Definitions

  • the present invention relates to refrigerators, and particularly relates to a refrigerator with an ice dispenser for supplying ice.
  • the ice dispenser includes a supply pipe which is a supply path for ice.
  • the ice dispenser supplies the user with the ice made by the ice maker through the path in the supply pipe.
  • the cup which the user uses for keeping the ice generally has a circular opening at the top.
  • the cross-sectional shape of the supply pipe in the ice dispenser is circular, corresponding to the shape of the opening of the cup.
  • the cross-sectional shape of the supply pipe in the conventional ice dispenser is circular, sometimes the ice falls down the supply pipe in spiral.
  • the ice moves toward the centrifugal direction by the centrifugal force, falling off of the side of the cup.
  • the present invention has been conceived in response to the problem, and it is an object of the present invention to provide a refrigerator having an ice dispenser capable of preventing the ice from falling off of the side of the cup when the user puts the ice into the cup.
  • the refrigerator according to the present invention is a refrigerator including an ice dispenser for supplying ice, in which the ice dispenser includes: a serving opening for serving the ice to outside of the ice dispenser; and a guide having a flat surface for guiding the ice to the serving opening.
  • the supplied ice slips along the flat surface of the guide. Accordingly, when the ice is served from the serving opening, the ice does not fall out of the cup by centrifugal force and others. Accordingly, when the user puts the ice into the cup, it is possible to prevent the ice from falling off of the side of the cup.
  • the serving opening is a circular opening.
  • the serving opening for serving the ice is the circular opening. Since the serving opening is circular corresponding to the shape of the opening of the cup, it is possible to prevent the ice from falling off of the cup when the user puts the ice into the cup.
  • the ice dispenser further includes a baffle provided downward above the guide at a predetermined distance from the guide.
  • the baffle is arranged at the top portion of the supply pipe. Accordingly, even if the user inserts his hand inside the supply pipe for example, it is possible to prevent the hand from touching devices above the supply pipe.
  • the ice dispenser further includes: a serving unit composed of a light-transmissive material and forming the serving opening; and a lighting apparatus for lighting up the serving opening through the serving unit.
  • the lighting apparatus such as LED is arranged, lighting up the serving opening. This helps the user to check the serving opening which is an outlet of the ice, preventing the ice from falling off of the cup when the user puts the ice into the cup.
  • the ice dispenser further includes a reflective member for covering the serving unit at a predetermined distance from the serving unit, and for reflecting light emitted by the lighting apparatus toward the serving unit.
  • the light emitted from the lighting apparatus such as LED is reflected on the reflective member, thereby the reflected light lighting up the serving opening. Accordingly, the light on the serving opening is brighter than the light when the lighting apparatus directly lights up the serving opening. This makes it easier for the user to check the serving opening which is the outlet of the ice more easily, preventing the ice from falling off of the side of the cup when the user puts the ice into the cup.
  • the present invention can not only be implemented as a refrigerator with the ice dispenser, but also as an ice dispenser.
  • the present invention provides a refrigerator including an ice dispenser capable of preventing the ice from falling off of a side of a cup when the user put the ice into the cup. Therefore, the present invention is very highly practical.
