A gap is provided between the peripheral surfaces of the parts to serve as a ventilation path, and a ventilation hole communicating with the gap is provided on the outer periphery of the insertion part of the inner ventilation tube, and a sound-absorbing material is housed at the end of the insertion part. It is. The outside air enters the inner ventilation tube, passes through the communication hole, and reaches the ventilation path and the outer ventilation tube to the inside of the room.In this process, sound is either absorbed by sound-absorbing materials, or bypassed through the communication hole and vented. The sound is reduced by passing through the road.

４の内面に設けた水返しである。 An inner ventilation tube 4 is inserted into the outer ventilation tube 2 from the outdoor side, and a flange 4a provided at the outer edge of the opening at one end (left end) of the inner ventilation tube is in contact with the outer wall surface of the wall surface W. A sealing material 5 is used to seal between the flange 4a and the outer wall surface. The inner ventilation tube 4 is held with a gap forming a ventilation passage 7 between the inner ventilation tube 4 and the outer ventilation tube 2 by protrusions 6, . . . that protrude from the inner surface of the ventilation tube. and inner ventilation pipe 4
A large number of ventilation holes 8 are provided on the outer periphery of the middle portion of the ventilation tube, and each ventilation hole is for communicating the inside of this ventilation cylinder and the ventilation path 7. The tip of the inner ventilation pipe 4 is closed, and a sound absorbing material 10 is housed between the end and the punching plate 9. 11 is a water return provided on the inner surface of the inner ventilation pipe 4.
内、外両換気筒２，４の材質としては、セラミ
ツクス、ALC（軽量気泡コンクリート）等のよう
な硬質材であつて、耐熱性及び吸音性に富んでい
るものが適宜選択される。 As the material for both the inner and outer ventilation tubes 2 and 4, a hard material such as ceramics, ALC (lightweight cellular concrete), etc., which has high heat resistance and sound absorption properties, is appropriately selected.

過程で減音される。 In the ventilation hole of the present invention configured as described above, outside air flows into the inner ventilation tube 4 from the outdoors, passes through the ventilation hole 8 as shown by the arrow, and then flows into the ventilation path 7.
From there, it flows into the room from the ventilation register 3 via the outside ventilation pipe 2. In addition, noise entering the inner ventilation tube 4 from outside is absorbed by the sound absorbing material 10 housed at the end of the ventilation tube, or is bypassed by the ventilation hole and reaches the ventilation path, reducing the noise in this process. be done.
内、外両換気筒２，４を吸音性の富んだセラミ
ツクスで製作すれば、両換気筒自体の吸音作用に
よつてさらに消音効果が期待できる。 If both the inner and outer ventilation tubes 2 and 4 are made of highly sound-absorbing ceramics, further noise reduction effects can be expected due to the sound-absorbing action of both ventilation tubes themselves.
