Abstract: A washing machine includes: a cabinet; a tub; a pump for discharging washing water stored in the tub to an outside of the tub; and a valve assembly for circulating washing water discharged from the pump to the tub and discharging washing water to an outside of the cabinet. The valve assembly includes: a valve housing; a first chamber defined inside the valve housing and configured to connect to a circulation flow path for sending washing water to the tub and a drainage flow path for draining washing water to the outside of the cabinet; and a disc valve configured to linearly move inside the first chamber and selectively connect the first chamber to the drainage flow path or to the circulation flow path based on a water pressure applied by washing water discharged from the pump.

Abstract: A washing machine includes: a cabinet; a tub; a pump for discharging washing water received in the tub to an outside of the tub; and a valve assembly for introducing washing water discharged from the pump. The valve assembly includes: a valve housing; a first chamber defined inside the valve housing and configured to connect to a circulation flow path for sending washing water introduced from the pump to the tub and a drainage flow path for draining washing water introduced through the pump to an outside of the cabinet; a disc valve configured to linearly move in a vertical direction inside the first chamber and move upward by a pressure of washing water discharged from the pump; and a weight part disposed above the disc valve and configured to apply a load to the disc valve.
