[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, so that the food can achieve the cooking effect of a frying pan without oil, thereby reducing the intake of grease and making the food healthier. In addition, the air fryer does not require the use of oil and water, is simple and convenient to operate, and the cooking speed is also very fast.

[0003] In the prior art, an air fryer drives air flow through a blower located in the upper part. The air flow passes through a heating device to generate hot air flow, and the hot air flow can continuously heat and cook the food. When cooking meat products such as bacon in an air fryer, it is difficult for the hot air flow to cook the meat products thoroughly, resulting in poor cooking effect. However, when the air fryer directly heats the pot body to complete the cooking of meat products, it may cause the temperature of the pot body to be unstable, easily resulting in the bottom of the pot being burnt and some ingredients not being cooked thoroughly.

[0056] Embodiment

[0057] An embodiment of the present 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 meat products such as beef through high-speed circulating hot air flow, so that the food can achieve the cooking effect of a fryer without oil.

[0058] Please refer to together Figure 2 , 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 disposed within 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 disposed on a side of the second heating device 530 away from the pot body 510, and the temperature detection device 550 can be disposed on the surface of the pot body 510.

[0059] 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.

[0060] 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 pot body 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 pot body 510 can be pushed into the content cavity 583 through the first opening.

[0061] The pot body 510 can be used to hold the food to be cooked. In this embodiment, the pot body 510 can be made of a non-stick coating material. The surface of the non-stick coating pot body is coated with an artificial coating, which is very smooth, making the fryer easier to clean and convenient for cooking, and can also reduce the unnecessary use of grease. The pot body 510 can also be made of stainless steel. The stainless steel pot body has strong rust prevention ability and good corrosion resistance. The pot body 510 made of stainless steel material is also more durable and easy to clean. The pot body 510 can also be made of aluminum alloy. The pot body 510 made of aluminum alloy material is light in weight and has good heat conduction effect, which can quickly conduct heat and is suitable for cooking in a short time. The pot body 510 can also be made of carbon steel. The pot body 510 made of carbon steel material has high weight resistance, wear resistance and corrosion resistance, and can adapt to more cooking needs and occasions.

[0062] In this embodiment, the pot body 510 can also include a fry basket (not shown in the figure). The fry basket can be a kitchenware accessory for baking food inside the cooking appliance 500. The fry 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 pot body 510 has a convex structure. When the fry basket is placed in the cooking cavity, the bottom of the fry basket can abut against the convex structure to lift the fry basket. Then the food to be cooked is placed on the surface of the fry basket facing the blower 540. The fry 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 pot body 510 having a convexity, the fry 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 the influence of food stacking on each other.

[0063] The first heating device 520 can be arranged on the base 581. Further, the first heating device 520 can be directly abutted against the pot body 510, and then the first heating device 520 can directly heat the pot body 510. Compared with heat transfer by air flow, the heat conduction efficiency from the first heating device 520 to the pot body 510 can be improved, and then the heating effect of the first heating device 520 can be improved.

[0064] Please continue to refer to Figure 2 , the second heating device 530 is arranged on the top cover 582, and the blower 540 is also arranged on the top cover 582, and the blower 540 is located on the 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. The second heating device 530 is energized to generate heat, and 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.

[0065] 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, and 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, and the output shaft of the driving device 541 passes through the mounting hole 585. The fan blade 542 may be disposed on the output shaft and rotate 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 realize internal heat circulation.

[0066] In one embodiment, the output shaft of the driving device 541 passes through the mounting hole 585, and the diameter of the output shaft may be slightly smaller than the aperture of the mounting hole 585, so that the output shaft can smoothly pass through the mounting hole 585, ensuring that the output shaft can rotate smoothly within the mounting hole 585, and also avoiding heat escaping from the mounting hole 585 and ensuring the energy utilization rate.

[0067] Preferably, the mounting hole 585 is opened on the top cover 582 and may be disposed at the center of the top cover 582. For example, the top cover 582 may be circular, and the axes of the mounting hole 585 and the top cover 582 coincide with each other, so that the distances from the output shaft disposed on the mounting hole 585 to all parts of the edge of the top cover 582 are 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 thus generating a larger air flow range.

[0068] The driving device 541 in this embodiment may adopt a DC brushless motor. A DC brushless motor is a DC motor using electronic commutation and has the following advantages compared with traditional AC motors:

[0069] First, the DC brushless motor has a higher energy efficiency ratio: Since there is no need to adjust the current reverse 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 substance (such as a carbon brush) inside the motor, the friction loss during the operation of the motor is smaller and the lifespan is longer. Third, 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 and can adapt to different load and working condition requirements.

[0070] It is understandable that within the normal power range, the power of the blower 540 determines the rotational speed of the drive device 541. By changing the power of the blower 540, the rotational speed of the blower 540 can be adjusted, thereby changing the flow rate of the air flow within the pot body 510, further changing the flow rate of the internal heat cycle, and changing the cooking effect of the cooking appliance 500.

[0071] In one embodiment, both the first heating device 520 and the second heating device 530 can be heating tubes. When the heating tubes are energized, heat is generated, which promotes heat exchange of the passing air flow to achieve hot air circulation.

[0072] 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 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.

[0073] 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, 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 on 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 junctions are different, an electromotive force will be generated in the loop, which can indicate the temperature measurement when the voltage changes. It is understandable that the selection and design of the temperature detection device 550 can be based on the specific implementation scenario and measurement target, etc., and this embodiment does not limit it.

[0074] 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 use the temperature measurement result of the temperature detection device 550 to adjust the heating parameters.

[0075] Please refer to Figure 2 , 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 the control instructions of 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.

[0076] 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 manipulate 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.

[0077] This embodiment also provides a cooking method, which can be applied to the aforementioned cooking appliance 500. Please refer to Figure 3 , the cooking method includes the following steps S110-S120:

[0078] 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 less than the second heating temperature.

[0079] The cooking appliance can pre-store several preset programs. Each preset program can be used to process specific ingredients respectively, such as the preset programs for processing meat products like bacon and beef. 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.

[0080] 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. 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 to operate according to the operating parameters until the second heating device stops heating.

[0081] 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.

[0082] 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.

[0083] When cooking meat products, the first heating temperature is lower than the second heating temperature. Since the first heating device can directly heat the pot body so that the food in the pot body can be cooked. Different from the second heating device that heats the food in the pot body through a heating air flow. In comparison, the heat conduction rate of the first heating device is better. The setting that the first heating temperature is lower than the second heating temperature can prevent the heating effect of the first heating device from far exceeding that of the second heating device, and can avoid the heating effect of the first heating device from being too rapid, resulting in the phenomenon of the pot burning. The heating effects of the first heating device and the second heating device can be balanced by configuring a temperature difference, which can not only avoid phenomena such as the pot burning, but also ensure that the meat products are cooked thoroughly. For example, when the food to be cooked is bacon, 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 - 170°C, preferably 180°C. The second heating temperature can be 160°C - 200°C, preferably 150°C, and the first heating temperature is 20°C - 40°C less than the second heating temperature, preferably 30°C. Since the heat loss of the direct heat conduction of the first heating device is less and the heat conduction effect is better compared with the heat transfer method of the second heating device through air. By configuring a temperature difference between the first heating temperature and the second heating temperature, the upper and lower heat differences of the pot body can still be within the set range, which can avoid situations such as the pot burning and ensure the consistency of the heating effect of the food to be cooked.

[0084] The set duration can be the operating duration of the cooking appliance. By adjusting the power-on time and power-off time 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, which are not limited in this embodiment.

[0085] 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, which are not limited in this embodiment and are adjusted according to specific cooking requirements, etc.

[0086] Step S120: When the heating duration is greater than the set duration, turn off the first heating device and the second heating device.

[0087] 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, stop the power supply of the first heating device and the second heating device, that is, complete the heating process, so as to prevent the device from further heating, ensure the cooking effect of the food to be cooked, and prevent overcooking.

[0088] In another embodiment, when the heating duration is greater than the set duration, the cooking appliance can report to the user situations such as the end of work through sound or visual cues, reminding the user to take corresponding measures.

[0089] 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. The specific elaboration of these same or corresponding implementation steps can refer to the content provided in the above embodiment, and will not be elaborated in this embodiment.

[0090] 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 the set duration, and the first heating temperature is less than the second heating temperature.

[0091] S220: Obtain the temperature of the cooking cavity, control the second heating device to rise to the second heating temperature and heat in the first mode, control the first heating device to rise to the first heating temperature, and adjust the output power according to the temperature and the heating duration.

[0092] 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.

[0093] Control the second heating device to rise to the second heating temperature and heat in the first mode. The cooking appliance controls the output power of the second heating device so that the second heating device rises 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, maintain the output power of the second heating device. The first mode can be a continuous heating mode or an intermittent heating mode, etc. More specifically, the second heating device in the first mode can continuously heat, and the first mode can obtain specific output power, voltage, current and other parameters of the second heating device based on the second heating temperature, and the second heating device can smoothly implement the heating effect according to the first mode. It can be understood that the first mode can also make the power of the second heating device change periodically, and is specifically selected and designed according to the parameters of the second heating device and the second heating temperature value.

[0094] It is understandable that the temperature value of the second heating device is positively correlated with the power. To raise the temperature of the second heating device to the second heating temperature and tend to be stable, the output power of the second heating device can be appropriately adjusted.

[0095] By controlling the output power of the first heating device, the temperature of the first heating device is raised 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 temperature of the first heating device has risen to the first heating temperature and there is no obvious fluctuation, the output power of the first heating device can be maintained.

[0096] It is understandable that the temperature value of the first heating device is positively correlated with the power. To raise the temperature of the first heating device to the first heating temperature and tend to be stable, the output power of the first heating device can be appropriately adjusted.

[0097] During the cooking period, due to a large amount of food consumption and frequent use of the cooking appliance, it is easy to have a situation where the next cooking needs to be carried out before the pot body is completely cooled. When the next cooking is carried out again, there is residual heat in the pot body and the cooking cavity, and the initial temperature of the cooking cavity is too high. When cooking in the same heating mode, 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 cause situations such as the pot being burnt, seriously affecting the user's dining 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, 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 being burnt due to too fast heating rate, but also ensure that the second heating device can match the first heating device.

[0098] In a more specific manner, 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.

[0099] It is understandable 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.

[0100] 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 steps S221 - S222:

[0101] 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.

[0102] The first set temperature can be pre - stored in the cooking pot, or the first set temperature can be manually input. The user can choose to use the pre - stored parameters or input by themselves according to the specific food to be cooked. The first preset temperature can be configured to be below 50°C.

[0103] When the temperature is lower than the first preset temperature, it is determined 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. 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 the pot burning, etc.

[0104] Step S222: When the temperature is greater than the first set temperature and less than the second set temperature, it is determined that the first heating device heats in the third mode.

[0105] The second set temperature can be pre - stored in the cooking pot, or the second set temperature can be manually input. The user can choose to use the pre - stored parameters or input by themselves according to the specific food to be cooked. The second preset temperature can be configured to be above 100°C.

[0106] When the temperature of the cooking cavity is greater than the first set temperature and less than the second set temperature, it is determined 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, 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 in an intermittent heating mode. Based on the temperature of the cooking cavity, it reduces the risk of the pot burning and ensures the heating effect on the food.

[0107] 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 of pre-storage or manual input, etc. 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.

[0108] 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 indicates that the remaining heat in the cooking cavity and the pot body will affect the heating, but being less than the second preset temperature indicates 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. In 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.

[0109] 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 indicates 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. In 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 to further increase the interval of the heating time period and slow down the temperature rise rate.

[0110] When the temperature is greater than the third preset temperature, it is determined that the first heating device heats in the third interval heating mode. Compared with the above two cases, a temperature higher than the third preset temperature indicates that the remaining heat in the cooking cavity and the pot body will have a greater impact on the heating effect. The third interval mode can further increase the interval of the heating period. The heating rate of the first interval heating mode is extremely low, and the temperature rise further slows down, which can effectively slow down the heating rate. Exemplarily, the third interval heating mode has a cycle of 32 seconds. Within one cycle, the first heating device is turned on for 10 seconds and stopped for 22 seconds. The first period includes a plurality of consecutive cycles, further increasing the interval of the heating period to slow down the temperature rise rate.

[0111] The heating mode can be selected according to different pot body temperatures. 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.

[0112] To improve the cooking effect of the cooking device and the taste of the cooked food. This embodiment further includes:

[0113] In the second period after the first period, control the first heating device to heat in the second mode. In the second period, the pot body has been sufficiently 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, heat the meat products to the maximum extent to shorten the cooking time and produce a stir-fry effect.

[0114] Moreover, in the first period and the second 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 in the pot body. The fan can be controlled to operate at the first rotational speed. For example, the first rotational speed is 1200r / min - 1500r / min. The hot air can flow through the food to be cooked faster, improving the heating effect of the second heating device.

[0115] In the third period after the second period, control the first heating device to heat in the third mode. The third period is for supplementary cooking, to further ensure sufficient cooking time and improve the cooking effect on meat products. At the same time, overcooking can be avoided. Compared with the first period and the second period, the cooking heating degree is reduced in the third period. Also, 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 prevent the pot body temperature from being too high and causing overcooking.

[0116] During the third period, the heating efficiency of the second heating device decreases. The need for the air flow heat exchange efficiency weakens, and the rotational speed of the blower can be configured to be lower. The blower is controlled to operate at a second rotational speed, and the first rotational speed is greater than the second rotational speed. For example, the second rotational speed is 800 r / min - 1000 r / min. The hot air flow can flow more slowly to the food to be cooked, slowing down the heating rate of the second heating device.

[0117] In one implementation, the duration of the first period is 1 min - 3 min, the duration of the second period is 2 min - 4 min, and the duration of the third 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 a stir-fried pork with chili peppers, according to multiple test results, the duration of the first period can be configured to be 2 min, the duration of the second period can be configured to be 2 min, and the duration of the third period can be configured to be 1 min. Or, when the food to be cooked is preserved meat, according to multiple test results, the duration of the first period can be configured to be 2 min, the duration of the second period can be configured to be 1 min, and the duration of the third period can be configured to be 1 min. Depending on the food to be cooked, for example, to improve the crispiness of the streaky pork and reduce the fat of the streaky pork, the intense cooking time of the second period is increased to improve the taste.

[0118] Step S230: When the heating duration is greater than the set duration, turn off the first heating device and the second heating device.

[0119] The embodiments of the present application provide a cooking method and a cooking appliance, which perform heating control on the first heating device and the second heating device according to a user's control instruction. When cooking meat products, by controlling the heating temperatures of the first heating device and the second heating device, the first heating temperature of the first heating device is made less than the second heating temperature of the second heating device. The cooking effect of the first heating device on the meat products is reduced, and the rapid heating of the pot body to cause burning of the pot is avoided. Due to the different heat transfer efficiencies of the two heating devices, by controlling the way of generating a temperature difference, the first heating device and the second heating device cooperate with each other to ensure that the meat products are cooked thoroughly.

[0120] The embodiments of the present application propose a control device 400 for a cooking appliance. Please refer to Figure 6, the cooking appliance may include a pot body, a first heating device, a second heating device, a blower, and a temperature detection device. The pot body is placed inside the housing of the cooking appliance. The first heating device is located below the pot body and can heat the pot body. Heat can be conducted through the pot body to the food to be cooked inside the pot body, so that the meat product can be cooked thoroughly. The second heating device is located above the pot body. The blower is used to form an air flow circulation inside the pot body, and the blower can be arranged on the side of the second heating device away from the pot body. The blower drives the air flow, and the second heating device heats the air flow to form a hot air flow, and the hot air flow can act on the meat product inside the pot body. The temperature detection device can be arranged on the surface of the pot body, and the temperature detection device can obtain the temperature of the cooking cavity. In a specific embodiment, the control device 400 includes an execution module 410 and a shutdown module 420.

[0121] The execution module 410 is configured to turn on the first heating device, the second heating device, and the blower in response to a cooking instruction issued by the user; 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 less than the second heating temperature;

[0122] The shutdown module 420 is configured to turn off the first heating device and the second heating device when the heating duration is greater than the set duration.

[0123] In summary, for the control device 400 of the cooking appliance provided in the embodiments of the present application, by controlling the heating of the first heating device and the second heating device according to the control instruction of the user, when cooking the meat product, 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 less than the second heating temperature of the second heating device. This reduces the cooking effect of the first heating device on the meat product and avoids the pot body from heating up rapidly and causing the pot to burn. Due to the different heat transfer efficiencies of the two heating devices, by controlling the way of generating a temperature difference, the first heating device and the second heating device cooperate with each other to ensure that the meat product is cooked thoroughly.
