    • 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.
    • 便携式吹风器具具有外壳,该外壳保持鼓风机,该鼓风机在通电时适应于产生通过和从外壳的气流;以及加热元件,其适于在通电时向气流赋予热量。 可移动偏转器选择性地引导气流或者通过加热元件。 在所示的示例性实施例中,鼓风机是组合地围绕鼓风机轴线旋转以产生气流的电动离心鼓风机和围绕鼓风机叶轮的涡卷,并且适于将来自鼓风机叶轮的气流从壳体 。 在该示例性实施例中,偏转器可以在气流被引导通过加热元件的加热位置和不通过加热元件转向气流的冷却位置之间围绕垂直于鼓风机轴线的枢转轴线移动。
