Abstract

La presente invenzione si riferisce ad un apparato elettrodomestico a controllo elettronico, il cui funzionamento risente delle condizioni esterne, in particolare un frigorifero, comprendente un primo scomparto (cella dei cibi freschi), destinato a contenere ciò su cui si esplica l'azione dell'apparato (cibi), un primo dispositivo agente attivabile e disattivabile (compressore), un dispositivo di regolazione manuale per regolare l'effetto dell'apparato ed un dispositivo elettronico digitale di controllo che gestisce il funzionamento dell'apparato; la caratteristica principale dell'apparato secondo l'invenzione consiste nel fatto che esso comprende un sensore, sensibile ad una condizione esterna importante per il funzionamento dell'apparato, e collegato a detto dispositivo di controllo, e dal fatto che quest'ultimo è associato ad una memoria non volatile, nella quale sono contenute tabelle, indicanti, per ogni posizione del dispositivo manuale di regolazione e per ogni valore fornito dal sensore, e compreso in un campo prefissato di valori, il valore ottimale della durata di attivazione di detto primo dispositivo agente.
