In order that the above-recited objects, features and advantages of the present application will be more clearly understood, a more particular description of the application will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, without conflict, the embodiments of the present application and features in the embodiments may be combined with each other.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, however, the present application may be practiced in other ways than those described herein, and therefore the scope of the present application is not limited to the specific embodiments disclosed below.

The interlocking structure 100 and the cooking appliance 300 according to some embodiments of the present application are described below with reference to fig. 1 to 43.

Example 1:

as shown in fig. 1, 2 and 3, an embodiment of the first aspect of the present application provides an interlocking structure 100 for cooperating with a door body 310, the door body 310 including a door hook, the interlocking structure 100 including a first lock structure 110 and a second lock structure 180, and the door body 310 including the door hook.

The first lock structure 110 includes a mating member 112, and movement of the mating member 112 can either pull the door hook in a first direction to a closed door position or push the door hook in a second direction to an open door position.

The second lock structure 180 includes a locking member 182, the locking member 182 being movable between a first position and a second position.

Wherein, when the locking member 182 is in the first position, the locking member 182 restricts the movement of the mating member 112 in the second direction, and the mating member 112 restricts the movement of the door hook; when the locking member 182 is in the second position, the locking member 182 releases the engagement member 112 from movement in the second direction.

After the door 310 is locked, and the locking member 182 is in the first position, the locking member 182 limits the movement of the engaging member 112 along the second direction, that is, the engaging member 112 cannot move along the second direction, so that the engaging member 112 cannot continue to push the door hook, and the engaging member 112 can also limit the movement of the door hook. To block the door 310, the door 310 cannot be opened, and at this time, even if a child pulls the door 310, the door 310 cannot be unlocked. That is, the first lock structure 110 and the second lock structure 180 cooperate to realize the child lock function, and the door 310 cannot be opened after the door 310 is locked and the locking member 182 is in the first position.

When the locking member 182 is in the second position, the locking member 182 releases the restriction on the movement of the mating member 112 along the second direction, and the mating member 112 can move along the second direction to push the door hook to the door opening position, so as to achieve the purpose of unlocking the door body 310.

That is, when the door 310 is opened, the locking member 182 needs to be moved to the second position, and then the engaging member 112 is used to push the door hook to the door opening position along the second direction.
