[0007] <Embodiment> FIG. 1 is a perspective view of a refrigerator 100 according to the first embodiment. The refrigerator 100 (storage facility) is an appliance for storing food and the like at low temperatures, and in the example of FIG. 1, has a rectangular parallelepiped shape. The refrigerator 100 can be used alone, or a plurality of refrigerators 100 can be stacked vertically or lined up horizontally. As shown in FIG. 1, the refrigerator 100 includes a housing 1, a door 2, and a plurality of legs 3. Inside the housing 1, one or a plurality of storage compartments 4 (see FIG. 2) are provided. The storage compartment 4 may be a refrigeration compartment or a freezer compartment.

[0008] The housing 1 includes a resin inner box 11 (see FIG. 2) that forms the storage chamber 4 (see FIG. 2), and an outer plate 12 made of a steel plate (metal), as well as a heat-insulating box body 13 (heat insulating material: see FIG. 2) interposed between the inner box 11 and the outer plate 12. The housing 1 includes a removable top plate 14 as a thin resin plate provided on the upper surface. For example, when another refrigerator (not shown) is stacked above the refrigerator 100, the top plate 14 is removed. With the top plate 14 removed, the top plate 12a (see FIG. 8) is exposed. The top plate 14 may not be removable.

[0009] The door 2 is a door that closes the opening 11a (see FIG. 2) of the inner box 11. The door 2 is rotatable about the axis of a hinge 2b (see FIG. 3) and is opened and closed when putting in or taking out food or the like. A handle 2a for a user to hold is provided on the top surface or the like of the door 2. In the first embodiment, a case will be described in which a single-wing door 2 with the right end side as the pivot axis is used, but the door 2 may be a single-wing door with the left end side as the pivot axis or a double-wing door.

[0010] The legs 3 support the housing 1. In the example of FIG. 1, one leg 3 is provided on each of the left and right sides near the front end of the housing 1, which has a rectangular shape when viewed from below. These legs 3 are screwed into, for example, a female threaded portion (not shown) provided on a base member 90 (see FIG. 2), and adjust the height position of the housing 1 by the depth of the screwing (that is, function as an adjuster). The rear side of the housing 1 is supported by a protruding portion 90a (see FIG. 2) of the base member 90 (see FIG. 2). Note that a pair of left and right legs may also be provided on the rear side of the housing 1.

[0011] FIG. 2 is a vertical cross-sectional view of the refrigerator 100 taken along line II-II shown in FIG. The inner box 11 shown in Fig. 2 is a resin member that forms the storage chamber 4 together with the door 2, and is open at the front. As shown in Fig. 2, when the door 2 is closed, the opening 11a of the inner box 11 is blocked by the door 2. Furthermore, shelves 15 are provided in a predetermined manner on a plurality of shelf ribs 11b of the inner box 11. The insulating box body 13 is a box body for suppressing heat transfer between the inside and outside of the refrigerator 100, and is open at the front. The inner box 11 is fitted into the opening 13a of the insulating box body 13 (see Fig. 3).

[0012] The refrigerator 100 includes a compressor 31, a radiator 32 (see FIG. 4), a capillary tube (not shown), and a cooler 33. A refrigerant is circulated through the compressor 31, the radiator 32 (see FIG. 4), the capillary tube (not shown), and the cooler 33 in this order.

[0013] As shown in Fig. 2, a machine room 41 is provided at the bottom of the rear side (back side) of the refrigerator 100. The machine room 41 is a space in which a compressor 31 and a radiator 32 (see Fig. 4) are installed. The cooler 33 shown in Fig. 2 is a heat exchanger in which heat exchange takes place between a refrigerant flowing through its heat transfer tube and the air in the storage chamber 4. The air cooled by the cooler 33 is returned to the storage chamber 4, thereby cooling food and the like in the storage chamber 4.

[0014] A dew tray 34 is provided below the cooler 33 and on the inside of the inner box 11. The dew tray 34 receives condensation water that drips from the cooler 33. A drain pipe 35 is connected to the dew tray 34. The drain pipe 35 is a pipe that guides the condensation water in the dew tray 34 to an evaporation tray 36 (see FIG. 4) in the machine room 41.

[0015] FIG. 3 is an exploded perspective view of the refrigerator 100. As shown in FIG. 3, the refrigerator 100 includes an inner box 11, a door 2, a heat-insulating box body 13, a frame 20, an outer plate 12, and a double-sided tape 51. As described above, the inner box 11 is a resin member that forms the storage chamber 4 (see FIG. 2). The material of the inner box 11 is, for example, polystyrene, but is not limited thereto. The thickness of the inner box 11 may be, for example, within a range of 1 mm or more and 5 mm or less. In addition, the thickness of the inner box 11 is preferably 3 mm or more. By making the thickness of the inner box 11 thicker in this way, deformation of the inner box 11 when a predetermined force is applied can be suppressed.

[0016] 3, the inner box 11 includes a main body 11c that is open at the front side, and a flange 11d that protrudes outward from the edge of the opening 11a of the main body 11c. The main body 11c and the flange 11d are integrally formed.

[0017] As described above, the insulating box 13 is a box for suppressing heat transfer between the inside and outside of the refrigerator 100. The insulating box 13 may be configured by assembling a plurality of insulating material blocks, or may be integrally formed in a box shape with an opening at the front side. The inner wall surface of the insulating box 13 has a shape corresponding to the outer wall surface of the inner box 11.

[0018] The heat-insulating box 13 (heat-insulating material) is made of a molded heat-insulating material (such as polystyrene foam) or a vacuum heat-insulating material, and is already molded. By using a heat-insulating material that has already been molded in this way, for example, a process of injecting liquid urethane foam into the gap between the inner box 11 (see FIG. 2) and the outer plate 12 (see FIG. 2) is not required during manufacturing. Therefore, in addition to a mold used for injecting the urethane foam, it is not necessary to prepare equipment that applies pressure from inside and outside the refrigerator to push back the foaming pressure, and the manufacturing cost and equipment cost of the refrigerator 100 can be significantly reduced. In addition, the molded heat-insulating material and the vacuum heat-insulating material have the advantage that they are easier to disassemble and reuse when disposed of than urethane foam.

[0019] The frame 20 is a metal member for increasing the rigidity against the self-weight and external forces of the door 2, etc. The frame 20 includes an upper end connecting member 21 (plate portion), a front vertical support member 22, and a lower end connecting member 23, as well as an upper end support member 24, a rear vertical support member 25, a lower end support member 26 (see also FIG. 4), and a bottom plate 27.

[0020] 3, the upper end connecting member 21, a pair of front vertical support members 22, and the lower end connecting member 23 are connected in a rectangular frame shape and are arranged near the opening 11a of the inner box 11. The upper end supporting member 24 and the rear vertical support member 25 are connected in an upside down L shape and are arranged outside the heat-insulating box 13. Note that in practice, each member of the frame 20 (such as the upper end connecting member 21 and the vertical support members 22) is installed one by one in the heat-insulating box 13 with the inner box 11 fitted in, and is connected to other members during the installation process.

[0021] The bottom plate 27 is a metal plate that separates the machine room 41 (see FIG. 2) from the rest, and has a crank shape in side view. The outer plate 12 includes a top plate 12a (see FIG. 8 as well), a left side plate 12b, a right side plate 12c, and a rear plate 12d. The top plate 12a is a plate that is exposed on the upper surface of the housing 1 (see FIG. 1) when the top plate 14 (see FIG. 8 as well) is removed, and has a rectangular shape in plan view. The top plate 12a may be made of metal or resin.

[0022] The left side plate 12b is a rectangular steel plate forming the left side surface of the housing 1 (see FIG. 1). The right side plate 12c is a rectangular steel plate forming the right side surface of the housing 1 (see FIG. 1). The rear plate 12d is a rectangular steel plate forming the rear surface of the housing 1 (see FIG. 1). When assembling the refrigerator 100, the frame 20 is disposed on the outside of the insulating box body 13, and further, the outer plate 12 is disposed on the outside of the frame 20. The double-sided tape 51 shown in FIG. 3 is a tape for fixing the upper end side connecting member 21 to the flange 11d of the inner box 11. The double-sided tape 51 will be described in detail later.

[0023] FIG. 4 is a perspective view including the frame 20 and the base member 90 of the refrigerator (also see FIG. 3 as appropriate). The upper end connection member 21 (plate portion) shown in Fig. 4 is a metal member provided near the ridge between the top surface and the front surface of the housing 1 (see Fig. 1) and extends in the left-right direction. Both ends of the upper end connection member 21 are fixed to the front ends of the pair of vertical support members 22 by screws or the like.

[0024] The pair of front vertical support members 22 and the pair of rear vertical support members 25 are metal members provided near the ridges between adjacent side surfaces of the housing 1 (see FIG. 1) and extend in the vertical direction. The vicinity of the upper end of the front vertical support member 22 is fixed (connected) to the end of the upper end connection member 21 (plate portion) with a screw or the like, and is also fixed to the vicinity of the front end of the upper end support member 24 with a screw or the like. The vicinity of the upper end of the rear vertical support member 25 is fixed to the vicinity of the rear end of the upper end support member 24 with a screw or the like.

[0025] The pair of upper end support members 24 are metal members provided near the ridge between the upper surface and the side surface of the housing 1 (see FIG. 1) and extend in the front-rear direction. The lower end connection member 23 is a metal member provided near the ridge between the lower surface and the front surface of the housing 1 (see FIG. 1) and extends in the left-right direction. Both ends of the lower end connection member 23 are connected to the vicinity of the front end of the lower end support member 26. The pair of lower end support members 26 are metal members provided near the ridge between the lower surface and the side surface of the housing 1 and extend in the front-rear direction.

[0026] In this manner, frame 20 of refrigerator 100 is disposed so as to correspond to the ridge lines of rectangular parallelepiped housing 1 (see FIG. 1). As a result, even when a plurality of refrigerators 100 are stacked vertically, for example, a load acting from above can be firmly supported by frame 20. In particular, four metal vertical support members 22, 25 have a fairly high rigidity against a load from above, and are therefore suitable for stacking a plurality of refrigerators 100.

[0027] The bottom plate 27 shown in FIG. 4 is a metal plate that separates the machine room 41 (see FIG. 2) from the rest and also supports the load from above, and has a crank shape when viewed from the side. Base member 90 is a metal plate forming the lower surface of refrigerator 100 (storage compartment: see FIG. 1), and is installed below bottom plate 27. In the example of FIG. 4, air inlet 37 and air outlet 38 are provided side by side on the front wall of base member 90. Behind air inlet 37, radiator 32 and compressor 31 are arranged in that order. Behind air outlet 38, evaporator tray 36 is provided. In addition, a fan (not shown) that pressurizes and blows air in machine room 41 (see FIG. 2) is installed on base member 90.

[0028] The air flowing in through the intake port 37 passes through the radiator 32, passes above the evaporator dish 36, and is then blown out through the outlet port 38. Although the radiator 32 is shown in a simplified form in Fig. 4, the radiator 32 has a configuration in which a heat transfer tube 32a penetrates a number of fins (not shown). The arrangement of the intake port 37 and the outlet port 38 shown in Fig. 4 is one example, and is not limited thereto.

[0029] As shown in Fig. 4, the pair of legs 3 on the left and right sides at the front of the refrigerator 100 (see Fig. 1) not only supports the housing 1 (see Fig. 1) as described above, but also function as adjusters for adjusting the height. Each of these legs 3 has a screw portion (not shown) that is attached to the base member 90. The height position of the housing 1 is adjusted by the depth to which the screw portion (not shown) is screwed into the base member 90.

[0030] In such a configuration, the vertical support members 22 may not be screwed to the base member 90, or the vertical support members 22 may be screwed to the base member 90.

[0031] For example, the lower end of the vertical support member 22 is bent in a predetermined manner to provide a horizontal portion (not shown), which is in contact with the base member 90. As a result, when an external force is generated that compresses the housing 1 in the vertical direction, the load acts on the upper and lower ends of the vertical support member 22. The vertical support member 22 can withstand this load within the range of its own buckling strength, so deformation of the housing 1 can be prevented.

[0032] It is preferable that both the vertical support member 22 and the leg 3 are provided at the corners of the housing 1. In order to prevent interference between a horizontal portion (not shown) at the lower end of the vertical support member 22 and a threaded portion (not shown) of the leg 3, the horizontal portion may be provided with an insertion portion for the threaded portion. Also, the vertical support member 22 may have a configuration in which the vicinity of its lower end is not bent.

[0033] In the example of Fig. 4, since the rear side of the housing 1 is supported by the convex portion 90a (see Fig. 2) on the underside of the base member 90, there is no risk of the rear vertical support member 25 interfering with the threaded portion (not shown) of the leg 3. Therefore, the rear vertical support member 25 may be screwed to the base member 90. Note that if a leg (not shown) is provided on the rear side of the housing 1, the rear vertical support member 25 may not be screwed to the base member 90.

[0034] FIG. 5 is a perspective view of the vicinity of hinge 2b of door 2 in refrigerator 100. As shown in FIG. 5 shows a state in which the top plate 14 (see FIG. 8) and the top plate 12a (see FIG. 8) are removed from the refrigerator 100. The hinges 2b shown in FIG. 5 are used for opening and closing the door 2, and are installed on the upper and lower sides of the rotation shaft of the door 2 (near the right end of the door 2 in FIG. 5).

[0035] The upper hinge 2b is fixed to the upper surface of the upper end connecting member 21 with a screw 61. To explain in more detail, the upper end connecting member 21 is sandwiched between the hinge 2b and a hinge fixing plate (not shown) from above and below, and the hinge 2b is fixed by fastening the screw 61 to the hinge fixing plate (not shown). The weight of the door 2 and the like act on the upper end connecting member 21 via the hinge 2b.

[0036] FIG. 6 is an explanatory diagram showing the influence of the weight of the door 2 in the refrigerator 100. The dashed line drawn on the housing 1 in Fig. 6 indicates the ridgeline of the housing 1 deformed by the load applied via the hinge 2b (load source: see Fig. 5) of the door 2. For ease of understanding, the degree of deformation of the housing 1 is exaggerated in Fig. 6 compared to the actual degree. The door 2 shown in FIG. 6 is supported by an upper hinge 2b (see FIG. 5) and a lower hinge (not shown). A force F1 due to the weight of the door 2 acts on the center of gravity G1 of the door 2. Here, the center of gravity G1 of the door 2 is located at a position shifted to the left in the horizontal direction from a vertical line (a line connecting a point of application P1 and a fulcrum P2) connecting the upper hinge 2b (see FIG. 5) and the lower hinge (not shown). Due to this relationship, a predetermined rotational force M1 (moment of force) is generated in the housing 1 between the center of gravity G1 of the door 2 and the lower hinge (not shown).

[0037] That is, a rotational force M1 is generated with the center of gravity G1 of the door 2 as the force point, the lower hinge (not shown) as the fulcrum P2 (center of rotation), and the upper hinge 2b (see FIG. 5) as the action point P1. This rotational force M1 is transmitted to the housing 1 via the upper hinge 2b (see FIG. 5). As a result, a predetermined twist is qualitatively generated in the housing 1. In reality, the resultant force of various forces, such as the weight of the door 2 itself, the load of food or the like in the door pocket (not shown), and the magnetic force attracting the door 2, acts on the door 2, but there is no particular difference in that the twist is generated in the housing 1.

[0038] The smaller the torsional rigidity of the housing 1 against such a rotational force M1, the larger the torsion of the housing 1. Furthermore, since a molded insulating material or a vacuum insulating material is used as the insulating box body 13 (see FIG. 3), the inner box 11 (see FIG. 3), the insulating box body 13 (see FIG. 3), and the outer plate 12 (see FIG. 3) are less likely to be mechanically integrated than when liquid urethane foam is injected. Therefore, the interface between adjacent members in the thickness direction (for example, the inner box 11 and the insulating box body 13) is more likely to shift in the in-plane direction. Therefore, in the first embodiment, the rotational force M1 acting on the housing 1 is also distributed to the inner box 11, thereby increasing the torsional rigidity of the housing 1.

[0039] FIG. 7 is a perspective view including the inner box 11, the frame 20, and the double-sided tape 51 of the refrigerator. 7, as described above, the flange 11d protrudes outward from the edge of the opening 11a of the main body 11c and has a rectangular frame shape when viewed from the front. The flange 11d has a function of receiving a force (load) acting from the hinge 2b (see FIG. 5) via the upper end side connecting member 21 in addition to positioning the heat-insulating box 13 (see FIG. 8).

[0040] The upper end connecting member 21 shown in Fig. 7 is made of a thin metal plate that has been subjected to a predetermined bending process, and is installed on the upper edge of the flange 11d. The pair of front vertical support members 22 are installed on the left and right edges of the flange 11d, respectively. The lower end connecting member 23 is installed on the lower edge of the flange 11d.

[0041] The double-sided tape 51 is a tape for fixing the upper end side connection member 21 to the flange 11d. For example, by using a heat insulating tape as the double-sided tape 51, heat transfer between the inside and outside of the refrigerator 100 can be suppressed. There is no particular problem even if the double-sided tape 51 is not heat insulating. In the example of FIG. 7, the double-sided tape 51 is attached to the front surface of the upper edge part of the flange 11d over substantially the entire area in the lateral direction. By fixing the upper end side connection member 21 and the flange 11d with the double-sided tape 51 (i.e., by fixing the "plate part" to the flange 11d), the overall torsional rigidity of the refrigerator 100 is increased. That is, even if a rotational force M1 (see FIG. 6) acts on the housing 1, a part of the force is transmitted to the inner box 11 via the upper end side connection member 21 and the flange 11d, so that the overall torsion of the refrigerator 100 is reduced. The first surface portion 21a and the second surface portion 21b of the upper end side connecting member 21 shown in FIG. 7 will be described with reference to the next FIG.

[0042] FIG. 8 is a vertical cross-sectional view of the vicinity of flange 11d of inner box 11 in refrigerator 100. As shown in FIG. As described above, the flange 11d of the inner box 11 shown in Fig. 8 protrudes outward (upward in Fig. 8) from the edge of the main body 11c whose front side is open. The front edge of the heat-insulating box 13 is abutted against the flange 11d to be positioned. A sealant (not shown) may be provided so as to be sandwiched between the flange 11d of the inner box 11 and the front edge of the heat-insulating box 13. This makes it possible to prevent moisture and the like from entering through a minute gap between the inner box 11 and the heat-insulating box 13.

[0043] As shown in Fig. 8, the upper end connection member 21, which is one of the frames 20 (see Fig. 3), is provided on the outside (upper side in Fig. 8) of the insulating box body 13. As described above, the hinge 2b is fixed to the upper surface of the upper end connection member 21 with the screw 61 (see also Fig. 5). The part of the hinge 2b that overlaps with the upper end connection member 21 in a plan view is covered with the top plate 12a. As a result, the fixed part of the hinge 2b is hidden by the top plate 12a, improving the design of the refrigerator 100.

[0044] As shown in Fig. 8, the flange 11d includes an outer edge portion 11f, a pipe groove 11m, a recessed portion 11g, a rib 11h, a jaw portion 11k, and a locking groove 11p (groove). The outer edge portion 11f (see also Fig. 9) is a portion including the outer edge of the flange 11d. More specifically, the portion that is outer than the recessed portion 11g (described below, upper side in Fig. 8) is the outer edge portion 11f.

[0045] The pipe groove 11m (see also FIG. 9) is a groove in which a heat transfer tube 39 (hot gas pipe) is provided, and is recessed from the front surface of the outer edge portion 11f to the rear side. In the example of FIG. 8, the pipe groove 11m is provided over substantially the entire circumference of the flange 11d, which has a rectangular frame shape when viewed from the front. Then, a medium-temperature, high-pressure refrigerant (hot gas) compressed by the compressor 31 (see FIG. 4) and condensed by the radiator 32 (see FIG. 4) flows through the heat transfer tube 39 provided in the pipe groove 11m.

[0046] This makes it possible to suppress condensation near the opening 11a of the inner box 11. In addition, since the heat of the heat transfer tube 39 is also transferred to the upper end side connecting member 21, even if air containing moisture enters the gap between the top plate 12a and the heat-insulating box body 13, the occurrence of condensation can be suppressed.

[0047] The recess 11g (see also FIG. 9) is a portion recessed toward the rear on the inside (lower side in FIG. 8) of the outer edge portion 11f. The recess 11g may be provided over substantially the entire circumference of the rectangular frame-shaped flange 11d in front view, or may be provided only on the upper edge portion of the rectangular frame-shaped flange 11d. A locking recess 111g is provided near the lower end of the recess 11g, which is recessed particularly deeply so that the tip of the vertical regulating portion 21c described below can be inserted deeply in the front-rear direction. The vertical groove width of the locking recess 111g is slightly longer than the thickness of the vertical regulating portion 21c.

[0048] The rib 11h (see also FIG. 9) prevents the upper end connecting member 21 from being misaligned in the up-down direction, and protrudes forward from the bottom surface of the recess 11g. In the lateral direction, a plurality of ribs 11h (see also FIG. 9) are provided at predetermined intervals. In the up-down direction, the rib 11h is provided below the outer edge portion 11f and above the jaw portion 11k.

[0049] The upper part of the curved edge of the rib 11h in side view is substantially flush with the front surface of the outer edge portion 11f, and the lower part of the curved edge is substantially flush with the wall surface of the locking recess 111g. The edge of the rib 11h in side view is curved so as to go in toward the rear side (deep side) as its height position becomes lower.

[0050] As described above, the edge of the rib 11h is substantially flush with the front surface of the outer edge portion 11f, so that the double-sided tape 51 is also affixed to the front surface of the rib 11h. This ensures a sufficient adhesion area between the flange 11d including the rib 11h and the double-sided tape 51. In addition, the provision of the rib 11h increases the rigidity of the inner box 11, thereby making it possible to suppress deformation of the inner box 11.

[0051] The jaw portion 11k (see also FIG. 9) is a portion that protrudes forward from the bottom surface of the recess 11g on the inside of the recess 11g (lower side in FIG. 8) and extends laterally. As shown in FIG. 8, the jaw portion 11k is flush with the inner wall surface of the main body portion 11c of the inner box 11.

[0052] The locking groove 11p (groove) is a groove into which the vertical regulating portion 21c of the upper end side connecting member 21 is fitted, and is provided as a gap between the rib 11h and the jaw portion 11k. The bottom surface of the locking recess 111g forms the bottom surface of the locking groove 11p. As shown in FIG. 8, the vertical distance between the rib 11h and the jaw portion 11k becomes shorter toward the rear side. In other words, the locking groove 11p formed by the curved edge of the rib 11h and the upper surface of the jaw portion 11k has a tapered shape in a vertical cross section. As a result, when the upper end side connecting member 21 is installed, the tip of the vertical regulating portion 21c is guided to face the locking recess 111g, making it easier to install the upper end side connecting member 21.

[0053] As described above, the upper end connection member 21 (plate portion: see also FIG. 7) is a metal member on which the hinge 2b of the door 2 (see FIG. 5) is installed, and extends in the left-right direction. As shown in FIG. 8, the upper end connection member 21 includes a first surface portion 21a having a horizontal surface direction, a second surface portion 21b extending downward from the front end of the first surface portion 21a, and a vertical regulating portion 21c extending rearward from the lower end of the second surface portion 21b. That is, the upper end connection member 21 is formed in a hook shape (J-shape) near its front end in a vertical cross section. The vertical regulating portion 21c is fitted into the locking groove 11p of the flange 11d, so that the upper end connection member 21 is locked. Note that the surface direction of the first surface portion 21a being "horizontal" is not limited to being strictly horizontal, but also includes a case in which there is a predetermined error (deviation from the horizontal direction).

[0054] 8, the lower surface of the first surface portion 21a is in contact with (or close to) the upper surface of the heat-insulating box 13. The upper end connecting member 21 is positioned by the flange 11d of the inner box 11 and the heat-insulating box 13. The second surface portion 21b is fixed to the flange 11d by double-sided tape 51 (i.e., the second surface portion 21b is fixed to the flange 11d). As described above, the vertical regulation portion 21c is fitted into the locking groove 11p of the flange 11d.

[0055] In a state where the vertical regulating portion 21c is fitted into the locking groove 11p (groove), the rib 11h is located on the rear side of the second surface portion 21b, and the jaw portion 11k is located on the lower side of the vertical regulating portion 21c. The procedure for installing each member will be described below. After the heat transfer tube 39 is installed in the pipe groove 11m, one side of the double-sided tape 51 is attached to the front surface of the flange 11d, and the other side of the double-sided tape 51 is attached to the rear surface (rear surface) of the second surface portion 21b. In this state, the front surface of the jaw portion 11k and the second surface portion 21b are substantially flush with each other, and the heat transfer tube 39, the rib 11h, and the like are hidden by the upper end side connecting member 21, thereby improving the design of the refrigerator 100.

[0056] As described above, the double-sided tape 51 is used to fix the upper end connection member 21 and the flange 11d. If the upper end connection member 21 and the flange 11d are fixed with a screw (not shown), the head of the screw (not shown) protrudes from the front surface of the second surface portion 21b, which makes it easy for a gap to occur between the door 2 in the closed state (see FIG. 5) and the second surface portion 21b. In contrast, in the first embodiment, the double-sided tape 51 is used, which makes it easy for the door 2 in the closed state (see FIG. 5) and the second surface portion 21b to adhere closely to each other, thereby ensuring the thermal insulation of the refrigerator 100. In addition, the second surface portion 21b, which is easily visible to the user when the door 2 is opened, is flat, which improves the design of the refrigerator 100.

[0057] Furthermore, since the upper end connecting member 21 is fixed to the flange 11d with the double-sided tape 51, a rotational force M1 (see FIG. 6) caused by the weight of the door 2 (see FIG. 5) or the like acts on the inner box 11 via the hinge 2b (see FIG. 5), the upper end connecting member 21, the double-sided tape 51, and the flange 11d in this order. Therefore, the rotational force caused by the weight of the door 2 (see FIG. 5) or the like can be distributed to the inner box 11 as well, so that the overall twisting of the refrigerator 100 is reduced.

[0058] If the double-sided tape 51 were not provided, the rotational force due to the weight of the door 2 (see FIG. 5) would act particularly strongly on the upper end connecting member 21, and the flange 11d and the upper end connecting member 21 would be likely to shift in the shear direction or separate in the front-rear direction. In other words, if the double-sided tape 51 were not provided, the rotational force would be difficult to disperse to the inner box 11, and the housing 1 (see FIG. 6) would be prone to twisting. In contrast, in the first embodiment, as described above, the inner box 11 and the upper end connecting member 21 are fixed with the double-sided tape 51, so that the rotational force due to the weight of the door 2 is reliably distributed to the inner box 11 as well. Therefore, the torsional rigidity of the housing 1 (see FIG. 6) is increased, and deformation of the housing 1 can be suppressed.

[0059] FIG. 9 is a partial enlarged view of region K1 in FIG. As described above, the upper edge of the flange 11d shown in Fig. 9 is provided with the pipe groove 11m recessed from the front surface of the outer edge portion 11f to the rear side, the recess 11g provided inside (below) the pipe groove 11m, and a plurality of ribs 11h, as well as the jaw portion 11k connected to the inner wall surface of the opening 11a. The right edge of the flange 11d is also provided with the pipe groove 11m, the recess 11g, the rib 11h, etc. In addition, although not shown in Fig. 9, the left edge and the lower edge of the flange 11d are also provided with the pipe groove 11m, the recess 11g, the rib 11h, etc. (that is, approximately around the entire circumference of the flange 11d).

[0060] The inner box 11 is formed, for example, by injection molding using a predetermined resin. By performing injection molding in this way, the inner box 11 having a complex shape can be formed with high precision. In injection molding, it is recommended to reduce the difference in thickness of each part of the molded product (i.e., the inner box 11) in order to suppress molding defects. In the first embodiment, a recess 11g (see also FIG. 8) is provided in the flange 11d to make the thickness of the inner box 11 uniform. By providing a rib 11h in such a recess 11g, the groove width of the locking groove 11p (see FIG. 8) between the rib 11h and the jaw portion 11k becomes narrow. By fitting the vertical regulating portion 21c (see FIG. 8) into such a locking groove 11p, it is possible to suppress the vertical positional deviation of the upper end side connecting member 21 (see FIG. 8). As a result, it is possible to suppress the transmission loss of force from the upper end side connecting member 21 to the inner box 11.

[0061] According to the first embodiment, since the inner box 11 is fixed to the upper end side connecting member 21 with the double-sided tape 51 (see FIG. 7), the rotational force caused by the weight of the door 2 or the like can be dispersed to the inner box 11 as well. Therefore, the torsional rigidity of the housing 1 (see FIG. 6) can be increased, and deformation of the housing 1 can be suppressed. In addition, when the door 2 is opened, tilting of the refrigerator 100 due to the weight of the door 2 or the like can be prevented.

[0062] Furthermore, according to the first embodiment, since a molded insulating material or a vacuum insulating material is used as the insulating box 13 (insulating material), the manufacturing cost of the refrigerator 100 can be reduced, and the refrigerator 100 can be easily disassembled and reused when disposed of.

[0063] In addition, since the upper end connecting member 21 is used as a member to be locked in the locking groove 11p (see FIG. 8), it is not necessary to lock the top plate 12a (see FIG. 8) in the locking groove 11p. This makes it possible to hide the fixing portion of the hinge 2b (see FIG. 5) of the door 2 with the top plate 12a (see FIG. 8), thereby improving the design of the refrigerator 100.

[0064] Second Embodiment The second embodiment differs from the first embodiment in that a double-sided tape 50 (see FIG. 12) is provided over substantially the entire periphery of the flange 11d (see FIG. 12) that has a rectangular frame shape when viewed from the front. The second embodiment also differs from the first embodiment in that the vicinity of the tip of the horizontal plate 12b (see FIG. 11) is fitted into the locking groove 11r (see FIG. 11) of the flange 11d. Note that the other points (such as the configuration of the upper edge of the flange 11d: see FIG. 8) are the same as those of the first embodiment. Therefore, only the parts that differ from the first embodiment will be described, and a description of the overlapping parts will be omitted.

[0065] FIG. 10 is a cross-sectional view showing a cross section of the refrigerator 100A when the upper part is cut away. In FIG. 10, the door 2 (see FIG. 1) of the refrigerator 100A is omitted. The refrigerator 100A includes a left side panel 12b, a right side panel 12c, and a rear panel 12d in addition to the above-mentioned top panel 12a (see FIG. 8) as the outer panels 12. Note that the side panels 12b and 12c and the rear panel 12d are thin, and therefore are illustrated as lines in FIG.

[0066] As shown in Fig. 10, vertical support members 22, 25 (see also Fig. 4) are provided at each of the four corners when the insulating box 13 with the inner box 11 fitted therein is viewed in cross section. To explain in more detail, a vertical support member 22 (see also Fig. 4) is provided at each of the left and right corners on the front side of the insulating box 13. Similarly, another vertical support member 25 (see also Fig. 4) is provided at each of the left and right corners on the rear side of the insulating box 13. In Fig. 10, the hinge 2c provided at the right front part of the refrigerator 100A is the lower hinge of the door 2 (see Fig. 2).

[0067] FIG. 11 is a partial enlarged view of region K2 in FIG. The front vertical support member 22 shown in Fig. 11 is L-shaped in cross section and is elongated in the up-down direction (see also Fig. 4). The left edge of the flange 11d abuts against the corner of the L-shaped cross section of the vertical support member 22. The part of the vertical support member 22 that is parallel to the left-right direction is disposed in front of the flange 11d of the inner box 11. The part of the vertical support member 22 that is parallel to the front-rear direction (the inner surface of the rear part) is in contact with the side of the insulating box 13.

[0068] 11, a sealant 71 may be provided between the flange 11d of the inner box 11 and the heat-insulating box body 13. This makes it possible to prevent moisture and the like from entering through a minute gap between the inner box 11 and the heat-insulating box body 13.

[0069] The flange 11d has a left edge portion including an outer edge portion 11f, a pipe groove 11m, a rib 11h, a jaw portion 11k, and a locking groove 11r. The left edge portion of the flange 11d shown in Fig. 11 is similar to the upper edge portion of the flange 11d (see Fig. 8) described in the first embodiment, and therefore a detailed description will be omitted. Note that, just as the upper edge portion of the flange 11d has a recess 11g (see Fig. 8), the left edge portion of the flange 11d also has a recess, but since Fig. 11 is a cross section including the rib 11h, the recess is not visible.

[0070] As shown in Fig. 11, a pipe groove 11m is provided in the flange 11d of the inner box 11, and a locking groove 11r is provided inside the pipe groove 11m (on the right side in Fig. 11). The locking groove 11r is a groove into which the left-right regulating portion 123b of the horizontal plate 12b is fitted, and is provided in the up-down direction at the left edge of the flange 11d. The upper end of the locking groove 11r shown in Fig. 11 may be connected to the locking groove 11p (see Fig. 8) at the upper edge of the flange 11d, or may not be connected.

[0071] 11, the vertical support member 22 is fixed to the flange 11d with double-sided tape 52. Specifically, after the heat transfer tube 39 is installed in the pipe groove 11m, one side of the double-sided tape 51 is attached to the flange 11d, and further, the other side of the double-sided tape 51 is attached to the rear surface (back surface) of the vertical support member 22.

[0072] The left horizontal plate 12b is installed on the outer side of the vertical support member 22. The horizontal plate 12b includes a flat portion 121b (third surface portion), a locking portion 122b (fourth surface portion), and a left-right restricting portion 123b. The flat portion 121b is a flat portion forming the left side surface of the refrigerator 100A (storage compartment). The locking portion 122b extends from the front end of the flat portion 121b toward the inside in the horizontal direction (to the right in FIG. 11). The left-right restricting portion 123b extends from the end of the locking portion 122b on the inside in the horizontal direction toward the rear side. That is, the front end of the horizontal plate 12b is formed in a hook shape (J-shape) in cross section. The left-right restricting portion 123b is fitted into the locking groove 11r of the flange 11d. The configuration of the right front portion of the refrigerator 100A is substantially symmetrical to the left front portion shown in FIG.

[0073] As shown in FIG. 11, the vertical support member 22, which is L-shaped in cross section, is sandwiched between the flat surface portion 121b of the horizontal plate 12b and the heat-insulating box body 13 in the horizontal direction. The vertical support member 22 is sandwiched between the locking portion 122b of the horizontal plate 12b and the flange 11d via the double-sided tape 52 in the front-rear direction. In this way, the vertical support member 22 is positioned by the horizontal plate 12b, the heat-insulating box body 13, and the flange 11d, and is fixed to the flange 11d with the double-sided tape 52. The left-right restricting portion 123b of the horizontal plate 12b is fitted into the locking groove 11r so as to cover the vertical support member 22 from the outside. In this way, the horizontal plate 12b is appropriately positioned, and the vertical support member 22 and the heat transfer tube 39 are hidden by the outer plate 12, thereby improving the design of the refrigerator 100.

[0074] Furthermore, when a predetermined rotational force acts so as to twist horizontal plate 12b, this rotational force acts on inner box 11 through vertical support member 22, double-sided tape 52, and flange 11d in this order. Therefore, rotational force M1 (see FIG. 6) caused by the weight of door 2 (see FIG. 5) or the like is also distributed to inner box 11, thereby increasing the overall torsional rigidity of refrigerator 100A. Horizontal plate 12b and vertical support member 22 may be mechanically integrated with each other by screwing or the like.

[0075] FIG. 12 is a perspective view including the inner box 11, the frame 20, and the double-sided tape 50 of the refrigerator 100A. 12, double-sided tape 50 is attached to substantially the entire area of ​​flange 11d, which is shaped like a rectangular frame when viewed from the front. Specifically, the upper-end connecting member 21 and the upper edge of flange 11d are fixed with double-sided tape 51. Furthermore, the left-side vertical support member 22 and the left edge of flange 11d are fixed with double-sided tape 52 (similar to the right side). Furthermore, the lower-end connecting member 23 and the lower edge of flange 11d are fixed with double-sided tape 53.

[0076] A locking groove (not shown) may also be provided on the front side of the lower edge of the flange 11d. Then, with the lower-end connecting member 23 locked in the locking groove, the flange 11d and the lower-end connecting member 23 may be fixed together with double-sided tape 53.

[0077] According to the second embodiment, substantially the entire periphery of the flange 11d, which is a square frame when viewed from the front, is fixed with double-sided tape 50. Therefore, the force acting on the housing 1 (see FIG. 6) is appropriately distributed to the inner box 11 via the frame 20. Furthermore, when a rotational force that twists the housing 1 is applied, the side surfaces of the housing 1 are likely to deform, but because the left and right edges of the flange 11d are fixed to the frame 20 with double-sided tape 52, respectively, deformation of the housing 1 can be appropriately suppressed.

[0078] Third Embodiment The third embodiment differs from the first embodiment in that the flange 11Bd (see FIG. 13) of the inner box 11B (see FIG. 13) has an extension 11t (see FIG. 13). The rest of the third embodiment is similar to the first embodiment. Therefore, only the parts that differ from the first embodiment will be described, and a description of the overlapping parts will be omitted.

[0079] FIG. 13 is a vertical cross-sectional view of the upper front part of a refrigerator 100B according to the third embodiment. As shown in Fig. 13, the inner box 11B of the refrigerator 100B has a flange 11Bd. The flange 11Bd has a flange main body 11s that protrudes outward from the edge of the opening 11a of the inner box 11B, and an extension portion 11t that extends rearward from the upper end of the flange main body 11s. The extension portion 11t transmits force from the upper end side connecting member 21 to the flange 11Bd, and also has a function of increasing the torsional rigidity of the inner box 11B itself. The extension portions 11t are provided on the upper edge portion of the flange 11Bd, as well as on the left edge portion, right edge portion, lower edge portion and four corner portions of the flange 11Bd (that is, around the entire circumference of the opening edge portion of the flange 11Bd), although not shown.

[0080] In the example of FIG. 13, the heat insulating box 13 is fitted up to the vicinity of the rear surface (back surface) of the flange main body 11s. The heat insulating box 13 is sandwiched between the main body 11c and the extension 11t of the inner box 11B. The upper end side connecting member 21 is in contact with (or in close proximity to) the extension 11t. To explain in more detail, the upper surface of the extension 11t is in contact with (or in close proximity to) the first surface 21a of the upper end side connecting member 21. The back surface of the first surface 21a of the upper end side connecting member 21 and the extension 11t may be fixed with double-sided tape (not shown). This makes it easier for the rotational force acting on the upper end side connecting member 21 from the hinge 2b to be transmitted to the inner box 11B via the double-sided tape (not shown).

[0081] According to the third embodiment, since the flange 11Bd of the inner box 11B has the extension portion 11t, the torsional rigidity of the housing 1B is further increased compared to the first embodiment. Therefore, the torsion of the refrigerator 100 can be effectively reduced.

[0082] Fourth Embodiment The fourth embodiment differs from the first embodiment in that a cushioning material 81 (see FIG. 14) is provided between the heat transfer tube 39 and the flange 11d. The fourth embodiment also differs from the first embodiment in that no double-sided tape is provided on the front side of the heat transfer tube 39 (see FIG. 14). The rest of the fourth embodiment is similar to the first embodiment. Therefore, only the parts that differ from the first embodiment will be described, and a description of the overlapping parts will be omitted.

[0083] FIG. 14 is a vertical cross-sectional view of the upper front part of a refrigerator 100C according to the fourth embodiment. The refrigerator 100C shown in Fig. 14 includes a cushion material 81 in addition to the components described in the first embodiment. The cushion material 81 is a member for bringing the heat transfer tube 39 into contact with (or close to) the upper end connecting member 21. As shown in Fig. 14, the cushion material 81 is provided on the rear side of the heat transfer tube 39 in the pipe groove 11m of the flange 11d. For example, the heat transfer tube 39 may be brought into contact with the upper end connecting member 21 by an elastic force caused by compressive deformation of the cushion material 81.

[0084] The refrigerator 100C also includes a first double-sided tape 51a and a second double-sided tape 51b as double-sided tapes for fixing the flange 11d of the inner box 11 and the upper-end connecting member 21. The first double-sided tape 51a is attached to the upper side of the heat transfer tube 39 at the outer edge portion 11f of the flange 11d. The second double-sided tape 51b is attached to the lower side of the heat transfer tube 39 at the outer edge portion 11f of the flange 11d as well as to the front edge of the rib 11h. The upper-end connecting member 21 is installed so as to cover the heat transfer tube 39 from the outside.

[0085] A first double-sided tape 51a and a second double-sided tape 51b are attached to the rear surface (rear surface) of the upper end connection member 21. Note that no double-sided tape is provided between the second surface 21b of the upper end connection member 21 and the heat transfer tube 39 (hot gas pipe) in the front-rear direction. In this configuration, the elastic force of the cushion material 81 brings the heat transfer tube 39 and the upper end connection member 21 into contact (or close to each other). Therefore, according to the fourth embodiment, heat from the heat transfer tube 39 is easily transferred to the metallic upper end connection member 21, so that condensation near the opening 11a of the inner box 11 can be suppressed.

[0086] <<Variations>> Although the refrigerator 100 and the like according to the present disclosure have been described in the above embodiments, the present disclosure is not limited to these descriptions and may be modified in various ways. For example, in each embodiment, the flange 11d of the inner box 11 is fixed to the upper end connecting member 21 with double-sided tape 51 (see FIG. 7), but this is not limited to the above. That is, instead of using double-sided tape 51, the flange 11d and the upper end connecting member 21 may be fixed to each other with screws (not shown) or an adhesive.

[0087] In addition, in each embodiment, the case where the upper end connecting member 21 directly bears the load of the hinge 2b has been described, but this is not limited thereto. For example, a specific member (not shown) may be interposed between the upper end connecting member 21 and the hinge 2b, and the upper end connecting member 21 may indirectly bear the load of the hinge 2b. Such a configuration is also included in the matter of the upper end connecting member 21 bearing the load of the hinge 2b.

[0088] In the first embodiment (see FIG. 7), the double-sided tape 51 is attached over substantially the entire upper edge of the flange 11d, but the present invention is not limited to this. For example, the double-sided tape 51 may be provided in the vicinity of the fixing location (near the right end of the upper edge of the flange 11d) of the hinge 2b (see FIG. 5) in the upper end connecting member 21 (see FIG. 5). Alternatively, pieces of double-sided tape having a relatively short length may be attached in a discrete manner in the lateral direction. Even in this configuration, the force acting on the upper end connecting member 21 via the hinge 2b is appropriately distributed to the inner box 11.

[0089] In addition, in each embodiment, the case where the housing 1 (see FIG. 1) of the refrigerator 100 is a rectangular parallelepiped has been described, but the present invention is not limited to this. For example, each embodiment can be applied to a refrigerator having a housing (not shown) that is a polyhedron other than a rectangular parallelepiped, or a housing (not shown) that includes a curved surface.

[0090] Moreover, the respective embodiments can be combined as appropriate. For example, the second embodiment (see FIG. 11) and the third embodiment (see FIG. 13) can be combined. In the third embodiment (see FIG. 13), the extension 11t is provided around the entire periphery of the opening edge of the flange 11Bd, but the extension 11t may be provided on at least a part of the opening edge of the flange 11Bd. For example, the extension 11t may be provided only on the upper edge of the flange 11Bd. Also, the extension 11t may be provided on each of the upper, left and right edges of the flange 11Bd, while the extension 11t may not be provided on the four corners of the flange 11Bd. In addition, extensions (not shown) may be provided near the four corners of the flange 11d, which has a rectangular frame shape when viewed from the front. Even with this configuration, the force acting on the housing 1 can be appropriately distributed to the inner box 11.

[0091] In addition, in each embodiment, the refrigerator 100 having a single-door door 2 (see FIG. 1) has been described, but the embodiments can be applied to other types of refrigerators such as double-door refrigerators, portable refrigerators, and chest-type freezers. The embodiments can also be applied to various types of "storage units" other than refrigerators. For example, the embodiments can also be applied to a specific storage unit that is not particularly provided with a cooler.

[0092] In addition, each embodiment has been described in detail to clearly explain the present invention, and is not necessarily limited to having all of the configurations described. In addition, it is possible to add, delete, or replace part of the configuration of an embodiment with other configurations. Furthermore, the above-mentioned mechanisms and configurations are those considered necessary for the explanation, and do not necessarily show all mechanisms and configurations of the product.
