This article introduces the structure of the washing machine at the same time, and fully automatic washing machine control system for the very comprehensive analysis, and on the basis of fully automatic washing machine control scheme based on PLC is put forward, and the implementation plan, according to the washing machine working principle and application and its process of design, the system has a high intelligent degree, safe and reliable and stable operation, etc. Some of solenoid valves, buttons, switches and other input/output point to control, so as to realize the automation of the washing process, and many sets of control could be achieved. Because every time wash, drainage and dehydration time timer control by PLC, so just change the timer parameters can control time accordingly.
