Definitions

  • Embodiments of the present invention generally relate to a refrigerator and an ice making method therefor.
  • a refrigerator is an appliance that functions to store food at low temperatures, and may be configured to store food in a frozen state or in a cooled state according to the kinds of food to be stored.
  • the inside of a refrigerator is cooled by cool air continuously supplied to the inside of the refrigerator.
  • the cool air is continuously produced by a heat exchanging operation between air and refrigerant performed in a refrigeration cycle composed of four processes: compression, condensation, expansion, and evaporation that are sequentially performed.
  • Cool air supplied to the inside of the refrigerator is evenly distributed to the interior of the refrigerator due to convection of air, so that the cool air can store food inside the refrigerator maintained at a desired temperature.
  • the body of a refrigerator typically has a rectangular hexahedral shape with a front opening, with a refrigerator compartment and a freezer compartment defined in the refrigerator body.
  • the front of the refrigerator body may be provided with both a refrigerator compartment door and a freezer compartment door that can open or close the refrigerator compartment and the freezer compartment, respectively.
  • the storage space defined inside the refrigerator may be provided with a plurality of drawers, shelves, and boxes designed to store various kinds of food in an optimal state.
  • a top mount type refrigerator in which the freezer compartment is provided in the upper part of the refrigerator body and the refrigerator compartment is in the lower part of the refrigerator body
  • a bottom freezer type refrigerator in which the freezer compartment is in the lower part of the refrigerator body
  • the bottom freezer type refrigerator is advantageous in that the relatively frequently used refrigerator compartment is provided in the upper part of the refrigerator body and the less frequently used freezer compartment is provided in the lower part of the refrigerator body, thereby allowing users to more efficiently use the refrigerator compartment.
  • the bottom freezer type refrigerator in which the freezer compartment is in the lower part is problematic in that to take ice cubes from the freezer compartment, requires a user to open the freezer compartment door and to bend over to take ice cubes.
  • a refrigerator in which an ice dispenser for dispensing ice cubes is provided in a refrigerator compartment door placed in the upper part of a bottom freezer type refrigerator has been proposed and used.
  • an ice making device for making ice cubes may be provided in the refrigerator compartment door or inside the refrigerator compartment.
  • cool air that has been produced by an evaporator, is divided and discharged both into the freezer compartment and into the refrigerator compartment.
  • cool air that was discharged into the freezer compartment flows to the ice making device via a cool air supply duct arranged in a sidewall of the refrigerator body, and then freezes water while circulating inside the ice making device. Thereafter, the cool air is discharged from the ice making device into the refrigerator compartment via a cool air restoration duct arranged in the sidewall of the refrigerator body, so the cool air can reduce the temperature inside the refrigerator compartment.
  • cool air flows to the ice making device via the cool air supply duct and flows from the ice making device via the cool air restoration duct, so cool air supply efficiency of the refrigerator is reduced due to the flowing of cool air via both the cool air supply duct and the cool air restoration duct.
  • the refrigerator may waste an excessive amount of electricity during a continuous operation of the refrigerator.
  • the present invention has been made keeping in mind the above problems occurring in the related art, and the embodiments of the present invention propose a refrigerator and an ice making method therefor in which cool air produced from a cooling duct can be efficiently used to make ice cubes.
  • a refrigerator including: a refrigerator body; a storage space that is defined in the refrigerator body; a door that opens and closes the storage space; an ice making unit disposed on the door and configured to make ice cubes; a cool air producing unit that cools air inside a cooling duct so as to produce cool air; and a cool air circulation unit that supplies the cool air from the cool air producing unit to the ice making unit and discharges air from the ice making unit to the cool air producing unit.
  • Exemplary embodiments of the present invention are advantageous in that the embodiments can make ice cubes using the cool air directly produced from the cooling duct, thereby increasing ice making efficiency and cool air supply efficiency.
  • Another advantage of the exemplary embodiments of the present invention resides in that the cool air circulates only a short distance within an ice making space defined between the cooling duct and the refrigerator compartment door. Accordingly, when compared to conventional techniques in which cool air produced from the lower part of a refrigerator flows to an ice making space defined in a refrigerator compartment door, the present invention can efficiently reduce loss of cool air and can save electricity during operation of the refrigerator.

  • the present invention may be adapted to various types of refrigerators without being limited to the bottom freezer type refrigerator.
  • the construction of the refrigerator body 10, the barrier 20, the refrigerator compartment door 30, and the freezer compartment door 40 remains the same as that of a refrigerator body, a barrier, a refrigerator compartment door, and a freezer compartment door of a conventional refrigerator, and further explanation is thus omitted.

  • the cooling duct 210 is disposed in the refrigerator body 10, and the ice making unit 100 is disposed on the refrigerator compartment door 30 of the refrigerator 1, so when the refrigerator compartment door 30 is closed onto the refrigerator body 10, the first duct hole 212 and the second duct hole 213 of the cooling duct 210 couple with the inlet hole 310 and the outlet hole 320 of the ice making unit 100, respectively.

  • the air discharged from the ice making unit 100 is cooled again inside the cooling duct 210 prior to being introduced into the inlet hole 310 of the ice making unit 100.
