The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0036] like Figure 1 to Figure 7 As shown, this embodiment provides a door body structure, which includes a door body and a door hinge 2, the door body includes a metal main door body 11 and a plastic outer door frame 12 fixed to each other; the door hinge 2 includes a first connecting part 21 and a second connecting part 22, the first connecting part 21 and the second connecting part 22 are pivotally connected, the first connecting part 21 is fixed to the main door body 11, and the second connecting part 22 is used to be fixed to the box body, and the door hinge 2 realizes the pivot connection between the door body and the box body. When the cooking appliance provided with the door body structure is working, since the main door body 11 is made of metal material, it has sufficient strength and is not easily deformed and damaged under the action of external force. Therefore, the first connection part 21 of the door hinge 2 is fixedly connected to the main door body 11, and the second connection part 22 is fixedly connected to the box body. While realizing the pivot connection between the door body and the box body, the stability of the assembly between the door body and the box body is guaranteed, and the gap between the door body and the box body does not gradually increase with long-term use, thereby avoiding the leakage of microwaves and steam generated by the cooking appliance when it is working, and ensuring the safety of the user.
[0037] Optionally, the door hinge 2 further includes a quick release portion 23, the quick release portion 23 is fixedly connected to the main door body 11, and the quick release portion 23 is clamped with the first connection portion 21. In this embodiment, the above arrangement can improve the assembly efficiency of the quick release portion 23 and the first connection portion 21, thereby improving the assembly efficiency of the door body and the box body, and on the other hand, compared with the use of bolts for fixing, the clamping method of the quick release portion 23 and the first connection portion 21 can enhance the stability of the structure and prevent the connection between the quick release portion 23 and the first connection portion 21 from loosening.
[0038] like Figure 4-Figure 7As shown, optionally, the quick-release part 23 includes a body 231 and a lock buckle 232. The body 231 is fixedly connected to the main door body 11. The body 231 is provided with a fixing groove 2311 and a lock hole 2312. The axis of the fixing groove 2311 and the axis of the lock hole 2312 intersect. The first connecting part 21 is inserted into the fixing groove 2311 and a recessed slot 211 is provided at a portion opposite to the lock hole 2312. The lock buckle 232 is inserted into the lock hole 2312 and the slot 211 in sequence.
