される。In the above configuration, if the indoor air becomes polluted, if the duct ventilation fan 104 is turned off, the indoor air will be turned off by the duct ventilation.
Suctioned into
It is discharged outside from 03. On the other hand, outdoor noise tries to enter the room through the gear 211 part 103, but it hits the soundproofing material 102 inside the soundproofing device and is absorbed to a large extent, and the noise that enters the room: is considerably reduced.

の欠点を有していた。By the way, the soundproofing device main body 101 does indeed receive noise from outside the room.
Although its role is to prevent noise, the duct ventilation fan 104
This creates a great deal of resistance when exhausting indoor air, and with a duct ventilation fan that has a low air volume, it has the disadvantage of not being able to exhaust air outdoors. Ta.

It is a cylindrical main body that is rotatable about a shaft 3 and has a blade 5 to which a soundproofing material 4 is attached, and a gear lary portion on the outdoor side. FIG. 2 is a perspective view showing the shape of the blade 5. FIG. 3 shows an installation diagram of the main body 1 of the ventilation system, where 7 is a duct ventilation fan attached to the ceiling surface 8, and 9 is a duct forming a ventilation path from the duct ventilation fan 7 to the wall 10. be.

５に貼り付けた防音材４に当ってかなり吸収され、室内
に入ってくる吸音はかなり軽減される。When the indoor air becomes dirty in the above step 41'1', when the duct ventilation fan is operated, the indoor air is sucked into the duct ventilation fan γ, passes through the duct 9, and enters the main body 1. The blades 5 are rotated and the air is discharged from the gear assembly 6 to the outside. On the other hand, the sound from outdoors tries to enter the room through the gear assembly 6, but this is absorbed by the soundproofing material 4 attached to the blades 5 and is absorbed considerably. The noise absorption is considerably reduced.
ここで防音材４は羽根５に貼）付けられ、従来のように
固定された防音材よりも、風の抵抗をらまり受けないよ
うになっており、かつ騒音をも防止することができる。Here, the soundproofing material 4 is attached to the blade 5, and is less susceptible to wind resistance than a conventional fixed soundproofing material, and can also prevent noise.
