PROBLEM TO BE SOLVED: To increase miscibility of two kinds of air differing in property by a method other than mixing of the two kinds of air differing in property on a suction side of an air blower.SOLUTION: A scroll casing allowing a plurality of kinds of air blown out from a centrifugal multiblade fan rotating on an axis S of rotation comprises: an upper bottom wall 211 having an opening 21a formed to introduce hot air and cold air that the centrifugal multiblade fan sucks in; a lower bottom wall 212 opposed to the upper bottom wall 211; and an outer peripheral wall 210 connecting the walls 211, 212, a part 213b of an inner surface 213, on the side of the scroll space V, of the lower bottom wall 212 being formed not in parallel with the axis S of rotation so that the plurality of kinds of air blown out from the centrifugal multiblade fan flows in the scroll space V surrounded with the walls 210, 211 and 212 and more distant from the axis S of rotation than from the centrifugal multiblade fan, and a length of the scroll space V in a direction parallel with the axis S of rotation is longer with the distance from the axis S of rotation in the scroll space V.SELECTED DRAWING: Figure 4

    【課題】送風機の吸い込み側で性質の異なる2つの空気を混合させる以外の方法で、性質の異なる2つの空気の混合性を高める。【解決手段】回転軸Sの周りに回転する遠心多翼ファンから吹き出された複数種類の空気を流通させるスクロールケーシングは、遠心多翼ファンが吸い込む温風と冷風を導入するための開口部21aが形成された上側底壁211と、上側底壁211と対向する下側底壁212と、壁211、212を繋ぐ外周壁210とを備え、壁210、211、212によって囲まれると共に遠心多翼ファンよりも回転軸Sから離れたスクロール空間Vを、遠心多翼ファンから吹き出された複数種類の空気が流通し、スクロール空間Vの上記回転軸Sに平行な方向の長さが、スクロール空間Vにおいて、回転軸Sから離れるほど長くなるよう、下側底壁212のスクロール空間V側にある内面213の一部213bが回転軸Sに非平行に形成されている。【選択図】図4
