Vortex flow blower and vane wheel therefor

Abstract

A vane wheel driven by a shaft for transferring a gas, comprises, vortex flow chambers opening in a direction substantially parallel to the shaft to receive the gas, to urge the gas in a substantially circumferential direction of the vane wheel, and to generate and accelerate a vortex flow of the gas, A vane member includes a hub through which the vane member is connected to the shaft, with the vane member including a plurality of vanes each extending integrally from the hub in a substantially radial direction of the vane wheel. Each of the vanes includes a front surface for urging the gas in the substantially circumferential direction of the vane wheel. A vortex flow chamber wall extends integrally from both the hub and each of the vanes, and a cover contacts the vortex flow chamber wall to form the vortex flow chambers together with the vortex flow chamber wall and the vanes.
