Abstract:
1. A refrigerator including an ice dispenser, comprising: a duct cap that is movable between open and closed positions to open and close an ice duct formed in the refrigerator; a lever that is operably coupled to the duct cap to move the duct cap between the closed and open positions; a joint member that is operably coupled to the duct cap such that the joint member moves as the duct cap moves; a joint member connection bar coupled to the joint member, wherein the joint member is rotatably coupled to an end of the joint member connection bar; a frictional member disposed to come in frictional contact with the joint member as the joint member moves, wherein friction developed between the frictional member and the joint member acts to delay a closing operation of the duct cap; and an elastic member coupled between the joint member connection bar and the joint member, wherein the elastic member biases the joint member in a first rotational direction which causes the joint member to extend away from the end of the joint member connection bar, and wherein when the duct cap is moving from the closed to the open position, contact between the joint member and the frictional member causes the joint member to rotate in a second rotation direction, thereby compressing the elastic member, wherein the refrigerator further comprises: a rotating shaft, wherein the duct cap is attached to the rotating shaft such that rotation of the shaft moves the duct cap between the open and closed positions; and a shaft connection bar that is coupled between the lever and the rotating shaft.
