Abstract:
The present invention relates to a damping hinge module for a refrigerator door, which is mounted to a refrigerator door so as to allow the refrigerator door to be opened and closed slowly. The damping hinge module for a refrigerator door according to the present invention comprises: a housing mounted to the refrigerator door and having a first inner chamber and a second inner chamber formed therein, the second inner chamber containing oil; a shaft extending through the first inner chamber and the second inner chamber while one end thereof is disposed in the first inner chamber and the other end thereof is disposed in the second inner chamber; a driving part insertedly disposed in the first inner chamber and mounted to one end of the shaft; and a damping part insertedly disposed in the second inner chamber, wherein: when the housing is partially rotated by an external force, the driving part semi-automatically rotates the housing over the remaining rotation angle; the other end of the shaft and the inner wall of the second inner chamber are spaced apart from each other while the oil is filled in the space interposed therebetween; and when the housing is rotated, the damping part disposed in the second inner chamber produces different damping forces for damping the rotational torque of the housing, depending on the rotation direction of the housing.
