Description

Technical Field

[0001] This application relates to the field of air fryer technology, and more specifically, to an air fryer and its control method, control device and readable storage medium. Background Technology

[0002] Air fryers include fan blades. Because of their large diameter and thickness, the fan blades are quite heavy, which increases their inertia. Even after the air fryer's motor is turned off, the fan blades continue to rotate for a longer period due to inertia.

[0003] In this way, the fan blades will continue to rotate after the cover is opened, resulting in non-compliance with safety regulations. Summary of the Invention

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes an air fryer.

[0006] The second aspect of this application proposes an air fryer.

[0007] A third aspect of this application proposes an air fryer.

[0008] The fourth aspect of this application proposes a method for controlling an air fryer.

[0009] The fifth aspect of this application discloses a control device for an air fryer.

[0010] The sixth aspect of this application discloses a control device for an air fryer.

[0011] The seventh aspect of this application proposes a readable storage medium.

[0012] The eighth aspect of this application proposes an air fryer.

[0013] In view of the above, the first aspect of this application proposes an air fryer, comprising: a shell assembly having a cooking cavity within it; fan blades located within the cooking cavity; an electromagnet, the fan blades being magnetically conductive, the electromagnet being used to drive the fan blades to generate heat; and a limiting structure disposed on the shell assembly, the limiting structure including a stop member, the stop member being movable relative to the shell assembly to switch between a first position and a second position; when the stop member is in the first position, the stop member is used to restrict the rotation of the fan blades; when the stop member is in the second position, the stop member releases the restriction on the fan blades, allowing the fan blades to rotate.

[0014] This application provides an air fryer comprising a shell assembly, fan blades, an electric disk, and a limiting structure.

[0015] The limiting structure is located on the housing assembly, which serves as the mounting carrier for the limiting structure and has the function of installing and fixing the limiting structure.

[0016] The housing assembly contains a cooking chamber, and the fan blades are located within the cooking chamber. Food is placed in the cooking chamber and cooked there to meet usage needs such as air-frying, heating, and baking.

[0017] The limiting structure includes a stop that is movable relative to the housing assembly to switch between a first position and a second position.

[0018] When the stop is switched to the first position, the stop can restrict the rotation of the fan blades, and the fan blades can no longer rotate.

[0019] When the stop is switched to the second position, the stop is released from restricting the fan blades, allowing them to rotate. The fan blades can rotate within the cooking chamber to create hot air circulation, thereby achieving the purpose of cooking the food.

[0020] Optionally, the air fryer includes a flip-top air fryer or a drum-type air fryer. Specifically, in a flip-top air fryer, the cooking chamber is closed or opened when the lid is closed or away from the base.

[0021] It is understandable that the fan blades will continue to rotate for a period of time due to inertia after cooking is finished. In other words, there is a possibility that the fan blades will continue to rotate after the lid is opened.

[0022] This application, by setting a limiting structure, allows the stop component of the limiting structure to switch between a first position and a second position according to specific circumstances. When the stop component switches to the first position, it can restrict the rotation of the fan blades, causing them to stop rotating in time, thereby improving the safety and reliability of product use. Specifically, in the event of accidental operation or sudden opening of the air fryer, the stop component can effectively stop the fan blades from rotating, ensuring the safety and reliability of the air fryer. Furthermore, due to the limiting structure, the stop component can effectively cooperate with the fan blades, making the stopping of fan blade rotation not limited by the weight and size of the fan blades, ensuring the effectiveness and feasibility of limiting fan blade rotation. Simultaneously, because of the limiting structure, when the motor switches to a stop position, it can effectively shorten the fan blade rotation time, meeting the requirement of stopping fan blade rotation.

[0023] Furthermore, the fan blades are magnetic components, and the electric magnetic disk drives the fan blades to generate heat. When the electric magnetic disk is energized, it generates an alternating magnetic field. Under the influence of this alternating magnetic field, the magnetically conductive fan blades generate heat. That is, through the interaction between the electric magnetic disk and the magnetically conductive fan blades, the fan blades can rapidly increase in temperature within a short time. Simultaneously, driven by the motor, the fan blades rotate within the cooking cavity, rapidly generating hot air within the cavity.

[0024] Optionally, when the air fryer is powered off, the stop is in the first position. This stop restricts the fan blades from rotating, meaning the fan blades cannot continue to rotate. In this state, even if the air fryer is opened, there will be no safety hazard.

[0025] Optionally, when the air fryer is in standby mode, the stop is in the first position to limit the rotation of the fan blades.

[0026] Optionally, when the cooking cavity is opened during cooking, the stop is in the first position. This stops the fan blade rotation, preventing accidental injury to the user.

[0027] Optionally, when cooking is finished, the stop is in the first position to limit the rotation of the fan blades.

[0028] Optionally, when the cooking cavity is opened within a preset time after cooking is completed, the stop is in the first position to limit the rotation of the fan blades.

[0029] Optionally, when the cooking cavity is closed within a preset time after cooking, the stop is in the second position. At this time, there is no need to control the stop to switch to the first position, and the fan blades can automatically stop rotating. This reduces the number of contacts between the stop and the fan blades, that is, it reduces the number of times the fan blades need to be actively stopped during the lifespan of the air fryer, which helps to extend the service life of the stop and the fan blades.

[0030] Optionally, when the air fryer is in cooking mode, the stop is in the second position. This releases the restriction on the fan blades, allowing them to rotate under the action of the motor to achieve the cooking purpose.

[0031] The air fryer described above according to this application may also have the following additional technical features:

[0032] In some embodiments, optionally, one of the stop and the fan blade has a positioning portion, and when the stop is in a first position, the positioning portion cooperates with the other of the stop and the fan blade, preventing the fan blade from rotating.

[0033] In some embodiments, optionally, when the stop is in the first position, the stop abuts against the fan blade, and when the stop is in the second position, the stop separates from the fan blade.

[0034] In some embodiments, optionally, when the stop is in the first position, the surfaces of the stop and the fan blade that contact each other are respectively referred to as the first mating surface and the second mating surface, and at least one of the first mating surface and the second mating surface has a limiting portion.

[0035] In some embodiments, the stop may optionally be movable along the height direction of the housing assembly.

[0036] In some embodiments, the air fryer may optionally include: a drive member for driving a stop member to move; a protective cover disposed within the cooking cavity, the protective cover and the cavity wall of the cooking cavity enclosing an installation cavity, a fan blade located within the installation cavity, and the protective cover having an outlet that connects the installation cavity and the cooking cavity.

[0038] In some embodiments, the air fryer may optionally include: a motor, the motor and a drive unit being located on the same side of the mounting plate, the motor having a drive shaft passing through the mounting plate and connected to the fan blades.

[0039] In this embodiment, the structure of the air fryer is further defined such that it also includes a motor with a drive shaft that passes through a mounting plate and is connected to fan blades. The motor's operation drives the fan blades to rotate, thereby circulating hot air within the cooking chamber.

[0040] The motor and drive unit are located on the same side of the mounting plate. That is, the motor and drive unit are arranged separately from the electromagnet through the mounting plate. The electromagnet can generate heat when it is working. The mounting plate has the function of reducing the heat transferred to the motor and drive unit, which can ensure the ambient temperature of the motor and drive unit and provide reliable structural support for ensuring the service life of the motor and drive unit.

[0041] Optionally, the housing assembly is provided with an air vent that is connected to the motor and drive unit, and also to the electric disk.

[0045] The housing assembly contains a cooking chamber, and the fan blades are located within the cooking chamber. Food is placed in the cooking chamber and cooked there to meet usage needs such as air-frying, heating, and baking.

[0046] The limiting structure includes a stop that is movable relative to the housing assembly to switch between a first position and a second position.

[0047] When the stop is switched to the first position, the stop can restrict the rotation of the fan blades, and the fan blades can no longer rotate.

[0052] Optionally, when the air fryer is powered off, the stop is in the first position. This stop restricts the fan blades from rotating, meaning the fan blades cannot continue to rotate. In this state, even if the air fryer is opened, there will be no safety hazard.

[0053] Optionally, when the air fryer is in standby mode, the stop is in the first position to limit the rotation of the fan blades.

[0054] Optionally, when the cooking cavity is opened during cooking, the stop is in the first position. This stops the fan blade rotation, preventing accidental injury to the user.

[0055] Optionally, when cooking is finished, the stop is in the first position to limit the rotation of the fan blades.

[0056] Optionally, when the cooking cavity is opened within a preset time after cooking is completed, the stop is in the first position to limit the rotation of the fan blades.

[0057] Optionally, when the cooking cavity is closed within a preset time after cooking, the stop is in the second position. At this time, there is no need to control the stop to switch to the first position, and the fan blades can automatically stop rotating. This reduces the number of contacts between the stop and the fan blades, that is, it reduces the number of times the fan blades need to be actively stopped during the lifespan of the air fryer, which helps to extend the service life of the stop and the fan blades.

[0058] Optionally, when the air fryer is in cooking mode, the stop is in the second position. This releases the restriction on the fan blades, allowing them to rotate under the action of the motor to achieve the cooking purpose.

[0059] In some embodiments, optionally, one of the stop and the fan blade has a positioning portion, and when the stop is in a first position, the positioning portion cooperates with the other of the stop and the fan blade, preventing the fan blade from rotating.

[0062] In some embodiments, the stop may optionally be movable along the height direction of the housing assembly.

[0063] In some embodiments, the housing assembly may optionally include a mounting plate located on the side of the air fryer's drive unit facing the fan blades. The mounting plate includes: an inner cover located between the cooking chamber and the drive unit, with a stop extending through the inner cover and into the cooking chamber; or, a heat insulation sub-plate forming part of the wall of the cooking chamber, with a stop extending through the heat insulation sub-plate and into the cooking chamber; or, an inner cover and a heat insulation sub-plate, the inner cover located between the cooking chamber and the drive unit, the heat insulation sub-plate forming part of the wall of the cooking chamber, the heat insulation sub-plate having a through hole, and the stop extending through the inner cover and the through hole into the cooking chamber.

[0064] A third aspect of this application discloses an air fryer, comprising: a shell assembly having a cooking cavity within it; fan blades located within the cooking cavity; a magnetic disk drive, the fan blades being magnetically conductive, the magnetic disk drive being used to drive the fan blades to generate heat; and a limiting structure disposed on the shell assembly, the limiting structure including a stop member, the stop member being movable relative to the shell assembly to switch between a first position and a second position. When the stop member is in the first position, the stop member is used to restrict the rotation of the fan blades; when the stop member is in the second position, the stop member releases the restriction on the fan blades, allowing the fan blades to rotate. When the air fryer is in a first state, the stop member is in the first position, the first state including a power-off state, a standby state, or a state where the cooking cavity is open during cooking. When the air fryer is in a second state, the stop member is in the first position, or when the air fryer is in a third state, the stop member is in the second position, the second state including a cooking-completed state or a state where the cooking cavity is open within a preset time after cooking, and the third state including a cooking cavity closed within a preset time after cooking or a cooking state.

[0065] This application provides an air fryer comprising a shell assembly, fan blades, an electric disk, and a limiting structure.

[0066] The limiting structure is located on the housing assembly, which serves as the mounting carrier for the limiting structure and has the function of installing and fixing the limiting structure.

[0067] The housing assembly contains a cooking chamber, and the fan blades are located within the cooking chamber. Food is placed in the cooking chamber and cooked there to meet usage needs such as air-frying, heating, and baking.

[0068] The limiting structure includes a stop that is movable relative to the housing assembly to switch between a first position and a second position.

[0069] When the stop is switched to the first position, the stop can restrict the rotation of the fan blades, and the fan blades can no longer rotate.

[0070] When the stop is switched to the second position, the stop is released from restricting the fan blades, allowing them to rotate. The fan blades can rotate within the cooking chamber to create hot air circulation, thereby achieving the purpose of cooking the food.

[0071] Optionally, the air fryer includes a flip-top air fryer or a drum-type air fryer. Specifically, in a flip-top air fryer, the cooking chamber is closed or opened when the lid is closed or away from the base.

[0072] It is understandable that the fan blades will continue to rotate for a period of time due to inertia after cooking is finished. In other words, there is a possibility that the fan blades will continue to rotate after the lid is opened.

[0075] Optionally, when the air fryer is in the first state (e.g., power off state), the stop is in the first position. This stop restricts the fan blades from rotating, meaning the fan blades cannot continue to rotate. In this state, even if the air fryer is opened, there will be no safety hazard.

[0076] Optionally, when the air fryer is in a first state (e.g., standby state), the stop is in a first position to limit the rotation of the fan blades.

[0077] Optionally, when the air fryer is in the first state (e.g., the cooking chamber is open during cooking), the stop is in the first position. This stop restricts the rotation of the fan blades, preventing accidental injury to the user.

[0078] Optionally, when the air fryer is in the second state (e.g., cooking finished state), the stop is in the first position to limit the rotation of the fan blades.

[0079] Optionally, when the air fryer is in the second state (e.g., the cooking chamber is opened after a preset time following cooking), the stop is in the first position to limit the rotation of the fan blades.

[0080] Optionally, when the air fryer is in the third state (e.g., the cooking chamber is closed for a preset time after cooking), the stop is in the second position. At this time, there is no need to control the stop to switch to the first position, and the fan blades can automatically stop rotating. This reduces the number of contacts between the stop and the fan blades, that is, it reduces the number of times the fan blades need to be actively stopped during the air fryer's lifespan, thus extending the service life of the stop and the fan blades.

[0081] Optionally, when the air fryer is in the third state (e.g., cooking state), the stop is in the second position. This releases the restriction on the fan blades, allowing them to rotate under the action of the motor to achieve the cooking purpose.

[0082] In some embodiments, optionally, one of the stop and the fan blade has a positioning portion, and when the stop is in a first position, the positioning portion cooperates with the other of the stop and the fan blade, preventing the fan blade from rotating.

[0083] In some embodiments, optionally, when the stop is in the first position, the stop abuts against the fan blade, and when the stop is in the second position, the stop separates from the fan blade.

[0085] In some embodiments, the stop may optionally be movable along the height direction of the housing assembly.

[0086] In some embodiments, the air fryer may optionally include: a drive member for driving a stop member to move; a protective cover disposed within the cooking cavity, the protective cover and the cavity wall of the cooking cavity enclosing an installation cavity, a fan blade located within the installation cavity, and the protective cover having an outlet that connects the installation cavity and the cooking cavity.

[0087] In some embodiments, the housing assembly may optionally include a mounting plate located on the side of the air fryer's drive unit facing the fan blades. The mounting plate includes: an inner cover located between the cooking chamber and the drive unit, with a stop extending through the inner cover and into the cooking chamber; or, a heat insulation sub-plate forming part of the cavity wall of the cooking chamber, with a stop extending through the heat insulation sub-plate and into the cooking chamber; or, an inner cover and a heat insulation sub-plate, the inner cover located between the cooking chamber and the drive unit, the heat insulation sub-plate having a through hole, a magnetic disk located between the heat insulation sub-plate and the inner cover, the heat insulation sub-plate forming part of the cavity wall of the cooking chamber, and a stop extending through the inner cover and the through hole into the cooking chamber.

[0088] In some embodiments, the air fryer may optionally include: a motor, the motor and a drive unit being located on the same side of the mounting plate, the motor having a drive shaft passing through the mounting plate and connected to the fan blades.

[0089] The fourth aspect of this application discloses a control method for an air fryer. The air fryer includes a shell assembly, fan blades, and a limiting structure. The shell assembly has a cooking cavity, and the fan blades are located within the cooking cavity. The limiting structure is disposed on the shell assembly and includes a stop member. The stop member is movable relative to the shell assembly to switch between a first position and a second position. When the stop member is in the first position, it restricts the rotation of the fan blades. When the stop member is in the second position, it releases the restriction on the fan blades, allowing the fan blades to rotate. The control method for the air fryer includes: determining the working state of the air fryer based on an acquired working signal; and controlling the stop member to switch between the first and second positions based on the working state of the air fryer.

[0090] In the air fryer control method provided in this application, the working state of the air fryer is determined based on the acquired working signal, and the stop member is controlled to switch between a first position and a second position according to the working state of the air fryer. In other words, the working state of the air fryer affects the position of the stop member.

[0091] When the stop is in the first position, it contacts the air fryer's fan blades, preventing them from rotating further and thus stopping them, improving the safety and reliability of the product. Specifically, in case of accidental operation or sudden opening of the air fryer, the stop effectively stops the fan blades, ensuring their continued rotation and guaranteeing the safety and reliability of the air fryer. Furthermore, the ability to switch the stop to the first position allows it to effectively engage with the fan blades, making the stopping of fan blade rotation unrestricted by their weight or size, ensuring the effectiveness and timeliness of the rotation restriction. Simultaneously, the ability to switch the stop to the first position also effectively shortens the fan blade rotation time when the motor switches to a stop position, meeting the requirement for complete fan blade cessation.

[0092] When the stop is in the second position, it releases the restriction on the fan blades, allowing them to rotate. The fan blades can then rotate within the cooking cavity, creating a hot air circulation and thus achieving the purpose of cooking the food.

[0093] In some embodiments, optionally, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: controlling the stop to switch to the second position when the air fryer starts cooking; and controlling the stop to switch to the first position when the air fryer is in a power-off state or the cooking chamber is opened.

[0094] In some embodiments, optionally, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: when the air fryer is in the cooking end state, detecting whether the cooking cavity is opened within a preset time; if the cooking cavity is opened within the preset time, controlling the stop to switch to the first position; if the cooking cavity is not opened within the preset time, controlling the stop to stay in the second position.

[0095] In some embodiments, optionally, the step of controlling the stop to switch to the first position when the cooking cavity is opened within a preset time period specifically includes: controlling the stop to switch to the first position when the cooking cavity is opened within a preset time period.

[0096] In some embodiments, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: when the air fryer is in the cooking end state, controlling the stop to switch to the first position.

[0097] In some embodiments, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: when the air fryer is in standby mode, controlling the stop to switch to the first position.

[0098] The fifth aspect of this application discloses a control device for an air fryer, used to control the air fryer. The air fryer includes a shell assembly, fan blades, and a limiting structure. The shell assembly has a cooking cavity, and the fan blades are located within the cooking cavity. The limiting structure is disposed on the shell assembly and includes a stop member. The stop member is movable relative to the shell assembly to switch between a first position and a second position. When the stop member is in the first position, it restricts the rotation of the fan blades. When the stop member is in the second position, it releases the restriction on the fan blades, allowing the fan blades to rotate. The control device for the air fryer includes: a control module, used to determine the working state of the air fryer based on acquired working signals; and to control the stop member to switch between the first and second positions based on the working state of the air fryer.

[0099] The control device for the air fryer provided in this application includes a control module. The control module determines the operating state of the air fryer based on acquired operating signals, and controls a stop member to switch between a first position and a second position according to the operating state of the air fryer. In other words, the operating state of the air fryer affects the position of the stop member.

[0100] When the stop is in the first position, it contacts the air fryer's fan blades, preventing them from rotating further and thus stopping them, improving the safety and reliability of the product. Specifically, in case of accidental operation or sudden opening of the air fryer, the stop effectively stops the fan blades, ensuring their continued rotation and guaranteeing the safety and reliability of the air fryer. Furthermore, the ability to switch the stop to the first position allows it to effectively engage with the fan blades, making the stopping of fan blade rotation unrestricted by their weight or size, ensuring the effectiveness and timeliness of the rotation restriction. Simultaneously, the ability to switch the stop to the first position also effectively shortens the fan blade rotation time when the motor switches to a stop position, meeting the requirement for complete fan blade cessation.

[0101] When the stop is switched to the second position, the stop releases its restriction on the fan blades, allowing them to rotate. The fan blades can then rotate within the cooking chamber, creating a hot air circulation and thus achieving the purpose of cooking the food.

[0102] In some embodiments, the control module is optionally configured to control the stop to switch to a second position when the air fryer starts cooking, and to control the stop to switch to a first position when the air fryer is powered off or the cooking chamber is opened.

[0103] In some embodiments, the control module is optionally configured to detect whether the cooking cavity is opened within a preset time when the air fryer is in the cooking finished state; if the cooking cavity is opened within the preset time, control the stop to switch to the first position; if the cooking cavity is not opened within the preset time, control the stop to stay in the second position.

[0104] In some embodiments, optionally, the control module is specifically configured to control the stop to switch to a first position when the cooking cavity is opened, in the case that the cooking cavity is opened within a preset time.

[0105] In some embodiments, the control module is optionally configured to control the stop to switch to a first position when the air fryer is in the cooking finished state.

[0106] In some embodiments, the control module is specifically configured to control the stop to switch to a first position when the air fryer is in standby mode.

[0109] The seventh aspect of this application provides a readable storage medium having a program or instructions stored thereon, which, when executed by a processor, implement the steps of a control method as described in any embodiment of the fourth aspect.

[0110] The readable storage medium provided in this application stores a program or instructions that, when executed by a processor, implement the steps of the control method as described in any of the embodiments in the fourth aspect. Therefore, it has all the beneficial effects of the control method for the air fryer described above, which will not be described in detail here.

Detailed Implementation

[0125] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0126] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0127] The following reference Figures 1 to 8 An air fryer 10 and its control method, control device and readable storage medium according to some embodiments of this application.

[0128] like Figure 1 , Figure 2 and Figure 3 As shown, an air fryer 10 according to some embodiments of this application includes: a shell assembly 100, with a cooking cavity 110 inside the shell assembly 100; a fan blade 300 located inside the cooking cavity 110; a magnetic disk 600, the fan blade 300 being a magnetic conductor, the magnetic disk 600 being used to drive the fan blade 300 to generate heat; and a limiting structure 400 disposed on the shell assembly 100, the limiting structure 400 including a stop member 410, the stop member 410 being movable relative to the shell assembly 100 to switch between a first position and a second position; when the stop member 410 is in the first position, the stop member 410 is used to restrict the rotation of the fan blade 300; when the stop member 410 is in the second position, the stop member 410 releases the restriction on the fan blade 300, and the fan blade 300 is able to rotate.

[0129] An air fryer 10 provided in this application includes a shell assembly 100, a fan blade 300, an electric disk 600, and a limiting structure 400.

[0130] The limiting structure 400 is disposed on the housing assembly 100. The housing assembly 100 serves as the mounting carrier for the limiting structure 400 and has the function of installing and fixing the limiting structure 400.

[0131] The housing assembly 100 has a cooking chamber 110, and the fan blade 300 is disposed in the cooking chamber 110. Food is placed in the cooking chamber 110 and cooked in the cooking chamber 110 to meet the needs of use such as air-frying food, heating food, baking food, etc.

[0132] The limiting structure 400 includes a stop 410, which is movable relative to the housing assembly 100 to switch between a first position and a second position.

[0133] When the stop 410 is switched to the first position, the stop 410 can restrict the rotation of the fan blade 300, and the fan blade 300 cannot continue to rotate.

[0134] When the stop 410 switches to the second position, the stop 410 releases the restriction on the fan blade 300, allowing the fan blade 300 to rotate. The fan blade 300 can rotate within the cooking chamber 110 to create a hot air circulation within the cooking chamber 110, thereby achieving the purpose of cooking the food.

[0135] Optionally, the air fryer 10 includes a flip-top air fryer or a drum-type air fryer. Specifically, in a flip-top air fryer, the cooking chamber 110 is closed or opened when the lid is closed or away from the base.

[0136] It is understandable that after cooking is completed, the fan blade 300 will continue to rotate for a period of time due to inertia. In other words, after the lid is opened, there is a possibility that the fan blade 300 will continue to rotate without stopping in time.

[0137] This application, by setting a limiting structure 400, allows the stop 410 of the limiting structure 400 to switch between a first position and a second position according to specific circumstances. When the stop 410 is switched to the first position, it can restrict the rotation of the fan blade 300, causing the fan blade 300 to stop rotating in time, thereby improving the safety and reliability of product use. Specifically, in the event of accidental operation or sudden opening of the air fryer 10, the stop 410 can effectively stop the rotation of the fan blade 300, preventing it from continuing to rotate and ensuring the safety and reliability of the air fryer 10. Furthermore, because the limiting structure 400 is set, the stop 410 can effectively cooperate with the fan blade 300, so that stopping the rotation of the fan blade 300 is not limited by the weight and size of the fan blade 300, ensuring the effectiveness and feasibility of restricting the rotation of the fan blade 300. Meanwhile, due to the setting of the limit structure 400, when the motor 700 switches to stop working, the rotation time of the fan blade 300 can be effectively shortened, which can meet the usage requirements of the fan blade 300 stopping rotation.

[0138] Furthermore, the fan blade 300 is a magnetic component, and the electric disk 600 is used to drive the fan blade 300 to generate heat. When the electric disk 600 is energized, it can generate an alternating magnetic field. Under the action of the alternating magnetic field, the magnetically conductive fan blade 300 will generate heat. That is, through the interaction between the electric disk 600 and the magnetically conductive fan blade 300, the fan blade 300 can rapidly increase in temperature in a short time. At the same time, driven by the motor 700, the fan blade 300 rotates within the cooking cavity 110, thereby rapidly generating hot air within the cooking cavity 110.

[0139] Optionally, when the air fryer 10 is powered off, the stop 410 is in the first position. This stops the fan blades 300 from rotating. That is, the fan blades 300 cannot continue to rotate. In this state, even if the air fryer 10 is opened, there will be no safety hazard.

[0140] Optionally, when the air fryer 10 is in standby mode, the stop 410 is in the first position to limit the rotation of the fan blades 300.

[0141] Optionally, when the cooking cavity 110 is opened during cooking, the stop 410 is in a first position. This stops the fan blades 300 from rotating, preventing accidental injury to the user.

[0142] Optionally, when cooking is finished, the stop 410 is in a first position to limit the rotation of the fan blade 300.

[0143] Optionally, when the cooking chamber 110 is opened within a preset time after cooking is completed, the stop 410 is in a first position to limit the rotation of the fan blades 300.

[0144] Optionally, when the cooking cavity 110 is closed within a preset time after cooking, the stop 410 is in the second position. At this time, there is no need to control the stop 410 to switch to the first position, and the fan blade 300 can automatically stop rotating. This reduces the number of contacts between the stop 410 and the fan blade 300, that is, it reduces the number of times the fan blade 300 is actively stopped during the service life of the air fryer 10, which helps to extend the service life of the stop 410 and the fan blade 300.

[0145] Optionally, when the air fryer 10 is in the cooking state, the stop 410 is in the second position. This releases the restriction on the fan blades 300, allowing the fan blades 300 to rotate under the action of the motor 700 to achieve the cooking purpose.

[0146] In some embodiments, optionally, such as Figure 1 and Figure 2As shown, one of the stop member 410 and the fan blade 300 has a positioning part 1200. When the stop member 410 is in the first position, the positioning part 1200 cooperates with the other of the stop member 410 and the fan blade 300, and the fan blade 300 cannot rotate.

[0147] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined.

[0148] Specifically, one of the stop 410 and the fan blade 300 has a positioning part 1200, which is used to cooperate with the other of the stop 410 and the fan blade 300.

[0149] When the stop 410 is in the first position, the positioning part 1200 cooperates with the other of the stop 410 and the fan blade 300, so that the fan blade 300 cannot rotate, thereby achieving the purpose of stopping the fan blade 300 from rotating.

[0150] In some embodiments, optionally, when the stop 410 is in the first position, the stop 410 abuts against the fan blade 300, and when the stop 410 is in the second position, the stop 410 separates from the fan blade 300.

[0151] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined.

[0152] Specifically, when the stop member 410 is in the first position, the stop member 410 can contact the fan blade 300 to prevent the fan blade 300 from continuing to rotate, thereby achieving the purpose of stopping the fan blade 300 from rotating.

[0153] Specifically, when the stop 410 is in the second position, the stop 410 is separated from the fan blade 300, that is, the resistance of the stop 410 acting on the fan blade 300 is removed, and the fan blade 300 can rotate under the action of the motor 700 of the cooking appliance so that hot air circulation is formed in the cooking cavity 110.

[0154] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, when the stop member 410 is in the first position, the surfaces of the stop member 410 and the fan blade 300 that are in contact with each other are respectively referred to as the first mating surface 510 and the second mating surface 520, and at least one of the first mating surface 510 and the second mating surface 520 has a limiting portion.

[0155] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined, such that the stop 410 includes a first mating surface 510 and the fan blade 300 includes a second mating surface 520. When the stop 410 is in the first position, the first mating surface 510 and the second mating surface 520 abut against each other.

[0156] At least one of the first mating surface 510 and the second mating surface 520 has a limiting portion. That is, the first mating surface 510 has a limiting portion, or the second mating surface 520 has a limiting portion, or both the first mating surface 510 and the second mating surface 520 have limiting portions. The limiting portion can increase the resistance when the stop member 410 and the fan blade 300 abut, and can prevent the fan blade 300 from continuing to rotate.

[0157] Optionally, the limiting portion includes convex and concave surfaces and / or surfaces with high roughness.

[0158] In some embodiments, optionally, such as Figure 1 As shown, the stop 410 can move along the height direction of the housing assembly 100.

[0159] In this embodiment, the movement trajectory of the stop 410 is further defined, so that the stop 410 can move along the height direction of the housing assembly 100 to switch between a first position and a second position.

[0160] Optionally, the stop 410 is switched downward along the height direction of the housing assembly 100 to a first position, and the stop 410 is switched upward along the height direction of the housing assembly 100 to a second position.

[0161] For example, the stop 410 moves downward along the height direction of the housing assembly 100 to a first position to abut against the fan blade 300.

[0162] For example, the stop 410 moves upward along the height direction of the housing assembly 100 to a second position to separate from the fan blade 300.

[0163] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, the air fryer 10 also includes: a drive member 420, which drives the stop member 410 to move; a protective cover 800, which is disposed in the cooking cavity 110, and the protective cover 800 and the cavity wall of the cooking cavity 110 enclose an installation cavity 900, the fan blade 300 is located in the installation cavity 900, and the protective cover 800 is provided with an outlet 810, which connects the installation cavity 900 and the cooking cavity 110.

[0164] In this embodiment, the composition of the air fryer 10 is further defined.

[0165] Specifically, the air fryer 10 also includes a drive member 420, which drives the stop member 410 to move so that the stop member 410 can switch between a first position and a second position. For example, the stop member 410 is extended into the cooking cavity 110, or the stop member 410 is withdrawn from the cooking cavity 110.

[0166] Specifically, the drive unit 420 includes an electromagnet and / or a pump body and / or an electric motor. For example, the drive unit 420 includes an electromagnet; for example, the drive unit 420 includes a pump body; for example, the drive unit 420 includes both an electromagnet and a pump body.

[0167] When the driving component 420 includes an electromagnet, the electromagnet, when energized, can drive the stop 410 to switch to the second position, disengaging the stop 410 from the fan blade 300, allowing the fan blade 300 to rotate normally. When the electromagnet is de-energized, the stop 410 presses against the fan blade 300, preventing or hindering its rotation, thus stopping the fan blade 300 from rotating.

[0168] When the drive component 420 includes a pump body (e.g., an air pump, an oil pump, etc.), the pump body drives the stop 410 to extend to the first position. The stop 410 presses against the fan blade 300, preventing the fan blade 300 from rotating or making it difficult to rotate, thereby stopping the fan blade 300 from rotating. The pump body drives the stop 410 to retract to the second position, whereby the stop 410 moves away from the fan blade 300, allowing the fan blade 300 to rotate normally.

[0169] In this embodiment, the structure of the air fryer 10 is defined such that the air fryer 10 also includes a protective cover 800, which is disposed inside the cooking cavity 110 and connected to the cavity wall of the cooking cavity 110 to enclose the mounting cavity 900.

[0170] The mounting cavity 900 serves to mount and fix the fan blades 300.

[0171] The protective cover 800 is provided with an outlet 810, which is connected to the mounting cavity 900, ensuring that hot air can effectively flow from the mounting cavity 900 into the cooking cavity 110.

[0172] Understandably, the protective cover 800 separates the internal space of the cooking cavity 110 into the mounting cavity 900. This arrangement serves to protect the fan blades 300 and also ensures that hot air circulates between the mounting cavity 900 and the area outside the mounting cavity 900.

[0173] Furthermore, the protective cover 800 prevents users' hands from touching the fan blades 300, thus avoiding burns and improving the safety and reliability of the air fryer 10. The protective cover 800 also protects the fan blades 300, preventing direct external force from affecting them and reducing the probability of damage, thereby extending their lifespan.

[0174] In some embodiments, optionally, such as Figure 1As shown, the housing assembly 100 also includes a mounting plate 1000 located on the side of the drive member 420 facing the fan blade 300. The mounting plate 1000 includes: an inner cover 120 located between the cooking cavity 110 and the drive member 420, and a stop member 410 passing through the inner cover 120 and extending into the cooking cavity 110; or, a heat insulation sub-plate 130 forming part of the cavity wall of the cooking cavity 110, and the stop member 410. The inner cover 120 and the inner cover 130 extend into the cooking cavity 110; or, the inner cover 120 and the inner cover 130 are located between the cooking cavity 110 and the drive member 420, the inner cover 120 is provided with a through hole 1100, the electric disk 600 is located between the inner cover 130 and the inner cover 120, the inner cover 130 forms part of the cavity wall of the cooking cavity 110, and the stop member 410 extends into the cooking cavity 110 through the inner cover 120 and the through hole 1100.

[0175] In this embodiment, the structure of the housing assembly 100 is further defined such that the housing assembly 100 also includes a mounting plate 1000.

[0176] The mounting plate 1000 includes an inner cover 120, which is located between the cooking cavity 110 and the drive member 420. That is, the inner cover 120 serves to separate the cooking cavity 110 and the drive member 420.

[0177] The stop 410 passes through the inner cover 120 and extends into the cooking cavity 110. For example, the stop 410 and the drive 420 are connected. The stop 410 passes through the inner cover 120, and the drive 420 can drive the stop 410 to extend into the cooking cavity 110 or to withdraw from the cooking cavity 110.

[0178] It is understandable that the inner cover 120 is located between the cooking cavity 110 and the drive member 420, or in other words, the inner cover 120 is also provided between the drive member 420 and the cooking cavity 110. That is, the drive member 420 is set independently of the cooking cavity 110. In this way, it can not only meet the usage requirements of the drive member 420 driving the stop member 410 to move, but also prevent the hot air in the cooking cavity 110 from flowing to the drive member 420, which can reduce heat transfer and help lower the temperature at the drive member 420. This provides an effective and reliable structural support for extending the service life of the drive member 420.

[0179] Mounting plate 1000 includes a heat insulation sub-plate 130, which forms part of the cavity wall of cooking cavity 110. Stop 410 passes through heat insulation sub-plate 130 and extends into cooking cavity 110. Heat insulation sub-plate 130 has a heat insulation function, reducing the heat transferred from cooking cavity 110 to the rest of air fryer 10.

[0180] The mounting plate 1000 includes an inner cover 120 and a heat insulation sub-plate 130. The inner cover 120 is located between the cooking cavity 110 and the drive member 420. The heat insulation sub-plate 130 has a through hole 1100. The electric disk 600 is located between the heat insulation sub-plate 130 and the inner cover 120. The heat insulation sub-plate 130 forms part of the cavity wall of the cooking cavity 110. The stop member 410 extends into the cooking cavity 110 through the inner cover 120 and the through hole 1100. Specifically, the heat insulation sub-plate 130 has a first end face and a second end face in the thickness direction. The first end face forms part of the cavity wall of the cooking cavity 110, and the second end face faces the electric disk 600. The heat insulation sub-plate 130 serves to separate the cooking cavity 110 and the electric disk 600. That is, the electric disk 600 is set independently of the cooking cavity 110. This design not only meets the heating requirements of the fan blades 300 driven by the electric disk 600, but also prevents hot air from flowing from the cooking cavity 110 to the electric disk 600, thus reducing heat transfer and lowering the temperature of the electric disk 600. This provides effective and reliable structural support for extending the service life of the electric disk 600.

[0181] Understandably, when the electric disk 600 is energized, it generates an alternating magnetic field. Under the influence of this alternating magnetic field, the magnetically conductive fan blades 300 generate heat. Through the interaction between the electric disk 600 and the magnetically conductive fan blades 300, the fan blades 300 can rapidly increase in temperature within a short time. Simultaneously, driven by the motor 700, the fan blades 300 rotate within the cooking cavity 110, causing hot air to be rapidly generated within the cooking cavity 110.

[0182] It is understandable that the heat insulation sub-plate 130 is provided with a through hole 1100, and the stop member 410 extends into the cooking cavity 110 through the through hole 1100. That is, the stop member 410 passes through the inner cover 120 and the heat insulation sub-plate 130 in sequence and then extends into the cooking cavity 110.

[0183] In some embodiments, optionally, such as Figure 3 As shown, the air fryer 10 also includes a motor 700, which and the drive unit 420 are located on the same side of the mounting plate 1000. The motor 700 has a drive shaft 710 that passes through the mounting plate 1000 and is connected to the fan blade 300.

[0184] In this embodiment, the structure of the air fryer 10 is further defined such that the air fryer 10 also includes a motor 700, the motor 700 having a drive shaft 710 that passes through the mounting plate 1000 and is connected to the fan blades 300. The motor 700 can drive the fan blades 300 to rotate, so as to achieve the purpose of circulating hot air within the cooking chamber 110.

[0185] The motor 700 and the drive unit 420 are located on the same side of the mounting plate 1000. That is, the motor 700 and the drive unit 420 are arranged separately from the magnetic disk 600 through the mounting plate 1000. The magnetic disk 600 can generate heat when it is working. The mounting plate 1000 has the function of reducing the heat transferred to the motor 700 and the drive unit 420, which can ensure the ambient temperature of the motor 700 and the drive unit 420 and provide reliable structural support for ensuring the service life of the motor 700 and the drive unit 420.

[0186] Optionally, the housing assembly 100 is provided with an air vent, which is connected to the motor 700 and the drive unit 420, and is also connected to the electric disk 600.

[0187] like Figure 1 , Figure 2 and Figure 3 As shown, an air fryer 10 according to some embodiments of this application includes: a shell assembly 100, the shell assembly 100 having a cooking cavity 110 therein; a fan blade 300 located within the cooking cavity 110; and a limiting structure 400 disposed on the shell assembly 100, the limiting structure 400 including a stop member 410, the stop member 410 being movable relative to the shell assembly 100 to switch between a first position and a second position; when the stop member 410 is in the first position, the stop member 410 is used to restrict the rotation of the fan blade 300; when the stop member 410 is in the second position, the stop member 410 releases the restriction on the fan blade 300, and the fan blade 300 is able to rotate.

[0188] An air fryer 10 provided in this application includes a shell assembly 100, a fan blade 300, and a limiting structure 400.

[0189] The limiting structure 400 is disposed on the housing assembly 100. The housing assembly 100 serves as the mounting carrier for the limiting structure 400 and has the function of installing and fixing the limiting structure 400.

[0190] The housing assembly 100 has a cooking chamber 110, and the fan blade 300 is disposed in the cooking chamber 110. Food is placed in the cooking chamber 110 and cooked in the cooking chamber 110 to meet the needs of use such as air-frying food, heating food, baking food, etc.

[0191] The limiting structure 400 includes a stop 410, which is movable relative to the housing assembly 100 to switch between a first position and a second position.

[0192] When the stop 410 is switched to the first position, the stop 410 can restrict the rotation of the fan blade 300, and the fan blade 300 cannot continue to rotate.

[0193] When the stop 410 switches to the second position, the stop 410 releases the restriction on the fan blade 300, allowing the fan blade 300 to rotate. The fan blade 300 can rotate within the cooking chamber 110 to create a hot air circulation within the cooking chamber 110, thereby achieving the purpose of cooking the food.

[0194] Optionally, the air fryer 10 includes a flip-top air fryer or a drum-type air fryer. Specifically, in a flip-top air fryer, the cooking chamber 110 is closed or opened when the lid is closed or away from the base.

[0195] It is understandable that after cooking is completed, the fan blade 300 will continue to rotate for a period of time due to inertia. In other words, after the lid is opened, there is a possibility that the fan blade 300 will continue to rotate without stopping in time.

[0196] This application, by setting a limiting structure 400, allows the stop 410 of the limiting structure 400 to switch between a first position and a second position according to specific circumstances. When the stop 410 is switched to the first position, it can restrict the rotation of the fan blade 300, causing the fan blade 300 to stop rotating in time, thereby improving the safety and reliability of product use. Specifically, in the event of accidental operation or sudden opening of the air fryer 10, the stop 410 can effectively stop the rotation of the fan blade 300, preventing it from continuing to rotate and ensuring the safety and reliability of the air fryer 10. Furthermore, because the limiting structure 400 is set, the stop 410 can effectively cooperate with the fan blade 300, so that stopping the rotation of the fan blade 300 is not limited by the weight and size of the fan blade 300, ensuring the effectiveness and feasibility of restricting the rotation of the fan blade 300. Meanwhile, due to the setting of the limit structure 400, when the motor 700 switches to stop working, the rotation time of the fan blade 300 can be effectively shortened, which can meet the usage requirements of the fan blade 300 stopping rotation.

[0197] Optionally, when the air fryer 10 is powered off, the stop 410 is in the first position. This stops the fan blades 300 from rotating. That is, the fan blades 300 cannot continue to rotate. In this state, even if the air fryer 10 is opened, there will be no safety hazard.

[0198] Optionally, when the air fryer 10 is in standby mode, the stop 410 is in the first position to limit the rotation of the fan blades 300.

[0199] Optionally, when the cooking cavity 110 is opened during cooking, the stop 410 is in a first position. This stops the fan blades 300 from rotating, preventing accidental injury to the user.

[0200] Optionally, when cooking is finished, the stop 410 is in a first position to limit the rotation of the fan blade 300.

[0201] Optionally, when the cooking chamber 110 is opened within a preset time after cooking is completed, the stop 410 is in a first position to limit the rotation of the fan blades 300.

[0202] Optionally, when the cooking cavity 110 is closed within a preset time after cooking, the stop 410 is in the second position. At this time, there is no need to control the stop 410 to switch to the first position, and the fan blade 300 can automatically stop rotating. This reduces the number of contacts between the stop 410 and the fan blade 300, that is, it reduces the number of times the fan blade 300 is actively stopped during the service life of the air fryer 10, which helps to extend the service life of the stop 410 and the fan blade 300.

[0203] Optionally, when the air fryer 10 is in the cooking state, the stop 410 is in the second position. This releases the restriction on the fan blades 300, allowing the fan blades 300 to rotate under the action of the motor 700 to achieve the cooking purpose.

[0204] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, one of the stop member 410 and the fan blade 300 has a positioning part 1200. When the stop member 410 is in the first position, the positioning part 1200 cooperates with the other of the stop member 410 and the fan blade 300, and the fan blade 300 cannot rotate.

[0205] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined.

[0206] Specifically, one of the stop 410 and the fan blade 300 has a positioning part 1200, which is used to cooperate with the other of the stop 410 and the fan blade 300.

[0207] When the stop 410 is in the first position, the positioning part 1200 cooperates with the other of the stop 410 and the fan blade 300, so that the fan blade 300 cannot rotate, thereby achieving the purpose of stopping the fan blade 300 from rotating.

[0208] In some embodiments, optionally, when the stop 410 is in the first position, the stop 410 abuts against the fan blade 300, and when the stop 410 is in the second position, the stop 410 separates from the fan blade 300.

[0209] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined.

[0210] Specifically, when the stop member 410 is in the first position, the stop member 410 can contact the fan blade 300 to prevent the fan blade 300 from continuing to rotate, thereby achieving the purpose of stopping the fan blade 300 from rotating.

[0211] Specifically, when the stop 410 is in the second position, the stop 410 is separated from the fan blade 300, that is, the resistance of the stop 410 acting on the fan blade 300 is removed, and the fan blade 300 can rotate under the action of the motor 700 of the cooking appliance so that hot air circulation is formed in the cooking cavity 110.

[0212] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, when the stop member 410 is in the first position, the surfaces of the stop member 410 and the fan blade 300 that are in contact with each other are respectively referred to as the first mating surface 510 and the second mating surface 520, and at least one of the first mating surface 510 and the second mating surface 520 has a limiting portion.

[0213] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined, such that the stop 410 includes a first mating surface 510 and the fan blade 300 includes a second mating surface 520. When the stop 410 is in the first position, the first mating surface 510 and the second mating surface 520 abut against each other.

[0214] At least one of the first mating surface 510 and the second mating surface 520 has a limiting portion. That is, the first mating surface 510 has a limiting portion, or the second mating surface 520 has a limiting portion, or both the first mating surface 510 and the second mating surface 520 have limiting portions. The limiting portion can increase the resistance when the stop member 410 and the fan blade 300 abut, and can prevent the fan blade 300 from continuing to rotate.

[0215] Optionally, the limiting portion includes convex and concave surfaces and / or surfaces with high roughness.

[0216] In some embodiments, optionally, such as Figure 1 As shown, the stop 410 can move along the height direction of the housing assembly 100.

[0217] In this embodiment, the movement trajectory of the stop 410 is further defined, so that the stop 410 can move along the height direction of the housing assembly 100 to switch between a first position and a second position.

[0218] Optionally, the stop 410 is switched downward along the height direction of the housing assembly 100 to a first position, and the stop 410 is switched upward along the height direction of the housing assembly 100 to a second position.

[0219] For example, the stop 410 moves downward along the height direction of the housing assembly 100 to a first position to abut against the fan blade 300.

[0220] For example, the stop 410 moves upward along the height direction of the housing assembly 100 to a second position to separate from the fan blade 300.

[0221] In some embodiments, optionally, such as Figure 1 As shown, the housing assembly 100 also includes a mounting plate 1000 located on the side of the drive member 420 facing the fan blade 300. The mounting plate 1000 includes: an inner cover 120 located between the cooking chamber 110 and the drive member 420, with a stop member 410 passing through the inner cover 120 and extending into the cooking chamber 110; or, a heat insulation sub-plate 130 forming a portion of the cavity wall of the cooking chamber 110, with the stop member 410 passing through the heat insulation sub-plate 130 and extending into the cooking chamber 110; or, an inner cover 120 and a heat insulation sub-plate 130, with the inner cover 120 located between the cooking chamber 110 and the drive member 420, the heat insulation sub-plate 130 forming a portion of the cavity wall of the cooking chamber 110, the heat insulation sub-plate 130 having a through hole 1100, and the stop member 410 passing through the inner cover 120 and the through hole 1100 and extending into the cooking chamber 110.

[0222] In this embodiment, the structure of the housing assembly 100 is further defined such that the housing assembly 100 also includes a mounting plate 1000.

[0223] The mounting plate 1000 includes an inner cover 120, which is located between the cooking cavity 110 and the drive member 420. That is, the inner cover 120 serves to separate the cooking cavity 110 and the drive member 420.

[0224] The stop 410 passes through the inner cover 120 and extends into the cooking cavity 110. For example, the stop 410 and the drive 420 are connected. The stop 410 passes through the inner cover 120, and the drive 420 can drive the stop 410 to extend into the cooking cavity 110 or to withdraw from the cooking cavity 110.

[0225] It is understandable that the inner cover 120 is located between the cooking cavity 110 and the drive member 420, or in other words, the inner cover 120 is also provided between the drive member 420 and the cooking cavity 110. That is, the drive member 420 is set independently of the cooking cavity 110. In this way, it can not only meet the usage requirements of the drive member 420 driving the stop member 410 to move, but also prevent the hot air in the cooking cavity 110 from flowing to the drive member 420, which can reduce heat transfer and help lower the temperature at the drive member 420. This provides an effective and reliable structural support for extending the service life of the drive member 420.

[0226] Mounting plate 1000 includes a heat insulation sub-plate 130, which forms part of the cavity wall of cooking cavity 110. Stop 410 passes through heat insulation sub-plate 130 and extends into cooking cavity 110. Heat insulation sub-plate 130 has a heat insulation function, reducing the heat transferred from cooking cavity 110 to the rest of air fryer 10.

[0227] The mounting plate 1000 includes an inner cover 120 and a heat insulation sub-plate 130. The inner cover 120 is located between the cooking cavity 110 and the drive member 420. The heat insulation sub-plate 130 forms part of the cavity wall of the cooking cavity 110. The heat insulation sub-plate 130 is provided with a through hole 1100. A stop member 410 passes through the inner cover 120 and the through hole 1100 and extends into the cooking cavity 110. The stop member 410 passes through the inner cover 120 and the heat insulation sub-plate 130 in sequence and then extends into the cooking cavity 110.

[0228] like Figure 1 , Figure 2 and Figure 3 As shown, an air fryer 10 according to some embodiments of this application includes: a shell assembly 100, the shell assembly 100 having a cooking cavity 110 therein; a fan blade 300 located within the cooking cavity 110; a magnetic disk 600, the fan blade 300 being a magnetic conductor, the magnetic disk 600 being used to drive the fan blade 300 to generate heat; and a limiting structure 400 disposed on the shell assembly 100, the limiting structure 400 including a stop member 410, the stop member 410 being movable relative to the shell assembly 100 to switch between a first position and a second position, the stop member 410 being in the first position, the stop member 410 being used to limit the rotation of the fan blade 300, and the stop member 410 being in the second position... The stop 410 releases the restriction on the fan blade 300, allowing the fan blade 300 to rotate. When the air fryer 10 is in the first state, the stop 410 is in the first position. The first state includes a power-off state, a standby state, or a state where the cooking cavity 110 is open during cooking. When the air fryer 10 is in the second state, the stop 410 is in the first position, or when the air fryer 10 is in the third state, the stop 410 is in the second position. The second state includes a cooking-finished state or a state where the cooking cavity 110 is open within a preset time after cooking. The third state includes a cooking cavity 110 being closed within a preset time after cooking or a cooking state.

[0229] An air fryer 10 provided in this application includes a shell assembly 100, a fan blade 300, an electric disk 600, and a limiting structure 400.

[0230] The limiting structure 400 is disposed on the housing assembly 100. The housing assembly 100 serves as the mounting carrier for the limiting structure 400 and has the function of installing and fixing the limiting structure 400.

[0231] The housing assembly 100 has a cooking chamber 110, and the fan blade 300 is disposed in the cooking chamber 110. Food is placed in the cooking chamber 110 and cooked in the cooking chamber 110 to meet the needs of use such as air-frying food, heating food, baking food, etc.

[0232] The limiting structure 400 includes a stop 410, which is movable relative to the housing assembly 100 to switch between a first position and a second position.

[0233] When the stop 410 is switched to the first position, the stop 410 can restrict the rotation of the fan blade 300, and the fan blade 300 cannot continue to rotate.

[0234] When the stop 410 switches to the second position, the stop 410 releases the restriction on the fan blade 300, allowing the fan blade 300 to rotate. The fan blade 300 can rotate within the cooking chamber 110 to create a hot air circulation within the cooking chamber 110, thereby achieving the purpose of cooking the food.

[0235] Optionally, the air fryer 10 includes a flip-top air fryer or a drum-type air fryer. Specifically, in a flip-top air fryer, the cooking chamber 110 is closed or opened when the lid is closed or away from the base.

[0236] It is understandable that after cooking is completed, the fan blade 300 will continue to rotate for a period of time due to inertia. In other words, after the lid is opened, there is a possibility that the fan blade 300 will continue to rotate without stopping in time.

[0237] This application, by setting a limiting structure 400, allows the stop 410 of the limiting structure 400 to switch between a first position and a second position according to specific circumstances. When the stop 410 is switched to the first position, it can restrict the rotation of the fan blade 300, causing the fan blade 300 to stop rotating in time, thereby improving the safety and reliability of product use. Specifically, in the event of accidental operation or sudden opening of the air fryer 10, the stop 410 can effectively stop the rotation of the fan blade 300, preventing it from continuing to rotate and ensuring the safety and reliability of the air fryer 10. Furthermore, because the limiting structure 400 is set, the stop 410 can effectively cooperate with the fan blade 300, so that stopping the rotation of the fan blade 300 is not limited by the weight and size of the fan blade 300, ensuring the effectiveness and feasibility of restricting the rotation of the fan blade 300. Meanwhile, due to the setting of the limit structure 400, when the motor 700 switches to stop working, the rotation time of the fan blade 300 can be effectively shortened, which can meet the usage requirements of the fan blade 300 stopping rotation.

[0238] Furthermore, the fan blade 300 is a magnetic component, and the electric disk 600 is used to drive the fan blade 300 to generate heat. When the electric disk 600 is energized, it can generate an alternating magnetic field. Under the action of the alternating magnetic field, the magnetically conductive fan blade 300 will generate heat. That is, through the interaction between the electric disk 600 and the magnetically conductive fan blade 300, the fan blade 300 can rapidly increase in temperature in a short time. At the same time, driven by the motor 700, the fan blade 300 rotates within the cooking cavity 110, thereby rapidly generating hot air within the cooking cavity 110.

[0239] Optionally, when the air fryer 10 is in the first state (e.g., power off state), the stop 410 is in the first position. This stops the fan blades 300 from rotating. That is, the fan blades 300 cannot continue to rotate. In this state, even if the air fryer 10 is opened, there will be no safety hazard.

[0240] Optionally, when the air fryer 10 is in a first state (e.g., standby state), the stop 410 is in a first position to limit the rotation of the fan blades 300.

[0241] Optionally, when the air fryer 10 is in a first state (e.g., the cooking chamber 110 is open during cooking), the stop 410 is in a first position. This is to limit the rotation of the fan blades 300 and prevent accidental injury to the user.

[0242] Optionally, when the air fryer 10 is in the second state (e.g., cooking end state), the stop 410 is in the first position to limit the rotation of the fan blades 300.

[0243] Optionally, when the air fryer 10 is in the second state (e.g., the cooking cavity 110 is opened within a preset time after cooking is completed), the stop 410 is in the first position. This is to limit the rotation of the fan blades 300 using the stop 410.

[0244] Optionally, when the air fryer 10 is in the third state (e.g., the cooking cavity 110 is closed within a preset time after cooking), the stop 410 is in the second position. At this time, there is no need to control the stop 410 to switch to the first position, and the fan blades 300 can automatically stop rotating. This reduces the number of contacts between the stop 410 and the fan blades 300, that is, it reduces the number of times the fan blades 300 are actively stopped during the service life of the air fryer 10, which helps to extend the service life of both the stop 410 and the fan blades 300.

[0245] Optionally, when the air fryer 10 is in the third state (e.g., cooking state), the stop 410 is in the second position. This releases the restriction on the fan blades 300, allowing the fan blades 300 to rotate under the action of the motor 700 to achieve the cooking purpose.

[0246] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, one of the stop member 410 and the fan blade 300 has a positioning part 1200. When the stop member 410 is in the first position, the positioning part 1200 cooperates with the other of the stop member 410 and the fan blade 300, and the fan blade 300 cannot rotate.

[0247] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined.

[0248] Specifically, one of the stop 410 and the fan blade 300 has a positioning part 1200, which is used to cooperate with the other of the stop 410 and the fan blade 300.

[0249] When the stop 410 is in the first position, the positioning part 1200 cooperates with the other of the stop 410 and the fan blade 300, so that the fan blade 300 cannot rotate, thereby achieving the purpose of stopping the fan blade 300 from rotating.

[0250] In some embodiments, optionally, when the stop 410 is in the first position, the stop 410 abuts against the fan blade 300, and when the stop 410 is in the second position, the stop 410 separates from the fan blade 300.

[0251] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined.

[0252] Specifically, when the stop member 410 is in the first position, the stop member 410 can contact the fan blade 300 to prevent the fan blade 300 from continuing to rotate, thereby achieving the purpose of stopping the fan blade 300 from rotating.

[0253] Specifically, when the stop 410 is in the second position, the stop 410 is separated from the fan blade 300, that is, the resistance of the stop 410 acting on the fan blade 300 is removed, and the fan blade 300 can rotate under the action of the motor 700 of the cooking appliance so that hot air circulation is formed in the cooking cavity 110.

[0254] In some embodiments, optionally, such as Figure 1 and Figure 2 As shown, when the stop member 410 is in the first position, the surfaces of the stop member 410 and the fan blade 300 that are in contact with each other are respectively referred to as the first mating surface 510 and the second mating surface 520, and at least one of the first mating surface 510 and the second mating surface 520 has a limiting portion.

[0255] In this embodiment, the mating structure of the stop 410 and the fan blade 300 is further defined, such that the stop 410 includes a first mating surface 510 and the fan blade 300 includes a second mating surface 520. When the stop 410 is in the first position, the first mating surface 510 and the second mating surface 520 abut against each other.

[0256] At least one of the first mating surface 510 and the second mating surface 520 has a limiting portion. That is, the first mating surface 510 has a limiting portion, or the second mating surface 520 has a limiting portion, or both the first mating surface 510 and the second mating surface 520 have limiting portions. The limiting portion can increase the resistance when the stop member 410 and the fan blade 300 abut, and can prevent the fan blade 300 from continuing to rotate.

[0257] Optionally, the limiting portion includes convex and concave surfaces and / or surfaces with high roughness.

[0258] In some embodiments, optionally, such as Figure 1 As shown, the stop 410 can move along the height direction of the housing assembly 100.

[0259] In this embodiment, the movement trajectory of the stop 410 is further defined, so that the stop 410 can move along the height direction of the housing assembly 100 to switch between a first position and a second position.

[0260] Optionally, the stop 410 is switched downward along the height direction of the housing assembly 100 to a first position, and the stop 410 is switched upward along the height direction of the housing assembly 100 to a second position.

[0261] For example, the stop 410 moves downward along the height direction of the housing assembly 100 to a first position to abut against the fan blade 300.

[0262] For example, the stop 410 moves upward along the height direction of the housing assembly 100 to a second position to separate from the fan blade 300.

[0263] In some embodiments, the air fryer 10 may optionally include: a drive member 420 for driving the stop member 410 to move; a protective cover 800 disposed in the cooking cavity 110, the protective cover 800 and the cavity wall of the cooking cavity 110 enclosing a mounting cavity 900, the fan blade 300 being located in the mounting cavity 900, the protective cover 800 being provided with a flow port 810, the flow port 810 communicating with the mounting cavity 900 and the cooking cavity 110.

[0264] In this embodiment, the composition of the air fryer 10 is further defined.

[0265] Specifically, the air fryer 10 also includes a drive member 420, which drives the stop member 410 to move so that the stop member 410 can switch between a first position and a second position. For example, the stop member 410 is extended into the cooking cavity 110, or the stop member 410 is withdrawn from the cooking cavity 110.

[0266] Specifically, the drive element 420 includes an electromagnet and / or a pump body. For example, the drive element 420 includes an electromagnet; for example, the drive element 420 includes a pump body; for example, the drive element 420 includes both an electromagnet and a pump body.

[0267] When the driving component 420 includes an electromagnet, the electromagnet, when energized, can drive the stop 410 to switch to the second position, disengaging the stop 410 from the fan blade 300, allowing the fan blade 300 to rotate normally. When the electromagnet is de-energized, the stop 410 presses against the fan blade 300, preventing or hindering its rotation, thus stopping the fan blade 300 from rotating.

[0268] When the drive component 420 includes a pump body (e.g., an air pump, an oil pump, etc.), the pump body drives the stop 410 to extend to the first position. The stop 410 presses against the fan blade 300, preventing the fan blade 300 from rotating or making it difficult to rotate, thereby stopping the fan blade 300 from rotating. The pump body drives the stop 410 to retract to the second position, whereby the stop 410 moves away from the fan blade 300, allowing the fan blade 300 to rotate normally.

[0269] In this embodiment, the structure of the air fryer 10 is defined such that the air fryer 10 also includes a protective cover 800, which is disposed inside the cooking cavity 110 and connected to the cavity wall of the cooking cavity 110 to enclose the mounting cavity 900.

[0270] The mounting cavity 900 serves to mount and fix the fan blades 300.

[0271] The protective cover 800 is provided with an outlet 810, which is connected to the mounting cavity 900, ensuring that hot air can effectively flow from the mounting cavity 900 into the cooking cavity 110.

[0272] Understandably, the protective cover 800 separates the internal space of the cooking cavity 110 into the mounting cavity 900. This arrangement serves to protect the fan blades 300 and also ensures that hot air circulates between the mounting cavity 900 and the area outside the mounting cavity 900.

[0273] Furthermore, the protective cover 800 prevents users' hands from touching the fan blades 300, thus avoiding burns and improving the safety and reliability of the air fryer 10. The protective cover 800 also protects the fan blades 300, preventing direct external force from affecting them and reducing the probability of damage, thereby extending their lifespan.

[0274] In some embodiments, optionally, such as Figure 1 As shown, the housing assembly 100 also includes a mounting plate 1000 located on the side of the drive member 420 facing the fan blade 300. The mounting plate 1000 includes: an inner cover 120 located between the cooking cavity 110 and the drive member 420, and a stop member 410 passing through the inner cover 120 and extending into the cooking cavity 110; or, a heat insulation sub-plate 130 forming part of the cavity wall of the cooking cavity 110, and the stop member 410. The inner cover 120 and the inner cover 130 extend into the cooking cavity 110; or, the inner cover 120 and the inner cover 130 are located between the cooking cavity 110 and the drive member 420, the inner cover 120 is provided with a through hole 1100, the electric disk 600 is located between the inner cover 130 and the inner cover 120, the inner cover 130 forms part of the cavity wall of the cooking cavity 110, and the stop member 410 extends into the cooking cavity 110 through the inner cover 120 and the through hole 1100.

[0275] In this embodiment, the structure of the housing assembly 100 is further defined such that the housing assembly 100 also includes a mounting plate 1000.

[0276] The mounting plate 1000 includes an inner cover 120, which is located between the cooking cavity 110 and the drive member 420. That is, the inner cover 120 serves to separate the cooking cavity 110 and the drive member 420.

[0277] The stop 410 passes through the inner cover 120 and extends into the cooking cavity 110. For example, the stop 410 and the drive 420 are connected. The stop 410 passes through the inner cover 120, and the drive 420 can drive the stop 410 to extend into the cooking cavity 110 or to withdraw from the cooking cavity 110.

[0278] It is understandable that the inner cover 120 is located between the cooking cavity 110 and the drive member 420, or in other words, the inner cover 120 is also provided between the drive member 420 and the cooking cavity 110. That is, the drive member 420 is set independently of the cooking cavity 110. In this way, it can not only meet the usage requirements of the drive member 420 driving the stop member 410 to move, but also prevent the hot air in the cooking cavity 110 from flowing to the drive member 420, which can reduce heat transfer and help lower the temperature at the drive member 420. This provides an effective and reliable structural support for extending the service life of the drive member 420.

[0279] Mounting plate 1000 includes a heat insulation sub-plate 130, which forms part of the cavity wall of cooking cavity 110. Stop 410 passes through heat insulation sub-plate 130 and extends into cooking cavity 110. Heat insulation sub-plate 130 has a heat insulation function, reducing the heat transferred from cooking cavity 110 to the rest of air fryer 10.

[0280] The mounting plate 1000 includes an inner cover 120 and a heat insulation sub-plate 130. The inner cover 120 is located between the cooking cavity 110 and the drive member 420. The heat insulation sub-plate 130 has a through hole 1100. The electric disk 600 is located between the heat insulation sub-plate 130 and the inner cover 120. The heat insulation sub-plate 130 forms part of the cavity wall of the cooking cavity 110. The stop member 410 extends into the cooking cavity 110 through the inner cover 120 and the through hole 1100. Specifically, the heat insulation sub-plate 130 has a first end face and a second end face in the thickness direction. The first end face forms part of the cavity wall of the cooking cavity 110, and the second end face faces the electric disk 600. The heat insulation sub-plate 130 serves to separate the cooking cavity 110 and the electric disk 600. That is, the electric disk 600 is set independently of the cooking cavity 110. This design not only meets the heating requirements of the fan blades 300 driven by the electric disk 600, but also prevents hot air from flowing from the cooking cavity 110 to the electric disk 600, thus reducing heat transfer and lowering the temperature of the electric disk 600. This provides effective and reliable structural support for extending the service life of the electric disk 600.

[0281] Understandably, when the electric disk 600 is energized, it generates an alternating magnetic field. Under the influence of this alternating magnetic field, the magnetically conductive fan blades 300 generate heat. Through the interaction between the electric disk 600 and the magnetically conductive fan blades 300, the fan blades 300 can rapidly increase in temperature within a short time. Simultaneously, driven by the motor 700, the fan blades 300 rotate within the cooking cavity 110, causing hot air to be rapidly generated within the cooking cavity 110.

[0282] It is understandable that the heat insulation sub-plate 130 is provided with a through hole 1100, and the stop member 410 extends into the cooking cavity 110 through the through hole 1100. That is, the stop member 410 passes through the inner cover 120 and the heat insulation sub-plate 130 in sequence and then extends into the cooking cavity 110.

[0283] In some embodiments, optionally, such as Figure 3 As shown, the air fryer 10 also includes a motor 700, which and the drive unit 420 are located on the same side of the mounting plate 1000. The motor 700 has a drive shaft 710 that passes through the mounting plate 1000 and is connected to the fan blade 300.

[0284] In this embodiment, the structure of the air fryer 10 is further defined such that the air fryer 10 also includes a motor 700, the motor 700 having a drive shaft 710 that passes through the mounting plate 1000 and is connected to the fan blades 300. The motor 700 can drive the fan blades 300 to rotate, so as to achieve the purpose of circulating hot air within the cooking chamber 110.

[0285] The motor 700 and the drive unit 420 are located on the same side of the mounting plate 1000. That is, the motor 700 and the drive unit 420 are arranged separately from the magnetic disk 600 through the mounting plate 1000. The magnetic disk 600 can generate heat when it is working. The mounting plate 1000 has the function of reducing the heat transferred to the motor 700 and the drive unit 420, which can ensure the ambient temperature of the motor 700 and the drive unit 420 and provide reliable structural support for ensuring the service life of the motor 700 and the drive unit 420.

[0286] Optionally, the housing assembly 100 is provided with an air vent, which is connected to the motor 700 and the drive unit 420, and is also connected to the electric disk 600.

[0287] Optionally, the stop 410 includes a push rod.

[0288] Optionally, the electromagnet 600 includes a support plate and a coil.

[0289] Alternatively, the insulation panel may include, but is not limited to, microcrystalline panels, glass, and mica panels.

[0290] Optionally, the heat insulation board includes a heat insulation layer, that is, a layer of heat insulation material is coated on the outer surface of the heat insulation board to prevent heat from being transferred to the electric disk 600, thereby reducing the probability of the electric disk 600 malfunctioning and reducing the maintenance cost of the air fryer 10.

[0291] Optionally, the fan blade 300 is a magnetically conductive component. For example, the fan blade 300 may be made of iron. Alternatively, the fan blade 300 may be made of an iron alloy, such as low-carbon steel, cast iron, iron-aluminum alloy, or iron-nickel alloy, etc., which will not be listed here.

[0292] Optionally, the housing assembly 100 is provided with an air vent, which is connected to the motor 700 and the drive unit 420, and is also connected to the electric disk 600.

[0293] Optionally, the air fryer 10 also includes a power board 190, with the motor 700, power board 190 and drive unit 420 located on the same side of the inner cover 120.

[0294] Optionally, this application uses a limit structure 400 and a stop 410 of the limit structure 400 to brake the fan blade 300.

[0295] like Figures 1 to 3As shown, the air fryer 10 includes a shell assembly 100, a fan blade 300, and a limiting structure 400. The shell assembly 100 includes an inner cover 120, a heat insulation plate, a front panel 140, an outer shell 150, a reflector 160, a drawer 170, a bottom cover 180, and an air outlet grille 200. An electromagnet is installed on the inner cover 120, passing through the inner cover 120 and the heat insulation plate 130 in sequence. In its natural state without power, the push rod (i.e., the stop 410) presses against the fan blade 300, preventing or hindering its rotation. When the electromagnet is energized, the push rod retracts away from the fan blade 300, allowing it to rotate normally.

[0296] A control method for an air fryer according to some embodiments of this application is used to control the air fryer. The air fryer includes a shell assembly, fan blades, and a limiting structure. The shell assembly has a cooking cavity, and the fan blades are located within the cooking cavity. The limiting structure is disposed on the shell assembly and includes a stop member. The stop member is movable relative to the shell assembly to switch between a first position and a second position. When the stop member is in the first position, it restricts the rotation of the fan blades. When the stop member is in the second position, it releases the restriction on the fan blades, allowing the fan blades to rotate. Figure 4 A flowchart of a control method according to an embodiment of this application is shown, such as... Figure 4 As shown, the control methods include:

[0297] Step 1002: Determine the working status of the air fryer based on the acquired working signal;

[0298] Step 1004: Based on the working status of the air fryer, control the stop to switch between the first position and the second position.

[0299] In the air fryer control method provided in this application, the working state of the air fryer is determined based on the acquired working signal, and the stop member is controlled to switch between a first position and a second position according to the working state of the air fryer. In other words, the working state of the air fryer affects the position of the stop member.

[0300] When the stop is in the first position, it contacts the air fryer's fan blades, preventing them from rotating further and thus stopping them, improving the safety and reliability of the product. Specifically, in case of accidental operation or sudden opening of the air fryer, the stop effectively stops the fan blades, ensuring their continued rotation and guaranteeing the safety and reliability of the air fryer. Furthermore, the ability to switch the stop to the first position allows it to effectively engage with the fan blades, making the stopping of fan blade rotation unrestricted by their weight or size, ensuring the effectiveness and timeliness of the rotation restriction. Simultaneously, the ability to switch the stop to the first position also effectively shortens the fan blade rotation time when the motor switches to a stop position, meeting the requirement for complete fan blade cessation.

[0301] When the stop is in the second position, it releases the restriction on the fan blades, allowing them to rotate. The fan blades can then rotate within the cooking cavity, creating a hot air circulation and thus achieving the purpose of cooking the food.

[0302] In some embodiments, optionally, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: controlling the stop to switch to the second position when the air fryer starts cooking; and controlling the stop to switch to the first position when the air fryer is in a power-off state or the cooking chamber is opened.

[0303] In this embodiment, the specific steps for controlling the stop to switch between the first and second positions according to the working state of the air fryer are further defined.

[0304] When the air fryer starts cooking, the control stop switches to the second position. When the stop is in the second position, it releases the restriction on the fan blades, allowing them to rotate. Driven by the motor, the fan blades rotate within the cooking chamber, creating hot air circulation and thus cooking the food.

[0305] In the event of a power outage or power failure during air fryer operation, the control stop will switch to the first position to restrict the fan blades from rotating. This prevents the fan blades from continuing to turn, eliminating any safety hazard even if the air fryer is opened, as it effectively stops the fan blades from rotating.

[0306] If the air fryer is accidentally opened during operation, causing the cooking chamber to open, the control stop will switch to the first position. This stop restricts the fan blade rotation, preventing accidental injury to the user.

[0307] This feature can improve the product's performance and market competitiveness.

[0308] In some embodiments, optionally, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: when the air fryer is in the cooking end state, detecting whether the cooking cavity is opened within a preset time; if the cooking cavity is opened within the preset time, controlling the stop to switch to the first position; if the cooking cavity is not opened within the preset time, controlling the stop to stay in the second position.

[0309] In this embodiment, the specific steps for controlling the stop to switch between the first and second positions according to the working state of the air fryer are further defined.

[0310] When the air fryer is in the finished cooking state, check whether the cooking chamber has been opened within the preset time.

[0311] If the cooking chamber is opened within the preset time, the control stop will switch to the first position to stop the fan blades from rotating. This ensures the safety and reliability of the air fryer.

[0312] If the cooking chamber is not opened within the preset time, the stop will remain in the second position. This means the stop will not contact the fan blades, and the fan blades will automatically stop rotating after a period of time. This reduces the number of times the stop and fan blades come into contact, thus reducing the number of times the fan blades need to be actively stopped during the air fryer's lifespan, which helps extend the lifespan of both the stop and the fan blades.

[0313] In some embodiments, optionally, the step of controlling the stop to switch to the first position when the cooking cavity is opened within a preset time period specifically includes: controlling the stop to switch to the first position when the cooking cavity is opened within a preset time period.

[0314] In this embodiment, the specific steps for controlling the stop to switch to the first position are further defined when the cooking cavity is opened within a preset time.

[0315] If the cooking chamber is opened within a preset time, the control stop will switch to the first position when the cooking chamber is opened. In other words, when the cooking chamber is opened, the fan blades are stopped due to the action of the stop, thus preventing accidental injury to the user and improving the safety and reliability of the product.

[0316] In some embodiments, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: when the air fryer is in the cooking end state, controlling the stop to switch to the first position.

[0317] In this embodiment, the specific steps for controlling the stop to switch between the first and second positions according to the working state of the air fryer are further defined.

[0318] Specifically, after the air fryer finishes cooking, the control stop switches to the first position. This stops the fan blades from rotating, ensuring the safety and reliability of the air fryer.

[0319] In some embodiments, the step of controlling the stop to switch between a first position and a second position according to the working state of the air fryer specifically includes: when the air fryer is in standby mode, controlling the stop to switch to the first position.

[0320] In this embodiment, the specific steps for controlling the stop to switch between the first position and the second position are further defined according to the working state of the air fryer.

[0321] When the air fryer is in standby mode, the control stop switches to the first position, where the stop presses against the fan blades, preventing them from rotating. Upon receiving a cooking signal, the control stop switches to the second position, providing structural support for the motor to drive the fan blades to rotate.

[0322] Optionally, Figure 5 A first working flowchart of an air fryer according to an embodiment of the present invention is shown, such as... Figure 5 As shown, the control methods include:

[0323] Step 1102: The electromagnet is in its unpowered natural state, and the stop is in the first position;

[0324] Step 1104, Start the process;

[0325] Step 1106: The electromagnet is switched to the energized state, and the drive stop is switched to the second position;

[0326] Step 1108, the motor rotates;

[0327] Step 1110: Unplug the power or open the lid during cooking;

[0328] Step 1112: The electromagnet switches to its unpowered, natural state, and the stop switches to the first position;

[0329] Step 1114: The motor stops working.

[0330] Optionally, Figure 6 A second workflow diagram of an air fryer according to an embodiment of the present invention is shown, such as... Figure 6 As shown, the control methods include:

[0331] Step 1202: The electromagnet is in its unpowered natural state, and the stop is in the first position.

[0332] Step 1204, Start the process;

[0333] Step 1206: The electromagnet is switched to the energized state, and the drive stop is switched to the second position;

[0334] Step 1208, the motor rotates;

[0335] Step 1210, cooking is complete;

[0336] Step 1212: The electromagnet switches to its unpowered, natural state, and the stop switches to the first position;

[0337] Step 1214: The motor stops working.

[0338] Optionally, Figure 7 A third workflow diagram of an air fryer according to an embodiment of the present invention is shown, such as... Figure 7 As shown, the control methods include:

[0339] Step 1302: The electromagnet is in its unpowered natural state, and the stop is in the first position.

[0340] Step 1304, Start the operation;

[0341] Step 1306: The electromagnet is switched to the energized state, and the drive stop is switched to the second position;

[0342] Step 1308, the motor rotates;

[0343] Step 1310, cooking is complete;

[0344] Step 1312: Is an open cover signal received within a preset time? If yes, proceed to step 1314; otherwise, proceed to step 1316.

[0345] Step 1314: The electromagnet switches to its unpowered, natural state, and the stop switches to the first position;

[0346] Step 1316, the stop is in the second position;

[0347] Step 1318: The motor stops working.

[0348] like Figure 5 , Figure 6 and Figure 7 As shown, when the air fryer is not powered on or is in standby mode, the electromagnet is not energized, the push rod pushes against the fan blades, and the fan blades do not rotate.

[0349] When the air fryer is started, the electromagnetic drive rod switches to the second position, the rod leaves the fan blades, and the motor starts to rotate.

[0350] If the power is suddenly cut off during the operation of the air fryer, the top rod will switch to the first position to stop the fan blades.

[0351] If the lid is opened during the operation of the air fryer, the lid opening detection device (such as a micro switch and / or magnetic induction switch) will determine that the lid is open, and then the top rod will switch to the first position to stop the fan blades.

[0352] After cooking is complete, there are two possible logics. First, the push rod switches to the first position, stopping the fan blades. Second, the push rod remains in the second position if no lid opening is detected within a preset time after cooking. If lid opening is detected within the preset time, the push rod switches to the first position to stop the fan blades. The second method reduces the number of braking operations throughout the machine's lifespan. The preset time is the duration for the fan blades to stop naturally from their maximum speed due to inertia. Optionally, the preset time can be greater than or equal to 30 seconds and less than or equal to 50 seconds, such as preset times of 35 seconds, 40 seconds, and 45 seconds, etc., which are not listed here.

[0353] A control device for an air fryer according to some embodiments of this application is provided for controlling the air fryer. The air fryer includes a shell assembly, fan blades, and a limiting structure. A cooking cavity is provided within the shell assembly, and the fan blades are located within the cooking cavity. The limiting structure is disposed on the shell assembly and includes a stop member. The stop member is movable relative to the shell assembly to switch between a first position and a second position. When the stop member is in the first position, it restricts the rotation of the fan blades. When the stop member is in the second position, it releases the restriction on the fan blades, allowing the fan blades to rotate. Figure 8 A structural block diagram of the control device according to this application is shown, such as... Figure 8 As shown, the control device 1400 for the air fryer includes:

[0354] The control module 1402 is used to determine the working state of the air fryer based on the acquired working signal; and to control the stop to switch between the first position and the second position based on the working state of the air fryer.

[0355] The control device for the air fryer provided in this application includes a control module. The control module determines the operating state of the air fryer based on acquired operating signals, and controls a stop member to switch between a first position and a second position according to the operating state of the air fryer. In other words, the operating state of the air fryer affects the position of the stop member.

[0356] When the stop is in the first position, it contacts the air fryer's fan blades, preventing them from rotating further and thus stopping them, improving the safety and reliability of the product. Specifically, in case of accidental operation or sudden opening of the air fryer, the stop effectively stops the fan blades, ensuring their continued rotation and guaranteeing the safety and reliability of the air fryer. Furthermore, the ability to switch the stop to the first position allows it to effectively engage with the fan blades, making the stopping of fan blade rotation unrestricted by their weight or size, ensuring the effectiveness and timeliness of the rotation restriction. Simultaneously, the ability to switch the stop to the first position also effectively shortens the fan blade rotation time when the motor switches to a stop position, meeting the requirement for complete fan blade cessation.

[0357] When the stop is switched to the second position, the stop releases its restriction on the fan blades, allowing them to rotate. The fan blades can then rotate within the cooking chamber, creating a hot air circulation and thus achieving the purpose of cooking the food.

[0358] In some embodiments, the control module 1402 is optionally configured to control the stop to switch to a second position when the air fryer starts cooking, and to control the stop to switch to a first position when the air fryer is powered off or the cooking chamber is opened.

[0359] In this embodiment, the function of the control module is further defined.

[0360] When the air fryer starts cooking, the control stop switches to the second position. When the stop is in the second position, it releases the restriction on the fan blades, allowing them to rotate. Driven by the motor, the fan blades rotate within the cooking chamber, creating hot air circulation and thus cooking the food.

[0361] In the event of a power outage or power failure during air fryer operation, the control stop will switch to the first position to restrict the fan blades from rotating. This prevents the fan blades from continuing to turn, eliminating any safety hazard even if the air fryer is opened, as it effectively stops the fan blades from rotating.

[0362] If the air fryer is accidentally opened during operation, causing the cooking chamber to open, the control stop will switch to the first position. This stop restricts the fan blade rotation, preventing accidental injury to the user.

[0363] This feature can improve the product's performance and market competitiveness.

[0365] In this embodiment, the function of the control module is further defined.

[0366] When the air fryer is in the finished cooking state, check whether the cooking chamber has been opened within the preset time.

[0367] If the cooking chamber is opened within the preset time, the control stop will switch to the first position to stop the fan blades from rotating. This ensures the safety and reliability of the air fryer.

[0368] If the cooking chamber is not opened within the preset time, the stop will remain in the second position. This means the stop will not contact the fan blades, and the fan blades will automatically stop rotating after a period of time. This reduces the number of times the stop and fan blades come into contact, thus reducing the number of times the fan blades need to be actively stopped during the air fryer's lifespan, which helps extend the lifespan of both the stop and the fan blades.

[0369] In some embodiments, optionally, the control module 1402 is specifically configured to control the stop to switch to a first position when the cooking cavity is opened, in the case that the cooking cavity is opened within a preset time.

[0370] In this embodiment, the specific steps for controlling the stop to switch to the first position are further defined when the cooking cavity is opened within a preset time.

[0371] If the cooking chamber is opened within a preset time, the control stop will switch to the first position when the cooking chamber is opened. In other words, when the cooking chamber is opened, the fan blades are stopped due to the action of the stop, thus preventing accidental injury to the user and improving the safety and reliability of the product.

[0372] In some embodiments, optionally, the control module 1402 is specifically configured to control the stop to switch to a first position when the air fryer is in the cooking finished state.

[0373] In this embodiment, after the air fryer finishes cooking, the control stop switches to the first position to stop the fan blades from rotating, ensuring the safety and reliability of the air fryer.
