就一般家庭用水而言,衛浴用水佔了很大的比例;由經濟部水利署的資料顯示,衛浴設備(主要指馬桶)佔了家庭用水量的比例,高達40﹪~50﹪。若能減少傳統沖水馬桶用水,對節約民生用水,將有顯著的助益。本次研究目的是源自於本校與德晃公司之產學合作計劃,其宗旨是嘗試利用噴射泵的概念來產生壓力差,在產生初步之抽吸後再依虹吸原理吸除馬桶內剩餘穢物,以達到省水的目的。過程中藉由流電腦軟體FloWorks模擬並改良設計,加上實際製作模型以驗證成果。本研究所獲致之重要結論如以下:
(1) 確認噴射泵系統運用於馬桶沖水系統的可行性。
(2) 就省水的效益而言,噴射泵系統優於現有的任何系統,主要是因為不需藉由注水使馬桶內的水位上升後,才經虹吸作用產生吸力,而是直接藉由噴嘴噴出之高速流體在流道內產生吸力,故可以有較好之省水的效果。
(3) 由實驗中發現,噴嘴安裝的位置,與馬桶本體底部流道的形狀,對噴射泵系統性能有很大的影響;若二者搭配不當,會使噴射泵系統吸力降低,或在馬桶本體底部產生吸力死角,都會造成噴射泵系統整體性能的損失。
(4) 在噴射泵系統的設計上,未考慮是否能通過國家標準CNS3221衛生陶瓷器檢驗法的測試,以致於因排水口的尺寸選擇不當,使得流道整體太過狹窄,在做馬桶洗淨試驗時無法通過測試。
According to the data issued by the Water Resources Agency, Ministry of Economic Affairs, it shows that toilet flushing takes about 40% to 50% of the total household water consumption. Therefore, it will be very beneficial to water saving if the amount used for traditional toilet flushing can be reduced.

The research idea was originated from a cooperated project with the Welter’s company. The purpose is to implement the working concept of the jet pump into the design of a water closet and achieves the objective of water saving. The pressure difference that is required to initiate the sucking action is produced by a water jet. It then is followed by the siphon effect to remove the remaining of the dirty staff left in the toilet. In the research process, FloWorks was used to simulate the flow field and helped to evaluate and modify the model design, and prototype was built and tested to verify its function. The following conclusions can be reached based on the results:

1. The idea of implementing the working concept of a jet pump into the design of a water closet was proved feasible.
2. In terms of the water saving capability, the new design is indeed better than those traditional systems. Instead of inducing the siphon effect through filling water to a certain height, the new design provides similar action with extra suction force through the injection of a high speed jet.
3. The installation position for the injection nozzle and the shape of the flow passage at the bottom of the water closet are important factors that will affect new design’s performance.
4. Due to the improper size selection of the drainpipe, the new design was unable to pass the CNS3221 standard test, which will require further modification.
