Abstract:
(EN) A centrifugal blower is provided with: an impeller (2) rotationally driven by a drive motor (3); a scroll casing (4) provided with a suction opening surface (10) having an opening (9), the scroll casing (4) being further provided with a wall (12), the distance of which from an axis serving as the rotation center of the impeller (2) varies depending on the position of the wall (12), the scroll casing (4) redirecting the air flow in the centrifugal direction, which is generated by the rotation of the impeller (2), to one direction; an air intake section (13) provided with a bell mouth section (18) having a large-diameter-side end (16) located further toward the upstream side of the flow of sucked-in air than the suction opening surface (10); and a protrusion section (15) extending from the air intake section (13) in the direction perpendicular to the axis as the rotation center of the impeller (2) and away from the rotation center and surrounding a part of the bell mouth section (18).
(FR) Soufflante centrifuge pourvue : d'une roue (2) entraînée en rotation par un moteur d'entraînement (3); d'un carter en spirale (4) pourvu d'une surface d'ouverture d'aspiration (10) ayant une ouverture (9), le carter en spirale (4) étant en outre pourvu d'une paroi (12), dont la distance par rapport à un axe servant de centre de rotation de la roue (2) varie en fonction de la position de la paroi (12), le carter en spirale (4) redirigeant l'écoulement d'air dans la direction centrifuge, qui est produit par la rotation de la roue (2), dans une première direction; d'une section d'admission d'air (13) pourvue d'une section pavillon (18) ayant une extrémité côté grand diamètre (16) située plus vers le côté amont de l'écoulement d'air aspiré que la surface d'ouverture d'aspiration (10); et d'une section saillie (15) s'étendant depuis la section d'admission d'air (13) dans la direction perpendiculaire à l'axe servant de centre de rotation de la roue (2) et loin du centre de rotation et entourant une partie de la section pavillon (18).
(JA) 駆動モータ(3)によって回転駆動される羽根車(2)と、開口(9)を有する吸込口面(10)と、羽根車(2)の回転中心となる軸線からの距離が、場所によって異なる壁部(12)とを備え、羽根車(2)の回転によって発生した遠心方向の気流を一方向の気流に変換するスクロールケーシング(4)と、吸込口面(10)よりも吸込空気の流れの上流側に大径側端(16)が配置されたベルマウス部(18)を備えた空気取り込み部(13)と、空気取り込み部(13)から、羽根車(2)の回転中心となる軸線に直交する方向かつ回転中心から遠ざかる方向に延在し、ベルマウス部(18)の一部分を囲む突出部(15)を有する。
