1、FPGA课程设计报告项目名称电风扇的自动定时开关控制专业班级学生姓名指导教师2013年6月4日33摘要如今的电风扇已一改人们印象中的传统形象,在外观和功能上都更追求个性化,而电脑控制、自然风、睡眠风、负离子功能等这些本属于空调器的功能,也被众多的电风扇厂家采用,并增加了照明、驱蚊等更多的实用功能。这些外观不拘一格并且功能多样的产品,预示了整个电风扇行业的发展趋势。在追求个性时尚以及精致化的时代,消费者似乎对娇小可爱的家电产品情有独钟,于是扮相可爱、颜色亮丽、体积娇小的转页扇,各种便携式电风扇应运而生。这些电风扇的外壳和扇页都以塑料为原料,整体上极其轻巧,加上娇小的体积和靓丽的色彩和外观,
2、一经推出便十分走俏。电风扇增设了各种新功能,既彰显了个性,也在无形中提高了档次。如开发较早且比较实用的遥控功能,使操作摆脱了一定的空间限制,再加上液晶屏幕的动态显示,操作起来一目了然。随着消费者对健康的日益关注,厂家围绕着提高空气质量做起了文章,于是便增添了负离子、氧吧、紫外线杀菌等功能。此外,驱蚊风扇可通过电加热使驱蚊物质挥发,并借助风力快速把驱蚊物质送到房间各个地方;带有“飘香”功能的小风扇在扇片中间的旋转轴内含有香片,随着扇片的转动,悠悠花香也随之飘出,并且香片可随意更换;带有照明功能的吊扇集照明与风扇功能于一体,他们都是凭借了某一项独特的功能而吸引了消费者的目光。关键词:电脑控制
