A washing machine including a dissolving unit and a bubble generating unit. The dissolving unit includes a hollow outer body that has an open end, and a hollow inner body that has an open end. The inner body is disposed in the outer body. The gap between the inner and the outer body forms a dissolving flow path. The dissolving unit includes flow paths allowing water to mix with air efficiently as water flows through. The bubble generating unit includes a pressure reduction region to reduce pressures of bubbles. Bubbles can be supplied with washing water either to the upper side or the lower side of the tub.

A washing machine capable of generating and supplying bubbles to laundry during washing and rinsing operations to facilitate removal of detergent and foreign substances from the laundry. A dissolving unit can receive a water supply and contain a volume of air. The dissolving unit provides a water flow path that allows the contained air to dissolve efficiently in the water, thereby providing a water/air mixture to a bubble generating unit. Dissolved air can separate from the water/air mixture in the bubble generating unit and form bubbles, e.g., due to pressure reduction. The bubbles are then supplied to the tub containing the laundry.

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.

A washing machine contains a wash tub, an impeller and a motor. Clothing is put into the tub and the load is detected. Water is added until the water level is below or equal to load height. To begin washing, the impeller drives the clothing to overturn, resulting in generating three types of water flows: agitating flow, enhancing flow and balancing flow. At first, the agitating flow breaks the balance of the load to disperse clothing, then the enhancing flow overturns clothing for washing. Finally, the balancing flow maintains the circulation path for the load balance overturning. Single sequential control or repeatedly alternating cycle control of the three types of water flows can be adopted for washing. The invention can save water, improve washing efficiency and avoid intertwining of clothing, characterized by full-range, thorough, repeated and efficient washing.
