Description

Door body structure for cleaning machine and cleaning machine

Technical Field

The utility model relates to the technical field of dish washers, in particular to a door body structure for a cleaning machine and the cleaning machine.

Background

At present, a household dish washer on the market is generally provided with an openable door body in front of the dish washer, and the door body is flattened to form a sliding platform of a dish basket of the dish washer. In practical application, the outer surface of the door body is easy to cover with water. For example: after the door body is closed, the inner container of the dish washer forms a sealed cavity so as to spray and clean tableware loaded in the inner container, and the door body prevents water from flowing outwards. When the door body is opened, the flattened door body can form a sliding platform of the bowl basket of the dish washer, so that the bowl basket slides on the door body, but the bowl basket is loaded with the washed tableware, and water on the tableware directly drops on the flattened door body. Therefore, no matter which state the door body is in, water is inevitably accumulated on the door body.

The common door body of the dish washing machine is generally formed by splicing an inner door body and an outer door body, and a seam is easy to exist at the splicing position of the inner door body and the outer door body. Because the surface of the door body is provided with water, the water can easily permeate into the door body from a gap between the inner door body and the outer door body, thereby affecting electric parts such as a control panel and the like arranged in the door body and easily generating electricity-related accidents; or, the switch on the control panel adopts the structure of the key spring, so that the water vapor can erode the spring, and the key is out of order.

In order to solve the problems, a dish washer and a door body thereof disclosed in Chinese patent publication No. CN202220222452.4 (bulletin No. CN 216962393U) comprises a control panel part, an inner door plate part, a water baffle and a sealing element, wherein the inner door plate part covers the control panel part; the water baffle is arranged in the control panel part; the water baffle is provided with a mounting groove; the sealing piece is embedded in the mounting groove of the water baffle and is propped against the inner door plate part. The sealing structure on the door body of the dish washer is improved, so that the technical problem that accumulated water on the door body is easy to infiltrate into the door from a gap formed by splicing door plate pieces, and electric appliance parts arranged in the door body are easy to cause electric accidents is solved.

But only rely on the sealing member to prevent water from entering the inside of the door body, the reliability is lower, because the sealing performance may be reduced after the sealing member is used for a long time, and the sealing member is also crucial to be matched with the door body when being assembled on the door body, and if the sealing member is not tightly matched with the door body, water leakage is still easy to occur.

Disclosure of Invention
