本発明は、建物の厨房、浴室1便所等の換気を行うため
に外壁に設けられている換気孔構造に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a ventilation hole structure provided in an outer wall for ventilation of a kitchen, bathroom, toilet, etc. of a building.
(従来の技術)
従来の換気孔構造は、例えば、実公昭55−7769号
公報等に記載されているように、直管状の換気パイプが
用いられ、該換気パイプの換気入口側の端部が換気ダク

目地に重なるのを避ける等の理由により、換気孔の大き
さが制限され、換気孔を換気ダクトの口よりも小さくせ
ざるをえない場合がある。そのような場合、従来一般に
は、換気パイプの径を、換気入口から換気出口に向けて
絞り、換気入口側の太い端部を換気ダクトに接続すると
共に、換気出口側の細い端部を外壁の換気孔に接続する
ことになる。However, when opening ventilation holes in the exterior wall, the size of the ventilation hole is limited due to reasons such as avoiding overlapping the ventilation hole with the joints of the exterior wall, and the ventilation hole must be made smaller than the opening of the ventilation duct. There are cases. In such cases, conventionally, the diameter of the ventilation pipe is narrowed from the ventilation inlet to the ventilation outlet, the thick end on the ventilation inlet side is connected to the ventilation duct, and the narrow end on the ventilation outlet side is connected to the outside wall. It will be connected to the ventilation hole.
(発明が解決しようとする課題)
しかしながら、このような従来の換気孔構造にあっては
、換気パイプの径が換気出口に向けて絞られているので

気の排気に伴って大きな気流音が発生するという問題が
あった。(Problem to be solved by the invention) However, in such a conventional ventilation hole structure, the diameter of the ventilation pipe is narrowed toward the ventilation outlet, so the air introduced from the ventilation duct is The pressure increases as the air flows through the pipe, and the high-pressure air is exhausted to the outside from the ventilation outlet of the ventilation pipe. Therefore, there is a problem in that large airflow noise is generated as the air is exhausted.
そこで、本発明の建物の換気孔構造は、上記従来の問題
に着目し、換気孔を換気ダクトの口径よりも小さくした
場合でも、気流音を和らげながら排気できるようにする
ことを目的としている。Therefore, the ventilation hole structure of a building of the present invention focuses on the above-mentioned conventional problem, and aims to enable exhaust while reducing air flow noise even when the ventilation hole is made smaller in diameter than the ventilation duct.

A plurality of ventilation vibrators are formed with a size smaller than the ventilation inlet, and an intermediate chamber having a vertical cross-sectional area larger than the ventilation inlet is formed between the ventilation outlet and the ventilation inlet. The end on the inlet side is connected to a ventilation duct, and the end on the ventilation outlet side of each ventilation pipe is connected to a ventilation hole provided in the outer wall.

、気流音を和らげながら排気することができる。(Function) In the ventilation hole structure of a building according to the present invention, a plurality of ventilation outlets of the ventilation pipe are formed with a size smaller than the ventilation inlet, and between the ventilation outlet and the ventilation inlet, there is provided a structure that is vertically longer than the ventilation inlet. Since an intermediate chamber with a large area is formed, when the air introduced from the ventilation duct flows through the ventilation vibrator, the pressure is first lowered in the intermediate chamber, so that the lower pressure air flows from the ventilation outlet of the ventilation pipe. It will be exhausted outside. Therefore, air can be exhausted while reducing air flow noise.
また、換気出口が複数設けられていることで、空気を各
換気出口から分散して効率良く排気できる。Furthermore, by providing multiple ventilation outlets, air can be dispersed from each ventilation outlet and exhausted efficiently.
