The article during introduction washer structure, carries on the analysis to the completely automatic washer control system, proposed in this foundation based on the PLC completely automatic washer control plan, and has carried on the proof to the plan, has carried on the design according to the washer principle of work to the procedure and the flow, has the intellectualized degree high, safe reliable and so on the characteristics. To the button, the relay, the switch, the frequency changer and so on other some I/O spot carries on the control, realized the washer to wash clothes the process automation. Because spreads every time lavation, draining water, dehydrated time by PLC in counter control, so long as therefore the change counter parameter may change the time. span class=Thc990/span br / PLC is takes core to control devised the calculator technique as the in general use automation control equip to c
