Improvement in the dynamic balancing method for a washing machine

摘要

Clothes washing machine provided with an oscillating washing assembly comprising a rotating drum capable of being driven at various rotating speeds and provided with a plurality of annular hollow bodies secured to said drum and a plurality of moving masses capable of freely displacing within said hollow bodies, wherein before at least a spin-extraction phase the drum is driven to rotate in a continuous manner at a variable, relatively low speed which is lower than the resonance frequency of said oscillating washing assembly, but anyway adequate in view of causing the washload in the drum to keep adhering against the inner peripheral surface of the drum. As soon as said moving masses succeed in distributing themselves in such a manner that their center of gravity locates itself in a position which is substantially opposite to the unbalance condition of the washload, the drum is started to rotate at the desired spin-extraction rate. <IMAGE>
