Abstract
PURPOSE: To make blower with simple structure, cheap manufacturing cost, and high performance by combining main vane wheel and sub vane wheel to be joined at the root portion of respective vanes.
CONSTITUTION: Numeral 8a is the main blades cut and bent formed at a certain pitch to the inside of the cylindrical surface of the main blade body 6, and 7 is the body of sub vane which is cut and bent sub vane 8b on a rectangular plate at the same pitch with the main vane 8a as is shown in an exploded perspective view, and formed to a cylindrical form so that the inner diameter coincide with the outer diameter of the cylindrical portion of the main vane body 6. This sub vane body 7 is joined together with outer circumference of the main vane body 6 by way of e.g. with welding, etc., so that the end of the bented sub vane 8b coincide with the end of the bented maing vane 8a. This constitution allows to reduce number of parts, reduces manufacturing cost very much and enables to improve aero dynamical characteristics and reduce noise because of possibility of adopting twice so much of solidity and chamber angle.
