Mode for Carrying Out the Invention

[0008] (Knowledge etc. on which the present disclosure is based) When the inventors arrived at the idea of the present disclosure, there was a technology as in Patent Document 1 in which an electrical component is housed in an electrical equipment box body provided in the electrical equipment box and can be pulled out. However, in the conventional technology, the terminal block is not arranged in the pulling-out direction of the electrical equipment box body, and it is necessary to pull out to the portion on the side opposite to the pulling-out direction of the electrical equipment box body or take out the entire electrical equipment box body. The inventors discovered the problem that the shipping inspection and on-site construction connection work related to the electrical equipment box are not easy, and in order to solve that problem, they came to constitute the subject matter of the present disclosure. Therefore, the present disclosure provides a storage box that can facilitate the shipping inspection and on-site construction connection work related to the electrical equipment box.

[0009] (Embodiment 1) Hereinafter, embodiments will be described in detail with reference to the drawings. However, there may be cases where more detailed explanations than necessary are omitted. For example, there may be cases where the detailed explanation of already well-known matters or the duplicate explanation for substantially the same configuration is omitted. The attached 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] [1-1. Configuration] [1-1-1. Configuration of the showcase] The reference symbol FR shown appropriately in each figure indicates the front of the storage 1 and the electric cabinet 20 in the installed state, the reference symbol UP indicates the upper part of the storage 1 and the electric cabinet 20, and the reference symbol LH indicates the left side of the storage 1 and the electric cabinet 20. In the following description, each direction is the direction along these directions. Also, in the present embodiment, the front is an example of the direction in which the electric cabinet body 21 is pulled out, and the rear is an example of the direction in which the electric cabinet body 21 is stored.

[0011] FIG. 1 is a front view of the storage 1 according to Embodiment 1. The storage 1 of Embodiment 1 is an open showcase having a front opening installed in a store such as a convenience store or a supermarket. The main body 2 is composed of a main body 2 having an open front and covering the upper, rear, side, and lower surfaces, and a display chamber 3. The main body 2 is provided with a heat-insulating wall portion 4, and an inner panel 6 is provided inside the display chamber 3.

[0012] The display chamber 3 has an open front, and inside, a plurality of pairs of brackets detachably attached to columns provided on the front side of an inner panel 6 located on the rear side of the display chamber 3, and shelf boards 8 supported by these brackets are installed in multiple stages. And the goods are configured to be displayed on the upper surface of the shelf board 8. That is, the storage 1 can accommodate articles.

[0013] Inside the storage compartment 1, a compressor, a condenser, a fan, etc. that constitute a refrigeration cycle are arranged. Inside the cold air duct located on the rear side of the inner panel 6, an evaporator that constitutes a refrigeration system is arranged. By driving the compressor and the fan, the cold air that has exchanged heat with the evaporator rises inside the cold air duct and is discharged toward the front opening. Due to the cold air discharged from the front opening, an air curtain of cold air is formed at the front opening, and a part of this cold air air curtain is circulated inside the display compartment 3.

[0014] Note that the refrigeration cycle is not limited to the built-in type showcase. The storage compartment 1 may be a separate type showcase provided with an outdoor unit in which a compressor, a condenser, a fan, etc. that constitute a refrigeration cycle are provided separately from the main body 2 without arranging a compressor, a condenser, a fan, etc. that constitute a refrigeration cycle inside the main body 2.

[0015] [1-1-2. Configuration of the electrical box support member and the electrical box] FIG. 2 is a perspective view of the electrical box 20. FIG. 3 is a perspective view of the electrical box 20 when pulled out. FIG. 4 is a cross-sectional view taken on the IV plane as viewed from the right side of FIG. 2. FIG. 5 is a cross-sectional view taken on the V plane as viewed from the right side of FIG. 2. FIG. 6 is an enlarged view of the range indicated by VI in FIG. 2. FIG. 7 is an enlarged view of the range indicated by VII in FIG. 3.

[0016] As shown in FIG. 1, the main body 2 is provided with legs 9 on the lower surface of the lower bottom plate 5. The main body 2 has a lower space 10 at the lower part with a height equal to that of the legs 9. An electrical box 20 is attached to the lower surface side of the bottom plate 5 of the main body 2 adjacent to the right leg 9. The electrical box 20 houses various electrical components. The electrical box 20 includes an electrical box main body 21 and an electrical box support member 22 as shown in FIGS. 2 and 3.

[0017] The electrical box main body 21 is attached to the electrical box support member 22. The electrical box support member 22 is made of sheet metal. The electrical box support member 22 includes a plate portion 23 that extends in the horizontal direction, and a front flange portion 24 and a rear flange portion 25 on the front and rear sides respectively.

[0018] The front flange portion 24 is formed by bending upward from the plate portion 23 and further bending forward, thereby being configured as a substantially L-shaped flange. The rear flange portion 25 is formed by bending upward from the plate portion 23 and further bending rearward, thereby being configured as a substantially L-shaped flange.

[0019] The front flange portion 24 and the rear flange portion 25 are fixed to the bottom plate 5 by a fixture 26. A pair of rail portions 28 are respectively formed on the left and right sides of the electrical box support member 22. The rail portions 28 are formed by bending the left and right side edges of the plate portion 23 upward respectively. As shown in FIG. 6, the front end of the rail portion 28 is provided with a protruding portion 33 that protrudes forward beyond the front flange portion 24 and the runner portion 46 when the electrical box body 21 described later is housed.

[0020] The protruding portion 33 includes a guide portion 29, a protruding portion 30, and a tapered portion 31. As shown in FIG. 4, the front end of the rail portion 28 extending in the vertical direction is formed with a guide portion 29 that slopes backward. As shown in FIGS. 4 and 6, a protruding portion 30 is formed at the upper end of the guide portion 29.

[0021] The protruding portion 30 is formed so as to protrude upward from the upper end side of the rail portion 28. The front side of the protruding portion 30 is inclined so as to rise rearward, and the rear side is formed substantially perpendicular to the upper end side.

[0022] The tapered portion 31 is formed so that the protruding portion 33 tapers toward the front. More specifically, the tapered portion 31 is formed so as to be inclined from the front end of the rail portion 28 toward the front and inward in the left-right direction. The tapered portion 31 is integrally formed with the plate portion 23 and is located in the same plane as the plate portion 23. As shown in FIG. 5, the round portion 32 at the rear end of the rail portion 28 is formed up to the vertically extending surface of the rear flange portion 25 and is formed in a round shape.

[0023] As shown in FIG. 3, the electric cabinet body 21 formed of sheet metal is configured as a box-shaped member having an opening 40 that opens vertically upward, wall portions on the front, rear, left, and right, and a bottom portion at the bottom. Note that opening vertically upward does not mean that the surface constituting the opening 40 is completely horizontal, and also includes a configuration in which the surface constituting the opening 40 is inclined in the front, rear, left, and right directions and the opening 40 faces upward. The electric cabinet body 21 has side walls 41 on the left and right, a rear wall 42 on the rear side, a front wall 43 and a front cover member 45 on the front side, and a bottom plate 44 at the bottom. The interior of the electric cabinet body 21 refers to the space surrounded by the side walls 41, the front cover member 45, the rear wall 42, and the bottom plate 44.

[0024] The electric cabinet body 21 is configured to be pullable forward with respect to the electric cabinet support member 22. The states of the electric cabinet body 21 mainly include a storage state in which it is pushed into the depth direction of the electric cabinet support member 22 shown in FIG. 2, that is, backward, a pull-out state in which only the front portion of the electric cabinet body 21 shown in FIG. 3 is pulled out, and a take-out state in which the entire electric cabinet body 21 is pulled out.

[0025] [1-1-3. Configuration of the pull-out mechanism] In FIG. 6, the front end of the pull-out mechanism 48 is shown enlarged. In FIG. 7, the notch portion 47 is shown enlarged. As shown in FIGS. 2, 4, 6, and 7, runner portions 46 are formed at the upper ends of the left and right side walls 41 of the electric cabinet body 21, respectively. The runner portions 46 are bent inwardly of the electric cabinet body 21. As shown in FIG. 7, a notch portion 47 is formed across the runner portions 46 and the side walls 41 at the central portion of the electric cabinet body 21 in the front-rear direction. The notch portion 47 is notched to a dimension such that the protrusion 30 of the rail portion 28 can be inserted therethrough.

[0026] The runner portion 46 of the electrical box body 21 abuts against the rail portion 28 of the electrical box support member 22. The runner portion 46 and the rail portion 28 constitute a pulling-out mechanism 48 of the electrical box body 21. Thereby, the electrical box support member 22 supports the electrical box body 21 so as to be pullable out from the electrical box support member 22. Further, the electrical box support member 22 also functions as a lid member that covers the opening 40 of the box-shaped electrical box body 21. When the electrical box body 21 is pulled out, the notch portion 47 corresponds to the state of being pulled out until the protrusion portion 30 of the rail portion 28 is caught.

[0027] As described above, particularly as shown in FIGS. 3, 6, and 7, the pulling-out mechanism 48 is constituted by the runner portion 46 provided in the electrical box body 21 and the rail portion 28 provided in the electrical box support member 22. A protrusion portion 30 is formed at the front end of the runner portion 46, and the rail portion 28 is formed with a notch portion 47 at the front-rear center position where the protrusion portion 30 is caught. According to this, only the front side of the electrical box body 21 can be easily pulled out.

[0028] As shown in FIGS. 2 and 3, the rail portion 28 of the electrical box support member 22 is bent upward, and the runner portion 46 of the electrical box body 21 is bent inward in the left-right direction. The rail portion 28 and the runner portion 46 overlap to constitute the pulling-out mechanism 48. Even when drain water drops onto the plate portion 23 of the electrical box support member 22, since the rail portion 28 is bent upward, it is possible to suppress the drain water from entering the interior of the electrical box body 21.

[0029] Even when drain water adheres to the pulling-out mechanism 48, since the rail portion 28 and the runner portion 46 are bent and the pulling-out mechanism 48 has an intricate structure, it is possible to suppress the drain water from entering the interior of the electrical box body 21.

[0030] Furthermore, the front end of the rail portion 28 of the electrical box support member 22 is formed to protrude forward more than the front end of the runner portion 46 of the electrical box body 21, and the rail portion 28 further has a tapered portion 31 formed in a tapered shape at the front end. According to this, the visibility of the electrical box support member 22 at the lower front side of the storage 1 is improved by the rail portion 28 of the electrical box support member 22, and the assemblability of the electrical box body 21 is improved by the tapered portion 31. Therefore, it becomes easier to attach the electrical box body 21. Further, since the front end of the rail portion 28 functions as an eaves, the waterproof property of the electrical box body 21 is improved.

[0031] [1-1-4. Structure of Electrical Box Fixing Member] The cross-sectional view of FIG. 5 shows the location passing through the electrical box fixing member 60. As shown in FIG. 5, an electrical box fixing member 60 is attached to the rear flange portion 25 of the electrical box support member 22 by a fixture 63. The electrical box fixing member 60 is attached to the rear side of the surface extending in the vertical direction of the rear flange portion 25.

[0032] The electrical box fixing member 60 is formed in a substantially L shape and includes a leaf spring portion 61 formed to extend forward. A rectangular notch portion 62 facing the leaf spring portion 61 is formed in the plate portion 23 of the electrical box support member 22.

[0033] The leaf spring portion 61 is formed by bending and deforming a sheet metal, and is configured as a spring using the elasticity of the sheet metal. The leaf spring portion 61 is an example of a spring portion. The leaf spring portion 61 has a first peak portion 64 bent upward from a fixing portion 63A attached to the rear flange portion 25, a second peak portion 65 bent downward, and a third peak portion 66 bent upward. The first peak portion 64, the second peak portion 65, and the third peak portion 66 are configured such that the bending angles are gradually relaxed in this order.

[0034] The upper end of the rear wall 42 of the electrical box body 21 in the stored state abuts against the second peak portion 65. Further, when the electrical box body 21 at the time of pulling out is pushed in for storage, the upper end of the rear wall 42 of the electrical box body 21 is guided to the second peak portion 65 by a guide surface portion 66A extending upward and forward from the third peak portion 66.

[0035] In this way, the electrical box body 21 configured to be pullable forward is attached to the rear flange portion 25 of the electrical box support member 22 during storage, caught by the resilient electrical box fixing member 60, and pressed by the electrical box fixing member 60. According to this, the storage state of the electrical box body 21 can be maintained without using fixtures such as screws and bolts. As a result, the number of components constituting the electrical box 20 and the man-hours for assembling the electrical box 20 can be reduced.

[0036] [1-1-5. Configuration of the front cover and front wall of the electrical box body] FIG. 8 is an exploded perspective view of the electrical box body 21 and the front cover member 45. The electrical box body 21 includes a front cover member 45 in front of the front wall 43. The front cover member 45 is provided with front cover fixtures 70 on the left and right and is configured to be detachable from the electrical box body 21. The pair of left and right side walls 41 are provided with side wall flange portions 74 that are bent inward at the front ends.

[0037] The front cover fixture 70 is a resin rivet composed of a head portion 71 and a leg portion 72. The leg portion 72 is inserted through the through hole 73 of the front cover member 45 and the through hole 75 of the side wall flange portion 74, and the head portion 71 is inserted through the leg portion 72, whereby the front cover member 45 is fixed to the side wall 41.

[0038] The front cover member 45 is provided with an upper cover portion 76 at the upper end. The upper cover portion 76 is bent rearward from the upper end of the front cover member 45 and further bent upward, and is configured in a substantially L shape. The upper cover portion 76 is formed to face the front flange portion 24 when the electrical box body 21 is stored.

[0039] Next, the front wall 43 will be described in detail. As shown in FIGS. 4 and 8, the front wall 43 is provided at the front end of the bottom plate 44. The bottom plate 44 formed integrally with the left and right side walls 41 is formed such that the front end overlaps the rear surface of the front flange portion 24 in the front-rear direction.

[0040] As shown in FIG. 4, the front wall 43 is provided with front wall flange portions 77 at its left and right ends. The left and right front wall flange portions 77 are fixed to the respective left and right side walls 41 by fixtures 78. Although only the left front wall flange portion 77 and the fixture 78 are shown in FIG. 4, the right side has the same configuration.

[0041] The lower end of the front wall 43 is bent rearward and is arranged to cover the front end of the bottom plate 44 by the lower end of the front wall 43. The front wall 43 is an example of the first wall. As shown in FIG. 4, a first seal member 79 is attached to the lower inner surface of the front cover member 45. As shown in FIGS. 4 and 8, a second seal member 80 is attached to the lower outer surface of the front wall 43.

[0042] The first seal member 79 and the second seal member 80 are made of synthetic sponge, but are not limited thereto, and any member that is soft and elastic may be used. For example, a cushioning material or packing may be used. The first seal member 79 and the second seal member 80 are examples of the "seal member".

[0043] The first seal member 79 is arranged so as to be shifted upward from the second seal member 80. In the state where the front cover member 45 is attached, as shown in FIG. 4, the first seal member 79 and the second seal member 80 are arranged to contact each other and block the second opening 81 between the front cover member 45 and the front wall 43. The second opening 81 is an example of the opening. The front cover member 45 constitutes a handle 82 at a position below the first seal member 79.

[0044] [1-1-6. Electrical components in the electrical box] FIG. 9 is a perspective view of the electrical box body 21 as viewed from the left. FIG. 10 is an enlarged side view of the rear portion of the electrical box body 21. FIG. 11 is a plan view of the electrical box body 21. In FIG. 11, the wiring 130 and the power supply wiring 131, which were omitted in the other figures, are shown. Also, in FIG. 11, the state where the front cover member 45 is disassembled is shown.

[0045] The electrical equipment box body 21 includes, inside thereof, a first substrate 90, a second substrate 91, a relay section 92, and a terminal block 93. The wiring 130, the power supply wiring 131, the first substrate 90, the second substrate 91, the relay section 92, and the terminal block 93 are examples of the electrical components of the electrical equipment box 20.

[0046] The first substrate 90 is disposed behind the terminal block 93 and to the left of the electrical equipment box body 21. The first substrate 90 is mainly a substrate related to power supply. The second substrate 91 is disposed from the inner surface of the front wall 43 to the front surface of the relay section 92 on the right. The second substrate 91 is mainly a substrate related to the communication of the storage compartment 1. The second substrate wiring 132 among the wirings 130 is connected to the second substrate 91. The wiring 130 is composed of a plurality of electric wires and is connected to the first substrate 90, the second substrate 91, and the relay section 92, or other electrical components.

[0047] The second substrate 91 includes a communication connection portion 123 to which a communication member is connected. The communication connection portion 123 is disposed at the front end of the second substrate 91. The connection work for connecting a communication member to the communication connection portion 123 is performed during the on-site construction of the storage compartment 1. Since the communication connection portion 123 is disposed on the side in the pulling-out direction of the electrical equipment box body 21, by pulling out only one end side in the pulling-out direction of the electrical equipment box body 21, the communication connection portion 123 of the electrical equipment box body 21 is exposed, and it is not necessary to remove the lid, and the shipping inspection and the connection work of the on-site construction related to the electrical equipment box 20 can be facilitated. The second substrate 91 includes an antenna, a wireless communication circuit, etc. as a communication section, and communicates with each part of the storage compartment 1 or a device outside the storage compartment 1 according to the control of the control device included in the storage compartment 1. The communication member connected to the communication connection portion 123 during the on-site construction is, for example, a flexible flat cable. Note that the communication member may be a member corresponding to the specifications of the second substrate 91 and the communication connection portion 123 and can be appropriately changed.

[0048] The relay section 92 is configured to be able to connect a plurality of terminals. The relay section 92 is disposed at two corners on the rear side of the electrical equipment box body 21. Note that the relay section 92 may be disposed at either one of the two rear corners, or may not be disposed.

[0049] As shown in FIG. 10, the relay unit 92 is a substantially rectangular parallelepiped member and has claw portions 94 at its upper and lower portions respectively. The claw portions 94 are formed to taper toward the tip and have notch holes 95 formed by being notched from the tip toward the inside of the relay unit 92. The upper claw portion 94 is fixed to the side wall 41 through a fixture 96 in the notch hole 95.

[0050] The lower claw portion 94 is inserted into insertion holes 97 formed at the corners of the side wall 41 and the bottom plate 44. As shown in FIGS. 5 and 10, the insertion holes 97 are configured as long hole-shaped through holes, and two of them are formed corresponding to the two tip portions 94A of the claw portion 94. The relay unit 92 is fixed to the inner surface of the side wall 41 by one fixture 96 and the insertion holes 97. Note that the relay unit 92 is omitted in FIG. 5 for the explanation of the insertion holes 97.

[0051] In this way, the relay unit 92 provided inside the electric cabinet body 21 has claw portions 94 protruding downward, and the claw portions 94 are inserted into the insertion holes 97 formed in the electric cabinet body 21. According to this, fixtures such as screws and bolts for fixing the relay unit 92 to the electric cabinet body 21 can be reduced. As a result, the number of parts constituting the electric cabinet 20 and the man-hours for assembling the electric cabinet 20 can be reduced.

[0052] A wiring hole 98 is formed in the side wall 41 on the left side of the electric cabinet body 21 at a position in front of the relay unit 92. The wiring hole 98 allows a wiring 130 connected from a member outside the electric cabinet body 21 to members inside the electric cabinet body 21 such as the first substrate 90, the second substrate 91, the relay unit 92, and the terminal block 93 to be inserted therethrough.

[0053] A bundling band 99 is provided on the side wall 41 on the left side of the electric cabinet body 21 at a position in front of the wiring hole 98. Further, a wiring clamp 100 is provided at the front portion of the side wall 41 on the left side of the electric cabinet body 21. Note that the wiring clamp 100 may be provided on the bottom surface 44 of the electric cabinet body 21.

[0054] [1-1-7. Configuration of Terminal Block] As shown in FIGS. 4, 8, and 11, a terminal block support member 110 is provided at the upper left part of the front wall 43. The cross-sectional view of FIG. 4 shows the location passing through the terminal block 93. The terminal block 93 and the terminal block support member 110 are arranged on the front side of the electrical cabinet body 21. The front side in this embodiment is an example of one end side in the pulling-out direction of the electrical cabinet body 21. The terminal block support member 110 has a locking hole 118 at the corner on the side of the second substrate 91 on the upper surface. As shown in FIG. 11, a binding band 117 with a locking portion for binding a part of the second substrate wiring 132 is inserted through the locking hole 118.

[0055] The terminal block support member 110 has a through hole 112 on the upper surface into which a locking portion 111 formed at the lower part of the terminal block 93 is fitted, as shown in FIG. 4. Although the upper surface of the terminal block support member 110 is formed to extend in a substantially horizontal direction, it is not limited thereto, and for example, it may be inclined so as to rise backward.

[0056] The terminal block support member 110 is fixed by two fixtures 116. The front flange portion 113 formed on the front side of the terminal block support member 110 is fixed to the front wall 43 by one of the fixtures 116. The side flange portion 114 formed on the left side of the terminal block support member 110 is fixed to the left side wall 41 by the other fixture 116.

[0057] The terminal block support member 110 has a foot plate portion 115 that is bent downward on the right side, as shown in FIGS. 4 and 8, and the lower end of the foot plate portion 115 abuts against the bottom plate 44. Thereby, even when a strong downward stress is applied to the terminal block 93, deformation of the terminal block support member 110 can be suppressed. In FIG. 4, the foot plate portion 115 is shown by a dashed line. The terminal block 93 is arranged above the inside of the electrical cabinet body 21, that is, on the side close to the upper end of the electrical cabinet body 21, by the terminal block support member 110. Also, the terminal block 93 is arranged on the front side inside the electrical cabinet body 21 by the terminal block support member 110 attached to the front wall 43.

[0058] The terminal block 93 is configured as a quick-connect type terminal block. In a quick-connect type terminal block, unlike a screw type terminal block, tools such as a driver are not required, so wiring connection is easy. Note that the terminal block 93 may be a screw type terminal block or a connection type terminal block. The terminal block 93 has a front connection part 120 and a rear connection part 121. The front connection part 120 and the rear connection part 121 are formed on the side part of the terminal block 93.

[0059] The rear connection part 121 is provided with holes through which terminals or metal wires can be inserted. The wiring 130 connected to the rear connection part 121 is provided at the manufacturing stage of the storage 1. The wiring 130 connected to the rear connection part 121 is drawn from the wiring hole 98 and connected to the first substrate 90, the second substrate 91, and the relay part 92. The wiring 130 is supported by the binding band 99.

[0060] The front connection part 120 is provided with holes through which terminals or metal wires can be inserted. The power supply wiring 131 connected to the front connection part 120 is connected during the installation work of the storage 1. Since the power supply wiring 131 is configured as a single wire, it has less flexibility than a so-called flexible wire. Part or all of the power supply wiring 131 connected to the front connection part 120 is configured as wiring for connecting to a power supply provided at the installation location.

[0061] Furthermore, the terminal block 93 has an inspection hole 122 on the upper surface. The inspection hole 122 is mainly used as an insertion hole for the terminals of an electrical measuring device. The power supply wiring 131 extending from the front connection part 120 of the terminal block 93 is routed outside the electrical box body 21 between the first seal member 79 and the second seal member 80 and is supported by the wiring clamp 100. The terminal block 93 is arranged such that the front connection part 120 is located on the side of the second opening 81.

[0062] [1-2. Action, etc.] In particular, as shown in FIG. 3, a terminal block 93 is disposed on the drawer-out direction side of the electrical box body 21, that is, on the front side of the storage 1. If the terminal block 93 is not disposed on the drawer-out direction side of the electrical box body 21 but is disposed in the center or the rear side of the electrical box body 21, when connecting wiring to the terminal block 93 or performing maintenance on the wiring connected to the terminal block 93, etc., it is necessary to pull out the entire electrical box body 21.

[0063] During on-site construction of the storage 1, in particular, the routing work of the power wiring 131 is carried out. Also, when the storage 1 is shipped, the storage 1 is inspected by connecting the terminals of the electrical measuring device to the terminal block 93 of the electrical box body 21. In the present embodiment, by pulling out only the front part without pulling out the entire electrical box body 21, the routing of the power wiring 131, the inspection of the storage 1, etc. can be performed.

[0064] Further, the upper part of the electrical box body 21 is open, and the front connection part 120 of the terminal block 93 is configured to be accessible from above the electrical box body 21 when pulled out. Since the electrical box 20 is installed below the storage 1, from the viewpoint of workability, the members disposed inside the electrical box 20 are preferably disposed so as to be accessible from above the electrical box body 21.

[0065] In particular, as shown in FIGS. 4 and 11, the power wiring 131 connected to the terminal block 93 is routed outside the electrical box body 21 via between the upper end of the front wall 43, the first seal member 79, and the second seal member 80. If the power wiring 131 is routed in a direction other than the front direction from the front connection part 120 and is routed via the opening formed in the side wall 41 of the electrical box body 21, the only place through which the power wiring 131 passes until it is pulled out to the outside of the electrical box body 21 is the opening of the side wall 41.

[0066] In this case, compared with the routing of the power wiring 131 in the present embodiment, a relatively large tension is applied to the power wiring 131 at the position relative to the front connection part 120. In the present embodiment, the load applied to the power wiring 131 at the position of the front connection part 120 can be suppressed.

[0067] As shown in FIG. 4, the first seal member 79 and the second seal member 80 enable the power supply wiring 131 to be drawn out of the electrical box body 21, while improving the dustproof property of the electrical box 20.

[0068] As shown in FIG. 4, the electrical box body 21 is configured to be pullable forward of the storage 1, and the terminal block 93 is disposed such that it is shifted rearward from the front surface of the storage 1 by the amount of the upper lid portion 76 of the front lid member 45. More specifically, the rear edge of the upper lid portion 76 overlaps with the front wall 43 in the vertical direction when the electrical box body 21 is stored. According to this, although drain water generated in the display chamber 3 is likely to drop on the front surface side of the storage 1, since the terminal block 93 is disposed so as to be shifted rearward from the front end of the electrical box body 21, the waterproof property of the terminal block 93 can be improved.

[0069] [1-3. Effects, etc.] As described above, the storage 1 according to the present embodiment includes an electrical box 20 having an electrical box body 21 that houses electrical components and is pullable.

The electrical box body 21 has an upward opening, and a terminal block 93 to which the power supply wiring 131 is connected is housed in the electrical box body 21. The terminal block 93 is disposed on the front side (one end side in the pulling-out direction) of the electrical box body 21. According to this configuration, since the terminal block 93 is disposed on the pulling-out direction side of the electrical box body 21, by pulling out only one end side in the pulling-out direction of the electrical box body 21, the terminal block 93 of the electrical box body 21 is exposed, and there is no need to remove the lid. Therefore, the shipping inspection and connection work for on-site construction related to the electrical box 20 can be facilitated.

[0070] Further, the electrical box body 21 includes a detachable front lid member 45 (lid member) on the front side (one end side), a front wall 43 (first wall) is formed at the front end (one end) of the bottom plate 44 of the electrical box body 21, a second opening 81 (opening) is formed between the front wall 43 and the front lid member 45, and a seal member for closing the second opening 81 is provided. According to this configuration, while enabling wiring to be drawn out from the electrical components housed in the electrical box body 21 through the second opening 81, the dustproof property of the electrical box body 21 can be improved by the seal member.

[0071] Further, a first seal member 79 is provided on the front cover member 45, a second seal member 80 is provided on the front wall 43, and the lower surface of the first seal member 79 is located above the lower surface of the second seal member 80. According to this configuration, the position below the first seal member 79 of the front cover member 45 functions as a handle 82 when pulling out the electrical box body 21, making it easier to pull out the electrical box body 21.

[0072] Also, the electrical box body 21 includes a terminal block support member 110 that supports the terminal block 93. The terminal block support member 110 is provided on the front wall 43, and the terminal block 93 is disposed on the upper surface of the terminal block support member 110. According to this configuration, since the terminal block 93 is disposed on the upper side inside the electrical box body 21, the shipping inspection and on-site construction connection work related to the electrical box 20 can be further facilitated.

[0073] Also, a wiring clamp 100 (wiring support portion) is provided on the outer surface of the electrical box body 21. The power wiring 131 is connected to the second opening 81 side of the terminal block 93, drawn out from the terminal block 93 to the outside of the electrical box body 21 via the second opening 81, and supported by the wiring clamp 100. According to this configuration, since the connection location of the power wiring 131 to the terminal block 93 is on the same side as the direction in which the power wiring 131 is drawn out to the outside of the electrical box body 21, and also, the power wiring 131 drawn out from the terminal block 93 abuts against the corner between the terminal block support member 110 and the front wall 43 even when tension is applied to the power wiring 131, the load applied to the connection location of the power wiring 131 can be suppressed.

[0074] Also, the terminal block 93 is configured as a quick-connection type. According to this configuration, compared with the screw type, no tools such as a driver are required, so the shipping inspection and on-site construction connection work can be facilitated.

[0075] In addition, the electrical equipment box 20 is provided with an electrical equipment box support member 22. The electrical equipment box support member 22 is provided with a front flange portion 24 (first flange portion) on the front side and a rear flange portion 25 (second flange portion) on the rear side (the other end side).

[0076] In addition, a rail portion 28 extending in the pulling-out direction is formed on the electrical equipment box support member 22, and a runner portion 46 extending in the pulling-out direction is formed on the electrical equipment box body 21. The rail portion 28 and the runner portion 46 constitute a pulling-out mechanism 48 of the electrical equipment box 20. A notch portion 47 is formed in the central portion of the rail portion 28, and a protrusion portion 30 is formed on the front end side of the runner portion 46. According to this configuration, when the electrical equipment box body 21 is pulled out sufficiently during the shipping inspection or on-site construction related to the terminal block 93, the protrusion portion 30 is caught by the notch portion 47, so that the electrical equipment box body 21 can be easily put into the pulled-out state.

[0077] In addition, a relay portion 92 capable of connecting a plurality of terminals is housed in the electrical equipment box body 21. The relay portion 92 is provided with two claw portions 94. One upper claw portion 94 is fixed to the electrical equipment box body 21 by a relay portion fixing tool 96 (fixing tool), and the other lower claw portion 94 is inserted into an insertion hole 97 formed in the electrical equipment box body 21. According to this configuration, the fixtures used for fixing the relay portion 92 can be reduced, and the man-hours for assembling the electrical equipment box 20 can be reduced.

[0078] In addition, the terminal block 93 is disposed on the storage direction side opposite to the pulling-out direction from the front wall 43. The front cover member 45 is provided with an upper cover portion 76 that is bent toward the storage direction side. When the electrical equipment box body 21 is stored, the edge of the upper cover portion 76 is disposed at a position overlapping with the front wall 43 in the vertical direction.

Specifically, even if drain water drips from the gap between the upper lid portion 76 and the front flange portion 24, the drain water is likely to drip in front of the front wall 43.

[0079] Further, the rail portion 28 is formed by bending the side of the electric cabinet support member 22 formed of sheet metal upward, and the runner portion 46 is formed by bending the side wall 41 of the electric cabinet main body 21 inward. According to this configuration, since the rail portion 28 and the runner portion 46 are formed by bending and combined, it is difficult for drain water or the like to penetrate, and the waterproof property of the electric cabinet 20 can be improved.

[0080] Further, the rail portion 28 has a protruding portion 33 formed so as to protrude in the pulling direction beyond one end of the runner portion 46 on one end side, and the protruding portion 33 has a tapered portion 31 formed so as to taper toward the pulling direction. According to this configuration, the visibility of the protruding portion 33 in front of the storage cabinet 1 is high, and the protruding portion 33 and the tapered portion 31 make it easy to assemble when storing the electric cabinet main body 21 during extraction, and the attachment of the electric cabinet main body 21 to the electric cabinet support member 22 can be facilitated.
