Description
- This application is based on and claims priority from Korean Patent Application No. 10-2015-0085584, filed on Jun. 17, 2015, the disclosure of which is incorporated herein in its entirety by reference.
- The present invention generally relates to a refrigerator and an ice making method thereof.
- A Refrigerator, which is a device intended to store food items at low temperatures, may be configured to refrigerate or freeze food items depending on the types of food to be stored.
- The inside of a refrigerator is cooled by continuously supplied cooling air and cooling air continuously generated through a heat exchanging operation of a refrigerant based on a refrigerating cycle including a process of compression-condensation-expansion-evaporation. The cooling air supplied to the inside of the refrigerator is evenly transferred to the inside of the refrigerator by a convection current to store food items within the refrigerator maintained at a desired temperature.
- In general, a refrigerator body has a rectangular shape with an open front side, and a refrigerating chamber and a freezing chamber may be provided in the refrigerator body. Further, a refrigerating chamber door and a freezing chamber door may be installed on the front side of the body to selectively close the openings. In addition, a plurality of drawers, shelves, receiving boxes, and the like may be provided in a storage space within the refrigerator to keep various food items in an optimal state.
- Conventionally, top mount type refrigerators (in which a freezing chamber is positioned above and a refrigerating chamber is positioned below) are popular in the mainstream, but recently, bottom freeze type refrigerators (in which a freezing chamber is positioned in a lower portion to enhance user convenience) have also been released. Here, the bottom freeze type refrigerator in which the frequently used refrigerating chamber is positioned above and the less frequently used freezing chamber is positioned below is advantageous in that users may easily access the refrigerating chamber. For the bottom freeze type refrigerator, however, since the freezing chamber is positioned below, in order for a user to take ice, the user bends himself or herself over to open the freezing chamber door to take ice.
- In order to solve such a problem, recently, bottom freeze type refrigerators (in which a dispenser for dispensing ice is provided in a refrigerating chamber door positioned in an upper portion thereof) have been released. In this case, an ice making device for generating ice may be provided in the refrigerating chamber door or in the interior of the refrigerating chamber.
- For example, in the bottom freeze type refrigerator in which the ice making device installed in the refrigerating chamber door, air (cooling air) cooled by an evaporator is dividedly discharged to the freezing chamber and the refrigerating chamber. The cooling air discharged to the freezing chamber 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. Thereafter, the cooling air within the ice making device is discharged to the refrigerating chamber through a cooling air reducing duct embedded in the sidewall of the main body of the refrigerator, lowering an internal temperature of the refrigerating chamber.
- However, since the cooling air of the freezing chamber side is used in the ice making device both through the cooling air supply duct and also the cooling air reducing duct, then the cooling air is moving in the cooling air supply duct and the cooling air reducing duct. Due to this, the supply efficiency of the cooling air may he degraded.
- In addition, since the cooling air of the freezing chamber side should be moved to the ice making device of the refrigerating chamber door, when the refrigerator is continuously operated, power consumption may increase significantly due to the operation of the refrigerator.
- In view of the above, therefore, embodiments of the present invention provide a refrigerator in which cooling air cooled in a cooling air duct can be directly used to generate ice, and an ice making method thereof.
- In one embodiment, the present invention is implemented as a refrigerator including a main body and a storage space installed within the main body. The refrigerator further includes a door configured to open and close the storage space and an ice making chamber provided in the door. The refrigerator further includes a cooling duct configured to allow cooling air to flow in a longitudinal direction, and disposed in the main body with both ends connected to the ice making chamber. The cooling air circulates to the ice making chamber. The refrigerator further includes an evaporation coil disposed in the cooling duct and configured to cool air to generate cooling air through heat exchanging with a refrigerant.
- In another embodiment, the present invention is implemented as an ice making method of a refrigerator. The method includes supplying a refrigerant, to an evaporation coil and supplying air to a cooling duct with the evaporation coil wound therearound. The method further includes cooling the air to produce cooling air through heat exchange between the air and the refrigerant and supplying the cooling air to an ice making chamber for producing ice. The method further includes discharging the cooling air within the ice making chamber to the cooling duct and recooling the discharged cooling air in the cooling duct.

FIGS. 1 to 4 , the refrigerator in accordance with an embodiment of the present invention may include amain body 10 that forms an appearance, abarrier 20 that demarcates a storage space of themain body 10, a door for opening and closing the storage space, anice making chamber 110 provided in the door, and anice making duct 200 for providing cooling air to theice making chamber 110. - Here, the refrigerator may include a refrigerating
chamber door 30 for selectively closing the refrigerating chamber on both edges of a front surface of themain body 10, and afreezing chamber door 40 for closing a front opening of the freezing chamber. The storage space may include the refrigerating chamber and the freezing chamber demarcated by thebarrier 20. - The
refrigerator 1 in accordance with this embodiment is a bottom freezer type refrigerator in which the freezing chamber is positioned in a lower portion thereof, but the present invention is not limited thereto and may be applied to various types of refrigerators, in addition, the configuration of themain body 10, thebarrier 20, the refrigeratingchamber door 30, and thefreezing chamber door 40 corresponds to the configuration of a main body, a barrier, a refrigerating chamber door, and a freezing chamber door applied to general refrigerators, and thus, a detailed description thereof will be omitted. - The
ice making duct 200 may include acooling duct 210 in which cooling air is movable in a longitudinal direction therein, and anevaporation coil 220 for cooling thecooling duct 210 through conduction. - Specifically, the
cooling duct 210 may include acooling channel 211, afirst duct hole 212, and asecond duct hole 213. - The
cooling channel 211, which is a passage in which cooling air moves, may extend in a longitudinal direction within thecooling duct 210. In particular, thecooling channel 211 has a length sufficient for cooling of air with cooling air, and thus, the air, while moving in thecooling channel 211 for a predetermined period of time, may be cooled to cooling air having a temperature (e.g., 14 degrees or lower below zero) allowing for ice making. - Further, the
first duct hole 212 may be provided at one end of thecooling channel 211 to supply the cooling air to theice making chamber 110, and thesecond duct hole 213 may be provided at the other end of thecooling channel 211 to receive the cooling air from theice making chamber 110. For example, thefirst duct hole 212 may be connected to an upper portion of theice making chamber 110, thesecond duct hole 213 may be connected to a lower portion of theice making chamber 110, and the cooling air within thecooling duct 210 may move from a lower end of thecooling duct 210 to an upper end thereof. - The
cooling duct 210 may extend to be bent in a vertical direction of themain body 10 such that thecooling duct 210 is sloped in a forward direction of themain body 10 within themain body 10. For example, thecooling duct 210 may be bent to have a “” shape or a “C” shape in a forward direction of themain body 10. - In this manner, since the
cooling duct 210 is bent to have a “” shape or a “C” shape, when defrosted water is generated within thecooling duct 210, the defrosted water may move to the lowermost portion of thecooling duct 210 and may be subsequently discharged to the outside through a separate drain device (not shown). - The
cooling duct 210 is installed in themain body 10 of therefrigerator 1, and theice making chamber 110 is provided within the refrigeratingchamber door 30 of therefrigerator 1. Here, thefirst duct hole 212 and thesecond duct hole 213 of thecooling duct 210 may be selectively connected to aninlet 310 and anoutlet 320 of theice making chamber 110, respectively, depending on opening and closing of the refrigeratingchamber door 30. - That is, when the
refrigerator door 30 is closed to themain body 10, cooling air within thecooling duct 210 may be introduced to theinlet 310 of theice making chamber 110 through thefirst duct hole 212, and the cooling air introduced to theice making chamber 110 may circulate within theice making chamber 110 to freeze water within theice making chamber 110 to make ice. Thereafter, the cooling air within theice making chamber 110 may be discharged to thesecond duct hole 213 of the coolingduct 210 through theoutlet 320, and the cooling air discharged from theice making chamber 110 may he recooled in the coolingduct 210 and then introduced again to theinlet 310 of theice making chamber 110. - The
evaporation coil 220 may cool air within the coolingduct 210 to generate cooling air through heat exchanging with a refrigerant. To this end, theevaporation coil 220 is installed to be wound around the coolingduct 210, and thus, when the refrigerant circulates depending on the refrigerating cycle, theevaporation coil 220 may cool the coolingduct 210 through conduction. - The
evaporation coil 220 may serve as an evaporator of the refrigerating cycle. For example, theevaporation coil 220 may implement the refrigerating cycle including a process of compression-condensation-expansion-evaporation, together with acompressor 11, acondenser 12, and anexpansion valve 13. - In this embodiment, the configuration of the
compressor 11, thecondenser 12, theexpansion valve 13, and theevaporation coil 220 is provided as a refrigerating cycle for providing cooling air to theice making chamber 110, but the configuration may also provide the cooling air to the refrigerating chamber and the freezing chamber of the refrigerator, as well as to theice making chamber 110. In addition, the configuration of thecompressor 11, thecondenser 12, and theexpansion valve 13 may also share a refrigerant with an evaporator (not shown) for providing cooling air to the refrigerating chamber and the freezing chamber. -
FIG. 5 is a state view illustrating an exemplary connection between the ice making chamber and the cooling duct in the refrigerator in accordance with an embodiment of the present invention, andFIG. 6 is a view illustrating an internal configuration of the ice making chamber of the refrigerator in accordance with an embodiment of the present invention. - As illustrated in
FIGS. 5 and 6 , theice making chamber 110 may be provided in the refrigeratingchamber door 30 of therefrigerator 1. In this embodiment, a case in which theice making chamber 110 is provided in an upper portion of the refrigeratingchamber door 30 is presented as an example, but this is merely illustrative and theice making chamber 110 may be installed in other position of the refrigeratingchamber door 30. - The
ice making chamber 110 may provide anice making space 111 in which ice is generated. In addition, anice maker 120, anice bank 130, and acirculation fan 330 may be provided within theice making chamber 110. - The
ice maker 120 may cool water to ice using cooling air introduced to the ice making space ill and dispense the cooled ice to theice bank 130. Theice bank 130 may be positioned below theice maker 120 from which ice is dispensed, and theice bank 130 may store the dispensed ice and provide the ice to a user through a dispenser unit (not shown). Thecirculation fan 330 may move the cooling air from theinlet 310 to theoutlet 320. -
FIG. 7 is a flowchart illustrating an ice making method using an ice making duct of a refrigerator in accordance with an embodiment of the present invention. - As illustrated in
FIG. 7 , the ice making method of the refrigerator in accordance with an embodiment of the present invention may include the steps of supplying a refrigerant to an evaporation coil (step S100), supplying air to a cooling duct with the evaporation coil wound therearound (step S200), cooling the air to cooling air through heat exchanging between the air and the refrigerant (step S300), supplying the cooling air to an ice making chamber for generating ice (step S400), discharging the cooling air within the ice making chamber to the cooling duct (step S500), and recooling the discharged cooling air in the cooling duct (step S600). - In step S100 of supplying a refrigerant to the evaporation coil, a refrigerant of a refrigerating cycle may be supplied to the evaporation coil. Here, the evaporation coil may form a refrigerating cycle including a process of compression-condensation-expansion-evaporation, together with a compressor, a condenser, and an expansion valve.
- In step S200 of supplying air to the cooling duct with the evaporation coil wound therearound, air may be supplied to the cooling duct to cool the air. The air supplied to the interior of the cooling duct may move from a lower end to an upper end of the cooling duct.
- In step S300 air is cooled to produce cooling air through heat exchange between the air and the refrigerant, air is moved within the cooling duct around which an evaporation coil is wound so as to be cooled to cooling air. Here, air within the cooling duct may move along a cooling channel, while being exchanged with the refrigerant of the evaporation coil for a predetermined period of time, and thus, the air discharged from the cooling duct may be cooled to cooling air having a temperature (e.g., 14 degrees or lower below zero) allowing for ice production.
- In step S400 of supplying cooling air to the ice making chamber to generate ice, the cooling air cooled in the cooling duct may be supplied to an ice making space of the ice making chamber through an inlet of the ice making chamber. The cooling air introduced to the ice making space may circulate in the ice making space through an operation of a circulation fan, freezing water within the ice making space to produce ice.
