Abstract
Disclosed herein is an ice-crushing device for refrigerators that is capable of crushing ice by torque of rotary blades relative to stationary blades wherein the stationary blades are selectively operated according to selected ice mode, i.e., crushed ice mode or ice cube mode, to allow the stationary blades to have a damper function, thereby preventing stoppage of crushed ice, and therefore, eliminating a locking phenomenon, which is caused by the stoppage of crushed ice. The ice-crushing device comprises an actuating unit for rotating the stationary blades clockwise or counterclockwise about a rotary shaft when a driving force is transmitted to the actuating unit, and a driving unit for supplying the driving force to the actuating unit.
