[0058] The following details the embodiments of the present application, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0059] In order to enable those skilled in the art to better understand the solution 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 the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0060] The "cooking appliance" used in this embodiment includes, but is not limited to, an air fryer, a rice cooker, an electric rice cooker, a pressure cooker, etc. The present application takes an air fryer as an example of the cooking appliance for elaboration.

[0061] In the prior art, when using a cooking appliance such as an air fryer and at the end of cooking, the temperature inside the inner pot is relatively high, and it is not possible to open the lid and eat immediately. Sometimes, users may even be scalded by the high-temperature food after opening the lid, and it takes a relatively long time to cool the high-temperature food, which also wastes some time.

[0062] Therefore, the inventors of the present application have proposed the cooking method, appliance, control device, and computer-readable storage medium in the embodiments of the present application to improve the above problems. The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application.

[0063] Please refer toFigure 1 , Figure 1 shows the structure of a cooking appliance 1, which may include: a pot body 10, an upper cover 20, a heating element 30, a cooking fan 40, a temperature sensor (not shown in the figure), and a controller (not shown in the figure).

[0064] Please refer to Figure 2 simultaneously. The pot body 10 may include a housing 110 and an inner pot 120. The inner pot 120 is detachably disposed in the housing 110. The interior of the inner pot 120 is hollow to form a cooking cavity 121, which can be used to load food to be cooked. The pot body 10 may be set to a substantially cube or cuboid structure, etc., and the inner pot 120 may be set to a bowl-shaped or cylindrical structure, etc., which is not limited herein. It can be understood that the inner pot 120 may be made of a stainless steel inner pot, a ceramic inner pot, an aluminum alloy inner pot, or a composite material inner pot, etc. The stainless steel inner pot 120 has good corrosion resistance, heat resistance, wear resistance, and easy cleaning. The ceramic inner pot 120 has the characteristics of high temperature resistance, corrosion resistance, good heat preservation performance, easy cleaning, etc., and is also rich in trace elements beneficial to the human body. The aluminum alloy inner pot 120 has the advantages of good thermal conductivity, strong corrosion resistance, and light weight, but it is easy to be scratched and needs to be maintained. The composite material inner pot 120 is composed of multiple materials and has good thermal conductivity, wear resistance, and corrosion resistance. Specific selection can be made according to actual situations, which is not limited herein.

[0065] The upper cover 20 is rotatably disposed on the housing 110 and is used to close the housing 110 and can selectively open or close the cooking cavity 121. The upper cover 20 may be hinged to the housing 110 so that the upper cover 20 is still connected to the housing 110 after being opened, without the user having to separately remove the upper cover 20, which is convenient for the user to operate.

[0066] The heating element 30 is disposed on the housing 110 and is used to heat the inner pot 120. The heating element 30 may be a resistance heating sheet, such as a heating wire, a heating sheet, a heating mesh, etc., or may be electromagnetic induction heating, such as the cooperation of a coil and a magnetic member, etc., which is not limited herein.

[0067] The cooking fan 40 is disposed on the upper cover 20 and is used to establish an air circulation in the inner pot 120 to cool the food in the cooking cavity 121. Specifically, the axis of the cooking fan 40 may be on the same straight line as the axis of the inner pot 120, so that the air blown out by the cooking fan 40 can enter the cooking cavity 121 more, which helps to improve the heat dissipation efficiency of the cooking cavity 121.

[0068] The temperature sensor can be used to obtain the temperature inside the inner container 120, or the temperature of the outer surface of the inner container 120, etc. It can be understood that the temperature sensor can be a thermistor (NTC), a thermocouple, an integrated temperature sensor, a digital temperature sensor, etc., and can be specifically selected according to the actual situation, which is not limited here. One, two or more temperature sensors can be set, which can be respectively used to monitor the temperature at different positions of the inner container 120.

[0069] The controller can be electrically connected to the heating element 30, the cooking fan 40, and the temperature sensor, and issue instructions to the heating element 30, the cooking fan 40, and the temperature sensor. The controller can also be used to obtain the cooking state of the cooking appliance 1, such as the heating state, the cooling state, or the heat preservation state, etc.

[0070] The above-mentioned cooking appliance 1 can obtain the cooking state of the cooking appliance 1 through the controller, and determine whether the cooking appliance 1 enters the cooling state. If the cooking appliance 1 enters the cooling state, the controller can start the cooking fan 40. After the cooking fan 40 is started, it will dissipate heat from the cooking cavity 121 until the temperature in the cooking cavity 121 is less than or equal to the preset temperature, and the controller can control the cooking fan 40 to turn off.

[0071] First Embodiment:

[0072] This embodiment provides a cooking method. Refer to Figure 3 , the method includes the following steps S110 - S140:

[0073] Step S110: Obtain the cooking state of the cooking appliance, and determine whether the cooking appliance enters the cooling state.

[0074] The cooking state includes but is not limited to three states, namely the heating state, the cooling state, and the heat preservation state. The heating state is used to cook the food in the cooking cavity. At this time, the controller can control the heating element to start and heat the inner container, and then cook the food in the cooking cavity. When the cooking appliance finishes cooking the food in the cooking cavity, it can enter the cooling state. The cooling state can be used to cool the food in the cooking cavity. At this time, the controller can control the heating element to turn off and control the cooking fan to turn on, and then cool the food in the cooking cavity, so that the temperature of the food in the cooking cavity is reduced to a level where the user can "open the lid and eat immediately" to avoid scalding the user when eating. Subsequently, it can enter the heat preservation state. The heat preservation state can be used to keep the food in the cooking cavity warm. At this time, the controller can control the cooking fan to turn off and control the heating element to start to perform a heat preservation operation on the food in the cooking cavity to avoid the temperature of the food in the cooking cavity being too low and affecting the user experience.

[0075] It can be understood that the criterion for determining whether the cooking appliance has completed cooking the food in the cooking chamber can be based on the heating time of the heating element defined by the user or preset by the controller. That is to say, when the user starts the cooking appliance to cook food, if the heating time of the heating element reaches the time defined by the user or the heating time of the heating element reaches the time preset by the controller, it can be determined that the cooking appliance has completed cooking the food. At this time, the cooking appliance can enter the cooling state; if the heating time of the heating element does not reach the time defined by the user or the heating time of the heating element does not reach the time preset by the controller, it is determined that the cooking appliance has not completed cooking the food, and at this time, the cooking appliance will not enter the cooling state.

[0076] When the cooking appliance enters the cooling state, step S120 is executed.

[0077] Step S120: Start the cooking fan.

[0078] As mentioned above, after the cooking appliance enters the cooling state, the controller can control the cooking fan to start. After the cooking fan starts, it can cool the food in the cooking chamber. For example, the controller can control the cooking fan to run at a constant speed until the cooking fan is turned off, which can make the operation of the cooking fan more convenient. The controller can also control the cooking fan to run at variable speeds. Specifically, after the cooking fan is turned on, the rotation speed gradually increases. When the rotation speed of the cooking fan reaches the maximum rotation speed, the rotation speed starts to decrease, and this cycle repeats. Since rapidly cooling the food may affect the taste of the food, this can avoid the cooking fan always maintaining a large wind speed to cool the food in the cooking chamber. In addition, it should be noted that during the cooking process, the condensed water in the cooking chamber will accumulate on the upper cover. Therefore, turning on the cooking fan can also accelerate the return of the condensed water on the upper cover to the pot through the wind, reducing the condensed water on the upper cover.

[0079] Step S130: Determine whether the temperature in the cooking chamber is less than or equal to the preset temperature.

[0080] Under the action of the cooking fan, the temperature in the cooking chamber will gradually decrease. The temperature sensor can monitor the temperature in the cooking chamber in real time. In some embodiments, if there are multiple temperature sensors and they are distributed at different positions of the inner liner, the temperature of different regions of the inner liner detected by the multiple temperature sensors can be comprehensively used to determine a more accurate temperature in the cooking chamber. For example, the above comprehensive analysis can be to take the weighted average of each temperature, etc. It can be understood that the above preset temperature can be the temperature defined by the user or a certain temperature preset by the controller.

[0081] If the temperature in the cooking chamber is less than or equal to the preset temperature, step S140 is executed.

[0082] Step S140: Turn off the cooking fan.

[0083] When the temperature in the cooking cavity is less than or equal to the preset temperature, the controller can control the cooking fan to turn off. At this time, the food temperature in the cooking cavity will also be at a relatively low level, meeting the standard that the user can open the lid and eat immediately. At the same time, the condensed water on the upper lid is also at a relatively low level, and when the user opens the upper lid, there will be no dripping of condensed water. For example, when the temperature in the cooking cavity is less than or equal to the preset temperature, the controller can control the cooking fan to turn off. After the cooking fan loses drive, it will gradually stop under the rotational inertia. When the user urgently needs to eat the food in the cooking cavity, the controller can control the cooking fan to stop directly, which can save the time for the cooking fan to continue rotating under inertia. For some foods that require strict control of the cooking duration, this can better ensure the taste of the food.

[0084] The cooking method provided by the embodiment of the present application obtains the cooking state of the cooking appliance, determines whether the cooking appliance enters the cooling state. If the cooking appliance enters the cooling state, the cooking fan is started. When the temperature in the cooking cavity is less than or equal to the preset temperature, the cooking fan is turned off. Since the food temperature in the cooking appliance is at a high level after cooking and is likely to scald the user, after it is obtained that the cooking appliance enters the cooling state, the cooling fan is started to cool the cooking cavity of the cooking appliance until the temperature in the cooking cavity is less than or equal to the preset temperature and then the cooking fan is turned off. This can make the food temperature more suitable when the user opens the cooking cavity. At the same time, the condensed water on the upper lid can be accelerated to flow back into the pot by the wind, reducing the condensed water on the upper lid and reducing the possibility of the user being scalded.

[0085] Second Embodiment:

[0086] Refer to Figure 4 , the embodiment of the present application also provides another control method. The method includes the following steps S210 - S280: 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.

[0087] Step S210: Obtain the cooking state of the cooking appliance and determine whether the cooking appliance enters the cooling state.

[0088] When the cooking appliance enters the cooling state, execute step S220.

[0089] Step S220: Start the cooking fan.

[0090] In a more specific implementation manner, please refer to Figure 5, step S220 may include steps: S221 - S223:

[0091] Step S221: If the cooking appliance enters the cooling state, obtain the temperature of the inner surface of the cooking cavity and / or the inner container.

[0092] That is to say, after the cooking appliance enters the cooling state, the controller can obtain the temperature of the inner surface of the cooking cavity and / or the inner container in real time, and then can generally grasp the real-time temperature of the food in the cooking cavity.

[0093] Step S222: Determine the starting speed of the cooking fan according to the temperature.

[0094] In this embodiment, since different starting speeds of the cooking fan can affect the heat dissipation effect of the cooking fan on the cooking cavity. Specifically, the faster the starting speed of the cooking fan, the more significant the heat dissipation effect of the cooking fan on the cooking cavity. Therefore, the higher the temperature in the cooking cavity, the faster starting speed the cooking fan can adopt to dissipate heat from the cooking cavity, that is, the temperature in the cooking cavity and the starting speed of the cooking fan can be positively correlated. During the heat dissipation process of the cooking fan on the cooking cavity, the temperature in the cooking cavity gradually decreases, and the starting speed of the cooking fan can also decrease accordingly, avoiding excessive cooling of the food in the cooking cavity and affecting the taste of the food.

[0095] For example, the temperature of the inner surface of the cooking cavity and / or the inner container can be divided into two intervals, and each interval corresponds to a starting speed value of the cooking fan. Specifically, taking the temperature in the cooking cavity as a reference, for example, if the temperature in the cooking cavity is greater than T1, the cooking fan operates at a starting speed of R1; if the temperature in the cooking cavity is less than T1, the cooking fan operates at a starting speed of R2, where R2 is less than R1. Specifically, T1 can be 55°C - 75°C, R1 can be 5000 rad / min - 6000 rad / min, and R2 can be 500 rad / min - 5000 rad / min. The specific relationship between temperature and speed can be set according to the actual situation or can be set according to user-defined settings, and is not limited here.

[0096] In some other embodiments, a startup rotation speed of the cooking fan can correspond to different temperature values in the cooking cavity. For example, when the temperature in the cooking cavity is T3, the startup rotation speed of the cooking fan can be R3, and when the temperature in the cooking cavity is T4, the startup rotation speed of the cooking fan can be R4. That is to say, the temperature in the cooking cavity can have a relationship with the startup rotation speed of the cooking fan as R = aT, where R can represent the startup rotation speed of the cooking fan, T can represent the temperature in the cooking cavity, and a can be a preset parameter value or a parameter value input by the user. In this way, more precise rotation speed control can be achieved according to the temperature, which helps to reduce the energy consumption of the cooking appliance.

[0097] Step S223: Start the cooking fan and operate it at the startup rotation speed.

[0098] The higher the temperature on the inner surface of the cooking cavity and / or the inner container, the faster the startup rotation speed of the cooking fan can be controlled. The lower the temperature on the inner surface of the cooking cavity and / or the inner container, the slower the startup rotation speed of the cooking fan can be made. Therefore, the startup rotation speed of the cooking fan can be controlled according to the temperature on the inner surface of the cooking cavity and / or the inner container. This can prevent the cooking fan from rotating at a relatively high startup rotation speed for a long time, thereby reducing the power consumption of the cooking appliance. At the same time, it can also prevent the temperature of the food in the cooking cavity from dropping sharply, which helps to ensure the taste of the food in the cooking cavity.

[0099] In another more specific embodiment, please refer to Figure 6 , step S220 may include steps S224 - S226:

[0100] Step S224: If the cooking appliance enters the cooling state, obtain the temperature on the inner surface of the cooking cavity and / or the inner container.

[0101] Step S224 can refer to the description of step S221 above and will not be elaborated here.

[0102] Step S225: When the temperature is greater than or equal to the first temperature threshold, operate the cooking fan at the first rotation speed.

[0103] Step S226: When the temperature is less than the first temperature threshold and greater than or equal to the second temperature threshold, operate the cooking fan at the second rotation speed, and the second rotation speed is less than the first rotation speed.

[0104] In another embodiment, the temperature of the inner surface of the cooking cavity and / or the inner container can be divided into three intervals. It can be understood that the above intervals are not limited to three, and can also be four, five or more. In this way, heat dissipation and cooling treatment can be carried out more specifically for different temperature intervals of the inner surface of the cooking cavity and / or the inner container, ensuring that the temperature in the cooking cavity can be changed evenly. This can also save the energy consumption of the cooking appliance, and at the same time avoid the problem that the food in the cooking cavity has a poor taste due to sudden cooling. Exemplarily, taking the division of the temperature of the inner surface of the cooking cavity and / or the inner container into three intervals as an example for illustration. Combining with the previous embodiment, for example, the first temperature threshold is defined as T1, the second temperature threshold is defined as T2, the first rotation speed is defined as R1, the second rotation speed is defined as R2, and the third rotation speed is defined as R3.

[0105] Specifically, T1 can be, for example, 55°C - 75°C, T2 can be, for example, 25°C - 55°C, R1 can be, for example, 5000 rad / min - 6000 rad / min, R2 can be, for example, 500 rad / min - 5000 rad / min, R3 can be, for example, 0 rad / min - 500 rad / min. It can be understood that when the temperature in the cooking cavity is less than the second threshold, that is, when the temperature in the cooking cavity is less than T2, the cooking fan can be turned off or run at the third starting rotation speed. The specific relationship between the temperature and the rotation speed can be set according to the actual situation, or can be set according to the user's self-definition, and is not limited here.

[0106] In a more specific embodiment, please refer to Figure 7 , step S220 may include steps S227 - S229:

[0107] Step S227: Obtain the control instruction input by the user.

[0108] The control instruction can be the control of the cooking state of the cooking appliance, the control of the starting rotation speed of the cooking fan, etc., and is not limited here. For example, when the user only uses the cooking appliance to cool the cooked food, at this time, the user can directly input the control instruction to turn on the cooking fan and directly use the cooling state of the cooking appliance to cool the food in the cooking cavity.

[0109] The control instruction can be triggered by pressing the physical button set on the cooking appliance, or can be triggered by voice through the voice receiving module set in the cooking appliance or remotely operated by using a mobile terminal such as a mobile phone, etc., and is not limited here. In some embodiments, the control instruction can also be preset by the user and automatically run after a certain period of time, so that advance reservation can be achieved. When the user is not beside the cooking appliance, the cooking appliance can also enter the working state, improving the convenience of operating the cooking appliance.

[0110] It is understandable that the control instruction may also include instructions for a user-triggered cooking program, such as the selection of a cooking mode, the selection of the operating wind speed of a cooking fan, etc. For example, after the user selects the rice cooking mode and enters the cooling mode, it can be determined that the operating wind speed of the cooking fan is 5000 rad / min. It should be noted that the above-mentioned rice cooking mode may specifically refer to the mode of cooking dry rice, and the subsequent rice may specifically refer to dry rice; after the user selects the porridge cooking mode and enters the cooling mode, since the porridge dissipates heat slower than the rice, it can be determined that the operating wind speed of the cooking fan is 10,000 rad / min; after the user selects the hot dish mode and enters the cooling mode, it can be determined that the operating wind speed of the cooking fan is 7000 rad / min, etc., which is not limited here.

[0111] Step S228: Determine the starting rotational speed of the cooking fan according to the control instruction.

[0112] As described above, since different control instructions may correspond to different starting rotational speeds of the cooking fan. For example, the starting rotational speed of the cooking fan corresponding to the aforementioned rice cooking mode is 5000 rad / min, the starting rotational speed of the cooking fan corresponding to the porridge cooking mode is 10,000 rad / min, and the starting rotational speed of the cooking fan corresponding to the hot rice mode is 7000 rad / min. Different starting rotational speeds of the cooking fan can be specified according to different control instructions. When more heat dissipation is required, such as when dissipating heat from porridge, the starting rotational speed of the cooking fan can be set higher. When less heat dissipation is required, such as when dissipating heat from rice, the starting rotational speed of the cooking fan can be set lower, which can reduce the energy consumption of the cooking appliance.

[0113] Step S229: Control the cooking fan to operate at the starting rotational speed.

[0114] After determining the starting rotational speed of the cooking fan, the cooking fan can operate according to the determined starting rotational speed, which can enable the cooking appliance to adapt to more cooking occasions.

[0115] After step S220, step S230 can be executed.

[0116] Step S230: Obtain the operating duration of the cooking fan.

[0117] The operating duration can be understood as the duration from the start of the cooking fan until the current moment. After the cooking fan starts, it cools the food in the cooking cavity. As the cooking fan operates, the temperature of the food in the cooking cavity gradually decreases.

[0118] Step S240: Determine the operating rotational speed of the cooking fan according to the operating duration.

[0119] As described above, during the heat dissipation process of the cooking fan for the cooking cavity, the longer the running duration of the cooking fan, the lower the temperature in the cooking cavity will be. That is, the running duration of the cooking fan and the temperature in the cooking cavity can be negatively correlated. In other words, the longer the running duration of the cooking fan, the lower the temperature in the cooking cavity. As the running duration of the cooking fan increases, the running speed of the cooking fan can be controlled to decrease, so as to avoid excessive cooling of the food in the cooking cavity and affect the taste of the food.

[0120] For example, if the running duration of the cooking fan is greater than t1, the cooking fan runs at a running speed of r1. If the running duration of the cooking fan is less than t1, the cooking fan runs at a running speed of r2, where r2 is less than r1. Specifically, t1 can be 10 min - 200 min, t2 can be 5 min - 10 min, r1 can be 500 rad / min - 5000 rad / min, and r2 can be 5000 rad / min - 6000 rad / min. The specific relationship between the running duration and the speed can be set according to the actual situation or according to user-defined settings, and is not limited here.

[0121] It should be noted that the above example is only one case. In some other embodiments, the running duration of the cooking fan can also be divided into multiple gradients. For example, it can be greater than t1, less than t1 and greater than t2, less than t2, etc. There should be a corresponding speed for each gradient. That is to say, the running duration of the cooking fan can have a relationship with the running speed of the cooking fan as r = bt, where r can represent the running speed of the cooking fan, t can represent the running time of the cooking fan, and b can be a preset parameter value or a parameter value input by the user. In this way, more precise speed control can be achieved according to the running time of the cooking fan, which helps to reduce the energy consumption of the cooking appliance.

[0122] Step S250: Control the cooking fan to run at the running speed.

[0123] The running speed can be controlled according to the running duration, so that the temperature in the cooking cavity can decrease evenly over time, which is convenient for accurately grasping the temperature in the cooking cavity, and then enables the user to more accurately predict the temperature of the food in the cooking cavity.

[0124] Step S260: Determine whether the temperature in the cooking cavity is less than or equal to a preset temperature.

[0125] If the temperature in the cooking cavity is less than or equal to the preset temperature, execute Step S270. If the temperature in the cooking cavity is greater than the preset temperature, execute Step S280.

[0126] Step S270: Turn off the cooking fan.

[0127] Step S280: Obtain the cooling duration when entering the cooling state.

[0128] The cooling duration here can be understood as the time elapsed since the cooking appliance entered the cooling state until the current moment. It can be understood that since the cooking appliance can be used to cook various types of foods, for example, when the cooking appliance cooks foods such as soups, generally speaking, the ideal temperature for eating soups is relatively high to maintain the taste of the soups. Therefore, when the cooking appliance cooks soups, simply comparing the temperature in the cooking cavity with the preset temperature is not conducive to preserving the taste of the soups. Therefore, by introducing the cooling duration, it can be determined whether to turn off the cooking fan.

[0129] If the cooling duration is greater than or equal to the preset duration, execute step S270.

[0130] The preset duration can be set to 10 min - 200 min (minutes). Of course, this duration can also be a duration defined by the user, and this duration can be shorter or longer, and can be specifically determined according to the types of foods cooked in the cooking appliance to ensure that the food in the cooking cavity has a good taste when the end user opens the lid.

[0131] The cooking method provided by the embodiment of the present application determines whether the cooking appliance enters the cooling state by obtaining the cooking state of the cooking appliance. If the cooking appliance enters the cooling state, the cooking fan is started. When the temperature in the cooking cavity is less than or equal to the preset temperature, the cooking fan is turned off. Since the temperature of the food in the cooking appliance is at a high level after the cooking appliance finishes cooking and is likely to scald the user, when it is obtained that the cooking appliance enters the cooling state, the cooling fan is started to cool the cooking cavity of the cooking appliance until the temperature in the cooking cavity is less than or equal to the preset temperature or the cooling duration is greater than or equal to the preset duration, and then the cooking fan is turned off. In this way, the temperature of the food is more appropriate when the user opens the cooking cavity, reducing the possibility of the user being scalded. At the same time, the condensed water on the upper cover can be accelerated to flow back into the pot by the wind, reducing the condensed water on the upper cover, and at the same time ensuring the taste of the food.

[0132] Third Embodiment:

[0133] The embodiment of the present application also provides another control method. Refer to Figure 8 , the method includes the following steps S310 - S330: 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.

[0134] Step S310: Obtain the cooking program currently executed by the cooking appliance. When the cooking program is completed, determine that the cooking appliance enters the cooling state.

[0135] As mentioned above, the cooking program may refer to the program when the cooking appliance heats the cooking cavity. For example, when the control instruction is input to the rice cooking mode, the cooking appliance executes the cooking program to cook raw rice into cooked rice. In this embodiment, whether the cooking program is completed can be judged by parameters such as cooking time and the temperature in the cooking cavity. For example, after the control instruction is input to the rice cooking mode, when the cooking time reaches 0.5 hours, it can be determined that the cooking program is completed; for another example, after the control instruction is input to the rice cooking mode, when the temperature in the cooking cavity reaches 120 °C, it can be determined that the cooking program is completed.

[0136] Since the cooling state is used to cool the cooked food so that the user can eat immediately after opening the lid, it is possible to confirm whether the food has been cooked before entering the cooling state. That is, before determining that the cooking appliance enters the cooling state, it can be first determined whether the cooking program is completed, so as to avoid the cooking appliance entering the cooling state when the food is not cooked, resulting in the user not being able to obtain the cooked food, which also avoids the user not being able to eat immediately after opening the lid due to the food not being cooked.

[0137] Step S320: If the cooking appliance enters the cooling state, start the cooking fan.

[0138] In a more specific embodiment, please refer to Figure 9 , if the cooking appliance enters the cooling state, starting the cooking fan may include steps: S321 - S323:

[0139] Step S321: Obtain the program parameters of the cooking program.

[0140] The program parameters may include, but are not limited to, one or more of the total program duration, raw material grade, and heating duration in the program.

[0141] The total program duration can be understood as the time elapsed from when the cooking appliance starts working to the current moment. The heating duration in the program can be understood as the time elapsed from when the cooking appliance starts heating to the current moment.

[0142] The raw material grade can be understood as parameters such as the solid-liquid ratio and liquid turbidity in the cooking cavity. For example, when cooking rice, rice and water are put into the cooking cavity together. At this time, the ratio of solids to liquids in the cooking cavity is A. As cooking progresses, this ratio will change. When cooking rice is completed, the ratio of solids to liquids in the cooking cavity is B. Another example is when cooking soup, raw materials such as vegetables and meats and water are put into the cooking cavity together. At this time, the turbidity of the liquid in the cooking cavity is C. As cooking progresses, this turbidity will change. When cooking soup is completed, the turbidity of the liquid in the cooking cavity is D.

[0143] Step S322: Determine the operating speed of the cooking fan according to the program parameters.

[0144] As mentioned above, since the cooking cavity will still be affected by the residual temperature of the heating element after cooking is completed and will be heated for a certain period of time, the operating speed of the fan can be determined according to the program parameters to avoid overcooking the food in the cooking cavity and affecting the taste of the food.

[0145] For example, the operating speed of the cooking fan can be determined according to the total program duration. When the total program duration is greater than 1 h, the cooking fan can be controlled to operate at 5000 rad / min. When the total program duration is greater than 2.5 h, the cooking fan can be controlled to operate at 500 rad / min.

[0146] Another example is that the operating speed of the cooking fan can be determined according to the raw material grade. When the raw material grade is B when cooking rice, that is, the rice is just cooked at this time, the cooking fan can be controlled to operate at 5000 rad / min. The residual temperature in the cooking cavity will continue to heat the just-cooked rice, and the raw material grade will then change. For example, when the raw material grade changes from B to C, where C is greater than B, the cooking fan can be controlled to operate at 500 rad / min at this time.

[0147] Another example is that the operating speed of the cooking fan can be determined according to the heating-up duration in the program. When the heating-up duration in the program is greater than 0.8 h, the cooking fan can be controlled to operate at 5000 rad / min. When the heating-up duration in the program is greater than 1.2 h, the cooking fan can be controlled to operate at 500 rad / min.

[0148] Step S323: Start the cooking fan and operate it at the operating speed.

[0149] Step S330: When the temperature in the cooking cavity is less than or equal to the preset temperature, turn off the cooking fan 。

[0150] The cooking method provided by the embodiments of the present application determines whether the cooking appliance enters a cooling state by obtaining the cooking state of the cooking appliance. If the cooking appliance enters the cooling state, the cooking fan is started, and when the temperature in the cooking cavity is less than or equal to a preset temperature, the cooking fan is turned off. Since the temperature of the food in the cooking appliance is at a high level after cooking and is likely to scald the user, after it is obtained that the cooking appliance enters the cooling state, the cooling fan is started to cool the cooking cavity of the cooking appliance, and the cooking cavity is cooled according to the program parameters, which can prevent the food in the cooking cavity from being overcooked. In this way, when the user opens the cooking cavity, the temperature of the food is relatively appropriate, the taste of the food is ensured, and at the same time, the condensed water on the upper cover can be accelerated to flow back into the pot by the wind, reducing the condensed water on the upper cover and reducing the possibility of the user being scalded.

[0151] Fourth Embodiment:

[0152] Based on the above cooking method, the embodiments of the present application further provide another control method. Refer to Figure 10 , the method includes the following steps S410 - S430: 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 embodiments. The specific description of these same or corresponding implementation steps can refer to the content provided in the above embodiments, and will not be elaborated in this embodiment.

[0153] Step S410: Obtain the cooking state of the cooking appliance and determine whether the cooking appliance enters a cooling state.

[0154] Step S420: If the cooking appliance enters the cooling state, start the cooking fan and control the cooking fan to be alternately turned on or off at a predetermined period.

[0155] The predetermined period can be the period preset by the cooking appliance. The predetermined period can be a fixed period or a variable period. For example, when the predetermined period is a fixed period, such as each predetermined period is 0.5 min - 3 min, at this time, it can be to control the cooking fan to run for 1 min and then turn it off for 1 min, or it can be to control the cooking fan to run for 1 min and turn it off for 0.5 min, etc. Another example is when the predetermined period is a variable period, such as the first period is 0.5 min - 1 min, and the subsequent period is 10 s - 30 s, and so on in a repeated cycle. At this time, it can be to control the cooking fan to run for 0.6 min, then turn it off for 0.7 min, then control the cooking fan to run for 12 s, then turn it off for 20 s, and repeat in a cycle according to these two predetermined periods. This can avoid the cooking fan being turned on for a long time, resulting in noise pollution. It can be understood that the predetermined period can also be a period defined by the user.

[0156] Step S430: When the temperature in the cooking cavity is less than or equal to the preset temperature, turn off the cooking fan.

[0157] The cooking method provided by the embodiment of the present application determines whether the cooking appliance enters a cooling state by obtaining the cooking state of the cooking appliance. If the cooking appliance enters the cooling state, the cooking fan is started. When the temperature in the cooking cavity is less than or equal to the preset temperature, the cooking fan is turned off. Since the food temperature in the appliance is at a high level after the cooking appliance finishes cooking and is likely to scald the user, when it is obtained that the cooking appliance enters the cooling state, the cooling fan is started to cool the cooking cavity of the cooking appliance. At the same time, the cooking fan is controlled to be alternately turned on or off at a predetermined period, which can reduce the noise pollution of the cooking appliance. Until the temperature in the cooking cavity is less than or equal to the preset temperature, the cooking fan is turned off. This can make the temperature of the food more suitable when the user opens the cooking cavity. At the same time, the condensed water on the upper cover can be accelerated to flow back into the pot by the wind, reducing the condensed water on the upper cover and reducing the possibility of the user being scalded.
