２を使用しない場合は、排気用ダクト２１が風胴
４のフランジ部８に直接ボルト締めされる。 As shown in FIG. 2, such a blower is used by being connected between exhaust ducts 20 and 21 in the attic, etc., but a flexible duct 22 is used for ease of installation and for prevention of vibration and noise of the blower. used through. Here, the flexible duct 22 is
Furthermore, tape or rivet 2 is attached to the companion flange 23.
4 is caulked and fixed, and connected via this companion flange 23. In addition, the above flexible duct 2
2 is not used, the exhaust duct 21 is bolted directly to the flange portion 8 of the wind barrel 4.
従つて、フレキシブルダクト２２を使用するう
えで相フランジ部２３はなくてはならないもので
あり、また一体絞り風胴３及び４はフランジ部８
を必要とするため製作に時間を要していた。 Therefore, when using the flexible duct 22, the companion flange part 23 is indispensable, and the integrated throttle wind cylinders 3 and 4 have the flange part 8.
It took time to manufacture because it required
本考案はこのような点に鑑み、相フランジを使
用しなくても済むこと、及び風胴の製作を容易に
することを目的としてなされたものであつて、以
下第３図及び第４図に基づき実施例で説明する。 In view of these points, the present invention was made with the aim of eliminating the need to use a companion flange and making it easier to manufacture the wind cylinder. Examples will be explained based on this.
第４図において、１０及び１１は本考案に係る
一体絞り風胴で、それぞれダクトフランジ部７を
有する一方、排気用ダクト接続部はストレート化
し、ストレート部１２を20〜40mm程度残してフラ
ンジ１３を溶接して固着し、前記相フランジ２３
を兼用するようにしてある。尚、羽根車２及び電
動機１は従来と同様に取付足５を介して風胴４に
溶接され取付板６にボルト締めされ、また風胴１
０と１１とは互いのダクトフランジ部７でボルト
締めされて固定される。 In FIG. 4, reference numerals 10 and 11 are integrated throttle wind cylinders according to the present invention, each having a duct flange portion 7, while the exhaust duct connection portion is straightened, leaving a straight portion 12 of about 20 to 40 mm and a flange 13. The companion flange 23 is fixed by welding.
It is designed to be used for both purposes. Incidentally, the impeller 2 and the electric motor 1 are welded to the wind cylinder 4 via the mounting foot 5 and bolted to the mounting plate 6 as in the conventional case, and the impeller 2 and the electric motor 1 are
0 and 11 are bolted and fixed at each other's duct flange portions 7.
かかる構成による送風機においては、排気用ダ
クト２０及び２１間に接続する場合、第４図に示
すように、フレキシブルダクト２２を風胴１０の
ストレート部１２に相フランジなしで直接テーピ

接続固定できる。 In the blower having such a configuration, when connecting between the exhaust ducts 20 and 21, the flexible duct 22 is directly taped or riveted to the straight part 12 of the wind barrel 10 without a companion flange, as shown in FIG. The connection can be fixed by
Further, when the flexible duct is not used, the exhaust duct 21 can be inserted into the straight part 12 of the wind barrel 11 as shown in the figure, and connected and fixed by bolting to the flange 13.
以上説明したように本考案においては、風胴の
両端部にストレート部を成形すると共に、このス

優れた効果がある。 As explained above, in the present invention, a straight part is formed at both ends of the wind barrel, a flange part is welded and fixed to the straight part, and both ends of the wind barrel are connected to the flexible duct or the connection part of the exhaust duct. Therefore, the connection work for both the flexible duct and the exhaust duct becomes easy, and furthermore, the wind cylinder has excellent effects such as easier integral drawing.
