Ice-crushing device for refrigerators
First Claim
1. An ice-crushing device for refrigerators, comprising:
- a first set of blades rotatable about a first rotary shaft by a driving force, each blade of the first set of blades comprising a guide slit formed in a side thereof;
a second set of blades fitted on a second rotary shaft of a motor for performing a rotating operation; and
an actuating lever having a first end extending in the guide slits, the actuating lever being rotated about a second end of the actuating lever when a driving force of a driving unit is transmitted to the actuating lever, to perform a rectilinear reciprocating movement along the guide slits,wherein the second set of blades applies a torque to the first set of blades when the ice-crushing device performs an ice-crushing operation, andan angle between a first reference line, which is a line passing through a center of the actuating lever, and a second reference line, which is a line passing from the first end of the actuating lever through the center of the first rotary shaft, is an acute angle.

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.
