Specifically, the length of the second arm 132 is smaller than that of the first arm 130, which is beneficial to effectively connecting the driving member 120 with the door hook when the door body 310 is closed, and beneficial to effectively separating the driving member 120 from the door hook after the door body 310 is opened.

The interlock structure 100 further includes a trigger structure 170, and the user can drive the driving member 120 to rotate in the second direction through the trigger structure 170.

The button 172 is used to drive the rotation member 174 to move, so that the rotation member 174 drives the driving member 120 to rotate in the second direction.

Specifically, the key 172 and the rotating member 174 are two relatively independent devices, and pressing the key 172 can bring the key 172 into contact with the rotating member 174, and as the pressing force increases, the key 172 can drive the rotating member 174 to rotate.

The key 172 is disposed corresponding to the first rotation section 176.

Example 15:

the interlock structure 100 can ensure that the door 310 can be automatically closed by the driving member 120 as long as the door hook touches the driving member 120. Meanwhile, the damper can play a role in reducing the speed and buffering the door closing, so that the noise of the door closing can be reduced. When the door is opened, the rotating piece 174 is triggered by the button 172, and the rotating piece 174 pushes the driving piece 120 to push out the door hook, so that the door body 310 is opened.

The interlocking system has the functions of buffering door closing and noise reduction and also has the function of opening the door in one step through the key 172.

The door closing process: after the door hook touches the driving member 120, the driving member 120 rapidly goes beyond the equilibrium position, and the rotating direction is changed from the clockwise rotating trend to the counterclockwise rotating trend. The door hook moves rapidly under the action of the first elastic member 152 and the second elastic member 154, and then the damper acts, so that the door body 310 decelerates, and the damper is started when the door is closed, thereby having a buffering and noise-reducing effect.

And (3) door opening process: pressing the button 172 turns the rotor 174, and the rotor 174 drives the driving member 120 clockwise until the door is opened.

Forced closing the door: when the actuator 120 is triggered by accident or for unknown reasons, but the door is not closed, the actuator 120 will rotate to the closed door position. At this time, the door cannot be normally closed. When a large force is used to close the door, the front end of the door hook pushes the first escape vacancy 136 of the driving member 120 and slides away, so that the door hook transitions to the normal door closing position. At this time, the door can be normally opened and closed.

The horizontally moving push rod 200 activates two second switches 210.

The linkage protrusion 204 of the push rod 200 is located behind the second arm 132 of the driving member 120 and is blocked by the second arm 132, so that it can prevent a foreign object with a thickness of 3mm or more from extending into and pushing the push rod 200.

The bracket 110 of the interlocking structure 100 is connected to the box structure. The door 310 is connected with the box structure in an openable and closable manner.

When the door 310 is opened, the driving member 120 is located in the second area. Close the in-process of a body 310, the door hook removes towards driving piece 120, after door hook touching driving piece 120, driving piece 120 rotates for support 110 under the exogenic action, when driving piece 120 rotates to first region, driving piece 120 rotates along the first direction under the effect of elastic component, driving piece 120 rotates and to drive the door hook that is connected with it cooperation and move inwards, until closing a body 310, the self-closing operation of a body 310 has been realized, user's both hands have been liberated, it closes the door to have accomplished the intellectuality, the degree of automation of product has been promoted. Meanwhile, the arrangement can prevent a user from taking out food and turning to close the door body 310, simplify the operation steps of the cooking appliance 300, prevent oil stain on the hands of the user from being stained on the door body 310, and reduce the frequency of cleaning the cooking appliance 300. And because can realize closing the door automatically, so can avoid hanging the collision door body 310 because of forgetting to close door body 310, and then the condition that leads to cooking utensil 300 to fall takes place, is favorable to promoting security and the reliability that the product used.

Specifically, the cooking appliance includes a microwave oven, an oven, a steam box or a steaming and baking all-in-one machine, etc., which are not listed here.
