Abstract

Un circuit pour commander un appareil à fabriquer de la glace automatique d'un réfrigérateur (10) fait fonctionner l'appareil à l'aide d'un système d'interrupteur de lumière (18, 20). Une source de lumière pulsée est coupée lorsque la glace a atteint un niveau déterminé (12) dans le bac à glace (16). Le circuit utilise des composants qui activent l'appareil dès que la source lumineuse est détectée pendant une période prédéterminée et qui le désactivent lorsque la source n'est pas détectée pendant une autre période.A circuit for controlling an apparatus for making automatic ice from a refrigerator (10) operates the apparatus using a light switch system (18, 20). A pulsed light source is cut off when the ice has reached a determined level (12) in the ice bin (16). The circuit uses components that activate the device as soon as the light source is detected for a predetermined period and deactivate it when the source is not detected for another period.
