Description

The present invention relates to a hydrogen water generator that produces high-concentration nanobubble hydrogen water that can be stored for a long period of time by electrolysis.

Regarding the electrolysis of water, in Patent Document 1, the first, second, and third electrodes are arranged in water, an electric current is applied between the first and second electrodes, and the third electrode is grounded. Then, a direct current is generated in the water between the first and second electrodes and the third electrode, and a direct current is passed through the water between the first and second electrodes and the third electrode. A method for modifying water by electrolyzing water to lower the oxidation-reduction potential of the water is disclosed.
Here, a high frequency of 30 kHz to 50 kHz is used as the alternating current. Further, the direct current can electrolyze water to lower the redox potential of water and lower the COD value of water.

In Patent Document 2, a pair of AC electrodes made of a metal that lowers the oxidation-reduction potential and a first grounding electrode are arranged in a liquid, and the pair of AC electrodes and the first grounding electrode are provided. A mesh-like second grounding electrode having a substantially box shape is arranged around the surface, AC is applied between the pair of AC electrodes, and the first grounding electrode is periodically grounded. A method for AC electrolysis of a liquid, which controls the application of AC from the potential of the above and lowers the oxidation-reduction potential of the liquid, is disclosed.

Here, too, a frequency fluctuation of about 3 to 5 kHz is given above and below the center frequency (about 30 kHz) as an alternating current, and a rapid frequency fluctuation is caused. Further, by performing the flip-flop inversion operation, the frequency fluctuates sharply every time the flip-flop is inverted. Then, a pair of plate-shaped AC electrodes, a plate-shaped ground electrode, and the like are shown, and by applying the AC or the like, the redox potential of the liquid is lowered and the amount of hydrogen generated is increased.

Further, in Patent Document 3, in addition to electrolysis by alternating current, a portion where the frequency rises or falls sharply during frequency fluctuation is brought about, thereby creating a shock wave that causes electric field interference, and bubbles such as hydrogen are generated. It has been shown that nanobubbles were reduced to nanobubbles by high frequency and shock waves, and minute bubbles of 0.5 μm or less were generated by actual measurement. In addition, the number of bubbles 27,000 / ml when 2 liters of water is treated at 30 KHz for 20 minutes becomes as large as 54,000 / ml with shock wave modulation, and the size of the bubbles is 0.5 to 0. It is stated that it was 1 μm.

Therefore, the inventor of the present application has prototyped a hydrogen water generator for further practical use. In this device, two types of electrodes shown in FIG. 9 are arranged in a container of an electrolytic cell.
These electrodes are attached to a lid member that covers the upper part of the container, and consist of a rod-shaped (circular cross-section) ground electrode 122 and flat plate-shaped main electrodes 124 arranged on both sides of the ground electrode 122. The main electrode 124 has a pair of main electrode plates 124a and 124b. These electrodes are arranged parallel to each other.

The distance (K) between the ground electrodes 122 and the main electrode plates 124a and 124b was set to (K =) 14.5 mm, respectively. Further, the diameter (M) of the ground electrode 122 was set to 8.5 mm, and the width (N) of the main electrode plates 124a and 124b was set to 40 mm, respectively.
Here, as the distance (K) between the electrodes, the distance between the electrodes related to the conventional electrolysis was referred to. Further, the rod-shaped ground electrode 122 is adopted from the viewpoint of maintenance and the like.
Further, electricity was supplied to each electrode from a power supply circuit (disclosed in Patent Document 2), alternating current was applied to the pair of main main electrode plates 124a and 124b, and the ground electrode 122 was grounded. The water in the electrolytic cell was electrolyzed using this hydrogen water generator, and the particle size and the number of particles of the hydrogen bubble were measured as the amount of hydrogen generated by outsourcing to a private institution.

FIG. 10 is a graph showing the measurement results. In this graph, the horizontal axis shows the particle size (Size (nm)) of hydrogen bubbles, and the vertical axis shows the number of particles (unit: E6) as the concentration (Concentration (Particles / ml)). The time required for electrolysis here was 3 hours, and minerals for increasing the conductivity of water were added to the raw water (tap water) before electrolysis used. The measurement was performed immediately after electrolysis.
From this graph, it can be seen that the particles are distributed around the particle size of the hydrogen bubble of 200 nm. The number of particles (bubbles) generated by the hydrogen water generator was 559 million particles / mL in 1 mL. From this, it was confirmed that hydrogen bubbles of nano-sized particles were generated as hydrogen water.

The electrolytic cell 6 is used in a state of being placed on the base portion 16 of the main body portion 4. The electrolytic cell 6 has a cylindrical shape, an inner diameter of about 220 mm, and a height of 170 mm.

Then, the lid member 8 is arranged so as to cover the upper part of the electrolytic cell 6. The lid member 8 has a disk shape as a whole, and is connected to an arm portion 18 extending upward from a part of the main body portion 4 via a connecting receiving portion 34 formed in a part of the peripheral portion. ..

There is. Further, mounting portions for various electrodes are formed on the back surface portion 36 of the lid member 8.

As described above, the electrolytic cell 6 is independent of the main body 4, and can be removed from the main body 4 as needed when the lid member 8 is opened, and maintenance such as water injection or cleaning can be performed. Here, the maximum amount of water that can be filled in the electrolytic cell 6 is 5 liters. This amount of water is determined in consideration of the capacity, weight, installation location, etc. of the hydrogen water generator, which can be sufficiently consumed in the home or in the facility. In addition, it is possible to cover an amount of water of about 3 to 8 liters. If the amount of water is increased, it can be dealt with by increasing the time required for electrolysis.

Further, the lid member 8 rotates about the rotation shaft 32, and when the lid member 8 is opened, the lid member 8 is opened and moved by the stopper 40 in a state of an opening angle of 90 degrees or more (for example, 120 degrees) from the closed state. Stops. At the same time, the stopped state of the lid member 8 is maintained at the opening angle by the function of holding the stopped state by the lock function or the like. In the stopped state of the lid member 8, maintenance work such as attachment / detachment and attachment of each electrode related to the electrode member 10 is possible.

The power supply unit 14 of the power supply in the main body 4 generates and supplies electricity for electrolysis. The electricity from the power feeding unit 14 passes through the arm unit 18 by electrical wiring, and is sent from the arm unit 18 to the connection terminal 42 of the lid member 8 via the connecting unit 20.
The electric wiring supplied for electrolysis includes an AC electric wiring sent to the second electrode 52 and an electric wiring such as a ground (ground electrode) for the first electrode 50. The third electrode 54 is electrically grounded via the first electrode 50. From the power feeding unit 14, alternating current electrical wiring is provided to each of the pair of electrode plates 52a and 52b forming the second electrode 52.

FIG. 2 is an exploded perspective view of the lid member 8 and the electrode member 10 and the like attached to the back surface portion 36 of the lid member 8. An electrode connection terminal 42 is provided on the back surface portion 36 of the lid member 8.
The electrode member 10 includes a rod-shaped first electrode 50, a second electrode 52 composed of a pair of electrode plates 52a and 52b, and a tubular third electrode 54.
The first electrode 50 has a central electrode material 60 at the center thereof, and a pipe electrode material 56 having a cylindrical shape or the like that covers the periphery of the central electrode material 60 and is detachably fitted to the central electrode material 60. The pipe electrode material 56 has conductivity, and is in electrical contact with the center electrode material 60 and is electrically conductive.

As the material of each of the first, second, and third electrodes, a conductive material is used, and for example, titanium, stainless steel, magnesium, aluminum, and the like are used. It is also effective to plate the surface of each material with platinum or the like. Here, as the material of the second electrode 52, a titanium material plated with platinum is used. Platinum plating maintains good electrical properties as an electrode. Further, the first electrode 50 and the third electrode 54 are both made of stainless steel to improve the durability of the electrodes.

The first electrode 50 has a rod shape, and the pipe electrode material 56 is fitted to the center electrode material 60 having a circular cross section so as to cover the center electrode material 60. The pipe electrode material 56 is made of a cylindrical pipe material. An electrode terminal 62 is formed at the upper end of the center electrode material 60, and a screw portion 64 having a thread groove formed at the lower end of the center electrode material 60 projects. The length of the pipe electrode material 56 is the same as (similar to) the length of the center electrode material 60, and the center electrode material 60 has a shape completely covered by the pipe electrode material 56. Therefore, substantially, the electrolysis of the first electrode 50 is performed by the pipe electrode material 56.

In the first electrode 50, the scale such as silica does not adhere to the center electrode material 60, and maintenance may be performed on the pipe electrode material 56 to which the scale adheres.
Here, the center electrode material 60 of the first electrode 50 is a columnar shape having a diameter of 5.7 mm. The outer diameter of the pipe electrode material 56 is 8.0 mm, and the inner diameter is a diameter that is in close contact with the center electrode material 60 (a diameter of about 5.8 mm). Therefore, the apparent diameter of the first electrode 50 is 8.0 mm.

The second electrode 52 is composed of a pair of plate-shaped electrode plates 52a and 52b. These electrode plates 52a and 52b have a rectangular (longitudinal) plate shape in which a mesh is formed. Further, an electrode terminal 66 projecting upward is formed in the central portion of the upper portion of each of the electrode plates 52a and 52b. The electrode plates 52a and 52b are formed in a mesh shape in order to increase the surface area and cause a chemical reaction on both the front and back surfaces to enhance the effect of electrolysis.

The arrangement of the electrode plates 52a and 52b of the second electrode 52 is arranged in the vicinity of the first electrode 50 and at a position symmetrical with respect to the center of the first electrode 50, respectively. As a result, the distance between the rod-shaped first electrode 50 and the electrode plates 52a and 52b is balanced, and electrolysis is stably performed.

The third electrode 54 has a bottomed tubular shape composed of a tubular portion 70 and a bottom surface portion 72, and is made of stainless steel and is made of a mesh material having vertical and horizontal meshes formed therein. The tubular portion 70 has a cylindrical shape, and an upper cover material 71 and a lower cover material 73 are attached to each periphery of the upper and lower portions of the tubular portion 70, respectively. An annular wire 75 for reinforcement is attached to the middle portion of the tubular portion 70. Further, the bottom surface portion 72 has a flat shape in which a mesh similar to that of the tubular portion 70 is formed, and a ring material 76 provided with an insertion hole portion 74 is attached to the central portion thereof.

The electrode terminal 62 of the center electrode material 60 of the first electrode 50 is connected to the connection terminal 42 of the back surface portion 36 of the lid member 8 by welding, soldering, or the like, and each electrode plate of the second electrode 52. The electrode terminals 66 of 52a and 52b are similarly connected. Therefore, each of the electrode terminals of the first electrode 50 and the second electrode 52 is firmly fixed to the connection terminal 42 of the lid member 8.
In the electrolysis of water by the electrode member 10, the pair of electrode plates 52a and 52b of the second electrode 52 as AC electrodes and the first electrode 50 and the third electrode 54 as ground electrodes are used in the electrolytic tank 6, respectively. It is submerged in water and energized between each electrode for electrolysis treatment.

Further, here, as the magnesium alloy material, the magnesium and zinc alloy plate 80 is housed in the alloy plate case 82, and this is used together with the electrode member 10. The alloy plate 80 contains abundant minerals in the water of the electrolytic cell 6.
The electrode holder 84 supports and holds the lower side of each electrode. The electrode holder 84 has a holding portion for the second electrode 52, a supporting portion for the pipe electrode material 56, and a case holding portion for the alloy plate 80. Further, a through hole portion 86 that penetrates vertically is formed in the central portion of the electrode holder 84.

The first electrode 50 is located at the center of each electrode, and other electrodes are arranged with reference to the first electrode 50. As a form when the hydrogen water generator 2 is used, the first electrode 50 is attached to the lid member 8 so as to face directly below (hanging).
Then, with the first electrode 50 sandwiched between them, the electrode plates 52a and 52b related to the second electrode 52 are attached so as to face directly below as described above. The electrodes 52a and 52b are arranged so that their surfaces are parallel to each other and are symmetrical with respect to the first electrode 50.

FIG. 3 shows a cross section of the electrode member 10 and the like. The first electrode 50 is a ground electrode. As the second electrode 52, an AC voltage or the like is applied to the pair of electrode plates 52a and 52b, respectively. The third electrode 54 is a ground electrode similar to the first electrode 50.
In the first electrode 50, there is almost no gap between the center electrode material 60 and the pipe electrode material 56 so that both can be inserted into the first electrode 50. The pipe electrode material 56 and the center electrode material 60 are electrically conductive by contact, and the pipe electrode material 56 is electrically integrated with the center electrode material 60.

In the first electrode 50, the action of electrolysis is performed by the pipe electrode material 56, impurities of scale (silica or the like) also adhere to the pipe electrode material 56, and the scale or the like does not adhere to the center electrode material 60.
The center electrode material 60 of the first electrode 50 and the upper portion of the second electrode 52 are fixed to the lid member 8, and both the pipe electrode material 56 and the third electrode 54 are detachably held.

The third electrode 54 is formed in a tubular shape having a size that covers the periphery of the first electrode 50, the second electrode 52, and the like, and the length of the upper and lower electrodes (center line of the cylinder) is the first electrode 50. Is about the same length as.
The reason why the third electrode 54 is tubular and formed in a mesh shape as a whole is also to increase the surface area of the electrode and cause a chemical reaction on both the front and back surfaces of the tubular shape to enhance the effect of electrolysis. Here, the tubular portion of the third electrode 54 has a circular cross section, a diameter of 70 mm, and a height of 137 mm.

FIG. 4 shows a cross section (horizontal) of the electrode member 10. Here, based on FIG. 4, the arrangement form of each of the electrodes and the distance (L) between the first electrode 50 and the electrode plates 52a and 52b of the second electrode 52 will be described. Here, the distance (L) between the electrodes indicates the shortest distance between the first electrode 50 and the second electrode 52.
Electrolysis is mainly performed between the first electrode 50 and the second electrode 52 by direct current, and hydrogen is also mainly generated between these electrodes by electrolysis. Then, regarding the relationship between the distance (L) between the electrodes and the effect of electrolysis, the amount of hydrogen generated in the electrolytic water was investigated by changing the distance (L). Since the amount of hydrogen generated by electrolysis is substantially proportional to the ORP value (oxidation-reduction potential) of the electrolyzed water, the amount of hydrogen was predicted here by measuring the ORP value.

In the measurement, the reaction of electrolysis was investigated by varying the distance (L). At this time, if the distance (L) is gradually narrowed, the amount of hydrogen increases until the distance (L) is around 4.5 mm, and even if the distance is further narrowed, there is no noticeable increase in the electrolysis reaction. rice field.
On the other hand, it has been confirmed in an in-house test that if the distance (L) between the electrodes is too narrow, the amount of scale (impurities such as silica adhering to the first electrode 50 and the like) increases. Further, it has been confirmed that tap water and the like contain a small amount of chlorine, and that the amount of chlorine generated by electrolysis increases as the distance (L) between the electrodes becomes narrower.

From these, the distance (L) between the electrodes was set to about 4.5 mm, which was the optimum distance for practical use because the amount of hydrogen generated was large and the amount of scale and chlorine could be reduced. Further, since the generation and effect of the same amount of hydrogen are expected even in a range close to this distance (L = 4.5 mm), it is preferable that the distance (L) is in the range of 3.0 mm to 6.0 mm. Conceivable.

The first electrode 50 has a rod shape with a circular cross section, and its diameter (F) is 8 mm (about).
This is because it has been confirmed that the reaction of electrolysis is enhanced when the shortest distance between the electrodes is concentrated. Therefore, the first electrode 50 is shaped like a rod so that the portion at the shortest distance from the second electrode 52 is concentrated. In this case, if the distance (L) between the electrodes is narrowed, the part having the shortest distance is more concentrated and the reaction of electrolysis is enhanced.
Further, when the first electrode 50 is formed in a rod shape, the scale can be easily removed, whereby the efficiency of electrolysis can be maintained well.

Further, as described above, when the distance between the first electrode 50 and the second electrode 52 is narrowed, impurities such as scales adhere to the first electrode 50 relatively much during electrolysis. Therefore, here, as a measure for quickly and easily removing the scale adhering to the first electrode 50, the first electrode 50 is divided into a center electrode material 60 and a pipe electrode material 56.
Then, the pipe electrode material 56 is made removable from the center electrode material 60, and the pipe electrode material 56 is removed so that maintenance such as removal of the scale adhering to the pipe electrode material 56 can be easily performed. As a result, electrolysis can be performed efficiently, which also contributes to the generation of a large amount of high-concentration nanobubble hydrogen water.

Since the diameter (F) of the first electrode 50 does not change the reaction and efficiency of electrolysis even if this diameter is changed, rather, the maintenance and maintenance of the electrodes are taken into consideration. It was set to 8 mm for ease of use. Regarding this diameter (F), it is considered that a range of 6 mm to 12 mm is practically appropriate from the viewpoint of maintenance and management.
As the first electrode 50, a form in which the pipe electrode material 56 is fitted to the center electrode material 60 is adopted here, but when only the reaction of electrolysis is considered, the center electrode material 60 (for example, the diameter) is adopted. It is also possible to adopt a form in which electrolysis is performed using only 8 mm), and in this case, there is no change in the reaction of electrolysis and its effect.

Each of the electrode plates 52a and 52b of the second electrode 52 has a net body and a plate shape, but this is because the efficiency of electrolysis is taken into consideration, and the shortest distance from the first electrode 50 is good. It is also for forming. The width (W) of each of the electrode plates 52a and 52b of the second electrode 52 was 48 mm, and the height was 126 mm. This width (W) is set to a practical dimension because no effect can be expected even if it is made too wide in relation to the reaction distance of electrolysis with the first electrode 50. This width is preferably in the range of 30 mm to 60 mm in view of the electrolysis capacity, the dimensions of the container, and the like.

The third electrode 54 has a tubular shape, but here, the diameter (φ) of the tubular portion 70 is 70 mm. This diameter is preferably formed to be 20 mm (about) smaller than the width of the second electrode 52 in consideration of the efficiency of electrolysis and the width of the second electrode 52.
Further, the third electrode 54 is a ground electrode, in order to prevent the generation of chlorine. According to an in-house test, it has been confirmed that the amount of free chlorine in the water after electrolysis is significantly reduced by grounding the third electrode 54.
If the third electrode 54 is made larger than necessary, the effect of electrolysis will be diminished, but due to the configuration, it is necessary to house the second electrode 52, the first electrode 50, etc. inside. It was set to 70 mm. The diameter (φ) of the tubular portion is also practically in the range of 60 mm to 80 mm.

FIG. 5A shows a power supply circuit related to the power feeding unit 14. The power supply circuit has the same basic configuration as the electric circuit described in Patent Document 2.
Between the electrode plates 52a and 52b of the second electrode 52 and the DC power supply 94, the DC current from the DC power supply 94 is converted into high-frequency alternating current and applied to the electrode plates 52a and 52b via a variable resistor 95. High frequency switches 96a and 96b are connected. These high frequency switches 96a and 96b are composed of transistors 97a and 98a and 97b and 98b, respectively.

A circuit is connected to the second electrodes 52a and 52b via a capacitor 99, and alternating current is applied between the electrodes of the pair of electrode plates 52a and 52b.
The DC power supply 94 can be selected and adjusted in the range of 10 to 50 V according to the amount of treated water and the like and the application. Here, the power supply voltage is used in the range of 18 to 24V. In the in-house test, when the reaction of electrolysis was measured in the range of 18 to 24 V for the power supply voltage, there was no significant change in this range.

A high frequency switching command circuit 101 including a flip-flop circuit that gives a high frequency switching command to the high frequency switches 96a and 96b via resistors 100a and 100b is connected to the high frequency switches 96a and 96b, respectively. A high frequency oscillation circuit 102 composed of a voltage controlled oscillator (VCO) whose oscillation frequency changes in response to a control signal is connected to the high frequency switching command circuit 101. A control circuit 103 having a built-in random voltage generator is connected to the high-frequency oscillation circuit 102.

The high frequency oscillation circuit 102 is a variable frequency type oscillation circuit, and its oscillation frequency can be controlled by the voltage value of the control signal given to the voltage controlled oscillator (VCO).
Here, high-frequency (30 kHz) high-frequency alternating current is used as the alternating current. As this high-frequency alternating current, a frequency in the frequency range (20 kHz to 50 kHz) is used.
Then, here, a frequency fluctuation (FM modulation) of about 3 to 5 kHz is given above and below the high frequency (30 kHz) alternating current, and a sudden frequency fluctuation (shock wave is generated) is caused.

The control circuit 103 supplies the high-frequency oscillation circuit 102 with a control voltage for controlling the oscillation frequency. The control circuit 103 has a built-in random signal generator, and outputs a control signal whose voltage value changes according to the random signal generated by the random signal generator. The shift register 104 (SFR) has a 16-stage configuration, and the accumulated information can be read in parallel from terminals Q0 to Q15.
The shift operation of the shift register 104 is controlled by a shift pulse supplied from the pulse generator 105 (PG) to the terminal CK of the shift register 104. Further, the flip-flop 106 performs an inversion operation by the pulse of the pulse generator 105, and each time the flip-flop 106 inverts, the flip-flop 106 causes a sudden frequency fluctuation (generation of a shock wave) in the "I" portion shown in the frequency graph of FIG. ing.

The gate (GT) is a gate that performs the operation of exclusive OR, and acts as a match detection circuit. The result of the match detection by the gate (GT) is input to the 0th stage, which is the lowest from the terminal D of the shift register 104. Random number information is stored in the shift register 104 by sequentially shifting this information upward.

The random number information stored in the shift register 104 is taken out by a resistor from about half of the appropriately selected stages. The resistor r connects the terminals Q1, Q3, Q8, Q10, and Q12 to Q15 of each of these stages to a common connection point. This connection point is connected to a voltage controlled oscillator (VCO) that constitutes the high frequency oscillator circuit 102. On the other hand, the voltage controlled oscillator (VCO) is also connected to the flip-flop circuit 106 connected to the pulse generator 105.

Therefore, when the pattern of the random number information accumulated in each of these stages changes, the combined value of the resistors connected to the high level and the low level changes, respectively, and the voltage at the connection point fluctuates accordingly. Random signal is created. This operation can be reproduced by the CPU.

The pulse generator 105 is configured to send out a continuous pulse having, for example, 5 Hz as a center frequency, and change the repetition period of the pulse according to the voltage value of the signal input to the voltage controlled oscillator (VCO). The pulse generator 105 fluctuates the repetition period of the pulse according to the random signal from the shift register 104. The shift register 104 uses the output of the pulse generator 105 as a shift pulse.
Therefore, the control signal output to the voltage controlled oscillator (VCO) changes completely randomly in both the voltage value and the fluctuation period, and the flip-flop circuit 106 causes a sudden frequency fluctuation shown in FIG. 5 (b). (I) Part is being created.

In the power supply circuit described above, when the switch of the DC power supply 94 is turned on, a high frequency signal that changes randomly is given from the high frequency oscillation circuit 102 to the high frequency switching command circuit 101. When a random high-frequency signal is given to the high-frequency switching command circuit 101, a high-frequency switching command is issued from this and alternately given to the high-frequency switches 96a and 96b, and these high-frequency switches 96a and 96b are turned on and off in a high cycle. A randomly changing high-frequency alternating current is formed and alternately applied to the pair of electrode plates 52a and 52b of the second electrode 52 arranged in the water of the electrolytic tank 6.

In this way, the pair of high-frequency AC signals are applied to the electrode plates 52a and 52b of the second electrode 52, respectively, via electrical wiring, and the first electrode 50 and the third electrode 54 are in a grounded state. Is set to.
Although the first electrode 50 is a ground electrode, for example, a switching circuit 107 by a timer is provided, and the potential of the first electrode 50 is periodically changed from the ground potential to the potential to apply alternating current. It is also possible to remove the scale or the like adsorbed on the first electrode 50. In this case, the first electrode 50 may be simply rod-shaped (circular cross section), or the configuration of the pipe electrode material 56 may be used as an auxiliary. Here, the first electrode 50 is treated as a ground electrode.

Here, a method of attaching and detaching the pipe electrode material 56 and the like in the hydrogen water generator 2 will be described.
FIG. 6 shows a state in which the lid member 8 is opened. After a lapse of a predetermined period, the pipe electrode material 56, the third electrode 54, and the like are removed, and maintenance such as cleaning is performed. At the time of this attachment / detachment, the nut member 88 fixing the pipe electrode material 56 and the third electrode 54 and the like is loosened and removed from the screw portion 64 of the center electrode material 60 related to the first electrode 50. As a result, the third electrode 54 and the electrode holder 84 can be removed, and at the same time, the pipe electrode material 56 can be pulled out from the center electrode material 60 and removed. Further, the alloy plate case 82 is removed from the electrode holder 84.

In this way, the pipe electrode material 56, the third electrode 54, and the like can be easily removed only by removing the nut member 88 as the fastener. Then, foreign matter such as scale adhering to the pipe electrode material 56 is removed, and if necessary, the third electrode 54 is cleaned. Further, the alloy plate 80 in the alloy plate case 82 is replaced. In this case, the center electrode material 60 related to the first electrode 50 and the second electrode 52 are attached and fixed to the lid member 8.

After the maintenance, the pipe electrode material 56, the third electrode 54, and the like are attached. In these mountings, the pipe electrode material 56 is first fitted from the end portion (left end in the drawing) of the center electrode material 60. Then, the electrode holder 84 is arranged at these ends. The electrode holder 84 fits the through hole portion 86 into the pipe electrode material 56, and at the same time, fits the ends (left ends in the drawing) of the electrode plates 52a and 52b of the second electrode into the holding portion of the electrode holder 84. ..
The end portion (lower portion) of the second electrode 52 is held by the electrode holder 84, and the pipe electrode material 56 and the electrode plates 52a and 52b of the second electrode 52 are accurately connected by the interposition of the separation plate. Be quarantined.

Then, the tubular third electrode 54 is attached. In this case, the first electrode 50, the second electrode 52, the electrode holder 84, and the like are housed inside the third electrode 54, and are provided so as to cover the periphery of these electrodes and the like. Then, the upper cover material 71 of the tubular portion 70 of the third electrode 54 is pressed against the back surface portion 36 of the lid member 8 to be held, and the center of the bottom surface portion 72 from the insertion hole portion 74 to the first electrode 50. The screw portion 64 of the electrode material 60 is projected.

In this state, the upper portion of the third electrode 54 is held by the back surface portion 36 of the lid member 8. Since the lower end of the pipe electrode material 56 is in contact with the third electrode 54 and the pipe electrode material 56 is in contact with the center electrode material 60, the first electrode 50 and the third electrode 54 Is electrically conductive and integrated.
Then, the nut member 88 is tightened and screwed to the threaded portion 64 of the center electrode material 60 related to the first electrode 50, which protrudes from the insertion hole portion 74 of the third electrode 54. The nut member 88 can be manually tightened or loosened and removed from the screw portion 64. Further, the alloy plate case 82 containing the alloy plate 80 is held and fixed by inserting one end portion into the case holding portion of the electrode holder 84.

Further, by screwing and fixing the nut member 88 to the screw portion 64 of the center electrode material 60 related to the first electrode 50, the pipe electrode material 56, the third electrode 54 and the like are held, and these are the center electrode materials. It becomes a form fixed to 60. Further, the pipe electrode material 56 is held and fixed in a state of being fitted to the center electrode material 60. By screwing the nut member 88 into the threaded portion 64 of the center electrode material 60, this comes into contact with the bottom surface portion 72 of the third electrode 54, and the third electrode 54 and the first electrode 50 are in a conductive state. The electrodes are in a grounded state.
As described above, the pipe electrode material 56 related to the first electrode 50 can be easily attached and detached, and maintenance can be easily performed.

The control unit 12 of the hydrogen water generator 2 controls ON / OFF of the power switch, turns on / off the lamp, and manages the timer. The timer is provided here with timers of 60 minutes, 90 minutes, and 120 minutes. In addition, the control unit 12 automatically opens the lid member 8 of the hydrogen water generator 2 when energized, and when the electrodes or the like are pulled out of the water, or when the electrodes come into contact with each other (short circuit). It is controlled so that the energization is stopped.

Here, the pipe electrode material 56 related to the first electrode 50 was attached / detached by using the opening / closing mechanism of the lid member 8, but the following methods are also conceivable. For each of these methods, the configurations of the respective members (main body 4, lid member 8, electrode member 10, etc.) are the same except that the opening / closing mechanism of the lid member 8 is not used. Therefore, the same reference numerals are used for convenience. explain.

For example, the power feeding unit 14 and the control unit 12 may be provided inside the lid member 8. In this method, the main body 4 and the lid member 8 are separated from each other.
In this case, the lid member 8 is placed on the electrolytic cell 6 with the electrode member 10 attached to perform electrolysis. Then, when the electrolytic cell 6 is filled with raw water and when the pipe electrode material 56 related to the first electrode 50 is maintained, the lid member 8 is pulled upward and removed.
In this state, the pipe electrode material 56 is attached and detached. At this time, the lid member 8 is in a state where the electrode member 10 is directed upward, for example, and the pipe electrode material 56 and the like are attached and detached in the same manner as described above, and maintenance is performed.

Further, the main body 4 and the lid member 8 can be separated and both can be connected by an electric cable.
In this case, with the power supply unit 14 and the control unit 12 provided on the main body 4, the electrical connection between the power supply unit 14 and the electrode member 10 attached to the lid member 8 is extended from the power supply unit 14. This is done using the electric cable.

In this case, the connector attached to the end of the electric cable is inserted into the terminal provided on the lid member 8 and electrically connected. Then, the lid member 8 is detachably arranged on the upper part of the electrolytic cell 6, and electrolysis is performed with the connector connected to the terminal. Further, when the electrolytic cell 6 is filled with raw water and when the pipe electrode material 56 related to the first electrode 50 is to be maintained, the connector is removed from the terminal, and the lid member 8 is pulled upward to remove it. In this state, the pipe electrode material 56 and the like are attached and detached in the same manner as described above.
Even if these methods are used, the pipe electrode material 56 related to the electrode member 10 attached to the lid member 8 can be easily attached and detached, and maintenance such as removing the scale can be easily performed.

Here, a series of operations of the hydrogen water generator 2 and a method of using the hydrogen water generator 2 will be described. First, the lid member 8 is opened and opened, and the electrolytic cell 6 is taken out from the base 16 of the main body 4. Then, water such as tap water is poured into the electrolytic cell 6 and filled with about 5 liters of water.
When operating the hydrogen water generator 2, for example, a timer is set in order to specify the electrolysis time (reduction time). The operation of the device ends due to a timeout. Then, the hydrogen water (nanobubble hydrogen water) can be used for drinking or the like by opening the cock 27 attached to the electrolytic cell 6 and transferring it to a cup or the like.

When water is electrolyzed using the hydrogen water generator, scale (impurities such as silica) adheres to the pipe electrode material 56 or the like related to the first electrode 50 as a ground electrode, and the current value related to the electrodes is increased. It decreases and the processing efficiency deteriorates. Therefore, the pipe electrode material 56 is maintained (maintenance). In this case, since the scale does not adhere to the center electrode material 60 related to the first electrode 50, maintenance is substantially unnecessary.
The scale may adhere to the third electrode 54 to some extent, and the same maintenance is performed in this case as well. Maintenance is performed as appropriate depending on the degree of scale (impurities) adhering, although it depends on the usage time of the device.

In maintenance, if the nut member 88 attached to the lower part of the third electrode 54 by screwing is removed, the third electrode 54 and the electrode holder 84 can be easily removed as they are, and the center electrode material of the first electrode 50 can be removed. The pipe electrode material 56 fitted in the 60 can also be easily removed by pulling it out.
Then, using a brush, a detergent material, or the like, the scale adhering to the pipe electrode material 56 is removed and cleaned. At the same time, the tubular portion 70, the bottom surface portion 72, and the like of the third electrode 54 are also removed if there is adhesion of scale or the like. As described above, since the pipe electrode material 56, the third electrode 54, and the like can be easily removed, cleaning and the like are easy and contribute to workability.

Using the hydrogen water generator 2 according to this embodiment, with respect to the nanobubble hydrogen water generated by its electrolysis, the particle size of the bubble and the number (concentration) of the bubble (bubble) are outsourced to a private institution. Measurements were made.
FIG. 7 is graphs (A) and (B) showing the measurement results. In this graph, the horizontal axis shows the particle size (Size (nm)) of hydrogen bubbles, and the vertical axis shows the concentration (Concentration (Particles / ml)) as the number of particles (unit: E6). In this case, the time for electrolysis by the hydrogen water generator 2 was 2 hours, and the raw water (tap water) before electrolysis used was the same as it was without adding anything.

Here, the graph (A) is a graph showing the results of measurement immediately after the generation of the electrolyzed water (nanobubble hydrogen water) generated by the electrolysis of the hydrogen water generation device 2. Further, the graph (B) is a graph showing the measurement result one month after the generation. Although particles are present in raw water (tap water) before electrolysis, the particles in this case are fine dust and are different from bubbles.

In the graph (A) above, the particle size of the particles (air bubbles) ranges from 100 nm to 250 nm, and many nano-sized particles are observed. In particular, in the range of particle size of 120 nm to 220 nm, many such extremely fine nano-sized bubbles are generated.
It is generally known that the smaller the size of a bubble, the longer it takes to dissolve in water. Therefore, according to the hydrogen water generator 2, as shown in the graph (A), a large amount of fine nanobubble hydrogen water, that is, high-concentration nanobubble hydrogen water capable of long-term storage was produced.

The long-term storage is also supported by graph (B). That is, when the graph (A) immediately after the generation and the graph (B) one month later are compared, the difference (decrease) in the number of bubbles is slight, and the particle concentration is hardly reduced. From this, it can be seen that the hydrogen water generator 2 produced a large amount of fine and high-concentration nanobubble hydrogen water that can be stored for a long period of time.

On the other hand, in the electrolysis in the hydrogen water generator (FIG. 9) according to the conventional example, as shown in the graph (FIG. 10) of the measurement result, the particle diameter is around 200 nm in the state where the particle concentration is high.
Therefore, the hydrogen water produced by the hydrogen water generator according to the conventional example has a larger particle size than the hydrogen water produced by the hydrogen water generator 2 according to this embodiment, and as a result, the storage period is also long. It will be short.

As described above, the particle size of the nanobubble hydrogen water in the hydrogen water generator 2 according to this embodiment is finer than that in the hydrogen water generator according to the conventional example. (Details have not been clarified), narrowing the distance (L) between the electrodes, and making the first electrode 50 rod-shaped promotes and concentrates the electrolysis reaction. I guess it is.

In addition, the specific number of particles was measured by outsourcing to the private institution. As a result, as the number of particles (bubbles) generated by the hydrogen water generator 2 according to this embodiment (concentration: Concentration (Particles / ml)), the number of particles in 1 mL was measured after electrolysis. Weekly and 1 month later, respectively. The results of the measurement were 891 million pieces / mL after one week and 745 million pieces / mL after one month, respectively.
Therefore, the difference between the two was as small as 334 million (= 8.19-7.45), and it was confirmed that 90% or more remained. From now on, it is presumed that the hydrogen water generated by the hydrogen water generator 2 has a large number of bubbles (bubbles) having an extremely small particle size (nano bubbles), and therefore the storage period is long. ..

As described above, the number (concentration) of particles (concentration) generated by the electrolysis by the hydrogen water generator according to the conventional example was 559 million / mL. Further, in this case, the electrolysis time is 3 hours, which is 1 hour longer, and the raw water contains materials for increasing the conductivity. Therefore, in view of these, the number of nanobubble hydrogen water particles (bubbles) generated by the hydrogen water generator 2 according to this embodiment is substantially generated by the hydrogen water generator according to the conventional example. It is estimated that the amount of hydrogen generated is several times larger than the number of particles (bubbles) generated.

Further, regarding the number of particles of hydrogen bubbles in the electrolyzed water generated by the electrolysis of the hydrogen water generator 2 according to this embodiment, regarding the number of particles (concentration) of the bubbles (bubbles) after boiling the electrolyzed water. Similarly, another measurement was performed by outsourcing to a private institution.
As a result, the number of particles in 1 mL before boiling was 612 million particles / mL, and after boiling, it was 601 million particles / mL, which was hardly reduced, and about 98% remained. Was confirmed. From this, it can be said that the electrolyzed water generated by the electrolysis of the hydrogen water generator 2 can be used as nanobubble hydrogen water in ordinary cooking and the like, and can greatly contribute to practical use.

The substances contained in the particles (bubbles) generated by the hydrogen water generator 2 and the like have not been specifically measured, but from the electrolysis of water and the measurement of the amount of hydrogen in other tests. , It is presumed that most of them contain particles (bubbles) composed of hydrogen. From this, it is considered that the hydrogen water generator 2 produces a large amount of nano bubble hydrogen water in which hydrogen is contained in nano-sized bubbles.

Further, it has been confirmed that the hydrogen water generator 2 generates a small amount of chlorine even when tap water or the like is used. According to an in-house test, this hydrogen water generator 2 had about half the amount of free chlorine (mg / L) as compared with the hydrogen water generators of other companies. It is considered that the decrease in the amount of free chlorine is due to the fact that the third electrode 54 is composed of a tubular net body and the surface area thereof is increased.

FIG. 8 shows the arrangement mode of the third electrode 54 with respect to the hydrogen water generation device 2 according to this embodiment. Since the third electrode 54 is formed by molding a flat net into a cylindrical shape, there is a caulking portion 58 that connects the ends in a caulked state as a seam thereof. Therefore, it was confirmed whether the arrangement position of the caulking portion 58 has an influence on the generation of hydrogen water by electrolysis.

Specifically, the position of the crimped portion 58 of the third electrode 54 is changed with respect to the second electrode 52 in which the alloy plate 80 (held by the alloy plate case 82) is arranged on the outside, and hydrogen water at that time is changed. The state of occurrence of was measured. The position of the crimped portion 58 is based on the direction of the center position of the second electrode 52 in which the alloy plate 80 is arranged on the outside when viewed from the first electrode 50 (the angle of the crimped portion 58 is 0 °).
Here, (a) the net electrode 0 ° has the same angle of the crimped portion 55, (b) the net electrode 30 ° has the same angle of 30 °, and (c) the net electrode 90 ° has the same angle of 90 °, (d). ) The net electrodes 180 ° have the same angle of 180 °.

As a result of the measurement, after electrolysis is performed at each net electrode angle by the hydrogen water generator 2, the supernatant of the electrolyzed water in the electrolytic cell 6 after operation is collected, or the electrolyzed water after stirring is collected and each hydrogen concentration ( ppb) was measured. The results are as follows.
After the operation of (a), the supernatant (513ppb) and stirring (313ppb).
After the operation of (b), the supernatant (364 ppb) and stirring (282 ppb).
After the operation of (c), the supernatant (381ppb) and stirring (254ppb).
After the operation of (d), the supernatant (440 ppb) and stirring (301 ppb).
As a result, it was confirmed that the hydrogen concentration was higher in each angle of (a) net electrode 0 ° and (d) net electrode 180 ° than in other angles.
Therefore, when forming the hydrogen water generator 2, it is preferable to adopt the form of (a) net electrode 0 ° and (d) net electrode 180 ° as the arrangement form of the third electrode 54. There is.

Usually, most of the hydrogen dissolved in water is released into the air over time, and usually dissolves only for a few days. However, it is known that nanobubbled hydrogen is dissolved in water for a long time. Most of the hydrogen water generated by electrolysis by the hydrogen water generator 2 is dissolved in water as nanobubbled nanobubble hydrogen water, and therefore the effect is maintained as hydrogen water that can be stored for a long period of time. Therefore, it can be stored and managed with peace of mind, and it can be expected to be effective as hydrogen water that is also excellent in practical use.

In addition, the hydrogen water generated by the hydrogen water generator 2 has been confirmed to have a wide range of effects such as human health maintenance and beauty, and also contributes to the reduction of livestock diseases and odors, the growth of plants, and the promotion of growth. It is also expected to do things.
When water is electrolyzed, oxygen gas is generated from the anode to generate a part of oxygen water, but a certain effect has been confirmed for oxygen water, and it can be drunk like hydrogen water. be.

As described above, according to the hydrogen water generator 2 according to this embodiment, a large amount of very fine nanobubble hydrogen water is generated, so that the hydrogen water can be stored for a long period of time and is practically large. It has the excellent effect of contributing. At the same time, the electrode members, especially the pipe electrode material that requires maintenance, can be easily attached and detached, and the electrodes can be easily cleaned by removing impurities such as scales, and the maintainability is improved. As a result, the electrical conduction characteristics of the electrodes are maintained in good condition, which contributes to electrolysis and leads to the mass production of nanobubble hydrogen water. As described above, the electrolysis by the hydrogen water generator 2 has made it possible to generate a large amount of high-concentration nanobubble hydrogen water that can be stored for a long period of time.
