摘要

藉傳統的水洗機的運轉模式為布動水不動，織物的退漿效果不好，本研究開發離心噴流機構，在布動水也動的互動情形下，可增加織物的退漿效果，在機構優化設計上，首先考量離心噴流機構的幾何形狀設計，噴流筒傳動軸心採用中空方式由泵浦抽水入離心噴流筒，可依據不同織物需要的水流大小來調整入水量，配合傳動軸的轉速及機械振頻等，形成離心噴流水洗技術。接著利用單一離心噴流組件設計幾何多邊形變化與控制參數分析，透過系統建模及模擬分析，使用ANSYS fluent分析軟體得到機構設計的最佳參數。最後則依據模擬之結果進行離心噴流機構實作及效益驗證。其模擬結果筒身形狀以八邊型為最優，經由機構製造後，在機台測試上，利用轉速計測量噴流筒馬達之轉速，測試機台性能精確度，噴流筒轉速設定值與實際轉速值百分比誤差＜1%。

The operation mode of the traditional washing machine is that the water keep stationary move, and the desizing effect of the fabric is not good enough. This research develops a centrifugal jet mechanism, which can increase the desizing effect of the fabric under the interaction of the moving water, and optimize the mechanism. The geometry design of the centrifugal jet mechanism is first considered. The water is injected into the hollow shaft of centrifugal jet tube by jet pupm. The new centrifugal jet water wasing technique was formed when water flow can be adjusted with different fabrics, shaft speed, mechanical speed and vibration frequency. of the mechanical Then, the geometrical polygon change and control parameter analysis are designed by using a single centrifugal jet flow component. Through the system modeling and simulation analysis, the optimal parameters of the mechanism design are obtained by using ANSYS fluent analysis software. Finally, based on the results of the simulation, the centrifugal spray mechanism is implemented and the benefit is verified. The simulation results show that the shape of the jet tube is optimized by the octagonal type. After the mechanism is manufactured, the speed of the jet motor is measured by the tachometer on the machine the percentage error in performance precision of the test machine, the jet speed and the actual speed is less than 1%.
