Background technique
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
It is high the purpose of the invention is to provide a kind of discharge for being able to solve first glass of higher problem of water TDS value of big flux
The water purifier and method of TDS value pure water.
For this purpose, first technical solution of the invention is: a kind of water purifier discharging high TDS value pure water, including raw water into

It is characterized by: being divided into two-way after the pure water end connection non-return valve of the RO filter core, high-voltage switch gear, the fire hose is connected out all the way
Head, another way are connected to waste discharge mouth by the second inlet water solenoid valve；It further include control module, control module control the first water inlet electricity
The on-off of magnet valve, booster pump and the second inlet water solenoid valve；The control module opens the first water inlet electricity after high-voltage switch gear connection
Magnet valve, booster pump and the second inlet water solenoid valve, the second inlet water solenoid valve are connected to pure water end and the waste discharge mouth of RO filter core.
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, front filter element is equipped between the original water inlet and booster pump.
Second technical solution of the invention is: a method of high TDS value pure water is discharged, above-mentioned water purifier, control are used
Molding block, which is preset, rinses interval time, starts timing after high-voltage switch gear connection, reaches preset when the cumulative time
After rinsing interval time, control module opens the first inlet water solenoid valve, booster pump and the second inlet water solenoid valve, carries out to RO filter core
It rinses, and pure water is discharged from waste discharge mouth, after the completion of flushing, control module closes the first inlet water solenoid valve, booster pump and second
Inlet water solenoid valve, and restart timing.
Preferably, the control module presets the threshold value of pure water TDS value, sets when the pure water TDS value detected is greater than
When fixed pure water TDS threshold value, control module opens the first solenoid valve, booster pump and second solenoid valve, is rinsed to RO filter core,
And the pure water in RO filter core is discharged.
The present invention increases a pure water vent pathway on the basis of traditional big flux water purifier, passes through the second water inlet electricity
Magnet valve periodically opens the first inlet water solenoid valve, booster pump after water purifier shutdown to be connected to pure water end and the waste discharge mouth of RO filter core
With the second inlet water solenoid valve, RO filter core is rinsed, the pure water influenced in RO filter core by concentrated water is discharged.It is fixed that the present invention passes through
When the mode discharged remain that the water flowed out at depotition cock is the water of brand-new, prevent the TDS of pure water from rising.
TDS probe can also be arranged in the present invention at pure water outlet, detect the TDS value of pure water, when TDS value rises to centainly
When numerical value, the first inlet water solenoid valve, booster pump and the second inlet water solenoid valve are opened, RO filter core is rinsed, remains pure
The TDS value of the water at the mouth of a river is maintained in drinkable range.
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.
