BLOWER ASSEMBLY INCLUDING A NOISE ATTENUATING IMPELLER AND METHOD FOR ASSEMBLING THE SAME |
摘要 |
A blower assembly includes a housing including an outlet and a cutoff point positioned proximate the outlet. The blower assembly also includes an impeller including a plurality of blades that each includes a tip portion including a radially outer edge and a transition point that divides the radially outer edge into a first portion and a second portion. The impeller is positioned within the housing such that a first radial gap is defined between the cutoff point and the first portion and a second radial gap is defined between the cutoff point and the second portion. The first radial gap includes a constant width that is shorter than a width of the second radial gap. |
