[0014] A penetration portion is formed in the above block so as to penetrate in one direction. A penetration component can be arranged in the penetration portion. The penetration portion accommodates a penetration component that penetrates from the storage room to the machine room or vice versa. The penetration portion includes a first penetration portion that accommodates a drain pipe through which the defrost water generated in the evaporator is drained. The penetration portion includes a second penetration portion that accommodates electric wiring or signal lines.

[0015] The first penetration portion is formed to penetrate one direction in a part or the center of the block. A recess portion is formed toward the first penetration portion at the periphery of the block, or the recess portion is formed to be inclined. The second penetration portion may be arranged to be spaced apart from the first penetration portion, or may be arranged to be spaced apart from the first penetration portion at one end of the block.

[0016] An exhaust port for forming a vacuum space inside the vacuum insulation body is accommodated in an exhaust port receiving portion. The exhaust port receiving portion may be formed on at least one surface of the block.

[0017] An evaporator for evaporating refrigerant to cool the air in the storage room is provided in the storage room. The machine room accommodates a compressor for compressing the refrigerant and / or a condenser for condensing the refrigerant. The through-hole component includes a suction pipe heat exchanger. The suction pipe heat exchanger is accommodated inside the panel. The suction pipe heat exchanger is configured to exchange heat by connecting a suction pipe connected between the evaporator and the compressor and a capillary tube for expanding and delivering refrigerant condensed in the condenser to the evaporator. The main body is connected to the suction pipe heat exchanger and / or includes one or more or a plurality of lead-out portions protruding from one surface of the third panel. The main body is connected to any one of the plurality of lead-out portions and / or includes an external lead-out portion extending from the storage room toward the machine room. The panel includes a cycle pipe receiving portion. The cycle pipe receiving portion is formed on one surface of the block. The cycle pipe receiving portion accommodates the plurality of lead-out portions and the external lead-out portion. The block extends toward the outside of the storage room. The above block is configured to cover a portion of the above panel or a portion of the above vacuum panel.

[0018] The insulator or refrigerator of the present invention may include an insulating reinforcement member. The insulating reinforcement member may include a portion formed to protrude from the block. The insulating reinforcement member may be formed to protrude from a portion of the block toward the machine room. The first penetration portion and the second penetration portion may be spaced apart from each other and / or may be formed to penetrate the block and the insulating reinforcement member.

[0019] A joining groove is formed on one surface of the above insulating reinforcement. The block can be joined to and supported by a portion of the vacuum panel through the joining groove.

[0020] A sloped portion may be formed slanted on one side of the above block.

[0021] An evaporator is provided in the storage room. A return duct is formed on one side of the inclined portion at a predetermined interval from the inclined portion. The return duct can form a path for air circulating from the storage room to the evaporator.

[0022] According to an embodiment of the present invention, the following effects can be achieved.

[0023] First, the body forming the exterior of the refrigerator is composed of vacuum insulation, while the panel dividing the 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 and second plates. The non-vacuum insulation is formed by filling polyurethane foam between the first and second covers.

[0024] Through this, a general penetration structure can be applied to a part of the fourth panel, which is a non-vacuum insulation body, so that the corrugated pipe structure and the 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.

[0025] Therefore, it is easy to manufacture due to its simple structure, 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 cold air leakage and / or perform insulation function with a simple structure by wrapping the penetration part.

[0026] For example, if the penetration portion is formed to simply penetrate the panel in one direction (e.g., up and down), penetration components such as drainage pipes for draining water, cycle pipes of a refrigeration cycle device, and harnesses for electrical wiring and signal lines are surrounded by the penetration portion, so that insulation can be achieved between the penetration portion and the storage chamber 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.

[0027] , an exhaust port receiving portion is formed on at least one surface of the panel so that the exhaust port for vacuum exhaust of the vacuum insulation panel is surrounded and received by the non-vacuum insulation panel. Through this, the exhaust port receiving portion is formed to be sunken into the general groove shape of the panel, so that the simple structure makes it easy to manufacture and reduces manufacturing costs.

[0028] Second, the panel can be formed in three dimensions, including a vacuum panel as a vacuum insulator, a block as a non-vacuum insulator, a first block, and / or an insulating reinforcement member. The vacuum panel is configured to partition the storage room and the 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 insulating reinforcement member can be formed to protrude from one surface of the vacuum panel.

[0029] The panel not only blocks heat leakage by increasing the thickness of the insulation material by protruding toward the inner side of the block at the corner portion where at least two panels are connected to each other through the block and the first block, but also extends the heat transfer path length and / or improves the insulation performance by increasing the thickness of the insulation material by protruding toward the outer side of the block without reducing the inner volume of the block through the insulation reinforcement portion.

[0030] Third, a penetration is formed so that the 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 direction through a part or the center of the block and / or insulation reinforcement.

[0031] 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.

[0032] By forming the water drain pipe 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.

[0033] 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 seal between the fourth panel and the main body easy, but it can also prevent the leakage of cold air.

[0034] Fifth, the non-vacuum insulation reinforcing member can be formed as a single protrusion integral with one side of the block. The insulation reinforcing member has a joining groove that joins with the vacuum panel, so that the non-vacuum insulation can be joined by assembling the vacuum insulation member. This eliminates the need for a separate support frame for joining the panels, and / or improves the panel assemblyability.

[0035] Sixth, a sloped portion may be formed on a portion of the block, which is a non-vacuum insulating material. This sloped portion can minimize the volume of the block protruding toward the interior of the chamber, thereby maximizing the interior volume. Furthermore, the sloped portion can maintain smooth flow in the return path of the second storage chamber.

[0036] 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 is the seal between the panel and the main body easy, but it can also prevent cold air leakage.

The first block (149) can be formed and joined to correspond to the shape of the first portion (e.g., the inclined portion (133)) and / or the second portion (e.g., the vertical surface) formed on one surface of the block (127). One end of the first block (149) is arranged adjacent to one end of one of the first panels (1031) and / or the other of the first panels (1032).

[0226] The Z-axis height of the first block (149) is smaller than the X-axis length of the first block (149). The Z-axis height of the first block (149) may be formed differently from the Y-axis thickness of the first block (149). The Z-axis height of the first block (149) may be formed to be smaller than or equal to the height of the block (127).

At least two of the first panels (1031) and the other of the first panels (1032) and the first block (149) may be arranged to overlap each other in the Y-axis direction. Through this, one of the first panels (1031) and / or the other of the first panels (1032), which is a vacuum insulator, and the first block (149), which is a non-vacuum insulator, can double-block heat leakage.

[0229] The first exhaust port receiving portion (140) is formed concavely on one surface of the block (127). The first exhaust port receiving portion (140) is formed in a rectangular shape having a size capable of accommodating the first exhaust port (136).

[0234] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 10 described above, duplicate descriptions will be omitted.

[0235] Figure 13 is a conceptual diagram showing a soft insulation material bonded between one side of a block (127) and a second panel (101).

[0236] Figure 14 is a conceptual diagram showing a soft insulation material combined with a block (127).

[0237] A soft insulation material may be bonded to at least one surface of the block (127). The soft insulation material may be formed using materials such as carbon felt and / or porous materials, for example.

[0238] 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 a block (127) which is a non-vacuum insulation body and a panel which is a vacuum insulation body.

[0239] 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 one of the first panels (1031).

[0240] 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 placed in close contact with another one of the first panels (1032).

[0241] 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.

[0242] 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 or other adhesive means.

[0243] The block (127), which is a non-vacuum insulator, and the main body (100), which is a vacuum insulator, can be tightly attached to each other by a soft insulator. The soft insulator can prevent cold air from leaking through the gap between the block (127) and the main body (100).

[0244] However, the soft insulation may also be placed between the surfaces where the block (127) or the insulating reinforcement (148)'s joining groove (1481) 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).

[0245] Since other configurations are the same or similar to the embodiments of FIGS. 1 to 12 described above, duplicate descriptions will be omitted.

[0246] Accordingly, 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).

[0247] Through this, since a general penetration structure can be applied to a part of the fourth panel (104), which is a non-vacuum insulator, 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 part (130) formed in the fourth panel (104).

[0248] Therefore, the structure is simple, making it easy to manufacture and greatly contributing 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.

[0249] 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 of electric wiring and signal lines are surrounded by the penetration portion (130), so that insulation can be achieved between the penetration components and the storage room 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.

[0250] An exhaust port receiving portion is formed on at least one surface of the fourth panel (104) so ​​that the 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. Accordingly, the exhaust port receiving portion is formed to be recessed into the general groove shape of the fourth panel (104), thereby facilitating production with a simple structure and reducing manufacturing costs.

[0251] In addition, the fourth panel (104) may be formed three-dimensionally including a vacuum panel (125) which is a vacuum insulator, a block (127) which is a non-vacuum insulator, a first block (149) and / or an insulation reinforcement member (148). The vacuum panel (125) is configured 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).

[0252] 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 through the block (127) and / or the first block (149), thereby not only preventing heat leakage, but also extending the heat movement path length and / or improving the insulation performance by increasing the thickness of the insulation (1273) by protruding toward the outer side without reducing the inner volume of the unit through the insulation reinforcement (148).

[0253] Furthermore, a penetration portion (130) is formed so that a drain pipe (1194) through which the water is drained passes through the central portion of the fourth panel (104). The penetration portion (130) of the water is formed to pass through a part or central portion of the block (127) and / or the insulation reinforcement portion (148) in the Z-axis direction.

[0254] The recess (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.

[0255] By forming the water drain pipe (1194) to penetrate the non-vacuum insulating block (127) and / or the insulation reinforcement (148), the length of the heat transfer path increases, thereby minimizing heat leakage through the water drain pipe (1194).

[0256] 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.

[0257] 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 or the like for separately joining the fourth panel (104) is unnecessary, and / or the assembling ability of the fourth panel (104) can be improved.

[0258] In addition, a sloped portion (133) may be formed on a portion of the block (127), which is a non-vacuum insulating body. Through this, the sloped portion (133) can minimize the volume of the block (127) protruding toward the inside of the high chamber, thereby maximizing the internal volume. The sloped portion (133) can smoothly maintain the flow of the return path of the second storage chamber (106).

[0259] Moreover, 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.
