  • Patent number: 7481387
    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.

  • Publication number: 20080295538
    Abstract: Disclosed is the auger in an ice bin mounted in a refrigerator, and the like. The auger in the ice bin is configured to rotate a plurality of augers having spiral-shaped transfer blades and to dispose ice in each space between the transfer blades of the auger for transfer. Accordingly, a certain amount of ice can always be discharged without simultaneously discharging a great amount of ice, and a user may select the number of ice, thus to diversity functions of an ice dispenser. In addition, since the auger is made of a flexible material, the ice can be prevented from being crushed during transfer, thereby enhancing the reliability of the ice dispenser.

  • Patent number: 7458230
    Abstract: A refrigerator is provided with an airflow passage for an ice making compartment of the refrigerator. In the refrigerator, a main body has an opened side, and a door selectively closes the opened side of the main body. An ice making compartment is formed in the door, the ice making compartment being insulated from the outside and being kept at a low temperature. A duct is formed in the main body for exchanging cooling air with the ice making compartment, and a cooling air passage is formed at an outer surface of the ice making compartment to connect the duct with the ice making compartment. A switching unit closes the cooling air passage when the door is opened, and opens the cooling air passage when the door is closed. With this arrangement, the cooling air can be sufficiently supplied to the ice making compartment without the penetration of foreign substance.

  • Publication number: 20080174219
    Abstract: There is provided a refrigerator. The refrigerator includes a storage space receiving food, a door, and a dispensing apparatus. The door selectively opens and closes the storage space. The dispensing apparatus dispenses contents stored in the storage space without opening the door. The dispensing apparatus substantially protrudes from an outer surface of the door. According to the refrigerator, since the internal structure of the door is simplified, fabrication of the refrigerator becomes easy. In addition, the internal space of the refrigerator is enlarged and a user can use a container of various sizes and shapes. Furthermore, the thickness of the door is prevented from becoming thin, thereby reducing a heat loss in the refrigerator.
