Embodiments of the present invention will be described in detail below with reference to the drawings. As shown in the schematic cross-sectional view of FIG. 1, the outdoor unit of the air conditioner has an outer shell made up of a base 1, an outer case 2, and a top plate 3, and an interior made by a partition plate 4 into a heat exchange chamber 5.
A heat exchanger 7 and a blower 8 in the heat exchange chamber 5, and a compressor 9 on the base 1 in the machine chamber 6.
And the electrical component box 10 is disposed on the upper part of the box. An opening 11 is formed on one side of the outer case 2 of the outer case 2 facing the machine room 6, and a detachable electric equipment cover 12 is attached to the opening 11. The bottom plate 13 of the electric component box 10 extends forward and backward, one end of the bottom plate 13 is screwed to the partition plate 4, and the other end is screwed to the lower end of the opening 11. Rather, the cable is connected to the outside.

The mounting structure of the bottom plate 13 of the electric component box 10 will be described. As shown in FIG. 2, a flange 4a, which is a supporting piece bent to the opening 11 side by cutting and bending, is formed in the center of the partition plate 4, and screw holes 4b are formed on both sides of the flange 4a. Has been drilled. Further, a flange 2a that is bent inward is formed at the lower end of the opening portion 11 of the outer body 2, and slit-shaped locking holes 2b are formed at both roots of the flange 2a and the opening portion is formed. A screw insertion hole 2c is formed below 11 so as to correspond to the locking hole 2b. The bottom plate 13 is formed with a through hole 13c at one end corresponding to the screw hole 4b of the flange 4a of the partition plate 4, and the other is formed in a step shape, and the opening is formed on both sides of the step. A downwardly extending locking piece 13a corresponding to the locking hole 2b of the flange of the portion 11 is formed, and the locking piece 13a is provided with a screw hole 13b. The electrical equipment cover 12 has a recess formed on the surface as a handle, and L-shaped locking claws 12a project from both sides of the upper end of the electrical cover 12, and the screw insertion hole 2c of the outer case 2 is provided at the lower end. A through hole 12b corresponding to is formed. A rib 12c is erected laterally on the rear surface above the through hole 12b.

With the above configuration, the electrical component box 10 for the outdoor unit
The assembling procedure will be described. Flange 4 of the partition plate
One of the bottom plates 13 is placed on a and the other locking piece 13a is inserted into the slit-shaped locking hole 2b of the opening flange 2a. The screw insertion hole 13c
The screw 14 is inserted into the screw hole and screwed into the screw hole 4b of the flange 4a to fix one of the bottom plates 13. The locking claws 12 a of the electrical component cover 12 are attached to the opening 11 so as to lock the upper ends of the opening 11. At this time, the electrical equipment cover 12
The rib 12c formed on the back surface is positioned so as to press the stepped portion of the holding plate 13 from above, and serves to prevent the bottom plate locking piece 13a from coming off. Through hole 12 of the electrical equipment cover
The electrical component cover 12 and the bottom plate 13 are fixed by the same screw by inserting a screw 14 into the screw insertion hole 2c of the outer case 2 and screwing the screw 14 into the screw hole 13b of the locking piece 13a.

As a result, a screw for fixing the bottom plate to the lower end of the opening by screwing and a screw for fixing the electrical component cover on the opening by screwing are commonly used.

As another embodiment, as shown in FIG. 4, a slit-shaped locking hole is formed in the flange of the partition plate, and an L-shaped locking piece which is locked in the locking hole at one end of the bottom plate. There is also a structure in which the number of fastening parts is reduced by providing the. There is also a method in which the flanges of the partition plate are provided above and below and one end of the holding plate is held between the flanges.
