摘要：【課題】送風機の入力低減と室外ユニットとしての騒音低減を図る。【解決手段】羽根車と、羽根車の羽根の吐出側の外周を囲うオリフィス8から成り、オリフィスの吐出側8bは吐出方向に向かって次第に広がる吹出口9を有し、前記羽根車の羽根7の吐出側の外周端部の略半径方向外側で、上記オリフィス8の吐出側の内壁8b1から離れた位置にリング状の板10を配置した構成としてある。これにより、羽根車から吹出され最も流速が早くなる羽根外周側のオリフィス内壁近傍の流れが、スムーズに減速しつつ流れる。よって、羽根外周側の動圧が静圧に損失を抑えながら効率よく変換されて広がり、送風機としての空力性能とファン効率が向上し、送風機の入力低減と室外ユニットとしての騒音低減を図ることができる。【選択図】図2
摘要翻译：要解决的问题：实现鼓风机的输入降低和室外机的降噪。解决方案：一种鼓风机，包括叶轮和围绕叶轮的叶片的排出侧外周的孔8，在排气侧的排气侧8b设置排出口9，排出口9逐渐扩散，并且环状板10配置在远离喷嘴的喷出侧内壁8b1的位置，叶轮的叶片7的外周端部。因此，空气从叶轮吹出并以最高流速流动的叶片外周侧的孔内壁附近的空气流速平缓地降低。因此，叶片外周侧的动态压力有效地转化为静压，同时其损失抑制扩大，并且提高了鼓风机的空气动力性能和风扇效率，从而实现鼓风机的输入减少和降低噪音一个室外机。
