自动晾衣架设计
摘要：晾衣架最简单的一种是一根竹竿固定或悬挂在屋顶板下、窗外等地方；现在的居民很多是在天花板下焊接一根铁管作为晾衣架的挂具，晾衣服时，必须将衣服一件一件地穿上衣架，再用杈子将衣服挂在铁管上，工作效率低，又不方便，时常将衣服掉地弄脏，而且还不能充分利用阳光。而目前市场上所卖的自动晾衣架只能满足单一的升降或单一的收缩功能，但升降功能只能解决挂衣服费力的问题却不能很好的利用阳光资源，而收缩功能刚好相反，只能解决充分利用阳光资源但不能解决费力这个问题。

Automatic clothes hanger design
Abstract: the clothes hanger, the simplest is a bamboo pole fixed or hung on the roof plate, out of the window and other places; now many residents in the ceiling is welded with a pipe as hanging clothes hanger, clothes, must take the clothes to wear clothes rack, and then branched sub clothes hanging in the pipe, the working efficiency is low, and inconvenient, often will fall to dirty clothes, but also can not make full use of the sun. Currently on the market and sell automatic clothes hanger can only satisfy the single lifting or contraction of single function, but the function of lifting can only solve the hanging clothes laborious problem but sunshine resources can not be used, while the systolic function is just the opposite, can only solve the full use of sunlight resources but can not solve the problem of labor.
