[0024] According to an embodiment of the present invention, the following effects can be achieved.

[0025] First, the hotline is connected to the condenser and the expander. The hotline can be divided into a first hotline section, a second hotline section, and a third hotline section based on the direction of refrigerant flow.

The hotline can prevent condensation on the surface forming the exterior of the refrigerator.

[0026] Second, the bend formed on one side of the main body can secure the strength of the insulation by bending one edge of the second plate of the insulation. This can prevent distortion of the panel shape due to vacuum and high-temperature exhaust during the production of the vacuum insulation panel.

[0027] Third, the hotline can be connected to a folded portion formed on one side of the main body, thereby transferring heat to the outer casing or second plate of the vacuum insulator that forms the exterior of the refrigerator. Furthermore, the cover member can be joined to one side of the main body using the folded portion.

[0028] Fourth, a portion of the hotline can be housed in the machine room, preventing damage from exposure. A portion of the hotline can be connected to a portion of the machine room's metal exterior wall for additional heat dissipation.

[0029] Fifth, multiple support frames are arranged on one side of the main body. The multiple support frames are attached to and supported by the outer wall of the machine room. This allows the multiple support frames to support the main body.

[0030] Sixth, the hot line accommodated in the machine room is extended to bypass the cycle components accommodated in the machine room, such as the condenser, compressor, printed circuit board, and support frame, thereby avoiding interference with the cycle components.

[0102] A refrigerator according to the present invention includes a main body (100) and a door (not shown).

[0103] At least two panels of the main body (100) form the exterior of the refrigerator. The main body (100) may be composed of a plurality of panels.

[0104] For example, the panels constituting the main body (100) include one (101a) of the first panels (101a, 101b), another (101b) of the first panels (101a, 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. An example of the side may be a back side of the refrigerator. The third panel (103) forms another side of the refrigerator. An example of the other side may be a top side of the refrigerator. Each of the one (101a) of the first panels (101a, 101b) and / or the other (101b) of the first panels (101a, 101b) forms another side of the refrigerator. As another example of the above another side, the left side and the right side of the refrigerator can be formed respectively. One (101a) of the first panels (101a, 101b) and / or the other (101b) of the first panels (101a, 101b) can be composed of one (101a) of the first panels (101a, 101b) and the other (101b) of the first panels (101a, 101b) which are arranged to face each other in the Y-axis direction. The fourth panel (104) can form another side of the refrigerator. As an example of the above another side, the fourth panel (104) can form the bottom side or one side.

[0105] A machine room (117), which will be described later, can be installed on the fourth panel (104). In this embodiment, the machine room (117) is shown installed on one side of the fourth panel (104).

[0106] 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), one (101a) of the first panel (101a, 101b) and / or the other (101b) of the first panel (101a, 101b) and the fourth panel (104).

[0107] In this embodiment, one (101a) of the second panel (102), the third panel (103), the first panel (101a, 101b) and / or the other (101b) of the first panel (101a, 101b) is configured as a vacuum insulator. However, the fourth panel (104), which will be described later, is configured as a non-vacuum insulator.

[0108] A storage room is formed inside the main body (100). The storage room includes a first storage room (106) and / or a second storage room (107). The first storage room (106) and the second storage room (107) may be arranged to be spaced apart from each other in the Z-axis direction or the Y-axis direction of the main body (100).

[0109] The door includes a first storage compartment door (109) and / or a second storage compartment door (110).

[0110] The first storage room (106) and the second storage room (107) can be partitioned by a partition wall (108). The partition wall (108) can extend in one direction (e.g., horizontally) in the X-axis direction and the Y-axis direction from one side (101a) of one of the first panels (101a, 101b) to one side (101b) of the other of the first panels (101a, 101b).

[0111] The partition wall (108) may be positioned between 1 / 3 and 2 / 3 of the height (vertical distance) between the third panel (103) and the fourth panel (104) when the height is divided into three equal parts. In this embodiment, the partition wall (108) is positioned at approximately 1 / 3 of the height from the fourth panel (104).

[0112] 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 compared to the thickness.

[0113] An opening is formed on one side of the main body (100). Through this opening, items to be stored in the storage room, such as food, can be brought in and out of the storage room. One side of the door is arranged to be connected to one side of the main body (100), and the storage room can be sealed using a gasket (112) described below.

[0114] A gasket (112) is placed between one side of the door and one side of the body (100). In this embodiment, the gasket (112) is shown as being coupled to one side of the door. A gasket joint portion (1121) is formed on one side (e.g., an inner side) of the gasket (112) so as to protrude toward one side of the door. The gasket joint portion is formed on one side of the door so as to be recessed in the protruding direction of the gasket joint portion (1121). The gasket joint portion (1121) is coupled to the gasket joint portion. Through this, the gasket (112) can be coupled to one side of the door.

[0115] The gasket (112) may be made of an elastic material such as rubber. The gasket (112) can maintain an airtight seal 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., the inner side) of the gasket (112). Through this, the magnetism of the magnet (113) embedded in the gasket (112) can be utilized to secure close contact between the door and the main body (100).

[0116] The refrigerator is configured to prevent surface dew formation caused by temperature differences between the inside and outside of the refrigerator by using a hot line (114).

[0117] The hot line (114) is a component that dissipates heat. For example, the hot line (114) may be formed in the shape of a circular tube that extends so that refrigerant flows inside. The hot line (114) is connected to the condenser (119), and can receive heat generated from the condenser (119) and dissipate heat. The hot line (114) transfers heat to the connecting surface of the first storage compartment door (109) and / or the second storage compartment door (110), thereby preventing condensation from occurring due to a temperature difference between the outside and inside of the refrigerator.

[0118] The second storage room (107) may have a greater temperature difference between the inside and outside of the first storage room (106). Therefore, the hot line (114) may be applied to the second storage room (107) rather than the first storage room (106). In this embodiment, the hot line (114) is shown applied to the second storage room (107).

[0119] The first storage room (106) may be formed on a portion of a plurality of first panels (101a, 101b), a portion of a second panel (102), an inner side of each of the third panels (103), and one side of the partition wall (108). The second storage room (107) may be formed on another portion of a plurality of first panels (101a, 101b), an inner side of each of the other portions of the second panels (102), the other side of the partition wall (108), and one side (e.g., the inner side) of the fourth panel (104).

[0120] A part of the hot line (114) is arranged on one side of the main body (100). A part of the hot line (114) may be named a first hot line (115) for convenience of explanation. The first hot line (115) may be arranged on another part of the plurality of first panels (101a, 101b) forming the second storage chamber (107), one side of the partition wall (108) and / or one side of the fourth panel (104). One side of each of the other parts of the plurality of first panels (101a, 101b), the partition wall (108) and the fourth panel (104) faces one side of the door. The first hot line (115) may be formed by bending a single circular pipe into a closed loop shape.

[0121] The first hot line (115) may be formed in an approximately rectangular shape. According to the present embodiment, the first side (1151) (upstream side) of the first hot line (115) may extend in one direction, for example, in the +Y-axis direction (right direction), from the center of one side of the fourth panel (104) along one side of the fourth panel (104) based on the flow direction of the refrigerant (counterclockwise when viewed from the front).

[0122] The second side (1152) of the first hot line (115) may be extended by bending along one side of one (101a) of the plurality of first panels (101a, 101b) from the first side (1151) of the first hot line (115) in the direction of the flow of the refrigerant in another direction, for example, in the +Z-axis direction (upward).

[0123] The third side (1153) of the first hot line (115) may be extended by bending along one side of the partition wall (108) from the second side (1152) of the first hot line (115) in another direction, for example, in the -Y-axis direction (left direction), based on the flow direction of the refrigerant.

[0124] The fourth side (1154) of the first hot line (115) may be extended by bending in another direction, for example, in the -Z-axis direction (downward), along one side of another one (101b) of the plurality of first panels (101a, 101b) from the third side (1153) of the first hot line (115) based on the flow direction of the refrigerant.

[0125] The fifth side (1155) (downstream side) of the first hot line (115) may extend in one direction, for example, in the +Y-axis direction (right direction), along one side of the fourth panel (104) from one edge of the fourth panel (104) to the center of one side of the fourth panel (104) based on the flow direction of the refrigerant.

[0126] The first side (1151) of the first hotline (115) and the fifth side (1155) of the first hotline (115) can be joined to each other so as to meet and be connected. For example, the first side (1151) of the first hotline (115) and the fifth side (1155) of the first hotline (115) can be joined by welding or the like.

[0127] However, the first side (1151) of the first hot line (115) and the fifth side (1155) of the first hot line (115) are 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 a closed loop shape. The refrigerant flowing along the first hot line (115) can move counterclockwise from the first side (1151) of the first hot line (115) to the fifth side (1155) of the first hot line (115).

[0128] The first hotline (115) can be connected to one side (e.g., the inside) of the cover member (142) (also called front decoration) to be covered by the cover member (142) described later.

[0129] Another part of the hotline (114) is placed inside the machine room (117). Another part of the hotline (114) may be named a second hotline (116) for convenience of explanation.

[0130] The first part (1161) of the second hot line (116) may extend from the outlet of the condenser (119) to be described later toward one side of the machine room (117) to be described later. Here, the one side of the machine room (117) may mean the front of the machine room (117) as an example of the one side. The first part (1161) of the second hot line (116) is connected to the outlet of the condenser (119) and the first side (1151) of the first hot line (115).

[0131] The second part (1162) of the second hot line (116) can extend from one side of the machine room (117) toward the expander (120) to be described later. The second part (1162) of the second hot line (116) is connected to the fifth side (1155) of the first hot line (115) and the expander (120).

[0132] The first part (1161) and the second part (1162) of the second hotline (116) may be arranged to be spaced apart from each other. However, a part of the first part (1161) of the second hotline (116) connected to the first side (1151) of the first hotline (115) and a part of the second part (1162) of the second hotline (116) connected to the fifth side (1155) of the first hotline (115) may be arranged adjacent to each other and combined.

[0133] The covers constituting the machine room (117) include one (1171a) of the first covers (1171a, 1171b), another (1171b) of the first covers (1171a, 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 the one side, it may form the rear side of the machine room (117). The third cover (1173) forms another side of the machine room (117). As an example of the other side, it may form the front side of the machine room (117). One (1171a) of the first covers (1171a, 1171b) and the other (1171b) of the first covers (1171a, 1171b) each form another side of the machine room (117). As an example of the other side, the left side and the right side of the machine room (117) may be formed, respectively. One (1171a) of the first covers (1171a, 1171b) and the other (1171b) of the first covers (1171a, 1171b) may be arranged to face each other in the Y-axis direction. In the present embodiment, one (1171a) of the first covers (1171a, 1171b) forms the left side of the machine room (117), and the other (1171b) of the first covers (1171a, 1171b) forms the right side of the machine room (117). The fourth cover (1174) forms another side of the machine room (117). As an example of the another side, the fourth cover (1174) may form a bottom side or one side. The other side of the machine room (117) may be formed to be open. Here, the other side may be an upper side of the machine room (117). The other side of the machine room (117) may be configured to be covered by the fourth panel (104). The fourth panel (104) is configured to partition the storage room and the machine room (117) of the main body (100). The fourth panel (104) can partition the second storage room (107) and the machine room (117).

[0134] The fourth panel (104) may be supported by a plurality of support frames (148a, 148b) in the machine room (117). The support frames (148a, 148b) may extend in one direction. Here, an example of the one direction may refer to the Y-axis direction. One side of the support frame (148a, 148b) may be coupled to one (1171a) of the plurality of first covers (1171a, 1171b), and the other side of the support frame (148a, 148b) may be coupled to another one (1171b) of the plurality of first covers (1171a, 1171b).

[0135] One side of the fourth panel (104) may be coupled to one side of a plurality of first covers (1171a, 1171b). Here, one side of the fourth panel (104) may mean, for example, the lower surface of the fourth panel (104). One side of the first cover (1171a, 1171b) may mean, for example, the upper surface of the first cover (1171a, 1171b).

[0136] The plurality of support frames (148a, 148b) may be composed of a first support frame (148a) and a second support frame (148b). The first support frame (148a) is arranged to be spaced apart from the third cover (1173). The second support frame (148b) is arranged to be spaced apart from the first support frame (148a) in the X-axis direction. The second support frame (148b) is arranged to be spaced apart from the second cover (1172).

[0137] The machine room (117) is configured to accommodate a part of the refrigeration cycle device, such as a compressor (118), a condenser (119), an expander (120), etc.

[0138] A condenser (119) is arranged on one side of the machine room (117). A compressor (118) is arranged on the other side of the machine room (117). The condenser (119) and the compressor (118) are arranged to be spaced apart from each other in one direction. A cooling fan (123) is arranged between the condenser (119) and the compressor (118). The cooling fan (123) is configured to cool the condenser (119) by using air flow. The cooling fan (123) is configured to cause air to flow in one direction within the machine room (117). The air flow of the cooling fan (123) can correspond to the arrangement direction of the condenser (119) and the compressor (118).

[0139] The condenser (119) may be arranged adjacent to one (1171a) of the plurality of first covers (1171a, 1171b) within the machine room (117). The compressor (118) may be arranged adjacent to another (1171b) of the plurality of first covers (1171a, 1171b) within the machine room (117).

A plurality of exhaust ports may be formed to penetrate in one direction through another (1171b) of the plurality of first covers (1171a, 1171b).

[0141] The cooling fan (123) has a plurality of blades (1232) rotatably installed inside the fan casing (1231) to induce the air flow direction in one direction. The cooling fan (123) can inhale external air through the intake port (126). The cooling fan (123) can induce the air flow direction to the condenser (119). The cooling fan (123) can induce the air flow direction to the compressor (118). The cooling fan (123) can exhaust the air that has passed through the condenser (119) and the compressor (118) to the outside through the exhaust port.

[0142] A plurality of ducts are installed inside the machine room (117). The ducts are effective in directing the air flow direction in one direction. This allows the air circulating inside and outside the machine room (117) to be efficiently cooled, such as the condenser (119), without being dispersed. The plurality of ducts include a first duct (124) and a second duct (125).

[0143] The first duct (124) extends in one direction. The first duct (124) is configured to isolate the interior space of the machine room (117) and the condenser (119). The first duct (124) accommodates the condenser (119). Air flow can be formed inside the first duct (124). One side of the first duct (124) is connected to the intake port (126) so as to surround the intake port (126). The other side of the first duct (124) surrounds a portion of the cooling fan (123).

[0144] The second duct (125) extends in one direction. The second duct (125) is configured to isolate the internal space of the machine room (117) and the compressor (118). The second duct (125) accommodates the compressor (118). Air flow can be formed inside the second duct (125). One side of the second duct (125) surrounds a portion of the cooling fan (123). The other side of the second duct (125) surrounds the exhaust port and is formed to be in communication with the exhaust port.

[0145] The intake port (126) may be formed in the central portion of one (1171a) of the plurality of first covers (1171a, 1171b). The exhaust port may be formed in the central portion of another (1171b) of the plurality of first covers (1171a, 1171b).

[0146] The condenser (119) and the compressor (118) are coupled to the fourth cover (1174). The fourth cover (1174) may be referred to as a base cover in that it is coupled to a refrigeration cycle device housed inside the machine room (117).

[0147] The condenser (119) and the first duct (124) may be located in the central portion between the second cover (1172) and the third cover (1173). The compressor (118) and the second duct (125) may be located in the central portion between the second cover (1172) and the third cover (1173). The distance between the condenser (119) and the first duct (124) and the second cover (1172) may be the same as the distance between the condenser (119) and the first duct (124) and the third cover (1173). The distance between the compressor (118) and the second duct (125) and the second cover (1172) may be the same as the distance between the compressor (118) and the second duct (125) and the third cover (1173).

[0148] The condenser (119) may be placed close to the first cover (1171a, 1171b). The compressor (118) may be placed close to the second cover (1172).

[0149] A dryer (121) may be placed between the second cover (1172) and the first duct (124). The dryer (121) is configured to dry the refrigerant. The dryer (121) is formed in a cylindrical shape. The dryer (121) may extend in one direction.

[0150] One side of the dryer (121) is positioned apart from the second cover (1172). The other side of the dryer (121) is positioned apart from the first duct (124). The gap between one side of the dryer (121) and the second cover (1172) may be smaller than the gap between the other side of the dryer (121) and the first duct (124).

[0151] A drain (128) may be placed 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 placed on one side of the evaporator. As an example, the drain may extend downward on the one side. The evaporator and the drain (128) may be placed to overlap in the Z-axis direction.

[0152] One side of the drain (128) is connected to the drain pipe of the evaporator. The other side of the drain (128) is connected to the outside. The other side of the drain (128) may be formed to penetrate the fourth cover (1174). Through this, the defrost water and the like generated in the evaporator can be discharged to the outside through the drain (128).

[0153] A three-way valve (122) may be placed 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 the overall operation of the refrigeration cycle device. 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.

[0154] One side of the three-way valve (122) is positioned adjacent to the second cover (1172). The other side of the three-way valve (122) is positioned apart from the second duct (125).

[0155] An expander (120) may be positioned between the second cover (1172) and the second duct (125). The expander (120) may be formed as a capillary tube. The capillary tube is formed in the shape of a circular tube with a thin diameter. For example, the diameter of the capillary tube is formed smaller than the diameter of a cycle pipe, for example, a refrigerant pipe connecting a dryer (121) and a three-way valve (122). Through this, the capillary tube can expand the refrigerant. The capillary tube may be composed of at least two. Through this, the capillary tube can increase heat exchange efficiency.

[0156] One side of the capillary is positioned adjacent to the second cover (1172). The other side of the capillary is positioned apart from the second duct (125).

[0157] A printed circuit board (130) may be placed 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 combined with the printed circuit board (130).

[0158] The printed circuit board (130) is formed in a rectangular plate shape. The printed circuit board (130) is arranged in one direction (e.g., horizontally) on the fourth cover (1174). One side of the printed circuit board (130) is arranged adjacent to the third cover (1173). The other side of the printed circuit board (130) may be arranged to be spaced apart from the second duct (125).

[0159] The third cover (1173) is placed on one side (e.g., the outer side) of the main body (100). When the third cover (1173) forms one side (e.g., the front side) of the machine room (117), it can be detachably coupled to the machine room (117). As a result, since the third cover (1173) is placed on the front side of the machine room (117), there is an advantage in that it is easy for a worker to perform maintenance, such as repairing a malfunction of the printed circuit board (130).

[0160] A harness (131) may be placed between another one (1171b) of the plurality of first covers (1171a, 1171b) and the compressor (118). The harness (131) refers to a bundle of electric wires for supplying power, etc. to the electric components of the refrigerator, and signal wires for transmitting and receiving signals.

[0161] One end of the harness (131) is electrically connected to a printed circuit board (130). The other end of the harness (131) may be electrically connected to an electrical component such as a motor. The harness (131) may extend along one side of the other (1171b) of the first covers (1171a, 1171b). The harness (131) is extended to bypass the compressor (118).

[0162] The second hotline (116) is configured to bypass cycle components housed inside the machine room (117), such as a condenser (119), a compressor (118), a printed circuit board (130), etc.

[0163] As described above, the first part (1161) of the second hotline (116) and the second part (1162) of the second hotline (116) are connected to the first hotline (115), but are positioned spaced apart from each other. This provides the advantage of making it easy to avoid interference between the hotline (114) and cycle components. In addition, there is the advantage of making it easy to couple the hotline (114) with the cover member (142), which will be described later.

[0164] A portion of the first part (1161) of the second hotline (116) extends from the outlet of the condenser (119) to penetrate a portion of the first duct (124).

[0165] A part of the first part (1161) of the second hot line (116) may be spaced apart from one (1171a) of the plurality of first covers (1171a, 1171b) in one direction by a preset distance and may extend in parallel. A part of the first part (1161) of the second hot line (116) may be spaced apart from the cooling fan (123) in one direction by a preset distance. The distance between a part of the first part (1161) of the second hot line (116) and one (1171a) of the first covers (1171a, 1171b) is smaller than the distance between a part of the first part (1161) of the second hot line (116) and the cooling fan (123). Through this, it is easy for the first part (1161) of the second hotline (116) to avoid interference with components such as the condenser (119) and cooling fan (123).

[0166] A portion of the first part (1161) of the second hotline (116) may be positioned adjacent to the fourth cover (1174). This makes it easy to avoid interference with components such as the condenser (119) and cooling fan (123).

[0167] A portion of the first part (1161) of the second hotline (116) may be positioned adjacent to the third cover (1173). This facilitates connection between a portion of the first part (1161) of the second hotline (116) and the first side (1151) of the first hotline (115). This facilitates connection between the hotline (114) and the cover member (142).

[0168] A part 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 part of the first part (1161) of the second hot line (116) may extend in a first direction along the fourth cover (1174), and another part of the first part (1161) of the second hot line (116) may extend in a bending manner in a second direction different from the first direction along the third cover (1173). At this time, the inclined part of the first part (1161) of the second hot line (116) can easily avoid interference with other cycle components, such as a printed circuit board (130).

[0169] A portion of the second portion (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 portion (1162) of the second hot line (116) may extend so as to penetrate a portion of the first duct (124).

[0170] A part of the second part (1162) of the second hotline (116) may extend in parallel with one (1171a) of the plurality of first covers (1171a, 1171b) and spaced apart in one direction by a preset distance. A part of the second part (1162) of the second hotline (116) may be arranged to be spaced apart in one direction by a preset distance. The distance between a part of the second part (1162) of the second hotline (116) and one (1171a) of the first covers (1171a, 1171b) is greater than the distance between a part of the second part (1162) of the second hotline (116) and a part of the first part (1161) of the second hotline (116). Through this, it is easy for the second part (1162) of the second hot line (116) to avoid interference with components such as the condenser (119) and the cooling fan (123). The second part (1162) of the second hot line (116) is arranged to be spaced apart from the first covers (1171a, 1171b), so that leakage of heat generated from the second hot line (116) can be minimized. On the other hand, a part of the first part (1161) of the second hot line (116) can be arranged to be connected to a part of the outer wall of the machine room (117) for heat dissipation. As an example of the outer wall, it can be connected to the third cover (1173).

[0171] A portion of the second part (1162) of the second hotline (116) may be positioned adjacent to the fourth cover (1174). This makes it easy to avoid interference with components such as the condenser (119) and cooling fan (123).

[0172] A portion of the second part (1162) of the second hotline (116) may be positioned adjacent to the third cover (1173). This facilitates connection between a portion of the second part (1162) of the second hotline (116) and the fifth side (1155) of the first hotline (115). This facilitates connection between the hotline (114) and the cover member (142).

[0173] A part of the first part (1161) of the second hot line (116) is drawn out from the machine room (117). A part of the first part (1161) of the second hot line (116) can be drawn out through the drawing portion (1451) of the cover member (142). The drawing portion (1451) may be provided on one side of the cover member (142) that covers one side of the fourth panel (104). Here, as an example of one side of the fourth panel (104), the front of the fourth panel (104) may be meant. As an example of one side of the cover member (142), the central part of the cover member (142) may be meant. The drawing portion (1451) may be formed to penetrate one side of the cover member (142). The withdrawal section (1451) can be connected to the machine room (117).

[0174] 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) can be drawn out from the machine room (117) through the withdrawal part (1451) and connected to the upstream side of the first side (1151) of the first hot line (115).

[0175] The downstream side of the first part (1161) of the second hot line (116) extends in the first direction and extends in a bending manner in a second direction different from the first direction, so as to pass through the withdrawal part (1451) and be connected to the upstream side of the first side (1151) of the first hot line (115).

[0176] Based on the flow direction of the refrigerant flowing along the hot line (114), the downstream side of the fifth side (1155) of the first hot line (115) can be introduced into the machine room (117) through the outlet (1451) and connected to the upstream side of the second part (1162) of the second hot line (116).

[0177] The downstream side of the fifth side (1155) of the first hot line (115) extends in the second direction and extends in a bending manner in the first direction different from the second direction, passes through the withdrawal portion (1451), and can be connected to the upstream side of the second part (1162) of the second hot line (116).

[0178] The upstream side of the first side (1151) of the first hot line (115) and the downstream side of the fifth side (1155) of the first hot line (115) are arranged adjacent to each other at the withdrawal portion (1451), which is one side of the cover member (142) extended to cover one surface of the fourth panel (104).

[0179] The downstream side of the first part (1161) of the second hotline (116) and the upstream side of the second part (1162) of the second hotline (116) are arranged adjacent to each other at the withdrawal part (1451), which is one side of the cover member (142) extended to cover one side of the fourth panel (104).

[0180] Through this, a part of the hot line (114) that is drawn out from the machine room (117) to one side of the main body (100) can be easily connected through the drawing portion (1451) of the cover member (142).

[0181] A part of the second part (1162) of the second hot line (116) is formed to be inclined with respect to the third cover (1173). For example, a part of the second part (1162) of the second hot line (116) may extend in a first direction along the fourth cover (1174), and another part of the second part (1162) of the second hot line (116) may extend in a bending manner in a second direction different from the first direction along the third cover (1173). At this time, the inclined part of the first part (1161) of the second hot line (116) can easily avoid interference with other cycle components, such as a printed circuit board (130).

[0182] A part of the first part (1161) of the second hotline (116) and a part of the second part (1162) of the second hotline (116) may be placed at the corner where one of the first covers (1171a, 1171b) (1171a) and the third cover (1173) meet.

[0183] A part of the second part (1162) of the second hotline (116) may extend in one direction along the second cover (1172) at a preset interval from the second cover (1172) and be connected to one side of the dryer (121).

[0184] A part of the second part (1162) of the second hotline (116) may extend in one direction along the second cover (1172) at a preset interval from the second cover (1172), thereby connecting 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.

[0185] The first panel (101a, 101b) is composed of a vacuum insulator. The second plate (133a, 133b) constituting the vacuum insulator may extend in a first direction. Here, the first direction may be the X-axis direction. A bending portion (134) may be provided on one side of the second plate (133a, 133b). Here, the one side may be a part (e.g., a front end) of the second plate (133a, 133b) facing an opening formed on one surface of the main body (100). The bending portion (134) is formed to be bent in a second direction different from the first direction on one side of the second plate (133a, 133b). Here, the second direction may be the Y-axis direction.

[0186] According to this configuration, the bending portion (134) can improve the strength of the vacuum insulation panel, thereby preventing distortion of the panel's shape due to vacuum and high-temperature exhaust during the production of the vacuum insulation panel.

[0187] The bending portion (134) can be used to connect the conduction of the hot line (114) and the cover member (142) described later.

[0188] The bending portion (134) is positioned on one side (e.g., the outer side) of the sealing portion where the second plate (133a, 133b) and the side plate (135a, 135b) are sealed. The bending portion (134) can be formed by bending the end of the second plate (133a, 133b) in two layers.

[0189] The length of the bending portion (134) extending in the second direction may be formed to be smaller than the side length of the vacuum space portion. The length of the bending portion (134) extending in the second direction may be formed to be smaller than the gap between the second plates (133a, 133b) and the first plates (132a, 132b). It is preferable that the length of the bending portion (134) be approximately half the side length of the vacuum space portion.

[0190] The bending portion (134) is arranged to be spaced apart from the side plates (135a, 135b). The bending portion (134) may be arranged to overlap a portion of the side plates (135a, 135b) in the X-axis direction.

[0191] The drawer guide (137) may be positioned apart from the first plate (132a, 132b). Optionally, the drawer guide (137) may not be provided in the first storage chamber (106) but may be provided in the second storage chamber (107). The drawer guide (137) may guide the drawer to be inserted into or withdrawn from the main body (100).

[0192] The drawer guide (137) can be formed of a plastic material that can be injection molded using a polymer resin with low thermal conductivity.

[0193] Optionally, a first insulation material (138a) may be provided between the drawer guide (137) and the first plate (132a, 132b). The first insulation material (138a) may be composed of polyurethane foam. Through this, the first insulation material (138a) can reinforce the insulation performance of the vacuum insulation body that insulates heat leakage between the outside and inside of the furnace. Optionally, even when the first insulation material (138a) is not provided between the drawer guide (137) and the first plate (132a, 132b), the empty space between the drawer guide (137) and the first plate (132a, 132b) can have the effect of insulating heat leakage between the outside and inside of the furnace.

[0194] The first insulation material (138a) can extend along the first plate (132a, 132b) based on the edge of the first plate (132a, 132b) that meets the side plate (135a, 135b).

[0195] An inner casing (139) may be provided between the first plate (132a, 132b) and the first insulation material (138a). The inner casing (139) may be made of a metal material. The inner casing (139) reinforces the strength of the thin first plate (132a, 132b) and can prevent a portion of the first plate (132a, 132b) from being warped.

[0196] A portion of the first plate (132a, 132b) may not have the inner casing (139) applied. The first insulation material (138a) may extend to a portion of the first plate (132a, 132b) to which the inner casing (139) is not applied.

[0197] Optionally, a second insulation material (138b) may be provided between the bending portion (134) and the side plates (135a, 135b). The second insulation material (138b) may be composed of polyurethane foam. In this way, the second insulation material (138b) may reinforce the insulation performance of the vacuum insulation body that insulates heat leakage between the outer and inner parts. Optionally, the second insulation material (138b) may not be provided between the bending portion (134) and the side plates (135a, 135b).

[0198] The first hot line (115) may be arranged to be connected to a bending portion (134). The bending portion (134) may be formed of a metal material together with the second plates (133a, 133b). The bending portion (134) may transfer heat generated from the first hot line (115) to the outer wall of the refrigerator, which has a low temperature. This may have the effect of preventing surface condensation.

[0199] An outer casing (140) may be coupled to one side (e.g., the outer side) of the second plate (133a, 133b). The outer casing (140) may enhance the strength of the second plate (133a, 133b). The outer casing (140) may protect the second plate (133a, 133b) from external impact. A bending portion (134) may be formed in the second direction on one side of the outer casing (140). The bending portion (134) of the second plate (133a, 133b) may be conveniently referred to as a first bending portion (134). The bending portion (1401) of the outer casing (140) may be referred to as a second bending portion (134). The second bend (134) is formed to cover the first bend (134).

[0200] The first hot line (115) can be connected to the first bend (134) or the second bend (134). In this embodiment, the first hot line (115) is shown connected to the outer casing (140) through the second bend (134).

[0201] The first hot line (115) can be placed on the inside or outside of the bend (134). In this embodiment, the first hot line (115) is shown placed on one side (e.g., the outside) of the bend (134).

[0202] A part of the first hot line (115) may be placed on one side (e.g., the outer side) of the gasket (112).

[0203] The first hotline (115) may be positioned at the corner where the second plate (133a, 133b) of the first panel (101a, 101b) meets the first side of the door. Here, the second plate (133a, 133b) of the first panel (101a, 101b) may form one side (e.g., the left side) of the refrigerator. The first side of the door may form the left side of the door.

[0204] The first panel (101a, 101b) includes a support (136a, 136b) arranged between the first plate (132a, 132b) and the second plate (133a, 133b). The support (136a, 136b) includes a first support plate (1361a, 1361b), a plurality of bars (1363a, 1363b), and a second support plate (1362a, 1362b). The first support plate (1361a, 1361b) extends along the first plate (132a, 132b) to support one surface of the first plate (132a, 132b). The second support plate (1362a, 1362b) extends along the second plate (133a, 133b) to support one surface of the second plate (133a, 133b).

[0205] A plurality of bars (1363a, 1363b) are spaced apart from each other along the length direction of the first and second support plates (1362a, 1362b). One side of the bars (1363a, 1363b) is connected to the first support plate (1361a, 1361b), and the other side of the bars (1363a, 1363b) is connected to the second support plate (1362a, 1362b). As a result, the first plates (132a, 132b) and the second plates (133a, 133b) are spaced apart from each other in one direction at a constant interval.

[0206] A portion of the door may be made of vacuum insulation. Another portion of the door may be made of an insulating block (141) that is a non-vacuum insulation. The non-vacuum insulation may be made of PU foam. A portion of the door made of vacuum insulation is positioned toward one side (e.g., the outer side) of the main body (100). Another portion of the door made of non-vacuum insulation is positioned toward the inner side of the main body (100).

[0207] A part of the insulation block (141) may be formed to protrude toward a first space formed on one side (e.g., on the inside) of the main body (100) on one side of the door.

[0208] Figure 16 is a conceptual diagram showing a hot line (114) according to the present invention being coupled to a cover member (142) and connected to one side (e.g., the outer side) of a bent portion (134) of a second plate (133a, 133b).

[0209] The first hot line (115) is connected to the cover member (142). The cover member (142) is configured to cover the first hot line (115). As a result, the first hot line (115) is covered by the cover member (142) and is not exposed to the outside. The cover member (142) can cover the first hot line (115) to provide an attractive appearance. Accordingly, the cover member (142) can be named a front decoration following the decoration in that it provides an attractive appearance and is arranged on the front of the main body (100).

[0210] The insulation material attached to one side (e.g., the inner side) of the first panel (101a, 101b) may be formed so that a portion of the insulation material is inclined to avoid interference with the insulation block (141) of the door.

[0211] The cover member (142) includes a hotline receiving portion (146). The hotline receiving portion (146) is configured to receive the first hotline (115). The hotline receiving portion (146) is configured to surround the first hotline (115). The hotline receiving portion (146) may be formed integrally with the cover member (142) or may be manufactured separately and then coupled to the cover member (142). In the present embodiment, the hotline receiving portion (146) is shown to be formed integrally with the cover member (142).

[0212] One side of the cover member (142) is configured to wrap around one side of the first panel (101a, 101b). The other side of the cover member (142) is configured to wrap around a portion of the drawer guide (137). In the absence of the drawer guide (137), the other side of the cover member (142) is configured to cover a portion of the first plate (132a, 132b) of the insulation or a portion of the first insulation material (138a).

[0213] 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 in one direction parallel to the first plates (132a, 132b) so as to surround a portion of the first plates (132a, 132b). The second cover member (142b) extends in the other direction from the first cover member (142a). The second cover member (142b) is formed so as to surround the side plates (135a, 135b) and the folded portion (134).

[0214] The cover member (142) is composed of a metal material and a different material from the second plate (133a, 133b). The cover member (142) may be formed of a polymer-based resin having a lower thermal conductivity than the second plate (133a, 133b).

[0215] A first coupling portion (143) is provided on one side of the first cover member (142a). The first coupling portion (143) may be implemented in the form of a hook or a protrusion. The first coupling portion (143) may be coupled with a drawer guide (137). A coupling portion (144) may be formed on one side of the drawer guide (137). The coupling portion (144) may be formed in the form of a groove. The hook or protrusion of the first coupling portion (143) may be inserted and coupled into the coupling portion (144) of the first cover member (142a). However, the shape of the first coupling portion (143) is not limited thereto. Conversely, a coupling groove may be formed on the first coupling portion (143), and a hook or a protrusion may be formed to protrude from the drawer guide (137).

[0216] A hotline receiving portion (146) may be provided on one side of the second cover member (142b). The hotline receiving portion (146) includes a first wall (1461) and a second wall (1463) that protrude from the second cover member (142b) toward the bending portion (134). The first wall (1461) is arranged toward one side (e.g., the outer side) of the second plate (133a, 133b). The first wall (1461) may be flush with the second plate (133a, 133b).

[0217] A bend (1462) may be formed at an end of the first wall (1461). The bend (1462) may enhance the strength of the hot line receiving portion (146). The bend (1462) may be connected to the first hot line (115) by bending in the same direction as the bending direction of the bend (134) in the first wall (1461). The bend (1462) is formed to be shorter than the bend (134). Through this, the bend (1462) may restrict the movement of the first hot line (115).

[0218] The second wall (1463) is positioned toward the inside of the second plate (133a, 133b). The second wall (1463) may be formed to have a longer protrusion length than the protrusion length of the first wall (1461). A second connecting portion (1464) is provided at an end of the second wall (1463). The second connecting portion (1464) may be formed to protrude in the form of a connecting groove, a hook, or a protrusion. In the present embodiment, the second connecting portion (1464) is shown as being formed in a hook shape.

[0219] A receiving hole may be formed to penetrate in one direction between the first wall (1461) and the second wall (1463) so that a hot line (114) can be received. The receiving hole faces the folded portion (134). When the cover member (142) is attached to one surface of the main body (100), the receiving hole may be covered by the folded portion (134).

[0220] 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) may prevent interference with an insulating block (141) provided on one side (e.g., the inside) of the door when the door is opened or closed.

[0221] The cover member (142) can be coupled with a magnet (147) to secure a close contact between the main body (100) and the door when the door is closed. The magnet (147) can be placed on one side (e.g., the inner side) of the second cover member (142b). The magnet (147) can be coupled to one side (e.g., the inner side) of the cover member (142) by various coupling means such as adhesion, hook coupling, coupling groove, or coupling protrusion. Through this, the magnet (147) can magnetically interact with the magnet (113) embedded in the gasket (112) of the door as a counterpart, i.e., pull the door with gravity, thereby providing a close contact between the door and the main body (100) when the door is closed.

[0222] In the following description, hotline (114) refers to the first hotline (115) arranged on one side of the main body (100).

[0223] FIG. 17 is a conceptual diagram showing a hot line (114) coupled to a cover member (200) according to another embodiment of the present invention, and the hot line (114) arranged on one side (e.g., on the inside) of a bent portion (134) of a second plate (133a, 133b).

[0224] This embodiment differs from the embodiment of FIG. 16 described above in that the hotline receiving portion (205) is manufactured separately from the cover member (200) and is joined to the cover member (200) and the hotline (114) is arranged on one side (e.g., on the inside) of the bending portion (134).

[0225] The hot line (114) is arranged to be connected to one side (e.g., the inner side) of the bending portion (134). Through this, the hot line (114) can transfer heat to the second plates (133a, 133b) through the bending portion (134), thereby preventing the formation of condensation on the surface of the refrigerator.

[0226] An outer casing (140) may be placed on one side (e.g., the outer side) of the second plate (133a, 133b). The outer casing (140) may extend from the first panel (101a, 101b) to the second panel (102). In this way, the outer casing (140) increases the strength of the second plate (133a, 133b), thereby preventing the second plate (133a, 133b) from being distorted (so-called, creaking) when air is exhausted from the vacuum space.

[0227] An inner casing (139) may be arranged on the inner or outer surface of the first plate (132a, 132b). Here, the outer surface is a surface facing the first space formed on one side (e.g., the inner side) of the main body (100). The inner casing (139) may extend from the first panel (101a, 101b) to the second panel (102). Through this, the inner casing (139) can increase the strength of the first plate (132a, 132b), thereby preventing the first plate (132a, 132b) from being distorted when air is exhausted from the vacuum space. In the case where the inner casing (139) is filled with insulation material on one side (e.g., the outer side) of the first plate (132a, 132b), the insulation material can be easily filled even without the drawer guide (137).

[0228] The hotline receiving portion (205) is received on one side (e.g., on the inner side) of the cover member (200). The hotline receiving portion (205) can be coupled to one side (e.g., on the inner side) of the cover member (200). One side of the hotline receiving portion (205) can be coupled to one surface (e.g., on the inner side) of the first cover member (142a). The other side of the hotline receiving portion (205) can be coupled to one surface (e.g., on the inner side) of the second plate (133a, 133b).

[0229] The other side of the hotline receiving portion (205) includes a first support portion (206). The first support portion (206) is formed to protrude in a first direction toward the side plates (135a, 135b) from the other side of the hotline receiving portion (205). Here, an example of the first direction may refer to the X-axis direction. Through this, the first support portion (206) can be brought into close contact with one side of the hotline (114) to restrict the hotline (114) from moving in a second direction different from the first direction. Here, an example of the second direction may refer to the Y-axis direction.

[0230] The other side of the hotline receiving portion (205) includes a second support portion (207). The second support portion (207) is formed to protrude in a second direction different from the first direction from the first support portion (206) toward the second plate (133a, 133b). Through this, the second support portion (207) can be brought into close contact with one side and the other side of the hotline (114), thereby restricting the hotline (114) from moving in the first direction.

[0231] The other side of the hotline receiving portion (205) includes a third support portion (209). The third support portion (209) is formed to protrude in the first direction from the second support portion (207) toward the side plates (135a, 135b). The protruding length of the third support portion (209) is formed so that the third support portion (209) is connected to a part of the side plates (135a, 135b). The third support portion (209) can be in close contact with one surface (e.g., inner surface) of the second plate (133a, 133b) and one surface (e.g., outer surface) of the side plates (135a, 135b), respectively. Through this, a part of the hotline receiving portion (205) is pressed against the corner where the side plates (135a, 135b) and the second plate (133a, 133b) meet, so that the vacuum insulator and the hotline receiving portion (205) can reinforce each other's supporting force.

[0232] A coupling hole (208) may be formed to penetrate in one direction on one side of the hotline receiving portion (205). Here, the one direction may be the 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 square shape.

[0233] A coupling protrusion (203) may be provided on one side (e.g., the inner side) of the cover member (200). The coupling protrusion (203) is formed to protrude from one side (e.g., the inner side) of the second cover member (142b) toward the coupling hole (208) of the hot line receiving portion (205). The coupling protrusion (203) may be coupled by penetrating the coupling hole (208). The coupling protrusion (203) and the coupling hole (208) may be coupled by a force fit.

[0234] The protruding length of the coupling protrusion (203) is formed so as to be connectable to the side edge of the drawer guide (137) that meets the first plate (132a, 132b). One side of the longitudinal end of the coupling protrusion (203) can be formed so as to be connected to a part of the side of the drawer guide (137) and the edge where the first plate (132a, 132b) and the side plate (135a, 135b) are connected. Through this, the supporting force between the cover member (200) and the vacuum insulation body can be strengthened.

[0235] A portion of the hotline receiving portion (205) may be arranged to overlap with the bend portion (134) on one side (e.g., on the inner side) of the bend portion (134). Another portion of the hotline receiving portion (205) may be arranged to not overlap with the bend portion (134).

[0236] One side of the first cover member (142a) can be bonded or joined to the drawer guide (137). In this embodiment, one side of the first cover member (142a) and the side edge of the drawer guide (137) are shown in close contact with each other and bonded.

[0237] A plurality of protrusions (204) may be formed on one surface (e.g., inner surface) of the second cover member (142b). At least two first protrusions (204) among the plurality of protrusions (204) are configured to support another portion of the hotline receiving portion (205). Here, the other portion of the hotline receiving portion (205) protrudes and extends from one surface (e.g., inner surface) of the bent portion (134) toward the first cover member (142a). This not only ensures support for another portion of the hotline receiving portion (205) that is not overlapped with the bent portion (134), but also provides the advantage of easy coupling of the hotline receiving portion (205) and the cover member (200).

[0238] Among the plurality of protrusions (204), at least two second protrusions (204) are formed to protrude from the second cover member (142b) toward the bending portion (1401) of the outer casing (140). The plurality of second protrusions (204) are arranged to be connected to the bending portion (1401) of the outer casing (140). A magnet (147) can be coupled between the first protrusion (204) and the second protrusion (204).

[0239] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 16 described above, duplicate descriptions will be omitted.

[0240] Fig. 18 shows a hotline receiving portion (303) and a bending portion (301) coupled to each other according to another embodiment of the present invention.

[0241] The present embodiment differs from the embodiment of Fig. 17 described above in the joint structure of the cover member (300) and the bending portion (301).

[0242] The hotline receiving portion (303) is arranged on one side (e.g., on the inner side) of the bending portion (301). The first support portion (304) and the second support portion (305) of the hotline receiving portion (303) are configured to receive the hotline (114). The first support portion (304) of the hotline receiving portion (303) extends in a first direction. Here, the first direction may mean, for example, the X-axis direction. The first support portion (304) faces the second plates (133a, 133b) with the hotline (114) therebetween. The first support portion (304) and the second plates (133a, 133b) are arranged to overlap in the Y-axis direction, which will be described later. The first support portion (304) and the second plates (133a, 133b) can restrict the hotline (114) from moving in the Y-axis direction.

[0243] The second support portion (305) of the hotline receiving portion (303) extends from the first support portion (304) in a second direction different from the first direction. Here, the second direction may refer to the Y-axis direction as an example. The second support portion (305) faces the bend portion (301) with the hotline (114) therebetween. The second support portion (305) and the bend portion (301) are arranged to overlap in the X-axis direction. The second support portion (305) and the bend portion (301) can restrict the hotline (114) from moving in the X-axis direction.

[0244] A connecting hole is formed through the bending portion (301). A connecting member such as a screw can pass through the connecting hole and be connected to the hot line receiving portion (303) described later.

[0245] A boss portion (306) may be provided on the other side of the hotline receiving portion (303). The boss portion (306) is formed to protrude in a first direction toward the side plates (135a, 135b) from the other side of the hotline receiving portion (303). Here, the first direction may mean the X-axis direction as an example.

[0246] A female screw portion may be formed on one side (e.g., on the inside) of the boss portion (306). The female screw portion is coupled with a screw. Through this, a coupling member such as a screw is coupled to the boss portion (306), thereby allowing the bending portion (301) and the hot line receiving portion (303) to be coupled to each other. The cover member (300) may be coupled to the bending portion (301) via the hot line receiving portion (303).

[0247] Since other configurations are the same or similar to the embodiment of Fig. 17 described above, duplicate descriptions will be omitted.

[0248] Fig. 19 is a conceptual diagram showing a hotline receiving portion (403) and a bending portion (401) coupled to each other according to another embodiment of the present invention.

[0249] This embodiment is different from the embodiment of FIG. 16 described above in that the hotline receiving portion (403) and the cover member (412) are manufactured separately from each other, and the hotline receiving portion (403) is coupled to the bending portion (401).

[0250] This embodiment differs from the embodiments of FIGS. 16 to 18 described above in that the hot line (114) is not connected to the bending portion (401).

[0251] A part of the bending portion (401) does not overlap with the bending portion (411) of the outer casing (410) and is further extended to protrude in a second direction so as to overlap with a part of the hot line receiving portion (403). Here, the second direction may refer to the Y-axis direction as an example. The extension length of the bending portion (401) may be formed at a ratio greater than 1 / 2 and less than 1 compared to the side length of the vacuum space portion. A coupling hole (402) may be formed to penetrate through the bending portion (401) in a first direction different from the first direction. A coupling protrusion (405) is formed to protrude toward the coupling hole (402) in the hot line receiving portion (403). The coupling protrusion (405) may penetrate through the coupling hole (402) and be coupled to the bending portion (401). The joining projection (405) and the bending portion (401) can be joined by force fitting through the joining hole (402).

[0252] The hotline receiving section (403) is placed on one side (ex. outer side) of the bending section (401).

[0253] One side of the first cover member (413) can be coupled with the drawer guide (416). A coupling protrusion (414) is formed to protrude on one side of the first cover member (413). A projection receiving groove (417) can be formed to be recessed on one side of the drawer guide (416) to receive the coupling protrusion (414). The coupling protrusion (414) and the projection receiving groove (417) can be formed to have corresponding shapes and be combined. The coupling protrusion (414) and the projection receiving groove (417) can be coupled by a force fit.

[0254] A hotline (114) may be coupled to one side of the hotline receiving portion (403). A magnet (408) may be coupled to the other side of the hotline receiving portion (403). One side of the hotline receiving portion (403) is arranged to be connected to the bending portion (401) of the second plate (133a, 133b). The other side of the hotline receiving portion (403) is arranged to be connected to the bending portion (411) of the outer casing (410).

[0255] On the other side of the hotline receiving portion (403) facing in the opposite direction from the coupling projection (405), at least three receiving walls are formed to protrude toward one side (e.g., the outer side) of the bending portion (401). Among the plurality of receiving walls, a first receiving wall (406) faces the first cover member (413). Among the plurality of receiving walls, a second receiving wall (407) faces one side (e.g., the outer side) of the second plate (133a, 133b). A third receiving wall (408) may be formed to protrude between the first receiving wall (406) and the second receiving wall (407).

[0256] A space is formed between the second receiving wall (407) and the third receiving wall (408) in which a hot line (114) can be accommodated. A space is formed between the third receiving wall (408) and the first receiving wall (406) in which a magnet (408) can be accommodated. The first receiving wall (406) can be connected to one surface of the second cover member (415).

[0257] A first receiving hole is formed between the second receiving wall (407) and the third receiving wall (408) toward one side (ex. outer side) of the bending portion (401). A hot line (114) can be received and connected through the first receiving hole.

[0258] A second receiving hole is formed between the third receiving wall (408) and the first receiving wall (406) toward one side (e.g., the outer side) of the bending portion (401). A magnet (408) can be received and coupled through the second receiving hole.

[0259] 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. A bending portion (411) may be provided on one side of the second cover member (415) to surround the second receiving wall (407). The bending portion (411) may be arranged to overlap the second receiving wall (407) in one direction. Here, an example of one direction may mean the Y-axis direction.

[0260] One side (e.g., inner side) of the bending portion (411) may be connected to one side of the second receiving wall (407). The other side (e.g., outer side) of the bending portion (411) may be flush with the second plate (133a, 133b) or the outer casing (410).

[0261] One side of the hotline receiving portion (403) can be connected to the outer casing (410) and the bending portion (401).

[0262] One side of the hot line receiving portion (403) may be arranged between the second cover member (415) and the outer casing (410). One side of the hot line receiving portion (403) may be arranged between the second cover member (415) and the bend portion (401). Through this, the hot line (114) is not connected to the outer casing (410) and the bend portion (401) by one side of the hot line receiving portion (403). When the hot line (114) is connected to the outer casing (410) or the bend portion (401), the dew formation prevention effect can be enhanced. On the other hand, heat provided from the condenser (119) may be transferred to the outer casing (410) or the bend portion (401) through the hot line (114), which may increase heat loss.

[0263] If the hot line (114) is not connected to the outer casing (410) or the bending portion (401), the dew formation prevention effect may be reduced. On the other hand, the heat loss provided from the condenser (119) may be reduced.

[0264] Through this, the hotline receiving portion (403) and the cover member (412) can wrap around the hotline (114) and the magnet (408), thereby optimizing the thickness of the hotline receiving portion (403) and the cover member (412).

[0265] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 18, duplicate descriptions will be omitted.

[0266] Fig. 20 is a conceptual diagram showing the joint structure of a bending portion (401) and a cover member (500) according to another embodiment of the present invention.

[0267] A plurality of protruding walls are provided on one side (e.g., inner side) of the second cover member (503). Among the plurality of protruding walls, a first protruding wall (504) is formed to protrude in one direction toward the side plates (135a, 135b). A second protruding wall (506) among the plurality of protruding walls faces one side (e.g., outer side) of the outer casing (410). The length of the first protruding wall (504) protruding from one side (e.g., inner side) of the second cover member (503) may be formed longer than the length of the second protruding wall (506) protruding from one side (e.g., inner side) of the second cover member (503). A joining groove (505) is formed on one side (e.g., inner side) of the first protruding wall (504).

[0268] The joining groove (505) is formed to accommodate one side of the bending portion (401). One side of the bending portion (401) can be joined to the joining groove (505). A joining portion (502) is formed on one side of the first cover member (413) to protrude toward the drawer guide (508). A joining groove (509) can be formed to be recessed in the protruding direction of the joining portion (502) on one side of the drawer guide (508).

[0269] A hotline coupling portion (511) and a magnetic coupling portion (511) may be provided between a plurality of protruding walls. A coupling protrusion (507) may be formed to protrude between the hotline coupling portion (511) and the magnetic coupling portion (511). The coupling protrusion (507) may be tightly coupled to one side of the hotline (114).

[0270] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 19 described above, duplicate descriptions will be omitted.

[0271] Fig. 21 is a conceptual diagram showing a cover member (600) and an insulating material combined in a vacuum insulator according to another embodiment of the present invention.

[0272] This embodiment differs from the embodiments of FIGS. 1 to 20 described above in that the hotline (114) is not coupled to the cover member (600).

[0273] The temperature difference between the inside and outside of the first storage room (106) is relatively smaller than the temperature difference between the inside and outside of the second storage room (107).

[0274] For this reason, the hot line (114) is mainly used in the second storage room (107) and may be uncoupled to the first storage room (106). The hot line (114) may be arranged on one side of the main body (100) so as to surround the outer perimeter of the second storage room (107). In the case of the first storage room (106), the drawer guide (508) may be uncoupled to one side (e.g., the inner side) of the first panel (101a, 101b).

[0275] The inner casing (139) may not extend from the first plate (132a, 132b) of the first panel (101a, 101b) to the second panel (102). The first insulation material (603) may extend to cover only a portion of the first plate (132a, 132b) to which the inner casing (139) does not extend. A joining portion (602) may be provided on one side of the first cover member (413). The joining portion (602) may be directly joined to the first plate (132a, 132b) of the vacuum insulation body by welding or the like due to the absence (non-joining) of the drawer guide (508).

[0276] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 16 described above, duplicate descriptions will be omitted.
