[0026] Invention Effects

[0027] According to embodiments of the present invention, the following effects can be achieved.

[0028] First, the hot wires connect to the condenser and expander. The hot wires can be divided into a first hot wire section, a second hot wire section, and a third hot wire section based on the refrigerant flow direction. The first and third hot wire sections are housed in the machine compartment. The second hot wire section is formed as a closed loop.

The hot wires prevent condensation on the surfaces that form the exterior of the refrigerator.

[0029] Secondly, the curved portion formed on one side of the main body can bend one corner of the second plate of the insulation body to ensure the strength of the insulation body. As a result, during the manufacturing of the vacuum insulation panel, it is possible to prevent the shape distortion of the panel caused by vacuum and high-temperature exhaust.

[0030] Third, the heat wire can be connected to the curved portion formed on one side of the body, thereby transferring heat to the outer shell that forms the appearance of the refrigerator or the second plate of the vacuum insulation. In addition, the cover member can be joined to one side of the body using the curved portion.

[0031] Fourth, a portion of the hot wire can be housed within the machine room to prevent damage from exposure. Another portion of the hot wire can be connected to a section of the outer wall of the metal machine room to provide additional heat dissipation.

[0032] Fifth, a plurality of support frames are arranged on one side of the main body. The plurality of support frames are combined and supported on the outer wall of the machine room. Thus, the plurality of support frames can support the main body.

[0033] Sixth, the hot wires housed in the machine compartment can be extended to bypass the condenser, compressor, printed circuit board, and support frame, which are circulation components housed in the machine compartment, thereby avoiding interference with the circulation components.

[0094] The refrigerator according to the present invention includes a body 100 and a door (not shown).

[0095] At least two panels of the main body 100 form the appearance of the refrigerator. The main body 100 may be composed of a plurality of panels.

[0096] For example, the panels constituting the body 100 include one of the first panels 101a and 101b, another first panel 101b, a second panel 102, a third panel 103, and / or a fourth panel 104. The second panel 102 forms one side of the refrigerator. As an example of this side, it can form the back of the refrigerator. The third panel 103 forms the other side of the refrigerator. As an example of this other side, it can form the top surface of the refrigerator. One of the first panels 101a and 101b, and / or the other first panel 101b, respectively forms another side of the refrigerator. As an example of this other side, it can form the left and right sides of the refrigerator. One of the first panels 101a and / or the other of the first panels 101a and 101b may be composed of one of the first panels 101a and 101b and the other of the first panels 101a and 101b arranged opposite each other in the Y-axis direction. A fourth panel 104 may form another side of the refrigerator. As an example of said other side, the fourth panel 104 may form the bottom surface or one side.

[0097] The machine room 117, which will be described later, can be provided on the fourth panel 104. In this embodiment, a state in which the machine room 117 is provided on one side of the fourth panel 104 is shown.

[0098] The vacuum insulation body can form at least one or a portion of at least one of the second panel 102, the third panel 103, the first panel 101a, 101b, the first panel 101a and / or the other first panel 101b, and the fourth panel 104.

[0099] In this embodiment, one of the first panels 101a and / or the other of the first panels 101a and 101b, the second panel 102, the third panel 103, and the first panels 101a and 101b, is made of a vacuum insulation material. However, the fourth panel 104, described later, is shown as being made of a non-vacuum insulation material.

[0100] A storage chamber is formed inside the 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 arranged spaced apart in the Z-axis or Y-axis direction of the body 100.

[0101] The doors include a first storage room door 109 and / or a second storage room door 110.

[0102] The first storage chamber 106 and the second storage chamber 107 may be separated by a partition wall 108. The partition wall 108 may extend from one side of the first panel 101a to one side of the other first panel 101b along one of the X-axis and Y-axis directions (e.g., horizontally).

[0103] The partition wall 108 can be positioned between 1 / 3 and 2 / 3 of the height when the height (vertical distance) between the third panel 103 and the fourth panel 104 is divided into three equal parts, extending upwards from the fourth panel 104. In this embodiment, the partition wall 108 is shown positioned approximately at 1 / 3 of the height from the fourth panel 104 upwards.

[0104] The partition wall 108 may have a thickness in the Z-axis direction. The partition wall 108 may extend in the X-axis and Y-axis directions to be longer than the thickness.

[0105] An opening is formed on one side of the main body 100. Items to be stored in the storage room (e.g., food) can enter and exit the storage room through the opening. One side of the door can be configured to connect with one side of the main body 100, and the storage room can be sealed using the gasket 112 described later.

[0106] A gasket 112 is disposed between one side of the door and one side of the body 100. In this embodiment, the gasket 112 is shown in a state where it is engaged with one side of the door. A gasket engagement portion 1121 is formed protruding from one side (e.g., the inner side) of the gasket 112 toward the side of the door. A gasket engagement portion is formed recessed from one side of the door toward the protruding direction of the gasket engagement portion 1121. The gasket engagement portion 1121 engages with the gasket engagement portion. Thus, the gasket 112 can be engaged with one side of the door.

[0107] The gasket 112 can be made of an elastic material such as rubber. The gasket 112 can maintain an airtight seal between the door and the body 100 when the door is closed. However, a magnetic magnet 113 can be built into one side (e.g., the inside) of the gasket 112. Thus, the magnetism of the magnet 113 built into the gasket 112 can be used to ensure the tightness between the door and the body 100.

[0108] The refrigerator is designed to use a heat line 114 to prevent condensation on the surface caused by the temperature difference between the inside and outside of the refrigerator.

[0109] The heat wire 114 is a heat-dissipating component. For example, the heat wire 114 can be formed as an extended circular tube to allow refrigerant to flow inside. The heat wire 114 can be connected to the condenser 119 to receive and dissipate the heat generated in the condenser 119. The heat wire 114 transfers heat to the connection surface of the first storage compartment door 109 and / or the second storage compartment door 110, thereby preventing condensation caused by the temperature difference between the outside and inside of the refrigerator.

[0110] Compared to the first storage compartment 106, the temperature difference between the inside and outside of the second storage compartment 107 may be greater. Therefore, the heat wire 114 can be applied to the second storage compartment 107, compared to the first storage compartment 106. In this embodiment, the state of the heat wire 114 applied to the second storage compartment 107 is shown.

[0111] The first storage chamber 106 may be formed on a portion of a plurality of first panels 101a, 101b, a portion of the second panel 102, the inner side of the third panel 103, and one side of the partition wall 108. The second storage chamber 107 may be formed on another portion of the plurality of first panels 101a, 101b, another portion of the second panel 102, the other side of the partition wall 108, and one side (e.g., the inner side) of the fourth panel 104.

[0112] A portion of the heat wire 114 is disposed on one side of the main body 100. For ease of explanation, a portion of the heat wire 114 may be designated as the first heat wire 115. The first heat wire 115 may be disposed on another portion of the plurality of first panels 101a, 101b forming the second storage chamber 107, on one side of the partition wall 108 and / or the fourth panel 104. The other portion of the plurality of first panels 101a, 101b, the partition wall 108, and the fourth panel 104 each face the door. The first heat wire 115 may be formed by bending a circular tube into a closed loop shape.

[0113] The first hot wire 115 can be roughly rectangular. According to this embodiment, the first side 1151 (upstream side) of the first hot wire 115 can extend from the center of one side of the fourth panel 104 along one side of the fourth panel 104 with the refrigerant flow direction (counterclockwise when viewed from the front) as a reference. For example, it extends in the +Y axis direction (right side direction).

[0114] The second side 1152 of the first hot wire 115 can bend and extend from the first side 1151 of the first hot wire 115 along one of the first panels 101a and 101b in another direction, based on the direction of refrigerant flow. For example, it can bend and extend in the +Z axis (upward).

[0115] The third side 1153 of the first hot wire 115 can bend and extend in another direction from the second side 1152 of the first hot wire 115 along one side of the partition wall 108, based on the direction of refrigerant flow. For example, it can bend and extend in the -Y axis direction (left direction).

[0116] The fourth side 1154 of the first hot wire 115 can bend and extend in another direction from the third side 1153 of the first hot wire 115 along one of the plurality of first panels 101b 101a, 101b, based on the direction of refrigerant flow. For example, it can bend and extend in the -Z axis (downward).

[0117] The fifth side 1155 (downstream side) of the first hot line 115 can extend from one side corner of the fourth panel 104 along one side of the fourth panel 104 to the center of one side of the fourth panel 104, based on the flow direction of the refrigerant. For example, it can extend in the +Y axis direction (right direction) to the center of one side of the fourth panel 104.

[0118] The first side 1151 and the fifth side 1155 of the first hot wire 115 can be joined together to intersect and connect with each other. For example, the first side 1151 and the fifth side 1155 of the first hot wire 115 can be joined by welding or the like.

[0119] However, the first side 1151 and the fifth side 1155 of the first hot wire 115 are combined in a separate state. For example, the first side 1151 and the fifth side 1155 of the first hot wire 115 are located at the two ends of the first hot wire 115, which has a closed loop configuration. The refrigerant flowing along the first hot wire 115 can move from the first side 1151 of the first hot wire 115 in a counterclockwise direction towards the fifth side 1155 of the first hot wire 115.

[0120] The first hot line 115 can be combined with one side (e.g., the inside) of the cover member 142 in a manner that is covered by the cover member 142 (also known as the front trim) described later.

[0121] Another portion of the hot wire 114 is located inside the machine room 117. For ease of explanation, this other portion of the hot wire 114 may be referred to as the second hot wire 116.

[0122] The first portion 1161 of the second hot wire 116 can extend from the outlet of the condenser 119 (described later) toward one side of the machine room 117 (described later). Here, "one side of the machine room 117" as an example of "one side" can refer to the front of the machine room 117. The first portion 1161 of the second hot wire 116 is connected to the outlet of the condenser 119 and the first side 1151 of the first hot wire 115.

[0123] The second portion 1162 of the second hot wire 116 can extend from one side of the machine room 117 toward the expander 120, which will be described later. The second portion 1162 of the second hot wire 116 is connected to the fifth side 1155 of the first hot wire 115 and the expander 120.

[0124] The first portion 1161 and the second portion 1162 of the second hot wire 116 can be configured apart from each other. However, a portion of the first portion 1161 of the second hot wire 116 connected to the first side 1151 of the first hot wire 115 and a portion of the second portion 1162 of the second hot wire 116 connected to the fifth side 1155 of the first hot wire 115 can be configured adjacent to each other and combined.

[0125] The cover constituting the machine room 117 includes one of the first covers 1171a and 1171b, another first cover 1171b, a second cover 1172, a third cover 1173, and / or a fourth cover 1174. The second cover 1172 forms one side of the machine room 117. As an example of this side, it can form the back side of the machine room 117. The third cover 1173 forms another side of the machine room 117. As an example of this other side, it can form the front side of the machine room 117. One of the first covers 1171a and 1171b, and the other first cover 1171b, respectively form yet another side of the machine room 117. As an example of this yet another side, it can form the left and right sides of the machine room 117. One of the first covers 1171a and 1171b, and the other of the first covers 1171a and 1171b, can be arranged opposite each other in the Y-axis direction. In this embodiment, one of the first covers 1171a forms the left side of the machine room 117, and the other of the first covers 1171a and 1171b forms the right side of the machine room 117. A fourth cover 1174 forms another side of the machine room 117. As an example of the other side, the fourth cover 1174 can form the bottom surface or one side. The other side of the machine room 117 can be made open. Here, as an example of the other side, it can be the top surface of the machine room 117. The other side of the machine room 117 can be configured to be covered by a fourth panel 104. The fourth panel 104 is configured to separate the storage room of the body 100 and the machine room 117. The fourth panel 104 can separate the second storage room 107 and the machine room 117.

[0126] The fourth panel 104 can be supported in the machine room 117 by a plurality of support frames 148a, 148b. The support frames 148a, 148b can extend in one direction. Here, as an example of one direction, it can refer to the Y-axis direction. One side of the support frames 148a, 148b can be combined with one of the first covers 1171a of the plurality of first covers 1171a, 1171b, and the other side of the support frames 148a, 148b can be combined with another of the first covers 1171b of the plurality of first covers 1171a, 1171b.

[0127] One side of the fourth panel 104 can be combined with one side of one of the plurality of first covers 1171a, 1171b. Here, one example of one side of the fourth panel 104 can refer to the bottom surface of the fourth panel 104. One example of one side of the first covers 1171a, 1171b can refer to the upper side of the first covers 1171a, 1171b.

[0128] A plurality of support frames 148a, 148b may be constituted by a first support frame 148a and a second support frame 148b. The first support frame 148a is configured separately from the third cover 1173. The second support frame 148b is configured separately from the first support frame 148a in the X-axis direction. The second support frame 148b is configured separately from the second cover 1172.

[0129] The machine compartment 117 is formed to house part of a refrigeration cycle device, such as a compressor 118, a condenser 119, an expander 120, etc.

[0130] A condenser 119 is disposed on one side of the machine compartment 117. A compressor 118 is disposed on the other side of the machine compartment 117. The condenser 119 and the compressor 118 are arranged apart in one direction. A cooling fan 123 is disposed between the condenser 119 and the compressor 118. The cooling fan 123 is configured to cool the condenser 119 by means of airflow. The cooling fan 123 is configured to direct airflow in one direction within the machine compartment 117. The airflow of the cooling fan 123 can correspond to the arrangement direction of the condenser 119 and the compressor 118.

[0131] The condenser 119 can be arranged adjacent to one of the plurality of first covers 1171a and 1171b within the machine compartment 117. The compressor 118 can be arranged adjacent to another of the plurality of first covers 1171a and 1171b within the machine compartment 117.

[0132] One of the plurality of first covers 1171a and 1171b, first cover 1171a may have a plurality of intake ports 126 formed through one direction. Another of the plurality of first covers 1171a and 1171b, first cover 1171b may have a plurality of exhaust ports formed through one direction.

[0133] The cooling fan 123 may include a plurality of blades 1232 rotatably disposed inside the fan housing 1231 to guide airflow in one direction. The cooling fan 123 may draw in external air through the intake port 126. The cooling fan 123 may guide airflow toward the condenser 119. The cooling fan 123 may guide airflow toward the compressor 118. The cooling fan 123 may exhaust air passing through the condenser 119 and the compressor 118 to the outside through the exhaust port.

[0134] A plurality of pipes are arranged inside the machine room 117. The pipes effectively guide the airflow in one direction. Thus, the air circulating inside and outside the machine room 117 can effectively cool the condenser 119 and the like without dispersing. The plurality of pipes includes a first pipe 124 and a second pipe 125.

[0135] The first conduit 124 extends in one direction. The first conduit 124 forms an internal space that isolates the machine room 117 and the condenser 119. The first conduit 124 houses the condenser 119. Airflow can be formed inside the first conduit 124. One side of the first conduit 124 is connected in communication with the air intake 126 to surround the air intake 126. The other side of the first conduit 124 surrounds a portion of the cooling fan 123.

[0136] The second conduit 125 extends in one direction. The second conduit 125 forms an internal space that isolates the machine room 117 and the compressor 118. The second conduit 125 houses the compressor 118. Airflow can be formed inside the second conduit 125. One side of the second conduit 125 surrounds a portion of the cooling fan 123. The other side of the second conduit 125 surrounds and communicates with an exhaust port.

[0137] An intake port 126 may be formed in the center of one of the plurality of first covers 1171a and 1171b. An exhaust port may be formed in the center of another of the plurality of first covers 1171a and 1171b.

[0138] The condenser 119 and compressor 118 are combined with the fourth cover 1174. Since the refrigeration circulation device housed inside the machine compartment 117 is combined with the fourth cover 1174, the fourth cover 1174 can be referred to as the bottom cover.

[0139] The condenser 119 and the first pipe 124 can be located in the central portion between the second cover 1172 and the third cover 1173. The compressor 118 and the second pipe 125 can be located in the central portion between the second cover 1172 and the third cover 1173. The spacing formed by the condenser 119 and the first pipe 124 with the second cover 1172 can be the same as the spacing formed by the condenser 119 and the first pipe 124 with the third cover 1173. The spacing formed by the compressor 118 and the second pipe 125 with the second cover 1172 can be the same as the spacing formed by the compressor 118 and the second pipe 125 with the third cover 1173.

[0140] The condenser 119 can be configured close to the first covers 1171a, 1171b. The compressor 118 can be configured close to the second cover 1172.

[0141] A dryer 121 may be disposed between the second cover 1172 and the first pipe 124. The dryer 121 is configured to dry the refrigerant. The dryer 121 is cylindrical in shape. The dryer 121 may extend in one direction.

[0142] One side of the dryer 121 is disposed apart from the second cover 1172. The other side of the dryer 121 is disposed apart from the first pipe 124. The distance between one side of the dryer 121 and the second cover 1172 may be less than the distance between the other side of the dryer 121 and the first pipe 124.

[0143] A drain element 128 may be disposed between the second cover 1172 and the cooling fan 123. The drain element 128 may extend along the Z-axis. The drain element 128 may be disposed on one side of the evaporator. As an example of said side, it may extend downward. The evaporator and the drain element 128 may be disposed overlapping in the Z-axis direction.

[0144] One side of the drain element 128 is connected in communication with the drain pipe of the evaporator. The other side of the drain element 128 is connected in communication with the outside. The other side of the drain element 128 can be formed through the fourth cover 1174. Thus, defrost water and the like generated in the evaporator can be discharged to the outside through the drain element 128.

[0145] A three-way valve 122 may be disposed between the second cover 1172 and the second pipe 125. The three-way valve 122 can be controlled by receiving a signal from the control unit responsible for the overall control of the refrigeration cycle unit. The three-way valve 122 is configured to change the flow path of the refrigerant or change the flow direction of the refrigerant according to the control signal.

[0146] 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 separately from the second pipe 125.

[0147] An expander 120 may be disposed between the second cover 1172 and the second pipe 125. The expander 120 may be equipped as a capillary tube. The capillary tube is formed into a circular tube shape with a relatively small diameter. For example, the diameter of the capillary tube is formed to be smaller than that of the circulation piping, for example, smaller than the diameter of the refrigerant pipe connecting the dryer 121 and the three-way valve 122. Thus, the capillary tube can expand the refrigerant. There may be at least two capillary tubes. Thus, the capillary tube can improve the heat exchange efficiency.

[0148] One side of the capillary tube is disposed adjacent to the second cover 1172. The other side of the capillary tube is disposed apart from the second conduit 125.

[0149] A printed circuit board 130 may be disposed between the third cover 1173 and the second pipe 125. Electronic components for implementing the overall control of the refrigerator may be incorporated into the printed circuit board 130.

[0150] The printed circuit board 130 is formed in a rectangular board shape. The printed circuit board 130 is disposed on the fourth cover 1174 in one direction (e.g., horizontally). 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 adjacent to the second conduit 125.

[0151] The third cover 1173 is disposed on one side (e.g., the outer side) of the body 100. The third cover 1173 can be detachably attached to the machine room 117 while forming one side (e.g., the front) of the machine room 117. Thus, the third cover 1173 is disposed on the front side of the machine room 117, which has the advantage of making it easy for operators to perform maintenance such as fault repair of the printed circuit board 130.

[0152] A wiring harness 131 may be disposed between another first cover 1171b of the plurality of first covers 1171a, 1171b and the compressor 118. The wiring harness 131 refers to a bundle of wires for supplying power to the electrical components of the refrigerator and signal lines for transmitting and receiving signals.

[0153] One side of the wiring harness 131 is electrically connected to the printed circuit board 130. The other side of the wiring harness 131 can be electrically connected to electrical components such as a motor. The wiring harness 131 can extend along one side of the other of the first covers 1171a and 1171b. The wiring harness 131 extends to bypass the compressor 118.

[0154] The second hot wire 116 is configured to bypass circulating components housed inside the machine room 117, such as the condenser 119, compressor 118, printed circuit board 130, etc.

[0155] As described above, the first portion 1161 and the second portion 1162 of the second hot wire 116 are connected to or spaced apart from the first hot wire 115. This provides the advantage of easily avoiding interference between the hot wire 114 and the circulation component. Furthermore, it facilitates the connection between the cover member 142 (described later) and the hot wire 114.

[0156] A portion of the first section 1161 of the second hot line 116 extends from the outlet of the condenser 119 into a portion of the first conduit 124.

[0157] A portion of the first part 1161 of the second heat wire 116 may extend parallel to one of the first covers 1171a of the plurality of first covers 1171a, 1171b, separated by a predetermined interval in one direction. A portion of the first part 1161 of the second heat wire 116 may be configured to be separated from the cooling fan 123 by a predetermined interval in one direction. The interval between the portion of the first part 1161 of the second heat wire 116 and one of the first covers 1171a, 1171b is smaller than the interval between the portion of the first part 1161 of the second heat wire 116 and the cooling fan 123. Therefore, the first part 1161 of the second heat wire 116 easily avoids interference with components such as the condenser 119 and the cooling fan 123.

[0158] A portion of the first section 1161 of the second hot wire 116 can be configured adjacent to the fourth cover 1174. This easily avoids interference with components such as the condenser 119 and the cooling fan 123.

[0159] A portion of the first section 1161 of the second heating wire 116 can be configured adjacent to the third cover 1173. This facilitates the connection of the portion of the first section 1161 of the second heating wire 116 to the first side 1151 of the first heating wire 115. The connection between the heating wire 114 and the cover member 142 is also easy.

[0160] A portion of the first section 1161 of the second heat wire 116 is formed at an angle relative to the third cover 1173. For example, a portion of the first section 1161 of the second heat wire 116 may extend along the fourth cover 1174 in a first direction, and another portion of the first section 1161 of the second heat wire 116 may extend along the third cover 1173 in a curved second direction different from the first direction. In this case, the angled portion of the first section 1161 of the second heat wire 116 easily avoids interference with other circulating components (e.g., printed circuit board 130, etc.).

[0161] A portion of the second section 1162 of the second hot wire 116 may extend from the fifth side 1155 of the first hot wire 115 toward the expander 120. A portion of the second section 1162 of the second hot wire 116 extends to a portion of the first conduit 124.

[0162] A portion of the second part 1162 of the second heat wire 116 can extend parallel to one of the first covers 1171a (of the plurality of first covers 1171a, 1171b) in one direction, separated by a predetermined interval. A portion of the second part 1162 of the second heat wire 116 can be configured to be separated from a portion of the first part 1161 of the second heat wire 116 in one direction by a predetermined interval. The interval between the portion of the second part 1162 of the second heat wire 116 and one of the first covers 1171a (of the plurality of first covers 1171a, 1171b) is greater than the interval between the portion of the second part 1162 of the second heat wire 116 and the portion of the first part 1161 of the second heat wire 116. Therefore, the second part 1162 of the second heat wire 116 easily avoids interference with components such as the condenser 119 and the cooling fan 123. The second part 1162 of the second heat wire 116 can be arranged separately from the first covers 1171a, 1171b, thereby minimizing the leakage of heat generated in the second heat wire 116. Conversely, a portion of the first section 1161 of the second hot wire 116 can be configured to connect to a portion of the outer wall of the machine room 117 for heat dissipation. As an example of the outer wall, it can be connected to a third cover 1173.

[0163] A portion of the second section 1162 of the second hot wire 116 can be configured adjacent to the fourth cover 1174. This easily avoids interference with components such as the condenser 119 and the cooling fan 123.

[0164] A portion of the second section 1162 of the second hot wire 116 can be configured adjacent to the third cover 1173. This facilitates the connection of the portion of the second section 1162 of the second hot wire 116 to the fifth side 1155 of the first hot wire 115. The connection between the hot wire 114 and the cover member 142 is also easy.

[0165] A portion of the first section 1161 of the second hot wire 116 is led out from the machine chamber 117. A portion of the first section 1161 of the second hot wire 116 can be led out through the lead-out portion 1451 of the cover member 142. The lead-out portion 1451 can be provided on one side of the cover member 142 that covers one side of the fourth panel 104. Here, "one side of the fourth panel 104" can refer to the front of the fourth panel 104. "One side of the cover member 142" can refer to the central portion of the cover member 142. The lead-out portion 1451 can be formed to penetrate one side of the cover member 142. The lead-out portion 1451 can be connected in communication with the machine chamber 117.

[0166] Based on the flow direction of the refrigerant flowing along the hot wire 114, the downstream side of the first portion 1161 of the second hot wire 116 can be led out from the machine room 117 through the lead-out portion 1451 and connected to the upstream side of the first side 1151 of the first hot wire 115.

[0167] The downstream side of the first portion 1161 of the second hot wire 116 may extend along a first direction and bend to extend through the lead-out portion 1451 in a second direction different from the first direction, and may be connected to the upstream side of the first side 1151 of the first hot wire 115.

[0168] Based on the flow direction of the refrigerant flowing along the hot wire 114, the downstream side of the fifth side 1155 of the first hot wire 115 can be introduced into the machine room 117 through the lead-out part 1451 and connected to the upstream side of the second part 1162 of the second hot wire 116.

[0169] The downstream side of the fifth side 1155 of the first hot wire 115 may extend along the second direction and extend through the lead-out portion 1451 in a curved manner to a first direction different from the second direction, and may be connected to the upstream side of the second portion 1162 of the second hot wire 116.

[0170] The upstream side of the first side 1151 of the first hot wire 115 and the downstream side of the fifth side 1155 of the first hot wire 115 are arranged adjacent to each other on the side of the lead-out portion 1451, which is a cover member 142 extending to cover one side of the fourth panel 104.

[0171] The downstream side of the first portion 1161 of the second hot wire 116 and the upstream side of the second portion 1162 of the second hot wire 116 are arranged adjacent to each other on the side of the lead-out portion 1451, which is a cover member 142 extending to cover one side of the fourth panel 104.

[0172] Thus, a portion of the heat line 114, which is led out from the machine room 117 to one side of the body 100, can be easily connected via the lead-out portion 1451 of the cover member 142.

[0173] A portion of the second section 1162 of the second heat wire 116 is formed at an angle relative to the third cover 1173. For example, a portion of the second section 1162 of the second heat wire 116 may extend along the fourth cover 1174 in a first direction, and another portion of the second section 1162 of the second heat wire 116 may extend along the third cover 1173 in a curved second direction different from the first direction. In this case, the angled portion of the first section 1161 of the second heat wire 116 is prone to interference with other circulating components (e.g., printed circuit board 130, etc.).

[0174] A portion of the first part 1161 of the second hot line 116 and a portion of the second part 1162 of the second hot line 116 can be configured at the corner where one of the first covers 1171a and 1171b intersects with the third cover 1173.

[0175] A portion of the second part 1162 of the second hot wire 116 may extend along the second cover 1172 in one direction at a predetermined interval and be connected to one side of the dryer 121.

[0176] A portion of the second section 1162 of the second hot wire 116 may extend along the second cover 1172 in one direction at a predetermined interval and connect to the other side of the dryer 121 and the three-way valve 122. The three-way valve 122 may be connected to a capillary tube.

[0177] The first panels 101a and 101b are composed of a vacuum insulation body. Second panels 133a and 133b constituting the vacuum insulation body can extend along a first direction. Here, the first direction can be the X-axis direction. A bend 134 can be provided on one side of the second panels 133a and 133b. Here, the side can be a portion (e.g., the front end) of the second panels 133a and 133b facing an opening formed on one side of the body 100. The bend 134 is formed by bending from one side of the second panels 133a and 133b in a second direction different from the first direction. Here, the second direction can be the Y-axis direction.

[0178] According to this configuration, the bending portion 134 can improve the strength of the vacuum insulation panel, thus preventing the panel shape from being distorted by vacuum and high-temperature exhaust during the manufacturing of the vacuum insulation panel.

[0179] The bend 134 can be used in the conduction and connection cover member 142 of the heat line 114, which will be described later.

[0180] The bent portion 134 is disposed on one side (e.g., the outer side) of the sealing portion of the sealing second plates 133a, 133b and side plates 135a, 135b. The bent portion 134 can be bent into two layers at the ends of the second plates 133a, 133b.

[0181] The length of the curved portion 134 extending in the second direction can be made less than the side length of the vacuum space portion. The length of the curved portion 134 extending in the second direction can be made less than the interval between the second plates 133a, 133b and the first plates 132a, 132b. The length of the curved portion 134 is preferably about half the side length of the vacuum space portion.

[0182] The bent portion 134 is disposed spaced apart from the side plates 135a and 135b. The bent portion 134 may be disposed overlapping a portion of the side plates 135a and 135b in the X-axis direction.

[0183] Drawer guide 137 may be configured separately from the first panels 132a, 132b. Optionally, drawer guide 137 may be provided in the second storage compartment 107 instead of the first storage compartment 106. Drawer guide 137 may guide a drawer to be introduced into or drawn out from the interior of the body 100.

[0184] The drawer guide 137 can be formed from a plastic material that can be injection molded using a polymer resin with low thermal conductivity.

[0185] Optionally, a first heat insulation member 138a may be provided between the drawer guide 137 and the first plates 132a, 132b. The first heat insulation member 138a may be made of polyurethane foam. Thus, the first heat insulation member 138a can enhance the heat insulation performance of the vacuum insulation body that insulates against heat leakage between the outside and inside of the box. Optionally, even if the first heat insulation member 138a is not provided between the drawer guide 137 and the first plates 132a, 132b, the hollow space between the drawer guide 137 and the first plates 132a, 132b can still achieve the effect of heat insulation against heat leakage between the outside and inside of the box.

[0186] The first heat insulation element 138a can extend along the first plates 132a and 132b with reference to the corners of the first plates 132a and 132b that intersect with the side plates 135a and 135b.

[0187] An inner shell 139 may be provided between the first plates 132a and 132b and the first heat insulation member 138a. The inner shell 139 may be made of a metallic material. The inner shell 139 may strengthen the first plates 132a and 132b, which are thin plates, and prevent partial twisting of the first plates 132a and 132b.

[0188] A portion of the first plates 132a, 132b may be exempt from the inner housing 139. The first thermal insulation 138a may extend to a portion of the first plates 132a, 132b where the inner housing 139 is not applied.

[0189] Optionally, a second heat insulation member 138b may be provided between the bend 134 and the side plates 135a, 135b. The second heat insulation member 138b may be made of polyurethane foam. Thus, the second heat insulation member 138b can enhance the heat insulation performance of the vacuum insulation body that insulates against heat leakage between the outside and inside of the enclosure. Optionally, the second heat insulation member 138b may not be provided between the bend 134 and the side plates 135a, 135b.

[0190] The first heating wire 115 can be connected to the bending portion 134. The bending portion 134, together with the second plates 133a and 133b, can be made of metal. The bending portion 134 can transfer the heat generated by the first heating wire 115 to the outer wall of the refrigerator, which has a low temperature. This prevents condensation from forming on the surface.

[0191] A housing 140 may be attached to one side (e.g., the outer side) of the second plates 133a and 133b. The housing 140 can increase the strength of the second plates 133a and 133b. The housing 140 can protect the second plates 133a and 133b from external impacts. A bend 134 may be formed on one side of the housing 140 in a second direction. For convenience, the bend 134 of the second plates 133a and 133b may be designated as a first bend 134. The bend 1401 of the housing 140 may be designated as a second bend 134. The second bend 134 is formed to cover the first bend 134.

[0192] The first heating wire 115 can be connected to either the first bend 134 or the second bend 134. In this embodiment, the first heating wire 115 is shown connected to the housing 140 via the second bend 134.

[0193] The first heating wire 115 can be disposed on the inside or outside of the bend 134. In this embodiment, the first heating wire 115 is shown disposed on one side (e.g., the outside) of the bend 134.

[0194] A portion of the first hot wire 115 may be configured on one side (e.g., the outside) of the gasket 112.

[0195] The first hot line 115 can be configured at the corner where the second plates 133a, 133b of the first panels 101a, 101b intersect with the first surface of the door. Here, the second plates 133a, 133b of the first panels 101a, 101b can form one side of the refrigerator (e.g., the left side). The first surface of the door can form the left side of the door.

[0196] The first panels 101a and 101b include support members 136a and 136b disposed between the first plates 132a and 132b and the second plates 133a and 133b. The support members 136a and 136b include first support plates 1361a and 1361b, a plurality of rods 1363a and 1363b, and second support plates 1362a and 1362b. The first support plates 1361a and 1361b extend along the first plates 132a and 132b and form a surface supporting the first plates 132a and 132b. The second support plates 1362a and 1362b extend along the second plates 133a and 133b and form a surface supporting the second plates 133a and 133b.

[0197] A plurality of rods 1363a and 1363b are arranged spaced apart along the length of the first support plate and the second support plate 1362a and 1362b. One side of each rod 1363a and 1363b is connected to the first support plate 1361a and 1361b, and the other side is connected to the second support plate 1362a and 1362b. Thus, the first plate 132a and 132b and the second plate 133a and 133b are arranged spaced apart in one direction by a predetermined interval.

[0198] One part of the door may be made of vacuum insulation. The other part of the door may be made of insulation block 141, which is a non-vacuum insulation. The non-vacuum insulation may be made of polyurethane (PU) foam. The part of the door made of vacuum insulation is positioned towards one side (e.g., the outside) of the body 100. The other part of the door made of non-vacuum insulation is positioned towards the inside of the body 100.

[0199] A portion of the insulation block 141 may be formed protruding from one side of the door toward a first space formed on one side (e.g., the inside) of the body 100.

[0200] Figure 16 This is a conceptual diagram showing the state in which the hot wire 114 according to the invention is combined with the cover member 142 and connected to one side (e.g., the outer side) of the bend 134 of the second plates 133a, 133b.

[0201] The first heating wire 115 is combined with the cover member 142. The cover member 142 is formed to cover the first heating wire 115. Thus, the first heating wire 115 is shielded by the cover member 142 and is not exposed to the outside. The cover member 142 can shield the first heating wire 115 and make the appearance aesthetically pleasing. Therefore, since the cover member 142 makes the appearance aesthetically pleasing and is arranged on the front of the body 100, it can be named a front decorative element according to the prefix of decoration.

[0202] A portion of the insulation element that is coupled to one side (e.g., the inner side) of the first panels 101a, 101b may be formed at an angle to avoid interference with the insulation block 141 of the door.

[0203] The cover member 142 includes a heat wire receiving portion 146. The heat wire receiving portion 146 is formed to receive a first heat wire 115. The heat wire receiving portion 146 is configured to surround the first heat wire 115. The heat wire receiving portion 146 may be integrally formed with the cover member 142, or it may be manufactured separately and combined with the cover member 142. In this embodiment, the state in which the heat wire receiving portion 146 is integrally formed with the cover member 142 is shown.

[0204] One side of the cover member 142 is formed to surround the first panels 101a and 101b. The other side of the cover member 142 is formed to surround a portion of the drawer guide 137. In the absence of the drawer guide 137, the other side of the cover member 142 is formed to surround a portion of the first plates 132a and 132b of the heat insulation or a portion of the first heat insulation member 138a.

[0205] The cover member 142 may be composed of a first cover member 142a and a second cover member 142b. The first cover member 142a extends parallel to the first plates 132a and 132b in one direction to surround a portion of the first plates 132a and 132b. The second cover member 142b extends from the first cover member 142a in the other direction. The second cover member 142b is formed to surround the side plates 135a and 135b and the bend 134.

[0206] The cover member 142 is made of a material different from the metal material of the second plates 133a and 133b. The cover member 142 may be formed of a polymer-based resin with a lower thermal conductivity than the second plates 133a and 133b.

[0207] A first engaging portion 143 is provided on one side of the first cover member 142a. The first engaging portion 143 can be in the form of a hook or a protrusion. The first engaging portion 143 can engage with the drawer guide 137. A engaging portion 144 can be formed on one side of the drawer guide 137. The engaging portion 144 can be formed in the form of a groove. The hook or protrusion of the first engaging portion 143 can be inserted into the engaging portion 144 engaged with the first cover member 142a. However, the form of the first engaging portion 143 is not limited to this; on the contrary, an engaging groove can be formed in the first engaging portion 143, and a hook or protrusion can be formed protrudingly on the drawer guide 137.

[0208] A heat wire receiving portion 146 may be provided on one side of the second cover member 142b. The heat wire receiving portion 146 includes a first wall 1461 and a second wall 1463 protruding from the second cover member 142b toward the bend 134. The first wall 1461 is disposed on the side (e.g., the outer side) facing the second plates 133a and 133b. The first wall 1461 may form the same plane as the second plates 133a and 133b.

[0209] A bend 1462 may be formed at the end of the first wall 1461. The bend 1462 can improve the strength of the heat wire receiving portion 146. The bend 1462 bends from the first wall 1461 in the same direction as the bending direction of the bend 134, thereby allowing it to connect with the first heat wire 115. The bend 1462 is formed to be shorter than the bend 134. Thus, the bend 1462 can restrict the movement of the first heat wire 115.

[0210] The second wall 1463 is disposed inside the second plates 133a and 133b. The protruding length of the second wall 1463 can be longer than the protruding length of the first wall 1461. A second connecting portion 1464 is provided at the end of the second wall 1463. The second connecting portion 1464 can be formed in the form of a connecting groove, a hook, or a protrusion. In this embodiment, a state in which the second connecting portion 1464 is formed in the form of a hook is shown.

[0211] A receiving hole may be formed through in one direction between the first wall 1461 and the second wall 1463 to accommodate the heat wire 114. The receiving hole faces the bend 134. When the cover member 142 is attached to one side of the body 100, the receiving hole may be covered by the bend 134.

[0212] An inclined portion 1466 may be formed at the corner where the first cover member 142a and the second cover member 142b meet. The inclined portion 1466 can prevent the door from interfering with the heat insulation block 141 provided on one side (e.g., the inside) of the door when it is opened or closed.

[0213] The cover member 142 may be fitted with a magnet 147 to ensure a tight fit between the body 100 and the door when the door is closed. The magnet 147 may be disposed on one side (e.g., the inner side) of the second cover member 142b. The magnet 147 may be coupled to one side (e.g., the inner side) of the cover member 142 using various coupling means such as adhesive, hook coupling, coupling groove, or coupling protrusion. Thus, the magnet 147 pulls the door by magnetic interaction (i.e., attraction) with the magnet 113 built into the gasket 112 of the door, which is the opposite side, thereby providing a tight fit between the door and the body 100 when the door is closed.

[0214] In the following description, hot wire 114 refers to the first hot wire 115 disposed on one side of the main body 100.

[0215] Figure 17 This is a conceptual diagram showing the state in which the hot wire 114 is combined with the cover member 200 according to another embodiment of the present invention and the hot wire 114 is disposed on one side (e.g., the inner side) of the bend 134 of the second plates 133a, 133b.

[0216] This embodiment is similar to the one described above. Figure 16 The difference in the embodiment is that the hot wire receiving portion 205 is manufactured separately from the cover member 200 and is combined with the cover member 200, and the hot wire 114 is disposed on one side (e.g., the inside) of the bend 134.

[0217] The hot wire 114 is configured to connect to one side (e.g., the inner side) of the bend 134. Thus, the hot wire 114 can transfer heat to the second plates 133a and 133b through the bend 134, thereby preventing condensation on the surface of the refrigerator.

[0218] A housing 140 may be disposed on one side (e.g., the outer side) of the second plates 133a and 133b. The housing 140 extends from the first panels 101a and 101b to the second panel 102. Thus, the housing 140 can improve the strength of the second plates 133a and 133b, thereby preventing deformation (also known as unevenness) of the second plates 133a and 133b during the exhaust of the vacuum space.

[0219] An inner housing 139 may be disposed on the inner or outer side of the first plates 132a and 132b. Here, the outer side is the surface facing the first space formed on one side (e.g., the inner side) of the body 100. The inner housing 139 can extend from the first panels 101a and 101b to the second panel 102. Thus, the inner housing 139 can improve the strength of the first plates 132a and 132b, thereby preventing deformation of the first plates 132a and 132b when the vacuum space is vented. When a heat insulation member is filled into one side (e.g., the outer side) of the first plates 132a and 132b, the heat insulation member can be easily filled into the inner housing 139 even without the drawer guide 137.

[0220] A heat wire receiving portion 205 is received on one side (e.g., the inner side) of the cover member 200. The heat wire receiving portion 205 can be coupled to one side (e.g., the inner side) of the cover member 200. One side of the heat wire receiving portion 205 can be coupled to one side (e.g., the inner side) of the first cover member 142a. The other side of the heat wire receiving portion 205 can be coupled to one side (e.g., the inner side) of the second plates 133a, 133b.

[0221] The other side of the hot wire receiving portion 205 includes a first support portion 206. The first support portion 206 protrudes from the other side of the hot wire receiving portion 205 toward the side plates 135a and 135b in a first direction. Here, the first direction, as an example, could refer to the X-axis direction. Thus, the first support portion 206 can be closely attached to one side of the hot wire 114, thereby restricting the hot wire 114 from moving in a second direction different from the first direction. Here, the second direction, as an example, could refer to the Y-axis direction.

[0222] The other side of the hot wire receiving portion 205 includes a second support portion 207. The second support portion 207 is formed protruding from the first support portion 206 toward the second plates 133a, 133b in a second direction different from the first direction. Thus, the second support portion 207 can be closely attached to the side of the hot wire 114 that is different from the first side, thereby restricting the movement of the hot wire 114 in the first direction.

[0223] The other side of the heat wire receiving portion 205 includes a third support portion 209. The third support portion 209 protrudes from the second support portion 207 toward the side plates 135a and 135b in the first direction. The protruding length of the third support portion 209 is configured to connect the third support portion 209 to a portion of the side plates 135a and 135b. The third support portion 209 can be abutted against one side (e.g., the inner side) and one side (e.g., the outer side) of the second plates 133a and 133b, respectively. Thus, a portion of the heat wire receiving portion 205 can be abutted against the corner where the side plates 135a and 135b and the second plates 133a and 133b intersect, thereby strengthening the mutual support between the vacuum insulation body and the heat wire receiving portion 205.

[0224] A connecting hole 208 may be formed through one direction on one side of the hot wire receiving portion 205. Here, one direction may be the X-axis direction. The connecting hole 208 may be formed as a circle. The shape of the connecting hole 208 is not limited to this, and may be formed as a quadrilateral or other shapes.

[0225] A connecting protrusion 203 may be provided on one side (e.g., the inner side) of the cover member 200. The connecting protrusion 203 is formed protruding from one side (e.g., the inner side) of the second cover member 142b toward the connecting hole 208 of the hot wire receiving portion 205. The connecting protrusion 203 can be engaged by passing through the connecting hole 208. The connecting protrusion 203 and the connecting hole 208 can be engaged by an interference fit.

[0226] The protruding length of the protrusion 203 is designed to connect to the side corner of the drawer guide 137, which intersects with the first plates 132a and 132b. One side of the longitudinal end of the protrusion 203 can be configured to connect to the corner of the drawer guide 137, the first plates 132a and 132b, and the side plates 135a and 135b. This strengthens the support between the cover member 200 and the vacuum insulation.

[0227] A portion of the hot wire receiving portion 205 may be configured to overlap with the bend 134 on one side (e.g., the inside). Another portion of the hot wire receiving portion 205 may be configured not to overlap with the bend 134.

[0228] One side of the first cover member 142a can be bonded or joined to the drawer guide 137. In this embodiment, a state is shown in which one side of the first cover member 142a and the side corner of the drawer guide 137 are tightly attached to each other.

[0229] A plurality of protrusions 204 may be formed on one side (e.g., the inner side) of the second cover member 142b. At least two of the plurality of protrusions 204 are first protrusions 204 that support another portion of the hot wire receiving portion 205. Here, the other portion of the hot wire receiving portion 205 extends projectingly from one side (e.g., the inner side) of the bend 134 toward the first cover member 142a. Thus, it has the advantage of not only ensuring support for the other portion of the hot wire receiving portion 205 that does not overlap with the bend 134, but also facilitating the connection between the hot wire receiving portion 205 and the cover member 200.

[0230] At least two additional second protrusions 204 of the plurality of protrusions 204 are formed protruding from the second cover member 142b toward the curved portion 1401 of the outer casing 140. The plurality of second protrusions 204 are configured in connection with the curved portion 1401 of the outer casing 140. A magnet 147 may be attached between the first protrusion 204 and the second protrusions 204.

[0231] Other components are the same as those described above. Figures 1 to 16 The embodiments are the same or similar, so repeated descriptions will be omitted.

[0232] Figure 18 This illustrates the state in which the hot wire receiving portion 303 and the bending portion 301 are joined together according to another embodiment of the present invention.

[0233] This embodiment and Figure 17 The difference in the embodiment is the combination structure of the cover member 300 and the curved portion 301.

[0234] A hot wire receiving portion 303 is disposed on one side (e.g., the inner side) of the curved portion 301. A first support portion 304 and a second support portion 305 of the hot wire receiving portion 303 are configured to receive the hot wire 114. The first support portion 304 of the hot wire receiving portion 303 extends along a first direction. Here, the first direction, as an example, may refer to the X-axis direction. The first support portion 304 faces the second plates 133a and 133b across the hot wire 114. The first support portion 304 and the second plates 133a and 133b are disposed overlapping in the Y-axis direction, as described later. The first support portion 304 and the second plates 133a and 133b can restrict the movement of the hot wire 114 in the Y-axis direction.

[0235] The second support portion 305 of the hot wire receiving portion 303 extends from the first support portion 304 in a second direction different from the first direction. Here, the second direction may be the Y-axis direction. The second support portion 305 faces the bend portion 301 across the hot wire 114. The second support portion 305 and the bend portion 301 are arranged overlapping in the X-axis direction. The second support portion 305 and the bend portion 301 can restrict the movement of the hot wire 114 in the X-axis direction.

[0236] A connecting hole is formed through the bend 301. Connecting components such as screws can pass through the connecting hole and be connected to the hot wire receiving portion 303, which will be described later.

[0237] A boss 306 may be provided on the other side of the hot wire receiving portion 303. The boss 306 is formed protruding from the other side of the hot wire receiving portion 303 toward the side plates 135a and 135b in a first direction. Here, the first direction may refer to the X-axis direction.

[0238] An internal thread may be formed on one side (e.g., the inner side) of the boss portion 306. The internal thread engages with a screw. Thus, a connecting member such as a screw engages with the boss portion 306, thereby allowing the bent portion 301 and the hot wire receiving portion 303 to engage with each other. The cover member 300 can be engaged with the bent portion 301 via the hot wire receiving portion 303.

[0239] Other components are the same as those described above. Figure 17 The embodiments are the same or similar, so repeated descriptions will be omitted.

[0240] Figure 19 This is a conceptual diagram showing the state in which the hot wire receiving portion 403 and the bending portion 401 are joined together according to another embodiment of the present invention.

[0241] This embodiment is similar to the one described above. Figure 16 The difference is that the hot wire receiving part 403 and the cover member 412 are manufactured separately from each other, while the hot wire receiving part 403 is combined with the curved part 401.

[0242] This embodiment is similar to the one described above. Figures 16 to 18 The difference in this embodiment is that the hot wire 114 is not connected to the bend 401.

[0243] A portion of the bend 401 extends further in a second direction, not overlapping with the bend 411 of the housing 410, but overlapping with a portion of the hot wire receiving portion 403. Here, the second direction, as an example, can refer to the Y-axis direction. The extension length of the bend 401 can be formed such that its ratio to the side length of the vacuum space portion is greater than 1 / 2 and less than 1. A connecting hole 402 can be formed through the bend 401 in a first direction different from the first direction. A connecting protrusion 405 is formed protruding from the hot wire receiving portion 403 toward the connecting hole 402. The connecting protrusion 405 can penetrate the connecting hole 402 and engage with the bend 401. The connecting protrusion 405 and the bend 401 can be engaged via the connecting hole 402 in an interference fit manner.

[0244] The hot wire receiving portion 403 is disposed on one side (e.g., the outer side) of the curved portion 401.

[0245] One side of the first cover member 413 can engage with the drawer guide 416. A connecting protrusion 414 is formed protrudingly on one side of the first cover member 413. A protruding receiving groove 417 for receiving the connecting protrusion 414 is formed recessedly on one side of the drawer guide 416. The shapes of the connecting protrusion 414 and the protruding receiving groove 417 can be formed correspondingly to each other and fit together. The connecting protrusion 414 and the protruding receiving groove 417 can be engaged by an interference fit.

[0246] A heat wire 114 can be attached to one side of the heat wire receiving portion 403. A magnet 408 can be attached to the other side of the heat wire receiving portion 403. One side of the heat wire receiving portion 403 is configured to connect with the bent portion 401 of the second plates 133a and 133b. The other side of the heat wire receiving portion 403 is configured to connect with the bent portion 411 of the outer casing 410.

[0247] At least three receiving walls are formed protruding from the side of the hot wire receiving portion 403 opposite to the direction of the connecting protrusion 405 toward one side (e.g., the outer side) of the curved portion 401. A first receiving wall 406 of the plurality of receiving walls faces the first cover member 413. A second receiving wall 407 of the plurality of receiving walls faces one side (e.g., the outer side) of the second plates 133a, 133b. A third receiving wall 408 may be formed protruding between the first receiving wall 406 and the second receiving wall 407.

[0248] A space is formed between the second receiving wall 407 and the third receiving wall 408 to accommodate the heat wire 114. A space is formed between the third receiving wall 408 and the first receiving wall 406 to accommodate the magnet 408. The first receiving wall 406 can be connected to one side of the second cover member 415.

[0249] A first receiving hole is formed between the second receiving wall 407 and the third receiving wall 408 on the side facing the bend 401 (e.g., the outer side). The hot wire 114 can be received and connected through the first receiving hole.

[0250] A second receiving hole is formed between the third receiving wall 408 and the first receiving wall 406 on the side facing the bend 401 (e.g., the outer side). The magnet 408 can be received and engaged through the second receiving hole.

[0251] The second cover member 415 may extend from one side of the first cover member 413 to cover the first receiving hole and the second receiving hole. One side of the second cover member 415 may be provided with a curved portion 411 surrounding the second receiving wall 407. The curved portion 411 may be configured to overlap with the second receiving wall 407 in one direction. Here, as an example of one direction, it may refer to the Y-axis direction.

[0252] One side of the bend 411 (e.g., the inner side) may be connected to one side of the second receiving wall 407. The other side of the bend 411 (e.g., the outer side) may be coplanar with the second plates 133a, 133b or the outer casing 410.

[0253] One side of the hot wire receiving part 403 can be connected to the housing 410 and the bending part 401.

[0254] One side of the hot wire receiving portion 403 can be disposed between the second cover member 415 and the outer casing 410. Another side of the hot wire receiving portion 403 can be disposed between the second cover member 415 and the bend 401. Thus, the hot wire 114 is not connected to the outer casing 410 or the bend 401 due to one side of the hot wire receiving portion 403. If the hot wire 114 is connected to either the outer casing 410 or the bend 401, the anti-condensation effect can be improved. Conversely, heat supplied from the condenser 119 can be transferred to the outer casing 410 or the bend 401 through the hot wire 114, thereby increasing heat loss.

[0255] If the hot wire 114 is not connected to the housing 410 or the bend 401, the anti-condensation effect may be reduced. Conversely, the heat loss from the condenser 119 can be reduced.

[0256] Thus, the hot wire receiving portion 403 and the cover member 412 surround the hot wire 114 and the magnet 408, thereby optimizing the thickness of the hot wire receiving portion 403 and the cover member 412.

[0257] Other components and Figures 1 to 18 The embodiments are the same or similar, so repeated descriptions will be omitted.

[0258] Figure 20 This is a conceptual diagram showing the combined structure of the curved portion 401 and the cover member 500 according to another embodiment of the present invention.

[0259] A plurality of protruding walls are provided on one side (e.g., the inner side) of the second cover member 503. A first protruding wall 504 of the plurality of protruding walls is formed protruding in one direction toward the side plates 135a, 135b. A second protruding wall 506 of the plurality of protruding walls faces one side (e.g., the outer side) of the outer casing 410. The length of the first protruding wall 504 protruding from one side (e.g., the inner side) of the second cover member 503 is longer than the length of the second protruding wall 506 protruding from one side (e.g., the inner side) of the second cover member 503. A mating groove 505 is formed on one side (e.g., the inner side) of the first protruding wall 504.

[0260] The engaging groove 505 is formed to accommodate one side of the bent portion 401. One side of the bent portion 401 can engage with the engaging groove 505. The engaging portion 502 is formed protruding from one side of the first cover member 413 toward the drawer guide 508. The engaging groove 509 is formed recessed on one side of the drawer guide 508 in the protruding direction of the engaging portion 502.

[0261] A heat wire connection portion 511 and a magnet connection portion 511 may be provided between a plurality of protruding walls. A connecting protrusion 507 may be formed between the heat wire connection portion 511 and the magnet connection portion 511. The connecting protrusion 507 can be tightly connected to one side of the heat wire 114.

[0262] Other components are the same as those described above. Figures 1 to 19 The embodiments are the same or similar, so repeated descriptions will be omitted.

[0263] Figure 21 This is a conceptual diagram illustrating the state of a vacuum insulation body combined with a cover member 600 and an insulation element, according to another embodiment of the present invention.

[0264] This embodiment is similar to the one described above. Figures 1 to 20 The difference in this embodiment is that the hot wire 114 is not attached to the cover member 600.

[0265] The temperature difference between the inside and outside of the first storage chamber 106 is relatively smaller than that between the inside and outside of the second storage chamber 107.

[0266] Therefore, the hot wire 114 is primarily used in the second storage compartment 107 and may not be integrated with the first storage compartment 106. The hot wire 114 may be configured on one side of the body 100 to surround the outer periphery of the second storage compartment 107. In the case of the first storage compartment 106, the drawer guide 508 is not integrated on one side (e.g., the inner side) of the first panels 101a, 101b.

[0267] The inner housing 139 may not extend from the first plates 132a, 132b of the first panels 101a, 101b to the second panel 102. The first thermal insulation member 603 may extend to only surround a portion of the first plates 132a, 132b to which the inner housing 139 does not extend. A joint 602 may be provided on one side of the first cover member 413. Due to the components of the drawer guide 508 (not joined), the joint 602 may be directly joined to the first plates 132a, 132b of the vacuum insulation body by means of welding or the like.

[0268] Other components are the same as those described above. Figures 1 to 16 The embodiments are the same or similar, so repeated descriptions will be omitted.
