[0006] According to the present disclosure, the vacuum heat insulating material can be reinforced. [Brief explanation of the drawing]

[0008] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived of this disclosure, there was a technology for creating a storage container by forming an inner box with a storage chamber inside, and an outer box that surrounds the inner box with insulating material in between. In some such storage containers, vacuum insulating material is attached to plate-like members that form each side of the outer box.

[0009] However, the inventors discovered a problem: when the vacuum insulation material is a long component, there is a risk that the vacuum insulation material may bend in the middle of its longitudinal direction during the process of forming the outer box. To solve this problem, the subject matter of this disclosure was established. Therefore, this disclosure provides a storage container that can reinforce vacuum insulation material.

[0010] The embodiments will be described in detail below with reference to the drawings. However, unnecessary details may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. This is to avoid the following explanation becoming unnecessarily verbose and to facilitate understanding for those skilled in the art. The attached drawings and the following description are provided to enable those skilled in the art to fully understand this disclosure and are not intended to limit the subject matter described in the claims.

[0011] (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 7. In this description, unless otherwise specified, directions such as front, back, left, right, and up and down refer to the same directions relative to the storage unit 1 when it is installed and used on the installation surface. In each figure, the symbol LH indicates the left side of the storage unit 1 when it is installed and used, the symbol FR indicates the front of the storage unit 1, and the symbol UP indicates the top of the storage unit 1. In the installed state of the storage unit 1, the up and down direction coincides with the vertical direction, and the front, back, left, and right directions coincide with the horizontal direction. [1-1. Structure] [1-1-1. Storage Room Configuration]

[0012] Figure 1 is a perspective view of a storage unit 1 according to an embodiment of the present invention. As shown in Figure 1, the storage unit 1 is a refrigerator comprising an insulated box body 10 with an opening 14 on the front, a plurality of doors 16, 17, and 18 attached to the insulated box body 10, and a refrigerator that forms a refrigeration cycle. The storage unit 1 is formed in the shape of a rectangular parallelepiped, with its longitudinal direction extending along the vertical direction.

[0013] The insulated box body 10 is a box-shaped member that has thermal insulation properties and forms the main body of the storage unit 1. This insulated box body 10 comprises an outer box 12 that opens to the front, an inner box 13 housed inside the outer box 12 and also opening to the front, and a foamed insulation material 11 provided between the outer box 12 and the inner box 13.

[0014] The inner box 13 is formed from a hard resin such as ABS. In the insulated box 10, an opening provided in the inner box 13 functions as an opening 14 of the insulated box 10. The space inside the inner box 13 is cooled by a refrigerator and functions as a storage room 15 capable of freezing and refrigerating specified items. This storage room 15 is partitioned into a plurality of spaces by partition portions. In the present embodiment, each space partitioned in this way functions as a refrigerator compartment, a freezer compartment, and a vegetable compartment in order from above to below, for example.

[0015] As described above, the opening 14 of the heat insulation box body 10 is closed by a plurality of doors 16, 17, and 18. All of these doors 16, 17, and 18 are heat insulation doors provided with heat insulation members inside. In the storage 1, the opening of the inner box 13 located in the refrigerator compartment is closed by a pair of doors 16. These doors 16 are double-opening doors that can be opened and closed by rotating along the left-right direction of the storage 1. In the storage 1, the openings of the inner box 13 located in the vegetable compartment and the freezer compartment are closed by doors 17 and 18, respectively. These doors 17 and 18 are drawer-type doors that can be opened and closed by sliding along the front-rear direction of the storage 1.

[0016] Between the outer box 12 and the inner box 13, a foamed heat insulation material 11, which is a filling material, is filled. For the foamed heat insulation material 11, a rigid urethane foam or the like, which is a material that can be foamed and filled, is used. The rigid urethane foam can be easily foamed, self-adheres to various materials, and has high airtightness. In the storage 1, a rigid urethane foam is foamed and filled as the foamed heat insulation material 11 between the outer box 12 and the inner box 13, and self-adheres to the outer box 12 and the inner box 13. Note that the storage 1 is not limited to this, and any heat insulation material that can be heat-insulation filled may be used.

[0017] [[ID=X]][1-1-2. Structure of the outer box] FIG. 2 is an exploded perspective view of the outer box 12. In FIG. 2, for convenience of explanation, the inner box 13 and the vacuum heat insulation material 60 are shown by a two-dot chain line. As shown in FIG. 2, the outer box 12 includes a pair of side plates 20 that form the side surfaces of the heat insulation box body 10 in the left-right direction, a bottom plate 21 that forms the bottom surface of the heat insulation box body 10, a back plate 22 that forms the back surface of the heat insulation box body 10, and a top plate 23 that forms the top surface of the heat insulation box body 10. " [[ID=X]]

[0018] Each of the side panels 20 is a rectangular flat plate member in plan view. The side panels 20 are provided with flat side portions 28 that form the sides of the outer box 12. The side portion 28 has an outer surface 28A that faces outward from the insulated box 10 and an inner surface 28B that faces inward from the inner box 13. The side panels 20 are arranged such that the longitudinal direction of the side portion 28 extends along the vertical direction.

[0019] Each of the side panels 20 is provided with a flange portion 24 rising from the edge located at the front end of the side portion 28, a flange portion 25 rising from the edge located at the rear end of the side portion 28, and a flange portion 26 rising from the edge located at the lower end of the side portion 28. The flange portions 24, 25, and 26 all rise toward the other side panel 20 with a predetermined width dimension.

[0020] Each flange portion 24 located on the front side of the insulated box body 10 is connected to the edge of the opening of the inner box 13, forming the opening 14 of the insulated box body 10. These flange portions 24 function as contact surfaces to which sealing materials such as gaskets provided on the inner box 13 side of each door 16, 17, and 18 adhere.

[0021] The back panel 22 is a rectangular flat plate member in plan view. The back panel 22 is provided with a number of injection holes 27, which are through holes that penetrate in the thickness direction of the panel. When assembling the insulated box 10, foamed insulation material 11 is injected between the outer box 12 and the inner box 13 through these injection holes 27.

[0022] The bottom plate 21 is formed by bending a substantially rectangular plate-like member. The bottom plate 21 includes a bottom portion 30 located on the front end side of the bottom plate 21 and forming the bottom surface of the heat-insulating box body 10, an upright portion 32 rising upward from the rear end of the bottom portion 30, and an extension portion 34 extending rearward from the upper end of the upright portion 32.

[0023] The bottom plate 21 and the side plates 20 are connected to each other by fixing their respective edges located in the left-right direction on the bottom portion 30 and their respective flange portions 26 with fixing members such as screws. As a result, each of the side plates 20 is positioned upright from the left and right edges of the bottom portion 30.

[0024] Each of the side panels 20, when connected to the bottom portion 30, extends behind the rear end of the bottom portion 30 in the front-to-back direction, covering the rear end of the extension portion 34 from both sides in the left-to-right direction. As a result, the corners of the outer box 12 formed by the bottom and back surfaces are provided with outer box recesses 3 that curve inward toward the inner box 13. The space inside the outer box recess 3 is surrounded by the upright portion 32, the extension portion 34, and the side panels 20, and functions as a machine room where various components of the refrigeration unit, such as heat exchangers, are housed.

[0025] The bottom plate 21 and the back plate 22 are connected to each other by fixing the edge located at the rear end of the extension portion 34 and the lower end of the back plate 22 with a fixing member such as a screw. As a result, the back plate 22 is positioned upright from each of the edges located at the rear end of the extension portion 34.

[0026] Each of the side panels 20 and the back panel 22 are connected to each other by fixing them with a screw member or the like, with the flange portion 25 located at the rear end of each of the side panels 20 in contact with the edges located at both the left and right ends of the back panel 22.

[0027] The top panel 23 is formed by bending a roughly rectangular plate-like member. The top panel 23 includes a top surface portion 40 located on the front end side of the top panel 23 and forming the top surface of the insulated box body 10, an upright portion 42 extending downward from the rear end of the top surface portion 40, and an extension portion 44 extending rearward from the lower end of the upright portion 42.

[0028] The top surface 40 is provided with a storage hole 45, which is a through-hole that penetrates in the thickness direction of the plate. As shown in Figure 1, a storage body 48 that houses a control unit 46 equipped with electrical components such as a control board is housed in the storage hole 45.

[0029] As shown in Figure 2, the bottom plate 21 and the back plate 22 are connected to each other by fixing the edge located at the rear end of the extension portion 44 and the lower end of the back plate 22 with a fixing member such as a screw. As a result, the back plate 22 is positioned to extend downward from the edge located at the rear end of the extension portion 44.

[0030] The top panel 23 and the side panels 20 are connected to each other via connecting members 50, with each of the edges located in the left-right direction on the top surface 40 and each of the flange portions 26 being connected. The connecting members 50 connect each of the edges located in the left-right direction on the top surface 40 and each of the flange portions 26. As a result, each of the side panels 20 is positioned extending downward from each of the left and right edges on the top surface 40.

[0031] The connecting member 50 comprises an elongated portion 52 having a length approximately the same as the length of the side located at the upper end of the side plate 20, and a covering flat portion 54 extending downward from the rear end of the elongated portion 52. The covering flat portion 54 forms a plane perpendicular to the left-right direction.

[0032] Each of the side panels 20, when connected to the top surface 40, extends behind the rear end of the top surface 40 in the front-to-back direction, and together with the covering flat surface 54, covers the rear end of the extension 44 from both sides in the left-to-right direction. As a result, in the outer box 12, a machine room recess 5 is provided at the corner formed by the top and back surfaces, recessing toward the inner box 13. The space inside the outer box recess 3 is surrounded by the upright portion 32, the extended portion 34, and the covering flat portion 54, and functions as a machine room where various pieces of equipment constituting the refrigeration unit, such as a compressor, are housed. As shown in Figure 1, the machine room recess 5 is covered by a cover member 49.

[0033] Figure 3 is a perspective view of the insulated box 10. For the sake of explanation, Figure 3 shows the insulated box 10 cut by a plane perpendicular to the front-rear direction and passing between the storage hole 45 and the front end of the top panel 23 in a plan view of the top panel 23. For the sake of explanation, Figure 3 omits the control unit 46 and the cover member 49. As shown in Figure 3, in the process of forming the insulated box 10, when the inner box 13 is placed inside the outer box 12, a gap is created between the outer box 12 and the inner box 13. In the insulated box 10, foamed insulation material 11 injected from the injection hole 27 fills this gap.

[0034] Figure 4 is an exploded perspective view of the insulated box 10. Figure 5 is a plan view of the side panel 20. In Figure 4, for the sake of explanation, the control unit 46 and the cover member 49 are omitted. In Figure 5, for the sake of explanation, the non-storage section 76 is shown with a dashed line. As shown in Figures 4 and 5, a vacuum insulation material 60 is attached to each of the side panels 20. The vacuum insulation material 60 is an insulating member formed into a flat plate shape. The vacuum insulation material 60 comprises a first surface 61 which is a flat surface, and a second surface 63 which is a flat surface located on the opposite side of the first surface 61.

[0035] The vacuum insulation material 60 is formed such that its length in the front-to-back direction is less than or equal to the length of the side portion 28 in the front-to-back direction, and its length in the up-to-down direction is less than or equal to the length of the side portion 28 in the up-to-down direction. The vacuum insulation material 60 is attached to the side panel 20 with its first surface 61 in contact with the inner surface 28B. As a result, the vacuum insulation material 60 is positioned so that its first surface 61 faces the side panel 20 and its second surface 63 faces the inner box 13.

[0036] In this embodiment, when the vacuum insulation material 60 is attached to the side portion 28, it is surrounded by flange portions 24 and 25 from both the left and right sides, with its upper end positioned below the upper end of the side portion 28 and its lower end positioned above the lower end of the side portion 28.

[0037] Figure 6 shows a schematic cross-section of the vacuum insulation material 60. Figure 6 shows a cross-section in a plane perpendicular to the first surface 61 of the vacuum insulation material 60 and intersecting the gas adsorbent 72. As shown in Figure 6, the vacuum insulation material 60 comprises a core material 70, a gas adsorbent 72, and an outer covering material 74 that covers the core material 70 and the gas adsorbent 72.

[0038] The outer covering material 74 plays a role in maintaining the vacuum level, and may be made by laminating, for example, an innermost heat-sealable film, an intermediate gas barrier film, and an outermost surface protection film.

[0039] For the heat-sealable film, thermoplastic resins such as low-density polyethylene film, linear low-density polyethylene film, high-density polyethylene film, polypropylene film, polyacrylonitrile film, ethylene-vinyl alcohol copolymer film, or mixtures thereof may be used. For example, the gas barrier film may be made of metal foil such as aluminum foil or copper foil, or a film on which metals such as aluminum or copper or metal oxides have been deposited onto a substrate such as polyethylene terephthalate film, ethylene-vinyl alcohol copolymer film, or polyvinyl alcohol film. For the surface protective film, conventionally known materials such as nylon film, polyethylene terephthalate film, and polypropylene film may be used.

[0040] The gas adsorbent 72 can be, for example, a chemical adsorbent such as calcium oxide or magnesium oxide, a physical adsorbent such as zeolite, a mixture thereof, or a gas adsorbent alloy such as BaLi4. Alternatively, copper ion exchange ZSM-5 type zeolite, which has high gas adsorption capacity and adsorption ability, may be used. Depending on the application of the vacuum insulation material 60, the gas adsorbent 72 may be omitted, or it may be sealed within the outer covering material 74 together with a moisture absorbent.

[0041] The core material 70 is not specifically designated, but it should be a material that can maintain its thickness against atmospheric pressure when sealed under reduced pressure, has a high porosity, and low solid thermal conductivity. The material used for the core material 70 is preferably an inorganic powder aggregate, particularly silica powder, or an inorganic fiber aggregate, particularly glass fiber aggregate. Alternatively, for example, a composite core material formed by combining multiple materials may be used for the core material 70.

[0042] When forming the vacuum insulation material 60, the material forming the outer covering material 74 is folded, and one end of the material is heat-sealed to form a bag shape. After this, the core material 70 and the gas adsorbent 72 are placed inside the bag-shaped outer covering material 74, and the other end is heat-sealed to seal the core material 70 and the gas adsorbent 72 inside the outer covering material 74. As a result, a non-storage portion 76 is formed at the end of the outer covering material 74 where heat welding has been performed. The non-storage portion 76 is a portion of the outer covering material 74 where the core material 70 and the gas adsorbent 72 are not present. The non-storage portion 76 is located at the end of the vacuum insulation material 60 and is formed in a fin-like shape that extends continuously from the first surface 61 and the second surface 63, respectively.

[0043] As shown in Figure 5, in the vacuum insulation material 60, the non-storage portion 76 is folded back almost entirely and fixed in surface contact with the second surface 63. This prevents a gap from forming between the first surface 61 and the inner surface 28B when the vacuum insulation material 60 is attached to the side plate 20 in the storage compartment 1.

[0044] Figure 7 is a cross-sectional view of the cross-section in plane VII of Figure 1, viewed from below. Plane VII is the plane that intersects the side panel 20 and the vacuum insulation material 60. For the sake of explanation, the door 16 is omitted in Figure 7. As shown in Figures 3 to 7, the vacuum insulation material 60 is provided with a reinforcing portion 65. The reinforcing portion 65 is provided on the second surface 63 and is formed in a concave shape, or in other words, a groove shape, that slopes inward from the second surface 63 toward the first surface 61. As shown in Figure 7, the addition of the reinforcing portion 65 creates a parallel surface portion 66 formed substantially parallel to the side portion 28 on the vacuum insulation material 60, and an upright surface portion 68 rising from both ends of the parallel surface portion 66 toward the inner box 13. The upright surface portion 68 is a plane that intersects with the side portion 28.

[0045] The reinforcing portion 65 is formed on the second surface 63 to extend for a predetermined length along a direction perpendicular to the longitudinal direction of the vacuum insulation material 60. As shown in Figure 5, in this embodiment, the reinforcing portion 65 extends in the vertical direction, and two are provided from the upper end to the lower end of the vacuum insulation material 60. Each of the reinforcing portions 65 is arranged side by side in the front-to-back direction with a predetermined distance between them, and is also positioned at a specified distance from each of the flange portions 24 and 25. The vacuum insulation material 60 may be provided with one or more reinforcing parts 65. Furthermore, the reinforcing parts 65 may be positioned to overlap the non-storage section 76.

[0046] [1-2. Assembly process of the storage facility] When the storage compartment 1 is formed, first, a vacuum insulation material 60 is attached to each of the side panels 20. After this, the pair of side panels 20 that form each side of the outer box 12, the bottom panel 21, the back panel 22, and the top panel 23 are connected to each other. As described above, the vacuum insulation material 60 and the side panels 20 are long members that extend in the vertical direction. Therefore, when they are attached to each of the vacuum insulation material 60 and side panels 20, there is a risk that they may bend in a direction that intersects the longitudinal direction. Similarly, when each of the side panels 20 is connected to other members, there is a risk that they may bend in a direction that intersects the longitudinal direction.

[0047] In this embodiment, the vacuum insulation material 60 attached to the side panel 20 is provided with a reinforcing portion 65 that extends along the longitudinal direction of the side panel 20, thereby providing an upright surface portion 68 that intersects with the side portion 28. As a result, the vacuum insulation material 60 is reinforced, and the side panel 20 is also reinforced by the three-dimensional structure provided on the vacuum insulation material 60. Therefore, in the storage unit 1, bending of the vacuum insulation material 60 and the side panel 20 is suppressed during the assembly process of the storage unit 1.

[0048] When the pair of side panels 20, the bottom panel 21, the back panel 22, and the top panel 23 are connected to each other to form the outer box 12, the inner box 13 is placed inside the outer box 12. After this, foamed insulation material 11 is foamed and filled between the outer box 12 and the inner box 13, and the insulated box body 10 is formed by self-adhesion between the outer box 12 and the inner box 13. Since the reinforcing part 65 is provided on the second surface 63 facing the inner box 13, the space inside the reinforcing part 65 is continuous with the space between the outer box 12 and the inner box 13. For this reason, foamed insulation material 11 is foamed and filled inside the reinforcing part 65. As a result, even if the reinforcing section 65 is provided in the storage unit 1, the formation of a gap between the inner box 13 and the outer box 12 is suppressed.

[0049] The storage compartment 1 is formed by attaching doors 16, 17, and 18 to the insulated box body 10 formed as described above.

[0050] [1-3. Effects, etc.] As described above, in this embodiment, the storage unit 1 comprises an inner box 13 in which a storage chamber 15 is provided, and an outer box 12 in which the inner box 13 is housed. The outer box 12 is equipped with a vacuum insulation material 60 attached to at least one surface facing the inner box 13, and the surface of the vacuum insulation material 60 facing the inner box 13 is provided with a reinforcing portion 65 that extends along the longitudinal direction of the surface of the outer box 12 and is recessed toward the outer box 12.

[0051] As a result, the vacuum insulation material 60 and the side panels 20 are reinforced by the reinforcing portion 65, which is a three-dimensional structure provided in the vacuum insulation material 60. Therefore, in the storage facility 1, bending of the vacuum insulation material 60 and the side panels 20 is suppressed during the assembly process of the storage facility 1.

[0052] As in this embodiment, foam insulation material 11 may be filled between the outer box 12 and the inner box 13. As a result, even with the reinforcement section 65 provided in the storage unit 1, the formation of a gap between the inner box 13 and the outer box 12 is suppressed. Therefore, in the storage unit 1, the side panel 20 can be reinforced while suppressing a decrease in thermal insulation performance.

[0053] As in this embodiment, the vacuum insulation material 60 comprises a core material 70 and an outer covering material 74 that covers the core material 70. The outer covering material 74 has a non-storage portion 76 at its end where the core material 70 is not placed, and the non-storage portion 76 may be folded and positioned towards the inner box 13. As a result, in the storage compartment 1, when the vacuum insulation material 60 is attached to the side panel 20, the formation of a gap between the first surface 61 and the inner surface 28B is suppressed. In addition, the non-storage section 76 is positioned facing the space between the outer box 12 and the inner box 13. Therefore, in the storage compartment 1, even if the non-storage section 76 is folded and positioned, the formation of a gap between the vacuum insulation material 60 and other components is suppressed.

[0054] (Other embodiments) As described above, Embodiment 1 has been explained as an example of the technology disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to create new embodiments by combining the components described in Embodiments 1 and 2 above. Therefore, other embodiments are illustrated below.

[0055] In the embodiment described above, the reinforcing portion 65 extends along the vertical direction of the side plate 20 and is provided from the upper end to the lower end of the vacuum insulation material 60. However, it is not limited to this, and the reinforcing portion 65 may be formed in any way as long as it extends for a predetermined length along a direction that intersects the direction perpendicular to the longitudinal direction of the side plate 20. For example, the reinforcing portion 65 may be formed to extend along at least one of the diagonals of the side portion 28.

[0056] For example, the reinforcing portion 65 may extend along the vertical direction of the side plate 20 and be provided intermittently from the upper end to the lower end of the vacuum insulation material 60. That is, the reinforcing portion 65 may be formed in the shape of a dashed line extending along the vertical direction. For example, the reinforcing portion 65 may be provided at any location on the side plate 20 in the vertical direction, such as approximately in the center.

[0057] In the embodiment described above, the reinforcing portion 65 is provided on the vacuum insulation material 60 attached to the side panel 20. However, the vacuum insulation material 60 is not limited to this, and may be attached to any member forming one of the surfaces of the outer box 12, such as the bottom panel 21, the back panel 22, or the top panel 23, and the reinforcing portion 65 may be provided on the vacuum insulation material.

[0058] Furthermore, for example, a predetermined structure may be provided on the first surface 61 of the vacuum insulation material 60. For example, the first surface 61 of the vacuum insulation material 60 may be provided with a groove that is recessed from the first surface 61 toward the second surface 63, and a heat dissipation pipe may be provided in the groove. For example, the first surface 61 of the vacuum insulation material 60 may not have grooves that extend from the first surface 61 toward the second surface 63, and the heat dissipation pipe may not be provided.

[0059] In the above-described embodiment, the outer box 12 may be made of a hard resin such as ABS resin, not just metal. Furthermore, the outer box 12 and the inner box 13 may be made of a combination of metal and hard resin. Alternatively, for example, the insulated box 10 may be formed by combining insulated walls, which are created by forming a housing-like structure from plate-shaped members such as steel plates and filling the inside of the housing with foamed insulation material 11. In this case, the vacuum insulation material 60 is arranged so that its first surface 61 is in contact with the plane of the plate-shaped member.

[0060] The embodiments described above are for illustrative purposes only and may be modified, replaced, added, or omitted within the scope of the claims or equivalents thereof.

[0061] (Note) Based on the above description of embodiments, the following technologies are disclosed.

[0062] (Technical 1) A storage container comprising an inner box having a storage chamber inside, and an outer box in which the inner box is housed, wherein the outer box is provided with a vacuum insulating material attached to at least one surface facing the inner box, and the surface of the vacuum insulating material facing the inner box is provided with a reinforcing portion that extends along the longitudinal direction of the surface of the outer box and is recessed toward the outer box. As a result, the vacuum insulation material is reinforced by the reinforcement section. Therefore, in storage facilities, bending of the vacuum insulation material is suppressed during the assembly process of the storage facility.

[0063] (Technology 2) The storage container according to Technology 1, wherein foam insulation material is filled between the outer box and the inner box. This prevents the formation of a gap between the inner and outer boxes in the storage facility, even if reinforcement is provided. Therefore, the vacuum insulation material can be reinforced in the storage facility while suppressing a decrease in thermal insulation performance.

[0064] (Technical 3) The storage container according to Technical 1 or Technical 2, wherein the vacuum insulation material comprises a core material and an outer covering material that covers the core material, and a non-storage portion is provided at the end of the outer covering material in which the core material is not placed, and the non-storage portion is folded and arranged toward the inner box side. This prevents gaps from forming between the vacuum insulation material and the outer box when the vacuum insulation material is attached to the outer box in a storage facility. Therefore, even if the non-storage section is folded and positioned in the storage facility, the deterioration of insulation performance is suppressed, while preventing gaps from forming between the vacuum insulation material and other components. [Industrial applicability]

[0065] As described above, the storage container according to this disclosure can be suitably used in refrigerators and the like, which can suppress the bending of any of the members forming a surface during the assembly process. [Explanation of Symbols]
