Abstract
PURPOSE: To shorten an overall length of a fan in the blower and decrease a mounting space of the fan, by forming a sloped surface on the periphery of an iron ring constructed as an integral unit with the fan in such a manner as to be profiled along the cross sectional pattern of a cylindrical part of the fan.
CONSTITUTION: At the inner circumferential side of a blade 15 of a fan 14, is provided a cylindrical portion 17b having a tapered cross section of thin thickness at its suction side. An iron ring 16 is embedded to the cylindrical portion 17b as a rotor. At inner circumferential sides of the iron ring 16, a stator 19 is arranged. In this way, the fan 14 can be rotated independently of a rotary motion of the main motor 1. The peripheral surface of the iron ring 16 is constructed into a sloped face 16a in such a manner that the fan comes to be in a thin thickness at its suction side profiling along a thickness of the cylindrical portion. In this way, the area of a suction port of the fan can be widened and the length can be axially shortened.
