  • Publication number: 20110146331
    Abstract: A refrigerator is provided. The refrigerator includes a cabinet, a refrigerator compartment door, a freezer compartment door, an ice compartment, a dispenser, a cabinet duct disposed in an inner wall of the refrigerator compartment. The cabinet duct allows cool air for making ice to flow therein, and has a cabinet duct opening that opens toward an inside of the refrigerator compartment and that is disposed longitudinally in a vertical direction. The refrigerator also includes an ice compartment duct having an ice compartment duct opening that is configured to communicate with the cabinet duct when the refrigerator compartment door is oriented in a closed position and that is defined longitudinally in a vertical direction. The ice compartment duct is disposed in a sidewall of the ice compartment.

  • Publication number: 20100236270
    Abstract: A dispenser for refrigerator is disclosed. The dispenser for refrigerator includes a pushing member formed in a planar shape and configured to be movable in back and forth direction; a switch configured to be operated by a pushing force applied to be parallel with the pushing member; and a motion conversion unit cooperating with the motion of the pushing member so as for the switch to be pushed. The motion conversion unit includes an oblique member configured to be protruded with being oblique from one side of a rear surface of the pushing member; and a transfer member coming in contact with the oblique member and the switch and having one side fixed to be rotatable in parallel with the pushing member. According to the dispenser for refrigerator, since the motion conversion unit is provided so as to operate the switch resulting from that the transfer member is rotated in parallel with the rear surface of the dispenser housing, it is capable of decreasing an installation space for the dispenser.
