  • Publication number: 20180291550
    Abstract: A washing machine comprises at least two sets of washing devices and a display control panel, wherein the display control panel includes at least two different independent display interfaces, with one display interface corresponding to one set of washing device. The display control panel of the washing machine can display at least two colors, with one display interface corresponding to one color. After the washing machine is initialized, one set of the washing device or the combination of the at least two sets of washing devices are arbitrarily selected, and the display interfaces corresponding to different control processes of the selected washing device display different brightness. Through arranging at least two colors on the display screen of the washing machine, different control processes of the washing machine can be realized through the switching between different colors and different brightness, thereby satisfying the individual requirements of more users.
