Description
Technical field
The utility model relates to water-purifying machine, and two water outlet reverse osmosis water purifiers of a kind of pair of mutual wash type of film particularly belong to the improvement technology of existing pair of water outlet reverse osmosis water purifier.
Background technology
The current raising along with people's living standard, the cleanliness factor of tap water is required also to improve constantly, and water pollutes constantly aggravation, water-purifying machine progressively enters ordinary citizen's family, wherein reverse osmosis water purifier is as the highest product of a kind of filtering precision, because of its water purification effective, moderate cost, the parent who is subject to users looks at, and reverse osmosis water purifier has become the first-selection of safty of drinking water.But family is except daily drinking-water, washing and culinary art water have also occupied very large proportion, as all adopted reverse-osmosis pure water, use cost will be very high (because of reverse osmosis membrane, RO membrane lifetime can significantly shorten, and it changes price very expensive), simultaneously, because the water production rate of RO film is conventionally less, be also difficult to meet washing requirement, if continue, adopt and exist the tap water polluting more inadvisable.Therefore, the ultrafiltration water that use flux is larger, the relative tap water of water quality is safer, as washing and culinary art water, is very wise selection.People have designed two discharging type reverse osmosis water purifiers for this reason.
The two discharging type reverse osmosis water purifiers that exist are in the market broadly divided into two types.
Directly the water after the preposition pretreatment system simple filtration of reverse osmosis membrane is directly drawn as two water outlets, this water is because failing thoroughly to remove the objectionable impuritiess such as bacterium in water, iron rust, colloid, and water quality is also dangerous.Shown in Fig. 1 is exactly the reverse osmosis water purifier of a kind of pair of discharging type like this, as shown in Figure 1, during its work, tap water directly enters successively the first preprocessing filter element 1, the second preprocessing filter element 3 and the 3rd preprocessing filter element 4 and processes, after processing, the moisture of output becomes two-way: a road directly flows to two depotition cocks, for washing and culinary art, this part water is because failing thoroughly to remove the objectionable impuritiess such as bacterium in water, iron rust, colloid, and water quality is also dangerous; , after topping-up pump 2 superchargings, then further filter through reverse osmosis membrane 5 on another road, and after filtration, be further divided into two-way ，Yi road just becomes the two depotition cocks of the pure water flow direction after filtration through rearmounted filter core, for directly drinking; Another road is condensed water and discharges through waste water combination valve 7.
Another kind of similar to the above-mentioned type, difference is water purification degree after ultra-filtration membrane being set in the preposition pretreatment system of reverse osmosis membrane and improving pre-treatment, and then wherein a part of water directly flows to pair depotition cocks, for washing and cooking.It is exactly the reverse osmosis water purifier of a kind of pair of discharging type like this that Fig. 2 illustrates, as shown in Figure 2, during its work, tap water directly enters successively the first preprocessing filter element 1, the second preprocessing filter element 3 and ultra-filtration membrane 41 and processes, after processing, the moisture of output becomes two-way: a road directly flows to two depotition cocks, for washing and culinary art; , after topping-up pump 2 superchargings, then further filter through reverse osmosis membrane 5 on another road, and after filtration, be further divided into two-way ，Yi road just becomes the two depotition cocks of the pure water flow direction after filtration through rearmounted filter core, for directly drinking; Another road is condensed water and discharges through waste water combination valve 7.In this water-purifying machine; described ultra-filtration membrane 41 is in washing culinary art and directly drink two kinds with all participating in filtration under water state; and there is no automatic flushing device; the life-span of ultra-filtration membrane 41 will significantly shorten, and after its obstruction, reverse osmosis membrane system is also by influenced; water production rate reduces; system operation time will significantly increase and even occur not machine halt trouble, and then shorten reverse osmosis membrane system as the work-ing life of a series of components and parts such as film, pump, valve, high-voltage switch gear, greatly increase user's use cost.
