Water purifier

Abstract

The invention relates to a water purifier which comprises a cabinet, a controller, a water supply pipeline, a purified water making pipeline, a domestic water pipeline, a concentrated water recycling pipeline and a depressurization safe water draining pipeline. The water supply pipeline, the purified water making pipeline, the domestic water pipeline, the concentrated water recycling pipeline and the depressurization safe water draining pipeline are arranged in the cabinet, a first pressure sensor and a first electromagnetic valve are arranged on the water supply pipeline, the purified water making pipeline comprises a filter element set, a water storage pressure barrel and a purified water faucet, and a pressurizing pump is arranged on a pipeline communicating a PVDF ultrafiltration membrane filter element and a RO membrane filter core; a water inlet of a postpositive activated carbon filter element is communicated with the water storage pressure barrel while a water outlet of the same is communicated with the purified water faucet, and the concentrated water recycling pipeline comprises a concentrated water chromatography tank, a throttling valve and a water quality detector. Through the technical scheme, tap water waste caused by free discharging of concentrated water in the process of purified water making in the prior art can be reduced, and artificial participation can be reduced.

Description

technical field [0001] The invention relates to the technical field of water treatment equipment, in particular to a water purifier. Background technique [0002] Water purifiers, also called water purifiers and filters, are small water treatment equipment that perform deep purification of water quality according to the requirements of water use. [0003] Water purifiers can be divided into many types according to different purification principles and processes. Among them, RO reverse osmosis technology has the highest filtering accuracy (filtering accuracy is 0.0001 microns). Since the pore size of the reverse osmosis membrane is five millionths of that of a hair, only water molecules and dissolved oxygen are allowed to pass through. Harmful substances such as bacteria, viruses, and heavy metals are almost completely intercepted and excluded. In addition to reverse osmosis technology, there are many other filtration technologies: nanofiltration (filtration accuracy betwee...
