Description
前記ファンが収容され、前記ファンを囲繞するように形成される渦巻状の吐出通路と、前記ファンの駆動作用下に空気を吸入する吸入口と、前記吐出通路を流通する前記空気を外部へと吐出する吐出口とを有するケーシングと、
前記吐出通路に形成され、前記ファンを挟んで前記吸入口と対向した環状部から半径外方向且つ前記吸入口より離間する方向に傾斜すると共に、前記吐出通路の外壁に対して鋭角状に接合される傾斜面と、
を備え、
前記ファンの軸線と略平行な仮想線に対する前記傾斜面の角度が、前記吐出口側に向かって徐々に大きくなるように設定され、前記吐出通路の流路面積が、前記吐出口側に向かって半径外方向且つ前記吸入口より離間する方向に徐々に拡大することを特徴とする。
