    摘要： A blower includes: an impeller on which there are arranged axial flow blades 40 mounted at circumferential intervals to an outer peripheral surface of a boss; a case surrounding the impeller; and a bell mouth cylindrically constricted to guide gas into the case, wherein an inner diameter of the bell mouth is smaller than an outer diameter of the impeller. Further, each blade has, in the radial direction, a sweepforward wing portion situated on the boss side and exhibiting a positive advance ratio value, and a sweepback wing portion situated on the outer peripheral side of the blade and exhibiting a negative advance ratio value, with the arc length of each blade increasing from the boss side toward the outer peripheral side. Therefore, it is possible to achieve an improvement in ventilation efficiently, through an increase in static pressure and to achieve a reduction in noise.

    摘要： A blowing apparatus includes a suction passage having a suction chamber enclosed by rigid body surfaces, suction ports opening toward the suction chamber for sucking air from outside, and a fan suction port serving as a suction port for a blower, the suction ports, the suction chamber, and the fan suction port being arranged in nonlinear form. In such blowing apparatus, a doughnut-like straightening guide is arranged on an opening edge on the suction chamber side of the fan suction port. The straightening guide has a projection toward the suction chamber, an appropriate thickness in the radial direction, and a guide passage matching the fan suction port in the middle thereof.
