Abstract
A washing machine capable of generating bubbles from a water/air mixture and supplying bubbles to the tub to facilitate removal of residual detergent or the like from laundry during washing or rinsing operations. The washing machine has a dissolving unit with an air supply check valve and can receive air from outside of the dissolving unit in accordance with a pressure in the dissolving unit. Air contained in the dissolving unit can be dissolved in water contained therein to produce water/air mixture. A bubble generating unit receives the water/air mixture from the dissolving unit and generates bubbles as the mixture passes along a water flow path and a pressure reduction region in the bubble generating unit.
