The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

A door assembly of a cooking appliance 100 according to an embodiment of the present application is described below with reference to fig. 1 to 9.

As shown in fig. 1 to 3, the door assembly of the cooking appliance 100 includes a door body 110, a latch hook 120, and a reset member 140.

The door body 110 is configured to be opened and closed on the main machine 130 of the cooking appliance 100 to form a cooking cavity 131 with the main machine 130 of the cooking appliance 100, so as to perform functions of heat preservation and heat insulation. In some examples, the door 110 may further be provided with a perspective window to facilitate viewing the state of food in the main body 130; the door body 110 may also be provided with a control panel for controlling the operation of the electric appliances in the host 130; door body 110 can also be provided with a door handle, which can facilitate the user to pull door body 110.

The latch hook 120 may be used to lock the door body 110 and the host 130, and the latch hook 120 may be made of metal or plastic, for example, in some embodiments, the latch hook 120 is made of plastic, wherein the plastic may include, but is not limited to, PP (Polypropylene), POM (polyoxymethylene), PC (Polycarbonate).

The latch hook 120 is rotatably mounted to the first frame 114 of the door body 110 about a first axis between a first position, in which the latch hook 120 is adapted to be locked with the main body 130 of the cooking appliance 100, and a second position, in which the latch hook 120 is adapted to be unlocked with the main body 130 of the cooking appliance 100.

The latch hook 120 is rotatably mounted on the first frame 114 of the door body 110 around the first axis, the first frame 114 can be connected with the main machine 130 of the cooking appliance 100, and when the latch hook 120 moves to the first position, the latch hook 120 can be locked and limited with the main machine 130 of the cooking appliance 100, and at the moment, the door assembly is in a locked state and cannot be opened; in the case that the latch hook 120 is moved to the second position, the latch hook 120 is unlocked and disengaged from the main body 130 of the cooking appliance 100, and the door assembly is in an unlocked state and can be opened.

In the present embodiment, at least a portion of the latch hook 120 extends from the back plate 112 of the door body 110, and the first axis is parallel to the length direction of the first frame 114.

The back plate 112 of the door body 110 is a panel of the door body 110 facing the main machine 130, at least part of the latch hook 120 extends out of the back plate 112 of the door body 110, the part of the latch hook 120 extending out of the back plate 112 is used for locking and limiting with the front plate 132 of the main machine 130, the front plate 152 of the main machine 150 is used for abutting against the back plate 112 of the door body 110, and the latch hook 120 is arranged to extend out of the back plate 112 of the door body 110, so that the front and side surfaces of the door body 110 are not protruded, and the front and side surfaces of the door body 110 are more attractive. In addition, after the door body 110 is opened, since the side edge of the door body 110 does not have a protruding portion, the latch hook 120 is prevented from accidentally injuring a human body. Here, the front surface of the door body facing the user is a front surface, the four surfaces surrounding the front surface are side surfaces, and the opening of the door body facing the user is a side surface.

The first axis is parallel to the length direction of the first frame 114, so that when the latch hook 120 rotates around the first axis, the portion of the latch hook 120 for locking with the host 130 can move along the direction close to the frame, so as to lock with the front plate 132 of the host 130, and the portion of the latch hook 120 for locking with the host 130 can move along the direction away from the frame, so as to unlock with the front plate 132 of the host 130.
