[0018] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution 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.

[0019] Please refer to Figure 1 and Figure 2 The embodiment of the present application provides an air fryer 100, which includes a cooking cavity 110, a hot air component, a first heating device 120, a second heating device 130 and a temperature detection device 140. The first heating device 120 and the second heating device 130 are arranged on a first side of the cooking cavity 110, and the second heating device 130 is sleeved on the first heating device 120. The hot air component is arranged on a second side of the cooking cavity 110, the first heating device 120 and the second heating device 130 are arranged opposite to the hot air component, and the temperature detection device 140 is used to detect the working temperature in the cooking cavity 110.

[0020] Conventional air fryers generally adopt a single heat source heating solution, that is, there is only a hot air component. This heating solution usually has the problem of uneven bottom heating. Therefore, in the present application, the first heating device 120 and the second heating device 130 can be controlled to heat synchronously during the heating process to quickly increase the heating temperature in the cooking cavity 110, thereby improving the food cooking efficiency.

[0021] The first heating device 120 and the second heating device 130 may also be controlled to heat alternately, so that the hot air flow inside the cooking cavity 110 can be accelerated during the heating process of the first heating device 120 and the second heating device 130, thereby improving the uniformity of heating.

[0022] Specifically, the cooking cavity 110 can be used to detachably place a container for holding food. When the first heating device 120 and the second heating device 130 are heated alternately, the temperatures of the areas in the cooking cavity 110 that are opposite to the first heating device 120 and the second heating device 130 are also different. The temperature difference will promote the flow of hot air in the cavity, thereby improving the uniformity of cooking.

[0023] In addition, alternating heating can also prevent the bottom from overheating and burning, thereby improving the user experience.

[0024] In some embodiments, a control panel is provided on the outer surface of the cooking cavity 110 or the surface of the top plate away from the bottom cover, and the control panel includes one or more functional controls, including but not limited to start controls, reservation controls, time setting controls, mode setting controls, food type setting controls, etc.

[0025] In some embodiments, the working status of the first heating device 120 and the second heating device 130 can be controlled by the control device 150, that is, the control device 150 can receive the cooking instructions sent by the control panel to control the heating mode of the first heating device 120 and the second heating device 130. The above-mentioned control device 150 can also include a communication module, which can be a Bluetooth module, a wifi module, etc. The user terminal can communicate with the air fryer through the above-mentioned communication module, so as to use the user terminal to send cooking instructions to the control device 150, so that the control device 150 controls the heating mode of the first heating device 120 and the second heating device 130 based on the cooking instructions.

[0026] The first heating device 120 may be a heating plate, which may be formed by winding a heating tube, or a plurality of heating tubes arranged side by side, or a plurality of local heaters arranged in sequence and spaced apart. The shape and size of the heating plate may be adapted to the shape and size of the bottom of the food container.

[0027] The second heating device 130 may include a plurality of local heaters, and when the first heating device 120 is a heating plate, the plurality of local heaters are disposed on the periphery of the first heating device 120 .

[0028] The second heating device 130 may also be a heating ring, which may be formed by a heating tube arranged in a winding manner, or by a plurality of heating tubes arranged side by side, or by a plurality of local heaters arranged at intervals.

[0029] like Figure 3 As shown, exemplarily, when the second heating device 130 is a heating ring and the first heating device 120 is a heating disk, the shape formed by the heating ring is adapted to the shape of the heating disk. Exemplarily, if the heating ring is a circular ring, the heating disk is a circular disk, and if the heating disk is a square ring, the heating disk is a square disk. The inner diameter of the heating ring can be slightly smaller than the outer diameter of the heating disk, or can be greater than or equal to the outer diameter of the heating disk.

[0030] Exemplarily, the first heating device 120 and the second heating device 130 are arranged at the bottom of the cooking cavity 110. If the bottom cross-sectional shape of the container is circular, the first heating device 120 can be a circular heating plate, and the size of the circular heating plate is adapted to the size of the bottom of the container; if the bottom cross-sectional shape of the container is square, the first heating device 120 can be a square heating plate, and the size of the square heating plate is adapted to the size of the bottom cross-sectional size of the container.

[0031] In one possible implementation mode of the application, the second heating device 130 is a heating ring and the heating ring is a circular ring, the first heating device 120 is a heating disk and the heating disk is a circular disk, and the inner diameter of the heating ring is greater than or equal to the outer diameter of the heating disk.

[0032] The temperature detection device 140 can be disposed at any position in the cooking cavity 110, such as the top, bottom, side wall, etc. of the cooking cavity 110. The temperature detection device 140 can be one or more. If there are more than one temperature detection device 140, the temperature detection devices 140 can be disposed at different positions in the cooking cavity 110 to detect the heating temperature at different positions in the heating wall.

[0033] In one possible implementation of the present application, the temperature detection device 140 is disposed in the cooking cavity 110 near the first heating device 120, and is used to detect the temperature near the first heating device 120. In order to use the control component to control the working state of the first heating device 120 and the second heating device 130, in one possible implementation of the present application, the control device 150 may include a controller and a driving circuit, and the driving circuit may be used to drive and control the working state of the first heating device 120 and the second heating device 130.

[0034] Specifically, Figure 4 , which is a circuit diagram of a driving circuit provided in an embodiment of the present application, wherein the driving circuit includes a first driving circuit for controlling the working state of the first heating device 120 and a second driving circuit for controlling the working state of the second heating device 130 .

[0035] The first driving circuit includes a first selection circuit and a first control circuit, wherein the first selection circuit includes: Figure 4 The resistor, capacitor and transistor connected as shown, the first control circuit includes Figure 4 The relay and the voltage-stabilizing diode are connected, wherein one end of the relay in the first control circuit is used to be connected to the live wire of the AC power, and the other end (ACL1) is connected to the first heating device, wherein the REL-1 end of the first selection circuit is connected to the controller and is used to be turned on when receiving a high-level signal output by the controller, so that the relay in the first control circuit is turned on, thereby controlling the first heating device to start heating.

[0036] The second driving circuit includes a second selection circuit and a second control circuit. The second selection circuit includes Figure 4 The resistor, capacitor and transistor connected as shown, the second control circuit includes Figure 4 A relay and a voltage-stabilizing diode are connected, wherein one end of the relay in the second control circuit is used to be connected to the live wire of the AC power, and the other end is connected to the second heating device, wherein the REL-2 end of the second selection circuit is connected to the controller, and is used to be turned on when a high-level signal output by the controller is received, so that the relay in the second control circuit is turned on, thereby controlling the second heating device to start heating.

[0037] It should be understood that the above-mentioned circuit schematic diagram of the driving circuit is only for illustration, and there may be other circuit implementation methods, which will not be described one by one in this application.

[0038] By adopting the above-mentioned setting of the present scheme, when the control device 150 controls the first heating device and the second heating device to heat the food in the food container, the heating states of the first heating device and the second heating device can be controlled to be inconsistent, so that hot air is formed in the cooking cavity 110 and flows through the gap between the cooking cavity 110 and the container arranged in the cooking cavity 110, so as to improve the uniformity of heating of the food when the cooking cavity 110 is used to heat the food, and avoid the situation where some food is undercooked and some food is overcooked due to uneven heating of the food. Therefore, by adopting the above-mentioned setting of the present application, the flavor of the food obtained by heating the food can be better.

[0039] In addition, by adopting the above-mentioned arrangement of the present application, it is also possible to avoid the situation where the four corners cannot be heated evenly when the container is a square container. That is, by adopting the above-mentioned scheme of the present application, when the heating states of the first heating device and the second component are controlled inconsistently, the positions corresponding to the four corners can all be maintained in a heated state, and because the heated temperatures of the four corners usually cannot reach the heated temperature of the center position when the clock remains in a heated state, therefore, the heating temperature of the four corners will not be too high while they are maintained in a heated state, thereby further improving the uniformity of food heating.

[0040] In order to further evenly heat the food in the container, in one possible implementation mode of the present application, the control device 150 is also used to control the working states of the first heating device and the second heating device according to the detected temperature.

[0041] The temperature detection device may be a temperature detection sensor, or any device capable of temperature detection, such as a thermocouple. The temperature detection device may be disposed near the first heating device, near the second heating device, or at any position of the cooking cavity 110.

[0042] In order to achieve accurate control of the heating effect of the first heating device and to improve the uniformity of heating food using the first heating device, in one possible implementation of the present application, the temperature detection device is a galvanic detection device, and the galvanic detection device is disposed in the first heating device.

[0043] Specifically, in this embodiment, the first heating device is a heating plate, and the thermocouple detection device is arranged at the center of the heating plate to detect the heating temperature at the center of the heating plate in the cooking cavity 110 .

[0044] In order to ensure the accuracy of the temperature obtained by the thermocouple detection device, in one embodiment of the present application, the control device 150 includes a controller and a thermocouple detection circuit. The specific circuit principle of the thermocouple detection circuit can be found in Figure 5As shown, CN2 in the circuit is used to connect to the thermocouple, the THERM_AD terminal is used to connect to the port of the controller, and the thermocouple detection circuit is specifically used to amplify the signal detected by the thermocouple, that is, the thermocouple detector can include Figure 5 The amplifier, resistor, capacitor and other components connected as shown in the figure, the parameters of the above components can be specifically set according to the actual required magnification, and are not specifically limited in this application, and can be selected according to actual needs. It should be understood that the circuit structure of the above-mentioned thermocouple detection circuit is only schematic, as long as it can achieve the amplification of the voltage value detected by the thermocouple, there can be other circuit implementation methods, which will not be described one by one in the embodiments of this application.

[0045] In order to further improve the uniformity of heating of the food placed in the container, in one embodiment of the present application, the temperature detection device 140 includes a first temperature detection device and a second temperature detection device, and the air fryer 100 also includes a third heating device 160 and a fourth heating device 170; the third heating device 160 is arranged at the top of the cooking cavity 110, the first temperature detection device is arranged at a position close to the first heating device 120 in the cooking cavity 110, and is used to detect the temperature near the first heating device 120 to obtain a first measured temperature, and the third heating device 160 is arranged at the top of the cooking cavity 110. At the top, the fourth heating device 170 is arranged on the inner wall of the cooking cavity 110; the second thermometer is arranged at a position of the cooking cavity 110 close to the third heating device 160 to detect the second measured temperature near the third heating device 160, and the control device 150 is also used to determine the first real-time temperature according to the first measured temperature and the first conditional temperature, and determine the second real-time temperature according to the second measured temperature and the second adjusted temperature, and determine the working temperature of the cooking cavity 110 according to the first real-time temperature and the second temperature, so as to control the heating mode of each heating device according to the working temperature of the cooking cavity 110.

[0046] The third heating device 160 may be a heating plate, a heating strip, or a local heating element. When the third heating device 160 is a heating strip or a local heating element, the heating strip or local heating element may be one or more. When there are multiple heating strips or local heating elements, the multiple heating strips or local heating elements are arranged at intervals on one side of the cooking cavity 110 near the top of the food container. When the third heating device 160 is a heating plate, the heating plate may be arranged on one side of the cooking cavity 110 near the top of the food container.

[0047] The fourth heating device 170 may be a heating plate, a heating strip, or a local heating element. When the fourth heating device 170 is a heating plate or a heating strip, the heating plate or the heating strip may be arranged on the inner side wall of the cooking cavity 110 and extend along the circumference of the cooking cavity 110, and the heating plate or the heating strip may be located near the middle or lower middle part of the food container. When the fourth heating device 170 includes a local heating element, there may be multiple local heating elements, and the multiple local heating elements may be arranged on the inner side wall of the cooking cavity 110 and arranged in sequence along the circumferential extension direction of the cooking cavity 110. Each of the local heating elements is located near the food container or the lower middle part of the food container.

[0048] By adopting the above-mentioned settings for the third heating device 160 and the fourth heating device 170, the air fryer 100 can simultaneously use one or more of the first heating device 120, the second heating device 130, the third heating device 160 and the fourth heating device 170 to heat the food in the food container, so as to effectively improve the uniformity of heating of the food.

[0049] The above-mentioned heating elements can be the same or different, and each heating element can be composed of an infrared heating tube, a heating resistance wire, or any device that can heat food, as long as it can heat food. In one embodiment of the present application, the first heating device 120, the second heating device 130, the third heating device 160, and the fourth heating device 170 are infrared heating tubes.

[0050] In order to further heat the food in the food container more evenly during the heating process, in one possible implementation of the present application, the air fryer 100 may further include a fan, and the fan may be disposed in the cooking cavity 110 .

[0051] Specifically, the fan can be set at the top, side wall or bottom of the cooking cavity 110 to make the air in the cooking cavity 110 flow further through the air passage, thereby making the temperature of the air in different parts of the cooking cavity 110 tend to be consistent, so that the food in the food container can be heated evenly.

[0052] Exemplarily, the above-mentioned fan can be set at the top of the cooking cavity 110. Since hot air moves upward when heated, by setting the fan at the top, the power of the fan can be used to make the hot air flow downward, so as to further accelerate the speed at which the air temperature in the cooking cavity 110 tends to be consistent.

[0053] Among them, the fan can be driven by a motor to rotate the fan blades to blow air, and can include multiple gears, such as high gear (speed above 2500rpm / min), medium gear (speed of 0-2500rpm / min), low gear (speed below 0rpm / min), etc. Exemplarily, the fan can include a fan with parameters of DC220V, 50Hz, and 1000W.

[0054] In which, when the air fryer includes a hot air blower, the control device 150 is connected to the hot air blower and is used to control the working parameters of the hot air blower, such as controlling the rotation speed, rotation time, etc. of the hot air blower.

[0055] It should be understood that the above-mentioned air fryer may also have more components or functional devices, which can be configured according to actual needs, and will not be described one by one in the embodiments of the present application.

[0056] See also Figure 6 As shown, the embodiment of the present application also provides a cooking control method, which can be applied to the above-mentioned air fryer, and the method includes:

[0057] Step S210: receiving a cooking instruction, wherein the cooking instruction includes a first set temperature and a set duration.

[0058] In some embodiments, the air fryer may include working modes such as a cleaning mode, a cooking mode, a warm-keeping mode, and a standby mode. In the warm-keeping mode, the air fryer may control the coordinated heating of the first heating device, the second heating device, and the third heating device 160 included in the air fryer to keep the food placed in the air fryer warm at a precise temperature; in the cooking mode, the air fryer may cook the food placed in the air fryer; in the standby mode, the components included in the air fryer may be in a standby state, and the air fryer may receive a control instruction input by a user and switch the working mode of the air fryer based on the control instruction.

[0059] The cooking instruction is triggered by the user to instruct the air fryer to start the cooking process. Specifically, it can be triggered by the user through a control panel or a terminal.

[0060] In some embodiments, a control panel is provided on the housing component of the air fryer, and the control panel includes a start control. After the air fryer 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 air fryer through other devices in a wireless or wired communication mode. For example, the air fryer can be connected to the user's mobile terminal in communication, and the user can control the cooking instruction on the mobile terminal.

[0061] In other embodiments, the air fryer obtains the cooking instruction when the scheduled time arrives. The scheduled time is the time preset by the user when the air fryer is expected to start cooking. Optionally, the control panel of the air fryer also includes a reservation control. When the air fryer receives an operation signal for the reservation control and the reservation duration input by the user, the air fryer obtains the cooking instruction when the scheduled time arrives. The time between the time when the air fryer obtains the reservation duration and the scheduled time is the above-mentioned reservation duration.

[0062] 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 function, the set temperature and set time are preset in the function. The cooking instruction may also be set by the user when issuing the cooking instruction. The air fryer may obtain the set temperature and set time involved in the current cooking process before or after obtaining the cooking instruction.

[0063] The set temperature refers to a temperature suitable for heating food. Different foods or dishes may correspond to different set temperatures, that is, the set temperature value is set according to actual cooking needs.

[0064] Step S220: In response to the cooking instruction, the first heating device and the second heating device are turned on for heating, and the operating temperature in the cooking cavity is detected by the temperature detection device.

[0065] In the process of turning on the first heating device and the second heating device for heating, the first heating device and the second heating device may be all turned on, or only part of the heating devices may be turned on, which is not limited in this embodiment. The temperature detection device detects the temperature in the cooking cavity in real time. The output power of the first heating device and the second heating device may be reasonably adjusted according to actual needs.

[0066] Step S230: Determine whether the operating temperature is less than a first set temperature.

[0067] If the operating temperature is lower than the first set temperature, step S240 is executed: controlling the first heating device and the second heating device to heat in a first mode.

[0068] Wherein, the first mode includes synchronous heating by the first heating device and the second heating device.

[0069] When the temperature in the cooking cavity is lower than the set temperature, it indicates that the temperature in the cooking cavity has not yet reached the set value of the heating temperature, so a relatively large output power can be maintained for heating, so that the temperature in the cooking cavity is rapidly increased and reaches the set temperature as soon as possible. The first mode may be, for example, that the first heating device and the second heating device heat in a high-power output manner, wherein the high-power output may refer to that the first heating device and the second heating device heat at a power greater than or equal to 2 / 3 of their respective rated output powers.

[0070] In another embodiment, the first mode is that the first heating device and the second heating device heat at full power. The full-power heating means that the first heating device and the second heating device heat at their respective rated output powers. This heating method can not only maximize the heat output and improve the heating rate, but also enable the first heating device and the second heating device to work in a better state, which is beneficial to extend the service life of the first heating device and the second heating device.

[0071] If the operating temperature is greater than or equal to the first set temperature, step S250 is executed: controlling the first heating device and the second heating device to heat in a second mode.

[0072] The second mode is a mode in which the first heating device and the second heating device perform heating alternately.

[0073] When the temperature in the cooking cavity reaches or exceeds the set temperature, it indicates that there is no need to continue heating with a larger output power. It can be heated with a relatively smaller output power to keep the temperature in the cooking cavity at or near the set temperature. This can reduce power consumption and better control the temperature at the first set temperature.

[0074] In one embodiment, the control device can control the first heating device and the second heating device to adjust the output power in real time for heating in an alternating interval heating manner. This embodiment is conducive to controlling the heating time, thereby reducing power consumption, making the air fryer more energy-efficient. At the same time, it can effectively ensure that the temperature at each position in the cooking cavity tends to be consistent, thereby effectively improving the cooking effect of food.

[0075] When the first heating device and the second heating device are heated alternately, the first heating device is controlled to heat for a first time at a second preset power, and the second heating device is controlled to heat for a second time at a third preset power, and the first time and the second time at least partially do not overlap. Therefore, during the heating process, the heat generated by the first heating device and the second heating device can circulate in the cooking cavity, thereby improving the uniformity of the temperature in the cooking cavity.

[0076] It should be noted that if the air fryer further includes other heating devices, such as the third heating device 160 and the fourth heating device 170, the third heating device 160 and the fourth heating device 170 can heat synchronously with the first heating device and the second heating device in the first mode, and the heating method is similar to the heating method of the first heating device and the second heating device transposed. The third heating device 160 and the fourth heating device 170 can stop heating in the second mode, or heat alternately, etc., and can also heat at low power, such as heating at a heating method less than 1 / 3 of the rated power.

[0077] When the heating time reaches the set time, the heating is stopped.

[0078] When the heating time reaches the set time, the heating process is completed and the heating is stopped. It can be understood that stopping heating means that both the first heating device and the second heating device stop heating. After stopping heating, the user can remove the frying bucket and the food in the frying bucket. In some embodiments, a transition period can be set after stopping heating, during which the user cannot take out the frying bucket to prevent the user from being scalded when taking it out due to the high temperature of the frying bucket. The transition period can be, for example, 1 minute or more, and this embodiment does not limit this.

[0079] The control method of the air fryer provided in this embodiment can not only improve the heating efficiency by controlling the first heating device and the second heating device to heat in different modes at different heating stages, but also improve the uniformity of the temperature in the entire cooking cavity by coordinating the different setting positions of the first heating device and the second heating device.

[0080] Specifically, in one possible implementation of the present application, the method further includes:

[0081] Step S270: Obtain the current heating time.

[0082] The air fryer may start timing when responding to a cooking instruction, and the timing duration at the current moment is the heating duration of the air fryer.

[0083] Step S280: If the ratio of the current heating time to the set time is greater than a preset ratio threshold, and the operating temperature is greater than or equal to the first set temperature, control the first heating device and the second heating device to heat in a second mode, wherein the second mode is a mode in which the first heating device and the second heating device perform alternating heating.

[0084] Step S290: If the ratio between the current heating duration and the set duration is greater than a preset ratio threshold, and the operating temperature is greater than or equal to the first set temperature, the first heating device and the second heating device are controlled to heat in a third mode, the first heating temperature amplitude corresponding to the third mode is greater than the second heating temperature amplitude corresponding to the second mode, and the maximum temperature value corresponding to the first heating temperature amplitude is greater than the maximum value of the second heating temperature amplitude; wherein the first heating temperature amplitude is determined according to the maximum temperature and the minimum temperature detected by the temperature detection device during the heating of the first heating device or the second heating device in the second mode; and the second heating temperature amplitude is determined according to the maximum temperature and the minimum temperature detected by the temperature detection device during the heating of the first heating device and the second heating device in the third mode.

[0085] The first heating device and the second heating device can heat synchronously at intervals in the third mode, or can heat alternately, or can both heat at a lower power, as long as the heating temperature amplitude in the third mode is greater than the heating temperature amplitude corresponding to the second mode.

[0086] Among them, the preset ratio threshold value can be 2 / 3, 3 / 4 or 4 / 5, etc. When the ratio between the current heating time and the set time is greater than the preset ratio threshold value, it means that the food in the cooking chamber is usually heated and cooked. At this time, the food may need to have a better color. By controlling the first heating device and the second heating device to heat in a third mode, the third mode includes the first heating device and the second heating device heating at the same time, the first heating temperature amplitude corresponding to the third mode is greater than the second heating temperature amplitude corresponding to the second mode, and the maximum temperature value corresponding to the first heating temperature amplitude is greater than the maximum value of the second heating temperature amplitude. Due to the large temperature amplitude difference, the moisture on the outer surface of the food is easy to evaporate quickly in a short time, so that the food after heating in the third mode has a better color and appearance. The above-mentioned simultaneous heating of the first heating device and the second heating device specifically means that the first heating device and the second heating device can be turned on or off at the same time.

[0087] In one possible implementation, in order to make the heated food have a better color, in an embodiment of the present application, the method also includes: if the ratio between the current heating time and the set time is greater than a preset ratio threshold, obtaining a second set temperature, the second set temperature is greater than the first set temperature; controlling the first heating device and the second heating device to heat in a fourth mode until the second set temperature is reached, the fourth mode including simultaneous heating of the first heating device and the second heating device.

[0088] The fourth set temperature mentioned above can be the maximum value of the first heating temperature range mentioned above. By adopting the method of making the first heating device and the second heating device heat synchronously, the temperature value in the cooking cavity can be quickly raised to the second set temperature when the food is about to be cooked, and after the temperature is raised to the second set temperature, the first heating device and the second heating device can be controlled to stop heating, or heat at a lower temperature, so that the temperature in the cooking cavity gradually decreases, so that the temperature change in the cooking cavity is larger in the later stage of heating, thereby achieving a better heating effect.

[0089] In one embodiment, the first heating device and the second heating device are arranged at the bottom of the cooking cavity, and the air fryer also includes a third heating device arranged at the top of the cooking cavity and a fourth heating device arranged on the side wall of the cooking cavity. The method also includes: if the operating temperature is lower than the first set temperature, controlling the third heating device and / or the fourth heating device to heat at a fourth preset power.

[0090] Among them, the fourth preset power of the third heating device and / or the fourth heating device can be the rated power of the third heating device and / or the fourth heating device, respectively, or it can be a power greater than or equal to 2 / 3 of the rated power of the third heating device and / or the fourth heating device, and can be set according to actual needs.

[0091] Considering that the temperature at different positions in the cooking cavity may be different, in order to improve the accuracy of the obtained working temperature, there may be multiple temperature detection devices, which are respectively set at different positions in the cooking cavity to detect the temperature at different positions in the cooking cavity, so as to determine the working temperature of the cooking cavity according to the temperature detected by at least one of the multiple temperature detection devices. In addition, when the temperature detection devices are placed at different positions in the cooking cavity, due to the different setting methods and setting positions of the temperature detection devices, the temperature values ​​detected by them may be different from the actual temperature values ​​to a certain extent. In order to improve the accuracy of the obtained working temperature, the working temperature can also be determined according to the detected temperature and the adjusted temperature.

[0092] In one possible implementation of the present application, the temperature detection device includes a first temperature detection device for detecting the temperature near the first heating device and the second heating device, and a second temperature detection device for detecting the temperature near the third heating device 160; the temperature detected by the first temperature detection device is a first measured temperature, and the first real-time temperature is calculated by the first measured temperature and the first adjusted temperature; the temperature detected by the second temperature detection device is a second measured temperature, and the second real-time temperature is calculated by the second measured temperature and the second adjusted temperature; the operating temperature is the first real-time temperature, or the second real-time temperature, or the average of the two.

[0093] The above-mentioned adjustment temperature is used to characterize the difference between the temperature of the detection point in the cooking cavity and the temperature at the target position in the cooking cavity. The adjustment temperatures corresponding to different detection points may be different.

[0094] By determining the working temperature in the cooking cavity based on the measured temperature detected by at least one temperature detection device and the adjusted temperature corresponding to the at least one temperature detection device, the accuracy of the obtained working temperature can be effectively improved.

[0095] In the cooking control method of the present application, different heating times correspond to different heating stages of food in the cooking cavity. The required temperatures of food in different heating stages are different. For example, by obtaining the current working time and temperature of the air fryer, the current working stage of the air fryer is determined according to the current working time, the set time and the first set temperature, and the working modes of each heating device (the first heating device and the second heating device) in the working stage are determined; the current working stage may include any one of the heating temperature rising stage, the heating maturity stage and the heating coloring stage, wherein the heating temperature rising stage refers to a heating stage when the ratio between the current heating time and the set time is less than a preset ratio threshold and the working temperature in the cooking cavity is less than the first set temperature, the heating maturity stage refers to a heating stage when the ratio between the current heating time and the set time is less than the preset ratio threshold and the working temperature in the cooking cavity is not less than the first set temperature, and the heating coloring stage refers to a heating stage when the ratio between the current heating time and the set time is greater than the preset ratio threshold and the working temperature in the cooking cavity is not less than the first set temperature. Among them, different types of cooking stages corresponding to different foods may be different, and the working modes corresponding to the first heating device and the second heating device in different working stages may be different. For example, in the heating and temperature rising stage, the temperature in the cooking cavity needs to be heated up quickly. At this time, the first heating device and the second heating device can be heated synchronously with a higher power. In the heating and maturing stage, it is necessary to ensure that the temperature in the cooking cavity is maintained within a suitable temperature range. At this time, the first heating device and the second heating device can be heated at a lower power, or heated alternately at intervals to maintain a relatively constant temperature. In the heating and coloring stage, a large temperature difference in the cooking cavity is required, or a higher temperature is required. At this time, the first heating device and the second heating device can be heated synchronously so that the temperature range in the cooking cavity changes greatly, or the first heating device and the second heating device can be heated with a larger power. It should be understood that at this time, the average value of the sum of the powers of the first heating device and the second device in the coloring stage should be less than the heating and temperature rising stage and greater than the heating and maturing stage.

[0096] For example, taking roasted chicken wings as an example, if the preset cooking time of roasted chicken wings is 20 minutes, then according to the preset cooking time and cooking recipe, it can be determined that the ratio between the current time and the preset cooking time is within 3 / 4, and the heating stage when the temperature in the cooking cavity is less than ℃ is the heating and heating stage, and the ratio between the current time and the preset cooking time is within 3 / 4, and the heating stage when the temperature in the cooking cavity is not less than ℃ is the heating and coloring stage. If the current cooking time corresponds to the heating and heating stage, the first heating device, the second heating device, and the third heating device can be controlled to all be turned on to achieve rapid heating to improve the efficiency of roasting.

[0097] During the heating stage, when the temperature detected by the thermocouple device reaches 180°C, the first heating device and the second heating device are controlled to heat alternately and the third heating device 160 and the fourth heating device 170 are controlled to stop heating, so that the temperature in the cooking cavity is maintained between 18°C ​​and 200°C during the heating stage. During the alternating heating process between the first heating device and the second heating device, a temperature difference will be generated between the outside and the inside of the container, and hot air will be formed in the cooking cavity and circulate through the gap between the container and the cooking cavity to achieve a more uniform heating effect on the food.

[0098] During the heating and coloring stage, the first heating device and the second heating device can be controlled to heat at intervals synchronously. For example, when the detection temperature detected by the thermocouple device reaches 210°C, the first heating device and the second heating device can be controlled to stop heating. When the temperature detected by the thermocouple detection device drops to 180°C, the first heating device and the second heating device can be controlled to start heating so as to continue the above-mentioned synchronous interval heating during the heating and coloring stage. When the temperature change amplitude during the synchronous interval is large, the purpose of quickly and evenly coloring the food (chicken wings) can be achieved.

[0099] It should also be noted that when the air fryer also includes a third heating device 160 and a fourth heating device 170, the third heating device 160 and the fourth heating device can stop heating during the coloring stage, or can heat synchronously with the first heating device and the second heating device during the heating and coloring stage.
