Abstract
Description
Technical Field
[0001] This invention relates to a heat insulation material. Background Technology
[0002] First, there is the applicant's authorized patent 10-0343719 (Patent Document 1). According to that authorized patent, the method involves: manufacturing a vacuum adiabatic panel; embedding the vacuum adiabatic panel into the wall of a refrigerator; and finishing the exterior of the vacuum adiabatic panel using a separately molded polystyrene foam. According to this method, foaming is unnecessary, and improved insulation performance can be achieved. However, this method suffers from increased cost and a more complex manufacturing process.
[0003] As another example, there have been attempts to manufacture the entire refrigerator wall as a single vacuum insulation unit. For instance, US Patent Publication US20040226956A1 (Patent Document 2) discloses an insulation structure for a refrigerator that provides insulation in a vacuum state. However, it is difficult to provide a sufficiently vacuum state in the refrigerator wall to achieve a practically usable level of insulation. Specifically, there are problems such as difficulty in isolating heat transfer at the contact points between the outer and inner shells, which have different temperatures; difficulty in maintaining a stable vacuum state; and difficulty in preventing deformation of the shell caused by the negative pressure of the vacuum state.
[0004] Japanese Patent Publication No. 2011-247534 (Patent Document 3) discloses a heat insulation box body that is equipped with multiple vacuum heat insulation panels, thereby simplifying the bonding operation and improving productivity.
[0005] Patent document 3 discloses an insulated box body, which includes an inner box, an outer box, and multiple vacuum insulation panels disposed between them. The insulated box body of the refrigerator, which constitutes multiple wall parts of the refrigerator body, is formed by combining multiple inner box segments that are divided into an inner box as a whole. At the same time, the multiple vacuum insulation panels are formed into shapes that correspond to each inner box segment. Each of these vacuum insulation panels and each inner box segment is disposed in the insulated box body.
[0006] Existing insulation materials suffer from deformation caused by vacuum pressure and deformation caused by the internal shelves and loads of the refrigerator.
[0007] Existing insulation materials have structural strength and insulation performance issues at corners or where multiple insulation materials are joined.

[0087] The heat insulation element 10 of the present invention can be applied to a refrigerator 1. The refrigerator 1 may include: a body 2, providing a cabinet 9 capable of storing items; and a door 3 configured to open and close the body 2. The cabinet 9 is equipped with a cold source for supplying cold air. As an example, the cold source may be an evaporator 7 that evaporates refrigerant to remove heat. The refrigerator may include a compressor 4 that compresses the refrigerant. The refrigerator may include a condenser 5 that condenses the compressed refrigerant. The condenser 5 may be connected to an expander 6 that expands the condensed refrigerant.
[0088] In this invention, the third plate 16 can prevent the wall forming the heat insulation body 10 from deforming, denting, or collapsing towards the interior of the vacuum space 15.
[0089] The wall forming the insulation 10 may include a first plate 11 and a second plate 12. A third plate 16 may be disposed on at least one of the first plate 11 and the second plate 12.
[0090] The third plate 16 can be disposed in the thinner portion of the first plate 11 and the second plate 12. The third plate 16 can also be disposed in the weaker portion of the first plate 11 and the second plate 12.
[0091] The third plate 16 can be disposed on at least one side of the inner and outer sides of the vacuum space portion 15.
[0092] The third plate 16 may be disposed on at least one curved portion of the first plate 11 and the second plate 12. The third plate 16 may be disposed on at least a portion of the periphery of the vacuum space 15 or the first plate 11 and the second plate 12. The third plate 16 may be disposed separately from the heat insulation member covering the periphery of the vacuum space 15 or the first plate 11 and the second plate 12. The third plate 16 may be disposed on at least a portion of the heat insulation member covering the periphery of the vacuum space 15 or the first plate 11 and the second plate 12. The third plate 16 may be configured to extend to the outermost corner rod among a plurality of rods disposed inside the first plate 11 and the second plate 12. The third plate 16 may extend to a portion of at least one curved portion 11b, 12c of the first plate 11 and the second plate 12.
[0093] The third plate 16 may have a thickness thinner than either the first plate 11 or the second plate 12. The third plate 16 may have portions with different thicknesses. The third plate 16 may have portions with variable thickness. The third plate 16 may have longer and more curved portions to accommodate heat conduction paths.
[0094] The third plate 16 may include a grid-shaped portion. The third plate 16 may include a portion that has been cut off on one side.
[0095] The portion of the third plate 16 that overlaps with the support member grid can have a thinner thickness 16b. The portion of the third plate 16 that does not overlap with the support member grid can have a thicker thickness 16a. In the portion where the third plate 16 overlaps with the support member grid, the density of the support member grid can be reduced. The support member grid can be a grid comprising a plurality of rods 20 and support plates 22a, 22b.
[0096] The third plate 16 may be disposed between the support plate of the support assembly and at least one of the first plate 11 and the second plate 12.
[0097] Figure 6 An example is shown where the first plate 11 and the second plate 12 are supported by two rods.
[0098] Reference Figure 6 The third plate 16 can be configured to be inserted inside or outside the first plate 11. The third plate 16 can extend to cover at least a portion of the outermost rod. This prevents damage or deformation caused by sagging of the first plate 11.
[0099] The third plate 16 may not extend to the portion where the first plate 11 and the second plate 12 are joined or sealed to each other. The third plate 16 may not extend to the side frame or the second part 11b of the first plate 11. The third plate 16 may have a surface that connects at least a portion of the first part 11a of the first plate 11.
[0100] A reinforcing member 40 may be provided on one side of the second plate 12. The reinforcing member 40 may be disposed on one side of the insulation 10 and / or have a curved portion to facilitate strength enhancement. Since the reinforcing member 40 may be disposed at a corner on one side of the second plate 12, it may also be referred to as a corner frame. When at least two insulations 10 are joined together, the reinforcing member 40 may be disposed between the second plate 12 of the first insulation 10 and the second plate 12 of the second insulation 10. The strength of the second plate 12 itself can be enhanced by the reinforcing member 40, and the strength between the first insulation and the second insulation 10 can be enhanced. As an example, the reinforcing member 40 may be disposed in the third portion of the second plate 12. The reinforcing member 40 may be inserted into a portion that is further curved from the third portion.
[0101] The second plate 12 may include a first portion 12a forming a vacuum insulation portion and a second portion 12b extending further from the first portion 12a.
[0102] The second plate 12 may include a third portion 12c that is bent from the second portion 12b. One side of the third portion 12c may be further bent. Thus, the second plate 12 can form a structure that is bent twice, thereby using the shape itself to enhance strength.
[0103] At least two insulation elements 10 can be joined together between the second plate 12 of the structure that is bent twice from one side. Thus, strength can be increased at the joint of the at least two insulation elements 10.
[0104] Figure 7 An example is shown where the third plate 16 is configured not to cover the outermost corner rod 20 and the rod 20 adjacent to the outermost corner rod 20. The third plate 16 may be configured to extend between the second and third rods 20 from the outermost side.
[0105] A block 30 may be provided on one side of the heat insulation body 10. The block 30 may include a non-vacuum heat insulation portion. The block 30 may also include a portion that covers or is combined with the non-vacuum heat insulation portion.
[0106] The third plate 16 can be separate from or not overlap with the block 30 along the length of the insulation 10. This reduces heat transfer from the third plate 16 to the block 30.
[0107] The third plate 16 may not extend to the edge of the first plate 11. This reduces heat transfer from the third plate 16 through the first plate 11 to the second plate 12.
[0108] Optionally, the heat insulation body 10 of the present invention may include a support member for maintaining the vacuum space 15. The support member may include a rod 20 and support plates 22a, 22b. The rod 20 may extend along the thickness direction of the vacuum space 15. The support plates 22a, 22b may be connected to at least one of the first plate 11 and the second plate 12. The support plates 22a, 22b may connect a plurality of rods 20 to each other.
[0109] Optionally, the heat insulation body 10 of the present invention may include a radiation-resistant sheet 23 that reduces the amount of heat transfer generated by radiation. The radiation-resistant sheet 23 may be formed parallel to the longitudinal direction of one of the first plate 11 and the second plate 12 in the vacuum space portion 15. A plurality of radiation-resistant sheets 23 may be provided.
[0110] Figure 8 An example is shown where the third plate 16 extends to one side of the first plate 11 via the outermost corner rod 20. As an example, when the third plate 16 extends to the position where the block 30 is provided and the edge of the first plate 11, deformation may occur in the outermost corner rod 20 due to the third plate 16. In particular, when high-temperature exhaust is used to form the vacuum space 15, deformation of the edge portion may occur due to deformation of the first plate 11.
[0111] That is, the third plate 16 preferably does not extend to the edge of the first plate 11. In this way, the third plate 16 can be separated from the edge of the first plate 11. As a result, deformation or damage can be prevented from the outermost corner bar 20 of the heat insulation body 10 and the bar 20 adjacent to the outermost corner bar 20 or near the edge of the heat insulation body 10.
[0112] Reference Figure 9 The third plate 16 can be formed to include a cut portion 16e that is cut on one side.
[0113] The third plate 16 can be cut open on one side of the insulation 10. The portion of the third plate 16 where the block 30 of the first plate 11 is disposed or the portion where the insulation 10 is joined to each other can be cut open. The cut portion 16e of the third plate 16 can separate the block 30.
[0114] Reference Figure 10 Optionally, the third plate 16 may be provided with grid-shaped ribs 16b, 16c, and 16d.
[0115] Optionally, at least two heat insulation elements 10 may be provided in directions that intersect each other. A block 30 may be easily provided on one side between the heat insulation elements 10 that are connected to each other.
[0116] It may be difficult to install blocks 30 in the portion between at least two insulation bodies 10 (i.e., corner portions). The corner portions where the door meets the body may also include portions for the joining of decorative elements. Thus, the portion between the insulation bodies 10 may have areas that are not easily insulated.
[0117] Therefore, if the third plate 16 is provided with grid-shaped ribs 16b, 16c, and 16d, the amount of heat transferred through the third plate 16 can be reduced by utilizing the space between the ribs 16b, 16c, and 16d. This improves the heat insulation performance of parts that are difficult to insulate (such as the corners of the insulation body 10).
[0118] The third plate 16 can be formed as a plate, or as a grid, or as a combination of a plate-shaped portion and a grid-shaped portion.
[0119] Reference Figure 10 The third plate 16 may include a plate portion 16a and a grid portion.
[0120] The plate-shaped portion may include plate portion 16a. The grid-shaped portion may include grid-shaped ribs 16b, 16c, and 16d.
[0121] The plate portion 16a may be formed as an inner or outer portion disposed between the edge sides of the third plate 16. The plate portion 16a may have a thickness greater than that of the first plate 11. The plate portion 16a may have a thickness less than that of the second plate 12 or have the same thickness as the second plate 12.
[0122] The plate portion 16a may have a specified thickness and area.
[0123] The grid portion may be disposed on at least one side of the plate portion 16a. The grid portion may be connected to the edge of the plate portion 16a. The grid portion may include a first grid 16b and a second grid 16c. The first grid 16b may extend in one direction. The second grid 16c may extend in a direction intersecting the first grid 16b. The grid portion may include a border grid 16d that is configured to form the edge of the third plate 16.
[0124] Figure 10 An example is shown in which a plate portion 16a is formed on the inner or outer portion between the sides of the frame, and square portions 16b, 16c, and 16d are provided on the four sides of the plate portion 16a.
[0125] The grid-shaped ribs are formed by including a first grid, a second grid, and a border grid, thereby utilizing the space between the first grid, the second grid, and the border grid to reduce the amount of heat transferred through the third plate 16. As a result, the heat insulation performance of parts that are not easily insulated (such as the corners of the insulation body 10) can be improved.
[0126] Figure 11 The image shows a third plate 16 comprising grid-shaped ribs 16b, 16c, 16d and plate portion 16a.
[0127] The third plate 16 is disposed on the support member. A block 30 may be disposed overlappingly on the side of the third plate 16 where the grid-shaped ribs 16b, 16c, and 16d are provided. The block 30 may have a portion that does not overlap with or is separate from the plate portion 16a of the third plate 16.
[0128] This structure allows for reinforcement on one side of the insulation 10, where the block 30 is located. The space between the grid ribs 16b, 16c, and 16d can be used to reduce the degradation of insulation performance caused by conduction.
[0129] The grid-shaped ribs 16b, 16c, and 16d can be configured to overlap with the support member. The grid-shaped ribs 16b, 16c, and 16d can also be configured to overlap with the rod 20. Optionally, the grid-shaped ribs 16b, 16c, and 16d can have portions parallel to the extending direction of the support plates 22a and 22b supporting the rod 20. This allows for increased strength in the insulation 10 on which the rod 20 is disposed.
[0130] Optionally, the square ribs 16b, 16c, and 16d may have a wider spacing than the support plates 22a and 22b of the support rod 20. The spacing between the first squares may be wider than the spacing between the support plates 22a and 22b of the support rod 20. The spacing between the second squares may be wider than the spacing between the support plates 22a and 22b of the support rod 20. (Refer to...) Figure 11 The square ribs 16b, 16c, and 16d can be formed with a spacing that is approximately two or three times wider. Therefore, the space between the square ribs 16b, 16c, and 16d can be used to reduce the degradation of thermal insulation performance caused by conduction.
[0131] Optionally, the thickness of the square ribs 16b, 16c, and 16d can be set to be thinner than the thickness of the plate portion 16a, thereby improving the thermal insulation performance on one side of the insulation body 10.
[0132] Figure 12 and Figure 13 An example is shown in which a third plate 16 is provided on the first plate 11, wherein the third plate 16 has portions of different thicknesses.
[0133] Optionally, the third plate 16 may have portions with different thicknesses. The third plate 16 may include a first plate portion 16a and a second plate portion 16a. The first plate portion 16a may be a portion of the third plate 16 configured away from the edge portion of the heat insulation body 10. The second plate portion 16a may be a portion of the third plate 16 configured close to the edge portion of the heat insulation body 10. The second plate portion 16a may be formed from a component separate from the first plate portion 16a. Preferably, the thickness of the portion of the third plate 16 adjacent to the edge of the heat insulation body 10 is formed to be thinner, thereby minimizing the deterioration of the heat insulation performance. The first plate portion 16a may be formed to be thicker than the second plate portion 16a. As an example, the first plate portion 16a may have the same thickness as the first plate 11. The second plate portion 16a may have a thickness that is thicker than the first plate 11 and thinner than the second plate 12. The second plate portion 16a may have a portion overlapping with the block 30. The second plate portion 16a is preferably formed to allow for a longer heat conduction path. The second plate portion 16a may not extend to the edge of the heat insulation 10. The second plate portion 16a may have a portion parallel to the first portion of the first plate 11.
[0134] Optionally, the third plate 16 may have a portion separate from the block 30 disposed on one side of the insulation 10.
[0135] Figure 14 This indicates an improvement in heat transfer due to the reduction or removal of the third plate 16, or due to the structure having square ribs 16b, 16c, 16d.
[0136] When the third plate 16 is reduced in size by approximately 50 mm, a 2.5% improvement in heat transfer can be confirmed. Compared to reducing the third plate 16 by approximately 50 mm, when the third plate 16 is reduced in size by approximately 60 to 90 mm, no significant improvement in heat transfer can be confirmed. Therefore, it is preferable to reduce the third plate 16 by approximately 50 mm.
[0137] Figures 15 to 17An example is shown where heat conduction can be minimized by increasing the pitch between a plurality of rods 20. Support plates 22a and 22b can be formed as a grid structure having portions extending along a first direction and portions extending along a second direction intersecting the first direction. A plurality of rods 20 can be disposed at the intersections of the portions extending along the first direction and the portions extending along the second direction of the support plates 22a and 22b. The plurality of rods 20 can be alternately disposed at the intersections of the portions extending along the first direction and the portions extending along the second direction. That is, the plurality of rods 20 can be disposed at 13 out of a total of 25 intersections. This increases the pitch of the rods 20 in the portion where the third plate 16 is disposed. Compared to a structure where rods 20 are disposed at all 25 intersections, a structure where rods 20 are disposed at 13 out of 25 intersections increases the average pitch from 23 mm to 32 mm. Therefore, referring to… Figure 17 The graph, with 100% coverage, confirms a 7.5% improvement in power consumption. Due to the increased spacing of the multiple rods 20, heat conduction can be minimized without developing additional molds. With 46% coverage of the increased spacing area, a 3.5% improvement in power consumption can be confirmed.
