  • [0054]
    The ice cube dispensing unit 50 further comprises an ice cube crusher 70 equipped to the second end 22 of the ice cube container 20 to dispense crushed ice together with the ice cubes. The ice cube crusher 70 comprises a pair of rotational cutters 56 coupled with the rotational shaft 53 at a location corresponding to the ice cube/crushed ice outlet 59, and a stationary cutter 69 fixed at the ice cube/crushed ice outlet 59 to be perpendicular to the rotational cutters 56, in order to crush the ice cubes, having been conveyed to the ice cube/crushed ice outlet 59 by the spiral wings 55, into the crushed ice.
  • [0055]
    The ice cube dispensing unit 50 further comprises an outlet adjusting device 60, which can adjust the size of the ice cube/crushed ice outlet 59 such that the ice cubes and the crushed ice can be selectively dispensed from the ice cube dispensing unit 50.
  • [0056]
    Accordingly, after adjusting the size of the ice cube/crushed ice outlet 59 to prevent the ice cubes from escaping through the outlet 59 by use of the outlet adjusting device 60 through the control unit 8, the driving motor 61 is driven to rotate the spiral guide 52, the rotational shaft 53, and the spiral wings 55 coupled with the rotational shaft 53. Thereby, the ice cubes contained in the ice cube container 20 are pushed into the guide barrel 54, in which the ice cubes are conveyed to the ice cube/crushed ice outlet 59 of the case 58 by the spiral wings 55. As a result, the ice cubes are crushed into crushed ice of a size corresponding to the adjusted size of the ice cube/crushed ice outlet 59 through operation of the rotational cutters 56 and the stationary cutter 57. The crushed ice is discharged to the outside of the freezing compartment door 2 through ice cube/crushed ice discharge port 14 of the dispensing passage 17 formed in the freezing compartment door 2.
  • [0057]
    On the contrary, when the driving motor 61 is driven with the size of the ice cube/crushed ice outlet 59 adjusted to allow the ice cubes to pass through the outlet 59 by use of the outlet adjusting device 60 through the control unit 8, the ice cubes are conveyed to the ice cube/crushed ice outlet 59 by the spiral wings 55, and pass through the outlet 59 without being crushed by the rotational cutters 56 and the stationary cutter 57. Then, as shown in FIG. 6, the ice cubes are discharged to the outside of the freezing compartment door 2 through ice cube/crushed ice discharge port 14.
  • [0058]
    As is apparent from the above description, the refrigerator according to an embodiment of the invention includes the shaved ice dispensing unit, and the ice cube dispensing unit positioned within the ice cube container to allow ice cubes, crushed ice, and shaved ice to be smoothly dispensed to the outside of the freezing compartment door according to selection of a user, so that the user of the refrigerator is provided with various shapes of ice.
  • [0059]
    Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that various modifications, additions and substitutions may be made in these embodiments without departing from the principle and spirit of the invention, the scope of which defined in the claims and their equivalents.
