Description

Insulator

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

As a related prior art regarding a hotline and a covering member covering it, Patent Document 10-2021-0078845 A (June 29, 2021) discloses a vacuum insulator and a refrigerator. According to the disclosure of the patent document, a hotline is provided on the outer surface of a partition member that divides a freezer into upper and lower parts.

A separate foam member is provided as an insulating member inside the partition member. The internal insulating member is covered with a cover housing made of resin material, and a hot line is connected to the cover housing. The hot line is covered by a hot line cover. The hot line cover acts as a heat transfer agent to prevent dew formation on the outside.

However, the cover housing of the patent document has disadvantages in terms of assembly and strength because it has no bonding structure other than being bonded to the vacuum insulator.

Therefore, a combined structure of the cover housing and the vacuum insulator is required.

Additionally, the shape and arrangement of the cover housing, hot line, and hot line cover must be different depending on the shape of the vacuum insulator.

In addition, the cover housing of the patent document is structured to be in contact with the thin plate portion of the vacuum insulation, so there is a risk that a vacuum leak may occur due to damage to the vacuum insulation when an external impact is applied.

The purpose of the present invention is to provide a refrigerator having a structure capable of solving the above-described problems.

The first objective is to provide a refrigerator having a structure in which a cover member on which a hot line is installed and a vacuum insulation material can be joined by means other than adhesive.

The second purpose is to provide a refrigerator having a structure that can increase the degree of freedom in the shape and/or arrangement of peripheral components to which a hot line is coupled, depending on the shape of the vacuum insulation body.

The third purpose is to provide a refrigerator having a structure capable of minimizing damage to the vacuum insulation material due to external impact that may be applied to the cover member.

The insulator of the present invention may be provided as at least one insulator. For example, the insulator of the present invention may provide a first wall extending in one direction; and a second wall extending in a direction different from the one direction. As another example, the insulator of the present invention may include a first insulator and a second insulator. The second insulator may be provided as a separate component separated from the first insulator. The second insulator may be connected to the first insulator by a connecting member.

One side of the cover member may be coupled with the bending portion, and/or the other side of the cover member may be coupled with the drawer guide.

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

First, the cover member attached to one side of the main body can have a hot line attached to one side (e.g., the inner side). The hot line can prevent condensation on the surface forming the exterior of the refrigerator.

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. Through this, the shape distortion of the panel due to vacuum and high-temperature exhaust can be prevented when manufacturing the vacuum insulation panel.

Third, the hot line can be connected to a folded portion formed on one side of the main body to transfer heat to the second plate of the outer casing or vacuum insulation material forming the exterior of the refrigerator. In addition, the cover member can be connected to one side of the main body by utilizing the folded portion.

Fourth, the cover member can be respectively connected to the bending portion and the drawer guide arranged on one side (e.g., the inner side) of the main body.

Through this, the cover member can improve the convenience of manufacturing and/or assembling the insulator. In addition, the cover member can improve the insulation performance by wrapping at least one side of the insulator. In addition, the cover member is advantageous in securing the strength of the insulator.

Fifth, since the cover member is not directly bonded to the first plate, which is a thin plate portion of the insulation, but is bonded to the drawer guide, no direct external force is applied to the thin plate portion of the insulation, thereby ensuring the safety of the vacuum insulation panel.

Sixth, the cover member is filled with insulation on one side (e.g., the inner side). The insulation extends to the drawer guide, so that the effect of insulating the heat bridge, which is a vulnerable part of the vacuum insulation panel to heat loss, can be obtained.

A refrigerator according to the present invention includes a main body (100) and/or a door (not shown). 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.

For example, at least two panels constituting the main body (100) include one (101a) of the first panel (101a, 101b), the other (101b) of the first panel (101a, 101b), the second panel (102), the third panel (103) and/or the fourth panel (104). The second panel (102) forms one side of the refrigerator. As an example of the one side, it may form the back of the refrigerator. The third panel (103) forms another side of the refrigerator. As an example of the other side, it may form the top of the refrigerator. One (101a) of the first panel (101a, 101b) and/or the other (101b) of the first panel (101a, 101b) forms another side of the refrigerator. As another example of the above another side, the left side and/or the right side of the refrigerator may be formed. One (101a) of the first panels (101a, 101b) and the other (101b) of the first panels (101a, 101b) may be formed by one (101a) of the first panels (101a, 101b) and the other (101b) of the first panels (101a, 101b) being arranged to face each other in the Y-axis direction. The fourth panel (104) may form another side of the refrigerator. As an example of the above another side, the fourth panel (104) may form a bottom side or one side.

A machine room (117) to be described later can be installed in the fourth panel (104). In this embodiment, the machine room (117) is shown installed on one side of the fourth panel (104).

The vacuum insulation body can form at least one or a part of at least one of the second panel (102), the third panel (103), one (101a) of the first panel (101a, 101b), the other (101b) of the first panel (101a, 101b), and the fourth panel (104). In the present embodiment, 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) are configured as vacuum insulation bodies. However, the fourth panel (104) described below is shown as being configured as a non-vacuum insulation body.

A storage room is formed inside the main body (100). The storage room is formed to be open toward one side (e.g., the front) of the main body (100). The storage room includes a first storage room (106) and a second storage room (107). The second storage room (107) can be maintained at a preset first temperature, for example, -20?. However, it is not limited to the preset first temperature. The first storage room (106) can be maintained at a preset second temperature, for example, +5?. However, it is not limited to the preset second temperature.

The storage room is a space in which heat exchange with the outside of the main body (100) is blocked to maintain a temperature lower than room temperature.

The first storage room (106) and/or the second storage room (107) may be arranged spaced apart from each other in the Z-axis direction or the Y-axis direction of the main body (100).

The door includes a first storage door (109) and/or a second storage door (110). The first storage door (109) is provided on one side (e.g., front) of the main body (100) and is configured to open and close the first storage room (106). The second storage door (110) is provided on one side (e.g., front) of the main body (100) and is configured to open and close the second storage room (107).

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 the first panel (101a, 101b) to one side (101b) of the other first panel (101a, 101b).

The partition wall (108) can 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).

The partition wall (108) may be formed in a rectangular shape. The partition wall (108) may have a thickness in the Z-axis direction. The partition wall (108) may be extended longer in the X-axis direction and the Y-axis direction compared to the thickness.

An opening is formed on one side of the main body (100). Through the opening, items to be stored in the storage room, such as food, can be brought in and out of the storage room. One side (e.g., the inner 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 later.

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

The gasket (112) may be made of an elastic material such as rubber. The gasket (112) may maintain a 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) may be used to secure a close contact between the door and the main body (100).

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

The hot line (114) is a component that emits heat. For example, the hot line (114) may be formed in a circular tube shape 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 emit heat. The hot line (114) transmits heat to the connecting surface of the first storage compartment door (109) or/and the second storage compartment door (110), thereby preventing condensation from occurring due to a temperature difference between the outside and inside of the refrigerator.

The second storage room (107) may have a greater temperature difference between the inside and outside than 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).

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

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 room (107), one side of the partition wall (108) and/or one side of the fourth panel (104). Another part of the plurality of first panels (101a, 101b), one side of the partition wall (108) and/or one side of the fourth panel (104) faces one side (e.g., the inner side) of the door. The first hot line (115) may be formed by bending a single circular pipe into a closed loop shape.

The first hotline (115) may be formed as a polygon or an approximately rectangular shape. The first hotline may include at least one of the first, second, third, fourth, and fifth sides. According to the present embodiment, the first side (1151) (upstream side) of the first hotline (115) may extend from the center of one side of the fourth panel (104) along one side of the fourth panel (104) in one direction, for example, in the +Y-axis direction (right direction), based on the flow direction of the refrigerant (counterclockwise when viewed from the front).

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

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.

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 one panel (101b) or one side of another one (101b) of a 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.

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), from one edge of the fourth panel (104) toward the center of one side of the fourth panel (104) or along one side of the fourth panel (104) to the center of one side based on the flow direction of the refrigerant.

The first side (1151) of the first hotline (115) and the fifth side (1155) of the first hotline (115) can be connected to each other by meeting each other. For example, the first side (1151) of the first hotline (115) and the fifth side (1155) of the first hotline (115) can be sealed or connected by welding or the like.

However, the first side (1151) of the first hot line (115) and the fifth side (1155) of the first hot line (115) are combined in a separate state. 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 form. 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).

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

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.

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).

The second part (1162) of the second hot line (116) may 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/or the expander (120).

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.

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 the other 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/or 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).

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

One side of the fourth panel (104) may be joined to one side of the first cover (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).

The support frame (148a, 148b) may be composed of a first support frame (148a) and/or 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).

The other side of the second duct (125) surrounds the exhaust port and is formed to communicate with the exhaust port.

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).

The condenser (119) and/or 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 accommodated inside the machine room (117).

The condenser (119) and/or the first duct (124) may be located in a portion (e.g., a central portion) between the second cover (1172) and the third cover (1173). The compressor (118) and/or the second duct (125) may be located in a portion (e.g., a 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).

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).

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.

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).

A drain (128) may be arranged 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 arranged 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 arranged to overlap in the Z-axis direction.

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 water generated in the evaporator, etc. may be discharged to the outside through the drain (128).

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 switch the flow direction of the refrigerant according to the control signal.

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).

An expander (120) may be placed between the second cover (1172) and the second duct (125). The expander (120) may be provided as a capillary tube. The capillary tube is formed in a circular tube shape 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.

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).

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 on the printed circuit board (130).

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).

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 attached 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 fault in the printed circuit board (130).

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 electric components of the refrigerator, and signal wires for transmitting and receiving signals.

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

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.

As described above, the first part (1161) of the second hot line (116) and the second part (1162) of the second hot line (116) are connected to the first hot line (115), but are arranged to be spaced apart from each other. Through this, there is an advantage in that it is easy to avoid interference between the hot line (114) and the cycle parts. In addition, there is an advantage in that the coupling between the cover member (142) described below and the hot line (114) is easy.

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

Some of the first portion (1161) of the second hotline (116) may be spaced apart from the first cover (1171a) in one direction by a preset distance and/or may extend in parallel. Some of the first portion (1161) of the second hotline (116) may be spaced apart from one of the plurality of first covers (1171a, 1171b) in one direction by a preset distance and/or may extend in parallel. Some of the first portion (1161) of the second hotline (116) may be arranged spaced apart from the cooling fan (123) in one direction by a preset distance. The gap 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 gap 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 hot line (116) to avoid interference with components such as the condenser (119) and/or the cooling fan (123).

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

A part of the first part (1161) of the second hotline (116) may be placed adjacent to the third cover (1173). This facilitates connection between a part of the first part (1161) of the second hotline (116) and the first side (1151) of the first hotline (115). The hotline (114) and the cover member (142) are easily joined.

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/or another part of the first part (1161) of the second hot line (116) may extend in a second direction different from the first direction along the third cover (1173). In this case, it is easy for the inclined part of the first part (1161) of the second hot line (116) to avoid interference with other cycle components, such as a printed circuit board (130).

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 to penetrate a portion of the first duct (124).

Some of the second portions (1162) of the second hotline (116) may be spaced apart from the plurality of first covers (1171a) in one direction by a preset interval and/or may extend in parallel. Some of the second portions (1162) of the second hotline (116) may be spaced apart from the plurality of first covers (1171a, 1171b) in one direction by a preset interval and/or may extend in parallel. Some of the second portions (1162) of the second hotline (116) may be spaced apart from the plurality of first portions (1161) of the second hotline (116) in one direction by a preset interval. The gap between a part of the second part (1162) of the second hot line (116) and one (1171a) of the first covers (1171a, 1171b) is greater than the gap between a part of the second part (1162) of the second hot line (116) and a part of the first part (1161) of the second hot line (116). Through this, the second part (1162) of the second hot line (116) can easily avoid interference with components such as a condenser (119) and/or a 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 in the second hot line (116) can be minimized. On the other hand, a part of the first part (1161) of the second hotline (116) may 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 may be connected to the third cover (1173).

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

A part of the second part (1162) of the second hotline (116) may be placed adjacent to the third cover (1173). This facilitates connection between a part of the second part (1162) of the second hotline (116) and the fifth side (1155) of the first hotline (115). The hotline (114) and the cover member (142) are easily joined.

A part of the first part (1161) of the second hotline (116) is drawn out from the machine room (117). A part of the first part (1161) of the second hotline (116) can be drawn out through the drawing part (1451) of the cover member (142). The drawing part (1451) can be provided on one side of the cover member (142) covering 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) can be meant. As an example of one side of the cover member (142), the central part of the cover member (142) can be meant. The drawing part (1451) can be formed to penetrate one side of the cover member (142). The drawing part (1451) can be connected to be in communication with the machine room (117).

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 withdrawn 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).

The downstream side of the first portion (1161) of the second hot line (116) may extend in the first direction and/or may extend in a second direction different from the first direction to penetrate the withdrawal portion (1451) and/or may be connected to the upstream side of the first side (1151) of the first hot line (115).

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).

The downstream side of the fifth side (1155) of the first hot line (115) may be extended in the second direction and/or may be bent in the first direction different from the second direction to pass through the withdrawal portion (1451) and/or may be connected to the upstream side of the second part (1162) of the second hot line (116).

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).

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).

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 part (1451) of the cover member (142).

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/or another part of the second part (1162) of the second hot line (116) may extend in a second direction different from the first direction along the third cover (1173). In this case, it is easy for the inclined part of the first part (1161) of the second hot line (116) to avoid interference with other cycle components, such as a printed circuit board (130).

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 a corner where one of the first covers (1171a, 1171b) (1171a) and the third cover (1173) meet.

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

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) to connect 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.

The first panel (101a, 101b) is composed of a vacuum insulator. The second plate (133a, 133b) constituting the vacuum insulator can extend in a first direction. Here, the first direction can be the X-axis direction. A folded portion (134) can be provided on one side of the second plate (133a, 133b). Here, the one side can 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 folded portion (134) is formed to be folded in a second direction different from the first direction on one side of the second plate (133a, 133b). Here, the second direction can be the Y-axis direction.

According to this configuration, the bending portion (134) improves the strength of the vacuum insulation panel, thereby preventing distortion of the panel shape due to vacuum and high-temperature exhaust during the production of the vacuum insulation panel.

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

The bending portion (134) is arranged 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.

The length of the second direction extension of the folded portion (134) may be formed smaller than the side length of the vacuum space. The second direction extension length of the folded portion (134) may be formed smaller than the gap between the second plates (133a, 133b) and the first plates (132a, 132b). It is preferable that the length of the folded portion (134) be about half the side length of the vacuum space.

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

The drawer guide (137) may be arranged apart from the first plate (132a, 132b). Optionally, the drawer guide (137) may not be provided in the first storage room (106) but may be provided in the second storage room (107). The drawer guide (137) may guide the drawer to be introduced into or withdrawn from the interior of the main body (100).

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

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) may reinforce the insulation performance of the vacuum insulation body that insulates heat leakage between the outside and inside of the chamber. 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) may have the effect of insulating heat leakage between the outside and inside of the chamber.

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).

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) may reinforce the strength of the thin first plate (132a, 132b) and/or prevent a part of the first plate (132a, 132b) from being warped.

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.

Optionally, a second insulation material (138b) may be provided between the folded portion (134) and the side plates (135a, 135b). The second insulation material (138b) may be composed of polyurethane foam. Through this, 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 folded portion (134) and the side plates (135a, 135b).

The first hot line (115) may be arranged to be connected to the bending portion (134). The bending portion (134) may be made of a metal material together with the second plate (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. Through this, the effect of preventing surface condensation may be obtained.

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

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).

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).

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

The first hotline (115) may be placed at a corner where the second plate (133a, 133b) of the first panel (101a, 101b) and the first side of the door meet. Here, the second plate (133a, 133b) of the first panel (101a, 101b) may form the left side of the refrigerator. The first side of the door may form the left side of the door.

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 at least one of the first support plate (1361a, 1361b), the bar (1363a, 1363b), and the 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) and supports one surface of the second plate (133a, 133b).

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

A portion of the door may be made of vacuum insulation. Another portion of the door may be made of an insulating block (141) which 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 arranged toward one side (e.g., the outer side) of the main body (100). Another portion of the door made of non-vacuum insulation is arranged toward one side (e.g., the inner side) of the main body (100).

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

FIG. 16 is a conceptual diagram showing a hotline (114) according to the present invention being coupled to a cover member (142) and/or connected to one side (e.g., the outer side) of a bent portion (134) of a second plate (133a, 133b).

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 make it look good. Accordingly, the cover member (142) can be named a front decoration following the front of the decoration in that it makes the appearance look good and/or is arranged on the front of the main body (100).

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

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 manufactured separately and then coupled to the cover member (142). In the present embodiment, the hotline receiving portion (146) is shown as being formed integrally with the cover member (142).

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 part 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 part of the first plate (132a, 132b) of the insulation or a part of the first insulation material (138a).

The cover member (142) may be composed of a first cover member (142a) and/or a second cover member (142b). The first cover member (142a) extends in one direction parallel to the first plate (132a, 132b) so as to surround a portion of the first plate (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).

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

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 projection. 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 projection 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, and conversely, a coupling groove may be formed on the first coupling portion (143) and/or a hook or projection may be formed to protrude on the drawer guide (137).

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/or a second wall (1463) that protrude from the second cover member (142b) toward the folded 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 form the same plane as the second plate (133a, 133b).

A bend (1462) may be formed at an end of the first wall (1461). The bend (1462) may enhance the strength of the hotline receiving portion (146). The bend (1462) may be connected to the first hotline (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 shorter than the bend (134). Through this, the bend (1462) may restrict the movement of the first hotline (115).

The second wall (1463) is arranged toward one side (e.g., the inner side) 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 projection. In the present embodiment, the second connecting portion (1464) is shown as being formed in the form of a hook.

An accommodation hole may be formed to penetrate in one direction so that a hot line (114) can be accommodated between the first wall (1461) and the second wall (1463). The accommodation hole faces the folded portion (134). When the cover member (142) is combined with one surface of the main body (100), the accommodation hole may be covered by the folded portion (134).

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 inner side) of the door when the door is opened or closed.

The cover member (142) can be coupled with a magnet (147) to secure a close force 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 attractive force, thereby providing a close force between the door and the main body (100) when the door is closed.

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

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/or a hot line (114) arranged on one side (e.g., the inner side) of a bent portion (134) of a second plate (133a, 133b).

This embodiment is different 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., the inner side) of the bending portion (134).

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

An outer casing (140) may be arranged 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 “woolly”) when exhausting air from the vacuum space.

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 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) may increase the strength of the first plate (132a, 132b), thereby preventing the first plate (132a, 132b) from being distorted when air in the vacuum space is exhausted. When insulation is filled on one surface (e.g., the outer surface) of the first plate (132a, 132b), the inner casing (139) may be easily filled with insulation even without a drawer guide (137).

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

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 from the other side of the hotline receiving portion (205) toward the side plates (135a, 135b). Here, an example of the first direction may refer to the X-axis direction. Through this, the first support portion (206) may be in 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.

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 in close contact with the one side and the other side of the hotline (114), thereby restricting the hotline (114) from moving in the first direction.

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., an inner surface) of the second plate (133a, 133b) and/or an outer surface of the side plates (135a, 135b). Through this, a part of the hotline receiving portion (205) is in close contact with 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.

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.

A coupling projection (203) may be provided on one side (e.g., the inner side) of the cover member (200). The coupling projection (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 projection (203) may be coupled by penetrating the coupling hole (208). The coupling projection (203) and the coupling hole (208) may be coupled by a force fit.

The protrusion 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), the first plate (132a, 132b), and/or the side plate (135a, 135b). 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 insulator can be strengthened.

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

One side of the first cover member (142a) can be adhered 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 to be in close contact with and/or adhered to each other.

A protrusion (204) may be formed on one side (e.g., the inner side) of the second cover member (142b). The protrusions (204) may be provided in multiple numbers. At least one or two first protrusions (204) among the protrusions (204) are configured to support another part of the hotline receiving portion (205). Here, the other part of the hotline receiving portion (205) protrudes and extends from one side (e.g., the inner side) of the folded portion (134) toward the first cover member (142a). Through this, not only can a supporting force be secured for another part of the hotline receiving portion (205) that is not overlapped with the folded portion (134), but there is also an advantage in that the hotline receiving portion (205) and the cover member (200) can be easily combined.

Among the protrusions (204), at least one or 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 second protrusions (204) are arranged to be connected to the bending portion (1401) of the outer casing (140). A magnet (147) may be coupled between the first protrusion (204) and the second protrusion (204).

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

Figure 18 shows a hotline receiving portion (303) and a bending portion (301) coupled together according to another embodiment of the present invention.

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).

The hotline receiving portion (303) is arranged on one side (e.g., the inner side) of the bending portion (301). The first support portion (304) and/or 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) interposed 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 member (304) and/or the second plate (133a, 133b) can limit the hot line (114) from moving in the Y-axis direction.

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 mean, for example, the Y-axis direction. The second support portion (305) faces the bend portion (301) with the hotline (114) interposed 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/or the bend portion (301) may restrict the hotline (114) from moving in the X-axis direction.

A joining hole is formed to penetrate the bending portion (301). A joining member such as a screw can pass through the joining hole and be joined to a hotline receiving portion (303) to be described later.

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) on the other side of the hotline receiving portion (303). Here, the first direction may mean the X-axis direction as an example.

A female screw portion may be formed on one side (e.g., the inner side) of the boss portion (306). The female screw portion is coupled with the screw. Through this, a coupling member such as a screw is coupled to the boss portion (306), so that the bend portion (301) and the hot line receiving portion (303) can be coupled to each other. The cover member (300) can be coupled to the bend portion (301) through the hot line receiving portion (303).

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

Figure 19 is a conceptual diagram showing a hotline receiving portion (403) and a bending portion (401) coupled together according to another embodiment of the present invention.

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/or the hotline receiving portion (403) is coupled to the bending portion (401).

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

A part of the bend portion (401) is further extended to protrude in a second direction so as not to overlap with the bend portion (411) of the outer casing (410) and/or to overlap with a part of the hotline receiving portion (403). Here, the second direction may refer to the Y-axis direction as an example. The extension length of the bend 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. A coupling hole (402) may be formed to penetrate through the bend 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 hotline receiving portion (403). The coupling protrusion (405) may penetrate through the coupling hole (402) and be coupled to the bend portion (401). The joining projection (405) and/or the bending portion (401) can be joined by force fitting through the joining hole (402).

The hotline receiving unit (403) is placed on one side (e.g., the outer side) of the bending unit (401).

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

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).

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

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).

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

A second receiving hole is formed toward one side (for example, the outer side) of the folded portion (401) between the third receiving wall (408) and the first receiving wall (406). A magnet (408) can be received and coupled through the second receiving hole.

The second cover member (415) may be extended from one side of the first cover member (413) to cover the first receiving hole and/or the second receiving hole. One side of the second cover member (415) may be provided with a bending portion (411) 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.

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

One side of the hotline receiving portion (403) may be connected to or supported by the outer casing (410) and/or the bending portion (401).

One side of the hotline receiving portion (403) may be arranged between the second cover member (415) and the outer casing (410). One side of the hotline receiving portion (403) may be arranged between the second cover member (415) and the folded portion (401). Through this, the hotline (114) is not connected to the outer casing (410) and/or the folded portion (401) by one side of the hotline receiving portion (403). When the hotline (114) is connected to the outer casing (410) or the folded 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 folded portion (401) through the hotline (114), which may increase heat loss.

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

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

Since other configurations are identical or similar to those of the embodiments of FIGS. 1 to 18, duplicate descriptions will be omitted.

Figure 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.

A protruding wall is provided on one side (e.g., inner side) of the second cover member (503). The protruding wall may include a first protruding wall (504) and/or a second protruding wall (506). The first protruding wall (504) is formed to protrude in one direction toward the side plates (135a, 135b). The second protruding wall (506) 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).

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 sunken in the protruding direction of the joining portion (502) on one side of the drawer guide (508).

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

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

Figure 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.

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).

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).

Due to this, 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).

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).

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