Description

Technical Field

[0001] This utility model relates to an air fryer. Background Technology

[0002] Chinese Patent Publication No. CN223111542 U, published on July 18, 2025, discloses a shell and an air fryer. The shell includes an upper shell and a second side plate. The upper shell is integrally formed and includes a top plate and two first side plates. The upper ends of the two first side plates are respectively connected to the two opposite ends of the top plate along a first direction. There are two second side plates, which are arranged at intervals along the first direction. The second side plates correspond one-to-one with the first side plates, and the upper end of the second side plate is detachably connected to the lower end of the corresponding first side plate. In this structure, the side plates are detachably connected by two upper and lower first and second side plates. Since the shell has a certain height, and the connection point of the first and second side plates is approximately located at the middle height of the shell and on the inner side of the side plate, a connector (screw) is required to connect the shell before it is installed outside the air fryer inner liner. The internal space of the shell is limited, making it inconvenient for pneumatic or electric tools to reach into the shell to tighten the screws.

[0003] In addition, the gap formed by the splicing of the first and second side panels in the middle of the outer shell side wall easily accumulates dirt, affecting the product's appearance.

[0004] Furthermore, the lower end of the second side panel extends out to form a foot pad. The material of the second side panel is generally the same as that of the first side panel, and its main function is decorative. The main function of the foot pad is to support and bear weight. The fact that the foot pad is integrated with the side panel inevitably limits the function of the foot pad. Utility Model Content
