Ice maker and refrigerator

Abstract

A method controls a refrigerator including first and second trays defining an ice, a driving unit for moving the second tray, an ice bin for storing ice produced in the ice chamber, and an ice-fullness detection means for detecting whether the ice bin is full of ice. The method includes supplying water to the ice chamber when the second tray is at a water-supply position, making ice after the second tray has moved to an ice-making position in an inverse direction after the water supply has been completed, determining whether the ice bin is full of ice after the ice making is completed, moving the second tray to an ice-separating position and then rotating in the inverse direction if it is not determined whether the ice bin is full of ice, and determining again whether the ice bin is full of ice after ice separation is completed.

What is claimed is: 
     
         1 . A method for controlling a refrigerator including a first tray configured to form a portion of an ice chamber, a second tray configured to form another portion of the ice chamber, a driving unit configured to move the second tray, an ice bin configured to store ice generated in the ice chamber, and an ice-fullness detection device configured to detect whether the ice fullness of the ice bin, the method comprising:
 performing water supply to the ice chamber in a state where the second tray is moved to a water supply position;   performing ice making after the second tray is moved from the water supply position to the ice making position in a reverse direction after the water supply is completed;   determining whether the ice fullness of the ice bin after completion of ice making;   rotating the second tray in a reverse direction after the second tray is moved to an ice separation position if the ice fullness is not detected in the determining whether the ice fullness of the ice bin; and   determining again whether the ice fullness of the ice bin after the ice separation is completed.
