Example one

As shown in fig. 1 to 4, the present embodiment provides a door mechanism, which can be applied to household appliances such as a dishwasher and a disinfection cabinet, wherein the door mechanism includes a door body 1 and an operating device 2 disposed on the door body 1, the household appliance includes a body with a front opening, the door mechanism is disposed at the front opening of the body, the door body 1 can selectively open or close the front opening, and the operating device 2 is used for controlling the operation of the household appliance. The door mechanism can open or block the inner cavity opening of the household appliance, and meanwhile touch control over the household appliance is achieved.

The present embodiment takes the application of the door mechanism to a dishwasher as an example, and describes the specific structure of the door mechanism. It is understood, however, that the type of the household appliance and the specific structure of the body do not impose limitations or alterations to the mounting structure of the operating device 2 and of the operating device 2 on the door body 1, i.e. the application of the door mechanism to other household appliances can be referred to its application to dishwashers.

It is worth explaining that, the door body 1 in this embodiment can be hinged on the machine body, and also can be arranged on the machine body in a drawable manner, and the utility model discloses do not do the restriction to the concrete connection form of door body 1 and machine body. Meanwhile, the directions of front, back, left, right, etc. referred to hereinafter are all referred to as the orientation of the household appliance with respect to the user when in use, i.e., the front side refers to the side facing the user, the back side refers to the side facing away from the user, and the left-right direction refers to the side from the left hand to the right hand of the user.

In the present embodiment, the door body 1 has a mounting groove 118 with a front opening, and the manipulation device 2 is slidably mounted to the door body 1 in the front-rear direction to slidably switch the manipulation device 2 between the first state and the second state. The embodiment provides a door mechanism and dish washer, through with controlling device sliding set up in the mounting groove, can adjust the position of controlling device for the door body to can make controlling device relative door body slide to first state or second state according to user's user demand, improve controlling device's use flexibility and convenience.

In the embodiment, a handle structure is formed on the door body 1 or the operating device 2, when the operating device 2 is in the first state, the operating device 2 is at least accommodated in the installation groove 118, and the handle structure is concealed in the installation groove 118 and is shielded by the front side surface of the operating device 2; when the control device 2 is in the second state, the handle structure is exposed.

That is, the door mechanism provided in this embodiment, the movement of the control device 2 between the first state and the second state, can make the buckle handle structure selectively hide or expose outside the user's view: when the handle structure is not needed, the control device 2 can be in the first state, so that the handle structure is hidden in the mounting groove 118, the problems of poor door mechanism aesthetic property caused by the handle structure being exposed out of the visual field of a user and easiness in scratching the user caused by the handle structure being protruded outwards are avoided, and the appearance aesthetic property of the door mechanism is improved; when the door opening and closing mechanism with the buckle structure is needed, the control device 2 can slide to the second state, the buckle structure is exposed, and a user can control the door body 1 through the buckle structure, so that the door body 1 can be opened or closed, and the operation convenience of the door body 1 is ensured; meanwhile, the structure of the handle does not occupy the space on the outer surface of the door body 1, so that the arrangement of the handle structure cannot interfere with the arrangement of the control device 2 on the door body 1, the probability of interference between the handle structure and the control device 2 is reduced, and the layout rationality of the control device 2 is improved.

In other embodiments, the top of the control device 2 has a control surface, and the control surface is located in the mounting groove 118 when the control device 2 is in the first state, and extends out of the mounting groove 118 when the control device 2 is in the second state. That is, in this embodiment, the sliding switching of the operating device 2 between the first state and the second state can make the operating surface be selectively hidden into or exposed out of the installation slot: namely, when the user does not need to use the control screen, the control surface is positioned in the mounting groove 118 to protect the control surface, so that the control surface is prevented from being damaged due to external collision or impact, and the invasion of oil stains, impurities and the like to the control surface is reduced; when a user needs to use the control surface, the control surface is exposed, and the normal use of the control device 2 is ensured.
