Referring to fig. 1 to 7, a door lock assembly 100 according to an embodiment of the present invention is described, which is suitable for a cooking device such as a microwave oven, an oven, a steaming and baking machine, etc. The door lock assembly 100 will be described in detail below, taking the door lock assembly 100 of the microwave oven as an example.

Referring to fig. 1, the embodiment of the present invention provides a door lock assembly 100, which includes a casing (not shown in the drawings) and a door 110, wherein the casing can be understood as a furnace body of a microwave oven, a heating cavity is provided in the furnace body, an opening communicated with the heating cavity is provided on the furnace body, the door 110 is connected to the furnace body, and the opening can be opened or closed through the door 110.

Referring to fig. 1 and 2, a locking device is installed on the oven body, the locking device includes a lock pin 140 and a damper 130, the lock pin 140 is connected with the damper 130, the lock pin 140 is used for locking the door body 110 on the oven body when the door body 110 is closed, and when the door is opened, the lock pin 140 needs to be unlocked first, so that the door body 110 can be opened, the difficulty of opening the door body 110 is increased, children are prevented from easily opening the door body 110 of the microwave oven and contacting with heated food to be scalded, and an effective protection effect is achieved. Specifically, the lock pin 140 is movably installed in the furnace body, a lock groove (not shown in the drawings) matched with the lock pin 140 is arranged on the door body 110, and when the door body 110 is closed, the lock pin 140 can penetrate through the furnace body and correspondingly inserted into the lock groove of the door body 110, so that the door body 110 is locked; the door 110 can be opened only by moving the lock pin 140 out of the lock groove, and compared with the conventional microwave oven, the locking device in the embodiment has the function of a child lock, and the door opening action can be performed only by releasing the locking of the child lock, so that the door 110 is not easy to open by children, and the difficulty in opening the door 110 is improved.

Referring to fig. 2, it can be understood that, in a natural state, the latch 140 is in a state of extending out of the oven body, and when the door body 110 is closed, the latch 140 can be inserted into the latch groove, so as to lock the door body 110; when the door is opened, the lock pin 140 is pushed to move towards the direction far away from the lock groove, so that the lock pin 140 is separated from the lock groove, and the purpose of unlocking is achieved. The damper 130 is connected with the lock pin 140, after the lock pin 140 moves out of the lock groove, the damper 130 can push the lock pin 140 to move towards the lock groove, and damping effect is generated on the movement of the lock pin 140, so that the movement speed of the lock pin 140 is reduced, the time for locking the door body 110 by the lock pin 140 is delayed, namely, the lock pin 140 can slowly move to reset, and a certain interval time is provided between the unlocking and the locking recovery, therefore, enough time can be provided for opening the door body 110 before the lock pin 140 locks the door body 110, namely, the door body 110 is opened after the unlocking, the door opening operation can be completed by one hand, and the door body 110 is not required to be opened by one hand while the other hand is used for opening the door body 110, so that the operation is more flexible and convenient, safe and reliable.

The specific operation steps are that the lock pin 140 is pushed to retract the lock pin 140 into the shell, then the door body 110 is closed, and the lock pin 140 slowly moves and is inserted into the lock groove, so that the door body 110 is automatically locked after being closed; when the door body 110 needs to be opened, the lock pin 140 is pushed, and the door body 110 can be opened after the lock pin 140 moves out of the lock groove, so that the operation is simple and convenient. The operation of opening the door 110 may be understood as a door opening operation by a door opening button or directly pulling the door 110. It should be noted that the damper 130 adopted in the embodiment may be a hydraulic damper, a spring-type damper, or the like, and can effectively prolong the time for locking the door body 110, and the movement time of the lock pin 140 is prolonged by the damper 130 within a range of 2 seconds to 10 seconds according to the use requirement of the actual product, which is not described herein again.
