Abstract

The invention relates to the field of water purification and discloses a water purifier with the function of reducing a TDS (Total Dissolved Solids) value of re-yielded water. The water purifier comprises a reverse osmosis membrane filter element (1), wherein a water inlet electromagnetic valve (21) is arranged on a raw water inlet pipe (2), and a first water outlet electromagnetic valve (41) and a high-pressure switch (43) are sequentially arranged on a purified water outlet pipe (4). The water purifier further comprises a water drain pipe (5), wherein one end of the water drain pipe (5) is connected with a water inlet of the first water outlet electromagnetic valve (41), and the other end of the water drain pipe (5) is connected with a concentrated water outlet pipe (3); a second water outlet electromagnetic valve (51) is arranged on the water drain pipe (5), and the water inlet electromagnetic valve (21), the first water outlet electromagnetic valve (41), the second water outlet electromagnetic valve (51) and the high-pressure switch (43) are all connected with a controller. According to the water purifier, the water drain pipe (5), which is used for draining high-TDS-value purified water prepared by the reverse osmosis membrane filter element (1), is connected between a purified water outlet and a concentrated water outlet, so that the high-TDS-value purified water is effectively prevented from being drained from the purified water outlet, and healthy drinking water for users is guaranteed.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a water purifier with the function of reducing the TDS value of re-effluent water. Background technique [0002] When a water purifier equipped with a large-flux reverse osmosis membrane filter element is shut down for a certain period of time to produce pure water, the TDS value (dissolved solids content) of the purified water produced in the previous period is relatively high, even close to the TDS value of the raw water. If the amount of water taken by the user is not very large, the water taken each time is water with a high TDS value, which seriously affects the quality of drinking water and greatly reduces the role of the water purifier. Contents of the invention [0003] The present invention aims at the problem in the prior art that the TDS value in the early stage is relatively high when the water purifier takes water each time, and provides a water purifier with the ...
