Projection display device, washing machine and control method applied to household appliances

technical field

The invention belongs to the field of household appliances, and in particular relates to a projection display device, a washing machine and a control method applied to household appliances.

Background technique

The display area of the existing washing machine is concentrated on the operation panel, which integrates display and operation on components such as program selection, function setting, and display screen.

Due to the structure of the washing machine, the installation position and size of the operation panel are limited. The limited installation position of the operation panel limits the display area, and the size of the operation panel limits the size of the display area. At present, a display screen is usually used for display. In order to increase the area of the display area, the size of the display screen is increased. However, the larger the size of the display screen, the higher the price, and the size and display content of the display area are limited in order to save costs.

A projection device, a device that projects an image or video onto a screen, is now widely used as a tool. The projector is mainly composed of an optical system, ventilation equipment and circuits. Similar to a slide projector, it also uses the imaging principle of a convex lens to realize the projection function. At present, no projection device is applied to household appliances for switching display.

However, the current display area is relatively single, and the position cannot be adjusted in real time according to the user's operation, and the display area has poor followability, which makes it unsuitable for observation in certain positions and brings inconvenience to the user.

In view of this, the present invention is proposed.
