Abstract
A clothes washing machine is provided with a wash tub and a perforated drum arranged therein. A recirculating pump pumps liquid contained in a conduit provided with a pressure switch in its lower portion, arranged under the tub, and directed again toward the interior of the drum. The machine is capable, at least in a rinse cycle, of filling a predetermined amount of water into the tub, to let the recirculating pump operate for a definite period of time so as to enable the water to be fully pumped into the drum. At the same time, the drum is caused to rotate at a low speed. A signal starting spin-extraction for a pre-defined period of time enables a lower water level to be restored in the tub. The initially filled-in water is let into the tub in such an amount that the upper edge of the liquid in the tub eventually remains constantly below the lower edge of the drum, such an alternate sequence of recirculation and spin-extraction phases being repeated several times.
