Abstract

Viene descritta una macchina lavatrice, in particolare una lavabiancheria, comprendente un tamburo, nel quale trova posto la roba da lavare, trascinato in rotazione da un motore elettrico, alimentato tramite un dispositivo di regolazione; la caratteristica principale del dispositivo consiste nel fatto che tale dispositivo di regolazione include un sistema di controllo, che in presenza di uno sbilanciamento del carico, provvede a sincronizzare l'istante di lancio della fase di centrifugazione con l'istante in cui il carico sbilanciato si trova in una posizione angolare tale che l'azione della gravità favorisca l'aumento di velocità di rotazione del tamburo.A washing machine is described, in particular a washing machine, comprising a drum, in which there is the stuff to be washed, driven in rotation by an electric motor, powered by an adjustment device; the main feature of the device consists in the fact that this regulation device includes a control system which, in the presence of a load imbalance, synchronizes the launch moment of the centrifugation phase with the instant in which the unbalanced load is it is in an angular position such that the action of gravity favors the increase in the rotation speed of the drum.
