  • Patent number: 8555658
    Abstract: An ice maker, a refrigerator including the ice maker, and an ice making method are provided. The ice maker includes a tray having a predetermined length and to which water is supplied to make ice. The ice maker is configured to mechanically separate the ice from the tray by using pistons which are driven by being pressed by structures. This allows the ice maker to have a reduced size, and a small occupation area, thereby implementing a slim configuration of a refrigerator. Furthermore, since an installation height of the ice maker is lowered, a path for supplying cool air may be shortened. This may prevent loss of cool air being supplied to the ice making chamber. Since the ice maker has a simplified configuration and precise operation controls, the fabrication costs may be reduced, and inferiority of the ice maker due to malfunctions may be prevented.

  • Patent number: 8459055
    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.
