| The roller washing machine is developed in two directions. One direction is the wash technology innovation, such as steam wash, ultrasonic wash, health and sterilization, silver ions, the other direction is the control technology.First of all, through the analysis of custom’s specifications, the overall control system was determined. Based on the principle of roller washing machine, the wash beats were optimized. Through the analysis of fuzzy control, clothing weight functions were established, such as:nephelometric function, water temperature function, main wash function as well as heater temperature function. And then instead of the user, the machine could set the washing time, wash temperature, rinse times by itself. Besides intelligent methods, a few useful functions are adopted, such as power failure memory, child lock and turn off automatically.Second, based on the principle of NEC78F0513, the circuit boards were designed, including the interface circuit, power supply circuit, the control circuit of the valve, the water level detection circuit and reset circuit. In the process of software design, process control technology-WashTable control technology is introduced into the washing process control. Follow the software design process, the program of water plus, the program of drainage, the program of washing and rinsing were designed, the program of dehydration and the program of complete washing process also were designed.Finally, based on the above hardware and software systems, the sample was made, using the Complog program, the system was tested on prototype machine. Contrasted with normal washing machine, the new intelligent control washing machine can reach23%water-saving and5.2%electricity saving, and also reached the cleanlily standard. |
