[0008] (The knowledge and other information that formed the basis of this disclosure) At the time when the inventors came up with the present disclosure, there was a technology for a storage facility having a door body at the opening of the storage facility main body, the storage facility main body being formed by sandwiching a heat insulating material between an outer plate and an inner plate, and the outer plate and the inner plate being connected by a connecting member. However, when a heater is arranged at a position facing the vicinity of the outer edge sealing member of the door body at the opening of the storage facility main body, a deviation occurs in the arrangement position of the heater, and due to this deviation, there is a risk that heat cannot be effectively transferred to the outer edge sealing member of the door body, and in this case, the inventors discovered a problem that the power consumption of the heater increases, and in order to solve this problem, they came to constitute the subject of the present disclosure. Therefore, the present disclosure provides a storage facility that can position a heater in an appropriate location and reduce power consumption.

[0009] (Embodiment 1) [1-1. Configuration] Hereinafter, the embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanations than necessary may be omitted. For example, detailed explanations of already well-known matters or duplicate explanations of substantially the same configurations may be omitted. 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.

[0010] FIG. 1 is a perspective view of a storage cabinet 1 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of a door 4. FIG. 3 is a cross-sectional view taken along plane III in FIG. 1. FIG. 3 is a view seen from above downward, with part of side walls 131 and 132 omitted. FIG. 4 is an enlarged cross-sectional view showing the right end of FIG. 3. FIG. 5 is a cross-sectional view of a connecting member 9 shown in FIG. 4. The symbol FR shown in each figure indicates the front of the storage cabinet 1 in the installed state, the symbol UP indicates the upper side of the storage cabinet 1, and the symbol LH indicates the left side of the storage cabinet 1. In the following description, each direction is along the direction of these storage cabinets 1. 1, the storehouse 1 includes a storehouse main body 2, a plurality of doors 4, and a machine room 6. The door 4 corresponds to an example of a door body. The storage body 2 is a box having an insulating wall 3. The insulating wall 3 is composed of a pair of side walls 131, 132, an upper wall 133, a lower wall 134, and a back wall 135. The partition walls 131-135 are all formed in a panel shape. The storage body 2 is formed by assembling the partition walls 131-135. Each of the partition walls 131-135 is formed by filling a space surrounded by an outer plate 5 and an inner plate 7 with an insulating material 8. The outer plate 5 and the inner plate 7 are both formed of a metal such as a stainless steel plate, and the insulating material 8 is made of polystyrene foam, hard urethane foam, or the like. The outer plate 5 and the inner plate 7 are not limited to metal, and may be formed of hard resin such as ABS resin. The outer plate 5 and the inner plate 7 may be formed by combining metal and hard resin. Although the storage container body 2 is formed by assembling the partition walls 131-135, the storage container body 2 may be formed by placing a box-shaped inner box inside a box-shaped outer box, with a heat insulating material sandwiched between the outer box and the inner box. The storage body 2 has a storage chamber 2A provided therein and an opening 2B provided on the front side.

[0011] As shown in FIG. 1, the multiple doors 4 are rectangular door members capable of closing the opening 2B of the storage body 2. The storage 1 of this embodiment is provided with two pairs of doors 4 arranged in the left-right direction, one above the other, and these doors 4 are arranged with one side adjacent to each other. In addition, hinges 11 are provided on the upper and lower surfaces of each door 4 at locations located on the other side of each door 4. Each pair of doors 4 can be opened and closed in the left-right direction of the storage 1 by these hinges 11. In other words, each pair of doors 4 is a double door. Further, on the front surface of each door 4, a handle 18 is provided on each side surface adjacent to each other in the left-right direction.

[0012] The door 4 is a flat plate-like member having a predetermined thickness, as shown in Figures 1, 2, and 3. The door 4 includes a door body 12 and a plurality of outer edge sealing members 50, as shown in Figure 3. The front, both sides, top, bottom, and rear outer edge of the door body 12 are all formed as a single unit from a metal such as a stainless steel plate, and the door exterior plate 13 is formed as a single unit. The center of the rear of the door body 12 is formed as an interior door plate 14 made of a hard resin. The center of this interior door plate 14 protrudes further into the storage chamber 2A than the outer edge of the rear of the door body 12.

[0013] As shown in FIG. 3, the space surrounded by the door exterior plate 13 and the door interior plate 14 is filled with a heat insulating material 15 such as polystyrene foam or hard urethane foam. 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.

[0014] The multiple outer edge sealing members 50 are sealing members called packings or gaskets made of soft resin such as rubber or soft polyvinyl chloride. Each of these outer edge sealing members 50 is formed in a linear shape so as to correspond to each side of the outer edge of the door body 12.

[0015] An outer edge magnet housing portion 52 having a rectangular cross section is provided at a corner portion 50A of the outer edge sealing member 50, and a rod-shaped outer edge magnet 51 is housed inside the outer edge magnet housing portion 52. The outer edge magnets 51 have a length approximately equal to each side of the rear surface of the door main body 12, and are inserted into each outer edge magnet housing portion 52 along each side.

[0016] As shown in Fig. 1, the machine room 6 is disposed above the storage body 2. A refrigeration device 61 constituting a refrigeration cycle is housed inside the machine room 6. In more detail, 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.

[0017] 3 and 4, the outer plate 5 has a front edge 5A that corresponds to the front surface of the storage facility 1, and a side edge 5B at a position that corresponds to the inside of the opening 2B. That is, the outer plate 5 has a folded portion 5X that is bent at the position of the opening 2B toward the inside surface of the opening, forming a substantially L-shaped cross section. The folded portion 5X is composed of the front edge 5A, the side edge 5B, and a folded body 5C. The front edge 5A corresponds to the front frame of the storage facility 1.

[0018] The tip of the side edge 5B is folded to form a folded body 5C. The folded body 5C is formed at the end of the folded portion 5X, i.e., the end of the side edge 5B, so as to be bent at an acute angle toward the inner surface of the folded portion 5X, i.e., the back surface of the front edge 5A. The inner plate 7 has an end 7A formed approximately horizontally.

[0019] As shown in Fig. 1, the inner surface of the opening 2B is formed by a resin connecting member 9. The connecting member 9 is a member that connects the outer plate 5 and the inner plate 7 at the opening 2B. The connecting member 9 also serves to close the gap between the outer plate 5 and the inner plate 7, i.e., the gap between the end portion 7A and the folded-back body 5C. The connecting member 9 is provided on each of the four sides that form the entire periphery of the opening 2B.

[0020] 3, 4, and 5, the connecting member 9 includes an outer member 21 exposed on the inner surface of the opening 2B, an inner member 25 on the inside of the outer plate 5 and the inner plate 7, and a pillar portion 23 connecting the outer member 21 and the inner member 25. The pillar portion 23 is formed substantially perpendicular to the outer member 21. The outer member 21 includes a front half portion 21F extending toward the opening 2B side and a rear half portion 21B extending toward the rear wall 134 side. The inner member 25 includes a front half portion 25F extending toward the opening 2B side and a rear half portion 21B extending toward the rear wall 134 side.

[0021] The rear half 21B of the outer member 21 is formed with two projections, a third projection 41A and a fourth projection 41B, which come into contact with the end 7A of the inner plate 7. Hereinafter, the third projection 41A and the fourth projection 41B will be simply referred to as projections 41A and 41B. The rear half 25B of the inner member 25 is formed with a pressing portion 27 which is bent so as to come into contact with the end 7A of the inner plate 7. The connecting member 9 holds the inner plate 7 by sandwiching the end 7A of the inner plate 7 between the pressing portion 27 and the third projection 41A and the fourth projection 41B of the rear half 21B of the outer member 21.

[0022] The front half 21F of the outer member 21 is formed with two projections, a first projection 39A and a second projection 39B, which contact the side edge 5B. Hereinafter, the first projection 39A and the second projection 39B are simply referred to as projections 39A and 39B. The front half 21F of the outer member 21 is also formed with a positioning projection 37, which contacts the apex 5Cb of the folded-back body 5C of the outer plate 5 and is higher than the projections 39A and 39B. The projections 39A, 39B, and the positioning projection 37 are positioned in this order from the front to the rear of the storage shed 1. The projections 39A, 39B, and the positioning projection 37 are formed substantially perpendicular to the outer member 21.

[0023] An engagement portion 29 with which the folded body 5C of the outer plate 5 engages is formed in the front half 25F of the inner member 25. The engagement portion 29 has an inclined guide portion 29A and a stopper portion 29B continuous with the inclined guide portion 29A. The folded body 5C is guided by the inclined guide portion 29A, and the tip portion 5Ca of the folded body 5C abuts against the stopper portion 29B of the engagement portion 29. The folded body 5C may also abut against the inclined guide portion 29A.

[0024] As shown in Figs. 4 and 5, a gripping portion 31 for gripping the heater 45 and an inner surface abutting portion 35 for abutting the inner surface of the bent portion 5X of the outer plate 5 are formed at the tip of the front half 25F of the inner member 25. The gripping portion 31 for gripping the heater 45 is formed with an inner side recessed in a substantially semicircular shape. As shown in Fig. 5, the gripping portion 31 is connected to the engaging portion 29 side of the front half 25F of the inner member 25 at an obtuse angle via a bent portion 33. Then, as shown in Fig. 4, when the outer plate 5 and the inner plate 7 are connected with the connecting member 9, the bent portion 33 is bent at a substantially right angle, the connecting strength between the outer plate 5 and the inner plate 7 is increased, and the gripping portion 31 is pressed against the inner surface side of the leading edge portion 5A, so that the heater 45 is positioned at an appropriate position of the leading edge portion 5A of the outer plate 5.

[0025] The appropriate position is a position where the heater 45 faces the outer edge sealing member 50 of the door 4 when the storage cabinet 1 is viewed from the front. In this case, the heater 45 is positioned offset by a predetermined width W1 toward the outside of the storage cabinet 1 from the position of the corner 50A of the outer edge sealing member 50. The heater 45 suppresses condensation on the front edge 5A of the outer panel 5 around the opening 2B of the storage cabinet 1, the door 4, the outer edge sealing member 50, the front edge 5A, etc., but by positioning the heater 45 offset by the predetermined width W1, heating of the outer edge magnet 51 is suppressed, and the power consumption of the heater 45 is reduced.

[0026] The gripping portion 31 has a cross section formed in a substantially semicircular shape, is open at the front, and is formed so that the semicircular cutout 31A faces the back surface of the front edge portion 5A. The heater 45 is sandwiched between the gripping portion 31 and the inner surface of the bent portion 5X, i.e., the front edge portion 5A. Furthermore, an inner surface abutment portion 35 is formed on the tip side of the inner member 25 relative to the bent portion 33. The inner surface abutment portion 35 abuts against the inner surface of the bent portion 5X, i.e., the back surface of the front edge portion 5A. This stabilizes the position of the gripping portion 31, suppresses deviation of the position of the heater 45, and reduces the power consumption of the heater 45.

[0027] As shown in Fig. 4, the storage body 2 has a first space R1 surrounded by the folded body 5C and the front half 25F of the inner member 25, a second space R2 surrounded by the outer member 21, the pillar portion 23, the inner member 25, and the folded body 5C, and a third space R3 surrounded by the rear half 21B of the outer member 21, the pillar portion 23, and the pressing portion 27. As shown in Fig. 5, each connecting member 9 has at least one through hole 43 formed between the pillar portion 23 and the engaging portion 29. That is, the through hole 43 is provided in the second space R2.

[0028] The first space R1 is not filled with the insulating material 8 unless the insulating material 8 expands and enters the gap between the outer plate 5 and the inner surface abutting portion 35. The third space R3 is not filled with the insulating material 8 unless the insulating material 8 expands and enters the gap between the inner plate 7 and the pressing portion 27.

[0029] The heat insulating material 8 is filled in the space surrounded by the outer plate 5, the inner plate 7, and the gripping portion 31. This causes the heat insulating material 8 to apply a force pressing the gripping portion 31 against the back surface of the leading edge portion 5A, making it easier for the heater 45 and the leading edge portion 5A to come into contact with each other.

[0030] [1-2. Effects, etc.] When the insulating material 8 is filled in the space surrounded by the outer plate 5 and the inner plate 7, the space becomes high pressure, and the foaming insulating material 8 pushes the front edge portion 5A from the inside to the outside. Referring to FIG. 3, the folded body 5C abuts against the engagement portion 29. As a result, when a force from the inside to the outside of the outer plate 5 acts on the front edge portion 5A, the folded body 5C is caught by the engagement portion 29, so that the deformation of the front edge portion 5A toward the front of the storage facility 1 can be suppressed. In addition, since the folded body 5C is formed at an acute angle, when a force from the inside to the outside of the outer plate 5 acts on the front edge portion 5A, the folded body 5C is unlikely to deform. Furthermore, the inclined guide portion 29A can suppress the deformation of the folded body 5C.

[0031] Furthermore, when the insulating material 8 foams, it can escape toward the second space R2 through the through hole 43 of the inner member 25 shown in Figure 5, thereby preventing deformation of the front edge portion 5A and leakage of the insulating material 8 to the outside of the storage facility 1.

[0032] A protrusion 35 is formed on the gripping portion 31 that grips the heater 45. This makes it possible to prevent the insulating material 8 from entering the first space R1 when the insulating material 8 is foamed, and to prevent the front edge portion 5A from deforming and the insulating material 8 from entering the gap between the heater 45 and the front edge portion 5A.

[0033] If the heater 45 is displaced from the position held by the holding portion 31, a relatively large amount of energy is required to suppress condensation on the corner portion 50A, to suppress the adhesion of frost, or to melt the frost. Also, for example, if the heater 45 is attached by sticking it with tape, the position is likely to be displaced. The connecting member 9 according to this embodiment is positioned by the holding portion 31 on the outer side of the outer edge sealing member 50, particularly the corner portion 50A, of the storage facility 1, so that the heater 45 can heat the front edge portion 5A at an appropriate position, and the power consumption of the heater 45 can be reduced. In this manner, by gripping heater 45 with gripping portion 31, the position of heater 45 is fixed, the occurrence of condensation can be efficiently suppressed, and the power consumption of heater 45 can be reduced.

[0034] [1-3. Effects, etc.] As described above, the storage facility 1 in this embodiment has a door 4 (door body) that opens and closes the opening 2B of the storage facility main body 1 having a storage chamber 2A, the storage facility main body 2 is formed by sandwiching an insulating material 8 between an outer plate 5 and an inner plate 7, the outer plate 5 has a bent portion 5X that is bent at the position of the opening 2B and extends toward the back wall 135 of the storage chamber 2A, an end of the bent portion 5X and an end 7A of the inner plate 7 are connected by a connecting member 9, the end of the bent portion 5X has a fold-back body 5C that is bent at an acute angle toward the flat inner surface of the bent portion 5X, and the connecting member 9 has an engaging portion 29 with which the fold-back body 5C engages.

[0035] According to this, the engagement portion 29 of the connecting member 9 engages with the folded body 5C that is bent at an acute angle of the outer plate 5. This improves the connection between the connecting member 9 and the outer plate 5, or between the connecting member 9 and the inner plate 7. Furthermore, by improving the connection between the connecting member 9 and the outer plate 5, or between the connecting member 9 and the inner plate 7, deformation of the storage body 2 can be prevented, and the cooling effect can be improved. The back surface of the front edge portion 5A corresponds to an example of the "flat inner surface of the bent portion."

[0036] In addition, the connecting member 9 includes an outer member 21 facing the inner surface of the opening 2B, an inner member 25 on the inside of the storage body 2, and a column portion 23 connecting each of the members, and the folded portion 5X of the outer panel 5 extends between the outer member 21 and the inner member 25, and an engagement portion 29 with which the folded body 5C engages is formed on the inner surface of the inner member 25, and the engagement portion 29 may include an inclined guide portion 29A that guides the tip portion 5Ca of the folded body 5C, and a stopper portion 29B against which the tip portion 5Ca of the folded body 5C abuts.

[0037] According to this, the folded-back body 5C is guided by the inclined guide portion 29A and is caught by the stopper portion 29B. Therefore, the connection between the connecting member 9 and the outer plate 5, or between the connecting member 9 and the inner plate 7, can be improved.

[0038] Furthermore, the inner surface of the outer member 21 may be provided with a plurality of protrusions 39A, 39B that come into contact with the outer surface of the bent portion 5X of the outer plate 5.

[0039] According to this, the protrusions 39A and 39B guide the bent portion 5X to an appropriate position, thereby improving the connection between the connecting member 9 and the outer plate 5, or between the connecting member 9 and the inner plate 7.

[0040] The outer member 21 may be provided with a positioning protrusion 37 that positions the connecting member 9 by contacting the bent portion 5X of the outer plate 5 with the inner surface thereof.

[0041] According to this, the positioning projection 37 guides the bent portion 5X to an appropriate position, thereby improving the connection between the connecting member 9 and the outer plate 5, or between the connecting member 9 and the inner plate 7.

[0042] The connecting member 9 may have an inner surface abutment portion 35 that abuts the flat inner surface of the folded portion 5X, and a pressing portion 27 that abuts the inner surface of the inner plate 7, and the end portion 7A of the inner plate 7 may be clamped between the outer member 21 and the pressing portion 27.

[0043] According to this, the inner surface abutment portion 35 guides the bent portion 5X to an appropriate position, thereby improving the connection between the connecting member 9 and the outer plate 5, or between the connecting member 9 and the inner plate 7.

[0044] (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. In addition, it is also possible to combine the components described in the above-mentioned first embodiment to create a new embodiment. Therefore, other embodiments will be exemplified below.

[0045] In the first embodiment, the storage cabinet 1 having four doors 4 has been described as an example of a refrigerator. The doors 4 may be any doors that can open and close the storage cabinet main body 2. Therefore, the number of doors 4 is not limited to four. In the first embodiment, the gripping portion 31 is formed with a substantially semicircular recess on the inside, but the gripping portion 31 only needs to grip the heater 45 so as not to shift the position of the heater 45. Therefore, the gripping portion 31 is not limited to a substantially semicircular shape. For example, as shown in Fig. 6, the gripping portion 31 may be formed with a polygonal recess on the inside. Furthermore, a pair of claws 31C may be formed so as to be able to grip the outer periphery of the heater 45 when the heater 45 is gripped inside the gripping portion 31. This reduces the contact area between the gripping portion 31 and the heater 45, improving the efficiency of heat transfer from the heater 45 to the leading edge portion 5A of the outer plate 5 and reducing the power consumption of the heater 45. In the first embodiment, the heater 45 is described as an electric heater whose heat source is electricity. However, the present invention is not limited to this, and may be, for example, a pipe for passing airflow that utilizes exhaust heat from a machine room. In addition, in the first embodiment, the storage facility 1 is a commercial upright refrigerator, but the present invention is not limited to this and may be applied to refrigerators such as under-counter type commercial refrigerators and household refrigerators having multiple storage compartments formed by dividing them with partitions or the like.

[0046] 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, and the like can be made within the scope of the claims or their equivalents.
