Description

Technical Field

[0001] The utility model relates to an air fryer. Background Art

[0002] An air fryer is a kitchen appliance that uses high-temperature air to heat and cook food. Food cooked in an air fryer has the effect of frying but contains less fat, making it delicious and healthy. As a result, air fryers are becoming more and more popular among people.

[0003] For example, in an air fryer disclosed in CN217429814U, the side walls of the air hood (i.e., the heat insulation hood) are all inclined side walls, which causes the hot air at the edge to blow toward the side walls of the inner pot, and then bounce back to the food through the side walls of the inner pot, resulting in heat loss. The food is not immediately heated, resulting in slow cooking efficiency and unsatisfactory cooking results. Utility Model Content

[0023] To further illustrate the various embodiments, the present invention provides drawings. These drawings are part of the disclosure of the present invention, which are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, a person of ordinary skill in the art should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0024] In the description of the present invention, terms such as "up", "down", "left", "right", "front", "back", etc., and the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention.

[0025] The utility model is now further described in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figures 1 to 6 As shown, the present embodiment provides an air fryer, comprising a pot body 1 and an inner pot 2, wherein the pot body 1 has an insertion cavity 3, the inner pot 2 is a pot for holding food, and the inner pot 2 can be selectively placed in the insertion cavity 3 of the pot body 1 or outside the insertion cavity 3 of the pot body 1; after the inner pot 2 holds food, it is placed in the insertion cavity 3 of the pot body 1 for cooking, and the inner pot 2 is taken out after cooking is completed.

[0027] The pot body 1 has a heat insulation cover 10 located above the insertion cavity 3 . When the inner pot 2 is placed in the insertion cavity 3 of the pot body 1 , the heat insulation cover 10 is also located above the inner pot 2 .

[0028] The heat shield 10 has a first accommodating chamber 11, a second accommodating chamber 12 and a bottom opening 13 which are arranged in sequence from top to bottom and are connected. The caliber of the second accommodating chamber 12 is larger than the caliber L1 of the first accommodating chamber 11. The first accommodating chamber 11 is equipped with the blades 22 of the fan 21. Specifically, a clearance hole 14 is opened at the top of the heat shield 10. The fan 21 is arranged at the top of the heat shield 10. The rotating shaft of the fan 21 extends into the first accommodating chamber 11 through the clearance hole 14 of the heat shield 10 and is connected to the blades 22. The second accommodating chamber 12 is equipped with a heating element 30. The side wall 121 of the second accommodating chamber 12 is a vertical side wall; that is, the side wall 121 of the second accommodating chamber 12 is arranged vertically downward.

[0029] When cooking, the fan blades 22 rotate under the drive of the fan 21 to form an air flow, and the air flow flows from the first accommodating chamber 11 to the second accommodating chamber 12, and is heated by the heating element 30 to form hot air. The hot air passes through the second accommodating chamber 12 and blows downward through the bottom opening 13 to the food in the inner pot 2. During the process, the side wall 121 of the second accommodating chamber 12 is a vertical side wall, which guides the hot air vertically downward, so that the hot air blows directly to the food. The food is conditioned by heat in the first place, reducing heat loss, effectively improving cooking efficiency, and achieving better conditioning effects.

[0030] Preferably, the diameter L2 of the heating element 30 is larger than the diameter of the fan blades 22, so as to completely cover the fan blades 22 in the vertical direction. In this way, the wind flow blown downward directly by the fan blades 22 can enter the heating element 30 to be heated into hot air. Furthermore, the diameter L2 of the heating element 30 is also larger than the caliber L1 of the first accommodating cavity 11, so as to cover the first accommodating cavity 11 in the vertical direction; in this way, whether it is the wind flow blown downward directly by the fan blades 22 or the wind flow blown downward guided by the side wall 111 of the first accommodating cavity 11, it can enter the heating element 30 to be heated into hot air, and the heating effect is better.

[0031] The side wall 111 of the first accommodating cavity 11 is an inclined side wall that is inclined outward from top to bottom. With this configuration, the inclined side wall can better guide the wind flow downward to the second accommodating cavity 12. Of course, in other embodiments, the side wall 111 of the first accommodating cavity 11 can also be a vertical side wall.

[0032] The distance L3 between the outermost layer of the heating element 30 and the vertical side wall (i.e., the side wall 121) of the second accommodating cavity 12 is between 5-10 mm, which can not only well cover the second accommodating cavity 12, but also prevent the heating element 30 from being too close to the heat insulation cover 10 so that the heat generated by the heating element 30 is excessively transferred to the heat insulation cover 10, thereby protecting other components.

[0033] The vertical depth dimension H2 of the second accommodating cavity 12 is greater than the vertical depth dimension H1 of the first accommodating cavity 11 . With this arrangement, it is easier to concentrate the wind flow in the second accommodating cavity 12 to blow downward.

[0034] Specifically, in the present embodiment, the heating element 30 is a flat heating tube obtained by spirally bending a heating tube on a horizontal plane. The thickness H3 of the heating element 30 is the diameter of the heating tube. The vertical side wall 121 of the second accommodating cavity 12 and the bottom opening 13 are transitioned through the first chamfer 15, and the distance H4 between the bottom of the heating element 30 and the bottom opening 13 is twice the vertical distance of the first chamfer 15; and the distance H4 between the bottom of the heating element 30 and the bottom opening 13 is greater than the thickness dimension H3 of the heating element 30 (i.e., the diameter of the heating tube); such a setting can make the hot air enter the inner pot 2 more effectively, reduce heat loss, and also make the heating temperature of the food close to the temperature control temperature of the heating element 30, so as to achieve a better conditioning effect.

[0035] This implementation scheme specifically demonstrates and introduces the utility model, but technicians in the relevant field should understand that various changes can be made to the utility model in form and detail without departing from the spirit and scope of the utility model defined by the attached claims, all of which are within the scope of protection of the utility model.
