Abstract
Dei sensori della distanza e degli elettromagneti sono montati sulla vasca interna della lavatrice ed altri elettromagnetici sono montanti sull'involucro esterno della stessa. Quindi, in modo da impedire le vibrazioni generate sulla vasca interna durante le operazioni di lavaggio e di disidratazione, i sensori della distanza quantificano le vibrazioni, e dei dispositivi attivi di attenuazione e delle parti del segnale di controllo generano dei segnali di controllo, cosicchè quando la vasca interna e l'involucro esterno si avvicinano uno rispetto all'altra oltre la distanza di riferimento, gli elettro magneti generano una forza repulsiva uno rispetto all'altro mentre quando la vasca interna e l'involucro esterno si allontanano l'uno rispetto all'altro oltre la distanza di riferimento, gli elettromagneti generano una forza di attrazione uno rispetto all'altro, in modo che le vibrazioni prodotte sulle vasca interna vengono ridotte.(FIG. 2)
