Abstract
A blower assembly having a housing and a cross flow fan rotatably mounted to the housing. Rotation of the fan drives fluid flow through the housing and produces an eccentric vortex of fluid flow in the housing. The fan has a circular blade support that induces fluid flow with rotation of the fan which interacts with the eccentric vortex. The circular blade support has at least one flow interrupter configured and arranged to rotate through the interaction of the eccentric vortex and the flow induced by the circular blade support to disrupt the interaction between the eccentric vortex and the flow induced by the circular blade support. In this manner, the at least one flow interrupter reduces the effect of the unstable vortex-blade support interaction on the airflow through the blower assembly which stabilizes the air loading on the blower assembly motor and reduces noise.
