APPARATUS FOR CONTROLLING HEATER OF ICE MAKING MACHINE FOR REFRIGERATOR

摘要

PURPOSE: An apparatus for controlling a heater of an ice making machine for a refrigerator is provided to minimize influence of surrounding environment. CONSTITUTION: An apparatus includes a plate(52) having at least one groove(62,63) formed at regular intervals and installed on a rotary axis(54) of a motor(56) to rotate together with an ice ejecting lever(14); an optical sensor detecting turning amount of the ice ejecting lever through the grooves formed on the plate; and a control part(58) turning off a heater generating heat to eject manufactured ice from an ice making bin when the optical sensor detects signal twice through the grooves formed on the plate.
