<p>Clothes washing machine provided with a wash tub, a perforated drum arranged therein, a recirculating pump to pump the liquor contained in a conduit which is provided with a pressure switch in its lower portion and is arranged under the tub and directed again toward the interior of the drum. The machine is capable, at least in a rinse, to fill a pre-determined amount of water in the tub, to let the recirculating pump operate for a definite period of time so as to enable said water to be fully pumped into the drum which at the same time is caused to rotate at a low speed, to deliver a signal starting spin-extraction for a pre-defined period of time so as to enable 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 liquor in the tub eventually remains constantly below the lower edge of said drum, such an alternate sequence of recirculation and spin-extraction phases being repeated several times. <IMAGE></p> |
