Abstract

Dispositivo di controllo della fase di centrifugazione per macchina lavatrice di biancheria, atto a terminare questa fase quando l'acqua contenuta nella biancheria è stata completamente estratta dalla vasca, ottimizzando così la durata del ciclo di lavaggio.Dispositivo comprendente un contatore elettronico (4) ed un comparatore elettronico (5), collegati col microcontrollore (1) di controllo del ciclo di lavaggio impostato assieme alla pompa di scarico (3) e ad un pressostato (2), atto a determinare un livello di riempimento prestabilito dell'acqua nella vasca della macchina.Il contatore (4) misura il tempo intercorrente tra l'arresto della pompa di scarico (3) durante la centrifugazione finale ed il raggiungimento del livello prestabilito rilevato dal pressostato (2). Se tale tempo è inferiore ad un tempo di riferimento prestabilito (Trif), viene ripristinata la pompa di scarico (3), altrimenti tale pompa di scarico viene mantenuta disinserita e la centrifugazione terminata.
