That is, to operate the trigger 132 from the top of the appliance body 210, the arrangement is such that the height of the part of the trigger 132 located outside the appliance body 210 from the ground is higher, so that the child cannot easily touch the trigger 132, and therefore, the probability of the child touching the trigger 132 by mistake is further reduced.

Specifically, the cooking appliance 200 includes a microwave oven, an oven, a steam box, a steaming and baking integrated machine, and the like, which are not listed here.

Example 10:

the locking assembly includes a substrate 110, a door 120 and a lock structure 130, wherein the lock structure 130 includes a trigger 132, a limiting member 134, a resistance increasing member 138 and a seat body 136. The trigger 132: the front end of the trigger 132 is provided with a limiting member 134, and the limiting member 134 is embedded in the matching portion 122 of the door body 120 to lock the door body 120. The resistance increasing member 138: when the original state is elongation, the triggering member 132 descends due to gravity, and the resistance increasing member 138 can slow down the descending speed of the triggering member 132.

The base body 136: the base 136 and the resistance-increasing member 138 are fixed, and the base 136 is fixed to the cover 214 of the appliance body 210.

When the door 120 is in the closed state, the limiting member 134 enters the engaging portion 122 (e.g., the engaging portion 122 is a positioning groove) of the door 120, and the door 120 can be opened only when the triggering member 132 is lifted, so that the child lock function is achieved.

When the trigger 132 is lifted, the limiting member 134 is separated from the positioning groove of the door 120, and the child lock is disabled. If the door body 120 is pulled at the same time, the door body 120 is pulled open, and the unlocking action of the child lock is completed. At this time, the trigger 132 will descend due to gravity, and under the action of the resistance-increasing member 138, the trigger 132 will slowly descend until the lower plane falls on the surface of the cover 214.

When the door 120 is closed, the door 120 exerts a horizontal force on the front end of the trigger 132. Because the limiting member 134 is beveled (e.g., the limiting member 134 is provided with the first mating surface 148), the door 120 pushes the triggering member 132 to move upward. When the door 120 is completely closed, the limiting member 134 is embedded into the positioning groove of the door 120, so as to achieve the effect of automatic locking.

When the child lock breaks down and needs to be maintained, the screw on the seat body 136 can be unscrewed by the screwdriver for maintenance. This can effectively prevent the child lock from malfunctioning and making it impossible to open the door 120.

That is to say, the door 120 and the lock structure 130 cooperate to realize the function of a child lock, and the door 120 cannot be opened when the limiting member 134 is located at the first position and cooperates with the cooperating portion 122. When the limiting member 134 is located at the second position, the limiting member 134 is separated from the matching portion 122, so that the door body 120 can be opened, and at this time, the purpose of unlocking the door body 120 can be achieved by pulling the door body 120. The problem that children mistakenly touch the key or the door to unlock the door in the related technology can be effectively solved, and the safety and the reliability of the appliance including the locking assembly in use can be guaranteed. It can be understood that the limiting member 134 can move between a first position limiting the movement of the door 120 and a second position releasing the limitation of the door 120. When the limiting member 134 is at a position other than the second position, the door 120 is in a state of being limited to move. That is, when the stopper 134 moves to the first position and is connected to the engaging portion 122 of the door 120, the door 120 cannot be opened even if the door 120 is pulled, that is, the door 120 is not unlocked by an external force, so that the problem that a child accidentally touches a button or the door 120 unlocks the door 120 is fundamentally solved.
