  • Publication number: 20080156023
    Abstract: Provided is an ice dispensing apparatus. The ice dispenser discharges a predetermined number of ice pieces at a time, and thus malfunctioning or errors caused by bottleneck condition can be prevented. Furthermore, inside a case of the ice dispenser, pieces of ice can be effectively prevented from sticking to each other in a simple way, and thus the reliability of products can be increased. The ice dispensing apparatus includes a case, a driving unit, and a regulator. The case includes an inlet receiving ice and an outlet discharging ice. The driving unit is disposed inside or outside the case. The regulator is disposed in the case at a predetermined side and rotatable by the driving unit.

  • Patent number: 7383689
    Abstract: Disclosed is a dispenser of an icemaker in a refrigerator for maximizing an inner space when a total size is the same, and for minimizing the total size when the inner space is the same. The dispenser of the icemaker in the refrigerator includes an ice chute being a passage through which the ice produced from the icemaker is discharged; and a container supporter provided at an outer case and disposed to be perpendicular to an outer surface of the outer case when the ice is discharged outside through the ice chute, the contain supporter allowing a container seated thereon to receive the ice discharged from the ice chute. The ice chute is closed and not exposed outside when the ice-discharging process is finished, and the container supporter is not exposed to the outer surface of the outer case.

  • Patent number: 7272949
    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.

  • Patent number: 7240511
    Abstract: A cold air path structure of a refrigerator is provided. The cold air path structure defines a passage from an ice machine installed in a freezing chamber to a chilling chamber in order to discharge an cold air used to freeze water of the ice machine to the chilling chamber, such that new cold air can be smoothly supplied to the ice machine, thereby increasing the efficiency of the ice machine. Further, an additional air passage is not required to supply the cold air to the chilling chamber, thereby simplifying the structure of the refrigerator and decreasing power consumption.
