Next, the duct piping of the ventilator of this configuration,
The drain pipe construction and the ventilation grill attachment work will be described.

At the time of piping, first, the connecting portion 13 of the thin portion 12 which covers the drain pipe connection hole 3 of the flange member 1 is removed using a nipper or the like, and the drain pipe connection hole 3 is removed by the drain pipe 9. Make it ready for insertion. Then, the drain pipe 9 is inserted into the drain pipe connection hole 3, and is inserted into the cylindrical hole 10 a of the drain pipe connection cylindrical portion 10. The drain pipe 9 has a cylindrical hole 1 formed by a drain pipe fixing projection 14 by the elastic force of the drain pipe 9 itself.
0a, and is also held by the cutting portion of the connecting portion 13. In this state, the flange member 1 is mounted on the indoor ventilation opening 16 of the ceiling 5 with the mounting screw 6. At this time, the ventilation duct 4 and the spring claw 2 of the flange member 1 are locked, and the connection between the flange member 1 and the duct 4 is established. Thereafter, the drain pipe 9 is pulled downward,
Appropriate length (about 10 mm tube section 10 for drain pipe connection)
(Dimension projecting from the lower surface of the drain pipe 9), and the length of the drain pipe 9 is adjusted. Then, the sealing member 11 is
Is wound into the pipe hole 10a of the drain pipe connecting tube section 10 from below, whereby the tip of the drain pipe 9 is connected to the drain pipe connecting tube section 10 by the drain pipe fixing projection 14 and the connecting section 13. It is securely fixed by the cutting part. In particular, the cut portion of the connecting portion 13 cuts into the seal member 11 to prevent the drain pipe 9 from being detached from the drain pipe connecting tubular portion 10. Finally, by fixing the grill member 7 to the flange member 1 with the fixing screw 8, the flange member 1 is covered, and the work of mounting the ventilation grill is completed.

In this way, the connection between the ventilation duct 4 and the flange member 1 and the connection between the drain pipe 9 and the drain pipe connection cylinder portion 10 of the flange member 1 are made, and the drain pipe 9 is connected to the indoor ventilation port 16. Piped downhill toward.

As described above, the ventilating apparatus according to the present embodiment has a ventilation fan 15 for blowing air, an indoor ventilation port 16 located below the ventilation fan 15, and a ventilation connection between the ventilation fan 15 and the indoor ventilation port 16. A duct 4, a drain pipe 9 communicating the ventilation fan 15 and the indoor ventilation port 16 with a downward gradient toward at least the indoor ventilation port, and a drain pipe connection hole 3 penetrating the drain pipe 9; A flange member 1 attached to an indoor ventilation opening 16; a cylindrical hole 10a having a diameter hole into which the drain pipe 9 can be inserted; and the cylindrical hole 10a
A drain pipe fixing projection 14 disposed therein; a drain pipe connecting cylinder 10 extending in the drain pipe connecting hole 3 of the flange member 1; and the flange member 1 covering the flange member 1. 1 and a grill member 7 forming a ventilation grill.

That is, in the ventilating apparatus of this embodiment, the drain pipe connecting cylindrical portion 10 having the cylindrical hole 10a having an inner diameter through which the drain pipe 9 can pass through the drain pipe connecting hole 3 formed integrally with the flange member 1 is extended. A drain pipe fixing projection 14 is provided so that the drain pipe 9 can be fixed to the cylindrical hole 10a of the drain pipe connecting cylindrical part 10.

Therefore, the ventilation fan 15 and the indoor ventilation port 16 located below the ventilation fan 15 are connected by the ventilation duct 4, and the drain pipe 9 is inserted through the drain pipe connection hole 3 of the flange member 1 to connect the drain pipe. Tube part 1
0, the ventilation fan 15 and the indoor ventilation opening 16 communicate with each other at least downwardly toward the indoor ventilation opening 16, and the flange member 1 can be attached to the indoor ventilation opening 16 and covered with the grill member 7.

For this reason, after connecting the ventilation fan 15 and the drain pipe connecting cylindrical portion 10 of the flange member 1 with the drain pipe 9, the flange member 1 can be attached to the indoor ventilation opening 16, and the drain pipe 9 and the flange member The connection with the first drain pipe connection tubular portion 10 can be reliably performed, and the drain pipe 9 can be reliably piped downhill toward the indoor ventilation port 16. Therefore, the drain from the ventilation fan 15 flows smoothly toward the indoor ventilation port 16 through the drain pipe 9, and the drain discharge performance is improved. Moreover, there is no need to provide any special means such as an inspection port for checking the piping condition of the ventilation duct 4 and the drain pipe 9, and the piping work of the ventilation duct 4 and the drain pipe 9 and the installation of the ventilation grill are required. Work can be done easily.

Further, in the method of constructing the ventilation device of the present embodiment, after the drain pipe 9 is passed through the drain pipe connection hole 3 of the flange member 1, the flange member 1 is attached to the indoor ventilation opening 16 and the drain pipe 9 is mounted. To the indoor side,
The length of the drain pipe 9 is adjusted, and the drain pipe 9 is fixed to the drain pipe connecting tubular portion 10. That is, the flange member 1
A state in which the drain pipe 9 is inserted into the drain pipe connecting hole 3 and the drain pipe 9 is inserted by an appropriate length into the cylindrical hole 10a of the drain pipe connecting cylindrical portion 10 extending in the drain pipe connecting hole 3. After the flange member 1 is attached to the indoor ventilation port 16, the length of the drain pipe 9 is adjusted by appropriately cutting the drain pipe 9 that protrudes from the drain pipe connecting tube portion 10. is there.

Therefore, when the drain pipe 9 is connected to the drain pipe connecting cylindrical portion 10 of the flange member 1,
The length of the drain pipe 9 can be adjusted, and there is no danger that the drain pipe will become excessive between the ventilation fan and the flange member and break the slope, so that the drain pipe 9 is surely directed from the ventilation fan 15 to the indoor ventilation opening 16. Can be piped downhill. Moreover, the connection between the drain pipe 9 and the drain pipe connecting tubular portion 10 of the flange member 1 can be ensured by the drain pipe fixing projection 14 and the cut portion of the connecting portion 13. As a result, highly reliable piping work of the drain pipe 9 can be performed extremely easily.

Furthermore, in the flange member 1 of the ventilating apparatus according to the present embodiment, a thin portion 12 is provided in the cylindrical hole 10a of the drain pipe connecting cylindrical portion 10 in consideration of the case where the drain pipe is not constructed. I have. Accordingly, by punching the thin portion 12 formed to plug the cylindrical hole 10a of the drain pipe connecting cylindrical portion 10 as necessary, the drain pipe 9 and the drain pipe of the flange member 1 are formed in the same manner as described above. Since the connection with the connection tube portion 10 can be reliably performed, and the drain pipe 9 can be piped downwardly toward the grill member 7, the same effects as described above can be obtained. In addition, when the drain pipe for drain discharge is unnecessary, the thin portion 12 can keep the cylindrical hole 10a of the drain pipe connecting cylindrical portion 10 plugged and closed, and can be used according to the application. Become.

In the above embodiment, the ventilation grill mounted on the ceiling 5 has been described. However, if the ventilation system requires the installation of ventilation duct piping and drain discharge piping, the ventilation wall mounted on a normal wall is required. Of course, it can also be applied to grills.
