Abstract

A refrigerator is disclosed. The refrigerator includes a fourth panel for sectioning off a storage chamber formed inside a main body from a machine room disposed at one side of the main body. The main body is formed of a vacuum insulator. The fourth panel is formed from a combination of a vacuum panel of the vacuum insulator and a block of a non-vacuum insulator. Therefore, even if the fourth panel does not have a separate bellows pipe structure and a sealable pass-through structure, a pass-through component passing therethrough from the storage chamber to the machine room can pass through a pass-through part passing through the inside the block of the non-vacuum insulator in the Z-axis direction.

Description

Korean Patent No. 10-1960320 (publication date July 15, 2019, hereinafter referred to as “Patent Document 1”) discloses a refrigerator having a connecting pipe having 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 a communication port of the inner case and a communication port of the outer case in the vacuum space. The connecting pipe is formed of a metal sheet, and the side walls of the connecting pipe have a corrugated structure of the bellows type. 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 airtight joints such as welding must be performed, 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 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 and/or improves manufacturability and reduces manufacturing costs.

The fourth objective is to provide a refrigerator having a structure that can maintain insulation performance and/or minimize heat leakage at the corners of the panel.

The insulating reinforcement member may be formed to protrude from a portion of the block toward the machine room. The first penetration member and the second penetration member may be spaced apart from each other and/or formed to penetrate the block and the insulating reinforcement member.

A joining groove is formed on one side of the above insulation reinforcement member. The block can be joined to and supported by a part of the vacuum panel through the joining groove.

A sloped portion may be formed slanted on one side of the above block.

An evaporator is provided in the above storage room. A return duct is formed on one side of the inclined portion at an angle set apart from the inclined portion. The return duct can form a path for air circulated from the storage room to the evaporator.

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, and the panel dividing the main body and the machine room is composed of a combination of vacuum insulation and 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 a general penetration structure can be applied to a part of the fourth panel, which is a non-vacuum insulating body, the corrugated pipe structure and sealed penetration structure of the prior patent are unnecessary, and/or a penetration part can penetrate from a storage room formed inside the body to a machine room arranged on one side of the body through the penetration formed in the fourth panel.

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

For example, if the penetration portion is formed to simply penetrate the panel in one direction (e.g., upward and downward), penetration components such as a drain pipe for draining water, a cycle pipe of a 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 component and the storage room without a separate corrugated pipe structure, and since a part of the panel where the penetration portion is formed is a non-vacuum insulator, a separate sealed penetration structure is unnecessary.

, an exhaust port for vacuum exhaust of a vacuum insulation panel is surrounded and accommodated by a non-vacuum insulation panel, and an exhaust port accommodation portion is formed on at least one surface of the panel. Accordingly, the exhaust port accommodation portion is formed to be sunken into a general groove shape of the panel, so that the manufacturing is easy with a simple structure and the manufacturing cost can be reduced.

Second, the panel can be formed in three dimensions including a vacuum panel as a vacuum insulation body, a block as a non-vacuum insulation body, a first block, and/or an insulation reinforcement member. The vacuum panel is formed to partition a storage room and a machine room of the main body. The block can be joined to the vacuum panel. The first block is formed to protrude from one side of the vacuum panel. In addition, the insulation reinforcement member can be formed to protrude from one surface of the vacuum panel.

The panel increases the thickness of the insulation material by protruding toward the inner side at the corner portion where at least two panels are connected to each other through the block and the first block, thereby preventing heat leakage. In addition, the thickness of the insulation material is increased by protruding toward the outer side without reducing the inner volume of the panel through the insulation reinforcement portion, thereby extending the heat movement path length and/or improving the insulation performance.

Third, a penetration is formed so that a drain pipe through which the water is discharged passes through the center of the fourth panel. The penetration is formed so as to penetrate one way through a part or the center of the block and/or the insulation reinforcement.

The recessed portion is formed at a preset angle from the end of the block toward one side of the water penetration portion, so that the water can drain smoothly.

Since the water drain pipe is formed to penetrate the non-vacuum insulating block and/or the insulation reinforcement, the length of the heat transfer path is increased, thereby minimizing heat leakage through the water drain pipe.

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

Fifth, the insulation reinforcement member, which is a non-vacuum insulation body, can be formed by protruding integrally with one side of the block. The insulation reinforcement member has a joining groove that is joined to the vacuum panel, so that the non-vacuum insulation body can be joined by assembling the vacuum insulation body. According to this, a support frame, etc. for separately joining the panels is unnecessary, and/or the assembly of the panels can be improved.

Sixth, a slope may be formed on a portion of the block, which is a non-vacuum insulating body. Through this, the slope can minimize the volume of the block protruding toward the inside of the high-temperature chamber, thereby maximizing the internal volume of the high-temperature chamber. The slope can smoothly maintain the flow of the return path of the second storage chamber.

Seventh, since a soft insulation material is provided between a part of the panel, which is a non-vacuum insulation body, and the main body, which is a vacuum insulation body, not only does it facilitate close contact between the panel and the main body, it also prevents leakage of cold air.

The vacuum panel (125) forms a part of the fourth panel (104). The block (127) forms another part of the fourth panel (104).

The vacuum panel (125) is composed of a vacuum insulator. The vacuum panel (125) may be composed of a first plate (1251), a second plate (1252), and/or a support. The first plate (1251) is arranged toward the second storage room (106). The second plate (1252) is arranged toward the outside of the main body (100). In this embodiment, the second plate (1252) of the vacuum panel (125) is arranged toward the machine room (122). The support is configured to maintain a vacuum space (1253) formed between the first plate (1251) and the second plate (1252).

The vacuum panel (125) has a preset thickness and extends in the X-axis direction and the Y-axis direction, and/or is formed in a rectangular shape. The length of the vacuum panel (125) in the Y-axis direction corresponds to the distance between one of the first panels (1031) and the other of the first panels (1032).

The first end and/or the second end of the vacuum panel (125) may be coupled to one of the first panels (1031) and/or the other of the first panels (1032).

The X-axis length of the vacuum panel (125) is shorter than the X-axis length of one of the first panels (1031) and/or the other of the first panels (1032). The vacuum panel (125) is arranged so as to be connectable to the door. One end of the vacuum panel (125) is arranged to be spaced apart from the second panel (101) by a preset interval.

The opening (126) between the vacuum panel (125) and the second panel (101) is formed to be covered by the block (127) described below. The opening (126) can be arranged to overlap in the Z-axis direction of the evaporator (116). The opening (126) extends in the X-axis direction and the Y-axis direction. The Y-axis length of the opening (126) is longer than the X-axis width of the opening (126). The X-axis width of the opening (126) can be formed to correspond to the X-axis width of the evaporator (116).

The block (127) is composed of a non-vacuum insulation material. The block (127) is composed of polyurethane foam (hereinafter, abbreviated as PU foam).

The block (127) includes a first cover (1271), a second cover (1272) and/or insulation (1273).

The first cover (1271) and/or the second cover (1272) form the outer shape of the fourth panel (104). The first cover (1271) and/or the second cover (1272) may be composed of a plastic material. The first cover (1271) and/or the second cover (1272) may be formed by injection molding.

An insulating material (1273) such as PU foam can be foamed and molded between the first cover (1271) and the second cover (1272). Polyurethane foam can be injected into the internal space of the first cover (1271) and the second cover (1272) through a foaming injection port (not shown) and then foamed.

Through this, the block (127) is foam-molded using a polyurethane foam material, so that the first penetration portion (131) and/or the second penetration portion (132) do not destroy the insulation of the block (127) without the need to maintain a vacuum state, and a sealed penetration structure is unnecessary and/or can be easily formed inside the block (127).

The first cover (1271) is configured to cover at least a portion of the insulation material (1273). The second cover (1272) is configured to cover one side of the insulation material (1273).

The first cover (1271) and/or the second cover (1272) may be connected to each other by an adhesive, etc. However, in addition to the adhesive, etc., the first cover (1271) and/or the second cover (1272) may be connected by various connecting means, such as a screw connection by a screw or a snap fit connection by a hook.

A block (127) is placed on one side of the second panel (101). The block (127) is formed to cover an opening (126) between the second panel (101) and the vacuum panel (125). A portion of the block (127) may be placed to overlap the vacuum panel (125).

A joining groove may be formed on one side of the block (127). A part of the vacuum panel (125) may be accommodated in the joining groove. The block (127) may be joined to the vacuum panel (125) in the joining groove. Through this, the block (127) may be joined by assembly with the vacuum panel (125) and at least one of the first panels (1031) and the other one of the first panels (1032).

The block (127) can be formed to protrude in one direction from the vacuum panel (125). The block (127) extends along the Y-axis direction of the vacuum panel (125).

A block (127) is placed between the vacuum panel (125) and the second panel (101). The block (127) is configured to connect the fourth panel (104) and/or the second panel (101). The block (127) is placed to cover the opening (126) so as to block heat leaking through the opening (126).

One side of the block (127) is positioned so as to face the second panel (101) in the X-axis direction and overlap with it. Through this, the block (127) and the second panel (101) can double-block heat leakage through the overlapping structure of the non-vacuum insulation material (1273) and the vacuum insulation.

A mounting portion (1281, 1282), a recess portion (129), and/or a drainage groove (1293) are provided on one surface of the block (127).

The second second storage joint (113), which is positioned at the corner where the other one of the first panels (1032) and the second panel (101) are connected, is positioned and supported by the second anchoring portion (1282).

The penetration portion (130) is formed to penetrate the block (127) in the Z-axis direction. The penetration portion (130) accommodates a penetration component so that the penetration component can penetrate the block (127). The penetration component may include a drain pipe (1194) and/or wiring such as an electric wire.

The penetration portion (130) may be composed of a first penetration portion (131) and/or a second penetration portion (132). The first penetration portion (131) accommodates a drain pipe (1194) of the sump (119). The first penetration portion (131) may be formed to correspond to the shape of the drain pipe (1194). In this embodiment, the first penetration portion (131) is shown as being formed in a circular tube shape.

The recessed portion (129) is arranged between the first anchoring portion (1281) and/or the second anchoring portion (1282). The recessed portion (129) is formed to be inclined at an angle corresponding to the bottom wall of the sump (119). The recessed portion (129) is connected to the bottom wall and/or can support the sump (119). Through this, the recessed portion (129) guides the flow of the defrost water together with the bottom wall of the sump (119) to the drain (1193), thereby facilitating the drainage of the defrost water.

A drainage groove (1293) is formed in the center of the recessed portion (129). The recessed portion (129) includes a first recessed portion (1291) and/or a second recessed portion (1292).

The drainage groove (1293) is formed to be sunken in one direction at the bottom of the recessed portion (129). The first penetration portion (131) is formed to penetrate the drainage groove (1293) in the Z-axis direction of the block (127). The first penetration portion (131) may also be formed to be able to penetrate the insulation reinforcement portion (148) described later.

Through this, the drain pipe (1194) can be accommodated in the first penetration portion (131) and/or can pass through the block (127) through the first penetration portion (131) or be connected to a separate connecting pipe. The first penetration portion (131) can wrap around the drain pipe (1194) to minimize heat leakage through the drain pipe (1194).

The second penetration portion (132) accommodates a pipe having wires, etc. embedded therein. The pipe may be formed into a corrugated pipe structure that is adjustable in length or easy to bend.

The second penetration portion (132) can be formed in the first fixing portion (1281) or the second fixing portion (1282). In the present embodiment, the second penetration portion (132) is shown as being formed to penetrate one side of the second fixing portion (1282) in the Z-axis direction. The second penetration portion (132) has a circular cross-sectional shape smaller than the square area of the second fixing portion (1282). The cross-sectional shape of the second penetration portion (132) is not limited to a circle and can be formed in various shapes such as a polygon.

The second penetration portion (132) can also be formed to be able to penetrate the insulation reinforcement portion (148) described later.

Through this, the pipe can be accommodated in the second penetration portion (132) and/or can pass through the block (127) through the second penetration portion (132). The second penetration portion (132) can wrap around the pipe, thereby minimizing heat leakage through the pipe.

A block (127) may be provided with an inclined portion (133). The inclined portion (133) is arranged toward the second storage room (106). The inclined portion (133) is formed to be inclined at a preset angle with respect to a vertical line. The inclined portion (133) is formed to be inclined downward so that the thickness of the block (127) in the X-axis direction increases from one end of the block (127) to the other end.

Through this, the slope (133) can maintain the insulation performance of the block (127) and/or minimize the internal volume.

A return duct (121) may be provided on one side of the inclined portion (133). The return duct (121) forms an intake path on one side to suck in air from the second storage chamber (106). The return duct (121) may be formed at a preset interval from the inclined portion (133) and/or at an angle to the inclined portion (133).

One end of the return duct (121) may be connected to communicate with a space in which an evaporator (116) is accommodated, and/or the other end of the return duct (121) may be connected to communicate with a second storage room (106).

The other end of the return duct (121) is positioned at a preset interval from the first plate (1251) of the vacuum panel (125). An intake port is formed between the other end of the return duct (121) and the first plate (1251) of the vacuum panel (125).

Through this, air from the second storage room (106) can be sucked into the return duct (121) through the intake port and returned to the evaporator (116).

The exhaust port is formed to protrude from the first plate (1251) of the vacuum insulator. The exhaust port is configured to discharge at least a portion of the air in the vacuum space (1253) to the outside in order to maintain the vacuum space (1253) of the vacuum insulator in a vacuum state.

The second panel (101), one of the first panels (1031), the other of the first panels (1032) and/or the vacuum panel (125) may be independently manufactured from vacuum insulation. Accordingly, one exhaust port may be provided for each panel.

For example, the exhaust port may include a first exhaust port (136), a second exhaust port (137), a third exhaust port (138), and/or a fourth exhaust port (139). The first exhaust port (136) may be formed to protrude in one direction from a portion of the first plate (134) of the second panel (101). The second exhaust port (137) may be formed to protrude in the first direction from the first plate (134) of one of the first panels (1031).

The exhaust port receiving portions (140, 141, 142, 143) may include the first exhaust port receiving portion (140) to the fourth exhaust port receiving portion (143) to receive exhaust ports protruding from each panel.

The first exhaust port receiving portion (140) is formed to be sunken in one direction (e.g., forward) on one side of the block (127) facing the second panel (101) to receive the first exhaust port (136) protruding from the second panel (101). The first exhaust port receiving portion (140) is arranged on one side of the block (127). The first exhaust port receiving portion (140) is arranged so as not to overlap with the first through-hole portion (131) and/or the second through-hole portion (132).

For example, the first exhaust port receiving portion (140) may be spaced apart from one side of the block (127) in a first direction by a first interval from one side of the block (127) facing one of the first panels (1031). The first exhaust port receiving portion (140) may be spaced apart from one side of the block (127) in a second direction by a second interval from one side of the block (127) facing the other side of the first panels (1032). The first interval and the second interval may be different from each other. In the present embodiment, the first interval is larger than the second interval.

The first exhaust port receiving portion (140) can be placed between the first through-hole portion (131) and the second through-hole portion (132).

Through this, the first exhaust port receiving portion (140) can receive and wrap the first exhaust port (136) of the second panel (101), thereby blocking heat leakage through the first exhaust port (136) of the second panel (101). The first exhaust port receiving portion (140) can avoid interference with the first through-port (131) and/or the second through-port (132) and/or block heat transfer with the drain pipe (1194) or the pipe. The first exhaust port receiving portion (140) can also avoid interference with the outlet (146) of the suction pipe heat exchanger (145) to be described later and/or block heat exchange with the outlet (146) of the suction pipe heat exchanger (145).

The second exhaust port receiving portion (141) (see FIG. 19) may be formed to be recessed in the first direction in the first block (1491) described later to accommodate the second exhaust port (137) protruding from one of the first panels (1031).

The fourth exhaust port receiving portion (143) is arranged to be spaced apart in one direction (e.g., forward) from the first through-hole portion (131) in the block (127).

The suction pipe heat exchanger (145) may be accommodated inside the second panel (101). A plurality of lead-out portions (146) formed to protrude from the second panel (101) may be provided. A first lead-out portion (1461) of the plurality of lead-out portions (146) is configured to connect a capillary tube and a suction pipe heat exchanger (145). A second lead-out portion (1462) of the plurality of lead-out portions (146) is configured to connect an evaporator (116) and a suction pipe heat exchanger (145). A third lead-out portion (1463) of the plurality of lead-out portions (146) is configured to connect a compressor (123) and a suction pipe heat exchanger (145).

An external withdrawal unit (147) may be connected to the third withdrawal unit (1463). The external withdrawal unit (147) may extend from the second storage room (106) to the machine room (122). At this time, the external withdrawal unit (147) may penetrate the block (127).

The block (127) may include a cycle pipe storage section (144).

The cycle pipe receiving portion (144) is formed to be sunken in one direction (e.g., forward) on one side of the block (127) to accommodate a plurality of withdrawal portions (146) protruding from one side of the second panel (101).

The cycle pipe receiving portion (144) may be spaced apart from one side of the block (127) in the first direction by a third spacing from one side of the block (127) facing one of the first panels (1031) and/or spaced apart from one side of the block (127) in the second direction by a fourth spacing from one side of the block (127) facing the other side of the first panels (1032). The third spacing and the fourth spacing may be different from each other. In the present embodiment, the fourth spacing is larger than the third spacing.

The third withdrawal part (1463) can be placed between the first withdrawal part (1461) and the second withdrawal part (1462).

A high-external penetration hole is provided in the cycle pipe receiving portion (144) so that an external withdrawal portion (147) can pass through it. The high-external penetration hole is formed to penetrate in one direction from the cycle pipe receiving portion (144) toward the machine room (122). Through this, the high-external withdrawal portion (147) can extend from the cycle pipe receiving portion (144) through the high-external penetration hole and pass through the block (127) to the machine room (122) and/or be connected to the compressor (123).

An insulation reinforcement member (148) is further provided on one side of the block (127). The insulation reinforcement member (148) extends from the block (127) to the machine room (122). Through this, the insulation reinforcement member (148) can minimize heat leakage through the gap between the ends of the block (127) without affecting the internal volume.

The insulation reinforcement part (148) is configured to reinforce insulation performance by expanding the insulation area from the block (127) to the machine room (122).

The insulation reinforcement member (148) is formed to protrude in one direction from one side of the block (127). The Z-axis thickness of the insulation reinforcement member (148) may be smaller than or equal to the Z-axis thickness of the block (127).

The insulation reinforcement part (148) extends in the Y-axis direction along one side of the block (127).

The insulation reinforcement member (148) may be formed to extend in the X-axis direction of the block (127). The block (127) and/or the insulation reinforcement member (148) may be arranged to overlap the vacuum panel (125) in the Z-axis direction. One side of the insulation reinforcement member (148) and one side of the block (127) form the same plane and may be connected to the second panel (101).

The length of the insulation reinforcement member (148) extending in one direction (e.g., forward) based on one side of the vacuum panel (125) may be less than or equal to the length of one end (e.g., front end) of the block (127). One side of the insulation reinforcement member (148) may be located behind one end (e.g., front end) of the block (127).

A joining groove (1481) may be formed on one surface of the insulation reinforcement member (148). The joining groove (1481) is positioned to face one surface of the vacuum panel (125). The joining groove (1481) is formed concavely on one surface of the insulation reinforcement member (148). The joining groove (1481) extends along the Y-axis direction on one surface of the insulation reinforcement member (148). The joining groove (1481) may be formed in a shape corresponding to a portion of the vacuum panel (125) so as to accommodate a portion of the vacuum panel (125). Through this, the vacuum panel (125) may be joined to one of the first panels (1031) and/or the other of the first panels (1032). The insulation reinforcement member (148) may be joined to the vacuum panel (125) through the joining groove (1481). Through this, the block (127) can be joined between the second panel (101) and the vacuum panel (125).

The first penetration portion (131) and/or the second penetration portion (132) may be formed to penetrate the block (127) and/or the insulation reinforcement portion (148) in the Z-axis direction.

The insulation reinforcement member (148) is further provided with a protrusion (1482). The protrusion (1482) is formed to protrude further from one side of the insulation reinforcement member (148). The protrusion length of the protrusion (1482) of the insulation reinforcement member (148) corresponds to the thickness of the second panel (101) in the X-axis direction. Accordingly, the second panel (101) can be supported by being secured to the protrusion (1482) of the insulation reinforcement member (148).

The protrusion (1482) extends in the Z-axis direction. One side of the protrusion (1482) can form the same plane as one side of the insulation reinforcement (148).

A soft insulation may be bonded to at least one surface of the block (127). The soft insulation may be formed using materials such as, for example, carbon felt and/or porous materials.

The soft insulation may include a first soft insulation (153), a second soft insulation (154), and/or a third soft insulation (155). The soft insulation may be placed between the non-vacuum insulation block (127) and the vacuum insulation panel.

The first soft insulation (153) can be placed between one of the first panels (1031) and the block (127). The first soft insulation (153) can be joined to the first block (1491). The first soft insulation (153) is in close contact with and faces one of the first panels (1031).

The second soft insulation (154) can be placed between another one of the first panels (1032) and the block (127). The second soft insulation (154) can be joined to the second first block (1492). The second soft insulation (154) is in close contact with and faces another one of the first panels (1032).

The third soft insulation (155) can be placed between the second panel (101) and one side of the block (127). The third soft insulation (155) can be bonded to one side of the block (127). The third soft insulation (155) is in close contact with the second panel (101) while facing it.

The first soft insulation material (153), the second soft insulation material (154), and/or the third soft insulation material (155) can be bonded to three sides of the block (127) by an adhesive, etc.

The block (127), which is a non-vacuum insulation body, and the main body (100), which is a vacuum insulation body, can be tightly attached to each other by a soft insulation material. The soft insulation material can prevent cold air from leaking through the gap between the block (127) and the main body (100).

However, the soft insulation may also be placed between the surface where the joining groove (1481) of the block (127) or the insulation reinforcement (148) and the vacuum panel (125) are connected to each other. Through this, the block (127), which is a non-vacuum insulation body, and the vacuum panel (125), which is a vacuum insulation body, can be in close contact with each other. The soft insulation can prevent cold air from leaking through the gap between the block (127) and the vacuum panel (125).

Since other configurations are the same or similar to the embodiments of FIGS. 1 to 12 described above, duplicate descriptions will be omitted.

Therefore, according to the present invention, the main body (100) forming the exterior of the refrigerator is composed of a vacuum insulator, and the fourth panel (104) dividing the main body (100) and the machine room (122) is composed of a combination of a vacuum insulator and a non-vacuum insulator. The vacuum insulator forms a vacuum space (1341, 1253) with a certain gap between the first plate (134, 1251) and the second plate (135, 1252). The non-vacuum insulator is formed by filling polyurethane foam between the first cover (1271) and the second cover (1272).

Through this, since a general penetration structure can be applied to a part of the fourth panel (104), which is a non-vacuum insulating body, the corrugated pipe structure and/or the sealed penetration structure of the prior patent is unnecessary, and/or a penetration part can penetrate from a storage room formed inside the main body (100) to a machine room (122) arranged on one side of the main body (100) through the penetration portion (130) formed in the fourth panel (104).

Therefore, since the structure is simple, it is easy to manufacture and can greatly contribute to reducing manufacturing costs. The penetration part (130) of the fourth panel (104), which is a non-vacuum insulation body, can efficiently prevent leakage of cold air and/or perform insulation function with a simple structure by wrapping the penetration part.

For example, if the penetration portion (130) is simply formed to penetrate the fourth panel (104) in the Z-axis direction, penetration components such as a drain pipe (1194) for draining the water, a cycle pipe of a refrigeration cycle device, and a harness for electric wiring and signal lines are surrounded by the penetration portion (130), so that insulation can be formed between the penetration components and the storage chamber without a separate corrugated pipe structure, and since a part of the fourth panel (104) where the penetration portion (130) is formed is a non-vacuum insulator, a separate sealed penetration structure is unnecessary.

An exhaust port receiving portion is formed on at least one surface of the fourth panel (104) so that an exhaust port for vacuum exhaust of the vacuum insulation panel is surrounded and received by the fourth panel (104), which is a non-vacuum insulation body. Accordingly, the exhaust port receiving portion is formed to be sunken in the general groove shape of the fourth panel (104), so that it is easy to manufacture with a simple structure and the manufacturing cost can be reduced.

In addition, the fourth panel (104) may be formed three-dimensionally including a vacuum panel (125) which is a vacuum insulation body, a block (127) which is a non-vacuum insulation body, a first block (149), and/or an insulation reinforcement member (148). The vacuum panel (125) is formed to partition the storage room and the machine room (122) of the main body (100). The block (127) may be coupled to the vacuum panel (125). The first block (149) is formed to protrude from the vacuum panel (125). In addition, the insulation reinforcement member (148) may be formed to protrude in one direction from one surface of the vacuum panel (125).

In addition, the fourth panel (104) increases the thickness of the insulation (1273) by protruding toward the inner side at the corner portion where at least two panels are connected to each other via the block (127) and/or the first block (149), thereby preventing heat leakage, and extends the heat movement path length and/or improves insulation performance by increasing the thickness of the insulation (1273) by protruding toward the outer side without reducing the inner volume via the insulation reinforcement portion (148).

Furthermore, a penetration portion (130) is formed so that a drain pipe (1194) through which the water is discharged passes through the center of the fourth panel (104). The penetration portion (130) of the water is formed so as to pass through a part or the center of the block (127) and/or the insulation reinforcement portion (148) in the Z-axis direction.

The recessed portion (129) is formed to be inclined at a preset angle toward one side of the water penetration portion (130) at the end of the block (127), so that the water can be drained smoothly.

Since the water drain pipe (1194) is formed to penetrate the non-vacuum insulating block (127) and/or the insulation reinforcement part (148), the length of the heat transfer path increases, thereby minimizing heat leakage through the water drain pipe (1194).

In addition, since a soft insulation material is provided between the block (127) of the fourth panel (104), which is a non-vacuum insulation body, and the main body (100), which is a vacuum insulation body, not only is the sealing between the fourth panel (104) and the main body (100) easy, but also leakage of cold air can be prevented.

The insulation reinforcement member (148), which is a non-vacuum insulation body, can be formed by protruding integrally with one side of the block (127). The insulation reinforcement member (148) has a joining groove (1481) that is joined to the vacuum panel (125), so that the non-vacuum insulation body can be joined by assembling the vacuum insulation body. According to this, a support frame, etc. for separately joining the fourth panel (104) is unnecessary, and/or the assembling ability of the fourth panel (104) can be improved.

In addition, an inclined portion (133) may be formed on a part of the block (127), which is a non-vacuum insulating body. Through this, the inclined portion (133) can minimize the volume of the block (127) protruding toward the inside of the high chamber, thereby maximizing the internal volume. The inclined portion (133) can smoothly maintain the flow of the return path of the second storage room (106).

Furthermore, since a soft insulation material is provided between a part of the fourth panel (104), which is a non-vacuum insulation body, and the main body (100), which is a vacuum insulation body, not only is the sealing between the fourth panel (104) and the main body (100) easy, but also leakage of cold air can be prevented.
