Abstract: The square washing area in dishwashers with round coverage formed by common spray results in always insufficient washing at the four corners. Based on intensive study and analysis several specific mathematical curves, there proposes a variety of spray running track solutions with specific transmission mechanism design which can achieve high-coverage even full-coverage for square area. Furthermore, the generation theory and approving result are introduced and discussed in detail, thus having good guidance for innovative design of the dishwasher sprays.
