The water purifier can also comprise a third filter element, and the pure water in the pure water pipe 20 can also be continuously introduced into filter materials such as a rear carbon rod in the third filter element to further finely filter and deeply purify the pure water, so that the pure water can more thoroughly adsorb the abnormal color and the peculiar smell in the pure water, and the taste of the pure water is adjusted.
The concentrated water generated after being filtered and purified by the filter membrane 54 can enter the concentrated water channel through the second through hole, and then a part of concentrated water enters the wastewater pipe 10 through the concentrated water channel and is discharged through the wastewater hole 11; the other part of the concentrated water enters the concentrated water return pipe 30, is discharged to a corresponding pipeline through the concentrated water return hole 31, and is converged into the first purified water pipe 40. The mixed liquid of the purified water and the discharged concentrated water is pressurized by a water pump, so that the mixed liquid enters the water purifying flow of the water purifier again. Therefore, the waste water discharge amount of the water purifier can be reduced, the water production rate of the water purifier is also improved, and the water utilization rate is greatly improved.
The water purifier in the embodiment adopts the waste water hole 11 and the concentrated water return hole 31 to replace the existing waste water valve in the water purifier, and realizes waste water throttling and discharging through the waste water hole 11 and the concentrated water return hole 31. Since no waste water valve is provided, the structure of the water purifier is simplified. In addition, the process of perforating the concentrated water return pipe 30 and the waste water pipe 10 is simple and easy to operate, so that the production cost of the water purifier can be greatly saved, and the production efficiency is improved.
In addition, the concentrated water in the concentrated water return pipe 30 is recovered by the concentrated water return hole 31, the recovery rate of the waste water can be improved, and the concentrated water in the waste water pipe 10 is discharged by the waste water hole 11, so that the filtering material such as a reverse osmosis membrane in the first filter element 50 can be cleaned, the concentration of the waste water is prevented from being increased sharply, the reverse osmosis membrane pollution caused by the blockage of the filtering material such as the reverse osmosis membrane in the first filter element 50 is avoided, and the service life of the water purifier is prolonged.
