Some embodiments of reverse osmosis water purifier of the invention are illustrated below.With reference to Fig. 1 and Fig. 2, in the present invention
Some embodiments in, reverse osmosis water purifier includes main waterway 10, controller 20 and voltage or current detector 5.Main waterway 10
It mainly include water inlet 1, booster pump 4, reverse osmosis purified water unit 6 and the water outlet 7 along water (flow) direction setting.Reverse osmosis purified water list
There is reverse osmosis membrane (RO film) in member 6.Water inlet 1 can be connect with water sources such as water taps, to obtain source water to be filtered.
Booster pump 4 can be pressurized the source water from water inlet 1, and pressurized source water is delivered to reverse osmosis purified water unit 6
RO film before.Source water into reverse osmosis purified water unit 6 has certain pressure because of pressurization, so 6 energy of reverse osmosis purified water unit
The speed for enough accelerating water processed using the pressure, converts water purification for a part of source water.Water purification made from reverse osmosis purified water unit 6
It can be exported through water outlet 7, such as clear water faucet.
Voltage or current detector 5 are able to detect the voltage or electric current of booster pump 4.Voltage or current detector 5 and control
Device 20 connects, and the voltage or current signal for the booster pump 4 that will test are transmitted to controller 20.Controller 20 and booster pump 4 connect
It connects, booster pump 4 is controlled according to voltage or current signal.It is worth noting that, except voltage or current detector 5 and pressurization
Outside pump 4, controller 20 can also be connected with other equipment.For example, as shown in Figure 2, controller 20 also connects to power supply simultaneously
Electric power needed for obtaining itself operating from the power supply.
In some embodiments, controller 20 may include one or more hardware processors, such as microcontroller, Wei Chu
Reason device, Reduced Instruction Set Computer (RISC), specific integrated circuit (ASIC), integrate using specific instruction processor (ASIP),
Central processing unit (CPU), graphics processing unit (GPU), physical processing unit (PPU), micro controller unit, at digital signal
Reason device (DSP), advanced risc machine (ARM), programmable logic device (PLD), is able to carry out field programmable gate array (FPGA)
One of any circuit of one or more functions or processor etc. or a variety of combinations.
In some embodiments, computer instruction can be run in controller 20 to realize function required for it.
Booster pump is the main source of water purifier noise.Situations such as fluctuating occurs in intake pressure or RO film blocks is all
The pressure that will lead to main waterway 10 changes, and then leads to the idle running of booster pump 4, generates unnecessary noise.In addition, pressurization
The failure rate that the lower operation of 4 idle running of pump also results in booster pump 4 increases, service life reduction.
When booster pump 4 works in the range on normal load (such as nominal load) or near normal load, electricity
Pressure and/electric current can be in preset threshold range.Booster pump 4 is stifled in such as water purifier intake pressure deficiency or reverse osmosis membrane filter element
When running under the improper environment of plug, load can change and be detached from normal load range, cause its operating voltage or electricity
Rheology, such as increase.In the reverse osmosis water purifier of this implementation, due to being equipped with voltage or current detector 5, so controller 20
The voltage or electric current of the load of reflection booster pump 4 can be understood in time, and according to the voltage of booster pump 4 or electric current to booster pump 4
It is controlled, so the load that can be avoided booster pump 4 is abnormal.Therefore, the reverse osmosis water purifier of the present embodiment can be non-
Mute noise reduction under normal environment, and the booster pump failure rate of the reverse osmosis water purifier of the present embodiment is lower, lasts a long time.
Although one embodiment of reverse osmosis water purifier of the invention is as described above, still in the other embodiment of the present invention
In, reverse osmosis water purifier may have the variation of multiplicity relative to above-described embodiment in many aspects.Below with some implementations
Example is illustrated at least part in these variations.
Firstly, controller 20 can be according to the concrete mode that the voltage or electric current of booster pump 4 control booster pump 4
Multiplicity.With continued reference to Fig. 1 and Fig. 2, in some embodiments, the preset threshold of booster pump 4 is stored in controller 20.In this way
Setting enable controller 20 after knowing the voltage or electric current of booster pump 4 in a manner of collecting voltage or current signal,
The voltage of the booster pump 4 or electric current are compared with the preset threshold being stored in controller 20.The knot compared according to this
Fruit it may determine that current booster pump 4 voltage or electric current whether in the normal range.On this basis, controller 20 can
The working condition (such as operation or out of service) of booster pump 4 is controlled according to the result of the judgement.
Secondly, in the comparison result of the voltage or electric current and the preset threshold being stored in controller 20 that obtain booster pump 4
Afterwards, multiplicity is also possible to according to the specific method that comparison result controls booster pump 4.For example, in some embodiments, controlling
Device 20 can make 4 low power run of booster pump when the voltage or electric current of booster pump 4 is not in preset threshold.Here booster pump 4
Low power operating state refer to the power significantly lower than the normal water processed pressurization of booster pump 4, such as the 10%- of normal power
20%.With continued reference to Fig. 1 and Fig. 2, in some embodiments, controller 20 can booster pump 4 voltage or electric current not pre-
If when in threshold value, for example, the voltage or electric current in booster pump 4 are greater than the upper limit of preset threshold or lower than the lower limit of the preset threshold
When, keep booster pump 4 out of service.Such setting can preferably reduce the probability that reverse osmosis water purifier makes a noise, and make
The failure rate for obtaining booster pump 4 further decreases, and the service life further extends.It is worth noting that, " preset threshold " is a numerical value
Range.In some other embodiments, which only includes the upper limit without including lower limit, and controller 20 is only in booster pump
When 4 voltage or electric current is greater than the upper limit of the preset threshold, control booster pump 4 is out of service.
With reference to Fig. 1, in some embodiments, voltage or current detector 5 are the electric currents for being able to detect the electric current of booster pump 4
Detector, and current signal corresponding with electric current is generated according to the electric current detected, current information is then transmitted to controller
20.The reason of being arranged in this way is, for booster pump 4, controller 20 judges the whether suitable foot of the electric current of booster pump 4
It is enough accurate.Compared to other examples, such as voltage or current detector 5 are the voltage detectings for being able to detect the voltage of booster pump 4
The example of device, using voltage or current detector 5 detect the example of the electric current of booster pump 4 in structure relatively simple cost compared with
It is low, and its precision can also receive.For example, current detector can be the electricity for being able to detect booster pump current signal
Resistance.
With reference to Fig. 1 and Fig. 2, in some embodiments, reverse osmosis water purifier also has inlet water solenoid valve 3.The water inlet electromagnetism
The input side of booster pump 4 in main waterway 10, the more specifically region between water inlet 1 and booster pump 4 is arranged in valve 3.The water inlet
Solenoid valve 3 is connect with controller 20, and can be opened and closed and (be disconnected) under the control of controller 20.Such setting makes
Reverse osmosis purified water unit 6 when stopping working, controller 20 can close the inlet water solenoid valve 3, prevent source water from after
It is continuous that main waterway 10 is entered by water inlet 1, stop water processed.
It continues to refer to figure 1 and Fig. 2 stores preset threshold and can pass through in some embodiments in controller 20
After receiving voltage or current signal, the voltage of the booster pump 4 or electric current are carried out with the preset threshold being stored in controller 20
Compare.On this basis, controller 20 can control opening or closing for inlet water solenoid valve 3 according to comparison result.For example, control
Device 20 can be when the voltage or electric current of booster pump 4 be in preset threshold, i.e., the voltage of booster pump 4 or electric current are default greater than this
The upper limit of threshold value or lower than the preset threshold lower limit when, control inlet water solenoid valve 3 close so that source water does not enter back into water purification
Machine.
It in an embodiment of the present invention, can be with the preset threshold for controlling inlet water solenoid valve 3 for controlling booster pump 4
Be it is identical, be also possible to different.
It is worth noting that, controller 20 can not preset in the voltage or electric current of booster pump 4 in example before
When in threshold value, control booster pump 4 is out of service.This, which represents controller 20, can be set to voltage or electric current in booster pump 4
Control booster pump 4 is out of service when not in preset threshold and closes inlet water solenoid valve 3.Certainly, controller 20 can also be by
It is set as only controlling booster pump 4 when the voltage or electric current of booster pump 4 is not in preset threshold out of service.
With reference to Fig. 1, in some embodiments, one or more pretreatment filter 2 is additionally provided in main waterway 10.This
Or multiple pretreatment filters 2 are either filtering type water purification unit (such as sand stick filter etc.), it is net to be also possible to absorption type
Water unit (such as activated charcoal unit etc.).When main waterway 10 is equipped with multiple pretreatment filters 2, multiple pretreatment filter 2
It can be same or different.
One or more specific location of pretreatment filter 2 in main waterway 10 can be multiplicity.With reference to Fig. 1,
In some embodiments, one or more pretreatment filter 2 is arranged on 3 input side of inlet water solenoid valve, more specifically water inlet electricity
Between magnet valve 3 and water inlet 1.
Many water purifiers are equipped with non-return valve and high-voltage switch gear in its main waterway.The reason of these structures are arranged be, this
A little water purifiers need non-return valve to guarantee not flow backwards in main waterway 10, and high-voltage switch gear is arranged to avoid water-making machine from surprisingly opening
It is dynamic.With reference to Fig. 1, in some embodiments of the invention, do not have non-return valve and high-voltage switch gear in main waterway 10.In these implementations
The reason of capable of not having non-return valve and high-voltage switch gear in example, in main waterway 10, is that, when water outlet 7 is closed, water purification will not
It can be flowed out from water outlet 7, at this time since water purifier is also continuing water processed, so the pressure of main waterway 10 can start to increase.It rises
The pressure of high main waterway 10 can make the load of booster pump 4 increase.Increase since voltage or current detector 5 are able to detect reflection
The voltage or electric current of the load of press pump 4 enable controller 20 to control booster pump when the voltage or electric current of booster pump 4 increase
4.So booster pump 4 will continue to one section of shorter Shi Changhou of work and stop working when water outlet 7 is closed.The pressure meeting of main waterway 10
Reach a pre-set pressure range without it is excessively high (this range can by controller 20 control logic and voltage or electric current examine
Survey the detection cycle of device 5, sensitivity determines).Even if therefore not having non-return valve and high-voltage switch gear, main waterway 10 in main waterway 10
Adverse current will not occur.
With reference to Fig. 1, in some embodiments, reverse osmosis water purifier also has one or more pressure pot 71.The pressure
Bucket 71 is connected to the outlet side of reverse osmosis purified water unit 6, for storing water processed.The connecting portion of the pressure pot 71 and main waterway 10
Between reverse osmosis purified water unit 6 and water outlet 7.The reason of such setting is, the water speed processed of reverse osmosis purified water unit 6

In step 302, judge whether water outlet is opened.This can be executed with controller 20 shown through figure 1 and figure 2
Step and hereafter the step of.The information that wherein whether water outlet is opened can be realized by the methods of the state for detecting water outlet.
When water outlet is opened, it is believed that user needs using water purification, therefore water purifier should start water processed, and process enters step 303, no
Then rest on step 302.
In step 303, whether the voltage or electric current for judging booster pump are in the range of preset threshold.If the electricity of booster pump
Pressure or electric current have exceeded preset threshold, then it is assumed that exception has occurred in the operation of main waterway, can go to step 304 at this time.If
The voltage or electric current of booster pump are without departing from preset threshold, then it is assumed that water purifier is working properly, can continue water processed and jump
To step 305.
In step 304, booster pump is made to stop working.Such setting enables to booster pump will not be in main waterway pressure
It works in abnormal situation.
In some embodiments, reverse osmosis water purifier also has inlet water solenoid valve.In these embodiments, the step for
In inlet water solenoid valve can also be made to close.This not enter back into water purifier in pressurization air pump inoperative Shi Yuanshui, stops water processed.?
In some embodiments, the booster pump low power run of water purifier can be made.
In step 305, water purifier works normally, and carries out water processed, is water purification by source Water warfare.
Within step 306, judge whether water outlet closes.304 can be then gone to step when water outlet is closed, and made net
The booster pump of water dispenser is out of service.When water purifier has inlet water solenoid valve, the water inlet electricity of reverse osmosis water purifier can also be closed
Magnet valve.The reason of being arranged in this way is that water outlet closing means that user stops using water purification.Water purifier can be in such cases
Stop water processed, therefore the booster pump and inlet water solenoid valve (if any) of reverse osmosis water purifier can be closed.
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 that can obtain the voltage of the load of reflection booster pump or electric current and indirectly be sentenced according to the voltage of booster pump or size of current
Disconnected main waterway operating condition, so can be when the voltage or electric current of main waterway exceed normal range (NR), so that booster pump stops work
Make and close inlet water solenoid valve, reduces in the improper environment such as such as water purifier intake pressure deficiency or reverse osmosis membrane filter element blocking
Under noise.Therefore, the control method of the reverse osmosis water purifier of the present embodiment enables to the mute noise reduction of water purifier, and reduces
Because reverse osmosis water purifier booster pump under abnormal condition failure caused by use, last 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, within step 306, when water outlet is closed, do not jump directly to walk
Rapid 300304 but go to step 307.
In step 307, judge whether water is full in pressure pot.When water is not full in pressure pot, go to step 305 after
It is continuous to carry out water processed.It then gos to step 304 when pressure inner bucket water is full, closes the booster pump and water inlet electromagnetism of reverse osmosis water purifier
Valve (if any).
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.
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, judge voltage or electric current judge whether voltage or electric current are more than preset threshold.Voltage
Or the preparation method of electric current can be same or different with the preparation method in step 301.It can be shown through figure 1 and figure 2
Voltage or current detector 5 detect the voltage or electric current of booster pump.
When voltage or electric current are no more than preset threshold, then go to step and 305 continue water processed, and then make the pressure of main waterway
Power increases；It is on the contrary then go to step 304, close the booster pump and inlet water solenoid valve (if any) of reverse osmosis water purifier.
