ABSTRACT:
A vehicle drying blower assembly includes a series of oscillating centrifugal fans each powered by a blower motor. Each centrifugal fan includes a circular fan rotated upon a driveshaft and surrounded by a housing having a discharge nozzle; the housing that surrounds the circular fan is supported by a rocker arm for pivotal movement about an axis of rotation coaxial with the circular fan driveshaft. The rocker arm pivots about a bearing assembly that lies coaxial with the driveshaft of the blower motor. A drive motor rotates an eccentric crank arm, and link rods coupled between the eccentric crank arm and the housing rocker arms simultaneously oscillate each centrifugal fan to blow moisture from the vehicle.
