Description
技术领域Technical Field
本实用新型涉及净水器技术领域，尤其涉及一种可降低首杯水TDS值的净水器。The utility model relates to the technical field of water purifiers, in particular to a water purifier capable of reducing the TDS value of a first cup of water.
背景技术Background Art
反渗透净水机是一种利用反渗透技术来过滤和净化水源的设备，它通过高压驱动水分子穿过半透膜，将水中的杂质、重金属、细菌和病毒等有害物质过滤掉，从而得到清澈透明的纯净水，这种净水机能够有效去除水中的有害物质，提供安全健康的饮用水，是家庭和商业场所常用的水处理设备之一。A reverse osmosis water purifier is a device that uses reverse osmosis technology to filter and purify water. It drives water molecules through a semi-permeable membrane at high pressure to filter out harmful substances such as impurities, heavy metals, bacteria and viruses in the water, thereby obtaining clear and transparent pure water. This water purifier can effectively remove harmful substances in the water and provide safe and healthy drinking water. It is one of the commonly used water treatment equipment in homes and commercial places.
但是，现有的一些传统的反渗透净水机在净水机停机静止时，反渗透膜会长期处于浓水浸泡中，导致反渗透膜原水侧的水向纯水侧的水渗透，纯水侧的水TDS值就会接近反渗透膜原水侧的水TDS值，当反渗透净水机再启动制水后，其初始制取的纯水TDS值会大幅超出标准值；其次，由于反渗透膜长期浸泡在浓水中，膜片表面极易结构导致反渗透膜的使用寿命大幅降低，目前，有反渗透净水机增加了纯水泡膜功能，但为了实现此功能，往往需要通过压力罐或纯水箱加水泵的方式将纯水输送到RO膜前，这样的话就同时需要增加很多管路和阀进行水路切换，不仅增加了水路复杂程度，还增加漏水风险，同时成本也大幅增加。However, when some existing traditional reverse osmosis water purifiers are shut down, the reverse osmosis membrane will be immersed in concentrated water for a long time, causing the water on the raw water side of the reverse osmosis membrane to penetrate into the water on the pure water side. The TDS value of the water on the pure water side will be close to the TDS value of the water on the raw water side of the reverse osmosis membrane. When the reverse osmosis water purifier is started to produce water again, the initial TDS value of the pure water produced will greatly exceed the standard value; secondly, since the reverse osmosis membrane is immersed in concentrated water for a long time, the surface of the membrane is very easy to structure, resulting in a significant reduction in the service life of the reverse osmosis membrane. At present, some reverse osmosis water purifiers have added a pure water bubble membrane function, but in order to achieve this function, it is often necessary to transport pure water to the front of the RO membrane through a pressure tank or a pure water tank plus a water pump. In this case, it is necessary to add a lot of pipes and valves for water circuit switching, which not only increases the complexity of the water circuit, but also increases the risk of water leakage, and the cost is also greatly increased.

The TDS probe 13 is arranged on one side of the water pipe close to the RO membrane filter element 4, and the flow meter 14 is arranged on the TDS probe 13 close to the pure water. On one side of the tank 5, the pure water tank 5 includes an outer shell, and a water inlet and a water outlet are arranged inside the outer shell for introducing and leading out pure water. A pure water outlet is arranged on the RO membrane filter element 4, and the water inlet of the pure water tank 5 is fixedly connected to the pure water outlet, and the water outlet of the pure water tank 5 is fixedly connected to a water pipe, and a tee is arranged on the water pipe, and a pure water reflux valve 11 is arranged on the tee pipeline, and an air filter 12 is arranged outside the pure water reflux valve 11. When the pure water refluxes, the outside air will first be filtered through the air filter 12 to prevent pollution to the pure water.
工作原理：在使用时，打开智能龙头6，其将控制进水电磁阀8打开，同时RO增压泵9将开始工作，水通过进水口进入净水器内部，制水系统将开始制水，水流进入进水口后将通过PP棉滤芯1然后经过颗粒活性炭滤芯2最后通过压缩活性炭滤芯3进行多级过滤，再经由RO增压泵9将水通过原水入口送入RO膜滤芯4内，当制水完成后关闭智能龙头6，进水电磁阀8将关闭，此时纯水回流阀11打开，同时RO废水阀10也将打开，纯水罐5中的水依靠重力反向渗透到RO膜前，膜前高浓度的RO废水排出，置换成RO纯水，当纯水回流时，外界空气会先通过空气过滤器12过滤，以防止对纯水造成污染，同时纯水罐5设置在用水管路上，与用水管路串联，等同于水管，当用户用水时，制水系统产生的新鲜纯水都会直接通过纯水罐5，这样可以保证纯水罐5内没有死水，保证水质新鲜。Working principle: When in use, turn on the smart faucet 6, which will control the water inlet solenoid valve 8 to open, and at the same time the RO booster pump 9 will start working, water will enter the water purifier through the water inlet, and the water making system will start making water. After the water enters the water inlet, it will pass through the PP cotton filter element 1 and then through the granular activated carbon filter element 2, and finally through the compressed activated carbon filter element 3 for multi-stage filtration, and then the water will be sent to the RO membrane filter element 4 through the raw water inlet through the RO booster pump 9. When the water making is completed, close the smart faucet 6, the water inlet solenoid valve 8 will be closed, and the pure water reflux valve 1 will be closed. 1 is opened, and at the same time, the RO waste water valve 10 will also be opened. The water in the pure water tank 5 relies on gravity to reversely permeate to the front of the RO membrane. The high-concentration RO waste water in front of the membrane is discharged and replaced by RO pure water. When the pure water flows back, the outside air will first be filtered through the air filter 12 to prevent pollution to the pure water. At the same time, the pure water tank 5 is arranged on the water pipe and is connected in series with the water pipe, which is equivalent to a water pipe. When the user uses water, the fresh pure water produced by the water system will directly pass through the pure water tank 5, so that there is no dead water in the pure water tank 5 and the water quality is fresh.
经实际测试，以100G的RO膜为例，当原水TDS为200，纯水TDS小于10，制完水之后30min左右，此时再次制水，初始产的水TDS值最高可达200，而且高TDS的水通常会超过200ml，若是大通量的RO膜，则初始高TDS的水量更大。而经过本方案反向冲洗后，膜前的浓缩水几乎完全被置换成纯水，此时再次制水，初始产水的TDS值最高也低于20，且很快降到10以下，几乎完全消除了RO系统首杯水TDS高的问题；要达到这样的反冲洗效果，100G的RO膜需要200ml的纯水进行反冲洗。According to actual tests, taking a 100G RO membrane as an example, when the raw water TDS is 200 and the pure water TDS is less than 10, about 30 minutes after the water is produced, the water is produced again, and the initial water TDS value can reach up to 200, and the high TDS water usually exceeds 200ml. If it is a large-flux RO membrane, the initial high TDS water volume is even greater. After the reverse flushing of this solution, the concentrated water in front of the membrane is almost completely replaced with pure water. At this time, the water is produced again, and the initial water TDS value is also less than 20 at most, and it quickly drops below 10, almost completely eliminating the problem of high TDS of the first cup of water in the RO system; to achieve such a backwashing effect, a 100G RO membrane requires 200ml of pure water for backwashing.
最后应说明的是：以上所述仅为本实用新型的优选实施例而已，并不用于限制本实用新型，尽管参照前述实施例对本实用新型进行了详细的说明，对于本领域的技术人员来说，其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换，凡在本实用新型的精神和原则之内，所做的任何修改、等同替换、改进等，均应包含在本实用新型的保护范围之内。Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
