Referring to fig. 1-8, the present application provides an air fryer 10. The air fryer 10 is a cooking appliance that uses high-speed hot air instead of oil to fry food. The high velocity hot air is formed by a fan-driven air flow that carries away heat generated by the heating elements. The high-speed hot air is blown to the outer surface of the food material to quickly take away the moisture, so that the outer surface of the food material is golden and crisp, and the frying effect is achieved. When the air fryer is used for a long time, the cover body is always polluted, and the air fryer needs to be cleaned regularly to prolong the service life of the air fryer. The present application provides an air fryer 10 that is an air-fry cooking appliance that facilitates cleaning of the lid.

Referring to fig. 1-3, in one embodiment of the present disclosure, an air fryer 10 is provided, wherein the air fryer 10 may include, but is not limited to, a cavity 110 and a cover assembly 200 covering the cavity 110. Cover assembly 200 includes, but is not limited to, a magnetic conductor 211, a first coil 212, an airflow driving assembly 220, and a shield 230. The first coil 212 is used for generating a first alternating electromagnetic field, and the first alternating electromagnetic field acts on the magnetic conductive member 211 to generate heat. The airflow driving assembly 220 includes, but is not limited to, a fan 222, the fan 222 is spaced apart from the magnetic conductive member 211, and is used for driving the airflow to transport the heat generated by the magnetic conductive member 211 to the inner cavity of the chamber 110. Shield 230 is positioned between first coil 212 and the interior cavity of chamber 110.

It will be appreciated that the shield 230 is used to cover the first coil 212. Specifically, the shield 230 can shield sputtering from the inner cavity of the chamber 110, and maintain the cleanliness of the first coil 212 to avoid frequent cleaning. Meanwhile, because the structure of electromagnetic heating is different from the structure of heating by an electric heating wire, the magnetic conduction member and the first coil in the air fryer 10 provided by the embodiment do not need to be connected with each other, and the magnetic conduction member is convenient to detach for cleaning.

The cover assembly 200 further includes an upper cover 240. The cover 240 is spaced apart from the shield 230 to define a receptacle. Within this cavity is a first coil 212. Thus, the first coil 212 located in the cavity is wrapped to prevent contamination of the sputtering material from the inner cavity of the chamber 110.

The air fryer 10 also includes a stationary member 310 and a carrier member 320. The fixing member 310 is a ring-shaped member. The fixing member 310 includes, but is not limited to, an inner side portion 311, an outer side portion 312, and a connecting portion 313 connecting the inner side portion 311 and the outer side portion 312, which are coaxially disposed. The inner portion 311 and the outer portion 312 are axially offset such that the inner portion 311, the connecting portion 313, and the outer portion 312 form a stepped ring. The outer part 312 is fixed to the upper cover 240. The inner portion 311 is further from the upper cover 240 relative to the outer portion 312 and the shutter 230. The inner portion 311 carries the shield 230 on a peripheral side, and in other embodiments, the inner portion 311 may not carry the shield 230 on a peripheral side. The carrier 320 is connected to the inner side 311. The carrier 320 is further away from the upper cover 240 relative to the shielding member 230 for holding the magnetic conductive member 211.

Optionally, the material of the fixing member 310 and the supporting member 320 is a plastic material that is heat-resistant, non-toxic, and flexible, and may be specifically silicone. The fixing member 310 and the supporting member 320 can be connected by a snap-fit connection, which is convenient to mount and dismount and can be mounted and dismounted without tools.

It can be understood that, since the magnetic conductive member 211 is supported by the supporting member 320, the magnetic conductive member 211 can be removed alone or together with the supporting member 320 from the fixing member 310 for effective and thorough cleaning during regular maintenance after being contaminated, so as to prolong the service life of the air-fryer 10.

Optionally, the magnetic conductive member 211 is made of magnetic material such as ferrite, and the magnetic conductive member 211 may be composed of a series of concentric magnetic conductors.

The carrier 320 has a plurality of second through holes 321. The second conduction hole 321 is used for circulating the airflow with the heat emitted by the magnetic conductive member 211. The heated air flow reaches the inner cavity of the cavity 110 to fry and cook the food in the inner cavity.

The shield 230 has a mounting hole 231. The airflow drive assembly 220 also includes a motor 221. The motor 221 is fixed in the cavity. The output shaft of the motor 221 passes through the mounting hole 231. The fan blades 222 are mounted on an output shaft of the motor 221. The fan blades 222 are located between the magnetic conductor 211 and the shielding member 230. Therefore, the magnetic conductive member 211 in this embodiment serves as a "shield" for the fan blade 222, and shields the sputtering material from the inner cavity of the cavity 110, thereby reducing the possibility of contamination of the fan blade 222.

It can be understood that the supporting member 320 in this embodiment can also play a role of protection in addition to supporting the magnetic conductive member 211, so as to prevent the magnetic conductive member 211 and the fan blades 222 from being greatly contaminated during the cooking process.

Alternatively, the airflow driving assembly 220 may also be a turbofan.

The air fryer 10 also includes a second coil 121. The second coil 121 is located outside the cavity 110. Since at least a portion of the chamber 110 is a magnetic conductor. Therefore, when the second alternating electromagnetic field generated by the second coil 121 is applied to the magnetizer to generate heat, the cavity 110 is heated. Thus, two heating sources are arranged in the air fryer 10 during operation, so that food materials can be fried more fully and comprehensively, and the cooking time is greatly reduced.

In practical applications, the food material to be fried is first placed into a fry basket. The frying basket is a vessel specially designed for being matched with an air frying pan for air-frying cooking. The bottom of the frying basket is carved with air guide grains, and the peripheral side is provided with air vents. The fry basket with food material is located in the inner cavity of the cavity 110, and the cover assembly 200 covers the cavity 110, so that air frying cooking can be performed.

Specifically, alternating current is applied to the first coil 212 to generate a first alternating electromagnetic field, and the first alternating electromagnetic field acts on the magnetic conductive member 211, so that the magnetic conductive member 211 generates heat. Meanwhile, the airflow driving assembly 220 is started, so that the airflow passes through the magnetic conduction member 211 and takes away the heat dissipated by the magnetic conduction member to the inner cavity of the cavity 110, and the frying and cooking of the food in the inner cavity are realized. The high-temperature airflow contacts the surface of the food material, so that the food material is quickly dehydrated to become golden and crisp, and the frying effect is achieved.

During cooking, the magnetic conductive member 211 may be contaminated. When the magnetic conductive member 211 is contaminated to a certain extent, the magnetic conductive member 211 needs to be cleaned. Since the magnetic conducting member 211 is supported by the supporting member 320, and the supporting member 320 is connected to the fixing member 310 by a snap fit, the cover assembly 200 can be opened to buckle the supporting member 320 by hand, and then the magnetic conducting member 211 can be cleaned or the magnetic conducting member 211 can be detached from the supporting member 320 and then cleaned. And after the magnetic conduction member 211 is cleaned, the magnetic conduction member is installed back in the reverse process.

Referring to fig. 4, a second embodiment of the present application provides an air fryer 10. The air fryer 10 includes, but is not limited to, a fixture 310. The fixing member 310 is a ring-shaped member. The fixing member 310 includes, but is not limited to, an inner side portion 311, an outer side portion 312, and a connecting portion 313 connecting the inner side portion 311 and the outer side portion 312, which are coaxially disposed. The inner portion 311 and the outer portion 312 are axially offset such that the inner portion 311, the connection portion 313, and the outer portion 312 form a stepped ring. The outer part 312 is fixed to the upper cover 240. The inner portion 311 is further from the upper cover 240 relative to the outer portion 312 and the shutter 230. The inner portion 311 carries the circumferential side of the mask 230, in other embodiments, the inner portion 311 may not carry the circumferential side of the mask 230. The magnetic conduction member 211 is connected to the inner portion 311.

The shield 230 has a mounting hole 231. The airflow driving assembly 220 includes, but is not limited to, a motor 221 and a fan 222. The motor 221 is fixed in the cavity. The output shaft of the motor 221 passes through the mounting hole 231. The fan blades 222 are mounted on an output shaft of the motor 221. The fan blades 222 are located between the magnetic conductor 211 and the shielding member 230. Therefore, the magnetic conductive member 211 in this embodiment serves as a "shield" for the fan blades 222, and shields the sputtering material from the inner cavity of the cavity 110, thereby reducing the possibility of contamination of the fan blades 222.

The magnetic conductive member 211 has a plurality of first via holes 2111. The first conduction hole 2111 is used for circulating the air flow with the heat emitted from the magnetic conductive member 211. The heated air flow reaches the inner cavity of the cavity 110 to fry and cook the food material in the inner cavity.

The present embodiment provides an air fryer 10, which is different from the air fryer 10 provided in the first embodiment in that: the magnetic conductive member 211 replaces the carrier 320, and no additional carrier 320 is needed, and the first through hole 2111 may also be the second through hole 321.

When the magnetic conduction member 211 is polluted, the magnetic conduction member can be quickly detached for effective and thorough cleaning.

Compared with the air fryer 10 of the first embodiment, the structure of the air fryer 10 of the present embodiment is simpler, and the degree of contamination of the magnetic conductive member 211 is easier to observe.

Referring to fig. 5 and 6, a third embodiment of the present application provides an air fryer 10. The difference between the air fryer 10 of the present embodiment and the air fryer 10 of the second embodiment is that: the magnetic conductive member 211 has an escape hole 2112. The magnetic conductor 211 is located between the fan blade 222 and the shielding member 230. The output shaft of the motor 221 passes through the escape hole 2112.

Referring to fig. 7, a fourth embodiment of the present application provides an air fryer 10. The air fryer 10 of the present embodiment is different from the air fryer 10 of the second embodiment in that: the air fryer 10 also includes a heat generating assembly 400.
