Abstract

Macchina lavatrice avente una resistenza elettrica (3) collegabile ad una sorgente di alimentazione (10), attraverso un commutatore controllato dal programmatore (17), per riscaldare un fluido contenuto in una vasca di lavaggio. Un dispositivo di misurazione (13) associato al programmatore (17) comprende una coppia di terminali (11, 12) atti a rilevare, ai capi della resistenza di riscaldamento (3), segnali proporzionali all'effettivo valore ohmico della resistenza stessa, e quindi indicativi della sua temperatura. Il dispositivo di misurazione (13) diseccita la resistenza di riscaldamento (3) quando i segnali rilevati ai propri terminali (11, 12) sono indicativi di una temperatura della resistenza superiore ad un valore predeterminato. Consente una precisa misurazione di temperatura senza impiego di termostati.
