And an electrical cover 23 made of synthetic resin that covers the opening 22a, and protects an outdoor heat exchanger (not shown), a blower, a compressor, etc., which are arranged on the base 24. there were.

[0003]

However, since the outdoor unit is installed outdoors, it is exposed to the weather.
Scales adhere to the outer body not only on the upper surface (top plate) but also on the front and side surfaces, and the stains are promoted to make the outer body more conspicuous. Therefore, an object of the present invention is to provide an outdoor unit of an air conditioner that can reduce adhesion of scale and the like to at least the front surface and both side surfaces of the outer trunk and does not impair the appearance.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and the inside of a main body comprising a base and an outer trunk is partitioned into a heat exchange chamber and a machine room by a partition plate.
An outdoor heat exchanger is provided in the heat exchange chamber, and a blower fixed to a motor mounting plate erected on the base and discharging air exchanged by the outdoor heat exchanger to the outside is provided. A compressor is disposed at the lower part of the upper part, and an electric component box containing electric components for control is provided at the upper part, and a bank is provided at the upper end of the front end and both left and right ends of the top plate constituting the outer shell. The upper surface is provided with a slope lowering the central portion, and a water passage hole is formed in the central portion of the upper surface of the top plate, while the upper end portion of the motor mounting plate extends toward the front cover of the outer body, From the upper surface to the lower rear portion, a water channel for guiding water flowing down from the water hole to the base is provided.

It is to be noted that the water channel is formed to have a concave cross section.

In addition, the motor mounting plate having the water channel has a structure in which the front of the upper surface is raised and the upper surface is inclined.

The water passages are provided in parallel from the upper left and right sides of the upper surface of the motor mounting plate to the rear lower portion, and water holes corresponding to the two water passages are provided at the center of the top plate.

Further, a drain hole is provided in a base near the lower part of the water channel.

[0009] Further, the motor mounting plate has a structure in which an upper front portion is fixed to the front cover.

FIG. 1 is a block diagram showing an embodiment of the present invention.
This will be described with reference to FIG. FIG. 1 shows a schematic configuration of an outdoor unit of an air conditioner. The main body of the outdoor unit includes a base 1 made of a steel plate and an outer body, and the outer body has a front cover 2 having an outlet 2a. A rear cover 3 having a suction opening (not shown) on the left and right sides and a right side having an opening 3b for electrical equipment; and an electrical cover for covering the opening 3b. 4 and a top plate 5 to be attached to the upper portion, and these are made of synthetic resin.

The interior of the main body is partitioned by a partition plate 6 into a left heat exchange chamber 7 and a right machine chamber 8. The heat exchange chamber 7 has an L-shaped outdoor heat exchanger 9, An air blower 11 fixed to a motor mounting plate 10 erected at the outside and discharging the heat exchanged by the outdoor heat exchanger 9 to the outside is arranged. An electrical component box 14 (both made of a steel plate) is provided at an upper part thereof, and accommodates electrical components for control and the like and covers the lid 13.

In the present invention, a bank 5a is provided on the front end and upper portions of the left and right ends of the top plate 5, and a slope is provided on the upper surface so as to lower the center portion. While forming the water passage hole 5b, the upper end of the motor mounting plate 10 is extended toward the front cover 2,
From the upper surface to the lower rear, the water holes 5 of the top plate 5
It is characterized in that a water passage 10a having a concave cross section for guiding water (rainwater or the like) flowing down from b to the base 1 is provided.

The water passage 10a is provided in parallel on the left and right from the upper surface of the motor mounting plate 10 to the lower rear thereof, and the upper front of the motor mounting plate 10 is screwed to the front cover 2, and the upper front thereof is fixed. As shown in FIG. 2, the upper surface (the water passage 10a) is slightly inclined and the upper surface (the water passage 10a) is inclined to improve the flow of water. In addition, a drain hole 1a is provided in the base 1 near the lower part of the water channel 10a, so that the water flowing down can be quickly drained. FIG. 3 is a cross-sectional view illustrating a main part of the outdoor unit including the components described above according to the present invention.

FIG. 4 shows another embodiment. The difference from the above-described embodiment is that water holes 5b respectively corresponding to the two water passages 10a are arranged in parallel at the center of the top plate 5. That is the provision. With such a configuration, water on the top plate 5 can flow down into the main body more quickly.

[0015]

With the outdoor unit as described above, since water on the top plate flows down into the main body, adhesion of water scale and the like to the front surface and both side surfaces of the outer body is reduced, and Since the surface is inclined to improve the flow of water and eliminate water pools, dirt on the top plate is reduced, and the appearance can be maintained in a good state for a long time.
