[Effects of the Invention]
[0006] The storage facility described in this disclosure can improve the thermal insulation of the storage room. [Brief explanation of the drawing]
[0007] [Figure 1] Perspective view of the storage facility in Embodiment 1 [Figure 2] Plan view of the opposite side of the storage room door, seen from above. [Figure 3] Plan view of the sealing member on one side of the storage room door, seen from above. [Modes for carrying out the invention]
[0008] (Knowledge and other information that formed the basis of this disclosure) At the time the inventors conceived of this disclosure, there was a technology, as described in Patent Document 1, in which a pair of doors arranged in the left-right direction were each equipped with a sealing member, and the gap between the pair of doors was sealed by the close contact of magnet housings formed in the sealing members. However, the inventors discovered that the conventional technology did not take into account the phenomenon in which one magnet housing deforms to approach the other magnet housing, causing the two magnet housings to overlap in the front-to-back direction, and in order to solve this problem, they came to constitute the subject matter of this disclosure. Therefore, this disclosure provides a storage unit that can improve the thermal insulation of the storage room by making it easier to close a pair of doors by moving one magnet housing away from the other magnet housing.
[0009] The embodiments will be described in detail below with reference to the drawings. However, some unnecessarily detailed explanations may be omitted. For example, detailed explanations of already well-known matters or redundant explanations of substantially identical configurations may be omitted. 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.
[0010] (Embodiment 1) Embodiment 1 will be described below with reference to Figures 1 to 3. In each figure, the symbol FR indicates the front of the storage unit 1 in its installed state, the symbol UP indicates the top of the storage unit 1, and the symbol LH indicates the left side of the storage unit 1. In the following description, each direction is a direction along these directions of the storage unit 1. In the following description, the surface on which the opening 2B is provided is referred to as the front, and the direction in which this front faces is referred to as the front. In addition, the direction along the vertical direction in the installed state of the storage unit 1 is referred to as the up-down direction, and the directions along the horizontal direction are referred to as the front-back direction and the left-right direction.
[0011] [1-1. Structure] [1-1-1. Storage Room Configuration] Figure 1 is a perspective view of a storage unit 1 according to an embodiment of the present invention. Figure 2 is a plan view of the opposing section 20 seen from above. Storage unit 1 is a vertical refrigerator, as shown in Figure 1. Storage unit 1 comprises a storage unit body 2, multiple doors 4, and a machine room 6.
[0012] 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 provided in the space between the outer box 5 and the inner box 7. The storage unit body 2 is a box-shaped structure equipped with an insulating wall formed by filling the space enclosed by the outer box 5 and the inner box 7 with insulating material. In this embodiment, both the outer box 5 and the inner box 7 are made of metal such as stainless steel plates. The insulating material used is polystyrene foam or rigid polyurethane foam.
[0013] The storage unit body 2 has a storage chamber 2A inside, and a rectangular opening 2B is provided on the front when viewed from the front. The plane including the front where the opening 2B is provided is called the opening surface P. On the opening surface P of the storage body 2, an opening edge portion 2C is provided that surrounds the opening 2B over the entire circumference. The opening edge portion 2C has a plane that is located on substantially the same plane as the opening surface P of the storage body 2. In the storage body 2, a partition body 2D for partitioning the opening 2B is provided. The partition body 2D is a beam-shaped member that extends in the left-right direction. The partition body 2D is formed in a box shape made of metal and is configured by filling heat insulating material 8 inside. Each of both ends of the partition body 2D is connected to an intermediate portion in the up-down direction of each of the opening edge portions 2C located in the left-right direction.
[0014] Note that the outer box 5 and the inner box 7 may be formed not only of metal but also 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 a hard resin. Also, for example, the storage body 2 may be formed by combining a heat insulating wall formed by forming a plate-like member such as a steel plate into a housing shape and filling heat insulating material 8 inside the housing.
[0015] The machine room 6 is arranged above the storage body 2. Inside the machine room 6, a refrigeration device 81 that constitutes a refrigeration cycle is housed. More specifically, the refrigeration device 81 includes a compressor 82, a condenser 83, a condenser blower 84, a capillary tube 85, an electric box 86, and an evaporator 87. By driving these, cold air is sent into the storage room 2A. In the present embodiment, the evaporator 87 is provided inside the storage body 2. Note that the capillary tube 85 may be another throttling mechanism such as a throttle valve.
[0016] The plurality of doors 4 are rectangular door members that can open and close the opening 2B of the storage body 2. The storage 1 of the present embodiment is provided with two sets of a pair of doors 4 arranged in the left-right direction, one set above and one set below. Each of the doors 4 has one set above the partition body 2D and one set below the partition body 2D with the partition body 2D interposed therebetween.
[0017] These doors 4 are arranged with one side adjacent to the other. Each of the pair of doors 4 can be opened and closed to the left and right of the storage room 1 by a hinge 11. The pair of doors 4 are so-called double doors.
[0018] On the front of door 4, a handle 18 is provided at a position that is close to the adjacent opposing surface 4B in the left-right direction. The following describes one door 4, but the other doors 4 have a similar structure. As shown in Figure 2, door 4 is a flat plate-shaped member having a predetermined thickness. Door 4 comprises a door body 12 and a plurality of body sealing members 13.
[0019] The rear surface of the door body 12 is made up of a door interior panel 14 made of hard resin. The interior of these door bodies 12 is filled with insulating material 8 such as expanded polystyrene or rigid polyurethane foam (see Figure 2).
[0020] The main sealing member 13 is a sealing member such as a packing or gasket, formed from a soft resin such as rubber or soft polyvinyl chloride, and capable of elastic deformation. In this embodiment, the main sealing member 13 is formed in a rectangular shape, and each is attached to the groove shape described above, so that it is arranged in a frame-like manner on the door body 12.
[0021] The main sealing member 13 is formed in a hollow shape with a space inside. Four rod-shaped magnets are housed in the internal space of the main sealing member 13, extending circumferentially. Each of these magnets has a length approximately equal to that of each side of the rear surface of the door body 12. Each of the magnets is inserted into the internal space of the main sealing member 13 along each side of the main sealing member 13.
[0022] [1-1-2. Configuration of mounting components] Figure 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 the opposing section 20. At the position of the opposing section 20 of the doors 4, a sealing member 50 that closes the gap between the pair of doors 4 and a mounting member 30 to which the sealing member 50 can be attached are arranged. The mounting member 30 is provided on the opposing surface 4B, which is the surface of the doors 4 located in the opposing section 20.
[0023] The mounting member 30 is formed from a rigid resin as a rigid material. This mounting member 30 is a long member having a length approximately the same as the opposing surface 4B of the door 4. The mounting member 30 is a plate-shaped member formed, for example by extrusion molding, so that its end face is C-shaped.
[0024] The mounting member 30 includes a flat base portion 31 that extends along the entire longitudinal direction of the mounting member 30. The base portion 31 is mounted so that its longitudinal direction aligns with the vertical direction of the door 4, and its thickness direction aligns with the left-right direction. The width dimension of the mounting member 30, which is the dimension along the front-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 by a fastening member 32.
[0025] As shown in Figure 2, a front locking piece 33 is formed at the front end of the door 4 on the base portion 31. The front locking piece 33 is formed to protrude from the base portion 31 toward the opposing surface 4B of the other door 4. The tip of the front locking piece 33 is formed in a curved claw shape toward the front side of the door 4. The front locking piece 33 engages with a second cover locking piece 60 provided by the cover portion 52, which will be described later.
[0026] A central engaging piece 34 is formed approximately in the center of the base portion 31 in the front-rear direction. The central engaging piece 34 is formed to protrude from the base portion 31 toward the opposing surface 4B of the other door 4. In a plan view, the tip of the central engaging piece 34 is bent in an L-shape toward the storage body 2. A first cover engaging piece 59, provided by the cover portion 52 which will be described later, engages with this central engaging piece 34.
[0027] At the base portion 31, a first heater holding portion 37 for holding the heater 36 is formed at the end on the storage body 2 side of the central engaging piece 34. The first heater holding portion 37 is formed in a groove shape that is open at the front and recessed towards the rear. In the front-rear direction of the storage compartment 1, the first heater holding portion 37 is positioned approximately the same as the outer peripheral edge 12A of the rear surface of the door body 12, or on the front side of the door 4 than the outer peripheral edge 12A.
[0028] As shown in Figure 2, an extended portion 35 is formed on the base portion 31. The extended portion 35 extends from the rear end of the first heater holding portion 37 toward the storage chamber 2A and also extends along the rear surface of the door 4, and abuts against the outer peripheral edge 12A of the rear surface of the door body 12 to which the mounting member 30 is attached. Therefore, when the mounting member 30 is attached to the door 4, the base portion 31 abuts against the opposing surface 4B of the door 4, and the extended 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. As a result, the mounting member 30 can be easily attached to the opposing surface 4B of the door 4 while suppressing misalignment. The extended portion 35 is positioned so that its entirety is closer to the storage body 2 than the rear surface of the door 4 and the outer peripheral edge 12A.
[0030] The extended portion 35 has a second heater holding portion 38 that can hold the heater 36. The second heater holding portion 38 is formed in a groove shape that is open on the side facing the opposing portion 20 and recessed toward the side facing the main body sealing member 13.
[0031] A receiving portion 39 is formed on the extended portion 35 on the back side of the second heater holding portion 38, that is, on the side opposite to the opposing portion 20. The locking portion 40 of the receiving portion 39 is formed substantially perpendicular to the opening surface P. Furthermore, the receiving portion 39 is formed to match the shape of the locking portion 67 provided by the biasing member 65, which will be described later. A slit-shaped opening is formed in the receiving portion 39 on the side opposite to the opposing portion 20. The locking portion 40 and the slit-shaped opening form the receiving portion 39 in a substantially T-shape.
[0032] The extended portion 35 has a restricting portion 41 that extends towards the rear. The restricting portion 41 is formed at the position furthest from the opposing portion 20 on the extended portion 35. When viewed from above or below, the restricting portion 41 is formed in a roughly T-shape.
[0033] A flat portion 42 is formed at the rear tip of the restricting portion 41. The flat portion 42 has a flat plate shape and is positioned opposite the opening surface P. The rear end surface of the flat portion 42 forms a plane that is substantially parallel to the opening surface P. The flat portion 42 is provided with a stopper portion 43 that protrudes toward the opposing portion 20. The stopper portion 43 is formed to protrude toward the opposing portion 20 more than the plate-shaped member that extends in the front-rear direction of the restricting portion 41.
[0034] The flat portion 42 provides a flat surface on the mounting member 30 that, when viewed from the storage unit body 2 side, closes off a portion of the opening 2B. As a result, in the storage unit 1, air from the storage chamber 2A leaks out to the outside of the storage unit 1, and air from outside the storage unit 1 enters the storage chamber 2A.
[0035] The flat portion 42 is positioned at a predetermined distance from the main sealing member 13 in the left-right direction. This prevents the flat portion 42 from hindering the deformation of the main sealing member 13, even when the main sealing member 13 deforms in close contact with the storage unit body 2 in the storage unit 1. The extended portion 35 has a second restricting portion 41A that extends 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 member] Figure 3 is a plan view of the sealing member 50 of the right-hand door, seen from above. Figure 3 shows the upper end face of the sealing member 50.
[0037] As shown in Figures 2 and 3, the sealing member 50 comprises a side packing 51, a cover portion 52, and a front fin portion 53, which are formed by integrally molding them. The sealing member 50 is a long, plate-like member with a length similar to that of the mounting member 30, and the entire structure is molded so that the end face is C-shaped. The sealing member 50 is installed so that its longitudinal direction is aligned with the vertical direction of the door 4.
[0038] The rear of the sealing member 50 is formed by a side packing 51. The side packing 51 is positioned opposite the opening 2B. The side packing 51 functions as a member that seals the opposing portion 20 to prevent cold 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] As shown in Figures 2 and 3, the magnet housing 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 and is provided along the entire longitudinal direction of the side packing 51. The contact portion 54 is integrally formed with the side packing 51.
[0040] The contact surfaces of the contact portion 54 on the opposing portion 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. The magnet 57 is positioned to be in contact with the back side of the contact surface of the contact portion 54.
[0041] The contact portion 54 includes an extension portion 58 that extends from the magnet housing portion 56 to the front side of the door 4. The extension portion 58 has a plane continuous with the contact surface and is bent at a predetermined angle relative to the contact surface in a direction away from the other door 4 facing it. A connecting portion 55 is attached to the front end of the extension portion 58. A cover portion 52 is attached to the front end of the connecting portion 55.
[0042] The cover portion 52 is made of a hard resin, which is a harder material than the adhesive portion 54. As shown in Figure 3, the cover portion 52 is molded into a plate shape with a C-shaped end face.
[0043] A first cover engagement piece 59 is formed at the rear end of the cover portion 52. This first cover engagement piece 59 protrudes toward the door body 12 to which the sealing member 50 is attached. The tip of the first cover engagement piece 59 is formed in a claw shape. As described above, the cover engagement piece 59 engages with the central engagement piece 34.
[0044] A second cover locking piece 60 is formed at the front end of the cover portion 52. The second cover locking piece 60 is formed to protrude toward the door 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 protrudes toward the storage body 2. As described above, the front locking piece 33 engages with the second cover locking piece 60.
[0045] A front fin portion 53 is integrally formed at the front tip of the second cover locking piece 60. This front fin portion 53, like the side packing 51, is made of a soft material such as rubber or other soft resin. The front fin portion 53 is formed 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, which is an elastically deformable material such as rubber or soft polyvinyl chloride. The side packing 51 is an elastically deformable component. The side packing 51 has an L-shaped end face, and a magnet housing portion 56 is provided at the corner of the L-shape, with the end face partitioned to form a rectangular space.
[0047] A rod-shaped magnet 57 is inserted through the magnet housing 56. One magnetic pole of the magnet 57 is positioned on the storage unit body 2 side, and the other magnetic pole is positioned on the front side of the door 4. The magnets 57 provided on each of the pair of doors 4 are positioned such that, when the pair of doors 4 are closed, adjacent magnetic poles are opposite to each other in the left-right direction. In other words, in the pair of doors 4, the magnet 57 provided on one door 4 is inserted through the magnet housing 56 such that the arrangement of the magnetic poles is reversed in the front-rear direction compared to the arrangement of the magnetic poles of the magnet 57 provided on the other door 4.
[0048] The side packing 51 includes a first sealing portion 61. The first sealing portion 61 is continuous with the surface of the magnet housing portion 56 facing the storage container body 2 and has a flat plate shape that extends in the left-right direction and in a direction away from the magnet housing portion 56. As shown in Figures 2 and 3, at least the surface of the first sealing portion 61 facing the storage container body 2 is arranged substantially parallel to the opening surface P of the storage container body 2. The first sealing portion 61 corresponds to the "sealing portion" in this disclosure.
[0049] As shown in Figure 3, the first sealing portion 61 has an inner fin portion 62 formed on the opposite side of the magnet housing portion 56. As shown in Figure 2, the inner fin portion 62 extends toward the main body sealing member 13 and has a fin shape at its tip that abuts against the main body sealing member 13.
[0050] As shown in Figure 2, when the door 4 is closed, the first sealing 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 sealing portion 61 and the inner fin portion 62 may be subjected to pulling operations that move them 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 chamber 2A. Therefore, the inner fin portion 62 is affected by temperature changes as the door 4 is opened and closed.
[0051] In this embodiment, the inner fin portion 62 is formed by bending at a shallow angle at multiple points in the middle of the left-right direction toward the main body sealing member 13, or in other words toward the door 4. As a result, even when the first seal portion 61 and the inner fin portion 62 are subjected to operations such as cleaning or temperature changes, irregular deformation such as separation from the main body sealing member 13 is suppressed. Therefore, in the storage unit 1, when the door 4 is closed, a gap is suppressed between the storage unit body 2 and the door 4.
[0052] As shown in Figures 2 and 3, a second seal portion 63 is provided in the middle of the first seal portion 61 in the left-right direction. This second seal portion 63 is formed to protrude rearward from a position between the end face of the magnet housing portion 56 opposite to 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 housing portion 56. The end face of the second seal portion 63 is formed to be L-shaped.
[0053] The tip of the second sealing portion 63 is formed to extend in the left-right direction to a position approximately the same as the surface located on the other door 4 side of the magnet housing portion 56.
[0054] As shown in Figure 3, a biasing member 65 is provided in the middle of the first sealing portion 61 in the left-right direction. The biasing member 65 extends in a substantially straight line when viewed from above toward the front side of the storage compartment 1, in other words toward the rear side of the door 4. The biasing member 65 has a shaft portion 66 that is formed in a flat plate shape in the front-rear direction. The shaft portion 66 is formed to extend substantially perpendicular to the opening surface P. The base portion 68, which constitutes the rear end of the biasing member 65, is positioned further away from the root of the second sealing portion 63 as viewed from the opposing portion 20. The base portion 68 corresponds to the "base" in this disclosure. Although the biasing member 65 is formed integrally with the first sealing portion 61, it may also be joined together.
[0055] The tip of the biasing member 65 is provided with a locking portion 67 whose end face is formed in a substantially T shape. As shown in Figure 2, the locking portion 67 is inserted into a receiving portion 39 provided on the mounting member 30.
[0056] The biasing member 65 is made of a rubbery resin. As shown in Figure 3, the biasing member 65 is not molded with its shaft portion 66 pre-bent. As shown in Figure 2, when the biasing member 65 is attached to the door 4, it is bent to the opposing portion 20 side at an angle of approximately 60 to 120 degrees.
[0057] As a result, the biasing member 65 is elastically deformed, and when 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 Figure 3.
[0058] Due to the elastic force, the locking portion 67 is locked to the receiving portion 39, and a force acts on the first sealing portion 61 in a direction away from the opposing portion 20 via the base portion 68 of the biasing member 65. Since the first sealing portion 61 and the magnet housing portion 56 are formed integrally, the elastic force causes stress to act on the magnet housing portion 56 in a direction away from the opposing portion 20.
[0059] Furthermore, each part 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 all made of the same resin material. Therefore, these 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, can be easily joined together. As a result, 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 can be easily formed as a single unit, and the sealing member 50 can be easily manufactured.
[0060] [1-2. Operation] When the door 4 comes into contact with the storage unit body 2, the sealing members 50 of the pair of doors 4 are attracted to each other by the magnetic force of the magnet 57. The contact portions 54 of the two sealing members 50 come into close contact with each other, and the opposing portions 20 are closed. Figure 2 shows the state in which the sealing member 50 on the right deforms and adheres to the sealing member 50 on the left.
[0061] When the right door 4 is opened from the state shown in Figure 2, the elastic force of the biasing member 65, which is generated as the shaft portion 66 attempts to return to the state shown in Figure 3, causes the magnet housing portion 56 to move away from the opposing portion 20. This prevents the two magnet housing portions 56 from overlapping in the front-to-back direction when the right door 4 is closed.
[0062] Furthermore, if the magnet housing 56 moves too far away from the opposing portion 20 due to the elastic force of the biasing member 65, there is a risk that the distance between the two magnets 57 will become too large. In this case, when closing the other door 4 with one door 4 closed, the contact portions 54 may not make close contact with each other, and the opposing portion 20 may not be closed. In this embodiment, since the stopper portion 43 of the restricting portion 41 is formed in a direction away from the opposing portion 20 than the base portion 68 of the biasing member 65, the base portion 68 does not move in a direction away from the opposing portion 20 than the stopper portion 43. In other words, the phenomenon of the magnet housing 56 moving too far away from the opposing portion 20 can be suppressed by the stopper portion 43. As a result, the phenomenon in which the distance between the two magnets 57 becomes too large, the contact portions 54 do not make close contact with each other, and the opposing portion 20 is not closed can be suppressed.
[0063] Furthermore, the shape of the end of the second restricting portion 41A or the second heater holding portion 38 on the magnet housing portion 56 side may be modified to suppress the phenomenon of the magnet housing portion 56 moving too far away from the opposing portion 20. For example, the end of the second restricting portion 41A on the opposing portion 20 side shown in Figure 2 may be formed to extend further toward the magnet housing portion 56 side. Also, for example, the end of the second heater holding portion 38 on the opposing portion 20 side shown in Figure 2 may be formed to extend further toward the magnet housing portion 56 side. In this case, if the magnet housing portion 56 moves too far away from the opposing portion 20 due to the elastic force of the biasing member 65, the second restricting portion 41A or the second heater holding portion 38 can contact the magnet housing portion 56, thereby restricting the movement of the magnet housing portion 56.
[0064] In the pair of doors 4, the magnet 57 provided on one door 4 is positioned so that the arrangement of its magnetic poles is reversed in the front-to-back direction compared to the arrangement of the magnetic poles of the magnet 57 provided on the other door 4. Therefore, when closing the other door 4 with one door 4 closed, the magnet housing 56 of the other door 4 moves away from the opposing part 20 due to magnetic repulsion. However, if the closing speed of the other door 4 is large, for example, if the other door 4 is closed forcefully, the magnet housing 56 does not move due to magnetic repulsion. In this embodiment, a biasing member 65 constantly exerts stress on the magnet housing 56 in the direction away from the opposing part 20.
[0065] Furthermore, the stress exerted by the elastic force of the biasing member 65 in the direction that causes the magnet housing portion 56 to move away from the opposing portion 20 is configured to be weaker than the attractive force between the two magnets 57. In other words, the biasing member 65 is configured such that the elastic force prevents the contact portions 54 from coming into close contact with each other and prevents the opposing portion 20 from being blocked.
[0066] [1-3. Effects, etc.] As described above, the storage unit 1 in this embodiment comprises a storage unit body 2 having a storage chamber 2A, and a double-opening door 4 that closes the opening surface P including the opening 2B of the storage unit body 2. The door 4 comprises a mounting member 30 provided on the opposing portion 20 side of each door 4, and a sealing member 50 attached to the mounting member 30. The sealing member 50 comprises a first sealing portion 61 (seal portion) facing the opening surface P, and the first sealing portion 61 comprises a magnet housing portion 56 and a biasing member 65 erected toward the door 4 from a point facing the storage chamber 2A when the door 4 is closed. The mounting member 30 has a receiving portion 39 located closer to the opposing portion 20 than the base portion 68 of the biasing member 65, and the tip of the biasing member 65 is locked to the receiving portion 39 by elastic deformation. In this configuration, the elastic force of the biasing member 65 causes stress to act on the first seal portion 61 via the base portion 68, and stress acts on the magnet housing portion 56 formed in the first seal portion 61 in a direction away from the opposing portion 20. Therefore, by moving one magnet housing portion 56 away from the other magnet housing portion 56, the pair of doors 4 become easier to close. Thus, the thermal insulation of the storage room 2A can be improved.
[0067] Alternatively, the receiving portion 39 may bend the biasing member 65 in a direction substantially perpendicular to the protruding direction of the base portion 68 to support the tip of the biasing member 65. With this configuration, by locking the locking portion 67 into the receiving portion 39, the shaft portion 66 bends, generating an elastic force in the biasing member 65.
[0068] Furthermore, the biasing member 65 includes a shaft portion 66 formed in the shape of a flat plate protruding from the base portion 68, and a locking portion 67 formed at the tip of the shaft portion 66 substantially perpendicular to the shaft portion 66, and the receiving portion 39 includes 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. With this configuration, by engaging the locking portion 67 with the receiving portion 39, the shaft portion 66 bends, generating an elastic force in the biasing member 65. Furthermore, by engaging the locking portion 67 with the receiving portion 39, the shaft portion 66 bends at approximately a right angle, generating a greater elastic force than if the shaft portion 66 were bent at an acute angle.
[0069] Furthermore, the mounting member 30 may include a restricting portion 41 that is erected toward the opening surface P at a position further from the opposing portion 20 than the base portion 68 of the biasing member 65. With this configuration, when the base portion 68 comes into contact with the restricting portion 41, the magnet housing portion 56 will not move any further due to the elastic force of the biasing member 65. This allows the restricting portion 41 to define the amount of movement of the magnet housing portion 56 in the direction away from the opposing portion 20.
[0070] (Other embodiments) As described above, Embodiment 1 has been presented as an example disclosed in this application. However, the technology in this disclosure is not limited to this and can be applied to embodiments that have been modified, replaced, added, or omitted. Furthermore, it is possible to combine the components described in Embodiment 1 to create new embodiments. Therefore, other embodiments are described below as examples.
[0071] The locking portion 67 is configured with an end face that is roughly T-shaped, but its shape is not limited. The locking portion 67 only needs to be formed so as to be able to lock onto the receiving portion 39, and may be formed in the shape of an arc, or in the shape of a claw 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 appropriately changed according to the shape of the locking portion 67.
[0072] The receiving portion 39 only needs to be positioned 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 exert stress on the magnet housing portion 56 in a direction away from the opposing portion 20. The elastic force of the biasing member 65 can be adjusted as appropriate, for example, by changing the hardness of the resin or by changing the thickness of the shaft portion 66.
[0073] Since the embodiments described above are for illustrative purposes of the technology described herein, various modifications, substitutions, additions, omissions, etc., can be made within the claims or their equivalents.
[0074] (Note) Based on the above description of embodiments, the following technologies are disclosed.
[0075] (Technical 1) A storage facility comprising a storage body having a storage room, and a double-hinged door that closes the opening surface including the opening of the storage body, wherein each door comprises a mounting member provided on the opposing side of the door, and a sealing member attached to the mounting member, the sealing member comprising a sealing portion facing the opening surface, the sealing portion comprising a magnet housing portion and a biasing member erected toward the door from a point facing the storage room when the door is closed, the mounting member comprising a receiving portion located closer to the opposing portion than the base of the biasing member, and the tip of the biasing member being elastically deformed to engage with the receiving portion, the storage facility. In this configuration, the elastic force of the biasing member causes stress to act on the seal portion via the base, and this 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, the pair of doors can be closed more easily. Thus, the thermal insulation of the storage room can be improved.
[0076] (Technical 2) The storage container according to Technical 1, wherein the receiving portion bends the biasing member in a direction substantially perpendicular to the protruding direction of the base to support the tip of the biasing member. With this configuration, by engaging the locking part with the receiving part, the shaft part can bend, generating an elastic force in the biasing member.
[0077] (Technical 3) The storage container according to Technical 2, wherein the biasing member comprises a flat plate-shaped shaft portion protruding from the base portion, and a locking portion formed substantially perpendicular to the shaft portion at the tip of 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 part with the receiving part, the shaft bends, generating an elastic force in the biasing member. Furthermore, by engaging the locking part with the receiving part, the shaft bends at approximately a right angle, generating a greater elastic force than if the shaft were bent at an acute angle.
[0078] (Technical 4) The storage container according to any one of Technical 1 to 3, wherein the mounting member comprises a restricting portion erected toward the opening surface at a position further away from the opposing portion than the base portion. With this configuration, when the base comes into contact with the restricting portion, the magnet housing portion will not move any further due to the elastic force of the biasing member. This allows the amount of movement of the magnet housing portion away from the opposing portion to be defined by the restricting portion. [Industrial applicability]
