Description

Insulator

[0001] The present invention relates to an insulator. The present invention relates to a refrigerator equipped with an insulator.

[0002] Japanese Patent Application Publication JP2013-002656A (published on January 7, 2013; hereinafter referred to as Patent Document 1) discloses a refrigerator capable of reducing the number of manufacturing processes.

[0003] The refrigerator disclosed in Patent Document 1 comprises an insulating case comprised of a vacuum insulation panel positioned between an outer case and an inner case. The inner case comprises a protrusion protruding into the refrigerator. The protrusion is formed integrally with the inner case. The protrusion comprises a shelf support portion, a guide rail installation portion, and a partition wall support portion, and can support and combine components such as shelves, drawers, and partition walls that are incorporated into the interior of the refrigerator. Patent Document 1 suffers from the problem of making it difficult to form the protrusion integrally with the inner case formed of a metal material.

[0004] Therefore, a separate component joint is required to join components such as shelves, drawers, and partition walls inside the refrigerator. When two vacuum insulation panels are assembled at a right angle, the inner cases of each vacuum insulation panel meet at the corners, and the corners of the metal inner cases each act as a heat bridge, causing a problem in that cold air (heat) inside the refrigerator leaks through the corners of the inner cases. In addition, according to patent document 1, a sheet member connecting part is formed integrally with the inner case of the vacuum insulation panel, but in this case, the sheet member connecting part is thicker than the thickness of the inner case, making it difficult to manufacture a vacuum insulation panel in which the sheet member connecting part and the inner case are formed integrally.

[0005] Therefore, a separate insulation member is required to minimize heat leakage at the corners of the refrigerator to which the vacuum insulation panel is applied.

[0006] The purpose of the present invention is to provide a refrigerator having a structure capable of solving the above-described problems.

[0010] The fourth purpose is to provide a refrigerator having a structure in which joint and insulation blocks can be uniformly adhered to a second case of a vacuum insulator.

[0011] The fifth object is to provide a refrigerator having a structure in which shelf hanging plates or drawer guides can be easily combined to provide parts such as shelves or drawers inside the refrigerator to which vacuum insulation panels are applied.

[0012] The sixth purpose is to provide a refrigerator having a structure in which joints and insulation blocks can be evenly attached to a second case of a vacuum insulator using internal components such as shelf hanging plates or drawer guides.

[0039] According to an embodiment of the present invention, the following effects can be achieved.

[0040] First, the body of the refrigerator is manufactured by assembling at least two panels made of vacuum insulation, and a joint made of insulation is placed at the corners where the plurality of vacuum insulation panels are connected to reinforce the insulation of the corners.

[0041] Second, bolt plates are installed on at least two panels, and bolt portions are formed protruding from the bolt plates. A joint is provided with a connecting portion having a connecting hole formed therein. The bolt portions penetrate the connecting holes of the connecting portions, and as a nut is connected to the bolt portions, the joint can be easily connected to the main body, such as the second panel, by the bolt plates.

[0042] Third, insulation blocks can be formed integrally at the joint. These blocks can expand the insulation area of ​​the joint. They can be placed in any space without affecting the refrigerator's high internal capacity.

[0043] Fourth, the insulating blocks can be joined by bolt plates installed on the main body. Joining holes are formed in the insulating blocks. The bolt portions of the bolt plates penetrate the joining holes of the insulating blocks, and as nuts are joined to the bolt portions, the insulating blocks can be easily joined to the main body, such as the second panel and the first panel, by the bolt plates.

[0044] Fifth, the sealing frame can be joined to an insulating block in which a joint or a joint is formed integrally. A joining hole is formed in the sealing frame. The bolt portion of the bolt plate passes through the joining hole of the insulating block and the joining hole of the sealing frame, and as the nut is joined to the bolt portion, the sealing frame can seal the insulating block to the surface of the main body. An extension rib can be extended along the length of the joint. The sealing frame presses the extension rib or presses the joint directly to seal the joint to the surface of the main body.

[0045] It can be tightly bonded with .

[0046] Sixth, components arranged inside the main body, such as shelves and drawers, can be connected to the main body by having separate component connection parts. A shelf hanger plate or drawer guide having a through hole can be easily connected to the main body by a bolt plate. The bolt portion of the bolt plate passes through the connection hole of the shelf hanger plate, and as a nut is connected to the bolt portion, the shelf can be easily connected to the main body. The bolt portion of the bolt plate passes through the connection hole of the drawer guide, and as a nut is connected to the bolt portion, the drawer guide can be easily connected to the main body.

[0047] Seventh, a portion of the sealing frame may be attached to the partition wall. Another portion of the sealing frame may be attached to the fourth block, which is an insulating block of the fourth panel. Since the sealing frame and the drawer guide are attached by the bolt portion of the bolt plate, the sealing frame can easily attach the drawer guide to the surface of the first panel.

[0048] Eighth, the sealing frame is joined to an insulation block formed integrally with the second storage chamber joint. This allows the sealing frame to easily join the second storage chamber joint or insulation block to the main body. Since the sealing frame does not require bolt plates, it not only prevents heat leakage through the corners, but also enhances insulation performance.

[0164] Through this, the joint (1164, 118, 124) can receive a pressing force from the component joint to press and close the joint (110) and the extension rib (114) toward the surface of the main body (100), that is, the first plate (1081) of the vacuum insulator (108).

[0165] , one side (e.g., left end or right end) of the extension rib (114) may be arranged to be connected in one direction to one side (e.g., right end or left end) of the bolt plate (109).

[0166] Through this, the extension rib (114) can be restricted from moving in one direction by the bolt plate (109). The joint portion can improve the adhesion between the extension rib (114) and the surface of the main body (100) and the joint (110).

[0167] The joint (110) can be divided into a first storage room joint (115) provided in the first storage room (105) and a second storage room joint (120) provided in the second storage room (106).

[0168] Referring to FIG. 7, the first storage joint (115) may include a first joint (116) arranged at a corner portion where the second panel (101) and the third panel (102) are connected.

[0174] A bolt portion (1095) arranged on a part of the first bolt plate (1091) can be connected to the first connecting portion (1164) by penetrating the connecting hole of the first connecting portion (1164). A connecting member such as a nut can be connected to the bolt portion (1095), so that the first joint (116) can be connected to the first plate (1081) of the second panel (101).

[0175] However, instead of a bolt plate (109) equipped with a bolt portion (1095), a nut plate equipped with a nut portion may be installed on the first plate (1081) of the second panel (101). In this case, a connecting member such as a bolt or the like may be connected to the nut portion, and the first joint (116) may be connected to the first plate (1081) of the second panel (101).

[0176] The first storage joint (115) may include a second joint (117) arranged at the corner where the second panel (101) and the first panel (103) are connected.

[0177] The second joint (117) is formed to be extended. The second joint (117) extends longer than the length of the first bolt plate (1091). The second joint (117) is positioned at the end of the second panel (101). Since the second joint (117) has a triangular cross-sectional shape and is similar to the configuration of the first joint (116), a duplicate description will be omitted.

[0182] A part of the second joint (117) may be connected to the surface of the partition wall (107; see Fig. 9).

[0183] An extension rib (114) may be further provided on the second surface of the second joint (117). The extension rib (114) may be formed to protrude in one direction (e.g., toward the left or right) at the point where the second surface and the third surface of the second joint (117) meet. The extension rib (114) may be formed integrally with the joint cover (111) of the second joint (117).

[0184] The extension rib (114) extends along the length of the second joint (117). One end of the extension rib (114) may be connected to or overlapped with one end of the first bolt plate (1091).

[0185] The first connecting portion (1164) of the first joint (116) is arranged to cover the first bolt plate (1091) and the extension rib (114) of the second joint (117), and a connecting member such as a nut is connected to the bolt portion (1095), so that the connecting force of the first joint (116), the second joint (117), and the first bolt plate (1091) can be firmly maintained.

[0186] , when the first connecting portion (1164) of the first joint (116) and the first bolt plate (1091) are connected, the first connecting portion (1164) presses the extension rib (114) of the second joint (117), thereby obtaining the effect of bringing the second joint (117) into close contact with the surface of the second panel (101) and the first panel (103).

[0187] The extension rib (114) wraps around one side of the first bolt plate (1091), thereby minimizing heat leakage through the bolt plate (109).

[0188] The first storage joint (115) may include a third joint (119) arranged at the corner where the third panel (102) and the first panel (103) are connected.

[0189] The third joint (119) is formed to extend in one direction of the first panel (103). The second joint (117) has a triangular cross-sectional shape, which is similar to the configuration of the first joint (116), so a duplicate description will be omitted.

The second joint (117) may support the first joint (116) and / or the third joint (119).

[0193] The first storage joint (115) can be assembled in the order of the second joint (117), the first joint (116), and the third joint (119).

[0194] Referring to FIGS. 7 and 8, the second storage joint (120) may include a first joint (121) arranged at a corner portion where the fourth panel (104) and the second panel (101) are connected.

[0198] The fourth panel exhaust port (1224) is accommodated in the receiving groove (1212). Through this, the first joint (121) surrounds the fourth panel exhaust port (1224), thereby blocking the connection of cold air between the fourth panel exhaust port (1224) and the second storage room (106), thereby improving insulation performance.

[0199] The second surface (1212) of the first joint (121) can be formed to be connected to the second panel (101). The second surface (1212) of the first joint (121) can form the surface of the first joint (121).

[0200] A plurality of holes (1214, 1216) may be formed sunken in the second surface (1212) of the first joint (121). Among the plurality of holes (1214, 1216), the first hole (1214) is an exhaust port receiving hole formed to exhaust air in order to form a vacuum insulator (108) of the second panel (101).

[0201] A second panel exhaust port (1215) is accommodated in the first hole (1214). Through this, the first joint (121) surrounds the second panel exhaust port (1215), thereby blocking the connection between the second panel exhaust port (1215) and the cold air of the second storage room (106), thereby improving the insulation performance.

[0202] Among the plurality of holes (1214, 1216), the second hole (1216) may be a hole for forming a suction line heat exchanger (hereinafter, SLHX) outlet. The suction line is a refrigerant pipe connected between the evaporator (148) and the compressor, and sucks the refrigerant that has passed through the evaporator (148) into the compressor. The SLHX is configured by welding a capillary tube to the outer surface of the suction line through soldering or the like. Through this, the SLHX connects the capillary tube and the suction line to each other on the suction side of the compressor by surface area to perform heat exchange.

[0203] The suction pipe heat exchanger outlet (1217) is accommodated in the second hole (1216). Through this, the first joint (121) surrounds the suction pipe heat exchanger outlet (1217), thereby blocking the connection between the suction pipe heat exchanger outlet (1217) and the cold air of the second storage room (106), thereby improving the insulation performance.

A penetrating portion (1220) may be formed to penetrate the center of the recessed portion (1219). A portion of the recessed portion (1219) (e.g., at least one of the left and right sides) is formed to be inclined in one direction (e.g., downward) from the support surface toward the penetrating portion (1220).

[0207] The defrost water generated in the evaporator (148) can be drained through the through-hole (1220). An overflow prevention plate (1221) is provided in a part (e.g., a front end) of the recessed portion (1219). The overflow prevention plate (1221) is formed to block one side of the recessed portion (1219). Through this, the overflow prevention plate (1221) can prevent the defrost water accumulated in the recessed portion (1219) from overflowing onto the surface of the first joint (121).

[0208] The fourth surface (1222) of the first joint (121) may form a part of the surface of the first joint (121). The fourth surface (1222) of the first joint (121) may be formed to be inclined downward from the third surface (1218). The fourth surface (1222) of the first joint (121) not only increases the internal volume of the high-temperature storage chamber, but also enables smooth convection of cold air in the second storage chamber (106).

[0209] The fifth side (1223) of the first joint (121) may form another portion of the side of the first joint (121). The fifth side (1223) of the first joint (121) may extend in one direction (e.g., vertically) from the fourth side (1222). The fifth side (1223) of the first joint (121) may provide one side for connection to an additional insulator.

[0210] Referring to FIG. 8, the second storage joint (120) may include a second joint (123) arranged at a corner portion where the first panel (103) and the second panel (101) are connected.

[0211] The second joint (123) may be positioned at the end of the second panel (101). The second joint (123) may be formed to be extended. The second joint (123) may have a polygonal cross-sectional shape. In the present embodiment, the second joint (123) is shown to have a heptagonal cross-sectional shape.

[0212] Among the seven sides of the second joint (123), the first side (1231) forms the side of the second joint (123). The first side (1231) of the second joint (123) can be formed to face and be connected to the side of the second panel (101).

[0213] The second surface (1232) of the second joint (123) may form a part (e.g., the left surface or the right surface) of the second joint (123). The second surface (1232) of the second joint (123) may be formed to face and be connected to a surface of one of the first panels (1031) or another of the first panels (1032).

[0214] The third surface (1233) of the second joint (123) extends from the first surface (1231). The third surface (1233) is arranged to face the second surface (1232) in one direction. The extension length of the third surface (1233) is smaller than the extension length of the first surface (1231) or the second surface (1232). The third surface (1233) of the second joint (123) is in contact with one side of the space that accommodates the evaporator (148), thereby preventing leakage of cold air (heat) generated from the evaporator (148).

[0215] The fourth surface (1234) of the second joint (123) extends from the third surface (1233) toward the second surface (1232). The fourth surface (1234) is arranged to face the first surface (1231) in one direction. The extension length of the fourth surface (1234) is shorter than the extension length of the first surface (1231) or the second surface (1232).

[0216] One side of the return duct can be arranged to be connected to the fourth side (1234). The return duct forms a path for cold air to be returned from the first storage room (105) to the second storage room (106).

[0217] The fifth side (1235) of the second joint (123) extends at an angle from one end of the fourth side (1234) to one end of the sixth side (1236), which will be described later, with respect to the fourth side (1234). The other side of the return duct may be arranged to be connected to the fifth side (1235).

[0218] The sixth surface (1236) of the second joint (123) extends from the other end of the fifth surface (1235). The sixth surface (1236) is arranged to face the second surface (1232). The extension length of the sixth surface (1236) is smaller than the extension length of the first surface (1231) or the second surface (1232). Another side of the return duct may be arranged to be connected to the sixth surface (1236).

[0219] The seventh surface (1237) of the second joint (123) extends from the second surface (1232). The seventh surface (1237) is arranged to face the first surface (1231) in one direction. The seventh surface (1237) is arranged to be connectable to one surface of an additional insulator.

[0220] A part of the second joint (123) can be connected so as to be connectable to the surface of the partition wall (107).

[0221] A third connecting portion (124) may be provided on the second joint (123). The third connecting portion (124) may be formed to protrude in one direction (e.g., left or right direction) from the first surface (1231) of the second joint (123). The third connecting portion (124) is formed in a plate shape. A connecting hole is formed in the third connecting portion (124). The third connecting portion (124) may be connected by a bolt portion (1095) protruding from a portion of the first bolt plate (1091) located on one side (e.g., lower side). The bolt portion (1095) penetrates the connecting hole of the connecting portion, and a nut is connected to the penetrated bolt portion (1095), so that the second joint (123) may be connected to the first plate (1081), which is a surface of the second panel (101).

[0222] The second storage joint (120) may include a third joint (127) arranged at the corner where the fourth panel (104) and the first panel (103) are connected.

[0223] The third joint (127) may be formed to extend in one direction from a portion (e.g., a front end) of the first joint (121). The third joint (127) may have a polygonal cross-sectional shape.

[0224] In this embodiment, the third joint (127) is shown as having a pentagonal cross-section. For example, the third joint (127) may include at least one of the first to fifth surfaces.

[0225] The first side is formed to be connected to the fourth panel (104). The second side is formed to be connected to the first panel (103). The third side extends in one direction from the first side and / or is arranged to face the second side. The height of the third side may be smaller than the height of the second side.

[0226] The fourth side is formed to be inclined from the third side toward the first panel (103). The fifth side is formed to extend from the fourth side toward the first panel (103). The fifth side is arranged to face the first side. The one-way length (e.g., left-right width) of the fifth side may be smaller than the one-way length (e.g., left-right width) of the first side.

[0227] A first panel exhaust port (1274) may be formed on the surface of the first panel (103). A first panel exhaust port receiving groove (1273) may be formed on the second surface of the third joint (127) of the second storage chamber joint (120). Through this, the third joint (127) surrounds the first panel exhaust port (1274), thereby blocking cold air from the first panel exhaust port (1274) and the second storage chamber (106) from being connected, thereby improving insulation performance.

[0228] The second storage joint (120) can be assembled in the order of the first joint (121) to the third joint (127). However, the order is not limited to this order.

[0229] A coupling protrusion (128) may be formed to protrude from the coupling portion (1164, 118, 124). The coupling protrusion (128) may be formed to protrude in a circular shape so as to surround the coupling hole. The inner wall of the coupling protrusion (128) may be formed in a polygonal shape such as a hexagon. Accordingly, when a coupling member such as a nut is coupled to the bolt portion (1095) after the bolt portion (1095) passes through the coupling hole, the inner wall of the coupling protrusion (128) surrounds the outer wall of the nut and engages, thereby preventing the nut from loosening.

[0230] , the joining projection (128) can reinforce the rigidity of the joining part when the plate thickness of the joining part is thin.

[0231] A gap may be formed between the outer wall of the coupling protrusion (128) and the third surface of the second joint (123). The reason for providing a gap between the outer wall of the coupling protrusion (128) and the third surface of the second joint (123) is to provide a tool insertion space for tightening the nut.

[0232] The coupling protrusion (128) can be applied not only to the first and second joints (121, 123) of the second storage room joint (120), but can also be applied in the same or similar manner to the first storage room joint (115).

[0233] A third plate (143)(129) can be attached to the first plate (1081). The third plate (143)(129) can reinforce the rigidity of the first plate (1081).

[0234] The third plate (129) can be arranged to overlap the bolt plate (109). This can reinforce the rigidity of the vacuum insulator (108) when the bolt plate (109) is bolted.

[0235] Since other components are the same or similar to the embodiments of FIGS. 1 to 13 described above, duplicate descriptions will be omitted.

A right end of the connecting wall (1323) is connected to a portion (e.g., a front end) of another one of the plurality of side walls (1321, 1322).

[0252] The plurality of side walls (1321, 1322) and connecting wall (1323) are each extended.

[0253] A through hole (1324) is formed to penetrate the connecting wall (1323) in one direction. At least two through holes (1324) may be spaced apart from each other in the connecting wall (1323).

[0254] The connecting projection of the shelf (130) can be inserted and connected into the insertion space between the side walls (1321, 1322) through the through hole (1324). Through this, the shelf (130) can be supported and connected to the connecting wall (1323).

[0463] This embodiment differs from the embodiments of FIGS. 1 to 26 described above in that the sealing frame (530) seals the second storage room joint (520) and / or the insulation block (522) to the surface of the second storage room (106).

[0464] However, this embodiment is similar to the embodiment of FIGS. 27 to 31 described above in that the second storage room joint (520) and / or the insulation block (522) are pressed together using at least two press frames (530) spaced apart from each other in one direction, but some structures of the press frames (530) are different from the embodiment of FIGS. 27 to 31 described above.

[0465] The component joint includes a sealing frame (530). The sealing frame (530) can be bonded to an insulating block (522). The sealing frame (530) can be formed in a plate shape. The sealing frame (530) can extend from the insulating block (522) between the surface of the partition wall and the surface of the fourth block portion (540). At least two sealing frames (530) can be arranged spaced apart from each other in one direction of the insulating block (522).

[0466] A coupling portion (531) may be provided on at least one of one side and the other side of the contact frame (530). The coupling portion (531) may extend from one side of the contact frame (530). A coupling hole may be formed in the coupling portion (531). A coupling member, such as a screw, may be coupled to the partition wall and the fourth block portion (540) through the coupling hole.

[0467] Through this, a part of the sealing frame (530) can be coupled to the partition wall and / or another part of the sealing frame (530) can be coupled to the fourth block section (540).

[0468] A frame joining groove may be formed in the insulating block (522). The frame joining groove may be formed concavely to correspond to the sealing frame (530). The frame joining groove may be an extension of the insulating block (522). The sealing frame (530) may be inserted and joined into the frame joining groove.

[0469] Through this, the frame joint groove can limit the movement of the contact frame (530) in one direction. When the contact frame (530) is inserted and connected into the frame joint groove, one side of the contact frame (530) and the side of the insulation block (522) can form the same plane.

[0470] In addition, the sealing frame (530) can seal the insulating block (522) and / or the second storage room joint (520) to the surface of the first panel (103).

[0471] , the sealing frame (530) can limit the insulation block (522) and / or the second storage joint (520) from moving in one direction.

[0472] At least one of the two sealing frames (530) can be connected to the insulating block (522) by a connecting member such as a screw. In this embodiment, the sealing frame (530) located at the part where the second joint (521) of the second storage room joint (520) and the insulating block (522) are connected is shown connected by a connecting member.

[0473] A connecting frame (533) may be placed between at least two sealing frames (530). The connecting frame (533) may extend in one direction along the insulating block (522). The connecting frame (533) may connect at least two sealing frames (530).

[0474] A second storage drawer guide (534) may be coupled to the insulation block (522). The second storage drawer guide (534) may extend in one direction along the insulation block (522). At least two second storage drawer guides (534) may be spaced apart from each other on the insulation block (522).

[0475] The drawer guide (534) may be provided with a guide protrusion (5341). The guide protrusion (5341) may extend in the longitudinal direction of the drawer guide (534). A receiving portion (5342) may be formed between at least two guide protrusions (5341). An insertion protrusion may be formed to protrude from the side of the drawer. The insertion protrusion of the drawer may be inserted into and engaged with the receiving portion (5342) when the drawer is drawn in and out.

[0476] The second storage drawer guide (534) can intersect with the contact frame (530) in one direction (e.g., perpendicular to each other). The second storage drawer guide (534) can be arranged to cover the contact frame (530). In this way, the second storage drawer guide (534) can restrict the contact frame (530) from moving in one direction.

[0477] The second storage drawer guide (534) can be coupled to the insulation block (522) by a coupling member such as a screw or the like. A coupling hole (428) can be formed on one side (e.g., front end) and / or the other side (e.g., rear end) of the second storage drawer guide (534). The coupling member penetrates the coupling hole (428) of the drawer guide (534) and the coupling hole (428) of the insulation block (522) to be coupled, thereby allowing the drawer guide (534) and the insulation block (522) to be coupled to each other.

[0478] , the sealing frame is bonded by sealing the insulating block (522) to the surface of the first panel (103), so that the insulating block (522) and the second storage drawer guide (534) can be bonded to the first panel (103).

[0479] Since other components are the same or similar to the embodiments of FIGS. 1 to 32 described above, duplicate descriptions will be omitted.

[0480] Figure 33 is a conceptual diagram showing the appearance before and after a partition wall (620) is joined to an insulating block (522) of a second storage room (106) according to another embodiment of the present invention.

[0481] The insulating block (522) located in the second storage room (106) can be further extended in one direction to surround at least one of one side and the other side of the partition wall (620).

[0482] An insertion groove (624) into which an end (e.g., a left or right end) of a partition wall (620) is inserted and joined can be formed on the surface of the insulation block (522).

[0483] The insertion groove (624) may extend in one direction of the insulation block (522). The one-way length (e.g., vertical width) of the insertion groove (624) may be formed to become narrower from one side (e.g., front end) to the other side (e.g., rear end) of the third insulation block (523).

[0484] A side guide portion (621) may be formed to protrude in one direction from a portion (e.g., left or right side) of the partition wall (620). The side guide portion (621) may be formed to correspond to the insertion groove (624). The one-way length (e.g., vertical width) of the side guide portion (621) may be formed to become narrower from one side (e.g., front end) of the insulation block (522) to the other side (e.g., rear end).

[0485] Through this, the side guide portion (621) of the partition wall (620) can be easily inserted and connected into the insertion groove (624).

[0486] When the partition wall (620) is inserted and joined between at least two insulating blocks (522) located on each of the left and right sides of the first panel (103), the insulating blocks (522) can be tightly joined to the surface of the first panel (103).

[0487] A duct connection portion (622) may be formed to penetrate a portion (e.g., the rear end) of the partition wall (620). The duct connection portion (622) is a hole that forms a passage for connecting the evaporator receiving portion (5342) (424) of the second storage chamber (106) and the multi-duct of the first storage chamber (105). The duct connection portion (622) may be arranged in a portion (e.g., the central portion of the rear end) of the partition wall (620).

[0488] A return duct forming portion (623) may be formed in a portion of the partition wall (620) (e.g., the left and / or right end of the rear end). The return duct forming portion (623) may be formed to be sunken in a portion of the partition wall (620) (e.g., the left and / or right end of the rear end). The return duct forming portion (623) forms a flow path connecting the first storage chamber (105) and the second storage chamber (106) so that cold air from the first storage chamber (105) is circulated to the second storage chamber (106).

[0489] Since other components are the same or similar to the embodiments of FIGS. 1 to 32 described above, duplicate descriptions will be omitted.

[0490] Accordingly, according to the present invention, a refrigerator body (100) is manufactured by assembling at least two panels (101, 102, 103, 104) made of vacuum insulation, and a joint (110) made of insulation material (112) is arranged at a corner portion where a plurality of vacuum insulation panels are connected to reinforce insulation of the corner portion.

[0491] Second, a bolt plate (109) is installed on at least two panels (101, 102, 103, 104), and a bolt portion (1095) is formed protrudingly on the bolt plate (109). A joint (110) is provided with a coupling portion (1164, 118, 124) having a coupling hole formed therein. The bolt portion (1095) penetrates the coupling hole (428) of the coupling portion, and as the nut is coupled to the bolt portion (3281), the joint (110) can be easily coupled to the main body (100), such as the second panel (101), by the bolt plate.

[0492] Third, insulation blocks (230, 323, 427, 439) can be integrally formed at joints (220, 320, 420). The insulation blocks (230, 323, 427, 439) can expand the insulation area of ​​the joints (220, 320, 420). The insulation blocks (230, 323, 427, 439) can be arranged in a space that does not change the high internal capacity of the refrigerator.

[0493] Fourth, the insulating block (230) can be joined by a bolt plate (229) installed on the main body (100). A joining hole is formed in the insulating block (230). The bolt portion (2291) of the bolt plate (229) penetrates the joining hole of the insulating block (230), and as the nut is joined to the bolt portion (2291), the insulating block (230) can be easily joined to the main body (100), such as the second panel (101) and the first panel (103), by the bolt plate (229).

[0494] Fifth, the sealing frame (330, 430, 530) can be coupled to the joint (320, 420, 520) or the insulating block (522) in which the joint (320) is integrally formed. A coupling hole (428) is formed in the sealing frame (330, 430, 530). The sealing frame (330, 430, 530) can be coupled to the main body (100) by a bolt plate (328) or without a bolt plate. Since a coupling member such as a screw is coupled by penetrating the coupling hole of the insulating block (427, 439, 522) and the coupling hole (428) of the sealing frame (430, 530), the sealing frame (430, 530) can tightly couple the insulating block (427, 439, 522) to the surface of the main body (100) without a bolt plate. Extension ribs (114, 125) can be extended along the longitudinal direction of the joints (320, 420, 520). The close-fitting frame (330, 430, 530) can press the extension ribs (114, 125) or directly press the joint (320) to close-fit the joint (320) to the surface of the main body (100).

[0495] Sixth, components arranged inside the main body (100), such as shelves (130), drawers, etc., can be coupled to the main body (100) by having a separate first component coupling portion (131). The first component coupling portion (131) having a through hole (1324) or a drawer guide (1411, 1421) can be easily coupled to the main body (100) by means of a bolt plate (109). The bolt portion (1095) of the bolt plate (109) passes through the coupling hole of the first component coupling portion (131), and as the nut is coupled to the bolt portion (1095), the shelf (130) can be easily coupled to the main body (100). The bolt portion (1091, 2291) of the bolt plate (109, 229) passes through the joining hole of the drawer guide (1411, 1421, 227, 228), and as the nut is joined to the bolt portion (1091, 2291), the drawer guide (1411, 1421, 227, 228) can be easily joined to the main body (100).

[0496] Seventh, a part of the sealing frame (430, 530) can be joined to the partition wall (620). Another part of the sealing frame (430, 530) can be joined to the fourth block portion (440, 540), which is an insulating block (439, 522) of the fourth panel (104). Since the drawer guide (429, 534) is joined to the insulating block (439, 522) by a joining member such as a screw, the sealing frame (530) can easily join the insulating block (439, 522) and / or the drawer guide (429, 534) to the surface of the first panel (103).

[0497] Eighth, the sealing frame (430, 530) is connected to an insulating block (439, 522) formed integrally with the second storage joint (520). Through this, the sealing frame (430, 530) can easily connect the second storage joint (520) or the insulating block (439, 522) to the main body (100). Since the sealing frame (430, 530) does not require a bolt plate, it not only blocks heat leakage through the corners, but also is advantageous in improving insulation performance.
