After being bent, it is inserted into the folded portion 29 of the top panel 25 beyond the rear wall 29D.

As shown in FIG. 2, a cooler box 40 is installed above the machine room 20. A box panel 41 is provided on the front surface of the cooler box 40. The box panel 41 is a resin member constituting the front surface of the cooling chamber, and is integrally molded with the main body 12 by foaming a foaming agent in the main body 12. As shown in FIG. 14, the upper surface of the box panel 41 is arranged so as to be flush with the upper surface 17A of the front frame 17, and the box panel 41 is substantially in contact with the side surface 17B of the front frame 17. Further, the lower surface of the box panel 41 is arranged so as to be flush with the lower surface of the cooler box 40.

As shown in FIG. 6, the upper end portion of the box panel 41 is provided with a reinforcing portion 42 having a form of projecting forward. As shown in FIG. 2, the reinforcing portion 42 is covered from the front by the front wall 29B of the top panel 25. A fastening portion 43 is provided near the center of the reinforcing portion 42, and the fastening portion 43 is a hole for screwing the front panel 23. Further, as shown in FIG. 8, a mounting hole 51 is provided at the upper left of the fastening portion 43 in the front view. A fourth opening 31 is provided at a position corresponding to the mounting hole 51 on the front wall 29B of the top panel 25. The top panel 25 and the box panel 41 are integrally fixed by inserting the screw 19 through the fourth opening 31 and fastening the screw 19 to the mounting hole 51 through the insertion hole provided in the rear wall 29D of the top panel 25. There is. By supporting the top plate 15 from below via the top panel 25, the reinforcing portion 42 prevents the top plate 15 from being deformed even when a load is applied by a person placing a hand on the front end of the top plate 15. ..

The main body 12 side of the reinforcing portion 42 is provided with a vertical through hole 44 that penetrates in the vertical direction and opens forward. The rear surface of the upper and lower through holes 44 has a semicircular shape in a plan view. A concave groove 45 is provided near the center of the box panel 41 in the vertical direction. As shown in FIG. 18, the concave groove 45 has a form extending in the horizontal direction. A pair of temporary holding pieces 46 are provided on both the left and right sides of the concave groove 45. Further, a front-rear through hole 47 penetrating in the front-rear direction is provided at the end of the concave groove 45 on the main body 12 side. An AC wiring 48 different from the DC wiring 18 is inserted through the concave groove 45. The AC wiring 48 is accommodated by closing the concave groove 45 with the rear surface of the electrical box 22. The concave groove 45 may be formed diagonally as shown by the alternate long and short dash line in FIG.

The AC wiring 48 is wiring used for a temperature sensor or the like, and enters the concave groove 45 from the right through the front-rear through hole 47 from the rear of the box panel 41, and enters the concave groove 45 from the right by the temporary holding piece 46 from the front surface to the front of the box panel 41. It is guided to the left end of the box panel 41 in a non-protruding manner, and is connected to the electrical box 22 so as to wrap around from below.

As shown in FIG. 18, the DC wiring 18 faces left in the folded portion 29 of the top panel 25, faces rearward at the position of the first opening 26, and faces downward through the upper and lower through holes 44, and is an electrical box. It passes between the side surface of the 22 and the side surface of the main body 12, faces downward, and is connected to the electrical box 22 so as to wrap around from below.

Although the DC wiring 18 and the AC wiring 48 intersect at the positions of the front and rear through holes 47, the DC wiring 18 is located in front of the AC wiring 48, so that they do not come into contact with each other. Therefore, it is possible to prevent the DC wiring 18 and the AC wiring 48 from coming into contact with each other to generate noise, which affects communication and leads to poor control.

A box receiving portion 49 is provided below the fastening portion 43 in the box panel 41. As shown in FIG. 12, the box receiving portion 49 supports the upper end portion of the electrical box 22. An L-shaped bracket 22A is attached to the lower end of the electrical box 22, and the rear surface of the bracket 22A projects rearward from the rear surface of the electrical box 22. On the other hand, at the lower end of the box panel 41, a fastening portion 50 for fastening the bracket 22A of the electrical box 22 is provided. When the rear surface of the bracket 22A is fixed to the fastening portion 50 with screws, the electrical box 22 is fixed to the box panel 41 with a predetermined gap as shown in FIGS. 12 and 13.

By the way, in this embodiment, the wiring work of the DC wiring 18 can be performed from the front of the main body 12. As shown in FIG. 1, the DC electric wire 18 is once pulled upward from the inside of the storage chamber 11 through the upper surface opening of the wiring insertion member 30, then bent forward and inserted into the folded portion 29 from the second opening 27. When the DC wiring 18 coming out of the folded-back portion 29 is once pulled upward through the first opening 27 and then inserted into the upper and lower through holes 44, the DC wiring 18 passes between the electrical box 22 and the side surface of the main body 12. It is guided downward and connected to the electrical box 22. As described above, when the DC wiring 18 is pulled out from the folded-back portion 29, it is not necessary to wrap around the side surface of the main body 12, and the wiring work can be performed from the front surface of the main body 12.

Further, the first opening 27 and the second opening 28 are originally work holes for screwing the screw 19, but also serve as a notch for wiring work. Therefore, a tool such as a screwdriver is inserted from the first opening 27 and the second opening 28, the rear wall 29D of the top panel 25 is screwed to the front frame 17 of the main body 12 with screws 19, and the top panel 25 is fixed to the main body 12. can do. The third opening 28 is not used as a notch for wiring work, but is used as a work hole for screwing the rear wall 29D of the top panel 25 to the front frame 17 of the main body 12 with screws 19.

As described above, in the present embodiment, the wiring (DC wiring 18) in the folded-back portion 29 can be routed between the electrical box 22 and the side surface of the main body 12 by inserting the wiring (DC wiring 18) into the upper and lower through holes 44 from above. Therefore, the wiring work can be performed from the front of the main body 12. In addition, since the dedicated work hole for screwing work has been abolished and an opening (first opening 26) for screwing work and wiring work has been provided, the man-hours for processing sheet metal for manufacturing the top panel 25 can be reduced. Can be done.

Further, the vertical through hole 44 may be a hole that penetrates in the vertical direction and opens forward, and may be closed from the front by the folded-back portion 29.
According to such a configuration, when the top panel 25 is assembled to the main body 12, the upper and lower through holes 44 are formed in the box panel 41, so that the upper and lower through holes 44 can be easily formed.

The box panel 41 is integrally molded with the main body 12, and a reinforcing portion 42 covered with the top panel 25 is provided so as to project forward at the upper part of the box panel 41, and the upper and lower through holes 44 are provided in the reinforcing portion 42. It may be configured as such.
According to such a configuration, since the front end portion of the top panel 25 is reinforced by the reinforcing portion 42, a person puts a hand on the front end portion of the top plate 15 and a load is applied to the front end portion of the top panel 25. In this case, it is possible to prevent the top plate 15 from being deformed. In particular, since the box panel 41 is integrally molded with the main body 12, the structure is such that the entire box panel 41 and the main body 12 receive a load, and the top plate 15 can be prevented from being deformed by a large load.
The opening for mounting work may be configured to be an opening for screwing work (first opening 26) in which the rear wall is screwed to the front frame.
According to such a configuration, the rear wall 29D of the top panel 25 can be screwed to the front frame 17 of the main body 12 by inserting a tool through the opening for screwing work.
