Optionally, the present disclosure may include a second panel forming a second surface (e.g., rear surface) of the refrigerator. Optionally, the present disclosure may include a third panel forming a third surface (e.g., top surface) of the refrigerator. Optionally, the present disclosure may include a fourth panel forming a fourth surface (e.g., bottom surface) of the refrigerator. Each of the first, second, third, and fourth panels may be provided in a plural form. The panel may be a heat insulator or a vacuum heat insulator. The first panel may include one of the first panels forming one of the first surfaces of the refrigerator, and the other one of the first panels forming the other one of the second surfaces of the refrigerator. At least one of the first, second, third, and fourth panels may provide at least a portion of a wall forming a storage chamber of the refrigerator. At least one of the first, second, third, and fourth panels may provide at least a portion of a wall forming a main body of the refrigerator.

[0013] A refrigerator according to an embodiment of the present disclosure includes a main body. The main body includes a second storage chamber. The main body includes a first plate, a second plate, and a support. The first plate is disposed toward the second storage chamber. The second plate is disposed toward an outer side of the second storage chamber. The support forms a vacuum space between the first plate and the second plate, and supports the first plate and the second plate. The main body includes a second storage chamber joint and / or a component coupler. The second storage chamber joint includes a different material from the first plate. The second storage chamber joint is disposed at a corner portion where at least two panels forming the second storage chamber are connected. The component coupler couples the second storage chamber joint to the first plate at the corner portion. According to such a configuration, the second storage chamber joint may reinforce heat insulation of a corner portion where a plurality of vacuum heat insulators are connected. It is possible to easily couple the joint and additional heat-insulating blocks through the component coupler.

[0014] A coupler is formed to protrude from one side of the second storage chamber. The coupler includes a coupling hole. The component coupler includes a bolt plate and a bolt. The bolt plate is coupled to the first plate. The bolt protrudes from the bolt plate. The bolt penetrates the coupling hole. A nut is coupled to the bolt. Accordingly, the second storage chamber joint may be easily coupled through coupling of the bolt plate and the coupler.

[0015] The component coupler includes a support part and a catching part. The support part is coupled to the bolt plate by the bolt. The support part is configured to support the evaporator. The catching part is formed to protrude from the support part in a ring shape to catch a portion of the evaporator. Through this, the catching part of the component coupler may easily install and dismantle the evaporator.

[0016] The component coupler includes a first movement limiter that extends from an corner portion of the support part in one direction (e.g., forward) to limit one-direction movement of the second storage chamber joint. The component coupler may include a second movement limiter that limits the other one-direction movement of the second storage chamber joint. The second movement limiter may be formed to extend in one direction to cover a portion of the second storage chamber joint on one side of the first movement limiter. Through this, the component coupler may support the second storage chamber joint in various directions.

[0017] The first joint includes a recess part formed to be inclined from a peripheral portion of one surface of the first joint toward a central portion of one surface of the first joint. The first joint may include a penetration part formed to penetrate a central portion of the recess part in one direction to discharge condensed water generated by the evaporator to the outside. Through this, the penetration part of the second storage chamber joint may discharge the condensed water generated by the evaporator to the outside.

[0018] The component coupler may include a third plate coupled to the first plate to cover the second storage chamber joint. Through this, the third plate may couple the second storage chamber joint more firmly.

[0019] The first plate and the second storage chamber joint may be provided with different materials. The first plate is formed of a metal material, and the second storage chamber joint may include at least one heat-insulating material of PU, ABS, and EPS. Through this, the heat insulation performance of the refrigerator may be improved.

[0020] The refrigerator may include a heat-insulating block extending from a corner portion where the at least two panels are connected. Through this, the heat-insulating block may expand a heat insulation area of the refrigerator without affecting an internal volume of the refrigerator.

[0021] The heat-insulating block may be provided as a component separated from the second storage chamber joint and coupled thereto, or may be formed integrally therewith. Through this, the second storage chamber joint and the heat-insulating block may be easily installed and dismantled.

[0022] A plurality of contact frames may be provided. The plurality of contact frames may be disposed to be spaced apart from each other in one direction along one surface of the heat-insulating block. Through this, the close-contact frames may closely contact and support a portion (e.g., a front portion and / or a rear portion) of the heat-insulating block.

[0023] Optionally, the present disclosure may include a drawer guide coupled to one surface of the heat-insulating block, and formed to protrude to guide movement of a drawer introduced into or withdrawn from the second storage chamber. The contact frame may be disposed between the heat-insulating block and the drawer guide. Through this, the contact frame may closely contact the drawer guide together with the heat-insulating block.

[0024] Optionally, the present disclosure includes a first storage chamber and a second storage chamber. Optionally, the present disclosure includes a second storage chamber joint disposed at a corner portion where the plurality of panels forming the second storage chamber are connected. The heat-insulating block may be provided that is formed integrally with the second storage chamber joint or provided as a separate component and coupled to the separate component to cover the first panel and the second panel and one surface of the fourth panel. A contact frame may be provided that is coupled to one surface of the heat-insulating block and brings the second storage chamber joint and the heat-insulating block into close contact with one surface of the refrigerator main body. Through this, the contact frame may easily couple the second storage chamber joint or the heat-insulating block. The contact frame does not require a bolt plate, thereby not only blocking heat leakage through the corners but also being advantageous for improving the heat insulation performance.[Advantageous Effects]

[0025] According to embodiments of the present disclosure, the following effects can be achieved.

[0026] First, at least two panels including vacuum heat insulators are assembled to manufacture the main body of the refrigerator, and the joint including the heat-insulating material is disposed at corner portions where the plurality of vacuum heat insulator panels are connected to reinforce heat insulation of the corner portions.

[0027] Second, the bolt plate may be installed on one surface of the at least two panels, and the bolt is formed to protrude from the bolt plate. The joint is provided with the couplers including coupling holes formed therein. The bolt penetrates the coupling hole of the coupler, and as a nut is coupled to the bolt, the joint may be easily coupled to one surface of the main body 100 such as the second panel by the bolt plate.

[0028] Third, the heat-insulating blocks may be integrally formed with the joints. The heat-insulating blocks may extend a heat insulation area of the joints. The heat-insulating blocks may be disposed by utilizing a space that does not change the internal volume of the refrigerator.

[0029] Fourth, the heat-insulating block may be coupled by the bolt plate installed on one surface of the main body. The coupling hole is formed in the heat-insulating block. The bolt of the bolt plate penetrates the coupling hole of the heat-insulating block, and as the nut is coupled to the bolt, the heat-insulating block may be easily coupled to one surface of the main body such as the third panel, the first panel, and the second panel by the bolt plate.

[0030] Fifth, the contact frames may be coupled to one surface of the joints or the heat-insulating block in which the joint is integrally formed. The coupling holes are formed in the contact frames. As the bolt of the bolt plate penetrates the coupling holes of the heat-insulating blocks and the coupling holes of the contact frames, and the nut is coupled to the bolt, the contact frames may closely couple the heat-insulating blocks to one surface of the main body. The extension ribs may extend in the lengthwise direction of the joints. The contact frames may closely couple the joint to one surface of the main body by pressing the extension ribs or directly pressing the joint.

[0031] Sixth, components disposed inside the main body, for example, a shelf , a drawer, etc., may be provided with a separate component coupler to be coupled to one surface of the main body. The shelf catching plate or drawer guide including a penetration hole may be easily coupled to one surface of the main body by the bolt plate. The bolt of the bolt plate penetrates the coupling hole of the shelf catching plate, and as the nut is coupled to the bolt, the shelf may be easily coupled to one surface of the main body. The bolts of the bolt plates penetrate the coupling holes of the drawer guides, and as nuts are coupled to the bolts, the drawer guides may be easily coupled to one surface of the main body.

[0032] Seventh, the end portions of the contact frames may be coupled to the partition wall, the end portions of the contact frames may be coupled to the fourth block parts which are the heat-insulating blocks of the fourth panel, and the contact frames and the drawer guides are coupled to each other by the bolt of the bolt plate, so that the contact frame may easily closely couple the drawer guides to one surface of the first panel and the second panel.

[0033] Eighth, the contact frames are coupled to one surface of the heat-insulating blocks formed integrally with the second storage chamber joint. Through this, the contact frame may easily couple the second storage chamber joint or the heat-insulating block to one surface of the main body. The contact frame does not require a bolt plate, thereby not only blocking heat leakage through corners but also being advantageous for improving the heat insulation performance.[Description of Drawings]

[0114] Accordingly, the couplers 1164, 118, and 124 may receive a pressing force from the component coupler to press and bring the joint 110 and the extension rib 114 toward and into close contact with one surface of the main body 100, i.e., the first plate 1081 of the vacuum heat insulator 108.

[0115] One side (e.g., a left end or a right end) of the extension rib 114 may be disposed to be connected to one side (e.g., a right end or a left end) of the bolt plate 109 in the Y-axis direction.

[0116] Accordingly, the extension rib 114 may be restricted from moving in the Y-axis direction by the bolt plate 109. The coupler may improve adhesion between one surface of the main body 100 and the joint 110.

[0117] The joint 110 may be divided into a first storage chamber joint 115 provided on one surface of the first storage chamber 105 and a second storage chamber joint 120 provided on one surface of the second storage chamber 106.

[0118] Referring to FIG. 7, the first storage chamber joint 115 may include a first joint 116 disposed at a corner portion where the second panel 101 and the third panel 102 are connected.

[0119] The first joint 116 is formed to extend in the Y-axis direction of the second panel 101. The first joint 116 is configured to connect the second panel 101 and the third panel 102. The first joint 116 may include a triangular cross-sectional shape.

[0120] Both end portions of the first joint 116 may be connected to one 1031 of the first panels and the other one 1032 of the first panels, respectively.

[0121] A first surface of three side surfaces of the first joint 116 may be connected to one surface of the third panel 102. A second surface of the first joint 116 may be connected to one surface of the second panel 101. A third surface of the first joint 116 is formed to extend in a diagonal direction to connect respective ends of the first surface and the second surface. The third surface of the first joint 116 may be disposed toward the storage chamber.

[0122] A first coupler 1164 may be provided in the first joint 116. The first coupler 1164 is formed in the plate shape. The first coupler 1164 may extend to protrude in one direction from the second surface of the first joint 116. The first coupler 1164 includes a coupling hole.

[0123] The first coupler 1164 is disposed to cover an end portion of the first bolt plate 1091. The first coupler 1164 and the end portion of the first bolt plate 1091 are disposed to overlap in the X-axis direction.

[0124] A bolt 1095 disposed at the end portion of the first bolt plate 1091 may be coupled to the first coupler 1164 by passing through the coupling hole of the first coupler 1164. A coupler such as a nut, etc., is coupled to the bolt 1095 to couple the first joint 116 to the first plate 1081 of the second panel 101.

[0125] However, instead of the bolt plate 109 including the bolt 1095, a nut plate including a nut part may be installed on the first plate 1081 of the second panel 101. In this case, a coupler such as a bolt, etc., is coupled to the nut part, so that the first joint 116 may also be coupled to the first plate 1081 of the second panel 101.

[0126] The first storage chamber joint 115 may include a second joint 117 disposed at a corner portion where the second panel 101 and the first panels 1031 and 1032 are connected.

[0127] The second joint 117 is formed to extend in the Z-axis direction. The second joint 117 extends longer in the Z-axis direction than a length of the first bolt plate 1091. The second joint 117 is disposed at the end portion of the second panel 101. The second joint 117 includes substantially the same configuration as the first joint in that the second joint 117 includes the triangular cross-sectional shape, and thus redundant description will be omitted.

[0128] A first surface of the second joint 117 may be connected to one surface of one 1031 of the first panels and / or the other one 1032 of the first panels. A second surface of the second joint 117 is connected to one surface of the second panel 101.

[0131] The bolt 1095 disposed at the end portion of the first bolt plate 1091 may be coupled to the second coupler 118 by passing through the coupling hole of the second coupler 118. The coupler such as the nut, etc., is coupled to the bolt 1095 to couple the second joint 117 to the first plate 1081 of the second panel 101.

[0132] The end portion of the second joint 117 may be connected to one surface of a partition wall 107 (see FIG. 16).

[0133] The 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 to one side (e.g., a leftward direction or rightward direction) from a portion 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.

[0134] The extension rib 114 may extend in a lengthwise direction of the second joint 117. One end of the extension rib 114 may be disposed to be connected to or to overlap with the end portion of the first bolt plate 1091.

[0135] The first coupler 1164 of the first joint 116 may be disposed to overlap and cover the first bolt plate 1091 and the extension rib 114 of the second joint 117. The coupler such as the nut, etc., is coupled to the bolt 1095 to firmly maintain a coupling force of the first joint 116, the second joint 117, and / or the first bolt plate 1091.

[0136] When the first coupler 1164 of the first joint 116, and the first bolt plate 1091 are coupled, the first coupler 1164 presses the extension rib 114 of the second joint 117, thereby obtaining an effect of bringing the second joint 117 into close contact with one surface of the second panel 101 and / or one surface of the first panels 1030 and 1032.

[0137] The extension rib 114 covers one surface of the first bolt plate 1091, thereby minimizing heat leakage through the bolt plate 109.

[0138] The first storage chamber joint 115 may include a third joint 119 disposed at a corner portion where the third panel 102 and the first panels 1031 and 1032 are connected.

[0139] The third joint 119 is formed to extend in an X-axis direction of a first panel 103. The third joint 119 is disposed at each of the end portions of the first panels 1031 and 1032. The second joint 117 includes substantially the same configuration as the first joint 116 in that the second joint 117 includes the triangular cross-sectional shape, and thus redundant description will be omitted.

[0140] A first surface of the third point 119 may be connected to one surface of the first panel 103. A second surface of the third joint 119 is connected to one surface of the third panel 102. A third surface of the third joint 119 extends in the diagonal direction to connect the first surface and the second surface of the third joint 119.

[0141] An end portion of the third joint 119 facing an opposite direction to the door is connected to the end portion of the first joint 116 and the end portion of the second joint 117. A connection part is further provided at the end portion of the third joint 119. The connection part may be formed slantly to be connected facing the third surface of the first joint 116.

The receiving groove 1212 is a fourth panel exhaust port receiving groove for receiving a fourth panel exhaust port 1224. The receiving groove 1212 may be formed to be opened in one direction.

[0148] The fourth panel exhaust port 1224 is received in the receiving groove 1212. Through this, the first joint 121 covers the fourth panel exhaust port 1224 to block a contact between the fourth panel exhaust port 1224 and cold air in the second storage chamber 106, thereby improving heat insulation performance.

[0149] The second surface 1212 of the first joint 121 may be formed to be connected to one surface of the second panel 101. The second surface 1212 of the first joint 121 may form a rear surface of the first joint 121.

[0150] A plurality of holes 1214 and 1216 may be formed to be recessed on the second surface 1212 of the first joint 121. A first hole 1214 of the plurality of holes 1214 and 1216 is an exhaust port receiving hole formed to exhaust air in order to configure the vacuum heat insulator 108 of the second panel 101.

[0151] A third panel exhaust port 1215 is received in the first hole 1214. Through this, the first joint 121 covers the third panel exhaust port 1215 to block a contact between the third panel exhaust port 1215 and the cold air in the second storage chamber 106, thereby improving the heat insulation performance.

[0152] A second hole 1216 of the plurality of holes 1214 and 1216 may be a hole for forming a suction line heat exchanger (hereinafter referred to as SLHX) withdrawal part. The suction line as a refrigerant pipe connected between the evaporator 148 and the compressor suctions a refrigerant passing through the evaporator 148 into the compressor. The SLHX is configured by welding a capillary pipe to an outer circumferential surface of the suction line through soldering, etc. Through this, the SLHX performs heat exchange by connecting the capillary pipe and the suction line to each other at a surface area on a suction side of the compressor.

[0153] An SLHX withdrawal part 1217 is received in the second hole 1216. Through this, the first joint 121 covers the SLHX withdrawal part 1217 to block a contact between the SLHX withdrawal part 1217 and the cold air in the second storage chamber 106, thereby improving the heat insulation performance.

[0171] A third coupler 124 may be provided at at least one of a first end portion and a second end portion of the second joint 123. The third coupler 124 may be formed to protrude in one direction from the first surface 1231 of the second joint 123. The third coupler 124 is formed in the plate shape. A coupling hole is formed in the third coupler 124. The third coupler 124 may be coupled by the bolt 1095 which protrudes from the end portion of the first bolt plate 1091 located on one side. The bolt 1095 penetrates the coupling hole of the coupler and the nut is coupled to the penetrating bolt 1095, and as a result, the second joint 123 may be coupled to the first plate 1081 which is one surface of the second panel 101.

[0172] The second storage chamber joint 120 may include a third joint 127 disposed at a corner portion where the fourth panel 104 and the first panels 1031 and 1032 are connected.

The second surface is formed to be connected to one 1031 of the first panels and / or the other one 1032 of the first panels. The third surface may extend in one direction from the first surface. The third surface is disposed to face the second surface. A one-direction height of the third surface may be smaller than a one-direction height of the second surface.

[0176] The fourth surface is formed to be inclined toward one 1031 of the first panels and / or the other one 1032 of the first panels from the third surface.

[0177] A plurality of side panel exhaust ports 1274 may be formed at an end portion of one surface of one 1031 of the first panels and / or the other one 1032 of the first panels. A side 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 covers the side panel exhaust port 1274 to block a contact between the side panel exhaust port 1274 and the cold air in the second storage chamber 106, thereby improving the heat insulation performance.

[0178] The second storage chamber joint 120 may be assembled in the order of the first joint 121 to the third joint 127. However, the present disclosure is not limited to this order.

[0179] A coupling protrusion 128 may be formed to protrude in one direction (e.g., forward) from the couplers 1164, 118, and 124. The coupling protrusion 128 may be formed to protrude in a circular shape to surround a coupling hole. A wall of the coupling protrusion 128 may be formed in a polygonal shape such as a hexagon. Accordingly, when the coupler such as the nut, etc., is coupled to the bolt 1095 after the bolt 1095 penetrates the coupling hole, the wall of the coupling protrusion 128 engages with a wall of the nut while enclosing the wall of the nut, thereby preventing loosening of the nut.

[0180] The coupling protrusion 128 may reinforce rigidity of the coupler when a plate thickness of the coupler is thin.

[0181] A separation space may be formed between an outer wall of the coupling protrusion 128 and the third surface of the second joint 123. A reason for keeping the separation space 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.

[0182] The coupling protrusion 128 may not only be applied to the first and second joints 121 and 123 of the second storage chamber joint 120, but may also be applied to the first storage chamber joint 115 in the same or similar manner.

[0183] A third plate 143 or 129 may be attached to the first plate 1081. The third plate 143 or 129 may reinforce the rigidity of the first plate 1081.

[0184] The third plate 129 may be disposed to overlap with the bolt plate 109 in the X-axis direction. Through this, the rigidity of the vacuum heat insulator 108 may be reinforced when coupling the bolt of the bolt plate 109.

[0185] Since other components are the same as or similar to the embodiments of FIGS. 1 to 13 described above, redundant description will be omitted.

[0411] Since other components are the same as or similar to the embodiments of FIGS. 1 to 26 described above, redundant description will be omitted.

[0412] FIG. 32 is a conceptual view illustrating a structure in which a component coupler brings a second storage chamber joint 520 into close contact with one surface of the main body 100 according to still yet another embodiment of the present disclosure.

[0413] The embodiment is different from the embodiments in FIGS. 1 to 26 in that a contact frame 530 closely couples the second storage chamber joint 520 and a heat-insulating block 522 to one surface of the second storage chamber 106.

[0414] However, the embodiment is similar to the embodiments in FIGS. 34 to 38 described above in that the second storage chamber point 520 and the heat-insulating block 522 are closely contacted using at least two contact frames 530 disposed to be spaced apart from each other in the X-axis direction, but is different from the embodiments in FIGS. 34 to 38 described above in a partial structure of the contact frame 530.

[0415] The component coupler includes the contact frame 530. The contact frame 530 may be coupled to the heat-insulating block 522. The contact frame 530 may be formed in a plate shape. The contact frame 530 may extend in a Z-axis direction of the heat-insulating block 522 between one surface of the partition wall and a fourth block part 540. At least two contact frames 530 may be disposed to be spaced apart from each other in an X-axis direction of the heat-insulating block 522.

[0416] A coupler 531 may be provided in at least one of a first end portion and a second end portion of the contact frame 530. The coupler 531 may extend in a Y-axis direction from at least one of the first end portion and the second end portion of the contact frame 530. A coupling hole may be formed in the coupler 531. The coupler such as a screw, etc., may be coupled to the partition wall and the fourth block part 540 through the coupling hole.

[0417] Through this, an end portion of the contact frame 530 may be coupled to the partition wall. The end portion of the contact frame 530 may be coupled to the fourth block part 540.

[0418] A frame coupling groove may be formed on one surface of the heat-insulating block 522. The frame coupling groove may be formed concavely to correspond to the contact frame 530. The frame coupling groove may extend in the Z-axis direction of the heat-insulating block 522. The contact frame 530 may be inserted and coupled into the frame coupling groove.

[0419] Through this, the frame coupling groove may limit movement of the contact frame 530 in the X-axis direction. When the contact frame 530 is inserted and coupled into the frame coupling groove, one surface of the contact frame 530 and one surface of the heat-insulating block 520 may be coplanar with each other.

[0420] The contact frame 530 may bring at least one of the heat-insulating block 522 and the second storage chamber joint 520 into close contact with one surface of one 1031 of the first panels and / or the other one 1032 of the first panels.

[0421] The contact frame 530 may limit movement of the heat-insulating block 522 and / or the second storage chamber joint 520 in the X-axis direction.

[0422] The contact frame 530 may be coupled to the heat-insulating block 522 by the coupler such as a screw, etc. The embodiment shows that the contact frame 530 located at a portion where the second joint 521 of the second storage chamber joint 520 and the heat-insulating block 522 are connected is coupled by the coupler.

[0423] A connection frame 533 may be disposed between at least two contact frames 530. The connection frame 533 may extend in the X-axis direction along the heat-insulating block 522. The connection frame 533 may connect at least two contact frames 530.

[0424] The second storage chamber drawer guide 534 may be coupled to one surface of the heat-insulating block 522. The second storage chamber drawer guide 534 may extend in the X-axis direction along the heat-insulating block 522. At least two second storage chamber drawer guides 534 may be disposed to be spaced apart from each other in the Z-axis direction of the heat-insulating block 522.

[0425] The drawer guide 534 may include a guide protrusion 5341. The guide protrusion 5341 may extend in a lengthwise direction of the drawer guide 534. A receiver 5342 may be formed between at least two guide protrusions 5341. An insertion protrusion may be formed to protrude from a side surface of the drawer. The insertion protrusion of the drawer may be inserted into and coupled to the receiver 5342 when the drawer is withdrawn and introduced.

[0426] The second storage chamber drawer guide 534 may cross the contact frame 530 in one direction (e.g., perpendicular to each other). The second storage chamber drawer guide 534 may be disposed to cover the contact frame 530. Through this, the second storage chamber drawer guide 534 may limit movement of the contact frame 530 in the Y-axis direction.

[0427] The second storage chamber drawer guide 534 may be coupled to the heat-insulating block 522 by the coupler such as a screw, etc. A coupling hole 428 may be formed in at least one of a first end portion and a second end portion of the second storage chamber drawer guide 534. As the coupler is coupled by penetrating the coupling hole 428 of the drawer guide 534 and the coupling hole 428 of the heat-insulating block 522, the drawer guide 534 and the heat-insulating block 522 may be coupled to each other.

[0428] As the contact frame closely couples the heat-insulating block 522 to one surface of one 1031 of the first panels and / or the other one 1032 of the first panels, the heat-insulating block 522 and the second storage chamber drawer guide 534 may be coupled to one 1031 of the first panels and / or the other one 1032 of the first panels.

[0429] The second storage chamber drawer guide 534 may be disposed to be spaced apart from at least one of one side of the third heat-insulating block 523 of the second storage chamber 106, the other side of the third heat-insulating block 523 of the second storage chamber 106, and the first block part 242 of the fourth heat-insulating block 539 of the second storage chamber 106 at a predetermined interval in the Z-axis direction. Through this, at least one of the third heat-insulating block 523 and the fourth heat-insulating block 539 may be closely coupled to one 1031 of the first panels and / or the other one 1032 of the first panels.

[0430] Therefore, the contact frame 530 extending in the Z-axis direction and the second storage chamber drawer guide 534 extending in the X-axis direction may closely couple the third heat-insulating block 523 and the fourth heat-insulating block 539 of the second storage chamber 106 to one surface of one 1031 of the first panels and / or the other one 1032 of the first panels.

[0431] Since other components are the same as or similar to the embodiments of FIGS. 1 to 32 described above, redundant description will be omitted.

[0432] FIG. 33 is a conceptual view illustrating before and after a partition wall 620 is coupled to one surface of the heat-insulating block 522 of the second storage chamber 106 according to still yet another embodiment of the present disclosure.

[0433] The heat-insulating block 522 located in the second storage chamber 106 may further extend in one direction to enclose one surface and the other surface of the partition wall 620.

[0434] An insertion groove 624 into which an end portion of the partition wall 620 is inserted and coupled may be formed on one surface of an end portion of the heat-insulating block 522.

[0435] The insertion groove 624 may extend in the X-axis direction of the heat-insulating block 522. A Z-axis direction width of the insertion groove 624 may be formed to be narrowed from a first end portion to a second end portion of the third heat-insulating block 523.

[0436] A side surface guide part 621 may be formed to protrude on one surface of the partition wall 620 in the Y-axis direction. The side surface guide part 621 may be formed to correspond to the insertion groove 624. A Z-axis direction width of the side surface guide part 621 may be formed to be narrowed from a first end portion to a second end portion of the heat-insulating block 522.

[0437] Through this, the side surface guide part 621 of the partition wall 620 may be easily inserted and coupled into the insertion groove 624.

[0438] When the partition wall 620 is inserted and coupled between at least two heat-insulating blocks 522 located on at least one of one surface of one 1031 of the first panels and one surface of the other one 1032 of the first panels, the heat-insulating block 522 may be closely coupled to one 1031 of the first panels and / or the other one 1032 of the first panels.

[0439] A duct connection part 622 may be formed to penetrate the end portion of the partition wall 620 in the Z-axis direction. The duct connection part 622 is a hole forming a flow path for communicating an evaporator receiver 5342 or 424 of the second storage chamber 106 and the multi-duct of the first storage chamber 105. The duct connection part 622 may be disposed at a center of the end portion of the partition wall 620.

[0440] A return duct forming part 623 may be formed at a portion (e.g., left and / or right end of a rear end) of the partition wall 620. The return duct forming part 623 may be formed to be recessed in one direction (e.g., forward) at a portion (e.g., left and / or right end of the rear end) of the partition wall 620. The return duct forming part 623 forms a flow path connecting the first storage chamber 105 and the second storage chamber 106 so that the cold air in the first storage chamber 105 circulates to the second storage chamber 106.

[0441] Since other components are the same as or similar to the embodiments of FIGS. 1 to 32 described above, redundant description will be omitted.

[0442] Therefore, according to the present disclosure, at least two panels 101, 102, 103, and 104 including vacuum heat insulators are assembled to manufacture the main body 100 of the refrigerator, and the joint 110 including the insulator-insulating material 112 is disposed at corner portions where the plurality of vacuum heat insulator panels are connected to reinforce heat insulation of the corner portions.

[0443] Second, the bolt plate 109 may be installed on one surface of the at least two panels 101, 102, 103, and 104. The bolt 1095 is formed to protrude from the bolt plate 109. The joint 110 is provided with the couplers 1164, 118, and 124 including coupling holes formed therein. The bolt 1095 penetrates the coupling hole 428 of the coupler, and as the nut is coupled to the bolt 3281, the joint 110 may be easily coupled to one surface of the main body 100 such as the second panel 101 by the bolt plate.

[0444] Third, the heat-insulating blocks 230, 323, 427, and 439 may be integrally formed with the joints 220, 320, and 420. The heat-insulating blocks 230, 323, 427, and 439 may extend a heat insulation area of the joints 220, 320, and 420. The heat-insulating blocks 230, 323, 427, and 439 may be disposed by utilizing a space that does not change the internal volume of the refrigerator.

[0445] Fourth, the heat-insulating block 230 may be coupled by the bolt plate 229 installed on one surface of the main body 100. The coupling hole is formed in the heat-insulating block 230. The bolt 2291 of the bolt plate 229 penetrates the coupling hole of the heat-insulating block 230, and as the nut is coupled to the bolt 2291, the heat-insulating block 230 may be easily coupled to one surface of the main body 100 such as the second panel 101 and one 1031 of the first panels and / or the other one 1032 of the first panels by the bolt plate 229.

[0446] Fifth, the contact frames 330, 430, and 530 may be coupled to one surface of the joints 320, 420, and 520 or the heat-insulating block 522 in which the joint 320 is integrally formed. The coupling holes 428 are formed in the contact frames 330, 430, and 530. The contact frames 330, 430, and 530 may be coupled to one surface of the main body 100 by the bolt plate 328 or may be coupled without the bolt plate. As the couplers such as screws penetrate and are coupled to the coupling holes of the heat-insulating blocks 427, 439, and 522 and the coupling holes 428 of the contact frames 430 and 530, the contact frames 430 and 530 may closely couple the heat-insulating blocks 427, 439, and 522 to one surface of the main body 100 without the bolt plate. The extension ribs 114 and 125 may extend in the lengthwise direction of the joints 320, 420, and 520. The contact frames 330, 430, and 530 may closely couple the joint 320 to one surface of the main body 100 by pressing the extension ribs 114 and 125 or directly pressing the joint 320.

[0447] Sixth, components disposed inside the main body 100, for example, the shelf 130, a drawer, etc., may be provided with a separate first component coupler 131 to be coupled to one surface of the main body 100. The first component coupler 131 or the drawer guides 1411 and 1421 including the penetration hole 1324 may be easily coupled to one surface of the main body 100 by the bolt plate 109. The bolt 1095 of the bolt plate 109 penetrates the coupling hole of the first component coupler 131, and as the nut is coupled to the bolt 1095, the shelf 130 may be easily coupled to one surface of the main body 100. The bolts 1091 and 2291 of the bolt plates 109 and 229 penetrate the coupling holes of the drawer guides 1411, 1421, 227, and 228, and as the nuts are coupled to the bolts 1091 and 2291, the drawer guides 1411, 1421, 227, and 228 may be easily coupled to one surface of the main body 100.

[0448] Seventh, the end portions of the contact frames 430 and 530 may be coupled to the partition wall 620. The end portions of the contact frames 430 and 530 may be coupled to the fourth block parts 440 and 540 which are the heat-insulating blocks 439 and 522 of the fourth panel 104. As the drawer guides 429 and 534 are coupled to the heat-insulating blocks 439 and 522 by the couplers such as screws, the contact frame 530 may easily closely couple at least one of the heat-insulating blocks 439 and 522 and the drawer guides 429 and 534 to one surface of the first panel and / or the second panel 103.

[0449] Eighth, the contact frames 430 and 530 are coupled to one surface of the heat-insulating blocks 439 and 522 formed integrally with the second storage chamber joint 520. Through this, the contact frames 430 and 530 may easily couple the second storage chamber joint 520 or the heat-insulating blocks 439 and 522 to one surface of the main body 100. The contact frames 430 and 530 do not require the bolt plate, thereby not only blocking heat leakage through the corners but also being advantageous for improving heat insulation performance.[DETAILED DESCRIPTION OF MAIN ELEMENTS]
