[Diagram 5] FIG. 2 is a plan view of the sealing member and the mounting guide member; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the idea of ​​this disclosure, there was a storage cabinet in which sealing members capable of sealing with each other were attached to the opposing sides of a pair of double-opening insulated doors via an attachment guide member. In this storage cabinet, the sealing members are connected by being slid and inserted into grooves provided in the attachment guide member. Therefore, when performing maintenance or the like, the packing and cover member can be easily attached and detached by sliding them vertically relative to each other.

[0010] However, in the conventional storage facility, there is a risk that the mounting guide member is attached in a state where the mounting position is shifted in the thickness direction of the insulated door. The inventors discovered a problem that, when the mounting guide member is attached in a state where the mounting position is shifted, the mounting position of the sealing member attached to the mounting guide member may be shifted. In order to solve this problem, the inventors have come to constitute the subject of the present disclosure. Therefore, the present disclosure provides a reservoir in which a sealing member can be easily provided.

[0011] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or duplicate explanation of substantially the same configuration may be omitted. This is to avoid the following explanation becoming more redundant than necessary and to facilitate understanding by those skilled in the art. It should be noted that the accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to Figs. 1 to 4. In each drawing, the symbol FR indicates the front of the storage 1 in an installed state, the symbol UP indicates the upper side of the storage 1, and the symbol LH indicates the left side of the storage 1. In the following description, each direction is along the direction of the storage 1.

[0013] [1-1. Configuration] [1-1-1. Storage facility configuration] FIG. 1 is a front view of a storage facility 1 according to an embodiment of the present invention. The storage unit 1 is a vertical refrigerator, as shown in Fig. 1. The storage unit 1 includes a storage unit main body 2, a plurality of heat-insulating doors 4, and a machine room 6.

[0014] The storage body 2 comprises an outer box 5 that opens at the front, an inner box 7 that is contained inside the outer box 5 and also opens at the front, and insulation 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 with an insulated wall formed by filling the space surrounded by the outer box 5 and the inner box 7 with a thermal insulation material 8 (FIG. 4). In this embodiment, the outer box 5 and the inner box 7 are both integrally formed from a metal such as a stainless steel plate. The thermal insulation material 8 is made of polystyrene foam, hard urethane foam, or the like. The storage body 2 has a storage chamber 2A provided therein, and an opening 2B that is rectangular in front view is provided on the front side.

[0015] The outer box 5 and the inner box 7 may be made of a hard resin such as ABS resin, not limited to metal. The outer box 5 and the inner box 7 may be made of a combination of metal and hard resin. Also, for example, the storage body 2 may be formed by forming a plate-like member such as a steel plate into a housing shape, and combining the housing with an insulating wall formed by filling the inside of the housing with insulating material 8.

[0016] The machine room 6 is disposed above the storage body 2. A refrigeration device 61 that constitutes 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, and these are driven to send cold air into the storage room 2A. The capillary tube 65 may be another throttling mechanism such as a throttle valve.

[0017] The multiple heat-insulating doors 4 are rectangular door members that close the opening 2B of the storage body 2 in an openable and closable manner. In the storage body 1 of this embodiment, two pairs of heat-insulating doors 4 arranged in the left-right direction are provided, one above the other. These heat-insulating doors 4 are arranged with one side adjacent to each other. On the upper and lower surfaces of each heat-insulating door 4, hinges 11 are provided at locations located on the other 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 body 1 by these hinges 11. That is, the pair of heat-insulating doors 4 are so-called double-door doors. In this embodiment, the pair of heat-insulating doors 4 are so-called double-door doors formed symmetrically on the left and right. On the front surface of each of the insulating doors 4, handles 18 are provided on the side surfaces adjacent to each other in the left-right direction. The insulating door 4 corresponds to the "door" in this 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 as seen from the rear surface 4A side. One of the insulating doors 4 will be described below, but the other insulating doors 4 have the same structure. The heat-insulating door 4 is a flat plate-like member having a predetermined thickness, as shown in Fig. 2. The heat-insulating door 4 includes a heat-insulating door body 12 and a plurality of outer edge sealing members 50.

[0019] The outer edges of the front, both sides, top, bottom, and rear of the insulated door body 12 are all formed by a door exterior plate 13 integrally formed from a metal such as a stainless steel plate. The center of the rear of the insulated door body 12 is formed by a door interior plate 14 formed from a hard resin. The center of this door interior plate 14 protrudes further into the storage chamber 2A than the outer edge of the rear of the insulated door body 12. That is, in the insulated door 4, the rear surface 4A, which is the surface facing the storage body 2, is formed by the door interior plate 14 at the center, and the outer edges along each side are formed by the door exterior plate 13. The rear surface 4A of the heat-insulating door 4 corresponds to the "main body facing surface" of the present disclosure.

[0020] 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 polystyrene foam or hard urethane foam, as shown in FIG. The door exterior panel 13 is not limited to being made of metal, but may be made of a hard resin such as ABS resin.

[0021] Next, the rear surface of the insulating door body 12 will be described. The outer edge of the rear surface of the insulated door body 12 is formed by the ends of the door exterior panel 13 on the upper, lower and side sides, and by the end of the door interior panel 14 on the rear central side. An outer edge mounting groove 53 is provided around the entire periphery of the end of the door interior panel 14, i.e., the outer edge of the rear surface of the insulated door body 12 (FIG. 4). This outer edge mounting groove 53 opens on the door interior panel 14 side and has a groove shape that protrudes toward the door exterior panel 13. The width dimension of this outer edge mounting groove 53 is narrow near the opening in a cross section in the width direction and is wide at a portion located on the front side of the insulated door body 12. That is, the outer edge mounting groove 53 is formed in a so-called dovetail shape in a cross section perpendicular to the longitudinal direction of the outer edge mounting groove 53 (FIG. 4).

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

[0023] The outer edge sealing member 50 includes a bag-shaped sealing member main body 56 formed in a hollow shape with a space inside. An outer edge magnet housing portion 51 having a rectangular cross section is provided over the entire circumferential direction on the front side of the outer edge sealing member 50 in this space (FIG. 4). Furthermore, four rod-shaped outer edge magnets 52 are housed in this outer edge magnet housing portion 51 (FIG. 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 portion 51 along each side of the outer edge sealing member 50.

[0024] Next, the structure of the side surface 4B of the heat-insulating door 4 will be described. Fig. 3 is an exploded perspective view showing the heat-insulating door 4, the mounting guide member 24, and the sealing member 26. In Fig. 3, the side packing 28 and the fin member 32 made of a soft material are marked with dots for ease of explanation. The side surface 4B of one of the insulating doors 4 will be described below, but the other insulating door 4 has a similar structure. As shown in FIG. 3, a sealing member 26 is provided on a side surface 4B of each of the insulating doors 4 adjacent to the other insulating door 4 via an attachment guide member 24. The side surface 4B of the insulating door 4 corresponds to the "opposing surface" in this disclosure.

[0025] The mounting guide member 24 is made of a hard resin as a hard material. The mounting guide member 24 is a rail-shaped member having a length approximately equal to the side surface 4B of the heat-insulating door 4 and formed, for example, by extrusion molding, so that the cross section is C-shaped. The mounting guide member 24 is attached so that the vertical direction is along the vertical direction of the heat-insulating door 4. The width dimension of the mounting guide member 24 is formed to be approximately equal to the width dimension of the side surface 4B of the heat-insulating door 4. The mounting guide member 24 is fixed to the side surface 4B of the heat-insulating door 4 by screwing at several points on the bottom surface 24A. For this reason, a plurality of screw holes 12A are provided on the side surface 4B of the heat-insulating door 4. A plurality of screw holes are provided on the bottom surface 24A of the mounting guide member 24.

[0026] Fig. 4 is a cross-sectional view of the storage facility 1 taken along plane IV in Fig. 1. Plane IV is a plane perpendicular to the side surfaces 4B of each of a pair of insulated doors 4 arranged in the left-right direction. Fig. 4 shows a cross-section of the storage facility 1 taken along plane IV, the cross-section including each of the adjacent side surfaces of the pair of insulated doors 4. In Fig. 4, the insulating material 8 is indicated with a dot for ease of explanation. Fig. 5 is a plan view of the sealing member 26 and the mounting guide member 24. Fig. 5 shows end surfaces of the sealing member 26 and the mounting guide member 24 in a disassembled state. For ease of explanation, Fig. 5 shows the sealing member 26 with hatching.

[0027] A groove-shaped packing guide groove 24C is provided on the storage body 2 side of the mounting guide member 24 over the entire vertical direction of the mounting guide member 24. As shown in Figs. 4 and 5, the packing guide groove 24C is provided protruding 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 body 2 side is opened. An insertion portion 28F1 provided on the side surface packing 28 described later is inserted into the packing guide groove 24C.

[0028] In the packing guide groove 24C, a first heater holding portion 24D for holding a heater 36 described later is provided on the front side of the heat-insulating door 4. The first heater holding portion 24D is formed in a groove shape with a portion located on the other heat-insulating door 4 side being open.

[0029] A holding portion engaging piece 24E is provided on the front side of the heat-insulating door 4 of the first heater holding portion 24D. This holding portion engaging piece 24E is formed in a claw shape protruding from the front side of the heat-insulating door 4. A cover member engaging piece 30B provided on the cover member 30 described later is engaged with this holding portion engaging piece 24E.

[0030] In the packing guide groove 24C, a second heater holding part 24G capable of holding a heater 36 described later is provided on the rear surface 4A side of the thermal insulation door 4. The second heater holding part 24G is formed in a groove shape with an open portion located on the other side of the thermal insulation door 4. The second heater holding part 24G is disposed at a position closer to the storage chamber 2A than the first heater holding part 24D and the side surface of the thermal insulation door main body 12.

[0031] In the second heater holding portion 24G, a storage portion restricting portion 24H is provided on the rear surface 4A side of the insulating door 4. The storage portion restricting portion 24H has a flat surface facing the side surface 4B of the other insulating door 4. When the sealing member 26 is attached to the mounting guide member 24, the storage portion restricting portion 24H is disposed at a predetermined interval in the left-right direction with respect to the side surface magnet storage portion 28A provided in the side surface packing 28. The storage portion restricting portion 24H suppresses deformation of the side surface magnet storage portion 28A toward the side surface 4B of the one insulating 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. This locking portion 24F is provided to protrude from the bottom surface 24A toward the side surface 4B of the other insulated door 4, similar to the packing guide groove 24C. The tip of the locking portion 24F is curved like a claw. This locking portion 24F is inserted into a locking groove 30C provided in the cover member 30 described later.

[0033] The mounting guide member 24 is provided with an abutment portion 70. The abutment portion 70 extends from the rear end of the mounting guide member 24 and abuts against the rear surface 4A of the insulated door 4 to which the mounting guide member 24 is attached. In other words, when the mounting guide member 24 is attached to the insulated door 4, the mounting guide member 24 abuts against the side surface 4B of the insulated door 4 and the rear surface 4A of the insulated door 4. In this embodiment, the contact portion 70 extends from the side surface 4B of one of the insulating doors 4 along the rear surface 4A of the insulating door 4 with respect to the packing guide groove 24C.

[0034] 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 includes 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 disposed spaced apart from the fin portion 58 in the left-right direction.

[0035] The abutting portion 70 is provided with a rib-like protruding piece 71 extending toward the outer edge sealing member 50. The tip of the protruding piece 71 is disposed between the sealing member main body 56 and the fin portion 58. That is, in the storage container 1, the sealing member main body 56, the protruding piece 71, and the fin portion 58 are disposed in order from the storage chamber 2A side toward the exterior side of the storage container 1.

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

[0037] The contact portion 70 has an extension portion 72 extending toward the storage chamber 2A. The extension portion 72 is disposed in a position closer to the insulating door 4 than the side surface of the outer edge sealing member 50 located on the storage chamber 2A side in the front-rear direction of the storage cabinet 1. A flat surface portion 74 is provided at the tip of the extension portion 72. The flat surface portion 74 forms a flat surface that faces and is substantially parallel to the opening 2B.

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

[0039] The flat surface portion 74 is disposed at a predetermined distance in the left-right direction from the outer edge sealing member 50. As a result, in the storage container 1, even if the outer edge sealing member 50 is in close contact with the storage container main body 2 and deforms, the flat surface portion 74 is prevented from impeding the deformation of the outer edge sealing member 50.

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

[0041] The flat portion 74 is provided with a rib-shaped restricting piece 76 that protrudes toward the insulated door 4 on which the flat portion 74 is provided. The tip of the restricting piece 76 is disposed at a predetermined distance from the third heater holding portion 78. When the open insulated door 4 of the storage facility 1 is closed, the flat portion 74 may come into contact with the storage facility body 2 or a partition member that separates the opening 2B. In this case, the restricting piece 76 comes into contact with the third heater holding portion 78, thereby preventing the extension 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. 3 and 5, the sealing member 26 includes a side packing 28, a cover member 30, and a fin member 32, which are integrally molded. The sealing member 26 is a rail-shaped member having a length similar to that of the mounting guide member 24 and molded to have a C-shaped cross section. The sealing member 26 is attached so that its vertical direction is aligned with the vertical direction of the insulated door 4.

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

[0044] As shown in Fig. 3, both ends of the side magnet housing portion 28A are closed by the retaining member 35. The retaining member 35 is a plate-like member formed by bending so that the cross section is L-shaped. The retaining member 35 is attached to the side packing 28 by being inserted into each end in the up and down direction of the side magnet housing portion 28A. This prevents the side magnet 34 from falling off from the side packing 28.

[0045] A first seal portion 28B is provided on the side of the side magnet housing portion 28A facing the storage body 2. As shown in FIG. 4, the first seal portion 28B extends toward the outer edge sealing member 50. A second seal portion 28C is provided at the tip of the first seal portion 28B. The second seal portion 28C protrudes toward the storage body 2 and then bends and extends toward the other heat-insulating door 4. That is, in the heat-insulating door 4 located on the right side, the first seal portion 28B and the second seal portion 28C are formed so that their cross sections are C-shaped, as shown in FIG. 5. In the heat-insulating door 4 located on the left side, the first seal portion 28B and the second seal portion 28C are formed so that their cross sections are inverted C-shaped.

[0046] A tip portion 28C1 of the second seal portion 28C extends to a position approximately equal to the surface located on the other insulating door 4 side in the side magnet receiving portion 28A. The vertical length of this second seal portion 28C is shorter than the vertical length of the side gasket 28 and is approximately the same as the vertical length of the door interior panel 14.

[0047] 4 and 5, a fin portion 28D is provided on the first seal portion 28B on the side of the outer edge sealing member 50. The fin portion 28D extends toward the outer edge sealing member 50, and its tip is capable of abutting against the outer edge sealing member 50.

[0048] A connecting portion 28E is provided on the front side of the heat-insulating door 4 of the side magnet housing portion 28A. This connecting portion 28E is formed in a fin shape extending to the front side of the heat-insulating door 4. The tip of the connecting portion 28E is joined to the bottom surface 30A of the cover member 30.

[0049] An extension part 28F is provided on the side of the side magnet housing part 28A facing the side 4B of the insulated door 4. This extension part 28F extends from the side of the side magnet housing part 28A facing the side 4B of the insulated door 4 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 part 28F is formed in a substantially L-shaped cross section. An insertion part 28F1 having a T-shaped cross section is provided at the tip of the extension part 28F. This insertion part 28F1 is inserted into the packing guide groove 24C of the mounting guide member 24 as described above.

[0050] Next, the cover member 30 will be described. 3 and 5, the cover member 30 is made of a hard resin as a hard material. As shown in Fig. 4, the cross section of the cover member 30 is formed in a C-shape. As described above, the connecting portion 28E of the side packing 28 is connected to the end portion of the bottom surface 30A of the cover member 30 located on the side of the storage container body 2. As shown in Figures 4 and 5, a cover member engagement piece 30B is provided on the end of the bottom surface 30A of the cover member 30 that is located on the side of the storage cabinet main body 2. This cover member engagement piece 30B protrudes from the bottom surface 30A toward the side surface 4B of the heat-insulating door 4. The tip of the cover member engagement piece 30B is formed into a claw shape. As described above, the cover member engagement piece 30B engages with the holding portion engagement piece 24E. Furthermore, a rib 30B1 is provided on the cover member engagement piece 30B. The rib 30B1 protrudes from the bottom surface 30A toward the storage cabinet main body 2. The rib 30B1 closes the open portion of the first heater holding portion 24D in which the heater 36 is held.

[0051] A locking groove 30C is provided on the bottom surface 30A of the cover member 30 at an end located on the front side of the insulated door 4. The end where the locking groove 30C is provided protrudes from the bottom surface 30A toward the side surface 4B of the insulated door 4. The locking groove 30C has a groove shape in which a portion located on the side surface 4B of the insulated door 4 at the end is open. As described above, the locking portion 24F is inserted into 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 is made of soft material such as soft resin such as rubber, similar to the side packing 28. The fin member 32 extends toward the side surface 4B of the insulated door 4. The tip of the fin member 32 abuts against the side surface 4B of the insulated door 4.

[0053] 3, a linear heater 36 is sandwiched between the mounting guide member 24 and the sealing member 26. The heater 36 is a linear heat-generating member that heats the sealing member 26 to prevent condensation or freezing. In this embodiment, the heater 36 is an electric heating wire that generates heat when power is supplied thereto.

[0054] The heater 36 is arranged in a loop shape over the entire vertical direction 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 holding pieces 37. The heater holding pieces 37, together with the heater 36, are sandwiched between the mounting guide member 24 and the sealing member 26.

[0055] As shown in FIG. 4, as described above, the heater 36 is sandwiched between the first heater holding portion 24D, and further, the open portion of the first heater holding portion 24D is blocked by the rib 30B1, thereby fixing the heater 36 between the mounting guide member 24 and the sealing member 26. With this, when the heater 36 generates heat, it heats, for example, the connecting portion 28E on the side surface 4B of the heat-insulating door 4. Therefore, in the heat-insulating door 4, the occurrence of condensation or freezing is suppressed, for example, on the connecting portion 28E.

[0056] The heater 36 held by the first heater holding portion 24D can be further held by the second heater holding portion 24G or the third heater holding portion 78. When the heater 36 is held by 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 accommodating 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 extension portion 28F of the side packing 28, the first seal portion 28B, and the abutment portion 70 of the mounting guide member 24.

[0057] In this way, the heater 36 selectively heats multiple locations on the side packing 28. Therefore, in the heat-insulating door 4, condensation or freezing at specific locations on the side packing 28 can be suppressed.

[0058] As shown in Fig. 3, both ends in the up-down direction of the mounting guide member 24 and the sealing member 26 are closed by caps 38. As shown in Fig. 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 short direction of the side surface 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] A pair of insertion portions 38A protruding downward are provided on the back surface of the cap 38. The insertion portions 38A are inserted into the space surrounded by the mounting guide member 24 and the sealing member 26. This prevents dirt and dust 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 located on the other end side of the cap 38, and a screw hole is provided at 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 into the screw hole with a screw 40.

[0061] [1-2. Operation] The operation of the storage 1 configured as above will now be described. First, the procedure for attaching the mounting guide member 24 to the heat-insulating door body 12 will be described. The bottom surface 24A of the mounting guide member 24 abuts against the side surface 4B of the insulated door 4. In this state, the abutting portion 70 abuts against 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 mounted on the side surface 4B of the insulated door 4 while preventing misalignment. Next, the mounting guide member 24 is fixed to the side surface 4B of the heat-insulating door 4 by screwing the bottom surface 24A at several points.

[0062] Next, a procedure for attaching the sealing member 26 to the attachment guide member 24 will be described. First, the heater 36 is sandwiched in the heater holding groove 24E. Next, one end of the sealing member 26 is inserted into one end of the mounting guide member 24 while sliding it vertically, so that the sealing member 26 is fixed to the mounting guide member 24. As a result, sealing member 26 is fixed to mounting guide member 24 without using a fixing member, a tool, or the like. As a result, it is possible to reduce the number of parts of storage cabinet 1, and also to facilitate manufacturing and maintenance work of the refrigerator.

[0063] When the pair of insulated doors 4 of the storage facility 1 are closed, the outer edge magnets 52 are attracted to the storage facility main body 2 by magnetic force, and the side of the outer edge sealing member 50 facing the hinge 11 of the insulated door 4 and the areas along the top and bottom surfaces of the insulated door 4 are brought into close contact with the storage facility main body 2. The side magnets 34 of the sealing members 26 of the insulating doors 4 are attracted to each other by magnetic force. As a result, the extension parts 28F and the connecting parts 28E extend toward the side surface 4B of the other insulating door 4. Then, the housing part side surfaces 28A1 located on the other insulating door 4 side of the side magnet housing parts 28A are in close contact with each other, thereby sealing the space between the side surfaces 4B of the insulating doors 4.

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

[0065] Furthermore, a seal space S2 is formed on the side surface 4B of each insulating door 4, the seal space S2 being surrounded by the mounting guide member 24, the extension portion 28F, the first seal portion 28B, the fin portion 28D, and the outer edge sealing member 50. The air in the seal 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. The insulating air layer and the fin member 32 prevent heat from entering the inside of 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 from inside the storage chamber 2A.

[0066] In this way, the sealing member 26 is formed by integrally molding the side packing 28 made of soft resin and the cover member 30 made of hard resin, so that the sealing member 26 can seal between the side surfaces 4B of the insulated door 4 while having a predetermined strength. It is possible to prevent dust and dirt from accumulating between the side packing 28 and the cover member 30. Furthermore, when performing maintenance, cleaning, etc., the user does not need to remove the side gasket 28 and the cover member 30 separately, which makes it possible to prevent damage or falling off of the side gasket 28 and the cover member 30. In addition, there is no need to provide a structure or mechanism for connecting the side gasket 28 and the cover member 30, so the sealing member 26 can be made smaller, and the insulated door 4 can be made thinner and lighter.

[0067] 4, in the sealing member 26, a flat portion 74 is disposed 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 with the front-rear direction, in other words, the direction from the storage chamber 2A toward the front side of the insulating door 4. The length dimension in the left-right direction of the plane is a length dimension that does not contact the side gasket 28 and the outer edge sealing member 50 in either case of opening or closing the pair of insulating doors 4. This allows the sealing member 26 to suppress the intrusion of heat into the inside of the storage chamber 2A and the leakage of cold air from the inside of the storage chamber 2A without impeding the functions of the side gasket 28 and the outer edge sealing member 50.

[0068] In addition, the flat portion 74 is disposed close to the front surface of the first seal portion 28B from the mounting guide member 24 side. As a result, even if the side packing 28 of the sealing member 26 is deformed so as to approach the front surface side, the flat portion 74 corrects the deformation at a predetermined position. As a result, the sealing member 26 is prevented from being deformed and from being displaced.

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

[0070] In this way, side gasket 28, which is a soft member of sealing member 26, is prevented from being deformed or displaced by each part of mounting guide member 24. For this reason, in storage facility 1, it is possible to reduce the frequency of maintenance and replacement of sealing member 26, in which side gasket 28 and cover member 30 are integrally formed.

[0071] In addition, the mounting guide member 24 is easily positioned by the abutment portion 70 abutting against the rear surface 4A of the heat-insulating door 4. Therefore, in the storage facility 1, it is possible to suppress the occurrence of positional deviations due to deformation, dimensional tolerances, and the like over the entire heat-insulating door 4.

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

[0073] This allows the mounting guide member 24 to be easily positioned in the front-rear direction of the insulating door 4. Therefore, the mounting guide member 24 can be easily mounted on the side surface 4B of the insulating door 4 while preventing misalignment. Furthermore, it is possible to suppress variations in the quality of products produced during manufacturing in the storage facility 1. As a result, in the storage facility 1, the adhesion between the heat-insulating door 4 and the storage facility main 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 flat surface facing the opening 2B. As a result, a flat surface that closes a portion of the opening 2B is provided in the mounting guide member 24. Therefore, in the storage cabinet 1, the mounting guide member 24 prevents air in the storage chamber 2A from leaking out to the outside of the storage cabinet 1 and prevents air outside the storage cabinet 1 from entering the storage chamber 2A.

[0075] As in this embodiment, the abutment portion 70 may be provided with a third heater holding portion 78 that holds a heater 36 that heats 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 portion of the side packing 28. Therefore, in the heat-insulating door 4, condensation or freezing at the predetermined portion of the side packing 28 can be suppressed.

[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. As a result, in the storehouse 1, the gap between the side surfaces 4B of the heat-insulating door 4 can be sealed while the sealing member 26 has a predetermined strength.

[0077] (Other embodiments) As described above, the first embodiment has been described 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 in which modifications, substitutions, additions, omissions, etc. are made. In addition, it is also possible to combine the components described in the first and second embodiments to create new embodiments. Therefore, other embodiments will be exemplified below.

[0078] In the above-described embodiment, the storage unit 1 is a four-door upright refrigerator, but the present invention is not limited to this and may be applied to refrigerators such as under-counter refrigerators and household refrigerators having multiple storage compartments formed by dividing them with partitions or the like. Further, for example, in the storage cabinet 1, not only the outer edge sealing member 50 but also the side gasket 28 may be formed hollow and divided into a plurality of spaces.

[0079] Furthermore, for example, the storage cabinet 1 may be a single-door refrigerator. Even in such a refrigerator, the mounting guide member 24 can 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 preventing misalignment. Furthermore, it is possible to suppress variations in the quality of products produced during manufacturing in the storage facility 1. As a result, in the storage facility 1, the adhesion between the heat-insulating door 4 and the storage facility main body 2 is improved, and the cooling effect can be improved.

[0080] In the embodiment described above, the contact portion 70 is provided with the extending portion 72, the flat portion 74, and the 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 above-described embodiment, the heater 36 is provided as a heat generating member for heating the sealing member 26. However, the present invention is not limited to this, and may be, for example, a refrigerant pipe through which the refrigerant that has been heat exchanged in the condenser 63 flows.
