DESCRIPTION OF THE PREFERRED EMBODIMENTS With the above construction, a connecting valve portion for connecting a connecting pipe of a synthetic resin top cover is reinforced with a reinforcing metal fitting, so that a person or an object can be put on the pipe work or the like. In this case, the outdoor unit is an air conditioner having a structure capable of preventing deformation and breakage of the top cover.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1, FIG. 2, FIG. 3 (A) and FIG.
In (B), the outdoor unit main body is composed of a base 1, a synthetic resin front panel 2 serving as a decorative cover, a rear cover 3 and a top cover 4, and is mounted substantially at the center on the front side of the base 1. The compressor 5, a heat exchanger 6 that is provided over the rear side and both side surfaces of the compressor 5, and is formed to be bent substantially in a concave shape, and is provided to face the rear side of the heat exchanger 6. A blower 7, a metal electrical component box 8 fixed to the upper ends of side plates 6 a provided on both sides of the heat exchanger and containing electrical components, and one side of the electrical component box 8 (not shown) Terminal board for connecting cables and two-way valve 9a for connecting connection piping
And a connection valve comprising a three-way valve 9b and the like, and a valve fitting 9 for mounting the connection valve.

A reinforcing member 10 is provided inside the upper cover 4 facing the valve mounting member 9, a plurality of ribs 4 a are protruded inside the upper cover 4, and the reinforcing member 10 is screwed to the rib 4 a with a screw 11. Fix it. When the upper cover 4 is attached to the main body, one side of the reinforcing metal fitting 10 is locked at the upper end of one side of the electrical component box 8 and the other side is held at the upper end of the side plate of the heat exchanger 6. The cover 9 is configured to be reinforced. Further, the reinforcing metal fitting 10 is provided on the upper surface and one side surface of the upper surface cover 4 so as to be substantially L-shaped.

In the above configuration, the upper cover 4 made of synthetic resin is reinforced by the electrical component box 8 against the force from above, and the connection valve portion connecting the connection pipe is reinforced by the reinforcing metal fitting 10. Accordingly, when a person or an object is put on the pipe work or the like, an outdoor unit of an air conditioner having a structure capable of preventing the upper cover 4 from being deformed or damaged.
