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.

Disclosed is a washing machine. The washing machine comprises an impeller, a decelerating clutch and an impeller connection assembly, wherein the decelerating clutch has a rotary shaft; and the impeller connection assembly is clamped and clamped and fixedly connected to the rotary shaft, so that the impeller is clamped and fixedly connected to the rotary shaft in a detachable way, thereby reducing the difficulties of the assembly and disassembly of the impeller, and prolonging the service life of the washing machine.

A washing machine may include a static wash tub, a rotatable vertical axis wash basket in the static wash tub, and a drive motor for rotating the wash basket. A closure may direct wash liquid from the wash basket to a catch basin. A flange may be attached to the closure so that an unattached edge ends within the catch basin. The unattached edge may end below the surface of a first volume of wash liquid to minimize migration of wash liquid and/or vapor from the washing machine. The unattached edge may end above the surface of a second volume of wash liquid less than the first volume to minimize agitation of wash liquid in the catch basin.

An agitation element includes a base, a shaft extending from the base generally along a vertical direction, at least one fin, and a plurality of ribs. Each of the plurality of ribs extends from the base and radially outward from the shaft. Each of the plurality of ribs includes a radially outward portion, the radially outward portion including two opposing entirely convex sidewalls and defining a maximum width and a maximum height, wherein a ratio of the maximum width to the maximum height is between 0.8 and 1.2. Each of the plurality of ribs further includes a radially inward portion, the radially inward portion including two opposing sidewalls.

A laundry machine and a washing process allow the storage of water from prior washes, in order to minimize the consumption of water destined for laundry washing. According to an embodiment, the laundry machine includes an impeller (201); a wash tub (202); a mechanical and/or electric drive element of the impeller and of the tub; and at least a tank (203) encircling the wash tub. There is additionally a reservoir (300) in fluid communication (250) with the tank and disposed below the tank and the wash tub and encircling, at least partially, the mechanical and/or electric drive element of the impeller and the tub.

The present invention comprises: an inner tub for receiving laundry; a first pulsator rotatably disposed in the inner tub; a body which has a ring shape and is coupled to the first pulsator; and a second pulsator having a cover which is disposed on the body, wherein each of the body and the cover has multiple arc-shaped members arranged in order along a circle, thereby facilitating the service work by the second pulsator.

A washing machine includes an auxiliary washing unit. When an inner tank is rotated during a washing cycle or a rinsing cycle, laundry experiences direct impact from an impact projection member of a rotator assembly of the auxiliary washing unit, thereby improving washing performance by virtue of the rubbing caused by such impact.
