It should be apparent that the described embodiments are only some embodiments of the present application, and not all embodiments.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1-2, the present embodiment provides an air fryer 100, wherein the air fryer 100 is a cooking appliance for heating food using hot air. Air fryer 100 may also be an air cooking device such as an air oven, a fry and bake station, or the like.

Air fryer 100 comprises housing 10, wind wheel 20, and drive mechanism 30, both wind wheel 20 and drive mechanism 30 being loadable into housing 10.

The casing 10 is provided with a heat dissipation space 11 and an air outlet 12, and the heat dissipation space 11 is communicated with the air outlet 12. The outlet 12 may be configured as an outlet with different directions according to the structure type of the housing 10, for example, the outlet 12 may be configured as a bottom outlet, a side outlet, a top outlet, and so on.

For example, the housing 10 may be used as a bottom housing of an air fryer, and the outlet 12 may be used as a bottom outlet, a side outlet, etc. For another example, the housing 10 may be a top housing of an air fryer, and the outlet 12 may be a top outlet, a side outlet, etc.

The wind wheel 20 is rotatably positioned within the housing 10. The wind wheel 20 is capable of sucking air in its own axial direction and delivering the air radially outward. The wind wheel 20 has a first wind inlet side 21, a second wind inlet side 22 and a wind outlet side 23, the first wind inlet side 21 and the second wind inlet side 22 are located on opposite sides of the wind wheel 20, and the wind outlet side 23 faces the heat dissipation space 11, so that the wind wheel 20 can blow air sucked from the first wind inlet side 21 and the second wind inlet side 22 to the heat dissipation space 11 through the wind outlet side 23 during the rotation process.

The driving mechanism 30 is connected to the wind wheel 20 and is used for driving the wind wheel 20 to rotate. For example, the drive shaft 31 of the drive mechanism 30 is fitted to the wind rotor 20 so that the wind rotor 20 can be rotated by the drive shaft 31. The driving mechanism 30 may be a driving motor, the driving shaft 31 of the driving mechanism 30 may be an output shaft of the driving motor, and the driving shaft 31 of the driving mechanism 30 may also be another shaft in transmission connection with the output shaft of the driving motor.

The drive mechanism 30 is located on the first intake side 21. For example, the main structure 32 of the driving mechanism 30 may be located on the first air inlet side 21 of the wind wheel 20, and the driving shaft 31 of the driving mechanism 30 may be connected to the wind wheel 20. Since the main structure 32 mainly generates heat during the operation of the driving mechanism 30, the wind wheel 20 can suck the heat generated by the driving mechanism 30 into the wind wheel 20 along with the air from the first air inlet side 21 and blow the heat to the heat dissipation space 11 from the air outlet side 23 during the rotation process, so that the heat can be discharged out of the housing 10 through the air outlet 12. In this way, the wind wheel 20 can dissipate heat of the driving mechanism 30, which helps to ensure the stability of the operation of the driving mechanism 30.

In some embodiments, air fryer 100 may further comprise a heating assembly 40, heating assembly 40 comprising an electromagnetic coil disk 41 and a magnetically conductive heating element 42, both electromagnetic coil disk 41 and magnetically conductive heating element 42 may be located within housing 10.

The electromagnetic coil panel 41 is located on the second air intake side 22 of the wind wheel 20. The electromagnetic coil disk 41 is capable of generating an alternating magnetic field by the alternating current.

The magnetic conduction heating element 42 is made of magnetic conduction material. The magnetic conduction heating element 42 is opposite to the electromagnetic coil panel 41, the magnetic conduction heating element 42 can cut alternating magnetic lines of force in a magnetic field generated by the electromagnetic coil panel 41 to generate vortex current, the vortex current enables carriers in the magnetic conduction heating element 42 to move randomly at a high speed, and the carriers collide and rub with atoms to generate heat energy, so that the magnetic conduction heating element 42 generates heat. Thus, the heat generated by the magnetic conduction heating element 42 is helpful for heating the food material.

In some embodiments, the magnetic heat generating member 42 may be an iron magnetic heat generating member, for example, the magnetic heat generating member 42 may be made of pig iron, and for example, the magnetic heat generating member 42 may be made of iron alloy such as steel, cast iron, and the like. So, help the magnetic conduction to generate heat piece 42 and have good magnetic conductivity, the magnetic conduction of being convenient for generates heat piece 42 and can generate heat and manufacturing cost is lower under the alternating magnetic field effect of electromagnetic coil panel 41.

In addition, since the electromagnetic coil panel 41 generates heat under the influence of the magnetic conductive heating element 42, by positioning the electromagnetic coil panel 41 on the second air inlet side 22 of the wind wheel 20, heat generated by the electromagnetic coil panel 41 during the rotation of the wind wheel 20 can be drawn into the wind wheel 20 along with air from the second air inlet side 22 and blown to the heat dissipation space 11 from the air outlet side 23, so that the heat can be discharged out of the housing 10 through the air outlet 12. Therefore, the wind wheel 20 can radiate heat for the electromagnetic coil panel 41, which helps to avoid the electromagnetic coil panel 41 from generating too much heat, thereby helping to ensure the working stability of the electromagnetic coil panel 41.

The magnetic conduction heating piece 42 is positioned on one side, deviating from the wind wheel 20, of the electromagnetic coil panel 41, so that the positions of the magnetic conduction heating piece 42, the electromagnetic coil panel 41 and the wind wheel 20 are reasonably arranged, heat loss of the magnetic conduction heating piece 42 caused by the fact that the wind wheel 20 takes away heat of the magnetic conduction heating piece 42 is reduced, and therefore the heating effect of the magnetic conduction heating piece 42 is guaranteed.

Referring to fig. 2 and 3, the first air inlet side 21 and the second air inlet side 22 of the wind wheel 20 can be designed to have different air inlet amounts.

For example, the wind wheel 20 may include a first plate 24, a second plate 25, and a plurality of guide vanes 26, where the first plate 24 is opposite to the second plate 25, and the plurality of guide vanes 26 are connected between the first plate 24 and the second plate 25. The first panel 24 can face the first air inlet side 21 and the first panel 24 can be opposite the main structure 32 of the drive mechanism 30. The second plate body 25 may face the second air intake side 22, and the second plate body 25 may be opposite to the electromagnetic coil panel 41.

In the present application, the term "plurality" means greater than or equal to two, for example, the number of guide vanes 26 may be two, three, four, five, six, seven, or other numbers.

The first plate 24 and the second plate 25 may be provided with air inlet holes 27. For example, the first plate 24 may be provided with one or more air inlet holes 27, so that heat around the driving mechanism 30 may enter the wind wheel 20 through the air inlet holes 27 of the first plate 24. For another example, the second plate 25 may be provided with one or more air inlet holes 27, so that heat around the electromagnetic coil panel 41 may enter the wind wheel 20 along with air through the air inlet holes 27 of the second plate 25.

The area of the air inlet through holes 27 of the second plate 25 can be larger than that of the air inlet through holes 27 of the first plate 24, so that the air inlet amount of the wind wheel 20 on the second air inlet side 22 is larger than that on the first air inlet side 21, which is beneficial to better radiating the electromagnetic coil panel 41 and ensures the working stability of the electromagnetic coil panel 41. The area of the air inlet through holes 27 of the second plate 25 being larger than the area of the air inlet through holes 27 of the first plate 24 means that the sum of the areas of all the air inlet through holes 27 of the second plate 25 is larger than the sum of the areas of all the air inlet channels of the first plate 24. For example, in the embodiment of fig. 3, the second plate 25 has one air inlet 27, the first plate 24 has three air inlet 27, and the area of the air inlet 27 of the second plate 25 is larger than the sum of the areas of the three air inlet channels 27 of the first plate 24.

The wind wheel 20 may be connected to the driving mechanism 30 through the first plate 24. For example, the first plate 24 may include a plate body 241 and a rotation shaft assembling portion 242, and the plate body 241 and the rotation shaft assembling portion 242 are connected. The plate body 241 may be opposite to the second plate 25, and the guide vanes 26 may be connected between the plate body 241 and the second plate 25. The panel body 241 faces the first air inlet side 21, and the first panel 24 can be opposite to the main structure 32 of the driving mechanism 30.

The rotation shaft assembling portion 242 may be assembled to the driving shaft 31 of the driving mechanism 30 so that the driving mechanism 30 may rotate the wind wheel 20.

The shaft mounting portion 242 and the driving mechanism 30 may be engaged in a shaft hole manner. For example, the driving shaft 31 of the driving mechanism 30 may be inserted into the shaft mounting portion 242, so that the wind wheel 20 may be sleeved on the driving shaft 31.

For example, the drive shaft 31 includes a first shaft segment 311 and a second shaft segment 312 connected, the first shaft segment 311 may be generally cylindrical, and the first shaft segment 311 may be connected to the body structure 32 of the drive mechanism 30. The second shaft section 312 may be connected to an end of the first shaft section 311 facing away from the main structure 32 of the driving mechanism 30, and the second shaft section 312 may have a substantially elliptic cylinder shape, a semi-cylindrical shape, a prismatic shape, etc. Correspondingly, the rotating shaft assembling portion 242 may be provided with a through hole adapted to the second shaft section 312, so that the second shaft section 312 is inserted into the through hole of the rotating shaft assembling portion 242, and the driving shaft 31 can drive the wind wheel 20 to rotate.

In addition, because the wind wheel 20 is connected with the driving mechanism 30 through the first plate body 24, the second plate body 25 is prevented from being provided with a structure matched with the driving mechanism 30 and occupying the position of the air inlet through hole 27 of the second plate body 25, the area of the air inlet through hole 27 of the second plate body 25 can be designed to be larger, and the heat dissipation effect of the wind wheel 20 on the electromagnetic coil panel 41 can be further improved.

The plate body 241 may have a plurality of air inlet holes 27, and the plurality of air inlet holes 27 may surround the rotating shaft assembling portion 242. In this way, the plurality of air inlet through holes 27 helps to increase the air inlet amount of the wind wheel 20 on the first air inlet side 21.

The rotating shaft assembling portion 242 may be convexly disposed on one side of the plate body 241 facing the second plate body 25, since the air flowing speed of the air closer to the rotation axis of the wind wheel 20 is slower during the rotation of the wind wheel 20, and the rotating shaft assembling portion 242 helps to reduce the air staying around the rotation axis of the wind wheel 20 by occupying a certain space position of the wind wheel 20 around the rotation axis, so that the wind wheel 20 can better convey the air sucked from the second air inlet side 22 to the air outlet side 23.

The rotating shaft assembling portion 242 may be provided with a wind guide surface 2421, the wind guide surface 2421 surrounds the rotating axis of the rotating shaft assembling portion 242, and the wind guide surface 2421 faces the guide vane 26. The distance between the air guide surface 2421 and the guide vane 26 may increase along the direction from the second plate 25 to the plate body 241. In this way, the air guide surface 2421 can guide the airflow entering the wind wheel 20 from the second air inlet side 22 to flow along the radial direction of the wind wheel 20, which helps to increase the flow rate of the airflow. The air guide surface 2421 may be an inclined surface or an arc surface.

In some embodiments, the magnetic heat generating member 42 may be an iron magnetic member, for example, the magnetic heat generating member 42 may be made of pig iron, and for example, the magnetic heat generating member 42 may be made of iron alloy such as steel, cast iron, and the like. Therefore, the magnetic conductive heating element 42 has good magnetic conductivity, the magnetic conductive heating element 42 can generate heat under the action of the alternating magnetic field of the electromagnetic coil panel 41, and the manufacturing cost is low.

In some embodiments, the shape of the magnetic conductive heating element 42 is adapted to the cross-sectional shape of the pot, for example, the magnetic conductive heating element 42 may be a substantially disk-shaped magnetic conductive plate, which helps the magnetic conductive heating element 42 to be adapted to the pot with a substantially circular cross-section and the substantially annular electromagnetic coil panel 41, which helps the magnetic conductive heating element 42 to generate more heat.

Referring to fig. 4, the thickness of the magnetic conductive heating element 42 may be D1, and D1 is approximately 1mm to 3mm. For example, D1 may be approximately 1mm, 1.2mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm, 3mm, or any value between any two of the foregoing.

Thus, the thickness of the magnetic conduction heating element 42 is not too thin, which reduces the strength of the magnetic conduction heating element, so that the magnetic conduction heating element 42 is not easy to bend and deform, and the magnetic conduction heating element 42 is helpful to generate heat sufficiently. The thickness of the magnetic conduction heating element 42 is not too thick, which results in the overweight of the whole magnetic conduction heating element 42. Through reasonable design, the thickness of the magnetic conduction heating piece 42 is approximately 1 mm-3 mm, which is beneficial to ensuring that the magnetic conduction heating piece 42 has better strength and proper weight.

The distance between the magnetic conduction heating element 42 and the electromagnetic coil panel 41 is D2, and D2 can be approximately 6 mm-12 mm. For example, D2 may be approximately 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 11mm, 11.5mm, 12mm, or any value between any two of the foregoing.

Therefore, the distance between the magnetic conductive heating element 42 and the electromagnetic coil panel 41 is not too small, so that the magnetic conductive heating element 42 and the electromagnetic coil panel 41 are too close to each other, which is helpful for reducing the heat generated by the magnetic conductive heating element 42 to be conducted to the electromagnetic coil panel 41, thereby being helpful for ensuring the working stability of the electromagnetic coil panel 41. The distance between the magnetic conduction heating element 42 and the electromagnetic coil panel 41 is not too large, so that the position of the magnetic conduction heating element 42 is too far away from the position of the electromagnetic coil panel 41, which is beneficial to the magnetic conduction heating element 42 to better induce the alternating magnetic field of the electromagnetic coil panel 41 and generate heat, thereby being beneficial to ensuring the heating efficiency of the magnetic conduction heating element 42. By reasonably arranging the distance between the magnetic conduction heating element 42 and the electromagnetic coil panel 41 to be approximately 6 mm-12 mm, the magnetic conduction heating element 42 is ensured to have good heating efficiency, and the thermal influence of the magnetic conduction heating element 42 on the electromagnetic coil panel 41 is reduced.

In some embodiments, the magnetic conduction heating element 42 may be an iron fan, and the magnetic conduction heating element 42 is rotatably disposed on one side of the electromagnetic coil panel 41, so that the heat generated by the rotation of the magnetic conduction heating element 42 can form a hot air flow, thereby achieving the heating effect of the air fryer 100 to form a hot air flow.

For example, in the embodiment shown in fig. 1, the fryer body 300 is disposed below the magnetic conductive heating element 42, so that the fryer body 300 receives the hot airflow blown from the magnetic conductive heating element 42 and heats the food material.

The magnetic conductive heating element 42 can also blow out the hot air from bottom to top, and for example, in the embodiment of fig. 5, the fryer body 300 is disposed below the magnetic conductive heating element 42, so that the fryer body 300 receives the hot air blown out from bottom to top by the magnetic conductive heating element 42 to heat the food material.

The magnetic conductive heating element 42 can be connected to the driving mechanism 30, so that the driving mechanism 30 can drive the magnetic conductive heating element 42 to rotate.

Referring to fig. 2 and 4, in some embodiments, the heating assembly 40 may further include a heating fan 43, the heating fan 43 is disposed opposite to the magnetic conductive heating element 42, and the driving mechanism 30 is connected to the heating fan 43 and is configured to drive the heating fan 43 to rotate, so that heat generated by the magnetic conductive heating element 42 can be formed into a hot air flow during the rotation of the heating fan 43, and a heating effect of forming the hot air flow by the air fryer 100 can also be achieved.

In some embodiments, the magnetic heat-generating member 42 is spaced apart from the heating fan 43, and the magnetic heat-generating member 42 generates heat and then conducts the heat to the heating fan 43 through air. The mode that magnetic conduction heating element 42 and heating fan 43 set up alone is favorable to the manufacturing of both, has promoted production efficiency. In addition, two spare parts set up alone, also are convenient for overhaul alone and change.

In some embodiments, the magnetic heat-conducting heating member 42 is fixedly connected with the heating fan 43 to conduct heat to the heating fan 43. For example, the magnetic heat generating member 42 may be mounted to the heating fan 43 by a fastening member such as a bolt. In this embodiment, the magnetic heat-conducting heating element 42 and the heating fan 43 can transmit heat via the connecting element, and the heat transmission efficiency is improved due to the closer distance between the two elements.

Specifically, in the above embodiment, the two may be fixed integrally by welding, screwing, snapping, or the like, or may be fixed integrally by a fastener such as a screw or a rivet.

Specifically, in the above embodiment, the heating fan 43 may include a plate body 431 and fan blades 432, the number of the fan blades 432 may be plural, and the plurality of fan blades 432 may be connected to form an integrated structure, and the integrated structure is connected to the plate body 431.

The heating fan 43 may include only the blades 432, and the blades 432 are independently connected to the plate 431. For example, the number of blades 432 may be two, three, four, five, six, seven, or other numbers. In the present embodiment, the number of blades 432 is seven.

Referring to FIG. 6, the thickness of the fan blade 432 can be D3, wherein D3 is approximately 1mm to 3mm. For example, D3 may be approximately 1mm, 1.2mm, 1.4mm, 1.5mm, 1.6mm, 1.8mm, 2mm, 2.2mm, 2.4mm, 2.5mm, 2.6mm, 2.8mm, 3mm, or any value between any two of the foregoing.

Thus, the thickness of the fan blade 432 is not too thin, which reduces the strength of the fan blade 432, so that the fan blade 432 is not easily bent and deformed, thereby ensuring that the heating fan 43 stably supplies air volume. The thickness of the fan blades 432 is not so thick that the entire weight of the heating fan 43 is too heavy, which contributes to the reduction of the load of the driving structure, and thus contributes to the reduction of noise and the increase of the air volume. By reasonably designing the thickness of the fan blade 432 to be approximately 1 mm-3 mm, the fan blade 432 is facilitated to be guaranteed to have better strength and proper weight.

The thickness of the fan blade 432 and the thickness of the magnetic conductive heating element 42 can be substantially the same, so that the heating fan 43 can be conveniently processed and molded, and the manufacturing difficulty of the heating fan 43 can be simplified.

In some embodiments, the magnetic conductive heating element 42 and the heating fan 43 may be an integrally formed structure, the magnetic conductive heating element 42 may serve as a plate 431 of the heating fan 43, and the fan blade 432 may be connected to the magnetic conductive heating element 42.

Specifically, the heating fan 43 may be made of a metal material, so that the magnetic conductive heating element 42 can conduct the generated heat to the heating fan 43, and the heating fan 43 can also generate heat, thereby facilitating to improve the heating effect of the heating fan 43.

The heating fan 43 may be an iron fan, for example, the heating fan 43 may be made of pig iron, and for example, the heating fan 43 may be made of iron alloy such as steel and cast iron. Thus, the heating fan 43 can be easily formed, which helps to simplify the manufacturing difficulty and cost of the heating fan 43. The heating fan 43 and the magnetic conductive heating element 42 may be made of the same material.

In some embodiments, the material of the magnetic heat-generating member 42 and the material of the heating fan 43 may be the same, for example, the magnetic heat-generating member 42 and the heating fan 43 may both be of a ferrous structure. Therefore, the manufacturing cost of the magnetic conduction heating element 42 and the heating fan 43 is reduced, the combined parts are made of iron materials, heat can be generated and transferred, the number of parts is reduced, the manufacturing process is simplified, and the production efficiency of the air fryer 100 is improved.

In some embodiments, the fan blade 432 may be located on a side of the magnetic heat-conducting member 42 away from the electromagnetic coil panel 41, which facilitates designing a distance between the electromagnetic coil panel 41 and the magnetic heat-conducting member 42 without considering the influence of the height of the fan blade 432, and facilitates simplifying the arrangement between the electromagnetic coil panel 41 and the heating fan 43. In other embodiments, the fan blade 432 may be located on the side of the magnetic conductive heating element 42 facing the electromagnetic coil panel 41.

Referring to fig. 1 and 2, the heating fan 43 may also be driven by the driving mechanism 30. For example, the driving shaft 31 of the driving mechanism 30 is inserted into the electromagnetic coil panel 41, and the wind wheel 20 and the heating fan 43 are both mounted on the driving shaft 31. So, because wind wheel 20 and heating fan 43 adopt same actuating mechanism 30 to drive, help improving actuating mechanism 30's utilization ratio, still help actuating mechanism 30 can drive wind wheel 20 and heating fan 43 rotation in step for when heating fan 43 carries out heating work, wind wheel 20 can in time be the stability of electromagnetic coil panel 41 work in order to guarantee for electromagnetic coil panel 41 heat dissipation.

The driving shaft 31 may also be inserted through the heating fan 43, so that the heating fan 43 can be sleeved on the driving shaft 31. For example, the heating fan 43 may be provided with a through hole adapted to the second shaft section 312, so that the second shaft section 312 is disposed through the through hole of the heating fan 43, and the driving shaft 31 can drive the heating fan 43 to rotate.

Air fryer 100 may be provided with a locking structure to prevent heating fan 43 from disengaging drive shaft 31. For example, air fryer 100 may further include retaining member 60, retaining member 60 being removably mounted to drive shaft 31 and located on a side of heating fan 43 facing away from solenoid coil disk 41. In this manner, the locking member 60 can restrain the heating fan 43 so that the heating fan 43 does not come off the drive shaft 31 in the axial direction of the drive shaft 31, which contributes to improving stability during rotation of the heating fan 43.

In addition, because the retaining member 60 is detachably connected to the driving shaft 31, the retaining member 60 can be detached from the driving shaft 31, and then the heating fan 43 can be detached from the driving shaft 31, so that the user can clean the heating fan 43 conveniently, and the use scene of the air fryer 100 can be enriched.

The locking member 60 and the driving shaft 31 may be detachably coupled by means of a screw-thread coupling. For example, the locking element 60 can be provided with an internal thread and the end of the drive shaft 31 facing away from the main structure 32 can be provided with an external thread, which can be adapted to the internal thread of the locking element 60, so that the connection of the locking element 60 and the drive shaft 31 can be realized by means of the internal thread and the external thread.

Air fryer 100 may also be provided with a retaining structure to improve the stability of wind wheel 20 and heating fan 43 assembly to drive shaft 31. For example, air fryer 100 may further include a bushing 70, and bushing 70 may be sleeved around drive shaft 31 and against wind wheel 20 and heating fan 43. In this way, the bushing 70 helps the wind wheel 20 and the heating fan 43 to maintain their positions, so that the wind wheel 20 and the heating fan 43 are not easily moved in the axial direction of the driving shaft 31.

For example, the shaft sleeve 70 may abut against the surface of the wind wheel 20 facing away from the first shaft section 311, so that the wind wheel 20 cannot slide towards the shaft sleeve 70 along the axial direction of the driving shaft 31, and the first shaft section 311 also restricts the wind wheel 20 from sliding towards the first shaft section 311 along the axial direction of the driving shaft 31. For another example, the shaft sleeve 70 may abut against a surface of the heating fan 43 away from the locking member 60, so that the heating fan 43 cannot slide toward the shaft sleeve 70 along the axial direction of the driving shaft 31, and the locking member 60 also prevents the heating fan 43 from sliding toward the locking member 60 along the axial direction of the driving shaft 31, thereby improving the stability of the wind wheel 20 and the heating fan 43 assembled on the driving shaft 31.

In some embodiments, the heat dissipation space 11 of the housing 10 may be defined by a strip of the housing 10. For example, the casing 10 may further include a first strip 16 and a second strip 17, the first strip 16 is located on the first air inlet side 21, the second strip 17 is located on the second air inlet side 22, and the heat dissipation space 11 is defined between the first strip 16 and the second strip 17. The first support plate 16 is provided with a first through hole 161, the second support plate 17 is provided with a second through hole 171, and the first through hole 161 and the second through hole 171 are both communicated with the heat dissipation space 11. In this manner, heat generated by the drive mechanism 30 can enter the heat dissipation space 11 from the first through hole 161, and heat generated by the electromagnetic coil disk 41 can enter the heat dissipation space 11 from the second through hole 171.

Air fryer 100 may further comprise a panel 80, panel 80 may be mounted to housing 10, for example, panel 80 may be mounted within housing 10.

The panel 80 may be located between the electromagnetic coil panel 41 and the magnetic conductive heating element 42, and the panel 80 may shield the electromagnetic coil panel 41. In this way, the panel 80 helps to separate the heat transferred to the electromagnetic coil panel 41 from the magnetic conductive heating element 42, reduces the thermal influence of the magnetic conductive heating element 42 on the electromagnetic coil panel 41, and helps to ensure the stability of the operation of the electromagnetic coil panel 41.

In addition, since the panel 80 shields the electromagnetic coil panel 41, the panel 80 can prevent food materials or oil droplet dirt of the heating fan 43 from splashing and adhering to the electromagnetic coil panel 41, and a large amount of oil stain dirt adhering to the electromagnetic coil panel 41 is avoided. When the heating fan 43 is removed from the drive shaft 31 of the drive mechanism 30, the panel 80 can be cleaned, which helps to reduce the difficulty of cleaning the air fryer 100.

In addition, after the heating fan 43 is detached from the driving shaft 31, the panel 80 can also be used as a bearing panel of an iron pan, for example, when the iron pan is placed at the original position of the heating fan 43, the iron pan can also generate heat under the action of the alternating magnetic field of the electromagnetic coil panel 41, so that the iron pan can be directly placed on the panel 80 for cooking. For example, as shown in FIG. 7, iron pan 400 and air fryer 100 may be combined into an electric fryer; for example, as shown in FIG. 8, iron pan 400 may be combined with air fryer 100 in combination with a steam rack 500 into an electric steamer. Thus, the use scene of the air fryer 100 is expanded, and the use frequency of the air fryer 100 is improved.

In addition, when the heating fan 43 is re-assembled to the driving shaft 31, the air fryer 100 may continue to generate the hot air current by the heating fan 43.

In some embodiments, the housing 10 may include a fixed sidewall 15, and the edge 81 of the panel 80 may abut against the inner side of the fixed sidewall 15, and the panel 80 and the fixed sidewall 15 are combined to form a closed state, so that the panel 80 better blocks oil droplet dirt from entering the electromagnetic coil panel 20.

Referring to fig. 4, the panel 80 may be spaced apart from the magnetic heat-conducting heating element 42, so as to avoid friction between the heating fan 43 and the panel 80 during rotation to increase the load of the driving mechanism 30 and generate larger noise, and to reduce heat transfer from the magnetic heat-conducting heating element 42 to the panel 80.

The distance between the panel 80 and the magnetic heat generating member 42 is D4, D4 may be approximately 0.5mm to 2mm, for example, D4 may be approximately 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, or any value between the two adjacent values. Thus, the distance between the panel 80 and the magnetic conduction heating element 42 is reasonable, which is beneficial to the compact structure of the panel 80 and the magnetic conduction heating element 42 and reduces the thermal influence of the panel 80 on the magnetic conduction heating element 42.

The panel 80 may abut against the solenoid coil panel 41, which may help to make the arrangement of the panel 80 and the solenoid coil panel 41 more compact, which may help to reduce the overall height of the air fryer 100.

The panel 80 may be a microcrystalline panel, so that the panel 80 has higher strength, better insulating properties, stable dielectric constant, and better thermal stability.

The thickness of the face plate 80 is D5, and D5 may be approximately 4mm to 6mm. For example, D5 may be approximately 4mm, 4.2mm, 4.4mm, 4.6mm, 4.8mm, 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, 6mm, or any value between any two of the foregoing.

Thus, the thickness of the panel 80 is not too thin, which increases the difficulty of manufacturing the panel 80, thereby contributing to reducing the manufacturing cost of the panel 80. The thickness of the panel 80 is not too thick, which causes the distance between the electromagnetic coil panel 41 and the magnetic conductive heating element 42 to be too large, thereby helping to ensure the heating efficiency of the magnetic conductive heating element 42. By reasonably designing the thickness of the panel 80 to be about 4mm to 6mm, the panel 80 is facilitated to simplify the manufacturing difficulty and ensure that the magnetic conduction heating element 42 has good heating efficiency.

In some embodiments, in the case that the air fryer 100 includes the panel 80, the portion of the heating fan 43 engaged with the driving shaft 31 may be a fan mounting portion, the fan mounting portion may be protruded at a side of the magnetic heat generating member 42 facing the electromagnetic coil panel 41, and the fan mounting portion may be penetrated through the panel 80. In this way, the driving shaft 31 can be connected to the fan mounting portion without protruding too much from the panel 80, so that when the heating fan 43 is detached from the driving shaft 31, the driving shaft 31 protrudes from the panel 80 to a lower height or does not protrude from the panel 80, thereby facilitating the iron pan to be smoothly placed on the panel 80.

In addition, because the fan mounting portion is disposed through the panel 80, the fan mounting portion and the panel 80 are more compactly arranged, which helps to reduce the overall height of the air fryer 100.

In the air fryer 100 that this application embodiment provided, casing 10 is equipped with heat dissipation space 11 and air outlet 12 that are linked together, wind wheel 20 rotationally is located casing 10, the air-out side 23 of wind wheel 20 is towards heat dissipation space 11, actuating mechanism 30 is connected with wind wheel 20 and is used for driving wind wheel 20 to rotate, because actuating mechanism 30 is located the first air inlet side 21 of wind wheel 20, then wind wheel 20 rotates the in-process and can inhale and carry the heat that actuating mechanism 30 produced to heat dissipation space 11 along with the air, so that the heat is discharged outside casing 10 from air outlet 12.
