Abstract:
An appliance provides a platform having a platform bottom and a platform base which supports a main base. A motor is carried by the platform base and rotates a ventilation fan which has a plurality of radial vanes with a fan aperture centrally positioned therein, such that the ventilation fan draws air in through an intake port provided by the platform. A fan shroud encloses the ventilation fan and has a shroud opening. The fan shroud extends from the platform base toward the platform bottom, wherein the main base surrounds the motor. The main base has an outer housing with at least one housing port, wherein rotation of the ventilation fan draws air into the fan aperture from the intake port, through the shroud opening, and expels the air radially from the plurality of radial vanes so that the air flows through the motor and out the housing port.
