Abstract
PURPOSE: To provide a conical disk ring opening backwards adjacent the rear side of blade such that an impeller by itself blows in the manner of a cone with wide vertical angle.
CONSTITUTION: A propeller fan 2 is provided on the rear edge 4b of blade 4 with a conical disk ring 5 opening backwards. Thus the radial differential pressure by aid of th action of centrifugal fan is balanced with the axail differential pressure so that air flow is slanted. Also in this case, since air flow d sucked from the central portion is interposed between the disk ring 5 and air C sucked from the outer periphery, the contact of air C with the disk ring 5 reduced so that the air C is discharged obliquely with small loss and high efficiency. Also the disk ring 5 acts to bias air to the central portion of the blow side and flow it from the inner diameter side F of the disk ring 5 to the blade side 4 so that said flow d is biased to the radial side to provide a fluid element blowing at wide angle.
