但纯水机工作期间，会产生大量的浓缩水，且是纯水的2～4倍，甚至更多。已经经过前置过滤过的浓缩水被当废水直接排入下水道，不仅增加了处理成本，也是一种对水资源的浪费，为了减少浓缩水的排放，现有技术中将反渗透净水器的浓缩水出水口，再接入反渗透膜膜前中，进行循环过滤，但这种方式很容易造成污堵，损伤反渗透膜，降低反渗透膜寿命，也有是在浓缩水出口处接上定时排放冲洗电磁阀或接上带有可以检测水体中溶解的固体浓度的TDS排放装置进行排放，但这种事先对排放做预先设定的排放，并不适应各地水质的差异，其实际效果并不理想。However, during the operation of the pure water machine, a large amount of concentrated water will be produced, which is 2 to 4 times that of pure water, or even more. The concentrated water that has been pre-filtered is directly discharged into the sewer as waste water, which not only increases the treatment cost, but also wastes water resources. In order to reduce the discharge of concentrated water, the reverse osmosis water purifier in the prior art The concentrated water outlet is connected to the front of the reverse osmosis membrane for circulating filtration, but this method is easy to cause fouling, damage the reverse osmosis membrane, and reduce the life of the reverse osmosis membrane. Discharge flushing solenoid valve or connect with a TDS discharge device that can detect the concentration of dissolved solids in the water for discharge, but this kind of discharge that is pre-set in advance does not adapt to the differences in water quality in various places, and its actual effect is not good. ideal.

本实用新型由于采用了以上技术方案，具有显著的技术效果：当使用纯水时，第二电磁阀、增压泵打开，第一电磁阀闭合，在连续制水中反渗透膜滤芯产生的浓缩水流入水箱中。当水满时，水箱中第一水位传感器动作，第一电磁阀打开，排放浓缩水。Due to the adoption of the above technical scheme, the utility model has remarkable technical effects: when pure water is used, the second electromagnetic valve and the booster pump are opened, the first electromagnetic valve is closed, and the concentrated water produced by the reverse osmosis membrane filter element in continuous water production into the tank. When the water is full, the first water level sensor in the water tank acts, the first electromagnetic valve opens, and the concentrated water is discharged.
当使用浓缩水时，第一压力开关动作，浓缩水从水箱流出，当水箱中储存的浓缩水快用完，若此时还需要使用浓缩水，水箱中第二水位传感器动作，这时进水第二电磁阀打开，水从反渗透膜前表面流过。When using concentrated water, the first pressure switch will act, and the concentrated water will flow out from the water tank. When the concentrated water stored in the water tank is almost used up, if the concentrated water needs to be used at this time, the second water level sensor in the water tank will act, and water will enter at this time. The second solenoid valve is opened, and water flows through the front surface of the reverse osmosis membrane.
