Abstract

Macchina lavabiancheria particolarmente domestica, dotata di una vasca di lavaggio, di un condotto di scarico posto sotto detta vasca, di un sensore analogico di pressione atto a misurare la pressione esistente in un livello inferiore di detto condotto, di una pompa di scarico atta ad eliminare all'esterno il liquido contenuto in detto condotto, in cui durante la fase di centrifugazione la pompa di scarico viene arrestata per intervalli regolari, alla ripresa del funzionamento di detta pompa di scarico viene iniziato un periodo di attesa alla fine del quale viene rilevata detta pressione, detta successione di modalità funzionali essendo eseguita una pluralità di volte, la differenza di pressione essendo calcolata sui valori di pressione rilevati in due istanti successivi di rilevazione per ciascuna di detta successione e confrontata con un valore predeterminato.Particularly domestic washing machine, equipped with a washing tank, a drainage duct located under said tub, an analog pressure sensor suitable for measuring the pressure existing in a lower level of said duct, a drain pump designed to eliminate outside the liquid contained in said duct, in which during the centrifugation phase the drain pump is stopped for regular intervals, when the operation of said drain pump resumes a waiting period is started at the end of which said pressure is detected , said sequence of functional modes being performed a plurality of times, the pressure difference being calculated on the pressure values detected in two successive instants of detection for each of said sequence and compared with a predetermined value.
