Abstract

Disclosed is a refrigerator. The refrigerator comprises: a main body having a storage chamber therein; and a machine chamber disposed on one side of the main body. The storage chamber of the main body is formed between a first panel, a second panel, a third panel, and a fourth panel which form a first surface, a second surface, a third surface, and a fourth surface of the refrigerator, respectively. The fourth panel delimits the storage chamber and the machine chamber. The first panel and the second panel are made of a vacuum insulator, and the fourth panel is made of a non-vacuum insulator. Accordingly, even if the fourth panel does not separately have a corrugated pipe structure and a sealing penetration structure, a penetrating component may penetrate from the storage chamber to the machine chamber through a penetration portion formed to penetrate inside the fourth panel, which is a non-vacuum insulator, so as to penetrate in the Z-axis direction.

Description

Insulator

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

Korean Patent No. 10-1960320 (announced on July 15, 2019, hereinafter referred to as “Patent Document 1”) discloses a refrigerator having a connecting pipe of a corrugated pipe structure in a vacuum space between an inner case and an outer case. According to the disclosure in Patent Document 1, both ends of the connecting pipe are connected to the communication port of the inner case and the communication port of the outer case in the vacuum space. The connecting pipe is formed of a metal sheet, and the side wall of the connecting pipe is formed of a bellows-type corrugated structure. Accordingly, the connecting pipe not only forms a passage through which a pipe passes through the vacuum space, but also maintains strength to maintain the airtightness of the vacuum space by being elastically deformable, and can withstand the vacuum pressure of the vacuum space. Since the connecting pipe of Patent Document 1 penetrates a vacuum insulator, sealing is required to prevent vacuum leakage. In order to manufacture such a penetrating structure requiring sealing, the assembly process is complicated, and since an airtight connection such as welding is required, there is a problem of reduced manufacturability.

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

The first purpose is to provide a refrigerator in which the sealed penetration structure required in the fourth panel of a vacuum insulator can be changed to a simple penetration structure when forming a penetration structure for the wiring of various parts of a storage room or water generated in an evaporator to penetrate the fourth panel.

The second purpose is to provide a refrigerator capable of forming a fourth panel of a three-dimensional shape.

The third purpose is to provide a refrigerator having a structure that makes it easy to manufacture the fourth panel, improves manufacturability, and reduces manufacturing costs.

The fourth objective is to provide a refrigerator having a structure that can minimize heat leakage at the corners of the panel.

The present invention may include a main body that forms an exterior of a refrigerator and/or provides a support between a first plate and a second plate to maintain a vacuum space. A machine room arranged in the main body may be provided. A fourth panel that partitions a storage room formed inside the main body and the machine room may be provided. A fourth panel formed by filling a non-vacuum insulation material between a first cover and a second cover may be provided. The first plate and the second plate may be composed of a metal material, and/or the non-vacuum insulation material may be composed of polyurethane foam.

Optionally, the fourth panel may include a first through-hole portion that receives and/or surrounds a drain pipe through which the water generated in the storage room flows toward the machine room. The refrigerator according to claim 1, wherein the fourth panel includes a second through-hole portion that receives and surrounds an electric wire or signal line that penetrates in both directions between the storage room and the machine room.

In the present invention, at least one of a second panel forming a second surface of the refrigerator and a first panel forming one of the first surfaces of the refrigerator may be provided. Another one of the first panels forming the other of the first surfaces of the refrigerator may be provided. The first panel may form a storage compartment together with the second panel. An exhaust port formed to protrude may be provided on at least a portion of the first and second panels. An exhaust port receiving portion may be concavely formed on at least one of the rear surface, the left surface and the right surface of the fourth panel, which is arranged to face the second panel, one of the first panels and the other of the first panels, respectively.

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

First, the main body forming the exterior of the refrigerator is composed of vacuum insulation, while the fourth panel dividing the main body and the machine room is composed of non-vacuum insulation. The vacuum insulation forms a vacuum space with a certain gap between the first plate and the second plate. The non-vacuum insulation is formed by filling polyurethane foam between the first cover and the second cover.

Through this, since the application of a general penetration structure to the fourth panel, which is a non-vacuum insulating body, is possible, the corrugated pipe structure and sealed penetration structure of the prior patent are unnecessary, and a penetration part can penetrate from a storage room formed inside the main body to a machine room arranged on one side of the main body through the penetration formed in the fourth panel.

Therefore, it has a simple structure, making it easy to manufacture and greatly contributing to reducing manufacturing costs. The penetration part of the fourth panel, which is a non-vacuum insulation body, can efficiently prevent cold air leakage and perform insulation with a simple structure by wrapping the penetration part.

For example, if the penetration portion is simply formed to penetrate the fourth panel in the Z-axis direction, penetration components such as a drain pipe for draining the water, a cycle pipe of the refrigeration cycle device, and a harness for electric wiring and signal lines are surrounded by the penetration portion, so that insulation can be formed between the penetration components and the storage room without a separate corrugated pipe structure, and since the fourth panel is a non-vacuum insulator, a separate sealed penetration structure is unnecessary.

First, the exhaust port for vacuum exhaust of the vacuum insulation panel can be surrounded and accommodated by one side of the fourth panel, which is a non-vacuum insulation panel. An exhaust port accommodation portion is formed on the third side, the first side, and/or the second side of the fourth panel. Through this, the exhaust port accommodation portion is formed to be sunken in the general groove shape of the fourth panel, so that it is easy to manufacture with a simple structure and the manufacturing cost can be reduced.

Second, the fourth panel includes a first block portion, a third block portion, a fourth block portion, and/or an insulation reinforcement portion. The first block portion is configured to partition a storage room and a machine room of the main body. The second block portion may be formed to protrude in one direction from the first block portion. The third block portion and/or the fourth block portion may be formed to protrude in one direction from one side and the other side of the first block portion. In addition, the insulation reinforcement portion may be formed to protrude in the other direction from the other surface of the first block portion.

Through this, the fourth panel can improve the insulation performance by increasing the thickness or height of specific portions, i.e., the third side, the first side, the second side and/or the third side.

The fourth panel not only blocks heat leakage at the corner portion where at least two panels are connected to each other through the second block portion, the third block portion, and/or the fourth block portion, but also improves insulation performance without reducing the internal volume through the insulation reinforcement portion.

Third, a support frame is coupled to the bottom surface of the fourth panel. A first coupling portion and a second coupling portion are provided at each end of the support frame. The first coupling portion is configured to couple the support frame and the side panel. The second coupling portion is configured to couple the support frame and the side cover of the machine room. Accordingly, the support frame is coupled to the side panel through the first coupling portion and/or coupled to the upper portion of the side cover of the machine room through the second coupling portion, thereby firmly supporting the fourth panel. The support frame is not only easy to assemble with the fourth panel, which is a non-vacuum insulator, and the side panel of the main body, which is a vacuum insulator, but also can support the fourth panel and the load applied to the fourth panel with a simple structure without adopting a corrugated pipe structure and a sealed penetration structure.

In addition, since both ends of the support frame are connected to the first panel and the second panel through the first connecting portion, the fourth panel can be closely attached to the first panel and the second panel.

Fourth, the support frame can be made of a metal material. The support frame can be provided in multiple pieces to support the load of the main body. At least two support frames can be arranged to be spaced apart from at least one of the first and second sections of the fourth panel. Through this, it is possible to minimize leakage of cold air from the second storage room through the support frame from the first and second sections of the fourth panel.

Fifth, since a soft insulation material is provided between the fourth panel, which is a non-vacuum insulation body, and the main body, which is a vacuum insulation body, not only is the seal between the fourth panel and the main body easy, but also the leakage of cold air can be prevented.

Sixth, a penetration portion is formed so that a drain pipe through which the water is discharged passes through the central portion of the fourth panel. The penetration portion for the water is formed so as to pass through the central portion of the second block portion, the first block portion, and/or the insulation reinforcement portion in the Z-axis direction.

The recessed portion is formed to be inclined at a preset angle toward the upper portion of the water penetration portion in the second block portion, so that the water can be drained smoothly.

By forming the water drain pipe to penetrate the second block section, the first block section, and/or the insulation reinforcement section, the length of the heat transfer path increases, thereby minimizing heat leakage through the water drain pipe.

Seventh, a front plate can be joined to one side of the fourth panel. Both ends of the front plate are joined to the side panels, so that the fourth panel can be tightly joined to the third panel of the main body.

A drain (116) is formed in the center of the bottom wall so as to penetrate in the Z-axis direction. The bottom wall may be formed so as to slope downward from the side wall toward the drain (116). Accordingly, the water does not remain in the sump (115) and can be effectively discharged through the drain (116).

A drain pipe (117) is connected to the bottom wall. The drain pipe (117) is connected to be in communication with the drain port (116) and/or extends in the Z-axis direction and passes through the fourth panel (104) described later to be connected to the machine room (119). Through this, the defrost water can move to the machine room (119) through the drain pipe (117).

A compressor cover (121) may be installed to cover one side of the compressor (120). For example, the compressor cover (121) may be configured to cover at least a portion of the compressor (120). The compressor (120) may be accommodated inside the compressor cover (121). At least one side of the compressor cover (121) may be formed to be open.

A condenser cover (123) may be installed to cover one side of the condenser. For example, the condenser cover (123) may be configured to cover at least one side of the condenser. The condenser may be accommodated inside the condenser cover (123). At least one side of the condenser cover (123) may be formed to be open.

A cooling fan (122) may be placed between the compressor (120) and the condenser. The cooling fan (122) is configured to provide power to air. The cooling fan (122) is configured so that the flow direction of the outside air flows in one direction. In the present embodiment, the cooling fan (122) is configured so that the outside air passes through the cooling fan (122) from the compressor (120) and flows to the condenser.

An intake port (1194) may be formed in the first side cover (1193). An exhaust port may be formed in the second side cover (1193). The intake port (1194) and the compressor (120) may be spaced apart in the Y-axis direction and/or may be arranged to face each other. The condenser and the exhaust port may be spaced apart in the Y-axis direction and/or may be arranged to face each other.

The size of the intake port (1194) may be formed to correspond to the Y-axis direction open area of the compressor cover (121). The size of the exhaust port may be formed to correspond to the Y-axis direction open area of the condenser cover (123). The intake port (1194) and the exhaust port may be formed in the shape of a louver. At least one of the intake port (1194) and the exhaust port may be provided with a through hole extending in the Z-axis direction.

According to this, the cooling fan (122) sucks in outside air through the intake port (1194). The sucked air can cool the compressor (120) by exchanging heat with the compressor (120) while passing through the compressor (120). The air passing through the compressor (120) can cool the condenser by exchanging heat with the condenser while passing through the cooling fan (122). Subsequently, the air passing through the condenser can be discharged to the outside through the exhaust port.

Both ends of the compressor cover (121) are connected to the intake port (1194) and the cooling fan (122). The compressor cover (121) can serve as an air path. The compressor cover (121) extends in the Y-axis direction. The compressor cover (121) can transfer air introduced through the intake port (1194) to the cooling fan (122). The compressor cover (121) not only guides the air flow direction to the compressor (120), but also can restrict the air from spreading in the X-axis direction and the Z-axis direction by wrapping at least one surface of the compressor (120).

The condenser cover (123) is connected to the cooling fan (122) and/or the exhaust port. The condenser cover (123) can act as an air path. The condenser cover (123) extends in the Y-axis direction. The condenser covers (123) are arranged to overlap in the Y-axis direction. The condenser cover (123) can transfer air passing through the cooling fan (122) to the exhaust port. The condenser cover (123) not only guides the air flow direction to the condenser, but also can restrict the air from spreading in the X-axis direction and the Z-axis direction by covering at least one side of the condenser.

The compressor (120), the compressor cover (121), the cooling fan (122), the condenser, and the condenser cover (123) can be aligned in the Y-axis direction at the center of the X-axis direction of the machine room (119). The compressor cover (121), the cooling fan (122), and the condenser cover (123) can be arranged to be spaced apart from the front cover (1191) and the back cover (1192) in the X-axis direction.

Figure 12 is an exploded view showing the fourth panel (104) in Figure 11 separated into a first cover (124), an insulating material (125), and a second cover (126).

Fig. 13 is a conceptual diagram showing the exhaust port receiving portions (1391, 1392, 1393) formed on the rear (a, d) and left and right sides (b, c, d) of the fourth panel (104) in Fig. 12. Fig. 20d is a cross-sectional view taken along XX-XX in Fig. 20a.

Figure 14 is a conceptual diagram showing a foam injection port (1262) formed on the bottom surface of the fourth panel (104) in Figure 13.

The fourth panel (104) is formed to separate the storage room and the machine room (119) of the main body (100). The fourth panel (104) forms one side of the main body (100). The fourth panel (104) may also form one side of the machine room (119).

The fourth panel (104) is composed of polyurethane foam (hereinafter, abbreviated as PU foam).

The fourth panel (104) includes a first cover (124), a second cover (126) and/or insulation (125).

The first cover (124) and the second cover (126) form the outer shape of the fourth panel (104). The first cover (124) and the second cover (126) may be made of a plastic material. The first cover (124) and the second cover (126) may be formed by injection molding.

An insulating material (125), such as PU foam, may be formed by foaming between the first cover (124) and the second cover (126). The first cover (124) is formed to cover the upper part of the insulating material (125). The second cover (126) is formed to cover at least a portion of the insulating material (125).

The first cover (124) and the second cover (126) can be connected to each other by an adhesive means such as an adhesive. However, in addition to the adhesive means, the first cover (124) and the second cover (126) can be connected by various connecting means such as a screw connection by a screw or a snap fit connection by a hook.

The fourth panel (104) includes at least one of the fourth block portion (127), the second block portion (128), one of the first block portions (131), the other of the first block portions (132), and the insulation reinforcement portion (135). Depending on the shape and structure of the fourth panel (104), specific parts of the fourth panel (104) may be named the fourth block portion (127), the second block portion (128), one of the first block portions (131), the other of the first block portions (132), and the insulation reinforcement portion (135).

However, at least one of the fourth block portion (127), the second block portion (128), one of the first block portions (131), the other of the first block portions (132), and the insulation reinforcement portion (135) may form a part of at least one of the first cover (124), the insulation material (125), and the second cover (126).

The fourth block portion (127) is formed to extend in the X-axis direction and the Y-axis direction. The fourth block portion (127) can have a constant thickness in the Z-axis direction between the first surface and the second surface. The fourth block portion (127) can partition the second storage room (106) and the machine room (119).

On one side of the fourth block portion (127), a door mounting groove (1271) may be formed concavely in one direction (e.g., rearward). The door mounting groove (1271) may extend in the Y-axis direction. The door mounting groove (1271) is configured to receive a portion of the second storage compartment door when the second storage compartment door is closed. Accordingly, since a portion of the second storage compartment door and a portion of the fourth panel (104) are arranged to overlap each other in the Z-axis direction, the insulation performance between the second storage compartment door and the main body (100) may be improved.

The second block portion (128) is formed to protrude in one direction from the fourth block portion (127). The second block portion (128) extends along the Y-axis direction of the fourth block portion (127).

The second block part (128) is placed at the corner where the fourth panel (104) and the second panel (101) meet. The second block part (128) not only connects the fourth panel (104) and the second panel (101), but also blocks heat leaking through the corner of the connected panels.

The surface of the second block portion (128) is arranged to face the second panel (101) in the X-axis direction and overlap with it. Through this, the second block portion (128) and the second panel (101) can double-block heat leakage through the overlapping structure of the non-vacuum insulation material (125) and the vacuum insulation.

A mounting portion (1281, 1282), a recess portion (1283), and/or a drainage groove (1286) are provided on one surface of the second block portion (128). The mounting portion is formed in a rectangular plane shape. A part of the second storage joint (111) is mounted and connected to the mounting portion, and/or the second storage joint (111) is supported by the mounting portion. The mounting portion may be composed of a first mounting portion (1281) and a second mounting portion (1282).

The first anchoring portion (1281) is placed on the second block portion (128). The first second storage joint (111a) connecting one of the first panels (1031) and the second panel is placed on and supported by the first anchoring portion (1281).

The second fixing portion (1282) is positioned at the right end of the second block portion (128). The second second storage joint (111b) connecting the other one of the first panels (1032) and the second panel (101) is supported by being fixed to the second fixing portion (1282).

A portion of the return duct may be mounted and/or supported on at least one of the first mounting portion (1281) and the second mounting portion (1282). The return duct forms a path for cold air to be returned from the first storage room (105) to the second storage room (106).

The penetration portion (129) is formed to penetrate the fourth panel (104) in the Z-axis direction. The penetration portion (129) accommodates a penetration component so that the penetration component can penetrate the fourth panel (104). The penetration component may include a drain pipe (117) and wiring such as an electric wire.

The penetration portion (129) may be composed of a first penetration portion (1291) and a second penetration portion (1292). The first penetration portion (1291) accommodates a drain pipe (117) of the sump (115). The first penetration portion (1291) may be formed to correspond to the shape of the drain pipe (117). In this embodiment, the first penetration portion (1291) is shown as being formed in a circular tube shape.

The recessed portion (1283) is arranged between the first anchoring portion (1281) and the second anchoring portion (1282). The recessed portion (1283) is formed to be inclined at an angle corresponding to the bottom wall of the sump (115). The recessed portion (1283) may be connected to one side of the bottom wall and/or may support the sump (115). Through this, the recessed portion (1283) may guide the flow of the defrost water together with the bottom wall of the sump (115) to the drain (116), thereby facilitating the drainage of the defrost water.

A drainage groove (1286) is formed in the center of the recess (1283). The recess (1283) includes a first recess (1284) formed to slope downward from the first fixing portion (1281) to the drainage groove (1286), and a second recess (1285) formed to slope downward from the second fixing portion (1282) to the drainage groove (1286).

The drainage groove (1286) is formed to be sunken in one direction (e.g. downward) in a part (e.g. bottom) of the recessed portion (1283). The first penetration portion (1291) is formed to penetrate the Z-axis direction of the second block portion (128) in the drainage groove (1286). The first penetration portion (1291) may also be formed to be able to penetrate the insulation reinforcement portion (135) described later.

Through this, the drain pipe (117) can be accommodated in the first penetration portion (1291) and/or can penetrate the fourth panel (104) through the first penetration portion (1291). The first penetration portion (1291) can wrap around the drain pipe (117) to minimize heat leakage through the drain pipe (117).

The second penetration portion (1292) accommodates a pipe having wires or other wiring embedded therein. The pipe may be formed into a corrugated pipe structure that is adjustable in length or easily bendable.

The second penetration portion (1292) can be formed in the first fixing portion (1281) or the second fixing portion (1282). In the present embodiment, the second penetration portion (1292) is formed to penetrate in the Z-axis direction from the corner of the second fixing portion (1282). The second penetration portion (1292) has a rectangular cross-sectional shape smaller than the rectangular area of the second fixing portion (1282). The cross-sectional shape of the second penetration portion (1292) is not limited to a rectangular shape and can be formed in various shapes such as a circle.

The second penetration portion (1292) can also be formed to penetrate the insulation reinforcement portion (135) described later.

Through this, the pipe can be accommodated in the second penetration portion (1292) and/or can pass through the fourth panel (104) through the second penetration portion (1292). The second penetration portion (1292) can wrap around the pipe to minimize heat leakage through the pipe.

One of the first block parts (131) and the other of the first block parts (132) are formed to extend in the Z-axis direction and the X-axis direction. One of the first block parts (131) and the other of the first block parts (132) have a thickness in the Y-axis direction between one side facing the storage room and one side facing the opposite side.

One of the first block portions (131) and the other of the first block portions (132) are positioned at an edge where the fourth block portion (127) meets one of the first panels (1031) and the other of the first panels (1032). One of the first block portions (131) and the other of the first block portions (132) can extend in one direction (e.g., forward) from both ends of the second block portion (128). One of the first block portions (131) and the other of the first block portions (132) can extend in one direction from an end of the fourth block portion (127). The Z-axis height of one of the first block parts (131) and the other of the first block parts (132) may be formed to be smaller than the X-axis length of one of the first block parts (131) and the other of the first block parts (132), and may be formed to be longer than the Y-axis thickness of one of the first block parts (131) and the other of the first block parts (132).

One of the first block parts (131) is positioned to face one of the first panels (1031) in the Y-axis direction. Another one of the first block parts (132) is positioned to face another one of the first panels (1032) in the Y-axis direction.

A door side mounting groove (133) is formed in one of the first block portions (131) and the other of the first block portions (132). The door side mounting groove (133) is formed concavely in the Y-axis direction on one surface of one of the first block portions (131) and the other of the first block portions (132) so that when the second storage compartment door is closed, the side of the second storage compartment door is received on one surface of one of the first block portions (131) and the other of the first block portions (132).

One side of the door side mounting groove (133) may be formed to be inclined in the X-axis direction. The concave depth in the Y-axis direction may increase from the first stage to the second stage of the door side mounting groove (133).

Through this, when the second storage room door is closed, the interference between one of the first block parts (131) and the other of the first block parts (132) and a part (e.g., the left and right sides) of the second storage room door can be reduced, thereby minimizing resistance. A part (e.g., the left and right sides) of the second storage room door is formed of a rubber material capable of elastic deformation, so that a seal can be formed between the second storage room door and the main body (100).

In addition, the insulation material (125) of a part of the second storage room door and one of the first block parts (131) and the other of the first block parts (132) is arranged to overlap each other, thereby preventing heat from leaking through the gap between the second storage room door and the main body (100).

A drawer entry portion (134) is formed on one side (e.g., rear) of the door side mounting groove (133). The drawer entry portion (134) is formed concavely in the Y-axis direction on one side of the side block so that when the second storage drawer is closed, the side of the second storage drawer is received on one side of one of the first block portions (131) and the other side of the first block portions (132).

The drawer entry portion (134) is formed to protrude further in the Y-axis direction than the door side fixing groove (133), so that the stop position of the second storage drawer can be limited by being caught when the second storage drawer is closed.

One of the first panels (1031) and the other of the first panels (1032) can be configured to surround one of the first block portions (131) and the other of the first block portions (132) of the fourth panel (104). One of the first panels (1031) and the other of the first panels (1032) and one of the first block portions (131) and the other of the first block portions (132) can be arranged to overlap each other in the Y-axis direction. Through this, one of the first panels (1031) and the other of the first panels (1032), which are vacuum insulators, and one of the first block portions (131) and the other of the first block portions (132), which are non-vacuum insulators, can double-block heat leakage.

One of the first block portions (131) of the fourth panel (104) and the other of the first block portions (132) may be attached to one of the first panels (1031) and the other of the first panels (1032) in the Y-axis direction by a contact frame or may be joined to one of the first panels (1031) and the other of the first panels (1032) by using a bolt plate. In this embodiment, one of the first block portions (131) and the other of the first block portions (132) are shown attached to one of the first panels (1031) and the other of the first panels (1032) by a contact frame.

The sealing frame may be formed to extend in the Z-axis direction. The sealing frame may be configured to seal the second storage room insulation blocks (112a, 112b) located on one side of one of the first block portions (131) and the other of the first block portions (132) of the fourth panel (104) toward one of the first panels (1031) and the other of the first panels (1032) in the Y-axis direction.

The close-fitting frame may be composed of a first close-fitting frame and a second close-fitting frame. The first close-fitting frame is arranged to be spaced apart from one end of one of the first block portions (131) and the other end of the first block portion (132) by a first interval. The second close-fitting frame is arranged to be spaced apart from one direction (e.g., rearward) of the first close-fitting frame. The second close-fitting frame may be arranged at a corner where one end of one of the first block portions (131) and the other end of the first block portion (132) and the end of the second block portion (128) meet.

A frame joining groove (1301, 1302) is formed concavely in the Y-axis direction on one surface of one of the first block portions (131) and the other surface of the first block portion (132). The frame joining groove (1301, 1302) can extend in the Z-axis direction. A sealing frame can be inserted into and joined to the frame joining groove (1301, 1302).

An exhaust port receiving portion (1391, 1392, 1393) is formed to protrude to one side in the rear cover (1264), the first side cover (1265), and/or the second side cover (1266). A foaming liquid injection port (1262) is formed to penetrate in the Z-axis direction at the center of the cover (1261).

The polyurethane foam liquid can be injected into the internal space of the first cover (124) and the second cover (126) through the foam liquid injection port (1262) and then foamed. Through this, the fourth panel (104) is foam-molded using polyurethane foam material, so that the first penetration portion (1291) and the second penetration portion (1292), etc. can be easily formed in the non-vacuum insulation body without having to maintain a vacuum state.

The fourth panel (104) can be supported on one side of the machine room (119) by a support frame (140). The fourth panel (104) can form the upper part of the machine room (119).

The support frame (140) is connected to one side of the machine room (119). The support frame (140) is arranged to be spaced apart from one side of the fourth panel (104) in the X-axis direction, and is configured to support one side of the fourth panel (104).

The support frame (140) is arranged between one of the first panels (1031) and the other of the first panels (1032). The support frame (140) may extend in the Y-axis direction along one side of the fourth panel (104). The support frame (140) is manufactured using a metal material and has rigidity for supporting the load of the main body (100). The support frame (140) may have a “ㄷ” cross-sectional shape.

For example, the support frame (140) includes a first portion (144) and at least two second portions (145). The first portion (144) is arranged to face one side of the fourth block portion (127) in the Z-axis direction so as to be connected. The first portion (144) extends in the Y-axis direction between one of the first panels (1031) and the other of the first panels (1032).

The first part (144) is formed in a plate shape extending in the X-axis direction and the Y-axis direction. The first part (144) is formed so that the length in the Y-axis direction is longer than the width in the X-axis direction. A joining hole (1441) is formed to penetrate the first part (144) in the Z-axis direction. The joining holes (1441) are arranged to be spaced apart from each other in the Y-axis direction of the first part (144). Through this, a joining member such as a screw can join the support frame (140) and the fourth panel (104) through the joining hole (1441) of the first part (144).

The second part (145) is formed to protrude in one direction from the first and second ends of the first part (144).

One end of the Y-axis direction of the first connecting portion (146) can be arranged to be connected to the Y-axis direction side of the fourth block portion (127). Through this, the first connecting portion (146) can restrict the support frame (140) from moving in the Y-axis direction in the fourth block portion (127).

The X-axis length of the first coupling portion (146) is longer than the X-axis width of the first portion (144). The X-axis center of the first coupling portion (146) may be coupled so as to be offset in one direction (e.g., rearward) from the X-axis center of the first portion (144). One end of the first coupling portion (146) may be arranged close to the end of the support frame (140).

The first connecting portion (146) is positioned to face one of the first panels (1031) and/or a portion of the other of the first panels (1032) in the Z-axis direction. A first connecting hole (1461) is formed to penetrate in the Z-axis direction through at least one of the first end and the second end of the first connecting portion (146). Through this, the first connecting portion (146) can be connected to one of the first panels (1031) and/or the other of the first panels (1032) by a connecting member such as a screw.

A plate extension (1371) (see FIG. 27) is provided on one of the first panels (1031) and/or the other of the first panels (1032) made of a vacuum insulation material. The plate extension (1371) is formed to extend from the first plate (137) of one of the first panels (1031) and/or the other of the first panels (1032).

The plate extension (1371) may be formed to be bent in one direction (e.g., vertically). The plate extension (1371) may be composed of a first plate extension (1372) extending in the Z-axis direction from the first plate (137) of one of the first panels (1031), the other of the first panels (1032), and/or a second plate extension (1373) extending in the Y-axis direction from the first plate extension (1372).

The first connecting portion (146) is positioned to face the second plate extension portion (1373) in the Z-axis direction. The first connecting portion (146) can be connected to the second plate extension portion (1373). Through this, the support frame (140) can be connected to one of the first panels (1031) and/or the other of the first panels (1032) by the first connecting portion (146).

The second connecting portion (147) is formed to connect the support frame (140) and the side cover (1193) of the machine room (119). The second connecting portion (147) extends from one end of the Y-axis direction of the first connecting portion (146) in the X-axis direction and one direction (e.g. downward). The second connecting portion (147) may be formed in a plate shape in which the length in the X-axis direction is longer than the width in the Z-axis direction.

The first coupling part (146) and the second coupling part (147) are formed integrally and can be arranged in one direction (e.g., perpendicular to each other).

The center of the second coupling portion (147) is the same as the center of the first coupling portion (146), and the length of the second coupling portion (147) can be formed shorter than the length of the first coupling portion (146). The second coupling portion (147) can be supported by being coupled or connected to the Y-axis end of the support frame (140).

The second joint (147) is positioned to face the side cover (1193) of the machine room (119) in the Y-axis direction. A second joint hole (1471) is formed to penetrate the second joint (147) in the Y-axis direction.

The second coupling hole (1471) of the second coupling portion (147) is positioned between the first coupling hole (1461) located in the first coupling portion (146) and the second coupling hole (1471) located in the first coupling portion (146), but may be positioned eccentrically to one side from the center of the second coupling portion (147).

A connecting member such as a screw can be connected to the side cover (1193) of the machine room (119) by passing through the second connecting hole (1471). Through this, the support frame (140) can be connected to the machine room (119) by the second connecting portion (147).

Here, the coupling between the support frame (140) and the fourth panel (104), the coupling between the support frame (140) and one of the first panels (1031), the coupling between the support frame (140) and the other of the first panels (1032), and/or the coupling between the support frame (140) and the side cover (1193) of the machine room (119) may be performed by means of an adhesive, in addition to a coupling member such as a screw.

The first plate extension (1372) and/or the second plate extension (1373) may be arranged in one direction (e.g., vertically) relative to each other, and a free space may be formed therebetween.

In order to prevent heat from leaking from the above-mentioned free space, a side insulation reinforcement part (136) may be further provided on the first and second surfaces of the fourth block part (127). The side insulation reinforcement part (136) is formed to extend in the X-axis direction. The side insulation reinforcement part (136) may have a rectangular cross-sectional shape.

The support frame (140) may be composed of a first support frame (141) and a second support frame (142). The first support frame (141) may be arranged spaced apart from the fourth block portion (127) at a preset first interval.

According to this, the first support frame (141) is spaced apart from one end of the fourth panel (104) by a first gap, thereby minimizing heat transfer and heat leakage between the machine room (119) and the second storage room (106).

The second support frame (142) can be placed at a preset second interval from the protrusion (1351) of the fourth panel (104).

The first part (144) of the second support frame (142) may be positioned lower than the first part (144) of the first support frame (141). The second support frame (142) may be connected to the insulation reinforcement part (135).

The second penetration portion (1292) may be positioned some distance (e.g., forward) from the first penetration portion (1291) in the insulation reinforcement portion (135). The second support frame (142) may be positioned between the first penetration portion (1291) and the second penetration portion (1292).

Through this, the second support frame (142) can be spaced apart from one end of the fourth panel (104) by a second interval to avoid interference with a penetrating component penetrating the fourth panel (104).

The first connecting portion (146) of the first support frame (141) and the first connecting portion (146) of the second support frame (142) can be arranged on the same plane.

The first connecting portion (146) of the second support frame (142) is positioned higher than the first portion (144) of the second support frame (142). The second support frame (142) may include a plurality of connecting portions (143) to overcome the height difference between the first portion (144) and the first connecting portion (146).

The connecting portion (143) extends in the Z-axis direction between the first connecting portion (146) and the first portion (144). The connecting portion (143) may be composed of a first connecting portion (1431) and a second connecting portion (1432).

The first connecting portion (1431) is configured to connect one end of the first portion (144) and the first connecting portion (146). The second connecting portion (1432) is configured to connect the right end of the first portion (144) and the first connecting portion (146).

The connecting portion (143) may be configured to include a first connecting portion (1431) extending in the Z-axis direction from the first portion (144) of the second support frame (142), and a second connecting portion (1432) extending in the Z-axis direction from the second portion (145) of the second support frame (142). The second connecting portion (1432) may be formed to protrude in the Y-axis direction from the first and second ends of the first connecting portion (1431).

Through this, the first connecting portion (146) of the first support frame (141) and the first connecting portion (146) of the second support frame (142) can be positioned on the same plane or spaced apart from each other in the X-axis direction and the Y-axis direction. The ends of one (1031) of the first panels and the other (1032) of the first panels can be connected to the first connecting portion (146) of the first support frame (141) and the first connecting portion (146) of the second support frame (142) on the same plane, respectively.

Referring to FIG. 23b, a suction pipe heat exchanger receiving portion (148) in which a suction pipe heat exchanger is received may be formed inside the fourth block portion (127). The suction pipe heat exchanger is placed between the compressor (120) and the evaporator (114). The suction pipe heat exchanger may be composed of a plurality of straight tubes and a plurality of curved tubes.

The straight tube may be formed to extend in the X-axis direction of the fourth block portion (127). A plurality of straight tubes may be arranged to be spaced apart in the Y-axis direction of the fourth block portion (127). The curved tube may be formed with a preset curvature, such as a semicircle.

A curved tube is formed by connecting a plurality of straight tubes arranged in a direction that is adjacent to or intersecting with one another in the Y-axis direction (e.g., perpendicular to each other).

The suction tube heat exchanger receiving portion (148) is formed to correspond to the shape of the suction tube heat exchanger. For example, the suction tube heat exchanger receiving portion (148) may be composed of a straight tube receiving portion (1481) formed to correspond to a straight tube, and a curved tube receiving portion (1482) formed to correspond to a curved tube.

An internal take-out portion (1483) that is connected to the end of the suction pipe heat exchanger receiving portion (148) may be provided inside the second block portion (128) of the fourth panel (104). The internal take-out portion (1483) is configured to receive a first suction pipe heat exchanger extension portion that is connected to the evaporator (114). The internal take-out portion (1483) extends in the Z-axis direction inside the second block portion (128).

The high-temperature outlet (1483) can be opened in one direction to connect the suction heat exchanger and the evaporator (114). An end of the high-temperature outlet (1483) is blocked in one direction on one side of the second block portion (128) and can be connected to communicate with the suction heat exchanger receiving portion (148). Through this, the suction heat exchanger can be connected to the evaporator (114) through the high-temperature outlet (1483).

An external outlet (1484) that is connected to the end of the suction pipe heat exchanger receiving portion (148) may be provided inside the second block portion (128) of the fourth panel (104). The external outlet (1484) is configured to receive a second suction pipe heat exchanger extension that is connected to the compressor (120).

The external withdrawal part (1484) extends in the Z-axis direction inside the second block part (128). The external withdrawal part (1484) is positioned spaced apart from the internal withdrawal part (1483) in the Y-axis direction inside the second block part (128). The external withdrawal part (1484) is positioned lower than the internal withdrawal part (1483).

The external outlet (1484) may be opened in one direction (e.g., downward) so that the second suction pipe heat exchanger extension is connected to a compressor (120) accommodated outside of the second storage room (106), for example, inside the machine room (119). A portion of the external outlet (1484) may be blocked and may be connected in communication with the suction pipe heat exchanger receiving portion (148). Through this, the suction pipe heat exchanger may be connected to the compressor (120) via the external outlet (1484). The refrigerant may move from the evaporator (114) to the compressor (120) via the suction pipe heat exchanger.

Fig. 18a shows a front plate (149) arranged on one side of the fourth panel (104) in Fig. 10. Fig. 18b is a side view showing a front plate (149) arranged on one side of the fourth panel (104) in Fig. 18a.

FIG. 19 is a cross-sectional view taken along line XIX-XIX in FIG. 18a, and is a conceptual diagram showing a front plate (149) bonded to one surface of the fourth panel (104).

The front plate (149) is formed to extend in the Z-axis direction and the Y-axis direction from one surface of the fourth block portion (127). The front plate (149) is formed in a plate shape in which the Y-axis length is longer than the Z-axis width.

The front plate (149) may be formed to be equal to or longer than the Y-axis length of the fourth block portion (127). In this embodiment, the front plate (149) is shown to be formed longer than the Y-axis length of the fourth block portion (127).

The two ends of the front plate (149) can be respectively joined to one side of one of the first panels (1031) and the other side of the first panel (1032).

A coupling portion may be provided at an end of the front plate (149). The coupling portion may include a first coupling portion (1491) extending in the Y-axis direction and the Z-axis direction from the first end of the front plate (149), and a second coupling portion (1492) extending in the Y-axis direction and the Z-axis direction from the second end of the front plate (149).

The connecting portion may be formed in a plate shape in which the Y-axis length is longer than or equal to the Z-axis width. The Z-axis width of the connecting portion may be formed smaller than or equal to the Z-axis width of the front plate (149). In the present embodiment, the Y-axis length of the connecting portion is formed longer than the Z-axis width. The Z-axis width of the connecting portion is shown to be formed smaller than the Z-axis width of the front plate (149).

A joining hole (1493) is formed to penetrate the joint in the X-axis direction. Through this, a joining member such as a screw can be joined to one of the joining part and the first panel (1031) and/or the other of the joining part and the first panel (1032) through the joining hole (1493). The front plate (149) can be joined to one of the joining part and the first panel (1031) and/or the other of the joining part and the first panel (1032).

The front plate (149) is arranged to be connected to the fourth block portion (127). Through this, the front plate (149) can be tightly connected to the fourth panel (104) by the connecting force of the connecting member penetrating the connecting hole (1493) to the second panel (101). Here, the connecting force of the connecting member is applied in a direction from a part (e.g., the front) of the fourth panel (104) to another part (e.g., the rear).

The two ends of the front plate (149) can be joined to one of the first panels (1031) and/or the other of the first panels (1032) to limit the movement of the fourth panel (104) in one direction (e.g., forward) in the second storage compartment (106).

, the front plate (149) can be positioned higher than the support frame (140). The front plate (149) is positioned adjacent to the first support frame (141). Through this, the front plate (149) can support the fourth panel (104) more firmly together with the support frame (140).

At least one of the first and second ends of the front plate (149) may be provided with a curling portion. The curling portion may include a first curling portion (1494) formed to be rounded at the first end of the front plate (149), and a second curling portion (1495) formed to be rounded at the second end of the front plate (149).

The curling section may be formed so that the hook section protrudes in one direction. The curling section may be inserted and connected to the hook-joining section formed on one side of the fourth block section (127) by the hook section. One side of the curling section may be connected to one side of the fourth block section (127).

The hot line (150) is a component that emits heat. For example, the hot line (150) may be formed in a circular tube shape that extends so that refrigerant flows inside. The hot line (150) is connected to the condenser, and can receive heat generated from the condenser and emit heat. The hot line (150) transmits heat to the connecting surface of the first storage compartment door and/or the second storage compartment door, thereby preventing condensation from occurring due to a temperature difference between the outside and inside of the refrigerator.

The hotline (150) may be provided on one side of the main body (100). The hotline (150) may extend along one side of the partition wall, one side of one of the first panels (1031), one side of the other of the first panels (1032), and/or one side of the fourth panel (104).

A hot line (150) may be installed on one side of the fourth block portion (127) of the fourth panel (104). The hot line (150) may extend in the Y-axis direction to be connected to one side of the front plate (149).

The front plate (149) can be manufactured using a metal material. Through this, the front plate (149) can be connected to the hot line (150) and transmit heat generated from the hot line (150) to the second storage room door.

Figure 20 is a conceptual diagram showing a soft insulation material (151) bonded to the first and second surfaces of the fourth panel (104).

Figure 21 is a conceptual diagram showing a soft insulation material (151) combined with a fourth panel (104).

A soft insulation material (151) may be bonded to at least one side of the fourth panel (104). The soft insulation material (151) may be formed using materials such as carbon felt and porous materials, for example.

A soft insulation material (151) may be placed between the fourth panel (104), which is a non-vacuum insulation material, and the panel, which is a vacuum insulation material. The soft insulation material (151) may include at least one of the first soft insulation material (1511) to the third soft insulation material (1513).

The first soft insulation (1511) can be placed between one of the first panels (1031) and the fourth panel (104). The first soft insulation (1511) can be joined to the first third block portion, the fourth block portion (131), and/or the fourth block portion (127) of the fourth panel (104). The first soft insulation (1511) is in close contact with and faces one of the first panels (1031).

The second soft insulation (1512) can be placed between the other one (1032) of the first panels and the fourth panel (104). The second soft insulation (1512) can be joined to the second third block portion, the other one (132) of the first block portion, and/or the fourth block portion (127) of the fourth panel (104). The second soft insulation (1512) is in close contact with the other one (1032) of the first panels while facing each other.

The third soft insulation (1513) can be placed between the second panel (101) and the fourth panel (104). The third soft insulation (1513) can be joined to the second block portion (128) and/or the fourth block portion (127) of the fourth panel (104). The third soft insulation (1513) is in close contact with the second panel (101) while facing it.

At least one of the first soft insulation material (1511) to the third soft insulation material (1513) can be bonded to the fourth panel (104) by an adhesive or the like.

The soft insulation (151) can seal the fourth panel (104), which is a non-vacuum insulation body, and the main body (100), which is a vacuum insulation body. The soft insulation (151) can prevent cold air from leaking through the gap between the fourth panel (104) and the main body (100).

A third hinge may be arranged on a portion (e.g., the front) of the fourth panel (104). The third hinge is coupled to the main body (100) or the machine room (119) so that a portion of the second storage room door can move relative to the main body (100) or the machine room (119). For example, the third hinge may be installed on the upper portion of the front cover (1191) of the machine room (119).

Therefore, according to the present invention, the third panel (102), the second panel (101), one of the first panels (1031), and the other of the first panels (1032) are composed of a vacuum insulator, and/or the fourth panel (104) forming one side of the main body (100) is composed of an insulating material (125) such as PU foam, which is a non-vacuum insulator.

The fourth panel (104) includes a drain pipe (117) for draining the water, a cycle pipe (118) of the refrigeration cycle device, and a penetration part (129) through which penetration parts such as electric wiring and signal line harnesses penetrate. The penetration part (129) is formed to penetrate the fourth panel (104) in the Z-axis direction.

Accordingly, unlike the prior patents in which the fourth panel (104) was composed of a non-vacuum insulator and/or the fourth panel (104) was applied as a vacuum insulator, a corrugated pipe structure for penetration of a penetrating component and/or a sealing structure for preventing vacuum leakage in the penetration portion (129) of the vacuum insulator are unnecessary, so the structure of the penetration portion (129) is simple, manufacturing is easy, and manufacturing costs can be reduced.

, the fourth panel (104) may be composed of a first cover (124), an insulating material (125), and/or a second cover (126). The first cover (124) and/or the second cover (126) are formed to surround the insulating material (125) and form the exterior of the fourth panel (104). The first cover (124) and/or the second cover (126) are formed by injection molding a plastic resin.

The insulation (125) may be composed of PU foam material. The insulation (125) may be formed by injecting PU foam liquid into the interior of the first cover (124) and the second cover (126) through the foam injection port (1262) formed in the second cover (126) and then foam molding.

A foam cap (1268) (CAP) can be detachably attached to the foam inlet (1262). The foam cap (1268) is configured to have elasticity, such as rubber. A joining groove can be formed along the circumferential direction on the outer surface of the foam cap (1268). Through this, the foam cap (1268) not only prevents leakage of the foam, but also makes it easy to attach and detach the cap.

The fourth panel (104) includes the fourth block portion (127), the second block portion (128), one of the first block portions (131) and/or the other one of the first block portions (132).

The fourth block section (127) can be extended in the X-axis direction and the Y-axis direction to divide the main body (100) in which the storage room is formed and the machine room (119) that accommodates the compressor (120), etc. The fourth block section (127) forms one side of the machine room (119).

The second block portion (128) is formed to protrude in one direction (e.g. upward) from one end of the fourth block portion (127), thereby expanding the insulation area for blocking heat leakage between the second panel (101) and the fourth block portion (127).

One of the first block portions (131) and/or the other of the first block portions (132) may be formed to protrude in one direction from the first end and/or the second end of the fourth block portion (127). Through this, the insulation area for blocking heat leakage between one of the first panels (1031) and the other of the first panels (1032) and the fourth block portion (127) may be expanded.

The insulation reinforcement part (135) is formed to protrude in one direction (e.g. downward) toward the machine room (119) from one side of the fourth block part (127), thereby expanding the insulation area of the fourth panel (104) without affecting the internal volume and reinforcing the insulation performance of the non-vacuum insulation body.

The fourth panel (104) not only blocks heat leakage at the corner portion where at least two panels are connected to each other through the second block portion (128), one of the first block portions (131) and/or the other one of the first block portions (132), but also improves insulation performance without reducing the internal volume through the insulation reinforcement portion (135).

The penetration portion (129) includes a first penetration portion (1291) and/or a second penetration portion (1292). The first penetration portion (1291) is formed to penetrate in the Z-axis direction through the central portion of the second block portion (128), the fourth block portion (127) and/or the insulation reinforcement portion (135) located on one side of the evaporator (114). The first penetration portion (1291) is configured to accommodate and/or surround a drain pipe (117) for draining the defrost water. Accordingly, the fourth panel (104) can block heat exchange between the cold air of the second storage room (106) and the drain pipe (117) through the first penetration portion (1291).

The second penetration portion (1292) is formed to penetrate in the Z-axis direction through the end of the second block portion (128), the fourth block portion (127), and/or the insulation reinforcement portion (135). The second penetration portion (1292) accommodates and/or encloses penetration components such as harnesses for electric wiring and signal lines. Accordingly, the fourth panel (104) can block heat exchange between cold air of the second storage room (106) and electric wiring, etc. through the second penetration portion (1292).

A suction pipe heat exchanger receiving portion (148) is provided inside the fourth block portion (127). The suction pipe heat exchanger receiving portion (148) is formed to correspond to the shape of the suction pipe heat exchanger. An internal outlet portion (1483) and an external outlet portion (1484) connected to at least one of one side and the other side of the suction pipe heat exchanger receiving portion (148) are provided inside the second block portion (128).

The internal take-out portion (1483) is formed to open to the upper portion of the second block portion (128) to accommodate the first suction heat exchanger extension that extends from the suction heat exchanger to the evaporator (114). Accordingly, the internal take-out portion (1483) surrounds the first suction heat exchanger extension that is connected to the evaporator (114), so that the fourth panel (104) can block heat exchange between the cold air of the second storage room (106) and the first suction heat exchanger extension through the internal take-out portion (1483).

The external outlet (1484) is formed to be connected to one side of the second block (128) to accommodate a second suction pipe heat exchanger extension that extends from the other side of the suction pipe heat exchanger to the compressor (120). Accordingly, the external outlet (1484) surrounds the second suction pipe heat exchanger extension that is connected to the compressor (120), so that the fourth panel (104) can block heat exchange between the cold air of the second storage room (106) and the second suction pipe heat exchanger extension through the external outlet (1484).

Accordingly, the penetration portion (129), the internal withdrawal portion (1483) and/or the external withdrawal portion (1484) can be formed as a general penetration hole (1244) or groove structure through which a penetration part can penetrate by applying PU foam material, which is a non-vacuum insulation material, instead of a vacuum insulation material to the fourth panel (104), thereby making it easy to manufacture and greatly contributing to cost reduction.

A second panel (101) composed of a vacuum insulator and an exhaust port (1381) for discharging air in a vacuum space in the first panel (1031, 1032) are formed to protrude toward the second storage room (106). The exhaust port (1381) includes a first exhaust port (1381) protruding from the second panel (101), a second exhaust port (1381) protruding from one of the first panels (1031), and/or a third exhaust port (1381) protruding from the other of the first panels (1032).

The fourth panel (104) includes exhaust port receiving portions (1391, 1392, 1393). The exhaust port receiving portions (1391, 1392, 1393) are formed concavely on one side of the fourth panel (104) to accommodate the exhaust port (1381). For example, the exhaust port receiving portions (1391, 1392, 1393) include at least one of the first exhaust port receiving portion (1391) to the third exhaust port receiving portion (1393).

The first exhaust port receiving portion (1391) may be formed concavely in one direction on one side of the fourth block portion (127) to accommodate the first exhaust port (1381). The second exhaust port receiving portion (1392) may be formed concavely in the fourth block portion (127) to accommodate the second exhaust port (1381). The third exhaust port receiving portion (1393) may be formed concavely in the fourth block portion (127) to accommodate the third exhaust port (1381).

According to this, the exhaust port receiving portion (1391, 1392, 1393) not only provides a space for receiving the exhaust port (1381) for forming a vacuum in the vacuum insulation body without adopting a corrugated pipe structure and a sealing structure, but also has the advantage of simultaneously performing an insulating function by being formed in a form that surrounds the exhaust port (1381) inside the non-vacuum insulation body.

, the fourth panel (104) forms a foam injection port (1262) on the bottom surface, and not only provides a hole for injecting PU foam without adopting a corrugated pipe structure and a sealing structure, but is also easy to manufacture.

In addition, since a support frame (140) is coupled to the bottom surface of the fourth panel (104), it is easy to assemble the fourth panel (104), which is a non-vacuum insulation body, with one of the first panels (1031) of the main body (100), which is a vacuum insulation body, and the other one of the first panels (1032), and it is also possible to support the load applied to the fourth panel (104) and the fourth panel (104) with a simple structure without adopting a corrugated pipe structure and a sealed penetration structure.
