  In the assembly process of the outer box 10, first, a plurality of forming members are joined to form a main part 110 of the machine room M (hereinafter also referred to as a machine room main part, see FIG. 5) (first process). Here, the forming members are the base body 111, the outer box bottom plate 112, and various reinforcing bars 113. The base body 111 is a portion that becomes the base 11 of the outer box 10 and has a substantially flat plate shape. The left and right ends (side ends) of the base body 111 are each formed with a pair of downward extending portions 111a that extend slightly downward. The code | symbol 111b is a position which performs the spot welding mentioned later. The outer box bottom plate 112 is a portion that becomes the outer box bottom plate 112 of the outer box 10, that is, the bottom surface 12 that divides the storage chamber R and the machine room M, and has a substantially flat plate shape. The lateral width of the outer box bottom plate 112 is slightly smaller than the base body 111. On the peripheral edge of the outer box bottom plate 112, a bent portion 112a formed by slightly bending upward is formed. In addition, a notch 112b is formed between each bent portion 112a formed at the front edge portion and the rear edge portion of the outer box bottom plate 112 and a bent portion 112a formed at the side edge portion of the outer box bottom plate 112. It is formed. As the various reinforcing bars 113, there are a base reinforcing bar 113a and a plurality of machine room reinforcing bars 113b. The base reinforcing metal 113 a is disposed under the base main body 111 to reinforce the base main body 111. The plurality of machine room reinforcing bars 113b are for securing the volume of the indoor space of the machine room M. Therefore, the height dimension of each machine room reinforcing metal 113b is the same. The plurality of machine room reinforcing bars 113b are appropriately bent, and flanges (joining portions) 113b1 are formed on the upper side and the lower side. Reference numeral 113b2 is a position where spot welding described later is performed.

  In the first step, the plurality of machine room reinforcing bars 113b are respectively erected by being joined to predetermined positions on the upper surface of the base body 111. More specifically, each machine room reinforcing metal 113b is placed at a predetermined position in a state where the lower flange 113b1 of each machine room reinforcing metal 113b is in contact with the upper surface of the base body 111. Then, spot welding is performed by inserting a welding electrode (not shown) into the spot welding position 113b2 shown in FIG. As a result, as shown in FIG. 4, each machine room reinforcing metal 113b is erected as a result of being joined to a predetermined location on the upper surface of the base body 111 via the flange 113b1.

  Thereafter, the outer box bottom plate 112 is placed on the flange 113b1 above each machine room reinforcing metal 113b erected on the base body 111, and a welding electrode (not shown) is inserted into the spot welding position 113b2 shown in FIG. Then, spot welding is performed by passing an electric current. As a result, the outer box bottom plate 112 is joined to each machine room reinforcing metal 113b. And the machine room main part 110 is formed by joining the base reinforcement 113a to the lower part of the base main body 111, as shown in FIG.

The outer box main body 100 includes a main body portion 101 and a back plate 103. The main body portion 101 is formed by bending a single flat plate, and includes an upper surface portion 101a and a pair of side surface portions 101b extending downward from the left and right ends of the upper surface portion 101a. Here, the upper surface portion 101 a is a portion that forms the upper surface 13 of the outer box 10, and the pair of side surface portions 101 b are portions that form the pair of side surfaces 14 of the outer box 10. The upper surface 101 a of the main body 100 has a lateral width that is substantially equal to the base main body 111 and a front-rear width that is slightly smaller than the base main body 111. The back plate 103 extends downward from the rear end of the upper surface portion 101 a of the main body portion 100, and is a portion that forms the back surface 15 of the outer box 10, more specifically, the back surface 15 of the storage chamber R. Therefore, the downward extending distance of the back plate 103 is shorter than the extending distance of the side surface part 101 b of the main body part 100.

  The machine room main part 110 is inserted into the lower part of the outer box main body 100, and the lower extension part 111 a of the base main body 111 constituting the machine room main part 110 constitutes the outer box main body 100. The outer box 10 as shown in FIG. 2 is formed by joining to the lower end part of a pair of side part 101b of the main-body part 101. As shown in FIG. More specifically, after bringing the outer surface of each extending portion 111a of the base body 111 into contact with the inner surface of the lower end portion of the corresponding side surface portion 101b, the welding electrode is inserted into the spot welding position 111b shown in FIG. Spot welding is performed by passing an electric current. Thereby, the base main body 111 and the main-body part 101 (a pair of side part 101b) will join.

  Further, a side reinforcing metal 102 for disposing a heat insulating board is disposed on the inner surface of the side surface portion 101b of the outer box main body 100 (main body portion 101). As shown in FIG. 5, the side reinforcing metal 102 is disposed on the front inner surface of the pair of side surface parts 101 b in a manner extending in the vertical direction. Then, as shown in FIG. 6, the end of the side reinforcing metal 102 enters the notch 112 b of the outer box bottom plate 112 to engage the side surface 101 b in a state where the outer box bottom plate 112 is positioned. become.
