DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, specific embodiments of the outdoor unit of the air conditioner of the present invention will be described in detail with reference to the drawings.

FIG. 2 is a side view of a bottom frame constituting a main body casing of the outdoor unit. This bottom frame is
The bottom plate 2 constituting the bottom side of the main body casing and the closing valve mounting plate 1 erected on the short side of the bottom plate 2 are integrally formed by a single member. That is, the upright edge portion 7 formed upright on the peripheral edge of the bottom plate 2 is directly extended upward at the center of the short side of the bottom plate 2 to form the closing valve mounting plate 1.

FIG. 1 (a) is a front view of the closing valve mounting plate 1, and FIG. 1 (b) is a sectional view taken along the line AA. As shown in these figures, the closing valve mounting plate 1 is short in the vertical direction and long in the horizontal direction. A valve mounting portion 8 formed at the center thereof so as to protrude outward from the outdoor unit.
Is provided. With this projection, the connecting portion 9 that connects the valve mounting portion 8 and the closing valve mounting plate 1 obliquely to the plate surface of the closing valve mounting plate 1 surrounds the periphery of the valve mounting portion 8. Is formed.

The valve mounting portion 8 is provided with a first mounting hole 5 for mounting a gas shut-off valve and a second mounting hole 6 for mounting a liquid shut-off valve. Further, screw holes 10 for fixing a closing valve are provided on both oblique sides of the mounting holes 5 and 6, respectively. On both sides of the valve mounting portion 8, the upright edge portion 7 is provided.
Ribs 3 and 4 extending in the vertical direction from the lower end of the valve to the top of the closing valve mounting plate 1 are provided. These ribs 3, 4
The first rib 3, which has a substantially semicircular cross section so as to be depressed toward the inside of the outdoor unit, is provided on the first mounting hole 5 side,
It is formed thicker than the second rib 4 provided on the second mounting hole 6 side. In addition, the closing valve mounting plate 1 is provided with a notch portion 13 which cuts off an upper corner portion on the second mounting hole 6 side diagonally. Along the notch 13, the connecting portion 9 is also formed with an inclined portion 14 which extends obliquely.

FIG. 3 is a perspective view showing the assembly of the bottom frame constituted by the above-described closing valve mounting plate 1 and bottom plate 2 and the side plate 11 mounted on the bottom frame. The side plate 11 is attached so as to cover a compressor and the like installed in the outdoor unit from the side and the back side, and forms a main body casing. A cutout 12 which is substantially the same shape as the outer shape of the valve mounting portion 8 and is slightly larger than the cutout 12 is provided at a lower portion of the side surface of the side plate 11.
Then, the side plate 11 is attached to the bottom frame such that the notch 12 overlaps the closing valve attachment plate 1. Then, since the notch 12 is slightly larger than the valve mounting portion 8, the outer peripheral surface of the closing valve mounting plate 1 is
2, the valve mounting portion 8 is exposed from the notch 12 to the side.

In the outdoor unit of the air conditioner, the closing valve mounting plate 1 and the bottom plate 2 are integrally formed by a single member. Therefore, the connecting step such as the conventional spot welding is not required, and the number of assembling steps of the outdoor unit can be reduced and the cost can be reduced. Further, since the ribs 3 and 4 extending in the vertical direction are provided on both sides of the valve mounting portion 8, even if the thickness of the closing valve mounting plate 1 is not particularly larger than the thickness of the bottom plate 2, the closing valve mounting plate 1 is not required. And the closing valve can be reliably supported. In addition, since the ribs 3 and 4 have a semicircular cross section, sufficient strength can be exhibited against vertical bending applied to the closing valve mounting plate 1. Further, in the above, the closing valves are arranged side by side in the horizontal direction. Therefore, with the lower base end of the closing valve mounting plate 1 as a fulcrum, the moment applied to the closing valve mounting plate 1 in a vertical plane by operating the closing valve is smaller than in the related art in which the closing valves are vertically arranged. Further, the strength against the above moment is also ensured by making the closing valve mounting plate 1 longer in the horizontal direction than in the vertical direction. Therefore, the support of the closing valve is more reliable.

The shutoff valve is somewhat larger in the gas shutoff valve than in the liquid shutoff valve, corresponding to the thickness of the refrigerant pipe.
Therefore, the ribs 3 and 4 are made thicker on the side where the gas shutoff valve is mounted than on the side where the liquid shutoff valve is mounted. Therefore, the strength of the closing valve mounting plate 1 on the side where the large gas closing valve is mounted is further enhanced. The outer peripheral portion of the closing valve mounting plate 1 is provided with a notch 1 provided in the side plate 11.
2 supported from the outside by the periphery. Therefore, even if an outward pulling force is applied to the closing valve mounting plate 1, the side plate 11 can prevent the closing valve mounting plate 1 from being deformed.
In addition, a notch 13 is provided in the closing valve mounting plate 1 so that the side plate 11 supports the very close vicinity of the mounted liquid closing valve. Therefore, deformation of the closing valve mounting plate 1 is more reliably prevented. Furthermore, since the valve mounting portion 8 is formed so as to protrude from the plate surface of the closing valve mounting plate 1, the strength of the closing valve mounting plate 1 is also increased, and the closing valve can be more reliably supported.

Although the specific embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and can be implemented with various modifications within the scope of the present invention. For example, the illustrated closing valve mounting plate 1 and ribs 3,
The shape of 4 is an example, and can be variously changed within a range that the closing valve can surely support. Although the closing valve mounting plate 1 is provided on the side of the bottom plate 2 in the above description, a change such as providing the closing valve mounting plate 1 on the back side or the front side of the bottom plate 2 is also possible.

【The invention's effect】

In the outdoor unit of the air conditioner according to the first aspect,
By forming the bottom plate and the closing valve mounting plate as a single member as a single member, the step of connecting both members can be omitted. Therefore, the cost of the outdoor unit can be reduced by reducing the number of man-hours.

In the outdoor unit of the air conditioner according to the second aspect,
By providing the ribs, the strength of the closing valve mounting plate can be sufficient to support the closing valve. Therefore, even if the closing valve mounting plate has the same thickness as the bottom plate, the closing valve can be reliably supported.

Further, in the outdoor unit of the air conditioner according to the third aspect, the moment generated by the mounted closing valve and applied to the closing valve mounting plate can be reduced. Therefore, even if the closing valve mounting plate has the same thickness as the bottom plate, the closing valve can be reliably supported.
