BLOWER AND WASHING MACHINE EQUIPPED WITH THE SAME

To provide a blower capable of achieving both downsizing and high efficiency.SOLUTION: A blower has a rotary shaft 101 rotatably provided on an electric motor 100, a centrifugal impeller 300 that is provided on the rotary shaft 101, a diffuser channel 410 that is provided on the downstream side of the centrifugal impeller 300, and is composed of a plurality of diffuser vanes 401 disposed in a circumferential direction, a diffuser 400 that is equipped with a diffuser channel 410, a scroll channel 70 that is provided on the outer side in a diametrical direction of the centrifugal impeller 300 of the diffuser channel 410, and a fan casing 52 that is fixed to the diffuser 400. The fan casing 52 has a plurality of screw holes 93 in which screws fixing the diffuser 400 is inserted in a circumferential direction between the rotary shaft 101 and the scroll channel 70, and distances between the screw holes 93 and the rotary shaft 101 are different from each other.SELECTED DRAWING: Figure 3 【課題】小型化と高効率化の両立が可能な送風機を提供する。【解決手段】電動機１００に回転自在に設けられる回転軸１０１と、回転軸１０１に設けられる遠心羽根車３００と、遠心羽根車３００の下流に設けられ、周方向に配置された複数のディフューザベーン４０１によって構成されるディフューザ流路４１０と、ディフューザ流路４１０を備えたディフューザ４００と、ディフューザ流路４１０の遠心羽根車３００の径方向外側に設けられたスクロール流路７０と、ディフューザ４００と固定されるファンケーシング５２と、を有し、ファンケーシング５２は、回転軸１０１とスクロール流路７０の間の周方向にディフューザ４００を固定するねじが入るねじ穴９３)を複数有し、それぞれのねじ穴９３と回転軸１０１との距離が、それぞれ異なる、構成とする。【選択図】 図３
