DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a sectional view showing a ventilation fan mounting device 1 according to the present invention mounted on a concrete wall W, and FIG. 2 is an overall perspective view of the ventilation fan mounting device 1. As shown in the figure, the ventilation fan attachment device 1 includes an L-shaped metal tubular body 5 that houses the ventilation fan 3.
In the tubular body 5, an inner opening 7 is formed inside the wall W (left side in FIG. 1), and a downward outer opening 9 is formed outside the wall W (right side in FIG. 1). . The ventilation fan 3 is a commercially available ordinary fan, and includes a fan F, a shutter S, a switch (not shown), and the like.

An exhaust filter 11 is attached to and removed from the inner opening 7 in the vertical direction (vertical direction in FIG. 1), and the inner opening 7 is covered by a metal lid 13 so as to be openable and closable. An intake filter 15 is attached in the lateral direction (left-right direction in FIG. 1) freely in the vicinity of the outer opening 9, and a wire net 17 is attached to the outer opening 9. The ventilation fan 3 is capable of rotating in forward and reverse directions, and is equipped with an intake filter 15 for intake and an exhaust filter 11 for exhaust.

The lower plate 5a of the cylindrical body 5 is, as shown in FIG.
It is sloped downward from the inside of the building to the outside so that rainwater can be easily discharged to the outside.

The lid 13 is attached to the cylindrical body 5 by a hinge 19. A double rising part 13 is provided around the lid 13.
A groove is formed by a and 13a, and the groove is formed on three sides except the lower side of the lid 13, and the rubber packing 13 is formed on the bottom of the groove.
b is attached. The bent portion 1 is on the lower side of the lid 13.
3c is formed, and the bent portion 13c is bent so as to open slightly outward from the position at a right angle.
A rubber packing 13d is attached to the outer surface of the.
When the lid 13 is closed, the edges of the upper plate and the side plate of the tubular body 5 are closed by the lid 1.
It fits in the groove of the peripheral part of 3 and adheres closely to the rubber packing 13b. On the other hand, the bent portion 13c of the lid 13 includes the lid 13 and the tubular body 5.
Cover the connecting part (hinge 19 etc.) with rubber packing 13
It comes into close contact with the inside of the cylindrical body 5 via d.

A metal fitting 13e (FIG. 2) is attached to the upper part of the lid 5, and a fastening metal fitting 21 for locking the metal fitting 13e is attached to the side plate of the tubular body 5. With this tightening member 21, even a woman or a child can easily lock the lid 13.

As shown in FIG. 1, the mounting member 2 is attached to the tubular body 5.
3 is attached by bolts 25, and the mounting bracket 23 is fixed to the wall W using bolts, anchor bolts, or the like.
Further, a rubber packing 27 is arranged between the tubular body 5 and the wall W.

FIG. 3 is an exploded view showing details of the intake filter 15. The filter 15 is of a cassette type and is constituted by a handle portion 15a, a filter mounting frame 15b having an opening portion, a cassette type filter 15c, and a net 15d stretched over the opening portion of the mounting frame 15b. Four filter pressing claws 15e are provided on the opening side of the filter mounting frame 15b. When the cassette type filter 15c is fitted into the opening of the mounting frame 15b, the surface of the cassette type filter 15c is pressed by the claws 15e, so that the filter 15
c is firmly fixed in the opening.

The cassette type filter 15c can be replaced depending on the application. For example, the filter is determined according to the environment in which the ventilation fan mounting device 1 is installed, such as dust only, one suitable for air pollutants, one that blocks harmful gases, and the like.

As shown in FIG. 3, the filter mounting frame 15b is inserted into a U-shaped frame receiver 29 provided below the tubular body 5. When the filter 15 is pushed laterally and completely inserted into the frame receiver 29, the holding springs 15f formed at both ends of the handle portion 15a are provided on the side plates of the tubular body 5 (not shown).
And the filter 15 is fixed. Mounting frame 15b
Since the inlet / outlet port 31 is located inside the wall W, the filter 15 for covering the outer opening 9 can be easily attached, detached, and replaced from the inside of the building.

The structure of the exhaust filter 11 is basically the same as that of the intake filter 15. However, the exhaust filter 1
Hooks 11f are attached to both ends of one handle 11a (FIG. 2). On the side surface of the cylinder body 5, a tightening fitting 33
Is attached, and the hook 11f is tightened with the tightening fitting 33
And fix the filter 11 so that it does not fall.

Now, with the above configuration, when exhausting,
The lid 13 is opened and the exhaust filter 11 is attached. The filter 11 is fixed by the tightening fitting 33. then,
For the intake filter 15, the cassette type filter 15c is removed and only the filter mounting frame 15b is inserted into the frame receiver 29. This improves the flow of the exhausted air and prevents dust and the like from accumulating in the groove portion of the frame receiver 29. When the ventilation fan 3 is rotated in this way, the air in the room becomes
After passing through the cassette type filter 11c, it is discharged from the outside opening 9 to the outside of the room. At this time, if the outside air is temporarily
Even if it enters the room through the inside, dust and contaminants are blocked by the filter 11c. Of course, when the indoor air is dirty, dust and contaminants in the indoor air are blocked by the filter 11c, purified, and exhausted.

On the other hand, at the time of intake, an intake filter 15 is attached, and the intake filter 11 is a cassette type filter 11.
Remove c and insert only the filter mounting frame. This blocks dust, pollutants, and harmful gases in the outside air.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications and applications can be considered. For example, although the above description has been described as a ventilation fan for buildings, the device of the present invention can be used not only for buildings but also for buildings, such as ships, airplanes, and vehicles, which generally require ventilation. Further, in the above description, the cylindrical body 3 is a square cylindrical body, but the shape of the cylindrical body is not limited to that, and for example, a cylindrical body may be used. Furthermore, the filters 11 and 15 may not be attached both, but only one of them may be attached depending on the application.

The cassette type filter described in the above embodiment can be used not only in the ventilation device but also in other air conditioners such as room air conditioners and general devices for performing intake and exhaust. In a conventional ventilation fan, air conditioner, or the like, the filter and its frame are fixed or integrated even though the filter is provided. Therefore, it is impossible to replace the filter itself according to the intended use, and there is no such idea. If the cassette type filter as in the above embodiment is used, the filter can be replaced according to the application. For example, it becomes easy to replace the filter depending on the environment in which the ventilation fan or the air conditioner is installed, such as dust only, one suitable for air pollutants, one for blocking harmful gas, and the like.
