AUTOMATIC ICEMAKER FOR REFRIGERATOR

PURPOSE:To correct unevennesses of performance of a feed water pump and an applied voltage and to always manufacture uniform ice by so forming as to alter a water supply amount from a feed water pump by an input voltage input to a microcomputer via an actuator. CONSTITUTION:Water of a feed water tank 6 installed in a cold storage chamber is supplied from a feed water tray 12 to an icemaking tray 9 in a freezing chamber 3 by a feed water pump 11, and ice is made with cold gas fed by a cold gas supply fan 16. The thus made ice is separated by an icemaking unit 1, and stocked in an ice storage box 4. An actuator 5 mounted at a lower part of a freezing chamber door 2 of such an icemaker is operated to vary an operating time of the pump 11. That is, the actuator 5 is formed of a variable resistor, and a voltage is varied to 0-5V by its operation. This voltage is read by a microcomputer, a time of operating the pump 11 is decided, and ON/OFF time of a transistor is controlled.
