Abstract
La presente invención se refiere a un circuito eléctrico para utilizarse en un aparato de refrigeración que tiene un dispositivo para hacer hielo, un depósito para hielo, para recibir el hielo producido por el dispositivo para hacer hielo, controlando dicho circuito eléctrico al dispositivo para hacer hielo, para provocar que éste produzca hielo cuando el hielo acumulado en el depósito está por debajo de un nivel predeterminado, caracterizado porque comprende: una fuente de luz, un perceptor sensible a la luz separado de la citada fuente de luz, de manera que cuando el hielo esté por arriba de un nivel predeterminado, se interrumpe la trayectoria de la luz entre la fuente de luz y el perceptor sensible a la luz, produciendo éste una corriente proporcional al nivel de luz que recibe, un convertidor de corriente a voltaje que recibe una señal de corriente del perceptor sensible a la luz y que convierte la señal a una señal de voltaje, detectores de pico para detectar los picos de la señal de voltaje del convertidor de corriente a voltaje, detectores de umbral para hacer pasar la señal del detector de pico solamente si la señal excede de un umbral predeterminado y retrasadores del tiempo que proporcionan una salida que controla el aparato para hacer hielo, solamente después de que exista la señal del detector del umbral para durante por lo menos un primer tiempo predeterminado, de manera que cuando el hielo está por debajo de un nivel predeterminado para dicha primera duración predeterminada, dichos retrasadores del tiempo activan el aparato para hacer hielo, manteniendo además los retrasadores de tiempo a dicha salida hasta que no exista la señal del detector de umbral para una segunda duración predeterminada, de manera que cuando el hielo está por arriba de dicho nivel predeterminado para el citado segundo período predeterminado, los retrasadores de tiempo desactivan el aparato para hacer hielo.
