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

Embodiment Construction
[0023] At present, the angle between the lid of most washing machines and the horizontal direction is controlled to be equal to or slightly greater than 90 degrees. By controlling the position of the center of gravity, the lid is in an upright state after opening. In this way, the lid is very easy to close automatically, and the lid will hit the base when it is closed. Noise is generated, and it is inconvenient to take clothes. In order to solve the above problems, the present invention adopts a positioning structure on the hinge of the washing machine after the lid is opened, so that the lid is in a stable clamping state when it is fully opened, and will not be closed freely.
[0024] The cover opening and closing structure of the washing machine according to the present invention, the cover opening and closing structure includes a cover, a base and a control device, the turning shaft 12 of the cover 3 is installed on the base 4, and the control device It includes a chute 1 an...

The invention relates to a cover opening and closing structure of a washing machine and a washing machine. The cover opening and closing structure includes a cover, a base and a control device. The turning shaft of the cover is installed on the base. The control device includes a slide Slot and elastic support, the chute is set on the turning shaft of the cover along the direction of rotation, the lower end of the elastic support is installed on the base, and the upper end is slidably supported in the chute, and a limiting groove is arranged in the chute, elastic The support piece slides into the limiting groove to prevent the automatic closing of the cover body after opening. When the cover is completely closed, the cover is in a stable clamping state, and it takes a little force to open the cover, which can avoid the collision between the cover and the base to generate noise caused by the vibration of the washing machine during dehydration. When the cover is fully opened, the cover is in a stable clamping state, and the cover will not be easily closed, which is convenient for users to take and place clothes, and can also avoid the impact and collision caused by the automatic closing of the cover to the base.
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...
