Description

  The present invention relates to an electrolytic ionic water generation method and apparatus for applying a direct current voltage to water to cause a direct current to flow through the water and electrolyzing the water to generate alkali ion water or acidic ion water.

  Such electrolyzed ion water generators are provided in various types and widely used for home use, commercial use, industrial use, and the like. In general, acidic ionized water has a sterilizing action at pH 4 or less, but is not suitable for drinking, whereas alkaline ionized water is suitable for drinking at pH 8 and 9, has a cleaning effect at pH 10 or higher, and is strongly alkaline at pH 12 or higher. Wide range of uses such as sterilization effect. As recognition of the characteristics of these ionic waters has deepened recently, even acidic ionic water returns to normal water when it comes into contact with air or organic matter, so there is a feeling of disinfecting water that is safe and environmentally friendly with no persistence. In addition to sterilization and sterilization with high permeability and exfoliating action due to small clusters, other uses such as face washing, horticulture, deodorization are being developed one after another. On the other hand, strong alkaline ionized water has a strong antioxidant effect and a solvent effect that has a strong dissolving power and takes in soluble components, and is effective in dissolving blood and body fluids as well as dissolving fats and proteins. Specifically, pre-treatment washing of strong acid water, neutralization of strong acid water, hard-to-fall oils and fats on kitchen floors and pet cages, washing of protein stains, and removal of slime that cause fresh fish to be damaged Watering to maintain the freshness of vegetables and cut flowers, promoting the growth of horticultural vegetables and ornamental plants, feeding water for improving meat quality and maintaining health, cleaning dentures, healing athlete's foot, washing lab coats and towels It is used in various ways such as bleaching.

  By the way, strong alkaline ionized water is not suitable for drinking, but as described above, it has excellent properties and a wide range of uses. However, it is difficult to produce strong alkaline ionized water having a pH of 12 or more and a pH of 12.3 or more, and as a device that enables this, an apparatus for continuously performing electrolytic treatment of water in multiple stages using a conventional type of electrolytic ionic water generation method with low efficiency. Has been proposed (see, for example, Patent Documents 1 and 2). The thing of patent document 1 uses raw material water and salt water separately, and salt water is 10% or more, and the production | generation of strong alkaline ionized water is implement | achieved.

Also, a negative electrode chamber passage that snakes along the negative electrode surface between the cathode and the anode arranged across the diaphragm and outside the negative electrode and the positive electrode to generate strongly acidic water, and the positive electrode surface There has also been proposed an apparatus in which a plus electrode chamber meandering along the line is provided, and the minus electrode chamber and the plus electrode chamber are continuously processed through salt water (see, for example, Patent Document 3).
JP-A-8-24865 JP 2001-9453 A JP-A-8-332486

  However, although those described in Patent Documents 1 and 2 can be continuously processed, it is necessary to connect a conventional type of electrolytic ionic water generator in multiple stages in order to obtain strong alkaline ionized water having a pH of 12 or more and a pH of 12.3 or more, Since it is complicated, large and expensive, it is suitable for industrial and commercial large-scale applications but not for small-scale applications such as homes. Moreover, the production efficiency of strong alkaline ionized water is low, and the productivity is not yet sufficient, and the cost of ionized water is increased. When the concentration of salt water is increased to 10% or more like the one described in Patent Document 1, there is a problem that may adversely affect the human body and the natural environment.

Japanese Patent Laid-Open No. 6-246272, which is a patent document 4 different from the above, discloses that the movement speed of H ⁺ between the cathode and the anode is several times faster than the movement speed of OH ⁻ , Since H ⁺ disperses more quickly from the boundary between the anode plate and the water surface, in the distribution of iso-PH lines between the anode plate and the cathode plate, it exists at the boundary between the cathode plate and water and toward the downstream side of the raw water. Compared with the thick layer of strong alkaline water that grows, the strong acidic water layer (PH3 layer) that exists between the anode plate and water is very thin. It is disclosed that it is a cause that becomes lower than the production efficiency of alkaline water. Here, it is considered that the generation efficiency can be increased as the contact area with the electrode on the side where the generation target ion water is obtained to generate strong alkaline water or strong acid water. However, although the thing of patent document 3 can form the contact path of water and an electrode comparatively compactly long, since the production | generation object ionic water side and the non-production | generation object ionic water side are the same contact area ratios, it is the part. Production efficiency is low. In addition, since water contacts the electrode only on one side of the peripheral wall of the meandering meandering passage, the generation efficiency is low also on this surface. Therefore, in order to efficiently produce a large amount of strong alkaline water or strong acidic water, the apparatus must be large and expensive, and the cost of ionic water increases.

  An object of the present invention is to provide an electrolytic ionic water generation method and apparatus capable of generating strong alkaline water having a pH of 12 or more and a pH of 12.3 or more efficiently and at low cost with a simple, small and inexpensive one.

  In order to achieve the above-mentioned object, the electrolytic ionic water generation method of the present invention provides a main electrode while supplying raw water through a water supply pipe made of a main electrode to a main generation chamber partitioned from a by-product chamber by an ion permeable diaphragm. In addition to overflowing through the overflow tube, an electrolyte solution is supplied by supplying a sub-electrode having a polarity different from that of the main electrode to the by-product chamber, and the electrolytic action is caused by energization between the sub-electrode and the main electrode. One feature is that electrolytic ionic water corresponding to the polarity is generated around them, and alkaline or acidic electrolytic ionic water overflowing from the main generation chamber is collected.

  In such a configuration, while the main electrode located in one main generation chamber partitioned by the diaphragm and the sub electrode located in the other sub-generation chamber are energized, both the main and sub-generation chambers are supplied. The raw water to be overflowed is electrolyzed, and alkaline or acidic electrolytic ionic water according to the polarity of the main electrode obtained in the main generation chamber accompanying the flow of ions through the diaphragm can be overflowed and collected as the ionic water to be generated. For this collection, electrolyte is supplied to the by-product chamber and electricity is supplied, and raw water such as ground water and tap water that is not electrolyte solution is supplied to the main product chamber while improving the electrolysis characteristics. Alkaline or acidic electrolyzed ion water containing no electrolysis promoting component is obtained under the component concentration limit. In particular, the water supply pipe for supplying raw water and collecting the overflow of the ionic water to be generated also serves as the main electrode, and at least the entire circumference of the peripheral wall immersed in the supply water is a current-carrying area between the sub electrode. In contact with the raw water and exerting an electrolysis effect, these can take various piping forms and easily increase the pipe density and total pipe length, and the pipe distribution tends to be almost uniform. The area of contact with the raw water is larger in each stage than a plate-like sub-electrode with no piping structure, and it is easy to avoid non-contact bypass of water. Enhanced.

  Such a method includes an electrolytic cell, an ion-permeable diaphragm that partitions the electrolytic cell into a main generation chamber that is supplied with raw water and overflows, and a secondary generation chamber that is supplied with an electrolyte, a main generation chamber, A main electrode and a sub electrode with different polarities arranged in the generation chamber are provided. The main electrode overflows the water supply pipe that supplies raw water into the main generation chamber and the electrolytic ion water generated according to the polarity of the main electrode. This can be achieved by an electrolytic ionic water generating apparatus mainly characterized by being piped as an overflow pipe.

  In addition, an electrolytic cell, an ion permeable diaphragm that partitions the electrolytic cell into a main generation chamber and a secondary generation chamber that are overflowed with raw water and an electrolytic solution chamber that is supplied with an electrolytic solution, a main generation chamber and a by-product A main electrode and a sub-electrode having different polarities arranged in a chamber and energized through an electrolyte between the main electrode and the main electrode. The secondary electrode is piped as an overflow pipe that overflows the electrolytic ion water generated according to the polarity of the water, and the secondary electrode is a water supply pipe that supplies raw water into the secondary generation chamber where it is provided, and the electrolytic that is generated according to the polarity of the secondary electrode. In the electrolytic ionic water generating device, which is another feature of piping as an overflow pipe that overflows ionic water, the main generation chamber and the sub-generation chamber correspond to the difference in polarity of the electrodes arranged in them. Different ion-generated waters, namely alkaline ionized water and acidic ionized water If water is one feature similarly high generation efficiency, obtained simultaneously with production rate.

  The electrolyte uses salt water with a salt concentration of approximately 1 to 2%, so that the production efficiency of alkaline or acidic electrolytic ionic water to be generated is reduced due to insufficient salinity, or the salt content in the production target ionic water is excessive. It is possible to avoid the influence of or the generation of heat. Here, since the electrolytic solution decreases with time and the concentration also changes, it may be replenished periodically so as to adjust this, but it can also be adjusted while being circulated, or it may be poured.

The water supply pipe is positioned at least at the bottom of the chamber in which the water supply pipe is provided, and the overflow pipe is branched or bent into the electrolytic ion water generation area of the chamber in which the water supply pipe is provided and then spread over the electrolytic ion water generation area. In a further configuration, leading to an overflow opening located at
The overflow pipe with branching or bending spread is combined with the water supply pipe, so that it is almost equal to the water in the chamber in which it is installed, that is, almost equal and high pipe density in the main generation chamber and sub-generation chamber. Thus, high contact efficiency without a bypass and a long contact time are secured, and the production of alkaline or acidic electrolytic ionic water to be produced is promoted and stabilized. In addition, when the water supply pipe and the overflow pipe are cathodes, H ⁺ is attracted and diffused as H ₂ gas by reaction with electrons at the cathode, and when it is an anode, OH ⁻ gas is attracted to the anode. The electrons are taken away and become O ₂ gas. In the process of generating electrolytic ionic water in the contact state of the electrode and water as described above, these gas emissions become active rising bubbles extending almost evenly in the water, so one water supply pipe is connected to one water supply port. It becomes a simple water supply system that supplies water to the bottom of the main generation chamber, but the water supply flow is diffused and accompanied by the rising bubbles, and rises while being in close contact with the water supply pipe and overflow pipe. The water generation efficiency is improved, and it can be collected by reaching the height of the overflow outlet of the overflow pipe as high alkaline or acidic electrolytic ionic water with no unevenness and overflowing from the overflow outlet into the overflow pipe. Even in the overflow tube, the ion water to be generated is still generated in the energization region with the sub-electrode, and the degree of alkalinity or acidity is further increased along with its stability. Since the gas to be emitted comes out on the surface of the water, it fills the surface of the water and escapes to the overflow pipe in a sealed environment, so that it is naturally separated from the electrolytic ion water in the middle of the overflow pipe and exhausted.

  According to the sealing of the main production chamber, in particular, all of the diffused gas accumulated in the main generation chamber can be exhausted through a predetermined path without being exhausted by introducing it into the overflow pipe from the overflow opening opened to the liquid surface.

In a further configuration with multiple overflow outlets,
As there are more overflow ports, the lateral flow near the liquid surface can be suppressed, and it is possible to realize uniform and highly efficient generation of electrolytic ionic water without affecting the straight upward flow of the emitted gas. .

In a further configuration, the main electrode is a cathode, and the main generation chamber generates and overflows alkaline ionized water.
Strong alkaline ionized water having a pH of 12 or more and a pH of 12.3 or more can be efficiently and continuously produced in a large amount.

In a further configuration, the main electrode is the anode, and the main generation chamber generates and overflows acidic ion water.
Strong acidic ionized water having a pH of 2 or more and 3 or more can be efficiently and continuously produced in a large amount.

  Further objects and features of the present invention will become apparent from the following detailed description and drawings. Each feature of the present invention can be used alone or in combination in various combinations as much as possible.

  According to the method and apparatus for producing electrolytic ionic water of the present invention, the raw water feed pipe, which is the main electrode in the main production chamber, and the overflow pipe of the electrolytic ionic water are obtained by energizing the sub electrode in the by-product chamber. Due to the unique contact with the generated water and the electrolytic structure, it is possible to efficiently generate alkaline or acidic target ion water according to the polarity of the main electrode. Even alkaline or highly acidic electrolytic ion water is simple, small and inexpensive. Such a device can be obtained with low productivity and low cost, and is suitable for any of small-scale household use, industrial use, and commercial large-scale use.

  By making the salt concentration of the electrolyte used in the by-product chamber to be approximately 1 to 2%, the generation efficiency of the production target ionic water due to insufficient salinity decreases, or the salinity affects the production target ionic water due to excessive salt, It does not generate heat, and a strongly alkaline production target ionic water having a pH of 12 or more and a pH of 12.3 or more, and a pH of 3 or less and 2 or less is obtained with high stability. Moreover, since the obtained electrolytic ionic water is not affected by salt, the alkaline ionic water is particularly friendly to living bodies and the environment, and can be applied to any field without any problems and exhibit its characteristics.

  Hereinafter, with reference to FIG. 1, FIG. 2, embodiment of the electrolytic ionic water production | generation method and apparatus concerning this invention is described, and it uses for an understanding of this invention. The following embodiment is an example embodying the present invention, and does not limit the technical scope of the present invention.

  The electrolytic ionic water generation method of the present embodiment will be described with reference to the electrolytic ionic water generation apparatus schematically shown in FIG. 1. The main generation chamber 21 partitioned from the sub-generation chamber 11 by an ion permeable diaphragm 20. For example, raw water 51 which does not contain salt, such as well water and tap water, is supplied through the water supply pipe 22 which is the main electrode, and overflows as electrolytic ionic water 52 through the overflow pipe 23 which is the main electrode. At the same time, a sub-electrode 12 having a polarity different from that of the main electrode is arranged in the sub-generation chamber 11 and is overflowed as an electrolyte waste water 54 while supplying an electrolytic solution 53 such as salt water. The electrolytic ionic water according to the polarity is generated around them by the electrolysis action by energization between 22 and the overflow pipe 23, and the alkaline or acidic electrolytic ionic water 52 overflowing from the main generation chamber 21 is collected. To.

  As a result of energization when a DC voltage is applied between the main electrode located in one main generation chamber 21 partitioned by the diaphragm 20 and the sub electrode 12 located in the other sub-generation chamber 11, the main, When the raw water 51 and the electrolyte solution 53 that are overflowed while being supplied into the auxiliary generation chambers 21 and 11 are electrolyzed, the alkaline flow according to the polarity of the main electrode obtained in the main generation chamber 21 is accompanied by the movement of ions through the diaphragm 20. Alternatively, acidic electrolytic ionic water 52 can be overflowed and collected as production target ionic water 52. For this collection, as described above, the electrolytic solution 53 such as salt water is supplied to the by-product chamber 11 and the main generation chamber 21 is supplied with the electrolytic solution 53 such as salt water, and the raw water such as ground water or tap water that is not electrolyte solution such as salt water is improved. Since 51 is supplied, alkaline or acidic electrolytic ionic water 52 that does not contain an electrolytic promoting component such as salt is obtained under the concentration limitation of the electrolytic promoting component such as salt in the electrolytic solution 53 in the by-product chamber 11. In particular, the water supply pipe 22 of the raw water 51 and the overflow pipe 23 for collecting the overflow of the production target ion water 52 also serve as the main electrode, and at least the entire circumference of the peripheral wall of the hatched portion immersed in the supply raw water 51 is the sub-surface. The energized region indicated by the oblique lines in FIG. 1 between the electrode 12 and the outer surface comes into contact with the raw water 51 to effect electrolysis, and these water supply pipe 22 and overflow pipe 23 can take various piping forms. Since the pipe density and the total pipe length can be easily increased and the pipe distribution tends to be almost uniform, the contact area with the raw water 51 around the outer peripheral wall of the current-carrying region is larger than that of the plate-like sub-electrode 12 having no pipe structure. In addition to being increased in each stage, it is easy to avoid non-contact bypass of the raw water 51 with respect to the water supply pipe 22 and the overflow pipe 23, so that the production efficiency and production speed of the production target ion water 52 can be increased.

  As a result, in the main generation chamber 21, the raw water supply pipe 22 which is the main electrode and the overflow pipe 23 of the electrolytic ion water 52 are peculiar to water obtained by energizing the sub electrode 12 of the sub-generation chamber 11. Electrolytic ionic water 52, which is an alkaline or acidic generation target according to the polarity of the main electrode, can be efficiently generated by a simple contact and electrolytic structure. Even alkaline and highly acidic electrolytic ionic water 52 is simple, small and inexpensive. And can be obtained at low cost with good productivity and suitable for any of small-scale household use, industrial use, and commercial large-scale use.

  In addition, by making the salt concentration of the electrolytic solution 53 used for the by-product chamber 11 approximately 1 to 2%, the generation target ionic water generation efficiency due to insufficient salt content is reduced, or the generation target ionic water is affected by the salinity. Without generating heat or generating heat, strongly alkaline ionized water having a pH of 12 or more and a pH of 12.3 or more, and a strongly acidic product water of PH3 or less and PH2 or less is obtained. In particular, when the production target ionic water 52 is obtained as strong alkaline electrolytic ionic water using the main electrode as a cathode, it is friendly to the living body and the environment due to the absence of the influence of salt, and can be applied to any field without any problems and exhibit its characteristics. . For example, it is effective for sterilization of foods and the like, and when applied to pre-cleaning before dyeing, it has a high cleaning effect and eliminates uneven coloring due to dirt. Further, since the clusters are small and difficult to evaporate, if used in food, the water retention is good and the storage period can be increased, and the texture is not broken.

  In order to realize such a method, the apparatus shown in the figure includes an electrolytic cell 10, a main production chamber 21 in which raw water 51 is supplied and overflowed in the electrolytic cell 10, and an electrolytic solution 53 that is salt water is supplied and overflowed. In order to provide main electrodes and sub-electrodes having different polarities arranged in the main generation chamber 21 and the sub-generation chamber 11, the main electrode is The water supply pipe 22 that supplies the raw water 51 into the main generation chamber 21 and the overflow pipe 23 that overflows the electrolytic ion water 52 generated according to the polarity of the main electrode are used. Pipes are provided in the water 52 generation area, and the sub-electrodes are the annular or intermittently arranged plate-like sub-electrodes 12 that surround the outer periphery of the main generation chamber 21 in the sub-generation chamber 11. In order to use the main electrode and the sub electrode in a specific pole relationship, one electrode of the DC voltage may be connected to the main electrode, the other electrode may be connected to the sub electrode, and a DC voltage may be applied between them. The main electrode and the sub-electrode are usually connected to the electrode of the voltage application device at a portion above the water surface of the raw water 51 and the electrolytic solution 53, but energization between them occurs below the surface of the raw water 51 and the electrolytic solution 53, That is, it becomes the range which gave the oblique line shown in FIG.

  Here, in order to obtain alkaline ionized water as electrolytic ionic water 52 to be generated, the main electrode may be a cathode and the sub electrode may be an anode. Moreover, what is necessary is just to make a main electrode into an anode in order to obtain acidic ion water as the production | generation object ion water 52. FIG. However, the polarity of the main electrode and the sub electrode can be switched from time to time by using a DC voltage application device capable of switching the polarity. The cathode is not easily corroded and employs stainless steel, which is suitable for the water supply pipe 22 and the overflow pipe 23 when the alkaline ionized water is used as the production target ionized water 52. However, the anode is easily corroded and is resistant to corrosion. High platinum, gold, etc. are suitable, but if maintenance is performed frequently, metal materials with lower costs can be used. The water supply pipe 40 for supplying the electrolytic solution 53, the drain pipe 41 for overflowing the electrolytic solution 53, the electrolytic bath 10 and the like are in contact with the electrolytic solution 53 containing salt, but may not have electrical characteristics, so a resin material such as vinyl chloride is used. That's fine. The diaphragm 20 is preferably made of a ceramic material having a fine porous structure.

  In the example shown in FIG. 1, the water supply pipe 22 has a water supply port 22a located at least at the bottom of the main generation chamber 21, and the overflow pipe 23 branches (or bends) into the electrolytic ionic water generation area and spreads. It is made to reach the overflow port 23a which opens upward and is located on the post-electrolyzed ionic water generation region liquid surface 51a. In this way, the overflow pipe 23 having a bent or expanded shape such as a spiral is combined with the water supply pipe 22, so that it has a substantially uniform and high pipe density in the main generation chamber 21 and the raw water 51. It is possible to ensure high contact efficiency and long contact time that are substantially equal and without bypass, and to promote and stabilize the generation of alkaline or acidic electrolytic ionic water to be generated.

Also, if the water supply pipe 22 and overflow pipe 23 is a cathode is H ⁺ is attracted to it, be dissipated becomes H ₂ gas by reaction with electrons at the cathode, when an anode is it OH ^- gas The electrons are attracted and taken into the anode and diffused as O ₂ gas. In the process of generating electrolytic ionic water in the contact state of the electrode and water as described above, these gases are diffused as active rising bubbles extending almost evenly in the raw water 51, and one water supply pipe 22 supplies one water supply. A simple water supply system that supplies water to the bottom of the main generation chamber 21 from the opening 22a is used, but the water supply flow in such a water supply system rises while being diffused and accompanied by the rising bubbles. Contact efficiency and electrolytic ionic water generation efficiency are also increased by making good contact with the tube 23, and the alkaline ionic water 52 is highly alkaline or acidic with no unevenness at the height of the overflow port 23 a of the overflow tube 23. It can be collected by arriving and overflowing into the overflow pipe 23 from the overflow port 23a. Even in the overflow pipe 23, ion water to be generated is still generated in the energization region with the sub electrode, and the alkalinity or acidity is further increased. The emitted gas exits into the sealed space 55 on the water surface and fills the water surface and escapes to the overflow pipe 23. Therefore, the gas is naturally separated from the electrolytic ionic water 52 through the exhaust pipe 23b connected in the middle of the overflow pipe 23 and exhausted. Be made. Further, all of the diffused gas generated in the main generation chamber 21 due to the sealing is introduced into the overflow pipe 23 from the overflow port 23a that opens to the liquid surface, and can be exhausted through a predetermined route without leaving any excess. That is, contact with carbon dioxide gas can be cut off, and it can be avoided that it reacts with carbon dioxide gas and becomes harmful.

  Here, as in the example shown in FIG. 1, the more the number of overflow ports 23a is, the more the lateral flow in the vicinity of the liquid level is suppressed, and there is no unevenness in eliminating the influence on the straight upward flow of the emitted gas. Highly efficient generation of electrolytic ionic water can be realized.

  In the experiment by the present inventor, in order to generate alkaline ionized water having a pH of 12 or more, the capacity of the conventional apparatus with a power supply of 8 A and 50 V was 2 L / Hr. Hr and productivity increased significantly.

  The electrolytic ionic water generator of the example schematically shown in FIG. 2 is configured to obtain both alkaline ionized water and acidic ionic water at the same time. For this purpose, an ion permeable diaphragm that partitions the electrolytic cell 10 into the main generation chamber 21 and the by-product chamber 11 in which the raw water 51 is supplied and overflows in the electrolytic cell 10 and the electrolytic solution chamber 121 to which the electrolytic solution 53 is supplied. 20 and the main generation chamber 21 and the sub-generation chamber 11, and the main electrode and the sub-electrode having different polarities that are energized through the electrolytic solution 53 between the main generation chamber 21 and the sub-generation chamber 11. The water supply pipe 22 for supplying the raw water 51 into the chamber 21 and the overflow pipe 23 for overflowing the electrolytic ion water 52 generated according to the polarity of the main electrode are piped, and the sub-electrode is the sub-generation chamber 11 in which it is provided. A water supply pipe 122 for supplying the raw water 51 and an overflow pipe 123 for overflowing the electrolytic ion water 152 generated according to the polarity of the sub electrode are provided. As a result, in the main generation chamber 21 and the sub-generation chamber 11, different ion generation waters 52 and 152 corresponding to the difference in polarity of the electrodes arranged on them, that is, alkaline ion water and acidic ion water have one characteristic. In the same way, high production efficiency and production speed can be obtained at the same time. In the illustrated example, the water supply pipe 22 and the overflow pipe 23 which are main electrodes are cathodes, and alkaline ionized water 52 is obtained from the main generation chamber 21, and the water supply pipe 122 and the overflow pipe 123 which are sub electrodes are by-produced as anodes. Acidic ion water 152 is obtained from the chamber 11. The by-product chamber 11, the water supply pipe 122 and its water supply port 122a, the overflow pipe 123 and its overflow port 123a, and the exhaust pipe 123b are respectively the main generation chamber 21, the water supply pipe 22 and its water supply already described in the previous example. The outlet 22a, the overflow pipe 23 and the overflow outlet 23a and the exhaust pipe 23b are provided under common conditions. Note that the water supply pipe 122 and the overflow pipe 123 serving as anodes are eroded by acid from the environment in which acidic ion water is generated, and therefore, those made of titanium and plated with platinum of about 2 μm were used. This improves durability and eliminates adverse effects on the living body even if components are eluted.

  In this embodiment, since the electrolyte solution is not applied as in the previous case, the electrolyte solution decreases with time and the concentration also changes. Do. However, the adjustment can be performed while being circulated, and such a method can also be adopted in the case of the previous example.

  According to the inventor's experiment on this example, the strong alkaline ionized water 52 having a pH of approximately 12 or more, although depending on the temperature adjustment of the ion-generated water, under the conditions that the electrolytic solution 53 has a capacity of 50 L, energization is 130 V, and 8 A It was possible to generate 6 L / Hr each of strongly acidic ionized water 152 having a pH of 2 or less.

  In the present invention, electrolytic alkaline ionized water can be produced efficiently and inexpensively with a simple, small and inexpensive apparatus.
