A predetermined amount of water and detergent are put in, and the clothes and water are stirred by rotating the pulsator to dissolve the detergent and act on the stains on the clothes while causing friction between the clothes or washing with the clothes. The dirt was removed by rubbing the inner wall surface of the dewatering tank and the surface of the pulsator.

[0003] In such a washing machine of the stirring method, there is a problem that the clothing surface is fluffed or frayed due to friction applied to the clothing, or the clothing is entangled with each other and a tensile force acts to cause elongation. Was. Further, when the agitation force is reduced to reduce the frictional force of the clothes, there is a problem that the ability of the washing liquid to pass through the surface of the clothes is reduced, and the washing performance cannot be sufficiently secured.

Further, from the viewpoint of resource saving and energy saving such as water saving and detergent saving, in the pulsator type washing machine, about 40 liters to 60 liters of water per washing varies depending on the amount of clothes, and the amount of water. Requires a certain amount of detergent corresponding to the
There is a problem that a large amount of water is required from 180 liters to 180 liters.

For this reason, a washing machine as shown in FIG. 10 has recently been proposed. Hereinafter, the configuration will be described.
