Abstract

A refrigerator is provided. The refrigerator may include a body having a storage room, an ice making chamber formed separately from the storage room, and a thermoelectric-module provided in the ice making chamber to generate cold air. The thermoelectric-module does not require a cold air duct to cool the ice making chamber. As a result, space utilization is improved and a capacity of the refrigerator is improved. In addition, energy efficiency may be enhanced because a heater is not required to remove the frost from a cold air duct.

• In reference toFIGS. 1 to 3, an exemplary refrigerator as embodied and broadly described herein may include abody12 that defines an exterior appearance of therefrigerator10. A storage room may be formed in thebody12 to receive food items. The storage room may include a refrigerator compartment (not shown) and a freezer compartment (not shown) that are partitioned by a barrier (not shown) and a partition wall (not shown). In certain embodiments, the refrigerator compartment may be provided in an upper portion of thebody12 and the freezer compartment may be provided in a lower portion of thebody12, as shown inFIG. 1. Other arrangements may also be appropriate.
• The refrigerator may also include a compressor that compresses a low temperature/pressure gaseous refrigerant to output a high temperature/pressure gaseous refrigerant, a condenser that cools and condenses the high temperature/pressure refrigerant transmitted by the compressor, using external air, a valve that controls the flow of cold air having passed through the condenser, a capillary tube that decompresses and discharges the high pressure liquid refrigerant having sequentially passed through the condenser and the valve, and an evaporator that evaporates the refrigerant drawn from the capillary tube at a low pressure into a low temperature refrigerant to absorb the generated heat.
• One ormore doors14 may be coupled to thebody12. In certain embodiments, thedoors14 may include first andsecond doors16 and18 that selectively open and close separate sides of the refrigerator compartment, and athird door22 that selectively opens and closes the freezer compartment, as shown, for example, inFIG. 1. Simply for ease of discussion, the first, second andthird doors16,18 and22 may be referred to collectively as thedoor14. It is well understood that the features to be described may be applied to any one of the first, second orthird doors16,18 and22.
• Aninner space16′ may be formed in thefirst door16. Theinner space16′ may have an opening that faces the inside of the refrigerator compartment. Theinner space16′ may be selectively opened and closed with respect to the inside of the refrigerator compartment by apanel40 which will be described later. Anice maker50, which will be described later, may be installed in theinner space16′ such that theinner space16′ forms an ice making chamber. That is, theinner space16′ and the ice making chamber may refer to substantially the same space, for ease of discussion. In alternative embodiments, theinner space16′ may be formed in thesecond door18 or thethird door22, based on the particular arrangement of the compartments. By extension, theinner space16′ may be formed in various positions within therefrigerator10 as long as an independent ice making chamber is able to be formed.
• The first andsecond door16 and18 may rotatably open and close the refrigerator compartment, without any interference. Specifically, predetermined sides of the first andsecond doors16 and18 may be coupled to hingeparts20 provided at edges of a front of thebody12, such that the first andsecond doors16 and18 may rotate about thehinge parts20. In the embodiment shown inFIG. 1, thethird door22 may slide forward and rearward along a slide rail to open and close the freezer compartment. Ahandle24 may be provided at each of the first, second andthird doors16,18 and22 to provide a grasping surface. Adispenser26 may be provided in one of thedoors14, and in particular, at one of the first, second orthird doors16,18 and22. Thedispenser26 allows ice, beverages or other items which are stored inside thedoor14 to be dispensed outside thedoor14. For ease of discussion, thedispenser26 shown in this embodiment is provided at thesecond door18 so as to not interfere with theinner space16′ of thefirst door16.
• As shown inFIG. 2, thepanel40 may be provided at an interior side of thefirst door16, and may be plate-shaped, corresponding to the shape of theinner space16′ so as to cover the opening into theinner space16′. A first side of thepanel40 may be rotatably coupled to thefirst door16 and a second, opposite side of thepanel40 may rotate about the first side so as to selectively open and close theinner space16′ of thefirst door16. Thepanel40 may partition off theinner space16′ from the refrigerator compartment. Thus, in certain embodiments, thepanel40 may be made of material having good heat-insulation properties.
• Anopening42 may be formed in thepanel40 to provide for the installation of a thermoelectric-module44 and theice maker50. The thermoelectric-module44 may be provided at theopening42. The thermoelectric-module44 may be plate-shaped, corresponding to the appearance of theopening42. Specifically, at least one thermoelectric-module44 may be provided at theopening42, with a first surface of the thermoelectric-module44 positioned facing theinner space16′ and a second, opposite surface of the thermoelectric-module44 positioned facing the inside of the refrigerator compartment. Aheat absorption part44aof the thermoelectric-module44 may be positioned facing theinner space16′ so as to absorb heat, and aheat radiation part44bof the thermoelectric-module44 may be positioned facing the refrigerator compartment so as to radiate the heat absorbed at theheat absorption part44a.The thermoelectric-module44 may be inserted between acold block46 and aheat sink70, both of which will be described later. A power supply unit (not shown) may be connected with the thermoelectric-module44.
• The thermoelectric-module44 may employ a Peltier effect, in that a DC voltage may be applied to two different kinds of metals which are combined to generate endothermic and exothermic phenomena. The thermoelectric-module44 may be formed of an extrinsic semiconductor, such as, for example, germanium, silicon, lead telluride, bismuth telluride, indium arsenic (InAs), or others as appropriate.
• Thecold block46 may be positioned inside thepanel40, that is, in theinner space16′ of thefirst door16. Thecold block46 may be attached to theheat absorption part44aof the thermoelectric-module44. As theheat absorption part44aof the thermoelectric-module44 gets cold, thecold block46 may transmit the cold air to theinner space16′.
• Theice maker50 may be provided in theinner space16′, and may be connected with thecold block46. Here, theice maker50 may make ice in a heat-insulated space formed by theinner space16′ using water supplied by awater supply part53. Theice maker50 may be directly connected with theheat absorption part44aof the thermoelectric-module44 to receive the cold air, and not directly connected with thecold block46.
• Theice maker50 may include anice tray52 and acontrol box56. Ice may be made from water held in theice tray52 and subjected to cold air. In certain embodiments, theice tray52 may be approximately semi-cylindrical shaped. A plurality of ribs may project upward from an inner portion of theice tray52, spaced apart from each other a predetermined distance, so as to separate the ice into separate pieces. In addition, a heater (not shown) may be provided, for example, under theice tray52, to heat the surface of theice tray52 for a relatively short time period, such that a surface of the ice attached to the surface of theice tray52 may be melted enough to be separated smoothly. Thewater supply part53 may be provided at a predetermined portion of theice tray52 to supply water to thetray52 for making ice.
• Atransfer plate54 may be provided at theice tray52. A first surface of thecold bock46 may closely contact the thermoelectric-module44, and a second surface of thecold block46 may closely contact thetransfer plate54. Thus, an appearance of thetransfer plate54 may correspond to the appearance of thecold block46. In alternative embodiments, if thetransfer plate54 is directly connected with the thermoelectric-module44, the appearance of thetransfer plate54 may correspond to the appearance of the thermoelectric-module44. Thetransfer plate54 may be formed integrally with theice tray52. Thetransfer plate54 may receive cold air from the thermoelectric-module44 directly or through thecold box46 from the thermoelectric-module44 and convey the cold air to theice tray52 in order to cool theice tray52. Thus, thetransfer plate54 may be formed of metal material having high heat conductivity.
• Thecontrol box56 may be provided in theice tray52, at a portion of theice tray52 opposite to where thewater supply part53 is provided, as shown inFIGS. 2-3, or other location as appropriate. Thecontrol box56 controls operation of theice maker50. A motor (not shown) may be provided in thecontrol box56 and an ejector (not shown) may be rotatably connected with a rotation shaft of the motor. A rotation shaft of the ejector may extend across a center of theice tray52, and a plurality of ejector pins (not shown) may be spaced apart a predetermined distance along the rotation shaft of the ejector. For example, each of the ejector pins may be arranged in a corresponding space which is partitioned off by the ribs.
• Thecontrol box56 may include an iceamount sensing arm58 that senses an amount of ice collected in an ice bank (not shown) provided beneath theice tray52. The iceamount sensing arm58 may be movable vertically upward and downward, and may be connected with a controller mounted in thecontrol box56. Theice maker50 may determine whether additional ice will be made according to the operation, and in particular, a position, of the iceamount sensing part58 and the controller.
• Afan60 may be installed in theinner space16′ of thefirst door16. Thefan60 may circulate cold air inside theinner space16′. In this embodiment, thefan60 is provided at a side of thecontrol box56. Thefan60 may face an upper or lower portion of theice tray52 to improve ice making speed. That is, thefan60 may increase the amount of cold air in contact with theice tray52, thus increasing the cooling speed of theice tray52.
• Theheat sink70 may be provided at the surface of the thermoelectric-module44 facing the refrigerator compartment. Theheat sink70 may expand a heat radiation area of the thermoelectric-module44, and may be positioned opposite thecold block46. That is, theheat sink70 may be installed toward the refrigerator compartment and closely contact theheat radiation part44bof the thermoelectric-module44. As a result, theheat sink70 may absorb heat generated from the thermoelectric-module44 and discharge the absorbed heat into the refrigerator compartment. That is, as theheat sink70 is exposed to the inside of the refrigerator compartment, theheat sink70 is cooled and theheat radiation part44bof the thermoelectric-module44 is cooled relatively fast. As a result, if the cooling period of the thermoelectric-module44 is reduced, the cooling efficiency of the thermoelectric-module44 may be improved.
• A coolingfan80 may be installed at a surface of thepanel40 which faces the inside of the refrigerator compartment. The coolingfan80 may face the surface of the thermoelectric-module44 or the surface of theheat sink70 that faces the refrigerator compartment. The coolingfan80 may be directly installed at the thermoelectric-module44 or theheat sink70. The coolingfan80 may blow cold air of the refrigerator compartment onto the thermoelectric-module44 or theheat sink70 to increase the heat radiation capacity of theheat sink70.
• In certain embodiments, heatconductive material45 may be coated between respective mating surfaces of thetransfer plate54, thecold block46, the thermoelectric-module44 and theheat sink70. The heat conductive material may expand respective contact areas between these components to maximize a heat conduction effect. The heat conductive material may be, for example, thermal grease, thermal powder, or other material as appropriate.
• Thecold block46 may be secured to theheat sink70 by a securing member47 that passes through thetransfer plate54 and thecold block46 sequentially. Alternatively, the securing member47 may pass through thepanel40 to directly secure thecold block46 and theheat sink70 to thepanel40.
• Next, an operation of the refrigerator having the above configuration will be described.
• First, the thermoelectric-module44 and theice maker50 are installed on thepanel40. Thepanel40 is then installed on an interior side of thedoor16 to selectively open and close the opening into theinner space16′ of thefirst door16. That is, theinner space16′ is formed by thefirst door16 and thepanel40. As a result, theinner space16′ is separated from the refrigerator compartment and forms the ice making chamber.
• The at least one thermoelectric-module44 is attached to a first surface of thecold block46 and thetransfer plate54 is attached to a second surface of thecold block46 opposite the first surface. Theheat sink70 is attached to a surface of the thermoelectric-module44 opposite thecold block46. At this time, thecold block46 closely contacts theheat absorption part44aof the thermoelectric-module44 and theheat sink70 closely contacts theheat radiation part44bof the thermoelectric-module44, thus forming heat transfer means. As mentioned above, heat conductive material is coated between thetransfer plate54 and thecold block46 before they are attached to each other.
• The securing member is then passed through thetransfer plate54, thecold block46 and thepanel40 sequentially, to be secured to theheat sink70. The securing member is tightly fastened to theheat sink70 so that the thermoelectric-module44 may be securely inserted between thecold block46 and theheat sink70.FIG. 3 illustrates theice maker50 and the thermoelectric-module44 secured to thepanel40. Thefan60 is installed in/on thecontrol box56 and the coolingfan80 is installed at theheat sink70 to control the flow of cold air in theinner space16′.
• Next, a process will be described in which theice maker50 and the thermoelectric-module44 are operated.
• If power is applied to the thermoelectric-module44, theice tray52 having been filled up with water by thewater supply part53, theheat absorption part44aof the thermoelectric-module44 absorbs heat and theheat radiation part44bradiates the absorbed heat. That is, theheat absorption part44aof the thermoelectric-module44 absorbs the heat of thetransfer plate54 through thecold block46. As the surface of thecold block46 gets cold, the cold air is transferred to thetransfer plate54 and next to theice tray52. Then, as theice tray52 is cooled, the ice making process is performed in theice maker50.
• At this time, theheat sink70 absorbs the heat generated from theheat radiation part44bof the thermoelectric-module44 and radiates heat into the refrigerator compartment. Then, the coolingfan80 installed at theheat sink70 blows cold air from the refrigerator compartment onto the thermoelectric-module44 and theheat sink70 to improve the cooling efficiency of the thermoelectric-module44.
• As theheat radiation part44bof the thermoelectric-module44 radiates heat quickly, the operation of theheat absorption part44amay be performed smoothly. As a result, if theheat radiation part44bof the thermoelectric-module44 is cooled by the cold air of the refrigerator compartment, the speed of the heat absorption performed at theheat absorption part44amay be increased, and thus the cooling efficiency of the thermoelectric-module44 may be improved.
• If the cooling system of the thermoelectric-module44 is applied to theinner space16′ which forms the ice making chamber as described above, a separate cold air duct that transfers cold air does not have to be provided in the door. As a result, a refrigerator as embodied and broadly described herein may have a simple structure, and a capacity of the refrigerator may be increased by the volume of the cold air duct which is no longer required. In addition, the thermoelectric-module44 does not generate frost, and thus cooling efficiency may be improved.
• The ice making chamber having a thermoelectric-module44 as embodied and broadly described herein may form a cooling space, separated from the refrigerator and freezer compartments. As a result, even if a failure of the operation of one of the compartments of the refrigerator occurs, the ice making chamber may be operated independently.
• Embodiments as broadly described herein may be applicable to a three-door bottom freezer type refrigerator in which refrigerator and freezer compartments are provided vertically, with two doors coupled to right and left sides of the refrigerator compartment, to a two-door bottom freezer type refrigerator having two doors coupled to the refrigerator and freezer compartments, respectively, to a top mount type refrigerator having the refrigerator and freezer compartments provided vertically, and to a side by side type refrigerator having the refrigerator and freezer compartments provided next to each other.
• In accordance with embodiments as broadly described herein, a thermoelectric-module requiring no cold air ducts, having a simple structure, may be used to cool an ice making chamber. As a result, utilization of space may be improved and a capacity of the refrigerator may be improved. In addition, energy efficiency may be enhanced because a heater is not required to remove frost from the cold air duct.
• Furthermore, in embodiments as broadly described herein, it may be possible to operate a thermoelectric-module fast and there is an advantage of improved cooling efficiency, because the heat radiation part of the thermoelectric-module is cooled by the cold air of the refrigerator compartment. Still further, the ice making chamber may be formed at a variety of positions because the ice making chamber has independent cooling by using the thermoelectric-module separated from the refrigerator and freezer compartments.
• A freezing cycle of a refrigerator may include, for example, a compressor, a condenser, an expansion valve and an evaporator. The compressor compresses low temperature/pressure gaseous refrigerant into a high temperature/pressure gaseous refrigerant. The condenser condenses the refrigerant drawn from the compressor, using external air. The expansion valve may have a relatively narrow diameter so as to expand the refrigerant drawn from the condenser. The evaporator absorbs heat generated while the refrigerant which has passed through the expansion valve is evaporated at a low pressure.
• Refrigerators may be categorized into top mount types and side by side types. In the top mount type, a refrigerator or freezer compartment is mounted one on top of the other, and refrigerator and freezer doors are respectively coupled to the compartments to open and close the compartments. In the side by side type, the refrigerator and freezer compartments are provided side by side, with refrigerator and freezer compartment doors rotatably coupled to two opposite sides of the refrigerator to respectively open and close the compartments.
• Various kinds of convenience devices, such as, for example, a home bar or dispenser that allows items received in an interior side of the door to be withdrawn without opening the doors.
• Refrigerators may also include an ice making chamber in the refrigerator or freezer compartment to make ice. Cold air generated in a cold air generation chamber may be moved into the ice making chamber via a cold air duct. However, in some circumstances, cold air having different temperatures may be mixed, thus generating frost at an outlet of the cold air duct that is in communication with the ice making chamber. Frost generated at an inner circumferential surface of the cold air duct may deteriorate refrigerant flow and thus cooling efficiency.
