The invention provides an automatic water changing system, which mainly comprises: a water storage bucket, a pump, at least one sterilization device, a control device, a first water tank and a second water tank. In particular, the water in the water storage tank may be injected into the first water tank after being sterilized by the sterilization device by the control of the control device. In addition, the operator can also set the soaking time of each dialysis treatment through the control device. After the immersion dialysis for a predetermined period of time is completed, the control device controls the pump to transfer the water in the first water tank to the second water tank (ie, change the water tank). Obviously, the automatic water changing system of the present invention can automatically repeat the actions of water injection-soaking dialysis-drainage, etc., which can improve the defects of the automatic immersion water tank used in the existing dialysis treatment.本新型提出一種自動換水系統，係主要包括：一儲水桶、一幫浦、至少一殺菌裝置、一控制裝置、一第一水槽、一第二水槽。特別地，透過該控制裝置之控制，儲水桶內的水可先經過該殺菌裝置的殺菌處理之後而注入第一水槽。此外，操作人員亦可透過控制裝置設定每一次透析處理的浸泡時間。完成預定時間的浸泡透析後，控制裝置便控制幫浦將第一水槽內的水轉送至第二水槽(亦即，換水槽)。顯然地，本新型之自動換水系統可以自動地重複注水-浸泡透析-排水等動作，係能夠改善現有的透析處理所使用的浸泡水槽缺乏自動換水功能之缺陷。
