FIG. 9 is a cross-sectional view taken along line IX-IX in FIG.

  1 to 9, the longitudinal direction of the hydrogen water generator is the X direction, and the directions orthogonal to the X direction and also orthogonal to each other are the Y direction and the Z direction. Thereby, the top view of the hydrogen water generator 10 is a YZ plane view, and the front view is an XY plane view.

  As can be seen from FIGS. 1 to 3, the overall shape of the hydrogen water generator 10 according to the present embodiment is a cylindrical shape. The hydrogen water generator 10 includes a main body portion 11 and a lid portion 12. When the hydrogen water generator 10 is not used, the lid portion 12 is fitted so as to cover the distal end portion of the main body portion 11. The tip portion is protected from external force or the like. Further, the main body 11 is provided with a switch 13 for driving the hydrogen water generator 10 and a notification unit 14 for notifying that the generation of hydrogen water is completed.

  As can be seen from FIGS. 4 and 5, when the lid 12 is removed from the main body 11, the hydrogen generator generates hydrogen by dipping in water from one end of the main body 11 (the bottom side opposite to the upper surface). 21 is disposed, and the hydrogen generation part 21 extends in the X direction. Further, as can be seen from FIGS. 4 to 6, the hydrogen generation unit 21 is formed so as to surround an electrode unit 25 including two cathodes 22 and 23 and one anode 24 and a peripheral region of the electrode unit 25. And a fixing member 27 for fixing the electrode portion 25 in the protection member 26.

  The cathodes 22, 23 and the anode 24 are cylindrical rod-shaped bodies, and have a structure in which platinum (Pt) is coated on the surface of a metal rod made of titanium (Ti). That is, each electrode has a two-layer structure in which a platinum layer is laminated on a titanium layer. The shapes of the cathodes 22 and 23 and the anode 24 are not limited to the rod-shaped body, and may be other shapes such as a plate shape or a prism shape.

  The anode 24 may be composed of only a titanium layer (that is, a titanium metal rod) without forming a platinum layer. In the present embodiment, the cathodes 22 and 23 and the anode 24 have the same structure from the viewpoint of reducing manufacturing costs and facilitating assembly work. Further, the materials of the cathodes 22 and 23 and the anode 24 are not limited to titanium and platinum, and must not generate gas or organic matter that adversely affects the human body in the water in which the electrode unit 25 is immersed. Other metals can also be used. For example, the surface layer portion may be coated with a platinum-based film or magnesium hydride using a titanium alloy, magnesium, or the like. Alternatively, the cathodes 22, 23 and the anode 24 may be made of platinum (Pt) / iridium (Ir) (platinum). It may have a structure in which a thin film and a film made of an iridium thin film) and a mixture thereof (a film formed by mixing platinum and iridium) are coated. That is, each electrode may have a two-layer or three-layer structure in which a layer of platinum (Pt) / iridium (Ir) and a mixture thereof is laminated on a titanium layer.

  In this embodiment, an acrylic resin is used as the material for the protective member 26. The reason for using the acrylic resin is that it has excellent heat resistance and does not generate gas or organic matter that adversely affects the human body even when immersed in cold water or hot water. The material of the protective member 26 is not limited to acrylic resin, and has excellent heat resistance, and does not generate gas or organic matter that adversely affects the human body even when immersed in cold water or hot water. Other materials can be used as long as they are suitable. For example, general-purpose polystyrene (GPPS) may be used.

  Further, as shown in FIG. 6, by joining the first resin molded body 31 and the second resin shaped body 32 constituting the protective member 26, the bowl-shaped protective member 26 is assembled. Here, without using an adhesive for joining the first resin molded body 31 and the second resin molded body 32, for example, a concave portion is provided in the first resin molded body 31, and a convex portion is provided in the second resin molded body 32, The first resin molded body 31 and the second resin molded body 32 are joined by fitting the projection into the recess. The reason for using such a joining method is to prevent the adhesive and the like from being dissolved in water and adversely affecting the human body.

  As can be seen from FIGS. 6 to 8, the first resin molded body 31 has three through holes 33 into which the electrode portions 25 are inserted and three threaded holes into which screws for connecting to the main body portion 11 are inserted. A main support portion 35 formed with 34, five sub-support portions 37 each having an outer shape substantially disk-shaped and having three through holes 36 through which the electrode portion 25 is passed, and an arc shape and a lattice shape. And a first collar portion 38. On the other hand, the 2nd resin molding 32 is comprised only from the 2nd collar part 39 formed in arc shape and a grid | lattice form.

  In the first resin molded body 31, the main support portion 35 and the five sub-support portions 37 are arranged in a row in the insertion direction of the electrode portion 25, and the through hole 33 and the through hole 36 are in the insertion direction of the electrode portion 25. They are arranged so as to overlap. Thereby, the cylindrical cathodes 22 and 23 and the anode 24 can be inserted straight, and one end of the electrode part 25 can be supported by the fixing member 27.

  Further, as can be seen from FIG. 7, an equilateral triangle is formed by a line segment connecting the three through holes 33 in the main support portion 35, and one side of the equilateral triangle is about 4 cm. Similarly, an equilateral triangle is also formed by a line segment connecting the three through holes 36 in the sub-supporting portion 37, and one side of the equilateral triangle is about 4 cm. That is, on the respective planes of the main support portion 35 and the sub support portion 37, the through hole 33 and the through hole 36 are positioned at the apex portion of an equilateral triangle having a side of 4 cm. Due to the arrangement of the through holes 33 and the through holes 36, the cathodes 22, 23 and the anode 24 are spaced apart from each other at equal intervals (4 cm).

  The first flange portion 38 extends along the extending direction (that is, the X direction) of the electrode portion 25, and has a main line portion 38a that is formed in an arc shape with a curved tip portion (+ X side), and a YZ plane. It is comprised from the subline part 38b currently formed in the arc shape inside. Here, the above-described sub-supporting portions 37 are arranged on every other side of the sub-line portion 38b. Similarly, the second flange portion 39 extends along the extending direction of the electrode portion 25 (that is, the X direction) and has a main line portion 39a that is formed in an arc shape with a curved tip portion (+ X side). And a sub-line portion 39b formed in an arc shape in the YZ plane.

  And when joining the 1st resin molding 31 and the 2nd resin molding, while joining the main line part 38a of the 1st collar part 38, and the main line part 39a of the 2nd collar part 39, it is the 1st collar part. The side surface of the sub support part 37 located inside the sub line part 38b of 38 is joined so that it may surround with the inner surface of the sub line part 39b of the 2nd collar part 39. FIG. As a result, the sub-supporting portion 37 having the through hole 36 is positioned inside the collar portion (the first collar portion 38 and the second collar portion 39) formed in a lattice shape, and is inserted into the through hole 36. The electrode portion 25 is surrounded by the protective member 26. With such a structure, even if the user of the hydrogen water generator 10 is in a state where a voltage is applied to the electrode unit 25, it is prevented that the electrode unit 25 is accidentally contacted to cause an electric shock or the like. Yes.

  The number of sub-supporting portions 37 is not limited to five. For example, the number of sub-supporting portions 37 may be formed in the inner portion of all the sub-line portions 38b, and the number thereof may be reduced. Further, the numbers of the main line portions 38a and 39a and the sub line portions 38b and 39b are not limited to the numbers shown in FIG. 6 (three main line portions and nine sub line portions each). Adjustment can be made as appropriate as long as the user of the generator 10 cannot touch the electrode unit 25. That is, if it is possible to prevent the user of the hydrogen water generator 10 from touching the electrode portion 25, the lattice shape of the protective member 26 is changed as appropriate (for example, the lattice shape is made finer or coarser). )can do.

  As shown in FIGS. 4 and 5, the fixing member 27 is attached to the surface of the sub-supporting portion 37 provided at the position farthest from the main supporting portion 35 (that is, located on the + X side). The fixing member 27 may be formed integrally with the sub-supporting portion 37, or the convex portion formed on the surface of the fixing member 27 may be fitted into the concave portion of the sub-supporting portion 37 and fixed. As shown in FIG. 4, the planar shape of the fixing member 27 (the shape in the YZ plane) is a substantially triangular shape (the outer shape is generally triangular, but the shape of each vertex and each side is curved), and the main support portion It functions so as to close one end of the through hole 36 of the sub-supporting portion 37 provided at the position farthest from the 35. That is, the fixing member 27 functions as a stopper for preventing the cathodes 22 and 23 and the anode 24 from falling off from the through holes 36 of the sub-supporting portion 37 provided at the position farthest from the main supporting portion 35. The cathodes 22, 23 and the anode 24 are fixed.

  In addition, since the main support part 35 is attached to the main body part 11 at the end of the electrode part 25 located on the main support part 35 side, the electrode part 25 may fall off from the main support part 35 side due to the presence of the main body part 11. Absent. From the above, in the present embodiment, the support member that supports the electrode portion 25 is configured by the fixing member 27 and the housing portion of the main body portion 11, and the electrode portion 25 is supported. The electrode part 25 may be supported on the main body part 11 by a support structure.

  The dimension of the electrode part 25 and the protection member 26 in the X direction can be set according to a container of water (for example, a plastic bottle, a bottle, etc.) in which the electrode part 25 and the protection member 26 are immersed. Since the hydrogen water generator 10 according to the present embodiment is assumed to be used for a 500 ml PET bottle, the dimension in the X direction of the electrode portion 25 and the protection member 26 is about 13 cm.

  As shown in FIG. 9, the switch 13 and the notification unit 14 are provided inside the main body 11 in a state of being mounted on the mounting substrate 44. In the main body 11, a battery box 41, a dry battery 42 stored in the battery box 41, and a control circuit 43 positioned between the battery box 41 and the main support portion 35 are provided.

  The switch 13 is a general on / off switch. When the switch 13 is turned on, the battery voltage of the dry battery 42 is supplied to the control circuit 43. In this embodiment, the switch 13 is a button type switch, and when the switch 13 is pressed once from the non-driven state of the hydrogen water generator 10, the hydrogen water generator 10 is turned on. By pressing once, the hydrogen water generator 10 is turned off.

  The notification unit 14 includes a light emitting diode (LED) 14a (LED: Light Emitting Diode) and a lid 14b that covers the LED 14a. The LED 14a lights or blinks to notify the completion of the generation of hydrogen water. Specifically, the notification unit 14 emits light according to the drive voltage of the LED 14 a that is a notification signal supplied from the control circuit 43. Here, various LEDs such as a blue LED, a red LED, a green LED, or a white LED can be used as the LED 14a.

  In the hydrogen water generator 10 of the present embodiment, three dry batteries 42 are stored in the battery box 41. That is, the hydrogen water generator 10 is driven by a relatively low voltage of 4.5 V without using a household AC power source. For this reason, in the hydrogen water generator 10 of a present Example, the circuit and apparatus which process an alternating current power supply etc. become unnecessary, and cost reduction and size reduction of the hydrogen water generator 10 itself can be achieved easily. . The dry battery 42 may be a single-use primary battery or a rechargeable secondary battery (storage battery). Further, a button battery may be used instead of the dry battery 42. That is, in the hydrogen water generator 10 of the present invention, various small batteries (primary battery, secondary battery) that do not affect the carrying of the hydrogen water generator 10 by appropriately adjusting the battery box 41 and the control circuit 43. Can be used.

  The control circuit 43 is an integrated circuit including a general central processing unit. The control circuit 43 is driven according to the on / off operation of the switch 13. Specifically, the battery voltage 4.5 V is supplied from the dry battery 42 to the control circuit 43 as the switch 13 is turned on. Here, the control circuit 43 includes a booster circuit, boosts the battery voltage 4.5V supplied from the dry battery 42 to a boosted voltage of 5V to 36V, and supplies the boosted voltage to the electrode unit 25. Therefore, in the hydrogen water generator 10 of the present embodiment, the potential difference between the cathodes 22 and 23 and the anode 24 is 5V to 36V.

  Further, the control circuit 43 is driven based on the battery voltage supplied from the dry battery 42 and measures the elapsed time from the start of supply of the boosted voltage to the electrode unit 25. Then, the control circuit 43 supplies a notification signal corresponding to the elapsed time to the notification unit 14. For example, when the supply of the boosted voltage to the electrode unit 25 is started, the control circuit 43 supplies a notification signal that causes the notification unit 14 to blink, and when 3 minutes have elapsed from the start of the supply of the boosted voltage, In order to notify that the generation has been completed, a notification signal for turning on the notification unit 14 is supplied to the notification unit 14. In this case, the control circuit 43 changes the blinking cycle (lit state, unlit state, and cycle) of the notification unit 14 from the start of blinking of the notification unit 14 to the lighting of the notification unit 14, and the lighting state time at the time of blinking May be gradually increased so that it is always lit after 3 minutes from the start of supply of the boosted voltage. By such an operation of the control circuit 43, the user of the hydrogen water generator can easily recognize that the hydrogen water is almost complete and that the production of the hydrogen water has been completed. Note that hydrogen is generated from the start (start of supply of the boosted voltage), and the time (set time) until hydrogen water completion can be set between 30 seconds and 10 minutes depending on the concentration and conditions.

  As shown in FIG. 9, a cavity 12a larger than the outer shape of the protection member 26 is formed inside the lid portion 12, and the protection member 26 is accommodated in the cavity 12a. Further, a part of the outer surface of the lid part 12 is threaded, and a part of the inner surface of a part of the main body part 11 is also threaded. For this reason, when attaching the lid part 12 to the main body part 11, the lid part 12 can be easily pushed into the main body part 11 by rotating the lid part 12 so that the lid part 12 is screwed into the main body part 11. 12 can be attached to the main body 11, and the electrode 25 and the protective member 26 can be protected from external force or the like.

(How to use hydrogen water generator)
Next, a method for using the hydrogen water generator 10 according to the present embodiment and a hydrogen water generation process will be described with reference to FIGS. 10 to 14. FIG. 10 is a surface view showing a usage state of the hydrogen water generator 10 according to the present embodiment. FIG. 11 is a block diagram of the hydrogen water generator 10 according to the present embodiment. FIG. 12 to FIG. 14 are schematic views in water for explaining each generation process until hydrogen water is generated.

  First, when the hydrogen water generator 10 according to the present embodiment is used, the lid portion 12 is removed and the hydrogen generating portion 21 that is the tip portion of the main body portion 11 is immersed in water. As described above, since the hydrogen water generator 10 according to the present embodiment is designed for a commercially available 500 ml PET bottle, as shown in FIG. 21 is inserted, and the hydrogen generator 21 is immersed in the water in the PET bottle 51. Here, since the diameter of the casing portion to which the protection member 26 of the main body portion 11 is attached is larger than the opening diameter of the plastic bottle 51, the casing portion of the main body portion 11 becomes the drinking mouth portion of the plastic bottle 51. It will abut.

  In FIG. 10, the hydrogen water generator 10 is positioned above the PET bottle 51, but the positions of the PET bottle 51 and the hydrogen water generator 10 may be switched so that water does not leak. Good. That is, the use of the hydrogen water generator 10 may be started with the hydrogen water generator 10 inserted from below the PET bottle 51. Even in such a case, the casing portion of the main body 11 comes into contact with the drinking mouth portion of the plastic bottle 51 and closes the drinking mouth portion, so that water does not leak.

  Next, by turning on the switch 13, a battery voltage of 1.5 V is supplied from the dry battery 42 to the control circuit 43. Subsequently, the booster circuit in the control circuit 43 boosts the battery voltage to generate a boosted voltage of 12V to 18V, for example. The control circuit 43 supplies the boosted voltage to the electrode unit 25. Thereby, generation of hydrogen is started in the water in the plastic bottle 51. Note that the numerical value of the boosted voltage can be appropriately changed according to the required conditions such as the amount of hydrogen generated.

  Here, the control circuit 43 intermittently supplies the boosted voltage to the electrode unit 25. For example, supply and non-supply of the boost voltage are repeated every 5 to 20 ms, and the boost voltage is supplied at a constant cycle. By performing such control, the temperature rise in the electrode part 25 can be suppressed, and the hydrogen generation efficiency in the electrode part 25 can be improved.

  In addition, the control circuit 43 supplies a notification signal to the notification unit 14 and causes the notification unit 14 to blink. Thereby, the user of the hydrogen water generator 10 can easily recognize that the hydrogen water generator 10 has been driven and generation of hydrogen water has started.

Next, as shown in FIG. 12, when the supply of the intermittent boosted voltage is started, the water 52 in the PET bottle 51 is electrolyzed, and hydrogen ions (H ⁺ ) 53 and hydroxide ions ((OH ⁻ )). (Not shown) will occur. Moreover, as shown in FIG. 12, the mineral ion 54 is contained in the water 52 which is a commercially available mineral water. Here, the mineral ions are cations such as sodium, calcium, magnesium, vanadium, and the like.

  By continuing to supply the intermittent boosted voltage described above, the hydrogen ions 53 are attracted to the cathode 22 and the mineral ions 54 are also attracted to the cathode 22. At this time, since the boosted voltage is intermittently supplied, the temperature rise at the cathode 22 is suppressed, and the hydrogen ions 53 and the mineral ions 54 can be efficiently attracted to the cathode 22. Note that hydroxide ions are attracted to the anode 23.

  Next, as shown in FIG. 13, the hydrogen ions 53 collected at the cathode 22 receive electrons from the cathode 22 and exist around the cathode 22 as hydrogen atoms 55. The mineral ions 54 also receive electrons from the cathode 22 and exist around the cathode 22 as mineral atoms 56 (shown in FIG. 14).

Here, in general, the hydrogen atoms 55 are vaporized as hydrogen molecules (H ₂ ) by being bonded to each other, and are difficult to dissolve in the water 52. However, in this embodiment, as shown in FIG. 14, hydrogen atoms 55 and mineral atoms 56 are easily combined with platinum constituting the cathode 22 as a catalyst. That is, at least one or more hydrogen atoms 55 are occluded in the mineral atoms 56. Specifically, a hydrogen compound such as sodium hydride (NaH), calcium hydride (CaH ₂ ), or potassium hydride (KH) is generated at the cathode 22. Thereby, the vaporization of hydrogen can be prevented, and hydrogen can be dissolved in the water 52 for a long time. Such a technique is referred to as “hydrogen encapsulation technology”.

  On the other hand, the hydroxide ions gathered at the anode 23 are vaporized as oxygen molecules 57 by passing electrons to the anode 23. The hydroxide ions also change to water 52 by passing electrons to the anode 23.

  Then, after 3 minutes have elapsed from the supply of the boosted voltage to the electrode unit 25, the control circuit 43 supplies a notification signal to the notification unit 14 and turns on the notification unit 14. Thereby, the user of the hydrogen water generator 10 can easily recognize that the generation of the hydrogen water has been completed.

  Note that the intermittent supply of the boosted voltage in the control circuit 43 is not limited to the above-described supply and non-supply, and includes the supply of the boosted voltage with voltage waveforms as shown in FIGS. . Here, each of FIG. 15 thru | or FIG. 17 shows an example of the voltage waveform used in the hydrogen water generator 10 which concerns on an Example. Hereinafter, voltage supply using a special voltage waveform will be described with reference to FIGS. 15 to 17.

  As shown in FIG. 15, the voltage waveform of the boosted voltage supplied from the control circuit 43 to the electrode unit 25 is, for example, a first voltage supply period that is one second for supplying voltage at 6 V (first voltage value), 4 Periodically, a second voltage supply period of 0.5 seconds for supplying voltage at 5 V (second voltage value) and a third voltage supply period of 1 second for supplying voltage at 5 V (third voltage value). It is formed in combination. Here, in the first voltage supply period, since the supply voltage value is fixed at 6V, the average supply voltage value in the first voltage supply period is 6V which is the first voltage value. Similarly, in the second voltage supply period, since the supply voltage value is fixed at 4.5V, the average supply voltage value in the second voltage supply period becomes 4.5V which is the second voltage value, and the third voltage In the supply period, since the supply voltage value is fixed at 5V, the average supply voltage value in the third voltage supply period is 5V, which is the third voltage value.

  By performing voltage supply with such a voltage waveform, even if the temperature of the electrode unit 25 increases due to voltage supply in the first voltage supply period, voltage supply is performed in the second voltage supply period and the third voltage supply period. The temperature of the electrode part 25 can be lowered by lowering. Thereby, the temperature rise of the electrode part 25 is suppressed, the generation efficiency of hydrogen in the cathodes 22 and 23 is improved (that is, the generation amount of hydrogen is increased), and the generation of ozone in the anode 24 can be suppressed.

  Further, in the step-up voltage supply using such a voltage waveform, the voltage value changes from the lowest voltage value (4.5 V: second voltage value) to the highest voltage value (6 V: first voltage value) within the voltage supply period. , Stepwise via an intermediate voltage value (5 V: third voltage value). Thereby, the temperature rise of the electrode part 25 can be suppressed favorably, maintaining the voltage value required for electrolysis, and generation | occurrence | production of the hydrogen in the cathodes 22 and 23 can be improved further.

  Furthermore, in the step-up voltage supply using such a voltage waveform, the difference (1 V) between the maximum voltage value (6 V: first voltage value) and the intermediate voltage value (5 V: third voltage value) within the voltage supply period is The voltage is set to twice the difference (0.5 V) between the intermediate voltage value (5 V: third voltage value) and the lowest voltage value (4.5 V: second voltage value) within the voltage supply period. By performing such voltage control, the temperature increase of the electrode portion 25 can be further suppressed while maintaining the voltage value necessary for electrolysis, and the generation of hydrogen at the cathodes 22 and 23 is further suppressed. Can be improved.

  Other voltage waveforms as shown in FIG. 16 are, for example, a first voltage supply period of 2 seconds for supplying voltage at 6 V (first voltage value), and 0 for supplying voltage at 3 V (second voltage value). The second voltage supply period of 5 seconds is periodically combined. Here, in the first voltage supply period, since the supply voltage value is fixed at 6V, the average supply voltage value in the first voltage supply period is 6V which is the first voltage value. Similarly, in the second voltage supply period, since the supply voltage value is fixed at 3V, the average supply voltage value in the second voltage supply period is 3V, which is the second voltage value.

  Further, in another voltage waveform as shown in FIG. 17, for example, in a sine wave with 5V as a reference of amplitude, a portion that protrudes downward at a frequency of once every two periods is changed to be upward. . More specifically, when the voltage supply is started, the first 1 second (0 to 1 second), the next 1 second (1 to 2 seconds), and the next 1 second (2 to 3 seconds). ) Is a graph that protrudes upward, and further continues for 1 second (from 3 seconds to 4 seconds) and becomes a graph that protrudes downward, and the change from 1 second to 4 seconds is repeated periodically thereafter. That is, the voltage waveform in FIG. 17 is a first voltage supply period of 3 seconds in which the voltage value is changed by changing the voltage value at 5 V or more, and 1 second in which the voltage value is changed by changing the voltage value at 5 V or less. It is formed by periodically combining the second voltage supply periods. Here, both amplitudes (difference between the maximum voltage value and the minimum voltage value) of the voltage waveform are about 3 to 5 V, the average supply voltage value in the first voltage supply period is about 6 V, and in the second voltage supply period. The average supply voltage value is about 4V.

  By performing voltage supply using these voltage waveforms, even if the temperature of the electrode unit 25 increases with the voltage supply during the first voltage supply period, the voltage supply during the second voltage supply period is decreased to decrease the electrode unit 25. The temperature can be lowered. Thereby, the temperature rise of the electrode part 25 is suppressed, the generation efficiency of hydrogen in the cathodes 22 and 23 is improved (that is, the generation amount of hydrogen is increased), and the generation of ozone in the anode 24 can be suppressed.
