Water purification system and water purifier provided with same

Abstract

The invention relates to a water purification system and a water purifier provided with the same. The water purification system comprises a reverse osmosis membrane filter element, a first conductivity sensor, a TDS filter structure, a first control valve assembly and a controller, wherein the water outlet of the reverse osmosis membrane filter element is connected to a first main path, the firstmain path is branched into a first branch and a second branch, and the water outlet ends of the first and second branches are combined to form a second main path; the first conductivity sensor is arranged on the first main path; the TDS filter structure is arranged on the second branch; if the measured first TDS value is smaller than a first preset numerical value a, the controller controls the first control valve assembly, so that the first main path communicates to the first branch; if the measured first TDS value is greater than the first preset numerical value a but less than or equal to asecond preset numerical value b, the controller controls the first control valve assembly to communicate the first main path to the second branch. The water purification system can reduce the TDS content of a first cup of water intelligently, so that the user uses water more safely and sanitarily.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a water purification system and a water purifier having the same. Background technique [0002] At present, water purifiers purify water through filtering devices, while reverse osmosis water purifiers are equipment that mainly use the principle of reverse osmosis to treat water. It can not only remove impurities, rust, colloids, bacteria, and viruses, but also Remove harmful radioactive particles, organic matter, fluorescent substances, pesticides, water-alkali and heavy metals to ensure that users do not have water-alkali when boiling water. Therefore, the pure water produced by the reverse osmosis water purification machine is fresher than bottled water , more hygienic, safer, and more and more favored by users. [0003] However, the reverse osmosis water purifier has the problem of high content of TDS (Total dissolved solids) in the first few cups of water when th...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects of high TDS content and waste of water resources in the first few cups of water when the reverse osmosis water purifier in the prior art is shut down and restarted to take water, so as to provide a reverse osmosis water purifier that can make reverse osmosis When the water purifier is turned off and then turned on to fetch water, the first few cups of water have low TDS content and do not waste water resources. The water purification system and the water purifier with it
