ABSTRACT:
A blower assembly includes a motor cover having (1) a body portion defining a motor cavity, (2) an air flow guide surface connected to an end of the body portion, the guide surface extending radially outwardly from the body portion, and (3) a cooling duct integrally formed with the body portion and having an inlet and an outlet, the inlet being located at the end of the body portion and the outlet being defined in a sidewall of the body portion. The blower assembly further includes a motor positionable in the motor cavity, the motor having a motor shaft having a central axis. In addition, the blower assembly includes a fan housing is connected to the motor cover, wherein (1) the fan housing defines a scroll cut-off line, and (2) a plane passes through the scroll cut-off line and the central axis, and (3) the cooling duct is positioned adjacent to the plane. The blower assembly also includes a fan positioned within the fan housing, wherein (1) the fan rotates in a rotational direction, and (2) the cooling duct is positioned on the upstream side of the plane relative to the rotational direction of the fan.
