Abstract: Adding efficient clean for the filtration system in dishwashers during the washing process aims to reduce the trouble for users to disassemble and clean the filtration system. The self-cleaning technology for the filtration system is certainly the demand and expectation of consumers, and the corresponding implementation solution has become a pressing issue that needs to be addressed in the dishwasher industry at this stage. Based on the development of self-cleaning technology for the filtration system, here construct different designs of the cleaning ring component, then through the simulation analysis and comparison, the evaluations about advantages and disadvantages of different designs can be gotten and then the design can be optimized accordingly. Furthermore, it conducted comparative experimental tests to analyze and verify what the influence of different cleaning ring component designs for the cleaning performance of dishwasher is. Finally, the effectiveness of the optimization design is confirmed, leading to achieve the optimization and improvement of the self-cleaning technology for the filtration system.
