Description

[Detailed description of the device]

[0001]

[Industrial application] The mounted aerator of the present invention is used for indoor ventilation of a building.

[0002]

2. Description of the Related Art A ventilator for indoor ventilation is used by fitting it into a mounting hole formed in a wall of a building. However, the conventional cylindrical ventilator is merely composed of a cylindrical main body.

[0003]

In such a conventional ventilator, the dust and oil accumulated in the upper part of the main body tube and the outlet are dissolved into rainwater and flow down as dirty water when it rains. As it flows down the outer wall of the building, the traces of the runoff become black stains and remain on the outer wall, which spoils the beauty of the outer wall within a short period of time.

The present invention can provide an attached ventilator in which the appearance of the outer wall can be maintained for many years with few traces of dirty water flowing down on the outer wall of the building.

[0005]

SUMMARY OF THE INVENTION An attached aerator according to the present invention is provided on the outer periphery of a lower half portion of an outward flange formed at a front end portion of an opening of a cylindrical main body tube and extends radially in the outward flange.
The structure is provided with a guide frame for receiving water, which is composed of an expanding frame flange and a collar projecting forward formed on the outer periphery of the frame flange.

[0006]

[Operation] The mounting aerator of the present invention is installed by penetrating it through the wall of the building.

By doing so, the air in the room is exhausted from the main body cylinder to the outside of the room.

Further, the dust and oil accumulated on the outward flange of the main body cylinder and the guide frame become dirty water in rainy weather, and the dirty water on the outward flange once flows down into the guide frame for receiving water, and becomes dirty water in the guide frame. Although they flow down together, the dirty water drops from the edge of the collar projecting forward of the guide frame, and therefore hardly flows down the outer wall surface of the building.

EXAMPLES Example 1 FIGS. 1 to 4 show an example of an attached ventilator according to the present invention.

In the figure, reference numeral 1 is a cylindrical main body cylinder,
An outward flange 2 is formed on the peripheral edge of the front end portion of the opening, and a lower half portion of the rear end opening portion 1b is closed by a half rear plate 3.

At the front end opening of the main body cylinder 1, a louver plate 4 is attached by being fixed to the outward flange 2 of the main body cylinder 1 by a rivet 5, and the worm plate 4 and the outward flange 2 of the main body cylinder sandwich the insect repellent net. 6 is attached.

A plurality of louver vent holes 7a in the shape of a horizontally elongated slit are formed in the vertical direction in the louver plate 4 by forming a plurality of vertically inclined cut-and-raised louver pieces 7 in the vertical direction.

A guide frame 8 projecting forward is provided on the lower half portion of the outward flange of the main body cylinder.

[0014] The guide frame, there as forming a collar 8b that protrudes slightly enlarged forward on the outer periphery of the semicircular enlarged frame flange 8a projecting radially expanded diameter <br / > Frame flange 8a with rivet 5
It is attached to the outward flange of the main body cylinder by stopping.

Further, the collar 8b has a protruding amount by which dirty water in exhaust or rain falls without passing through the outer wall surface, and a bent water stop slightly inclined forward to the upper left and right ends of the frame flange 8a. A piece 9 is formed.

The guide frame may be formed integrally with the outward flange of the main body cylinder.

The ventilator of this embodiment is fitted into a mounting hole 11 of a wall 10 of a building as shown in FIG. 3, and is properly caulked between the outer peripheral edge of the flange of the main body cylinder and the wall surface for sealing.

Dirty air containing oily smoke and the like from inside the room enters the main body cylinder 1 through the rear end opening 1b, and the air is discharged obliquely downward and forward from the louver ventilation hole 7a of the glass plate.

Further, accumulate dust and oil or the like on the inner surface of the outward flange second surface and guide frame 8 during use, but they become dirty water during rainy weather, the dirt enlarged frame flange and collar <br Everything is temporarily stored in the guide frame by and . However, since the guide frame projects forward from the outer wall surface, it is unlikely that dirty water will flow through the wall, and almost no trace of dirty water will flow under the ventilator attachment point on the outer wall surface. Absent.

Further, the guide frame 8 has a collar 8b formed on the outer periphery of a frame flange 8a having a diameter larger than that of the outward flange of the main body cylinder, so that water flowing down the wall near the outer periphery of the upper half of the outward flange can be prevented. Once received, water can be dropped from the lower edge of the collar.

<Embodiment 2> FIGS. 5 to 7 show another example of the attached ventilator according to the present invention.

In this embodiment, a hood 12 is provided on the front surface of the flange of the main body cylinder.
Reference numeral 2 is a hemispherical shell having an open lower portion, and a guide frame 8 is provided in the lower half portion of the flange as in the embodiment.

Since the main body cylinder of this embodiment has the same structure as the main body cylinder of the first embodiment, the respective constituent parts are denoted by the reference numerals and the description thereof is omitted.

Since the attached ventilator of the second embodiment is provided with the hood, it is possible to prevent rain and wind from flowing back into the room.

Further, dirt water such as dust on the surface of the hood, dust on the inner surface, dust on the inner surface, oil, etc. dissolved in rainwater also flows down to the guide frame 8 and is transmitted from the lower edge of the guide frame to the outer wall surface of the building. Without falling, there is almost no trace of dirty water on the outer wall.

[0026]

[Advantage of the Invention] Since the mounted aerator of the present invention is provided with the above-mentioned guide frame, it is unlikely that traces of dirty water will be left under the aerator mounting location on the outer wall of the building, and the appearance of the outer wall will be improved. Can hold for many years.
