[Effects of the Invention]

[0007] According to this disclosure, a sealing member can be appropriately provided. This makes it possible to provide a storage container that enhances cooling efficiency. [Brief explanation of the drawing]

[0008] [Figure 1] Perspective view of a storage facility according to an embodiment of this disclosure [Figure 2] Perspective view of an insulated door [Figure 3] Exploded perspective view of an insulated door [Figure 4] Cross-sectional view taken along plane IV in Figure 1 [Figure 5] Plan view of the sealing member and the mounting guide member. [Modes for carrying out the invention]

[0009] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived of this disclosure, there was a storage unit in which sealing members that could be tightly fitted together were attached to the opposing sides of each of a pair of double-hinged insulated doors via mounting guide members. In this storage unit, the sealing members are joined by sliding and inserting them into grooves provided in the mounting guide members. Therefore, in the case of maintenance, these packings and cover members can be easily attached and detached by sliding them in the vertical direction relative to each other.

[0010] However, in conventional storage facilities, there is a risk that the mounting guide member may be installed with a misaligned mounting position in the thickness direction of the insulated door. The inventors discovered that if the mounting guide member is installed with a misaligned mounting position, there is a risk that the mounting position of the sealing member attached to the mounting guide member may also be misaligned. To solve this problem, the subject matter of this disclosure was established. Therefore, this disclosure provides a storage container on which a sealing member can be easily installed.

[0011] 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.

[0012] (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 4. In each figure, the symbol FR indicates the front of the storage unit 1 in its installed state, the symbol UP indicates the area above the storage unit 1, and the symbol LH indicates the area to the left of the storage unit 1. In the following description, each direction is a direction along these directions of the storage unit 1.

[0013] [1-1. Structure] [1-1-1. Storage Room Configuration] Figure 1 is a front view of a storage unit 1 according to an embodiment of the present invention. Storage unit 1 is a vertical refrigerator, as shown in Figure 1. Storage unit 1 comprises a storage unit body 2, multiple insulated doors 4, and a machine room 6.

[0014] The storage unit body 2 comprises an outer box 5 that opens to the front, an inner box 7 housed inside the outer box 5 and also opening to the front, and an insulating material 8 provided in the space between the outer box 5 and the inner box 7 (Figure 4). The storage body 2 is a box body provided with a heat insulating wall formed by filling a heat insulating material 8 into a space surrounded by an outer box 5 and an inner box 7 (Fig. 4). In the present embodiment, both the outer box 5 and the inner box 7 are integrally formed of a metal such as a stainless steel plate. For the heat insulating material 8, styrofoam, rigid urethane foam or the like is used. The storage body 2 is provided with a storage chamber 2A inside, and a rectangular opening 2B in a front view is provided on a front surface thereof.

[0015] It should be noted that the outer box 5 and the inner box 7 are not limited to metal, and may be formed of a hard resin such as ABS resin. Further, the outer box 5 and the inner box 7 may be formed by combining metal and hard resin. Further, for example, the storage body 2 may be formed by forming a plate-shaped member such as a steel plate into a housing shape, and combining a heat insulating wall formed by filling the inside of the housing with the heat insulating material 8.

[0016] The machine room 6 is disposed above the storage body 2. A refrigeration device 61 constituting a refrigeration cycle is housed inside the machine room 6. More specifically, the refrigeration device 61 includes a compressor 62, a condenser 63, a condenser blower 64, a capillary tube 65, and an electrical box 66. When these components are driven, cold air is fed into the storage chamber 2A. It should be noted that the capillary tube 65 may be another throttling mechanism such as a throttle valve.

[0017] The plurality of heat insulating doors 4 are rectangular door members that openably and closably close the opening 2B of the storage body 2. The storage 1 of the present embodiment is provided with two sets of upper and lower pairs, where one pair is a pair of heat insulating doors 4 arranged in the left-right direction. These heat insulating doors 4 are arranged with one side surface adjacent to each other. Hinges 11 are provided on the upper surface and the lower surface of each heat insulating door 4 at positions located on the other side surface side of each heat insulating door 4. Each of the pair of heat insulating doors 4 can be opened and closed in the left-right direction of the storage 1 by these hinges 11. That is, the pair of heat insulating doors 4 are so-called double-opening doors. In the present embodiment, the pair of heat insulating doors 4 are so-called double-leaf swing doors formed symmetrically. On the front face of each heat-insulating door 4, a handle 18 is provided on the side surface side adjacent to each other in the left-right direction. The heat-insulating door 4 corresponds to the "door" in the present disclosure.

[0018] Fig. 2 is a perspective view of the heat-insulating door 4. Fig. 2 is a view of the heat-insulating door 4 viewed from the rear face 4A side. One heat-insulating door 4 will be described below, and the other heat-insulating doors 4 also have the same structure. As shown in Fig. 2, the heat-insulating door 4 is a plate-shaped member having a predetermined thickness. The heat-insulating door 4 includes a heat-insulating door main body 12 and a plurality of outer edge sealing members 50.

[0019] The front face, both side faces, top face, bottom face of the heat-insulating door main body 12 and the outer edge of the rear face are all formed by a door exterior plate 13 integrally formed of metal such as a stainless steel plate. The central portion of the rear face of the heat-insulating door main body 12 is configured by a door interior plate 14 formed of hard resin. The central portion of the door interior plate 14 protrudes toward the inner side of the storage compartment 2A beyond the outer edge of the rear face of the heat-insulating door main body 12. That is, in the heat-insulating door 4, the rear face 4A, which is the face facing the storage main body 2, has a central portion formed by the door interior plate 14, and an outer edge along each side formed by the door exterior plate 13. The rear face 4A of the heat-insulating door 4 corresponds to the "main body opposing face" in the present disclosure.

[0020] As shown in Fig. 2, the space surrounded by the door exterior plate 13 and the door interior plate 14 is filled with a heat insulating material 8 such as expanded polystyrene or rigid urethane foam. Note that the door exterior plate 13 is not limited to metal, and may be formed of hard resin such as ABS resin.

[0021] Next, the rear face of the heat-insulating door main body 12 will be described. The outer edge of the rear face of the heat-insulating door main body 12 has the top side, the bottom side and each side face side formed by the end portion of the door exterior plate 13, and the central side of the rear face formed by the end portion of the door interior plate 14. An outer edge mounting groove 53 is provided around the entire circumference of the end of the door interior panel 14, that is, the outer edge of the rear surface of the insulated door body 12 (Figure 4). This outer edge mounting groove 53 opens towards the door interior panel 14 and has a groove shape that protrudes toward the door exterior panel 13. In a cross-sectional view in the width direction, the width dimension of this outer edge mounting groove 53 is narrow near the opening and wider at the front side of the insulated door body 12. In other words, in a cross-sectional view perpendicular to the longitudinal direction of the outer edge mounting groove 53, it is formed in a so-called dovetail groove shape (Figure 4).

[0022] An outer edge sealing member 50 is attached to the outer edge mounting groove 53. The outer edge sealing member 50 is a sealing member such as a packing or gasket, made of a soft resin such as rubber or soft polyvinyl chloride. The outer edge sealing member 50 is integrally molded into a rectangular frame shape. Alternatively, the outer edge sealing member 50 may be formed in four straight lines, each attached to the outer edge mounting groove 53, thereby arranging in a frame shape on the insulated door body 12.

[0023] The outer edge sealing member 50 comprises a bag-shaped sealing member body 56 formed in a hollow shape with a space inside. On the front side of the outer edge sealing member 50 within this space, an outer edge magnet housing section 51 with a rectangular cross-section is provided along the entire circumferential direction (Figure 4). Furthermore, four rod-shaped outer edge magnets 52 are housed in this outer edge magnet housing section 51 (Figure 4). Each outer edge magnet 52 has a length approximately equal to each side of the rear surface 4A of the insulated door 4. Each outer edge magnet 52 is inserted into the outer edge magnet housing section 51 along each side of the outer edge sealing member 50.

[0024] Next, we will describe the structure of side 4B of the insulated door 4. Figure 3 is an exploded perspective view showing the insulated door 4, the mounting guide member 24, and the sealing member 26. In Figure 3, dots are added to the side packing 28 and the fin member 32, which are made of a soft material, for the sake of explanation. The following describes the side 4B of one of the insulated doors 4, but the other insulated door 4 has a similar structure. As shown in Figure 3, a sealing member 26 is provided on the side surface 4B of each insulated door 4 adjacent to the other insulated door 4 via a mounting guide member 24. The side surface 4B of the insulated door 4 corresponds to the "opposing surface" in this disclosure.

[0025] The mounting guide member 24 is formed from a rigid resin as a rigid material. This mounting guide member 24 has a length approximately the same as the side surface 4B of the insulated door 4 and is a rail-shaped member formed, for example by extrusion molding, so that its cross-section is C-shaped. The mounting guide member 24 is installed so that its vertical direction is aligned with the vertical direction of the insulated door 4. The width dimension of this mounting guide member 24 is formed to be approximately the same as the width dimension of the side surface 4B of the insulated door 4. The mounting guide member 24 is fixed to the side surface 4B of the insulated door 4 by being screwed in at several points on its bottom surface 24A. For this reason, multiple screw holes 12A are provided on the side surface 4B of the insulated door 4. Multiple screw holes are provided on the bottom surface 24A of the mounting guide member 24.

[0026] Figure 4 is a cross-sectional view of the storage room 1 cut along plane IV in Figure 1. Plane IV is a plane perpendicular to the side surfaces 4B of each of the pair of insulated doors 4 arranged in the left-right direction. Figure 4 shows a cross-section of the storage room 1 cut along plane IV, including each of the adjacent side surfaces of the pair of insulated doors 4. In Figure 4, dots are added to the insulation material 8 for ease of explanation. Figure 5 is a plan view of the sealing member 26 and the mounting guide member 24. In Figure 5, the sealing member 26 and the mounting guide member 24 are shown in a disassembled state, with their respective end faces indicated. For ease of explanation, the sealing member 26 is shown with hatching in Figure 5.

[0027] A groove-shaped packing guide groove 24C is provided on the storage unit body 2 side of the mounting guide member 24, extending over the entire vertical direction of the mounting guide member 24. As shown in Figures 4 and 5, the packing guide groove 24C is provided projecting from the bottom surface 24A toward the side surface 4B of the other insulated door 4. A portion of the packing guide groove 24C located on the storage unit body 2 side is open. The insertion portion 28F1 of the side packing 28, which will be described later, is inserted through the packing guide groove 24C.

[0028] In the packing guide groove 24C, a first heater holding portion 24D for holding the heater 36 (described later) is provided on the front side of the insulated door 4. This first heater holding portion 24D is formed in a groove shape with an open section on the other side of the insulated door 4.

[0029] A retaining member engaging piece 24E is provided on the front side of the insulated door 4 of the first heater retaining member 24D. This retaining member engaging piece 24E is formed in a claw shape that protrudes to the front side of the insulated door 4. A cover member engaging piece 30B provided by the cover member 30, which will be described later, engages with this retaining member engaging piece 24E.

[0030] In the packing guide groove 24C, a second heater holding portion 24G capable of holding a heater 36 (described later) is provided on the rear surface 4A side of the insulated door 4. The second heater holding portion 24G is formed in a groove shape with an open section on the other side of the insulated door 4. The second heater holding portion 24G is positioned closer to the storage chamber 2A than the first heater holding portion 24D and the side surface of the insulated door body 12.

[0031] In the second heater holding section 24G, a housing section restricting section 24H is provided on the rear surface 4A side of the insulated door 4. The housing section restricting section 24H has a plane facing the side surface 4B of the other insulated door 4. When the sealing member 26 is attached to the mounting guide member 24, the housing section restricting section 24H is positioned at a predetermined distance along the left-right direction from the side magnet housing section 28A of the side packing 28. The housing section restricting section 24H prevents the side magnet housing section 28A from deforming toward the side surface 4B of the insulated door 4 located to the right.

[0032] A locking portion 24F is provided on the front side of the mounting guide member 24 facing the insulated door 4. Similar to the packing guide groove 24C, this locking portion 24F is provided projecting from the bottom surface 24A toward the side surface 4B of the other insulated door 4. The tip of the locking portion 24F is curved in a claw shape. This locking portion 24F is inserted into a locking groove 30C provided by the cover member 30, which will be described later.

[0033] The mounting guide member 24 is provided with a contact portion 70. The contact portion 70 extends from the rear end of the mounting guide member 24 and contacts the rear surface 4A of the insulated door 4 to which the mounting guide member 24 is attached. That is, when the mounting guide member 24 is attached to the insulated door 4, it contacts the side surface 4B and the rear surface 4A of the insulated door 4. In this embodiment, the contact portion 70 extends from one side 4B of the insulated door 4 along the rear surface 4A of the insulated door 4 with respect to the packing guide groove 24C.

[0034] As shown in Figure 4, an outer edge sealing member 50 is attached to the outer edge of the rear surface of the insulated door body 12. The outer edge sealing member 50 comprises a sealing member body 56 and a fin portion 58 extending from the surface of the sealing member body 56. The fin portion 58 extends from the surface of the sealing member body 56 located on the mounting guide member 24 side toward the mounting guide member 24, and its tip abuts against the rear surface of the insulated door body 12, i.e., the rear surface 4A of the insulated door 4. The contact portion 70 is positioned spaced apart from the fin portion 58 in the left-right direction.

[0035] The contact portion 70 is provided with a rib-shaped projection 71 that extends toward the outer edge sealing member 50. The tip of the projection 71 is positioned between the sealing member body 56 and the fin portion 58. In other words, in the storage unit 1, the sealing member body 56, the projection 71, and the fin portion 58 are arranged in order from the storage chamber 2A side toward the outside of the storage unit 1.

[0036] As a result, a so-called labyrinth structure is formed in storage 1, extending from the storage chamber 2A side toward the outside of storage 1. Therefore, in storage 1, air from storage chamber 2A leaking out to the outside of storage 1 and air from outside storage 1 entering storage chamber 2A are suppressed. Furthermore, changes in the temperature of storage chamber 2A are suppressed in storage 1.

[0037] The contact portion 70 is provided with an extension portion 72 that extends toward the storage chamber 2A. The extension portion 72 is positioned in the front-rear direction of the storage chamber 1 to be closer to the insulated door 4 than the side of the outer edge sealing member 50 that is located toward the storage chamber 2A. A flat portion 74 is provided at the tip of the extension portion 72. The flat portion 74 forms a plane that is substantially parallel to and opposite the opening 2B.

[0038] As a result, the mounting guide member 24 is provided with a plane that closes off a portion of the opening 2B. Therefore, in the storage unit 1, the mounting guide member 24 prevents air from the storage chamber 2A from leaking out of the storage unit 1 and prevents air from outside the storage unit 1 from entering the storage chamber 2A.

[0039] The flat portion 74 is positioned at a predetermined distance from the outer edge sealing member 50 in the left-right direction. This prevents the flat portion 74 from hindering the deformation of the outer edge sealing member 50, even when the outer edge sealing member 50 deforms in close contact with the storage container body 2 in the storage container 1.

[0040] In the contact portion 70, a third heater holding portion 78 is provided at a position closer to the other insulated door 4 than the extension portion 72. The third heater holding portion 78 is formed in a groove shape with an open portion on the side facing the other insulated door 4. The third heater holding portion 78 is capable of holding the heater 36, which will be described later. The third heater holding portion 78 is positioned closer to the storage chamber 2A than the first heater holding portion 24D and the side surface 4B of the insulated door 4. The third heater holding portion 78 is positioned closer to the outer edge sealing member 50 than the second heater holding portion 24G.

[0041] The flat portion 74 is provided with rib-shaped restricting pieces 76 that protrude toward the insulated door 4 on which the flat portion 74 is provided. The tip of the restricting piece 76 is positioned at a predetermined distance from the third heater holding portion 78. In the storage compartment 1, when the open insulated door 4 is closed, the flat portion 74 may come into contact with the storage compartment body 2 or the partition member separating the opening 2B. In this case, the restricting piece 76 comes into contact with the third heater holding portion 78, which prevents the extended portion 72 from bending and breaking. The second heater holding portion 24G and the third heater holding portion 78 correspond to the "heater holding portion" in this disclosure.

[0042] Next, the sealing member 26 will be described. As shown in Figures 3 and 5, the sealing member 26 comprises a side packing 28, a cover member 30, and a fin member 32, which are formed by integrally molding them. This sealing member 26 is a rail-shaped member with a length similar to that of the mounting guide member 24 and a C-shaped cross-section, and the sealing member 26 is installed so that its vertical direction is aligned with the vertical direction of the insulated door 4.

[0043] The side packing 28 forms the portion of the sealing member 26 that is located on the storage body 2 side. The side packing 28 is made of a soft resin such as rubber or soft polyvinyl chloride. The side packing 28 is molded to have an L-shape in cross-section, and a side magnet housing portion 28A is provided at the corner of the L-shape, which is partitioned to form a rectangular space in cross-section. A rod-shaped side magnet 34 is inserted through this side magnet housing 28A. The side packing 28 corresponds to the “packing” in this disclosure.

[0044] As shown in Figure 3, both ends of the side magnet housing 28A are closed by retaining members 35. The retaining members 35 are plate-shaped members formed by bending them so that their cross-section is L-shaped. These retaining members 35 are inserted into the upper and lower ends of the side magnet housing 28A and are attached to the side packing 28. This prevents the side magnets 34 from falling out of the side packing 28.

[0045] A first sealing portion 28B is provided on the storage body 2 side of the side magnet housing portion 28A. As shown in Figure 4, this first sealing portion 28B extends toward the outer edge sealing member 50. A second sealing portion 28C is provided at the tip of the first sealing portion 28B. This second sealing portion 28C protrudes toward the storage body 2 side and then bends and extends toward the other insulated door 4 side. That is, in the insulated door 4 located on the right, the first sealing portion 28B and the second sealing portion 28C are formed to have a C-shaped cross-section, as shown in Figure 5. In the insulated door 4 located on the left, the first sealing portion 28B and the second sealing portion 28C are formed to have an inverted C-shaped cross-section.

[0046] The tip portion 28C1 of the second sealing portion 28C extends to a position in the side magnet housing portion 28A that is approximately the same as the surface located on the other side of the insulated door 4. The vertical length of this second sealing portion 28C is shorter than the vertical length of the side packing 28 and is about the same length as the vertical length of the door interior panel 14.

[0047] As shown in Figures 4 and 5, a fin portion 28D is provided on the outer edge sealing member 50 side of the first seal portion 28B. This fin portion 28D extends toward the outer edge sealing member 50, and its tip can abut against the outer edge sealing member 50.

[0048] A connecting portion 28E is provided on the front side of the insulated door 4 of the side magnet housing portion 28A. This connecting portion 28E is formed in a fin shape that extends to the front side of the insulated door 4. The tip of the connecting portion 28E is connected to the bottom surface 30A of the cover member 30.

[0049] An extension portion 28F is provided on the side 4B side of the insulated door 4 of the side magnet housing portion 28A. This extension portion 28F extends from the side 4B side of the insulated door 4 of the side magnet housing portion 28A toward the side 4B of the insulated door 4, and then extends toward the front surface of the insulated door 4. That is, the extension portion 28F is formed in a substantially L-shape in cross-section. An insertion portion 28F1, formed in a T-shape in cross-section, is provided at the tip of the extension portion 28F. As described above, this insertion portion 28F1 is inserted into the packing guide groove 24C provided in the mounting guide member 24.

[0050] Next, the cover member 30 will be described. As shown in Figures 3 and 5, the cover member 30 is formed from a hard resin as a rigid material. As shown in Figure 4, the cover member 30 has a C-shaped cross-section. As described above, the connecting portion 28E of the side packing 28 is attached to the end of the bottom surface 30A of the cover member 30 that is located on the storage body 2 side. As shown in Figures 4 and 5, a cover member engaging piece 30B is provided at the end of the bottom surface 30A of the cover member 30 that is located on the storage body 2 side. This cover member engaging piece 30B protrudes from the bottom surface 30A toward the side surface 4B of the insulated door 4. The tip of the cover member engaging piece 30B is formed in a claw shape. As described above, the cover member engaging piece 30B engages with the retaining part engaging piece 24E. Furthermore, a rib 30B1 is provided on the cover member engaging piece 30B. The rib 30B1 protrudes from the bottom surface 30A toward the storage body 2. The rib 30B1 closes the open portion of the first heater holding part 24D in which the heater 36 is held.

[0051] A locking groove 30C is provided at the end of the bottom surface 30A of the cover member 30 that is located on the front side of the insulated door 4. This end with the locking groove 30C protrudes from the bottom surface 30A toward the side surface 4B of the insulated door 4. The locking groove 30C has a groove shape that is open at the end located toward the side surface 4B of the insulated door 4. As described above, the locking portion 24F is inserted through the locking groove 30C.

[0052] A fin member 32 is integrally provided at the tip of the locking groove 30C located on the front side of the insulated door 4. This fin member 32, like the side packing 28, is made of a soft material such as rubber or other soft resin. The fin member 32 extends toward the side 4B of the insulated door 4. The tip of the fin member 32 abuts against the side 4B of the insulated door 4.

[0053] As shown in Figure 3, a linear heater 36 is sandwiched between the mounting guide member 24 and the sealing member 26. This heater 36 is a linear heating element that heats the sealing member 26 to suppress condensation and freezing. In this embodiment, the heater 36 is an electric heating wire that generates heat when power is supplied.

[0054] The heater 36 is arranged in a loop shape along the entire vertical length of the side surface 4B of the insulated door 4. The upper and lower ends of the heater 36 are fixed to the mounting guide member 24 by heater retaining pieces 37. The heater retaining pieces 37, together with the heater 36, are sandwiched between the mounting guide member 24 and the sealing member 26.

[0055] As shown in Figure 4, the heater 36 is sandwiched in the first heater holding portion 24D as described above, and the open portion of the first heater holding portion 24D is closed by the rib 30B1, thereby fixing it between the mounting guide member 24 and the sealing member 26. As a result, when the heater 36 generates heat on the side 4B of the insulated door 4, it heats, for example, the connecting portion 28E. Therefore, condensation and freezing are suppressed in the insulated door 4, for example, at the connecting portion 28E.

[0056] The heater 36 held by the first heater holder 24D can be further held by the second heater holder 24G or the third heater holder 78. When the heater 36 is held in the second heater holding portion 24G, it heats the packing space S3 surrounded by the extension portion 28F of the side packing 28, the side magnet housing portion 28A, the connecting portion 28E, the cover member 30, and the mounting guide member 24. When the heater 36 is held by the third heater holding portion 78, it heats the packing space S4 surrounded by the extended portion 28F of the side packing 28, the first sealing portion 28B, and the contact portion 70 of the mounting guide member 24.

[0057] In this way, the heater 36 selectively heats the side packing 28 at multiple locations. Therefore, the insulated door 4 can suppress condensation and freezing at predetermined locations on the side packing 28.

[0058] As shown in Figure 3, both the mounting guide member 24 and the sealing member 26 in the vertical direction are closed by the cap 38. As shown in Figure 3, the cap 38 is a flat plate member formed in an L-shape when viewed from above, and one end of the cap 38 extends along the shorter side of the side 4B of the insulated door 4. The other end of the cap 38 wraps around to the outer edge side of the rear surface 4A of the insulated door 4 and extends along the outer edge and the upper surface of the outer edge sealing member 50.

[0059] The back surface of the cap 38 is provided with a pair of insertion portions 38A that protrude downward. The insertion portions 38A are inserted into the space enclosed by the mounting guide member 24 and the sealing member 26. This prevents dust and dirt from entering between the mounting guide member 24 and the sealing member 26, and covers and protects the heater 36.

[0060] A screw hole 38C is provided at the tip of the other end of the cap 38, and a screw hole is provided on the outer edge of the rear surface 4A of the insulated door 4. The cap 38 is fixed to the insulated door 4 by screwing the screw hole 38C and the screw hole together with a screw 40.

[0061] [1-2. Operation] The operation of storage facility 1, configured as described above, will be explained below. First, we will explain the procedure for attaching the mounting guide member 24 to the insulated door body 12. The mounting guide member 24 has its bottom surface 24A in contact with the side surface 4B of the insulated door 4. In this state, the contact portion 70 is in contact with the rear surface 4A of the insulated door 4. This allows the mounting guide member 24 to be easily positioned in the front-rear direction of the insulated door 4. Therefore, the mounting guide member 24 can be easily attached to the side surface 4B of the insulated door 4 while suppressing misalignment. Next, the mounting guide member 24 is fixed to the side 4B of the insulated door 4 by being screwed in at several points on the bottom surface 24A.

[0062] Next, the procedure for attaching the sealing member 26 to the mounting guide member 24 will be described. First, the heater 36 is sandwiched in the heater holding groove 24E. Next, the sealing member 26 is fixed to the mounting guide member 24 by inserting one end of the sealing member 26 through one end of the mounting guide member 24 while sliding it in the vertical direction. As a result, the sealing member 26 is fixed to the mounting guide member 24 without the use of fixing members or tools. Therefore, it is possible to reduce the number of parts in the storage unit 1, and to make the manufacturing and maintenance of the refrigerator easier.

[0063] When the pair of insulated doors 4 of the storage unit 1 are closed, the outer edge magnets 52 are attracted to the storage unit body 2 by magnetic force, and the outer edge sealing member 50, specifically the side of the insulated door 4 on the hinge 11 side and the portion along the top and bottom surfaces of the insulated door 4, comes into close contact with the storage unit body 2. The side magnets 34 on each sealing member 26 of each insulated door 4 are attracted to each other by magnetic force. As a result, each extension portion 28F and connecting portion 28E extends toward the side 4B of the other insulated door 4. Then, the side surfaces 28A1 of each side magnet housing portion 28A located on the other insulated door 4 side come into close contact with each other, sealing the space between the sides 4B of each insulated door 4.

[0064] When the side surfaces 28A1 of the storage section are in close contact with each other, the tips 28C1 of each second sealing portion 28C come into contact with each other. This forms a sealing space S1 surrounded by each first sealing portion 28B and each second sealing portion 28C. The air in this sealing space S1 acts as an insulating air layer, suppressing heat from entering the storage chamber 2A through the gaps between the side packings 28, and also suppressing the leakage of cold air from inside the storage chamber 2A.

[0065] Furthermore, a sealing space S2 is formed on the side 4B of each insulated door 4, surrounded by a mounting guide member 24, an extension portion 28F, a first sealing portion 28B, a fin portion 28D, and an outer edge sealing member 50. The air within this sealing space S2 also acts as an insulating air layer. In addition, as described above, the fin member 32 abuts against the side surface 4B of the insulated door 4. These insulating air layers and the fin member 32 prevent heat from entering the storage chamber from between the side surface 4B of the insulated door 4 and the mounting guide member 24, and also prevent cold air from leaking out of the storage chamber 2A.

[0066] Thus, since the sealing member 26 is formed by integrally molding a side packing 28 made of soft resin and a cover member 30 made of hard resin, it is possible to seal the gap between the sides 4B of the insulated door 4 while giving the sealing member 26 a predetermined strength. It is also possible to suppress the accumulation of dust and dirt between the side packing 28 and the cover member 30. Furthermore, when performing maintenance or cleaning, the user does not need to individually remove the side packing 28 and the cover member 30, which helps to prevent damage to or detachment of these side packings 28 and cover member 30. In addition, there is no need to provide a structure or mechanism for connecting the side packing 28 and the cover member 30, which allows the sealing member 26 to be made smaller and the insulated door 4 to be made thinner and lighter.

[0067] As shown in Figure 4, in the sealing member 26, a flat portion 74 is positioned between the side magnet housing portion 28A and the outer edge sealing member 50 in the left-right direction. The flat portion 74 has a plane that intersects in the front-rear direction, in other words, in the direction from the storage chamber 2A toward the front side of the insulated door 4. The length dimension of the plane in the left-right direction is such that it does not come into contact with the side packing 28 and the outer edge sealing member 50 in either case when the pair of insulated doors 4 are opened or closed. As a result, the sealing member 26 can prevent heat from entering the storage chamber 2A and prevent cold air from leaking out of the storage chamber 2A without hindering the function of the side packing 28 and the outer edge sealing member 50.

[0068] In addition, the flat portion 74 is positioned close to the front surface of the first sealing portion 28B from the mounting guide member 24 side. As a result, even if the sealing member 26 deforms so that the side packing 28 moves closer to the front side, the flat portion 74 corrects it to a predetermined position. This suppresses deformation of the sealing member 26 and prevents misalignment.

[0069] As described above, the sealing member 26 is formed by integrally molding a side packing 28 made of soft resin and a cover member 30 made of hard resin. The side magnet housing portion 28A of the side packing 28 is corrected to a predetermined position by the housing portion regulating portion 24H. The first sealing portion 28B of the side packing 28 is corrected by the flat portion 74.

[0070] In this way, deformation and misalignment of the side packing 28, which is a soft component of the sealing member 26, are suppressed by the various parts of the mounting guide member 24. Therefore, in the storage unit 1, it is possible to reduce the frequency of maintenance and replacement of the sealing member 26, in which the side packing 28 and the cover member 30 are integrally molded.

[0071] In addition, the mounting guide member 24 is easily positioned by the contact portion 70 contacting the rear surface 4A of the insulated door 4. Therefore, in the storage room 1, positional displacement due to deformation or dimensional tolerances can be suppressed throughout the entire insulated door 4.

[0072] [1-3. Effects, etc.] As described above, in this embodiment, the storage unit 1 is formed by fixing mounting guide members 24 to each side 4B of a double-hinged insulated door 4 provided in the opening 2B of the storage unit body 2, and providing a packing-type sealing member 26 to each mounting guide member 24. The mounting guide member 24 has a contact portion 70 that abuts against the rear surface 4A, which is the side of the insulated door 4 that faces the storage unit body 2.

[0073] As a result, the mounting guide member 24 can be easily positioned in the front-to-back direction of the insulated door 4. Therefore, the mounting guide member 24 can be easily attached to the side surface 4B of the insulated door 4 while suppressing misalignment. Furthermore, in storage unit 1, variations between products due to manufacturing can be suppressed. As a result, in storage unit 1, the airtightness between the insulated door 4 and the storage unit body 2 is improved, and the cooling effect can be improved.

[0074] As in this embodiment, the contact portion 70 may be provided with a flat portion 74 that forms a plane facing the opening 2B. As a result, the mounting guide member 24 is provided with a plane that closes off a portion of the opening 2B. Therefore, in the storage unit 1, the mounting guide member 24 prevents air from the storage chamber 2A from leaking out of the storage unit 1 and prevents air from outside the storage unit 1 from entering the storage chamber 2A.

[0075] As in this embodiment, the contact portion 70 may be provided with a third heater holding portion 78 for holding a heater 36 for heating the sealing member 26, and a second heater holding portion 24G, at a position closer to the storage body 2 than the insulated door 4. As a result, the heater 36 heats a predetermined area of ​​the side packing 28. Therefore, the insulated door 4 can suppress condensation and freezing at the predetermined area of ​​the side packing 28.

[0076] The sealing member 26 is formed by integrally molding a side packing 28 and a cover member 30 that covers the mounting guide member 24. This makes it possible to seal the sides 4B of the insulated door 4 in the storage room 1 while giving the sealing member 26 a predetermined strength.

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.

[0078] In the embodiment described above, the storage compartment 1 is a four-door vertical refrigerator, but it is not limited to this, and may also be applied to refrigerators such as under-counter type refrigerators or household refrigerators equipped with multiple storage compartments formed by partitions or the like. For example, in the storage unit 1, not only the outer edge sealing member 50 but also the side packing 28 may be formed hollow and divided into multiple spaces.

[0079] For example, the storage unit 1 may be a single-door refrigerator. Even with such a refrigerator, the mounting guide member 24 can be easily positioned in the front-to-back direction of the insulated door 4. Therefore, the mounting guide member 24 can be easily attached to the side surface 4B of the insulated door 4 while suppressing misalignment. Furthermore, in storage unit 1, variations between products due to manufacturing can be suppressed. As a result, in storage unit 1, the airtightness between the insulated door 4 and the storage unit body 2 is improved, and the cooling effect can be improved.

[0080] In the embodiment described above, the contact portion 70 is provided with an extension portion 72, a flat portion 74, and a third heater holding portion 78, but these may be omitted. Also, for example, the second heater holding portion 24G may be omitted.

[0081] In the embodiment described above, a heater 36 was provided as a heat-generating element for heating the sealing member 26.
