Traditional reverse osmosis water purifier, water-making ability are usually daily 50 gallons, and water-making ability adds from 400 gallons to 800
Logical sequence or even 1000 add logical sequence and be commonly referred to as big flux water purifier, big flux water purifier is also being defended while improving certain performances
New problem is brought in terms of raw index and cost performance, produces " Su Shui " problem.
The pipelined channel of reverse osmosis membrane filter element (RO filter core) is all such as flowering structure at present: raw water enters from one end of filter core,
Raw water filters from outside to inside, and filtered pure water is gone out by central tube, and filtered concentrated water is in the outside of central tube.Reverse osmosis
The concentrated water of diafiltration core concentrated water side, ion, the organic matter of contained high concentration can be slowly diffused into pure water side, if the time
Long enough can make the concentration of two sides reach balance.If passing through the diffusion at a night, the TDS value of pure water will in pure water side
Apparent increase, if heavy metal ion is more in raw water, the heavy metal in pure water also can be exceeded, and water quality, mouthfeel all can be big
It is impacted.
At work, the TDS at pure water end is in normal condition to big flux water purifier, user when stopping using, RO film into
The concentrated water of water end (W.E.) can be gradually diffused into pure water end, and the time of diffusion started to show at 5 minutes or more, and the water at pure water end is general
Depending on the size of putamina, 500-1000ml or so is generally had, also results in restarting first glass of water TDS after work
It is worth higher.
Summary of the invention
The purpose of the invention is to provide it is a kind of be able to solve first glass of higher problem of water TDS value of big flux using pure
The water purifier and method of water replacement concentrated water.
For this purpose, first technical solution of the invention is: it is a kind of using pure water replacement concentrated water water purifier, including raw water into
Mouthful, original water inlet is sequentially connected the first inlet water solenoid valve and booster pump；The water inlet end of the booster pump connection RO filter core, RO filter core

It is characterized by: the pure water end of the RO filter core is divided into two-way, it is connected to out all the way by the first non-return valve, high-voltage switch gear
Tap, another way are connected to the water inlet of booster pump by the second inlet water solenoid valve, the second non-return valve；It further include control mould
Block, control module control the first inlet water solenoid valve, the on-off of booster pump and the second inlet water solenoid valve.
Preferably, the pure water end of the second inlet water solenoid valve connection RO filter core and water inlet end.
Preferably, it is provided with TDS probe on the pipeline of the pure water end connection depotition cock of the RO filter core, detects pure water
TDS value.
Preferably, first, second inlet water solenoid valve is flow control valve, and control module adjusts the first, second water inlet
The flow of solenoid valve.
Second technical solution of the invention is: a method of concentrated water being replaced using pure water, using above-mentioned water purifier,
When opening depotition cock, the first inlet water solenoid valve is opened, and the second inlet water solenoid valve is closed, the normal water processed of RO filter core；Close water outlet
When leading, the second inlet water solenoid valve open, the first inlet water solenoid valve operation a period of time after close, RO filter core generate pure water into
The water inlet end for entering RO filter core is mixed with raw water, to replace the concentrated water in RO filter core, is counted since being closed the first inlet water solenoid valve
When, after reaching setting time, close booster pump, the second inlet water solenoid valve.
Preferably, when opening depotition cock, the first inlet water solenoid valve is opened, and the second inlet water solenoid valve is closed again after opening 5 seconds
It closes.
Preferably, when closing depotition cock, the first inlet water solenoid valve is closed after running 1 minute, and the first inlet water solenoid valve is closed
After closing 30 seconds, booster pump, the second inlet water solenoid valve are closed.
Preferably, after closing depotition cock 10 seconds, concentrated water solenoid valve is full-gear.
Preferably, the control module adjusts the flow of the first, second inlet water solenoid valve, that is, adjusts according to pure water TDS value
Into the pure water and raw water ratio of RO filter core.
First, second inlet water solenoid valve of the invention can be fabricated to adjustable flow valve, after a shutdown can be according to TDS value tune
Rectification flow, so as to adjust the ratio for entering raw water and pure water in RO filter core, more accurate reduction TDS value.
The present invention increases a pure water current return circuit on the basis of traditional big flux water purifier, and after a shutdown, utilizes
RO filter core generate pure water go displacement RO filter core itself in concentrated water so that all become in the concentrated water end of RO filter core raw water with it is pure
The mixing raw water of water reduces the ion concentration of concentrated water side in RO filter core, solves ion diffusion problem, makes pure water in pure water end
TDS will not be increased, and solve the problems, such as that first glass of water TDS value of big flux is higher by this pure water reflux type.
Detailed description of the invention
It is described in further detail below in conjunction with attached drawing and embodiments of the present invention
Fig. 1 is structure principle chart of the invention.
