Water side contacts for raw water and/or pure water rather than concentrated water.The concentrated water that 1 Central Plains of filter mechanism retains is after the discharge of wastewater outlet 13
Predeterminated position directly can be expelled to through default pipeline, waterway pipe (such as following return ducts of water purifier can also be deposited in
Road 3) in, so that water processed again after powering.Inputted for ease of flushing machine 2 into filter mechanism 1 flushing water (raw water and/or
Pure water), the concentrated water for being discharged filter mechanism 1 is preferably to discharge outside water purifier.
In the present embodiment, flushing machine 2 can be rinsed filter mechanism 1 using raw water so that filter mechanism 1
Waste water side be full of raw water.Flushing machine 2 can also be rinsed filter mechanism 1 using pure water so that filter mechanism 1 gives up
Water side is full of pure water.In addition, flushing machine 2 can also utilize the mixing water of raw water and pure water to be rinsed filter mechanism 1, make
The waste water side for obtaining filter mechanism 1 is full of mixing water.It is minimum in view of the TDS contents in the pure water for raw water, mixing water,
By pure water rinsing filter mechanism 1 can waste water side be full of pure water, and then the waste water side of filter mechanism 1 is with pure water side
Pure water, the water quality of pure water side hardly changes during water purifier is shut down, so as to ensure pure water side to greatest extent
Water quality.
In a preferred embodiment, flushing machine 2 can be rinsed filter mechanism 1 using pure water.Wherein, rinse
Pure water used in mechanism 2 can be the pure water that the filter mechanism 1 filtering is formed, or other filter assemblies (such as
Nanofiltration membrane component, ultrafiltration membrane elements, micro-filtration membrane element etc.) pure water that is formed.Preferably, for ease of 1 waste water of filter mechanism
Side is identical with the water quality of pure water side both sides, and the flushing machine 2 is with the pure water that is produced using the filter mechanism 1 by filter mechanism 1
