Abstract
A draft inducer blower for high efficiency furnaces, including a blower housing which provides enhanced contact between the blower housing and the furnace collector box to reduce the flexing and vibration between the blower housing and the collector box. The blower housing includes contact structure which provides a direct abutting contact relationship between the blower housing and the collector box at least along a substantial periphery of the blower housing and/or at one or more rigid transition points on the collector box. In one embodiment, the contact structure can be part of the blower housing body and/or the blower housing cover. In another embodiment, the contact structure can be part of the collector box or furnace to which the blower housing is mounted. When fasteners secure the blower housing to the collector box, the contact structure provides a substantially integral rigid construct between the blower housing and the collector box.
