When the door hook 32 is switched from the closed state to the open state, the door hook 32 drives the seat portion 3433 to move relative to the housing 31 through the transmission member 344, the seat portion 3433 drives the friction portion 3431 to move in the friction channel 3493 through the connecting plate portion 3432 in the moving process, and the extending direction of the connecting plate portion 3432 is intersected with the moving direction of the seat portion 3433, so that the friction portion 3431 tilts in the friction channel 3493 in the moving process of the connecting plate portion 3432, friction force is generated between the tilted friction portion 3431 and the friction channel 3493, the generated friction force is utilized to prevent the opening operation of the door hook 32, and meanwhile, the elastic force of the elastic member 347 also prevents the opening operation of the door hook 32, so that the hovering operation of the door body 10 is realized through the combined action of the friction force and the elastic force.

It should be noted that, as shown in fig. 6 to 10, a mounting hole 3431a is formed in the friction portion 3431, a first connection hole 3433b and a second connection hole 3433c are formed in the seat body 3433, the elastic assembly 34 includes a first connection shaft 341, a second connection shaft 342 and a third connection shaft 348, wherein the hinge between the friction portion 3431 and the link plate portion 3432 is achieved by the cooperation of the first connection shaft 341 and the mounting hole 3431a and the first connection hole 3433b, the hinge between the transmission member 344 and the seat body 3433 is achieved by the cooperation of the second connection shaft 342 and the second connection hole 3433c and the transmission member 344, and the second connection seat 3443 of the transmission member 344 is hinged with the door hook 32 by the third connection shaft 348.

When the door body 10 is opened, the housing 31 and the elastic component 34 rotate with the door body 10 relative to the machine body 20, at this time, the door hook 32 rotates relative to the housing 31, and the elastic member 347 is further stretched by the process of rotating the door hook 32, so that the resilience force of the elastic member 347 is further increased, and when the door body 10 is opened to a desired position, the resilience force of the elastic component 34 of the hinge 30, the gravity component force of the door body 10 in the vertical direction, and the friction force between the adjusting member 346 and the housing 31 are balanced, so that hovering of the door body 10 is realized.

Specifically, when the hinge 30 is in the closed state, the door 10 is in the closed state with respect to the body 20, and when the hinge 30 is in the open state, the door 10 is in the open state with respect to the body 20. When the door body 10 is in the opened state, the door body 10 has a vertically downward component force F1 in the vertical direction, and at this time, the elastic member 347 has a vertically upward component force F2, and a friction force F3 is provided between the friction portion 3431 and the friction passage 3493, wherein F2 is positively correlated with F1, and when the regulating member 346 rotates relative to the fixing base 345, the initial deformation amount of F2 is regulated to be increased, that is, the initial value of F2 is regulated, F2 is reduced when the regulating member 346 moves toward the side close to the door hook 32, and F2 is increased when the regulating member 346 moves toward the side far from the door hook 32.

When the opening angle of the door body 10 is smaller (the angle is larger than 0 degrees and smaller than or equal to 10 degrees), f2 > f1+f3, at this time, the door body 10 can be automatically closed under the action of the elastic piece 347, and when the opening angle of the door body 10 is larger (the angle is larger than 10 degrees), f2+f3≡f1, at this time, the hovering of the door body 10 can be realized.

In the embodiment of the present utility model, the resilience force of the elastic component 34 is set to drive the door hook 32 to have a tendency to switch from the open state to the closed state, when the user performs the door closing operation on the door body 10, the external force during the door closing operation can be reduced, the convenience during the door closing operation is improved, and the use experience of the user is improved.

In addition, when the hinge 30 is switched (the closed state is switched to the open state, and the open state is switched to the closed state), the movable seat 343 moves relative to the housing 31, and the adjusting member 346 applies force to the elastic member 347, so that the compression amount of the elastic member 347 is adjusted, and thus the installation requirements of door bodies 10 (door bodies 10 with different door weights) with different specifications can be satisfied.

Further, as shown in fig. 3 and 7, the friction channel 3493 is disposed along the moving direction of the movable seat 343 and includes a first movable section 3493a and a second movable section 3493b, wherein the second movable section 3493b is disposed near one side of the door hook 32, when the movable seat 343 moves in the area of the first movable section 3493a, the movable seat 343 is in clearance fit with the first movable section 3493a, there is no corresponding friction therebetween, and when the movable seat 343 moves in the area of the second movable section 3493b, there is friction therebetween.

When the hinge 30 is used for the cooking appliance 100, the elastic member 347 keeps the door hook 32 in a closed state, the door body 10 is in a closed state, and when the door body 10 is opened and is at a small angle, the movable seat 343 moves in the direction of the door hook 32 and moves in the area of the first movable section 3493a, and the elastic force generated by the elastic member 347 drives the door body 10 to be automatically closed through the adjusting member 346, the movable seat 343, the transmission member 344 and the door hook 32; when the door body 10 is opened and is at a large angle, the movable seat 343 moves in the direction of the door hook 32 and moves in the area of the second movable section 3493b, at this time, the door body 10 generates downward gravity of the door body 10 in the vertical direction, and the resilience force generated by the elastic member 347 and the friction force generated by the movable seat 343 and the friction member 349 balance with the gravity of the door body 10, so that hovering of the door body 10 can be realized, thereby meeting the use requirement of a user.

It should be understood that, by providing the first movable section 3493a, the door body 10 can be automatically closed, so that the situation that the door body 10 is not closed in place and the cooking is affected can be prevented.

It should be noted that in the embodiment of the present utility model, the opening angle of the door body 10 is referred to as a small angle (greater than 0 °) when it is less than or equal to 10 ° and the opening angle of the door body 1010 is referred to as a large angle when it is greater than 10 °.

Further, as shown in fig. 3 and 7, the second movable section 3493b is narrowed along the moving direction of the movable base 343 toward the door hook 32. Specifically, as the movable base 343 moves in the region of the second movable section 3493b, the friction between the second movable section 3493b and the movable base 343 in the narrowed structure gradually increases 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 achieves hovering.

When the second movable section 3493b is arranged in a narrowed manner, the friction force can be adapted to different weight specifications of the door body 10, and the universality of the hinge 30 is further improved.
