Abstract
A clothes washing machine and method wherein a washing liquid is ejected and circulated through a suction pump in a connecting hose from an outer tub, with the recirculated washing liquid being sprinkled all over the clothes through a sprinkling port. An amount of washing liquid to be supplied into the washing tub is set to be about three to eight times larger than that of the clothes to be washed in a weight ratio and washing is performed by carrying out a sprinkling or spraying of the washing liquid on the clothes. By setting an amount of washing liquid supplied to the washing tub to be as small as three to eight times the amount of clothes to be washed in a weight ratio, the clothes are prevented from floating upon the washing liquid and, accordingly, it is possible to promote a friction, expansion, and contraction action of the clothes and to increase a direct frictional effect caused by an agitator of the washing machine.
