Abstract:
An apparatus for controlling of a refrigerator automatic ice machine having an ice transfer motor, a motor driver for driving the ice transfer motor and an ice-fullness lever connected with one end of a rotation shaft of the ice transfer motor, for sensing ice-fullness of an ice box, comprising:a first detection plate installed on another end of the rotation shaft of the ice transfer motor, for detecting an initial position of an ice tray, the ice-fullness of the ice box and rotation angles of the ice transfer motor;a second detection plate installed on one end of the ice-fullness lever, for detecting the ice-fullness of the ice box;a first pulse generator for generating pulse trains by the combination of movements of said first and second detection plates according to the driving of the ice transfer motor; anda controller for generating a forward or a reverse rotation control signal according to the pulse trains provided from said first pulse generator and providing the forward or the reverse rotation control signal to the motor driver.
