Specifically, as the movable base 343 moves in the region of the second movable section 3413b, the friction between the second movable section 3413b in the narrowed structure and the movable base 343 increases gradually as the movable base 343 moves toward one side of the door hook 32, and when the friction and the resilience of the resilient member 347 are equal to the gravitational separation of the door body 10, the door body 10 hovers.

By providing the second movable segment 3413b 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 9, the present utility model also proposes a cooking appliance 100, the cooking appliance 100 comprising a first structural member, a body 10 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 on 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 347, 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 347 is changed by adjusting the adjusting member 342, so that the resilience force of the elastic member 347 is adjusted, the installation requirements of the door bodies 10 with different specifications are met, and the universality of the hinge 30 is improved.

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 description thereof is omitted herein.

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.
