Abstract: 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.
