Description

Insulator

[0001] The present invention relates to an insulator.

[0002] First, there is the applicant's registered patent No. 10-0343719 (Patent Document 1). According to this patent, a vacuum adiabatic panel is manufactured, embedded in the wall of a refrigerator, and the exterior of the vacuum adiabatic panel is finished with a separate molded Styrofoam material. This method eliminates the need for foaming and improves insulation performance. However, this method has the drawback of increasing costs and complicating the manufacturing process.

[0003] As another example, there have been attempts to fabricate the entire refrigerator wall as a single vacuum insulator. For example, U.S. Patent Publication No. US2040226956A1 (Patent Document 2) discloses a method for providing vacuum insulation for a refrigerator. However, it is difficult to achieve a practical level of insulation by providing a sufficiently vacuumed refrigerator wall. Specifically, there are several problems, including the difficulty in preventing heat transfer at the contact point between the outer and inner cases, which have different temperatures, the difficulty in maintaining a stable vacuum state, and the difficulty in preventing deformation of the case due to negative vacuum pressure.

[0004] Japanese Patent Application Laid-Open No. 2011-247534 (Patent Document 3) discloses an insulation box that simplifies the bonding work and improves productivity when installing and preparing multiple vacuum insulation panels.

[0005] Patent Document 3 discloses an insulating case of a refrigerator comprising an inner case and an outer case and a plurality of vacuum insulation panels provided between them, and forming a plurality of wall sections of a refrigerator body, wherein the inner case is formed by combining a plurality of inner case partitions into which the entire inner case is divided, and at the same time, a plurality of vacuum insulation panels are formed in a shape corresponding to each inner case partition, and each of these vacuum insulation panels and each of the inner case partitions is installed.

[0006] Conventional insulators had problems with deformation due to vacuum pressure and deformation caused by internal refrigerator shelves and loads.

[0007] Conventional insulators have problems with structural strength and insulation performance at corners or where multiple insulators are connected.

In the present invention, examples of connection can be support, combine, and seal, which will be described later. In the present invention, the support of object A by object B can be defined as that object A is restricted from moving in one or more of the +X, -X, +Y, -Y, +Z, and -Z axis directions by object B. In the present invention, examples of support can be combination and seal, which will be described later. In the present invention, it can be defined that object A is combined with object B, meaning that object A is restricted from moving in one or more of the X, Y, and Z-axis directions by object B. In the present invention, an embodiment of the combination can be a sealing, which will be described later. In the present invention, it can be defined that object A is sealed with object B, meaning that movement of fluid is not permitted at a portion where object A and object B are connected. In the present invention, at least one object, that is, at least a part of object A and object B, can be defined as including a part of object A, the entirety of object A, a part of object B, the entirety of object B, a part of object A and a part of object B, a part of object A and the entirety of object B, the entirety of object A and a part of object B, and the entirety of object A and the entirety of object B. In the present invention, it can be defined that plate A can be a wall defining space A, meaning that at least a part of plate A can be a wall forming at least a part of space A.That is, at least a part of plate A may be a wall forming space A, or plate A may be a wall forming at least a part of space A. In the present invention, the central part of an object may be defined as a part located in the center of the third part when the object is divided into three parts based on the longitudinal direction of the object. The periphery of an object may be defined as a part located on one or the other side of the central part of the third part. The periphery of an object may include a surface in contact with the central part and a surface opposite thereto. The opposite surface may be defined as the border or edge of the object. In the present invention, the degree to deformation resistance indicates the degree to which an object resists deformation, and may be defined as a value determined by the shape including the thickness of the object, the material of the object, and the processing method of the object. In the present invention, the degree of heat transfer resistance indicates the degree to which an object resists heat transfer, and may be defined as a value determined by the shape including the thickness of the object, the material of the object, and the processing method of the object. In the present invention, the heat transfer resistance can be defined as the sum of at least one or at least two of the degree of conduction resistance, the degree of radiation resistance, and the degree of convection resistance. The terms “upper side,” “lower side,” “right side,” “left side,” “front side,” and “rear side” used in the following description will be understood through the coordinate system illustrated in FIGS. 1 and 5. An example of “+Z” means “upper side,” an example of “-Z” means “lower side,” an example of “+Y” means “right side,” an example of “-Y” means “left side,” an example of “+X” means “front side,” and an example of “-X” means “rear side.”The forward and backward direction used in this specification may be an example of the X-axis direction, the left and right direction may be an example of the Y-axis direction, and the up and down direction may be an example of the Z-axis direction.

[0096] The insulator (10) of the present invention can be applied to a refrigerator (1). The refrigerator (1) may include a main body (2) provided with a cavity (9) capable of storing stored items, and a door (3) provided to open and close the main body (2). A cold source for supplying cold air (Cold) to the cavity (9) may be provided. For example, the cold source may be an evaporator (7) that evaporates a 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.

[0097] In the present invention, the third plate (16) can reduce the wall forming the insulator (10) from being deformed, sunken, or collapsed toward the inside of the vacuum space (15).

[0098] The wall forming the insulation (10) may include a first plate (11) and a second plate (12). The third plate (16) may be placed on at least one of the first plate (11) and the second plate (12).

[0099] The third plate (16) may be placed on a thinner portion of the first plate (11) and the second plate (12). The third plate (16) may be placed on a weaker portion of the first plate (11) and the second plate (12).

[0100] The third plate (16) can be placed on at least one side among the inner and outer sides of the vacuum space (15).

[0101] The third plate (16) may be arranged on at least one curved portion of the first and second plates (11, 12). The third plate (16) may be arranged on at least a portion of the periphery of the vacuum space (15) or the first and second plates (11, 12). The third plate (16) may be arranged spaced apart from the periphery insulation covering the vacuum space (15) or the first and second plates (11, 12). The third plate (16) may be arranged on at least a portion of the periphery insulation covering the vacuum space (15) or the first and second plates (11, 12). The third plate (16) may be arranged to extend to the outermost bar among a plurality of bars arranged inside the first and second plates (11, 12). The third plate (16) can extend to a portion of at least one of the bends (11b, 12c) of the first and second plates (11, 12).

[0102] The third plate (16) may have a thickness thinner than one of the first and second plates (11, 12). The third plate (16) may have portions with different thicknesses. The third plate (16) may have portions with variable thicknesses. The third plate (16) may have long, winding portions in consideration of the heat conduction path.

[0103] The third plate (16) may include a portion having a grid-like shape. The third plate (16) may include a portion having one side cut out.

[0104] The third plate (16) may have a thin thickness (16b) in a portion overlapping with the supporter set grid. The third plate (16) may have a thick thickness (16a) in a portion not overlapping with the supporter set grid. In a portion where the third plate (16) and the supporter set grid overlap, the density of the supporter set grid can be reduced. The supporter set grid may be a set grid including a plurality of bars (20) and support plates (22a, 22b).

[0105] The third plate (16) can be placed between the supporter set support plate and at least one of the first and second plates (11, 12).

[0106] In Fig. 6, an example is shown in which the first and second plates (11, 12) are supported by two bars.

[0107] Referring to Fig. 6, the third plate (16) may be positioned to be inserted into the inner or outer side of the first plate (11). The third plate (16) may extend to cover at least a portion of the outermost bar. This prevents damage or deformation due to sagging of the first plate (11).

[0108] 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 portion (11b) of the first plate (11). The third plate (16) may have a surface that is at least partially connected to the first portion (11a) of the first plate (11).

[0109] A reinforcing member (40) may be provided on one side of the second plate (12). The reinforcing member (40) may be arranged on one side of the insulator (10), or may have a portion that is bent to facilitate strength reinforcement. Since the reinforcing member (40) may be arranged on one corner of the second plate (12), it may also be referred to as a corner frame. When at least two insulators (10) are coupled to each other, the reinforcing member (40) may be arranged between the second plate (12) of the first insulator (10) and the second plate (12) of the second insulator (10). By the reinforcing member (40), the strength of the second plate (12) itself may be reinforced, and the strength may be reinforced between the first and second insulators (10). The reinforcing member (40) may, for example, be arranged on the third portion of the second plate (12). The reinforcing member (40) can be inserted into a portion of the third section where one side is more bent.

[0110] The second plate (12) may include a first portion (12a) forming one side of the vacuum insulation portion, and a second portion (12b) extending further from the first portion (12a).

[0111] The second plate (12) may include a third portion (12c) that is bent from the second portion (12b). The third portion (12c) may be formed such that one side is further bent. As a result, the second plate (12) may be reinforced in its shape by forming a structure that is bent twice.

[0112] At least two insulators (10) can be joined to each other between the second plates (12) having a double-folded structure on one side. As a result, strength reinforcement can be achieved at the portion where at least two insulators (10) are joined.

[0113] In Fig. 7, an example is shown in which the third plate (16) is positioned so as not to cover the outermost bar (20) and the bar (20) adjacent thereto. The third plate (16) may be positioned so as to extend from the outermost side to between the second and third bars (20).

[0114] A block (30) may be provided on one side of the insulator (10). The block (30) may include a non-vacuum insulation portion. The block (30) may further include a portion that covers or joins the non-vacuum insulation portion.

[0115] The third plate (16) may not overlap with the block (30) in the longitudinal direction of the insulator (10), or may be spaced apart from it. This makes it possible to reduce heat transfer from the third plate (16) to the block (30).

[0116] The third plate (16) may not extend to the edge of the first plate (11). This allows heat transfer from the third plate (16) to the second plate (12) through the first plate (11).

[0117] Optionally, the insulator (10) of the present invention may include a support for maintaining a vacuum space (15). The support may include a bar (20) and a support plate (22a, 22b). The bar (20) may extend in the thickness direction of the vacuum space (15). The support plate (22a, 22b) may be connected to at least one of the first plate (11) and the second plate (12). The support plate (22a, 22b) may connect a plurality of bars (20) to each other.

[0118] Optionally, the insulator (10) of the present invention may include a radiation resistance sheet (23) that reduces heat transfer by radiation. The radiation resistance sheet (23) may be formed in parallel with the longitudinal direction of one of the first and second plates (11, 12) in the vacuum space (15). A plurality of radiation resistance sheets (23) may be provided.

[0119] In Fig. 8, an example is shown in which the third plate (16) extends past the outermost bar (20) to one side of the first plate (11). For example, when the third plate (16) extends to the position where the block (30) is installed and to the edge of the first plate (11), deformation may occur in the outermost bar (20) due to the third plate (16). In particular, when exhausting at a high temperature to form a vacuum space (15), deformation may occur in the edge due to deformation of the first plate (11).

[0120] That is, it is preferable that the third plate (16) does not extend to the edge of the first plate (11). In this way, the third plate (16) can be spaced apart from the edge of the first plate (11). This prevents deformation or damage to the outermost bar (20) of the insulator (10), the bar (20) adjacent thereto, or the area near the edge of the insulator (10).

[0121] Referring to Fig. 9, the third plate (16) can be formed to have a cut portion (16e) in which one side is cut.

[0122] The third plate (16) can be cut from one side of the insulator (10). The third plate (16) can be cut from one side at a portion where the block (30) of the first plate (11) is installed or at a portion where the insulators (10) are joined to each other. The cut portion (16e) of the third plate (16) can be spaced apart from the block (30).

[0123] Referring to FIG. 10, optionally, the third plate (16) may have grid-shaped ribs (16b, 16c, 16d).

[0124] Optionally, at least two insulators (10) may be provided in an intersecting direction. This may facilitate the installation of a block (30) on one side between the insulators (10) that are connected to each other.

[0125] At least two insulators (10) may have difficulty installing blocks (30) in the area between them, i.e., the corners. The corners where the door and the body meet may also include areas where the decoration is attached. As such, the area between the insulators (10) may have areas vulnerable to insulation.

[0126] Accordingly, when the third plate (16) is provided with grid-shaped ribs (16b, 16c, 16d), the amount of heat transfer through the third plate (16) can be reduced due to the space between the ribs (16b, 16c, 16d). As a result, the insulation performance in areas vulnerable to insulation, such as the corners of the insulator (10), can be improved.

[0127] The third plate (16) can be formed in a plate shape, a grid shape, or can be formed to include a plate-shaped portion and a grid-shaped portion.

[0128] Referring to Fig. 10, the third plate (16) may include a plate portion (16a) and a grid portion.

[0129] The plate-shaped portion may include a plate portion (16a). The grid-shaped portion may include grid-shaped ribs (16b, 16c, 16d).

[0130] The plate portion (16a) can form an inner or outer portion provided between the edges of the third plate (16). The plate portion (16a) can have a thickness greater than that of the first plate (11). The plate portion (16a) can have a thickness less than that of the second plate (12) or can have the same thickness as that of the second plate (12).

[0131] The plate (16a) can have a predetermined thickness and area.

[0132] The grid portion may be provided 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) provided as a grid that forms the edge of the third plate (16).

[0133] FIG. 10 shows an example in which a plate portion (16a) is formed on the inner or outer portion provided between the edge sides, and grid portions (16b, 16c, 16d) are provided on four sides of the plate portion (16a).

[0134] The grid-shaped ribs are formed to include first and second grids and a border grid, so that the amount of heat transfer passing through the third plate (16) can be reduced by the space between the first and second grids and the border grid. As a result, the insulation performance in areas vulnerable to insulation, such as the corners of the insulator (10), can be improved.

[0135] In Fig. 11, a third plate (16) including grid-shaped ribs (16b, 16c, 16d) and a plate portion (16a) is shown.

[0136] The third plate (16) is arranged on the supporter. The third plate (16) may be arranged so as to overlap with the block (30) on one side where the grid-shaped ribs (16b, 16c, 16d) are provided. The block (30) may have a portion that does not overlap with or is spaced apart from the plate portion (16a) of the third plate (16).

[0137] By this structure, strength reinforcement can be achieved on one side of the insulation (10) where the block (30) is placed. The deterioration of insulation performance due to conduction can be reduced by the space between the grid-shaped ribs (16b, 16c, 16d).

[0138] The lattice ribs (16b, 16c, 16d) may be arranged to overlap with the supporter. The lattice ribs (16b, 16c, 16d) may be arranged to overlap with the bar (20). Optionally, the lattice ribs (16b, 16c, 16d) may have a portion that is parallel to the extension direction of the support plate (22a, 22b) that supports the bar (20). As a result, strength reinforcement can be provided in the insulator (10) on which the bar (20) is arranged.

[0139] Optionally, the grid-shaped ribs (16b, 16c, 16d) may have a wider spacing than the support plates (22a, 22b) supporting the bars (20). The spacing between the first grids may be a wider spacing than the spacing between the support plates (22a, 22b) supporting the bars (20). The spacing between the second grids may be a wider spacing than the spacing between the support plates (22a, 22b) supporting the bars (20). Referring to FIG. 11, the grid-shaped ribs (16b, 16c, 16d) may be formed to have spacings that are approximately two or three times wider. As a result, the deterioration of the insulation performance due to conduction caused by the space between the grid-shaped ribs (16b, 16c, 16d) may be reduced.

[0140] Optionally, the thickness of the grid-shaped ribs (16b, 16c, 16d) may be provided to be thinner than the thickness of the plate (16a), so that the insulation performance on one side of the insulator (10) can be improved.

[0141] In FIG. 12 and FIG. 13, an example is shown in which a third plate (16) having different thicknesses is provided on the first plate (11).

[0142] Optionally, the third plate (16) may have portions having 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) that is positioned farther from the edge of the insulator (10). The second plate portion (16a) may be a portion of the third plate (16) that is positioned closer to the edge of the insulator (10). The second plate portion (16a) may be formed as a separate member from the first plate portion (16a). It is preferable that the third plate (16) be formed thinly in a portion adjacent to the edge of the insulator (10) to minimize deterioration of the insulation performance. The first plate portion (16a) may be formed thicker than the second plate portion (16a). For 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 that overlaps the block (30). It is preferable that the second plate portion (16a) be formed so as to extend the heat conduction path. The second plate portion (16a) may not extend to the edge of the insulator (10). The second plate portion (16a) may have a portion that is parallel to the first portion of the first plate (11).

[0143] Optionally, the third plate (16) may have a portion spaced apart from the block (30) arranged on one side of the insulator (10). The third plate (16) may have a portion spaced apart from the block (30) arranged on one side of the insulator (10).

[0144] In Fig. 14, the effect of improving heat transfer by reducing or removing the third plate (16) or by having a structure with grid-shaped ribs (16b, 16c, 16d) is shown.

[0145] When the third plate (16) is shortened by approximately 50 mm, a heat transfer improvement effect of 2.5% can be confirmed. In comparison to when the third plate (16) is shortened by approximately 50 mm, when the third plate (16) is shortened by approximately 60 to 90 mm, it can be confirmed that the heat transfer improvement effect is not significantly displayed. Therefore, it is preferable to shorten the third plate (16) by approximately 50 mm.

[0146] FIGS. 15 to 17 illustrate examples in which heat conduction can be minimized by expanding the pitch between a plurality of bars (20). The support plates (22a, 22b) may be formed in a lattice structure having a portion extending in a first direction and a portion extending in a second direction intersecting the first direction. The plurality of bars (20) may be arranged at the intersections of the portions extending in the first direction and the portions extending in the second direction of the support plates (22a, 22b). The plurality of bars (20) may be alternately arranged at the intersections of the portions extending in the first direction and the portions extending in the second direction. That is, the plurality of bars (20) may be arranged at 13 intersections out of a total of 25 intersections. As a result, the pitch of the bars (20) in the portion where the third plate (16) is arranged may be increased. Compared to a structure in which bars (20) are placed at all intersections out of a total of 25 intersections, a structure in which bars (20) are placed at 13 intersections out of a total of 25 intersections can improve the average pitch from 23 mm to 32 mm. Therefore, referring to the graph of Fig. 17, when the coverage is 100%, a thermal conductivity improvement effect of 7.5% can be confirmed. Due to the pitch expansion of multiple bars (20), thermal conductivity can be minimized without developing a separate mold. Since the pitch expansion area has a coverage of 46%, a thermal conductivity improvement effect of 3.5% can be confirmed.
