Description

Technical Field

[0001] The utility model relates to a control box of an air fryer, in particular to a suspension structure of the control box of the air fryer. Background Art

[0002] An air fryer is a new type of household appliance that uses high-speed air circulation technology to fry food. Compared to traditional electric fryers, the food it cooks uses 80% less oil and fat. It is easy to clean, safe, and economical, making it highly popular. These air fryers primarily use a display or control box on the top or above the opening to control function settings. These displays or control boxes are relatively fixed in structure, making them difficult to flip for use. For example, Chinese patent publications such as CN217090399U, dated August 2, 2022, and titled "Air fryer with a flip-up display," and CN216202046U, dated April 5, 2022, and titled "Air fryer with a flip-up display," also disclose similar products. However, the flip-up displays of these products and similar products lack a fixed hinge design, making them difficult to position and limit after flipping, resulting in poor stability. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the present invention aims to provide a dual-pot air fryer with upper and lower back-blowing ventilation, addressing the technical issues of existing similar home appliances, such as the lack of a positioning and hovering hinge design for the flip display, the difficulty in positioning and limiting the display after flipping, and the poor stability after flipping. This objective is achieved through the following technical solution.

[0004] The invention relates to a control box suspension structure of an air fryer, wherein the control box of the control box suspension structure is arranged at the top front end above one side of the body opening, a PCB control component is provided in the control box, and the bottom side of the control box is hinged to the shell bracket through the control box bracket, and a suspension hinge is provided at the hinge; the key points of its structural design are that the suspension hinge includes a nut, a screw, and corresponding first anti-slip gasket A, anti-slip gasket B, anti-slip gasket C, and second anti-slip gasket A, the screws are symmetrically arranged on the lugs at both ends of the hinge of the control box bracket and the shell bracket, the screws respectively pass through the control box bracket and the shell bracket at the hinge and are connected with the nut, the outer diameter of the screw between the control box bracket and the shell bracket at one end of the connection between the control box bracket and the shell bracket is respectively provided with an anti-slip gasket C, the outer diameter of the screw between the shell bracket and the nut at the other end of the connection between the control box bracket and the shell bracket is respectively provided with a first anti-slip gasket A, anti-slip gasket B, and second anti-slip gasket A, and at least two or more anti-slip gaskets B are provided between the first anti-slip gasket A and the second anti-slip gasket A. The control box is not limited to being located at the top front end above the opening of the appliance; it can also be located elsewhere on the outer diameter of the appliance as needed. Furthermore, existing damping hinges are primarily used for vertically positioning cabinet doors to open and close them, making them difficult to use in household appliances where the control box needs to be opened from the top, primarily due to insufficient load-bearing capacity and difficulty achieving hovering stability.

[0005] The control box can be suspended arbitrarily at 0-60 degrees through the suspension hinge.

[0006] The teeth on one side of the anti-slip gasket C are evenly spaced and mesh with the protruding tooth ring ribs on the housing bracket, thereby further improving the stability and positioning effect of the hovering.

[0007] The screw is replaced with a long screw that passes through the lugs at both ends of the control box bracket and the housing bracket at the hinged joints and is connected to the nuts. The two inner ends of the long screw are clamped outwards by other nuts on both sides. The two other nuts inside the long screw can also be replaced with bushings.

[0008] The long screw rod passes through the control box bracket and the housing bracket at the hinged joints on both sides and is connected to the nut. The other two nuts on the inner side of the long screw rod are omitted. As a result, the lugs at both ends of the control box bracket and the housing bracket are replaced by the shaft edge, which improves stability and makes installation more convenient.

[0009] The shell bracket is arranged in a groove at the top front end above one side of the body opening. When the control box is closed, the top of the control box is flush with the top of the body, and a gap or side groove is left to facilitate the opening of the control box. The side groove is arranged at the edge of the control box or the edge of the groove at the top of the body.

[0010] The utility model has a simple and reasonable structural design, is easy to produce, install and use, has low production cost, good stability, long service life, and a wide range of applications, especially good positioning and hovering effect; it is suitable for use as a flip display screen of an air fryer, and is a structural improvement of similar products.
