Description

Technical Field

[0001] This utility model relates to the field of kitchen cooking, specifically to an air cooking device that mainly uses hot airflow to achieve the cooking effect of air frying food. Background Technology

[0002] Existing air-cooking devices mainly include air fryers. Their primary structure for generating hot airflow involves using heating elements to produce radiant heat, which is then guided by a fan to deliver the hot airflow to the food area, achieving the air-frying effect. However, with this structure, splattered oil and residue adhere to the heating elements, making them difficult to clean. Some air fryers use electromagnetic coils to directly heat the fan blades to generate hot airflow. However, the curved structure of the fan blades, which agitate the air, results in poor induction heating stability, leading to ineffective heating and consequently poor air-frying results. This also presents cleaning challenges, all of which negatively impact the user experience. Utility Model Content

[0021] In the aforementioned air cooking device, a magnetic shielding part is provided between the induction heating part and the agitation part to shield the magnetic field, and the magnetic shielding part is configured to be heat-conducting.

[0022] Alternatively, the structure may be configured such that the induction heating part is made of a different material than the agitator, and the agitator is made of a material that shields the magnetic field to form a magnetic field shielding structure.

[0023] Alternatively, the agitator can be made of a material that shields the magnetic field, and the thermal conductivity of the agitator can be greater than that of the induction heating part.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] In this solution, the electromagnetic coil disk and the agitation component are designed to enable the electromagnetic coil disk to induce a stable geomagnetic field in the agitation component for induction heating, resulting in better stability and higher reliability of electromagnetic induction heating.

[0033] In this solution, by setting the structure of the agitator, multiple induction heating parts on the agitator form a large-area planar structure, while forming a first interval with a smaller coverage area. This allows the agitator to not only stably agitate the airflow to blow hot air into the cooking cavity, but also to form an electromagnetic coil plate to stably induce a geomagnetic field in the agitator for electromagnetic induction heating. The structure of the agitator prevents instability in the induction heating of the agitator by the electromagnetic coil plate, effectively improving the stability of electromagnetic induction heating of the agitator by the electromagnetic coil plate.

[0034] In this solution, the structure of the induction heating part and the structure and coverage area of ​​the first interval part are set to enable the agitator to form a large-area planar structure for induction heating of the electromagnetic coil disk, which effectively improves the stability and reliability of the electromagnetic coil disk induction heating of the agitator.

[0035] In this solution, the limited area of ​​the first interval allows the airflow to be effectively agitated by the agitator to form a blowing airflow structure. At the same time, it forms a large planar structure area on the agitator for electromagnetic induction heating, achieving a multi-functional effect for the agitator. The stability of the agitator in agitating the airflow and the stability of its own heating are also higher.

[0036] In this solution, the electromagnetic coil plate, the agitator, and the isolation component are arranged in a structural and positional configuration to isolate the electromagnetic coil plate from the agitator and the cooking cavity. This effectively facilitates cleaning for the user, eliminates the need for the heating element, and prevents oil stains and residue from adhering to the electromagnetic coil plate, greatly improving the ease of cleaning for the user.

[0037] In this solution, the isolation element and electromagnetic coil plate enable electromagnetic induction heating of the agitator. The agitator not only stirs the airflow but also generates its own heat, eliminating the need for the current heating element structure. This allows the electromagnetic coil plate to be isolated from the cooking cavity by the isolation element, making it easier for users to clean.

[0038] In this solution, users only need to clean the isolation components and the agitator components. The structure of the isolation components makes it easy for users to clean them directly, and the structure of the agitator components allows users to easily disassemble them for cleaning.

[0039] In this solution, the structure of the agitation component allows the drive component to install and remove the agitation component via magnetism, and simultaneously uses magnetic force to drive the rotation of the agitation component to agitate the flow. This facilitates the installation and removal of the agitation component by the user, and also makes it convenient for the user to maintain and clean the isolation component and the agitation component.

Detailed Implementation

[0046] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0047] Example: The air cooking device of this utility model, such as Figures 1 to 5As shown in the diagram, the air cooking device is mainly used to air-fry food, i.e., an air fryer. This solution, through the structure and positional distribution of the stirring component 5, the isolation component 4, and the electromagnetic coil plate 3, achieves good heating effect and heating stability of the stirring component 502 on the stirring component 5 by the electromagnetic coil plate 3. This effectively improves the stability and reliability of the induction heating of the stirring component 502 by the electromagnetic coil plate 3, and enhances the heating uniformity. At the same time, it is convenient for users to clean, as the electromagnetic coil plate 3 will not be contaminated with oil stains, food residues, etc., greatly improving the convenience of cleaning for users.

[0048] The air cooking device of this solution includes a main body 1, within which a receiving cavity is provided. The receiving cavity is an open structure with open sides, used to house a cooking pot 2. The cooking pot 2 is detachably installed in the receiving cavity for easy placement or removal by the user. The cooking pot 2 has a cooking chamber 201 for holding food for air frying. Air frying primarily achieves its effect by baking the food with hot airflow. An electromagnetic coil 3 is also provided on the main body 1 for electromagnetic induction heating, and is located above the cooking chamber 201. Separated from the cooking cavity 201, the electromagnetic coil plate 3 is separated from the cooking cavity 201 by an isolating member 4, which vertically isolates the two. This prevents oil stains and food residues splashed in the cooking cavity 201 from adhering to the electromagnetic coil plate 3. Instead, the oil stains and food residues splashed in the cooking cavity 201 will only splash onto the isolating member 4. Users can clean the isolating member 4 without having to clean the electromagnetic coil plate 3. At the same time, the structure of the electromagnetic coil plate 3 eliminates the current heating element structure, allowing the electromagnetic coil plate 3 to be isolated from the cooking cavity 201 by the isolating member 4, making it convenient for users to clean.

[0049] Regarding the structural components for generating the hot airflow, this design includes a flow-stirring assembly 5 within the main body 1. The flow-stirring assembly 5 heats the airflow to generate hot airflow, and the flow-stirring element 502 agitates the airflow to propel it into the cooking chamber 201. Specifically, the flow-stirring assembly 5 includes a drive element 501 and a flow-stirring element 502. The drive element 501 provides driving force and can be a motor. The flow-stirring element 502 heats the airflow to generate hot airflow and agitates the airflow to propel it into the cooking chamber 201. The driving component 501 is positioned above the isolation component 4 to provide driving force, and the agitator 502 is positioned below the isolation component 4, so that the driving component 501 and the agitator 502 form an isolation structure in the vertical direction. The agitator 502 can be detachably connected to the drive shaft on the driving component 501 to facilitate maintenance and cleaning of the agitator 502 by the user. Alternatively, a magnetic drive structure can be set between the driving component 501 and the agitator 502 to carry out transmission, which simplifies the transmission structure and makes it easier for the user to disassemble, maintain and clean the agitator 502.

[0050] The agitator 502, used for heating and agitating the airflow, includes multiple induction heating elements 5021. These elements heat the electromagnetic coil disk 3, generating heat that heats the airflow. The multiple induction heating elements 5021 are spaced apart in the annular direction of the agitator 5021, with a first spacer 5023 between adjacent elements. This first spacer 5023 allows airflow to enter the agitator 502, enabling it to agitate and blow out hot air. The flow is improved, and at least the upper surface of the induction heating part 5021 is configured to be planar in the horizontal direction. The planar structure of the induction heating part 5021 allows it to be better heated by the electromagnetic coil disk 3 through magnetic field induction. This makes the heating stability of the induction heating part 5021 better and the heating uniformity better, and makes the working stability of the electromagnetic coil disk 3 better. It also reduces the impact on the control module electrically connected to the electromagnetic coil disk 3, and makes the control module more stable. The planar structure of the induction heating part 5021 makes the induction of the electromagnetic coil disk 3 more consistent and stable. The induction heating part 5021 is heated more evenly, which in turn makes the heating effect of the airflow better and more uniform, resulting in a better effect and more uniformity of the generated hot airflow.

[0051] Among them, a downward-protruding agitator 5022 is provided on the lower end face of a single induction heating unit 5021 to agitate the airflow and blow it into the cooking cavity 201. The airflow is directly heated and radiated by the induction heating unit 5021 after entering the agitator 502. After the airflow enters, the agitator 5022 can agitate the airflow and blow it downward, so that the agitator 5022 blows the hot airflow toward the cooking cavity 201, so that the hot airflow can air-fry the food in the cooking cavity 201.

[0052] Specifically, the horizontal coverage area of ​​a single induction heating element 5021 is larger than that of a single agitator 5022 and also larger than that of a single first spacer 5023. This allows multiple induction heating elements 5021 to form a relatively large horizontal coverage area within the annular region of the agitator 502, creating a larger coverage area for induction heating by the electromagnetic coil disk 3. This improves the stability of electromagnetic induction heating of the induction heating elements 5021 and enhances the ability of multiple induction heating elements 5021 to conduct large-area airflow heating. The heating effect results in a higher temperature and better stability of the generated hot airflow. By creating multiple first intervals 5023 within the annular region of the agitator 502, the total area for airflow entry is relatively small. This allows the airflow entering the agitator 502 through the multiple first intervals 5023 to be better agitated by the multiple agitators 5022 to create a blowing airflow effect. At the same time, the airflow can be better heated during the agitation process, preventing the agitator 502 from being unable to heat the airflow in a timely and effective manner due to excessive airflow entering, thereby improving the heating effect of the agitator 502 on the airflow.

[0053] Optionally, a channel and structure for hot air discharge can be provided on the main body 1 of the device or the cooking pot 2, so that the hot air can be discharged after heating and air-frying the food in the cooking chamber 201, thereby forming the effect of hot air circulating in the main body 1 of the device.

[0054] To improve the stability and reliability of induction heating of the agitator 502 by the electromagnetic coil disk 3, this solution sets the total area of ​​the multiple induction heating parts 5021 in the horizontal direction to be greater than two-thirds of the total area of ​​the multiple induction heating parts 5021 and the multiple first interval parts 5023 in the horizontal direction. This achieves a relatively large coverage area in the horizontal direction of the multiple induction heating parts 5021 within the annular region of the agitator 502, forming a larger coverage area for induction heating by the electromagnetic coil disk 3. This improves the stability of electromagnetic induction heating of the induction heating parts 5021 and enhances the effect of large-area heating of the airflow by the multiple induction heating parts 5021, resulting in higher temperature and better stability of the generated hot airflow.

[0055] Alternatively, to improve the stability and reliability of the electromagnetic coil disk 3 in induction heating the agitator 502, the total area formed by the plurality of first interval portions 5023 in the horizontal direction is set to be less than one-third of the total area formed by the plurality of induction heating portions 5021 and the plurality of first interval portions 5023 in the horizontal direction. This results in a relatively small total area for airflow entry formed by the plurality of first interval portions 5023 within the annular region of the agitator 502, allowing the airflow entering the agitator 502 through the plurality of first interval portions 5023 to be better agitated by the plurality of agitators 5022 to create a blowing airflow effect. Simultaneously, during the agitation of the airflow, better... Heating the airflow prevents the agitator 502 from failing to heat the airflow effectively due to excessive airflow, thereby enhancing the heating effect of the agitator 502. Simultaneously, multiple induction heating elements 5021 within the annular region of the agitator 502 form a relatively large coverage area in the horizontal direction, allowing for induction heating by the electromagnetic coil disk 3. This improves the stability of electromagnetic induction heating of the induction heating elements 5021 and enhances the effect of large-area heating of the airflow by multiple induction heating elements 5021, resulting in higher and more stable hot airflow.

[0056] Alternatively, to improve the stability and reliability of induction heating of the agitator 502 by the electromagnetic coil disk 3, the horizontal coverage area of ​​a single induction heating part 5021 is set to be more than twice the horizontal coverage area of ​​a single agitator 5022. This achieves a relatively large horizontal coverage area formed by multiple induction heating parts 5021 within the annular region of the agitator 502, creating a larger coverage area for induction heating by the electromagnetic coil disk 3. This improves the stability of electromagnetic induction heating of the induction heating parts 5021 and enhances the effect of heating the airflow over a large area by multiple induction heating parts 5021. Furthermore, it allows for better and more concentrated heat transfer from a single induction heating part 5021 to a single agitator 5022, thereby increasing the area and effect of heating the airflow by the agitator 502, resulting in a higher temperature and better stability of the generated hot airflow.

[0057] Alternatively, to improve the stability and reliability of induction heating of the agitator 502 by the electromagnetic coil disk 3, the horizontal coverage area of ​​a single induction heating part 5021 is set to be more than twice the horizontal area of ​​a single first interval part 5023. This achieves a relatively large horizontal coverage area formed by multiple induction heating parts 5021 within the annular region of the agitator 502, creating a larger coverage area for induction heating by the electromagnetic coil disk 3. This improves the stability of electromagnetic induction heating of the induction heating parts 5021 and enhances the airflow control effect of multiple induction heating parts 5021. The large-area heating effect results in a higher temperature and better stability of the generated hot airflow. The multiple first intervals 5023 within the annular region of the agitator 502 create a relatively small total area for airflow entry. This allows the airflow entering the agitator 502 through the multiple first intervals 5023 to be better agitated by the multiple agitators 5022 to create a blowing airflow effect. At the same time, the agitator can better heat the airflow during the agitation process, preventing the agitator 502 from being unable to heat the airflow in a timely and effective manner due to excessive airflow entering, thereby improving the heating effect of the agitator 502 on the airflow.

[0058] To improve the stability and reliability of induction heating of the agitator 502 by the electromagnetic coil 3, this solution can be implemented by setting the total area of ​​multiple first intervals 5023 in the horizontal direction to be smaller than the coverage area of ​​a single induction heating element 5021 in the horizontal direction. This allows the multiple induction heating elements 5021 to form a relatively large coverage area in the horizontal direction, creating a larger coverage area for induction heating by the electromagnetic coil 3, thereby improving the stability of electromagnetic induction heating of the induction heating element 5021. At the same time, the relatively small total area of ​​the multiple first intervals 5023 in the horizontal direction allows for airflow entry, enabling the agitator 502 to heat itself stably while simultaneously heating the airflow, thus providing a stable supply of hot airflow and improving the air-frying cooking effect of the food.

[0059] Alternatively, to improve the stability and reliability of the electromagnetic coil disk 3 in induction heating the agitator 502, the total area of ​​the multiple first intervals 5023 in the horizontal direction is set to be smaller than the total area of ​​the multiple agitators 5022 in the horizontal direction. This allows the multiple induction heating units 5021 to form a relatively large coverage area in the horizontal direction, creating a larger coverage area for induction heating by the electromagnetic coil disk 3. This improves the stability of electromagnetic induction heating of the induction heating units 5021. At the same time, the airflow entering the agitator 502 through the multiple first intervals 5023 can be better agitated by the multiple agitators 5022 to create a blowing airflow effect. During the agitation of the airflow, the airflow can be heated more effectively, preventing the agitator 502 from being unable to heat the airflow in a timely and effective manner due to excessive airflow. This improves the heating effect of the agitator 502 on the airflow, resulting in a higher temperature and better stability of the generated hot airflow.

[0060] Alternatively, in order to improve the stability and reliability of the electromagnetic coil disk 3 in induction heating the agitator 502, the thickness of a single induction heating part 5021 in the vertical direction is set to be greater than the spacing distance of the first spacing part 5023 in the annular direction and less than the protrusion height of a single agitator 5022 in the protrusion direction.

[0061] In this design, to further enhance the effect of airflow entering the agitator 502, the first spacing portion 5023 can be configured such that the spacing distance in the annular direction gradually increases from the inside to the outside in the radial direction of the agitator 502. This allows the airflow near the outer ring of the agitator 502 to better enter the induction heating portion 5021 and then downwards into the agitator portion 5022. This results in the airflow gradually converging towards the inner ring of the agitator 502 and the agitator portion 5022 in the radial direction of the agitator 502, thereby enhancing the effect of the agitator 502 in agitating the airflow. At the same time, it enhances the heating effect of the airflow entering the agitator 502, enabling the agitator 502 to stably heat the airflow and blow the hot airflow into the cooking chamber 201, achieving a better air-frying cooking effect for the food.

[0062] Alternatively, to further enhance the effect of airflow entering the agitator 502 for blowing, this solution can be implemented by forming a second spacer 6 vertically between the upper end face of the induction heating part 5021 and the isolation member 4 for airflow entry. The vertical spacing of the second spacer 6 is set to be greater than the circumferential spacing of the first spacer 5023, thus forming a gap space between the upper end face of the induction heating part 5021 and the isolation member 4. This gap space is the second spacer 6. The second spacer 6 allows airflow to enter the first spacer 5023 on the agitator 502 better from top to bottom, enabling the airflow on the second spacer 6 to concentrate and enter the first spacer 5023, forming a structure where the airflow converges and enters the second spacer 6. This allows the airflow to enter the induction heating part 5021, be heated, and then enter the agitator 5022, achieving the effect of lifting the agitator 502 to blow hot airflow and simultaneously heating the airflow to generate hot airflow.

[0063] Optionally, the vertical spacing of the second interval 6 is set to be twice the circumferential spacing of the first interval 5023, so that the airflow can be better concentrated from the second interval 6 into the first interval 5023.

[0064] In this design, the electromagnetic coil disk 3 is equipped with a wire group 301. The wire group 301 can be configured as a tightly wound structure. The wire group 301 can be configured as a disc-shaped structure in the horizontal direction, or its cross-section can be rectangular and also disc-shaped in the horizontal direction. The disc-shaped structure of the wire group 301 can be circular, square, or polygonal as needed. The projection area formed by the vertical projection of the wire group 301 downwards is located on the induction heating part 5021, thereby achieving concentrated induction heating of the induction heating part 5021 by the wire group 301, thus improving the effect of concentrated heating of the induction heating part 5021. And / or, to further improve the effect of the electromagnetic coil disk 3 in induction heating the induction heating part 5021, and to further prevent the electromagnetic coil disk 3 from induction heating the stirring part 5022, in this design, the wire group 301 is configured to perform electromagnetic induction heating of the induction heating part 5021 and to further prevent the electromagnetic coil disk 3 from induction heating the stirring part 5022. The flow section 5022 has a non-heating structure, allowing the electromagnetic coil disk 3 to inductively heat only the induction heating section 5021 on the agitator 502. Due to the planar structure and large coverage area of ​​the induction heating section 5021, the electromagnetic coil disk 3 can stably inductively heat the induction heating section 5021, while the electromagnetic coil disk 3 cannot sense the agitator 5022. This allows the magnetic field of the electromagnetic coil disk 3 to be concentrated on the induction heating section 5021, achieving concentrated induction heating of the induction heating section 5021, while the agitator 5022 is not inductively heated by the electromagnetic coil disk 3. This improves the stability of the electromagnetic coil disk 3 in induction heating the agitator 502. Because of the structure of the agitator 5022, if it were induction heated by the electromagnetic coil disk 3, the stability of the magnetic field induction of the agitator 5022 by the electromagnetic coil disk 3 would be poor, which would also lead to poor working stability of the electromagnetic coil disk 3 and easy damage.

[0065] To further improve the effect of the electromagnetic coil disk 3 in induction heating the induction heating part 5021, and to further prevent the electromagnetic coil disk 3 from induction heating the stirring part 5022, this solution can provide a magnetic shielding part between the induction heating part 5021 and the stirring part 5022. This magnetic shielding part is configured to be thermally conductive. By providing the magnetic shielding part on the lower end surface of the induction heating part 5021 or the upper end surface of the stirring part 5022, the magnetic shielding part forms a structure that shields and isolates the magnetic field, thus achieving... The electromagnetic coil disk 3 cannot sense the stirring part 5022, so that the magnetic field of the electromagnetic coil disk 3 can be concentrated to sense the induction heating part 5021 to achieve concentrated induction heating of the induction heating part 5021. Due to the setting of the magnetic isolation part, the stirring part 5022 will not be induction heated by the electromagnetic coil disk 3. This improves the stability of the electromagnetic coil disk 3 in induction heating of the stirring part 502 and prevents the electromagnetic coil disk 3 from causing unstable induction heating of the stirring part 502 due to the structure of the stirring part 5022.

[0066] Understandably, because the agitator 5022 needs to agitate the airflow, its thickness in the annular direction is set to be relatively small. Therefore, a single agitator 5022 is generally a sheet-like structure, which can be a straight sheet or an arc-shaped sheet. Simultaneously, the protrusion height of a single agitator 5022 in the convex direction is set to be relatively large, greater than its thickness in the annular direction and greater than the thickness of the induction heating part 5021 in the vertical direction. Because of the sheet-like structure of the agitator 5022, if it is induction heated by the electromagnetic coil disk 3, it will... The instability of the electromagnetic coil disk 3 inducing the magnetic field of the agitator 5022 is poor, which in turn leads to poor working stability of the electromagnetic coil disk 3, making it prone to damage. At the same time, the heating effect of the agitator 5022 on the airflow is also poor, and it is impossible to stably generate hot airflow. Therefore, by setting the electromagnetic coil disk 3 to inductively heat the induction heating part 5021 while preventing induction heating of the agitator 5022, the stability and reliability of the agitator 502 being heated by electromagnetic induction can be effectively improved, and the heating effect of the agitator 502 on the airflow can be improved.

[0067] Alternatively, to further enhance the effect of the electromagnetic coil disk 3 in induction heating the induction heating part 5021, and to further prevent the electromagnetic coil disk 3 from induction heating the stirring part 5022, this solution involves setting the induction heating part 5021 and the stirring part 5022 to be made of different materials, and setting the stirring part 5022 to be made of a material that shields the magnetic field. For example, the induction heating part 5021 can be made of iron, and the stirring part 5022 can be made of aluminum or other materials that shield the magnetic field. This ensures that the agitator 5022 is not induced to heat by the electromagnetic coil 3, while only the induction heating part 5021 can be induced to heat by the electromagnetic coil 3. After being heated, the induction heating part 5021 can transfer heat to the agitator 5022, meaning that the induction heating part 5021 heats up on its own, and the agitator 5022 is heated by the heat transfer. This effectively improves the stability and reliability of the agitator 502 being heated by electromagnetic induction, and also enhances the effect of the agitator 502 in heating the airflow.

[0068] Alternatively, to further enhance the effect of the electromagnetic coil disk 3 in induction heating the induction heating part 5021, and to further prevent the electromagnetic coil disk 3 from induction heating the stirring part 5022, and to further enhance the effect of the induction heating part 5021 in heat transfer to the stirring part 5022, in this solution, the stirring part 5022 is made of a material that shields the magnetic field, and the thermal conductivity of the stirring part 5022 is greater than that of the induction heating part 5021. The stirring part 5022 is made of aluminum or other materials that shield the magnetic field, so that the stirring part 5022 will not be induction heated by the electromagnetic coil disk 3. Induction heating is performed only when the induction heating part 5021 can be sensed by the electromagnetic coil disk 3. At the same time, the thermal conductivity of the agitation part 5022 is set to be greater than that of the induction heating part 5021, so that the heat generated by the induction heating part 5021 can be transferred to the agitation part 5022 more quickly. That is, the induction heating part 5021 heats up itself, and the agitation part 5022 is heated by the heat transfer. This can effectively improve the stability and reliability of the agitation part 502 being heated by electromagnetic induction, and at the same time improve the effect of the agitation part 502 in heating the airflow.

[0069] To further enhance the heat transfer effect of the induction heating unit 5021 on the stirring unit 5022, this design provides a heat transfer unit at the junction of the stirring unit 5022 and the induction heating unit 5021. Specifically, a heat transfer unit is provided at the junction of the lower end face of the induction heating unit 5021 and the lower end face of the stirring unit 5022. The heat transfer unit is configured in a vertical direction with a gradually increasing cross-sectional area from bottom to top. This allows the heat from the induction heating unit 5021 to be better transferred downwards to the stirring unit 5022. At the same time, it also strengthens the structural strength of the stirring unit 5022 and improves the stability of the rotational motion of the stirring unit 5022 driven by the induction heating unit 5021.

[0070] Preferably, the height of the heat transfer section in the vertical direction is greater than the thickness of the agitator 5022 in the annular direction and less than the thickness of the induction heating section 5021 in the vertical direction. This allows the heat from the induction heating section 5021 to be better transferred downwards to the agitator 5022, thereby enabling the agitator 502 to better heat and agitate the airflow. And / or, preferably, the thermal conductivity of the heat transfer section is less than the thermal conductivity of the agitator 5022 and greater than or equal to the thermal conductivity of the induction heating section 5021. This allows the heat from the induction heating section 5021 to be better transferred to the heat transfer section, resulting in better heat transfer. By setting the thermal conductivity of the three components, the heat from the induction heating section 5021 is better transferred to the agitator 5022, thereby enabling the agitator 502 to better heat and agitate the airflow.

[0071] In this design, to improve the heat transfer effect of the induction heating unit 5021 on the stirring unit 5022, the stirring unit 5022 can be positioned at the center of the lower end face of the induction heating unit 5021. This allows the induction heating unit 5021 to form a shielding structure over the stirring unit 5022 in the vertical direction from top to bottom. This results in better heat transfer at the lower end face of the induction heating unit 5021, enabling the heat from the induction heating unit 5021 to be effectively transferred. The heat is concentrated and transferred to the agitator 5022 at the middle position of the lower end face, thereby achieving the effect of raising the agitator 5022 to heat the airflow. At the same time, the induction heating part 5021 is configured to shield the agitator 5022 in the vertical direction from top to bottom, so that the heat on the induction heating part 5021 and the agitator 5022 can be better concentrated and radiated downward to heat the airflow, and the heat is not easily radiated upward, thereby achieving the effect of raising the agitator 502 to heat the airflow in the vicinity below it.

[0072] Alternatively, to enhance the heat transfer effect of the induction heating unit 5021 on the agitation unit 5022, the individual induction heating unit 5021 and the corresponding individual agitation unit 5022 can be configured in a T-shape. In this case, the cross-section is mainly T-shaped. The T-shape structure can better transfer the heat from the induction heating unit 5021 to the agitation unit 5022. At the same time, it can better concentrate and radiate the heat from the induction heating unit 5021 and the agitation unit 5022 downward to heat the airflow. The heat is not easily radiated upward, thereby achieving the effect of enhancing the agitation unit 502 to heat the surrounding airflow.

[0073] Alternatively, to enhance the heat transfer effect of the induction heating unit 5021 on the agitation unit 5022, the individual induction heating unit 5021 and the corresponding individual agitation unit 5022 can be configured in a Г-shaped structure. In this case, the cross-section is mainly Г-shaped. The Г-shaped structure can better transfer the heat of the induction heating unit 5021 to the agitation unit 5022. At the same time, it can better concentrate and radiate the heat on the induction heating unit 5021 and the agitation unit 5022 downward to heat the airflow, thereby enhancing the agitation unit 502 to heat the surrounding airflow.

[0074] In this design, the driving component 501 in the agitation assembly 5 drives the agitation component 502 to rotate. The driving component 501 has a first magnetic component 5011 located on the inner ring or center of the electromagnetic coil disk 3. The agitation component 502 has a second magnetic component 5024. Both the first and second magnetic components 5011 and 5024 are magnetic. The first and second magnetic components 5011 and 5024 are arranged in a vertically corresponding configuration, allowing them to magnetically attract each other. The first magnetic component 5011 is configured to magnetically mount the second magnetic component 5024 onto the isolation component 4, thus creating a vertically isolated structure between them, preventing them from contacting each other. When the second magnetic component 5024 is installed on the isolation component 4, it is attracted to the isolation component 4 by the magnetic force of the first magnetic component 5011, thus achieving the installation effect. The magnetic attraction of the first magnetic component 5011 and the second magnetic component 5024 can pass through the isolation component 4 to achieve the magnetic attraction structure between them. By setting the magnetic structure, it is convenient to install or remove the agitator component 5 more easily and quickly. Users can quickly and easily remove the agitator component 502 for maintenance and cleaning, and can also quickly and easily install the agitator component 502 in place. After removing the agitator component 502, users can also easily clean the oil stains and residues splashed on the isolation component 4, effectively reducing the difficulty of cleaning for users. There is no need to clean the electromagnetic coil plate 3. The structure of the isolation component 4 isolates the electromagnetic coil plate 3 from the cooking cavity 201, which can effectively prevent oil stains and residues from splashing onto the electromagnetic coil plate 3.

[0075] The driving member 501 is configured to achieve synchronous rotation between the first magnetic member 5011 and the second magnetic member 5024 through the magnetic attraction between them. Specifically, when the driving member 501 drives the first magnetic member 5011 to rotate, the first magnetic member 5011 drives the second magnetic member 5024 to rotate synchronously via magnetic force. The second magnetic member 5024 then drives the agitator 502 to rotate synchronously. When the driving member 501 starts working and drives the first magnetic member 5011 to rotate, the magnetic attraction between the first magnetic member 5011 and the second magnetic member 5024 passes through the isolation member 4 to achieve synchronous rotation. This results in the second magnetic member 5024 rotating on the isolation member 4. 24 drives the agitator 502 to rotate. During the rotation, the agitator 502 agitates the airflow and blows it into the cooking cavity 201. At the same time, the induction heating part 5021 on the agitator 502 is induction heated by the electromagnetic coil disk 3, so that the induction heating part 5021 heats up itself. After the induction heating part 5021 heats up, it can also transfer the heat to the agitator 5022. The induction heating part 5021 and the agitator 5022 together heat the airflow near the agitator 502. That is, the agitator 502 heats up itself to heat the airflow and generate hot airflow. The agitator 502 is heated and generates hot airflow while rotating, so as to provide hot airflow into the cooking cavity 201 and achieve the effect of air-frying the food in the cooking cavity 201.

[0076] Optionally, the driving component 501 is a motor, and the first magnetic component 5011 is mounted on the motor shaft.

[0077] The magnetic core attraction between the first magnetic component 5011 and the second magnetic component 5024 is greater than the gravity of the second magnetic component 5024, so that the second magnetic component 5024 can be driven to rotate by the magnetic attraction when it is installed on the isolation component 4 by the magnetic attraction.

[0078] For any aspects not covered in this solution, existing technologies can be used or referenced.

[0079] Working Principle: The air cooking device of this solution uses structures such as an electromagnetic coil 3, an isolator 4, and a stirring component 5. The isolator 4 separates the electromagnetic coil 3 from the cooking chamber 201, preventing oil stains and residues from splattering onto the electromagnetic coil 3 during air frying. This solves the problem of oil stains and residues splattering onto the heating element and being difficult to clean in existing air cooking devices. Simultaneously, the structure of the stirring component 502, through the arrangement and placement of the induction heating elements 5021 and the stirring elements 5022, as well as the size of their coverage area, allows multiple induction heating elements 5021 on the stirring component 502 to form a large-area planar structure, while simultaneously forming a smaller-area first interval 5023. The agitator 502 not only stably agitates the airflow to blow hot air into the cooking cavity 201, but also enables the electromagnetic coil disk 3 to form a stable geomagnetic field induction for electromagnetic induction heating of the agitator 502. The structure of the agitator 5022 prevents instability in the induction heating of the agitator 502 by the electromagnetic coil disk 3. At the same time, the structure of the electromagnetic coil disk 3 and the agitator 502 eliminates the need for a heating tube structure, enabling the agitator 502 to form a self-heating structure through electromagnetic induction. The agitator 502 agitates the airflow while heating it, generating hot airflow to achieve the air-frying cooking effect for the food. It also makes it convenient for users to clean the isolation piece 4 and the agitator 502.
