The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment.

Examples:

this embodiment provides an air fryer, as shown in FIG. 1, comprising an outer housing 1 and a pot 2 disposed in the outer housing 1. The outer shell 1 is mainly used for supporting and protecting the whole air fryer and improving the beauty of the air fryer. The pan body 2 is mainly used for containing food materials. As shown in fig. 2, the air fryer in this embodiment further comprises an inner housing 3, the inner housing 3 being disposed between the outer housing 1 and the pot 2, primarily for providing support and positioning for the internal components of the air fryer. The top of the inner housing 3 is provided with a heating unit 4, the heating unit 4 being mainly used for providing a heat source for the air fryer. Specifically, the heating unit 4 includes an electric heating wire and a fan. The fan blows the air heated by the electric heating wire into the pan body 2, and the electric heating wire and the fan are common technical means in the field, and are not described herein.

The pot body 2 and the inner shell 3 are matched to form a containing cavity, as shown in fig. 2, and in order to make food heated uniformly, the air fryer in the embodiment is provided with a baking cage 5 in the containing cavity. As shown in fig. 3 and 4, the baking cage 5 can rotate under the drive of the driving mechanism 6 and the transmission mechanism 7 arranged on the inner shell 3, so as to realize uniform heating of food.

When the air fryer works, the electric heating wires in the heating unit 4 are electrified to heat, so that the air around the electric heating wires is heated. The fan is operated so that air flows. The air continuously flows and heats up, and hot air circulation is generated. The flowing hot air passes through the roasting cage 5, so that moisture on food materials in the roasting cage 5 is taken away, and a frying-like effect is generated. In the heating process, the baking cage 5 is driven to rotate by the transmission mechanism 7, so that food materials in the baking cage 5 are heated uniformly.

As shown in fig. 2 and 4, since the food in the roast basket 5 needs to be heated via the hot air circulation, the roast basket 5 needs to be penetrated inside and outside, and the roast basket 5 needs to have as little influence on the hot air circulation as possible. For this reason, the baking cage 5 is cylindrical, and the side wall of the baking cage 5 is made of metal mesh, and the metal mesh has meshes, and can pass through air, so that the influence on hot air circulation is small. The upper and lower bottoms of the roasting cage 5 are circular hard plates, and the upper and lower bottoms of the roasting cage 5 hardly affect the circulation of hot air, so the structure of the roasting cage is not limited in the embodiment, and the roasting cage is preferably a metal circular plate. The side wall of the baking cage 5 is provided with a driving wheel 51, the driving wheel 51 is sleeved on the side wall of the baking cage 5, and in the embodiment, the driving wheel 51 and a side bottom plate of the baking cage 5 are integrally formed. The drive wheel 51 is adapted to cooperate with the drive mechanism 7 to rotate the baking basket 5 in a manner to be described hereinafter.

The air fryer in this embodiment drives the baking basket 5 to rotate through the driving mechanism 6 and the transmission mechanism 7, specifically, as shown in fig. 4, 5 and 6, the driving mechanism 6 is disposed on the inner housing 3, and the motor support 32 for supporting and fixing the driving mechanism 6 is disposed on the inner housing 3. In the present embodiment, the driving mechanism 6 is a driving motor, and the motor support 32 is a corresponding driving motor fixing member. It will be appreciated that in other embodiments, the drive mechanism 6 may be a drive motor or other power device, and the motor support 32 may be modified accordingly.

The transmission mechanism 7 is arranged on the inner shell 3, and the transmission mechanism 7 is connected and positioned through the supporting frame 31. Specifically, the transmission mechanism 7 includes a worm 71, a worm wheel 72, and a driven wheel 73. The worm 71 is fixed to the drive mechanism 6, so that the worm 71 can move under the drive of the drive mechanism 6. The inner housing 3 is provided with a support frame 31 for supporting the worm wheel 72, and as shown in fig. 5 and 6, the support frame 31 includes a rotating wheel 311 and a support shaft 312. One end of the support shaft 312 is fixed to the rotating wheel 311, and the other end is supported on the inner housing 3 so as to be rotatable relative to the inner housing 3. The support shaft 312 is also fixedly provided with a worm wheel 72, and the worm wheel 72 is used for matching with the worm 71, so that power can be transmitted to the support shaft 312 by the driving mechanism 6. The driven wheel 73 is sleeved on the outer peripheral surface of the rotating wheel 311. In order to avoid sliding of the driven wheel 73 relative to the rotating wheel 311, specifically, in the axial direction, the driven wheel 73 is nested on the rotating wheel 311, and the rotating wheel 311 is clamped in a groove in the inner periphery of the driven wheel 73; in the circumferential direction, one, two or more grooves are further formed in the groove of the driven wheel 73, correspondingly, protrusions corresponding to the grooves are arranged on the rotating wheel 311, and the protrusions are matched with the grooves, so that the driven wheel 73 and the rotating wheel 311 cannot move relatively in the circumferential direction, and the rotating wheel 311 can drive the driven wheel 73 to rotate. It will be appreciated that the engagement of the two may also be such that the grooves on the wheel 311 fit with the protrusions on the driven wheel 73.

The driven pulley 73 is in mating contact with the driving pulley 51 and is driven by friction. The driven pulley 73 is made of a flexible material having a certain strength, such as silicone rubber, etc. The radius of the driven wheel 73 is R1, the radius of the driving wheel 51 is R2, the distance between the center of the setting position of the driven wheel 73 and the center of the setting position of the driving wheel 51 is R3, and R3 is smaller than R1+ R2, so that the driven wheel 73 and the driving wheel 51 are mutually extruded and deformed, and the driven wheel 73 is made of flexible materials and can be greatly deformed and contacted with the driving wheel 51 in a larger area, so that the friction force between the driven wheel 73 and the driving wheel 51 is larger, and the driven wheel 73 can drive the driving wheel 51 to move.

When the air fryer works, the driving mechanism 6 works to drive the worm 71 to rotate, the worm 71 drives the worm wheel 72 to rotate, the worm wheel 72 drives the supporting shaft 311 to rotate, the supporting shaft 311 drives the rotating wheel 312 to rotate, the rotating wheel 312 drives the driven wheel 73 to rotate, and the driven wheel 73 drives the baking cage 51 to rotate, so that food in the baking cage 51 is heated uniformly.

It will be appreciated that the driven wheel 73 made of soft material drives the baking cage 51 to rotate through friction, so that the driven wheel 73 is worn, and the long-term abrasion of the driven wheel 73 can loosen the matching between the driven wheel 73 and the baking cage 51, so that the baking cage 51 cannot well receive the driving of the driven wheel. The inventor verifies that under normal frequency use conditions, the time when the baking basket 51 and the driven wheel 73 are no longer normally matched meets the relevant standards.

The above is only a specific embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and it should be understood by those skilled in the art that the present utility model includes but is not limited to the accompanying drawings and the description of the above specific embodiment. Any modifications which do not depart from the functional and structural principles of the present utility model are intended to be included within the scope of the appended claims.
