An automatic ice maker for use in freezing compartments of the refrigerators. A planar stop arm is used as an ice cube detecting device for detecting a sufficient ice cubes stored in a bin arranged below a tray for making ice cubes. The stop arm can be swung between the bin for storing therein the ice cubes and the tray in order prevent the ice cubes stored in the bin from being molten by a head radiation from a heater provided on the tray.

Automatic ice maker

An automatic ice making apparatus having a sensor which can detect continuously a temperature of an ice making tray is used as a temperature sensor. The temperature and a temperature variation rate of the ice making tray are detected by an electronic control circuit having a function corresponding to an A/D converter and a microprocessor or the like to determine a freezing state of water. Further, a thermistor is used as the temperature sensor, and by and A/D converter including a microprocessor a water level in the ice making tray is detected and a solenoid valve for determining an amount of supply water is controlled so as to suppress the water amount variation due to a water pressure change or the like.
