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.Centrifugation control device for laundry washing machine, designed to end this phase when the water contained in the laundry has been completely extracted from the tub, thus optimizing the duration of the washing cycle. Device including an electronic counter (4) and an electronic comparator (5), connected with the microcontroller (1) controlling the washing cycle set together with the drain pump (3) and a pressure switch (2), designed to determine a predetermined filling level of the water in the tank of the The counter (4) measures the time between the stopping of the drain pump (3) during the final centrifugation and the achievement of the pre-set level detected by the pressure switch (2). If this time is less than a predetermined reference time (Trif), the drain pump (3) is reset, otherwise this drain pump is kept off and the centrifugation finished.
