Abstract

PROBLEM TO BE SOLVED: To efficiently circulate washing water and to improve washing performance without damaging the wash by containing an inner tank for containing the wash inside an outer tank so as to execute watering from an upper part into the inner tank by means of the rotation of the inner tank in configuration and permitting the number of inner tank rotation to be controlled by means of at least two stages. SOLUTION: When the wash and a detergent are thrown-in to the inner tank 2 and an operation is started, water is supplied up till the prescribed water level inside the inner tank 2 by a controller 11. When the inner tank 2 is rotated after that, the water surface of washing water inside the outer tank 1 is elevated between the outer side of the inner tank 2 and the outer tank 1 by stirring force caused by the rotation and a center part is lowered. When the number of inner tank 2 rotation is increased, the water surface between the outer side of the inner tank 2 and the outer tank 1 is more elevated so as to exceed the height of the upper end part of the inner tank 2 so that washing water is watered into the inside of the inner tank 2. Thus, washing water is circulated, the dissolusion of the thrown-in detergent is promoted, the number of inner tank 2 rotation is controlled between high speed and low speed so as to change centrifugal force to be added to the wash and washing performance is enhanced.

As described above, according to the first aspect of the present invention, the inner tub for storing the laundry, the outer tub for storing the inner tub, and the control for controlling the rotation of the inner tub. Means for rotating the inner tub so that water is sprayed into the inner tub from above, and the control means can control the number of rotations of the inner tub in at least two stages. No mechanical force such as friction is applied to the laundry due to the circulation of water, so it is possible to improve the washing performance without damaging the laundry, reduce uneven washing, and reduce the number of rotations of the inner tub. By changing it, the centrifugal force applied to the laundry can be changed, and the detergent component can effectively act on the soil of the laundry, and the cleaning performance can be improved.
