つた。BACKGROUND ART Conventionally, this type of duct ventilation fan has had a duct connection port configured as shown in FIG. 4, although no specific literature can be cited. i.e. 101
A tapered adapter 102 provided at the exhaust port of the ventilation fan body (not shown) is a duct connected to the adapter 101, and the adapter 101 and the duct 1
After connecting 02, it was fixed with tape 103 to prevent air from leaking from the connected portion.
考案が解決しようとする問題点
このような従来の構成では、非常にせまいダク
トスペースでテーピングしているためテーピング
作業がしにくいという問題点があつた。Problems to be Solved by the Invention In this conventional configuration, there was a problem in that taping was performed in a very narrow duct space, making it difficult to perform taping work.

ダクト６が挿入されている。Embodiment An embodiment of the present invention will be described below based on FIGS. 1 to 3. In the figure, 5 is the main body of the duct ventilation fan, and the exhaust port 7 is connected to the duct connection port 1.
An adapter 4 is attached. The duct connection port 1 has a cylindrical shape and includes an outer tube 2. The outer tube 2 is made of a rubber-like material that can be freely contracted, and the inner tube 3 is inserted into the outer tube 3 after being pushed open in advance. The inner cylinder 3 is made of a synthetic resin material, has a spiral shape, and is pulled out linearly by pulling the end thereof, and is finally removed. Note that a duct 6 is inserted into the inner cylinder 3 in advance.

とができる。 With the above configuration, by pulling out the inner cylinder 3, the outer cylinder 2 loses its support and returns to its original state, that is, its diameter becomes smaller, and it comes into close contact with the outer periphery of the duct 6, connecting the duct 6 to the duct connection opening. 1 without leakage, and dirty air from the main body 5 can be discharged outside through the adapter 4.
考案の効果
以上の実施例の説明より明らかなように本考案
によれば、本体とダクトとの接続がスパイラル状
の内筒を引き抜くことだけで可能となり、容易に
ダクト工事を行なうことができる。また内筒の内
径より細いダクトであれば、種々のダクト径を選
択することができ、その実用的効果は大きい。Effects of the Invention As is clear from the above description of the embodiments, according to the present invention, the main body and the duct can be connected by simply pulling out the spiral inner cylinder, and the duct work can be easily carried out. Further, as long as the duct is thinner than the inner diameter of the inner cylinder, various duct diameters can be selected, which has a great practical effect.
