Description

Insulator

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

[0002] A refrigerator is configured to include a refrigerator body having a storage compartment for storing food inside, and a door for opening and closing the storage compartment. The refrigerator body is provided with a cold air supply device capable of supplying cold air to the storage compartment. The refrigerator body has an outer case forming an outer appearance, an inner case spaced apart from one side of the outer case, and an insulating part filled between the outer case and the inner case. In conventional refrigerators, there is a problem in that the insulating part forming the wall of the storage compartment of the refrigerator is relatively thick, so that the storage compartment becomes relatively small compared to the size of the exterior.

[0003] Accordingly, the purpose of the present invention is to provide a refrigerator equipped with a vacuum insulation body capable of reducing the thickness of an insulation wall forming a storage room.

[0004] Another object of the present invention is to provide a refrigerator equipped with a vacuum insulation material capable of suppressing cold air loss in the boundary area of ​​adjacent insulating walls forming a storage room.

[0005] Another object of the present invention is to provide a refrigerator having a vacuum insulator capable of suppressing interference between internal components of a storage compartment.

[0006] Another object of the present invention is to provide a refrigerator having a vacuum insulator capable of suppressing interference between a joint insulating the boundary of an insulating wall forming a storage room and a shelf support frame.

[0007] The insulator of the present invention may be provided as at least one insulator. For example, the insulator of the present invention may provide a first wall extending in one direction; and a second wall extending in a direction different from the one direction. As another example, the insulator of the present invention may include a first insulator and a second insulator. The second insulator may be provided as a separate component separated from the first insulator. The second insulator may be connected to the first insulator by a connecting member. In the present invention, the connecting member may be defined as a joint. The second insulator may include a portion extending in the same direction as the first insulator. Each of the first, second, third, and fourth panels may be provided in plurality. The panels may be insulators or vacuum insulators. The first panel may include one of the first panels forming one of the first surfaces of the refrigerator, and the other of the first panels forming the other 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 compartment 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.

[0008] The refrigerator of the present invention may include at least one panel. A plurality of such panels may be connected by joints. The present invention may include a first panel forming a first side (e.g., a side) of the refrigerator. Optionally, the present invention may include a second panel forming a second side (e.g., a rear) of the refrigerator. Optionally, the present invention may include a third panel forming a third side (e.g., a top) of the refrigerator. Optionally, the present invention may include a fourth panel forming a fourth side (e.g., a bottom) of the refrigerator. Each of the first, second, third, and fourth panels may be provided in multiples. The panels may be insulators or vacuum insulators.

[0009] Specifically, by providing a joint formed by a plurality of vacuum insulators forming a corner of the storage room and an insulating member arranged to block the corner, the thickness of the insulating wall of the storage room can be significantly reduced.

[0010] By suppressing the formation of heat bridges at the corners of the storage room, the increase in cold air loss in the storage room due to the formation of the heat bridges can be significantly suppressed.

[0011] The present invention may include a main body having a storage compartment therein, a first panel provided on both sides of the storage compartment, a second panel provided in the storage compartment, and / or a third panel provided on a third side of the storage compartment. A shelf may be provided inside the storage compartment. The storage compartment may be formed of an insulating material, and a joint may be provided at a corner formed by at least two or more of the first, second, and third panels. A shelf support frame may be provided that is connected to the second panel or supports the shelf so as to be spaced apart from the corner. At least one of the first panel, the second panel, and the third panel may be provided with a first plate arranged toward the storage compartment; a second plate spaced apart from the first plate and forming a vacuum space with the first plate; and a vacuum space provided between the first plate and the second plate. This can prevent heat bridges from forming at the corners of the storage compartment, thereby increasing cold air loss. Since the insulation walls of the storage compartment are formed of vacuum insulation, the thickness of the insulation walls can be significantly reduced. With this configuration, the capacity of the storage compartment can be significantly increased, even with the same external dimensions.

[0012] The joint may include a first insulation portion provided on at least one of both sides of the second panel. The joint may include a second insulation portion provided to be connected to the first panel or bent from the first insulation portion. The shelf support frame may be spaced apart from the second panel. The first insulation portion is configured to be provided between the shelf support frame and the second panel. As a result, cold air leakage through the corners (e.g., left corner and right corner) of the second panel can be suppressed. By suppressing direct connection between the shelf support frame and the second panel, cold air leakage due to the connection between the shelf support frame and the second panel can be suppressed. The length of the first insulation portion is formed longer than the length of the second insulation portion. As a result, connection between the surface of the second panel and the air of the storage room can be suppressed.

[0013] Optionally, the first region (e.g. rear region) of the shelf is provided with a protruding engagement projection.

[0014] The above-mentioned coupling protrusion has a first protrusion and / or a second protrusion that are spaced apart. The first protrusion is configured to have a bent portion that is bent downward with respect to the protruding direction. The above-mentioned shelf support frame may include an insertion surface having an insertion hole into which the above-mentioned coupling protrusion is inserted. The above-mentioned shelf support frame may include a connection surface provided on the insertion surface and connected to the joint. The above-mentioned shelf support frame may include a connection surface connecting the insertion surface and the connection surface. The connection surface is bent in a direction away from the first panel from the connection surface. As a result, the connection surface of the shelf support frame is spaced apart from the edge, so that cold air leakage through the connection surface of the shelf support frame can be suppressed. The length between the first panel and the insertion surface is formed longer than the length between the first panel and the shelf. As a result, the storage capacity of the shelf can be increased, and cold air leakage through the shelf support frame can be suppressed.

[0015] Optionally, the joint is configured to further include a connecting insulation portion connecting the first insulation portion. As a result, connection between the air in the storage compartment and the second panel can be suppressed. A multi-duct receiving space is formed in the first insulation portion and / or the connecting insulation portion of the joint. As a result, the multi-duct can be arranged to be spaced apart from the edge of the second panel. With this configuration, cold air leakage of the multi-duct can be suppressed by spaced apart from the edge of the second panel.

[0016] Optionally, the joint comprises a third insulation portion bent from the connecting insulation portion so as to be connectable to the third panel. As a result, cold air leakage through the edges of the second panel and the third panel can be suppressed.

[0017] Optionally, the joint support frame is configured to be connected to the joint and to support the joint while being pressed toward the second panel. This reduces the number of separate high-intensity component support members required to support the joint to the second panel.

[0018] The above joint support frame is formed integrally with the shelf support frame. This reduces the number of separate high-density component support members required for joint support of the joint support frame and the shelf support frame.

[0019] Optionally, the joint support frame may include a first pressing surface for pressing the joint. The joint support frame may have a second pressing surface that is bent at one side of the first pressing surface. The first pressing surface may be connected to the first insulation portion and / or the connecting insulation portion. The second pressing surface is configured to be connected to the second insulation portion. As a result, the first insulation portion and / or the connecting insulation portion of the joint may be brought into close contact with the second panel. The second insulation portion of the joint may be prevented from being separated from the first panel. The first pressing surface is disposed to face the insertion surface of the shelf support frame, and the second pressing surface is disposed to face the connecting surface of the shelf support frame. As a result, the joint support frame and the shelf support frame may be joined to form a rectangular cross-section. As a result, the installation space of the joint support frame and / or the shelf support frame may be reduced.

[0020] Optionally, the third panel comprises a support bracket that supports a portion (e.g., an upper portion) of the joint support frame. The joint support frame can be supported by the support bracket while in close contact with the joint. This reduces the number of separate internal component support members for supporting the joint support frame. The joint support frame is configured such that a portion thereof is connected to the partition wall.

[0021] Optionally, the joint may include a first connecting portion extending in a first direction and a second connecting portion extending in a second direction. The joint may include a connecting portion connecting the first connecting portion and / or the second connecting portion. The joint may include a filling portion filled within the first connecting portion, the second connecting portion and / or the connecting portion. The first connecting portion may be connected to the second panel. The second connecting portion may be arranged to be connected to the first panel. The shelf support frame is provided between the first connecting portions. As a result, an edge forming a boundary between the second panel and the first panel may be blocked by the joint, thereby suppressing cold air leakage through the edge. Since the shelf support frame is arranged to be spaced apart from the edge of the second panel and the first panel, cold air leakage due to the proximity of the shelf support frame and the edge may be suppressed.

[0022] Optionally, the shelf support frame may include an insertion surface having an insertion hole into which the coupling protrusion is inserted. The shelf support frame may include a surface that is bent on at least one of the two sides of the insertion surface. The shelf support frame is configured to include a connecting surface that is bent on at least one of the two sides and connected to the second panel. As a result, the load of the shelf can be distributed and supported on the second panel.

[0023] Optionally, a high-intensity component support member for supporting the shelf support frame is provided between the second panel and the shelf support frame. As a result, the shelf support frame can be integrally connected to the second panel. The high-intensity component support member can include a plate connected to the second panel; and / or a bolt protruding from the plate. A bolt hole is formed through a connecting surface of the shelf support frame so that the bolt can be inserted. The bolt protrudes through the bolt hole, and a nut can be screwed onto the bolt. The plate of the high-intensity component support member can be bonded to the first plate of the second panel by an adhesive. The plate of the high-intensity component support member can be welded to the first plate of the second panel. As a result, the assembly and connection of the shelf support frame can be smoothly performed.

[0024] Optionally, the support includes a bar spaced apart between the first plate and the second plate, and the second panel is configured to have a heat transfer suppression section in which the density of the bar is formed lower than that of the surrounding area, corresponding to one area of ​​the shelf support frame and / or one area of ​​the high-density internal component support member. As a result, leakage of cold air inside the storage room to the outside of the storage room through the shelf support frame, the connection point of the first plate of the second panel connected to the shelf support frame, the bar directly connected to the connection point, and / or the bar adjacent to the connection point can be suppressed. The second panel is configured to have a strength reinforcement section in which the density of the bar is formed higher than that of the surrounding area, in one area of ​​the shelf support frame. As a result, damage or deformation of the second panel due to the load of the shelf can be suppressed. The second panel may include a first bar having a first thickness and a second bar having a second thickness that is thicker than the first thickness. The second panel is formed such that the second bar is arranged in one area of ​​the shelf support frame and the first bar is arranged in an area spaced apart from one area of ​​the shelf support frame. As a result, damage or deformation of the second panel due to the load of the shelf can be suppressed.

[0025] Optionally, the shelf support frame may be provided with at least one insertion hole through which the coupling protrusion can be inserted and which is spaced apart from each other. A multi-duct through which cold air is discharged may be provided between the shelf support frames. A multi-duct cover may be provided on one side of the multi-duct to block at least a portion of the multi-duct, the shelf support frame, and the joint. The multi-duct cover has a penetration portion through which the insertion hole can be exposed. As a result, the first plate, which is a surface of the second panel, is blocked, thereby suppressing direct connection between the air of the storage room and the second panel. The height of the shelf may be smoothly adjusted.

[0026] As described above, according to one embodiment of the present invention, a joint made of an insulating material is provided at the edge forming the boundary between the first panel and the second panel, thereby suppressing cold air leakage through the edge of the first panel and the second panel.

[0027] Since the first panel, the second panel, and / or the third panel are composed of a vacuum insulator, the internal storage capacity can be increased without increasing the external size of the refrigerator body.

[0028] By providing a shelf support frame spaced apart from the edge forming the boundary between the first panel and the second panel, cold air leakage through the shelf support frame can be suppressed.

[0029] The above joint may include a first insulation portion provided on both sides of the second panel and / or a second insulation portion bent from the first insulation portion so as to be connected to the first panel. The shelf support frame may be spaced apart from the second panel, or the first insulation portion may be provided between the shelf support frame and the second panel, thereby suppressing direct connection between the shelf support frame and the second panel. Cold air leakage through the shelf support frame may be suppressed.

[0030] The length of the first insulation part is formed to be longer than the length of the second insulation part, so that direct connection between the second panel and the internal air of the storage room can be suppressed.

[0031] The above shelf support frame may have an insertion surface having an insertion hole, a connection surface provided on the insertion surface and connected to the joint, and / or a connection surface connecting the insertion surface and the connection surface. The connection surface is configured to be bent in a direction away from the first panel, thereby suppressing cold air leakage through the connection surface of the shelf support frame.

[0032] The length between the first panel and the insertion surface is formed to be longer than the length between the first panel and the shelf, so that the storage capacity of the shelf can be increased, and also, cold air leakage through the shelf support frame can be suppressed.

[0033] The above joint is configured by further including a connecting insulation part connecting the first insulation part, so that connection between the surface of the second panel and the internal air of the storage room can be suppressed.

[0034] The above joint is configured to include a third insulation portion bent from the connecting insulation portion so as to be connectable to the third panel, thereby suppressing cold air leakage through the corner forming the boundary between the second panel and the third panel.

[0035] By including a joint support frame that is connected to the above joint and supports the joint while being pressed toward the second panel, the number of separate high-intensity component support members to be installed to support the joint can be reduced.

[0036] Since the above joint support frame is formed integrally with the shelf support frame, the number of separate high-intensity component support members for supporting the joint support frame and / or the shelf support frame can be reduced.

[0037] The joint support frame may have a first pressure surface and / or a second pressure surface. The first pressure surface may be connected to the first insulation portion and / or the connecting insulation portion. The second pressure surface may be connected to the second insulation portion. Through this, the joint may be brought into close contact with the second panel and / or the first panel.

[0038] The first pressure surface may be positioned opposite the insertion surface of the shelf support frame. The second pressure surface may be positioned opposite the connection surface of the shelf support frame. This allows the installation space of the shelf support frame and the joint support frame to be reduced.

[0039] By providing a support bracket that supports a part (e.g., the upper part) of the joint support frame on the third panel, the number of separate internal component support members for supporting the joint support frame can be reduced.

[0040] By attaching a portion (e.g., the lower portion) of the above joint support frame to the partition wall, the number of separate internal component support members for supporting the above joint support frame can be reduced.

[0041] The joint may include a first connecting portion, a second connecting portion, a connecting portion connecting the first connecting portion and the second connecting portion, and / or a filling portion filling at least one of the first connecting portion, the second connecting portion, and the interior of the connecting portion. The joint may be arranged such that the first connecting portion is connected to the second panel and / or the second connecting portion is connected to the first panel. The shelf support frame may be provided between the first connecting portions, thereby suppressing cold air leakage through the corner forming the boundary between the first panel and the second panel.

[0042] The shelf support frame has an insertion surface having an insertion hole into which a connecting projection of the shelf is inserted, a side surface bent at one side (e.g., both sides) of the insertion surface, and / or a connecting surface bent at the side surface and connected to the second panel, so that the load of the shelf can be supported in a distributed manner.

[0043] A high internal component support member is provided between the second panel and the shelf support frame, so that the shelf support frame can be supported by being integrally connected to the second panel.

[0044] The above-mentioned internal component support member may be provided with a plate that is coupled to the second panel and / or a bolt protruding from the plate. The connecting surface of the shelf support frame is provided with a through-hole through which the bolt can be inserted, thereby enabling smooth coupling and joining of the shelf support frame.

[0045] A heat transfer suppression section in which the density of the bar is formed lower than that of the surrounding area is provided in the first area (e.g., rear area) of the shelf support frame of the second panel and / or the first area (e.g., rear area) of the high-intensity component support member, so that cold air leakage through the bar can be suppressed.

[0046] By providing a high-density reinforcing section of the bar in the first region (e.g., rear region) of the shelf support frame of the second panel and / or the first region (e.g., rear region) of the high-inner component support member, damage and / or deformation of the second panel due to the load of the shelf can be suppressed.

[0047] The second panel has first and second bars having different thicknesses, and the second bar having a thicker thickness is provided in the first area (e.g., rear area) of the shelf support frame and / or the first area (e.g., rear area) of the high-intensity component support member, so that damage and / or deformation of the second panel due to the load of the shelf can be suppressed.

[0048] A multi-duct for discharging cold air may be provided between the shelf support frames. A multi-duct cover may be provided on one side of the multi-duct to block the multi-duct, the shelf support frame, and / or the joint. The multi-duct cover may be provided with a penetration portion through which the insertion hole can be exposed, thereby suppressing connection between the second panel and the air in the storage room, and facilitating position adjustment of the shelf.

As shown in Figs. 5 to 8, the refrigerator of the present embodiment includes a refrigerator body (100), a shelf (140), a joint (150), and a shelf support frame (170).

[0119] The above refrigerator body (100) forms the exterior of the refrigerator.

[0129] The interior of the refrigerator body (100) may be provided with a partition wall (105) that partitions the storage room (110) in one direction (e.g., up and down).

[0130] The above partition wall (105) is implemented in a rectangular parallelepiped shape with a relatively thin thickness.

[0131] The above partition wall (105) may be configured to include an insulating material.

[0132] By this, heat transfer between the internal space (first storage room (1101), second storage room (1102)) of the storage room (110) partitioned in one direction (e.g., up and down) can be suppressed.

[0133] The above storage room (110) may include, for example, a second storage room (1102) and / or a first storage room (1101).

[0134] The first storage room (1101) and the second storage room (1102) can be partitioned by the partition wall (105).

[0135] A cold air supply path (1051) may be provided in the above partition wall (105).

[0136] The above-mentioned cold air supply path (1051) may be formed by penetrating, for example, a portion of the partition wall (105) (e.g., the rear center portion).

[0144] Meanwhile, the refrigerator body (100) has at least two panels (101, 102, 103, 104) forming the storage compartment (110).

[0145] The above at least two panels (101, 102, 103, 104) may be configured to include, for example, a vacuum insulator (130).

[0146] Specifically, the panels (101, 102, 103, 104) are configured to include, for example, a first panel (101) disposed on both sides of the storage room (110), a second panel (102) disposed in the storage room (110), a third panel (103) disposed on one side of the storage room (110), and / or a fourth panel (104) disposed on the other side of the storage room (110).

[0147] In this embodiment, the first panel (101), the second panel (102) and / or the third panel (103) may be formed of a vacuum insulator (130).

[0148] By this, the thickness of the insulating wall forming the storage compartment (110) of the refrigerator body (100) can be significantly reduced.

[0149] According to this configuration, the storage capacity of the storage compartment (110) can be significantly increased without increasing the external size of the refrigerator body (100).

[0153] The above first plate (1301) may be configured to have a thinner thickness than, for example, the above second plate (1302).

[0154] The first plate (1301) may be configured to have, for example, a folded portion (13011) in which the edge is first folded toward the second plate (1302) and secondarily folded so as to be surface-connected with the second plate (1302). A sealing portion (13012) that is sealingly connected to the second plate (1302) may be formed on one side of the folded portion (13011).

[0155] A shelf (140) may be provided inside the first storage room (1101).

[0157] The above shelf (140) can be placed at a preset distance from the second panel (102) of the first storage room (1101).

[0158] A joint (150) and / or a multi-duct (160) to be described later may be provided between the second panel (102) and the shelf (140).

[0159] The above shelf (140) can be placed at a preset distance from the first panel (101) along one direction of the first storage room (1101).

[0160] The above shelf (140) may be formed, for example, to be spaced inward by about 7 mm from the first panel (101) provided on both sides of the storage room (110).

[0161] By this, unnecessary connection between the shelf (140) and the first panel (101) can be suppressed.

[0162] , the air of the first storage room (1101) can move through the gap between the two ends of the shelf (140) and the first panel (101).

[0163] According to this configuration, the occurrence of local temperature deviation inside the first storage room (1101) can be suppressed.

[0164] The above shelf (140) may be implemented as a plurality of shelves spaced apart from each other, for example.

[0165] The first storage room (1101) is provided with a shelf support frame (170) that supports the shelf (140).

[0166] The above shelf support frame (170) may be provided, for example, in the first area (e.g., rear area) of the storage room (110) (first storage room (1101)).

[0167] The above shelf support frame (170) may be provided, for example, between the second panel (102) and the shelf (140).

[0168] Meanwhile, in the refrigerator of the present embodiment, the first panel (101) and the second panel (102) are arranged at a certain angle (e.g., a right angle) to each other and are integrally connected to each other.

[0169] Here, the first plate (1301) of the first panel (101) and / or the first plate (1301) of the second panel (102) may be provided with a bending portion (13011) that is bent toward the second plate (1302) and is connected to the surface. One side of the bending portion (13011) may be disposed in the storage room (110) and / or the other side may be disposed outside the storage room (110). Through this, the bending portion (13011) may form a heat transfer path (heat bridge) between the inside and the outside of the storage room (110).

[0170] In this embodiment, a joint (150) formed of an insulating material is provided at each corner forming a boundary between the first panel (101) and the second panel (102).

[0171] By this, cold air leakage through the corners (bent portions (13011)) of the first panel (101) and the second panel (102) that form the heat transfer path between the inside and outside of the storage room (110) can be suppressed.

[0172] The above joint (150) is configured to include, for example, a first insulation part (151) provided on the second panel (102) and / or a second insulation part (152) bent from the first insulation part (151) so as to be connected to the first panel (101).

[0173] Here, the first insulation part (151) and / or the second insulation part (152) may each be implemented in a rectangular shape, for example.

[0174] The above joint (150) is configured to include, for example, a connecting insulation part (154) that connects the first insulation part (151).

[0175] The above joint (150) may be configured to have, for example, a preset thickness.

[0176] In this embodiment, the preset thickness of the joint (150) may be implemented to be about 20 mm, but this is only an example and is not limited thereto.

[0177] The above-mentioned connecting insulation part (154) may be configured to connect, for example, a part of the first insulation part (151).

[0178] The above-mentioned connecting insulation part (154) can be configured to connect the first insulation part (151) horizontally, for example.

[0179] The above connecting insulation part (154) may be provided with a third insulation part (153) to block the corner forming the boundary between the second panel (102) and the third panel (103).

[0180] In this embodiment, the edge forming the boundary between the second panel (102) and the third panel (103) can form a heat transfer path, and the third insulation part (153) can suppress cold air leakage by blocking the edge forming the boundary between the second panel (102) and the third panel (103).

[0181] Here, the length from the second panel (102) to the end of the third insulation part (153) may be configured to be, for example, the same as the length from the second panel (102) to the end of the second insulation part (152).

[0182] In this embodiment, since the connecting insulation part (154) is formed to have a preset width, a rectangular multi-duct receiving space (155) can be formed between the first insulation part (151) and the connecting insulation part (154) spaced apart from each other on both sides of the second panel (102).

[0183] A multi-duct (160) can be accommodated in the above multi-duct accommodation space (155).

[0184] In the present embodiment, the multi-duct (160) may be implemented in a rectangular parallelepiped shape with a substantially thin thickness. A cold air passage may be formed inside the multi-duct (160). A cold air discharge hole may be formed through the surface of the multi-duct (160) to communicate with the cold air passage. At least two cold air discharge holes may be formed spaced apart from each other.

[0185] In this embodiment, the cold air discharge holes may be formed, for example, in two rows along one direction.

[0186] A part (e.g., the lower part) of the multi-duct (160) may be connected to the surface of the partition wall (105) and / or a part (e.g., the upper part) of the multi-duct (160) may be configured to be connected to a part (e.g., the lower part) of the connecting insulation part (154).

[0187] The above multi-duct (160) can be placed in the first storage room (1101).

[0188] The one-way length (e.g., left-right width) of the above multi-duct (160) can be configured to be spaced apart from the first insulation part (151) by a preset distance.

[0189] In this embodiment, the distance between the first insulation parts (151) may be formed to be greater than the one-way length (e.g., left-right width) of the multi-duct (160).

[0190] A spacer (156) may be provided between the first insulation portion (151) and the multi-duct (160). The spacer (156) may be provided on each of both sides of the multi-duct (160). The spacers (156) may be arranged to be spaced apart from each other in one direction (e.g., vertically).

[0191] In this embodiment, the width of the first insulation part (151) can be formed to be larger than the width of the second insulation part (152).

[0192] By this, direct connection between the surface of the second panel (102) and the air of the storage room (110) can be suppressed.

[0193] According to this configuration, cold air leakage through the second panel (102) can be suppressed.

[0194] The above joint (150) is provided with a joint support frame (180) that supports the joint (150) in close contact with the second panel (102) and / or the first panel (101).

As shown in Figs. 9 to 12, the shelf (140) may be configured to include, for example, a panel portion (141) in the shape of a rectangular plate and a support portion (142) that supports the panel portion (141) on one side (e.g., the lower side) of the panel portion (141).

[0196] The above panel portion (141) can be formed, for example, of a transparent rigid member.

[0197] The above panel portion (141) can be formed, for example, of compressed reinforced glass.

[0198] The above panel portion (141) may be configured, for example, with a rectangular plate-shaped body (1411) and / or a detachment prevention portion (1412) protruding from the surface of the body (1411).

[0199] The above-mentioned anti-separation part (1412) may be provided, for example, on one side (e.g., front end) and / or the other side (e.g., rear end) of the body (1411).

[0200] By this, food (or container) placed on the surface of the shelf (140) can be prevented from coming off the shelf (140) (body (1411)).

[0201] The above-mentioned anti-separation member (1412) may be formed of, for example, a synthetic resin member or a rubber member.

[0202] An insertion portion (14121) may be provided on one side of the above-mentioned anti-separation portion (1412) so that one side (one end or rear end) of the panel portion (141) can be inserted.

[0203] The insertion portion (14121) of the above-mentioned anti-separation portion (1412) may be configured in a groove shape that is open on one side.

[0204] The above-mentioned support portion (142) may be configured, for example, by having a pair of frames (1421) spaced apart in one direction on one side (e.g., the lower side) of the panel portion (141).

[0205] The above pair of frames (1421) can be connected to each other by a connecting rod (1422).

[0206] The above connecting rod (1422) may be provided, for example, on one side (e.g., rear end) and / or the other side of the pair of frames (1421).

[0207] By this, the pair of frames (1421) can be supported in parallel with each other.

[0208] Each end of the above frame (1421) may be provided with a protruding projection (14211).

[0209] The detachment prevention part (1412) arranged on the above panel part (141) is provided with a protrusion coupling part (14122) so that the protrusions (14211) can be inserted and coupled respectively.

[0210] The above protrusion joint (14122) may be formed to be open, for example.

[0211] The above support portion (142) and / or the panel portion (141) can be joined together by a joining member.

[0212] One side (e.g., rear end) of the above-mentioned support member (142) (frame) may be provided with a joint member insertion portion (14212) into which the joint member (e.g., screw) can be inserted.

[0213] The above-mentioned connecting member can be screw-connected to the panel part (141) (anti-separation part (1412)) after, for example, the connecting member insertion part (14212) of the support part (142) is inserted.

[0214] By this, the panel portion (141) and / or the support portion (142) can be joined in a second region (e.g., a front region) by the protrusion (14211) and the protrusion-joining portion (14122), or the first region (e.g., a rear region) can be joined integrally by the joining member.

[0215] Meanwhile, the shelf (140) may be provided with a protruding connecting projection (1423).

[0216] In this embodiment, the shelf (140) may be implemented in a cantilever shape in which a load is supported by a coupling protrusion (1423) provided in a first region (e.g., rear region) of the shelf (140).

[0217] The above pair of frames (1421) may be configured, for example, such that the height increases from one side (e.g., one end) to the other side (e.g., the rear end).

[0218] The above-mentioned coupling protrusion (1423) may be formed to be spaced apart from, for example, a portion (e.g., a rear end) of the frame (1421).

[0219] The above-mentioned coupling protrusion (1423) may include, for example, a first coupling protrusion (14231) arranged on one side (e.g., upper side) and / or a second coupling protrusion (14232) arranged spaced apart from one side (e.g., lower side) of the first coupling protrusion (14231).

[0220] The first coupling protrusion (14231) may, for example, have a protruding portion (142311) and / or a hook portion (142312) bent downward from the end of the protrusion (142311). The first coupling protrusion (14231) may be implemented in an inverted “L” shape.

[0221] The above second coupling protrusion (14232) can be formed to protrude.

[0222] The above shelf (140) can be supported by a shelf support frame (170) provided in the storage room (110).

[0223] Fig. 13 is a perspective view of the joint support frame and shelf support frame of Fig. 7, and Fig. 14 is a front view of the joint support frame and shelf support frame of Fig. 13. As shown in Figs. 13 and 14, in the present embodiment, the shelf support frame (170) and the joint support frame (180) may be formed integrally.

[0224] By this, the number of separate high-intensity component support members to be installed for supporting the shelf support frame (170) and the joint support frame (180) can be reduced.

[0225] In this embodiment, the joint support frame (180) may be implemented in an inverted “U” shape, for example, by having a first section (e.g., vertical section) (1801) arranged on both sides of the first storage room (1101) and / or a connecting section (1802) connecting a part (e.g., upper part) of the first section (e.g., vertical section) (1801).

[0227] The above shelf support frame (170) is configured as a pair and can be spaced apart to correspond to a part (e.g., rear end) of a pair of frames (1421) of the shelf (140).

[0228] The above shelf support frame (170) can be configured to be coupled to a portion of a first section (e.g., vertical section) (1801) of the above joint support frame (180).

[0229] The above joint support frame (180) may be configured, for example, with a first pressing surface (181) that presses the joint (150) and / or a second pressing surface (182) that is bent on one side of the first pressing surface (181).

[0230] The above joint support frame (180) can be implemented, for example, in an “L” cross-sectional shape.

[0233] Specifically, the first pressure surface (181) can be connected to the first insulation portion (151) and / or the connecting insulation portion (154) of the joint (150).

[0234] By this, the first insulation portion (151) and / or the connecting insulation portion (154) of the joint (150) can be pressed by the first pressurized surface (181) and brought into close contact with the second panel (102).

[0235] The above second pressure surface (182) can be connected to the second insulation portion (152) of the above joint (150).

[0236] By this, the second insulation part (152) can be prevented from being separated (separated) from the first panel (101).

[0237] A part (e.g., the lower part) of the first pressure surface (181) may be provided with, for example, a bent end (1811) that is bent parallel to the partition wall (105).

[0238] The above joint support frame (180) may be configured at a height such that a part (e.g., the lower part) can be connected to the bottom surface of the first storage room (1101) and / or another part (e.g., the upper part) can be arranged close to the ceiling surface (third panel (103)) of the first storage room (1101).

[0239] The side surface (second pressure surface (182)) of the above joint support frame (180) can be configured to be connected to the second insulation portion (152) of the above joint (150).

[0240] The first section (e.g., vertical section) (1801) of the above joint support frame (180) may be arranged at the corners of the first insulation part (151) and the second insulation part (152) of the above joint (150). The above connection section (1802) may be arranged at the corners of the above connection insulation part (154) and the third insulation part (153).

[0241] Specifically, the first pressure surface (181) of the first section (e.g., vertical section) (1801) may be connected to the first insulation portion (151) and / or the second pressure surface (182) of the first section (e.g., vertical section) (1801) may be connected to the second insulation portion (152).

The second pressure surface (182) of the above-mentioned connecting section (1802) can be connected to the third insulation portion (153).

[0243] The above joint support frame (180) may have a joint portion (183) that is joined to the partition wall (105).

[0244] The connecting portion (183) of the above joint support frame (180) may be configured to be placed at some corners on both sides of the first storage room (1101).

[0245] The above-mentioned connecting portion (183) can be implemented in a triangular plate shape, for example.

[0246] One side (one side) of the above-mentioned connecting portion (183) is arranged parallel to the first panel (101), and the other side (the other side) is arranged parallel to the second panel (102).

[0247] One side (one side) of the above-mentioned connecting portion (183) can be connected to a part (e.g., the lower side) of the second pressing surface (182). The other side (the other side) of the above-mentioned connecting portion (183) is connected to a part (e.g., the lower side) of the first pressing surface (181) (the bent end (1811)).

[0248] Here, the above-mentioned connecting portion (183) can be arranged parallel to the above-mentioned partition wall (105).

[0249] The above-mentioned connecting portion (183) can be connected to the partition wall (105).

[0250] The above-mentioned connecting portion (183) can be joined to, for example, the partition wall (105).

[0251] By this, a part of the joint support frame (180) can be integrally joined to the partition wall (105).

[0252] The above joint support frame (180) may be partially supported by a support bracket (210) provided on the third panel (103).

[0253] The above support bracket (210) may be provided in the central area of ​​the third panel (103) along one direction of the first storage room (1101).

[0254] In this embodiment, a part of the joint support frame (180) may be supported by being joined to the partition wall (105). Another part of the joint support frame (180) may be supported by the support bracket (210), thereby significantly reducing the number of separate internal component support members for supporting the joint support frame (180).

[0255] Meanwhile, the shelf support frame (170) is configured to include, for example, an insertion surface (1701) having an insertion hole (1702) into which a coupling protrusion (1423) of the shelf (140) is inserted, a connection surface (1703) provided on the insertion surface (1701) and connected to the joint (150), and / or a connection surface (1705) connecting the insertion surface (1701) and the connection surface (1703).

[0256] The above connecting surface (1705) may be arranged, for example, to face the second pressing surface (182) of the first section (e.g., vertical section) (1801) of the above joint support frame (180).

[0257] The above connecting surface (1705) can be arranged, for example, in the first storage room (1101).

[0258] The above connection surface (1703) may be formed to be bent in a direction away from the first panel (101) from a part (e.g., a rear end) of the connection surface (1705) along one direction of the first storage room (1101), for example.

[0259] That is, the connection surface (1703) extends from the connection surface (1705) along one direction of the first storage room (1101) toward the center (e.g., the center in the left-right direction) of the second panel (102).

[0260] The above connection surface (1703) may be provided with a through hole (1704) formed through the plate surface.

[0261] Although not specifically shown in the drawing, in the through hole (1704), for example, when the second panel (102) is configured to have a high-intensity component support member, a bolt of the high-intensity component support member can be received and connected.

[0262] The above-mentioned through holes (1704) may be implemented as, for example, a plurality of spaced apart holes.

[0263] The above insertion surface (1701) is configured to be bent in a direction approaching the first panel (101) from one end of the connection surface (1705) along one direction of the first storage room (1101).

[0264] Accordingly, the insertion surface (1701) is placed opposite the first pressing surface (181) of the joint support frame (180).

[0265] The above insertion hole (1702) is formed spaced apart from the above insertion surface (1701).

[0266] One side of the above insertion surface (1701) can be coupled to the above joint support frame (180).

[0267] Specifically, the end of the insertion surface (1701) can be joined to the end of the second pressure surface (182) of the joint support frame (180).

[0268] By this, the joint support frame (180) and the shelf support frame (170) form a rectangular cross-section after being combined.

[0269] The load of the shelf (140) coupled to the insertion surface (1701) of the shelf support frame (170) can be distributed and supported by the first pressure surface (181) of the joint support frame (180) and / or the connection surface (1703).

[0270] According to this configuration, the shelf (140) can be prevented from coming off by having the first coupling protrusion (14231) inserted into the insertion hole (1702) of the shelf support frame (170) and then the catch (142312) connected to the back surface of a part (e.g., the lower edge) of the insertion hole (1702).

[0271] The shelf (140) can be prevented from moving by inserting the first coupling protrusion (14231) into the insertion hole (1702) and then inserting the second coupling protrusion (14232) into the insertion hole (1702).

[0272] Meanwhile, a multi-duct cover (190) that covers the surface of the multi-duct (160) is provided in the first area (e.g., rear area) of the first storage room (1101).

[0273] In this embodiment, the multi-duct cover (190) may be configured in a rectangular plate shape, for example, to form the rear wall of the first storage room (1101).

[0276] The two side areas of the multi-duct cover (190) along one direction of the first storage room (1101) may be formed to protrude more than the central area.

[0277] Specifically, the multi-duct cover (190) may be configured, for example, with a multi-duct cover body (1901) disposed on the multi-duct (160) and / or protrusions (1902) formed on both sides of the multi-duct cover body (1901).

[0278] Each of the above protrusions (1902) is arranged on the second insulation part (152) of the joint (150), the joint support frame (180) and / or the shelf support frame (170).

[0279] The above multi-duct cover body (1901) is configured to be placed on one side of the connection surface (1703) of the shelf support frame (170).

[0280] The above multi-duct cover (190) has a connecting portion (1903) that connects the multi-duct cover body (1901) and each of the above protrusions (1902).

[0281] Each of the above connecting parts (1903) is formed at an angle.

[0282] The above connecting portion (1903) is arranged at an angle to the connecting surface (1703) of the shelf support frame (170).

[0283] Each protrusion (1902) of the above multi-duct cover (190) is provided with a penetration portion (1904) formed through which the insertion hole (1702) of the shelf support frame (170) is exposed to the outside.

[0284] The above penetration portion (1904) is formed to have a long length.

[0285] FIG. 15 is a schematic drawing of the interior to explain the joint support frame and support bracket inside the refrigerator body of FIG. 5, FIG. 16 is a front view enlarged of the support bracket area of ​​FIG. 15, FIG. 17 is a perspective view of the joint state of the support bracket and the high internal component support member of FIG. 16, FIG. 18 is an enlarged view of the joint area of ​​the support bracket and the joint support frame of FIG. 16, FIG. 19 is a side view of the support bracket and the joint support frame of FIG. 18, and FIG. 20 is a side view of the separated state of the support bracket and the high internal component support member of FIG. 19.

[0286] Referring to FIG. 6 and FIG. 15 to FIG. 17 together, the refrigerator body (100) may be provided with a support bracket (210) to support the joint support frame (180).

[0288] The above-mentioned connecting portion (2101) can be arranged parallel to the third panel (103).

[0289] The above connecting portion (2102) can be arranged to be connected to the lower surface of the second pressure surface (182) of the above joint support frame (180).

[0290] The above connecting portion (2103) can be placed on the joint support frame (180).

[0292] The surface of the above connecting portion (2103) can be connected to one end of the second pressure surface (182) of the connecting section (1802) of the above joint support frame (180).

[0293] By this, a part (e.g., upper part) (connection section (1802)) of the joint support frame (180) can be prevented from being separated from the second panel (102).

[0294] In this embodiment, the connecting portion (2102) may be configured to have a width corresponding to the width of the second pressing surface (182) of the joint support frame (180), for example, as illustrated in FIG. 18.

[0295] The above connecting portion (2103) may be configured to have a width corresponding to the thickness of the third insulating portion (153) of the above joint (150).

[0296] The above-mentioned connecting portion (2101) may be configured to have an extended width compared to the above-mentioned connecting portion (2102).

[0297] Here, the connecting portion (2102) has the smallest width, and the connecting portion (2103) has a larger width than the connecting portion (2102). The joining portion (2101) may be configured to have a larger width than the connecting portion (2103).

[0300] The above bolts (2202) can be implemented in multiple pieces spaced apart along the length direction of the plate (2201).

[0301] In this embodiment, the bolts (2202) are implemented in three numbers, but this is only an example and is not limited thereto.

[0302] In this embodiment, the case where the high-intensity component support member (220) is coupled to the third panel (103) to couple the support bracket (210) to the third panel (103) is exemplified, but this is merely an example and is not limited thereto. The high-intensity component support member (220) may be coupled to the inner wall of the storage room (110) (the first panel (101), the second panel (102), the third panel (103) and / or the fourth panel (104)) to support other components.

[0303] The plate (2201) of the above-mentioned internal component support member (220) may have a relatively thin thickness.

[0304] The plate (2201) of the above-mentioned internal component support member (220) can be formed to have a thickness thinner than the thickness of the above-mentioned support bracket (210).

[0305] The plate (2201) of the above-mentioned internal component support member (220) can be coupled to the first plate (1301) of the third panel (103).

The partition wall (105) can be coupled to the interior of the first panel (101) and the second panel (102) so that the storage compartment (110) can be partitioned.

[0312] The joint (150) can be joined so as to block the edges of the second panel (102), the first panel (101), and the third panel (103).

[0313] The joint support frame (180) can be coupled to the surface of the above joint (150).

[0314] One end of the above joint support frame (180) can be connected to the partition wall (105). The other end of the above joint support frame (180) can be supported by the above support bracket (210).

[0315] The multi-duct (160) may be coupled between the first insulation portion (151) of the joint (150). The multi-duct cover (190) may be coupled to one side of the joint (150) and / or the multi-duct (160).

[0316] Meanwhile, the shelf (140) can be combined inside the first storage room (1101).

[0317] The above shelf (140) can have a first coupling protrusion (14231) coupled to the insertion hole (1702) of the shelf support frame (170) exposed through the penetration portion (1904) of the multi-duct cover (190).

[0318] Each shelf (140) above can be inserted and connected to the lower insertion hole (1702) by the second coupling protrusion (14232) of each shelf (140) in a state where the catch (142312) of the first coupling protrusion (14231) is connected to a part (e.g., the lower edge) of the corresponding insertion hole (1702).

[0319] Hereinafter, another embodiment of the present invention will be described with reference to FIGS. 21 to 25.

As shown in FIGS. 21 to 23, the refrigerator of the present embodiment includes a refrigerator body (100a), a shelf (140), a joint (150a), and / or a shelf support frame (170a).

[0321] The above refrigerator body (100a) can be implemented in an approximately rectangular parallelepiped shape.

[0322] The refrigerator body (100a) of the present embodiment is configured, as described above, with a partition wall (105) that partitions the storage room (110), a first storage room (1101) provided on one side of the partition wall (105), and / or a second storage room (1102) provided on the other side of the partition wall (105).

[0323] The refrigerator body (100a) may be configured, for example, with a first panel (101) disposed on both sides of the storage compartment (110), a second panel (102a) disposed in the storage compartment (110), and a third panel (103) disposed on one side (e.g., the upper side) of the storage compartment (110).

[0324] The first panel (101), the second panel (102a), and the third panel (103) are assembled to form a perpendicular (right angle) to each other.

[0325] A joint (150a) may be provided at each of the corners forming the boundary between the second panel (102a) and the first panel (101), the corners forming the boundary between the second panel (102a) and the third panel (103), and the corners forming the boundary between the first panel (101) and the third panel (103).

[0326] By this, leakage of cold air through the edges of the second panel (102a), the first panel (101), and the third panel (103) can be suppressed.

[0327] The above joint (150a) may be configured to include, for example, an insulating member.

[0328] By this, cold air leakage through each corner of the storage room (110) can be effectively suppressed.

[0329] In this embodiment, the joint (150a) may be configured to include, for example, a first connecting portion (1501), a second connecting portion (1502), a connecting portion (1503) connecting the first connecting portion (1501) and the second connecting portion (1502), and / or a filling portion (1504) filling the interior (empty space) of at least one of the first connecting portion (1501), the second connecting portion (1502), and the connecting portion (1503).

[0330] Here, the first connecting portion (1501), the second connecting portion (1502) and / or the connecting portion (1503) may be configured to form a right-angled triangle shape, for example, with a synthetic resin member on a plate.

[0331] An empty space having a right-angled triangular cross-section is formed inside the first connecting portion (1501), second connecting portion (1502), and connecting portion (1503), and the foaming liquid of the insulating material can be filled and foamed in the empty space to form the filling portion (1504).

[0332] In this embodiment, among the joints (150a), for example, a joint (150a) positioned at a corner forming a boundary between the second panel (102a) and the first panel (101) may be referred to as an “upper and lower joint.”

[0333] At least one of the first panel (101), the second panel (102a), and the third panel (103) is configured as a vacuum insulator (130) by including a first plate (1301) arranged toward the storage room (110), a second plate (1302) spaced apart from the first plate (1301) and forming a vacuum space (1303) with the first plate (1301), a sealing portion (13012) sealing the first plate (1301) and the second plate (1302), and / or a support (1304) supporting the first plate (1301) and the second plate (1302).

[0334] Although not specifically illustrated in the drawing in this embodiment, a fourth panel (104) may be provided on one side (e.g., the lower side) of the first panel (101) and the second panel (102a), as described above.

[0335] The fourth panel (104) may be composed of, for example, a vacuum insulator (130) having the same structure as the first panel (101), the second panel (102a), and the third panel (103).

[0336] In another embodiment, the fourth panel (104) may be implemented as an insulating material (e.g., polyurethane foam).

[0337] A multi-duct (160) that supplies cold air toward the first storage room (1101) is provided in the first area (e.g., rear area) of the first storage room (1101).

[0338] The above multi-duct (160) can be provided in the rear central area of ​​the first storage room (1101).

[0339] A multi-duct cover (190a) that surrounds the multi-duct (160) may be provided on one side of the multi-duct (160).

[0340] The above multi-duct cover (190a) can be configured to form, for example, the rear wall of the first storage room (1101).

[0341] The above multi-duct cover (190a) can be implemented in a rectangular plate shape.

[0342] The above multi-duct cover (190a) can be placed apart from the second panel (102a) of the first storage room (1101).

[0343] The multi-duct cover (190a) is installed, for example, spaced apart from the second panel (102a), so that a component installation space can be formed between the second panel (102a) and the multi-duct cover (190a). The joint (150a), the multi-duct (160), and / or the shelf support frame (170a) can be provided in the component installation space.

[0344] The ends of both sides of the multi-duct cover (190a) along one direction of the first storage room (1101) may be configured to be connected to the first panel (101).

[0345] According to this configuration, the second panel (102a) can be visually blocked by the multi-duct cover (190a).

[0346] In the above multi-duct cover (190a), for example, a cold air discharge port (191) may be formed through the multi-duct cover (190a) to correspond to the cold air discharge port of the multi-duct (160).

[0347] The first storage room (1101) may be equipped with a shelf (140).

[0348] At least two shelves (140) can be spaced apart from each other, for example, in the storage room (110) (first storage room (1101)).

[0349] The cold air discharge port (191) of the above multi-duct cover (190a) can be formed at a height corresponding to the shelf (140).

[0350] Since the above shelf (140) has the same structure as the shelf (140) described above with reference to FIGS. 9 to 12, a detailed description thereof will be omitted.

[0351] Meanwhile, in this embodiment, the shelf (140) can be supported by a shelf support frame (170a).

[0352] The above shelf support frame (170a) can be formed of a metal member so as to support the load of the shelf (140).

[0353] In this embodiment, the shelf support frame (170a) may be provided on the second panel (102a).

[0354] The above shelf support frame (170a) can be implemented as a pair spaced apart from each other along one direction of the first storage room (1101).

[0355] The shelf support frame (170a), as illustrated in FIG. 23, is configured to include an insertion surface (1701) having an insertion hole (1702) into which a coupling projection (1423) of the shelf (140) is inserted, a side surface (1703a) that is bent at one side (e.g., both sides) of the insertion surface (1701), and / or a connecting surface (1704a) that is bent at the side surface (1703a) and connected to the second panel (102a).

[0356] Each of the above shelf support frames (170a) can be placed on the multi-duct cover (190a).

[0357] The above multi-duct cover (190a) may each have a penetration portion (192) formed therethrough so that the insertion hole (1702) of the shelf support frame (170a) can be exposed to the outside.

[0358] Each of the above penetration portions (192) can be implemented as a rectangular shape having a long length in one direction (e.g., up and down).

[0359] In this embodiment, the connection surface (1704a) may be configured to have different widths.

[0360] The above connection surface (1704a) may have a second connection surface (17041a) extending in a first direction (right side in the drawing) based on the side surface (1703a) and / or a first connection surface (17042a) extending in a second direction of the storage room (110).

[0361] In this embodiment, the second connection surface (17041a) may be configured such that, for example, the width along one direction (e.g., left-right direction) of the storage room (110) (first storage room (1101)) is larger than the width of the first connection surface (17042a).

[0362] In this embodiment, one area of ​​the joint (150a) can be inserted between the first connection surface (17042a) of the shelf support frame (170a) and the second panel (102a).

[0363] By this, direct connection between the first connection surface (17042a) of the shelf support frame (170a) and the second panel (102a) (first plate (1301)) can be suppressed.

[0364] According to this configuration, heat transfer between the first connection surface (17042a) of the shelf support frame (170a) and the second panel (102a) can be suppressed.

[0365] The first connecting portion (1501) of the above joint (150a) is provided with an extension portion (15011) extending away from the first panel (101).

[0366] The above extension (15011) can be inserted between the second panel (102a) and the shelf support frame (170a) (first connection surface (17042a)).

[0367] A high internal component support member (220a) that supports the shelf support frame (170a) is provided in the interconnection area between the shelf support frame (170a) and the second panel (102a).

[0368] Specifically, the high internal component support member (220a) may be provided between the second connection surface (17041a) of the shelf support frame (170a) and the second panel (102a).

[0369] As described above, the above-mentioned internal component support member (220a) may be configured with a plate (2201) coupled to the second panel (102a) and / or a bolt (2202) protruding from the plate (2201).

[0370] The above plate (2201) can be formed of, for example, a metal member.

[0371] The above plate (2201) can be implemented in a rectangular plate shape, for example.

[0372] The above bolt (2202) has, for example, a rod shape and a male screw portion (22021) can be formed.

[0373] One end of the above bolt (2202) can be bonded to the surface of the above plate (2201).

[0374] A bolt hole (170411a) is formed through the second connection surface (17041a) of the shelf support frame (170a) so that the bolt (2202) can pass through.

[0375] The above bolt hole (170411a) is formed in multiple pieces spaced apart from each other on the second connection surface (17041a).

[0376] Although not specifically shown in the drawing, a nut may be coupled to the bolt (2202) of the high-intensity component support member (220a). As a result, the shelf support frame (170a) may be integrally coupled to the second panel (102a).

[0377] Meanwhile, in the present embodiment, the support (1304) of the second panel (102a) is configured to include at least two bars (13041) spaced apart from each other between the first plate (1301) and the second plate (1302).

[0378] One end of each of the at least two bars (13041) may be connected to the first plate (1301). The other end is connected to the second plate (1302).

[0379] By this, the first plate (1301) and the second plate (1302) can be supported by the at least two bars (13041) and prevented from approaching each other.

[0380] In this embodiment, one or more bars may be arranged in the first region (e.g., rear region) of the shelf support frame (170a) and / or the first region (e.g., rear region) (1021a) of the high-intensity component support member (220a) (hereinafter referred to as “the first region (e.g., rear region) (1021a) of the shelf support frame (170a)”).

[0381] Here, the first region (e.g., rear region) (1021a) of the shelf support frame (170a) may mean the area between the ends of the connecting surfaces (1704a) where the shelf support frame (170a) and the second panel (102a) are connected and the load of the shelf (140) is directly applied.

[0382] By this, deformation and / or damage to the second panel (102a) caused by the load of the shelf (140) can be suppressed.

[0383] In this embodiment, as illustrated in FIG. 23, two bars are arranged in the first region (e.g., rear region) (1021a) of the shelf support frame (170a), but this is merely an example and is not limited thereto.

[0384] Meanwhile, as illustrated in FIGS. 24 and 25, the second panel (102b) is configured with a strength reinforcement section (1305) in which the density of the bars (13041) in the first region (e.g., rear region) of the shelf support frame (170a) is higher than the density of the bars (13041) in the surrounding region.

[0385] By this, deformation of the second panel (102b) caused by the load of the shelf (140) can be suppressed.

[0386] The second panel (102b) of the present embodiment can be applied when the capacity of the shelf (140) is configured to be relatively large.

[0387] By this, deformation of the second panel (102b) caused by the increased load of the shelf (140) can be effectively suppressed.

[0388] In this embodiment, the bar (13041) arranged in the first region (e.g., rear region) (the strength reinforcement section (1305)) of the shelf support frame (170a) may be formed to have the same shape and size as the bar (13041) arranged in the peripheral region, and the spacing between the bars (13041) may be configured to be small.

[0389] Meanwhile, as illustrated in FIGS. 26 and 27, the second panel (102c) may be configured with a heat transfer suppression section (1306) in which the density of the bars (13041) in the first region (e.g., rear region) of the shelf support frame (170a) is configured to be smaller than the density of the bars (13041) in the peripheral region.

[0390] According to this configuration, the formation of a heat transfer path between the shelf support frame (170a) and the second plate (1302) of the second panel (102c) can be suppressed.

[0391] By this, the leakage of cold air due to the installation of the shelf support frame (170a) can be suppressed. Conversely, the inflow of heat from the outside of the refrigerator body (100a) to the inside of the first storage chamber (1101) due to the connection between the second plate (1302) of the second panel (102c) and the shelf support frame (170a) can be suppressed.

[0392] In this embodiment, the bar (13041) is not installed in the heat transfer suppression section (1306).

[0393] In this embodiment, a case in which the bar (13041) is not installed in the heat transfer suppression section (1306) is exemplified, but this is only an example and is not limited thereto.

[0394] In another embodiment, the heat transfer suppression section (1306) may be configured so that the bars (13041) are installed with a larger spacing than the spacing of the bars (13041) in the peripheral area.

[0395] In this embodiment, the length (e.g., width in the left-right direction) of the heat transfer suppression section (1306) along one direction (e.g., left-right direction) of the refrigerator body (100a) is exemplified as being formed to be larger than the width (e.g., left-right direction) of the shelf support frame (170a) along one direction (e.g., left-right direction), but this is merely an example and is not limited thereto.

[0396] Meanwhile, as shown in FIGS. 28 and 29, the second panel (102d) is configured with a first bar (130411) and a second bar (130412) having different thicknesses.

[0397] In this embodiment, the first bar (130411) has a first thickness (D1), and the second bar (130412) is configured to have a second thickness (D2) that is thicker than the first thickness (D1).

[0398] The above second bar (130412) is provided in the first region (e.g., rear region) of the shelf support frame (170a).

[0399] Here, the first region (e.g., rear region) of the shelf support frame (170a) in which the second bar (130412) is provided may be referred to as a “strength reinforcement section (1307)” in that the support strength is reinforced by the second bar (130412).

[0400] The above first bar (130411) is placed in the remaining area of ​​the second panel (102d) excluding the first area (e.g., rear area) (strength reinforcement section (1307)) of the shelf support frame (170a).

[0401] By this, deformation and / or damage to the first region (e.g., rear region) of the shelf support frame (170a) caused by the load of the shelf (140) can be suppressed.

[0402] Specific embodiments of the present invention have been illustrated and described above. However, the present invention may be implemented in various forms without departing from its spirit or essential characteristics. Therefore, the embodiments described above should not be limited to the specific details for implementing the invention.

[0403] Even if embodiments are not specifically listed in the detailed description above, they should be broadly interpreted within the scope of the technical concept defined in the appended claims. Furthermore, all changes and modifications that fall within the technical scope of the claims and their equivalents should be encompassed by the appended claims.
