to heat for the third preset time based on the determined output power.

[0092] During the actual heating process, the second temperature fluctuates. Therefore, in order to make the deviation between the temperature in the entire heating chamber and the third set temperature within a controllable range, the output power of the second heating device needs to be continuously adjusted.

[0093] Specifically in this embodiment, the mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power means that the greater the temperature difference between the second temperature and the third set temperature, the greater the change in the output power needs to be, and the smaller the temperature difference between the second temperature and the third set temperature, the smaller the change in the output power is or even does not need to be changed. The mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power can be pre-acquired and stored locally, or can be pre-stored in a server, and when it needs to be called, a download request is sent to the server, and the download is executed.

[0094] Exemplarily, as shown in Table 3, this embodiment shows a mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power.

[0095] Table 3 Mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power

[0096]

[0097] In Table 3, power refers to the ratio of output power to rated power. For example, when the temperature difference between the second temperature and the third set temperature is greater than -7°C, the output power is 150% of the rated power. For another example, when the temperature difference between the second temperature and the second set temperature is greater than -4°C and less than -5°C, the output power is 90% of the rated power. It can be understood that the above-mentioned mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power is only used as an example. In some other embodiments, the mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power can also be in other forms.

[0098] After obtaining the second temperature, the temperature difference between the second temperature and the third set temperature can be determined. By querying the mapping relationship between the temperature difference between the second temperature and the third set temperature and the output power, the corresponding output power value can be obtained. According to the output power value, the second heating device is controlled to adjust the output power in real time according to the output power value. In this way, the temperature difference between the second temperature and the third set temperature can be smaller, and the entire cooking process can be carried out in a uniform and stable temperature field.

[0099] By controlling the output power of the second heating device in real time, the heating process within the third preset time period can be finely controlled to ensure that the heat in the heating chamber is moderate so that the food is evenly colored.

[0100] In some other implementations, step S260 may also adopt a variable temperature adjustment method, for example, heating is performed for a predetermined time period t1 and a duration t2, which is not limited in this embodiment.

[0101] It should also be noted that step S240, step S250 and step S260 are performed simultaneously without any order. That is, step S240 and step S250 perform the same operation during the second preset time and the third preset time. In particular, in a more specific embodiment, the second preset time may be 1 / 5 of the total cooking time, and the third preset time may be 2 / 5 of the total cooking time.

[0102] After the third preset time period ends, step S270 is executed.

[0103] Step S270: turning off the first heating device, the second heating device and the third heating device.

[0104] The control method, device, cooking device and storage medium of the cooking utensil provided in the present embodiment first use the third heating device to uniformly preheat the entire heating cavity within the first preset time period during the heating process, so that the heat is evenly diffused in the heating cavity, and then within the second preset time period, the first heating device, the second heating device and the third heating device are simultaneously turned on to perform three-dimensional heating of the food, so that the food is heated more evenly and the degree of stewing is more uniform, and then within the third preset time period, the second heating device is controlled to adjust the set temperature to quickly heat and color the surface and bottom of the food, so that the heating state of the finally cooked food is more uniform.

[0105] In addition, during the simultaneous execution of step S240, step S250 and step S260, the fan can remain on so that heat circulates in the heating chamber to avoid local high temperature in the heating chamber, ensuring that the food can be heated evenly without burning.

[0106] As a more specific implementation, during the second preset time, the fan is controlled to run at a first wind speed, and during the third preset time, the fan is controlled to run at a second wind speed, wherein the first wind speed is greater than or equal to the second wind speed. During the third preset time, by reducing the wind speed of the fan, the heat flow rate in the heating chamber is slowed down, which is conducive to quickly coloring the food.
