Claims (1)
- 円板状の主板と環状のシュラウドとの間に円周方向に多数の羽根を配設した羽根車を渦巻き状のケーシング内に格納し、吸込み口から吸入した空気を前記羽根車の回転に伴う遠心力によって前記羽根車の径外方に向けて吹き出し、前記ケーシングの吐出し口から吹き出す遠心式ファンであって、
前記羽根車は前記羽根の一端側を主板で支持し、前記羽根の他端側を環状のシュラウドで支持し、前記環状のシュラウドは外縁部から中央に向かって曲面を形成し、中央には前記曲面に連接した円筒部を形成し、前記円筒部の上端が前記ケーシングの開口から上方に突出し、前記上端が外側に反った反り部を形成してベルマウス状に広がり、
前記ケーシングの前記開口の周縁には軸方向下方に突出する環状の突起部が形成され、該突起部は前記環状のシュラウドと所定の隙間を隔てて対峙し、
前記円筒部の前記上端の前記反り部の外径は前記ケーシングの前記開口の径よりも小さいことを特徴とする遠心式ファン。
