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 10.

As shown in fig. 1 to 3, the door assembly of the cooking appliance 100 includes a door body 110, a latch hook 120, a slider 130, and a reset member 140.

The door body 110 is configured to be opened and closed on the main machine 150 of the cooking appliance 100 to form a cooking cavity 151 with the main machine 150 of the cooking appliance 100, and can 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 status of food in the main unit 150; the door body 110 may also be provided with a control panel for controlling the operation of the electric appliances in the host 150; 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 150, 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 on the first frame 114 of the door body 110 between a first position and a second position around the first axis, the latch hook 120 is adapted to be locked with the main machine 150 of the cooking appliance 100 in the first position, and the latch hook 120 is adapted to be unlocked with the main machine 150 of the cooking appliance 100 in the second position.

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 150 of the cooking appliance 100, when the latch hook 120 moves to the first position, the latch hook 120 can be locked and limited with the main machine 150 of the cooking appliance 100, and at the moment, the door assembly is in a locked state and cannot be opened; when the latch hook 120 is moved to the second position, the latch hook 120 is unlocked and disengaged from the main unit 150 of the cooking appliance 100, and the door assembly is in an unlocked state and can be opened.

In this embodiment, at least a portion of the latch hook 120 protrudes from the back plate 112 of the door body 110.

The back plate 112 of the door body 110 is a panel of the door body 110 facing the main machine 150, 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 152 of the main machine 150, 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.

The sliding block 130 is slidably connected to the door body 110, and the sliding block 130 abuts against the latch hook 120 to drive the latch hook 120 to rotate from the first position to the second position.

Wherein the slider 130 is at least partially extended out of the door body 110 for manual operation.

The reset element 140 is elastically connected between the latch hook 120 and the door body 110, and the reset element 140 is used for driving the latch hook 120 to maintain the first position.

The reset member 140 is elastically coupled between the latch hook 120 and the door body 110 to apply an elastic force to the latch hook 120, so that the latch hook 120 is maintained at the first position. When the hand leaves the operation section, the latch hook 120 returns to the first position under the driving of the reset element 140, and when the door body 110 is closed, the latch hook 120 can be locked with the host 150 of the cooking utensil 100, so as to fix the door assembly.

It should be noted that, the latch hook 120 of the present application may be a safety lock of the cooking apparatus 100, that is, the latch hook 120 is a first lock of the cooking apparatus 100, a user may not release the first lock by directly pulling a door, and the cooking apparatus 100 itself has an elastic door lock, which is a second lock of the cooking apparatus 100, and the user may release the elastic door lock by pulling a door handle outwards with a smaller force.

In actual implementation, the latch hook 120 is kept at the first position by the force of the reset member 140, as shown in fig. 7 and 8, and the latch hook 120 is locked with the host 150, so that the door assembly cannot be opened. When the door is opened, the slider 130 needs to be manually pushed, and the slider 130 drives the latch hook 120 to rotate to the second position, so that the latch hook 120 and the host 150 are in an unlocking state, as shown in fig. 9 and 10, and the first unlocking is completed. And then the door assembly is pulled to be separated from the host 150, so that the second unlocking is realized, and after the unlocking is performed through two operations, the door assembly completes the opening action. When the door is closed, the door assembly is closed on the host 150, the latch hook 120 is restored to the first position under the action of the reset member 140 and is locked with the host 150, and the door assembly cannot be opened, so that the door assembly is closed.

According to the door assembly provided by the embodiment of the application, the door assembly can be locked with the main machine 150 of the cooking utensil 100 through the lock hook 120 and the reset piece 140, the lock hook 120 is controlled to be unlocked by the control slide block 130 when the door is opened, the door assembly is pulled to be separated from the main machine 150, the door assembly can be opened through two operations, the door assembly can be prevented from being opened through false touching by children, the risk that the children are scalded by high-temperature food inside the cooking utensil 100 or dangerous articles are put into the cooking utensil 100 is reduced, and the opening and closing operations are simple.
