It is. In addition, h is a compressor arranged in the compressor room i on the right side of the partition plate b, and j is an outdoor heat exchanger.

However, in the conventional device, water droplets of melted snow and rain water are guided by the guide groove g and flow down to the lower end of the guide groove g.
Since the water overflows from the lower end and flows down the surface of the front plate e to be discharged to the outside, the surface area of the front plate that serves as the water droplet discharge passage below the guide groove g is susceptible to corrosion, which reduces the appearance. It is a shame that it cannot be kept beautiful for a long period of time.

Therefore, the present invention has been made in view of this point, and by providing drainage holes that communicate with the inside of the main body at appropriate locations in the guide groove as described above, water droplets guided by the guide groove can be removed from the main body from the guide groove. Water is drained internally, thereby preventing damage to the blower fan and burnout of the blower fan motor due to freezing of accumulated water across the air outlet and the blower fan, while maintaining the beautiful appearance of the main body for a long period of time. It is aimed at points.

Further, a guide groove portion 8 is formed on the outer periphery of the air outlet 7 of the front plate 6 by recessing the outer periphery of the air outlet 7.
The guide groove portion 8 is configured to guide water droplets of melted snow or rainwater from the upper surface of the outdoor unit main body 1 to the lower part along the outer periphery of the air outlet 7.

As shown in an enlarged view in FIG. 3, the guide groove portion 8 has drainage holes 9, which communicate with the interior of the outdoor unit main body 1, provided in the upper and lower ends and at the left and right ends, respectively, in the horizontal direction. Note that 10 is an air outlet grille that covers the air outlet 7.

Therefore, in the embodiment described above, when melted snow water or rainwater from the upper surface of the outdoor unit main body 1 flows down the front plate 6 of the outdoor unit main body 1 to the lower part, these water droplets flow through the air outlet 7. It flows downward while being guided by the guide groove 8 on the outer periphery and is discharged into the outdoor unit main body 1 through the drainage hole 9 of the guide groove 8. This prevents these water droplets from accumulating across the air outlet 7 and the outdoor fan 4, and prevents damage to the outdoor fan 4 and burnout of the outdoor fan motor 5 due to freezing of these water droplets. will be done. Moreover, at that time, the water droplets guided to the lower part by the guide groove part 8 are
Water is discharged into the outdoor unit main body 1 through the drainage holes 9, . Therefore, the exterior of the outdoor unit main body 1 can be kept beautiful for a long period of time.

As for the shape of the guide groove part 8 and the drain hole 9, as shown in an enlarged view in FIG. Further, a drainage hole 9'' may be provided by vertically opening an appropriate portion of the guide groove portion 8''.

In addition, Figures 5 and 6 show two outdoor fans.
A second embodiment is shown in which the present invention is applied to a separate outdoor unit. It should be noted that the same parts as those in the first embodiment are given the same reference numerals with a ``''' and their explanation will be omitted. In FIG. 5, inside the outdoor unit main body 1', two outdoor fans 4'a, 4'b and outdoor fan motors 5'a, 5'b are installed vertically on a reinforcing plate 3'. In addition, air outlet ports 7' corresponding to the outdoor fans 4'a, 4'b are provided on the front plate 6' of the outdoor unit main body 1'.
a and 7'b are provided above and below. Further, a guide groove portion 8' is provided in common on the outer periphery of the air outlet ports 7'a and 7'b.
