[0016] 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.

[0017] Please refer to Figure 1 and Figure 2 The air fryer 100 includes a cooking cavity 110 and a first heating device 130, a second heating device 140, a third heating device 150, a first temperature detection device 160, a second temperature detection device 170 and a third temperature detection device 180 arranged in the cooking cavity 110, the first heating device 130 is arranged on a first side of the cooking cavity 110, the second heating device 140 is arranged on a second side of the cooking cavity 110, the third heating device 150 is arranged on a third side of the cooking cavity 110, the first temperature detection device 160 is used to detect the temperature near the first heating device 130, the second temperature detection device 170 is used to detect the temperature near the second heating device 140, and the third temperature detection device 180 is used to detect the temperature near the third heating device 150.

[0018] Conventional air fryers 100 generally adopt a single heat source heating solution, that 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 130, the second heating device 140 and the third heating device 150 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.

[0019] In order to further make the temperatures at different positions in the cooking cavity 110 tend to be consistent, in an embodiment of the present application, the first heating device 130 and the first temperature detection device 160 are respectively arranged at the bottom of the cooking cavity 110, the second heating device 140 and the second temperature detection device 170 are respectively arranged at the top of the cooking cavity 110, the third heating device 150 and the third temperature detection device 180 are respectively arranged on the side walls of the cooking cavity 110, and the third heating device 150 is located between the first heating device 130 and the second heating device 140.

[0020] The heating elements used in the above-mentioned heating devices 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 130, the second heating device 140, and the third heating device 150 are infrared heating tubes.

[0021] The first temperature detection device 160, the second temperature detection device 170 and the third temperature detection device 180 can be any device capable of performing temperature detection, such as a temperature sensor, a thermocouple, etc., and can be configured according to actual needs. The first temperature detection device 160, the second temperature detection device 170 and the third temperature detection device 180 can be of the same type.

[0022] 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.

[0023] In some embodiments, the working states of the first heating device 130, the second heating device 140 and the third heating device 150 can be controlled by the control device 190, that is, the control device 190 can receive cooking instructions sent by the control panel to control the heating modes of the first heating device 130, the second heating device 140 and the third heating device 150. The above-mentioned control device 190 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 100 through the above-mentioned communication module, so as to use the user terminal to send cooking instructions to the control device 190, so that the control device 190 controls the heating modes of the first heating device 130, the second heating device 140 and the third heating device 150 based on the cooking instructions.

[0024] In order to further improve the cooking effect of the air fryer 100, the air fryer 100 may further include a fan, which is used to provide a circulating airflow to the cooking cavity 110; the control device 190 may control the operation of the fan during the heating process of the first heating device 130, the second heating device 140 and the third heating device 150. Exemplarily, the fan may be arranged at the top of the cooking cavity 110. Since the hot air moves upward when heated, by arranging the fan at the top, the power of the fan may 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 uniform.

[0025] 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.

[0026] In which, when the air fryer 100 includes a hot air blower, the control device 190 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 and rotation time of the hot air blower.

[0027] It should be understood that the above-mentioned air fryer 100 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.

[0028] The control device 190 may include a control panel and a control circuit. The control panel may include a controller and a plurality of functional controls connected to the controller, such as a start / stop control, a time adjustment control, a temperature adjustment control, and a plurality of food cooking type controls. The control device may also include a communication module, which may be a Bluetooth module, a wifi module, etc. The user terminal may communicate with the air fryer 100 through the communication module, so as to control the working state of each electrical component in the air fryer 100 using the user terminal. Accordingly, the control device 190 may receive a cooking instruction sent by the user through the control panel to control the heating mode of the first heating device 130, the second heating device 140, and the third heating device 150. The user may also communicate with the air fryer through the communication module of the terminal, so as to send a cooking instruction to the control device 190 using the terminal, so as to enable the control device 190 to control the heating mode of the first heating device 130, the second heating device 140, and the third heating device 150 based on the cooking instruction.

[0029] In order to enable the control device 190 to obtain the temperature detected by each temperature detection component, in one possible implementation mode of the present application, the control device 190 includes a controller and a temperature detection circuit. Specifically, there may be multiple temperature detection circuits, each of which is connected to a temperature detection device, wherein the circuit structure of each temperature detection circuit may be the same, that is, may include the same components.

[0030] For example, Figure 3 As shown, the temperature detection circuit may include electrical components such as capacitors and resistors, and the temperature detection device is arranged on a connection interface with the corresponding temperature detection circuit so that the controller can obtain the temperature detected by the corresponding temperature detection component through the temperature detection circuit.

[0031] See also Figure 4 As shown, the embodiment of the present application further provides a cooking control method, which can be applied to the above-mentioned air fryer 100, and the method includes:

[0032] Step S210: receiving a cooking instruction, wherein the cooking instruction includes a set temperature and a set time.

[0033] 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 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, 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.

[0034] 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.

[0035] 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.

[0036] 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.

[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 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.

[0038] 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.

[0039] Step S220: In response to the cooking instruction, turn on the first heating device, the second heating device and the third heating device, and obtain the first temperature collected by the first temperature detection device, the second temperature collected by the second temperature detection device and the third temperature collected by the third temperature detection device.

[0040] In the process of turning on the first heating device, the second heating device and the third heating device for heating, all of the first heating device and the second heating device may be turned on, or only some of the heating devices may be turned on, which is not limited in this embodiment. The first temperature detection device, the second temperature detection device and the third temperature detection device may detect the temperature in the cooking cavity in real time. The output power of the first heating device, the second heating device and the third heating device may be reasonably adjusted according to actual needs.

[0041] Step S230: determining whether the first temperature, the second temperature, and the third temperature are all lower than a reference temperature.

[0042] If the first temperature, the second temperature and the third temperature are all lower than the reference temperature, step S240 is performed: controlling the first heating device, the second heating device and the third heating device to perform heating in a first mode.

[0043] Wherein, the first mode includes synchronous heating by the first heating device, the second heating device and the third heating device.

[0044] Specifically, the reference temperature can be determined based on a preset temperature adjustment value and a set temperature. The preset temperature adjustment value can be predetermined based on the actual temperature at different locations and the temperature detected by each temperature detection device (such as a first temperature detection device, a second temperature detection device, and a third temperature detection device), and the preset temperature adjustment values ​​corresponding to different temperature detection devices in different temperature detection intervals can be the same or different. When different temperature detection devices have different corresponding preset temperature adjustment values ​​in different detection temperature intervals, the reference temperatures corresponding to different temperature detection devices are different, that is, if the first temperature, the second temperature, and the third temperature are not greater than their respective corresponding reference temperatures, the first heating device, the second heating device, and the third heating device are controlled to heat in the first mode.

[0045] If the first temperature, the second temperature and the third temperature are not greater than the reference temperature, it indicates that the temperature in the current 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 quickly increased and reaches the set temperature as soon as possible. The first mode may be, for example, that the first heating device, the second heating device and the third heating device heat in a high-power output manner, wherein the high-power output may refer to that the first heating device, the second heating device and the third heating device heat at a power greater than or equal to 2 / 3 of their respective rated output powers.

[0046] In another embodiment, the first mode is that the first heating device, the second heating device and the third heating device are heated in a full-power mode. The full-power heating mode means that the first heating device, the second heating device and the third heating device are heated 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, the second heating device and the third heating device to work in a better state, which is conducive to extending the service life of the first heating device, the second heating device and the third heating device.

[0047] Execute step S250: if the first temperature, the second temperature or the third temperature is greater than the reference temperature and the first temperature, the second temperature and the third temperature are all less than the preset temperature threshold, if the operating temperature is greater than or equal to the first set temperature, control the first heating device, the second heating device and the third heating device to heat in the second mode.

[0048] The total heating power of the first heating device, the second heating device and the third heating device when heating in the second mode is less than the total heating power when heating in the first mode, and the preset temperature threshold is greater than the set temperature and the reference temperature.

[0049] The second mode is a mode in which the first heating device and the second heating device perform heating alternately.

[0050] When the temperature in the cooking cavity reaches or exceeds the reference 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.

[0051] 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.

[0052] 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.

[0053] When the heating time reaches the set time, the heating is stopped.

[0054] 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.

[0055] The control method of the air fryer provided in this embodiment can not only improve the heating efficiency by controlling the first heating device, the second heating device and the third heating device to heat in different modes at different heating stages, but also improve the temperature uniformity in the entire cooking cavity by coordinating the different setting positions of the first heating device, the second heating device and the third heating device.

[0056] Specifically, in one possible implementation manner of the present application, the reference temperature includes a first reference temperature, a second reference temperature and a third reference temperature. During the heating process of the first heating device, the second heating device and the third heating device in the first mode, if the first temperature, the second temperature or the third temperature is greater than the reference temperature and the first temperature, the second temperature and the third temperature are all less than a preset temperature threshold, the above step S240 includes: during the heating process of the first heating device, the second heating device and the third heating device in the first mode, according to the preset temperature and the first preset detection deviation, obtaining the first reference temperature; according to the preset temperature and the second preset detection deviation, obtaining the second reference temperature; according to the preset temperature and the third preset detection deviation, obtaining to the third reference temperature; the first preset detection deviation is used to characterize the difference between the temperature at the target position of the cooking cavity in the first heating mode and the temperature detected by the first temperature detection device, the second preset detection deviation is used to characterize the difference between the temperature at the target position in the first heating mode and the temperature detected by the second temperature sensor, and the third preset detection deviation is used to characterize the difference between the temperature at the target position in the first heating mode and the temperature detected by the third temperature detection device; if the first temperature is greater than the first reference temperature, the second temperature is greater than the second reference temperature, the third temperature is greater than the third reference temperature, and the first temperature, the second temperature and the third temperature are all less than the preset temperature threshold, the first heating device, the second heating device and the third heating device are controlled to heat in the second mode.

[0057] There may be no correlation between the first preset deviation value, the second preset deviation value and the third preset deviation value. For example, the first preset deviation value may be 8°C, 10°C, 12°C or 15°C, etc., the second preset deviation value may also be 8°C, 10°C, 12°C or 15°C, etc., and the third preset deviation value may be 8°C, 10°C, 12°C or 15°C, etc. In one possible implementation of the present application, considering that when the first heating device, the second heating device and the third heating device are heating in the first mode, in order to increase the temperature in the cooking cavity faster, continuous heating may be used for heating (e.g., each heating device heats at rated power), and the temperature may continue to rise for a period of time after the heating stops. Therefore, in one possible implementation of the present application, the value of the first preset deviation value may be 10°C, the value of the second preset deviation value may be 10°C, and the value of the third preset deviation value may be 10°C.

[0058] In the second mode, the first heating device, the second heating device and the third heating device can work simultaneously or partially. It should be understood that when the first heating device, the second heating device and the third heating device work simultaneously, they can be started alternately at intervals to heat, or they can be heated at a lower power (lower than the power in the first heating mode). As long as the heating power in the second mode can be guaranteed to be lower than the heating power corresponding to the first mode, it will be fine.

[0059] In one embodiment, if in the second mode, the first heating device, the second heating device, and the third heating device are heated by periodic interval heating, the period duration of the heating cycle corresponding to each heating device may be the same or different. For example, the first heating device may perform periodic heating of (x1, y1), where x1 is the heating duration of the first heating device in one heating cycle, which may be set to more than 5 seconds, and y1 is the duration of the heating cycle of the first heating device, which may be more than 10 seconds. The second heating device performs periodic heating of (x2, y2), where x2 is the heating duration of the second heating device in one heating cycle, which may be set to more than 5 seconds, and y2 is the duration of one heating cycle of the second heating device, which may be set to more than 10 seconds. The third heating device performs periodic heating of (x3, y3), where x3 is the heating duration of the third heating device in one heating cycle, which may be set to more than 5 seconds, and y3 is the duration of one heating cycle of the third heating device, which may be set to more than 10 seconds. It should be understood that the duration of the corresponding heating cycles of different heating devices may be different, and the heating duration in one heating cycle may also be different.

[0060] In one possible implementation, during the heating process of the first heating device, the second heating device and the third heating device in the second mode, if the first temperature, the second temperature and the third temperature are all greater than the reference temperature and less than the preset temperature threshold, the first heating device, the second heating device and the third heating device are controlled to heat in the third mode; the total heating power of the first heating device, the second heating device and the third heating device when heating in the third mode is less than the total heating power when heating in the second mode.

[0061] In the third mode, the first heating device, the second heating device and the third heating device can work simultaneously or partially. It should be understood that in the third mode, when the first heating device, the second heating device and the third heating device work simultaneously, they can be started alternately at intervals to perform heating, or they can be heated at a lower power (lower than the power in the second heating mode). As long as the heating power in the third mode can be guaranteed to be lower than the heating power corresponding to the second mode, it will be fine.

[0062] In one embodiment, controlling the first heating device, the second heating device and the third heating device to heat in the second mode includes: controlling the first heating device and the second heating device to heat periodically, and / or controlling the third heating device to heat at a second preset power; controlling the first heating device, the second heating device and the third heating device to heat in the third mode includes: controlling the first heating device and the second heating device to stop heating, and / or controlling the third heating device to adjust the output power for heating in real time.

[0063] In one possible implementation of the present application, the reference temperature includes a fourth reference temperature, a fifth reference temperature and a sixth reference temperature. When the first heating device, the second heating device and the third heating device are heated in the second mode, if the first temperature, the second temperature and the third temperature are all greater than the reference temperature and less than the preset temperature threshold, the first heating device, the second heating device and the third heating device are controlled to heat in the third mode, including: when the first heating device, the second heating device and the third heating device are heated in the second mode, according to the preset temperature and the fourth preset detection deviation, obtaining the fourth reference temperature; according to the preset temperature and the fifth preset detection deviation, obtaining the fifth reference temperature; according to the preset temperature and the sixth preset detection deviation, obtaining the sixth reference temperature; reference temperature; the fourth preset detection deviation is used to characterize the difference between the temperature at the target position of the cooking cavity in the second heating mode and the temperature detected by the first temperature detection device, the fifth preset detection deviation is used to characterize the difference between the temperature at the target position in the second heating mode and the temperature detected by the second temperature detection device, and the sixth preset detection deviation is used to characterize the difference between the temperature at the target position in the second heating mode and the temperature detected by the third temperature detection device; if the first temperature is greater than the fourth reference temperature, the second temperature is greater than the fifth reference temperature or the third temperature is greater than the sixth reference temperature, and the first temperature, the second temperature and the third temperature are all less than the preset temperature threshold, the first heating device, the second heating device and the third heating device are controlled to heat in the third mode.

[0064] Among them, in order to avoid the problem that the food is easily burnt due to too high temperature and the food cannot be cooked due to too low temperature, the specific values ​​of the fourth preset temperature deviation value, the fifth preset temperature deviation value and the sixth preset temperature deviation value should be smaller than the first preset temperature deviation value, the second preset temperature deviation value and the third preset temperature deviation value. For example, the value of the fourth preset temperature deviation value can be 1°C, 2°C or 5°C, the value of the fifth preset temperature deviation value can be 1°C, 2°C or 5°C, and the value of the sixth preset temperature deviation value can be 1°C, 2°C or 5°C. For example, in a specific embodiment, the value of the fourth preset temperature deviation value can be 1°C, the value of the fifth preset temperature deviation value can be 1°C, and the value of the sixth preset temperature deviation value can be 5°C.

[0065] In one possible implementation of the present application, during the heating process of the first heating device, the second heating device and the third heating device in the third mode, if the first temperature, the second temperature and the third temperature are all lower than the reference temperature, the first heating device, the second heating device and the third heating device are controlled to heat in the second mode.

[0066] It should be noted that, during the heating process of the first heating device, the second heating device and the third heating device in the third mode, if the first temperature, the second temperature and the third temperature are all lower than the reference temperature, it means that the temperature in the cooking cavity is too low, and the temperature in the cooking cavity needs to be appropriately increased to ensure that the temperature in the cooking cavity is neither too high nor too low, thereby ensuring that the food in the cooking cavity will not be burnt due to excessively high temperature during heating, nor will the food maturation efficiency be low due to too low temperature or the cooking effect be poor due to too low temperature.

[0067] In one possible implementation of the present application, when the first heating device, the second heating device and the third heating device are heated in the third mode, if the first temperature, the second temperature and the third temperature are greater than the reference temperature, the first heating device, the second heating device and the third heating device are controlled to heat in the third mode, including: when the first heating device, the second heating device and the third heating device are heated in the third mode, a seventh reference temperature is obtained according to the preset temperature and the seventh preset detection deviation; an eighth reference temperature is obtained according to the preset temperature and the eighth preset detection deviation; a ninth reference temperature is obtained according to the preset temperature and the ninth preset detection deviation; the seventh preset detection deviation is used to characterize the difference between the temperature at the target position of the cooking cavity in the third heating mode and the temperature detected by the first temperature detection device, the eighth preset detection deviation is used to characterize the difference between the temperature at the target position in the third heating mode and the temperature detected by the second temperature detection device, and the ninth preset detection deviation is used to characterize the difference between the temperature at the target position in the second heating mode and the temperature detected by the third temperature detection device; if the first temperature is less than the seventh reference temperature, the second temperature is less than the eighth reference temperature and the third temperature is less than the ninth reference temperature, the first heating device, the second heating device and the third heating device are controlled to heat in the second mode.

[0068] In order to speed up the cooking efficiency of food, avoid the problem that food is easily burnt due to too high temperature and food cannot be cooked due to too low temperature, and improve the convenience of controlling the air fryer 100, the seventh preset temperature deviation value may be 2°C, 3°C, 5°C or 7°C, the fifth preset temperature deviation value may be 2°C, 3°C, 5°C or 7°C, and the sixth preset temperature deviation value may be 2°C, 3°C, 5°C, 7°C or 8°C. For example, in a specific embodiment, the seventh preset temperature deviation value may be 3°C, the eighth preset temperature deviation value may be 3°C, and the ninth preset temperature deviation value may be 7°C.

[0069] In one embodiment, during the heating process, if the first temperature, the second temperature or the third temperature is greater than or equal to the preset temperature threshold, the first heating device, the second heating device and the third heating device are controlled to heat in a fourth mode, and the total heating power of the first heating device, the second heating device and the third heating device when heating in the fourth mode is less than the total heating power when heating in the second heating mode.

[0070] It should be noted that the preset temperature threshold is a safety reference temperature in the air fryer. If the first temperature, the second temperature or the third temperature is greater than or equal to the preset temperature threshold, it means that if the heating devices in the air fryer continue to use the air fryer at a higher power, it may cause the air fryer to malfunction or be damaged. Therefore, it is necessary to control the first heating device, the second heating device and the third heating device to heat in a fourth mode, wherein in the fourth mode, each heating device stops heating or continues to be used at 10% of the rated power or 5% of the rated power.

[0071] In one possible implementation, controlling the first heating device, the second heating device, and the third heating device to heat in a fourth mode includes: controlling the first heating device, the second heating device, and the third heating device to stop heating.

[0072] like Figure 5 As shown, the present application exemplarily provides a cooking control method of an air fryer 100, which is applied to Figure 1 The air fryer in the invention has a medium-power lower heating tube (a first heating device arranged at the bottom of the cooking cavity), a high-power upper heating tube (a second heating component arranged at the top of the cooking cavity), a low-power heating belt (a third heating device arranged on the side wall of the cooking cavity), a fan and other electrical components. The lower heating tube (the first heating device), the upper heating tube (the second heating device), and the heating belt (the third heating device) are used for heating. The fan is driven by a motor with fan blades to blow air. It has several gears, which are defined by high gear (above 2500rpm / min), medium gear (1500-2500rpm / min), and low gear (below 1500rpm / min). The bottom heating tube (the first heating device) can heat the bottom in a large range due to its large heat dissipation range. An NTC1 sensor (the first temperature detection device 160) is installed at the bottom of the frying barrel to collect the bottom temperature. An NTC2 sensor (the second temperature detection device 170) is used above the frying barrel to collect the temperature. The side wall of the frying vat is also equipped with an NTC3 sensor (third temperature detection device 190) for temperature collection. The temperature sensing accuracy can be provided based on at least two of NTC, NTC2 and NTC3. The specific cooking control process is as follows:

[0073] The user selects a function, sets the temperature and time, and presses the start button to start cooking, and the air fryer 100 starts working. The corresponding function indicator of the air fryer 100 lights up, and the countdown is displayed. Each NTC sensor detects the temperature of the cooking cavity 110 in real time. Then the control component 180 controls the fan to rotate at a high speed.

[0074] After the air fryer 100 is started, the following working process can be performed:

[0075] Process 1: The air fryer 100 is tested throughout the entire process. If the NTC1 temperature is greater than Temp1 (Temp1 is the NTC ultra-high temperature protection temperature, set to above 200°C), or the NTC2 temperature is greater than Temp2 (Temp2 is the NTC2 ultra-high temperature protection temperature, set to above 200°C), or the NTC2 temperature is greater than Temp3 (Temp3 is the NTC3 ultra-high temperature protection temperature, set to above 200°C), the ultra-high temperature protection process will be entered and all heating loads will stop. When the temperature cools down to below 105°C (the temperatures detected by each NTC are all less than 105°C), the normal cooking process can be carried out. Among them, Temp1, Temp2 and Temp3 all refer to the aforementioned target temperature thresholds.

[0076] Process 2: After the air fryer 100 starts working, it first performs cooking in the first flushing stage. At this time, the lower heating tube (first heating component), the upper heating tube (second heating component), and the heating belt (third heating component) are all heated at full power, and the fan rotates at a medium or high position so that the hot air circulates and the heat flows quickly to every part of the frying bucket. If the NTC1 temperature is greater than (preset temperature-move1), and the NTC2 temperature is greater than (preset temperature-move2) and the NTC3 temperature is greater than (preset temperature-move3), it is considered to be satisfied, exceeding the first flushing temperature, and entering the next stage. Move1 is the NTC first flushing offset temperature, that is, the first preset temperature deviation value in the aforementioned embodiment, generally set to more than 10°C. Move2 is the NTC2 first flushing offset temperature, that is, the second preset temperature deviation value in the aforementioned embodiment, generally set to more than 10°C. Move3 is the NTC3 first flushing offset temperature, that is, the third preset temperature deviation value in the aforementioned embodiment, generally set to more than 10°C.

[0077] Process 3: The upper heating tube performs heating at intervals (x1, y1), x1 is the heating start time, generally set to more than 5 seconds, y1 is the heating cycle, generally set to more than 10 seconds. The heating belt performs full power heating. The lower heating tube performs heating at intervals (x2, y2), x2 is the heating start time, generally set to more than 5 seconds, y2 is the heating cycle, generally set to more than 10 seconds. The fan rotates at medium or high gear.

[0078] Process 4: If the air fryer 100NTC temperature is greater than (preset temperature-move4), and the NTC2 temperature is greater than (preset temperature-move5) and the NTC3 temperature is greater than (preset temperature-move6), the upper heating tube stops heating, the heating belt adjusts the power for heating (low power maintenance adjustment according to the actual menu performance to maintain temperature balance), the lower heating tube stops heating, and the fan adjusts the gear (high, medium and low gear switching adjustment according to the selected menu performance). Otherwise, return to process 3 for cooking.

[0079] Move4 is the offset temperature value of the NTC preset temperature, that is, the fourth preset temperature deviation value in the aforementioned embodiment, which is generally set to be above 1C. Move5 is the offset temperature value of the NTC2 preset temperature, that is, the fifth preset temperature deviation value in the aforementioned embodiment, which is generally set to be above 5C. Move6 is the offset temperature value of the NTC3 preset temperature, that is, the sixth preset temperature deviation value in the aforementioned embodiment, which is generally set to be above 1C.

[0080] Process 5: If NTC1 temperature < (preset temperature - move7), NTC2 temperature < (preset temperature - move8) and NTC3 temperature < (preset temperature - move9), then return to process 4 for cooking. Otherwise, enter process 3 for cooking.

[0081] Move7 is the offset value for NTC working temperature recovery, that is, the seventh preset temperature deviation value in the aforementioned embodiment, generally set to be above 2°C. Move8 is the offset value for NTC2 working temperature recovery, that is, the eighth preset temperature deviation value in the aforementioned embodiment, generally set to be above 7°C. Move9 is the offset value for NTC3 working temperature recovery, that is, the ninth preset temperature deviation value in the aforementioned embodiment, generally set to be above 2°C.

[0082] The countdown ends when the set time (usually set to a cooking time of more than 1 minute) reaches 0 and the machine returns to standby mode.

[0083] like Figure 6 As shown, the embodiment of the present application also provides a cooking control device 300 for an air fryer, and the device 300 is applied to the above-mentioned air fryer, and the device 300 includes: an instruction receiving module 310 and an execution module 320, the instruction receiving module is used to receive a cooking instruction, and the cooking instruction includes a set temperature and a set duration. The execution module is used to respond to the cooking instruction, turn on the first heating device, the second heating device, and the third heating device, and obtain the first temperature collected by the first temperature detection device, the second temperature collected by the second temperature detection device, and the third temperature collected by the third temperature detection device; if the first temperature, the second temperature, and the third temperature are not greater than the reference temperature, control the first heating device, the second heating device, and the third heating device to heat in a first mode, wherein the reference temperature is determined based on the set temperature, and the first mode includes the first heating device, the second heating device, and the third heating device synchronously heating; when the heating duration reaches the set duration, stop heating.
