Abstract
Description
- This application is based on priority from Korean Patent Application No. 10-2016-0043427, filed on Apr. 8, 2016, the disclosure of which is incorporated herein in its entirety by reference for all purposes.
- The present disclosure relates to refrigerators, and more particularly, to ice-making mechanisms in refrigerators.
- A refrigerator is an electrical appliance that maintains a storage space at low temperature for storing food or other objects in a fresh or frozen state.
- The internal storage of the refrigerator can be cooled to a preset low temperature through circulation of cold air that is continuously generated through refrigeration cycles using a refrigerant, a refrigeration cycle including compression, condensation, expansion and evaporation.
- Top-mount-type refrigerators having a freezer positioned on a top of refrigeration chamber used to be the popular style. In recent years, however, bottom-freezer-style refrigerators have become more popular, in which a freezer is positioned under the refrigeration chamber. This style makes it easier for a user to access the refrigeration chamber but harder to access the freezer because the user typically has to bend down to open the freezer.
- To solve such a problem, some bottom-freezer-type refrigerators have an ice dispenser installed in a refrigeration chamber door at the upper side of the refrigerator. An ice-maker is installed on the interior side of the refrigeration chamber.
- An ice-maker in related art includes a heat insulation structure for preventing a temperature increase caused by heat exchange of an internal cold air with an external air.
FIG. 6 shows an ice-maker in the related art including a heat insulation structure. - As shown in
FIG. 6 , aheat insulation member 22 a is disposed in the contact region between the ice-maker and an inner wall surface of arefrigerator 2. Theheat insulation member 22 a is adjacent to, and follows the same path as, aheat insulation structure 24 of therefrigerator 2. - However, in this configuration, a dead space is formed within the
refrigerator 2, the dead space being occupied by the ice-maker and not used for storage. This causes the internal capacity of the refrigerator to become smaller. - In addition, it is difficult to seal a gap between the ice-
maker 20 and the inner wall surface of therefrigerator 2. Poor sealing leads to dew formation which negatively affects refrigeration performance. - Embodiments of the present disclosure provide a refrigerator capable of effectively sealing a gap between an ice-maker and an inner wall surface of the refrigerator without reducing an internal capacity of the refrigerator.
- The present disclosure provides a refrigerator comprising: a case mounted to a refrigerator main body; and an ice tray within the case and configured to store water for making ice, wherein the case includes: a first external frame coupled to an inner wall surface of the refrigerator main body and having a first step portion extending along an edge of one surface of the first external frame facing the inner wall surface of the refrigerator main body; a second external frame coupled to the first external frame to form an outer shell of the case and having a second step portion extending along an edge of one surface of the second external frame facing a ceiling surface of the refrigerator main body; and a sealing member coupled to the first step portion and the second step portion, the sealing member configured to continuously extend along the first step portion and the second step portion and to form a closed loop.
- Further, the present disclosure also provides a refrigerator, wherein the first step portion and the second step portion protrude from the first external frame and the second external frame so as to shield the sealing member when the case is coupled to the refrigerator main body.
- Further, the present disclosure also provides a refrigerator, wherein the first step portion makes surface-to-surface contact with the inner wall surface of the refrigerator main body, and the second step portion makes surface-to-surface contact with the ceiling surface of the refrigerator main body.
- Further, the present disclosure also provides a refrigerator, wherein a heater is disposed inside of at least one of the first step portion and the second step portion.

FIGS. 1 to 4 , therefrigerator 1 having an ice-maker 10 according to one embodiment of the present disclosure may include a refrigeratormain body 12 serving as an outer shell (or exterior housing) of therefrigerator 1, abarrier 14 configured to divide the interior of the refrigeratormain body 12 into an upper refrigeration chamber R and a lower freezer F,refrigeration chamber doors 13 mounted on a front edge of the refrigeratormain body 12 and configured to cover the refrigeration chamber R, and afreezer door 15 configured to cover the freezer F. - In the illustrated embodiment of the present disclosure, the ice-
maker 10 is on one side of an upper region of the refrigeration chamber R. However, this is merely exemplary. An ice-maker may be located in another portion of a refrigerator. - The ice-
maker 10 may make close contact with an inner wall surface of the refrigeratormain body 12. The ice-maker 10 may include acase 100, a cooling system (not shown), an ice-making assembly 200, anice bucket 320, a feeder assembly 400 and anejection part 500. - The
case 100 is a housing and may be installed to make close contact with the inner wall surface of the refrigeratormain body 12. For example, the ice-making assembly 200 is inside thecase 100 and produces ice. Produced ice may be discharged through a hole of theejection part 500. Cold air for producing ice may be supplied through a cold air supply port (not shown) in the other end portion of thecase 100. - The
case 100 may include, for example, a firstexternal frame 110 coupled to the inner wall surface of the refrigeratormain body 12, and a secondexternal frame 120 coupled to the firstexternal frame 110, where the secondexternal frame 120 defines the overall external shape of thecase 100. - The first
external frame 110 may be fastened to the inner wall surface of the refrigeratormain body 12. For example, the firstexternal frame 110 may be fastened to the inner sidewall of the refrigeratormain body 12, such as by screw fixing, bonding or other fastening methods well known in the art. - The first
external frame 110 may have an upper end portion and a lower end portion. For example, the firstexternal frame 110 may have an approximately C-like cross-sectional in general. - A
first step portion 111 may be disposed in an edge of one surface of the firstexternal frame 110 facing the inner wall surface of the refrigeratormain body 12. For example, thefirst step portion 111 may protrude toward the inner surface of the refrigeratormain body 12. A sealingmember 160 may be bonded to anupper surface 111 a of thefirst step portion 111. The sealingmember 160 may prevent dew formation potentially caused by the temperature between the inside and the outside of the case. - A heater (not shown) may be disposed in the
first step portion 111 and can evaporate dew formed in or around thefirst step portion 111. The heater may be injection-molded inside thefirst step portion 111 or may be bonded to the inside or the outside of thefirst step portion 111. - The second
external frame 120 may be coupled to the firstexternal frame 110 and form an outer shell of thecase 100. - A
fastening portion 122 may be disposed at the front end of the secondexternal frame 120. Theelection part 500 may be coupled to thefastening portion 122. Furthermore, afastening portion heater 150 may be disposed in thefastening portion 122 to evaporate dew formed in or around thefastening portion 122. - Additionally, a
second step portion 121 may be disposed on one surface of the secondexternal frame 120 facing an inner ceiling surface of the refrigeratormain body 12 and extend along an edge of the secondexternal frame 120. For example, thesecond step portion 121 may protrude along an edge of one surface of the secondexternal frame 120 facing the inner ceiling surface of the refrigeratormain body 12. A sealingmember 160 may be disposed oninner surface 121 a of thesecond step portion 121. As noted above, the sealingmember 160 may prevent dew formation. - Descriptions will now be made on the configurations of the sealing
member 160 in particular, thefirst step portion 111 and thesecond step portion 121. The sealingmember 160 may be made of an elastic material such as rubber or the like and may continuously extend along thefirst step portion 111 and thesecond step portion 121. In other words, the sealingmember 160 may continuously extend along the edge of thecase 100, which makes contact with the refrigeratormain body 12, and may form a closed loop. - In this case, the sealing
member 160 may be coupled to the inside of thefirst step portion 111 and thesecond step portion 121. Thus, with thecase 100 coupled to the refrigeratormain body 12, the sealingmember 160 may not be exposed to the outside. - In other words, the
first step portion 111 and thesecond step portion 121 may protrude toward the inner wall of the refrigeratormain body 12 and may shield the sealingmember 160 with thecase 100 coupled to the refrigeratormain body 12. - Furthermore, during manufacturing, the
case 100 may be coupled to the refrigeratormain body 12 after the sealingmember 160 is bonded to thefirst step portion 111 and thesecond step portion 121. Accordingly, installing the sealingmember 160 becomes easier compared with the method of coating a sealingmember 160 after thecase 100 is coupled to the refrigeratormain body 12 or the method of coupling thecase 100 to the refrigeratormain body 12 after a sealing member bonded to the inner wail of the refrigeratormain body 12. - The
first step portion 111 and thesecond step portion 121 may protrude to make surface contact with the inner wall surface and the ceiling surface of the refrigeratormain body 12. This can enhance the heat insulation properties provided by thecase 100. Thus, dew formation caused by the temperature difference between the inside and the outside of thecase 100 can be effectively prevented. In addition, one or more heaters may be installed inside thefirst step portion 111 and thesecond step portion 121 to facilitate dew evaporation in thefirst step portion 111 and thesecond step portion 121. - A
heat insulation frame 140 may be installed inside the secondexternal frame 120. Theheat insulation frame 140 may be made material having superior heat insulation performance, such as a urethane foam or the like. Theheat insulation frame 140 may be manufactured by foaming and solidifying a raw material within a mold for example. - The
heat insulation frame 140 may be formed in an L-like cross-sectional shape and used to insulate the outer side of the ice-maker 10, which does not make contact with the refrigeratormain body 12 when the ice-maker 10 is mounted to the refrigeratormain body 12. - An
internal frame 130 may be provided at the inner side of theheat insulation frame 140. Theheat insulation frame 140 may be fixed by theinternal frame 130. In other words, theheat insulation frame 140 may be disposed between theinternal frame 130 and the secondexternal frame 120. - By fastening the
internal frame 130 and the secondexternal frame 120 together, theheat insulation frame 140 can be fixed between theinternal frame 130 and the secondexternal frame 120. - With such configuration of the L-shaped heat insulation frame, the internal capacity of the refrigerator can be increased. The first
external frame 110 disposed at the side of the inner wall of the refrigeratormain body 12 is not provided with a separate heat insulation frame because the refrigeratormain body 12 is provided with a heat insulation material. Rather, theheat insulation frame 140 is only provided at the outer side of the ice-maker 10 which does not make contact with the refrigeratormain body 12. A dead space as present in therefrigerator 1 can be reduced and therefore the internal capacity of therefrigerator 1 is advantageously enlarged. - A cooling system (not shown) is used to supply cold air to an
ice tray 210. Any cold air generation device that is well known in the art may be used in the cooling system. - Specifically, the cooling system may include a compressor, a condenser, an expansion valve and an evaporator, and execute cooling cycles. The cooling system may generate cold air through heat exchange between a refrigerant with air. The cold air thus generated may be supplied to the
ice tray 210 by a blow fan or the like via aninjection duct 310 coupled to the cold air supply port of thecase 100 and a coldair guide part 220. - The ice-making
assembly 200 may include anice tray 210 configured to store water, a coldair guide part 220 configured to guide a flow of cold air supplied from the cooling system so that the cold air moves along a lower surface of theice tray 210, and arotation part 230 configured to rotate theice tray 210 so that ice formed in theice tray 210 can drop out from theice tray 210. - The
ice tray 210 may include a plurality of ice-making spaces for storing water and may receive water from an external water source (not shown). After water is filled in theice tray 210, cold air generated by the cooling system is supplied to theice tray 210 to produce ice. - The
ice tray 210 may be made of a metal having high heat conductivity to enhance ice production efficiency. For example, theice tray 210 may be made of aluminum (Al). In addition, ribs (not shown) for increasing the contact area of theice tray 210 with the cold air may be formed on the lower surface of theice tray 210. - The cold
air guide part 220 serves to guide the cold air supplied from the cooling system toward the lower side of theice tray 210. The coldair guide part 220 may be coupled to aninjection duct 310. Furthermore, the coldair guide part 220 may include first and second coldair guide members injection duct 310. The first coldair guide member 221 may extend from the upper surface of theinjection duct 310. The second coldair guide member 222 may extend from the lower surface of theinjection duct 310. - The first cold
air guide member 221 may be coupled between the upper surface of theinjection duct 310 and abracket 211 to which theice tray 210 is mounted. The second coldair guide member 222 may extend from the lower surface of theinjection duct 310 and may be spaced apart from the lower surface of theice tray 210. Thus, a coldair flow path 225, through which the cold air can move, may be formed between the lower surface of theice tray 210 and the second coldair guide member 222. - The
rotation part 230 may be used to transfer ice from theice tray 210 to theice bucket 320 disposed below theice tray 210. For example, the upper surface of theice tray 210 may be rotated toward theice bucket 320 as a rotary shaft 231 rotates. At this time, if theice tray 210 is rotated by a specified angle or more, theice tray 210 is twisted by an interference member (not shown). Due to the twisting action of theice tray 210, the ice contained in theice tray 210 may fall into theice bucket 320. Various other methods that are well known in the art may be employed as a method of transferring the ice from theice tray 210. - The feeder assembly 400 serves to feed the ice toward the
election part 500. The feeder assembly 400 may include anauger 410 and anauger motor 420. Theauger 410 may be accommodated within theice bucket 320. As theauger 410 rotates, ice stacked in theice bucket 320 may be fed to theejection part 500. Theauger 410 may be rotated by theauger motor 420 provided in anauger housing 430. - Although exemplary embodiments of the present disclosure are described above with reference to the accompanying drawings, those skilled in the art will understand that the present disclosure may be implemented in various ways without changing the necessary features or the spirit of the present disclosure.
- Therefore, it should be understood that the exemplary embodiments described above are not limiting, but only an example in all respects.
