[0063] When the inventors conceived of the present disclosure, as in Patent Document 1, there was a technology for housing electrical installation components in an electrical installation box body provided in an electrical installation box and being able to be pulled out. However, in the prior art, the inventors found the following problems: The terminal block is not arranged in the pulling-out direction of the electrical installation box body, and it is necessary to pull out to the part on the opposite side of the pulling-out direction of the electrical installation box body, or it is necessary to take out the entire electrical installation box body, and the factory inspection of the electrical installation box and the connection work during on-site construction are not easy. To solve this problem, the subject matter of the present disclosure is constituted.

[0064] Therefore, the present disclosure provides a storage that can easily perform the factory inspection of the electrical installation box and the connection work during on-site construction.

[0065] (Embodiment 1)

[0066] Hereinafter, embodiments will be described in detail with reference to the drawings. However, sometimes detailed descriptions that are unnecessary will be omitted. For example, sometimes detailed descriptions of well-known matters will be omitted, or repeated descriptions of substantially the same structures will be omitted.

[0067] In addition, the 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 by these.

[0068] [1-1. Structure]

[0069] [1-1-1. Structure of the display cabinet]

[0070] In each figure, the symbol FR appropriately shown indicates the front of the storage chamber 1 and the electrical installation box 20 in the installed state, the symbol UP indicates the upper side of the storage chamber 1 and the electrical installation box 20, and the symbol LH indicates the left side of the storage chamber 1 and the electrical installation box 20. In the following description, each direction is the direction along these directions.

[0071] Moreover, in the present embodiment, the front is an example of the direction in which the electrical installation box main body 21 is pulled out, and the rear is an example of the direction in which the electrical installation box main body 21 is stored.

[0072] Figure 1 is the front view of the storage chamber 1 of Embodiment 1.

[0073] The storage chamber 1 of Embodiment 1 is an open display cabinet having a front opening and installed in a store such as a convenience store or a supermarket.

[0074] The storage chamber 1 is composed of a main body 2 having a front opening and covering the upper surface, the back surface, the side surfaces, and the lower surface, and a display chamber 3. The main body 2 has a heat-insulating wall portion 4, and an inner panel 6 is provided inside the display chamber 3.

[0075] The front of the display chamber 3 is open, and inside the display chamber 3, a pair of brackets that are detachably mounted on columns and a shelf board 8 supported by the brackets are provided. The columns are provided on the front side of the inner panel 6 located on the back side of the display chamber 3. Further, it is configured to display goods on the upper surface of the shelf board 8. That is, the storage chamber 1 can store items.

[0076] A compressor, a condenser, a fan, etc. that constitute a refrigeration cycle are arranged inside the storage chamber 1, and an evaporator that constitutes a refrigeration system is arranged inside a cold air duct located on the rear side of the inner panel 6. By driving the compressor and the fan, the cold air after heat exchange with the evaporator rises inside the cold air duct and is discharged toward the front opening. By means of the cold air discharged to the front opening, an air curtain formed by the cold air is formed at the front opening, and a part of the air curtain of the cold air circulates inside the display chamber 3.

[0077] In addition, the refrigeration cycle is not limited to the built-in type of display cabinet. The storage chamber 1 may also be a separate type of display cabinet in which the compressor, condenser, fan, etc. that constitute the refrigeration cycle are not arranged inside the main body 2, but are provided separately from the main body 2 with an outdoor unit having a compressor, condenser, fan, etc.

[0078] [1-1-2. Structure of the electrical installation box support member and the electrical installation box]

[0079] Figure 2 is a perspective view of the electrical installation box 20. Figure 3 is a perspective view of the electrical installation box 20 when pulled out. Figure 4 is from Figure 2 a cross-sectional view taken along plane IV as viewed from the right side of Figure 5 is from Figure 2 a cross-sectional view taken along plane V as viewed from the right side of

[0080] Figure 6 is Figure 2 an enlarged view of the range shown by VI of Figure 7 is Figure 3 an enlarged view of the range shown by VII of

[0081] As Figure 1 shown, the main body 2 is provided with feet 9 on the lower surface of the bottom plate 5 at the lower part. The main body 2 has a lower space 10 corresponding to the height of the feet 9 at the lower part. On the lower side of the bottom plate 5 of the main body 2, an electrical installation box 20 is installed adjacent to the right foot 9. The electrical installation box 20 houses various electrical installation components. As Figure 2 and Figure 3 shown, the electrical installation box 20 includes an electrical installation box main body 21 and an electrical installation box support member 22.

[0082] The electrical installation box main body 21 is installed on the electrical installation box support member 22.

[0083] The electrical installation box support member 22 is made of a metal plate. The electrical installation 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.

[0084] The front flange portion 24 is bent upward from the plate portion 23 and then bent forward, thereby forming a flange in a substantially L shape.

[0085] The rear flange portion 25 is bent upward from the plate portion 23 and then bent backward, thereby forming a flange in a substantially L shape.

[0086] The front flange portion 24 and the rear flange portion 25 are fixed to the bottom plate 5 by fixing members 26.

[0087] A pair of rail portions 28 are respectively formed on the left and right sides of the support member 22 of the electrical installation box. The rail portions 28 are formed by bending the left and right side edges of the plate portion 23 upward respectively.

[0088] As Figure 6 shown, the rail portion 28 has a front flange portion 24 and a protruding portion 33 at the front end, and the protruding portion 33 is formed to protrude forward from a slide portion 46 when the main body 21 of the electrical installation box described later is received.

[0089] The protruding portion 33 includes a guiding portion 29, a protruding portion 30, and a wedge portion 31.

[0090] As Figure 4 shown, a guiding portion 29 is formed at the front end of the rail portion 28 extending in the vertical direction in a manner inclined backward. As Figure 4 and Figure 6 shown, a protruding portion 30 is formed at the upper end of the guiding portion 29.

[0091] The protruding portion 30 is formed to protrude upward from the upper end edge of the rail portion 28. The front side of the protruding portion 30 is inclined to stand backward, and the rear side is formed substantially perpendicular to the upper end edge.

[0092] The wedge portion 31 is formed in such a way that the protruding portion 33 tapers forward. More specifically, the wedge portion 31 is formed to incline forward and inward in the left - right direction from the front end of the rail portion 28. The wedge portion 31 is integrally formed with the plate portion 23 and is in the same plane as the plate portion 23.

[0093] As Figure 5 shown, an arc portion 32 at the rear end of the rail portion 28 is formed on a surface extending in the vertical direction of the rear flange portion 25 and is formed in an arc shape.

[0094] As Figure 3 shown, the main body 21 of the electrical installation box formed of a metal plate is configured as a box - shaped component having an opening portion 40 opening vertically upward, having wall portions on the front, rear, left, and right, and having a bottom portion below. In addition, the vertically upward opening does not mean that the surface constituting the opening portion 40 is completely horizontal, and also includes a structure in which the surface constituting the opening portion 40 is inclined in the front - rear - left - right direction and the opening portion 40 faces upward.

[0095] The main body 21 of the electrical installation box 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 on the lower portion. The interior of the main body 21 of the electrical installation box refers to the space surrounded by the side walls 41, the front cover member 45, the rear wall 42, and the bottom plate 44.

[0096] The main body 21 of the electrical installation box is configured to be able to be pulled forward relative to the electrical installation box support member 22. As the states of the main body 21 of the electrical installation box, there are mainly Figure 2 when it is pushed into the rear in the depth direction of the electrical installation box support member 22 as shown, Figure 3 when only the front part of the main body 21 of the electrical installation box is pulled out as shown, and when the entire main body 21 of the electrical installation box is pulled out for removal.

[0097] [1-1-3. Structure of the pulling-out mechanism]

[0098] In Figure 6 , the front end of the pulling-out mechanism 48 is shown enlarged. In Figure 7 , the notch portion 47 is shown enlarged.

[0099] As shown in Figure 2 , Figure 4 , Figure 6 and Figure 7 , slideway portions 46 are formed at the upper ends of the left and right side walls 41 of the main body 21 of the electrical installation box respectively. The slideway portions 46 are formed to be curved toward the inside of the main body 21 of the electrical installation box. As shown in Figure 7 , at the central portion in the front-rear direction of the main body 21 of the electrical installation box, a notch portion 47 is formed across the slideway portions 46 and the side walls 41. The notch portion 47 is cut to a size that allows the protruding portion 30 of the rail portion 28 to penetrate and insert.

[0100] The slideway portion 46 of the main body 21 of the electrical installation box abuts against the rail portion 28 of the electrical installation box support member 22. The slideway portion 46 and the rail portion 28 constitute the pulling-out mechanism 48 of the main body 21 of the electrical installation box.

[0101] Thereby, the electrical installation box support member 22 supports the main body 21 of the electrical installation box so that it can be pulled out from the electrical installation box support member 22. Also, the electrical installation box support member 22 functions as a cover member that covers the opening portion 40 of the main body 21 of the electrical installation box configured as a box.

[0102] The pulling-out of the main body 21 of the electrical installation box corresponds to the state where the protruding portion 30 of the rail portion 28 is caught by the notch portion 47.

[0103] In this way, especially as shown in Figure 3 , Figure 6 and Figure 7 , the pulling-out mechanism 48 is constituted by the slideway portion 46 provided in the main body 21 of the electrical installation box and the rail portion 28 provided in the electrical installation box support member 22. A protruding portion 30 is formed at the front end of the rail portion 28, and a notch portion 47 for catching the protruding portion 30 is formed at the position in the front-rear center of the slideway portion 46.

[0104] Thus, it is easy to pull out only the front side of the electrical installation box body 21.

[0105] As Figure 2 and Figure 3 shown, the rail portion 28 of the electrical installation box support member 22 is bent upward, and the slide portion 46 of the electrical installation box body 21 is bent inward in the left - right direction. The rail portion 28 and the slide portion 46 overlap to form a pull - out mechanism 48.

[0106] Even when the drained water falls onto the plate portion 23 of the electrical installation box support member 22, since the rail portion 28 is bent upward, it is possible to prevent the drained water from entering the interior of the electrical installation box body 21.

[0107] Even when the drained water adheres to the pull - out mechanism 48, since the rail portion 28 and the slide portion 46 are bent, and the pull - out mechanism 48 has a complicated structure, it is possible to prevent the drained water from entering the interior of the electrical installation box body 21.

[0108] In addition, the front end of the rail portion 28 of the electrical installation box support member 22 is formed to protrude forward compared to the front end of the slide portion 46 of the electrical installation box body 21, and the rail portion 28 has a wedge - shaped portion 31 formed in a wedge shape at the front end.

[0109] Thus, by means of the rail portion 28 of the electrical installation box support member 22, the visual confirmation of the electrical installation box support member 22 at the lower front side of the storage 1 is improved, and by means of the wedge - shaped portion 31, the assemblability of the electrical installation box body 21 is improved.

[0110] Therefore, it is easy to install the electrical installation box body 21. Moreover, since the front end of the rail portion 28 functions as an eaves, the waterproof property of the electrical installation box body 21 is improved.

[0111] [1 - 1 - 4. Structure of Electrical Installation Box Fixing Member]

[0112] In Figure 5 the cross - sectional view, the part passing through the electrical installation box fixing member 60 is shown.

[0113] As Figure 5 shown, on the rear flange portion 25 of the electrical installation box support member 22, the electrical installation box fixing member 60 is installed by a fixing member 63. The electrical installation box fixing member 60 is installed on the rear side of the surface extending in the vertical direction of the rear flange portion 25.

[0114] The electrical installation box fixing member 60 is formed in a substantially L - shape and has 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 installation box support member 22.

[0115] The leaf spring portion 61 is formed by bending a metal plate, and is configured as a spring using the elasticity of the metal plate. The leaf spring portion 61 is an example of the spring portion.

[0116] The leaf spring portion 61 has a first peak portion 64 bent upward from a fixing portion 63A mounted on the rear flange portion 25, a second peak portion 65 bent downward, and a third peak portion 66 bent upward.

[0117] The first peak portion 64, the second peak portion 65, and the third peak portion 66 are configured with a gentle bending angle in this order.

[0118] The upper end of the rear wall 42 of the electrical installation box main body 21 at the time of storage abuts against the second peak portion 65. And when the electrical installation box main body 21 at the time of pulling out is pushed in for storage, the upper end of the rear wall 42 of the electrical installation box main body 21 is guided by the second peak portion 65 by means of a guiding surface portion 66A extending upward and forward from the third peak portion 66.

[0119] In this way, the electrical installation box main body 21 configured to be able to be pulled out in the forward direction is caught by the electrical installation box fixing member 60 having an anti-elasticity and mounted on the rear flange portion 25 of the electrical installation box support member 22 at the time of storage, and is pressed by the electrical installation box fixing member 60.

[0120] Thereby, the storage state of the electrical installation box main body 21 can be maintained without using fixing members such as screws and bolts. Furthermore, the number of components constituting the electrical installation box 20 and the assembly man-hours of the electrical installation box 20 can be reduced.

[0121] [1-1-5. Structure of the front cover and front wall of the electrical installation box main body]

[0122] Figure 8 is an exploded perspective view of the electrical installation box main body 21 and the front cover member 45.

[0123] The electrical installation box main body 21 has a front cover member 45 at a position in front of the front wall 43.

[0124] The front cover member 45 has front cover fixing members 70 on the left and right, and is configured to be detachable from the electrical installation box main body 21. A pair of left and right side walls 41 have side wall flange portions 74 bent inward at the front ends.

[0125] The front cover fixing member 70 is a resin rivet composed of a head 71 and a leg 72. The leg 72 is inserted through a through hole 73 of the front cover member 45 and a through hole 75 of the side wall flange portion 74, and the head 71 is inserted through the leg 72, whereby the front cover member 45 is fixed to the side wall 41.

[0126] The front cover member 45 has an upper cover portion 76 at the upper end. The upper cover portion 76 is formed by bending backward from the upper end of the front cover member 45 and then bending 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 installation box main body 21 is received.

[0127] Next, the front wall 43 will be described in detail. As Figure 4 and Figure 8 shown, the front wall 43 is provided at the front end of the bottom plate 44. The bottom plate 44 integrally formed 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.

[0128] As Figure 4 shown, the front wall 43 has front wall flange portions 77 at the left and right ends respectively. The left and right front wall flange portions 77 are respectively fixed to the left and right side walls 41 by fixing members 78. In addition, in Figure 4 only the left front wall flange portion 77 and the fixing member 78 are shown, but the right side has the same structure.

[0129] The lower end of the front wall 43 is bent backward and is configured 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.

[0130] As Figure 4 shown, a first sealing member 79 is pasted on the lower part of the inner surface of the front cover member 45. As Figure 4 and Figure 8 shown, a second sealing member 80 is pasted on the lower part of the outer surface of the front wall 43.

[0131] The first sealing member 79 and the second sealing member 80 are made of synthetic sponge, but are not limited thereto, as long as they are soft and elastic members. For example, they can also be cushioning materials or gaskets. The first sealing member 79 and the second sealing member 80 are examples of the "sealing member".

[0132] The first sealing member 79 is configured to be offset upward from the second sealing member 80. In the state where the front cover member 45 is installed, as Figure 4 shown, the first sealing member 79 and the second sealing member 80 are arranged in a mutually abutting manner to 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.

[0133] The front cover member 45 forms a handle 82 at a position below the first sealing member 79.

[0134] [1-1-6. Electrical installation components of the electrical installation box]

[0135] Figure 9 is a perspective view of the electrical installation box main body 21 as viewed from the left.Figure 10 It is an enlarged side view of the rear part of the electrical installation box main body 21. Figure 11 It is a top view of the electrical installation box main body 21. In Figure 11 it, the wiring 130 and the power supply wiring 131 omitted in other figures are illustrated. In addition, in Figure 11 it, the state where the front cover member 45 is disassembled is illustrated.

[0136] The electrical installation box main body 21 internally includes 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 installation components of the electrical installation box 20.

[0137] The first substrate 90 is arranged behind the terminal block 93 and to the left of the electrical installation box main body 21. The first substrate 90 is a substrate mainly related to power supply.

[0138] The second substrate 91 is arranged 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 a substrate mainly related to the communication with the storage chamber 1. The second substrate wiring in the wiring 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, the relay section 92, or other electrical installation components.

[0139] The second substrate 91 is provided with a communication connection portion 123 for connecting to a communication component. The communication connection portion 123 is arranged at the front end of the second substrate 91. The connection work for connecting the communication component to the communication connection portion 123 is carried out at the site of the storage chamber 1. Since the communication connection portion 123 is arranged on the pulling-out direction side of the electrical installation box main body 21, by only pulling out one end side in the pulling-out direction of the electrical installation box main body 21, the communication connection portion 123 of the electrical installation box main body 21 is exposed, and it is not necessary to remove the cover, and the factory inspection of the electrical installation box 20 and the connection work of the on-site construction can be easily carried out.

[0140] The second substrate 91 is provided with an antenna, a wireless communication circuit, etc. as a communication section, and communicates with each part of the storage chamber 1 or a device outside the storage chamber 1 according to the control of the control device provided in the storage chamber 1. Examples of the communication component connected to the communication connection portion 123 during on-site construction include a flexible flat cable. In addition, the communication component only needs to be a component corresponding to the specifications of the second substrate 91 and the communication connection portion 123, and can be appropriately changed.

[0141] The relay section 92 is configured to be able to connect a plurality of terminals. The relay section 92 is arranged at two corner portions on the rear side of the electrical installation box main body 21. In addition, the relay section 92 can be arranged at either of the two corner portions at the rear, or may not be arranged.

[0142] As Figure 10 shown, the relay unit 92 is a component in the shape of a substantially rectangular parallelepiped, and has claw portions 94 at the upper and lower parts respectively. The claw portions 94 are formed to gradually taper towards the ends, and have notch holes 95 formed by cutting from the ends towards the inside of the relay unit 92. The claw portion 94 at the upper part fixes the fixing member 96 to the side wall 41 by passing through the notch hole 95.

[0143] The claw portion 94 at the lower part is inserted into the insertion hole 97 formed at the corner of the side wall 41 and the bottom plate 44. As Figure 5 and Figure 10 shown, the insertion hole 97 is configured as a long hole-shaped through hole, and two are formed corresponding to the two end portions 94A of the claw portion 94. The relay unit 92 is fixed to the inner surface of the side wall 41 by means of a fixing member 96 and the insertion hole 97. In addition, in order to illustrate the insertion hole 97, the relay unit 92 is omitted in Figure 5 .

[0144] In this way, the relay unit 92 provided inside the electrical installation box main body 21 has claw portions 94 protruding downward, and the claw portions 94 are inserted into the insertion holes 97 formed in the electrical installation box main body 21. Thereby, it is possible to reduce fixing members such as screws and bolts for fixing the relay unit 92 to the electrical installation box main body 21. Furthermore, it is possible to reduce the number of components constituting the electrical installation box 20 and the assembly man-hours of the electrical installation box 20.

[0145] On the side wall 41 on the left side of the electrical installation box main body 21, a wiring hole 98 is formed at a position in front of the relay unit 92. The wiring hole 98 allows the wiring 130 for connecting components outside the electrical installation box main body 21 to components inside the electrical installation box main body 21 such as the first substrate 90, the second substrate 91, the relay unit 92, and the terminal block 93 to penetrate and be inserted.

[0146] On the side wall 41 on the left side of the electrical installation box main body 21, a bundling band 99 is provided at a position in front of the wiring hole 98. And a wiring clip 100 is provided at the front part of the side wall 41 on the left side of the electrical installation box main body 21.

[0147] In addition, the wiring clip 100 may also be provided on the bottom surface 44 of the electrical installation box main body 21.

[0149] As Figure 4 , Figure 8 and Figure 11 shown, a terminal block support member 110 is provided at the upper left of the front wall 43. In the cross-sectional view of Figure 4 , the part passing through the terminal block 93 is shown.

[0150] The terminal block 93 and the terminal block support member 110 are arranged on the front side of the electrical installation box main body 21. The front side in the present embodiment is an example of one end side in the pulling-out direction of the electrical installation box main body 21.

[0151] The terminal block support member 110 has a locking hole 118 at a corner portion on the upper surface closer to the second substrate 91 side. As Figure 11 shown, a bundling band 117 with a band locking portion for bundling a part of the second substrate wiring is inserted through the locking hole 118.

[0152] As Figure 4 shown, the terminal block support member 110 has a through hole 112 on the upper surface that fits with a locking portion 111 formed at the lower part of the terminal block 93. In addition, the upper surface of the terminal block support member 110 is formed to extend in a substantially horizontal direction, but is not limited thereto. For example, it may also be inclined so as to stand upright backward.

[0153] The terminal block support member 110 is fixed by two fixing members 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 fixing members 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 fixing member 116.

[0154] As Figure 4 and Figure 8 shown, the terminal block support member 110 has a foot plate portion 115 formed to bend downward on the right side, and the lower end of the foot plate portion 115 abuts against the bottom plate 44. Thereby, even when a strong stress is applied downward to the terminal block 93, deformation of the terminal block support member 110 can be suppressed. In addition, in Figure 4 it, the foot plate portion 115 is shown by a dotted line.

[0155] With the aid of the terminal block support member 110, the terminal block 93 is arranged on the upper side inside the electrical installation box main body 21, that is, on the side close to the upper end of the electrical installation box main body 21. And, with the aid of the terminal block support member 110 mounted on the front wall 43, the terminal block 93 is arranged on the front side inside the electrical installation box main body 21.

[0156] The terminal block 93 is configured as a quick-connect type terminal block. In a quick-connect type terminal block, different from a screw type terminal block, tools such as a screwdriver are not required, so wiring connection is easy. In addition, the terminal block 93 may be a screw type terminal block or a connection type terminal block.

[0157] The terminal block 93 has a front side connection portion 120 and a rear side connection portion 121. The front side connection portion 120 and the rear side connection portion 121 are formed on the side portion of the terminal block 93.

[0158] The rear connection part 121 has holes through which terminals and metal wires can be inserted. The wiring 130 connected to the rear connection part 121 is provided during the manufacturing stage of the storage chamber 1. The wiring 130 connected to the rear connection part 121 is introduced 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 bundling tape 99.

[0159] The front connection part 120 has holes through which terminals and metal wires can be inserted. The power supply wiring 131 connected to the front connection part 120 is connected during the installation of the storage chamber 1. Since the power supply wiring 131 is configured as a single wire, it has less flexibility compared to so-called twisted wires. A part or all of the power supply wiring 131 connected to the front connection part 120 is configured as wiring for connecting to the power supply available at the installation location.

[0160] In addition, the terminal block 93 has an inspection hole 122 on its upper surface. The inspection hole 122 is mainly used as an insertion hole for the terminals of the electrical measuring device.

[0161] The power supply wiring 131 extending from the front connection part 120 of the terminal block 93 is arranged from between the first sealing member 79 and the second sealing member 80 to the outside of the electrical installation box main body 21 and is supported by the wiring clip 100. The terminal block 93 is arranged such that the front connection part 120 is on the side of the second opening 81.

[0162] [1-2. Function, etc.]

[0163] In particular, as Figure 3 shown, the terminal block 93 is arranged on the pulling-out direction side of the electrical installation box main body 21, that is, on the front side of the storage chamber 1. Assuming that the terminal block 93 is not arranged on the pulling-out direction side of the electrical installation box main body 21 but is arranged in the center or the depth side of the electrical installation box main body 21, when connecting the 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 installation box main body 21.

[0164] During the on-site construction of the storage chamber 1, the wiring operation of the power supply wiring 131 is particularly carried out. And when the storage chamber 1 leaves the factory, the storage chamber 1 is inspected by connecting the terminals of the electrical measuring device to the terminal block 93 of the electrical installation box main body 21. In the present embodiment, without pulling out the entire electrical installation box main body 21, but only pulling out the front part, the wiring of the power supply wiring 131, the inspection of the storage chamber 1, etc. can be carried out.

[0165] Further, the upper part of the electrical installation box main body 21 is open, and the front connection part 120 of the terminal block 93 is configured to be accessible from above the electrical installation box main body 21 when pulled out. Since the electrical installation box 20 is provided at the lower part of the storage 1, from the viewpoint of workability, it is preferable that the components arranged inside the electrical installation box 20 are arranged to be accessible from above the electrical installation box main body 21.

[0166] In particular, as Figure 4 and Figure 11 shown, the power supply wiring 131 connected to the terminal block 93 is arranged outside the electrical installation box main body 21 via the upper end of the front wall 43 and between the first sealing member 79 and the second sealing member 80. Assuming that the power supply wiring 131 is arranged in a direction other than the front from the front connection part 120 and is arranged via an opening formed in the side wall 41 of the electrical installation box main body 21, the only part that the power supply wiring 131 passes through until it is pulled out to the outside of the electrical installation box main body 21 is the opening of the side wall 41.

[0167] In this case, compared with the arrangement of the power supply wiring 131 in the present embodiment, a relatively large tension is applied to the position of the front connection part 120 in the power supply wiring 131. In the present embodiment, the load on the power supply wiring 131 at the position of the front connection part 120 can be suppressed.

[0168] As Figure 4 shown, by means of the first sealing member 79 and the second sealing member 80, while the power supply wiring 131 is pulled out to the outside of the electrical installation box main body 21, the dustproof property of the electrical installation box 20 can be improved.

[0169] As Figure 4 shown, the electrical installation box main body 21 is configured to be pulled out forward of the storage 1, and the terminal block 93 is arranged to be offset backward from the front surface of the storage 1 by an amount corresponding to the upper cover part 76 of the front cover member 45. More specifically, when the electrical installation box main body 21 is stored, the trailing edge of the upper cover part 76 overlaps the front wall 43 in the vertical direction. Thus, although on the front side of the storage 1, the excreted water generated in the display room 3 easily falls, since the terminal block 93 is arranged to be offset backward from the front end of the electrical installation box main body 21, the waterproof property of the terminal block 93 can be improved.

[0170] [1-3. Effects, etc.]

[0171] As described above, the storage chamber 1 of the present embodiment is a storage chamber 1 equipped with an electrical installation box 20. The electrical installation box 20 has an electrical installation box main body 21 that houses electrical installation components and can be pulled out. The storage chamber 1 is equipped with a power supply wiring 131 connected to a power supply. The electrical installation box main body 21 is open upward, and a terminal block 93 connected to the power supply wiring 131 is housed in the electrical installation box main body 21. The terminal block 93 is arranged on the pull-out direction side of the electrical installation box main body 21, that is, the front side of the storage chamber 1.

[0172] According to this structure, since the terminal block 93 is arranged on the pull-out direction side of the electrical installation box main body 21, by only pulling out one end side in the pull-out direction of the electrical installation box main body 21, the terminal block 93 of the electrical installation box main body 21 is exposed, and it is not necessary to remove the cover. Therefore, the factory inspection of the electrical installation box 20 and the connection work of on-site construction can be easily carried out.

[0173] Moreover, the electrical installation box main body 21 is provided with a detachable front cover member 45 (cover 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 installation box main body 21. A second opening 81 (opening) is formed between the front wall 43 and the front cover member 45, and a sealing member for blocking the second opening 81 is provided.

[0174] According to this structure, wiring can be pulled out from the electrical installation components housed in the electrical installation box main body 21 through the second opening 81, and the dust-proof property of the electrical installation box main body 21 can be improved by means of the sealing member.

[0175] In addition, a first sealing member 79 is provided on the front cover member 45, and a second sealing member 80 is provided on the front wall 43. The lower surface of the first sealing member 79 is located above the lower surface of the second sealing member 80.

[0176] According to this structure, the position below the first sealing member 79 of the front cover member 45 functions as a handle 82 when pulling out the electrical installation box main body 21, so that the electrical installation box main body 21 can be easily pulled out.

[0177] Furthermore, the electrical installation box main body 21 is provided with a terminal block support member 110 for supporting the terminal block 93. The terminal block support member 110 is arranged on the front wall 43, and the terminal block 93 is arranged on the upper surface of the terminal block support member 110.

[0178] According to this structure, since the terminal block 93 is arranged on the upper side inside the electrical installation box main body 21, the factory inspection of the electrical installation box 20 and the connection work of on-site construction can be further easily carried out.

[0179] Moreover, a wiring clip 100 (wiring support portion) is provided on the outer side surface of the electrical installation box main body 21. The power supply wiring 131 is connected to the second opening portion 81 side of the terminal block 93, pulled out from the terminal block 93 through the second opening portion 81 to the outside of the electrical installation box main body 21, and supported by the wiring clip 100.

[0180] According to this structure, the connection portion of the power supply wiring 131 connected to the terminal block 93 is located on the same side as the direction in which the power supply wiring 131 is pulled out to the outside of the electrical installation box main body 21. Moreover, even when tension is applied to the power supply wiring 131 pulled out from the terminal block 93, since the power supply wiring 131 abuts against the corner portions of the terminal block support member 110 and the front wall 43, the load applied to the connection portion of the power supply wiring 131 can be suppressed.

[0181] Moreover, the terminal block 93 is configured as a quick-connect type.

[0182] According to this structure, compared with the screw type, tools such as a screwdriver are not required, and thus, the connection work for factory inspection and on-site construction can be easily performed.

[0183] Moreover, the electrical installation box 20 is provided with an electrical installation box support member 22. The electrical installation box support member 22 has 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), and is provided with an electrical installation box fixing member 60 provided on the rear flange portion 25. The electrical installation box fixing member 60 has a leaf spring portion 61 (spring portion).

[0184] According to this structure, fixing members such as screws for maintaining the storage state of the electrical installation box main body 21 are not required, and thus, the assembly man-hours of the electrical installation box 20 can be reduced.

[0185] Moreover, a rail portion 28 extending in the pulling-out direction is formed on the electrical installation box support member 22, and a slideway portion 46 extending in the pulling-out direction is formed on the electrical installation box main body 21. The pulling-out mechanism 48 of the electrical installation box 20 is constituted by the rail portion 28 and the slideway portion 46. A notch portion 47 is formed at the central portion of the rail portion 28, and a protrusion portion 30 is formed at one end side in front of the slideway portion 46.

[0186] According to this structure, when the electrical installation box main body 21 is pulled out by a sufficient amount during the factory inspection and on-site construction of the terminal block 93, the protrusion portion 30 is caught by the notch portion 47, and thus, it is easy to bring the electrical installation box main body 21 into the state during pulling out.

[0187] Further, a relay unit 92 capable of connecting a plurality of terminals is housed in the electrical installation box body 21. The relay unit 92 includes two claw portions 94. One of the upper claw portions 94 is fixed to the electrical installation box body 21 by a relay unit fixing member 96 (fixing member), and the other lower claw portion 94 is inserted through an insertion hole 97 formed in the electrical installation box body 21.

[0188] According to this structure, the number of fixing members used for fixing the relay unit 92 can be reduced, and the assembly man-hours of the electrical installation box 20 can be reduced.

[0189] Further, the terminal block 93 is disposed at a position on the side opposite to the pulling-out direction with respect to the front wall 43 in the housing direction. The front cover member 45 includes an upper cover portion 76 formed to be bent toward the housing direction. When the electrical installation box body 21 is housed, the edge of the upper cover portion 76 is disposed at a position overlapping the front wall 43 in the vertical direction.

[0190] According to this structure, the terminal block 93 connected to the power supply wiring 131 is disposed on the front side of the storage 1 and the electrical installation box body 21, and is disposed offset backward from the front end of the electrical installation box body 21. Therefore, it is possible to prevent the drainage water from falling onto the terminal block 93.

[0191] Specifically, even when the drainage water falls through the gap between the upper cover portion 76 and the front flange portion 24, the drainage water easily falls forward of the front wall 43.

[0192] Further, a rail portion 28 is formed by bending the side edge of the electrical installation box support member 22 formed of a metal plate upward, and a slide portion 46 is formed by bending the side wall 41 of the electrical installation box body 21 inward.

[0193] According to this structure, since the rail portion 28 and the slide portion 46 are formed by bending and combined, it is difficult for drainage water and the like to penetrate, and thus the waterproof property of the electrical installation box 20 can be improved.

[0194] Further, the rail portion 28 has a protruding portion 33 at one end side. The protruding portion 33 is formed to extend in the pulling-out direction beyond one end of the slide portion 46. The protruding portion 33 has a wedge portion 31 formed to taper toward the pulling-out direction.

[0195] According to this structure, the visibility in front of the storage 1 of the protruding portion 33 is high, and by means of the protruding portion 33 and the wedge portion 31, it is easy to assemble the electrical installation box body 21 when it is being housed during removal, and it is possible to easily install the electrical installation box body 21 onto the electrical installation box support member 22.
