Description

净水***、净水机及净水机控制方法Water purification system, water purifier and water purifier control method 技术领域technical field
本发明涉及净水装置技术领域，具体涉及一种净水***、净水机及净水机控制方法。The invention relates to the technical field of water purification devices, in particular to a water purification system, a water purifier and a water purifier control method.
背景技术Background technique
反渗透***是能够净化自来水，提供可饮用水的净水装置。随着人们对饮水要求的不断提高，反渗透***已经走入千家万户，保障家人的饮水安全。反渗透***的过滤核心是反渗透滤芯，其工作原理是原水经过增压泵提供压力，水分子透过反渗透膜形成纯水，无机盐离子、细菌、病毒、有机化合物和胶体等杂质被反渗透膜截留，通过废水排出。被截流在膜表面的杂质堆积在混合液侧，会和膜纯水侧形成浓度差，溶质会从高浓度向低浓度侧正渗透。A reverse osmosis water purifier is a water purification device that can purify tap water and provide drinking water. With the continuous improvement of people's requirements for drinking water, reverse osmosis water purifiers have entered thousands of households to ensure the safety of drinking water for families. The filtration core of the reverse osmosis water purifier is the reverse osmosis filter element. Its working principle is that the raw water is supplied with pressure by the booster pump, and the water molecules pass through the reverse osmosis membrane to form pure water, inorganic salt ions, bacteria, viruses, organic compounds and colloids and other impurities. Retained by reverse osmosis membrane and discharged through waste water. The impurities trapped on the membrane surface accumulate on the mixed liquid side, which will form a concentration difference with the pure water side of the membrane, and the solute will permeate from the high concentration to the low concentration side.
当反渗透***长时间不使用，混合液侧的无机盐离子和小分子会透过反渗透膜向纯水侧正渗透，导致纯水侧的TDS(Total dissolved solids，溶解性固体总量)升高。因此，***长时间停机用户开机制水时，接取的第一杯水TDS过高，不利饮用健康。When the reverse osmosis water purifier is not used for a long time, the inorganic salt ions and small molecules on the mixed liquid side will forward osmosis to the pure water side through the reverse osmosis membrane, resulting in TDS (Total dissolved solids, total dissolved solids) on the pure water side. ) rises. Therefore, when the water purifier is shut down for a long time and the user turns on the machine water, the TDS of the first cup of water received is too high, which is not conducive to drinking health.
此外，反渗透膜片一直浸泡在混合液侧，膜表面容易出现结垢，影响反渗透滤芯的性能和使用寿命。In addition, the reverse osmosis membrane has been immersed in the mixed liquid side, and the membrane surface is prone to scaling, which affects the performance and service life of the reverse osmosis filter element.

需要说明的是，检测到净水机开机，可为用户按动净水机的开机键，也可理解为用户启动净水机上的制水键，如“热水”键或“冷水”键等。从而使控制器控制三通过连接结构的第一通路开启，在一实施例中，当净水机内的三通连接结构为与泵体7的出水端相连通的泵端三通管9时，则在泵端三通管9的第一出水端与原水进口101之间的管道上还设置有第二进水电磁阀10，则检测到净水机开机时，控制器控制第二进水电磁阀10开启，控制第一进水电磁阀11和泵体7开启，控制废水电磁阀12、排水电磁阀13、抽水电磁阀14和进气电磁阀15关闭，以进行制水。It should be noted that when it is detected that the water purifier is turned on, the user can press the power-on button of the water purifier, and it can also be understood as the user starting the water-making button on the water purifier, such as the "hot water" button or "cold water" button, etc. . Thereby, the controller controls the opening of the first passage of the three-pass connecting structure. In one embodiment, when the three-way connecting structure in the water purifier is the pump-end three-way pipe 9 that communicates with the water outlet end of the pump body 7, Then a second water inlet solenoid valve 10 is also arranged on the pipe between the first water outlet end of the pump end tee pipe 9 and the raw water inlet 101, and when it is detected that the water purifier is turned on, the controller controls the second water inlet solenoid valve.

第二预设时长即抽取混合液的时长，第二预设时长可通过计量抽取出2/3-3/4的混合的时 长来控制，先将泵体7停止工作，从而可避免各管道内形成真空，以不利于下次制水。The second preset duration is the duration of extracting the mixed liquid. The second preset duration can be controlled by measuring the duration of 2/3-3/4 of the mixture. The pump body 7 is stopped first, so as to avoid the internal A vacuum is formed, which is not conducive to the next water production.
