Technical Examples

A draft inducer blower for high efficiency furnaces, including a blower housing which facilitates maximum air flow efficiency through the blower housing while reducing air flow noises. The blower housing generally includes a housing body and housing cover which define an exhaust transition therebetween, which transitions the air flow from the circular main cavity of the blower housing to the blower housing outlet. The housing body and housing cover are attached to one another via a lobed joint along the exhaust transition, and each include complementary, smoothly contoured inner surfaces to facilitate smooth air flow through the exhaust transition toward the outlet. Additionally, the housing body and housing cover include cooperating cutoff surfaces which form a broadly radiused cutoff within the blower housing to reduce or eliminate the blade pass noise associated with contact of the air flow from the impeller with the cutoff.
