  • Patent number: 8683822
    Abstract: A refrigerator includes a freezing chamber door provided with an ice-making assembly. Ice made by the ice-making assembly can be immediately drawn out to the outside by opening an exclusively used home-bar door. In addition, an ice-making case is coupled by a coupling formed integrally with the freezing chamber door and the ice-making case without a coupling tool or operation. Moreover, if a water bucket is installed to the ice-making case, a water supply hole of the lower end of the water bucket is opened by an opening and closing structure, so that water in the water bucket is automatically supplied to an ice tray. In addition, an ice-separating lever having a ? shape is provided to simultaneously rotate a plurality of ice trays. Meanwhile, an ice bank cooperates with the home-bar door to be drawn out forward as the home-bar door is opened.

  • Patent number: 8104304
    Abstract: The present invention relates to an ice-making device for a refrigerator. The ice-making device of the present invention comprises a water tank detachably installed to a rear surface of a refrigerator door for selectively opening or closing a storage space, first and second ice trays rotatably installed to the rear surface of the door to make ice using water supplied from the water tank, and an ice bank installed to the rear surface of the door to store therein the ice made in the first and second ice trays. According to the present invention, ice can be more simply and easily taken out while minimizing the leakage of cold air circulating in the storage space. Further, ice can be stored in a more sanitary way while minimizing the contamination of the storage space in the process of making ice.
