[0019] According to embodiments of the present invention, the following effects can be achieved.

[0020] First, a reinforcing plate may be applied as a strength reinforcement structure made of a metal material. A portion (e.g., left side and / or right side) of the reinforcing plate is connected to a second plate (also referred to as an 'outer case') of one of first panels forming a side surface (e.g., left and right side surfaces) of a main body and to a second plate of the other of the first panels, respectively, so as to maintain height-direction flatness and structural shape of a side surface of the main body during a vacuum exhaust process.

[0021] Second, the first panel may be configured as a vacuum adiabatic body, and the vacuum adiabatic body may be configured to include a first plate (also referred to as an 'inner case'), a second plate, and a support. A third plate may be provided to overlap with the second plate. A side plate extending from a portion (e.g., a front end portion) of the first plate may be sealed in connection with the second plate.

[0022] The reinforcing plate and the second plate may be disposed on the same plane and connected to each other by welding, etc. A plate coupling portion may extend from the reinforcing plate toward the second plate in order to connect a hot line plate and the second plate. A second plate extension extends from the second plate toward the hot line plate, so that the plate coupling portion and a portion (e.g., a front end portion) of the second plate are interconnected.

[0023] Accordingly, the plate coupling portion of the reinforcing plate and the second plate are connected to each other in the same plane, thereby minimizing heat loss by reducing a thickness and an area of a thermal insulator transferred from the reinforcing plate to the second plate.

[0024] The plate coupling portion, a third plate extension extending from the third plate, and a side plate extension portion extending from a side plate are disposed to overlap at a portion (e.g., a front end portion) of the first panel.

[0025] In order to couple at least two of the plate coupling portion, the third plate, and the side plate, a first coupling hole may be formed in the plate coupling portion. A second coupling hole may be formed in the third plate extension portion. A third coupling hole may be formed in a side plate extension portion. A first coupler such as a screw, etc., may be coupled to at least one of the plate coupling portion, the third plate extension portion, and the side plate extension portion by penetrating at least one of the first to third coupling holes.

[0026] Accordingly, the reinforcing plate is coupled to the plate coupling portion, the third plate extension portion, and the side plate extension portion which overlap with each other, thereby reinforcing a mutual support strength of the reinforcing plate and the second plate.

[0027] Third, a hinge is coupled to one surface of the partition wall via a hinge supporter. The hinge includes a hinge support portion on which a hinge coupling portion coupled to the hinge supporter, and a hinge shaft protrude upward. The reinforcing plate is coupled between the hinge coupling portion and the hinge supporter.

[0028] When the first to third coupling holes are projected in one direction onto the same virtual plane as the hot line plate, a coupling hole located on one side (e.g., lower side) of the first to third coupling holes may be disposed to overlap in one direction with the third hinge coupling hole of the reinforcing plate.

[0029] Accordingly, when a first coupler coupling the reinforcing plate, the third plate extension portion, and the side plate extension portion to which the second plate extension portion is connected is projected in one direction onto the same virtual plane as the reinforcing plate, a first coupler is disposed to overlap in one direction with a second coupler coupling the hinge coupling portion, the reinforcing plate, and the hinge supporter, and as a result, a combination value of a coupling force of the first coupler and a coupling force of the second coupler is greater than a unidirectional (e.g., left-right direction) force generated between one of the first panels and the other of the first panels during a vacuum exhaust process, thereby being more effective in maintaining the flatness and structural shape of the first panel of the main body (also referred to as 'cabinet').

[0030] Fourth, the plate coupling portion extends from the reinforcing plate and is connected to the second plate, and as a result, y the reinforcing plate can be utilized without additional heat insulation loss.

[0031] Fifth, the reinforcing plate coupled to the partition wall is coupled between the hinge and the hinge supporter to support the hinge together with the hinge supporter, thereby further improving the structural strength of the hinge and the hinge supporter.Description of Drawings

[0109] The hook protrusion 120 is disposed spaced apart from the deco 119. Hook coupling portions 121 may be formed on portions (e.g., both sides) of the panel and portions (e.g., both sides) of the partition wall 107 so that the hook protrusion 120 is locked thereon.

[0110] At least two hook protrusions 120 may be disposed spaced apart in a lengthwise direction of each panel or the partition wall 107.

[0111] Referring to FIG. 9, the hook protrusions 120 of the deco 119 are shown which are coupled to the hook coupling portions 121 (see FIG. 11) formed on one surface and the other surface of the injection molding 1073 of the partition wall 107, respectively.

[0112] Accordingly, the deco 119 may be firmly coupled to the panel or partition wall 107)by the hook protrusions 120.

[0113] An opening portion 122 is formed to penetrate in one direction in the deco 119 coupled to one surface of the partition wall 107 so that the reinforcing plate 123 to be described later is exposed toward the outside of the main body 100. The opening portion 122 may be formed in a rectangular shape. A size of the opening portion 122 is formed to correspond to a size of the reinforcing plate 123.

[0114] The reinforcing plate 123 is configured to transfer heat dissipated from the hot line 118 to the door. Accordingly, the reinforcing plate 123 may be named a hot line (118) plate.

[0115] The reinforcing plate 123 may be formed in the rectangular shape. The reinforcing plate 123 may be made of a metal material. The reinforcing plate 123 may be disposed between the hinge 113 and the hinge supporter 110.

The reinforcing plate 123 is received in the opening portion 122 of the deco 119. One surface of the reinforcing plate 123 and one surface of the deco 119 may be disposed to form the same surface (e.g., vertical plane). An corner of the reinforcing plate 123 and an corner of the deco 119 may be connected on the same straight line.

[0117] Curling portions 1231 and 1232 may be formed on a portion (e.g., top and / or bottom) of the reinforcing plate 123.

The curling portions 1231 and 1232 may include a first curling portion 1231 formed on a portion (e.g., top) of the reinforcing plate 123 and / or a second curling portion 1232 formed on the other portion (e.g., bottom) of the reinforcing plate 123. A surface of each of the first curling portion 1231 and the second curling portion 1232 may be coupled to be connected to the partition wall injection molding 1073.

[0118] When the first storage chamber door 108 and the second storage chamber door 109 are closed, an one-end (e.g., top) corner of the reinforcing plate 123 is positioned higher than one end (e.g., bottom) of the first storage chamber door 108. The other-end (e.g., bottom) corner of the reinforcing plate 123 is positioned lower than one end (e.g., top) of the second storage chamber door 109.

[0119] Accordingly, as a boundary line between the reinforcing plate 123 and the deco 119 is covered by the first storage chamber door 108 and the second storage chamber door 109, there is an advantage of an aesthetically pleasing appearance. Even when the first storage chamber door 108 and the second storage chamber door 109 are opened, the reinforcing plate 123 and the deco 119 are positioned on the same plane, so that it is possible to achieve a neat appearance.

[0120] A coupling hook 124 may be provided on a surface of the reinforcing plate 123. The coupling hook 124 is configured to couple the reinforcing plate 123 to one surface of the partition wall 107. The coupling hook 124 may be formed in a flat plate shape.

[0124] The coupling hook 124 is inserted through the hook locking portion 125 and then slides in one direction, so that the reinforcing plate 123 may be coupled to the partition wall 107.

[0125] A third hinge coupling hole 126 is provided in the reinforcing plate 123. The third hinge coupling hole 126 is formed to penetrate in one direction. The third hinge coupling hole 126 may be disposed to overlap with the above-described first hinge coupling hole 1121 and second hinge coupling hole 1141.

[0126] A second coupler (144) such as a screw, etc., may sequentially penetrate the second hinge coupling hole 1141, the third hinge coupling hole 126, and the first hinge coupling hole 1121 to be coupled to the hinge coupling portion 114, the reinforcing plate 123, and the hinge supporter 110.

[0127] The third hinge coupling hole 126 may be formed on one side (e.g., right side) of a peripheral portion of the reinforcing plate 123 and / or on one side (e.g., left side) of the peripheral portion of the reinforcing plate 123. In the embodiment, at least two third hinge coupling holes 126 are shown which are formed on the peripheral portion (e.g., right side and / or left side) of the reinforcing plate 123.

[0128] A portion of the hot line 118 may be received in the recess 1071 of the partition wall 107. The protrusion portion 112 of the hinge supporter 110 may be received in the recess 1071 of the partition wall 107.

[0129] A receiving space formed in the recess 1071 of the partition wall 107 may be partitioned into three spaces. For example, a first space among the three spaces is a space formed between the reinforcing plate 123, the recess 1071 of the partition wall 107, and a side surface portion of one side (e.g., upper side) of the protrusion portion 112 of the hinge supporter 110. A second space among the three spaces is a space formed between the reinforcing plate 123, the recess 1071 of the partition wall 107, and a side surface portion of one side (e.g., lower side) of the protrusion portion 112 of the hinge supporter 110. A third space among the three spaces is a space formed between the protrusion portion 112 of the hinge supporter 110, a surface of the insertion portion 111, and the recess 1071 of the partition wall 107.

[0130] The hot line 118 may be disposed in a second space The hot line 118 may be positioned to be connected to a surface of the reinforcing plate 123 which is connected to a connection surface of the second storage chamber door 109.

[0131] The hot line 118 is disposed to be connected to at least one surface of the reinforcing plate 123, for example, the surface of the reinforcing plate 123. One surface of the reinforcing plate 123 may be connected to a gasket of the first storage chamber door 108 and / or a gasket of the second storage chamber door 109.

[0132] Accordingly, the reinforcing plate 123 may transfer the heat generated by the hot line 118 to the connection surface of the first storage door chamber 108 and / or the second storage chamber door 109.

[0133] A temperature of the second storage chamber 106 is lower than a temperature of the first storage chamber 105. A difference between an external temperature of the refrigerator and an internal temperature of the second storage chamber 106 is greater than a difference between the external temperature of the refrigerator and an internal temperature of the first storage chamber 105.

[0134] A reason for installing the hot line 118 in the second space is to prevent occurrence of more dew formation around the second storage chamber 106 than around the first storage chamber 105 due to a temperature difference between the second storage chamber 106 and the first storage chamber 105.

[0135] The reinforcing plate 123 is provided with a stepped portion 127, an extension portion 128, a step portion 129, and / or a plate coupling portion 130.

[0136] A first stepped portion 1271, a first extension portion 1281, a first step portion 1291, and a first plate coupling portion 1301 formed on one side (e.g., right side) of the reinforcing plate 123 are different from a second stepped portion 1272, a second extension portion 1282, a second step portion 1292, and a second plate coupling portion 1302 formed on the other side (e.g., left side) of the reinforcing plate 123 only in formation position, but have the same configuration and effect, so duplicate description will be omitted. Unless otherwise specified in the following description, the description of the stepped portion 127, the extension portion 128, the step portion 129, and the plate coupling portion 130 may be applied to both the first and second stepped portions 1271 and 1272, first and second extension portions 1281 and 1282, first and second step portions 1291 and 1292, and first and second plate coupling portions 1301 and 1302.

[0137] The stepped portion 127 may be formed to be stepped from one end of the reinforcing plate 123 toward the hinge supporter 110. An end portion of the deco 119 may be disposed to be connectable to the stepped portion 127.

[0138] The surface of the reinforcing plate 123 and the surface of the deco 119 may be disposed on the same plane.

[0139] The extension portion 128 is formed to extend obliquely from one end of the stepped portion 127 toward an inner side of the deco 119.

[0140] The step portion 129 may be formed to extend from one end of the extension portion 128 toward the second plate 133 of the first panel 103.

[0141] The plate coupling portion 130 is formed to extend from a portion (e.g., a rear end) of the step portion 129. The plate coupling portion 130 may be disposed to overlap with the second plate 133 of the first panel 103. A first coupling hole may be formed to penetrate the plate coupling portion 130 in one direction.

[0142] First coupling holes 1303a and 1303b may be disposed spaced apart from the plate coupling portion 130.

[0143] The plate coupling portion 130 may be coupled to the second plate 133 of the first panel 103 to be described later by the first coupler 143 such as the screw, etc.

[0144] The stepped portion 127, the extension portion 128, and the step portion 129 are separately designated only for convenience of description, and at least one of the stepped portion 127, the extension portion 128, and the step portion 129 may be omitted. For example, only the plate coupling portion 130 may be provided on one side (e.g., left side and / or right side) of the reinforcing plate 123, or one or more of the stepped portion 127, the extension portion 128, and the step portion 129 and the plate coupling portion 130 may be provided on one side (e.g., left side and / or right side) of the reinforcing plate 123.

[0145] The stepped portion 127, the extension portion 128, the step portion 129, and the plate coupling portion 130 may be formed with the same length in one direction (e.g., vertically).

[0146] The first hot line 118a may be disposed between an outer side of the reinforcing plate 123 and an inner side of the deco 119. At least a portion of the second hot line 118b connected to the first hot line 118a is disposed on the reinforcing plate 123.

[0147] Therefore, in order to connect the first hot line 118a and the second hot line 118b, a space is required to insert the second hot line 118b from the reinforcing plate 123 to an inner side of the reinforcing plate 123.

[0148] In order to form a hot line insertion cavity, a unidirectional (e.g., vertical) length of the stepped portion 127, the extension portion 128, the step portion 129, and the plate coupling portion 130 is formed shorter than a unidirectional (e.g., vertical) length of the reinforcing plate 123.

[0149] The stepped portion 127, the extension portion 128, the step portion 129, and the plate coupling portion 130 may be disposed eccentrically from a unidirectional (e.g., vertical) center of the reinforcing plate 123.

[0150] Accordingly, a hot line (118) insertion space may be formed between a portion (e.g., bottom) of the eccentrically displaced moved stepped portion 127, extension portion 128, step portion 129, and plate coupling portion 130 and a portion (e.g., bottom) of the reinforcing plate 123. The second hot line 118b may be inserted from one side of the reinforcing plate 123 into the other side of the reinforcing plate 123.

[0151] The second hot line 118b may be formed to extend from the reinforcing plate 123 to the inner side of the reinforcing plate 123 without forming a hot line (118} through-hole in at least one of the stepped portion 127, the extension portion 128, and the step portion.

[0152] The vacuum adiabatic body 131 shown in FIG. 7 forms the first panel 103. The vacuum adiabatic body 131 includes a first plate 132, a second plate 133, a side plate 134, and a panel supporter 137.

[0153] The first plate 132 is disposed to face an external space of the refrigerator. The second plate 133 is disposed to face a storage chamber which is an internal space of the refrigerator. The first plate 132 and the second plate 133 may be disposed spaced part in one direction.

[0154] A second plate extension portion 1331 may be formed to extend further from the second plate 133. The second plate extension portion 1331 may be formed to be bent in a thickness direction of a vacuum space portion 136.

[0155] The second plate extension portion 1331 may include a first straight portion 1332 extending in one direction of the first panel 103 and / or a second straight portion 1333 extending at a predetermined angle from the first straight portion 1332 to the first panel 103.

[0156] The side plate 134 is formed to extend from the first plate 132 toward the second plate 133. The side plate 134 may be formed as one body with the first plate 132.

[0157] The side plate 134 may include a first curved portion 1341 connecting the first plate 132 and the side plate 134, a second curved portion 1342 connecting the side plate 134 and the second plate 133, and / or a side plate extension portion 1343 extending from the second curved portion 1342.

[0158] The side plate extension portion 1343 may be connected to the second plate extension portion 1331 or a third plate extension portion 128 to be described later.

[0159] The side plate extension portion 1343 may be formed to be bent in the thickness direction of the vacuum space portion 136. The side plate extension portion 1343 includes a first straight portion 1344 extending in one direction of the first panel 103 and / or a second straight portion 1345 extending from the first straight portion 1344 to the first panel 103 at a predetermined angle.

[0160] The second plate extension portion 1331 and the side plate extension portion 1343 are disposed to overlap in one direction.

[0161] The first straight portion 1332 of the second plate extension portion 1331 and the first straight portion 1344 of the side plate extension portion 1343 are disposed to overlap in one direction. The second straight portion 1333 of the second plate extension portion 1331 and the second straight portion 1345 of the side plate extension portion 1343 are disposed to overlap in one direction.

[0162] A third plate 135a may be further provided on the second plate 133. The third plate 135a may be disposed in close contact between a support plate 139 of the panel supporter 137 and the second plate 133 without a gap. The third plate 135a may reinforce a strength by increasing the thickness of the second plate 133.

[0163] A third plate extension portion 1351 may be formed to extend further from the third plate 135a.

[0164] The third plate extension portion 1351 may be formed to be bent in the thickness direction of the vacuum space portion 136. The third plate extension portion 1351 includes a first straight portion 1352 extending in one direction of the first panel 103 and / or a second straight portion 1352 extending from the first straight portion 1353 at a predetermined angle to the first panel 103.

[0165] The third plate extension portion 1351 may be disposed between the second plate extension portion 1331 and the side plate extension portion 1343. The second plate extension portion 1331, the third plate extension portion 1351, and the side plate extension portion 1343 may be disposed to overlap in one direction.

[0166] A sealing portion may be formed between the second plate extension portion 1331, the third plate extension portion 1351, and the side plate extension portion 1343. Accordingly, the vacuum space portion 136 is formed between the first plate 132 and the second plate 133, or between the first plate 132 and the third plates 135a and 135b, or between the first plate 132, the side plate 134, and the third plates 135a and 135b.

[0167] The first straight portion 1332 of the second plate extension portion 1331 and the first straight portion 1332 of the third plate extension portion 1351, and the first straight portion 1344 of the side plate extension portion 1343 may be disposed to overlap in one direction. The second straight portion 1333 of the second plate extension portion 1331, the second straight portion 1353 of the third plate extension 1351, and the second straight portion 1345 of the side plate extension portion 1343 may be arranged to overlap.

[0168] The third plate extension 1351 may reinforce the strength by increasing the thicknesses of the side plate extension portion 1343 and the second plate extension portion 1331.

[0169] The second straight portion 1345 of the side plate extension portion 1343 and the second straight portion 1353 of the third plate extension portion 1351 are disposed to overlap with the plate coupling portion 130.

[0170] The second straight portion 1333 of the second plate extension portion 1331 of the side plate extension portion 1343, and the plate coupling portion 130 may be disposed on the same plane or may be disposed not to overlap with each other.

[0171] One end of the second straight portion 1333 of the second plate extension portion 1331 and one end of the plate coupling portion 130 may be connected to each other. The second straight portion 1333 of the second plate extension portion 1331 and the plate coupling portion 130 may be connected by welding, etc.

[0172] The second straight portion 1333 of the second plate extension portion 1331 may extend to overlap with the plate coupling portion 130.

[0173] However, when the plate coupling portion 130, the second plate extension portion 1331, the third plate extension portion 1351, and the side plate extension portion 1343 are disposed to overlap with each other, the increase in thickness may increase rigidity, but a heat transfer area increases, so there is a problem that heat loss may increase through a path of heat transfer of cold air in the storage chamber from the first plate 132 to the second plate 133.

[0174] Therefore, in the embodiment, the second plate extension portion 1331 does not overlap with the plate coupling portion 130 and is disposed on the same plane and connected to the plate coupling portion 130, thereby minimizing heat loss while securing a required strength of the plate.

[0175] A first coupling hole 1303a is formed in the plate coupling portion 130. There may be provided a plurality of first coupling holes 1303a. The first coupling holes 1303a may be disposed spaced apart from each other.

[0176] A second coupling hole 1354 is formed in the second straight portion 1353 of the third plate extension portion 1351. There may be provided a plurality of second coupling holes 1354. At least two second coupling holes 1354 may be disposed spaced apart from each other.

[0177] A third coupling hole is formed in the second straight portion 1345 of the side plate extension portion 1343. There may be a plurality of third coupling holes. At least two third coupling holes 1346 may be disposed spaced apart from each other.

[0178] At least two or more of the first coupling hole 1303a, the second coupling hole 1354, and the third coupling hole 1346 are disposed to overlap with each other. The first coupler 143 such as the screw, etc., may be coupled to the plate coupling portion 130, the third plate extension portion 1351, and the side plate extension portion 1343 through the first to third coupling holes 1346, so that the plate coupling portion 130, the third plate extension portion 1351, and the side plate extension portion 1343 may be coupled to each other.

[0179] Accordingly, the reinforcing plate 123 may be connected to the second plate 133 of the first panel 103 through the plate coupling portion 130. The reinforcing plate 123 connects the second plate 133 of one 1031 of the first panels and the second plate 133 of the other 1032 of the first panels to maintain the flatness and a structural shape of the first panel 103 of the main body 100 during a vacuum exhaust process.

[0180] Moreover, the reinforcing plate 123 connects the second plates 133 of the first panels 1031 and 1032 to minimize a central portion of the first panel 103 from being formed convex or concave during the vacuum exhaust process.

[0181] Referring to FIG. 8, when the first to third coupling holes 1303, 1354, and 1346 are projected in one direction onto the same virtual plane as the reinforcing plate 123, a coupling hole located on one side (e.g., upper side) of the first to third coupling holes 1303, 1354, and 1346 is positioned higher than the third hinge coupling hole 126 of the reinforcing plate 123.

[0182] Referring to FIG. 9, when the first to third coupling holes 1303, 1354, and 1346 are projected in one direction onto the same virtual plane as the reinforcing plate 123, a coupling hole located on one side (e.g., lower side) of the first to third coupling holes 1303, 1354, and 1346 may be disposed to overlap with the third hinge coupling hole 126 of the reinforcing plate 123 in one direction.

[0183] Accordingly, when the first coupler 143 coupling the reinforcing plate 123, the third plate extension portion 1351, and the side plate extension portion 1343 to which the second plate extension portion 1331 is connected is projected in one direction onto the same virtual plane as the reinforcing plate 123, the first coupler 143 is disposed to overlap in one direction with the second coupler 144 coupling the hinge coupling portion 114, the reinforcing plate 123, and the hinge supporter 110, and as a result, a combination value of a coupling force of the first coupler 143 and a coupling force of the second coupler 144 is greater than a unidirectional (e.g., left-right direction) force generated between one 1031 of the first panels 1031 and the other 1032 of the first panels during the vacuum exhaust process, thereby being more effective in maintaining the flatness and structural shape of the first panel 103 of the main body 100 (also referred to as 'cabinet').

[0184] In the reinforcing plate 123, the plate coupling portion 130 extends and is connected to the second plate 133, and as a result, utilization is possible without additional heat-insulation loss.

[0185] Moreover, the reinforcing plate 123 coupled to the partition wall 107 may be made of the metal material. The reinforcing plate 123 is coupled between the hinge 113 and the hinge supporter 110 to support the hinge 113 together with the hinge supporter 110, thereby further improving the structural strength of the hinge 113.

[0186] The first hinge shaft 116a and the second hinge shaft 116b are formed to protrude to overlap with one surface and the other surface of the hinge support portion 115.

[0187] A load of the door is applied to the hinge shaft 116 and stress concentration occurs. In order to well withstand the stress concentration acting on the hinge shaft 116, the hinge shaft 116 may be disposed between a virtual first extension line 141 extending in one direction from the first plate 132 and a virtual second extension line 142 extending in one direction from the second plate 133.

[0188] The hinge shaft 116 may be disposed to overlap with the vacuum adiabatic body 131 of the first panel 103.

[0189] More specifically, the hinge shaft 116 may be disposed adjacent to the first extension line 141.

[0190] The panel supporter 137 includes at least two bars 138, a support plate 139, and a connection plate 140. The at least two bars 138 including the vacuum adiabatic body 131 of the first panel 103 extend between the first plate 132 and the second plate 133. The at least two bars 138 are disposed spaced apart in one direction.

[0191] The support plate 139 may be disposed to overlap with the first plate 132. The support plate 139 extends in one direction of the first panel 103. One end of each of the at least two bars 138 facing the first plate 132 may be connected.

[0192] The connection plate 140 may be disposed to overlap with the second plate 133. The connection plate 140 extends in one direction of the first panel 103. The other end of each of the at least two bars 138 facing the second plate 133 may be connected.

[0193] A thickness of the support plate 139 may be formed to be equal to or thicker than a thickness of the connection plate 140.

[0194] A third plate 135b may be additionally provided between the first plate 132 and the support plate 139. Accordingly, the third plate 135b may reinforce a strength of the first plate 132 by increasing the thickness of the first plate 132.

[0195] The hinge shaft 116 may be disposed adjacent to a virtual extension line extending in one direction from any one of the first plate 132, the support plate 139, and / or the third plate 135b adjacent to the first plate 132.

[0196] The bar 138 may be formed with a different thickness or diameter in a lengthwise direction. The bar 138 may be formed such that a diameter gradually increases from one end portion of the bar 138 close to the second plate 133 toward the other end portion of the bar 138 close to the first plate 132.

[0197] Accordingly, a reinforcing structure of the third plate 135b, which reinforces the strength of the first plate 132, the support plate 139 with an increased thickness, and the bar 138 with an increased diameter at one end, may further increase a support strength of the hinge 113 for rotation of the door by offsetting an increase in stress concentration on the hinge shaft 116.

[0198] An end portion of the second coupler 144 that couples the hinge 113, the reinforcing plate 123, and / or the hinge supporter 110 may be inserted and coupled to an inner side of the partition wall 107 by penetrating the protrusion portion 112 of the hinge supporter 110.

[0199] In this case, one of the at least two second couplers 144 may be disposed close to the first plate 132. The other one of the at least two second couplers 144 may be disposed relatively far from the first plate 132.

[0200] Heat transfer may occur between the second coupler 144 close to the first plate 132, and the first plate 132. An arrow dotted line indicates a heat transfer path. In this case, a heat insulator 1074, for example, a PU foam, is embedded between the second coupler 144 and the first plate 132.

[0201] Accordingly, the heat transfer between the second coupler 144 and the first plate 132 may be minimized.

[0202] FIG. 11 is an exploded conceptual view showing the hinge 113, a deco 219, the reinforcing plate 123, and the partition wall 107 according to another embodiment of the present invention.

[0203] The embodiment is different from the embodiments of FIGS. 1 to 10 described above in that the deco 219 covers the reinforcing plate 123 so that the reinforcing plate 123 is not exposed to the outside.

[0204] Since other components are the same as or similar to the embodiments of FIGS. 1 to 10 described above, redundant description will be omitted.

[0205] The partition wall injection molding 1073 includes a front cover 1073a, a back cover, a side cover 1073b, an upper cover 1073c, and / or a bottom cover. The front cover 1073a forms a surface of the partition wall 107. The back cover forms a surface of the partition wall 107. The side cover 1073b forms a portion (e.g., left and right side surface) of the partition wall 107. The upper cover 1073c forms a surface of the partition wall 107. The upper cover 1073c may be disposed to face the first storage chamber 105. The bottom cover forms a surface of the partition wall 107. The bottom cover may be disposed to face the second storage chamber 106.

[0206] An insulator 1074, for example, a PU foam, may be embedded in the front cover 1073a, the back cover, the side cover 1073b, the upper cover 1073c, and / or the bottom cover. The heat insulator 1074 is not limited thereto and may be implemented as a vacuum adiabatic body 131 having the vacuum space portion (136) formed therein.

[0207] The hinge supporter 110 may be installed on a peripheral portion of the front cover 1073a. The protrusion portion 112 of the hinge supporter 110 may be inserted and protrude through the receiving portion 1072 of the recess 1071 formed on the peripheral portion of the front cover 1073a. The insertion portion 111 of the hinge supporter 110 may be inserted and coupled into the front cover 1073a.

[0208] A hook locking portion 125 is formed on the front cover 1073a. A coupling hook 124 protruding on the surface of the reinforcing plate 123 is locked and coupled to the hook locking portion 125, so the reinforcing plate 123 may be coupled to the front cover 1073a.

[0209] The deco 219 may be formed in a rectangular plate shape. The deco 219 may be formed to have a larger size than the reinforcing plate 123. The deco 219 is installed on the surface of the reinforcing plate 123 so as to cover the surface of the reinforcing plate 123.

[0210] The hinge 113 is installed on a surface of the deco 219. The deco 219 and the reinforcing plate 123 are disposed between the hinge 113 and the hinge supporter 110.

[0211] A fourth hinge coupling hole 219a is formed to penetrate an end portion of the deco 219 in one direction. At least two fourth hinge coupling holes 219a are disposed spaced apart in one direction.

[0212] The second coupler 144 coupling the hinge 113 and the hinge supporter 110 may couple the deco 219, the reinforcing plate 123, and the hinge supporter 110 through the second hinge coupling hole 1141 of the hinge coupling portion 114, the fourth hinge coupling hole 219a of the deco 219, the third hinge coupling hole 126 of the reinforcing plate 123, and the first hinge coupling hole 1121 of the hinge supporter 110.

[0213] The description of the partition wall 107 in the embodiment may be applied to the embodiments of FIGS. 1 to 10 described above.

[0214] Since other components are the same as or similar to the embodiments of FIGS. 1 to 10, redundant description will be omitted.

[0215] FIG. 12 is a conceptual view showing a coupling structure of the hinge 113, the reinforcing plate 123, and the hinge supporter 310 according to another embodiment of the present invention.

[0216] The embodiment is different from the embodiment of FIGS. 1 to 11 in that a supporter extension portion 321 is additionally provided in the hinge supporter 310.

[0217] The supporter extension portion 321 may include a first extension portion 322 and a second extension portion 323.

[0218] The first extension portion 322 extends from the insertion portion 311 of the hinge supporter 310 toward the second plate 133. The first extension portion 322 may be formed to be inclined from the insertion portion 311 toward the plate coupling portion 130 of the reinforcing plate 123. A first curved portion may be formed between the insertion portion 311 and the first extension portion 322 in a curved shape to connect the insertion portion 311 and the first extension portion 322.

[0219] The second extension portion 323 may further extend in one direction from the first extension portion 322 toward the second plate 133 so as to overlap with the second plate extension portion 1331. A second curved portion may be formed between the first extension portion 322 and the second extension portion 323 in the curved shape to connect the first extension portion 322 and the second extension portion 323.
