Definitions

  • Embodiments of the present disclosure relate to an ice-making device.
  • a refrigerator is an appliance used for storing food or other times at low temperature, e.g., in a frozen state or refrigerated.
  • the interior of the refrigerator is cooled by cold air circulating therein.
  • Cold air can be continuously generated as a refrigerant recycles through compression, condensation, expansion and evaporation.
  • Cold air supplied in the refrigerator is uniformly distributed by convection.
  • a top-mount-type refrigerator has a freezer located on top of a refrigeration compartment.
  • a bottom-freezer-type refrigerator has a freezer located under the refrigeration compartment. This enables a user to conveniently access the refrigeration compartment. On the other hand, this may be inconvenient for a user to access the freezer, if the user has to bend or lower his or her body to reach, e.g., to take out ice pieces.
  • Some bottom-freezer-type refrigerators have an ice dispenser disposed in a refrigeration compartment door located at the upper side of the refrigerator. As the ice-making device is also disposed in the door of the refrigeration compartment, cooling efficiency of the ice-making device typically is unsatisfactory.

  • the air guide 420 may have a substantially L-like shape overall.
  • the fan motor 410 may be coupled to one or both of the first route portion 421 and the second route portion 422 to blow cold air toward the air guide 420.
  • An ice bucket 500 configured to store ice produced in the ice maker 300 may be disposed below the ice maker 300.
  • a sensor (not shown) may be disposed in the ice bucket 500 to determine the amount of ice stored in the ice bucket 500.
  • the ice-making device 2 includes the air guide 420 that can guide and distribute cold air. Cold air having a lowest temperature is preferentially supplied to the ice maker 300, thereby improving the cooling efficiency of the ice-making device 2.
  • cold air introduced into the ice-making room 100 through the intake port 110 may be delivered to the ice bucket 500 disposed under the ice maker 300 through the second route portion 422.
  • the temperature in the ice bucket 500 may be maintained without requiring an additional cooling device or an additional cold air guide.
  • ice in the ice bucket 500 can remain frozen.
