Adopt aforesaid device for producing electrolytic water,, also on following point, leaveing some room for improvement in the practicality though can solve aforementioned problem in the past.
(1) by means of for three groups of silicon controlled rectifier photoelectrical couplers, give and control signal A-C, the control of pH can only be accomplished the control of 7 levels.In the occasion of controlling the pH value of brine electrolysis corresponding to the flow of supplying with the former water in the electrolyzer, continuous variable, can not change corresponding to the variation of flow, to the pH value and suppress especially.
(2) because of using three groups of bidirectional thyristor photoelectrical couplers, so many, the expense rising of part number on the whole.
(3) because of the variable control of the successive that carries out the pH value, so as the phase control circuit (light adjusting circuit etc.) that is used like that, carry out the control of resistance value as adopting potentiometer, even then get control mode, with the insulation of driving circuit also imperative based on the electronic circuit of minicomputer etc.,, then can only use for this reason, increase corresponding to the use part number that can decompose as the surrogate of switch if use common photoelectrical coupler.
The 1st purpose of the present invention provide possess the variable control of successive that can carry out the pH value, also can aforementioned dielectric and the electrolysis voltage of the few cheapness of part number with the device for producing electrolytic water of power supply.
The surface water that comes from river etc. on former water base of pipeline water etc. is that evaporation of seawater becomes rainwater and is immersed in water in the ground.Therefore, the material that comprises in the seawater in evaporative process is sneaked into and is included in the aforementioned former water in evaporation or owing to dispersing.Can imagine the composition that also comprises by strippings such as rocks in the ground.In pipeline water etc., comprise the negatively charged ion of various ions, for example chlorion and sulfate ion etc. of such cause and the positively charged ion of sodium and iron etc.The also interpolation of often knowing is used for germ-resistant chlorine.Chlorion and inferior inferior salt acid ion are separated, generated to the part of the chlorine that is added.These materials also are dissolved in the former water.
The ion that is dissolved in the former water of electrolytic water generating device is switched on as ionogen, give birth to the high alkaline water of pH at cathode compartment, generate the low sour water of pH in the anolyte compartment, but utilize electrolysis, the calcium ion that comprises in former water, for example pipeline water loses electric charge with the different calcium ions that are used for additional calcium interpolation with it, in negative electrode, anolyte compartment's barrier film and cathode compartment water outlet, pile up, hinder the interelectrode energising of yin, yang as lime carbonate and calcium hydroxide.At the state that must use hard water, the dirt settling of counter electrode is more, impels the deterioration of electrode, meanwhile, in life-time service inaccessible water outlet, make the function stop of electrolytic water generating device.
For this reason, before using and make the reversal of poles of the voltage on the electrode that is applied to electrolyzer in the water supply interval, that is to say that having the back washing function carries out electrolysis, anode water can be in cathode compartment, generated and negative electrode water can be in the anolyte compartment, generated, the tart anode water that has generation in aforementioned cathode compartment makes the calcium dissolving of accumulation, in the regeneration electrode surface, prevent the deterioration of electrode, become the withstand prolonged utilization structure.The alkalescence of regulation is not shown in water outlet during this reverse, but because of comprising the dissolved calcium salt, so do not wish to discharge as the water of not wanting.
Electrolytic water generating device shown in the Japanese kokai publication hei 7-828287 communique shown in Figure 10 is made of the valve that has the reverse that applies voltage that utilizes electrode, discharges the incrustation scale water that comprises generation energetically.
That is to say, at the negative electrode water relief outlet 73 that comprises the negative electrode water that discharge generates in electrolyzer 56, discharge the anode water relief outlet 74 of anode water and discharge in the electrolytic water generating device of the draining relief outlet 75 of retained water in the electrolyzer, in electrolyzer 56 dirty, be provided with and have the direction switching valve 76,77,78 that control signal is moved, the electrolytic solution of the incrustation scale after the polarity that comprises electrolyzer 56 is switched, direction of passage switching valve 77 to the 75 side drainings of draining relief outlet, up to pH stabilize to.
Yet this mechanism is not only complicated, so and the draining former state that produces because of with back washing the time discharge uneconomical.
Cell is responsive for the pH reaction, therefore, for example from the pH of the alkaline water of the electrolytic water generating device draining of supplying with beverage, in the time of in the former water supply electrolyzer that will stipulate, in electrolyzer, there is certain electric current to flow and expectation often has the alkaline water discharge of certain pH by indication pH.Yet, because the accumulation of aforementioned calcium, because of mobile energising amount between cathode and anode towards the direction of temporary transient minimizing, so as the pH that is discharged from water that also indicates pH, can be stable with certain water discharge.
The 2nd purpose of the present invention is to utilize the back washing repeat short time cycle in normal operation, prevent electrode deterioration, keep the steady state of electrode surface and work for the stabilization of pH of draining.As previously mentioned, at this moment, in back washing machine in the past, when back washing voltage application, can not use the water of discharging from cathode compartment to cathode and anode, and must this draining of discharging.For this reason, the device economy is low, the present invention is being added in the back washing voltage of the dutycycle of regulation between normal moving cathode and anode of changeing between normal draining on-stream period, and with run well during this period identical, by means of carrying out draining from sun, anolyte compartment respectively, also effectively utilize the draining during the back washing.Therefore, can provide the high continous way electrolytic water generating device of economy that does not discharge this draining.
The present invention will provide, and is certain value by means of being not limited to that supply frequency likens to aforementioned and sky, even when electrolytic water generating device is used in the different place of supply frequency, also can obtain the electrolytic water generating device of the draining of often stable certain pH.
In addition, because the accumulation of aforementioned calcium not only flows into the conductivity degree change of the former water of electrolyzer, and change because of the electrolytic condition of electrolyzer body, even, also be not limited to constantly can obtain alkaline water or the sour water of desired pH so the electric current that will be applied on the electrolyzer becomes constant state.On the other hand, the electrolytic water generating device user mainly offers beverage usefulness with aforementioned alkaline water, because of cell reacts responsive to pH, so can expect constantly to obtain the draining of regulation pH.
For this reason, make spent ion exchange resin etc., remove the specific solvent components that comprises in the former water that flows in the electrolyzer, the stable on one side electric conductivity that flows into the former water in the electrolyzer, during making on one side before using and be applied to the reversal of poles of the voltage on the electrode of electrolyzer in the water supply interval, that is to say, back washing takes place continually and carry out electrolysis, the calcium that dissolving is piled up, in the regeneration electrode surface, prevent the deterioration of electrode, and manage the same electric current that on electrode, continued to flow by specified pH.
Different therewith also have measuring from the conductivity degree of the cathode and anode water of electrolyzer draining and pH etc., the direction of passage switching valve carries out draining with want draining in addition in water port before water port, and the electrolytic water generating device of desired draining only usefully is provided.
For this mensuration is provided, have the current road through on adjacent two metal sheets are set, and, between former electrodes, apply voltage and energising, the determinator that the electric conductivity that flows through the water between former electrodes is measured as electrode.
In the past, in this determinator, for example applying voltage of alternating current measures electric conductivity, split pole takes place in the water of measuring one, because of capacity of decomposition is too good,, produce for the dirt settling of electrode etc. so be difficult in flowing water, adapt to, can not flow through stable electric current between two electrodes, the measured value change can not be used.For addressing these problems, as standby circuit is set in determinator, then become complexity and economy of circuit structure reduces.
The 3rd purpose of the present invention provides for the brine electrolysis that constantly obtains certain pH the determinator that the electric conductivity of the former water of supplying with in the electrolyzer is measured.
For reaching aforementioned the 1st purpose, device for producing electrolytic water of the present invention, utilize barrier film that electrolyzer is separated into cathode compartment and anolyte compartment, and at separately the indoor electrode that is provided with, the electrolysis power that applies the regulation volts DS is set between former electrodes, utilize the energising of aforementioned electric interpolar that the former water of supplying with in the aforementioned electrolyzer is carried out electrolysis, and generation negative electrode water in cathode compartment, in the anolyte compartment, generate anode water, it is characterized in that, this maker comprises the control device that is had the aforementioned volts DS that the phase control circuit of optimizing phase of the bidirectional thyristor of supply transformer primary side of aforementioned power source and this bidirectional thyristor of control forms by insertion, and aforementioned phase control circuit comprises: the flow sensor that responds to the former water of supplying with in aforementioned electrolyzer, the dutycycle translation circuit of the output duty of ratio of this transmitter of conversion, the frequency/voltage translation circuit that the frequency transformation of the output pulse of this dutycycle translation circuit is become corresponding voltage with by the photodiode of the output voltage that responds to this frequency/voltage translation circuit and respond to this generation diode and photoelectrical coupler that the light conduction cell that is connected with aforementioned bidirectional thyristor is formed.
