Definitions
- the present invention relates to an ice making duct for a refrigerator and an ice making method using the same.
- a refrigerator is an appliance that serves to store food at low temperatures; it may be configured to store food at temperatures below freezing or at low but above freezing temperatures.
- the temperature inside the refrigerator is maintained at the desired level by cool air that is continuously supplied to the refrigerator.
- the cool air is continuously produced by a heat exchange operation between air and a refrigerant performed in a refrigeration cycle comprising four sequential phases: compression, condensation, expansion, and evaporation. Cool air is channeled to the inside of the refrigerator and is evenly distributed inside the refrigerator by convection.
- the body of a refrigerator typically has a rectangular hexahedral shape that opens frontward, with a refrigerator compartment and a freezer compartment defined and isolated from one another within the refrigerator body.
- the open front of the refrigerator body may comprise 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 comprise a plurality of drawers, shelves, and boxes designed to store various kinds of food in various optimal states.
- 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 provided in the lower part of the refrigerator body is well known.
- a bottom freezer type refrigerator in which the freezer compartment is provided in the lower part of the refrigerator body has been proposed and used.
- the bottom freezer type refrigerator may be preferable since the more frequently used refrigerator compartment is located in the upper part of the refrigerator body and the less frequently used freezer compartment is located in the lower part of the refrigerator body.
- the bottom freezer type refrigerator is problematic in that to take ice cubes from the freezer compartment, a user must open the freezer compartment door and collect ice cubes while bending.
- 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.
- cooling air cooled by an evaporator is separately discharged to the freezing compartment and the refrigerating compartment.
- the cooling air discharged to the freezing compartment side flows to the ice making device along a cooling air supply duct embedded in a sidewall of a main body of the refrigerator and subsequently freezes water, while flowing within the ice making device.
- the cooling air within the ice making device is discharged to the refrigerating compartment through a cooling air reducing duct embedded in the sidewall of the main body of the refrigerator, lowering an internal temperature of the refrigerating compartment.
- the cooling air of the freezing compartment is channeled to the ice making device via the cooling air supply duct and the cooling air reducing duct, the supply efficiency of the cooling air may be suboptimal.
- embodiments of the present invention provide an ice making duct for a refrigerator in which air cooled in a cooling air duct can be directly used to generate ice.
- an ice making duct 200 of the refrigerator in accordance with an embodiment of the present invention may generate ice using air cooled in a cooling duct 210.

- first duct hole 212 may be provided at one end of the cooling channel 211 to supply the cooling air to the ice making compartment 110
- second duct hole 213 may be provided at the other end of the cooling channel 211 to receive the cooling air from the ice making compartment 110.
- first duct hole 212 may be connected to an upper portion of the ice making compartment 110 and the second duct hole 213 to a lower portion of the ice making compartment 110, and the cooling air within the cooling duct 210 may move from a lower end of the cooling duct 210 to an upper end thereof.
- the cooling duct 210 may extend to be bent in a vertical direction of the main body 10 such that the cooling duct 210 is sloped in a forward direction of the main body 10 within the main body 10.
- the cooling duct 210 may be bent to have a "C" shape in a forward direction of the main body 10.
- the cooling duct 210 is bent to have a "C" shape, when defrosted water is generated within the cooling duct 210, the defrosted water may move to the lowermost portion of the cooling duct 210 and may be subsequently discharged to the outside through a separate draining device (not shown).
- the cooling duct 210 is installed in the main body 10 of the refrigerator 1, and the ice making compartment 110 is provided within the refrigerating compartment door 30 of the refrigerator 1.
- the first duct hole 212 and the second duct hole 213 of the cooling duct 210 may be selectively connected to an inlet 310 and an outlet 320 of the ice making compartment 110, respectively, depending on the open or closed state of the refrigerating compartment door 30.
- cooling air within the cooling duct 210 may be introduced to the inlet 310 of the ice making compartment 110 through the first duct hole 212, and the cooling air introduced to the ice making compartment 110 may circulate within the ice making compartment 110 to freeze water within the ice making compartment 110 to make ice. Thereafter, the cooling air within the ice making compartment 110 may be discharged to the second duct hole 213 of the cooling duct 210 through the outlet 320, and the cooling air discharged from the ice making compartment 110 may be re-cooled in the cooling duct 210 and then introduced again to the inlet 310 of the ice making compartment 110.
- the evaporation coil 220 may cool air within the cooling duct 210 by heat exchange with a refrigerant.
- the evaporation coil 220 is installed to be wound around the cooling duct 210, and thus, when the refrigerant circulates, depending on the refrigerating cycle, the evaporation coil 220 may cool the cooling duct 210 through conduction.
- the evaporation coil 220 may serve as an evaporator of the refrigerating cycle.
- the evaporation coil 220 may implement the refrigerating cycle including a process of compression-condensation-expansion-evaporation, together with a compressor 11, a condenser 12, and an expansion valve 13.
- the configuration of the compressor 11, the condenser 12, the expansion valve 13, and the evaporation coil 220 are provided as a refrigerating cycle for providing cooling air to the ice making compartment 110, but the configuration may also provide the cooling air to the refrigerating compartment and the freezing compartment of the refrigerator as well.
- the configuration of the compressor 11, the condenser 12, and the expansion valve 13 may also share a refrigerant with an evaporator (not shown) for providing cooling air to the refrigerating compartment and the freezing compartment.
- the heat transfer fins may be formed of a plurality of radiating fins that protrude inside the cooling duct 210.
- the plurality of radiating fins may be arranged to be spaced apart at predetermined intervals within the cooling duct 210.
- the heat transfer fins serve to increase an area in which heat is exchanged between air moving in the cooling channel 211 within the cooling duct 210 and a refrigerant moving in the evaporation coil 220, thereby effectively transferring cold and heat from the refrigerant to the air.
