| description | PROBLEM TO BE SOLVED: To provide a centrifugal fan improving an amount of air through shape of a rotating vane.SOLUTION: A centrifugal fan 50 of this invention has rotary vanes 60 provided with an inner blade region 62b inside an outer blade region 62a, a side part 64a of the inner blade region 62b at a suction port side is faced toward a peripheral edge to form a concave radius shape to enable an amount of air under its rotation to be increased. With this arrangement as above, saving of electrical power at ventilation facility can be attained. In addition, it is possible to make a small-sized centrifugal fan 50 in correspondence with an increased amount of air. Further, the centrifugal fan 50 of this invention causes an engaging part 52 to be protruded out of a main plate 54 and at the same time causes inner peripheral ends 64c of the rotary vanes 60 to be positioned at the main plate 54 rather than the engaging part 52, arrangement of clearances around the engaging part 52 enables an amount of air at the centrifugal fan 50 to be increased more.SELECTED DRAWING: Figure 2
【課題】回転羽根の形状により風量の向上を図った遠心ファンを提供する【解決手段】この遠心ファン５０は、外翼領域６２ａの内側に内翼領域６２ｂを備えた回転羽根６０を有し、さらに内翼領域６２ｂの吸気口側の側辺６４ａを周縁側に向けて凹状のアールとすることで回転時の風量を増大させることができる。これにより、換気設備の省電力化を図ることができる。また、風量の増大分、遠心ファン５０の小型化を図ることができる。さらに、本発明に係る遠心ファン５０は、係合部５２を主板５４から突出させるとともに、回転羽根６０の内周端６４ｃを係合部５２よりも主板５４側に位置させ、係合部５２の周囲に空隙を設けることで遠心ファン５０の風量をさらに増大させることができる。【選択図】図２ |
