Part and pipeline, those skilled in the art can select suitable arrangement according to the knowledge grasped.
Purifier includes the primary flow path that the part on pipeline and pipeline is collectively formed according to an embodiment of the invention.
In the particular embodiment, primary flow path includes upstream inlet channel 21, booster pump 11, the first pipe section 22, main filtering module
12, second pipe part 23, check valve 13, the 3rd pipe section 24, fluid flow switch 15, the 4th pipe section 26, rearmounted filtering
Module 16 and downstream outlet conduit 27.In upstream, the upstream of inlet channel 21 may include into water inlet and prefilter module
Deng part.Entering water inlet can be connected with water source, and the current from water source come by purifier via primary flow path, and in main mistake
Module 12 is filtered in the embodiment of RO films, part is not discharged through the water of filter membrane via waste water tunnel 25.Through counter-infiltration
The water purification of film flows through primary flow path, and is conveyed to user by pure water inlet (not shown, for example, gooseneck faucet etc.).Purifier
Also include pressure pot 14, its port is connected at the P on the 3rd pipe section 24, alternatively, also carried in examples below
Other optional positions of pressure pot 14 are supplied.In addition, pressure sensor 17 is also disposed on the 3rd pipe section 24.In diagram
In embodiment, pressure sensor 17 is arranged at the slightly downstream of pressure pot 14, alternatively, is additionally provided in examples below
Other optional positions of pressure sensor 17.In addition, purifier also includes analysis and processing module 18, itself and pressure sensor
17, fluid flow switch 15 and booster pump 11 couple.
Pressure pot 14 is known in the art., it is necessary to downstream for the slow main filtering module 12 of water purification
Pressure pot 14 stores water.During discharging water, pressure pot 14 also provides the pressure for promoting current to flow to pure water inlet from pressure pot.
The working method of purifier with pressure pot is substantially：During not discharging water, i.e., during water is not used in user, in compression pump
In the presence of 11, main filtering module 12 water processed, through the filter membrane of main filtering module 12 (for example, reverse osmosis membrane filtration module)
Water purification is slowly accumulated in pressure pot 14 so that the pressure in pressure pot 14 progressively increases, until the saturation of pressure pot 14.Now,
Booster pump 11, which is stopped, makes winner's filtering module 12 stop water processed.During discharging water, pressure pot 14 provides the hydraulic pressure of water outlet.With
Pressure in discharge reduction in pressure pot 14, downstream pressure pot 14 and primary flow path will also be gradually reduced.During discharging water
After the stopping that discharging water, because pressure declines, booster pump 11 reworks, and main filtering module 12 water processed supplements pressure pot again
14.Because main filtering module 12 has a very big pressure drag, the pressure effect in the main downstream of filtering module 12 of 11 pairs of booster pump it is smaller or
It is negligible.Pressure pot generally comprises the air bag inside cavity volume and cavity volume.Increase with the water in cavity volume, air bag is progressively compressed to carry
For bigger pressure.The exemplary embodiments of pressure pot refer to public in Chinese utility model patent disclosed in 20 days January in 2016
U of the number of opening CN 204985695 etc..In being hereby incorporated herein by reference of the patent.In an alternative embodiment, it can also be used
The pressure pot of his structure.
In the prior art, the pressure sensor 17 that the application is used, the location of pressure pot 14 P downstreams are different from
Position on will arrange high-voltage switch gear for control booster pump 11 operation.When high-voltage switch gear detects high-voltage signal, then
Close booster pump 11 and stop water processed, when high-voltage switch gear does not detect high-voltage signal, then booster pump 11 is run and is made
Water.In the prior art there is also such embodiment, which provide the flowmeter in primary flow path to count main filtering module institute
The water purification total amount of filtering, thus calculates the life-span of the filter membrane of main filtering module 12.Prior art is different from, as described below
, this application provides different solutions.
Pressure sensor 17 is provided in this application to substitute high-voltage switch gear and flowmeter.Pressure sensor 17 can be obtained
Take the specific pressure value of pressure pot 14.In certain embodiments, pressure sensor 17 may be provided inside pressure pot, pressure pot
The pressure of direct detection pressure pot 14 is carried out in port or the slightly downstream of pressure pot.In an alternative embodiment, pressure sensor 17 can
It is arranged on the pressure of indirect gain pressure pot on any suitable position between check valve 13 and the pure water inlet 27 of primary flow path
Power, for example, at the 3rd pipe section 24, at the 4th pipe section 26, in rearmounted filtering module 16, the rearmounted downstream of filtering module 16
Deng.Because the part of big flow resistance is not present in the downstream of pressure pot 14, it is believed that the 3rd pipe section 24, the 4th pipe section 26
Pressure is approximately equal to the pressure of pressure pot or the pressure correlation with pressure pot.In addition, the generally stream of rearmounted filtering module 16
Resistance is also smaller, and the pressure in the rearmounted filtering module 16 and rearmounted downstream of filtering module 16 can be also considered as being approximately equal to the pressure of pressure pot
Power or the pressure correlation with pressure pot.In other words, in addition to it directly can obtain the pressure of pressure pot, also can pair with pressure pot pressure
The related pressure data of power suitably correct with the pressure of indirect gain pressure pot 14.Pressure sensor 17 and analyzing and processing mould
Block 18 couples the pressure data of collection feeding back to analysis and processing module 18.On the one hand, the alternative height of pressure sensor 17
Compress switch to provide the signal of control booster pump 11 for analysis and processing module 18.On the other hand, analysis and processing module 18 can basis
The pressure data for the pressure pot 14 that pressure sensor 17 is fed back calculates the use state of main filtering module 12.
Specifically, on the one hand, analysis and processing module can estimate main filtering module 12 by method described below
Water purification total amount.In certain embodiments, analysis and processing module 18 is built-in with the flow velocity of pressure pot to pressure curve, wherein flow velocity
It can be considered the instant water yield of pressure pot.The flow velocity of pressure pot depends on the flow resistance in pressure pot downstream to pressure curve, can pass through
Test to obtain the flow velocity of pressure pot in specific purifier to pressure curve.Analysis and processing module 18 is by means of pressure sensor
To gather pressure versus time relationship curve, and by means of the flow velocity built in it to pressure curve come by Pressure versus Time Curve transform
Into flow velocity to time graph.Pair flow velocity during analysis and processing module can discharge water to pressure pot is integrated to time graph, i.e.,
Instant water yield summation, it follows that pressure pot goes out water inventory, because the water of pressure pot is all from main filtering module, thus may be used
Going out water inventory and calculate the water purification total amount of main filtering module by pressure pot.More specifically, the Pressure versus Time with reference to Fig. 3 is bent
Line, during pressure pot discharges water, i.e. during t0 to t1, the pressure of pressure pot constantly declines.Referring again to Fig. 4, by the pressure in Fig. 3
Flow velocity is converted into time graph to time graph, during t0 to t1, because pressure constantly declines, flow velocity or instant water yield
Also correspondingly constantly decline, the t0 to the curve of t1 parts is integrated, you can learning pressure pot, water outlet is total in the process
Amount.By the water that pressure pot is provided is all from the main filtering module in upstream, the water purification total amount of main filtering module thus can be calculated.
During not discharging water, water purification steps into pressure pot, and pressure pot and pressure downstream will be also stepped up, until pressure pot is full
With.In the pressure pot pressurization, analysis and processing module 18 does not add up the water purification total amount of main filtering module.
Whether to learn pressure pot in the period that discharges water, purifier may also include detecting element.Detecting element is used to obtain
Take whether pressure pot is in the information for the state that discharges water.In the embodiment shown in fig. 1, the fluid flow switch in the downstream of pressure pot 14 is utilized
15 are used as detecting element.Whether fluid flow switch 15 can be sensed on stream has fluid to pass through, and such device is known in the art.By
The part in pressure pot downstream in it there will be fluid by primary flow path during pressure pot 14 discharges water, therefore fluid flow switch will be in pressure pot
Fluid is detected during discharging water to pass through.Fluid flow switch 15 further couple with analysis and processing module 18 with by flow signals send to
Analysis and processing module 18.Analysis and processing module 18 understands whether pressure pot is discharging water by means of fluid flow switch 15.Except will flowing
Switch 15 sets outer close to pressure pot 14, and alternatively, fluid flow switch 15 can also be provided at any appropriate position in the downstream of pressure pot 14
Put, or even may be provided at the depotition cock of user.Fluid flow switch 15 can be based on light to be any, electrically or mechanically or other principles
To detect the device of fluid.In addition, being using another advantage of fluid flow switch 15：The feedack of fluid flow switch 15 can be passed through
To adjust the sample frequency of pressure sensor 17.It should be appreciated that due to the finite capacity of pressure pot, general discharge time can only be held
It is continuous several minutes, such as 5 minutes, 10 minutes etc., and the water time processed may be up to a few hours, as a result, it is desirable to during discharging water
The sample frequency of pressure sensor is improved to obtain more accurately Pressure versus Time curve, and during non-discharge water, pressure sensing
Device can work under relatively low sample frequency.Therefore, analysis and processing module 18 can be set to：Detected in fluid flow switch 15
During fluid is discharged water by period, i.e. pressure pot, to obtain more accurately Pressure versus Time curve, analysis and processing module can be responded
The sample frequency of pressure sensor 17 is improved in the signal of fluid flow switch 15, more sampled points thus can be obtained, so as to obtain
Obtain more accurately Pressure versus Time curve.On the contrary, when fluid flow switch 15 does not feed back flowing information, pressure sensor 17 can be
Worked under relatively low sample frequency.In certain embodiments, coordinate with pressure sensor 17 and fluid flow switch 15, analyze and process mould
Block 18 would know that pressure pot 14 whether there is gas leakage.For example, when fluid flow switch 15 just senses water and flows through or just open, can lead to
The pressure data that over-pressed force snesor 17 is sensed judge the air bag in pressure pot 14 whether gas leakage.In general, just starting
The pressure of pressure pot 14 should be pressure during corresponding to pressure pot saturation when discharging water, if the air bag in pressure pot is let out
Leakage, then the pressure of pressure pot 14 will decline and even go to zero when just starting to discharge water.Therefore, just it can open or press based on fluid flow switch
The pressure data of power bucket just when starting to discharge water judge pressure pot whether leak, more specifically, inferring storage based on pressure data
Water or judged by means of the rate of change of pressure data air bag in pressure pot whether gas leakage.
In certain embodiments, pressure sensor 17 itself can also be used as detecting element.Due to during pressure pot discharges water
The pressure of pressure pot will decline, and during pressure pot water storage, the pressure of pressure pot will rise, and therefore, can be passed by means of pressure
The pressure trend that sensor is sensed judges whether pressure pot is discharging water or in water storage.In such embodiments, equally
Ground, improves the sample frequency of pressure sensor when pressure downward trend can be detected in pressure sensor.
In addition, analysis and processing module 18 pressure data that can be fed back according to pressure sensor 17 controls booster pump 11
Operation.For example, booster pump 11 is closed when the pressure that pressure sensor 17 feeds back is more than predetermined value, it is on the contrary then open booster pump
11。
On the other hand, analysis and processing module 18 can also estimate the water purification of main filtering module 12 by method described below
Speed.As shown in figure 5, for generally, for specific pressure pot 14, pressure therein is substantially linear with its water-holding quantity
Relation.The pressure of pressure pot depends on the performance of pressure pot in itself to water-holding quantity curve, and tool can be obtained by simply testing
The pressure of pressure pot is to water-holding quantity curve in body purifier.In certain embodiments, analysis and processing module 18 is built-in with pressure
The pressure of bucket 14 is to water-holding quantity curve, and the pressure data that analysis and processing module 18 is fed back according to pressure sensor is to extrapolate
State the water-holding quantity of pressure pot, and based on main filtering module water during pressure pot 14 water-holding quantity rate of change it is described to calculate
The water purification speed of main filtering module.
With reference to Fig. 6, the Pressure versus Time curve that main filtering module is in pressure pot under different conditions illustrated therein is.For
For I groups, its for reaction normal condition main filtering module, wherein because the hole of filter membrane is unplugged, thus water purification speed compared with
It hurry up, the pressure increase of pressure pot is very fast.For II groups, it is reacts the main filtering module of attenuation state, wherein due to mistake
The some perforations of filter membrane are blocked, therefore water purification speed declines, and pressure pot pressure increase is slower.For III groups, it reacts eventually
The only main filtering module of state, wherein because multiple holes of filter membrane are blocked, therefore water purification speed is very slow, pressure pot pressure
Increase is very slow, is now contemplated that the filter membrane of more change owner filtering module.
Analysis and processing module can according to the pressure of pressure pot to water-holding quantity curve come to the Pressure versus Time curve shown in Fig. 6
Changed, obtain water-holding quantity to time graph.In water-holding quantity in time graph, the slope of each group model is reaction water-holding quantity
Gather way, namely main filtering module water purification speed.
In certain embodiments, analysis and processing module can also judge main filter module based on the water purification speed of main filtering module
Whether block leaks.Due to will gradually be reduced with the rate of filtration using main filtering module, therefore, in the main filtering module estimated
When water purification speed exceedes setting value, then it is assumed that main filtering module (such as miscellaneous part in filter membrane or main filtering module) is let out
Leakage.
With further reference to Fig. 7, it illustrates the Pressure versus Time curve of pressure pot, wherein there is a1, tri- moulds of a2 and a3
Plan discharges water a little.It may be noted that the pressure of pressure pot drastically declines at discharge water point a1, a2, a3.Analysis and processing module is to these
Data can be readily removable these points when being handled.In addition, from figure 7, it is seen that when the water storage time of pressure pot is than discharging water
Between it is much longer.Therefore, analysis and processing module need to adjust the sample frequency of pressure sensor, to obtain effective number pressure on demand
According to.In addition, analysis and processing module can be using various Principles of Statistics or data model come various to the progress of the pressure data of collection
Processing, analysis etc., to optimize the water purification speed of reckoning and the accuracy of water purification total amount.Water purification speed and water purification obtained by calculating
Total numerical quantity for example can individually or jointly be used for the life-span for judging the filter membrane of main filtering module.For example, purifier
There can be warning light to exceed predetermined value in the water purification total amount of main filtering module, or water purification speed is less than predetermined value, Huo Zhejing
Water inventory exceedes the filter membrane that user's more change owner filtering module is pointed out when predetermined value and water purification speed are less than predetermined value.
