[0002] With the pursuit of healthy diet by users, air fryers have gradually come into people's view. An air fryer evaporates the moisture on the surface of food through high-speed circulating hot air, enabling the food to achieve the cooking effect of a frying pan without oil, thereby reducing the intake of grease and making the food healthier. In addition, an air fryer does not require the use of oil and water, is simple and convenient to operate, and has a fast cooking speed.

[0058] In order to enable those skilled in the art of the present technology 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 accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or indirectly connected through an intermediate medium, or the communication inside two components, or just surface contact, or surface contact connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0060] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as specific or special structures. The descriptions of terms such as "some embodiments", "other embodiments", etc. mean that the specific features, structures, materials, or characteristics described in connection with the embodiment or example are included in at least one embodiment or example of this application. In this application, the schematic expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. In addition, without contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this application and the features of different embodiments or examples.

[0061] An embodiment of this application provides a cooking appliance 500. Please refer to Figure 1 , the cooking appliance 500 can be an air fryer, etc. The air fryer can evaporate the moisture on the surface of foods such as vegetables through high-speed circulating hot air flow, so that the food can achieve the cooking effect of a fryer without oil.

[0062] Please refer to Figure 2 together, the cooking appliance 500 can include a pot body 510, a first heating device 520, a second heating device 530, a blower 540, and a temperature detection device 550. The pot body 510 can be arranged inside a housing 580 of the cooking appliance 500. The first heating device 520 is located below the pot body 510, and the second heating device 530 is located above the pot body 510. The blower 540 can be arranged on the side of the second heating device 530 away from the pot body 510, and the temperature detection device 550 can be arranged on the surface of the pot body 510.

[0063] Specifically, please continue to refer to Figure 2 , the housing 580 can include a base 581 and a top cover 582. The housing 580 can be made of a metal material, which has good heat dissipation, reduces the influence of internal heat on the components of the housing 580, and ensures the use safety of the cooking appliance 500. The metal housing has high strength and long service life, ensures the use safety of the components inside the cooking appliance 500, and reduces the influence brought by external vibration or impact.

[0064] A content cavity 583 is formed between the base 581 and the top cover 582. The base 581 and the top cover 582 are detachably connected to facilitate subsequent separate replacement and reduce maintenance costs. In one embodiment, the housing 580 further includes a first opening that communicates with the content cavity 583. The cooking pot 510 is detachably received in the content cavity 583. The first opening is located between the base 581 and the top cover 582, and the cooking pot 510 can be pushed into the content cavity 583 through the first opening.

[0065] The cooking pot 510 can be used to hold the food to be cooked. In this embodiment, the cooking pot 510 can be made of a non-stick coating material. The surface of the non-stick coating cooking pot is coated with an artificial coating, which is very smooth, making the fryer easier to clean and convenient for cooking, and can also reduce unnecessary oil use. The cooking pot 510 can also be made of stainless steel. The stainless steel cooking pot has strong rust prevention ability and good corrosion resistance. The cooking pot 510 made of stainless steel material is also more durable and easy to clean. The cooking pot 510 can also be made of aluminum alloy. The cooking pot 510 made of aluminum alloy material is light in weight and has good heat conduction effect, and can quickly conduct heat, suitable for cooking in a short time. The cooking pot 510 can also be made of carbon steel. The cooking pot 510 made of carbon steel material has high weight resistance, wear resistance and corrosion resistance, and can adapt to more cooking needs and occasions.

[0066] In this embodiment, the cooking pot 510 can further include a frying basket (not shown in the figure). The frying basket can be a kitchenware accessory for baking food inside the cooking appliance 500. The frying basket can be made of food-grade aluminum alloy and other materials, and has different specifications and shapes to adapt to different foods and baking needs. The bottom of the cooking pot 510 has a convex structure. When the frying basket is placed in the cooking cavity, the bottom of the frying basket can abut against the convex structure to lift the frying basket. Then the food to be cooked is placed on the surface of the frying basket facing the blower 540. The frying basket can be used to cook various foods in the cooking appliance 500, so that the surface of the food is impacted by the hot air flow and becomes golden and crispy. Compared with the bottom wall of the cooking pot 510 having a convexity, the frying basket can provide a flat placement plane, and the food to be cooked can be placed on this plane, which is convenient for food placement and avoids food stacking and affecting each other.

[0067] The first heating device 520 can be disposed on the base 581. Further, the first heating device 520 can be directly abutted against the cooking pot 510, and thus the first heating device 520 can directly heat the cooking pot 510. Compared with heat transfer by air flow, the heat conduction efficiency from the first heating device 520 to the cooking pot 510 can be improved, and thus the heating effect of the first heating device 520 can be improved.

[0068] Please continue to refer to Figure 2, the second heating device 530 is disposed on the top cover 582, and the blower 540 is also disposed on the top cover 582. The blower 540 is located on a side of the second heating device 530 away from the pot body 510. The blower 540 is used to form an air flow circulation in the pot body 510. The air flow can pass through the second heating device 530. When the second heating device 530 is powered on, it generates heat. The air flow passing through the second heating device 530 will be heated to form a hot air flow. The hot air flow driven by the blower 540 circulates in the cooking cavity, and the temperature in the cooking cavity rises sharply. The food to be cooked will be heated and cooked by the hot air flow until the food is completely cooked.

[0069] In a more specific embodiment, please refer to Figure 1 and Figure 2 , the blower 540 may include a driving device 541 and a fan blade 542. The driving device 541 is disposed on a side of the top cover 582 away from the pot body 510. The top cover 582 is provided with a reflector 584. The reflector 584 can be used to limit the heating range and guide the air flow. The reflector 584 is provided with a mounting hole 585. The output shaft of the driving device 541 passes through the mounting hole 585. The fan blade 542 can be disposed on the output shaft and rotates coaxially. The fan blade 542 is located between the first heating device 520 and the reflector. The fan blade 542 can be driven to generate an air flow inside the cooking cavity to achieve internal heat circulation.

[0070] In one embodiment, the output shaft of the driving device 541 passes through the mounting hole 585. The diameter of the output shaft can be slightly smaller than the diameter of the mounting hole 585 so that the output shaft can pass through the mounting hole 585 smoothly, ensuring that the output shaft can rotate smoothly in the mounting hole 585 and also preventing heat from escaping through the mounting hole 585 to ensure the energy utilization rate.

[0071] Preferably, the mounting hole 585 is opened on the top cover 582 and can be disposed at the center of the top cover 582. For example, the top cover 582 can be circular, and the axes of the mounting hole 585 and the top cover 582 coincide with each other, so that the distance from the output shaft disposed on the mounting hole 585 to each part of the edge of the top cover 582 is the same. The top cover 582 can be provided with a larger-sized fan blade, thereby increasing the acting area of the blower 540 and generating a larger air flow range.

[0072] In this embodiment, the driving device 541 can adopt a direct current brushless motor. A direct current brushless motor is a direct current motor using electronic commutation and has the following advantages compared with a traditional alternating current motor:

[0073] First, the DC brushless motor has a higher energy efficiency ratio: Since there is no need to adjust the current reversal through a traditional commutator, the DC brushless motor can stop and start the motor in a shorter time and has lower energy consumption, so the energy efficiency ratio is higher. Second, the DC brushless motor has a longer lifespan: Because there is no friction material (such as carbon brushes) inside the motor, the friction loss during the operation of the motor is smaller and the lifespan is longer. Moreover, the DC brushless motor has less noise: Since the friction generated inside the motor is smaller, the noise of the motor is lower. Finally, the DC brushless motor has a wide speed regulation range: The speed regulation range of the DC brushless motor is relatively wide, which can adapt to different load and working condition requirements.

[0074] It can be understood that within the normal power range, the power of the blower 540 determines the rotational speed of the driving device 541. By changing the power of the blower 540, the rotational speed of the blower 540 can be adjusted accordingly. To change the flow rate of the air flow inside the pot body 510, and then change the flow rate of the internal heat circulation, thereby changing the cooking effect of the cooking appliance 500.

[0075] In one embodiment, both the first heating device 520 and the second heating device 530 can be heating tubes. When the heating tubes are powered on, heat is generated, which then promotes heat exchange of the passing air flow to achieve hot air circulation.

[0076] It can be understood that the first heating device 520 and the second heating device 530 can independently select one or more of stainless steel heating tubes, quartz heating tubes, Teflon heating tubes, and titanium heating tubes. In this embodiment, both the first heating device 520 and the second heating device 530 can adopt heating elements made of semiconductor materials with a very large positive temperature coefficient (Positive Temperature Coefficient, PTC). The PTC heating element is a kind of thermosensitive material. Within a certain voltage range, the change in its resistivity is proportional to the temperature. When the temperature rises, the resistance performance gradually increases, causing the PTC resistance value to increase, thereby generating a higher heating effect.

[0077] The temperature detection device 550 can be a thermal resistance sensor, a far-infrared thermometer, a thermocouple sensor, etc. The thermal resistance sensor can be made based on the characteristic that the resistance value changes with temperature, and is convenient and reliable to use and has been widely applied. The far-infrared thermometer is a non-contact temperature measurement device that can perform on-line infrared radiation measurement of the object to be measured. It has the characteristics of strong anti-electromagnetic interference performance, accurate temperature measurement, high resolution, and fast dynamic response. The thermocouple sensor uses two conductors with different compositions connected at both ends to form a loop. When the temperatures at the two nodes are different, an electromotive force will be generated in the loop, which can indicate the temperature measurement when the voltage changes. It can be understood that the selection and design of the temperature detection device 550 can be carried out according to the specific implementation scenario and measurement target, and this embodiment does not limit it.

[0078] The temperature detection device 550 can be used to obtain the temperature of the cooking cavity of the pot body 510. The installation position can be selected and designed according to the specific type of the temperature detection device 550. Exemplarily, when the temperature detection device 550 is a far-infrared thermometer, the temperature detection device 550 can be arranged at an interval from the pot body 510, and the temperature of the pot body 510 can be detected through an infrared radiation signal lamp. The temperature detection device 550 can not only avoid the interference of high heat on its own structure, but also ensure the accuracy of temperature detection. When the temperature detection device 550 is a thermal resistance sensor, the temperature detection device 550 can be arranged adjacent to the pot body 510. For example, the temperature detection device 550 can be attached to the bottom of the pot body 510. The temperature detection device 550 can be in direct contact with the pot body 510, and the internal resistance of the temperature detection device 550 is changed by the temperature to detect the specific temperature of the pot body 510. The temperature of the pot body 510 can be obtained through the temperature detection device 550, so that other devices or the cooking appliance 500 can adjust the heating parameters by using the temperature measurement result of the temperature detection device 550.

[0079] Please refer to Figure 2 Figure, the cooking appliance 500 further includes a control panel (not shown in the figure). The control panel can be electrically connected to the blower 540, the first heating device 520, and the second heating device 530. The control panel can be used to receive control instructions from the user, and the control panel can control the blower 540, the first heating device 520, and the second heating device 530 according to the control instructions. Exemplarily, the control panel can control the power-on state, rotation speed, etc. of the blower 540, and the control panel can control the power-on state, output power, etc. of the first heating device 520 and the second heating device 530. So that the cooking appliance 500 can have more baking modes and baking degree selections, and improve the baking effect of the cooking appliance 500.

[0080] In one embodiment, the control panel may further include a display screen, a timer, etc. The display screen can be used to display the working state, internal temperature, working duration of each component, etc. of the cooking appliance 500. The display screen can be a touch display screen, and the user can operate the display screen to change the working state, etc. of the cooking appliance 500. The timer is used to record the working duration of each component of the cooking appliance 500.

[0081] This embodiment also provides a cooking method, which can be applied to the foregoing cooking appliance. Please refer to Figure 3 Figure, the cooking method includes the following steps S110-S120:

[0082] Step S110: In response to a cooking instruction issued by the user, turn on the first heating device, the second heating device, and the blower; the cooking instruction includes cooking parameters, and the cooking parameters include the first heating temperature of the first heating device, the second heating temperature of the second heating device, and the set duration, and the first heating temperature is greater than the second heating temperature.

[0083] The cooking appliance can pre-store several preset programs, and each preset program can be used to process specific ingredients respectively, such as the preset programs for processing vegetables like potatoes and green vegetables. Each preset program includes corresponding parameters such as heating duration and heating temperature. When the user selects a preset program as a control instruction, by retrieving the parameters of the preset program, the corresponding cooking parameters can be determined.

[0084] In response to the control instruction sent by the user, control each component of the cooking appliance to work according to the control instruction. The first heating device and the second heating device can be controlled to start heating. Specifically, the cooking appliance can control the first heating device to be powered on and start timing simultaneously to form a first working duration. The cooking appliance can also control the second heating device to be powered on and start timing simultaneously to form a second working duration. Moreover, by comparing the first working duration and the second working duration with the set duration, the working states of the first heating device and the second heating device can be judged and controlled. The cooking appliance can control the blower to operate according to the operating parameters. The operating parameters can include parameters such as rotation direction, rotation speed, and operating duration. Exemplarily, the blower can be used in cooperation with the second heating device, and the cooking appliance can determine the operating parameter values of the blower at different time periods according to the working state of the second heating device. When the second heating device starts to work, the blower can start operating according to the operating parameters until the second heating device stops heating.

[0085] In another embodiment, the cooking appliance can also include a preheating program. Within a period of time after the user selects to complete the preset program, the first heating device, the second heating device, and the blower can be preheated according to the preheating program, or the cooking appliance can start preheating when the user installs the pot body in place and turns on the power. The preheating program can judge whether the cooking appliance can work normally.

[0086] Among them, the cooking parameters include the first heating temperature of the first heating device, the second heating temperature of the second heating device, and the set duration. The first heating temperature is the set temperature of the first heating device, and the first heating device can heat according to the first heating temperature. The second heating temperature is the set temperature of the second heating device, and the second heating device can heat according to the second heating temperature.

[0087] When cooking vegetables, the first heating temperature is higher than the second heating temperature, which reduces the temperature of the hot air flow in the cooking cavity, thereby reducing the cooking effect of the hot air flow on the vegetables, improving the cooking effect of the first heating device, and ensuring that the vegetables are cooked thoroughly. For example, when the food to be cooked is water spinach, according to factors such as the heat transfer efficiency and cooking effect of the first heating device and the second heating device, the first heating temperature can be 130°C - 150°C, preferably 140°C. The second heating temperature can be 110°C - 130°C, preferably 120°C, and the temperature difference between the two is in the range of 0°C - 40°C, preferably 20°C. Compared with the first heating temperature of the first heating device, the second heating temperature of the second heating device is lower, which reduces the temperature of the hot air flow in the cooking cavity and reduces the cooking effect of the hot air flow on the vegetables, thus preventing the moisture of the vegetables from being quickly dried. Since the heat loss of the direct heat conduction of the first heating device is less than that of the second heating device through air heat circulation, the heat conduction effect is better. The first heating temperature of the first heating device is higher, and the cooking effect of the first heating device is improved, ensuring that the vegetables are cooked thoroughly.

[0088] The set duration can be the operating duration of the cooking appliance. By adjusting the power-on and power-off times of the first heating device, the second heating device, and the blower, the operating duration of the cooking appliance can be changed. Or the set duration can be the heating duration of the first heating device and / or the second heating device. Among them, the specific parameters such as the set duration, the first heating temperature, and the second heating temperature in the preset program of the cooking appliance are not unique and need to be set differently according to the configuration parameters of each cooking appliance. This embodiment does not limit them.

[0089] It can be understood that the cooking parameters also include the specific operating periods and operating parameters of the first heating device, the second heating device, and the blower during the operation of the cooking appliance. This embodiment does not limit them, and they are adjusted according to specific cooking requirements.

[0090] Step S120: When the heating duration is greater than the set duration, turn off the first heating device and the second heating device.

[0091] The heating duration is calculated from the start working time of the first heating device and / or the second heating device, and the heating duration and the set duration can be compared. When the heating duration is greater than the set duration, the power supply to the first heating device and the second heating device is stopped, that is, the heating process is completed, to prevent the device from further heating, ensure the cooking effect of the food to be cooked, and prevent overcooking.

[0092] In another embodiment, when the heating duration is greater than the set duration, the cooking appliance can report to the user the end of the work and other situations through sound or visual prompts to remind the user to take corresponding measures.

[0093] Based on the above cooking method, the embodiments of the present application further provide another cooking method. Refer to Figure 4 , the cooking method provided in this embodiment may further include the following steps S210 - S230. It should be understood that in the cooking method of this embodiment, there are the same or corresponding implementation steps as those in the above embodiment. For the specific elaboration of these same or corresponding implementation steps, reference may be made to the content provided in the above embodiment, and this embodiment will not be elaborated herein.

[0094] Step S210: In response to a cooking instruction issued by the user, turn on the first heating device, the second heating device, and the blower; the cooking instruction includes cooking parameters, and the cooking parameters include the first heating temperature of the first heating device, the second heating temperature of the second heating device, and a set duration, and the first heating temperature is greater than the second heating temperature.

[0095] S220: Obtain the temperature of the cooking cavity, control the first heating device to rise to the first heating temperature, and adjust the output power of the first heating device according to the temperature and the heating duration; control the second heating device to rise to the second heating temperature, and adjust the output power of the second heating device according to the temperature and the heating duration.

[0096] The temperature of the cooking cavity can be obtained through a temperature detection device. Specifically, the temperature detection device can transmit temperature information into the cooking appliance, and then the current temperature value of the cooking cavity can be obtained through the temperature information. The real-time obtained temperature value can be used for the cooking appliance to control the first heating device and the second heating device, and the control parameters include but are not limited to the output power value, the heating duration, etc.

[0097] Control the second heating device to rise to the second heating temperature, and adjust the output power of the second heating device according to the temperature and heating duration, where the temperature is the temperature of the cooking cavity. The cooking appliance can control the output power of the second heating device to make the second heating device rise to the second heating temperature. And the heating temperature of the second heating device can be detected in real time. When it is detected that the temperature value of the second heating device is equal to the second heating temperature and there is no obvious fluctuation, the output power of the second heating device can be maintained. In one embodiment, when heating vegetables, such as green vegetables, water spinach, etc., the second heating device can be controlled to rise to the second heating temperature. According to the cooking instruction, the cooking instruction can include parameters such as heating power, heating temperature, and heating duration corresponding to different types of vegetables, and control the second heating device to adjust the output power of the second heating device in the first mode. The first mode can be an intermittent heating mode, etc. In the first mode, the second heating device heats in some time periods and stops heating in the remaining time periods, reducing the cooking effect of the second heating device and reducing the cooking effect of the hot air flow on the vegetables, and can prevent the moisture of the vegetables from being quickly dried. Exemplarily, in the heating cycle of the second heating device, the first mode can be, for example, a cycle of 32 seconds. In one cycle, the first heating device is turned on for 20 seconds and stops for 12 seconds. It can be understood that the first mode can also control the power of the second heating device to change periodically, and is specifically selected and designed according to the parameters of the second heating device and the second heating temperature value.

[0098] It can be understood that the temperature value of the second heating device is positively correlated with the power. To make the second heating device rise to the second heating temperature and tend to be stable, the output power of the second heating device can be appropriately adjusted.

[0099] By controlling the output power of the first heating device, control the first heating device to rise to the first heating temperature. And the temperature of the first heating device can be detected in real time. When it is detected that the first heating device rises to the first heating temperature and there is no obvious fluctuation, the output power of the first heating device can be maintained.

[0100] It can be understood that the temperature value of the first heating device is positively correlated with the power. To make the first heating device rise to the first heating temperature and tend to be stable, the output power of the first heating device can be appropriately adjusted.

[0101] During the cooking period, due to a large amount of food being consumed and the frequent use of the cooking appliance, it is easy to have a situation where the next cooking needs to be carried out before the cooking pot has completely cooled down. When the next cooking is carried out again, there is residual heat in the cooking pot and the cooking cavity, and the initial temperature of the cooking cavity is too high. When cooking in the same heating manner, the temperature of the cooking cavity may rise sharply, which is likely to cause the temperature of the cooking cavity to exceed the set range and may also result in situations such as the pot burning, seriously affecting the user's dining experience and posing certain risks. In this embodiment, the first heating device can adjust the output power according to the temperature and the heating duration. The temperature is the temperature of the cooking cavity, which is based on the temperature value at the start cooking moment of the cooking appliance. The first heating device can adjust the output power according to the temperature value of the cooking cavity to adapt to different initial temperatures of the cooking cavity. For example, when the temperature of the cooking cavity is too high, the output power of the first heating device is reduced to slow down the heating rate of the first heating device. This can not only avoid the situation of the pot burning due to too fast heating rate but also ensure that the second heating device can match the first heating device.

[0102] In a more specific way, within the first time period, according to the temperature, the heating mode of the first heating device is determined, and according to the heating mode, the output power of the first heating device is adjusted. The heating mode can be the second mode or the third mode, etc. Among them, the duration of the first time period is less than the set duration. The first time period can be, for example, the time period from the start cooking moment of the cooking appliance to a certain set moment. The second mode can be a continuous heating mode, and the third mode can be an intermittent heating mode. Exemplarily, the first heating device in the second mode can perform continuous heating, and the cooking appliance in the second mode can obtain specific output power, voltage, current and other parameters of the first heating device based on the first heating temperature, so that the first heating device can smoothly implement the heating effect according to the specific parameters.

[0103] It can be understood that the third mode can also control the power of the first heating device to change periodically, which is specifically selected and designed according to the parameters of the first heating device and the first heating temperature value.

[0104] As a more specific implementation manner, please refer to Figure 5 , determining the heating mode of the first heating device according to the temperature may further include step S221 - step S222:

[0105] Step S221: When the temperature is lower than the first set temperature, it is determined that the first heating device heats in the second mode.

[0106] The first set temperature can be pre - stored in the cooking appliance, or the first set temperature can be manually input into the cooking appliance. The user can choose to use the pre - stored parameters or input them by themselves according to the specific food to be cooked. The first preset temperature can be configured to be below 50°C.

[0107] When the temperature is lower than the first preset temperature, determine that the first heating device heats in the second mode. Since the temperature of the cooking cavity is lower than the first preset temperature and the initial temperature of the cooking cavity is low, it will not affect the cooking effect. At the same time, to ensure the heating effect of the first heating device, it can be confirmed that the first heating device heats in the second mode, that is, it is confirmed that the first heating device can continuously heat the food to be cooked in the pot body. Based on the temperature of the cooking cavity, it not only ensures the heating effect on the cooking cavity but also reduces the risk of situations such as the pot burning.

[0108] Step S222: When the temperature is greater than the first set temperature and less than the second set temperature, determine that the first heating device heats in the third mode.

[0109] The second set temperature can be pre-stored in the cooking appliance, or the second set temperature can be manually input into the cooking appliance. The user can choose to use the pre-stored parameters or input them manually according to the specific food to be cooked. The second preset temperature can be configured to be above 100°C.

[0110] When the temperature of the cooking cavity is greater than the first set temperature and less than the second set temperature, determine that the first heating device heats in the third mode. Since the temperature of the cooking cavity is greater than the first set temperature and the initial temperature of the cooking cavity is high, it can affect the cooking effect. To avoid situations such as the pot burning or uneven heating due to the too rapid rise in the temperature of the cooking cavity and the pot body, it can be confirmed that the first heating device heats in the third mode, that is, it is confirmed that the first heating device heats the food to be cooked in the pot body in an intermittent heating mode. Based on the temperature of the cooking cavity, the risk of the pot burning is reduced and the heating effect on the food is ensured.

[0111] More specifically, the cooking parameters of this embodiment further include a first intermittent heating mode, a second intermittent heating mode, a third intermittent heating mode, a first preset temperature, a second preset temperature, and a third preset temperature. Among them, the power adjustment ratios of the first intermittent heating mode, the second intermittent heating mode, and the third intermittent heating mode are different. The power adjustment ratio is the proportion of the actual heating duration in the entire heating cycle. The first preset temperature, the second preset temperature, and the third preset temperature are not equal. The first preset temperature, the second preset temperature, and the third preset temperature can also be stored in the cooking appliance by means such as pre-storing or manual input. The first preset temperature, the second preset temperature, and the third preset temperature are within the range of the first set temperature value and the second set temperature value. The power adjustment ratios of the first intermittent heating mode, the second intermittent heating mode, and the third intermittent heating mode are different.

[0112] When the temperature is greater than the first preset temperature and less than the second preset temperature, it is determined that the first heating device heats in the first intermittent heating mode. The first preset temperature can be 45°C - 55°C, preferably 50°C. The second preset temperature can be 75°C - 85°C, preferably 79°C. Being higher than the first preset temperature can indicate that the remaining heat in the cooking cavity and the pot body will affect heating, but being less than the second preset temperature can indicate that the effect of the remaining heat is not obvious. Compared with continuous heating, the heating rate of the first intermittent heating mode is lower, which can effectively avoid the situation where the heating effect is too rapid. Compared with the second intermittent heating mode and the third intermittent heating mode, the heating effect of the first intermittent heating mode is more significant and can also maintain a certain heating rate. Exemplarily, the first intermittent heating mode has a cycle of 32 seconds. Within one cycle, the first heating device is turned on for 20 seconds and turned off for 12 seconds. The first time period includes multiple consecutive cycles, thereby realizing the intermittent heating of the first heating device and ensuring the heating effect of the cooking appliance.

[0113] When the temperature is greater than the second preset temperature and less than the third preset temperature, it is determined that the first heating device heats in the second intermittent heating mode. The second preset temperature can be 75°C - 85°C, preferably 79°C. The third preset temperature can be 95°C - 105°C, preferably 100°C. Relatively speaking, being higher than the second preset temperature can indicate that the influence of the remaining heat in the cooking cavity and the pot body on the heating effect increases. The second intermittent mode can further increase the interval of the heating time period. Compared with the first intermittent heating mode, the heating rate of the second intermittent heating mode is lower, and the temperature rise amplitude slows down, which can effectively avoid the situation where the heating effect is too rapid. Exemplarily, the second intermittent heating mode has a cycle of 32 seconds. Within one cycle, the first heating device is turned on for 16 seconds and turned off for 16 seconds. The first time period includes multiple consecutive cycles, further increasing the interval of the heating time period to slow down the temperature rise rate.

[0114] When the temperature is greater than the third preset temperature, it is determined that the first heating device heats in the third intermittent heating mode. Compared with the above two situations, being higher than the third preset temperature can indicate that the remaining heat in the cooking cavity and the pot body will have a greater impact on the heating effect. The third intermittent mode can further increase the interval of the heating time period. The heating rate of the first intermittent heating mode is extremely low, and the temperature rise amplitude further slows down, which can effectively slow down the heating rate. Exemplarily, the third intermittent heating mode has a cycle of 32 seconds. Within one cycle, the first heating device is turned on for 10 seconds and turned off for 22 seconds. The first time period includes multiple consecutive cycles, further increasing the interval of the heating time period to slow down the temperature rise rate.

[0115] Based on the different temperatures of the pot body, different heating modes can be selected. Then, the heating parameters of the first heating device are adjusted through different heating modes to achieve different heating effects. Further improve the richness of the cooking modes of the cooking device.

[0116] To improve the cooking effect of the cooking device and the taste of the cooked food. This embodiment further includes:

[0117] In the second time period after the first time period, control the first heating device to heat in the second mode. In the second time period, the pot body has been fully heated, and the second heating device can also generate sufficient hot air circulation. The first heating device and the second heating device can cooperate with each other for heating. To further improve the heating effect and maximize the heating of vegetables to achieve shortening the cooking time and producing a stir-fry effect.

[0118] In the third time period after the second time period, control the first heating device to heat in the third mode. The third time period is for supplementary cooking to further ensure sufficient cooking time and improve the cooking effect on vegetables. At the same time, overcooking can be avoided. Compared with the first time period and the second time period, the cooking heating degree is reduced in the third time period. At the same time, to avoid situations such as the pot being burnt, control the first heating device to heat in the third mode, that is, control the first heating device to heat intermittently to avoid the pot body temperature being too high and causing overcooking.

[0119] Moreover, within the first time period to the third time period, the heating efficiency of the second heating device is higher. The need for air flow heat exchange efficiency is greater, and the rotational speed of the fan can be configured higher to improve the heat circulation effect inside the pot. The fan can be controlled to operate at the first rotational speed. For example, the first rotational speed is 1200 r / min - 1500 r / min. The hot air flow can flow through the vegetables faster, improving the heating effect of the second heating device.

[0120] In one implementation manner, the duration of the first time period is 1 min - 3 min, the duration of the second time period is 2 min - 4 min, and the duration of the third time period is 1 min - 6 min. It can be selected according to the specific implementation object and the working state of the cooking appliance, etc. Exemplarily, when the food to be cooked is water spinach or flowering Chinese cabbage, according to multiple test results, the duration of the first time period can be configured as 1 min, the duration of the second time period can be configured as 3 min, and the duration of the third time period can be configured as 1 min. According to different foods to be cooked, for example, water spinach etc. that require a certain crispy texture, the duration of the second time period needs to be set shorter to reduce the intense cooking time in the second time period to improve the texture.

[0121] Step S230: When the heating duration is greater than the set duration, turn off the first heating device and the second heating device.

[0122] The embodiments of the present application provide a cooking method and a cooking appliance, which perform heating control on a first heating device and a second heating device according to a user's control instruction. When cooking vegetables, by controlling the heating temperatures of both the first heating device and the second heating device, the first heating temperature of the first heating device is made greater than the second heating temperature of the second heating device. The temperature of the hot air flow in the cooking cavity is reduced, thereby reducing the cooking effect of the hot air flow on the vegetables and preventing the moisture of the vegetables from being quickly dried. And the cooking effect of the first heating device is improved to ensure that the vegetables are cooked thoroughly. This setting can both ensure the crispy texture of the vegetables and improve the cooking effect of the vegetables, and can also ensure that the vegetables are cooked thoroughly.

And the cooking effect of the first heating device is improved to ensure that the vegetables are cooked thoroughly.
