Description
Technical field
The invention belongs to household electrical appliance technical field, specifically, is related to a kind of reverse osmosis purified water system.
Background technology
At present, with it is industrialized development and people door improvement of living standard, the pollution that water resource is subject to it is more and more tighter
Weight, people also increasingly pay attention to the quality of water resource, for this reason, more and more water treatment technologies spread to normal domestic neck
Domain, corresponding Water warfare product are also promoted therewith, can be produced in existing anti-penetration water purifier water on the market a large amount of
Concentrated water, and these concentrated waters are to be exhausted directly to sewer to flow away, and which results in serious waste.
The best anti-penetration water purifier of filter effect has obtained unprecedented favor, is especially even more to flow currently on the market
The substantial amounts of reverse osmosis water purifier of row, a large amount of reverse osmosis water purifiers eliminate the pressure pot that may be grown bacterium and produce peculiar smell,
But when for a long time without using water purifier, when fetching water first, there are an impregnation process, this phase in when water flowing first due to reverse osmosis membrane
Between a small amount of residuals present in membrane material production can be dissolved in water and be washed out, pure water when showing just to start
TDS is exceeded, and for a user, it is most using the situation of water first, this has resulted in most of the time use
Pure water be all to have taken the exceeded water of TDS.
This problem is not solved effectively at present, and some producers are provided with light prompt, and Huang is shown when TDS is exceeded
Lamp, shows green light when TDS is normal, warning user just starts to fetch water when giving a green light, this brings puzzlement to user, because water
Flowing always, there is very big pressure at heart, to stare at current and indicator light the moment, the experience of user is poor.
The patent of Application No. 201410824527.6 discloses a kind of saving type RO membrane water purifier, the water purifier bag
Include pre-filtering device, booster pump, TDS detectors, reverse osmosis membrane filtration component, double taps, pressure water storage tank, bypass electromagnetism
