Abstract: A control knob for an appliance includes a base having an axially-operated switch. An outer control assembly is rotationally and axially operable with respect to the base. An inner display assembly is rotationally fixed with respect to the base and axially fixed with respect to the outer control assembly. The inner display assembly is biased toward an extended state and is axially operable to a selection state that engages the axially operated switch.

Abstract: The invention relates to a knob structure for a washing machine and a washing machine. The knob structure includes a knob component, a display component, a pressing component, and a PCBA board. The knob component includes a knob rotating seat, a fixed body and a knob decorative ring. The upper part of the knob rotating seat is provided with a receiving groove 1, the middle section is provided with a receiving groove 2, and the lower end is provided with a receiving groove 3; the inner peripheral wall of the receiving groove 2 is provided with a plurality of uneven grooves distributed uniformly. A metal conductive sheet A is installed at the bottom of the second receiving groove. A metal conductive sheet B, a metal conductive sheet C, and a metal conductive sheet D are mounted on the lower end of the fixed body. The display assembly includes a display base, a display module, and a glass lens. The pressing component includes a knob fixing bracket, a switch button and a rotary sound generator.
