[0029] Fifth, a plurality of support frames are disposed on one side of the main body. The plurality of support frames are coupled to and supported by the outer wall of the machine chamber. Accordingly, the plurality of support frames may support the main body.

[0030] Sixth, the hot line received in the machine chamber extends to bypass cycle components received in the machine chamber, namely the condenser, the compressor, the printed circuit board, and the support frames, thereby avoiding interference with the cycle components.Description of Drawings

Each of one 101a of the first panels 101a and 101b and / or the other one 101b of the first panels 101a and 101b forms another surface of the refrigerator. As an example of the another surface, the first panels 101a and 101b may form a left surface and a right surface of the refrigerator, respectively. One 101a of the first panels 101a and 101b and / or the other one 101b of the first panels 101a and 101b may be constituted by one of the first panels 101a and 101b and the other one 101b of the first panels 101a and 101b, which are disposed to face each other in a Y-axis direction. The fourth panel 104 forms yet another surface of the refrigerator. As the yet another surface, the fourth panel 104 may form a bottom surface or one surface.

[0074] A machine chamber 117 to be described later may be installed in the fourth panel 104. In the embodiment, the machine chamber 117 is illustrated, which is installed on one side of the fourth panel 104.

[0075] A vacuum adiabatic body may form at least one of the second panel 102, the third panel 103, one 101a of the first panels 101a and 101b and / or the other one 101b of the first panels 101a and 101b, and the fourth panel 104 or a portion of the at least one.

[0076] In the embodiment, the second panel 102, the third panel 103, one 101a of the first panels 101a and 101b, and / or the other one 101b of the first panels 101a and 101b are / is configured as the vacuum adiabatic body. However, the fourth panel 104 to be described later is illustrated, which is configured as a non-vacuum adiabatic body.

[0077] A storage chamber is formed inside the main body 100. The storage chamber includes a first storage chamber 106 and / or a second storage chamber 107. The first storage chamber 106 and the second storage chamber 107 may be disposed to be spaced apart from each other in a Z-axis direction or Y-axis direction of the main body 100.

[0078] The door includes a first storage chamber door 109 and / or a second storage chamber door 110.

[0079] The first storage chamber 106 and the second storage chamber 107 may be partitioned by a partition wall 108. The partition wall 108 may extend in one direction (e.g., horizontally) in the X-axis direction and the Y-axis direction from one surface of one 101a of the first panels 101a and 101b to one surface of the other one 101b of the first panels 101a and 101b.

[0080] When a height (vertical distance) between the third panel 103 and the fourth panel 104 is divided into three equal parts, the partition wall 108 may be located between 1 / 3 and 2 / 3 points of the height upward from the fourth panel 104. In the embodiment, the partition wall 108 is illustrated, which is disposed at approximately the 1 / 3 point of the height upward from the fourth panel 104.

[0081] The partition wall 108 may have a thickness in the Z-axis direction. The partition wall 108 may extend longer in the X-axis direction and the Y-axis direction than the thickness.

[0082] An opening part is formed on one surface of the main body 100. Through the opening part, storage articles to be stored in the storage chamber, for example, foods, are enabled to enter and exit the storage chamber. One surface of the door may be disposed to be connectable to one surface of the main body 100, and may seal the storage chamber using a gasket 112 to be described later.

[0083] The gasket 112 is disposed between one surface of the door and one surface of the main body 100. In the embodiment, the gasket 112 is illustrated, which is coupled to one surface of the door. A gasket coupling part 1121 is formed to protrude on one surface (e.g., inner surface) of the gasket 112 toward one surface of the door. The gasket coupling part is formed on one surface of the door to be recessed in a protruding direction of the gasket coupling part 1121. The gasket coupling part 1121 is coupled to a gasket coupling part. Accordingly, the gasket 112 may be coupled to one surface of the door.

[0084] The gasket 112 may be made of a material having elasticity, such as a rubber material, etc. The gasket 112 may maintain airtightness between the door and the main body 100 when the door is closed. However, a magnet 113 having magnetism may be embedded in one side (e.g., inner side) of the gasket 112. Accordingly, the magnetism of the magnet 113 embedded in the gasket 112 may be used to secure adhesive force between the door and the main body 100.

[0085] The refrigerator is configured to prevent a surface dew condensation phenomenon which occurs due to a temperature difference between an interior and an exterior of the refrigerator.

[0086] The hot line 114 is a component that dissipates heat. For example, the hot line 114 may be formed in a circular tube shape extending to allow a refrigerant to flow therein. The hot line 114 is connected to a condenser 119 to receive heat generated from the condenser 119 and dissipate heat. The hot line 114 transfers heat to a connection surface of the first storage chamber door 109 and / or the second storage chamber door 110, thereby preventing occurrence of the dew condensation phenomenon due to the temperature difference between the exterior and the interior of the refrigerator.

[0087] The second storage chamber 107 may have a greater temperature difference between the interior and the interior of the refrigerator than the first storage chamber 106. As a result, the hot line 114 may be applied to the second storage chamber 107 rather than the first storage chamber 106. In the embodiment, it is shown that the hot line 114 is applied to the second storage chamber 107.

[0088] The first storage chamber 106 may be formed on an inner side of each of a portion of the plurality of first panels 101a and 101b, a portion of the second panel 102, and the third panel 103, and one side of the partition wall 108. The second storage chamber 107 may be formed on an inner side of each of the other portion of the plurality of first panels 101a and 101b, and the other portion of the second panel 102, the other side of the partition wall 108, and one side (i.e., inner side) of the fourth panel 104.

[0089] A portion of the hot line 114 is disposed on one surface of the main body 100. A portion of the hot line 114 may be named a first hot line 115 for convenience of description. The first hot line 115 may be disposed on one surface of each of the other portion of the plurality of first panels 101a and 101b forming the second storage chamber 107, the partition wall 108, and / or the fourth panel 104. One surface of each of the other portion of the plurality of first panels 101a and 101b, the partition wall 108, and the fourth panel 104 faces one surface of the door. The first hot line 115 may be formed by bending one circular tube in a closed loop shape.

[0090] The first hot line 115 may be formed in an approximately rectangular shape. According to the embodiment, a first side 1151 (upstream side) of the first hot line 115 may extend in one direction along one surface of the fourth panel 104 from a central part of one surface of the fourth panel 104 based on a flow direction of a refrigerant (counterclockwise when viewed from the front), for example, in a +Y-axis direction (rightward direction).

[0091] A second side 1152 of the first hot line 115 may be bent and extend in the other one direction along one surface of one 101a of the plurality of first panels 101a and 101b from the first side 1151 of the first hot line 115 based on the flow direction of the refrigerant, for example, in a +Z-axis direction (upward direction).

[0092] A third side 1153 of the first hot line 115 may be bent and extend in another direction along one surface of the partition wall 108 from the second side 1152 of the first hot line 115 based on the flow direction of the refrigerant, for example, in a -Y-axis direction (leftward direction).

[0093] A fourth side 1154 of the first hot line 115 may be bent and extend in yet another direction along one surface of the other one 101b of the plurality of first panels 101a and 101b from the third side 1153 of the first hot line 115 based on the flow direction of the refrigerant, for example, in a - Z-axis direction (downward direction).

[0094] A fifth side 1155 (downstream side) of the first hot line 115 may be bent and extend in one direction along one surface of the partition wall 108 from a corner of one side of the fourth panel 104 to a central part of one surface of the fourth panel 104 based on the flow direction of the refrigerant, for example, in the +Y-axis direction (rightward direction).

[0095] The first side 1151 of the first hot line 115 and the fifth side 1155 of the first hot line 115 may be coupled to be connected by meeting each other. For example, the first side 1151 of the first hot line 115 and the fifth side 1155 of the first hot line 115 may be coupled by welding, etc.

[0096] However, the first side 1151 of the first hot line 115 and the fifth side 1155 of the first hot line 115 may be coupled while being separated from each other. For example, the first side 1151 of the first hot line 115 and the fifth side 1155 of the first hot line 115 are located at both ends of the first hot line 115 having the closed loop shape. The refrigerant flowing along the first hot line 115 may move counterclockwise from the first side 1151 of the first hot line 115 to the fifth side 1155 of the first hot line 115.

[0097] The first hot line 115 may be coupled to one side (e.g., inner side) of a cover 142 so as to be covered by the cover 142 to be described later (also referred to as a front decoration member).

[0115] The condenser 119 and the compressor 118 are coupled to the fourth cover 1174. The fourth cover 1174 may be named a base cover in that the refrigeration cycle apparatus received inside the machine chamber 117 is coupled thereto.

[0116] The condenser 119 and the first duct 124 may be located in a central part between the second cover 1172 and the third cover 1173. The compressor 118 and the second duct 125 may be located in a central part between the second cover 1172 and the third cover 1173. An interval between the condenser 119 and the first duct 124, and the second cover 1172 may be the same as an interval between the condenser 119 and the first duct 124, and the third cover 1173. An interval between the compressor 118 and the second duct 125, and the second cover 1172 may be the same as an interval between the compressor 118 and the second duct 125, and the third cover 1173.

[0117] The condenser 119 may be disposed close to the first covers 1171a and 1171b. The compressor 118 may be disposed close to the second cover 1172.

[0118] A dryer 121 may be disposed between the second cover 1172 and the first duct 124. The dryer 121 is configured to dry a refrigerant. The dryer 121 is formed in a cylindrical shape. The dryer 121 may extend in one direction.

[0119] One side of the dryer 121 is disposed to be spaced apart from the second cover 1172. The other side of the dryer 121 is disposed to be spaced apart from the first duct 124. An interval between one side of the dryer 121 and the second cover 1172 may be smaller than an interval between the other side of the dryer 121 and the first duct 124.

[0120] A drain 128 may be disposed between the second cover 1172 and the cooling fan 123. The drain 128 may extend in the Z-axis direction. The drain 128 may be disposed at one side of the evaporator. As an example of the one side, the drain 128 may extend downward. The evaporator and the drain 128 may be disposed to overlap in the Z-axis direction.

[0121] One side of the drain 128 is connected to be in communication with a drain pipe of the evaporator. The other side of the drain 128 is connected to be in communication with the outside. The other side of the drain 128 may be formed to pass through the fourth cover 1174. Accordingly, defrost water and the like generated in the evaporator may be discharged to the outside through the drain 128.

[0122] A three-way valve 122 may be disposed between the second cover 1172 and the second duct 125. The three-way valve 122 may be controlled by receiving a signal from a control unit that controls an overall operation of the refrigeration cycle apparatus. The three-way valve 122 is configured to change a flow path of the refrigerant or switch a flow direction of the refrigerant according to a control signal.

[0123] One side of the three-way valve 122 is disposed adjacent to the second cover 1172. The other side of the three-way valve 122 is disposed to be spaced apart from the second duct 125.

[0124] The expander 120 may be disposed between the second cover 1172 and the second duct 125. The expander 120 may be provided as a capillary tube. The capillary tube is formed in a circular tubular shape having a small diameter. For example, the diameter of the capillary tube is formed smaller than a diameter of a cycle pipe, for instance, a refrigerant pipe connecting the dryer 121 and the three-way valve 122. Accordingly, the capillary tube may expand the refrigerant. The capillary tube may be comprised of at least two tubes. Accordingly, the capillary tube may increase heat exchange efficiency.

[0125] One side of the capillary tube is disposed adjacent to the second cover 1172. The other side of the capillary tube is disposed to be spaced apart from the second duct 125.

[0126] The printed circuit board 130 may be disposed between the third cover 1173 and the second duct 125. Electronic components for implementing a control unit responsible for overall control of the refrigerator may be coupled to the printed circuit board 130.

[0127] The printed circuit board 130 is formed in a rectangular plate shape. The printed circuit board 130 is disposed in one direction (e.g., horizontally) on the fourth cover 1174. One side of the printed circuit board 130 is disposed adjacent to the third cover 1173. The other side of the printed circuit board 130 may be disposed to be spaced apart from the second duct 125.

The third cover 1173 may be detachably coupled to the machine chamber 117 when forming one surface (e.g., front surface) of the machine chamber 117. Accordingly, since the third cover 1173 is disposed at a front of the machine chamber 117, there is an advantage that it is easy for an operator to perform maintenance such as failure repair of the printed circuit board 130.

[0129] A harness 131 may be disposed between the other one 1171b of the plurality of first covers 1171a and 1171b and the compressor 118. The harness 131 refers to a bundle of electrical wires for applying power to electrical components of the refrigerator and signal lines for transmitting and receiving signals.

[0130] One side of the harness 131 is electrically connected to the printed circuit board 130. The other side of the harness 131 may be electrically connected to electrical components such as a motor, etc. The harness 131 may extend along one surface of the other one 1171b of the first covers 1171a and 1171b. The harness 131 extends to bypass the compressor 118.

[0131] The second hot line 116 is configured to bypass cycle components received inside the machine chamber 117, for example, the condenser 119, the compressor 118, the printed circuit board 130, etc.

[0132] As described above, the first part 1161 of the second hot line 116 and the second part 1162 of the second hot line 116 are connected to the first hot line 115, but are disposed to be spaced apart from each other. Through this, there is an advantage of easily avoiding interference between the hot line 114 and the cycle components. In addition, there is an advantage of easy coupling between a cover 142 to be described later and the hot line 114.

[0133] A portion of the first part 1161 of the second hot line 116 extends to pass through a portion of the first duct 124 at an outlet of the condenser 119.

[0134] A portion of the first part 1161 of the second hot line 116 may extend in parallel to be spaced apart from one 1171a of the plurality of first covers 1171a and 1171b at a predetermined interval in one direction. A portion of the first part 1161 of the second hot line 116 may be disposed to be spaced apart from the cooling fan 123 at a predetermined interval in one direction. An interval between a portion of the first part 1161 of the second hot line 116 and the one 1171a of the first covers 1171a and 1171b is smaller than an interval between a portion of the first part 1161 of the second hot line 116 and the cooling fan 123. Accordingly, the first part 1161 of the second hot line 116 easily avoids interference with components such as the condenser 119 and the cooling fan 123.

[0135] A portion of the first part 1161 of the second hot line 116 may be disposed adjacent to the fourth cover 1174. Through this, it is easy to avoid interference with the components such as the condenser 119 and the cooling fan 123.

[0136] A portion of the first part 1161 of the second hot line 116 may be disposed adjacent to the third cover 1173. This facilitates the connection between a portion of the first part 1161 of the second hot line 116 and the first side 1151 of the first hot line 115. The hot line 114 and the cover 142 are easily coupled.

[0137] A portion of the first part 1161 of the second hot line 116 is formed to be inclined with respect to the third cover 1173. For example, a portion of the first part 1161 of the second hot line 116 may extend in a first direction along the fourth cover 1174, and the other portion of the first part 1161 of the second hot line 116 may extend to be bent in a second direction different from the first direction along the third cover 1173. At this time, an inclined portion of the first part 1161 of the second hot line 116 easily avoids interference with other cycle components, for example, the printed circuit board 130, etc.

[0138] A portion of the second part 1162 of the second hot line 116 may extend from the fifth side 1155 of the first hot line 115 toward the expander 120. A portion of the second part 1162 of the second hot line 116 extends to pass through a portion of the first duct 124.

A portion of the second part 1162 of the second hot line 116 may be disposed to be spaced apart from a portion of the first part 1161 of the second hot line 116 at a predetermined interval in one direction. An interval between a portion of the second part 1161 of the second hot line 116 and one 1171a of the first covers 1171a and 1171b is smaller than an interval between a portion of the second part 1162 of the second hot line 116 and a portion of the first part 1161 of the second hot line 116. Accordingly, the second part 1162 of the second hot line 116 easily avoids interference with the components such as the condenser 119 and the cooling fan 123. The second part 1162 of the second hot line 116 is disposed to be spaced apart from the first covers 1171a and 1171b, thereby minimizing leakage of heat generated from the second hot line 116. On the other hand, a portion of the first part 1161 of the second hot line 116 may be disposed to be connected to a portion of an outer wall of the machine chamber 117 for heat dissipation. The portion of the first part 1161 of the second hot line 116 may be connected to the third cover 1173 as an example of the outer wall.

[0140] A portion of the second part 1162 of the second hot line 116 may be disposed adjacent to the fourth cover 1174. Through this, it is easy to avoid interference with the components such as the condenser 119 and the cooling fan 123.

[0141] A portion of the second part 1162 of the second hot line 116 may be disposed adjacent to the third cover 1173. This facilitates the connection between a portion of the first part 1162 of the second hot line 116 and the fifth side 1155 of the first hot line 115.

Here, an example of one surface of the fourth panel 104 may mean a front surface of the fourth panel 104. An example of one side of the cover 142 may mean a central part of the cover 142. The withdrawal part 1451 may be formed to pass through one side of the cover 142. The withdrawal part 1451 may be connected to be in communication with the machine chamber 117.

[0143] Based on the flow direction of the refrigerant flowing along the hot line 114, the downstream side of the first part 1161 of the second hot line 116 may be withdrawn from the machine chamber 117 through the withdrawal part 1451 and connected to the upstream side of the first side 1151 of the first hot line 115.

[0148] The downstream side of the first part 1161 of the second hot line 116 and the upstream side of the second part 1162 of the second hot line 116 are disposed adjacent to each other in the withdrawal part 1451, which is one side of the cover 142 extending to cover one surface of the fourth panel 104.

[0149] Accordingly, a portion of the hot line 114 withdrawn from the machine chamber 117 to one surface of the main body 100 may be easily coupled through the withdrawal part 1451 of the cover 142.

[0150] A portion of the second part 1162 of the second hot line 116 is formed to be inclined with respect to the third cover 1173.

The first wall 1461 is disposed toward one side (e.g., outer side) of the second plates 133a and 133b. The first wall 1461 may be coplanar with the second plates 133a and 133b.

[0186] A bent part 1462 may be formed on an end portion of the first wall 1461. The bent part 1462 may improve the strength of the line receptacle 146. The bent part 1462 is bent in a direction which is the same as a bending direction of the bent part 134 on the first wall 1461 to be connected to the first hot line 115. The bent part 1462 is formed to be shorter than the bent part 134. Accordingly, the bent part 1462 may restrict movement of the first hot line 115.

[0187] The second wall 1463 is disposed toward the inner side of the second plates 133a and 133b. The second wall 1463 may be formed to have a longer protruding length than the first wall 1461. A second coupling part 1464 is provided at an end portion of the second wall 1463. The second coupling part 1464 may be formed to protrude in the form of a coupling groove, a hook, or a protrusion. In the embodiment, the second coupling part 1464 is shown which is formed in the hook form.

[0188] A receiving hole may be formed to penetrate in one direction between the first wall 1461 and the second wall 1463 so that the hot line 114 may be received. The receiving hole faces the bent part 134. When the cover 142 is coupled to one surface of the main body 100, the receiving hole may be covered by the bent part 134.

[0189] A slope part 1466 may be formed at a corner where the first cover 142a and the second cover 142b meet. The slope part 1466 may prevent interference with the insulating block 141 provided on one side (e.g., inner side) of the door when the door is opened and closed.

[0190] The cover 142 may couple a magnet 147 to secure adhesive force between the main body 100 and the door when the door is closed. The magnet 147 may be disposed on one surface (e.g., inner surface) of the second cover 142b. The magnet 147 may be coupled to one side (e.g., inner side) of the cover 142 by various coupling means such as adhesion, hook coupling, coupling grooves, or coupling protrusions. Accordingly, the magnet 147 may provide the adhesive force between the door and the main body 100 when the door is closed by magnetic interaction with the magnet 113 embedded in the gasket 112 of the door, that is, by pulling the door with attractive force.

[0191] In the following description, the hot line 114 means the first hot line 115 disposed on one surface of the main body 100.

[0192] FIG. 17 is a conceptual view illustrating the hot line 114 coupled to a cover 200, and connected to one side (e.g., inner side) of the bent part 134 of the second plates 133a and 133b according to another embodiment of the present disclosure.

[0193] The embodiment differs from the embodiment of FIG. 16 in that a line receptacle 205 is manufactured separately from the cover 200 and is coupled to the cover 200, and the hot line 114 is disposed on one side (e.g., inner side) of the bent part 134.

[0194] The hot line 114 is disposed so as to be connected to one surface (e.g., inner surface) of the bent part 134. Accordingly, the hot line 114 may transfer heat to the second plates 133a and 133b through the bent part 134, thereby preventing the surface condensation phenomenon of the refrigerator.

[0195] An outer casing 140 may be disposed on one surface (e.g., outer surface) of the second plates 133a and 133b. The outer casing 140 may extend from the first panels 101a and 101b to the second panel 102. Accordingly, the outer casing 140 increases the strength of the second plates 133a and 133b, thereby preventing a buckling phenomenon (so called buckling) of the second plates 133a and 133b during air exhaust of the vacuum space.

[0196] An inner casing 139 may be disposed on an inner surface or outer surface of the first plates 132a and 132b. Here, the outer surface is a surface facing a first space formed on one side (e.g., inner side) of the main body 100. The inner casing 139 may extend from the first panels 101a and 101b to the second panel 102. Accordingly, the inner casing 139 increases the strength of the first plates 132a and 132b, thereby preventing the buckling phenomenon of the first plates 132a and 132b during the air exhaust of the vacuum space. When the insulating material is filled in one surface (e.g., outer surface) of the first plates 132a and 132b, the inner casing 139 may be easily filled with the insulating material even without the drawer guide 137.

[0197] The line receptacle 205 is received on one side (e.g., inner side) of the cover 200. The line receptacle 205 may be coupled to one side (e.g., inner side) of the cover 200. One side of the line receptacle 205 may be coupled to one surface (e.g., inner surface) of the first cover 142a. The other side of the line receptacle 205 may be coupled to one surface (e.g., inner surface) of the second plates 133a and 133b.

[0198] The other side of the line receptacle 205 includes a first support part 206. The first support part 206 is formed to protrude from the other side of the line receptacle 205 toward the side plates 135a and 135b in a first direction. Here, an example of the first direction may mean an X-axis direction. Accordingly, the first support part 206 is in close contact with one side of the hot line 114, thereby restricting the hot line 114 from moving in a second direction different from the first direction. Here, an example of the second direction may mean a Y-axis direction.

[0199] The other side of the line receptacle 205 includes a second support part 207. The second support part 207 is formed to protrude from the first support part 206 toward the second plates 133a and 133b in the second direction different from the first direction. Accordingly, the second support part 207 is in close contact with one side different from the one side of the hot line 114, thereby restricting the hot line 114 from moving in the first direction.

[0200] The other side of the line receptacle 205 includes a third support part 209. The third support part 209 is formed to protrude from the second support part 207 toward the side plates 135a and 135b in the first direction. A protruding length of the third support part 209 is formed such that the third support part 209 is connected to a portion of the side plates 135a and 135b. The third support part 209 may be in close contact with each of one surface (e.g., inner surface) of the second plates 133a and 133b and one surface (e.g., outer surface) of the side plates 135a and 135b. Accordingly, a portion of the line receptacle 205 is in close contact with corners where the side plates 135a and 135b and the second plates 133a and 133b meet, and as a result, the vacuum adiabatic body and the line receptacle 205 may reinforce mutual support force.

[0201] A coupling hole 208 may be formed to pass through one side of the line receptacle 205 in one direction. Here, one direction may be an X-axis direction. The coupling hole 208 may be formed in a circular shape. The shape of the coupling hole 208 is not limited thereto and may be formed in various shapes such as a rectangular shape, etc.

[0202] A coupling protrusion 203 may be provided on one side (e.g., inner side) of the cover 200. The coupling protrusion 203 is formed to protrude from one surface (e.g., inner surface) of the second cover 142b toward the coupling hole 208 of the line receptacle 205. The coupling protrusion 203 may be coupled by passing through the coupling hole 208. The coupling protrusion 203 and the coupling hole 208 may be coupled by press-fit.

[0203] A protrusion length of the coupling protrusion 203 is formed to be connectable to a side corner of the drawer guide 137 that meets the first plates 132a and 132b. One surface of a lengthwise end portion of the coupling protrusion 203 may be formed to be connected to corners where a portion of the side surface of the drawer guide 137, the first plates 132a and 132b, and the side plates 135a and 135b are connected. Accordingly, mutual support force between the cover 200 and the vacuum adiabatic body may be strengthened.

[0204] A portion of the line receptacle 205 may be disposed to overlap with the bent part 134 on one side (e.g., inner side) of the bent part 134. The other portion of the line receptacle 205 may be disposed not to overlap with the bent part 134.

[0205] One side of the first cover 142a may adhere or be coupled to the drawer guide 137. In the embodiment, one side of the first cover 142a and a side corner of the drawer guide 137 are in close contact with each other and adhere to each other.

[0206] A plurality of protrusion parts 204 may be formed on one surface (e.g., inner surface) of the second cover 142b. At least two first protrusion parts 204 of the plurality of protrusion parts 204 are configured to support the other portion of the line receptacle 205. Here, the other portion of the line receptacle 205 extends to protrude from one surface (e.g., inner surface) of the bent part 134 toward the first cover 142a. Accordingly, there is an advantage in that support force for the other portion of the line receptacle 205 that does not overlap with the bent part 134 may be secured, and the line receptacle 205 and the cover 200 are easily coupled.

[0207] At least two other second protrusion parts 204 among the plurality of protrusion parts 204 are formed to protrude from the second cover 142b toward the bending part 1401 of the outer casing 140. The plurality of second protrusion parts 204 are disposed to be connected to the bending part 1401 of the outer casing 140. The magnet 147 may be coupled between the first protrusion part 204 and the second protrusion part 204.

[0208] Since other components are the same as or similar to those in the embodiments of FIGS. 1 to 16 described above, redundant description will be omitted.

[0209] FIG. 18 illustrates a line receptacle 303 and a bent part 301 coupled to each other according to another embodiment of the present disclosure.

[0210] The embodiment is different from the embodiment of FIG. 17 described above in a coupling structure of the cover 300 and the bent part 301.

[0211] The line receptacle 303 is disposed on one side (e.g., inner side) of the bent part 301. A first support part 304 and a second support part 305 of the line receptacle 303 are configured to receive the hot line 114. The first support part 304 of the line receptacle 303 extends in a first direction. Here, an example of the first direction may mean an X-axis direction. The first support part 304 faces the second plates 133a and 133b with the hot line 114 interposed therebetween. The first support part 304 and the second plates 133a and 133b are disposed to overlap in a Y-axis direction to be described later. The first support part 304 and the second plates 133a and 133b may restrict the hot line 114 from moving in the Y-axis direction.

[0212] The second support part 305 of the line receptacle 303 extends from the first support part 304 in a second direction different from the first direction. Here, an example of the second direction may mean the Y-axis direction. The second support part 305 faces the bent part 301 with the hot line 114 interposed therebetween. The second support part 305 and the bent part 301 are disposed to overlap in the X-axis direction. The second support part 305 and the bent part 301 may restrict the hot line 114 from moving in the X-axis direction.

[0213] A coupling hole is formed to pass through the bent part 301. A coupler such as a screw, etc., may pass through the coupling hole and be coupled to the line receptacle 303 to be described later.

[0214] A boss part 306 may be provided on the other side of the line receptacle 303. The boss part 306 is formed to protrude from the other side of the line receptacle 303 toward the side plates 135a and 135b in a first direction. Here, an example of the first direction may mean an X-axis direction.

[0215] A female thread part may be formed on one side (e.g., inner side) of the boss part 306. The female thread part is coupled to the screw. Accordingly, by coupling the coupler such as the screw, etc., to the boss part 306, the bent part 301 and the line receptacle 303 may be coupled to each other. The cover 300 may be coupled to the bent part 300 through the line receptacle 303.

[0216] Since other components are the same as or similar to those in the embodiment of FIG. 17 described above, redundant description will be omitted.

[0217] FIG. 19 is a conceptual view illustrating a line receptacle 403 and a bent part 401 coupled to each other according to yet another embodiment of the present disclosure.

[0218] The embodiment is different from the embodiment of FIG. 16 described above in that the line receptacle 403 and a cover 412 are manufactured separately from each other, and the line receptacle 403 and the bent part 401 are coupled to each other.

[0219] The embodiment is different from the embodiments of FIGS. 16 to 18 described above in that the hot line 114 is not connected to the bent part 401.

[0220] A portion of the bent part 401 does not overlap with a bending part 411 of an outer casing 410 and further extends to protrude in a second direction so as to overlap with a portion of the line receptacle 403. Here, an example of the second direction may mean a Y-axis direction. A length of the bent part 401 may be formed in a ratio greater than 1 / 2 and smaller than 1 of the side length of the vacuum space. A coupling hole 402 may be formed to pass through the bent part 401 in a first direction different from the second direction. In the line receptacle 403, a coupling protrusion 405 is formed to protrude toward the coupling hole 402. The coupling protrusion 405 may be coupled to the bent part 401 by passing through the coupling hole 402. The coupling protrusion 405 and the bent part 401 may be coupled to each other through the coupling hole 402 by press-fit.

[0221] The line receptacle 403 is disposed on one side (e.g., outer side) of the bent part 401.

[0222] One side of a first cover 413 may be coupled to a drawer guide 416. A coupling protrusion 414 is formed to protrude on one side of the first cover 413. A protrusion receiving groove 417 may be formed to be recessed on one side of the drawer guide 415 so as to receive the coupling protrusion 414. The coupling protrusion 414 and the protrusion receiving groove 417 may be formed to have corresponding shapes and be fitted together. The coupling protrusion 414 and the protrusion receiving groove 417 may be coupled to each other by press-fit.

[0223] The hot line 114 may be coupled to one side of the line receptacle 403. A magnet 147 may be coupled to the other side of the line receptacle 403. One side of the line receptacle 403 is disposed to be connected to the bent part 401 of the second plates 133a and 133b. The other side of the line receptacle 403 is disposed to be connected to the bending part 411 of the outer casing 410.

[0224] On the other side surface of the line receptacle 403 facing an opposite direction to the coupling protrusion 405, at least three receiving walls are formed to protrude toward one side (e.g., outer side) of the bent part 401. A first receiving wall 406 among a plurality of receiving walls faces the first cover 413. A second receiving wall 407 among the plurality of receiving walls faces one side (e.g., outer side) of the second plates 133a and 133b. A third receiving wall 408 may be formed to protrude between the first receiving wall 406 and the second receiving wall 407.

[0225] A space that may receive the hot line 114 is formed between the second receiving wall 407 and the third receiving wall 408. A space that may receive a magnet 408 is formed between the third receiving wall 408 and the first receiving wall 406. The first receiving wall 406 may be connected to one surface of the second cover 415.

[0226] A first receiving hole is formed between the second receiving wall 407 and the third receiving wall 408 toward one side (e.g., outer side) of the bent part 401. The hot line 114 may be received and coupled through the first receiving hole.

[0227] A second receiving hole is formed between the third receiving wall 408 and the first receiving wall 406 toward one side (e.g., outer side) of the bent part 401. The magnet 408 may be received and coupled through the second receiving hole.

[0228] The second cover 415 may extend from one side of the first cover 413 to cover the first receiving hole and the second receiving hole. One side of the second cover 415 may be provided with a bending part 411 to cover the second receiving wall 407. The bending part 411 may be disposed to overlap with the second receiving wall 407 in one direction. Here, an example of one direction may mean a Y-axis direction.

[0229] One surface (e.g., inner surface) of the bending part 411 may be connected to one surface of the second receiving wall 407. The other surface (e.g., outer surface) of the bending part 411 may form the same plane as the second plates 133a and 133b or the outer casing 410.

[0230] One surface of the line receptacle 403 may be connected to the outer casing 410 and the bent part 401.

[0231] One surface of the line receptacle 403 may be disposed between the second cover 415 and the outer casing 410. One surface of the line receptacle 403 may be disposed between the second cover 415 and the bent part 401. Accordingly, the hot line 114 is not connected to the outer casing 410 and the bent part 401 by one surface of the line receptacle 403. When the hot line 114 is connected to the outer casing 410 or the bent part 401, an anti-dew condensation effect may be enhanced. On the other hand, heat provided from the condenser 119 is transferred through the hot line 114 to the outer casing 410 or the bent part 401, and as a result, heat loss may be increased.

[0232] When the hot line 114 is not connected to the outer casing 410 or the bent part 401, the anti-dew condensation effect may be lowered. On the other hand, heat loss provided from the condenser 119 may be reduced.

[0233] Accordingly, the line receptacle 403 and the cover 412 cover the hot line 114 and the magnet 408, thereby optimizing thicknesses of the line receptacle 403 and the cover 412.

[0234] Since other components are the same as or similar to those in the embodiments of FIGS. 1 to 18, redundant description will be omitted.

[0235] FIG. 20 is a conceptual view illustrating a coupling structure of the bent part 401 and a cover 500 according to yet another embodiment of the present disclosure.

[0236] A plurality of protruding walls are provided on one surface (e.g., inner surface) of a second cover 503. A first protruding wall 504 among the plurality of protruding walls is formed to protrude in one direction toward the side plates 135a and 135b. A second protruding wall 506 among the plurality of protruding walls faces one side (e.g., outer side) of the outer casing 410. A length of the first protruding wall 504 protruding from one surface (e.g., inner surface) of the second cover 503 may be formed longer than a length of the second protruding wall 506 protruding from one surface (e.g., inner surface) of the second cover 503. A coupling groove 505 is formed on one side (e.g., inner side) of the first protruding wall 504.

[0237] The coupling groove 505 is configured to receive one side of the bent part 401. One side of the bent part 401 may be coupled to the coupling groove 505. A coupling part 502 is formed on one side of the first cover 413 to protrude toward a drawer guide 508. A coupling groove 509 may be formed to be recessed on one side of the drawer guide 508 in a protruding direction of the coupling part 502.

[0238] A hot line coupling part 511 and a magnet coupling part 511 may be provided between the plurality of protruding walls. A coupling protrusion 507 may be formed to protrude between the hot line coupling part 511 and the magnet coupling part 511. The coupling protrusion 507 may be coupled in close contact with one side of the hot line 114.

[0239] Since other components are the same as or similar to those in the embodiments of FIGS. 1 to 19 described above, redundant description will be omitted.

[0240] FIG. 21 is a conceptual view illustrating a cover 600 and an insulating material coupled to a vacuum adiabatic body according to yet another embodiment of the present disclosure.

[0241] The embodiment is different from the embodiments of FIGS. 1 to 20 described above in that the hot line 114 is not coupled to the cover 600.

[0242] A temperature difference between an inside and an outside of the first storage chamber 106 is relatively smaller than a temperature difference between an inside and an outside of the second storage chamber 107.

[0243] As a result, the hot line 114 may be used mainly in the second storage chamber 107 and may be not coupled to the first storage chamber 106. The hot line 114 may be disposed on one surface of the main body 100 to cover an outer circumference of the second storage chamber 107. In the case of the first storage chamber 106, the drawer guide 508 may not be coupled to one surface (e.g., inner surface) of the first panels 101a and 101b.

[0244] An inner casing 139 may not extend from the first plates 132a and 132b of the first panels 101a and 101b to the second panel 102. A first insulating material 603 may extend to cover only a portion of the first plates 132a and 132b where the inner casing 139 does not extend. A coupling part 602 may be provided on one side of the first cover 413. The coupling part 602 may be directly coupled to the first plates 132a and 132b of the vacuum adiabatic body by welding, etc., due to absence (non-coupling) of the drawer guide 508.

[0245] Since other components are the same as or similar to those in the embodiments of FIGS. 1 to 16 described above, redundant description will be omitted.
