Heat insulator

Abstract

Disclosed is a refrigerator. The refrigerator includes 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 partitions the storage chamber and the machine chamber. The first panel and the second panel are formed of a vacuum heat insulator, and the fourth panel is formed of a non-vacuum heat insulator. Accordingly, even when the fourth panel does not separately have a corrugated pipe structure and a sealing penetrating 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 heat insulator, so as to penetrate in the Z-axis direction.

Description

[Technical Field]

[0001] The present disclosure relates to an insulator. The present disclosure relates to a refrigerator equipped with a heat insulator.[Background Art]

[0002] Korean Patent No. 10-1960320 (published on July 15, 2019, hereinafter referred to as "Patent Document 1") discloses a refrigerator including a connecting pipe in a corrugated tube configuration in the vacuum space portion between an inner case and an outer case. As disclosed 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 portion. The connecting pipe is formed from a metal sheet, and the side wall of the connecting pipe has a bellows-type corrugated structure. Accordingly, the connecting pipe not only forms a passage through which the pipe passes through the vacuum space portion, but also maintains strength to maintain the airtightness of the vacuum space portion by being elastically deformable, and can withstand the vacuum pressure of the vacuum space portion. Since the connecting pipe of Patent Document 1 penetrates the vacuum heat insulator, sealing is required to prevent vacuum leakage. Manufacturing such a sealing-requiring penetrating structure requires a complex assembly process and requires hermetic connections such as welding, which reduces manufacturability.[Disclosure][Technical Problem]

[0029] According to embodiments of the present disclosure, the following effects can be achieved.

[0030] First, the main body, which forms the exterior of the refrigerator, is formed of the vacuum heat insulator, while the fourth panel, which partitions the main body and the machine chamber, is formed of non-vacuum heat insulator. The vacuum heat insulator forms a vacuum space portion with a certain distance between the first and second plates. The non-vacuum heat insulator is formed by filling polyurethane foam between the first and second covers.

[0031] Through this configuration, since the application of a general penetrating structure to the fourth panel, which is the non-vacuum heat insulator, is possible, the corrugated pipe structure and sealing penetrating structure of the prior patent are unnecessary, and a penetrating component can penetrate from the storage chamber formed inside the main body to the machine chamber disposed on one side of the main body through the penetration portion formed in the fourth panel.

[0032] Therefore, it is easy to manufacture due to its simple structure, and can greatly contribute to reducing manufacturing costs. The penetration portion of the fourth panel, which is the non-vacuum heat insulator, can efficiently prevent cold air leakage and perform insulation function with a simple structure by surrounding the penetrating component.

[0033] For example, when the penetration portion is simply formed to penetrate the fourth panel in the Z-axis direction, penetrating components such as a drain pipe for draining the defrost water, a cycle pipe of a refrigeration cycle device, and a harness for electrical wiring and signal lines are surrounded by the penetration portion, so that insulation can be achieved between the penetrating components and the storage chamber without a separate corrugated pipe structure, and since the fourth panel is the non-vacuum heat insulator, a separate sealing penetrating structure is unnecessary.

[0034] First, the exhaust port for vacuum exhaust of the vacuum heat insulator panel may be surrounded by and accommodated on one side of the fourth panel, which is the non-vacuum heat insulator. The exhaust port receiving portion is formed on the third, first, and / or second surfaces of the fourth panel. This allows the exhaust port receiving portion to be recessed into the general groove shape of the fourth panel, facilitating simple manufacturing and reducing manufacturing costs.

[0035] Second, the fourth panel includes the first block portion 131, the third block portion 132, the fourth block portion, and / or the insulating reinforcement portion. The first block portion 131 is configured to partition the storage chamber and the machine chamber of the main body. The second block portion 128 may be formed to protrude in one direction from the first block portion 131. The third block portion 132 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 131. In addition, the insulating reinforcement portion may be formed to protrude in the other direction from the other surface of the first block portion 131.

[0036] Through this configuration, the fourth panel can improve insulation performance by increasing the thickness or height of a specific portion, that is, the third surface, the first surface, the second surface and / or the third surface.

[0037] 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 128, the third block portion 132, and / or the fourth block portion, but also improves insulation performance without reducing the internal volume through the insulating reinforcement portion.

[0038] Third, the support frame is coupled to the bottom surface of the fourth panel. The first coupling portion and the second coupling portion are respectively provided at both ends 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 chamber. 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 chamber 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 the non-vacuum heat insulator, and the side panel of the main body, which is the vacuum heat insulator, but also can support the fourth panel and the load applied to the fourth panel with a simple structure without adopting the corrugated pipe structure and the sealing penetrating structure.

[0039] In addition, since both ends of the support frame are coupled to the first panel and the second panel through the first coupling portion, the fourth panel can be brought into close contact with the first panel and the second panel.

[0040] Fourth, the support frame may be formed of a metal material. A plurality of support frames may be provided to support the load of the main body. At least two support frames may be disposed spaced apart from at least one of a first end and a second end of the fourth panel. This minimizes leakage of cold air from the second storage chamber through the support frames from the first and second ends of the fourth panel.

[0041] Fifth, since the soft insulating layer is provided between the fourth panel, which is the non-vacuum heat insulator, and the main body, which is a vacuum heat insulator, not only is close contact between the fourth panel and the main body easy, but cold air leakage can be also be prevented.

[0042] Sixth, the penetration portion is formed so that the drain pipe through which the defrost water is discharged penetrates the central portion of the fourth panel. The defrost water penetration portion is formed to penetrate the central portion of the second block portion 128, the first block portion 131, and / or the insulating reinforcement portion in the Z-axis direction.

[0043] The recess portion is formed to be inclined at a preset angle toward the upper portion of the defrost water penetration portion in the second block portion 128, so that the defrost water can drain smoothly.

[0044] By forming the defrost water drain pipe to penetrate the second block portion 128, the first block portion 131, and / or the insulating reinforcement portion, the length of the heat transfer path is increased, thereby minimizing heat leakage through the defrost water drain pipe.

[0045] Seventh, the front plate can be coupled to one surface of the fourth panel. By coupling both ends of the front plate to the side panels, the fourth panel can be brought into close contact with the third panel of the main body.[Description of Drawings]

One 131 of the first block portion 131s and the other 132 of the first block portion 131s may extend in one direction from the end of the fourth block portion 127. The height in the Z-axis direction of one 131 of the first block portion 131s and the other 132 of the first block portion 131s may be formed to be smaller than the length in the X-axis direction of one 131 of the first block portion 131s and the other 132 of the first block portion 131s, and may be formed to be longer than the thickness in the Y-axis direction of one 131 of the first block portion 131s and the other 132 of the first block portion 131s.

[0169] One 131 of the first block portion 131s is disposed to face one 1031 of the first panels in the Y-axis direction. The other 132 of the first block portion 131s is disposed to face the other 1032 of the first panels in the Y-axis direction.

[0170] A door side mounting groove 133 is formed in one 131 of the first block portion 131s and the other 132 of the first block portion 131s. The door side mounting groove 133 is formed to be concave in the Y-axis direction on one surface of one 131 of the first block portion 131s and the other 132 of the first block portion 131s so that the side surface of the second storage chamber door is accommodated on one surface of one 131 of the first block portion 131s and the other 132 of the first block portion 131s when the second storage chamber door is closed.

[0171] One surface 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 end to the second end of the door side mounting groove 133.

[0172] Through this configuration, when the second storage chamber door is closed, the interference between one 131 of the first block portion 131s and the other 132 of the first block portion 131s and a portion (for example, the left and right surfaces) of the second storage chamber door can be reduced, thereby minimizing resistance. A portion (for example, the left and right surface portions) of the second storage chamber door is formed of a rubber material capable of elastic deformation, so that sealing may be formed between the second storage chamber door and the main body 100.

[0173] In addition, a portion of the second storage chamber door and the insulating layers 125 of one 131 of the first block portion 131s and the other 132 of the first block portion 131s are disposed to overlap each other, thereby preventing heat from leaking through the gap between the second storage chamber door and the main body 100.

[0271] The 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 surface of the front plate 149.

[0272] The front plate 149 may be manufactured using a metal material. Through this configuration, 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 chamber door.

[0273] FIG. 20 is a conceptual diagram illustrating a state where a soft insulating layer 151 is coupled to the first and second surfaces of the fourth panel 104.

[0274] FIG. 21 is a conceptual diagram illustrating a state where the soft insulating layer 151 is coupled to the fourth panel 104.

[0275] The soft insulating layer 151 may be coupled to at least one surface of the fourth panel 104. The soft insulating layer 151 may be formed using materials such as carbon felt and porous materials, for example.

[0276] The soft insulating layer 151 may be disposed between the fourth panel 104, which is a non-vacuum heat insulator, and the panel, which is a vacuum heat insulator. The soft insulating layer 151 may include at least one of the first soft insulating layer 1511 to the third soft insulating layer 1513.

[0277] The first soft insulating layer 1511 may be disposed between one 1031 of the first panels and the fourth panel 104. The first soft insulating layer 1511 may be coupled to the first block portion 131, second block portion 128, the third block portion 132, and / or the fourth block portion 127 of the fourth panel 104. The first soft insulating layer 1511 faces and is in close contact with one 1031 of the first panels.

[0278] The second soft insulating layer 1512 may be disposed between the other 1032 of the first panels and the fourth panel 104. The second soft insulating layer 1512 may be coupled to the other of the first block portion 131 and the third block portion 132, and / or the fourth block portion 127 of the fourth panel 104.The second soft insulating layer 1512 faces and is in close contact with the other 132 of the first panels.

[0279] The third soft insulating layer 1513 may be disposed between the second panel 101 and the fourth panel 104. The third soft insulating layer 1513 may be coupled to the second block portion 128 and / or the fourth block portion 127 of the fourth panel 104. The third soft insulating layer 1513 faces and is in close contact with the second panel 101.

[0280] At least one of the first soft insulating layer 1511 to the third soft insulating layer 1513 may be coupled to the fourth panel 104 by an adhesive means such as an adhesive.

[0281] The soft insulating layer 151 may be in close contact with the fourth panel 104, which is a non-vacuum heat insulator, and the main body 100, which is a vacuum heat insulator. The soft insulating layer 151 may prevent cold air from leaking through the gap between the fourth panel 104 and the main body 100.

[0282] A third hinge may be disposed on a portion (for example, the front) of the fourth panel 104. The third hinge is coupled to the main body 100 or the machine chamber 119 so that a portion of the second storage chamber door can move relative to the main body 100 or the machine chamber 119. For example, the third hinge may be installed on the upper portion of the front cover 1191 of the machine chamber 119.

[0283] Accordingly, according to the present disclosure, the third panel 102, the second panel 101, one 1031 of the first panels, and the other 1032 of the first panels are formed of a vacuum heat insulator, and / or the fourth panel 104 forming one surface of the main body 100 is formed of an insulating layer 125 such as PU foam, which is a non-vacuum heat insulator.

[0284] The fourth panel 104 includes a drain pipe 117 for draining the defrost water, a cycle pipe 118 of the refrigeration cycle device, and a penetration portion 129 through which a penetrating component such as a harness of electrical wiring and signal line passes. The penetration portion 129 is formed to penetrate the fourth panel 104 in the Z-axis direction.

[0285] Through this configuration, unlike the prior patents in which the fourth panel 104 is formed of a non-vacuum heat insulator and / or the fourth panel 104 is applied as a vacuum heat insulator, a corrugated pipe structure for penetration of the penetrating component and / or a sealing structure for preventing vacuum leakage in the penetration portion 129 of the vacuum heat insulator is unnecessary, so the structure of the penetration portion 129 is simple, manufacturing is easy, and manufacturing costs can be reduced.

[0286] The fourth panel 104 may include a first cover 124, an insulating layer 125, and / or a second cover 126. The first cover 124 and / or the second cover 126 are formed to surround the insulating layer 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.

[0287] The insulating layer 125 may be formed of PU foam material. The insulating layer 125 may be formed by injecting a PU foaming liquid into the interior of the first cover 124 and the second cover 126 through the foaming liquid injection port 1262 formed in the second cover 126 and then foaming.

[0288] A foaming liquid cap 1268 (CAP) may be detachably coupled to the foaming liquid injection port 1262. The foaming liquid cap 1268 is configured to have elasticity, such as from a rubber material. A coupling groove may be formed along the circumferential direction of the outer peripheral surface of the foaming liquid cap 1268. Through this configuration, the foaming liquid cap 1268 not only prevents leakage of the foaming liquid, but also facilitates attachment and detachment of the cap.

[0289] The fourth panel 104 includes the fourth block portion 127, the second block portion 128, one 131 of the first block portion 131s and / or the other one of the first block portion 131s 132.

[0290] The fourth block portion 127 may extend in the X-axis direction and the Y-axis direction to partition the main body 100 in which the storage chamber is formed and the machine chamber 119 that accommodates the compressor 120 or the like. The fourth block portion 127 forms one surface of the machine chamber 119.

[0291] The second block portion 128 is formed to protrude in one direction (for example, 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.

[0292] One 131 of the first block portion 131s and / or the other 132 of the first block portion 131s 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 configuration, the insulation area for blocking heat leakage between one 1031 of the first panels and the other 1032 of the first panels and the fourth block portion 127 may be expanded.

[0293] The insulating reinforcement portion 135 is formed to protrude in one direction (for example downward) toward the machine chamber 119 from one surface of the fourth block portion 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 heat insulator.

[0294] 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 131 of the first block portion 131s and / or the other 132 of the first block portion 131s, but also improves insulation performance without reducing the internal volume through the insulating reinforcement portion 135.

[0295] The penetration portion 129 includes the first penetration portion 1291 and / or the second penetration portion 1292. The first penetration portion 1291 is formed to penetrate in the Z-axis direction the central portion of the second block portion 128, the fourth block portion 127, and / or the insulating reinforcement portion 135 positioned on one side of the evaporator 114. The first penetration portion 1291 is configured to accommodate and / or surround the drain pipe 117 for draining the defrost water. Accordingly, the fourth panel 104 may block heat exchange between the cold air of the second storage chamber 106 and the drain pipe 117 through the first penetration portion 1291.

[0296] The second penetration portion 1292 is formed to penetrate the end of the second block portion 128, the fourth block portion 127, and / or the insulating reinforcement portion 135 in the Z-axis direction. The second penetration portion 1292 accommodates and / or surrounds the penetrating components such as harnesses for electrical wiring and signal lines. Accordingly, the fourth panel 104 may block heat exchange between cold air of the second storage chamber 106 and electrical wiring, or the like, through the second penetration portion 1292.

[0297] The suction line heat exchanger accommodating portion 148 is provided inside the fourth block portion 127. The suction line heat exchanger accommodating portion 148 is formed to correspond to the shape of the suction line heat exchanger. The inner outlet portion 1483 and the outer outlet portion 1484 connected to at least one of one side and the other side of the suction line heat exchanger accommodating portion 148 are provided inside the second block portion 128.

[0298] The inner outlet portion 1483 is formed to open to the upper portion of the second block portion 128 to accommodate the first suction line heat exchanger extension extending from the suction line heat exchanger to the evaporator 114. Accordingly, the inner outlet portion 1483 surrounds the first suction line heat exchanger extension connected to the evaporator 114, so that the fourth panel 104 may block heat exchange between the cold air of the second storage chamber 106 and the first suction line heat exchanger extension through the inner outlet portion 1483.

[0299] The outer outlet portion 1484 is formed to communicate with one side of the second block 128 to accommodate the second suction line heat exchanger extension that extends from the other side of the suction line heat exchanger to the compressor 120. Accordingly, the outer outlet portion 1484 surrounds the second suction line heat exchanger extension that is connected to the compressor 120, so that the fourth panel 104 may block heat exchange between the cold air of the second storage chamber 106 and the second suction line heat exchanger extension through the outer outlet portion 1484.

[0300] Accordingly, the penetration portion 129, the inner outlet portion 1483 and / or the outer outlet portion 1484 may be formed as a general through hole 1244 or groove structure through which a penetrating component can penetrate by applying PU foam material, which is a non-vacuum heat insulator, instead of a vacuum heat insulator to the fourth panel 104, thereby making it easy to manufacture and greatly contributing to cost reduction.

[0301] The second panel 101 formed of a vacuum heat insulator and the exhaust port 1381 for exhausting air from the vacuum space portion in the first panels 1031 and 1032 are formed to protrude toward the second storage chamber 106. The exhaust port 1381 includes the first exhaust port 1381 protruding from the second panel 101, the second exhaust port 1381 protruding from one 1031 of the first panels, and / or the third exhaust port 1381 protruding from the other 1032 of the first panels.

[0302] The fourth panel 104 includes the exhaust port receiving portions 1391, 1392, and 1393. The exhaust port receiving portions 1391, 1392, and 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, and 1393 include at least one of the first exhaust port receiving portion 1391 to the third exhaust port receiving portion 1393.

[0303] The first exhaust port receiving portion 1391 may be formed concavely in one direction on one surface 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.

[0304] According to this, the exhaust port receiving portions 1391, 1392, and 1393 not only provides the accommodating space of the exhaust port 1381 for forming a vacuum in the vacuum heat insulator without adopting a corrugated pipe structure and a sealing structure, but also has the advantage of being able to perform an insulating function at the same time by being formed in a form that surrounds the exhaust port 1381 inside the non-vacuum heat insulator.

[0305] The fourth panel 104 forms a foaming liquid injection port 1262 on the bottom surface, and not only provides a hole for injecting the PU foaming liquid without adopting a corrugated pipe structure and a sealing structure, but is also easy to manufacture.

[0306] In addition, since the 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 heat insulator, with one 1031 of the first panels of the main body 100 and the other 1032 of the first panels, which are vacuum heat insulators, and it is possible to support the fourth panel 104 and the load applied to the fourth panel 104 with a simple structure without adopting the corrugated pipe structure and the sealing penetrating structure.
