Description
Technical field
The invention belongs to purifier technical field, in particular to a kind of water purifier and method with pure water displacement concentrated water.
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, and user's RO film when stopping using is intake
The concentrated water at end can be gradually diffused into pure water end, and the time of diffusion started to show at 5 minutes or more, the general root of the water at pure water end
Depending on the size of putamina, 500-1000ml or so is generally had, also results in restarting first glass of water TDS value after work
It is 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 with pure water
Replace the water purifier and method of concentrated water.
For this purpose, first technical solution of the invention is: a kind of water purifier with pure water displacement concentrated water, it is characterised in that:

Second inlet water solenoid valve is connected to original water inlet, and the pure water end of the 2nd RO filter core is connected with the water inlet end of the first RO filter core.
Preferably, the working condition of first inlet water solenoid valve and the second inlet water solenoid valve is mutually staggered, i.e., first into
When water solenoid valve is in running order, the second inlet water solenoid valve is that off working state or the second inlet water solenoid valve are in work
When state, the first inlet water solenoid valve is off working state.
Preferably, the pure water end of the first RO filter core connects depotition cock by the first non-return valve, high-voltage switch gear；It is described
The concentrated water end of first RO filter core is connected to waste discharge mouth by the first concentrated water solenoid valve, and the concentrated water end of the 2nd RO filter core is dense by second
Water solenoid valve is connected to waste discharge mouth.
Preferably, flow-limiting valve is equipped between second inlet water solenoid valve and the 2nd RO filter core.
Preferably, a flow-limiting passage, flow-limiting passage one end are drawn between second inlet water solenoid valve and the 2nd RO filter core
Equipped with metering hole, between the second inlet water solenoid valve and the 2nd RO filter core, before the other end is connected to the water inlet end of booster pump, and
Flow-limiting passage is equipped with third non-return valve.
Preferably, front filter element is equipped between the original water inlet and booster pump.
Preferably, the capacity of the 2nd RO filter core is less than the first RO filter core.
Second technical solution of the invention is: a method of it is beaten with pure water displacement concentrated water using above-mentioned water purifier
When outputing tap, the first inlet water solenoid valve is opened, the normal water processed of the first RO filter core, and the second inlet water solenoid valve is to close shape at this time
State；When closing depotition cock, the first inlet water solenoid valve is closed, and the second inlet water solenoid valve is opened, and the normal water processed of the 2nd RO filter core produces
Raw pure water enters the water inlet end of the first RO filter core by the second non-return valve, so that the first RO filter core is using in pure water displacement filter core
Concentrated water, after concentrated water is discharged, close booster pump, the second inlet water solenoid valve.
Due to the problems of liquid flow of booster pump, the first inlet water solenoid valve is closed, in the case that the second inlet water solenoid valve is opened, work
It is too big to make pressure, flow-limiting valve need to be increased or draws flow-limiting passage, the operating pressure of the 2nd RO filter core is made to be adjusted to normal work
Make range.
The present invention increases the 2nd RO filter core an of low capacity on the basis of traditional big flux water purifier, and is shutting down
Afterwards, the concentrated water in the first RO filter core of displacement is gone using the pure water that the 2nd RO filter core generates, so that in the concentrated water end of the first RO filter core
All become pure water, solve ion diffusion problem, increase the TDS of pure water in pure water end will not, solves in this way big
The higher problem of first glass of water TDS value of flux.
