The present disclosure provides a household appliance and a control assembly which includes a control panel, a display screen and a power switch. The display screen is arranged on the control panel and can move relative to the control panel. The power switch is connected to the control panel and/or the display screen for controlling the power-on and power-off of the household appliance. When the display screen is pressed, the display screen moves relative to the control panel and controls the power-on or power-off of the power switch. By pressing the display screen to control the power-on and power-off of the power switch, a complete power-off can be achieved to eliminate the drawbacks of weak power and incomplete power-off of the touch-sensitive power switch, and the arrangement of a power switch key is omitted, therefore the operation and the overall appearance of the household appliance is simplified.
