Abstract
With the continuous progress of science and technology and the rapid development
of society, washing into people's everyday life, household products.
Fully automatic washing machines, multi-functional and intelligent direction of its
development. This paper describes the development of washing machines, washing
machine and then focuses on the design and programming software, the program
flow chart are described, and finally the system is simulated. The design uses a step
sequence programming instructions, according to process requirements of simple
programming, which allows dual coils, PLC sampling buttons and limit switch
changes the external input signal, perform the appropriate procedure, and then
reversing the motor output control and dehydration treatment.
Finally on the subject summarized the work done, and further research put forward
their views. The design of the automatic washing process requirements need to be
improved, not a separate set of time dehydration and laundry; Due to time
constraints, no further improvement. Automatic washing machine based on widely
used in daily life, the design of a wide range of promotional value.
