[0049] In recent years, air fryers have become more and more popular and have become a hot kitchen appliance, and their multifunctional applications are also constantly expanding, such as fermentation, air drying, etc. However, the related art does not introduce the stewing function of air fryers.

[0071] In order to better understand the above technical solution, exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0072] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0073] In order to realize the stewing function of the air fryer, the embodiment of the present application proposes a cooking method. The cooking method is used for the air fryer, and the air fryer includes a shell and a hot air device. A cooking cavity is arranged in the shell, and the hot air device is used to heat the food in the cooking cavity. Figure 1 and Figure 2 , the cooking method comprises the following steps:

[0074] S100, boiling step: controlling the hot air device to operate in a first working condition to heat the liquid in the cooking cavity to boiling;

[0075] In the embodiment of the present application, the hot air device generally includes a fan and a heating element. The high temperature is provided by the heating element, and the fan causes the high temperature air in the cooking cavity to flow. Of course, the hot air device can also be other combined devices that can provide high-temperature flowing air for heating food materials, which is not required here. It should be noted that the embodiment of the present application adopts water-insulated stewing, that is, an inner pot for holding liquid is provided in the cooking cavity, and the liquid can be selected as water. The user places the stew pot containing food materials, water, etc. in the above liquid. The hot air device is used to heat the liquid, and the liquid heats the food materials and water in the stew pot by heat conduction.

[0076] Combination Figure 2 , Figure 2 Middle curve t A Indicates the temperature of the hot air (air) in the cooking chamber, curve t B Curve V represents the wind speed of hot air in the cooking cavity.

[0077] In the first working condition, the hot air device makes the air in the cooking cavity have a first temperature t1, and the air flows at a first wind speed V1. For example, under standard atmospheric pressure, when the liquid in the inner pot of the cooking cavity is water, the boiling temperature of water is 100°C, the first temperature t1 may be approximately 200°C-300°C, the first wind speed V1 is approximately 2m / s-9m / s, and the air has a higher temperature than the boiling temperature and runs at a faster speed, which is conducive to quickly boiling the water, shortening the heating time, and improving the heating efficiency and heat utilization rate.

[0078] S200, stewing step: controlling the hot air device to operate in a second working condition so that the liquid in the cooking chamber is maintained in a preset temperature range for a preset time, wherein the value of the preset temperature range is lower than the boiling temperature of the liquid.

[0079] In the second working condition, the hot air device makes the air in the cooking cavity have a second temperature t2, and the air flows at a second wind speed V2. It can be understood that the second temperature t2 is less than the first temperature t1, and the second wind speed V2 is less than the second wind speed V2. Exemplarily, under standard atmospheric pressure, when the liquid in the inner pot of the cooking cavity is water, the boiling temperature of water is 100°C, the first temperature t1 can be approximately 200°C-300°C, the first wind speed V1 is approximately 2m / s-9m / s, and the second temperature t2 can be selected as 100°C-150°C, and the second wind speed V2 is approximately 0.1m / s-1.5m / s. Compared with the first working condition, the air in the second working condition has a relatively low temperature and runs at a lower speed, which is conducive to keeping the liquid in the cooking cavity at a preset temperature below the boiling temperature, reducing the loss of the liquid in the cooking cavity, and enabling it to continuously heat the ingredients, water, etc. in the stew pot at a preset temperature. For example, under standard atmospheric pressure, when the liquid in the inner pot of the cooking cavity is water, the boiling temperature of water is 100°C, and the preset temperature can be 95°C-99°C.

[0080] It can be seen that under the first operating condition, the temperature of the center of the food rises rapidly. Under the second operating condition, by controlling the hot air device, the air is run at a lower temperature and a lower speed for a preset time, so that the temperature of the center of the food is stabilized at the preset temperature, and slow cooking is achieved, which is conducive to the full dissolution of the flavor and nutrients of the ingredients.

[0081] The embodiment of the present application controls the hot air device to operate in the first operating condition and the second operating condition successively. After the liquid in the cooking cavity is heated to boiling, it is continuously heated at a preset temperature lower than the boiling temperature for a preset time, so that the liquid in the cooking cavity is first quickly heated up under high heat and then simmered over low heat, thereby realizing the stewing operation of the air fryer and enriching the functions of the air fryer.

[0082] Please refer to Figure 3 In an optional embodiment of the present application, before the boiling step, the cooking method further comprises:

[0083] S300, obtaining food information in the cooking cavity;

[0084] Optionally, the food information can be obtained by intelligent recognition of the air fryer or input by the user.

[0085] Optionally, the food information includes food type information and / or volume information. For example, the food used for stewing soup may be spareribs, chicken, chestnuts, etc. Different food materials have different properties, such as water content, fat content, etc. The volume information characterizes the size of the food material. Based on the food type information and / or volume information, different temperatures and wind speeds are used for cooking in a targeted manner, so as to give full play to the characteristics of the food material.

[0086] S400: Determine operating parameters of a first operating condition and a second operating condition of the hot air device according to food information.

[0087] It can be understood that a pre-set instruction list is stored in the memory of the air fryer, and the instruction list reflects a set of information about a plurality of ingredients, a set of operating parameters of the first working condition and the second working condition of the hot air device, and a mapping relationship between the two. That is, after obtaining the information about the ingredients in the cooking cavity, the processor can call the corresponding operating parameters from the instruction list according to the information about the ingredients to control the hot air device.

[0088] Exemplarily, the instruction list includes a mapping relationship between spare ribs and the operating parameters of the first and second operating conditions of the hot air device. When the acquired food information is spare ribs, the operating parameters of the first and second operating conditions of the hot air device corresponding to the spare ribs are retrieved.

[0089] Furthermore, the ingredients used for stewing soup often include main ingredients (such as ribs, chicken, etc.) and auxiliary ingredients (seasonings, spices). The instruction list may include a variety of arrangements and combinations of main ingredients and auxiliary ingredients, and include a collection of the operating parameters of the first working conditions and second working conditions of the above-mentioned multiple situations and multiple hot air devices, so as to improve the functionality of the air fryer and achieve more precise control.

[0090] When the acquired food information is volume information, the instruction list includes a mapping relationship between multiple volume intervals and the operating parameters of the first and second working conditions of the hot air device. When the acquired volume information falls into a certain interval, the operating parameters of the first and second working conditions of the hot air device corresponding to the interval are retrieved.

[0091] Reference Figure 4 In an optional embodiment, the air fryer further includes a camera module, and the step of obtaining food information in the cooking cavity includes:

[0092] S301, controlling the camera module to take pictures of the food in the cooking cavity;

[0093] In this embodiment, the camera module can shoot the food in the cooking cavity. A through hole is opened at the top of the cooking cavity, and the lens assembly of the camera module can shoot the items in the cooking cavity through the through hole. To protect the camera module, the through hole is covered with high temperature resistant glass, which does not affect the function of the camera module.

[0094] Commonly, the stew pot includes a pot body and a pot cover. The pot body is formed with a receiving groove for accommodating food and clean water. The pot cover can be covered on the top of the pot body to cover the notch of the receiving groove to reduce water loss. Before starting the air fryer or before performing the boiling step, the user can first place the pot body containing food into the liquid in the inner pot of the cooking cavity, and cover the pot cover after the shooting is completed to cook.

[0095] S303, obtaining food information according to the picture.

[0096] It can be understood that the camera module can capture pictures reflecting the shape, size, color, surface texture and other characteristics of the food. The camera module is communicated with the memory and the processor to send the picture to the processor for processing or save it to the memory.

[0097] The processor can compare according to the above features and match the most suitable food information. Optionally, the data based on the matching can be stored in the memory, or the processor can upload the above picture information to the server, compare it through the server, and then obtain the comparison result of the server, which is more accurate.

[0098] Of course, the processor can also calculate based on the image to obtain the volume information of the food. Specifically, the processor can identify the area occupied by the food in the plane perpendicular to the optical axis of the camera assembly, and match the control parameters according to the area. The length of the food (i.e., the size parallel to the optical axis) can also be obtained through depth of field information, and the approximate volume parameters can be calculated.

[0099] In this embodiment of the present application, the air fryer can intelligently and actively identify food information, and match corresponding control parameters according to the food information, thereby reducing user operations and improving convenience.

[0100] Reference Figure 5 In another optional embodiment, the air fryer further includes an input module, and the step of obtaining the food information in the cooking cavity includes:

[0101] S301', obtaining a cooking instruction triggered by an input module, wherein the cooking instruction includes food information.

[0102] In this embodiment, the food information is input by the user. The input module includes a plurality of buttons or a touch screen, wherein the plurality of buttons correspond to the plurality of food ingredients one by one or the plurality of touch areas of a certain interface of the display screen correspond to the plurality of food ingredients one by one, and the user can interact with the buttons or touch areas, such as pressing or touching, to input the corresponding food information.

[0103] It is understandable that the user can input one or more of the type information and the volume information. Optionally, the user can input only the information of one ingredient or input the information of multiple ingredients at the same time. For example, as described in the above embodiment, the ingredients for stewing soup include main ingredients and auxiliary ingredients. The user can input only the main ingredient or input both the main ingredient and the auxiliary ingredients.

[0104] In this embodiment, the user inputs the food information, so that the acquisition of food information is more accurate and reliable.

[0105] Of course, in some embodiments, a method of acquiring food information by combining camera module recognition and input module input can also be used. For example, the volume information of the food can be acquired through the camera module, and the type information of the food can be acquired through the user's input. In this way, on the one hand, the camera module recognizes the volume information to make up for the defect that it is difficult for the user to judge the volume of the food, and on the other hand, the input module obtains the type information of the food to ensure the accuracy of the information.

[0106] Optionally, the cooking instruction also includes taste information, and the taste information matches the preset time.

[0107] Specifically, the length of the preset time is closely related to the taste of the food. It can be understood that the longer the food is processed, the softer the food tastes, and vice versa. Therefore, the air fryer can provide at least two preset times, and the user can input at least two taste information through buttons or touch screens, and at least two taste information correspond to at least two preset times. For example, the user can input one of the three taste information of "chewy, moderate, soft", corresponding to one of the three preset times of "40min (minutes), 60min, 90min".

[0108] Alternatively, the user may directly input the preset time information through the input module.

[0109] In this way, the air fryer can cook food that suits the user's taste, enrich the functions of the air fryer, and thus improve user experience and product competitiveness.

[0110] In an optional embodiment, the hot air device includes a fan and a heating element, the heating element is used to dissipate heat, and the fan is used to blow high-temperature air to move. The operating parameters include a first speed and a second speed corresponding to the fan, and a first heating power and a second heating power corresponding to the heating element;

[0111] Please refer back to Figure 2 In the boiling step, the fan operates at a first speed to blow the air in the cooking cavity at a first wind speed V1, and the heating element operates at a first heating power to heat the air in the cooking cavity to a first temperature t1;

[0112] In the stewing step, the fan operates at a second speed to blow the air in the cooking cavity at a second wind speed V1, and the heating element operates at a second heating power to maintain the air in the cooking cavity at a second temperature t2;

[0113] Among them, the first rotation speed is greater than the second rotation speed, and the first heating power is greater than the second heating power.

[0114] It can be understood that the greater the heating power of the heating element, the more heat is dissipated, and the temperature is higher under the premise of a certain air volume; for the same fan, the greater the fan speed, the greater the air flow speed, that is, the wind speed, will be.

[0115] In this embodiment, the first rotation speed is greater than the second rotation speed, and the first heating power is greater than the second heating power, that is, in the boiling step, the air in the cooking cavity moves at a higher temperature and a higher speed, so that the liquid in the cooking cavity boils quickly. A high-speed fan will cause the water in the inner pot to lose quickly, which is easy to cause dry burning, which is not conducive to stewing soup. Therefore, in the stewing step, the air in the cooking cavity moves at a lower temperature and a lower speed, so that the liquid in the cooking cavity is maintained at a preset temperature below the boiling temperature, reducing water loss, continuously heating the food, and is conducive to the full dissolution of flavor and nutrients.

[0116] Exemplarily, under standard atmospheric pressure, when the liquid in the inner pot of the cooking cavity is water, the boiling temperature of water is 100°C, the first temperature t1 satisfies the relationship 200°C≤t1≤300°C, the first wind speed V1 satisfies 2m / s≤V1≤9m / s, and the second temperature t2 satisfies the relationship 100°C≤t2≤150°C, and the second wind speed V2 is approximately 0.1m / s≤V2≤1.5m / s.

[0117] In the boiling step, the first rotation speed and the first heating power are both close to the set maximum values ​​to further accelerate the boiling of the liquid in the cooking cavity.

[0118] In the stewing step, the second rotation speed includes multiple gears, and the second heating power also includes multiple gears. For different ingredients, different gears of second rotation speed and different gears of second heating power can be used for cooking to give full play to the characteristics of the ingredients.

[0119] Of course, the first speed and the first heating power may also include multiple gears to cook according to the characteristics of the food. Among them, the multiple gears of the first speed, the second speed, the first heating power and the second heating power may be steplessly adjusted or stepped, which is not limited in this embodiment.

[0120] Specifically, after the type information of the food is identified, the memory is preset with the correspondence between the type information of the food and the water content and / or fat content, and the first speed, the second speed, the first heating power and the second heating power can be confirmed according to the correspondence between the water content and / or fat content. Among them, as a possible correspondence, the magnitude of the first speed, the second speed, the first heating power and the second heating power is positively correlated with the water content or the fat content, that is, the higher the water content or the fat content, the greater the first speed, the second speed, the first heating power and the second heating power. If the food information includes volume information, the magnitude of the first speed, the second speed, the first heating power and the second heating power is positively correlated with the volume, that is, the larger the volume, the greater the first speed, the second speed, the first heating power and the second heating power.

[0121] In the related art, when stewing soup, the air fryer mostly cooks through the top heating tube and the fan with high wind speed. The top heating tube and the fan cause obvious loss of heat transferred to the bottom of the pot, resulting in temperature stratification, and it takes a long time for the water in the cavity to boil.

[0122] In an optional embodiment of the present application, the hot air device includes a first heating element located at the top of the cooking cavity and a second heating element located at the bottom of the cooking cavity. During the heating operation, the first heating element and the second heating element are controlled to generate heat at the same time to make the temperature at the top and bottom of the cooking cavity more uniform, thereby shortening the time required for the water in the cavity to boil.

[0123] Among them, the heating power of the first heating element is greater than the heating power of the second heating element. Exemplarily, the rated power of the first heating element is 100w, the rated power of the second heating element is 40w, and the first heating element and the second heating element are controlled by different signals. For the convenience of description, the heating power of the first heating element is defined as heating power A, and the heating power of the second heating element is defined as heating power B. In the boiling step, the heating power A is 80w, which is 80% of the rated power, and the heating power B is 20w, which is 50% of the rated power. The first heating power is the sum of the two, that is, 100w; in the stewing step, the heating power A is 50w, which is 50% of the rated power, and the heating power B is 10w, which is 25% of the rated power. The second heating power is the sum of the two, that is, 60w. Obviously, the first heating element and the second heating element are controlled by different signals, and it is ensured that the heating power of the boiling step is greater than the heating power of the stewing step.

[0124] The signals for controlling the first heating element and the second heating element may be pulse signals. It is understandable that the duty cycles of the two pulse signals may be different.

[0125] Combination Figure 6In an optional embodiment of the present application, the air fryer further comprises a temperature sensor for detecting the temperature of the liquid in the cooking cavity, and the boiling step comprises:

[0126] S10, obtaining the temperature of the liquid in the cooking cavity in real time through a temperature sensor;

[0127] S30, controlling the hot air device to operate in a first operating mode so that the temperature of the liquid in the cooking cavity reaches a boiling temperature.

[0128] In this embodiment, in order to avoid the interference of hot air, the temperature sensor probe is inserted into the liquid in the cooking chamber, and the temperature sensor is connected to the processor for real-time feedback of the temperature of the liquid. In the first working condition of the hot air device, the temperature of the liquid continues to rise, and when the temperature of the liquid is equal to the boiling temperature, it is determined that the liquid is boiling, and the hot air device is controlled to operate in the second working condition.

[0129] Of course, in the second working condition, the processor controls the hot air device according to the real-time feedback of the temperature sensor so that the temperature of the liquid in the cooking cavity is maintained at a preset temperature.

[0130] It is understandable that the boiling temperatures of liquids, such as water, are different in areas at different altitudes and latitudes. As an optional solution, when the air fryer is sent to a destination, the boiling temperature is set in advance according to the destination information to meet the normal use requirements at the destination.

[0131] Of course, the present application also proposes another feasible implementation method, in which the cooking cavity is provided with an exhaust hole, and the boiling of the liquid will generate a large amount of steam, which will be discharged through the exhaust hole. By checking the humidity or air pressure at the exhaust hole and other information, it is determined whether the liquid is boiling. For example, the humidity at the exhaust hole is obtained by a hygrometer, and if the humidity is greater than a preset value, it is determined that the liquid is boiling. In this way, it is not necessary to judge whether the liquid is boiling based on the temperature, and the applicability of the air fryer is more extensive.

[0132] Furthermore, a temperature sensor and a hygrometer, a barometer, etc. may be used for combined detection. For example, when the temperature of the liquid reaches the boiling temperature and the value of the hygrometer and / or the barometer exceeds a preset value, the liquid is judged to be boiling, and the result is more accurate and reliable.

[0133] In a third aspect of the embodiment of the present application, an air fryer is further provided, comprising:

[0134] a housing defining a cooking cavity;

[0135] A hot air device for heating the liquid in the cooking cavity;

[0136] A control device controls the hot air device to operate in a first operating mode to heat the liquid in the cooking cavity to boiling, and controls the hot air device to operate in a second operating mode to maintain the liquid in the cooking cavity in a preset temperature range for a preset time, wherein the value of the preset temperature range is lower than the boiling temperature of the liquid.

[0137] Optionally, the hot air device includes a first heating element located at the top of the cooking cavity and a second heating element located at the bottom of the cooking cavity, and the heating power of the first heating element is greater than the heating power of the second heating element. During the heating operation, the first heating element and the second heating element are controlled to heat simultaneously, so that the temperature at the top and bottom of the cooking cavity is more uniform, and the time required for the water in the cavity to boil is shortened.

[0138] The heating power of the first heating element is greater than the heating power of the second heating element. The first heating element and the second heating element are controlled by different signals, so that the modulation of the heating power is more flexible and changeable.

[0139] Furthermore, the air fryer also includes a temperature sensor for detecting the temperature of the liquid in the cooking cavity. The control device obtains the temperature of the liquid in the cooking cavity through the temperature sensor, and controls the hot air device to operate in a first operating condition so that the temperature of the liquid in the cooking cavity reaches a boiling temperature.

[0140] In a fourth aspect, an embodiment of the present application further provides a computer storage medium, on which an executable computer program is stored. When the executable computer program is run, a cooking method as in any of the above embodiments is implemented.

[0141] In the embodiments of the cooking appliance and computer-readable medium of the present invention, all technical features of the above-mentioned cooking control method embodiments are included, and the descriptions and explanations are basically the same as those of the above-mentioned cooking control method embodiments, and are not repeated here.
