Description

Technical Field

[0001] This invention relates to heat insulation. Specifically, this invention relates to a refrigerator equipped with heat insulation. Background Technology

[0002] In refrigerators and similar appliances, insulation is used to prevent the internal temperature from rising due to temperature differences between the outside and the inside of the refrigerator. In this case, vacuum insulation is widely used as the insulation, employing vacuum insulation technology that utilizes the phenomenon of reduced thermal conductivity of low-pressure gases. Such vacuum insulation typically has a first plate and a second plate forming a constant space, and is formed by venting gas (e.g., air) from the space between the first plate and the second plate and / or sealing the space.

[0003] The insulation is panel-shaped, and devices such as refrigerators have a structure in which multiple insulations are assembled together. Therefore, each side of the insulation is joined to other insulations. This joining with other insulations is typically achieved by welding the plates that make up the insulation.

[0004] However, when the insulation is fused together, to prevent damage to the sealed vacuum space caused by the fusion, the insulation has an edge portion protruding from the center portion forming the sealed vacuum space. To support the edge portion, a side portion, although thinner than the center portion, forms the sealed vacuum space between the center portion and the edge portion. With this structure, multiple insulation units can be joined together by fusing them together through the edge portions, and by bending the fused portions, a structure such as a refrigerator can be formed without damaging the sealed vacuum space.

[0005] However, the central portion of the insulation has an insulation effect based on a vacuum space, while the edge portion does not have a vacuum space. Therefore, it does not have an insulation effect. In this case, there is a problem that heat exchange between the edge portion and the outside air may cause loss of cold air in devices such as refrigerators.

[0006] On the other hand, as described above, when the sealed space between the first and second plates of the insulation is in a vacuum state, it is susceptible to atmospheric pressure or external forces. Therefore, a technique has been proposed in which a support member, having a support pin formed between the first and second plates to support the sealed vacuum space, is slidably disposed within the sealed space. However, this technique suffers from the problem that atmospheric pressure or external forces concentrate at the support pin or at the locations of the support pin on the first or second plate, thereby causing the support pin or the location of the support pin on each plate to become fragile.

[0007] Furthermore, as mentioned above, in the case of a heat insulation body with side portions, there is a problem that it is difficult to configure the support unit on the side portion using the method of configuring the support unit in the aforementioned sliding manner. If the support unit is not configured on the side portion, there is a problem that the structure of the heat insulation body is easily damaged when a side load is applied. Summary of the Invention

[0008] The problem to be solved

[0009] The object of the present invention is to solve the aforementioned and other problems and to provide a thermal insulation having a support portion that can further improve structural strength by effectively distributing the applied load.

[0010] Another objective of the present invention is to provide a heat insulation body having a support portion that not only disperses the load applied to the center portion of the heat insulation body, but also further improves the structural strength of the side portion by dispersing the side load applied to the side portion formed between the center portion and the edge portion.

[0011] Another object of the present invention is to provide a combined structure of the insulation body that also includes a frame capable of preventing loss of cold air due to the edge of the insulation body without a vacuum space being exposed to air.

[0084] The embodiments disclosed in this specification will now be described in detail with reference to the accompanying drawings.

[0085] Figure 5 This is a cross-sectional view of the structure of a heat insulation body 500 including a central portion 510, a side portion 520 and / or an edge portion 530, according to an embodiment of the present invention.

[0086] First, such as Figure 5 As shown, the heat insulation body 500 of this embodiment can be formed in a bag shape and can be implemented using a first plate 501 and a second plate 502 forming a vacuum region. It may include: a space forming the vacuum region by including a sealed space that forms a vacuum; and an edge portion 530, wherein the first plate and the second plate are joined together as a single plate without including the space forming the vacuum region. The space forming the vacuum region may include a central portion 510 and / or a side portion 520. The side portion may extend from the central portion 510 to the edge portion 530 and / or the side portion may be formed between the central portion 510 and the edge portion 530. Here, as... Figure 5As shown, the central portion 510 and the side portion 520 can be distinguished by the thickness difference of the space forming the vacuum region.

[0087] The side portion 520 is used to effectively distribute the load applied to the side of the insulation 500, i.e., the edge portion 530, and can be formed between the center portion 510 and the edge portion 530. The first plate 501 and the second plate 502 can form arcuate surfaces in a direction approaching each other, and / or bend gently at first. An entry portion (first step) 531 of the side portion 520 can be formed, having a thickness thinner than the thickness of the vacuum space of the center portion 510. The first plate 501 and the second plate 502 can again form arcuate surfaces in a direction approaching each other at the end portion (second step) 532 of the side portion 520, and / or bend gently a second time. An edge portion 530 can be formed where the first plate 501 and the second plate 502 join.

[0088] That is, such as Figure 5 As shown, according to an embodiment of the present invention, in a heat insulation body 500 that forms a vacuum space in the shape of a bag, the first plate 501 and the second plate 502 forming the vacuum space may each have a step gradient including a first step 531 and a second step 532 formed in a direction toward each other. Based on the first step 531 and the second step 532, the space can be divided into three parts: a central portion 510, a side portion 520, and an edge portion 530. That is, based on the first step 531 and the second step 532, the first plate 501 and the second plate 502 may have a shape that gradually approaches each other, i.e., the separation distance between the first plate 501 and the second plate 502 gradually decreases. The first plate 501 and the second plate 502 have the same shape, and therefore can be shared plates.

[0089] As described above, by sealing the edge portion 530 formed at the edge, a sealed space can be formed according to the central portion 510 and / or the side portion 520. A heat-insulating bag-shaped heat insulation body 500 can be formed by making the air pressure in the sealed space lower than the external air pressure (e.g., vacuum).

[0090] On the other hand, as described Figure 5 As shown, the heat insulation body 500 having edge portions 530 can be combined with other heat insulation bodies by means of the joint (e.g., welding) between the edge portions 530. Figure 5As shown, the edge portion 530 is the part where the first plate 501 and the second plate 502 are completely joined into one plate, and therefore it is easy to bend. Thus, the portion corresponding to the edge portion 530 can be bent along the structural outline of the object device (e.g., a refrigerator) to cover the appearance along the structural outline of the object device. That is, a plurality of heat insulation bodies assembled using the edge portion 530 can cover the appearance of the object device.

[0091] Figure 6 This is a top view showing an example of two insulation bodies 500-1 and 500-2 connected to each other by their edges. Figure 6 This is a top view showing the second thermal insulation member 610 and the first thermal insulation member 620 configured to surround a portion (e.g., the inside and the outside) of the curved edge portion 530. Figure 7 It is shown that Figure 6 A perspective view of an example of a second heat insulation member 610 disposed between a first heat insulation body 500-1 and a second heat insulation body 500-2.

[0092] First, refer to Figure 6 The first heat insulator 500-1 and the second heat insulator 500-2 can be joined together by the edge portions 530 of the first heat insulator 500-1 and / or the second heat insulator 500-2 engaging with each other. The engaging edge portions 530 of the first heat insulator 500-1 and the second heat insulator 500-2 can be bent along the structural shape of the object device (e.g., a refrigerator). Therefore, as Figure 6 As shown, a first heat insulation body 500-1 and a second heat insulation body 500-2 can be formed by connecting each other through edge portions 530 that are bent at an angle (e.g., 90 degrees) according to the shape of the corner of the object device.

[0093] On the other hand, the edge portion 530 is part of the heat insulation body 500; therefore, cold air inside the object device insulated from the outside by the heat insulation body 500 may be transferred to the edge portion 530. If the edge portion 530 is exposed to air, the cold air inside the object device insulated by the heat insulation bodies 500-1 and 500-2 may be lost due to heat exchange between the edge portion 530 and the outside air. Therefore, in order to prevent the loss of cold air caused by heat conduction to the edge portion 530, the present invention may provide at least one heat insulation member capable of preventing the edge portion 530 from being exposed to air.

[0094] As an example, the heat insulation member may include a heat insulation member (first heat insulation member 620) for preventing the edge portion 530 from being exposed to air outside the device. Figure 6 As shown, the first heat insulation member 620 may be formed to surround the edge portion 530 that bends along the structural shape of the object device and / or to be formed to be closely attached to the bend of the edge portion 530.

[0095] On the other hand, the first heat-insulating member 620 may be formed to cover the edge portion 530 and / or the side portion 520 of the heat-insulating body 500, to further adhere to the edge portion 530 and / or improve the heat insulation effect. For this purpose, the first heat-insulating member 620 may be provided with a step corresponding to a second step 532 formed on the inner side panels of the first heat-insulating body 500-1 and the second heat-insulating body 500-2 respectively. The first heat-insulating member 620 may be formed to extend from the second step 532 to a region corresponding to a first step 531 formed on the inner side panels of the first heat-insulating body 500-1 and the second heat-insulating body 500-2 respectively. Here, the reference for the inner and outer sides is the object device; the plate in the first and second plates forming the heat-insulating body that corresponds to the inner side of the object device may be named the inner side panel. The plate that corresponds to the outer side of the object device may be named the outer side panel.

[0096] On the other hand, in order to integrate the first thermal insulation member 620, an assembly block 600 may also be included on the inner side of the curved edge portion 530 (based on the object device). The assembly block 600 is configured such that at least one side is in close contact with the curved edge portion 530. The assembly block 600 can be integrated inside the object device. As an example, such as Figure 6 As shown, the assembly block 600 may be a connecting member disposed at the inner center of the edge portion 530 that bends along the corner shape of the device. The assembly block 600 is disposed along the structural outline of the object device, therefore the edge portion 530 may be bent along the outer surface of the assembly block 600 to correspond to the structural shape of the object device.

[0097] In this case, one side of the assembly block 600 may be in close contact with one side of the first heat insulation body 500-1 and / or the connected edge portion 530, and / or the other side of the assembly block 600 adjacent to the first side may be in close contact with one side of the edge portion 530 connected to the second heat insulation body 500-2.

[0098] On the other hand, at least one of the surfaces of the assembly block 600 that is in close contact with the edge portion 530 (hereinafter referred to as the mating surface) may be formed with an insertion groove into which the connecting member can be inserted. A first through hole corresponding to the insertion groove formed on the mating surface of the assembly block 600 may also be formed in a region of the edge portion 530 that is in close contact with the mating surface of the assembly block 600. The first heat-insulating member 620 covering the edge portion 530 may also be formed with a second through hole corresponding to the insertion groove and / or the first through hole. Thus, the connecting member and the assembly block 600 can be joined by the connecting member sequentially passing through the second through hole formed in the first heat-insulating member 620, the first through hole formed in the edge portion 530, and being inserted into the insertion groove formed on the mating surface of the assembly block 600. Thus, the connecting member can be joined to the assembly block 600. The first heat-insulating member 620 and the edge portion 530 can be joined to the assembly block 600 as the connecting member is joined to the assembly block 600. As described above, the first heat insulation body 500-1 and / or the second heat insulation body 500-2, which are engaged by the edge portion 530, can be combined with the assembly block 600, i.e., the target device.

[0099] The assembly block 600 can be formed of metal or high-strength plastic. The connecting member can be a bolt. In this case, the insertion slot can be formed with threads that can engage with the bolt.

[0100] On the other hand, the heat insulation member can be disposed not only outside the device but also inside the device. In this case, the heat insulation member disposed inside the device and preventing heat loss from the edge 530 can be referred to as the second heat insulation member 610 to distinguish it from the first heat insulation member 620.

[0101] like Figure 6 As shown, the second heat insulation member 610 is disposed between the assembly block 600 and the edge portion 530 adjacent to the assembly block 600, and is formed to cover the inner side surface of the curved edge portion 530. As described above, when both the first heat insulation member 620 and the second heat insulation member 610 are provided, the edge portion 530 connecting the first heat insulation body 500-1 and the second heat insulation body 500-2 can be covered by the first heat insulation member 620 on the outside of the object device, and / or covered by the second heat insulation member 610 on the inside of the object device. The side portions 520 of the first heat insulation body 500-1 and / or the second heat insulation body 500-2 can be covered by the first heat insulation member 620 on the outside of the object device and / or covered by the second heat insulation member 610 on the inside of the object device.

[0102] Here, the second heat-insulating member 610 disposed between the assembly block 600 and the edge portion 530 may be formed with an insertion groove corresponding to the mating surface of the assembly block 600 and / or a third through hole corresponding to the first through hole formed in the edge portion 530. Thus, by sequentially passing through the second through hole formed in the first heat-insulating member 620, the first through hole formed in the edge portion 530, and the third through hole formed in the second heat-insulating member 610, and inserting into the insertion groove formed on the mating surface of the assembly block 600, not only can the first heat-insulating member 620 be joined to the assembly block 600, but the second heat-insulating member 610 and the edge portion 530 can also be joined to the assembly block 600.

[0103] On the other hand, the second heat insulation member 610 may have a shape that bends along the steps of the assembly block 600 and / or the heat insulation body 500 that are joined and closely abutted to the second heat insulation member 610, so as to have higher deformation strength. That is, the second heat insulation member 610 may have a shape that bends along a first step 531 formed between the center portion 510 and the side portion 520 of the inner side panel of the first heat insulation body 500-1 and the second heat insulation body 500-2, and a second step 532 formed between the side portion 520 and the edge portion 530. The second heat insulation member 610 may have a shape that bends along the shape of the assembly block 600 so as to closely abut between the edge portion 530 that bends along the second step 532 formed on the inner side panel of each of the heat insulation bodies 500-1, 500-2 and the assembly block 600.

[0104] In the above Figure 6 The description uses an example of an assembly block 600 disposed inside the object device, but the assembly block 600 can also be disposed outside the object device. Alternatively, the assembly block 600 can be disposed both inside and outside the object device.

[0105] On the other hand, as described Figure 6 and Figure 7 As shown, the second heat insulation member 610 may have a shape that is curved in a near-triangular shape. In this case, the second heat insulation member 610 may have a cross-section that is close to a triangle, with the center of the curvature of the edge portion 530 connecting the first heat insulation body 500-1 and the second heat insulation body 500-2, i.e., the outer shape corner of the object device, as the vertex between the two sides, and including a base portion 612 facing the interior angle of the vertex.

[0106] In this case, as described Figure 6 and Figure 7As shown, the second thermal insulation member 610 may have an extension 611 that extends from the corner of the external shape of the object device along each thermal insulation body 500-1, 500-2 beyond the bottom edge 612, thus having a longer length than the length extending from the apex along each thermal insulation body 500-1, 500-2 to the bottom edge 612. Therefore, cold air loss can be prevented by minimizing the thermal bridging effect.

[0107] On the other hand, in order to effectively distribute the loads such as atmospheric pressure or external forces applied to the insulation 500, the insulation 500 may have a support portion that further improves the structural strength.

[0108] The support portion may be formed to be inserted into and support the heat insulation body 500. The support portion may include a first frame for supporting a first plate 501 (top surface) of the heat insulation body 500 and / or a second frame for supporting a second plate 502 (bottom surface). The support portion may be formed as a column portion, the column portion including a column supporting the space between the first frame and the second frame.

[0109] On the other hand, the first plate 501 and / or the second plate 502 forming the insulation 500 may include steps (first step 531 and / or second step 532). Thus, the first plate 501 and the second plate 502 may have a step gradient that gradually moves closer to each other. Due to the shape of this first plate 501 and / or second plate 502, the insulation 500 can have a step gradient and can be divided according to the step gradient into a central portion 510 forming the thickest vacuum space, a side portion 520 forming a vacuum space thinner than the vacuum space of the central portion 510, and an edge portion 530 that does not form a vacuum space.

[0110] Therefore, the support portion for maintaining and / or supporting the internal space of the insulation 500 may include a first frame having a stepped gradient according to the shape of the first plate 501 having the stepped gradient. It may also include a second frame having a stepped gradient according to the shape of the second plate 502 having the stepped gradient. The support portion may be composed of a first support portion and / or a second support portion, the height of which supports the columns used to maintain the spacing between the first and second frames of the vacuum space varies according to the thickness of the vacuum space, which decreases as it extends from the center portion 510 to the side portion 520 due to the stepped gradient of the insulation 500.

[0111] For example, in the case of the central portion 510, where the vacuum space is thickest, a support portion having a first height for supporting a column between the first frame and the second frame can be configured according to the thickness of the vacuum space formed in the central portion 510. In this case, the support portion having the first height can be named the first support portion.

[0112] In the case where the thickness of the vacuum space in the side portion 520 is thinner than the thickness of the central portion 510, a support portion having a second height for supporting a column between the first frame and the second frame can be configured according to the thickness of the vacuum space formed in the side portion 520. In this case, the second height can be a lower height than the first height. The support portion having the column with the second height can be named the second support portion. In this case, the support portion inserted into the interior of the heat insulation body 500 to support the internal space, i.e., the vacuum space, can be composed of the first support portion and / or the second support portion.

[0113] Figure 8 This is an example diagram showing an example of a heat insulation body, a second heat insulation member, and / or a first heat insulation member having a support portion according to an embodiment of the present invention. Figure 9 This is an example diagram illustrating an example of a heat insulation body and / or the second heat insulation member and the first heat insulation member having a support portion according to another embodiment of the present invention.

[0114] First, such as Figure 8 As shown, in order to support the space (e.g., a vacuum space) formed inside the heat insulation body 500, the present invention may provide a support portion inside the heat insulation body 500. The support portion may extend into the interior of the center portion 510 and / or the side portion 520 of the heat insulation body 500. The support portion may be configured to support a portion of the side portion 520 formed in the first plate 501 and / or the second plate 502 (e.g., a portion to the first step 531 and / or the second step 532).

[0115] Therefore, the present invention can not only distribute the load applied to the center portion 510 of the insulation 500 to the first frame, second frame and / or column constituting the support portion, but also distribute the load applied to the side portion 520 to the first frame, second frame and / or column constituting the support portion. Referring hereafter... Figures 10 to 12 The structure of the support portion of the present invention, which is integrally formed as described above, supports not only the interior of the central portion 510 but also the interior of the side portion 520.

[0116] On the other hand, as described Figure 9As shown, in another embodiment of the present invention, the support portion may have a structure in which at least one shielding plate is disposed between the first frame and the second frame. In this case, the columns forming the column portion of the support portion may be formed in a configuration where at least one internal column formed in the at least one shielding plate is joined to each other. Referring hereafter... Figure 13 The structure of the support portion of this embodiment of the invention, which includes at least one shielding plate, will be described in further detail.

[0117] Figure 10 This is an example diagram illustrating an example of a heat insulation body configured with a support portion integrally formed to support not only the interior of the central portion 510 but also the interior of the side portion 520, according to an embodiment of the present invention. Figure 11 This is an example diagram showing the structure of the support portion.

[0118] First, refer to Figure 10 , Figure 10 An insulation body 500 is shown, which is divided into a central portion 510, a side portion 520 and an edge portion 530 according to a first plate and / or a second plate having a stepped gradient (e.g., two steps) formed in a direction that approaches each other. Figure 10 A first frame 1000 and / or a second frame 1010, configured inside the insulation 500 and / or having a stepped gradient according to the shape of the first plate and / or the second plate having the stepped gradient, are shown. Figure 10 An example is shown that includes a column portion 1020 supporting a column between the first frame 1000 and the second frame 1010, and a connecting groove 1030 formed in at least one of the first frame 1000 and the second frame 1010 in conjunction with the column.

[0119] like Figure 10 As shown, in order to prevent damage to the central portion 510 caused by lateral loads, the heat insulation body 500 of this embodiment of the invention may have a side portion 520 with a narrower gap between the first plate and the second plate than the central portion 510. Thus, the side portion 520 can form a vacuum space with a thickness thinner than the vacuum space formed inside the central portion 510.

[0120] On the other hand, based on the internal shape of the heat insulation body 500 with a side portion 520 formed between the edge portion 530 and the center portion 510, the support portion of this embodiment of the invention extends not only into the center portion 510 of the heat insulation body 500, but also into the side portion 520. The support portion can be formed to support a part of the side portion 520 formed in the first plate 501 and / or the second plate 502. That is, the support portion can be provided with a side portion support portion 1120, which extends from the center portion support portion 1110 supporting the interior of the center portion 510 of the heat insulation body 500, and is formed to support the interior of the side portion 520 of the heat insulation body 500. In this case, the support portion can be an integral configuration of the center portion support portion 1110 and the side portion support portion 1120.

[0121] like Figure 11 As shown, in order to form such an extended side support 1120, the first frame 1000 and / or the second frame 1010 of the support of the present invention may have frame steps 1100, 1101 corresponding to the first step of the first plate and / or the second plate. In this case, the frame steps 1100 of the first frame 1000 and the frame steps 1101 of the second frame 1010 may also be formed to be curved along an arcuate surface, thereby effectively distributing the side load.

[0122] As described above, since the first frame 1000 and the second frame 1010 form a stepped gradient in the direction they approach each other, the height of the columns supporting the first frame 1000 and the second frame 1010 can also vary. That is, the height (second height) of the column 1021 configured to support the inner region of the side portion 520, i.e., the side portion support portion 1120, can be lower than the height (first height) of the column 1020 configured to support the inner region of the center portion 510, i.e., the center portion support portion 1110.

[0123] On the other hand, if the first plate and / or the second plate are joined as a single plate at the location forming the second step, then no vacuum space will be formed between the first plate and the second plate. Therefore, as described... Figure 10 As shown, the support extending into the side portion 520 can extend to the region where the second step of the first plate and / or the second plate begins. The first frame 1000 and / or the second frame 1010 can extend to the region where the second step of the first plate and / or the second plate begins. A column of the second height can be disposed between a region of the extended first frame 1000 and a region of the second frame 1010, thereby forming a support for the extended regions of the first frame 1000 and the second frame 1010, i.e., the side portion support portion 1120.

[0124] That is, the central portion 510 of the support can be supported by the central support portion of the first frame 1000 and the central support portion of the second frame 1010. A column portion (first column portion) including a plurality of columns having the first height is disposed between the central support portion of the first frame 1000 and the central support portion of the second frame 1010. Thus, it is possible to support such that the interval between the central support portion of the first frame 1000 and the central support portion of the second frame 1010 is maintained at an interval corresponding to the first height.

[0125] The side portion 520 of the support can be supported by the side support portions of the first frame 1000 and the second frame 1010. A column portion (second column portion) including a plurality of columns having the second height is disposed between the side support portions of the first frame 1000 and the side support portions of the second frame 1010. Thus, it is possible to maintain a distance between the side support portions of the first frame 1000 and the side support portions of the second frame 1010 corresponding to the second height.

[0126] On the other hand, the first frame 1000 and the second frame 1010 can be in a grid shape composed of rows and columns with constant lateral and longitudinal spacing. At each intersection of the rows and columns forming the grid shape, columns supporting the spacing between the first frame 1000 and the second frame 1010 and / or joint grooves for inserting the columns can be formed. Thus, the columns of the column portion 1020 can be configured with constant lateral and longitudinal spacing, distributing the load applied to at least one of the first frame 1000 and the second frame 1010 throughout the first frame 1000 and the second frame 1010 connected by a plurality of the columns.

[0127] On the other hand, the column can be formed to protrude from either the first frame 1000 or the second frame 1010 toward the other. In this case, a joint portion, i.e., a joint groove, can be formed on the other side where the column is not provided, allowing each column to be inserted and joined.

[0128] Thus, a column protruding from either of the frames is inserted into a connecting groove formed in the other frame. Therefore, the column and the corresponding connecting groove can be joined. Through the joining of the column and the connecting groove, the first frame 1000 and the second frame 1010 can be joined to each other in a configuration that maintains a spacing based on the height of the column disposed between the first frame 1000 and the second frame 1010. The space formed by the spacing between the first frame 1000 and the second frame 1010 based on the height of the column can be formed as an internal space for heat insulation in the heat insulation body 500, such as a vacuum space.

[0129] However, when a column protrudes from either the first frame 1000 or the second frame 1010 and / or a joint groove for inserting the column is configured in the other frame, the first frame 1000 and the second frame 1010 are asymmetrical. Therefore, while they may have strong resistance to external forces in a particular direction, they are susceptible to external forces in the opposite direction. To overcome this drawback, the column and the joint groove can be alternately arranged on each frame.

[0130] Figure 12 This is an example shown according to an embodiment of the present invention, in which the first frame 1000 or the second frame 1010 forming the support portion are alternately and crosswise configured with columns and / or connecting grooves.

[0131] Reference Figure 12 , Figure 12 This is a diagram showing an example of a second frame 1010 not combined with the first frame 1000. (See diagram below.) Figure 12 As shown, in the second frame 1010 of an embodiment of the present invention, at each position where the horizontal lines (rows) and vertical lines (columns) forming the grid shape intersect, columns 1020 and connecting grooves 1030 can be alternately arranged along the rows or columns.

[0132] The column 1020 and the connecting groove 1030 can be cross-configured in the first frame 1000 and the second frame 1010. That is, if a column 1020 is formed in the first frame 1000, a connecting groove 1030 can be formed in the second frame 1010, and if a column 1020 is formed in the second frame 1010, a connecting groove 1030 can be formed in the first frame 1000.

[0133] Therefore, a portion of the plurality of pillars can protrude from the first frame 1000, and a portion of the plurality of mating grooves can be formed in the second frame 1010. Thus, the plurality of pillars protruding from the first frame 1000 can be inserted into and / or mated into the corresponding mating grooves of the second frame 1010. The remaining portions of the plurality of pillars can protrude from the second frame 1010, and a portion of the plurality of mating grooves can be formed in the first frame 1000. Thus, the plurality of pillars protruding from the second frame 1010 can be inserted into and / or mated into the corresponding mating grooves of the first frame 1000.

[0134] On the other hand, the first frame 1000 may have the same characteristics as the described Figure 12 The second frame 1010 shown is symmetrical in shape. That is, in the first frame 1000, columns 1020 and connecting grooves 1030 may be alternately arranged along rows or columns at various positions where the horizontal lines (rows) and vertical lines (columns) that form the grid shape intersect.

[0135] Here, each post protruding from the first frame 1000 and the second frame 1010 can be configured to correspond to a joint groove formed in the other frame. Each joint groove configured in the first frame 1000 and the second frame 1010 can be configured to correspond to a post protruding from the other frame.

[0136] Therefore, as Figure 12 The second frame 1010 and the first frame 1000, which has a symmetrical shape, can be joined together. Furthermore, the joined first frame 1000 and second frame 1010 can maintain a spacing based on the height of the columns configured between them.

[0137] On the other hand, as described above, the second frame 1010 can be formed with a step 1101 corresponding to the step gradient of the plate forming the bottom surface of the insulation 500, so as to support the interior space of the side portion 520 of the insulation 500. Similarly, the first frame 1000 can be formed with a step corresponding to the step gradient of the plate forming the top surface of the insulation 500, so as to support the interior space of the side portion 520 of the insulation 500.

[0138] In this case, as described Figure 12As shown, the column height (second height) of a portion (side support portion 1120) of the second frame 1010 with the stepped gradient can be lower than the column height (first height) of the other portions (center support portion 1110) without the stepped gradient. Similarly, the column height (second height) of a portion (side support portion 1120) of the first frame 1000 with the stepped gradient can also be lower than the column height (first height) of the other portions (center support portion 1110) without the stepped gradient.

[0139] Therefore, the gap between the first frame 1000 and the second frame 1010 with the stepped gradient can be narrower than the gap between the first frame 1000 and the second frame 1010 without the stepped gradient.

[0140] On the other hand, a reinforcing block 1210 for strengthening the frame may also be formed between at least one of the cells of the first frame 1000 or the second frame 1010. For example... Figure 12 As shown, the reinforcing block 1210 can strengthen a portion of the rows or columns forming the lattice structure by adding at least one connection between the rows or columns of a frame forming the lattice structure.

[0141] On the other hand, according to another embodiment of the invention, the support may further include at least one shielding plate for preventing the loss of cool air caused by thermal radiation. In this case, at least one of the shielding plates may be configured to be separated from the first frame 1000 or the second frame 1010 by a constant interval, parallel to the second frame 1010 or the first frame 1000.

[0142] Figure 13 This is an example diagram illustrating a configuration of a support portion formed between a first frame 1000 and a second frame 1010, according to another embodiment of the present invention, in a structure including at least one shielding plate.

[0143] Reference Figure 13 , Figure 13 An example is shown of a first frame 1000 and / or a second frame 1010 into which the individual columns formed as column sections can be inserted, arranged alternately at constant intervals. For example... Figure 13 As shown, two shielding plates 1301 and 1302 are formed between the first frame 1000 and the second frame 1010. The two shielding plates 1301 and 1302 can be configured to be parallel to the second frame 1010 and separated from the second frame 1010 by a constant interval.

[0144] On the other hand, such as Figure 13As shown, the shielding plate can be integrally formed with a connecting pin that can engage with other shielding plates. A recessed portion 1321 can be formed at one end of the connecting pin to engage with other connecting pins. A protruding connecting protrusion 1322 can be formed at the other end of the connecting pin to be inserted into the recessed portion 1321 of other connecting pins. The recessed portion 1321 and the connecting protrusion 1322 can be formed on each end side of the connecting pin with the shielding plate as the center.

[0145] Therefore, the first shielding plate 1301 and the second shielding plate 1302 can be joined together by inserting the respective engaging protrusions 1322 of the plurality of engaging pins formed on the first shielding plate 1301 into the recesses 1321 of the plurality of engaging pins formed on the second shielding plate 1302. In this case, at least a portion of the length of the engaging protrusions 1322 inserted into the recesses 1321 is constant, thereby allowing the first shielding plate 1301 to maintain a constant interval and / or be stacked on top of the second shielding plate 1302. That is, as Figure 13 As shown, multiple shielding panels can maintain a constant spacing and / or be stacked layer by layer by connecting pins formed on the shielding panels with constant lateral and longitudinal intervals.

[0146] On the other hand, as described Figure 13 As shown, the interlocking pins can function as pillars supporting the gap between the first frame 1000 and the second frame 1010. For example, the interlocking protrusion 1322 of the first or last interlocking pin, i.e., the interlocking pin located at the end, can be formed to insert and / or engage with the interlocking groove 1030 formed in the first frame 1000 or the second frame 1010. Thus, as Figure 13 As shown, the engagement protrusion 1322 of the engagement pin of the shielding plate (e.g., the second shielding plate 1302) initially stacked on the second frame 1010 can be inserted into and engaged with the engagement groove 1320 of the second frame 1010. Thus, the second shielding plate 1302 can be engaged on the second frame 1010.

[0147] In this way, such as Figure 13As shown, the engagement pin recesses 1321 of the second shielding plate 1302 can be fitted with the engagement pin protrusions 1322 of the first shielding plate 1301. Thus, the first shielding plates 1301, which are stacked at constant intervals on the second shielding plate 1302, can be joined. The engagement pin recesses of the first shielding plates 1301 can reach the inner surface of the first frame 1000 and support the first frame 1000. That is, as a plurality of shielding plates are stacked, the engagement pins formed on each shielding plate can, as they are joined together, function as pillars supporting the gap between the first frame 1000 and the second frame 1010.

[0148] On the other hand, based on the above description, an example has been described in which the columns and connecting grooves of the first frame 1000 and the second frame 1010 of the present invention are alternately arranged at a constant interval. Thus, as... Figure 13 As shown, the connecting slots can be alternately configured at constant intervals in the first frame 1000 and the second frame 1010.

[0149] As described above, with the connecting grooves alternately arranged at constant intervals in the first frame 1000 and the second frame 1010, the connecting pins of each shielding plate can also be... Figure 13 The configurations are alternately reversed. Specifically, in the case of the shielding plate in this embodiment, the engagement protrusion 1322 of the engagement pin corresponding to the position where the engagement groove is located in the second frame 1010 can be configured in a first direction pointing towards the second frame 1010. The engagement protrusion 1322 of the engagement pin corresponding to the position where the engagement groove is located in the first frame 1000 can be configured in a direction pointing towards the first frame 1000, i.e., a second direction opposite to the first direction.

[0150] In this case, since the recess 1321 is formed in the direction opposite to the direction in which the connecting protrusion 1322 is formed on the connecting pin, it can also be described that, in the case of the shielding plate of the embodiment of the present invention, the recess 1321 of the connecting pin corresponding to the position where the connecting groove is disposed in the second frame 1010 is disposed in a second direction pointing towards the first frame 1000. The recess 1321 of the connecting pin corresponding to the position where the connecting groove is disposed in the first frame 1000 is disposed in a first direction pointing towards the second frame 1010.

[0151] On the other hand, the above description illustrates that a plurality of shielding plates with connecting pins are stacked at constant intervals, the recesses of the connecting pins reaching the first frame 1000 or the second frame 1010, and the connecting pins that are engaged with each other support the interval between the first frame 1000 and the second frame 1010.

[0152] However, alternatively, a cross-shaped groove can be formed in the recess of each connecting pin to engage with the intersection of the grid-shaped rows and columns of the first frame 1000 or the second frame 1010. In this case, if the recess of the connecting pin reaches the first frame 1000 or the second frame 1010, the intersection of the rows and columns of the first frame 1000 or the second frame 1010 is inserted into the cross-shaped groove formed in the recess.

[0153] The above description illustrates a configuration where the shielding plate is integrally formed with a connecting pin that can be combined with other shielding plates and the first frame 1000 or the second frame 1010; however, the invention is not limited thereto. That is, the connecting pin and the shielding plate can be completely independent components.

[0154] For example, the shielding plate may include a plurality of through holes through which the pillars of the pillar portion 1020 supporting the gap between the first frame 1000 and the second frame 1010 can pass. In this case, each pillar of the pillar portion 1020 protruding from the first frame 1000 or the second frame 1010 can pass through the through holes formed in the shielding plate and engage with a groove formed in another frame. In this case, the shielding plate may include a spacer holding block for maintaining a constant interval when the shielding plates are stacked. The spacer holding block can keep the interval between the individual shielding plates constant when multiple shielding plates are stacked.

[0155] On the other hand, the above description describes a support portion in which a central support portion 1110 supporting the central portion 510 of the heat insulation body 500 and a side support portion 1120 extending from the central support portion 1110 and / or forming a support for the side portion 520 of the heat insulation body 500 are integrally formed. In contrast, it is also possible to have a structure in which the central support portion 1400 and the side support portion 1410 are each separated into different parts. Hereinafter, a support portion having this structure in which the central support portion 1400 and the side support portion 1410 are each separated into different parts will be referred to as a support portion according to another embodiment of the present invention.

[0156] Figure 14 This is an example diagram of a support portion formed with a central support portion and a side support portion according to another embodiment of the present invention.

[0157] Reference Figure 14An example of a heat insulation body according to an embodiment of the present invention, including a central portion 510, a side portion 520, and / or an edge portion 530, is shown. In this case, a central support portion 1400 for supporting the gap between a first plate and a second plate forming a vacuum space of the heat insulation body may be disposed inside the central portion 510. A side support portion 1410 for supporting the gap between the first plate and the second plate to maintain the vacuum space formed inside the side portion 520 may be disposed inside the side portion 520. The central support portion 1400 and the side support portion 1410 may be formed to be separable from each other.

[0158] On the other hand, as described above, the first plate and the second plate are curved along an arcuate surface to form a step in a direction that brings them closer to each other. Therefore, a vacuum space with a thinner thickness than the vacuum space formed inside the central portion 510 can be formed inside the side portion 520. Consequently, the interval between the first plate and the second plate inside the side portion 520 can be smaller than the interval between the first plate and the second plate formed in the central portion 510.

[0159] Therefore, as shown in the figure Figure 14 A three-dimensional view of the structural support component. Figure 15 And show the enlarged version Figure 15 Enlarged view of a portion of the support section Figure 16 As shown, the structures of the central support portion 1400 and the side support portion 1410 may be different from each other.

[0160] That is, such as Figure 16 As shown, the central support portion 1400 includes a first frame and a second frame and / or columns for maintaining the interval between the first frame and the second frame. That is, the inner sides of the first and second plates of the central portion 510 can be supported initially by the first and second frames having a lattice structure. The interval between the first and second frames is supported by the columns, thereby allowing the central portion 510 to maintain a constant interval.

[0161] On the other hand, unlike this configuration, the side support portion 1410 may have a configuration including a central frame 1411 forming a grid shape and / or protrusions 1412 protruding from the central frame 1411 in the vertical direction. In this case, since the central frame 1411 has a grid shape with intersecting rows and columns, the protrusions 1412 may protrude at various positions where the rows and columns intersect.

[0162] Here, the protrusion 1412 may be a component supporting the inner side surface of the side portion 520 of the heat insulation body formed by the step gradient in the first and second plates. In this case, the protrusion 1412 is used to support the gap between the first and second plates for forming a vacuum space in the side portion 520 of the heat insulation body, and the vertical protrusion length of the protrusion 1412 may be shorter than the length of the column supporting the gap between the first frame and the second frame of the central support portion 1400.

[0163] As described Figure 16 As shown, the central frame 1411 of the side support portion 1410 can be disposed between the first frame and the second frame of the central support portion 1400. Therefore, the central frame 1411 may not contact the edges of the first frame and / or the edges of the second frame.

[0164] On the other hand, as described above, the central support portion 1400 and the side support portion 1410 can be formed in a structure that is separate from each other. That is, Figure 17 An example of this is shown.

[0165] Reference Figure 17 (a), such as Figure 17 As shown in (a), the central support portion 1400 can be disposed inside the heat insulation body, depending on the structure of the heat insulation body 500 with the side portion 520 disposed at the edge of the central portion 510.

[0166] However, as mentioned above Figure 16 As described, the central frame 1411 of the side support portion 1410 can be disposed between the first frame and the second frame of the central support portion 1400, without contacting the first frame and / or the second frame. That is, the side support portion 1410 may not be supported by the central support portion 1400, such as... Figure 17 As shown in (b), they can have structural forms that are completely separate from each other.

[0167] Figure 18 An example cross-section of the heat insulation 1800, which is shown in another embodiment of the present invention, is provided by a central support portion 1400 and a side support portion 1410 formed in this structure.

[0168] Reference Figure 18 The heat insulation 1800 may include a central portion 510 with a vacuum space formed on its inner side, a side portion 520 extending from the central portion 510, and / or an edge portion 530 without a vacuum space formed, depending on the first plate 501 and / or the second plate 502 having a stepped gradient.

[0169] In this case, a central support portion 1400, including a first frame 1801, a second frame 1802, and / or a column 1803 supporting the interval between the first frame 1801 and the second frame 1802, can be disposed inside the central portion 510. The inner space of the central portion 510, where a vacuum space is formed, can be supported by the interval between the first frame 1801 and the second frame 1802, which is maintained according to the height of the column 1803.

[0170] On the other hand, a side support portion 1410, including a central frame 1411 and / or a plurality of protrusions 1412 protruding vertically from the central frame 1411, may be disposed on the inner side of the side portion 520. In this case, the distance between the extended region of the first plate 501 forming the inner region of the side portion 520 and the extended region of the second plate 502 forming the inner region of the side portion 520 can be supported according to the length of the protrusions 1412 protruding vertically from the central frame 1411.

[0171] Here, the side support portion 1410 and the center support portion 1400 can have a structure that is not connected to each other and is separate from each other. That is, as... Figure 18 As shown, the central frame 1411 of the side support portion 1410 is located between the first frame 1801 and the second frame 1802 of the central support portion 1400, so that the frames can be configured not to overlap each other.

[0172] On the other hand, as described above, the inner regions of the central portion 510 and the side portion 520 can form an air pressure lower than the external air pressure. For example, the inner regions of the central portion 510 and the side portion 520 can be vacuum regions. Therefore, the central portion 510 and the side portion 520 may receive external forces caused by the pressure difference from the outside.

[0173] On the other hand, each support portion can support the interior of the heat insulation body 1800 to prevent the shape of the heat insulation body 1800 from collapsing due to the external force caused by this pressure difference. In this embodiment of the invention, the heat insulation body 1800 is bag-shaped; therefore, the support portions inside the bag-shaped heat insulation body 1800 can be combined by the external force to form the first plate 501 and the second plate 502 of the shell of the heat insulation body 1800. That is, the first plate 501 and the second plate 502 can be pressed tightly against the side support portion 1410 and the central support portion 1400 by external force, and the side support portion 1410 and the central support portion 1400 can be combined.

[0174] Therefore, as Figure 18As shown, even if the side support portion 1410 is not connected to the central support portion 1400 but is supported by the central support portion 1400, it can still be joined to the inside of the side portion 520 by the external force caused by the air pressure difference. With the engagement of the side support portion 1410, the gap between the region of the first plate 501 that constitutes the extension of the side portion 520 and the region of the second plate 502 that constitutes the extension of the side portion 520 can be supported by the protrusion 1412 protruding from the central frame 1411 of the side support portion 1410.

[0175] On the other hand, the above description illustrates the case where the insulation has a first step 531 and / or a second step 532, but the present invention is not limited thereto. That is, the insulation can have more than three step gradients.

[0176] Here, when the insulation has three or more step gradients, the first frame and / or second frame of the support portion may have step gradients corresponding to the respective steps of the three or more insulation components. In this case, the height of the columns supporting each region of the first and second frames can vary according to the three or more step gradients. That is, depending on the step gradient, the thicker the vacuum space, the higher the height of the columns used to maintain the gap between the first and second frames can be to maintain the thickness of the vacuum space. In other words, the height of the columns used to maintain the gap between the first and second frames can vary depending on the thickness of the different vacuum spaces of the insulation formed according to the step gradient.

[0177] Alternatively, as in another embodiment of the invention described above, the support portion can be divided into a plurality of parts according to the step gradient. In this case, each part may have a first frame, a second frame, and columns that support the first frame and the second frame, each distinct from the others. Here, since the thickness of the vacuum space for thermal insulation in each part is different according to the respective step gradient, the height of the columns may vary in each part.

[0178] As an example, in the above Figures 15 to 18 The text describes a configuration where the side support directly supports the first and / or second plates via a support portion protruding from the central frame. However, unlike this, the side support can also be configured similarly to the central support, consisting of a first frame, a second frame, and a column portion including a plurality of columns supporting the space between the first and second frames.

[0179] On the other hand, while specific embodiments have been described in the above description of the present invention, various modifications can be made without departing from the scope of the invention. Therefore, the detailed description above should not be construed as limiting in all respects, but rather as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention should fall within the scope of the invention.
