In the SA1 step, control unit 30 is with reference to having or not valve opening signal to judge whether feed water valve 13a closes.When feed water valve 13a closed, water supply signal generation unit 35 produced a water supply signal or special signal.Control unit 30 is according to the operation of special signal control voltage-regulating circuit 38 and direct supply 40.In this case, water supply signal generation unit 35 is thought a signal generation device.Control unit 30 can be according to the operation of special signal control polarity switching 39.
Under any circumstance, when feed water valve 13a closed, water purification system started antibacterial operation.Proceed to step SA2 from step SA1.At step SA2, the standard polarity voltage application time Ts of preliminary election is set in the timing register 36.Be step SA3 behind the step SA2, in this step, control unit 30 excites direct supply 40 by voltage-regulating circuit 38.As a result, the first volts DS EA1 be applied to second and third electrode 22 and 27 between, therefore, second and third electrode 22 and 27 just respectively as anode and negative electrode.Like this, microorganism and the bacterium that has a faint negative ion just become trapped in the sorbent material part 20.In addition, microorganism on the sorbent material part 20 and the growth of bacterium also are suppressed.In this case, the combination of voltage-regulating circuit 38 and direct supply 40 is called first voltage bringing device.In the process of carrying out the SA3 step, control unit 30 is referred to as first excitation apparatus.
Step SA4 behind step SA3 judges whether the standard polarity voltage application time Ts of preliminary election is over and done with.Over and done with when the standard polarity voltage application time of preliminary election, step SA4 just proceeds to step.SA5 is in the SA5 step, and polarity switching 39 is determined the polarity of the second volts DS EA2, and therefore second electrode 22 and third electrode 27 are respectively as negative electrode and anode.In addition, the opposite polarity voltage application time Tr of preliminary election is set in the timing register 36.Be step SA6 behind the step SA5, in this step, pilot circuit 40 excites direct supply 40 by voltage-regulating circuit 38.As a result, the second volts DS EA2 be applied to second and third electrode 22 and 27 between, therefore second and third electrode 22 and 27 respectively as negative electrode and anode.In this case, the combination of voltage-regulating circuit 38 and direct supply 40 is called second voltage bringing device.In the process of carrying out step SA5, pilot circuit 30 is called second excitation apparatus.The group of first and second excitation apparatus and be called excitation apparatus.
By applying the second volts DS EA2 of opposite polarity,, produce chlorine (hypochlorous acid (HCLO by the chlorion in the former water in third electrode 27 sides -)), to improve the concentration of chlorine.Because third electrode 27 is to be made by above-described material with little chlorine overvoltage, so can produce chlorine efficiently by chlorion.
Be step SA7 after S steps A 6,, judge whether the opposite polarity voltage application time Tr of preliminary election is over and done with in this step.When the over and done with step of the opposite polarity voltage application time Tr of preliminary election just, SA7 turns back to step SA1.
Translate into Fig. 5, describe the variation of cl concn.Here the concentration of supposing chlorion in the former water is 15ppm, and the voltage application time equals 30 seconds.In this case, can obtain the chlorine gas concentration of about 1.0ppm.Be appreciated that when chlorine ion concentration is up to 30ppm the former water that from figure the chlorine gas concentration of about 1.0ppm can obtain in shorter voltage application time.On the contrary, when chlorine ion concentration in the former water hangs down to 10ppm, just need longer voltage application time.Therefore, the opposite polarity voltage application time Tr of preliminary election determines according to the water quality (chlorine ion concentration) of former water.
In the water purification system of this embodiment, when feed water valve 13a closes,, apply first volts DS EA1 of standard polarity and the second volts DS EA2 of opposite polarity by second and third electrode 22 and 27.Therefore, except bacteria resistance function of the prior art, also has the concentration that the function that produces chlorine improves chlorine.Therefore, need chlorine still no longer in addition.
Although control the second volts DS EA2 constant high-voltage value is arranged, such as, be 12V in the present embodiment, it be applied to first and third electrode 21 and 27 between still can produce a constant current value, such as 0.4A.

In a second embodiment, when the supply of former water is interrupted respectively and continued, present the function of sterilizing function and generation chlorine respectively.The content of describing among other operation and first embodiment is similar.
With reference to Fig. 8, the water purification system of third embodiment of the invention is described.Identical part marks with identical reference number, and no longer describes.
Be clear that from Fig. 8 sorbent material part 20 has a cylindrical form interior surface that extends between two axle heads, it extends to form a hollow space in vertical direction.First and second electrodes 21 and 22 are placed on the axle head of sorbent material part 20 respectively.Third electrode 27 is placed on as primary electrode in the hollow space of sorbent material part 20, leaves certain space between them.
In the 3rd embodiment water purification system, sorbent material part 20 comprises an activated carbon fiber part 20a and the 4th electrode 29.Activated carbon fiber part 20a is made cylindrical by the activated carbon fiber with electroconductibility, it has relative axle head, also has the cylindrical form interior surface that extends to form hollow space between axle head.The 4th electrode 29 is positioned at the hollow space of activated carbon fiber part 20a, and it closely contacts with the cylindrical form interior surface of activated carbon fiber part 20a.The internal surface of the 4th electrode 29 and first electrode 21 connects into an integral body, inserts in the hollow space of activated carbon fiber part 20a, facing to third electrode 27, wherein leaves a space.Therefore, the 4th electrode 29 is between the internal surface and third electrode 27 of activated carbon fiber part 20a.
With reference to Fig. 9, the 4th electrode 29 has many discharge orifice 29a on its circumferential edge wall in addition.The discharge orifice 29a of the 4th electrode 29 is flow through in purifying waste water of the activated carbon fiber part of flowing through 20a, flows to third electrode 27.The 4th electrode 29 is regarded a supporting electrode as.
As first, second and third electrode 21,22 and 27, the 4th electrode 29 is made by electro-conductive material, electro-conductive material by scribble platinum, platinum iridium alloy, carbon selectively, mix carbon resin wherein a kind of titanium utmost point of material form, the 4th electrode has a little chlorine overvoltage.
In the antibacterial operation in purification pattern, a volts DS is put on the sorbent material part 20 of injecting former water by first electrode 21 (with the 4th electrode 29) and third electrode 27, suppress the growth of microorganism and bacterium, this point will be described in detail subsequently.On the other hand, in the regeneration mode after purification pattern, a voltage of alternating current is put on sorbent material part 20 by first electrode 21 (with the 4th electrode 29) and second electrode 22, comprise trichloromethane and various organic adsorbent with desorb, with the elimination of micro-organisms and bacterium.Described in first embodiment, purification pattern and regeneration mode hocket with pre-set time interval.
The water purification system of the 3rd embodiment and the control section 30 that analog structure is arranged together with the water purification system shown in Figure 2 of first embodiment.In the following description, the operation of antibacterial operation in the purification pattern and generation chlorine will be described as characteristic.
Timing register 36 is also set the timed interval Tc of preliminary election voltage application time Tv and generation chlorine except the pitch time of setting purification pattern and regeneration mode alternate run.According to mode clearly later on, in the water purification system of the 3rd embodiment, in the timed interval Tc that produces chlorine, can quicken the generation of chlorine.
Voltage-regulating circuit 38 by direct supply 40 first and third electrode 21 and 27 between set the first volts DS EA1, the second volts DS EA2 and the 3rd volts DS EA3.The first volts DS EA1 has the low voltage that enough captures microorganism and bacterium, such as 3V.On the other hand, second with the 3rd volts DS EA2 and EA3 have respectively can electrolysis former water to produce the relative higher voltage of chlorine, such as 12V.The first and the 3rd volts DS EA1 and EA3 are standard polarities.The second volts DS EA2 is an opposite polarity.
Water supply signal generation unit 35 is to be used for producing when feed water valve 13a opens valve opening signal.The water supply signal is sent to control unit 30.CPU31 calculates the number of times that produces the chlorine operation.
With reference to Figure 10 and Figure 11 and Fig. 2, the operation of control section in the antibacterial operation is described.Under the continuous regime of former water supply, first, second that applies and tertiary voltage EA1, EA2 and EA3 are interrupted.Suppose that water purification system operates in the purification pattern.At step SC1, with reference to having or not valve opening signal to judge whether feed water valve 13a closes.13a closes when feed water valve, and step SC1 just carries out step SC2.At step SC2, whether the timed interval Tc of judgement generation chlorine begins to calculate over and done with from the operation of purification pattern.If the timed interval Tc that produces chlorine is not also not in the past, step SC2 just proceeds to step SC3, in this step, the first volts DS EA1 of standard polarity be applied to first and third electrode 21 and 27 between.Here note, standard polarity refer to first and third electrode 21 and 27 respectively as anode and negative electrode.Therefore, microorganism and the bacterium that has a faint negative ion just become trapped in the sorbent material part 20.And microorganism in the sorbent material part 20 and the growth of bacterium also are suppressed.Therefore, antibacterial operation has just been carried out.When carrying out step SC3, the combination of voltage-regulating circuit 38, polarity switching 39 and direct supply 40 is referred to as first voltage bringing device.
After operation in purification pattern begins, when produce chlorine the timed interval, Tc was over and done with the time, step SC2 just proceeds to step SC4.In step SC4, on timing register 36, set preliminary election voltage application time Tv.Be step SC5 behind step SC4, in this step, the crust opposite polarity the second volts DS EA2 be applied to second and third electrode 22 and 27 between.Applying of the second volts DS EA2 of opposite polarity continues to reach preliminary election voltage application time Tv.Step SC6 after step SC5 judges whether over and done with preliminary election voltage application time Tv begins to calculate from applying the second volts DS EA2.Here notice that opposite polarity refers to by first electrode 21 as the 4th electrode 29 of negative electrode and polarity as anodic third electrode 27.By applying the second volts DS EA2,, quicken to produce chlorine (hypochlorous acid (HCLO by the chlorion of the 4th electrode 29 those sides such as 12V -)), to increase chlorine gas concentration.Like this, the operation that produces chlorine has just been carried out effectively.When carrying out step SC5, voltage-regulating circuit 38, polarity switching 39 are called second voltage bringing device with the combination of direct supply 40.
Here, the variation of chlorine gas concentration is to similar together with the content that first embodiment describes with reference to Fig. 5.
Repeat if in opposite polarity, produce the operation of chlorine,, will accumulate scale at the 4th electrode 29 places as negative electrode such as 10 times.Therefore, among the step SC7 after step SC6, calculate the times N 1 that the second volts DS EA2 applies.Among the step SC8 after step SC7, judge whether times N 1 equals 10.If times N 1 equals 10, step SC8 just proceeds to step SC9.In step SC9, judge whether feed water valve 13a closes.If feed water valve 13a closes, step SC9 just carries out step SC10, in this step, judges whether the timed interval Tc that produces chlorine is over and done with.Also do not have in the past if produce the timed interval Tc of chlorine, step SC10 just proceeds to step SC11, in this step, applies the first volts DS EA1 of standard polarity.On the other hand, if it is over and done with to produce the timed interval Tc of chlorine, step SC10 just proceeds to step SC12, in this step, applies the 3rd volts DS EA3 of standard polarity.Especially, polarity switching 39 becomes the 3rd volts DS EA3 to the second volts DS EA2.When carrying out step SC12, the combination of voltage-regulating circuit 38, polarity switching 39 and direct supply 40 is as second voltage bringing device, it is used for applying the 3rd volts DS EA3 between the 4th electrode 29 and third electrode 27, therefore the 4th electrode and third electrode 29 and 27 are just respectively as anode and negative electrode.
After the step SC12 is step SC13, in this step, judges whether over and done with preliminary election voltage application time Tv begins to calculate from applying tertiary voltage EA3.If Tv is over and done with for preliminary election voltage application time, step SC13 just proceeds to step SC14, in this step, calculates the times N 2 that the 3rd volts DS EA3 of standard polarity applies.After the step SC14 is step SC15.In step SC15, judge whether times N 2 equals 5, such as.If times N 2 equals 5, step SC15 just turns back to step SC9.Like this, the disagreeable scale that is accumulated on the 4th electrode 29 has just been removed.
In above-described the 3rd embodiment, the times N 2 that times N 1 that the second volts DS EA2 of opposite polarity applies and the 3rd volts DS EA3 of standard polarity apply equals 10 and 5 respectively.Therefore, the times N 2 of times N 1 to the three volts DS EA3 of the second volts DS EA2 is big.This is because in the antibacterial operation of the first volts DS EA1 by applying standard polarity, and scale is sticking and be accumulated on the third electrode 27.Consider this point, will increase by the times N 1 of the second volts DS EA2, come to remove disagreeable scale from third electrode 27 effectively.Although control the second and the 3rd volts DS EA2 and EA3 higher constant voltage values is arranged, first and third electrode 21 and 27 between also to apply and keep the controllable current value of constant, such as 0.4A.
According to above-described the 3rd embodiment, in each opposite polarity and standard polarity, can both produce chlorine.Therefore can remove the scale on third and fourth electrode 27 and 29 reliably, guarantee that antibacterial and chlorine steady in a long-term produces function.
The 4th electrode 29 is positioned at the inside of sorbent material part 20, produces chlorine between third and fourth electrode 27 and 29.Adopt this structure, can prevent that the sorbent material part 20 of activated carbon is subjected to producing the disadvantageous effect of chlorine.Like this, can prevent that activated carbon part 20 is damaged.
With reference to Figure 12, a fourth embodiment in accordance with the invention is described water purification system.Identical parts are adopted and are denoted by like references.
In the water purification system of the 4th embodiment, the 4th electrode 29 is columniform, and separates with the inner circumferential surface of activated carbon fiber part 20a, leaves an annular space 28 between them.The position that each discharge orifice 29a of the 4th electrode 29 makes and each discharge orifice 27a of third electrode 27 are inconsistent along the position that the radial direction of sorbent material part 20 is made.
Thus much, related several embodiment are described the present invention, concerning those skilled in the art, are easy to implement the present invention according to other variety of way.For example, third and fourth electrode can be by two half-cylindrical electrodes in conjunction with forming.The discharge orifice can be the Any shape except that circular port shown in Figure 9.The valve (end marks) that is opposite to terminal (water tap) can use different valve opening signals.If water purification system is installed in the vending machine, can use from the beverage of the switch signal of selling goods of selling goods of the beverage in the vending machine.In addition, can be placed on flow sensor the downstream of water purification system, detect the flow of purifying waste water.In this case, can use flow detecting signal from flow sensor.Equally, can be placed on pressure transmitter the downstream of water purification system, detect the water flow pressure of purifying waste water.In this case, can use pressure detecting signal from pressure transmitter.
