The electrode member 2 is used in a water tank or the like (underwater), and the power supply member 4 is used on the ground (in the air). The power supply member 4 is managed in a state of being housed in a case or the like, for example, and power is supplied to the electrode member 2 from there using lead wires 5 .
Since the electrode member 2 and the power source member 4 are formed independently of each other, their sizes and weights are divided, and maintenance and management of them can be performed independently, and maintenance of the electrode portion 8 of the electrode member 2 and the like can be easily performed. .

FIG. 2 shows the configuration of the power supply member 4, which includes a control section 11 for managing equipment, a feeder circuit section 12, a DC power supply section 13, and the like. The power supply circuit unit 12 supplies electric power for electrolytic treatment to the electrode plate 6 of the electrode member 2 and the like through the lead wire 5 . The DC power supply unit 13 supplies direct current (DC) power to the power supply circuit unit 12, and includes a power supply unit 13a for electrode driving (24 V to 48 V) for the power supply circuit unit 12, and a control substrate (12 V) for the control unit 11. power supply unit 13b and the like.

The electrode portion 8 of the electrode member 2 includes a first electrode 14 composed of four electrode plates 6 having an L-shaped cross section, a rod-shaped second electrode 16 arranged in the center of the first electrode 14, and a first It has a third electrode 18 made of a mesh that covers the periphery of the electrode 14 of the second electrode. In the first electrode 14, four electrode plates 6 having an L-shaped cross section are arranged around the central portion, and the electrode surface 15 of each electrode plate 6 is made of a mesh.

The electrode member 2 is used while floating on the water surface. For this reason, the electrode part 8 is formed in a circular cylindrical shape as a whole so as to float in the water in a well-balanced manner. The first electrode 14 has four electrode plates 6 arranged evenly around the center portion, and a rod-shaped second electrode 16 is arranged at the center portion of the first electrode 14, The weight of the electrode part 8 is concentrated at the center, and the center of gravity of the electrode part 8 is positioned at the center to improve the stability during floating.

A conductive material is used for each electrode of the electrode section 8, and as the first electrode 14, for example, titanium (Ti) plated with platinum (Pt) is used. A stainless material (SUS316) is used as the second electrode 16 and the third electrode 18 . As described above, any electrode is made of a durable and rust-resistant material such as stainless steel or titanium, or a metal material plated with platinum or the like.

The floating device 10 holds the electrode member 2 thrown under the water surface so that it does not sink in the water, and floats a part of it on the water surface. For this reason, the floater 10 may be a floater-like device that floats on the water surface while holding the electrode member 2 in water.
The float 10 is attached to the periphery of the electrode holding member 9 for use.

FIG. 3 shows a cross section (horizontal) of the electrode member 2 . The electrode plate 6 of the first electrode 14 is composed of a pair of electrode surfaces 15 arranged at right angles. The first electrode 14 uses four electrode plates 6 each having an L-shaped cross section, and each electrode plate 6 has a terminal rod 13 projecting upward from the central portion of the upper portion thereof. The reason why the electrode plate 6 is formed in a mesh shape is to increase the surface area and cause a chemical reaction on both the front and back sides to enhance the effect of electrolysis.

A rod-shaped second electrode 16 is placed in the center, and four electrode plates 6 related to the first electrode 14 are placed around it at regular intervals (90 degree intervals). Further, a cylindrical third electrode 18 is arranged so as to surround the first electrode 14 .

If necessary, a recessed portion having an L-shaped cross section in a specific electrode plate 6 of the first electrode 14 is used to arrange a mineral case containing a mineral material, and a copper rod is arranged vertically. You can Mineral materials consist, for example, of magnesium-zinc alloy plates, which allow mineral substances to be contained in the water, and copper rods are used for sterilization.

The reason why four electrode plates 6 having an L-shaped cross section are used for the first electrode 14 is that when the electrode part 8 is immersed in water with the upper part partially floated, the overall balance is good and stable. This is because the electrode portion 8 can be held in water with a large number of electrodes, and the number of electrodes is increased to improve the ability of electrolytic treatment of water. Further, by forming the electrode plates 6 to have an L-shaped cross section, the area where the electrode surfaces 15 of the electrode plates 6 face each other can be widened, and electrolysis can be performed efficiently.

The electrode surface 15 of the electrode plate 6 has a flat rectangular shape formed in a mesh shape. Each electrode plate 6 is formed by bending the central portion of a flat rectangular mesh material into an L shape. As a result, the electrode plate 6 has a shape in which the flat electrode surface 15 forms a right angle. By making the electrode surface 15 mesh-like, the surface area is increased, the efficiency of the electrolytic treatment is enhanced, and the circulation of water is improved, which contributes to the electrolytic treatment.

The first electrode 14 is arranged at a central portion around which the electrode plates 6 having an L-shaped cross section are arranged, with the corners of the respective electrode plates 6 directed toward the central portion. The electrode plates 6 are arranged at four locations around the central portion at intervals of 90 degrees, and the adjacent electrode surfaces 15 are arranged to face each other in parallel with a constant interval.

In this way, the electrode plates 6 of the first electrode 14 are arranged in the vicinity of the second electrode 16 located in the central portion and facing each other at positions symmetrical with respect to the center of the second electrode 16. be done. As a result, the distance between the rod-shaped second electrode 16 and each electrode plate 6 is balanced, and the electrolysis is performed satisfactorily.
The electrode plate 6 is formed by molding titanium into a net shape by mesh processing, expanded metal processing, or the like. If the electrode plate 6 is plated with platinum, the durability is enhanced and the processing efficiency is improved.

In the first electrode 14, the interval between the adjacent electrode surfaces 15 of each electrode plate 6 is set to 10 mm here, and this range is good for electrolysis in the range of 5 mm to 12 mm.
Each electrode plate 6 of the first electrode 14 is attached with a terminal bar 13 directed upward from the corner, and the upper part of the first electrode 14 is connected to the electrode holding member 9 via the terminal bar 13 . fixed to Also, the terminal rod 13 is electrically connected to the lead wire 5 .

Each electrode plate 6 uses an electrode pressing member 20 so that the electrode surfaces 15 can maintain a constant interval. The electrode pressing member 20 is made of a non-conductive material such as PP (polypropylene).
The electrode pressing member 20 is composed of three types of parts, a pressing member (A), a pressing member (B), and a pressing member (C) having a circular cross section. The pressing members are connected to each other by interposing electrode surfaces 15 interposed therebetween at concave portions on one side and convex portions on the other provided at the center. Then, the electrode holding material (A) and the electrode holding material (B) are arranged on both sides, and the electrode holding material (C) is arranged in the center. A constant distance is maintained between them.
The electrode pressing members 20 are arranged at two positions above and below the first electrode 14 in the vicinity of the upper portion and in the vicinity of the lower portion to stabilize the spacing between the electrode surfaces 15 .

An upper portion of the second electrode 16 is fixed to the electrode holding member 9 via an electrode terminal 34 .
In the second electrode 16, scale such as silica does not adhere to the center electrode material 30 but adheres to the pipe electrode material 32 structurally. .

The third electrode 18 has a cylindrical shape with a bottom and is composed of a cylindrical portion 40 and a bottom portion 42, and is made of stainless steel and is made of a mesh material formed with vertical and horizontal meshes.
The third electrode 18 is, for example, formed by rolling a mesh material made of stainless steel wire into a mesh shape and rolling it into a cylindrical shape. The coarseness of this mesh is #2.5, #5, etc., and #2.5 (mesh), which is coarser, is adopted here.

Both the second electrode 16 and the third electrode 18 are ground electrodes.

In the second electrode 16 , the pipe electrode material 32 can be easily removed by loosening and removing the nut member 48 and pulling out the pipe electrode material 32 from the center electrode material 30 . Then, foreign matter such as scale adhering to the pipe electrode material 32 is removed, and the third electrode 18 is cleaned as necessary. Regarding the pipe electrode material 32 related to the second electrode 16 and the third electrode 18, these electrodes can be easily attached and detached, and maintenance can also be performed easily.
The cylindrical third electrode 18 maintains the balance of the electrode portion 8 when the electrode member 2 is floating, and also contributes to the protection of the electrode portion 8 when the electrode member 2 is handled.

As shown in FIG. 5 , the electrode holding member 9 has a holding body portion 50 that holds the upper portion of the electrode member 2 and a holding cover portion 52 that closes the upper portion of the holding body portion 50 . A non-conductive (insulating) material such as a synthetic resin material is used for the electrode holding member 9 . Here, the holding main body portion 50 and the holding cover portion 52 as the electrode holding member 9 are made of ABS resin material (acrylonitrile-butadiene-styrene copolymer synthetic resin) excellent in impact resistance.
By dividing the electrode holding member 9 into the holding main body portion 50 and the holding cover portion 52, a working area is secured between the two, and the connecting portion between the lead wire 5 and the electrode portion 8 can be well managed and waterproofed. .

The holding body portion 50 is a circular member having a surface portion 54 and a back surface portion 55 .

In addition, holes 62 for attaching fasteners are provided at six locations around the holding cover portion 52 .

FIG. 6 relates to the electrode member 2 and shows a state in which the electrode holding member 9 is attached to the electrode portion 8 . FIG. 1(a) shows a cross section taken along the line AA shown in FIG. 1(b), FIG. 1(b) shows a side view, and FIG. 1(c) shows a plan view.
3 is a cross-sectional view taken along the line BB shown in FIG. 6(a).

7(a) and 7(b) show the float 10. FIG. The floater 10 used here has a floater 66 and a floater case 68 for accommodating or holding the same. As the floating material 66, a synthetic resin material containing air bubbles (closed air bubbles) such as expanded polystyrene is used. Also, as the floater 10, a sealed container filled with air may be used. The floating case 68 is formed in a lattice shape and is made of PP (polypropylene) or the like.

The float 10 here consists of a pair of float pieces 10a, 10b arranged on the left and right. Similarly, the float member 66 is formed of a pair of float member pieces, and the float case 68 is similarly formed of a pair of case pieces. Each of the float pieces 10a and 10b has an arcuate plane and a rectangular cross section, and is mounted around the electrode holding member 9 with the recessed portions facing each other. Also, the float pieces 10a and 10b are arranged with a small gap (S) between them. The hook 57 of the holding body portion 50 is arranged so as to be positioned at the space (S).

Each case piece 68a (68b) of the floating case 68 is formed with an arc-shaped grid and a grid extending toward the center. In addition, the case pieces 68a (68b) are formed with two engaging portions 70 inside each, and holding pieces 72 for holding the floating member 66 are provided inside and outside, respectively.

The float pieces 10a (10b) are attached to the left and right peripheral portions of the electrode holding member 9 so as to face each other in a symmetrical manner. In this case, the locking projections 56 provided at two locations on the holding body portion 50 are engaged with and attached to the locking portions 70 of the float pieces 10a, respectively, and the two locations on the other side of the holding body portion 50 are similarly attached. lock it. In this way, the float pieces 10a (10b) are arranged at symmetrical positions on the periphery of the electrode holding member 9, respectively.

The reason why the floater 10 is divided into the floater pieces 10a and 10b is that the floater 10 can be attached to the electrode holding member 9 relatively easily and the float is well balanced. The floater 10 uses a pair of floater pieces here, but may be configured to use a plurality of pairs of floater pieces. The flotation pieces are arranged symmetrically or evenly spaced to balance the whole. Further, the float 10 may be formed in a ring shape as a whole.
Since the float member 66 of the float device 10 is housed and held in the float case 68, replacement of the float member 66 and the like can be facilitated, and maintenance can be easily performed.

The hook 57 of the electrode holding member 9 is used when the electrode member 2 cannot be put into the water tank or the like because the float 10 is in the way, such as when the opening for the water tank or the like is narrow. In this case, the float 10 is removed from the electrode holding member 9 of the electrode member 2, and the electrode member (2) consisting of only the electrode holding member 9 and the electrode portion 8 is obtained. The float 10 can be attached and detached by removing the locking portion 70 of each float piece 10 a from the locking projection 56 of the electrode holding member 9 .

Then, instead of the floating device 10, the electrode member (2) is suspended by hooking it to a hanging tool or the like by using the hook 57, or by hooking the hook 57 to the edge of the water tank or the like, and the electrode holding member 9 is attached. Leaving a part, the electrode part 8 is immersed in water. That is, the electrode member (2) is held in a floating state by locking the hooks 57 or the like, as in the case of using the float 10. FIG. As a result, the electrode member (2) can be put into a water tank or the like, and even if the inlet of the water tank or the like is narrow, the hydrogen water generator can be used.
In this case, the amount of water in the water tank or the like may be adjusted appropriately.

FIG. 8 is an electric circuit diagram of the power supply circuit portion 12 in the power supply member 4, and FIG. 9 is a schematic diagram of the electrode portion 8. As shown in FIG.
A variable resistor 74 is provided between the electrode plate 6 of the electrode unit 8 and the DC power supply unit 13 to convert the DC current from the DC power supply into a high-frequency AC current to generate the electrode plates 6(A) and 6(B). , 6(C) and 6(D) are supplied with an AC voltage, and the remaining two are ground electrodes.

Two high frequency alternating currents and one high frequency direct current are connected to the high frequency switches 75A and 75B from a data selector 78 . Then, the output of the data selector 78 is switched by the counter frequency divider 73, the ground electrode is exchanged with the AC electrode, and the ground electrode is switched to the AC electrode, thereby removing the scale adhering to the electrode.
Therefore, cleaning (maintenance) of scale such as silica adhering to the first electrode 14 can be performed by switching between the ground electrode and the AC electrode.

The high frequency switches 76A, 76B and the high frequency switches 77A, 77B are connected to a high frequency switching circuit 80 comprising an FF circuit for giving a high frequency switching command via a data selector 78 via resistors 79A, 79B. The high frequency switching circuit 80 is connected to a high frequency oscillation circuit 81 comprising a voltage controlled oscillator (VCO) whose oscillation frequency changes in response to a control signal. A control circuit 82 containing a random voltage generator is connected to the high-frequency oscillator circuit 81 .

High-frequency oscillator circuit 81 is a variable-frequency oscillator circuit whose oscillation frequency is controlled by the voltage value of a control signal applied to a voltage controlled oscillator (VCO). At this time, FM modulation is applied with a fluctuation range of ±3 to 5 kHz centering on an AC oscillation frequency of about 5 to 100 kHz. Here, the fluctuation range of the frequency is, for example, 3 to 5 KHz above and below the center frequency (30 KHz).

The control circuit 82 supplies a control voltage to the high frequency oscillation circuit 81 for controlling its oscillation frequency. This control circuit 82 incorporates a random signal generator and outputs a control signal whose voltage value changes according to the random signal generated by the generator. The sist register (SFR) 83 has a 16-stage structure, and its accumulated information can be read in parallel from terminals Q0 to Q15. The shift operation of this shift register 83 is controlled by a shift pulse supplied from a pulse generator (PG) 84 to terminal CK of shift register 83 . The pulse generator 84 performs an inversion operation, and each time the pulse generator 84 inverts, the frequency fluctuates sharply.

The gate GT is a gate that performs an exclusive OR operation and acts as a match detection circuit. One of the input terminals of this gate GT receives the signal output from the even-numbered stage of the shift register SFR, for example, the terminal Q6 of the sixth stage, and the other terminal receives the signal output from the terminal Q6 of the ninth stage, for example, the odd-numbered stage. Each output signal is input. The result of match detection by this gate GT is input from the terminal D of the shift register SFR to the lowest 0th stage. Random number information is stored in the shift register 83 by sequentially shifting this information upward.

The random number information stored in shift register 83 is tapped by resistors from approximately half of the appropriately selected stages. Here, signals are extracted from the first, third, eighth, tenth, and 12th to 15th stages. A resistor r connects the terminals Q1, Q3, Q8, Q10, Q12-Q15 of each of these stages to a common node A. This connection point A is connected to a voltage controlled oscillator (VCO) that constitutes a high frequency oscillator circuit 81 . A voltage controlled oscillator (VCO) is also connected to a pulse generator (PG) 84 .

Accordingly, when the pattern of random number information stored in each stage changes, the combined value of the resistors r connected to the high level and the low level changes, so that the voltage at the connection point A fluctuates accordingly. to create a random signal. The voltage at the connection point A gradually fluctuates due to the resistor R1 and the capacitor C1, but the signal from the pulse generator 84 causes a sudden up-and-down fluctuation.

The pulse generator 84 is a pulse generator that emits continuous pulses with a center frequency of, for example, 5 Hz, and is configured so that the period of repetitive pulses changes according to the voltage value of the signal that is input to the voltage controlled oscillator (VCO). It is The fluctuation range of this frequency is about several kHz above and below the center frequency.

A terminal of the pulse generator 84 is supplied with the voltage at the connection point A through a resistor R5. Therefore, the pulse generator 84 varies its pulse repetition period according to the random signal from the shift register SFR. The shift register SFR uses the output of the pulse generator 84 as a shift pulse. Therefore, the control signal output to the voltage-controlled oscillator (VCO) changes completely at random in both its voltage value and fluctuation period. are producing.

In the control circuit 82, the control signal is generated using patterns of random number information stored in about half of the stages of the shift register 83. FIG. Furthermore, as described above, as the input information of the shift register 83, the match detection result of the information selected one stage each from the even number and the odd number is used. Areas of intense fluctuation appear frequently, and shock waves are generated at this time.

Here, the electrical connection between the power supply circuit portion 12 of the power supply member 4 and the electrode portion 8 will be described.
FIG. 9A shows the arrangement of the electrode plates 6 of the first electrode 14, the second electrode 16, and the third electrode 18 in the electrode section 8. FIG.
Further, as shown in FIG. 4(b), as a connection form between the power supply circuit portion 12 and the electrode portion 8, one of the four electrode plates 6 of the first electrode 14 of the electrode portion 8 is oriented diagonally. A matching pair of electrode plates 6 is used as a main electrode (M) through which alternating current flows, and the other pair of electrode plates 6 is used as a ground electrode (G).

For example, of the four electrode plates 6 of the first electrode 14, two electrodes facing diagonally (electrode plates 6 (A) and (C)) serve as main electrodes (M), and the other two electrodes (electrodes The plates 6 (B), (D)) serve as the ground electrode (G). These electrodes are switched between the main electrode (M) and the ground electrode (G) every 3 to 15 minutes, for example, in order to clean the electrode surface 15 of the electrode plate 6 associated with the first electrode 14. (left and right arrows).

Also, since the second electrode 16 is in the state of a ground electrode, it exhibits the same electrical function as the ground electrode (G) related to the first electrode 14 . In this case, when the first electrode 14 becomes the main electrode (M), a current also flows to the second electrode 16 from this.
The second electrode 16 is a ground electrode (G) provided to enhance the electrolysis effect of the first electrode 14, and it has been confirmed that this enhances the electrolysis ability (about several percent). ing.

Next, operation of the hydrogen water generator will be described.
The power source member 4 shown in FIG. 2 includes a power supply circuit portion 12, a DC power source portion 13, etc., a power switch 85, a timer portion 86, relay terminal blocks 87 and 88, a display portion 89, an operation display lamp 90, an ammeter 92, It has a current regulator 94, an earth leakage circuit breaker 96, a fan 98, and the like.
The power supply member 4 is powered by an alternating current (AC100V).

Electric power is supplied to the electrode member 2 from the power supply circuit portion 12 of the power source member 4 via the electrical relay terminal block 87 and the lead wire 5 . The relay terminal block 87 is electrically connected to each electrode plate 6 of the first electrode 14 , the second electrode 16 and the third electrode 18 .
In the hydrogen water generator, the electrode member 2 is placed in a water tank or the like, and the electrode part 8 is partially floated on the surface of the water and used underwater, and the power supply member 4 is placed on the ground (in the air) and used.

For this reason, the electrode member 2 is first put into water when operating. At this time, the electrode part 8 of the electrode member 2 is immersed in the water, and the floater 10 causes the electrode holding member 9 and part (or half) of the floater 10 to float on the water surface. In this manner, the electrode member 2 is partially floating on the water surface. In this state, the operation of the power supply member 4 and the electrode member 2 relating to the hydrogen water generator is started and continued.

Now, when the power switch 85 of the power source member 4 placed on the ground is turned on, electric power for electrolysis is supplied from the power supply circuit section 12 to the electrode plate 6 of the electrode member 2 and the like.
In the power supply circuit section 12, a control signal corresponding to the random signal is sent from the control circuit 82 to the high-frequency oscillation circuit 81, and the oscillation frequency is controlled and changed randomly. A randomly varying high-frequency signal is applied to the high-frequency switching circuit 80 from the high-frequency transmission circuit.

When a random high-frequency signal is given to the high-frequency switching circuit 80, a high-frequency switching command is issued from here. is turned ON and OFF with . As a result, a randomly varying high-frequency alternating current is formed, which is applied to one pair of the four electrode plates 6 placed in the water, and the other pair of electrode plates 6 are grounded.

Here, the oscillation frequency sent out from the high-frequency oscillation circuit 81 has a voltage value and a duration of the voltage value that vary completely randomly, and frequently has an extremely violently fluctuating portion in which the voltage value rises sharply and then drops sharply. contains.
As a result, the hydrogen and oxygen bubbles generated by the electrolysis treatment by the power supply from the power supply circuit section 12 become smaller nano-sized bubbles (nanobubbles) due to the high frequency and the shock wave, and are dissolved in the water. The generation of this nanobubble hydrogen water has been confirmed by an inspection by an inspection agency.

In the power supply circuit unit 12 in the power source member 4, ON/OFF control of the power switch 85, lighting and extinguishing of lamps and the like, management of timers, and the like are performed. Here, a 24-hour timer provided in the timer section 86 can freely designate ON/OFF of the electrolysis treatment time within 24 hours. Further, the earth leakage circuit breaker 96 controls to automatically stop the energization when the electrode member 2 or the like is lifted out of the water during the energization, or when the electrodes contact each other (short circuit).

When water is electrolyzed using a hydrogen water generator, scale (impurities such as silica) adheres particularly to the ground electrode and the like related to the first electrode 14 . Due to the adhesion of scale, the current value related to each electrode is lowered, and the treatment efficiency is deteriorated.
Therefore, the electrode plate 6 associated with the first electrode 14 can be cleaned of scales on the electrode surface 15 of the electrode plate 6 by switching between the ground electrode and the AC electrode (for example, every 12 minutes).

On the other hand, for the second electrode 16 as well, since scale adheres to the pipe electrode material 32, electrode maintenance (maintenance) such as removal of scale is performed. In this case, scale does not adhere to the center electrode material 30 associated with the second electrode 16, so maintenance is not substantially required.
As for the third electrode 18, some scale may adhere to it, and in this case also, similar maintenance is performed. Maintenance is performed regularly or as needed depending on the degree of scale (impurity) adherence, although it depends on how long the device has been used.

For maintenance of the second electrode 16 and the third electrode 18, the nut member 48 screwed to the bottom of the second electrode 16 (and the third electrode 18) is removed. By this removal, the pipe electrode material 32 associated with the third electrode 18 and the second electrode 16 can be removed. The pipe electrode material 32 can be easily removed by pulling it out from the center electrode material 30 .

Then, the pipe electrode material 32 is cleaned by removing the scale adhering to it using a brush, a detergent material, or the like. At the same time, the cylindrical portion, bottom portion, etc. of the third electrode 18 are also removed, if any scale or the like adheres thereto.
Since the electrode part 8 of the electrode member 2 is exposed, maintenance of the first electrode 14, the second electrode 16, and the third electrode 18 is easy, contributing to durability and workability. .

It has been confirmed that the power supply circuit unit 12 used in the power supply member 4 of this hydrogen water generator generates high-concentration nano-bubble hydrogen water by fine bubbles through electrolysis by high-frequency alternating current supplied from it.
Also, here, electric power (high-frequency alternating current, etc.) was supplied from the power supply member 4, the electrode member 2 was put into the water tank, and the hydrogen water generator was operated, and the test was conducted, and the results are shown.

FIG. 10 is a table showing the test results, conductivity from raw water (μs / cm), ORP (mV), hydrogen concentration (ppb), free chlorine (mg / L), total chlorine (mg / L), etc. was measured. The amount of water in the water tank is 500 liters, and the water temperature is 26.4°C. Further, the electrode driving voltage was set to 24 V, and the main electrode (M) and the ground electrode (G) relating to the first electrode 14 were switched every 12 minutes.
Measurements were then taken after 1 hour, 2 hours, and up to 8 hours after the operating time of the hydrogen water generator from the state of the raw water.

According to the above table, the ORP value became negative after 1 hour, and -343 mv after 8 hours, clearing the target value (-300 mv). The ORP value indicates the oxidizing power/reducing power, and the larger the negative value, the stronger the reducing power. As hydrogen water, at an ORP value of −300 mv, it is shown that high-concentration hydrogen water is generated. In addition, a decrease in the amount of chlorine was observed, albeit to some extent.
In addition, similar tests were carried out on other third electrodes 18 having mesh coarseness of #5 and #2.5. As a result, it was confirmed that #2.5, which has a coarser mesh, decreased the ORP value more quickly, and this is considered to be due to the improvement of water flow.

Most of the hydrogen dissolved in water (bubbles, etc.) is usually released into the air over time, and usually remains dissolved for only a few days. However, nanobubbled hydrogen is known to be dissolved in water for a long time. Most of the hydrogen water generated by electrolysis by the hydrogen water generator is dissolved in water as nanobubble hydrogen water, and therefore, the effect of hydrogen water that can be stored for a long time is maintained. Therefore, it can be stored and managed with confidence, and it can be expected to have an excellent practical effect as hydrogen water.

In addition, the hydrogen water generated by the hydrogen water generator has been confirmed to have a wide range of effects such as human health maintenance and beauty care, and also contributes to livestock diseases, odor reduction, and plant growth and growth promotion. It is also expected that
In the electrolysis of water, oxygen gas is generated from the anode and a part of oxygen water is produced. It is possible.

As described above, according to the hydrogen water generator according to this embodiment, since the electrode member and the power source member are separated, handling and maintenance are facilitated. , maintenance and management can be facilitated by using a nearby container for storing water, the capacity of the container and the amount of water can be adjusted, and versatility is excellent, and electrode management is also easy. In addition, hydrogen water can be stored for a long period of time, which greatly contributes to practical use.

In addition, according to this hydrogen water generator, the maintenance of each electrode related to the electrode member is easy, especially the pipe electrode material that requires maintenance can be easily attached and detached, and impurities such as scale on the electrode can be removed. Cleaning such as removal can be easily performed, improving maintainability, thereby maintaining good electrical conduction characteristics of the electrodes, contributing to electrolysis, and leading to the production of large amounts of hydrogen water.
