Water purifier

Abstract

The invention discloses a water purifier, and relates to a novel household water purifier (RO) and a nanofilter (NF) suitable for preparing pure water of general municipal direct-supply tap water (water pressure is greater than or equal to 0.2MPa). The water purifier comprises a case, an electromagnetic valve, a Hall flowmeter, a preprocessor, a reverse osmosis processor, a pure water storage tank, a pure water outlet pump, an electric control faucet, a thick water outlet pump, a thick water storage tank and a thick water proportioner, wherein the water inlet of the electromagnetic valve is connected with a tap water pipeline through a water inlet pipe; the water outlet of the electromagnetic valve is connected with the water inlet of the Hall flowmeter through a pipeline; the water outlet of the Hall flowmeter is connected with the water inlet of the preprocessor through a pipeline; the water outlet of the preprocessor is connected with the water inlet of the reverse osmosis processor through a pipeline; the pure water outlet of the reverse osmosis filter is connected with the pure water storage tank; the thick water outlet of the reverse osmosis filter is connected with the thick water storage tank through the thick water proportioned and a pipeline; and the outlet of the pure water outlet pump is connected with the electric control faucet through a pipeline.

Description

technical field [0001] A pure water machine of the present invention relates to a new household pure water machine (RO) and a nanofiltration machine (NF), which are suitable for producing pure water for general municipal direct supply tap water (water pressure ≥ 0.2 MPa). Background technique [0002] At present, RO / NF systems of household water purifiers generally use booster pumps to drive reverse osmosis membranes to produce pure water, and concentrated water generated by RO / NF membranes is directly drained from the sewer or collected in containers. The high internal pressure of the above-mentioned system leads to an increase in failure rate and hidden dangers of water leakage, making it difficult to collect concentrated water and difficult to operate. However, the pressure tank for storing pure water has the disadvantages that it cannot be cleaned and is prone to air leakage, resulting in no water.

Problems solved by technology

[0003] The purpose of the present invention is to propose a pure water machine for the above shortcomings, which is to make a major improvement against the shortcomings of various types of RO / NF systems, such as the large amount of concentrated water, which is difficult to recover, and the high failure rate caused by excessive pressure. It is suitable for general municipal direct Production of pure water for tap water (water pressure ≥ 0.2MPa)
