Abstract
Description
図1は本発明の実施の形態の送風装置を示す側断面図、図2は同送風装置のケーシング吸込口からの平面図である。送風装置1は直方体状(たとえば長さ270mm×幅270mm×高さ200mm)の外郭を成すフレーム2を備え、フレーム2の下面にはフレーム吸込口3を設け、側面にはフレーム吹出口4が設けられている。
図4は、本発明の実施の形態の送風装置のダクト接続部の斜視図である。図4に示すように、ダクト接続部19は排気ダクト6の荷重による変形などに耐え得る剛性を持つよう金属製である。ダクト接続部19のフレーム吹出口4側は、フレーム吹出口4よりも大きく拡径され、フレーム吹出口4よりも大きな開口面積となっている。ダクト接続部19内には、一端がダクト接続部19の円形の断面形状のダクト接続口18に接合される樹脂製の内周ダクト20が設けられている。このようにダクト接続部19は、ダクト接続口18を有する外周部品と、フレーム内吹出部17につながる内周部品とを備えた二重構造である。これにより、ダクトの荷重が付加されるダクト接続口18を有する外周部品を、金属などの剛体により製作して部品強度を向上することができる。また外周部品は、フレーム内吹出部17とつながるため、曲面形状となる内周部品を樹脂成形などにより容易に作製できる。
