Abstract (en)
[origin: EP0736625A1] Clothes washing machine, typically a top-loading one, provided with a washing tub, a cylindrical drum (2) adapted to hold the washload (1) which is loaded thereinto through a lid (3) closing an aperture provided in a portion of the surface of the drum, a plurality of rib-like elevators (4) arranged on the inner surface of said drum, the latter having no mass-balance weight for balancing the weight of the lid. The machine is provided with means adapted to identify the position of the loading lid, to allow the drum to go on rotating for a pre-determined period of time at an adequately low revolution speed so as to allow the washload to collect on the bottom of the drum and to allow said drum to start spinning when said means indicate that the loading lid has reached its upper position. A variant thereto consists in preceding spin-extraction with a phase in which the drum is allowed to rotate at a speed which, although generally low, is adequately high to enable the washload to distribute along the inner periphery of the drum, while starting the spin-extraction phase as soon as unbalance is detected to lie at a value which is lower than a pre-determined one. <IMAGE>
