At present, infrared sensing is used to collect the user's operation signal. Although this method can easily detect the user's operation signal, this method requires no obstruction in the infrared sensing detection range. If there is obstruction blocking, it will affect the detection. Signals, so some devices can not be significantly modified to meet the infrared sensing requirements of the equipment, the use of infrared sensing methods will not be optimal. If the button mode is adopted, the display area is lost in operability.

The touch operation device is added in the displayed area, and the display content can be displayed to the display area convenient for the user to view and operate, and when the user performs the touch operation in the display area, the operation signal of the user is collected and analyzed to determine the operation of the user. Behave and respond. The door cover is a visual component that directly faces the user of the washing machine and can be used to set the display area. If the door cover is transparent, the user can observe the internal operation of the washing machine at any time, but the display content in the display area has low definition, which affects the user to observe at a distance.
