[0007] [Figure 1] FIG. 1 is a perspective view of a storage facility according to a first embodiment; [Figure 2] Plan view of the opposing part of the storage door seen from above [Figure 3] FIG. 10 is a plan view of the sealing member of one door of the storage facility viewed from above. DETAILED DESCRIPTION OF THE INVENTION

[0008] (Findings that formed the basis of this disclosure) At the time the inventors arrived at the idea of the present disclosure, there was a technology in which a pair of doors arranged in the left-right direction each had a sealing member, and the magnet housing portions formed in the sealing members came into close contact with each other to close the gap between the pair of doors, as in Patent Document 1. However, the inventors discovered a problem in that the conventional technology did not take into consideration how to prevent the phenomenon in which one magnet housing portion deforms to approach the other magnet housing portion, causing the two magnet housing portions to overlap in the front-to-rear direction, and the subject matter of the present disclosure was formed to solve this problem. Therefore, the present disclosure provides a storage cabinet that can improve the thermal insulation of the storage chamber by making it easier to close a pair of doors by moving one magnet housing section away from the other magnet housing section.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanation than necessary may be omitted. For example, detailed explanation of already well-known matters or redundant explanation of substantially the same configuration may be omitted. 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.

[0010] (Embodiment 1) Hereinafter, the first embodiment will be described with reference to Figures 1 to 3. In each figure, the symbol FR indicates the front of the storage facility 1 in the installed state, the symbol UP indicates the upper side of the storage facility 1, and the symbol LH indicates the left side of the storage facility 1. In the following description, each direction is along the direction of the storage facility 1. In the following description, the surface on which the opening 2B is provided is referred to as the front side, and the direction that the front side faces is referred to as the forward side. In addition, the direction along the vertical direction in the installed state of the storage facility 1 is referred to as the up-down direction, and the direction along the horizontal direction is referred to as the front-rear direction and the left-right direction.

[0011] [1-1.Configuration] [1-1-1. Storage structure] Fig. 1 is a perspective view of a storage cabinet 1 according to an embodiment of the present invention. Fig. 2 is a plan view of the facing part 20 as viewed from above. The storage cabinet 1 is a vertical refrigerator, as shown in Fig. 1. The storage cabinet 1 includes a storage cabinet main body 2, a plurality of doors 4, and a machine room 6.

[0012] The storage body 2 comprises an outer box 5 that opens at the front, an inner box 7 that is housed inside the outer box 5 and also opens at the front, and a heat insulating material provided in the space between the outer box 5 and the inner box 7. The storage body 2 is a box body with insulated walls formed by filling the space surrounded by the outer box 5 and the inner box 7 with insulating material. In this embodiment, the outer box 5 and the inner box 7 are both made of metal such as stainless steel plate. The insulating material may be polystyrene foam, hard urethane foam, or the like.

[0013] 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 surface. An opening plane P is a plane including the front surface on which the opening 2B is provided. An opening edge portion 2C that surrounds the entire periphery of the opening 2B is provided on the opening surface P of the storage cabinet main body 2. The opening edge portion 2C has a flat surface that is located on approximately the same plane as the opening surface P of the storage cabinet main body 2. The storage body 2 is provided with a partition 2D that separates the opening 2B. The partition 2D is a beam-shaped member that extends in the left-right direction. The partition 2D is formed in the shape of a metal box, and is configured by filling the interior with heat insulating material 8. Each end of the partition 2D is connected to the midpoint in the up-down direction of each of the opening edge portions 2C located in the left-right direction.

[0014] The outer box 5 and the inner box 7 are not limited to being made of metal, but may be made of hard resin such as ABS resin, etc. Also, the outer box 5 and the inner box 7 may be made of a combination of metal and hard resin. For example, the storage body 2 may be formed by combining a plate-shaped member such as a steel plate formed into a housing shape and an insulating wall formed by filling the inside of the housing with insulating material 8.

[0015] The machine room 6 is disposed above the storage body 2. A refrigeration device 81 that constitutes a refrigeration cycle is housed inside the machine room 6. More specifically, the refrigeration device 81 includes a compressor 82, a condenser 83, a condenser blower 84, a capillary tube 85, an electrical box 86, and an evaporator 87, and when these components are driven, cold air is sent into the storage chamber 2A. In this embodiment, the evaporator 87 is provided inside the storage body 2. The capillary tube 85 may be another throttling mechanism such as a throttle valve.

[0016] The multiple doors 4 are rectangular door members that can be opened and closed to close the opening 2B of the storage cabinet main body 2. In the storage cabinet 1 of this embodiment, two sets of doors 4 are provided, one above the other, with one set being a pair of doors 4 arranged in the left-right direction. The doors 4 are arranged on either side of the partition 2D, with one set above the partition 2D and the other set below the partition 2D.

[0017] These doors 4 are arranged adjacent to each other on one side. Each of the pair of doors 4 can be opened and closed in the left-right direction of the storehouse 1 by means of a hinge 11. The pair of doors 4 are so-called double-doors.

[0018] A handle 18 is provided on the front surface of the door 4 at a position close to the opposing surface 4B adjacent to each other in the left-right direction. One door 4 will be described below, but the other doors 4 have the same structure. The door 4 is a flat plate-like member having a predetermined thickness, as shown in Fig. 2. The door 4 includes a door body 12 and a plurality of body sealing members 13.

[0019] The rear surface of the door body 12 is constituted by a door interior panel 14 made of hard resin. The inside of these door bodies 12 is filled with a heat insulating material 8 such as expanded polystyrene or hard urethane foam (see FIG. 2).

[0020] The main body sealing member 13 is made of a soft resin such as rubber or soft polyvinyl chloride, and is a sealing member that is elastically deformable, such as a so-called packing or gasket. In this embodiment, the main body sealing member 13 is formed in a rectangular shape, and is arranged in a frame shape on the door main body 12 by being attached to the groove shape described above.

[0021] The main body sealing member 13 is formed in a hollow shape with an internal space. Four rod-shaped magnets are housed in the internal space of the main body sealing member 13, extending over the entire circumferential direction. Each of the magnets has a length approximately equal to that of each side of the rear surface of the door main body 12. Each of the magnets is inserted into the internal space of the main body sealing member 13 along each side of the main body sealing member 13.

[0022] [1-1-2. Configuration of mounting components] FIG. 2 shows the mounting member 30 and the sealing member 50 in an exposed state. The space between a pair of doors 4 facing each other in the left-right direction constitutes an opposing portion 20. At the position of the opposing portion 20 of the doors 4, a sealing member 50 that closes the gap between the pair of doors 4 and an attachment member 30 to which the sealing member 50 can be attached are arranged. The attachment member 30 is provided on an opposing surface 4B, which is the surface of the doors 4 that is located at the opposing portion 20.

[0023] The mounting member 30 is made of a hard resin as a hard material. The mounting member 30 is a long member having a length approximately equal to that of the opposing surface 4B of the door 4. The mounting member 30 is a plate-like member formed, for example, by extrusion molding, so that the end faces are C-shaped.

[0024] The mounting member 30 has a flat base 31 that extends over the entire longitudinal direction of the mounting member 30. The base 31 is attached so that its longitudinal direction is aligned with the vertical direction of the door 4 and its plate thickness direction is aligned with the left-right direction. The width dimension of this mounting member 30, which is the dimension along the front-to-rear direction, is formed to be approximately the same as the width dimension of the opposing surface 4B of the door 4. The mounting member 30 is attached to the opposing surface 4B of the door 4 with fastening members 32.

[0025] As shown in Fig. 2, a front locking piece 33 is formed on the end of the base 31 on the front side of the door 4. The front locking piece 33 is formed to protrude from the base 31 toward the opposing surface 4B of the other door 4. The tip of the front locking piece 33 is formed in a claw shape that curves toward the front side of the door 4. The front locking piece 33 engages with a second cover locking piece 60 provided on the cover part 52, which will be described later.

[0026] A central engagement piece 34 is formed in approximately the center in the front-to-rear direction of the base 31. The central engagement piece 34 is formed to protrude from the base 31 toward the opposing surface 4B of the other door 4. In a plan view, the tip of the central engagement piece 34 is bent in an L-shape toward the storage cabinet main body 2. A first cover engagement piece 59 provided on the cover part 52, which will be described later, engages with this central engagement piece 34.

[0027] A first heater holding portion 37 that holds the heater 36 is formed at the end of the base 31 closer to the storage cabinet main body 2 than the central engagement piece 34. The first heater holding portion 37 is formed in a groove shape that is open at the front and recessed toward the rear. In the front-to-rear direction of the storage cabinet 1, the first heater holding portion 37 is positioned approximately flush with the outer peripheral edge 12A of the rear surface of the door main body 12, or is positioned closer to the front of the door 4 than the outer peripheral edge 12A.

[0028] 2, an extension portion 35 is formed on the base 31. The extension portion 35 extends from the rear end of the first heater holding portion 37 toward the storage chamber 2A, extends along the rear surface of the door 4, and abuts against the outer peripheral edge 12A of the rear surface of the door main body 12 to which the mounting member 30 is attached. Therefore, when the mounting member 30 is attached to the door 4, the base 31 abuts against the opposing surface 4B of the door 4, and the extension portion 35 abuts against the rear surface of the door 4.

[0029] This allows the mounting member 30 to be easily positioned in the front-rear direction of the door 4. Therefore, the mounting member 30 can be easily attached to the opposing surface 4B of the door 4 while preventing misalignment. The entire extension portion 35 is disposed at a position closer to the storage cabinet main body 2 than the rear surface of the door 4 and the outer peripheral edge 12A.

[0030] The extending portion 35 is formed with a second heater holding portion 38 capable of holding the heater 36. The second heater holding portion 38 is formed in a groove shape that is open on the opposing portion 20 side and recessed toward the main body sealing member 13 side.

[0031] A receiving portion 39 is formed on the rear side of the second heater holding portion 38 in the extending portion 35, i.e., on the opposite side to the facing portion 20. A locked portion 40 of the receiving portion 39 is formed substantially perpendicular to the opening surface P. The receiving portion 39 is also formed to match the shape of a locking portion 67 of the urging member 65, which will be described later. A slit-shaped opening is formed in the receiving portion 39 on the opposite side to the facing portion 20. The locked portion 40 and the slit-shaped opening form a substantially T-shape for the receiving portion 39.

[0032] A restricting portion 41 extending rearward is formed on the extending portion 35. The restricting portion 41 is formed at a position on the extending portion 35 that is farthest from the opposing portion 20. The restricting portion 41 is formed in a substantially T-shape when viewed from above or below.

[0033] A flat portion 42 is formed at the tip of the rear portion of the restricting portion 41. The flat portion 42 has a flat plate shape and is disposed opposite the opening surface P. The rear end surface of the flat portion 42 forms a plane that faces the opening surface P and is substantially parallel to it. The flat portion 42 includes a stopper portion 43 that protrudes toward the opposing portion 20. The stopper portion 43 is formed so as to protrude toward the opposing portion 20 beyond the plate-like member of the restricting portion 41 that extends in the front-rear direction.

[0034] The flat surface 42 forms a flat surface on the mounting member 30 that blocks a portion of the opening 2B when the mounting member 30 is viewed from the side of the storage cabinet main body 2. This prevents air from inside the storage chamber 2A from leaking out to the outside of the storage cabinet 1 and prevents air from outside the storage cabinet 1 from entering the storage chamber 2A.

[0035] The flat surface portion 42 is disposed at a predetermined distance in the left-right direction from the main body sealing member 13. This prevents the flat surface portion 42 from interfering with the deformation of the main body sealing member 13 in the storage cabinet 1, even when the main body sealing member 13 is deformed due to its close contact with the storage cabinet main body 2. The extending portion 35 is formed with a second restricting portion 41A extending rearward from the second heater holding portion 38. The second restricting portion 41A is formed in a substantially T-shape when viewed from above or below.

[0036] [1-1-3. Configuration of sealing material] 3 is a plan view of the sealing member 50 of the right door as seen from above. In FIG. 3, the end face of the upper part of the sealing member 50 is shown.

[0037] 2 and 3, the sealing member 50 includes a side packing 51, a cover portion 52, and a front fin portion 53, which are integrally molded. The sealing member 50 is a long, plate-like member that has a length approximately the same as that of the mounting member 30 and is molded as a whole so that the end faces are C-shaped. The sealing member 50 is attached so that its longitudinal direction is aligned with the vertical direction of the door 4.

[0038] The rear part of the sealing member 50 is constituted by a side gasket 51. The side gasket 51 is disposed in a position facing the opening 2B. The side gasket 51 functions as a member that closes the facing part 20 so as to prevent the cool air from escaping from the storage chamber 2A. A contact portion 54 is joined to the opposing portion 20 side of the side packing 51. Furthermore, the contact portion 54 and the cover portion 52 are connected via a connecting portion 55. A front fin portion 53 is integrally formed at the front end of the cover portion 52.

[0039] 2 and 3, the magnet accommodating portion 56 formed in the side packing 51 includes a contact portion 54 that forms the entire plane facing the other door 4. The contact portion 54 is formed in a plate shape that is provided over the entire longitudinal direction of the side packing 51. The contact portion 54 is formed integrally with the side packing 51.

[0040] The contact surfaces of the contact portions 54 on the opposing portions 20 side come into close contact with each other when the pair of doors 4 are closed. The contact surfaces are formed to be smooth. A magnet 57 is arranged on the back side of the contact surface of the contact portions 54 so as to come into contact with it.

[0041] The contact portion 54 has an extension portion 58 that extends from the magnet storage portion 56 to the front side of the door 4. The extension portion 58 has a flat surface that is continuous with the contact surface, and is bent at a predetermined angle relative to the contact surface in a direction away from the opposing other door 4. The connecting portion 55 is joined to the front end of the extension portion 58. The cover portion 52 is joined to the front end of the connecting portion 55.

[0042] The cover portion 52 is formed of a hard resin, which is a material harder than the contact portion 54. As shown in Fig. 3, the cover portion 52 is formed into a plate shape with a C-shaped end face.

[0043] A first cover engaging piece 59 is formed at the rear end of the cover part 52. This first cover engaging piece 59 protrudes toward the door main body 12 to which the sealing member 50 is attached. The tip of the first cover engaging piece 59 is formed in a claw shape. As described above, the cover engaging piece 59 engages with the central engaging piece 34.

[0044] A second cover locking piece 60 is formed at the front end of the cover part 52. The second cover locking piece 60 is formed to protrude toward the door main body 12 to which the sealing member 50 is attached. The tip of the second cover locking piece 60 is formed in a claw shape and is formed to protrude toward the storage cabinet main body 2. As described above, the second cover locking piece 60 engages with the front locking piece 33.

[0045] A front fin portion 53 is integrally formed at the tip of the front portion of the second cover portion locking piece 60. Like the side gasket 51, this front fin portion 53 is made of a soft material such as soft resin such as rubber. The front fin portion 53 is formed so as to extend toward the opposing surface 4B of the door 4. The tip of the front fin portion 53 abuts against the opposing surface 4B of the door 4.

[0046] The side packing 51 is made of a soft resin that is an elastically deformable material such as rubber or soft polyvinyl chloride. The side packing 51 is an elastically deformable member. The end face of the side packing 51 is formed in an L-shape, and a magnet accommodating section 56 is provided at a location corresponding to a corner of the L-shape, with the end face partitioned into a rectangular space.

[0047] A rod-shaped magnet 57 is inserted into the magnet storage section 56. One magnetic pole of the magnet 57 is arranged on the storage main body 2 side, and the other magnetic pole is arranged on the front side of the door 4. The magnets 57 provided on each of the pair of doors 4 are arranged so that adjacent magnetic poles are different from each other in the left-right direction when the pair of doors 4 are closed. In other words, the magnet 57 provided on one door 4 of the pair of doors 4 is inserted into the magnet storage section 56 so that the arrangement of the magnetic poles of the magnet 57 provided on the other door 4 is opposite to that in the front-to-back direction.

[0048] The side gasket 51 has a first seal portion 61. The first seal portion 61 is continuous with the surface of the magnet storage portion 56 facing the storage cabinet main body 2, and has a flat plate shape extending in the left-right direction away from the magnet storage portion 56. As shown in FIGS. 2 and 3 , at least the surface of the first seal portion 61 facing the storage cabinet main body 2 is arranged approximately parallel to the opening surface P of the storage cabinet main body 2. The first seal portion 61 corresponds to the "seal portion" of the present disclosure.

[0049] 3, an inner fin portion 62 is formed in the first seal portion 61 on the side opposite to the magnet accommodating portion 56. As shown in FIG. 2, the inner fin portion 62 has a fin shape that extends toward the main body sealing member 13 and whose tip abuts against the main body sealing member 13.

[0050] As shown in FIG. 2, when the door 4 is closed, the first seal portion 61 and the inner fin portion 62 are sandwiched between the opening edge portion 2C or the partition body 2D and the main body sealing member 13. Furthermore, when a user cleans the door 4, the first seal portion 61 and the inner fin portion 62 may be pulled in a direction away from the door body 12. In addition, when the door 4 is closed, the inner fin portion 62 is exposed to cold air from the storage compartment 2 A. Therefore, the inner fin portion 62 is affected by temperature changes as the door 4 is opened and closed.

[0051] In this embodiment, inner fin portion 62 is formed by being bent at shallow angles at multiple locations midway in the left-right direction toward main body sealing member 13, in other words, toward door 4. This prevents first seal portion 61 and inner fin portion 62 from irregularly deforming, such as separating from main body sealing member 13, even when subjected to operations such as cleaning or temperature changes. Therefore, in storage cabinet 1, when door 4 is closed, the creation of a gap between storage cabinet main body 2 and door 4 is prevented.

[0052] 2 and 3, a second seal portion 63 is provided midway in the left-right direction of the first seal portion 61. This second seal portion 63 is formed so as to protrude rearward from a position between the end face of the magnet accommodating portion 56 opposite the opposing portion 20 and the opposing surface 4B of the door 4 in the left-right direction of the first seal portion 61, and then bend and extend toward the magnet accommodating portion 56. The end face of the second seal portion 63 is formed so as to be L-shaped.

[0053] The tip of the second seal portion 63 is formed so as to extend in the left-right direction to a position approximately the same as the surface of the magnet housing portion 56 located on the other door 4 side.

[0054] As shown in Figure 3, a biasing member 65 is provided at a midpoint in the left-right direction of the first seal portion 61. The biasing member 65 extends in a substantially linear manner toward the front side of the storage cabinet 1, in other words, toward the rear side of the door 4, when viewed from above. The biasing member 65 has a shaft portion 66 formed in a flat plate shape in the front-rear direction. The shaft portion 66 is formed to extend substantially perpendicular to the opening plane P. A base 68 constituting the rear end of the biasing member 65 is disposed at a position farther from the opposing portion 20 than the base of the second seal portion 63. The base 68 corresponds to the "base" of the present disclosure. Although the biasing member 65 is formed integrally with the first seal portion 61, it may be joined thereto.

[0055] A locking portion 67 having a substantially T-shaped end face is provided at the tip of the biasing member 65. The locking portion 67 is inserted into the receiving portion 39 of the mounting member 30, as shown in FIG.

[0056] The biasing member 65 is made of a rubber-like resin. As shown in Fig. 3, the biasing member 65 is not molded with the shaft portion 66 bent in advance. As shown in Fig. 2, when the biasing member 65 is attached to the door 4, it is bent at an angle of about 60 to 120 degrees toward the facing portion 20.

[0057] As a result, when the biasing member 65 is elastically deformed and the locking portion 67 is locked to the receiving portion 39, an elastic force is generated that causes the biasing member 65 to return to the shape shown in FIG.

[0058] Because the locking portion 67 is locked to the receiving portion 39 by this elastic force, a force acts on the first seal portion 61 in a direction away from the opposing portion 20 via the base portion 68 of the biasing member 65. Because the first seal portion 61 and the magnet accommodating portion 56 are formed integrally, a stress acts on the magnet accommodating portion 56 in a direction away from the opposing portion 20 by this elastic force.

[0059] Each portion of the sealing member 50 has a different hardness. The contact portion 54, the side packing 51, the cover portion 52, the front fin portion 53, the connecting portion 55, and the biasing member 67 are formed from the same resin material. This makes it possible to easily join the contact portion 54, the side packing 51, the cover portion 52, the front fin portion 53, the connecting portion 55, and the biasing member 67, which have different hardnesses. This makes it possible to easily form the contact portion 54, the side packing 51, the cover portion 52, the front fin portion 53, the connecting portion 55, and the biasing member 67 integrally, making it possible to easily manufacture the sealing member 50.

[0060] [1-2. Operation] When the doors 4 come into contact with the storage cabinet main body 2, the sealing members 50 of the pair of doors 4 are attracted to each other by the magnetic force of the magnets 57. The contact portions 54 of the two sealing members 50 come into close contact with each other, thereby closing the opposing portion 20. Figure 2 shows a state in which the right sealing member 50 is deformed and adheres to the left sealing member 50.

[0061] 2, when the right door 4 is opened, the shaft 66 tries to return to the state shown in Fig. 3, and the elastic force of the biasing member 65 is generated, causing the magnet accommodating portion 56 to move in a direction away from the opposing portion 20. This makes it possible to prevent the two magnet accommodating portions 56 from overlapping in the front-to-rear direction when the right door 4 is closed.

[0062] Furthermore, if the elastic force of the biasing member 65 causes the magnet accommodating portion 56 to move too far away from the facing portion 20, the distance between the two magnets 57 may become too large. In this case, when closing one door 4 while the other door 4 is closed, the contact portions 54 may not come into contact with each other, and the facing portion 20 may not be blocked. In this embodiment, the stopper portion 43 of the restricting portion 41 is formed in a direction away from the facing portion 20 relative to the base portion 68 of the biasing member 65, so the base portion 68 does not move in a direction away from the facing portion 20 relative to the stopper portion 43. In other words, the stopper portion 43 can prevent the magnet accommodating portion 56 from moving too far away from the facing portion 20. This prevents the distance between the two magnets 57 from becoming too large, causing the contact portions 54 to not come into contact with each other and preventing the facing portion 20 from being blocked.

[0063] The shape of the end portion of the second restricting portion 41A or the second heater holding portion 38 on the magnet accommodating portion 56 side may be changed to prevent the magnet accommodating portion 56 from moving too far away from the facing portion 20. For example, the end portion of the second restricting portion 41A on the facing portion 20 side shown in FIG. 2 may be formed to extend further toward the magnet accommodating portion 56. Also, for example, the end portion of the second heater holding portion 38 on the facing portion 20 side shown in FIG. 2 may be formed to extend further toward the magnet accommodating portion 56. In this case, if the magnet accommodating portion 56 moves too far away from the facing portion 20 due to the elastic force of the biasing member 65, the second restricting portion 41A or the second heater holding portion 38 will come into contact with the magnet accommodating portion 56, thereby preventing the magnet accommodating portion 56 from moving.

[0064] In the pair of doors 4, the magnet 57 provided on one door 4 is arranged so that the magnetic poles of the magnet 57 provided on the other door 4 are arranged in the opposite front-to-back direction. Therefore, when one door 4 is closed and the other door 4 is closed, the magnet accommodating portion 56 of the other door 4 moves in a direction away from the opposing portion 20 due to the repulsion of magnetic forces. However, if the other door 4 is closed at a high speed, for example, if the other door 4 is closed forcefully, the magnet accommodating portion 56 does not move due to the repulsion of magnetic forces. In this embodiment, the biasing member 65 constantly applies stress to the magnet accommodating portion 56 in a direction away from the opposing portion 20.

[0065] The biasing member 65 is configured so that the stress acting on the magnet accommodating portion 56 in the direction away from the facing portion 20 due to the elastic force of the biasing member 65 is weaker than the force of attraction between the two magnets 57. In other words, the biasing member 65 is configured so that the elastic force does not cause the contact portions 54 to come into contact with each other and the facing portion 20 to be blocked.

[0066] [1-3. Effects, etc.] As explained above, the storage cabinet 1 in this embodiment comprises a storage cabinet main body 2 having a storage chamber 2A, and a double-door 4 that closes an opening surface P including the opening 2B of the storage cabinet main body 2, the doors 4 each comprising an attachment member 30 provided on the opposing portion 20 side where the doors 4 face each other, and a sealing member 50 attached to the attachment member 30, the sealing member 50 comprising a first seal portion 61 (seal portion) that faces the opening surface P, the first seal portion 61 comprising a magnet storage portion 56 and a biasing member 65 that stands toward the door 4 from a position that faces the storage chamber 2A when the door 4 is closed, the attachment member 30 comprising a receiving portion 39 at a position closer to the opposing portion 20 than the base 68 of the biasing member 65, and the tip of the biasing member 65 is engaged with the receiving portion 39 by being elastically deformed. According to this configuration, stress acts on the first seal portion 61 via the base portion 68 due to the elastic force of the biasing member 65, and stress acts on the magnet accommodating portion 56 formed in the first seal portion 61 in a direction away from the opposing portion 20. Therefore, by moving one magnet accommodating portion 56 away from the other magnet accommodating portion 56, the pair of doors 4 can be easily closed. This improves the thermal insulation of the storage chamber 2A.

[0067] Furthermore, the receiving portion 39 may support the tip of the biasing member 65 by bending the biasing member 65 in a direction substantially perpendicular to the protruding direction of the base portion 68 . According to this configuration, by engaging the locking portion 67 with the receiving portion 39, the shaft portion 66 is bent, and an elastic force can be generated in the biasing member 65.

[0068] In addition, the urging member 65 has a shaft portion 66 formed in a flat plate shape protruding from a base portion 68, and a locking portion 67 formed at the tip of the shaft portion 66 approximately perpendicular to the shaft portion 66, and the receiving portion 39 has a locked portion 40 that supports the locking portion 67, and the locked portion 40 may be formed in a direction parallel to the protruding direction of the base portion 68. According to this configuration, by engaging the engaging portion 67 with the locked portion 67 of the receiving portion 39, the shaft portion 66 bends, and an elastic force can be generated in the biasing member 65. Furthermore, by engaging the engaging portion 67 with the receiving portion 39, the shaft portion 66 bends at a substantially right angle, and a larger elastic force can be generated than when the shaft portion 66 is bent at an acute angle.

[0069] The mounting member 30 may also include a restricting portion 41 erected toward the opening surface P at a position farther from the opposing portion 20 than the base portion 68 of the biasing member 65 is. According to this configuration, when the base 68 abuts against the restricting portion 41, the magnet accommodating portion 56 does not move any further due to the elastic force of the biasing member 65. As a result, the restricting portion 41 can regulate the amount of movement of the magnet accommodating portion 56 in the direction away from the opposing portion 20.

[0070] (Other embodiments) As described above, the above-mentioned first embodiment has been described as an example disclosed in the present application. However, the technology in the present disclosure is not limited to this, and can be applied to embodiments in which modifications, substitutions, additions, omissions, etc. are made. Furthermore, it is also possible to combine the components described in the above-mentioned first embodiment to create new embodiments. Therefore, other embodiments will be exemplified below.

[0071] Although the locking portion 67 has an end face formed in a substantially T-shape, the shape is not limited thereto. The locking portion 67 only needs to be formed so as to be able to be locked to the receiving portion 39, and may be formed, for example, in an arc shape or in a claw shape that protrudes to one side relative to the shaft portion 66. In this case, the shape of the locked portion 40 of the receiving portion 39 can be changed as appropriate depending on the shape of the locking portion 67.

[0072] The receiving portion 39 may be disposed closer to the opposing portion 20 than the base portion 68 of the biasing member 65. For example, the receiving portion 39 may be formed between the first heater holding portion 37 and the second heater holding portion 38. In this case, the angle at which the shaft portion 66 is bent becomes acute, but the elastic force of the biasing member 65 can apply stress to the magnet accommodating portion 56 in a direction away from the opposing portion 20. The elastic force of the biasing member 65 can be adjusted as appropriate by, for example, changing the hardness of the resin or the thickness of the shaft portion 66.

[0073] It should be noted that the above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents.

[0074] (Addendum) The above description of the embodiments discloses the following techniques.

[0075] (Technology 1) A storage cabinet comprising a storage cabinet main body having a storage chamber, and double-doors that close an opening surface including an opening of the storage cabinet main body, the doors comprising mounting members provided on the opposing sides of the doors facing each other, and sealing members attached to the mounting members, the sealing members comprising a sealing portion that faces the opening surface, the sealing portion comprising a magnet storage portion and a biasing member that stands toward the door from a point that faces the storage chamber when the door is closed, the mounting member comprising a receiving portion at a position closer to the opposing portion than the base of the biasing member, and the tip of the biasing member is engaged with the receiving portion by being elastically deformed. With this configuration, the elastic force of the biasing member applies stress to the seal portion via the base, and the stress acts on the magnet housing portion formed in the seal portion in a direction away from the opposing portion. Therefore, by moving one magnet housing portion away from the other magnet housing portion, the pair of doors can be easily closed. This improves the thermal insulation of the storage compartment.

[0076] (Technology 2) The storage container according to Technology 1, wherein the receiving portion bends the urging member in a direction substantially perpendicular to the protruding direction of the base portion to support the tip of the urging member. According to this configuration, by engaging the locking portion with the receiving portion, the shaft portion bends, and an elastic force can be generated in the biasing member.

[0077] (Technology 3) A storage facility according to Technology 2, wherein the urging member comprises a shaft portion formed in a flat plate shape protruding from the base portion, and a locking portion formed at the tip of the shaft portion approximately perpendicular to the shaft portion, and the receiving portion comprises a locked portion that supports the locking portion, and the locked portion is formed in a direction parallel to the protruding direction of the base portion. With this configuration, by engaging the locking portion with the locked portion of the receiving portion, the shaft bends and an elastic force can be generated in the biasing member. Also, by engaging the locking portion with the receiving portion, the shaft bends at a substantially right angle, which can generate an elastic force greater than that generated when the shaft is bent at an acute angle.

[0078] (Technology 4) A storage facility described in any one of technologies 1 to 3, wherein the mounting member is provided with a regulating portion that is erected toward the opening surface at a position farther from the opposing portion than the base portion. With this configuration, when the base abuts against the restricting portion, the elastic force of the biasing member prevents the magnet accommodating portion from moving any further, thereby allowing the restricting portion to regulate the amount of movement of the magnet accommodating portion in the direction away from the opposing portion.
