    • A portable fan heater wherein the housing has a front opening in register with a ceramic panel which transmits infrared radiation. The panel is located in front of one or more halogen lamps, such as quartz lamps, whose radiation is directed toward the panel by a reflector having a concave side facing the lamp or lamps and having its center of curvature in or close to the panel. One lamp (or the single lamp) is located at the focal point of the reflector. The housing contains a rotary fan which is driven by an electric motor and serves to convey currents of air from several inlets in the rear wall of the housing toward and into the opening. The currents flow through constricted channels which are defined by the outer side of the reflector and the adjacent inwardly convexly curved walls of the housing.
    • 一种便携式风扇加热器,其中壳体具有与透射红外辐射的陶瓷面板对准的前开口。 面板位于一个或多个卤素灯的前面,例如石英灯,其辐射通过具有面向灯或灯的凹面的反射器朝向面板,并且其曲率中心在面板中或靠近面板。 一个灯(或单个灯)位于反射器的焦点处。 壳体包含由电动机驱动的旋转风扇,用于将空气的流动从壳体的后壁中的多个入口传送到开口中。 电流流过由反射器的外侧和壳体的相邻的向内凸出的弯曲壁限定的收缩通道。
