Many, and waste water, water purifier can preset cleaning duration as user with the persistent period that water end (W.E.) 10 is in closing more than first
When, water purifier enters cleaning state.For example, the first default cleaning duration can be arranged to 12 hours, typically, by water storage
After in device 2, pure water is carried out to defecator 1, the total dissolved solidss of defecator 1 its internal water within a certain period of time
Will not occur significantly raised, so when the firm water outlet of water purifier can effectively be reduced by setting rational first default cleaning duration
Total dissolved solidss moreover it is possible to the waste water resource that avoids the number of times cleaning excessive and cause.
Because user is likely to occur long-time non-someone's water with water end (W.E.) 10, water storage device 2 filters dress in upper once cleaning
After putting 1, do not have an opportunity to carry out storing water.So when user is in persistent period default cleaning more than second of closing with water end (W.E.) 10
During duration, water purifier opens water pump 5, so that first chamber 21 water storage, and enter cleaning state；Wherein, during the second default cleaning
Long cleaning duration default more than first.
When user the situation of longer time non-someone's water with water end (W.E.) 10, such as user goes on business and does not use for a long time
Water purifier, water purifier unused time enters holding state after reaching default standby time, and in the standby state, water purifier will not
Defecator 1 is carried out.In these cases, as shown in figure 5, water purifier also includes being arranged on user with water end (W.E.) 10 and storage
The 4th switching device 38 between water installations 2, after user exceedes default standby time with the persistent period that water end (W.E.) 10 is closed, uses
Family water end (W.E.) 10 is opened (user reuses water purifier), and because water purifier is not used by for a long time, now water purifier first will
Water storage device 2 is carried out with water storage operation and defecator 1 is carried out.The operation of water purifier is as follows, and water purifier closes the 4th
Switching device 38, and open water pump 5 so that first chamber 21 water storage, and enter cleaning state；After water purifier completes cleaning state,
Open the 4th switching device 38, so that water purification function provides pure water to user with water end (W.E.) 10；Wherein default standby time is more than the
Two default cleaning durations.In the above case said, water purifier is also provided with display screen, be opened with water end (W.E.) 10 as user and
In the case of not having water outlet, display screen can show and the captions such as example " is carried out, please somewhat ", net to inform user
Water dispenser is carried out operating and does not have pure water to flow out.
Above-mentioned water purifier can be carried out to defecator 1 according to the actual service condition to water purifier of user, so,
When effectively reducing purifier water outlet under wash number as few as possible, the total dissolved solidss (tds) of first glass of pure water, are saving
On the premise of water, reduce prolonged and repeated cleaning and defecator 1 is caused damage, and then increase the service life of water purifier.

Work on, so that reverse osmosis membrane apparatus a1 continues to produce pure water；Under the pressure that water pump a5 provides, make first chamber a21
Volume increases, and storage pure water is for the cleaning of reverse osmosis membrane apparatus a1；Water purifier has cleaning state and controlling the water circulation state: clear
Wash under state, first chamber a21 is disconnected with pure water mouth a11, and first chamber a21 is connected with raw water mouth a13, in first chamber a21
Pure water flow into from the raw water mouth a13 of reverse osmosis membrane apparatus a1 and discharge from the concentrated water spout a12 of reverse osmosis membrane apparatus a1；In controlling the water circulation
Under state, first chamber a21 is connected with pure water mouth a11, and the pure water that reverse osmosis membrane apparatus a1 produces arrives via after first chamber a21
Reach user and use water end (W.E.) a10.
It is in daily open state in water purifier, when user is opened with water end (W.E.) a10, then water purifier is under controlling the water circulation state,
First chamber a21 of water storage device a2 is connected with pure water mouth a11, and water pump a5 opens, so that water source under the driving of water pump a5
The reverse osmosis membrane apparatus a1 that the water of (tap water) is pressurizeed and then is conveyed in water purifier, the reverse osmosis membrane apparatus in water purifier
The water flowing into from raw water mouth a13 can be become pure water through filtration by a1, and pure water then flows out from pure water mouth a11, and concentrated water is then from dense
Mouth of a river a12 discharges.Because first chamber a21 of water storage device a2 is series at pure water mouth a11 and the user of reverse osmosis membrane apparatus a1
Between water end (W.E.) a10, so the pure water flowing out from reverse osmosis membrane apparatus a1 pure water mouth a11 flows into the first chamber of water storage device a2
A21, due to user with water end (W.E.) a10 in opened condition, pressure is less, and first chamber a21 that pure water flows out water storage device a2 is preferential
Flow to user with water end (W.E.) a10 it is difficult to make the volume of first chamber a21 within water storage device a2 increase, and then be difficult to a large amount of
It is stored in first chamber a21 of water storage device a2.(close) after user is with water end (W.E.) a10 stopping water, water pump a5 will continue
Work a period of time, so that reverse osmosis membrane apparatus a1 can continue to produce pure water；Under the pressure that water pump a5 provides, user simultaneously
It is under closing with water end (W.E.) a10, the pure water flowing out from reverse osmosis membrane apparatus a1 pure water mouth a11 makes the volume of first chamber a21
Increase, to store pure water and then the cleaning for reverse osmosis membrane apparatus a1.When the first chamber a21 volume of water storage device a2 increases
After storage finishes pure water, water purifier can enter cleaning state, under cleaning state, by first chamber a21 of water storage device a2
Disconnect with pure water mouth a11, and first chamber a21 is connected with raw water mouth a13, thus water storage device a2 storage inside is pure
Water is expelled to the raw water mouth a13 of reverse osmosis membrane apparatus a1, and this portion of pure water flows into anti-from the raw water mouth a13 of reverse osmosis membrane apparatus a1
Permeable membrane device a1, and then the reverse osmosis membrane in reverse osmosis membrane apparatus a1 is rinsed, so that the raw water of reverse osmosis membrane
The concentrated water of side is rinsed, and then is replaced by pure water, and the pure water after flushing flows from the concentrated water spout a12 of reverse osmosis membrane apparatus a1
Go out.So, during water purifier is in and does not use, the both sides of reverse osmosis membrane are pure water, in a long time, reverse osmosis membrane
The total dissolved solidss (tds) of pure water side will not uprise.So, when water purifier is again under controlling the water circulation state, this water purifier is opened
The total dissolved solidss (tds) of first glass of pure water that the beginning flows out when using have obtained effective reduction.Fig. 9 be the present invention in water purifier with
The common water purifier without water storage device a2 shuts down total dissolved solidss (tds) comparison diagram of water outlet after a2 hour, as Fig. 9 institute
Show, the total dissolved solidss (tds) of the tap water (raw water) of input are higher, after water purifier shuts down a2 hour, open water purification mechanism
Water, is all reduced by the total dissolved solidss (tds) of pure water after filtering for the water purifier raw water.Just start in water purifier
Interior about the water a30 second, the total dissolved solidss (tds) not possessing the pure water of common water purifier outflow of water storage device a2 are much higher than
The total dissolved solidss (tds) of the pure water that water purifier flows out in the present invention.Can illustrate from this contrast experiment, net in the present invention
Water dispenser effectively reduces water purifier after shutting down a period of time and starts again at the total dissolved solidss (tds) using the pure water flowing out.With
When, first chamber a21 of this water storage device a2 be series at the pure water mouth a11 of reverse osmosis membrane apparatus a1 and user with water end (W.E.) a10 it
Between, so each time from the pure water that reverse osmosis membrane apparatus a1 pure water mouth a11 flows out when reaching user with water end (W.E.) a10, pure water must
First chamber a21 of water storage device a2 must be flowed through, so, the water that can store in first chamber a21 of water storage device a2 is all
Running water, is difficult to pile up the impurity producing in the process of life-time service, first chamber a21 of water storage device a2 or grows thin
Bacterium, so ensure water storage device a2 to reverse osmosis membrane apparatus a1 so that rinse when pure water quality, finally ensure user's water end (W.E.)
The quality of a10 water.Secondly, (close) after user is with water end (W.E.) a10 stopping water, water pump a5 will work on a period of time,
It is used for reverse osmosis membrane with just water storage device a2 is carried out after water with storage with water end (W.E.) a10 stopping by the way and in user
The pure water of device a1 cleaning, due to the limitation of reverse osmosis membrane apparatus a1, the flow itself going out in the unit interval of pure water has
Limit, in the normal state, it also can only meet the requirement of user reluctantly, and much out of patience user can complain its water yield too
Little, fill a cup of the overlong time that water needs to wait, or when water purifier controlling the water circulation starts, ability after needing the time waiting the several seconds
Go out pure water.If when user is with water end (W.E.) a10 water receiving, water storage device a2 is carried out store pure water, then the pure water shunting away
The pure water that user is flowed out with water end (W.E.) a10 can be made less, this will have a strong impact on the experience of user.So in this water purifier
The middle pure water being used for rinsing that stores water storage device a2 is arranged on user with after water end (W.E.) a10 stopping water, so avoiding using
The situation that the water outlet of family water end (W.E.) a10 tails off.
