As shown in fig. 1 to 12, according to an embodiment of the present utility model, a hinge 30 for a cooking appliance 100 is provided, wherein the hinge 30 includes a housing 31, a door hook 32, a link assembly 34, and an elastic assembly 35.

Specifically, the elastic member 35 and the door hook 32 are respectively provided on the housing 31, the door hook 32 is rotatable with respect to the housing 31, the door hook 32 has two states, i.e., an open state and a closed state, the housing 31 is connected to one end of the elastic member 353 of the elastic member 35, the door hook 32 is connected to the other end of the elastic member 353 through the link member 34, the elastic member 353 has a resilient force acting on the door hook 32 through the link member 34, so that the door hook 32 has a tendency to switch to the closed state. Wherein, in the open state of the door hook 32, the link assembly 34 has two action sections, namely a hover action section for closing the door body 10 and a door closing action section for hovering of the door body 10.

When the hinge 30 is specifically applied to the cooking appliance 100, the door body 10 of the cooking appliance 100 is of a flip-down structure in which one of the door body 10 and the front plate 21 of the body 20 is fixedly coupled to the housing 31 of the hinge 30, the other of the door body 10 and the front plate 21 is fixedly coupled to the door hook 32, the elastic member 353 has a resilient force and applies a force to the door hook 32 through the link assembly 34, the resilient force of the elastic member 353 performs a door closing operation on the door body 10 when the link assembly 34 is in a door closing section, and the resilient force of the elastic member 353 performs a hover operation on the door body 10 when the link assembly 34 is in a hover section.

The present utility model reduces the number of the elastic members 353 compared to the prior art, so that the structure of the hinge 30 can be simplified, and the manufacturing cost of the hinge 30 can be reduced.

It should be understood that in the embodiment of the present utility model, after the elastic member 353 is mounted, the elastic member 353 is in a stretched state, thereby having a resilient force. The elastic force has a vertical component force for canceling the gravity of the door body 10, and when the vertical component force is greater than the gravity of the door body 10, the door body 10 performs a door closing action, and when the vertical component force is equal to the gravity of the door body 10, the door body 10 is in a hovering state.

When the door body 10 is opened, the housing 31 and the elastic member 35 are rotated with the door body 10 relative to the body 20, and at this time, the door hook 32 is rotated relative to the housing 31, and the elastic member 353 is further stretched by the rotation of the door hook 32, so that the resilience of the elastic member 353 is further increased. When the door body 10 is opened at a smaller angle (the opening angle is larger than 0 degrees and smaller than or equal to 10 degrees), the connecting rod assembly 34 is in the door closing action area, the vertical component force of the resilience force is larger than the gravity of the door body 10, and the resilience force can perform automatic door closing action on the door body 10, so that a user does not need to perform door closing action on the door body 10, convenience in the use process of the user is improved, and the use experience of the user is further improved. When the angle of opening the door body 10 is larger (the angle of opening is larger than 10 °), the connecting rod assembly 34 is in the door closing action area, the vertical component of the resilience force is equal to the gravity of the door body 10, and the resilience force is offset with the gravity of the door body 10, so that the door body 10 can hover at the opening angle, further the requirement of a user on the opening angle of the door body 10 is met, and the use experience of the user is further improved.

It should be noted that, the housing 31 is provided with a connection structure, such as a mounting hole, through which a fastener, such as a screw, is passed when the hinge 30 is used for the cooking appliance 100, to connect and fix the housing 31 of the hinge 30 to the door body 10, and the door hook 32 is passed through the front plate 21 of the body 20 and is engaged with the front plate 21.

The hook portion 321 of the door hook 32 is disposed opposite to the obtuse opening when the door hook 32 is in the closed state.

Specifically, by providing the first sliding hole 3451 as two sliding sections and setting the manner of the two sliding sections, the link assembly 34 is enabled to have a door closing action section and a hover action section, thereby satisfying different opening and closing demands of the user on the door 10 when the hinge 30 is used for the cooking appliance 100.

It should be noted that, in the embodiment of the present utility model, the first sliding section 3451a and the second sliding section 3451b adopt an arc transition, so that the jamming condition of the first connecting shaft 343 at the transition position of the first sliding section 3451a and the second sliding section 3451b is reduced, and the effective implementation of the function of the hinge 30 is ensured.
