First embodiment
A kind of delay shutdown type household water purifier 100 is present embodiments provided, it is shown referring to Fig.1 comprising booster pump
110, film desalination unit 120, electro-desalting unit 130 and delay controller (not shown).
Wherein, the input terminal of booster pump 110 is connected to by normal pressure water-supply-pipe 141 with raw water source.In general, raw water source is
Municipal tap water, it is not limited to municipal tap water, is also possible to other water sources.Booster pump 110 is for increasing raw water
Pressure, and it is delivered to film desalination unit 120.
Further, film desalination unit 120 includes any one of nano filter membrance device and reverse osmosis membrane apparatus.Specifically,
Film desalination unit 120 has the first water inlet, the outlet of the first concentrated water and the first production water out.First water inlet passes through high pressure
Water-supply-pipe 142 is connected to the output end of booster pump 110, and the first production water out is connected to by outlet pipe 143 with water terminal.Pressurization
Water afterwards is entered in film desalination unit 120 by high pressure water transport pipe 142 through the first water inlet, after film desalting processing, is obtained
Pure water and concentrated water, pure water produce water out by first, and the use water terminal of user, such as tap etc. are delivered to through outlet pipe 143.It produces
Raw concentrated water is then delivered to electro-desalting unit 130 by the outlet of the first concentrated water and is further processed.
Optionally, electro-desalting unit 130 includes any one of electrodialysis plant and capacitor desalter；Preferably,
Electrodialysis plant includes pole-reversing electroosmosis device.Specifically, electro-desalting unit 130 have the second water inlet, the second concentrated water outlet,
And second produce water out.First concentrated water outlet of the second water inlet and film desalination unit 120, the second production water out pass through
Reflux line 144 is connected to normal pressure water-supply-pipe 141.The outlet of second concentrated water is connected to concentrated water discharge pipe 145.It is exported by the first concentrated water
The concentrated water of discharge is entered in electro-desalting unit 130 by the second water inlet, is handled by electro-desalting, and it is lower to generate salt content
Recyclable water and the higher super concentrated water of salt content.Recyclable water produces water out discharge by second, flows by reflux line 144
It returns in normal pressure water-supply-pipe 141 and is mixed with raw water, it is de- to be delivered to progress film in film desalination unit 120 again via booster pump 110
Salt treatment.
In the present embodiment, the first solenoid valve for controlling the first production water out opening and closing is provided at the first production water out
146；Second concentrated water exit is provided with the second solenoid valve 147 for controlling the second concentrated water outlet opening and closing.Delay controller point
It is not electrically connected with booster pump 110, electro-desalting unit 130, the first solenoid valve 146 and second solenoid valve 147, to control booster pump
110 and electro-desalting unit 130 time-delay closing and the first solenoid valve 146 and second solenoid valve 147 opening and closing.In film desalination
After unit 120 is out of service, delay controller controls the first solenoid valve 146 and closes, i.e., stopper film desalination unit 120 produces water side
Water flowing.Meanwhile the normal operation of booster pump 110 and electro-desalting unit 130 is maintained, the entire shutdown type household water purifier that is delayed
Water in 100 forms circulation loop between booster pump 110, film desalination unit 120, electro-desalting unit 130, makes film desalination unit
The concentrated water of 120 concentrated water sides, which can remain in operation, carries out electro-desalting into electro-desalting unit 130, until 120 concentrated water of film desalination unit
Side is suitable with the salinity of water side is produced.It is worth noting that, the second electromagnetism can be kept when carrying out above-mentioned circulation desalination processes
Valve 147 is in the open state, keeps the concentrated water discharge of electro-desalting unit 130, at this point, in order to maintain the water in circulation loop,
Raw water can be supplemented by normal pressure water-supply-pipe 141.In addition to this, second solenoid valve 147 can also be closed namely electro-desalting unit
130 are discharged without concentrated water, at this point, salinity is only accumulated in the concentrated water side of electro-desalting unit 130, and the water in circulation loop does not have
It is reduced, does not need additionally to supplement raw water.Two kinds of processing modes, the former is suitble to 120 concentrated water side salinity of film desalination unit higher
The case where, and the situation that the latter is then relatively suitble to 120 concentrated water side salinity of film desalination unit lower.
Second embodiment

In concentrated water contain more salinity and other impurity, be not appropriate for directly drinking, but its can still apply it is right at some other
Water scene of less demanding, such as flushing the toilet, putting on the skin floor etc..And in the prior art, concentrated water causes water often by direct emission
The waste of resource.Concentrated water can be stored by adding concentrated water storage tank 410 then, give over to other places and use.
Preferably, the outlet of the first concentrated water is by by-pass line 420, around electro-desalting unit 130 and concentrated water storage tank 410 into
Water end (W.E.) connection.Specifically, the first concentrated water exit is provided with triple valve, triple valve respectively with by-pass line 420 and electro-desalting list
Member 130 is connected to.For certain specific conditions, when demand of the user for concentrated water is larger, the unlatching of adjustable triple valve
State, by film desalination unit 120, treated that concentrated water directly passes through by-pass line 420 is delivered to concentrated water storage tank 410 and uses, with full
Use of the sufficient user to concentrated water.
In conclusion the embodiment of the invention provides a kind of delay shutdown type household water purifiers comprising booster pump, film
Desalination unit and electro-desalting unit, wherein the second water inlet of the first concentrated water outlet and electro-desalting unit of film desalination unit
Connection.After film desalting processing, the concentrated water of generation is transported to electro-desalting unit and is further processed, and carries out to moisture therein
Recycling.The moisture of recycling is transmitted back to normal pressure water-supply-pipe, then is delivered to the processing of film desalination unit via booster pump.The delay is shut down
The setting of type household water purifier is rationally, easy to operate, by adding electro-desalting step, the shutdown type Domestic water purifying that will entirely be delayed dress
It sets and 90% or more is increased to the utilization rate of water, achieve the purpose that save water resource.In addition, the delay shutdown type Domestic water purifying fills
It sets including delay controller, can control booster pump and electro-desalting unit when continuing to run one section after film desalination unit is closed
Between, film desalination unit is reduced in the salinity of concentrated water side, is avoided salinity from infiltrating into initial water concentration caused by producing water side and is increased.
Another object of the present invention is to provide a kind of domestic water purifying machines comprising above-mentioned delay shutdown type Domestic water purifying dress
It sets.Its equipment is simple, easy to operate, and purifying water effect is good, high to the utilization rate of water, can effectively save water resource.Meanwhile very well
Solve the problems, such as initially produce water salinity raising, reach better purifying water effect.
The foregoing is only a preferred embodiment of the present invention, is not intended to restrict the invention, for the skill of this field
For art personnel, the invention may be variously modified and varied.All within the spirits and principles of the present invention, made any to repair
Change, equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
