Patent ID: 6857279

Claim:
An ice maker for releasing ice of which lower portion melts by a heater with a driving force of a motor, comprising: a temperature sensor installed to th exterior of an ice-making container for sensing whether the ice has been made within the ice-making container; a first magnet installed to a gear rotated by the driving force of the motor for determining when the heater is turned off; a first hall sensor for sensing a magnetic force generated from the first magnet; a water amount regulating knob formed to protrude outside of the ice maker for regulating the amount of water supplied to the ice-making container; and a microcomputer for turning the heater on and off based on a sensing signal of the first hail sensor when a sensed temperature of the temperature sensor reaches a predetermined value, and regulating the amount of water supplied to the ice-making container based on a regulating signal transmitted from the water amount regulating knob.
