Specifically, before the water cleaning systems 100 start water processed, and when first timer detect it is described into When the time interval powered on twice before and after water valve 20 is greater than or equal to the first prefixed time interval, the membrane filter 10 meets default Washing condition, at this time, the controller can trigger the water pump 15, inlet valve 20, the first valve body 25 and the second valve body 35 Control circuit, to control 20 and first valve body 25 of inlet valve to close, while controls second valve body 35 to open, and controls The water pump 15 is opened, to be rinsed to the membrane filter 10, so that being full of raw water in the membrane filter 10.It is thus true The water quality for having protected the first cup pure water produced when starting shooting water processed the next time of water cleaning systems 100 disclosure satisfy that the demand of user；And Rinse the membrane filter 10 to be controlled by the controller and the first timer completely, thus without user's operation, Jin Erfang User use the water cleaning systems 100.
It should be noted that the water cleaning systems 100 are after the power is turned on, water processed can't be carried out at once, usually also need input to make Water instructs or manually opened corresponding component can carry out water processed, that is to say, that the water cleaning systems 100 after the power is turned on, also have One section of standby time, and first timer adjacent time interval for powering on twice before and after the inlet valve 20 is detected is big When prefixed time interval, the controller will trigger the water pump 15, inlet valve 20, the first valve body 25 and The control circuit of two valve bodies 35, to control 20 and first valve body 25 of inlet valve to close, while controls second valve body 35 Open, and control the water pump 15 to open, to be rinsed to the membrane filter 10.So set, on the one hand it ensure that described The waste water of raw water and high concentration in membrane filter 10 is displaced by pure water, and then ensure that the membrane filter 10 start system every time The water quality of the first cup pure water taken can be met the needs of users；On the other hand, the spare time of the water cleaning systems 100 is taken full advantage of Put the time, the flushing process for so allowing for the membrane filter 10 carries out in the case of user is unconscious, and then avoids institute Stating the flushing process of membrane filter 10 influences the water process processed of the water cleaning systems 100.
Further, the water cleaning systems 100 further include respectively with the controller be electrically connected the 3rd valve body 40 and 4th valve body 45；Wherein, the 3rd valve body 40 is installed on the pure water pipe b between the membrane filter 10 and ion exchange filter core 30 On, the pure water pipe b between the water inlet end of the 4th valve body 45 and 10 and the 3rd valve body 40 of membrane filter is connected, and the described 4th The water outlet of valve body 45 is connected with the water inlet end of second valve body 35.It is arranged such so that pure water can pass through the ion Exchange 30 or the 4th valve body 45 of filter core to be back in the membrane filter 10, so avoid the ion exchange filter core 30 1 It is straight in running order, and then be conducive to extend the service life of the ion exchange filter core 30.
Reflux water route in the membrane filter 10 is back in order to facilitate control pure water, and the controller is always according to described the The testing result of one timing controls inlet valve 20, the first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 opening or closing.
Specifically, the controller is used to preset more than or equal to first in the time interval of first timer detection During time interval, the inlet valve 20, the first valve body 25, the second valve body 35, the 3rd valve body 40, the 4th valve body 45 and water are triggered The control circuit of pump 15, to control the inlet valve 20, the first valve body 25 and the 4th valve body 45 to close, while controls described the Two valve bodies 35 and the 3rd valve body 40 are opened, and control the water pump 15 to open.It should be noted that the water cleaning systems 100 If downtime is more than the first prefixed time interval, raw water, waste water and pure water inside the membrane filter 10 can occur double To infiltration, that is to say, that the pure water concentration inside the membrane filter 10 can raise, according to described in the higher pure water rinsing of concentration Membrane filter 10, then need repeatedly to rinse the membrane filter 10, thus extend the flushing duration of the membrane filter 10, And then 100 Pure-water Making of water cleaning systems described in user's normal use can be influenced.And by 25 and the 4th valve body 45 of the first valve body Close, this allows for pure water and is merely able to by being back to again after ion exchange filter core 30 in the membrane filter 10, and pure water is passing through During the ion exchange filter core 30, contained salt ion can be ion exchanged the removing of 30 total number of filter core in pure water, so allow for The pure water water quality being back to inside the membrane filter 10 is relatively good so that reflux pure water circulation can just make institute several times The pure water that composite demand is full of in membrane filter 10 is stated, and then shortens the washing time of the membrane filter 10.
The controller is used to be less than the first prefixed time interval in the time interval of first timer detection, and greatly When the second prefixed time interval, since the water cleaning systems 100 standby time is shorter, between the shorter time Every interior, raw water and waste water in the membrane filter 10 only have less ion to infiltrate into the pure water of the membrane filter 10 even institute Two-way penetration will not be occurred by stating between the raw water in membrane filter 10, waste water and pure water, therefore, can directly use the membrane filtration Pure water in core 10 is rinsed the membrane filter 10, and at this time, the controller triggers the inlet valve 20, the first valve body 25th, the control circuit of the second valve body 35, the 3rd valve body 40, the 4th valve body 45 and water pump 15, to control the inlet valve 20, One valve body 25 and the 3rd valve body 40 are closed, while control 35 and the 4th valve body 45 of the second valve body to open, and described in control Water pump 15 is opened.So set, both ensure that the membrane filter 10 can be quickly rinsed, while the ion can also be avoided It is in running order all the time when the membrane filter 10 rinses to exchange filter core 30, and then effectively extends the membrane filter 10 Service life.
It is worth noting that, the adjacent time powered on twice before and after first timer detects the inlet valve 20 When interval is less than the second prefixed time interval, namely the time interval ratio of the front and rear adjacent water processed twice of the water cleaning systems 100 It is shorter, at this time raw water, waste water and the pure water in the membrane filter 10 can't two-way penetration, at this time, controller control The water pump 15, inlet valve 20, the first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 remain turned-off State, so set, advantageously reducing the waste of water resource.
In an embodiment of the utility model, the detection device is the second timer, and second timer is used for Detect the standby time of the water cleaning systems 100.It should be noted that the standby time of the membrane filter 10 is the membrane filter 10 stop the duration of water processed, and in whole water cleaning systems 100,20 and first valve body 25 of inlet valve is in the water cleaning systems Open mode is in during 100 water processed, is in closed mode when the water cleaning systems 100 stop water processed, that is to say, that can To determine treating for the water cleaning systems 100 by detecting the closing duration of one in 20 and first valve body 25 of inlet valve Machine duration.The controller then according to the testing result of second timer, trigger the inlet valve 20, the first valve body 25, Opening or the closing of second valve body 35, the 3rd valve body 40, the 4th valve body 45 and water pump 15.
Specifically, when second timer detects that the closing duration of the inlet valve 20 reaches the first preset duration When, the controller triggers the control circuit of the inlet valve 20, the first valve body 25, the second valve body 35 and water pump 15, with control Make 20 and first valve body 25 of inlet valve to close, while control second valve body 35 to open, and control the water pump 15 to open Open, to drive the pure water in the membrane filter 10 by being back to again in the membrane filter 10 after the ion exchange filter core 30, To be rinsed to the membrane filter 10, so that being full of pure water in the membrane filter 10.This assures the water purification system The water quality for the first cup pure water produced during the start next time water processed of system 100 disclosure satisfy that the demand of user；And rinse the membrane filter 10 are controlled by the controller and the second timer completely, thus without user's operation, and then institute convenient for users State water cleaning systems 100.
It should be noted that after the membrane filter 10 is rinsed once, pure water, the membrane filter are full of since it is internal Two-way penetration will not occur inside 10, therefore, second timer can detect the water cleaning systems 100 it is standby when It is long reach default standby time after, and will be after detection electric signal be sent to controller, it is possible to be stopped, and described net Next time at the end of water processed, second timer is then turned on water system 100.
In addition, it is necessary to explanation, the preset duration can according to the water quality of 100 territory of use of water cleaning systems come Setting, if the water quality of 100 territory of use of the water cleaning systems is relatively good, first preset duration can set long A bit, when being thus avoided that each water cleaning systems 100 are in holding state, the membrane filter 10 will be rushed The problem of washing occurs；If the water quality of 100 territory of use of water cleaning systems is poor, first preset duration can be set It is shorter, be so on the one hand able to ensure that the water cleaning systems 100 are started shooting the water quality of the first cup pure water produced every time, together When the raw water in the membrane filter 10 and waste water flushing can also be fallen, and then avoid the impurity in the waste water, dirt product The problem of tiring out in the membrane filter 10, and causing the membrane filter 10 to be blocked occurs, and is conducive to extend the membrane filter 10 Service life.
Further, the water cleaning systems 100 further include respectively with the controller be electrically connected the 3rd valve body 40 and 4th valve body 45；Wherein, the 3rd valve body 40 is installed on the pure water pipe b between the membrane filter 10 and ion exchange filter core 30 On, the pure water pipe b between the water inlet end of the 4th valve body 45 and 10 and the 3rd valve body 40 of membrane filter is connected, and the described 4th The water outlet of valve body 45 is connected with the water inlet end of second valve body 35.It is arranged such so that pure water can pass through the ion Exchange 30 or the 4th valve body 45 of filter core to be back in the membrane filter 10, so avoid the ion exchange filter core 30 1 It is straight in running order, and then be conducive to extend the service life of the ion exchange filter core 30.
The reflux water route being back in order to facilitate control pure water in the membrane filter 10, the water cleaning systems 100 further include The first TDS detection probes (not shown) being electrically connected with the controller, the first TDS detection probes are installed on the film In filter core 10, to detect the TDS values of the pure water in the membrane filter 10.The controller is according to second timer and first The testing results of TDS detection probes controls the inlet valve 20, the first valve body 25, the second valve body 35, the 3rd valve body 40 and the The opening of four valve bodies 45 or closing.
Specifically, it is default to detect that the closing duration of the inlet valve 20 is greater than or equal to first in second timer Duration, and when the first TDS detection probes detect that the TDS values of the pure water in the membrane filter 10 are greater than or equal to first During default TDS values, that is to say, that described there occurs two-way penetration between the raw water, waste water and pure water in the membrane filter 10 Pure water higher concentration in membrane filter 10, according to membrane filter 10 described in the higher pure water rinsing of concentration, then needs to described Membrane filter 10 is repeatedly rinsed, and thus extends the flushing duration of the membrane filter 10, and then can be influenced user and normally made With 100 Pure-water Making of water cleaning systems.And be turned off the inlet valve 20, the first valve body 25 and the 4th valve body 45, and Second valve body 35 and the 3rd valve body 40 are opened, this pure water allowed in the membrane filter 10 is merely able to filter by ion exchange Be back to again after core 30 in the membrane filter 10, pure water when by the ion exchange filter core 30, in pure water contained salt from Son can be ion exchanged the removing of 30 total number of filter core, and the pure water water quality for so allowing for being back to inside the membrane filter 10 compares It is good so that reflux pure water circulation can just make the pure water that composite demand is full of in the membrane filter 10 several times, and then Shorten the washing time of the membrane filter 10.
Detect that the closing duration of the inlet valve 20 is greater than or equal to the first preset duration in second timer, and And when the first TDS detection probes detect that the TDS values of the pure water in the membrane filter 10 are less than the first default TDS values, That is, salt ion only less in raw water and waste water in the membrane filter 10 infiltrate into it is pure in the membrane filter 10 In water, or even two-way penetration does not occur between raw water in the membrane filter 10, waste water and pure water, at this time, then can be direct The membrane filter 10 is rinsed using the pure water in the membrane filter 10, i.e., the controller trigger the inlet valve 20, First valve body 25, the second valve body 35, the 3rd valve body 40, the control circuit of the 4th valve body 45 and water pump 15, with control it is described into Water valve 20, the first valve body 25 and the 3rd valve body 40 are closed, while control 35 and the 4th valve body 45 of the second valve body to open, and The water pump 15 is controlled to open.So set, both ensure that the membrane filter 10 can be quickly rinsed, while can also avoid The ion exchange filter core 30 is in running order all the time when the membrane filter 10 rinses, and then effectively extends the film The service life of filter core 10.
Based on the various embodiments described above, it is notable that if before and after the inlet valve 20 twice power-on time it is shorter or If the closing duration of inlet valve 20 described in person is shorter, the water cleaning systems 100 would not rush the membrane filter 10 Wash, and be in the water cleaning systems 100 in the period of holding state, and raw water in the membrane filter 10, waste water with And in the event of two-way penetration between pure water, this will influence the water quality for the first cup pure water that the water cleaning systems 100 are produced, consider To this problem, in an embodiment of the utility model, Fig. 2 is refer to, the water cleaning systems 100 further include and the controller The 2nd TDS detection probes 50 being electrically connected, the 2nd TDS detection probes 50 are installed at the pure water mouth of the membrane filter 10 Or be installed on the pure water pipe b between the water inlet end of the membrane filter 10 and the 4th valve body 45, to detect from the film The TDS values for the pure water that filter core 10 is discharged.The controller is according to controlling the testing result of the 2nd TDS detection probes 50 Opening or the closing of first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45.
It should be noted that when the water cleaning systems 100 are in during water processed, the inlet valve 20 and the water pump 15 are in opening, and this assures have endlessly filtering in the raw water inflow membrane filter 10, and being formed pure Water flows into the pure water pipe b outflows from the pure water mouth of the membrane filter 10.Pure water in the pure water mouth by the membrane filter 10 or During pure water pipe b between the water inlet end of 10 and the 4th valve body 45 of membrane filter described in person, the 2nd TDS detection probes 50 can be to pure The TDS values of water are detected, if the 2nd TDS detection probes 50 detect that the TDS values of pure water are greater than or equal to second and preset During TDS values, the controller triggers the control of first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 Circuit processed, to control 35 and the 4th solenoid valve of the second valve body to close, and controls 25 and the 3rd valve body 40 of the first valve body Open, at this time, after the higher pure water of concentration is by ion exchange filter core 30, then discharged by first valve body 25.Due to pure For water when by the ion exchange filter core 30, contained salt ion can be ion exchanged the removing of 30 total number of filter core in pure water, this Sample allows for be reduced to by the concentration of the pure water of ion exchange filter core 30 meet user demand in the range of, and then ensure that The water cleaning systems 100 first cup pure water produced of starting shooting every time can be met the needs of users.If the 2nd TDS detections are visited When the TDS values of the pure water of first 50 detection are less than the second default TDS values, the water quality for the pure water that the membrane filter 10 is discharged also is indicated that Relatively good, the controller triggers first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 at this time Control circuit, to control 35 and the 3rd valve body 40 of the second valve body, and controls 25 and the 4th solenoid valve of the first valve body to beat Open.The ion exchange filter core 30 is so avoided when the water cleaning systems 100 are in water state processed, all the time in work State, and then can effectively extend the service life of the ion exchange filter core 30.
It should be noted that the first TDS detection probes are with the 2nd TDS detection probes 50, difference lies in institute Stating the first TDS detection probes is worked when the water cleaning systems 100 are in holding state, the 2nd TDS detection probes 50 It is to work in water purification washing during water processed, the two is independent of each other.Also, consider cost problem, the water purification system System 100 can only set a TDS detection probe, need to only set corresponding control circuit to control the TDS detection probes.
Obviously, the 2nd TDS detection probes 50 in above-described embodiment can also be replaced with the 3rd timer (not shown).Tool Body, the 3rd timer is used for the operating time for detecting the water cleaning systems 100.It should be noted that the membrane filter 10 operating time is the water duration processed of the membrane filter 10, in whole water cleaning systems 100,20 and first valve of inlet valve Body 25 is in open mode in 100 water processed of water cleaning systems, is in closing when the water cleaning systems 100 stop water processed Closed state, that is to say, that can determine the water purification system by detecting one in 20 and first valve body 25 of inlet valve The operating time of system 100.The controller then according to the testing result of the 3rd timer, control first valve body 25, Second valve body 35, the 3rd valve body 40 and the 4th valve body 45 are opened or closed.
Specifically, during the water processed of the water cleaning systems 100, and when the work of the 3rd timer detection When length is less than the second preset duration, that is to say, that the water cleaning systems 100 have just started shooting water processed soon, at this time the membrane filter 10 The higher pure water discharge of concentration is inside had, in order to ensure that the pure water of the discharge of water cleaning systems 100 disclosure satisfy that the demand of user, Then need the higher pure water of concentration carrying out desalting processing.The controller is receiving the detection telecommunications of the 3rd timer After number, the control circuit of first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 can be triggered, with control Make 35 and the 4th valve body 45 of the second valve body to close, and control 25 and the 3rd valve body 40 of the first valve body to open, so that The pure water discharged from the membrane filter 10 after ion exchange filter core 30 by resupplying user, since pure water is passing through the ion When exchanging filter core 30, contained salt ion can be ion exchanged the removing of 30 total number of filter core in pure water, so allow for passing through ion In the range of exchanging the concentration of the pure water of filter core 30 and being reduced to and meet user demand, and then it ensure that the water cleaning systems 100 The first cup pure water produced of starting shooting every time can be met the needs of users.
During the water processed of the water cleaning systems 100, and when the operating time of the 3rd timer detection is more than During the second preset duration, at this time, the higher pure water of 10 concentration inside of membrane filter is all discharged, and the pure water newly produced is dense Degree meets user demand, and the controller can trigger described first after the detection electric signal of the 3rd timer is received Valve body 25, the second valve body 35, the control circuit of the 3rd valve body 40 and the 4th valve body 45, to control second valve body 35 and Three valve bodies 40 are closed, and control 25 and the 4th valve body 45 of the first valve body to open, and so avoid the ion exchange filter Core 30 is in running order all the time when the water cleaning systems 100 are in water state processed, so can effectively extend it is described from Son exchanges the service life of filter core 30.
In addition, the 2nd TDS detection probes 50 in above-described embodiment can also be replaced with flowmeter 55.Specifically, please With reference to Fig. 3, the flowmeter 55 is installed on the pure water mouth of the membrane filter 10 or the flowmeter 55 is installed on the membrane filtration On pure water pipe b between the water inlet end of core 10 and the 4th valve body 45, its be used to detecting the water cleaning systems 100 produce it is pure Water.The controller is electrically connected with the flowmeter 55, and the controller is according to the detection knot of the flowmeter 55 Fruit, controls the first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 to open or close.
Specifically, during the water processed of the water cleaning systems 100, and when the flowmeter 55 detects the water purification When the pure water amount that system 100 is produced is less than default pure water amount, that is to say, that the water cleaning systems 100 have just started shooting water processed soon, this The higher pure water discharge of concentration is had in Shi Suoshu membrane filters 10, in order to ensure that the pure water that the water cleaning systems 100 are discharged can Meet the needs of users, then need the higher pure water of concentration carrying out desalting processing.The controller is receiving the flow After the detection electric signal of meter 55, first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 can be triggered Control circuit, to control 35 and the 4th valve body 45 of the second valve body to close, and controls 25 and the 3rd valve body of the first valve body 40 open so that from the membrane filter 10 discharge pure water by resupplying user after ion exchange filter core 30, due to pure water When by the ion exchange filter core 30, contained salt ion can be ion exchanged the removing of 30 total number of filter core in pure water, so In the range of allowing for be reduced to by the concentration of the pure water of ion exchange filter core 30 and meeting user demand, and then it ensure that institute Stating the first cup pure water produced of starting shooting every time of water cleaning systems 100 can meet the needs of users.
During the water processed of the water cleaning systems 100, and when the flowmeter 55 detects the water inlet system system When the pure water amount taken is equal to or more than default pure water amount, that is to say, that higher pure of 10 concentration inside of membrane filter at this time Water is all discharged, and the concentration for the pure water newly produced meets user demand, and the controller is receiving the flowmeter 55 After detecting electric signal, the control electricity of first valve body 25, the second valve body 35, the 3rd valve body 40 and the 4th valve body 45 can be triggered Road, to control 35 and the 3rd valve body 40 of the second valve body to close, and controls 25 and the 4th valve body 45 of the first valve body to open, The ion exchange filter core 30 is so avoided when the water cleaning systems 100 are in water state processed, all the time in work shape State, and then can effectively extend the service life of the ion exchange filter core 30.
