Description
Claims (6)
- 少なくともエンジン(20)とファンを具備しているブロワ(10)の装置であって、
前記ファンは、ファン・ホイール(21)とファン入口(23)を囲んでいるファン・ハウジング(24)を具備していて、前記エンジン(20)と前記ファンは、ケーシング(11)により囲まれていて、前記ケーシング(11)は、前記ケーシング(11)の内部に設置された前記ファン入口(23)へ空気を導入するための空気入口を設けられ、その結果前記空気流が、前記ファン入口(23)に流入し、また送風管(14)を経てブロワから流出する前に、前記ケーシング(11)の前記空気入口から前記ファン入口(23)への空気流が、前記ケーシング(11)の内部の前記エンジンと構成部品とを冷却する、ブロワ装置において、
前記ファン・ハウジング(24)もしくは送風管(14)内の空気流がブロックされた場合、空気が前記ファンから流出することが可能になるように、前記ファン・ハウジング(24)は、前記ファン・ハウジング(24)のどこかに設置された開口部(31)を設けられていることを特徴とする、
ブロワ装置。 - 通常使用の際に、前記開口部(31)を通って漏洩する空気の量が最小化されるように、前記開口部(31)は、前記ファン・ハウジング(24)の内部の圧力が低い、前記ファン・ハウジング(24)内の位置に設置されることを特徴とする、請求項1に記載のブロワ装置。
- 前記ファン・ハウジング(24)内の前記開口部(31)は、前記ファン・ホイール(21)の周縁に近接して設置されることを特徴とする、請求項2に記載のブロワ装置。
- 前記ファン・ハウジング(24)内の前記開口部(31)は、加熱された前記空気が、前記ケーシング(11)を抜け出ることが可能になるように、前記ケーシング内の出口開口部(19)の近くに設置されることを特徴とする、請求項1−3のいずれか一項に記載のブロワ装置。
- 前記開口部(31)の少なくとも一部分は、前記開口部(31)から前記ケーシング(11)内の前記出口開口部(19)に向かって、前記空気流を導入するガイド・カバー(32)により囲まれることを特徴とする、請求項4に記載のブロワ装置。
- 前記開口部(31)は、オペレータの背中に面している前記ファン・ハウジング(24)の側に設置されることを特徴とする、請求項3−5のいずれか一項に記載のブロワ装置。
