Description

[Detailed description of the invention] This invention relates to an air guider for an outdoor unit of a separate type air conditioner, and one of its purposes is to reduce assembly man-hours during manufacturing and at the same time improve after-sales serviceability after installation. It is something to do.

In general, maintenance and inspection work after installation is a very important element in the outdoor unit of a separate air conditioner. While
It is often used to damage various electrical equipment. However, in the exterior case a of a conventional outdoor unit, the top surface, both short sides c, the compressor room cover d, and the airflow section exterior front plate e are integrated by spot welding, etc., so it is difficult to inspect the electrical components inside the compressor room. Even if the outer case a
All of the parts had to be removed, which made the work extremely difficult, and at the same time, it was very dangerous to inspect while driving because the fan would rotate.

In addition, if emphasis is placed on after-sales service after installation, it is desirable to have a structure that opens only where inspection is required.In such a case, the exterior case must be divided, which inevitably increases the number of parts.
This increases the number of assembly steps during manufacturing.

The present invention eliminates the above-mentioned contradictory drawbacks of the prior art.

Hereinafter, the present invention will be explained with reference to FIGS. 1 to 5 of the accompanying drawings showing one embodiment thereof.

In the figure, 1 is the outdoor unit main body, and the board 2
and an exterior case 3, inside which a shielding plate 4 welded and fixed onto the substrate 2 is disposed, dividing the interior into an airflow chamber 5 and a compressor chamber 6. In the airflow chamber 5, a heat exchanger 7, a fan 8, a fan motor 9, and a motor mount 10 are arranged, and in the compressor chamber 6, a well-known refrigeration cycle is installed together with the heat exchanger 7. A compressor 11 and electrical components 12 for controlling the operation of the fan motor 9, compressor 11, and the like are provided. Here, the exterior case 3 has a top surface 3a forming the ceiling of the airflow chamber 5 and the compressor chamber 6, as shown in FIG.
Side surfaces 3b, 3b formed on both sides of this top surface 3a
It is formed into a substantially inverted U-shape, and both sides in the airflow direction shown by arrow A in FIG. 3 are open. One opening surface of this exterior case 3 faces the heat exchanger 7, and the other opening surface faces the fan 8.
A cover 13 closes the opening on the compressor chamber 6 side of the exterior case 3, and is fixed to the shielding plate 4, the substrate 2, and the exterior case 3 with screws 15. 14 is the outer case 3 similar to this cover 13.
The air guider closes the opening on the airflow chamber 5 side, and is fixed to the shielding plate 4, the substrate 2, and the exterior case 3 with screws 15 using engagement means so that the number of screwed parts is minimized. Here, the air guider 14 made of a synthetic resin material includes a fan shroud 14a, a fan guard 14b, and an exterior front plate portion 1.
4c, and a hook portion 14d formed at the lower part of the exterior front plate portion 14c has a structure to sandwich the rising flange 2a of the substrate 2, and The hook portions 14e formed on the upper part are inserted into the plurality of notches 3e of the inwardly bent flange portion 3d of the exterior case 3, and by moving the air guider 14 in the horizontal direction, the air guider 1
4 is fixed so as to sandwich the flange portion of the outer case 3.

In the above configuration, since the upper part of the air guider 14 is not fixed to the outer case with screws, it can freely expand and contract thermally, and the air guider 14 made of synthetic resin will not be deformed due to thermal expansion. Even if the outdoor unit is accidentally dropped while being transported in a closed state, the exterior case 3 will be deformed instantaneously, but the air guider 14 will not be deformed and will not break.

As is clear from the above embodiments, the outdoor unit of the separate air conditioner according to the present invention includes a shielding plate inside the outdoor unit main body, which is composed of a substrate having a rising flange on the periphery and a U-shaped exterior case. forming an airflow chamber and a compressor chamber;
A heat exchanger is arranged along one long side of the substrate in the airflow chamber, and the airflow for the heat exchanger passes through the heat exchanger and blows out to the long side side generating airflow on the opposing surfaces. A fan motor directly facing the heat exchanger,
Equipped with a fan and synthetic resin air guider,
This air guider is composed of a cylindrical fan shroud portion that covers the fan, a fan guard that prevents fingers from being inserted into the fan side, and an exterior front plate portion that has a plurality of hook shapes at the upper and lower ends. Electrical components for controlling the operation of the compressor, fan motor, etc. are provided in the compressor room, and a cover for closing the compressor room is removably provided on a surface of the compressor room adjacent to the air guider section, and the A flange bent inward is provided around the opening of the air guider and cover mounting surface in the exterior case, and a plurality of notches are provided at predetermined intervals on the upper side of the flange, so that the lower hook of the air guider can be connected to the board. Insert the upper hook part of the air guider into the notch of the flange provided on the upper side of the outer case, and move the air guider horizontally so that the air guider pinches the flange of the outer case. Even if the cover is removed during after-sales service after installation, a ventilation circuit is formed on the airflow chamber side, so a ventilation test can be performed, and the current value during air conditioning operation and the refrigeration cycle can be checked. It has various advantages such as being able to measure high and low pressure values.
