The present invention relates to an electrolytic hydrogen water generating device that generates hydrogen water by dissolving hydrogen gas generated by electrolysis in raw water.

Conventionally, an electrolytic hydrogen water generator as shown in FIG. 4 is known. This conventional apparatus 51 is comprised from the electric power receiving part 52 and the power feeding part 53. As shown in FIG. The water receiving part 52 is provided with the electrolytic container 54 which stores the raw water 50. Inside the electrolytic vessel 54, a cylindrical metal electrode 55 and a cylindrical activated carbon porous body 56 are coaxially accommodated through a several mm annular gap 57. The electrolytic voltage of DC is applied from the power supply part 53 to both electrodes with the metal electrode 55 as a cathode, the conductive activated carbon porous body 56 as an anode, or both polarities reversed.

By this electrolytic voltage, the raw water 50 of the annular gap 57 is electrolyzed, oxygen gas 58 is generated at the anode, hydrogen gas 59 is generated at the cathode, and these electrolytic gases are electrolyzed. Stay on top of the vessel 54. When the internal pressure of the electrolytic vessel 54 rises due to the pressure of the electrolytic gas, the raw water 50 and the electrolytic gas penetrate in from the outside of the activated carbon porous body 56 and seep out through the through hole 60 in the center portion. At this time, the surplus raw water 50 and the electrolytic gas are discharged out of the discharge port 69 to the outside, and the inside of the electrolytic container 54 is maintained at almost atmospheric pressure.

As shown in FIG. 5, the activated carbon porous body 56 is formed into a hollow columnar shape by combining the activated carbon particles 61 with a binder 62. In this porous body 56, there are a myriad of small spaces composed of micropores (micropores) 63 of activated carbon particles 61 and gaps 64 of adjacent activated carbon particles 61. If the electrolysis is continued, the electrolytic gas is filled inside the electrolytic vessel 54, and the electrolytic gas is filled into the activated carbon porous body 56 by this gas pressure and stored in a myriad of small spaces.

In this state, when the water supply valve 65 is opened, the raw water 50 is introduced into the electrolytic vessel 54 and bubbles of the electrolytic gas in the process of flowing through the channel 66 of the activated carbon porous body 56. Suction 67 is sucked, hydrogen gas is mixed and dissolved, and hydrogen water 68 is produced. This hydrogen water 68 is taken out from the discharge port 69 to the outside of the electrolytic container 54 by the water supply pressure of the raw water 50, and is used as drinking water, skin care water, or the like.

Most of the conventional electrolytic hydrogen water generators follow the basic technique of the above-described conventional apparatus 51. For example, Patent Document 1 discloses an activated carbon porous body inside a conductive cylindrical body through a ring-shaped gap. A technique is described in which electrolysis of raw water in an annular gap is applied by receiving a cylindrical body as a cathode and a porous body as an anode, and applying a DC voltage between both electrodes. Patent Literature 2 describes a technique for forming a cyclic gap between a pair of activated carbon porous bodies inside and outside, applying an alternating voltage of 50 to 60 Hz to both porous bodies, and electrolyzing raw water in the cyclic gap.

(Patent Document 2) Japanese Patent Application Laid-Open No. 2003-113488

By the way, according to the conventional apparatus 51, there existed the following problems.

(1) The interior of the electrolytic vessel 54 also serves as an electrolytic chamber using the metal electrode 55 and the activated carbon porous body 56 as an electrode, and a purification chamber made of the activated carbon porous body 56, and in particular, an activated carbon porous body ( By using 56 as an electrode, there were the following problems.

Since the metal electrode 55 and the activated carbon porous body 56 having a large surface area are used for the electrode, the voltage drop due to the resistance of the raw water 50 is large, resulting in poor electrolytic efficiency.

In order to increase the electrolytic efficiency, when the current density is increased, the surface of the activated carbon porous body 56 is modified to easily change electrical characteristics.

Since a direct current voltage is used for the electrolytic voltage, calcium carbonate is generated from the calcium dissolved in the raw water 50 and precipitated on the surface of the negative electrode, which adversely affects the electrolytic efficiency or adheres to the activated carbon porous body 56. This may adversely affect the filtration performance.

For this reason, maintenance work which regularly washes an electrode and removes calcium carbonate using acidic chemicals (for example, citric acid etc.) is necessary.

In addition, when the electrolytic current value is increased, calcium carbonate is easily generated, so it is necessary to perform electrolysis over a long time with a weak current of 200 mA or less, and it is difficult to generate a large amount of hydrogen gas in a short time.

(2) In the example where the application method of the voltage to the electrode was studied, there was the following problem.                         

In the hydrogen water generating apparatus of the electrolysis method which performs electrolysis only when supplying raw water, a countermeasure for changing the polarity of the electrode may be taken every time raw water is supplied. In this case, since supply time is different each time, either electrode may be used. Polarity is deviated and production of calcium carbonate is inevitable.

According to the technique of Patent Document 2, since an alternating voltage is applied to a pair of activated carbon porous bodies, the polarity of the electrode can be periodically changed to suppress the production of calcium carbonate. However, at a commercial frequency of 50 to 60 Hz, since the polarity changes in a short time, the electrolytic efficiency is lowered compared to the DC voltage (see paragraph 0032 of the document).

Since a constant voltage power source is used for direct current and alternating current, the electrolytic current fluctuates greatly due to changes in the water quality of raw water, for example, hardness, chlorine concentration, salt, etc., and there is a problem in stability of electrolysis.

(3) Since the inside of the electrolytic vessel 54 is maintained at almost normal pressure (atmospheric pressure), the storage amount of the electrolytic gas to the activated carbon porous body 56 is small, the dissolved hydrogen concentration of the hydrogen water is low, and as the hydrogen water 68 Short supply time

(4) In terms of the raw water purification function, in general, the size of the microorganisms is several micrometers or less, whereas the micropore diameter of the activated carbon porous body 56 is several ten micrometers, so that the conventional apparatus 51 has sufficient microorganisms. Removal performance is not obtained. In addition, organic matter adsorbed on the activated carbon porous body 56 may promote the growth of microorganisms, and a large amount of microorganisms may be mixed in the hydrogen water 68.

SUMMARY OF THE INVENTION The main object of the present invention is to provide an electrolytic hydrogen water generating apparatus which solves the above problems, can stably supply high concentration hydrogen water for a long time, and hardly adhere calcium carbonate to the activated carbon porous body.

In order to solve the above problems, the electrolytic hydrogen water generator of the present invention is an apparatus for producing hydrogen water by dissolving hydrogen gas generated by electrolysis in raw water, the electrolysis housed in a low water container and the low water container. A supply electrode for applying an electrolytic voltage to the electrolytic electrode, the electrolytic electrode, and the low water container, which are spaced apart from the electrolytic electrode and extended from an upper end of the electrolytic electrode, to which the electrolytic voltage is not applied. Activated carbon porous body, activated carbon porous body whose upper level of activated carbon porous body 12 is higher than the upper level of electrolytic electrode 11, a water supply unit for supplying raw water of predetermined water pressure to the low water container, and the low water container It is characterized by including a water intake unit for taking out the hydrogen water from.

Here, the distance between the electrode for electrolysis and the activated carbon porous body (more specifically, the surface effective for adsorption and occlusion) does not exceed 100 mm in the left and right directions at the shortest part (more preferably, does not exceed 50 mm). It is preferable to approach them both in a vertical direction so as not to exceed 100 mm (more preferably not more than 50 mm), and to make the hydrogen gas generated from the electrolytic electrode start to float and immediately contact the surface of the activated carbon porous body. . Moreover, when the separation distance becomes 10-100 mm from the shortest part to the left-right direction, it is preferable to provide the inclined guide plate which guides hydrogen gas obliquely upward to an activated carbon porous body from an electrode for electrolysis.

Since the hydrogen gas generated at the electrode for electrolysis is very fine when it starts to float, it is easy to be adsorbed to the activated carbon porous body. Thus, when the electrolytic electrode and the activated carbon porous body are brought to the above separation distance, most of the very fine hydrogen gas in the early stage of floating can be adsorbed to the activated carbon porous body.

In addition, the electrolytic chamber in which the electrode for electrolysis is accommodated in a low water container can be installed separately in the lower side, and the water purification chamber in which the activated carbon porous body is accommodated in the upper side, respectively. In this case, by placing the surface of the activated carbon porous body in the longitudinal direction almost immediately above the electrode for electrolysis, the floating hydrogen gas is easily in contact with the surface of the activated carbon porous body. Alternatively, the electrolytic chamber in which the electrolytic electrode is accommodated may be overlapped in the lower portion of the water purification chamber in which the activated carbon porous body is accommodated, thereby allowing the electrolytic electrode and the activated carbon porous body to approach as described above.

If the electrolytic chamber contains electrolytic electrodes of pairs (including the case of switching to an extremely low frequency as described below), and the reservoir is not used as one electrode, the material of the reservoir The metal is not particularly limited, and may be a metal such as stainless steel or aluminum, or a synthetic resin. Although the structure of a low water container is not specifically limited, The pressure resistant structure which can withstand water supply pressure of raw water sufficiently is preferable.

As the electrolytic electrode, for example, an electrode having a metal plating excellent in corrosion resistance of a platinum system can be used. In the present invention, raw water is electrolyzed by an exclusive electrode for electrolysis in the electrolytic chamber without using an activated carbon porous body as the electrode for electrolysis. For this reason, the current density can be increased by using an electrolytic electrode having a smaller surface area than the activated carbon porous body, and a large amount of hydrogen gas can be generated in a short time. Therefore, compared with the past, the time required for storing hydrogen gas is greatly shortened, and high concentration hydrogen water can be stably supplied for a long time. In addition, calcium carbonate hardly adheres to the surface of the activated carbon porous body, thereby preventing the blockage of micropores and ensuring stable filtration performance.

Next, it is preferable to provide a pressure valve that keeps the inside of the storage container under pressure in the water intake section. As a result, the inside of the reservoir is maintained at the same pressure as the set pressure of the pressure valve. For this reason, the electrolytic gas generated by electrolysis is pressurized inside the container, is forcibly filled into the activated carbon porous body, and stored in a myriad of small spaces. In this state, when water supply is started, water flow is generated by the pressure difference between the water supply pressure of the raw water and the set pressure of the pressure valve inside the water reservoir, and the electrolytic gas stored in the activated carbon porous body is sucked into the water flow, and hydrogen Bubbles of gas are forcibly dissolved in raw water. Therefore, compared with the conventional case where the electrolytic gas was stored and dissolved under atmospheric pressure conditions, a larger amount of electrolytic gas can be stored in the activated carbon porous body, and a higher concentration of hydrogen water can be stably supplied for a long time.

That is, as shown by Equation 1 below, the solubility of the gas is proportional to the gas-liquid contact pressure, so that the internal pressure of the low container is maintained at a pressurized state with a pressure valve, thereby increasing the solubility of hydrogen gas in the raw water. The dissolved hydrogen concentration of the hydrogen water can be improved.

C = kP

Where C is the solubility of the gas

k: Henry's integer

P: pressure

In addition, since the floating speed of the bubbles decreases by pressurizing and reducing the bubbles of hydrogen gas, and the bubbles can stay in the water for a long time, the bubbles of hydrogen gas contained in the water per unit area significantly increase, that is, the following equation By increasing a shown in 2, the dissolution rate of hydrogen gas in raw water can be accelerated.

dCAL / dt = Ka (CA-CAL)

Where CAL: dissolved gas concentration

t: hour

K: liquid side mass transfer coefficient

a: gas-liquid contact area per unit volume

CA: saturated dissolved gas concentration

The kind of pressure valve is not specifically limited, For example, the positive pressure valve which fixed the set pressure to a fixed value, the pressure regulating valve which can adjust a set pressure, the relief valve which can adjust a relief pressure, etc. can be used. In addition, when the water supply pressure uses raw water of about 0.3 MPa * G (G: gauge pressure), the set pressure of a pressure valve is preferably 0.2 MPa * G.

Next, in order to prevent the adhesion of calcium carbonate to the electrolytic electrode, it is preferable to use an AC voltage of extremely low frequency as the electrolytic voltage. In particular, since the electrolytic efficiency is high and the electrolytic reaction is stabilized, the power supply unit is preferably an electrolytic power supply that outputs a square wave AC voltage of 10 ⁻⁴ to 10 ⁻¹ Hz to the electrolytic electrode. When the frequency of the electrolytic voltage exceeds 10 ^-1 Hz, the efficiency of the electrolysis reaction is lowered, and the generation rate of hydrogen gas is reduced. In the region where the frequency is lower than 10 ^-4 Hz, calcium carbonate easily precipitates on the cathode, and although it can be lost at the reverse potential, the electrolysis reaction becomes unstable due to repeated precipitation and disappearance.

In addition, the power supply unit is preferably an electrostatic constant current power source that automatically varies the square wave AC voltage so as to keep the electrolytic current constant. This is because, regardless of the quality of the raw water, the electrolytic current is kept constant, which makes it possible to stabilize the generation of hydrogen gas. Although this square wave AC voltage is not specifically limited, 1-40V is preferable.

The activated carbon porous body is, for example, a conductive molded body formed by binding activated carbon particles with a binder, and has a water purification function for removing organic substances such as chlorine components and trihalomethane in raw water, and a space function for storing electrolytic gas. . As for the water purification function, since the cells of the microorganism are negatively charged in the water where the pH is the neutral region, the activated carbon porous body is positively charged to prevent the collection of the microorganisms without depositing calcium carbonate on the surface of the porous body. It can increase. Specifically, it is preferable to provide a DC power supply that applies a constant voltage of 1 V or more to the activated carbon porous body and a voltage range in which electrolysis does not occur. In addition, hydrogen gas may also be negatively charged, which is effective for adsorption and occlusion of hydrogen. In addition, when the applied voltage is less than 1 V, the collection performance of microorganisms becomes insufficient.

In addition, the structure of a water supply part is not specifically limited, For example, the structure provided with the water supply port connected to the tap of a water pipe or the water supply source of a well through a hose can be employ | adopted. The configuration of the water intake portion is not particularly limited, and for example, a configuration in which a pressure valve is provided at the front end (upstream side) of the discharge port for discharging hydrogen water can be adopted.

In addition, an upstream water reservoir having an anterior water purification chamber upstream from the water supply portion, an anterior water activated carbon member housed in the anterior water purification chamber, an anterior water supply portion for supplying raw water having a predetermined water pressure to the anterior water purification chamber, The pretreatment water purification device which consists of a pretreatment water intake part which takes out pre-purified water from a pretreatment water purification chamber and sends it to a water supply part can also be formed. Although it does not specifically limit as an activated carbon member, A porous body, a powder form, a granule form, etc. can be illustrated. In the translocation water purification chamber, filtration (such as free chlorine, dust, organic matter, lead, etc.) of abdominal water is mainly performed as pre-purification, thereby stabilizing electrolysis in the subsequent electrolytic chamber, and also harmful substances by electrolysis (mainly organic chlorine system). Compound) can be suppressed, and the load of the activated carbon porous body in the purified water chamber can be reduced to extend the life of purifying and adsorption, whereby clean and safe hydrogen water can be formed in large quantities. That is, the activated carbon porous body of the purified water chamber at the back can mainly occlude hydrogen gas.

Hydrogen gas generated at the electrode for electrolysis starts to rise so that the distance between the electrode for electrolysis and the activated carbon porous body does not exceed 100 mm in the left and right directions and does not exceed 100 mm in the vertical direction at the shortest part. Immediately contact the surface of the activated carbon porous body. Install a pressure valve to keep the inside of the reservoir under pressure. The power supply unit is a constant current power supply for electrolysis that outputs a square wave AC voltage of 10 ^-4 to 10 ^-1 Hz to the electrolytic electrode and automatically varies the square wave AC voltage so as to keep the electrolytic current constant.

(Example 1)

The electrolytic hydrogen water generator 1 of Example 1 shown in FIG. 1 is comprised from the water receiving part 2 and the power feeding device 3. The water receptacle unit 2 includes a water storage unit 5 for storing tap water as raw water 4, a water supply unit 6 for supplying raw water 4 to the water storage container 5, and a water storage container 5. A water intake section 8 for taking out the hydrogen water 7 is provided. The low water container 5 is integrally molded into a top and bottom two-chamber structure by a resin material, and the small volume electrolytic chamber 9 on the upstream side is divided into the lower side, and the large volume purified water chamber 10 on the downstream side is divided into the upper side, respectively. Equipped. Both chambers 9 and 10 communicate with each other through the communication port 23.                     

The electrolytic chamber 9 houses a pair (or plural pairs) of electrolytic electrodes 11 for electrolyzing the raw water 4. The electrolytic electrode 11 is formed compactly by a platinum-based metal material, and is disposed in the electrolytic chamber 9 via a predetermined gap. In the purified water chamber 10, the activated carbon porous body 12 for purifying raw water 4 after electrolysis is separated from the electrode 11 for electrolysis, and (although it is natural to see the arrangement of the purified water chamber 10). It extends from the upper end of the electrode 11 for electrolysis upwards, and is accommodated so that the upper level of the activated carbon porous body 12 may be higher than the upper level of the electrode 11 for electrolysis. The activated carbon porous body 12 is formed in a circumferential shape and has a through hole 13 that is longitudinally long in the center portion. In addition, the circumferential outer circumferential surface 24 of the activated carbon porous body 12 is located just above the electrolytic electrode 11, but may be located slightly inside or outside the top just above the electrolytic electrode 11.

The separation distance between the electrolytic electrode 11, the activated carbon porous body 12, and the circumferential outer circumferential surface 24 is substantially 0 in the left and right directions at the shortest portion (or leftward in FIG. 1 (outward direction of the circumferential outer circumferential surface 24). Or 30 mm to 50 mm in the right direction (inward direction of the outer circumferential surface 24 of the circumference). As such, the hydrogen gas generated in the electrolytic electrode 11 starts to float and immediately comes into contact with the circumferential outer circumferential surface 24 of the activated carbon porous body 11. The power feeding device 3 includes an electrolytic power source 14 serving as a power feeding part for continuously supplying a very low frequency square wave AC voltage of, for example, about 10 ⁻³ Hz to the electrolytic electrode 11, and an activated carbon porous body 12. ) Is provided with a DC power supply 15 for applying a constant voltage of 1 V or more and a voltage range in which electrolysis does not occur. The electrolytic power supply 14 is an electrostatic constant current power supply that automatically varies a square wave AC voltage to maintain a constant electrolytic current, and the square wave AC voltage is variable within a range of 1 to 40V.

The water supply part 6 is provided with the water supply valve 16 connected to the water supply source, and the water supply port 17 which opens to the bottom of the electrolytic chamber 9, and supplies the raw water 4 with the water pressure of about 0.3 MPa * G. It is comprised so that it may supply to the electrolytic chamber 9. The water intake section 8 includes a water intake pipe 18 connected to the through hole 13 of the activated carbon porous body 12, a discharge port 19 for discharging hydrogen water 7, and an interior of the water storage container 5. The pressure valve 20 is maintained in a pressurized state, and the pressure valve 20 is provided upstream from the discharge port 19. As the pressure valve 20, a pressure regulating valve capable of adjusting the set pressure in the range of 0.05 to 0.2 MPa · G is used.

In the electrolytic hydrogen water generating apparatus 1 of this embodiment, when a square wave AC voltage is applied to the electrolytic electrode 11, the raw water 4 of the electrolytic chamber 9 falls within a range of, for example, 200 to 500 mA. Electrolysis is carried out at a constant current to be determined, and the square wave AC voltage is automatically changed at around 12 V to generate oxygen gas 21 at the anode and hydrogen gas 22 at the cathode. The polarity of the electrolytic electrode 11 is periodically changed for a relatively long time (for example, 10 minutes), so that the oxygen gas 21 and the hydrogen gas 22 are alternately generated from both electrolytic electrodes 11. . And these electrolytic gas floats in the water purification chamber 10 from the communication port 23, Since the electrolytic electrode 11, the activated carbon porous body 12, and the circumferential outer peripheral surface 24 approach as mentioned above, The very fine hydrogen gas in the early stage of floating can be adsorbed to the activated carbon porous body 12 mostly.

At this time, the inside of the storage container 5 is maintained in a pressurized state of, for example, 0.2 MPa · G by the pressure valve 20. For this reason, electrolytic gas is pressurized by the internal pressure of the container 5, it is forcibly filled inside the activated carbon porous body 12, and is stored in a myriad of small spaces (refer FIG. 5). In this state, when the water supply valve 16 is opened and water is supplied to 0.3 MPa · G raw water 4, the pressure difference between the water supply pressure and the pressure valve set pressure (0.1 MPa.G) inside the water reservoir 5 is caused. Water flow occurs, and the electrolytic gas stored in the activated carbon porous body 12 is sucked into the water flow. Under pressure conditions of 0.2 MPa · G, bubbles of hydrogen gas are forcibly dissolved in the raw water 4 in a state in which the bubbles of hydrogen gas are compressed to a bubble diameter of about 1/3, a surface area of about 1/9, and a volume of about 1/27.

Therefore, according to the electrolytic hydrogen water generator 1 of this embodiment, the following effects are obtained.

(1) Raw water is electrolyzed by an exclusive electrolytic electrode 11 in the electrolytic chamber 9 separated from the purified water chamber 10 without using the activated carbon porous body 12 as the electrolytic electrode. Therefore, there is little fear that calcium carbonate will precipitate on the surface of the porous body 12, and the filtration function of activated carbon can be maintained satisfactorily for a long time. In addition, since a metal electrode having a small surface area can be used for the electrolytic electrode 11, the voltage drop due to the resistance of the raw water 4 is reduced, and the current density can be increased by raising the electrolytic current value to about 200 to 500 mA. As a result, a large amount of hydrogen gas can be generated in a short time by improving the electrolytic efficiency.

(2) The activated carbon porous body 12 extends upward from the upper end of the electrolytic electrode 11, and the electrolytic electrode 11, the activated carbon porous body 12, and the circumferential outer peripheral surface 24 are approaching. Therefore, very fine hydrogen gas in the early stage of floating can be adsorbed to the activated carbon porous body 12 mostly.

(3) Since the inside of the low water container 5 was kept in a pressurized state by the pressure valve 20, the storage amount of the electrolytic gas to the activated carbon porous body 12 and the dissolved hydrogen concentration of the hydrogen water 7 were both about 3 It can increase by double and can supply the high concentration hydrogen water 7 stably over a long time.

(4) Since a very low frequency square wave AC voltage is applied to the electrolytic electrode 11, the adhesion of calcium carbonate to the electrode 11 can be prevented, the electrolytic efficiency can be increased, the electrolytic reaction can be stabilized, and the maintenance work can be omitted. It becomes possible.

(5) Since a constant voltage of 1 V or more is always applied to the activated carbon porous body 12, microorganisms in the raw water 4 charged with negative polarity can be efficiently collected, and leakage of microorganisms can be suppressed, so that hydrogen water 7 Hygiene can be improved. Since a constant voltage is applied, there is no fear that calcium carbonate will precipitate on the surface of the activated carbon porous body 12.

(Example 2)

The electrolytic hydrogen water generator 1 of Example 2 shown in FIG. 2 arrange | positions the electrolytic chamber 9 overlapping with the lower part of the water purification chamber 10, and the electrolytic electrode 11 has the activated carbon porous body ( It is different from Example 1 in that it arrange | positions in parallel with the lower part of 12), and the activated carbon porous body 12 extends from the upper end to the upper side of the electrolytic electrode 11 by this. The separation distance between the electrolytic electrode 11, the activated carbon porous body 12, and the circumferential outer circumferential surface 24 is 5 mm in the left and right direction and substantially 0 in the vertical direction at the shortest part, and thus the electrolysis is performed by approaching both. The hydrogen gas generated at the electrode 11 may start to float and immediately contact the circumferential outer circumferential surface 24 of the activated carbon porous body 11. Therefore, the same effect as Example 1 is acquired also by this Example 2.

It differs from Example 1 only in the point which provided the transposition water purifier 30 which consists of the transposition water intake part 35 sent to the water supply part 6.

The shape of the pre-activated carbon porous body 33 is similar to that of the activated carbon porous body 12, but no voltage is applied, but similarly to the activated carbon porous body 12, even if a constant voltage of a voltage range of 1 V or more and no electrolysis occurs is applied. good. An anterior water supply part 34 is provided in the outer peripheral side of the pre-activated carbon porous body 33, and the said water intake part 35 is provided in the through-hole side of the said activated carbon porous body 33. As shown in FIG.

In the preliminary purification chamber 32, filtration (free chlorine, dust, organic matter, lead, etc.) such as monastic water is mainly performed as preposition purification, thereby stabilizing electrolysis in the subsequent electrolytic chamber 9, and The generation of harmful substances (mainly organochlorine compounds) can be suppressed, and the load of the activated carbon porous body 12 in the purified water chamber 10 can be reduced to extend the life of the purification and adsorption, thereby making the water cleaner and safer. A few can be molded in large quantities. That is, the activated carbon porous body 12 of the following purified water chamber 10 can mainly occlude hydrogen gas.

As described above, according to the electrolytic hydrogen water generator according to the present invention, it is possible to obtain a stable effect of supplying a high concentration of hydrogen water for a long time, and to obtain an excellent effect of almost no adhesion of calcium carbonate to the activated carbon porous body. . In addition, by supplying a square wave AC voltage of 10 ^-4 to 10 ^-1 Hz to the electrode for electrolysis, adhesion of calcium carbonate to the electrode can be prevented, the electrolytic efficiency can be increased, and the electrolytic reaction can be stabilized. In addition, by applying a constant voltage in the voltage range of 1 V or more and no electrolysis to the activated carbon porous body, calcium carbonate is not precipitated on the surface of the porous body, thereby improving the collection performance of microorganisms.
