In recent years, fuzzy control make wide application in the appliance, washing machine with fuzzy control has many abilities such as automatic recognizing the kind of clothes, mount of clothes, dirt condition, automatic controlling the mount of water, automatic determining the mount of detergent. Not only it accomplishes overall automation of wash machine, but also greatly enhances washing quality and has powerfully practical ability and bright prospect. Based on fuzzy control, completely automatic washing machine control system has AT89C51single chip computer as a core, can realize intelligent control to save energy and enhance quality. The hardware diagram and software flow chart are important part of the system. The fuzzy control software play a decisive role in the whole control process. Based on 51 serial single chip computer, control system of washing machine consists of a control panel which includes the pressing keys, displaying lamps and LED device. The pressing keys select washin
