Problems solved by technology

[0004] The previous reverse osmosis membrane water purifiers were concentrated water discharge type, that is, the concentrated water after primary purification and filtration was discharged directly as waste water, which is indeed a great waste, especially for small household and commercial water purifiers. , the raw water is tap water, the water quality of the concentrated water produced after one purification and filtration is not worse than that of the raw water, and it has the value of utilization, and can be further purified twice or three times. If the concentrated water is directly discharged as waste water, it will not only Increase the cost of water purification, and it is also a waste of water resources

Embodiment 1

[0062] Such as figure 1 As shown, the non-wastewater water purifier of this embodiment includes a pre-filter 20, a water inlet solenoid valve 30, a water pump 40, a filter element mechanism and an RO membrane filter element 60 connected sequentially through pipelines, and the water purifier also Including limited flow and circulation solenoid valve 140, one-way valve 100, high pressure switch 210, water storage tank 130 and post filter 120,

[0063] The pre-filter 20 is connected to the raw water pipeline 10, and the water purification outlet of the RO membrane filter element 60 is connected to a water purification outlet pipe 71, and the outlet end of the water purification outlet pipe 71 is connected to a pure water pipe 712, and the pure water pipe 712 The one-way valve 100 and the post-filter 120 are arranged in sequence along the water flow direction, the water outlet end of the post-filter 120 is connected with a pure water faucet 190, and the pure water pipe 712 at the...

Embodiment 2

[0087] Such as figure 2 As shown, the filter element mechanism of the present embodiment includes a secondary composite filter element 54 and a tertiary composite filter element 55 connected in parallel, and the water outlet ends of the secondary composite filter element 54 and the tertiary composite filter element 55 are connected to the RO membrane filter element respectively. 60, the pre-filter 20 is an origami filter element with a pore size of 20 μm.

[0088] The second-stage composite filter element 54 and the third-stage composite filter element 55 in this embodiment are all composite filter elements of sintered activated carbon columns and PP cotton. The outer layer of the composite filter element is PP cotton with a pore size of 1-5 μm, and the PP cotton is filled with Sintered activated carbon column, the sintered activated carbon column is a hollow structure.

[0089] The function of the origami filter element is to filter larger particles in the raw water, so tha...

Abstract

The invention relates to the technical field of water purifiers, in particular to a wastewater-free water purifier. The water purifier includes a pre-filter, a water inflow electromagnetic valve, a water pump, a filter core mechanism and an RO membrane filter core that are connected in order through a pipeline, and also includes a current limiting and circulating electromagnetic valve, a one-way valve, a high voltage switch, a water storage bucket and a post-filter. The pre-filter is connected to a raw water pipeline, the pure water outlet of the RO membrane filter core is connected to a pure water outlet pipe, the outlet end of the pure water outlet pipe is connected to a pure water pipe, and the pure water pipe is equipped with the one-way valve and the post-filter in order along the water flow direction. The concentrated water outlet of the RO membrane filter core is connected to a concentrated water outlet pipe, the outlet end of the concentrated water outlet pipe is respectively connected to a concentrated water return pipe and a domestic water pipeline, the concentrated water return pipe is equipped with the current limiting and circulating electromagnetic valve, and the water outlet end of the concentrated water return pipe is connected to the water inlet end of the water pump. The water purifier can realize unnecessary discharge of concentrated water during pure water making and achieves the function of no wastewater discharge, and during use of domestic water, the concentrated water is used reasonably.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a waste water-free water purifier. Background technique [0002] RO reverse osmosis membrane direct drinking machine is also called RO reverse osmosis membrane water purifier. The full name of RO in English is: Reverse Osmosis, that is, reverse osmosis. The reverse osmosis membrane filter cartridge is equipped with a reverse osmosis membrane filter element. Under a certain pressure, water molecules can pass through the RO membrane, while impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria, and viruses in the water cannot pass through the RO membrane. membrane, so that part of the water is separated through the RO membrane, and the unpermeable water forms concentrated water due to the increase of solute. Reverse osmosis membrane water purifiers were used in industrial fields such as seawater and brackish water desalination, boiler feed...
