Abstract: The using of ultrasonic technology make the development of dishwasher more diversified. This paper has improved and redesigned the overall structure of the dishwasher, the cleaning process and control system. The structure: the cleaning tank is made of stainless steel. The dishwasher consists of reasonable layout of the ultrasonic system, the spray arm flush device and the plumbing system, so that the structure is more compact and reasonable, to improve the cleaning effect. Cleaning process: figuring out the distribution of ultrasonic cavitations’ intensity and selecting appropriate parameters to determine the optimal cleaning process.
Key words: ultrasonic; dishwasher; the design of overall structure ;
