Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic ion water producing apparatus for producing alkaline ionized water and acidic ionized water as a water purifier for general households and businesses.

[0002]

2. Description of the Related Art Generally, this type of device mainly comprises a water purification device and an electrolyzer connected to a source of raw water, and purifies raw water such as tap water by contacting it with an adsorbent such as activated carbon in the water purification device. After that, send it to the electrolytic cell. When a positive (+) electrode and a negative electrode (-) are energized and a required voltage is applied in the electrolytic cell, (+) ions containing mineral components such as calcium and magnesium gather at the cathode, and H due to electrolysis of water. H ₂ is produced from ⁺ , and OH ⁻ and alkaline ionized water rich in cations are produced. At the same time, the (−) ions gather at the anode, and electrolysis of water produces O ₂ from OH ⁻ and Cl ₂ from Cl ⁻ to produce H ⁺ and acidic ionized water rich in anions. . Alkaline ionized water is suitable for drinking water and cooking as mineral water, and acidic ionized water is unsuitable for drinking water, but it is said to be effective for cleaning and cleaning daily products, face washing and sterilizing water.

FIG. 12 shows an example of a conventional electrolytic cell used in an electrolytic ionized water generator. Raw water such as tap water sent from a supply source is first filtered and purified by a pre-filter and a water purifying device and goes to the electrolytic cell 1. The raw water introduced from the raw water inlet 3 into the electrolysis chamber 4 of the tank body 2 is electrolyzed by applying a voltage between the anode 5 and the cathode 6, and the anode 5 has negative ions and the cathode 6 has positive ions. Collected, PH
The value is acidic on the anode side and alkaline on the cathode side. The cation is an alkaline ionized water containing a mineral component and the outlet 7
From the outlet 8 as anion water.

[0004]

By the way, in such a typical conventional electrolytic cell 1, usually, a pair of parallel anodes 5 and cathodes 6 are disposed on the rear surface of the cell body 2 so as to sandwich the electrolytic chamber 4. Fixed, the anode 5 and the cathode 6 also form part of the electrolysis chamber 4. In other words, raw water is the anode 5 during electrolysis.
The area of contact between the anode 5 and the cathode 6 is limited to the area and the passage time corresponding to the length of the anode 5 and the cathode 6 facing the electrolytic chamber 4.

Therefore, the efficiency of electrolysis is low and the amount of electrolyzed ionic water produced is unsatisfactory. The following measures are generally considered to improve the electrolysis efficiency.

A high voltage is applied between the anode 5 and the cathode 6.

The contact time of raw water is increased by increasing the length of each of the anode 5 and the cathode 6.

However, in the above countermeasures, by increasing the applied voltage, the amounts of O ₂ gas and Cl ₂ gas generated from the anode 5 and H ₂ gas generated from the cathode 6 both increase. Since the generated gas has a characteristic of rising upward in the electrolysis chamber 4, for example, the acidic ionized water generated in the anode 5 of the lower electrode tends to be pulled upward due to this rise. Such acidic ionized water is mixed with the alkaline ionized water generated at the cathode 6 of the upper electrode, which causes a disadvantage that performances such as hydrogen ion concentration (pH) and redox potential of the alkaline ionized water decrease. On the other hand, when the lower electrode is used as the cathode, the performances such as the hydrogen ion concentration (pH) of the acidic ionized water and the oxidation-reduction potential similarly decrease.

Further, as described above, due to the rising characteristics of the generated gas, these gases flood the alkaline ionized water outlet 7 and are collected, and when the outlet 7 is blocked, the resistance of the alkaline ionized water flow is reduced. turn into. Then, the alkaline ionized water on the upper side mixes with the acidic ionized water on the lower side, which deteriorates the performance of the acidic ionized water. This means that as the length of the electrolytic chamber 4 is increased by increasing the length of the anode 5 and the cathode 6, the tendency of the collected gas to block the alkaline ion water outlet 7 increases, and the flow rate of the ion water increases accordingly. Will also decrease, and the above problems will remain. Further, there is also a drawback that a non-electrolytic portion is generated due to the generation of gas and the electrolysis efficiency is lowered.

Therefore, it is an object of the present invention to provide an electrolytic ion water producing apparatus capable of efficiently producing desired ion water while suppressing an increase in size of the electrolytic cell.

[0011]

In order to achieve this object, the electrolytic ionized water generator of claim 1 according to the present invention comprises:
The raw water is introduced into the electrolysis chamber in the electrolysis tank through the raw water inlet, and a voltage is applied between the opposing anode and cathode arranged in the electrolysis chamber to electrolyze the raw water, and the acidic ionized water produced and collected by the anode is collected. In the electrolyzed ion water production device for extracting the alkaline ionized water produced and collected by the cathode from the acidic ionized water outlet and the alkaline ionized water outlet provided at the downstream end of the electrolysis chamber, respectively, below the downstream end of the electrolysis chamber,
One of the desired ones of the alkaline ionized water or the acidic ionized water is provided with a large conduit resistance at the ionized water outlet, and the conduit resistance at the other ionized water outlet is formed to be small so that it is located above the downstream end of the electrolysis chamber. The configuration is characterized by being provided.

According to the present invention, a branch portion is provided at the downstream end of the electrolysis chamber, and the upper passage communicating with one ion water outlet and the lower passage communicating with the other ion water outlet are divided into upper passages.

According to the seventh aspect, the surface area of one electrode on the side facing the upstream side of the electrolytic chamber is made larger than the surface area of the other electrode on the side facing the downstream side.

[0017]

According to the first aspect of the present invention, by applying a voltage between the electrodes, electrolysis of raw water produces O ₂ gas and Cl ₂ gas from the anode and H ₂ gas from the cathode. Generated O ₂ gas,
Both H ₂ gas and Cl ₂ gas have the characteristic of rising above the electrolytic chamber. As the gas rises, the ionic water generated in the lower electrode tends to be pulled upward, and mixes with the ionic water generated in the upper electrode. By utilizing the upward guiding action of ionized water by the generated gas, for example, when the desired ionized water is acidic ionized water, this outlet is arranged on the lower side in the vertical direction. Thereby, even if the lower acidic ionized water is mixed with the upper alkaline ionized water due to the gas induction, the alkaline ionized water is mixed with the acidic ionized water to the minimum.

Further, the conduit resistance at the downstream end on the side where the acidic ionized water is taken out in the electrolysis chamber is increased, while the conduit resistance at the upper alkaline ionized water outlet side is decreased. This allows
The flow rate at the outlet of the alkaline ionized water where the gas accumulates increases, and the gas flows out smoothly. Therefore, the flow path is prevented from being blocked by the gas, the alkaline ionized water is not mixed with the acidic ionized water, the non-electrolytic portion is prevented from being generated, and the deterioration of the electrolysis efficiency can be prevented.

In the case of claims 2 to 5, one upper side passage cross-sectional area divided by the branch portion at the downstream end is larger than the lower side passage cross-sectional area, or the upper side ion water outlet pipe cross-sectional area is set. , Larger than the channel cross-sectional area of the lower ion water outlet, or by providing a control valve capable of proportional control of the valve opening degree in each of the upper and lower ion water outlet pipelines, By providing a difference in the conduit resistance on the lower side, required ion water can be suitably taken out from the outlet on the lower side. Similarly, the resistance of the lower conduit can be increased by facing the back surface of the lower electrode as a return path of the electrolysis chamber and connecting the lower ion water outlet to the downstream end of this return path. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an electrolytic ionized water generator according to the present invention will be described below with reference to the drawings.

FIG. 1 is a sectional view of the first embodiment of the present invention. The cell body of the electrolysis cell 10 has two housing members 11,
12 is liquid-tightly coupled with a bolt 14 via a seal member 13 such as an O-ring. A cavity provided inside the tank body is formed as an electrolysis chamber 16, and the raw water inlet 15 is connected to one end side of the electrolysis chamber 16 and connected to a raw water supply source such as tap water. A water purifier and a pre-filter (not shown) for contacting and purifying the raw water with an adsorbent such as activated carbon are also connected between the raw water inlet 15 and the supply source.

At the downstream end of the electrolytic chamber 16, an upper ion water outlet 17 and a lower ion water outlet 18 according to the present invention are provided so as to open vertically above and below the longitudinal axis of the electrolytic chamber 16. ing.

A pair of parallel electrodes, an anode 20 and a cathode 21, extending in the longitudinal direction are attached to the electrolytic chamber 16.
In the first embodiment, the anode 2 is provided on one housing member 11 side.
0 is fixed, and the cathode 21 is fixed to the other housing member 12. That is, in the first embodiment, the lower electrode according to the present invention is set as the anode 20, and the upper electrode is set as the cathode 21.

Terminals 20a and 21a are provided at the central portions of the rear surfaces of the anode 20 and the cathode 21, respectively, and the terminals 20a and 21a are provided.
The a is inserted through the housing members 11 and 12 as it is, and is connected to the power supply circuit 23 at the outer end portion.

On the other hand, at the downstream end of the electrolysis chamber 16, for example, the upper housing member 12 is utilized to form a pyramidal branch portion 2.
5 are provided so as to project toward the electrolytic chamber 16. The branch portion 25 has slopes 25a with an appropriate inclination gradient on both sides, and the top portion 25b deviates from 1/2 of the width dimension B of the electrolysis chamber 16 by widening the upper side to b ₁ and narrowing the lower side to b ₂ . As a distance.

Therefore, in the first embodiment, the following effects can be obtained by the above configuration.

That is, the raw water sent from the supply source is first filtered and purified by a prefilter, a water purifier, etc.
Head to. The raw water introduced into the electrolysis chamber 16 from the raw water inlet 15 is electrolyzed by applying a voltage between the anode 20 and the cathode 21 which vertically face the electrolysis chamber 16. That is, the anode 20 collects anions and the cathode 21 collects cations. Cations are extracted as alkaline ionized water containing mineral components, and anions are extracted as acidic ionized water.

The ionic water collected in the anode 20 and the cathode 21 is clearly separated by the branch portion 25 at the downstream end of the electrolysis chamber 16, and the acidic ionic water collected in the anode 20 is taken out from the lower outlet 18. . The alkaline ionized water collected in the cathode 21 is taken out from the outlet 17 on the upper side.

Here, as described above, alkaline ionized water is suitable as drinking water and cooking as mineral water, and acidic ionized water is not suitable as drinking water, but is effective for cleaning and cleaning daily products, face washing and sterilizing water. It is said that. Further, in addition to such applications, the present inventors are studying that acidic ionized water is suitable for agricultural water and curing water for golf course turf as long as it has characteristics such as pH value.

Therefore, in the first embodiment, assuming that the acidic ionized water is the desired ionized water which is desired to be efficiently taken out, the outlet 18 for taking out the desired acidic ionized water is set to the lower side. The reason for this is as follows.

There is a degree of difference depending on the level of the voltage depending on the voltage applied between the electrodes.
O ₂ gas and Cl ₂ gas are generated from 0, and H ₂ gas is generated from the cathode 21. Generated O ₂ gas, Cl ₂ gas, H ₂
Both gases have the characteristic of rising above the electrolytic chamber 16. As the gas rises, the ionic water of the lower electrode tends to be pulled upward. Then, the upper ion water mixes with the ion water generated in the lower electrode. For this reason, when the desired ionized water is taken out, it must be below the takeout outlet. That is, when the acidic ionized water is a desired ionized water, the anode 20 is used as the lower portion and the upper electrode is used as the cathode 21, and the outlet 18 for further extracting the acidic ionized water is used.
Should be on the lower side.

Further, in addition to the above, the gas generated at each electrode is collected at the outlet 17 at the upper part, and the outlet 17 is blocked, which becomes a resistance to the flow of the alkaline ionized water, and the alkaline ionized water becomes acidic ionized water. This may cause mixing and further non-electrolytic portions may be generated, which may cause reduction in electrolysis efficiency. Therefore, in this embodiment, the conduit resistance at the downstream end of the electrolysis chamber 16 on the side for taking out acidic ionized water is increased. That is, as shown in FIG. 1, the flow rate is reduced by narrowing the width b ₂ of the lower passage on the side where the acidic ion water is taken out by the branch portion 25 to increase the conduit resistance. On the contrary, since the width b ₁ of the upper passage is wide, the flow rate increases, and the generated O ₂ gas, Cl ₂ gas, and H ₂ gas are discharged from the alkaline ionized water outlet 17 through the upper passage. It In this way, the acidic ionized water can be efficiently taken out from the outlet 18 from the lower passage where the influence of the gas is eliminated.

Since such an effect is obtained, the voltage applied to the anode 20 and the cathode 21 can be relatively low, and the acidic ionized water which is the desired ionized water can be generated despite the low power consumption.

Next, FIG. 2 shows a second embodiment of the present invention. The second embodiment is an embodiment in which the desired ionized water is set to be acidic ionized water.
That is, the diameter d ₁ of the upper alkaline ionized water outlet 17 shown in the first embodiment of FIG. 1 is larger than the diameter d ₂ of the lower acidic ionized water outlet 18 and d ₁ > d _2. is there.
Thereby, the conduit resistance of the acidic ionized water outlet 18 is increased to obtain the same effect as that of the first embodiment. Other structural members are the same as those in the first embodiment of FIG. 1, and corresponding members are designated by the same reference numerals to avoid duplication of description.

FIG. 3 shows a third embodiment of the present invention, and this third embodiment has a structure which should be called a modification of the first embodiment. Similarly, the desired ionized water is set as acidic ionized water. That is, instead of the branch portion 25 shown in the first embodiment of FIG. 1, a plate-like branch portion 26 as shown is provided from the end portion of the upper housing 12 to the electrolytic chamber 16.
Is provided so as to project inward in parallel with the longitudinal axis of the electrolytic chamber 16. Moreover, the plate-like branching portion 26
Is 1/2 the width dimension B of the electrolytic chamber 16 as in the first embodiment.
The distance is larger than that, and the upper side is widened to b ₁ and the lower side is narrowed to b ₂ . Therefore, regarding the obtained action and other structural members, members corresponding to those in FIG.

4 and 5 are a sectional view and a side sectional view taken along line YY of the fourth embodiment of the present invention. In the fourth embodiment, when the electrolytic chamber 16 shown in each of the embodiments of FIGS. 1 to 3 is used as the outward path from the upstream side on the left side to the downstream side on the right side in the drawings, the back surface of the anode 20 which is the lower electrode. Is configured as a return path. That is, between the back surface of the lower anode 20 and the housing member 11, the downstream end of the electrolytic chamber 16 which is the forward path turns around to the back surface of the anode 20 in a rotating manner, and this is formed as the electrolytic chamber 27 of the return path. There is. The acidic ionized water outlet 18 is provided in communication with the downstream end of the electrolytic chamber 27 on the return path. Since the terminal 20a of the anode 20 traverses the electrolytic chamber 27 on the return path, it is protected by an electrical insulating material 28.

Therefore, with this configuration, in this fourth embodiment, the length (area) and time of contact of the raw water with the anode 20 are approximately twice those of the conventional type of the same type, and the length of the electrolytic chamber 16 in the forward path and the length in the return path are the same. It is the sum of the length of the electrolytic chamber 19 and the length. The conduit resistance of the ionized water is increased by that much, and it is smaller than the flow rate of the ionized water on the cathode 21 side that produces the alkaline ionized water on the upper side, and the influence of the acidic ionized water by the generated gas can be avoided.

Further, the anode 20, if increasing the contact area and contact time of the raw water Metropolitan electrolysis efficiency is also improved, in terms of the desired acid ion water, many hydroxyl ions OH in the anode 20 ^-
Are collected and O ₂ is produced by the following electrolytic reaction formula, H ⁺
Is concentrated, so that a low pH value can be produced. Moreover, it is possible to produce satisfactory acidic ionized water by improving the electrolysis efficiency.

Here, the electrolytic reaction at the anode 20 will be described. The introduced raw water was first sent to the electrolytic chamber 16
Then, the surface of the anode 20 is contacted and electrolyzed, and H ₂ O is ionized into H ⁺ and OH ⁻ to cause a reaction represented by the following formula.

2H ₂ O → 4H ⁺ + O ₂ + 4e ⁻ FIG. 6 and FIG. 7 show a fifth embodiment of the present invention. In the fifth embodiment, it is assumed that the branch portion 25 is arranged at the central portion of the width dimension B at the downstream end of the electrolysis chamber 16 based on the first embodiment. In this structure, the control valves 30, 31 that are connected to the upper alkaline ion water outlet 17 and the lower acidic ion water outlet 18 and that can change the flow passage cross-sectional area of each pipe by proportional control Is provided, and the valve openings of the control valves 30 and 31 are controlled by the control signal. Also in this fifth embodiment, when the desired ion water is set to acidic ion water, the control valve 30 for the upper alkaline ion water side conduit and the control valve 31 for the lower acidic ion water side conduit are set. The ratio of the valve opening is not 1: 1, but the valve opening of the lower control valve 31 is narrower than that of the upper control valve 30, that is, the flow rate on the alkaline ion water side is large and the flow rate on the acidic ion water side is large. The conduit resistance is controlled to be large. By performing control in this way, the flow rate of the lower acidic ion water conduit is lower than that of the upper alkaline ion water conduit,
The electrolytic reaction of acidic ionized water can proceed.

On the other hand, FIGS. 8 and 9 show the sixth and sixth aspects of the present invention.
A seventh embodiment is shown. In both of these embodiments, the anode 2
0 and the cathode 21 are divided in the longitudinal direction of these electrodes,
It is a structure in which one and the other that are divided are connected to independent power supply circuits. In both examples, the desired ionized water is also set as acidic ionized water. Other basic structures are common to FIG. 7.

More specifically, in the sixth embodiment of FIG.
It has a structure in which the anode 20 and the cathode 21 are divided in half in the longitudinal direction with an electrical insulating material 32 interposed therebetween. One side of the divided anode 20 is 20A and the other side is 20B. The same applies to the case of the upper cathode 21. Therefore, the divided anode 20A and the cathode 21A on one side form a pair of counter electrodes, and the divided anode 20B and the cathode 21B on the other side form a counter electrode.

The anode 20A and the cathode 21A on one side are connected to the power supply circuit 33, and the anode 20B and the cathode 21B on the other side are connected to the power supply circuit 34, so that the power supply of each counter electrode is independently controlled. There is. In the embodiment, the applied voltage E ₁ between the one side anode 20A and the cathode 21A facing the upstream side of the electrolysis chamber 16 is lower than the applied voltage E ₂ between the other side anode 20B and the cathode 21B facing the downstream side. The voltage of the power supply circuits 33 and 34 is adjusted so that E ₁ <E ₂ is low.

With this configuration, when different voltages are applied to the upstream side and the downstream side of the electrolysis chamber 16, the degree of generation of ionized water by electrolysis of the raw water and gas generation is small on the upstream side and goes to the downstream side. Increase. Anode 2 on the upstream side
Although the electrolysis efficiency is reduced at 0 A and the cathode 21 A, it is more than compensated for by the effect of reducing the influence of the generated gas such as upward induction of the generated ion water. However, the anode 20 on the upstream side
The voltage E ₁ applied between A and the cathode 21A is a voltage value at which electrolysis is performed to the extent that acidic and alkaline ionized water is not mixed with each other, although it is low. Anode 20 on the downstream side
The application of the high voltage E ₂ between B and the cathode 21B enhances the mixing of the ionized water with the generated gas. However, since the branching portion 25 is provided immediately after this, the lower part of the alkaline ionized water is converted into the lower part by the gas induction. Immediately before the acidic ionized water is mixed, it is separated at the branching section 25.

Further, the seventh embodiment shown in FIG. 9 has a structure which can further enhance the operation and effect of the sixth embodiment shown in FIG.

That is, in the seventh embodiment, the upstream counter electrode is formed by the pair of counter electrodes composed of the upstream anode 20A and the cathode 21A and the pair of counter electrodes composed of the downstream anode 20B and the cathode 21B, which are separated from each other. The dividing length is longer than that of the counter electrode on the downstream side. That is, by making the surface areas of the anode 20A and the cathode 21A on the upstream side facing the electrolysis chamber 16 larger than the surface areas of the anode 20B and the cathode 21B on the downstream side, the current density Ad ₁ (A / cm ² ) on the downstream side is It is smaller than that on the downstream side. In this case as well, although there is a decrease in electrolysis efficiency between the anode 20A and the cathode 21A on the upstream side, the influence of the generated gas, such as upward induction of the ion water, is reduced. Similar to the sixth embodiment shown in FIG. 8, this kind of action is nothing but the difference in the flow path resistance and the conduit resistance between the upper side and the lower side of the electrolytic chamber 16 according to the present invention.

Next, FIGS. 10 and 11 are characteristic graphs of the power consumption of the device implemented according to the present invention. As is clear from FIG. 11 showing the correlation between the hydrogen ion concentration (pH) and the power consumption (watt), the device of the present invention shown by the broken line curve has a lower pH value at the same power consumption as compared with the conventional example indicated by the solid line. Is shown. Also,
Hydrogen ion concentration (pH) and throughput per hour (l / m
10), it is understood that the device of the present invention shown by a broken line curve can generate treated water having a low pH value as compared with the conventional example indicated by a solid line.

In the above first to seventh embodiments, the desired ionized water is limited to the acidic ionized water. However, if it is required to take out the alkaline ionized water for drinking water or the like, it can be used as an anode. Switch the cathode vertically and attach it,
The ion water outlet on the lower side in the vertical direction in terms of the rise of the generated gas may be the alkali ion water outlet.

[0050]

As described above, according to the electrolytic ionized water generator of the present invention, in the first aspect, the voltage of the electrodes is applied to electrolyze the raw water so that O ₂ , Cl from the anode and the cathode are discharged. ₂ , the gas such as H ₂ is generated, and the action of inducing the rising of the generated gas to pull up the ionized water generated at the lower electrode is used. In this case, by arranging this outlet on the lower side in the vertical direction and increasing the conduit resistance at the downstream end of the electrolysis chamber on the side where the acidic ion water is taken out, the electrolysis efficiency of the desired ion water can be increased.

In Claims 2 to 7, there are various structures for varying the conduit resistance as claimed in Claim 1, and each of them has a difference in conduit resistance between the upper and lower ion water outlets. Then, the required ionized water can be suitably taken out from the lower outlet.
