Abstract:
A portable air blowing appliance has a housing retaining a blower adapted when energized to create an airflow through and from the housing, and a heating element adapted when energized to impart heat to the airflow. A movable deflector selectively steers the airflow either though or not through the heating element. In the exemplary embodiment shown, the blower is, in combination, a motor-driven centrifugal blower rotatable about a blower axis to create the airflow, and a scroll surrounding the blower wheel and adapted to direct the airflow from the blower wheel forwardly from the housing. In this exemplary embodiment, the deflector is movable about a pivot axis perpendicular to the blower axis between a heating position wherein the airflow is steered through the heating element and a cooling position where the airflow is steered not through the heating element.
