It is enough accelerated the speed of water processed using the pressure, converts water purification for a part of source water.Made from reverse osmosis purified water unit 6
Water purification can be exported through water outlet 7, such as clear water faucet.
Water flow rate sensor 5 is located at the input side of booster pump 4 in main waterway 10, is able to detect in main waterway 10 and is located at pressurization
The water flow velocity of 4 input side region of pump.Water flow rate sensor 5 is connect with controller 20, to convert electric signal shape for water flow velocity
After the flow velocity signal of formula, which is transmitted to controller 20.Controller 20 is connect with booster pump 4, according to this flow velocity
Signal --- more specifically flow velocity indicated by flow velocity signal controls the working condition of booster pump 4.It is worth noting
, in addition to water flow rate sensor 5 and booster pump 4, controller 20 can also be connected with other equipment.For example, as shown in Figure 2
, electric power needed for controller 20 also connects to power supply and obtains 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.Intake pressure, water purification flow velocity occur fluctuating or reverse osmosis purified water
Situations such as unit 6 blocks leads to the idle running of booster pump 4, generates unnecessary noise.Furthermore booster pump 4 is usually under idle running
The failure rate that operation also results in booster pump 4 increases.
In the reverse osmosis water purifier of the present embodiment, controller 20 can be according to the flow velocity pair before the booster pump in main waterway 10

Under suitable flow velocity.Therefore this embodiment avoids generate under idle running caused by 4 intake pressure of booster pump deficiency or flow velocity deficiency
4 high failure rate of noise and booster pump the problem of.Although one embodiment of reverse osmosis water purifier of the invention institute as above
It states, but in other embodiments of the invention, reverse osmosis water purifier can have in many aspects relative to above-described embodiment
There is the variation of multiplicity.At least part in these variations is illustrated with some embodiments below.
Firstly, the tool that controller 20 controls booster pump 4 according to the flow velocity of 4 input side of booster pump in main waterway 10
Body mode can be multiplicity.With continued reference to Fig. 1 and Fig. 2, in some embodiments, preset flow rate model is stored in controller 20
It encloses.Controller 20 can to receive flow velocity signal and know in main waterway 10 after the flow velocity of 4 input side of booster pump, by flow velocity with
The preset flow rate range being stored in controller 20 is compared.According to this comparison result it may determine that current main waterway
In the normal range whether the flow velocity in 10.On this basis, controller 20 can be controlled according to the result of the judgement and is pressurized
The working condition of pump 4.
Secondly, being also possible to according to the specific method that judging result controls booster pump 4 more after obtaining above-mentioned judging result
Sample.Such as in some embodiments, controller 20 can (hereinafter referred to as flow velocity be different not within the scope of preset flow rate in flow velocity
When often), make 4 low power run of booster pump.Here the low power operating state of booster pump 4 is referred to significantly lower than booster pump 4 just
The often power of water pressurization processed, such as the 10%-20% of normal power.In some embodiments, controller 20 can flow velocity not
Make booster pump 4 out of service when within a preset range.In other words, in these embodiments, controller 20 is only in main water above-mentioned
It when the flow velocity of road booster pump input side is within the scope of preset flow rate, just operates normally booster pump 4, is pressurized water processed.This can be with
It avoids dallying caused by being pressurized the reasons such as pump suction supply pressure deficiency or flow velocity deficiency due to generating unnecessary noise, and due to
The idle running for reducing booster pump reduces the risk of pressurization failure of pump.It is worth noting that, " preset flow rate range " is not necessarily
One numberical range.Preset flow rate range is only a numerical value in some embodiments.
Third, water flow rate sensor 5 is when detecting the flow velocity of the booster pump input side in detection main waterway 10, detection
Any position of the specific location of water flow velocity between water inlet and booster pump 4, therefore water flow rate sensor 5 may be provided at into water
Any position between mouth and booster pump 4.The reason of being arranged in this way is that the working condition of booster pump 4 is mainly by its water inlet end
The influence of water flow velocity.Therefore the water flow velocity of detection 4 front end of booster pump can preferably understand the real work state of booster pump 4.
On the other hand, booster pump 4, which is generally set, has certain corrective action to water flow velocity therethrough.Therefore in booster pump 4
The water flow velocity that water flow outflow end measures tends not to the working condition for being truly reflected booster pump 4.
With reference to Fig. 1 and Fig. 2, in some embodiments, reverse osmosis water purifier also has inlet water solenoid valve 3.Inlet water solenoid valve 3
The input side of booster pump 4 in main waterway 10, the more specifically region between water inlet 1 and booster pump 4 are set.Inlet water solenoid valve
3 connect with controller 20, and can open and close and (disconnect) under the control of controller 20.It is such to be arranged so that one
In a little situations, such as when reverse osmosis purified water unit 6 is out of service, controller 20 can the inlet water solenoid valve 3 close so that source
Water cannot continue through water inlet 1 and enter main waterway 10, stop water processed.
It continues to refer to figure 1 and Fig. 2 has preset flow rate range and can lead in some embodiments in controller 20
After crossing acquisition flow velocity signal, by the water flow velocity of 4 input side of booster pump in the main waterway 10 respectively be stored in controller 20
Preset flow rate range be compared.The water flow velocity of 4 input side of booster pump in current main waterway 10 is judged by comparing result
Whether in the normal range.On this basis, controller 20 can control opening for inlet water solenoid valve 3 according to the comparison result
It opens or closes.For example, controller 20 can flow velocity not within a preset range when make inlet water solenoid valve 3 close.
In an embodiment of the present invention, for controlling booster pump 4 and the preset flow rate range for controlling inlet water solenoid valve 3
It can be identical, be also possible to different.
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 water route 10 is equipped with multiple pretreatment filters 2, multiple pretreatment filter 2 can
To be same or different type.
One or more pretreatment filter 2 may be provided at before booster pump water inlet, with reference to Fig. 1, in some embodiments
In, one or more pretreatment filter 2 is arranged between inlet water solenoid valve 3 and water inlet 1.
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
The maximum spent possibly lower than water outlet 7 goes out water speed.Therefore setting pressure pot 71 can be stored certain by pressure pot 71
Water purification simultaneously maintains certain pressure, ensure that user can use water purification when opening depotition cock, withouts waiting for water processed.
With reference to Fig. 1, in some embodiments, reverse osmosis water purifier also has a waste water water route.It is reflexive on the waste water water route
Infiltration water purification unit 6 starts and is successively arranged wastewater valve 62 and waste water mouth 61.The reason of waste water water route is arranged is, reverse osmosis
During water processed, inorganic salts, heavy metal ion, organic matter in the water of source, colloid, bacterium, virus can not penetrate water purification unit 6
The RO film of reverse osmosis purified water unit 6.Therefore reverse osmosis purified water unit 6 can also produce while the water purification output that will transmit through its RO film
Raw waste water.These waste water need that water purifier is discharged via waste water mouth 61.Wastewater valve 62 can be configured to continue unlatching, so that
It waste water water route can be with small volume exhaust waste water.Intermittent unlatching can also be set in wastewater valve 62, enable waste water water route
Enough waste discharges when wastewater valve 62 is opened.With reference to Fig. 2, in some embodiments, wastewater valve 62 is arranged to according to controller
20 control opens and closes.For example, controller 20 can be such that wastewater valve 62 only opens when reverse osmosis purified water unit 6 carries out water processed
It opens.
In addition to the above-mentioned embodiment about reverse osmosis water purifier, a part of the embodiments of the present invention is about a kind of reverse osmosis
The control method of water purifier.Some embodiments of the control method of reverse osmosis water purifier are illustrated below.With reference to Fig. 3,
In some embodiments, the control method of reverse osmosis water purifier is mainly used for controlling the water purifier in main waterway with booster pump,
The control method of the reverse osmosis water purifier mainly comprises the steps that
In step 301, detection main waterway is located at the water flow velocity in the region of booster pump input side, obtains flow velocity signal.It can
The aforementioned flow velocity of main waterway is detected with water flow rate sensor 5 shown through figure 1 and figure 2, such as water flow velocity switch.
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.Wherein judging whether water outlet is opened can be realized by detecting the state of water outlet.Work as water outlet
When unlatching, user needs using water purification, therefore water purifier should start water processed, and process enters step 303, otherwise rests on step
302。
In step 303, judge whether the flow velocity of detection exceeds preset flow rate range.Exceed preset flow rate range in flow velocity
When water flow velocity exception () in main waterway before booster pump go to step 304.If there is no exceptions for flow velocity, jump to
Step 305.
In step 304, the booster pump of water purifier is made to stop working.In some embodiments, water purifier also has water inlet
Solenoid valve.In these embodiments, the booster pump of water purifier is made to be also turn off the water inlet of reverse osmosis water purifier while stopping working
Solenoid valve.So that when being pressurized air pump inoperative, source water will not continue to enter water purifier for such setting, stop water processed.Some
In embodiment, 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 are then gone to step when water outlet is closed, and close reverse osmosis
The inlet water solenoid valve and booster pump of saturating water purifier.The reason of being arranged in this way is that water outlet closing means that user stops using
Water purification.Water purifier can stop water processed in such cases, therefore can close the booster pump and water inlet electromagnetism of reverse osmosis water purifier
Valve (if any).
Booster pump is the main source of water purifier noise.Intake pressure, flow velocity occur fluctuating or reverse osmosis purified water unit
Situations such as blocking all can cause the water flow velocity of main waterway to change, and then lead to the idle running of booster pump 4, and it is unnecessary to generate
Noise.Furthermore the booster pump failure rate that usually operation under idle running also results in booster pump increases, service life reduction.This implementation
In the control method of reverse osmosis water purifier, due to that booster pump can be made to stop working when water route water flow velocity is abnormal, so
The control method of the reverse osmosis water purifier of the present embodiment can be avoided because booster pump is because of originals such as intake pressure deficiencies or flow velocity deficiency
It dallies caused by due to generates unnecessary noise, simultaneously because reducing the idle running of booster pump, reduce pressurization failure of pump
Risk.
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
