Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cooking equipment, in particular to an air fryer, a control method and device thereof, and a readable storage medium. BACKGROUND

[0002] In the related art, a cooking process combination of baking, frying and stewing can produce delicious food. Although an air fryer can complete the baking process in the cooking process combination, it cannot meet the requirement of the stewing process, so that the user needs to use an additional stewing pot to complete the entire cooking process. Therefore, there are defects of complicated cooking process and low cooking efficiency.

[0003] Therefore, how to overcome the above technical defects has become a technical problem to be solved. SUMMARY

[0004] The present application aims to at least solve one of the technical problems in the prior art.

[0005] To this end, the first aspect of the present application provides an air fryer.

[0006] The second aspect of the present application provides a control method of an air fryer.

[0007] The third aspect of the present application provides a control device of an air fryer.

[0008] The fourth aspect of the present application provides a control device of an air fryer.

[0009] The fifth aspect of the present application provides a readable storage medium.

[0010] The sixth aspect of the present application provides an air fryer.

[0011] Therefore, the first aspect of the present application provides an air fryer, which comprises a body, a container arranged in the body and enclosing a cooking cavity, a hot air assembly arranged in the body and configured to blow a high-temperature air flow into the cooking cavity, and a water supply assembly arranged in the body and configured to supply water into the cooking cavity.

[0012] The present application defines an air fryer, which comprises a body and a hot air assembly. The body is a main frame structure of the air fryer, and a cooking cavity is formed in the body. The hot air assembly is mounted on the body and can blow a high-temperature air flow into the cooking cavity after being turned on, so as to heat food placed in the cooking cavity by the high-temperature air flow. Specifically, the high-temperature air flow can rapidly heat the surface of the food, so as to obtain food with a crisp taste and a bright color.

[0013] On this basis, the air fryer further comprises a water supply assembly arranged on the body, and the water supply assembly can deliver water into the cooking cavity after being turned on, so that the food cooked by the high-temperature airflow can be soaked and stewed. For example, in the process of cooking meatballs, the surface of the meatball is first heated by the high-temperature airflow output by the hot air assembly to make the surface of the meatball harden rapidly, so as to prevent the meatball from scattering in the subsequent stewing process, and then the water supply assembly is controlled to inject water into the cooking cavity to stew the soup into the meatball, thereby optimizing the taste of the meatball. Thus, the defects of the related art that the cooking process is complicated, the operation is inconvenient, and multiple devices need to work cooperatively are solved. Further, the technical effects of widening the function of the air fryer, improving the practicality and reliability of the air fryer, and simplifying the cooking process are achieved.

[0014] Specifically, after water is injected into the cooking cavity by the water supply assembly, the high-temperature airflow output by the hot air assembly can be used to heat the water to heat the food soaked therein by the high-temperature water. Alternatively, the water supply assembly directly injects high-temperature water into the cooking cavity to heat the food soaked therein by the high-temperature water. Alternatively, a heating structure mounted on the body is used to heat the water in the cooking cavity to heat the food soaked therein by the high-temperature water.

[0015] In addition, the air fryer provided by the present application can further have the following additional technical features:

[0016] In some technical solutions of the present application, the water supply assembly comprises: a liquid storage tank arranged in the body; a water supply pipeline, a first end of the water supply pipeline being in communication with the liquid storage tank, and a second end of the water supply pipeline being in communication with the cooking cavity; and a pump body arranged in the water supply pipeline.

[0017] In this technical solution, the structure of the water supply assembly is limited. Specifically, the water supply assembly comprises a liquid storage tank, a water supply pipeline, and a pump body. The liquid storage tank is arranged in the body and is used to store water required for cooking. The first end of the water supply pipeline is in communication with the liquid storage tank, and the second end of the water supply pipeline is in communication with the cooking cavity. The pump body is mounted on the water supply pipeline, and the water in the liquid storage tank is pumped to the cooking cavity by the pump body after the pump body is turned on, so as to complete the water adding operation.

[0018] By arranging the liquid storage tank, the air fryer itself has the ability to store water, so that the air fryer can be used independently without an external water source, thereby improving the practicality and convenience of the air fryer. By arranging the water supply pipeline and the pump body, automatic water replenishment is achieved, which eliminates the complicated operation of manually adding water to the cooking cavity, thereby achieving the technical effects of improving the automation and intelligence of the air fryer and improving the user experience.

[0019] In some technical solutions of the present application, the body comprises: a base; and a container arranged on the base and enclosing the cooking cavity.

[0020] In the technical scheme, the base and the container are arranged on the base, and the container is internally enclosed to form a cooking cavity for placing food.

[0021] Specifically, the base is formed with a groove, the shape of the groove is consistent with the outer contour shape of the container, and the container is positioned by being fitted into the groove. When the container needs to be cleaned, the container can be taken out of the groove, thereby providing a convenient condition for cleaning the container.

[0022] In some technical schemes of the present application, optionally, the bottom wall or the side wall of the container comprises a water inlet hole, a water supply pipeline is arranged on the base, a second end of the water supply pipeline is connected to the water inlet hole, and the air fryer further comprises a one-way valve arranged in the water inlet hole, the one-way valve being one-way conducted in the direction from the outside of the container to the inside of the container.

[0023] In the technical scheme, the bottom wall or the side wall of the container is provided with a water inlet hole, the water inlet hole longitudinally penetrates the bottom wall or the side wall of the container. On this basis, the second end of the water supply pipeline is connected to the water inlet hole, and after the container is turned into the base, the water inlet hole is connected to the second end of the water supply pipeline, and the pump body can pump the water in the liquid storage tank into the cooking cavity through the water supply pipeline. Correspondingly, the container is removed to disconnect the water inlet hole and the water supply pipeline, so as to facilitate cleaning of the container.

[0024] On this basis, a one-way valve is further installed at the water inlet hole, the one-way valve is embedded in the water inlet hole, and the one-way valve is one-way conducted in the direction from the outside of the container to the inside of the container. When water is injected into the cooking cavity, the water in the water supply pipeline flows into the cooking cavity under the drive of the water pump to stew the food by high-temperature water soaking the food. After the stewing is completed, the container is removed from the base, and because the one-way valve is one-way conducted from the outside to the inside, the one-way valve can block the water inlet hole to prevent the water in the container from leaking from the water inlet hole, thereby meeting the water supply requirement while retaining the inherent function of the container, and further achieving the technical effects of improving the practicability and reliability of the air fryer.

[0025] In some technical schemes of the present application, optionally, the air fryer further comprises a sealing member connected to the second end of the water supply pipeline for sealing the water supply pipeline and the one-way valve.

[0026] In the technical scheme, the air fryer further comprises a sealing member, the sealing member is sleeved on the second end of the water supply pipeline, and after the container is fitted into the base, the sealing member abuts against the inner wall of the through hole and the bottom surface of the one-way valve, thereby sealing the gap between the through hole and the water supply pipeline and the gap between the water supply pipeline and the one-way valve. Further, the technical effects of improving the sealing performance of the air fryer, preventing water from leaking in and out of the container, protecting the air fryer from being eroded by water, and improving the safety and reliability of the air fryer are achieved.

[0027] Specifically, the sealing member is a rubber plug, and a through hole of the single-way valve and a second end of the water supply pipeline are formed in the rubber plug to ensure the water supply process is not affected. After the container is loaded into the base, the container presses the sealing member to fill the gap between the through hole and the water supply pipeline and the gap between the water supply pipeline and the single-way valve through the deformation of the sealing member.

[0028] In some technical solutions of the present application, the body further comprises a cover body connected with the base, and the cover body covers the container, the hot air assembly and the liquid storage tank are arranged on the cover body.

[0029] In this technical solution, the body further comprises a cover body connected with the base, and the cover body covers the opening at the top of the container after the assembly of the cover body. The hot air assembly is mounted on the cover body so as to arrange the hot air assembly above the container, and the high-temperature gas flow is blown downward to the cooking cavity through the hot air assembly on the cover body during the cooking process.

[0030] In some technical solutions of the present application, the water supply pipeline comprises a first section arranged in the base, a first end of the first section being connected with the liquid storage tank, and a second section arranged in the cover body, a first end of the second section being connected with a second end of the first section, and a second end of the second section being arranged opposite to the opening of the container.

[0031] In this technical solution, the water supply assembly supplies water to the container through the opening at the top of the container. Specifically, the water supply pipeline comprises a first section arranged in the base, a first end of the first section being connected with the liquid storage tank, and a second section arranged in the cover body, a first end of the second section being connected with a second end of the first section, and a second end of the second section being arranged opposite to the opening of the container. After the assembly of the cover body, the second end of the first section is connected with the first end of the second section, and the water supply pipeline can supply water to the opening of the container. When the cover body is disassembled, the second end of the first section is disconnected from the first end of the second section, so as to access the food and the container.

[0032] By arranging the above opening water supply structure, the modification of the container can be avoided, the influence of the water supply assembly on the inherent functions of the container can be reduced, and the risk of water leakage between the container and the water supply assembly can be eliminated, so as to realize the technical effects of optimizing the structure layout of the water supply assembly and improving the safety and reliability of the air fryer.

[0033] Specifically, the second section and the hot air assembly share a set of heating structures. Taking the example of the hot air assembly heating the airflow through a heating tube, the second section is arranged opposite to the heating tube, and the heating tube can heat the liquid in the second section to obtain high-temperature water. The high-temperature water in the second section is injected into the cooking cavity, which can meet the high-temperature cooking demand of the food. Then, the hot air assembly can continuously input high-temperature airflow into the cooking cavity to maintain the temperature of the water, thereby prolonging the stewing time. This structural layout can reduce the structural complexity of the air fryer and reduce the cost of the air fryer while taking into account the water supply function and the stewing function.

[0034] In some technical solutions of the present application, the air fryer further comprises a heating element arranged in the body for heating the container.

[0035] In this technical solution, the air fryer further comprises a heating element arranged on the body, and the heating element can heat the container in the body. During the high-temperature stewing process, the water supply assembly injects water into the container, and the heating element heats the container. The heat is transferred to the water inside the container through the container to increase the temperature of the water, thereby high-temperature stewing the food soaked in the water through the high-temperature water to obtain food with crisp skin and good flavor. In this way, the function of the air fryer is expanded, the cooking process of specific food is simplified, and the quality of the obtained food is improved.

[0036] Specifically, the electric heating element can be selected as the heating element, which is installed on the base and located below the container. After the container is installed, the bottom wall or the side wall of the container is in contact with the electric heating element. After being powered on, the electric heating element generates heat and transfers the heat to the container through contact, so that the container is heated to meet the stewing demand through the high-temperature container. The electromagnetic coil can also be selected as the heating element, which is arranged in the base and also located below the container. At the same time, the container is formed by a magnetic conductive material. After the electromagnetic coil is powered on, a heating electromagnetic field is generated. The container absorbs energy and heats up in the heating electromagnetic field to heat the water and food in the cooking cavity through the high-temperature container, thereby meeting the stewing demand. In this regard, the present application does not rigidly limit the specific structure of the heating element, as long as it meets the heating demand of the water in the container.

[0037] In some technical solutions of the present application, the air fryer further comprises a sensor for measuring the temperature rise rate in the cooking cavity when the hot air assembly is working.

[0038] In some technical solutions of the present application, the air fryer further comprises:

[0039] The controller is connected with the sensor, the heating element and the water supply assembly. The controller is used to control the water supply amount of the water supply assembly according to the temperature rise rate, and the controller is also used to control the heating time of the heating element according to the temperature rise rate.

[0040] The water supply amount and the temperature rise rate satisfy the following relationship:

[0041] m = 0.8 * m1 * k1 / k;

[0042] The heating duration and the temperature rise rate satisfy the following relationship:

[0043] t = 1.1 * t1 * k1 / k;

[0044] m is the water supply amount, m1 is the full-load water supply amount of the cooking cavity in a full-load state, k is the temperature rise rate, k1 is the full-load temperature rise rate of the cooking cavity in a full-load state, t is the heating duration, and t1 is the full-load heating duration of the cooking cavity in a full-load state.

[0045] In the technical scheme, the air fryer further comprises a sensor and a controller, the sensor is installed on the cover body and can contact the gas in the cooking cavity after the cover body is closed, the controller is arranged on the base or the cover body, and the controller is connected with the sensor, the heating component, and the water supply assembly and is used for controlling the heating component and the water supply assembly to work.

[0046] Specifically, the baking temperature rise rate k = ΔT / Δt, ΔT is a temperature change amount, and Δt is a baking duration.

[0047] When the maximum amount of food is in the pot body, the baking temperature rise rate is k1, and the water addition amount is m1, wherein m1 is obtained according to experimental tests on the size of the pot body and the power of the heating tube of the hot air assembly.

[0048] The stewing water addition amount m = 0.8 * m1 * k1 / k, wherein 0.8 is a water addition correction coefficient.

[0049] The stewing time t = 1.1 * t1 * k1 / k.

[0050] When the maximum amount of food is in the pot body, the stewing time is t1, wherein t1 is obtained according to experimental tests on the size of the pot body and the power of the bottom heating system, and 1.1 is a stewing time correction coefficient.

[0051] The second aspect of the present application provides a control method of an air fryer, which is used for controlling the air fryer in any of the above technical solutions to work, and the control method comprises the following steps:

[0052] acquire a cooking instruction;

[0053] control the hot air assembly and the water supply assembly to work in sequence according to the cooking instruction.

[0054] The technical solution defines a control method for controlling the air fryer in any of the above technical solutions. Wherein the air fryer comprises a body and a hot air assembly, the body is the main frame structure of the air fryer, wherein the body is formed with a cooking cavity. The hot air assembly is installed on the body, and the hot air assembly can blow high-temperature airflow into the cooking cavity after being turned on, so as to heat the food placed in the cooking cavity by the high-temperature airflow. Specifically, the high-temperature airflow can rapidly heat the surface of the food, so as to obtain food with crisp taste and bright color.

[0055] The air fryer further comprises a water supply assembly, which is arranged on the body. After the water supply assembly is turned on, the water supply assembly can deliver water into the cooking cavity, so that the food cooked by the high-temperature airflow can be soaked and stewed.

[0056] On this basis, after the air fryer is turned on, a cooking instruction is first acquired. The cooking instruction can be generated by a user terminal or automatically generated after the user touches the control panel of the air fryer. After the cooking instruction is acquired, the hot air assembly is first controlled to work according to the cooking instruction, so as to heat the cooking cavity by means of the high-temperature airflow generated by the hot air assembly. After the hot air heating requirement is met, the hot air assembly is turned off and the water supply assembly is controlled to supply water into the cooking cavity, so as to automatically add water required for stewing.

[0057] For example, in the process of cooking meatballs, the surface of the meatballs is first heated by the high-temperature airflow output by the hot air assembly, so that the surface of the meatballs rapidly hardens, so as to prevent the meatballs from scattering during the subsequent stewing process. Then, the water supply assembly is controlled to inject water into the cooking cavity, so as to stew the soup into the meatballs and optimize the taste of the meatballs. Thus, the defects of complex cooking process, inconvenient operation and the need for the cooperation of multiple devices in the related art are solved. Further, the technical effects of widening the function of the air fryer, improving the practicality and reliability of the air fryer, and simplifying the cooking process are achieved.

[0058] During the stewing process, the air fryer can heat the water in the cooking cavity by means of the high-temperature airflow generated by the hot air assembly, and can also directly heat the cooking cavity by means of the heating element.

[0059] In some technical solutions of the present application, the step of controlling the hot air assembly and the water supply assembly to work in sequence according to the cooking instruction comprises:

[0060] determining a target parameter according to the cooking instruction, the target parameter comprising a first target time length;

[0061] controlling the hot air assembly to be turned on;

[0062] After the hot air assembly operates for the first target duration, the hot air assembly is turned off and the water supply assembly is controlled to work.

[0063] In the technical solution, the cooking instruction contains the kind information and the quality information of the food, wherein different kinds of food correspond to different hot air heating durations under the same unit weight, and on this basis, the greater the total weight of the food is, the longer the required hot air heating duration is. In this regard, after the cooking instruction is obtained, the corresponding first target duration is determined according to the cooking instruction. Then, the hot air assembly is controlled to be turned on and start timing, and when the working duration of the hot air assembly is greater than the first target duration, the hot air assembly is turned off and the water supply assembly is controlled to be turned on.

[0064] The control method can control the hot air assembly to automatically start and stop according to the cooking instruction, thereby on the one hand, the complicated operation of manual intervention control is avoided, and on the other hand, the working duration of the hot air assembly can meet the baking heating requirement of the food in the cooking cavity, so that the food can be fully heated and then enter the stewing stage. Therefore, the working process of the air fryer is optimized, the automation degree and the intelligent degree of the air fryer are improved, and the technical effect of improving the quality of the finally obtained food is achieved.

[0065] In some technical solutions of the present application, optionally, the target parameter further includes a target water supply amount, and the step of controlling the water supply assembly to work includes:

[0066] The water supply assembly is turned on, and the current water amount in the cooking cavity is obtained;

[0067] Based on that the current water amount reaches the target water supply amount, the water supply assembly is controlled to be turned off.

[0068] In the technical solution, the cooking instruction contains the kind information and the quality information of the food, wherein different kinds of food correspond to different water amounts under the same unit weight, and on this basis, the greater the total weight of the food is, the greater the required water amount is. In this regard, after the cooking instruction is obtained, the corresponding target water supply amount is determined according to the cooking instruction, and then when the water supply assembly is controlled to be turned on, the current water amount in the cooking cavity is detected by the water amount detector arranged in the cooking cavity. Since the water supply assembly continuously supplies water into the cooking cavity, the current water amount in the cooking cavity gradually increases. When it is judged that the current water amount reaches the target water supply amount, the water supply assembly is controlled to be turned off, so as to complete the automatic water supply operation.

[0069] The control method can control the water supply assembly to automatically start and stop according to the cooking instruction, thereby on the one hand, the complicated operation of manual intervention control is avoided, and on the other hand, the water supply amount of the water supply assembly can meet the stewing requirement of the food in the cooking cavity. Therefore, the working process of the air fryer is optimized, the automation degree and the intelligent degree of the air fryer are improved, and the technical effect of improving the quality of the finally obtained food is achieved.

[0070] In some embodiments of the present application, the air fryer further comprises a sensor, and the step of controlling the water supply assembly to work comprises:

[0071] The temperature rise rate of the cooking cavity during the operation of the hot air assembly is obtained by the sensor;

[0072] The second target duration is determined according to the temperature rise rate;

[0073] The water supply assembly is controlled to operate for the second target duration.

[0074] In this technical solution, the air fryer further comprises a sensor, which is arranged on the body and is used to sense the temperature rise rate of the cooking cavity during the operation of the hot air assembly. In this regard, during the process of controlling the hot air assembly to operate for the first target duration, the temperature rise rate of the cooking cavity during this process is obtained by the sensor, and then the corresponding second target duration is determined according to the temperature rise rate, wherein the amount of food placed in the cooking cavity is negatively correlated with the temperature rise rate, and the determined second target duration corresponds to the amount of food. Finally, the water supply assembly is controlled to work for the second target duration to ensure that the amount of water provided by the water supply assembly can meet the stewing demand of the food.

[0075] This control method can automatically determine the amount of food in the cooking cavity according to the temperature rise rate sensed by the sensor, and automatically generate the water supply duration required by the water supply assembly according to the actual amount, so as to control the water supply assembly to automatically start and stop, thereby on the one hand, the complicated operation of manual intervention control is avoided, and on the other hand, it is ensured that the water supply amount of the water supply assembly can meet the stewing demand of the food in the cooking cavity. Further, the technical effects of optimizing the working process of the air fryer, improving the automation and intelligence of the air fryer, and improving the quality of the final food are achieved.

[0076] In some embodiments of the present application, the air fryer further comprises a heating element, and the control method further comprises: controlling the heating element to heat the cooking cavity.

[0077] In this technical solution, the air fryer further comprises a heating element, which is arranged on the body, and after the heating element is turned on, the heating element can heat the cooking cavity to increase the temperature of the water and the food in the cooking cavity. On this basis, after the water supply assembly completes the automatic water supply, the heating element is turned on to heat the water soaking the food by the heating element to perform stewing.

[0078] Specifically, the stewing duration can be determined according to the cooking instruction, and the stewing duration can also be derived according to the temperature rise rate sensed by the sensor. After it is determined that the working duration of the heating element meets the stewing demand, the heating element is turned off to complete the entire cooking process.

[0080] an acquisition module configured to acquire a cooking instruction;

[0081] a control module configured to control the hot air assembly and the water supply assembly to work in sequence according to the cooking instruction.

[0082] The technical solution defines a control device for controlling the air fryer in any of the above technical solutions. The air fryer includes a body and a hot air assembly. The body is the main frame structure of the air fryer, and a cooking cavity is formed in the body. The hot air assembly is installed on the body and can blow a high-temperature air flow into the cooking cavity after being turned on to heat the food placed in the cooking cavity by the high-temperature air flow. Specifically, the high-temperature air flow can rapidly heat the surface of the food to make the food have a crisp taste and a shiny color.

[0083] The air fryer further includes a water supply assembly arranged on the body. The water supply assembly can deliver water into the cooking cavity after being turned on, so that the food cooked by the high-temperature air flow can be soaked and stewed.

[0084] On this basis, the control device includes an acquisition module and a control module. After the air fryer is turned on, the acquisition module first acquires a cooking instruction. The cooking instruction can be generated by a user terminal or automatically generated after the user touches the control panel of the air fryer. After the cooking instruction is acquired, the control module controls the hot air assembly to work according to the cooking instruction to heat the cooking cavity by means of the high-temperature air flow generated by the hot air assembly. After the hot air heating requirement is met, the hot air assembly is turned off and the water supply assembly is controlled to supply water into the cooking cavity to automatically add water required for stewing.

[0085] For example, in the process of cooking meatballs, the surface of the meatballs is first heated by the high-temperature air flow output by the hot air assembly to rapidly harden the surface of the meatballs, so as to prevent the meatballs from scattering during the subsequent stewing process. Then, the water supply assembly is controlled to inject water into the cooking cavity to stew the soup into the meatballs, thereby optimizing the taste of the meatballs. Thus, the defects of complex cooking process, inconvenient operation, and the need for multiple devices to work together in the related art are solved. Further, the technical effects of widening the function of the air fryer, improving the practicality and reliability of the air fryer, and simplifying the cooking process are achieved.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0113] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the scope of protection of the present application is not limited by the specific embodiments disclosed below.

[0114] The following refers to Figures 1 to 16 The air fryer and the control method, control device and readable storage medium thereof according to some embodiments of the present application are described.

[0115] As Figure 1 and Figure 2 shown, one embodiment of the present application proposes an air fryer 100, which comprises: a body 110; a container 120 provided on the body 110, the container 120 enclosing a cooking cavity 1102; a hot air assembly 130 provided on the body 110, for blowing high-temperature airflow into the cooking cavity 1102; and a water supply assembly 140 provided on the body 110, for supplying water into the cooking cavity 1102.

[0116] The present application defines an air fryer 100, which comprises a body 110 and a hot air assembly 130, the body 110 being a main frame structure of the air fryer 100, wherein the body 110 is formed with a cooking cavity 1102. The hot air assembly 130 is mounted on the body 110, and the hot air assembly 130 can blow high-temperature airflow into the cooking cavity 1102 after being turned on, so as to heat the food placed in the cooking cavity 1102 by the high-temperature airflow. Specifically, the high-temperature airflow can rapidly heat the surface of the food, so as to obtain food with a crisp taste and a bright color.

[0117] On this basis, the air fryer 100 further comprises a water supply assembly 140, which is arranged on the body 110 and can deliver water into the cooking cavity 1102 after being turned on, so that the food cooked by the high-temperature airflow can be soaked and stewed. For example, in the process of cooking meatballs, the surface of the meatball is first heated by the high-temperature airflow output by the hot air assembly 130 to make the surface of the meatball harden rapidly, so as to prevent the meatball from scattering in the subsequent stewing process, and then the water supply assembly 140 is controlled to inject water into the cooking cavity 1102 to stew the soup into the meatball, thereby optimizing the taste of the meatball. Thus, the defects of complex cooking process, inconvenient operation and the need for multiple devices to work together in the related art are solved. Further, the technical effects of widening the function of the air fryer 100, improving the practicality and reliability of the air fryer 100, and simplifying the cooking process are achieved.

[0118] Specifically, after water is injected into the cooking cavity 1102 by the water supply assembly 140, the water can be heated by the high-temperature airflow output by the hot air assembly 130 to heat the food soaked therein by high-temperature water. Alternatively, the water supply assembly 140 directly injects high-temperature water into the cooking cavity 1102 to heat the food soaked therein by high-temperature water. Alternatively, the water in the cooking cavity 1102 is heated by a heating structure installed on the body 110 to heat the food soaked therein by high-temperature water.

[0120] In this embodiment, the structure of the water supply assembly 140 is limited. Specifically, the water supply assembly 140 comprises a liquid storage tank 142, a water supply pipeline 144 and a pump body 146, the liquid storage tank 142 is arranged in the body 110 and is used to store water required for cooking, the first end of the water supply pipeline 144 is in communication with the liquid storage tank 142, the second end of the water supply assembly 140 is in communication with the cooking cavity 1102, and the pump body 146 is installed on the water supply pipeline 144. After the pump body 146 is turned on, the water in the liquid storage tank 142 is pumped by the pump body 146 to the cooking cavity 1102 to complete the water adding operation.

[0121] By setting the liquid storage tank 142, the air fryer 100 itself has water storage capacity, so that the air fryer 100 can be used independently without external water source, thereby improving the practicality and convenience of the air fryer 100. By setting the water supply pipeline 144 and the pump body 146, automatic water replenishment is realized, which eliminates the complicated operation of manually adding water to the cooking cavity 1102, thereby realizing the technical effect of improving the automation and intelligent degree of the air fryer 100 and improving the user experience.

[0122] As shown in Figure 7 and Figure 8 , in some embodiments of the present application, the body 110 includes: a base 112; a container 120 arranged on the base 112, the container 120 enclosing a cooking cavity 1102; a cover 114 connected with the base 112 and covering the container 120, the hot air assembly 130 and the liquid storage tank 142 are arranged on the cover 114.

[0123] In this embodiment, the body 110 includes the base 112, the container 120 and the cover 114, the container 120 is arranged on the base 112, the container 120 encloses a cooking cavity 1102 for placing food, the cover 114 is connected with the base 112, and the opening at the top of the container 120 is covered by the cover 114 after the cover 114 is assembled. The hot air assembly 130 is installed on the cover 114, so as to arrange the hot air assembly 130 above the container 120, and blow high-temperature airflow downward to the cooking cavity 1102 through the hot air assembly 130 on the cover 114 during cooking.

[0124] Specifically, a groove is formed on the base 112, the shape of the groove is consistent with the outer contour shape of the container 120, and the container 120 can be positioned by being fitted into the groove. When the container 120 needs to be cleaned, the container 120 can be taken out of the groove, thereby providing a convenient condition for cleaning the container 120.

[0125] As shown in Figure 1 , Figure 2 and Figure 3 , in some embodiments of the present application, the bottom wall or the side wall of the container 120 includes a water inlet hole, the water supply pipeline 144 is arranged on the base 112, the second end of the water supply pipeline 144 is connected with the water inlet hole, and the air fryer 100 further includes: a one-way valve 150 arranged on the water inlet hole, the one-way valve 150 is unidirectional in the direction from the outside of the container 120 to the inside of the container 120.

[0126] In this embodiment, the bottom wall or the side wall of the container 120 is provided with a water inlet hole longitudinally penetrating the bottom wall or the side wall of the container 120. On this basis, the second end of the water supply pipeline 144 is connected with the water inlet hole, and after the container 120 is turned into the base 112, the water inlet hole is connected with the second end of the water supply pipeline 144, and the pump body 146 can pump the water in the liquid storage tank 142 into the cooking cavity 1102 through the water supply pipeline 144. Correspondingly, the container 120 is removed to disconnect the water inlet hole and the water supply pipeline 144, so as to facilitate the cleaning of the container 120.

[0127] On this basis, a one-way valve 150 is also installed at the water inlet hole, the one-way valve 150 is embedded in the water inlet hole, and the one-way valve 150 is unidirectional in the direction from the outside of the container 120 to the inside of the container 120. When water is injected into the cooking cavity 1102, the water in the water supply pipeline 144 drives the one-way valve 150 to open under the drive of the water pump, so as to flow into the cooking cavity 1102, so as to stew the food by high-temperature water soaking the food. After the stewing is completed, the container 120 is removed from the base 112, and because the one-way valve 150 is unidirectional from the outside to the inside, the one-way valve 150 can block the water inlet hole to avoid water leakage from the water inlet hole in the container 120, thereby meeting the water supply demand and retaining the inherent function of the container 120, thereby realizing the technical effects of improving the practicability and reliability of the air fryer 100.

[0128] As shown in Figure 1 , Figure 2 and Figure 3 , in some embodiments of the present application, optionally, the air fryer 100 further comprises a sealing piece 160 connected with the second end of the water supply pipeline 144, for sealing the water supply pipeline 144 and the one-way valve 150.

[0129] In this embodiment, the air fryer 100 further comprises a sealing piece 160 sleeved on the second end of the water supply pipeline 144, and after the container 120 is installed in the base 112, the sealing piece 160 abuts against the inner wall of the through hole and the bottom surface of the one-way valve 150, so as to seal the gap between the through hole and the water supply pipeline 144 by the sealing piece 160, and seal the gap between the water supply pipeline 144 and the one-way valve 150. Further, the technical effects of improving the sealing performance of the air fryer 100, avoiding water leakage from the inside and outside of the container 120, protecting the air fryer 100 from water erosion, and improving the safety and reliability of the air fryer 100 are realized.

[0130] Specifically, the sealing member 160 is a rubber plug, and a through hole is formed in the rubber plug to communicate with the second end of the water supply pipeline 144 and the one-way valve 150, so as to ensure that the water supply process is not affected. After the container 120 is installed in the base 112, the container 120 presses the sealing member 160, so as to fill the gap between the through hole and the water supply pipeline 144 and the gap between the water supply pipeline 144 and the one-way valve 150 through the deformed sealing member 160.

[0131] As shown in Figure 4 , Figure 5 and Figure 6 , in some embodiments of the present application, the water supply pipeline 144 optionally comprises a first section 1442 arranged in the base 112, a first end of the first section 1442 being in communication with the liquid storage tank 142, and a second section 1444 arranged in the cover 114, a first end of the second section 1444 being in communication with a second end of the first section 1442, and a second end of the second section 1444 being arranged opposite to the opening of the container 120.

[0132] In this embodiment, the water supply assembly 140 supplies water into the container 120 through the opening at the top of the container 120. Specifically, the water supply pipeline 144 comprises the first section 1442 arranged in the base 112, a first end of the first section 1442 being connected with the liquid storage tank 142, and the second section 1444 arranged in the cover 114, a first end of the second section 1444 being in communication with a second end of the first section 1442, and a second end of the second section 1444 being arranged opposite to the opening of the container 120. After the installation of the cover 114 is completed, the second end of the first section 1442 is in communication with the first end of the second section 1444, so that the water supply pipeline 144 can supply water into the opening of the container 120. When the cover 114 is removed, the second end of the first section 1442 is disconnected from the first end of the second section 1444, so as to facilitate the access to the food and the container 120.

[0133] By arranging the above opening water supply structure, the modification of the container 120 can be avoided, the influence of the water supply assembly 140 on the inherent functions of the container 120 can be reduced, and the risk of water leakage between the container 120 and the water supply assembly 140 can be eliminated, so as to achieve the technical effects of optimizing the structural layout of the water supply assembly 140 and improving the safety and reliability of the air fryer 100.

[0134] Specifically, the second section 1444 and the hot air assembly 130 share a set of heating structures. Taking the example of the hot air assembly 130 heating the airflow through the heating tube 136, the second section 1444 is arranged opposite to the heating tube 136. The heating tube 136 can heat the liquid in the second section 1444 to obtain high-temperature water. Injecting the high-temperature water in the second section 1444 into the cooking cavity 1102 can meet the high-temperature cooking requirement of the food. Then, the hot air assembly 130 can continuously input high-temperature airflow into the cooking cavity 1102 to maintain the temperature of the water, thereby prolonging the stewing time. This structural layout can reduce the structural complexity of the air fryer 100 and reduce the cost of the air fryer 100 while taking into account the water supply function and the stewing function.

[0135] As shown in Figure 1 and Figure 3 In some embodiments of the present application, the base 112 includes a positioning groove 1122, and the air fryer 100 further includes a handle 122 connected to the container 120 and embedded in the positioning groove 1122.

[0136] In this embodiment, the base 112 is formed with a recess, and the shape of the recess is consistent with the outer contour shape of the container 120. The container 120 can be positioned by being fitted into the recess. When the container 120 needs to be cleaned, the container 120 can be taken out of the recess, thereby providing a convenient condition for cleaning the container 120. Meanwhile, the base 112 is further provided with a positioning groove 1122, which is in communication with the recess and transversely penetrates the side wall of the base 112.

[0137] On this basis, the air fryer 100 further includes a handle 122 connected to the outer wall of the container 120, and the handle 122 is located on the lateral side of the container 120. The shape of the positioning groove 1122 is adapted to the outer contour shape of the handle 122. After the container 120 is fitted into the recess, the handle 122 is embedded in the positioning groove 1122, and the end of the handle 122 is exposed outside the base 112. The user can take out the handle 122 together with the container 120 from the base 112 by lifting the handle 122, thereby providing a convenient condition for the user to disassemble and assemble the container 120. Meanwhile, the positioning groove 1122 can cooperate with the handle 122 to position the container 120, ensuring that the container 120 can be accurately installed at the predetermined position and avoiding the loosening and mispositioning of the container 120 during cooking. Further, the structure can improve the structural stability of the air fryer 100 and provide a convenient condition for the user.

[0138] As shown in Figure 3 and Figure 6 In some embodiments of the present application, the air fryer 100 further includes a heating element 170 arranged in the body 110 and used for heating the container 120.

[0139] In this embodiment, the air fryer 100 further comprises a heating element 170 arranged on the body 110, and the heating element 170 is capable of heating the container 120 in the body 110. During the high-temperature stewing process, the water supply assembly 140 injects water into the container 120, and at the same time, the heating element 170 heats the container 120. The heat is transferred to the water inside the container 120 through the container 120 to increase the temperature of the water, so as to high-temperature stew the food soaked in the water by the high-temperature water, so as to obtain food with crisp skin and good flavor. In turn, the technical effects of widening the function of the air fryer 100, simplifying the cooking process of specific food, and improving the quality of the obtained food are achieved.

[0140] Specifically, the electric heating element can be selected as the heating element 170, which is installed on the base 112 and located below the container 120. After the installation of the container 120, the bottom wall or the side wall of the container 120 is in contact with the electric heating element. After being powered on, the electric heating element generates heat and transmits the heat to the container 120 through contact, so as to heat the container 120, thereby meeting the stewing demand through the high-temperature container 120. The electromagnetic coil can also be selected as the heating element 170, which is arranged in the base 112 and also located below the container 120, and at the same time, the container 120 is formed by a magnetic conductive material. After being powered on, the electromagnetic coil generates a heating electromagnetic field, and the container 120 with magnetic conductivity absorbs energy and heats up in the heating electromagnetic field, so as to heat the water and food in the cooking cavity 1102 through the high-temperature container 120, thereby meeting the stewing demand. In this regard, the specific structure of the heating element 170 is not limited in this application, as long as it meets the heating demand of the water in the container 120.

[0141] As shown in Figure 2 and Figure 5 In some embodiments of the present application, the air fryer 100 further comprises a sensor 180 arranged on the cover 114, and the sensor 180 is used to measure the temperature rise rate in the cooking cavity 1102 when the hot air assembly 130 is working. A controller 182 is connected with the sensor 180, the heating element 170 and the water supply assembly 140, and is used to control the working of the heating element 170 and the water supply assembly 140 according to the temperature rise rate.

[0142] In this embodiment, the air fryer 100 further comprises a sensor 180 and a controller 182, the sensor 180 is mounted on the cover 114 and can be in contact with the gas in the cooking cavity 1102 after the cover 114 is closed, and the controller 182 is arranged on the base 112 or the cover 114, and is connected with the sensor 180, the heating element 170 and the water supply assembly 140, and is used to control the working of the heating element 170 and the water supply assembly 140. During the process of high-temperature airflow frying food, the sensor 180 can detect the temperature rise rate in the cooking cavity 1102, and the controller 182 can correspondingly determine the quality of the food placed in the cooking cavity 1102 according to the temperature rise rate. During the stewing process, the controller 182 can determine the corresponding water amount and stewing temperature according to the previously obtained quality, and then control the water supply assembly 140 to inject sufficient water into the cooking cavity 1102, and control the heating element 170 to keep the water at the stewing temperature. Thus, the automatic stewing of food is completed, and the technical effects of optimizing the structure of the air fryer 100, improving the automation and intelligence of the air fryer 100, and improving the quality of the cooked food are realized.

[0143] As shown in Figure 7 and Figure 8 In some embodiments of the present application, the hot air assembly 130 optionally comprises: a motor 132 arranged on the body 110; a fan blade 134 connected with the output shaft of the motor 132 and facing the cooking cavity 1102; and a heating pipe 136 connected with the body 110 and coiled on the side of the fan blade 134.

[0144] In this embodiment, the hot air assembly 130 comprises the motor 132, the fan blade 134 and the heating pipe 136, the motor 132 is mounted on the body 110, and the fan blade 134 is sleeved on the output shaft of the motor 132 and rotates with the output shaft of the motor 132 when the motor 132 is turned on. The fan blade 134 faces the cooking cavity 1102 below to ensure that the airflow blown by the fan blade 134 can act on the food in the cooking cavity 1102. The heating pipe 136 is arranged opposite to the fan blade 134 and below the fan blade 134, so as to heat the airflow blown by the fan blade 134 through the heating pipe 136, and ensure that the hot air assembly 130 can output high-temperature airflow, so as to quickly heat the surface of the food through the temperature-sensing airflow, and simulate the crisp taste similar to oil frying.

[0145] In some embodiments of the present application, the air fryer 100 further comprises a sensor 180, which is used to measure the temperature rise rate in the cooking cavity 1102 when the hot air assembly 130 is working.

[0146] In some embodiments of the present application, the air fryer 100 further comprises a controller 182 connected with the sensor 180, the heating element 170 and the water supply assembly 140, wherein the controller 182 is configured to control the water supply amount of the water supply assembly 140 according to the temperature rise rate, and the controller 182 is further configured to control the heating time of the heating element 170 according to the temperature rise rate.

[0147] The water supply amount and the temperature rise rate satisfy the following relationship:

[0148] m = 0.8 x m1 x k1 ÷ k;

[0149] The heating time and the temperature rise rate satisfy the following relationship:

[0150] t = 1.1 x t1 x k1 ÷ k;

[0151] m is the water supply amount, m1 is the full-load water supply amount of the cooking cavity 1102 in a full-load state, k is the temperature rise rate, k1 is the full-load temperature rise rate of the cooking cavity 1102 in a full-load state, t is the heating time, and t1 is the full-load heating time of the cooking cavity 1102 in a full-load state.

[0152] In this embodiment, the air fryer 100 further comprises a sensor 180 and a controller 182. The sensor 180 is installed on the cover 114 and can contact the gas in the cooking cavity 1102 after the cover 114 is closed. The controller 182 is arranged on the base 112 or the cover 114 and is connected with the sensor 180, the heating element 170 and the water supply assembly 140, and is configured to control the heating element 170 and the water supply assembly 140 to work. During the process of baking food by high-temperature airflow, the sensor 180 can detect the temperature rise rate in the cooking cavity 1102, and the controller 182 can determine the mass of the food placed in the cooking cavity 1102 according to the temperature rise rate. During the stewing process, the controller 182 can determine the corresponding water amount and stewing temperature according to the mass obtained previously, and then control the water supply assembly 140 to inject sufficient water into the cooking cavity 1102 and control the heating element 170 to keep the water at the stewing temperature. Thus, the automatic stewing of food is completed, and the technical effects of optimizing the structure of the air fryer 100, improving the automation and intelligence of the air fryer 100, and improving the quality of the cooked food are achieved.

[0153] Specifically, the baking temperature rise rate k = ΔT ÷ Δt, ΔT is the temperature change amount, and Δt is the baking time.

[0154] When the maximum amount of food is placed in the container 120, the baking temperature rise rate is k1, and the water amount is m1, wherein m1 is obtained according to the size of the container 120 and the experimental test of the heating tube power of the hot air assembly 130.

[0155] The stewing water adding amount m = 0.8 * m1 * k1 ÷ k, wherein 0.8 is a water adding correction coefficient.

[0156] The stewing time t = 1.1 * t1 * k1 ÷ k.

[0157] When the food in the container 120 reaches the maximum amount, the stewing time is t1, wherein t1 is obtained according to the size of the container 120 and the power of the bottom heating system through experimental tests, and 1.1 is a stewing time correction coefficient.

[0158] As shown in FIG. 9, the working process of the air fryer is as follows: Figure 9

[0159] Step 902, the hot air assembly starts to work.

[0160] Step 904, the controller records the temperature rising rate in the baking temperature rising stage.

[0161] Step 906, the stewing water adding amount and the stewing time are determined according to the temperature rising rate.

[0162] Step 908, it is judged whether the baking temperature rising stage is ended, if the result is yes, step 910 is executed, and if the result is no, step 904 is executed.

[0163] Step 910, the water supply assembly starts to work.

[0164] Step 912, it is judged whether the added water amount reaches the stewing water adding amount, if the result is yes, step 914 is executed, and if the result is no, step 910 is executed.

[0165] Step 914, the water supply assembly stops to work, and the heating element starts to work.

[0166] Step 916, it is judged whether the working time of the heating element reaches the stewing time, if the result is yes, step 918 is executed, and if the result is no, step 914 is executed.

[0167] Step 918, the heating element stops to work.

[0168] Specifically, in step 906, the baking temperature rising rate k = ΔT ÷ Δt, ΔT is the temperature change amount, and Δt is the baking time length.

[0169] When the food in the pot reaches the maximum amount, the baking temperature rising rate is k1, and the water adding amount is m1, wherein m1 is obtained according to the size of the pot and the power of the hot air assembly heating tube through experimental tests.

[0170] The stewing water adding amount m = 0.8 * m1 * k1 ÷ k, wherein 0.8 is a water adding correction coefficient.

[0171] The stewing time t = 1.1 * t1 * k1 ÷ k. ​

[0172] When the maximum amount of food is in the pot body, the stewing time is t1, wherein t1 is obtained according to the size of the pot body and the power of the bottom heating system through experimental testing, and 1.1 is a correction coefficient of the stewing time.

[0173] As shown in Figure 10 An embodiment of the present application provides a control method of an air fryer, which is used for controlling the air fryer in any of the above embodiments to work, and the control method comprises the following steps:

[0174] In step 1002, a cooking instruction is obtained.

[0175] In step 1004, the hot air assembly and the water supply assembly are controlled to work in sequence according to the cooking instruction.

[0176] This embodiment defines a control method for controlling the air fryer in any of the above embodiments. The air fryer comprises a body and a hot air assembly, the body is a main frame structure of the air fryer, and a cooking cavity is formed in the body. The hot air assembly is installed on the body, and the hot air assembly can blow a high-temperature gas flow into the cooking cavity after being turned on, so as to heat the food placed in the cooking cavity by the high-temperature gas flow. Specifically, the high-temperature gas flow can rapidly heat the surface of the food, so as to obtain food with a crisp taste and a bright color.

[0177] The air fryer further comprises a water supply assembly, which is arranged on the body. After the water supply assembly is turned on, the water supply assembly can deliver water into the cooking cavity, so that the food cooked by the high-temperature gas flow can be soaked and stewed.

[0178] On this basis, after the air fryer is turned on, a cooking instruction is first obtained. The cooking instruction can be generated by a user terminal or automatically generated after the user touches the control panel of the air fryer. After the cooking instruction is obtained, the hot air assembly is controlled to work according to the cooking instruction, so as to heat the cooking cavity by means of the high-temperature gas flow generated by the hot air assembly. After the hot air heating demand is met, the hot air assembly is turned off and the water supply assembly is controlled to supply water into the cooking cavity, so as to automatically add water required for stewing.

[0179] For example, in the process of cooking meatballs, the surface of the meatballs is first heated by the high-temperature gas flow output by the hot air assembly, so that the surface of the meatballs is rapidly hardened, so as to prevent the meatballs from scattering in the subsequent stewing process. Then, the water supply assembly is controlled to inject water into the cooking cavity, so as to stew the soup into the meatballs and optimize the taste of the meatballs. Thus, the defects of the related art, such as a complex cooking process, inconvenient operation and the need for the cooperation of multiple devices, are solved. In turn, the technical effects of widening the function of the air fryer, improving the practicality and reliability of the air fryer, and simplifying the cooking process are achieved.

[0180] During the stewing process, the air fryer can heat the water in the cooking cavity by means of the high-temperature airflow generated by the hot air assembly, and can also directly heat the cooking cavity by the heating piece.

[0181] As shown in Figure 11 In some embodiments of the present application, optionally, the step of controlling the hot air assembly and the water supply assembly to work in sequence according to the cooking instruction comprises:

[0182] Step 1102, determining a target parameter according to the cooking instruction, the target parameter comprising a first target time length;

[0183] Step 1104, controlling the hot air assembly to start;

[0184] Step 1106, after the hot air assembly runs for the first target time length, the hot air assembly is turned off and the water supply assembly is controlled to work.

[0185] In this embodiment, the cooking instruction contains the category information and the quality information of the food, wherein different categories of food correspond to different hot air heating time lengths under the same unit weight, and the total weight of the food is greater, the longer the hot air heating time length required. For this, after obtaining the cooking instruction, the corresponding first target time length is determined according to the cooking instruction. Thereafter, the hot air assembly is controlled to start and start timing, and when the working time length of the hot air assembly is greater than the first target time length, the hot air assembly is turned off and the water supply assembly is controlled to start.

[0186] The control method can automatically start and stop the hot air assembly according to the cooking instruction, thereby on the one hand, avoiding the complicated operation of manual intervention control, and on the other hand, ensuring that the working time length of the hot air assembly can meet the baking heating demand of the food in the cooking cavity, and ensuring that the food is heated sufficiently before entering the stewing stage. Further, the working process of the air fryer is optimized, the automation and intelligence of the air fryer are improved, and the technical effect of improving the quality of the final food is achieved.

[0187] As shown in Figure 12 In some embodiments of the present application, optionally, the target parameter further comprises a target water supply amount, and the step of controlling the water supply assembly to work comprises:

[0188] Step 1202, starting the water supply assembly, and obtaining the current water amount in the cooking cavity;

[0189] Step 1204, based on the current water amount reaching the target water supply amount, controlling the water supply assembly to stop.

[0190] In this embodiment, the cooking instruction contains the category information and quality information of the food, wherein different categories of food correspond to different water amounts under the same unit weight, and the greater the total weight of the food, the greater the water amount required. In this regard, after obtaining the cooking instruction, the corresponding target water supply amount is determined according to the cooking instruction, and then after the water supply assembly is controlled to be turned on, the current water amount in the cooking cavity is detected according to the water amount detector arranged in the cooking cavity. Since the water supply assembly continuously supplies water into the cooking cavity, the current water amount in the cooking cavity gradually increases, and when it is judged that the current water amount reaches the target water supply amount, the water supply assembly is controlled to be turned off, so as to complete the automatic water supply operation.

[0191] The control method can control the water supply assembly to automatically start and stop according to the cooking instruction, thereby on the one hand, the complicated operation of manual intervention control is avoided, and on the other hand, it is ensured that the water supply amount of the water supply assembly can meet the stewing demand of the food in the cooking cavity. Further, the working process of the air fryer is optimized, the automation and intelligent degree of the air fryer are improved, and the technical effect of improving the quality of the final food is achieved.

[0192] As shown in Figure 13 In some embodiments of the present application, the air fryer further comprises a sensor, and the step of controlling the water supply assembly to work comprises:

[0193] Step 1302, obtaining the temperature rise rate of the cooking cavity in the working process of the hot air assembly through the sensor;

[0194] Step 1304, determining a second target time according to the temperature rise rate;

[0195] Step 1306, controlling the water supply assembly to run for the second target time.

[0196] In this embodiment, the air fryer further comprises a sensor, the sensor is arranged on the body, and the sensor is used to sense the temperature rise rate of the cooking cavity in the working process of the hot air assembly. In this regard, in the process of controlling the hot air assembly to run for the first target time, the temperature rise rate of the cooking cavity in the process is obtained by the sensor, and then a corresponding second target time is determined according to the temperature rise rate, wherein the amount of food put into the cooking cavity is negatively related to the temperature rise rate, and the determined second target time corresponds to the amount of food. Finally, the water supply assembly is controlled to work for the second target time, so as to ensure that the water amount provided by the water supply assembly can meet the stewing demand of the food.

[0197] The control method can automatically determine the amount of food in the cooking cavity according to the temperature rise rate sensed by the sensor, and automatically generate the water supply time required by the water supply assembly according to the actual amount, to control the automatic start and stop of the water supply assembly, thereby on the one hand, avoiding the complicated operation of manual intervention control, and on the other hand, ensuring that the water supply amount of the water supply assembly can meet the stewing demand of the food in the cooking cavity. Further, the working process of the air fryer is optimized, the automation and intelligence of the air fryer are improved, and the technical effect of improving the quality of the final food is achieved.

[0198] In some embodiments of the present application, optionally, the air fryer further comprises a heating member, and the control method further comprises: controlling the heating member to heat the cooking cavity.

[0199] In this embodiment, the air fryer further comprises a heating member, which is arranged on the body. After the heating member is turned on, it can heat the cooking cavity to increase the temperature of the water and food in the cooking cavity. On this basis, after the water supply assembly completes the automatic water supply, the heating member is turned on to heat the water soaking the food by the heating member to perform stewing.

[0200] Specifically, the stewing time can be determined according to the cooking instruction, and the stewing time can also be obtained according to the temperature rise rate sensed by the sensor. After it is determined that the working time of the heating member meets the stewing demand, the heating member is turned off to complete the entire cooking process.

[0201] As shown in Figure 14 An embodiment of the present application provides a control device 1400 of an air fryer for controlling the air fryer in any of the above embodiments, the control device comprising:

[0202] The acquisition module 1402 is configured to acquire a cooking instruction.

[0203] The control module 1404 is configured to control the hot air assembly and the water supply assembly to work in sequence according to the cooking instruction.

[0204] This embodiment defines a control device 1400 for controlling the air fryer in any of the above embodiments. The air fryer comprises a body and a hot air assembly. The body is the main frame structure of the air fryer, and the cooking cavity is formed in the body. The hot air assembly is installed on the body. After the hot air assembly is turned on, it can blow high-temperature air flow into the cooking cavity to heat the food placed in the cooking cavity by the high-temperature air flow. Specifically, the high-temperature air flow can rapidly heat the surface of the food to obtain food with crisp taste and bright color.

[0205] The air fryer further comprises a water supply assembly arranged on the body. After the water supply assembly is turned on, it can deliver water into the cooking cavity, so that the food cooked by the high-temperature air flow can be soaked and stewed.

[0206] On this basis, the control device includes an acquisition module 1402 and a control module 1404. After the air fryer is turned on, the acquisition module 1402 first acquires a cooking instruction. The cooking instruction can be generated by a user terminal and can also be automatically generated after the user touches the control panel of the air fryer. After the cooking instruction is acquired, the control module 1404 controls the hot air assembly to work according to the cooking instruction, so as to heat the cooking cavity by means of the high-temperature airflow generated by the hot air assembly. After the hot air heating requirement is met, the hot air assembly is turned off and the water supply assembly is controlled to supply water into the cooking cavity, so as to automatically add water required for stewing.

[0207] For example, in the process of cooking meatballs, the surface of the meatballs is first heated by the high-temperature airflow output by the hot air assembly, so that the surface of the meatballs is rapidly hardened to prevent the meatballs from scattering during the subsequent stewing process. Then, the water supply assembly is controlled to inject water into the cooking cavity to stew the soup into the meatballs, thereby optimizing the taste of the meatballs. Thus, the defects of the related art that the cooking process is complicated, inconvenient to operate, and requires the cooperation of multiple devices are solved. Further, the technical effects of widening the function of the air fryer, improving the practicality and reliability of the air fryer, and simplifying the cooking process are achieved.
