Abstract:
An automatic ice making apparatus for use in a home refrigerating box comprising a water supply mechanism, an ice making tray, an ice discharging mechanism, a heater for separating ice, a temperature sensor for the ice making tray, an amount of stored ice detecting mechanism and an electronic control circuit for controlling the above mentioned components, wherein said components other than said water supply mechanism are positioned in a freezing chamber, the sensor detects continuously the temperature of the ice making tray, and the completion of freeze of water is determined when the temperature of the ice making tray is lower than 0Â° C., a state of a dropping rate of the temperature of the ice making tray is small and continued and then the dropping rate of the temperature is increased, and when an output change of the sensor becomes a predetermined value the water supply is stopped so as to supply a predetermined amount of water.
