3 and 4 show a first embodiment of the present invention.
FIG. 5 illustrates a second embodiment of the present invention, which will be described below.

The first embodiment is a ventilation port a provided in a pipe 6 having a ventilation function and protruding from a wall 5, and the ventilation port a is provided with a cylindrical portion 1 fitted into the pipe 6. And a ventilating body 2 fitted on the front side of the mounting body 4, and a pipe member 6 protruding from the wall 5 around the cylindrical portion 1 on the rear side of the mounting body 4. Is provided, and a contact surface 10 is provided around the concave portion 7 on the back surface of the mounting body 4 so as to contact the wall 5.

Further, a cylindrical tubular portion 1 is employed as the tubular portion 1, and a rectangular tubular attaching body 4 and a ventilating body 2 are employed as the attaching body 4 and the ventilating body 2.

Further, the cylindrical portion 1 and the mounting body 4 are formed separately. Further, the tubular portion 1 and the mounting body 4 are
Peripheral flange 8 integrally formed by pressing or the like on the outer peripheral surface of
The peripheral flange 8 and the rear surface of the mounting body 4 are fixed by a fixing member 9 such as a rivet so as to be integrated.

The recess 7 is formed on the back surface of the mounting body 4 by press working or the like.
The cylindrical flange 1 and the mounting body 4 are integrated with each other. In addition, other than the method of fixing with the fixing member 9 such as a rivet, for example, a method of fixing by welding or the like may be adopted.

The ventilation body 2 has a configuration in which a window member 15 having the ventilation window 3 is attached to the front side of the cylindrical portion 13. Further, the ventilation body 2, the cylindrical portion 13, the window member 15, and the ventilation window 3 are also integrally formed by press working or the like.

The ventilator 2 is provided so as to be fitted into the attachment 4. The ventilation body 2 and the mounting body 4 are detachably provided by a fastening member 18 such as a screw.

In the drawing, reference numeral 11 denotes a caulking material for preventing intrusion of rainwater and the like, and 16 denotes a retaining member for preventing the ventilation port a from falling out of the pipe 6.

By the way, in the technical field of the vent,
How the dew condensation water which accumulates in the ventilation port a and the pipe material 6 and the liquid 12 such as oil which accumulates in the ventilation port a and the pipe material 6 when the ventilation port a is used for ventilation and exhaust of a kitchen, for example. It may be a problem whether the liquid is discharged. For example, in the first conventional example and the first embodiment, a drain 17 for discharging the liquid 12 is provided at a lower portion of the front surface of the ventilation member 23 and the ventilation body 2.

However, in the case of the first conventional example, the liquid 12 enters and accumulates in a gap between the overlapping portions of the peripheral flange 28 of the cylindrical portion 26 and the flange 22 of the ventilation member 23, and the liquid 12 allows the vent 12 wall
There is a problem that 24 is corroded. In particular, in the case of the first conventional example, the liquid 12 easily accumulates in the space surrounded by the ventilation member 23, the flange 21, the wall 24, and the caulking material 29, and the corrosion problem is large.

Therefore, in the first embodiment, at the overlapping portion of the peripheral flange 8 of the cylindrical portion 1 and the concave portion 7 of the mounting body 4, the concave portion 7 is overlapped with the concave portion 7 being located closer to the wall 5 than the peripheral flange 8. The liquid 12 collected in the pipe 6 and the ventilation port a passes from the inner surface of the cylindrical portion 1 through the peripheral flange 8 provided in the cylindrical portion 1,
, The air directly reaches the lower inner surface of the ventilation body 2 and is discharged from the drain 17. In other words, a configuration is employed in which there is no gap for the liquid 12 to enter the discharge path of the liquid 12.

Since the first embodiment is configured as described above,
When the tubular portion 1 is fitted into the tube 6, a portion projecting outward from the wall 5 of the tube 6 is inserted into a ring-shaped concave portion 7 provided on the back of the attachment 4. Abutment surface
10 and the wall 5 can be brought into contact with each other, and the ventilation port a is provided in the pipe 6 in a stable state without swinging. It is a ventilation port that excels in practicality in which the caulking material 11 can be easily provided between them and excellent workability in mounting.

Further, by removing the ventilation body 2 of the ventilation port a attached to the pipe member 6 from the attachment body 4, the inside of the ventilation port a and the interior of the pipe member 6 can be easily cleaned. It becomes a vent.

The ventilator 2 can have any shape as long as the ventilator 2 can be fitted into the mounting member 4. Therefore, the ventilator 2 having a desired exhaust / ventilation function is selected. It is a ventilation port with excellent practicality and versatility.

Further, since the cylindrical portion 1 and the mounting body 4 are formed as separate bodies, and the two are overlapped by the peripheral flange portion 8 and the concave portion 7 so as to be connected to each other, the concave portion on the back portion of the ventilation port a is adopted. 7 can be easily formed by an integral forming method such as press working, and is a ventilation port excellent in practicality and productivity. When the tubular portion 1 and the mounting body 4 are formed as an integral body, for example, when the tubular portion 1 is cylindrical and the mounting body 4 is a square tubular shape, for example, the cylindrical portion 1 and the mounting body 4 are formed.
When the shape is greatly different from the above, the formation of the concave portion 7 causes the cylindrical portion 1 and the mounting body 4 to be greatly distorted.

Further, in addition to the formation of the concave portion 7, the formation of the peripheral flange portion 8 and the formation of the window member 15 can be easily performed by an integral forming method such as press working, and is excellent in practicality and productivity. Vent vents.

Further, since the recess 7 is overlapped with the peripheral flange 8 being located on the wall 5 side, the liquid 12 such as dew condensation accumulated in the pipe 6 or the cylinder 1 is discharged from the cylinder 1. After passing through the inside of the ventilator 2,
And can be reliably discharged from the drain 17 provided in the ventilator 2,
12 is a ventilation port excellent in practicality and drainage, which does not accumulate in the overlapping portion of the cylindrical portion 1 and the mounting body 4.

The second embodiment has a construction which can be adopted when the cross-sectional shapes of the cylindrical portion 1 and the mounting body 4 are similar (both are cylindrical in the second embodiment). A ring-shaped concave portion 7 is formed integrally with the cylindrical portion 1 by pressing or the like, and has a rear surface portion of the mounting body 4 and into which a tube material 6 protruding from the wall 5 can be inserted around the cylindrical portion 1. A contact surface 10 is formed integrally by press working or the like, and is provided on the rear surface of the mounting body 4 and around the concave portion in contact with the wall 5.

In the second embodiment, since the concave portion 7 can be integrally formed when the cylindrical portion 1 and the mounting body 4 are formed, the productivity is further improved as compared with the first embodiment. .

The rest is the same as in the first embodiment.
