Problems solved by technology

In the initial stage of opening and closing the cover, the attenuation force of the buffer damper has no effect on the rotation of the cover due to the existence of the free rotation range, so in the initial stage of the cover opening and closing operation, the user only needs to pass the The opening and closing operation can be carried out by resisting the force of the load such as the toggle spring and the self-weight of the cover. The opening and closing operation is very convenient, but it cannot solve the problem that the cover is easy to close automatically after opening

Abstract

The invention relates to a washing machine cover opening and closing structure and a washing machine. The cover opening and closing structure comprises a cover, a base and a hinge device, the hinge device comprises a fixing part and a rotating part, the fixing part is installed on the base, the rotating part is installed on the cover, the rotating part is rotatably arranged outside the fixing part in a sleeving mode, the periphery of the fixing part is provided with grooves / convex ribs in the axial direction, and the inner circumference of the rotating part is provided with convex ribs / grooves in the axial direction. When the cover is completely closed, the cover is in a stable clamping state, the cover can be opened by slightly exerting a person himself / herself, and the situation that when dehydration is conducted, the washing machine shakes to cause collision between the cover and the base to generate noise can be avoided. When the cover is completely opened, the cover is in a stable clamping mode, the cover cannot be closed easily, a user can pick and place clothes conveniently, and the situation that the cover is automatically closed to cause impact and collision to the base can be avoided.

Description

technical field [0001] The invention relates to the field of washing machines, in particular to an opening and closing structure of a washing machine cover and the washing machine. Background technique [0002] Most of the washing machines with the cover on the market currently adopt the method of controlling the angle between the cover and the horizontal direction at greater than 90 degrees after the cover is opened. By designing the position of the center of gravity after the cover is opened, the cover is opened to be in an upright state. In this way, the cover is easy to close automatically after opening, and it is inconvenient to take clothes; [0003] 200910118744.2 provides a washing machine cover structure that does not produce impact sound when opening and closing, and the washing machine cover can be opened and closed smoothly. ; a toggle spring whose applied force can be switched in the opening or closing direction of the cover; and a rotary buffer damper that att...
