Problems solved by technology

[0007] In particular, the problem of the large-flow barrelless reverse osmosis water purifier is that when it is shut down for a long time or not in use, it will have the disadvantage of low desalination rate when it is turned on again. The specific reason is that when the water purifier is shut down, the water inlet solenoid valve is closed, the booster pump stops working, and so

Embodiment 1

[0022] reverse osmosis water purifiers, such as figure 1 As shown, the pre-filter element 3, the booster pump 4, the water inlet solenoid valve 5 and the reverse osmosis membrane filter element 1 are arranged sequentially from the water inlet, wherein the pre-filter element 3, the booster pump 4, and the water inlet solenoid valve 5 are all set at On the raw water inlet pipe 11, the pretreatment of the pre-filter 3 improves the water purification effect on the one hand, and avoids the damage of the particle impurity lamp to the reverse osmosis membrane filter 1 on the other hand, and improves the service life of the reverse osmosis membrane filter 1.

[0023] The reverse osmosis membrane filter element 1 is provided with a raw water inlet, a concentrated water outlet and a purified water outlet, and the raw water inlet, the concentrated water outlet and the purified water outlet are respectively connected with a raw water inlet pipe 11, a concentrated water outlet pipe 12 and a...

Abstract

The invention relates to a domestic water purifier and discloses a reverse osmosis water purifier. The reverse osmosis water purifier comprises a reverse osmosis film filter element (1), the reverse osmosis film filter element (1) is connected with a raw water inlet pipe (11), a concentrated water outlet pipe (12) and a purified water outlet pipe (13), a pressure tank (2) is connected to the purified water outlet pipe (13) through a water storage pipe (21), and the pressure tank (2) is connected with a raw water inlet of the reverse osmosis film filter element (1) through a return pipe (23). Due to the facts that the pressure tan (2) for storing purified water is arranged in the reverse osmosis water purifier and concentrated water on the surface of a film is flushed through the purified water in the pressure tank (2), no osmotic pressure exists in a reverse osmosis film shell, the salt removing rate is high, and the TDS value of the purified water in the reverse osmosis film is effectively lowered.

Description

technical field [0001] The invention relates to a household water purifier, in particular to a reverse osmosis water purifier. Background technique [0002] Household water treatment products are becoming more and more popular, greatly improving people's quality of life. [0003] In this series of products, the core treatment technology is a unit called reverse osmosis membrane, which performs ultimate purification of source water to meet the purpose of filtering out various impurities in water. [0004] In this series of products, the general treatment process of large-flow reverse osmosis water purifiers is as follows - "water inlet ball valve, pre-filter, water inlet solenoid valve, booster pump, reverse osmosis membrane, check valve, Combination solenoid valve with waste water ratio, high pressure switch, water outlet tap, etc. [0005] The water purifier is generally in a fully automatic working state. The water purifier is directly connected to the tap water pipelin...
