Document Type and Number:
Japanese Patent JPS5844186
Kind Code:
B2
Abstract:
An automatic ice maker control circuit having an improved tolerance to sense the presence of stuck ice pieces in a predetermined pocket of an ice tray. A solid state temperature sensor and time delay circuit includes an operational amplifier controlled by a temperature sensor in one portion of a bridge network for sensing above or below freezing temperatures in the pocket, depending upon the presence of liquid or a stuck cube respectively, in said sensing pocket. The ice maker is conditioned for immediate harvest after the below freezing temperature is effected in the tray pocket when the sensor senses an above-freezing temperature. The time delay circuit conditions the ice maker for a delayed harvest until the predetermined temperature is effected in the tray sensing pocket if the sensor senses a below-freezing temperature.
