[0010]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1, FIG. 2 (A) and FIG. 2 (B)
In 1 and 2, 1 is a bottom plate on which a compressor (not shown), a heat exchanger (not shown), etc. are mounted, and a plurality of mounting screw holes 1a are provided in a flange that is erected on four sides.

Reference numeral 2 is a front cover which constitutes a part of both side surfaces and an upper surface and a front surface, and 3 is a rear cover which constitutes a part of the upper surface and a back surface and both side surfaces, and which are provided relative to the front cover 2 and the rear cover 3. Facing male-female junction
2a and 3a are joined, and mounting holes 2b and 3b are provided on the front cover 2 and the rear cover 3 so as to face the mounting screw holes 1a provided on the flanges on the front and rear of the bottom plate 1, and the mounting holes 2b and 3b are formed. With the bottom plate 1 and the cover made of synthetic resin, which is composed of the front cover 2 and the rear cover 3, which is screwed into the mounting screw hole 1a by the inserted mounting screw 5a and attached to the flange of the bottom plate 1, The outdoor unit body of the air conditioner is configured. An electric component cover 4 for covering the electric component is attached to one side surface of the rear cover 3.

The mounting screw hole 1a and the mounting hole 3b are provided between the flange and the rear cover 3 facing the mounting screw holes 1a provided on the flanges on both sides of the bottom plate 1.
The front cover 2 is provided with a through hole 2e corresponding thereto, and the projecting portions 2d projecting from both side surfaces of the front cover 2 are interposed, and the mounting screw 5a is inserted through the mounting hole 3b and the through hole 2e. The cover is attached to the flange of the bottom plate 1 by being screwed to 1a and by tightening the front cover 2 and the rear cover 3 together. The joints 2a and 3a can be corrected by the distortion (warpage) so as not to be separated from each other, and the appearance can be prevented from being spoiled, and the front cover 2 and the rear cover 3 can be individually attached to the bottom plate 1. Compared with the work of attaching to the flange, the work is easier.

The front cover 2 and the rear cover 3 are provided on the rear cover 3 by joining the joining portions 2a and 3a and a set screw 5b inserted through an insertion hole 2c formed in the front cover 2. It is fixed by being screwed into the set screw hole 3c.

Further, the projecting portion 2d is formed integrally with the front cover 2, so that the dimension and shape can be accurately finished and the cost is advantageous.

Further, the through hole 2e is replaced with the mounting screw hole 1a.
The side is formed with a dish-shaped hole with a small diameter, while the mounting screw
5a uses a so-called screw with a seat so that the joint portions 2a and 3a are not separated from each other due to the distortion (warpage) of the front cover 2 generated during molding.
It has a structure that can be corrected more effectively.

With the above structure, as shown in FIG. 1 and FIGS. 2 (A) and 2 (B), the synthetic resin covers 2 and 3 attached to the bottom plate 1 are connected to the joint portion. It can be corrected so that 2a and 3a are not separated from each other, and it can be prevented that the appearance is not impaired.
3b and the through hole 2e through the mounting screw 5a can be tightened together with the mounting screw hole 1a, as compared with the cover 2 and 3 are individually attached to the flange of the bottom plate 1, It becomes an outdoor unit of an air conditioner that allows easy work.

[0017]

As described above, according to the present invention, there is provided an outdoor unit for an air conditioner in which a synthetic resin cover to be attached to a bottom plate can be easily and accurately attached.
