In addition, the friction member 341 is provided with a first limit structure 3411, and the housing 31 is provided with a second limit structure 311, so that when the friction member 341 is mounted on and fixed to the housing 31 (screw connection, adhesion, welding, or the like is possible), the position accuracy of the friction member 341 is ensured by the cooperation of the first limit structure 3411 and the second limit structure 311 (for example, the first limit structure 3411 is a protruding structure, and the second limit structure 311 is a clamping groove structure, or the like).

In addition, the friction member 341 is provided with a first guiding structure 3413, the movable seat 342 is provided with a second guiding structure 3423, the adjusting member 343 is provided with a third guiding structure 3432c, when the movable seat 342 is mounted in place in the friction channel 3412, the first guiding structure 3413 is matched with the second guiding structure 3423, the third guiding structure 3432c is also matched with the first guiding structure 3413, and the first guiding structure 3413 is respectively matched with the second guiding structure 3423 and the third guiding structure 3432c (for example, the first guiding structure 3413 is a guiding protrusion, the second guiding structure 3423 is a first guiding groove, the third guiding structure 3432c is a second guiding groove, etc.), thereby ensuring the moving direction of the movable seat 342.

Further, as shown in fig. 6 and 9, the second movable section 3412b is narrowed along the moving direction of the movable base 342 toward the door hook 32. Specifically, as the movable base 342 moves in the region of the second movable segment 3412b, the friction between the second movable segment 3412b and the movable base 342 in the narrowed structure gradually increases as the movable base 342 moves toward one side of the door hook 32, and when the friction and the resilience of the elastic member 344 are equal to the gravitational separation of the door body 10, the door body 10 hovers.

By providing the second movable segment 3412b in a narrowed configuration, the friction force can be adapted to different door body 10 weight specifications, further improving the versatility of the hinge 30.

As shown in fig. 1 to 12, the present utility model also proposes a cooking appliance 100, the cooking appliance 100 comprising a first structural member, a body 20 and a hinge 30 according to the above, the first structural member is a door body 10, a cooking cavity and a second structural member are provided on the body 20, the second structural member is a front plate 21, the front plate 21 is annularly provided outside an opening of the cooking cavity, the hinge 30 is provided below the door body 10, and a housing 31 of the hinge 30 is connected with the door body 10, and a door hook 32 of the hinge 30 is connected with the front plate 21.

Specifically, when the hinge 30 is specifically applied to the cooking apparatus 100, the hinge 30 is installed between the door body 10 and the body 20 of the cooking apparatus 100, the first structural member is the door body 10, the second structural member is the front plate 21 of the body 20, and the door body 10 is in a flip-down structure, wherein the housing 31 of the hinge 30 is fixed to the door body 10, the door hook 32 of the hinge 30 is connected to the front plate 21, and the component force of the door body 10 in the vertical direction is overcome by using the resilience force of the resilient member 344, so that the door body 10 is closed or hovered. When the specification of the door body 10 changes, the compression amount of the elastic member 344 is changed by adjusting the adjusting member 343, so as to adjust the resilience force of the elastic member 344, thereby meeting the installation requirements of the door body 10 with different specifications, and improving the universality of the hinge 30.

In the present utility model, the cooking appliance is a large oven or a whole oven, and the structure of other parts of the cooking appliance is referred to the prior art, and the disclosure is not repeated here.

The present utility model is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present utility model are intended to be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
