Abstract
PURPOSE:To improve the extent of fan efficiency as well as to aim at the promotion of low noise by setting a winding angle in a scroll casing down to a specified large angle, while expanding axial scroll width at the discharge side gradually from a specified position. CONSTITUTION:A centrifugal blower has each multiblade fan 3 in a logarithmic spiral-form suction side scroll casing 1 and a discharge side scroll casing 2, and discharges air, inhaled from a suction port 11, out of a discharge port 21. In this case, a winding angle (an angle in a fan rotational direction from a point B to a point C) thetas of the scroll casing 1 should be set to 300 or 330 deg.. And, at the discharge side of this casing 1, scroll width W in the axial direction along a direction of rotation of the multiblade fan 3 from a position (position of thetao) at 60 or 180 deg. in front of a tongue part 5 is made so as to be gradually expanded.
