Description

Intelligent water-saving type anti-penetration water purifier and its process for purifying water with reflux
Technical field
The present invention relates to Water warfare field, more particularly to a kind of Intelligent water-saving type anti-penetration water purifier with reflux And its process for purifying water.
Background technology
The demand in market promotes the fast development of water purifier, at present water purifier on the market either from filtering technique, Structure design, or electric-controlled intelligent, man-machine interaction are all constantly being lifted.Occur in the prior art using reverse osmosis membrane Water correction plant.
Counter-infiltration (RO) film is because its pore size filter only has 0.0001 micron, therefore surface easily blocks, and the performance of film is held Easily influenceed by chlorine residue, organic matter etc., and counter-infiltration (RO) film cost itself is higher, even if 50G counter-infiltration (RO) film Also will nearly 100 yuans, counter-infiltration (RO) film of bigger gallon even wants thousands of members.Therefore, in order to protect counter-infiltration (RO) film, extend its service life, reduce the use cost of consumer, almost all of purifier is using counter-infiltration (RO) First running water is pre-processed from other filter cores before film, to go to suspension in removing water, particle, chlorine residue and part organic Thing etc., it then can just enter counter-infiltration (RO) film by pretreated water and carry out further filtration, purification.But this mode The problem of existing problems with:
1st, the water after preprocessing filter element purifies is not reasonably utilized;
2nd, counter-infiltration (RO) water purifier must produce concentration because of the limitation of its operation principle during water purification is prepared Water, and traditional counter-infiltration (RO) film is pure useless than being 1:3, that is, also along with the generation of 3L condensed waters while producing 1L pure water. Condensed water can not be drunk, and most water purifier producer can select directly to discharge it.
Above-mentioned two problems are undoubtedly to be wasted to one kind of water resource.
The content of the invention
It is an object of the invention to provide a kind of Intelligent water-saving type anti-penetration water purifier and its water purification with reflux Method, so as to solve foregoing problems present in prior art.
To achieve these goals, the Intelligent water-saving type anti-penetration water purifier of the present invention with reflux, it is described Water purifier includes water purifier main body, is set in the water purifier main body:The first preprocessing filter element for sequentially connecting, the second pre- place Reason filter core and counter-infiltration filter core, first preprocessing filter element connect with water inlet, and the counter-infiltration filter core goes out with pure water respectively The mouth of a river connects with concentrated water discharge outlet;
