7、按鈕,电磁阀,开关等其他一些输入/输出点进行控制,实现了洗衣机洗衣过程的自动化。由于每遍的洗涤,排水,脱水的时间由PLC内计数器控制,所以只要改变计数器参数就可以改变时间。可以把上面设定的程序时间定下来,作为固定程序使用,也可以根据衣物的质地,数量及油污的程度来编程。只要稍作改变,就可以设计出诸如要多洗多甩的牛仔类衣物,轻洗轻甩的羊毛类衣物以及通用的标准洗涤程序,充分表现现代家电品的实用性。在洗衣机控制方面，在PLC问世之前，工业控制领域中是继电器占主导地位。但继电器控制领域有着十分明显的缺点：体
8、积大、耗电多、可靠性、寿命短、运行速度慢、适应性差、尤其当生产工艺发生变化时，就必须重新设计、重新安装，造成时间和资金的严重浪费。为了改变这一现状，PLC控制系统产生了。继1969年美国数字设备公司研制出世界第一台PLC，并在通用汽车公司自动装配线上试用，获得了成功，从而开创了工业控制新时期，从此，可编程控制器这一新的控制技术迅速发展起来了。在许多领域都有广泛的应用。PLC的优点是：可靠性高，耗电少，适应性强，运行速度快，寿命长等，为了进一步提高全自动洗衣机的功能和性能，避免传统控
