Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a device for partitioning an electrical component room and a blower side of a room air conditioner, and particularly to a ventilation device suitable for an outdoor unit of a separate room air conditioner.

[Background of the invention]

A conventional ventilation device will be explained with reference to FIGS. 1 to 3.

The box is made up of four stiff parts: 1 is the base, 2 is the outer box, 3 is the right side plate, and 4 is the left side plate. On the base 1, a compressor 5, a heat exchanger 6, electrical components 8, etc. are arranged. 7 is a cycle pipe that connects the compressor, heat exchanger 6, etc.

Reference numeral 9 denotes a blower motor, which is directly attached to the outer box 2, and 10 fans for the blower are mounted on the shaft.

11 prevents rain and water droplets from splashing on the compressor 5, electrical components 8, etc., and allows wind to pass through the heat exchanger 6 effectively.

This is a partition plate that acts as a guide. However, this partition plate 1
1 has an air hole lla which serves as a ventilation hole for drawing the heat generated by the compressor and electrical components into the blower side. Furthermore, an auxiliary llb flange is provided at the upper end.

From the air hole 11a opened in the partition plate 11, both types of elegance 8
1 on the blower side of the air hole 11a in order to enter the compressor 5 side.
A waterproof plate 2 is installed to allow wind to pass through as shown by arrow A, while rain falls onto the blower side as shown by arrow B. Note that the waterproof plate 12 is welded to the partition plate 11.

Due to the structure described above, if the waterproof plate 12 welded to the partition plate 11 is not sufficiently welded, vibrations from the blower or compressor 5 may cause noise, or rain may enter the weld and cause rust. There was a defect that caused the problem to occur and shortened the lifespan.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a ventilation device for a room air conditioner that blocks rain with a partition plate of the room air conditioner, protects electrical equipment from the rain, and allows air to cool the electrical equipment to pass through.

[Summary of the invention]

Bend the front end of the partition plate toward the blower to form a flange.
The vicinity of this upper end is narrowed into a convex shape in the opposite direction to the flange, and the upper side of the convex shape is shaped like the shape before narrowing, thereby allowing wind to pass through and rain to be blocked.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIG.

11' is a partition plate with the upper end bent toward the blower side, and 11b'
A flange is formed, a convex constriction part is provided in a part near the upper end of the opposite side of the flange 11b' on the electrical component side, and the top of this convex part is cut back to provide an air hole. In order to manufacture this shape, after squeezing it as shown in 110', the D part is returned as shown by arrow C to form the air hole 11a', and a mold with a shape that holds the D part from the electrical component 8 side is manufactured. and aperture part 1
There is also a method of forming the 10' section all at once, and either method may be used.

With the structure described above, there are no welded parts, so there is no rattling noise, and there is no rust due to rain, so it has a long life. Furthermore, since there is no need to separately make the waterproof plate 12, it is also inexpensive.

The wind passes as shown by arrow E, and the rain flows down as shown by arrow F.

〔Effect of the invention〕

According to the present invention, the upper end of the partition plate 11' is bent toward the blower side to form a flange, and the vicinity of the upper end of the partition plate 11' is narrowed into a convex shape toward the electrical compartment side, and the upper side of this squeeze is Since it is returned to its original shape to form an air hole, wind passes through it as shown by arrow E, and rain falls as shown by arrow F, so it has a long lifespan and is inexpensive.
