要
在目前各种智能电风扇的前提下，我们加入了电风扇制热这项功能。我们主 要采用石英管发热原理来进行导热，达到在冬季使用电风扇来取暖的目的。应用 单片机原理来控制电风扇各项指令，采用拨式摇头装置来进行摇头，而且还能执 行电风扇的无极调速。 关键词：制热、石英管发热原理、单片机、无极调速
In the current under the premise of all kinds of intelligent electric fans, we joined the fan heating this feature. We mainly adopts quartz tube heating principle to heat conduction, achieve the purpose of using the electric fan to keep them warm in winter. Each instruction principle of application of single chip microcomputer to control the electric fan, using dial type shook his head, shaking his head device and also can perform infinitely adjustable-speed electric fans. Keywords: heating, quartz tube heating principle, single-chip microcomputer, the infinite speed
