Within step 306, judge whether water outlet closes.304 can be then gone to step when water outlet is closed, and closed
The inlet water solenoid valve and booster pump of reverse osmosis water purifier.The reason of being arranged in this way is that water outlet closing means that user stops
Use water purification.Water purifier can stop water processed in such cases, therefore can close booster pump and the water inlet of reverse osmosis water purifier
Solenoid valve (if any).
The main reason for water purifier makes a noise is the noise for being pressurized pump operation and generating.If furthermore booster pump is often improper
The failure rate that operation will lead to booster pump under environment increases, service life reduction.The control method of the reverse osmosis water purifier of the present embodiment,
Due to can pressure before being judged as RO film exceed pre-set pressure range when so that booster pump is out of service and closes water inlet electromagnetism
Valve reduces the noise under the improper environment such as such as water purifier intake pressure deficiency or reverse osmosis membrane filter element blocking.Therefore, originally
The control method of the reverse osmosis water purifier of embodiment enables to the mute noise reduction of water purifier, and reduces because of reverse osmosis water purifier
Booster pump failure caused by use under abnormal condition, lasts a long time.
Although one embodiment of the control method of reverse osmosis water purifier of the invention is as described above, still of the invention
In other embodiments, the control method of reverse osmosis water purifier relative to above-described embodiment in many aspects can multiplicity change
Change.For example, can then jump directly to step 304 when water outlet is closed, some other steps can also be jumped to, then
Go to step 304 again.At least part in these variations is illustrated with some embodiments below.
With continued reference to Fig. 3, in some embodiments, water purifier also has the pressure pot that can store water purification.In step 306
In, to when being judged as that water outlet is closed, step 304 is not jumped directly to, but gos to step 307.
In step 307, judge whether water is full in pressure pot.When being judged as in pressure pot that water is not full, step is jumped to
Rapid 305 continue water processed.Then go to step 304 when being judged as that pressure inner bucket water is full, close reverse osmosis water purifier into
Water solenoid valve and booster pump.
The reason of pressure pot is arranged is that the water speed processed of the reverse osmosis purified water unit of water purifier is lower than the water outlet of water outlet
Speed leads to the problem that user is waited with water or water outlet water flow is small, is unable to satisfy the water demand of user.In order to full
There is the water purification of preparation using pressure pot in sufficient user's water demand, reduce user and wait the time of water processed, and be discharged in advance
Flow is big.
Although above scheme allows users to obtain sufficient water purification, as long as user wishes to use only with biggish speed
Water will be persistently using the water purification in pressure pot.Therefore after user terminates with water, the water purification in pressure pot will be not enough to be full of
Pressure pot.In order to so that being full of water purification in pressure pot, water purifier be needed to stop using in user when user next time uses water purification
After water, i.e., after water outlet is closed, continue water processed, and water purification obtained is added in pressure pot, so that pressure pot is as early as possible
Filled so that user can obtain sufficient water purification still in use next time with arbitrary speed.
In some embodiments, can be sentenced by the pressure in the region between booster pump and reverse osmosis purified water unit
Disconnected water outlet whether close and pressure pot whether water is full.If such as judging that pressure is more than preset value, then it is assumed that water outlet is closed
Or pressure pot water is full.
With continued reference to Fig. 3, in some embodiments, in step 307 to when whether water completely judges in pressure pot, if
Judge full for water in pressure pot, do not jump directly to step 304, but first gos to step 308.
In step 308, the pressure in the region to main waterway between booster pump and reverse osmosis purified water unit is sentenced
It is disconnected.The preparation method of pressure can be same or different with the preparation method in step 301.It can be by upper in main waterway
The modes such as the region setting pressure sensor between booster pump and reverse osmosis purified water unit obtain pressure.
If judging, pressure is not above setting value, gos to step and 305 continues water processed, on the contrary then go to step 304,
Close the inlet water solenoid valve and booster pump of reverse osmosis water purifier.Such be provided with is conducive to avoid the hypertonia before RO film, makes
User is obtained when opening water outlet next time, water purification can be obtained with suitable pressure.
It should be noted that the present invention uses pressure pot above with reference to the attached drawing 1-3 embodiment described, but this is only
As an implementation, the embodiment of pressure pot is not equally within protection scope of the present invention.
Although the present invention is disclosed as above with preferred embodiment, it is not for limiting the present invention, any this field skill
Art personnel without departing from the spirit and scope of the present invention, can make possible variation and modification.Therefore, it is all without departing from
The content of technical solution of the present invention, according to the technical essence of the invention any modification to the above embodiments, equivalent variations
And modification, it each falls within the protection scope that the claims in the present invention are defined.
