The anode part 11, the cathode part 12, and the insulator 13 are all net-like members. Detailed shapes of the anode part 11, the cathode part 12, and the insulator 13 will be described later.

  As shown in FIG. 2, the electrode part 10, more specifically, the anode part 11 and the cathode part 12 have end part side openings 10HA and 10HB at both ends, respectively. The electrode part 10 may not have the edge part side opening part 10HA and 10HB, and may have the edge part side opening part 10HA or the edge part side opening part 10HB in at least one edge part.

  The anode 11 is electrically connected to the anode power supply member 14 that is a rod-shaped conductor in the end-side opening 10HA. The cathode portion 12 is electrically connected to a cathode power supply member 15 that is a rod-shaped conductor in the end portion side opening 10HA. As shown in FIG. 1, the anode power supply member 14 is electrically connected to the anode of the power supply unit 20. The cathode power supply member 15 is electrically connected to the cathode of the power supply unit 20. With such a structure, the anode part 11 is electrically connected to the anode of the power supply part 20 via the anode power supply member 14, and the cathode part 12 is connected to the cathode of the power supply part 20 via the cathode power supply member 15. Electrically connected. However, the anode power supply member 14 does not have to have such a rod-like shape, and can have an arbitrary shape. Further, the anode power supply member 14 is not limited to being connected to the anode portion 11 in the end portion side opening 10HA, and the connection portion is arbitrary as long as it is electrically connected to the anode portion 11 as a conductor. Similarly, the cathode power supply member 15 does not have to have such a rod-like shape, and can have any shape. The cathode power supply member 15 is not limited to being connected to the cathode portion 12 in the end portion side opening 10HA, and the connection portion is arbitrary as long as it is electrically connected to the cathode portion 12 as a conductor.

  The anode portion 11 has a slit 11SL that extends in the longitudinal direction E, that is, the direction in which the anode portion 11 that is a cylindrical member extends. The cathode portion 12 has a slit 12SL that extends in the longitudinal direction E, that is, the direction in which the cathode portion 12 that is a cylindrical member extends.

The restraining member 40 closes the slit 11SL of the anode part 11 and the slit 12SL of the cathode part 12, and restrains the cathode part 12, the insulator 13, and the anode part 11 from the circumferential direction of the cathode part 12 and the anode part 11. In the present embodiment, two restraining members 40 are provided, but the number is arbitrary.

  As shown in FIG. 1, the electrode part 10 is attached to the attachment part 2 in the end part side opening part 10HA. The electrode portion 10 has an end-side opening 10HA housed inside the attachment portion 2 and extends from the fixing portion 4 in a direction away from the attachment portion 2.

  The power supply unit 20 is a power supply that generates a DC voltage. As shown in FIG. 1, the power supply unit 20 is housed inside the attachment unit 2. As described above, the power supply unit 20 has the anode side electrically connected to the anode power supply member 14 and the cathode side electrically connected to the cathode power supply member 15. When the electrode unit 10 is disposed in the liquid 100, the power source unit 20 electrolyzes the liquid 100 by applying a DC voltage to the electrode unit 10. At this time, a current flows through the liquid 100.

  The control unit 21 controls application of a DC voltage by the power supply unit 20. The control unit 21 includes an operation unit, and causes the power supply unit 20 to start applying a DC voltage when the user operates the operation unit. In addition, the control unit 21 stops the application of the direct current when a predetermined time has elapsed since the power supply unit 20 started applying the direct current voltage.

  As shown in FIG. 1, the rotating unit 30 includes a drive unit 31, a shaft unit 32, and a stirring unit 33. In the rotating unit 30, the driving unit 31 is electrically connected to the power supply unit 20. The rotating unit 30 rotates the stirring unit 33 when the driving unit 31 rotates the shaft unit 32 when a DC voltage is applied from the power supply unit 20. The rotating unit 30 stirs the liquid 100 when the stirring unit 33 is placed in the liquid 100 and rotated by the driving unit 31.

  The drive unit 31 is a DC motor. The drive unit 31 converts the drive voltage applied from the power supply unit 20 into a rotational motion and transmits it to the shaft unit 32. The driving unit 31 may be applied with a driving voltage from another power source instead of the power source unit 20. Moreover, the drive part 31 is not restricted to a direct current motor, What is necessary is just to convert a drive voltage into a rotational motion and to transmit to the shaft part 32.

  The shaft portion 32 is an axial member connected to the drive portion 31. One end portion 32 a of the shaft portion 32 is connected to the drive portion 31. The shaft portion 32 penetrates the inside 52 of the anode portion 11 and extends in a direction away from the attachment portion 2 from one end portion 32a toward the other end portion 32b. Further, the other end 32 b of the shaft portion 32 is exposed from the inside 52 of the anode portion 11 to the outside along the longitudinal direction E (a direction away from the attachment portion 2). The shaft portion 32 rotates when one end portion 32 a is rotationally driven by the drive portion 31.

  Bearing portions 35a and 35b are provided in the interior 52 of the anode portion 11 at the positions of the end side openings 10HA and 10HB, respectively. The bearing portions 35a and 35b are cylindrical slide bearings. The bearing portions 35a and 35b are fixed to the outer peripheral portion 35o and the inner peripheral portion 11Si of the anode portion 11. The shaft portions 32 are penetrated through the bearing portions 35a and 35b. That is, the bearing portions 35 a and 35 b are fixed to the anode portion 11, but are not fixed to the shaft portion 32. Therefore, although the shaft part 32 is rotated by the drive part 31, the electrode part 10 including the anode part 11 is not rotated.

  The shaft portion 32 rotates around the rotation axis AX1 which is the central axis of the shaft portion 32 in the inside 52 of the anode portion 11 with the bearing portions 35a and 35b as bearings. Here, the rotation axis AX1 of the shaft portion 32 and the axis along the longitudinal direction E of the electrode portion 10 are parallel to each other. More specifically, the electrode portion 10 has a central axis AX2 along the longitudinal direction E. The rotation axis AX1 of the shaft portion 32 and the central axis AX2 of the electrode portion 10 are parallel to each other. More specifically, the rotation axis AX1 of the shaft portion 32 and the center axis AX2 of the electrode portion 10 coincide with each other.

  FIG. 3 is a perspective view showing the structure of the stirring unit according to the present embodiment. As shown in FIG. 3, the stirring unit 33 includes a truncated cone part 37 having a truncated cone shape and a groove part 38. The truncated cone portion 37 includes a side surface 37a, a long diameter side end portion 37b that is an end portion on the long diameter side, and a short diameter side end portion 37c that is an end portion on the short diameter side. The groove portion 38 is a groove provided on the side surface 37 a of the truncated cone portion 37 from the long diameter side end portion 37 b to the short diameter side end portion 37 c. In the present embodiment, eight groove portions 38 are provided on the side surface 37 a along the circumferential direction of the truncated cone portion 37, but the number thereof is arbitrary.

  As shown in FIG. 1, the stirring part 33 is attached to the other end part 32b of the shaft part 32 at the long diameter side end part 37b. In other words, the stirring unit 33 is located in the end side opening 10HB of the electrode unit 10. The stirring portion 33 is attached coaxially with the shaft portion 32. The stirring unit 33 is rotated by the drive unit 31 via the shaft unit 32. Since the stirring unit 33 is attached coaxially with the shaft unit 32, the stirring unit 33 rotates around the rotation axis AX1 of the shaft unit 32. The rotation axis AX1 that is the rotation center of the stirring unit 33 coincides with the center axis AX2 of the electrode unit 10. That is, the electrode part 10, the shaft part 32, and the stirring part 33 are arrange | positioned coaxially.

  The stirring unit 33 is placed in the liquid 100 and is rotated by the driving unit 31 to generate a water flow and stir the liquid 100. In addition, since the groove part 38 is provided along the short diameter side edge part 37c from the long diameter side edge part 37b, it can generate | occur | produce a water flow suitably, However, What produces a water flow by rotating the stirring part 33? If so, the shape is arbitrary.

  Next, the electrolysis of the liquid 100 by the electrode unit 10 will be described. FIG. 4 is a schematic diagram illustrating the electrolysis of the liquid by the electrode unit according to the present embodiment. As shown in FIG. 4, the electrode unit 10 generates a hydrogen-containing liquid in the liquid 100 by being placed in the liquid 100. As shown in FIG. 4, the electrode part 10 is put into the liquid 100 stored in the container 101 from the end part side opening part 10HB side. Therefore, the electrode part 10 is arrange | positioned in the liquid 100 in the state which located the edge part side opening part 10HB vertically downward. However, the position of the electrode unit 10 in the liquid 100 is not limited to this. For example, the electrode unit 10 is arranged so that the end-side opening 10HA and the end-side opening 10HB are positioned horizontally. May be.

  When a predetermined voltage (DC voltage) is applied from the power supply unit 20 between the anode unit 11 and the cathode unit 12 of the electrode unit 10, the hydrogen-containing liquid generation apparatus 1 in the present embodiment The reaction of formula (1) occurs.

2H ₂ O → O ₂ + 4H ⁺ + 4e ⁻ (1)

  Further, in the hydrogen-containing liquid generating apparatus 1 according to the present embodiment, when a predetermined voltage (DC voltage) is applied from the power source unit 20 between the anode unit 11 and the cathode unit 12 of the electrode unit 10, The reaction of the following formula (2) occurs.

4H ⁺ + 4e ⁻ → 2H ₂ (2)

  When a predetermined voltage (DC voltage) is applied from the power source unit 20 between the anode unit 11 and the cathode unit 12 of the electrode unit 10, the hydrogen-containing liquid generation apparatus 1 in the present embodiment is configured to have the anode unit 11 and the cathode unit. In the whole of 13, reaction of following formula (3) occurs.

2H ₂ O → O ₂ + 2H ₂ (3)

As described above, the hydrogen-containing liquid generating apparatus 1 according to the present embodiment is suppressed from the generation of acidic liquid, and is neutral, for example, about pH 7 to 7.5. Thus, the ionized hydrogen ions H ⁺ generated in the anode part 11 pass through the insulator 13 and gather on the cathode part 12 side, and bubbles of hydrogen gas (H ₂ ) are generated in the cathode part 12. These bubbles are minute bubbles having a diameter of nanometer order. Oxygen gas (O ₂ ) gathers as bubbles inside the cylindrical anode portion 11, moves along the inside of the anode portion 11, and is released from the end-side opening 10 HA to the outside of the anode portion 11. The

  Next, the shape of the electrode part 10 is demonstrated in detail. FIG. 5 is a side view showing the electrode unit according to the present embodiment. FIG. 5 shows a state in which a part of the cathode portion 12 and the insulator 13 of the electrode portion 10 is removed. FIG. 6 is a cross-sectional view of the electrode unit according to the present embodiment.

  In the present embodiment, the length LH in the longitudinal direction E of the cylindrical electrode portion 10 is preferably 50 mm or more and 90 mm or less. Moreover, it is preferable that the outer diameter LD of the electrode part 10 is 10 mm or more and 15 mm or less. When the length LH and the outer diameter LD of the electrode part 10 are in this range, the electrode part 10 can be easily put into the container 101 even when the container 101 is a container for beverages, for example.

  As shown in FIG. 5, the anode part 11 has a plurality of openings 11H on the side part, and the cathode part 12 has a plurality of openings 12H on the side part. The plurality of openings 11 </ b> H included in the anode part 11 penetrates the side part of the anode part 11 in the thickness direction of the anode part 11. The plurality of openings 12 </ b> H included in the cathode portion 12 penetrates the side portion of the cathode portion 12 in the thickness direction of the cathode portion 12. In this embodiment, the anode part 11 and the cathode part 12 are manufactured with a conductor, and in this embodiment, titanium (Ti) is plated with platinum (Pt). The plating may be, for example, platinum (Pt) -iridium (Ir) plating. In the present embodiment, the titanium is pure titanium. The anode portion 11 and the cathode portion 12 are not limited to those obtained by plating platinum on titanium, but are preferably materials that do not dissolve in the liquid 100 (for example, vanadium (V)). In the present embodiment, both the anode portion 11 and the cathode portion 12 are plated, but only the anode portion 11 may be plated and the cathode portion 12 may not be plated. By doing in this way, the manufacturing cost of the electrode part 10 can be reduced.

  As shown in FIG. 6, the insulator 13 interposed between the anode part 11, the outer side part (outer part) 11 So of the anode part 11, and the inner side part (inner part) 12 Si of the cathode part 12 is The outer part 11So of the anode part 11 and the inner part 12Si of the cathode part 12 are in contact with each other. As shown in FIG. 5, the insulator 13 has a plurality of openings 13H. The opening 13H penetrates the insulator 13 in the thickness direction. As the insulator 13, for example, a net knitted with fibers of an insulating material (for example, resin) can be used. The insulator 13 may have an ion exchange function. For example, the insulator 13 may be an ion exchange membrane (cation exchange membrane). In this case, the insulator 13 may not have the opening 13H.

  As described above, the insulator 13 may use an ion exchange membrane, but an electrically neutral material is used. By doing in this way, the manufacturing cost of an insulator can be reduced and processing becomes easy. The ion exchange membrane has pores that allow ions to pass through but not water molecules. When an ion exchange membrane is used for the insulator 13, the electrode unit 10 provided with the insulator 13 has a possibility that the voltage required for generating the hydrogen-containing liquid is increased and the power consumption is increased. . In the present embodiment, the insulator 13 is a net-like member that is electrically neutral. For this reason, hydrogen-containing water can be generated at a lower voltage compared to the ion exchange membrane, and power consumption can be suppressed.

  In the case where a net knitted with insulating fibers is used for the insulator 13, the thickness of the insulator 13 is preferably 0.1 mm or more and 1 mm or less. In the present embodiment, the insulator 13 is in contact with the outer portion 11So of the anode portion 11 and the inner portion 12Si of the cathode portion 12. Accordingly, the distance (interelectrode gap) between the outer portion 11So of the anode portion 11 and the inner portion 12Si of the cathode portion 12 is determined by the thickness of the insulator 13. Since the gap between the electrodes is not less than 0.1 mm and not more than 1 mm, even when the potential difference of the voltage applied to the anode part 11 and the cathode part 12 is relatively small when the electrode part 10 generates the hydrogen-containing liquid, the electrode The unit 10 can generate a sufficient amount of hydrogen. If the gap between the electrodes is in the above-described range, even if the voltage applied to the electrode unit 10 is relatively low, the electrode unit 10 is a hydrogen in which a sufficient amount of hydrogen is dissolved in the liquid 100 to dissolve a large amount of hydrogen. The containing liquid 100H can be produced. Moreover, if the amount of hydrogen dissolved in the hydrogen-containing liquid 100H is the same, the electrode unit 10 can suppress power consumption.

  In the present embodiment, the electrode unit 10 is directly placed in the container 101 or the like to generate the hydrogen-containing liquid 100H. And after producing | generating hydrogen-containing liquid 100H, the electrode part 10 is taken out from the container 101 grade | etc.,. Thus, since the electrode part 10 is moved suitably, it is easy to receive the influence of a vibration and an impact. In the electrode part 10, when the insulator 13 is interposed between the anode part 11 and the cathode part 12 and brought into contact with both, the movement of the anode part 11 and the cathode part 12 is restricted. As a result, the electrode part 10 has improved resistance to vibration and impact.

  Further, when the insulator 13 is interposed between and contacted with the anode portion 11 and the cathode portion 12, the insulator 13 makes the interval between the anode portion 11 and the cathode portion 12 constant throughout the electrode portion 10. It becomes easy. As a result, the electrode portion 10 suppresses variations in electrical resistance between the anode portion 11 and the cathode portion 12 and suppresses variations in current density, so that hydrogen bubbles can be generated uniformly from the whole. it can. It is preferable to make the gap between the electrodes equal to the thickness of the insulator 13 because the insulator 13 can be easily brought into contact with both the anode portion 11 and the cathode portion 12.

  In the present embodiment, the anode power supply member 14 and the cathode power supply member 15 are members obtained by plating platinum on titanium, similarly to the anode portion 11 and the cathode portion 12. The anode power supply member 14 and the cathode power supply member 15 are not limited to titanium plated with platinum, like the anode portion 11 and the cathode portion 12, but are materials that do not dissolve in the liquid 100. Is preferred. The anode power supply member 14 and the cathode power supply member 15 are joined to the anode portion 11 and the cathode portion 12, respectively, by spot welding, for example. However, the anode power supply member 14 and the cathode power supply member 15 are not limited to welding as long as they are electrically connected to the anode portion 11 and the cathode portion 12, respectively, and any joining means may be used.

  The plating applied to the anode power supply member 14 and the cathode power supply member 15 may be, for example, platinum (Pt) -iridium (Ir) plating. In the present embodiment, the cathode portion 12 may not be plated. In this case, the cathode power supply member 15 may not be plated.

  Next, the openings 11H, 12H, and 13H included in the anode portion 11, the cathode portion 12, and the insulator 13 will be described. FIG. 7 is an enlarged view showing a part of the anode and the cathode. FIG. 8 is an enlarged view of the openings of the anode and the cathode. 9 is a cross-sectional view taken along the line BB in FIG. FIG. 10 is an enlarged view showing a part of the insulator. The anode portion 11 and the cathode portion 12 are net-like members in which a plurality of linear portions (linear portions) 16 intersect. The portions surrounded by the plurality of linear portions 16 become the openings 11H and 12H of the anode portion 11 and the cathode portion 12. In the present embodiment, the openings 11H and 12H included in the anode part 11 and the cathode part 12 have a rhombus shape. In the openings 11H and 12H, one diagonal line (first diagonal line) TLl is longer than the other diagonal line (second diagonal line) TLs. In the openings 11H and 12H, the angles at the top portions Pa and Pb on the first diagonal line TLl are smaller than the angles at the top portions Pc and Pd on the second diagonal line TLs.

  Since the anode part 11 and the cathode part 12 have a plurality of openings 11H and 12H, the lines of electric force can be turned inward and outward through the openings 11H and 12H. For this reason, since both the anode part 11 and the cathode part 12 can be utilized for electrolysis, hydrogen can be generated efficiently. Further, since the cathode portion 12 can reduce the wetting angle of hydrogen bubbles generated by the opening 12H surrounded by the linear portion 16, the hydrogen bubbles can be released in a small state. That is, the adsorptive force generated between the generated hydrogen and the surface of the cathode part 12 becomes close to point contact, and the surface tension is suppressed. As a result, the cathode part 12 reduces hydrogen bubbles. It is possible to produce hydrogen-containing water in which many hydrogen bubbles are dissolved by being separated in a state.

  In the present embodiment, the linear portions 16 of the anode portion 11 and the cathode portion 12 have a rectangular cross section (square in the example of FIG. 9) as shown in FIG. The cathode portion 12 can further reduce the wetting angle of the hydrogen bubbles and suppress the surface tension by the corner portion 16T of the linear portion 16, so that the hydrogen bubbles can be released in a smaller state. . For this reason, the cathode portion 12 can generate hydrogen water in which smaller hydrogen bubbles are dissolved. Moreover, since the cathode part 12 has the linear part 16 whose cross section is a rectangle, the surface area which can be utilized for generation | occurrence | production of hydrogen can be enlarged. By these actions, the cathode part 12 improves the efficiency of dissolving hydrogen in the raw water.

  In the present embodiment, as shown in FIG. 8, in the openings 11H and 12H, the first diagonal line TLl is directed in the direction in which the anode portion 11 and the cathode portion 12 extend, that is, the longitudinal direction E. The second diagonal line TLs is directed in the circumferential direction C of the cylindrical anode portion 11 and the cathode portion 12. The anode part 11 and the cathode part 12 have end side openings 10HA and 10HB on both sides in the longitudinal direction E, as shown in FIG. The oxygen bubbles generated inside the anode portion 11 are discharged to the outside of the electrode portion 10 through the end portion side opening 10HA as shown in FIG. At this time, since the major axis direction of the opening 11H of the anode portion 11 is aligned in the direction in which the oxygen bubbles move, the oxygen bubbles easily move to the end-side opening 10HA. As a result, the electrode unit 10 can efficiently release oxygen bubbles to the outside. In addition, the opening 11H of the anode portion 11 has an acute angle between the top portions Pa and Pb on the first diagonal line TLl, so that the contact area between the oxygen bubbles and the linear portion 16 can be reduced. As a result, the oxygen bubbles are easily separated from the linear portion 16, so that the electrode unit 10 can efficiently release the oxygen bubbles to the outside. Moreover, since the linear part 16 has the corner | angular part 16T, the anode part 11 can further reduce the wetting angle of the bubble of oxygen by this corner | angular part 16T, and can suppress surface tension. As a result, the anode portion 11 can quickly remove oxygen bubbles from the linear portion 16 and move them to the end side openings 10HA and 10HB. For this reason, the electrode part 10 can discharge | release the bubble of oxygen efficiently outside. Further, in the process of moving the oxygen bubbles along the inside of the anode portion 11, the oxygen bubbles newly generated on the anode portion 11 side are taken in and the oxygen bubbles grow. For this reason, it is possible to reduce the area where the oxygen bubbles and the liquid 100 are in contact with each other, thereby suppressing the dissolution of oxygen in the liquid 100.

  As shown in FIG. 10, the insulator 13 is a net-like member in which a plurality of linear members 17 intersect and a portion surrounded by the linear members 17 is an opening 13H. The opening 13H has a rectangular shape (in this embodiment, a square shape). The length of one side of the opening 13H is La, and the length of the side adjacent to this side is Lb. In the present embodiment, since the opening 13H has a square shape, La = Lb. The side with the length La is parallel to the longitudinal direction E of the anode part 11 and the cathode part 12, and the side with the length Lb is parallel to the circumferential direction C of the cylindrical anode part 11 and cathode part 12. .

In the present embodiment, the opening 11H of the anode part 11 and the opening 12H of the cathode part 12 are larger than the opening 13H of the insulator 13. The areas of the openings 11H and 12H are L1 × Ls / 2 where the length of the first diagonal line TLl is L1 and the length of the second diagonal line TLs is Ls. The area (opening area) of the opening 13H is La × Lb. Therefore, L1 × Ls / 2> La × Lb. In the present embodiment, for example, the length Ll of the first diagonal line TLl is 6 mm and the length Ls of the second diagonal line TLs is 3 mm, so the areas of the openings 11H and 12H are 9 mm ² . The opening 13H is, for example, La = Lb = 1.06 mm. That is, the insulator 13 has 24 openings 13H arranged per inch. The area (opening area) of the opening 13H is 1.12 mm ² . Thus, in this embodiment, the area of the openings 11H and 12H of the anode part 11 and the cathode part 12 is about eight times the area of the opening 13H of the insulator 13.

  When the opening 13H of the insulator 13 is larger than the openings 11H and 12H of the anode part 11 and the cathode part 12, there is a high possibility that the anode part 11 and the cathode part 12 come into contact through the opening 13H of the insulator 13. In the electrode part 10, the anode part 11 and the cathode part 12 come into contact with each other through the opening 13 </ b> H of the insulator 13 by making the opening 13 </ b> H of the insulator 13 smaller than the openings 11 </ b> H and 12 </ b> H of the anode part 11 and the cathode part 12. You can avoid that. Thus, even if the distance between the anode part 11 and the cathode part 12 is reduced, the electrode part 10 can avoid a short circuit between the anode part 11 and the cathode part 12 and ensure insulation between them.

  In the present embodiment, the insulator 13 is a net-like member in which a plurality of linear members 17 are crossed. When such a net-like member is used, the insulator 13 is allowed to be deformed to some extent in the thickness direction. Therefore, when the electrode portion 10 receives vibration or impact, the insulator 13 can absorb it. .

  In the electrode portion 10, since the opening 13 </ b> H of the insulator 13 is smaller than the opening 11 </ b> H of the anode portion 11 and the opening 12 </ b> H of the cathode portion 12, oxygen bubbles generated on the anode portion 11 side are removed by the linear member 17 of the insulator 13. It can be trapped into large bubbles. Since the oxygen bubbles are increased, the dissolution of oxygen in the liquid 100 is suppressed, so that the electrode unit 10 can generate a hydrogen-containing liquid having a high dissolved rate of hydrogen bubbles. Further, since the buoyancy increases as the oxygen bubbles increase, the oxygen bubbles easily move inside the anode portion 11 and easily pass through the opening 13H. It becomes easy to discharge from the inside.

  Next, stirring of the liquid 100 by the stirring unit 33 will be described. FIG. 11 is a schematic diagram illustrating a state in which the stirring unit according to the present embodiment is stirring the liquid. As shown in FIG. 11, the hydrogen-containing liquid generation apparatus 1 is attached to a container 102 in which a liquid 100 is stored. The container 102 is a container having an opening 103 having an outer diameter reduced at one end of a cylindrical member and having a bottom 104 at the other end. Since the container 102 is cylindrical, it has a central axis AX3. In the present embodiment, the container 102 is a plastic bottle in which a beverage is stored. The container 102 does not have to be a plastic bottle, and any shape can be used as long as it is a cylindrical container having an opening at one end and a bottom at the other end.

  As shown in FIG. 11, the attachment portion 2 is attached to the container 102 by covering the inner peripheral portion of the fixing portion 4 on the outer peripheral portion of the opening 103 of the container 102. The electrode unit 10 and the stirring unit 33 extend from the inside of the fixed unit 4 in a direction away from the mounting unit 2. Therefore, the electrode part 10 and the stirring part 33 are accommodated in the container 102 and put in the liquid 100 by covering the opening part 103 of the container 102 with the fixing part 4 of the attachment part 2. At this time, the short-diameter side end portion 37c of the stirring portion 33 and the bottom portion 104 of the container 102 face each other. Further, the rotation axis AX1 of the shaft portion 32, the center axis AX2 of the electrode portion 10, and the center axis AX3 of the container 102 are parallel to each other. More specifically, the rotation axis AX1 of the shaft portion 32, the center axis AX2 of the electrode portion 10, and the center axis AX3 of the container 102 coincide with each other. The container 102 is a plastic bottle, and an external thread is provided on the outer periphery of the opening 103. The outer periphery of the fixing portion 4 of the attachment portion 2 may have a female screw portion that can be attached to the outer thread portion of the opening portion 103 and fastened to each other.

  After the attachment part 2 is attached to the container 102, the control part 21 causes the power supply part 20 to apply a DC voltage to the electrode part 10. The electrode unit 10 electrolyzes the liquid 100 when a DC voltage is applied to generate bubble-like hydrogen at the cathode unit 12. Further, bubble-like oxygen is generated in the anode portion 11.

  The control unit 21 causes the power supply unit 20 to apply a DC voltage to the drive unit 31 at the same time as the power supply unit 20 applies a DC current to the electrode unit 10. The drive unit 31 rotates the stirring unit 33 when a DC voltage is applied. The application of the DC voltage to the drive unit 31 may not be performed simultaneously with the application of the DC current to the electrode unit 10, and may be performed either before or after the application of the DC current to the electrode unit 10.

  As shown in FIG. 11, the stirring unit 33 is rotated to generate a spiral water flow S <b> 1 toward the bottom 104 of the container 102 along the longitudinal direction E of the electrode unit 10. The water flow S1 is reflected by the bottom 104, and generates a water flow S2 as a reflected wave of the water flow S1. The water flow S <b> 2 is a spiral water flow (vortex) toward the opening 103. The water flow S2 generates a centrifugal force in the container 102 and stirs the liquid 100.

  The bubble-like hydrogen generated in the cathode portion 12 is separated from the cathode portion 12 to the outside by the centrifugal force generated by the water flow S2 while the bubbles are in a small state. Further, the bubble-like hydrogen detached from the cathode portion 12 is widely dispersed in the liquid 100 by the centrifugal force generated by the water flow S2. Accordingly, the bubble-like hydrogen is easily dissolved in the liquid 100.

  On the other hand, a spiral water flow S <b> 3 toward the opening 103 is generated in the interior 52 of the anode portion 11. The interior 52 of the anode part 11 is located on the rotation center side of the water flow S2. Further, the inside 52 of the anode part 11 is separated from the outside of the anode part 11 (outside of the cathode part 12) by the anode part 11, the insulator 13 and the cathode part 12. Therefore, the water flow S3 generates a centripetal force toward the center of rotation in the interior 52 of the anode portion 11, unlike the water flow S2 generated in the container 102 and outside the anode portion 11.

  The bubble-like oxygen generated in the anode part 11 is separated from the anode part 11 inward by the centripetal force generated by the water flow S3 while the bubbles are in a small state. The detached bubble-like oxygen gathers together due to the centripetal force of the water flow S3. The collected bubble-like oxygen travels toward the opening 103 by the water flow S3 toward the opening 103. Therefore, bubble-like oxygen is difficult to dissolve in the liquid 100 and is easily released into the atmosphere from the opening 103.

  As described above, in the hydrogen-containing liquid generating apparatus 1 according to this embodiment, the electrode unit 10 electrolyzes the liquid 100 and the stirring unit 33 is rotated to stir the liquid 100. Further, the stirring unit 33 is rotated about a rotation axis AX1 parallel to the axis along the longitudinal direction E of the electrode unit 10. The hydrogen-containing liquid generating apparatus 1 stirs the liquid 100 by the agitating unit 33 to separate the bubble-like hydrogen generated by the electrolysis of the liquid 100 from the cathode unit 12 while the bubbles are small, and Disperse widely in the liquid 100. Thus, since the hydrogen-containing liquid production | generation apparatus 1 can disperse | distribute hydrogen with a small bubble widely in the liquid 100, it becomes easy for hydrogen to dissolve in the liquid 100, and improves the hydrogen dissolved amount of the hydrogen-containing liquid 100H. Can be made.

  Further, the rotation axis AX1 of the stirring unit 33 and the axis along the longitudinal direction E of the electrode unit 10 are parallel to each other. Therefore, the water flow S <b> 1 generated by the stirring unit 33 is spiral and is generated in a direction along the longitudinal direction E of the electrode unit 10. Accordingly, a spiral water flow S <b> 2 is generated around the electrode portion 10 along the longitudinal direction E. Since the spiral water flow S2 is generated along the longitudinal direction E of the electrode portion 10, hydrogen generated in the cathode portion 12 can be preferably separated from the cathode portion 12. Therefore, the hydrogen-containing liquid generating apparatus 1 can improve the amount of hydrogen dissolved in the hydrogen-containing liquid 100H.

  Moreover, the container 102 in which the liquid 100 is stored is a plastic bottle, and the opening part of the opening part 103 is small. Therefore, for example, it is difficult to stir the liquid 100 by putting a mudler or the like in the container 102 in which the electrode unit 10 is placed and stirring the mudler. However, in this embodiment, the stirring unit 33 is rotated by the drive unit 31. Therefore, the hydrogen-containing liquid generating apparatus 1 according to this embodiment can stir the liquid 100 simply by putting the stirring unit 33 in the container 102 and driving the driving unit 31. In other words, the hydrogen-containing liquid production | generation apparatus 1 can stir the liquid 100, without performing the operation | work of stirring, and can improve the hydrogen dissolved amount of the hydrogen-containing liquid 100H.

  Moreover, in this embodiment, the stirring part 33 is located in the edge part side opening part 10HB which is an edge part of the longitudinal direction E of the electrode part 10. As shown in FIG. Therefore, the stirring unit 33 can make the rotation axis of the water flow S1 coincide with the central axis AX2 of the electrode unit 10. Therefore, the stirring unit 33 can generate a water flow S2 around the electrode unit 10 with the electrode unit 10 as a rotation center. Since this water flow S2 is a spiral water flow with the electrode portion 10 as the center of rotation, a centrifugal force is suitably generated in the hydrogen generated in the cathode portion 12. Accordingly, the stirring unit 33 can more suitably separate the hydrogen generated in the cathode unit 12 from the cathode unit 12 and widely disperse the hydrogen in the liquid 100. Therefore, the hydrogen-containing liquid production | generation apparatus 1 can improve the hydrogen dissolved amount of the hydrogen-containing liquid 100H more suitably.

  Furthermore, in the present embodiment, a cylindrical anode portion 11 is provided inside the cylindrical cathode portion 12. A shaft portion 32 is provided in the interior 52 of the anode portion 11. The shaft portion 32 has one end portion 32a rotationally driven by the drive portion 31, and the other end portion 32b to which the stirring portion 33 is attached. The agitating part 33 is rotated by a shaft part 32 extending to the inside 52 of the anode part 11. Therefore, the hydrogen-containing liquid production | generation apparatus 1 in this embodiment can simplify the shape which attaches the stirring part 33. FIG. In the present embodiment, since the anode portion 11 is provided inside the cathode portion 12, only the cathode portion 12 is exposed at the outermost periphery, and the anode portion 11 is not exposed to the outside. Therefore, for example, even when the user touches the outer periphery of the electrode part 10, the user touches only the cathode part 12 and does not touch the anode part 11. Therefore, the hydrogen-containing liquid production | generation apparatus 1 which concerns on this embodiment suppresses that the electrode part 10 short-circuits, for example, when a user touches the electrode part 10 during operation | movement, and can raise the safety | security. it can.

  Further, in the present embodiment, the electrode unit 10 includes an insulator 13. The insulator 13 is provided between the outer peripheral part of the anode part 11 and the inner peripheral part of the cathode part 12 and is in contact with the anode part 11 and the cathode part 12. The anode portion 11 and the cathode portion 12 have a plurality of openings 11H and 12H on the side portions. In the electrode part 10, since the anode part 11 and the cathode part 12 have openings 11H and 12H, hydrogen can be generated efficiently. Therefore, in the hydrogen-containing liquid generating apparatus 1 according to the present embodiment, the electrode unit 10 efficiently generates hydrogen and the stirring unit 33 improves the hydrogen dissolved amount, so that the hydrogen dissolved amount of the hydrogen-containing liquid 100H is increased. It can improve more suitably.

  Furthermore, in this embodiment, the stirring part 33 has the long diameter side edge part 37b in the side (electrode part 10 side) to which the shaft part 32 was attached. The stirring portion 33 has a short-diameter side end portion 37c at an end portion in a direction opposite to the electrode portion 10. Therefore, the stirring unit 33 can more suitably generate the water flow S <b> 1 toward the bottom 104 (the direction opposite to the electrode unit 10) of the container 102. Therefore, the hydrogen-containing liquid production | generation apparatus 1 can improve the hydrogen dissolved amount of the hydrogen-containing liquid 100H more suitably.

  Furthermore, in this embodiment, the hydrogen-containing liquid production | generation apparatus 1 has the attaching part 2 attached to the edge part side opening part 10HA of the electrode part 10. As shown in FIG. The attachment portion 2 is attached to the opening 103 of the container 102. The attachment portion 2 is attached to the opening portion 103 of the container 102, thereby arranging the electrode portion 10 and the stirring portion 33 in the container 102. The attachment portion 2 is attached to the opening 103 of the container 102 so that the stirring portion 33 and the bottom portion 104 of the container 102 face each other. In the hydrogen-containing liquid generating apparatus 1, the agitation part 33 and the bottom part 104 of the container 102 can be preferably opposed to each other by the attachment part 2. Since the stirring unit 33 faces the bottom 104 of the container 102, the water flow S1 toward the bottom 104 of the container 102 can be more suitably generated. Therefore, the hydrogen-containing liquid production | generation apparatus 1 can improve the hydrogen dissolved amount of the hydrogen-containing liquid 100H more suitably.

  In the present embodiment, the attachment portion 2 is a columnar member having the open fixed portion 4 and houses a part of the electrode portion 10 and the like therein. However, the attachment part 2 is attached to the opening 103 of the container 102 so that the electrode part 10 and the stirring part 33 are arranged in the container 102 so that the stirring part 33 and the bottom part 104 of the container 102 face each other. If present, the shape is arbitrary. Moreover, the attachment part 2 does not need to accommodate some electrode parts 10 etc. in an inside.

(Modification 1)
Next, Modification 1 of the hydrogen-containing liquid generating apparatus 1 according to this embodiment will be described. The hydrogen-containing liquid production | generation apparatus 1A which concerns on the modification 1 differs in the electrode part and the stirring part from the hydrogen-containing liquid production | generation apparatus 1. FIG. Since the other points of the hydrogen-containing liquid generating apparatus 1A according to the modification 1 are the same as those of the hydrogen-containing liquid generating apparatus 1, description thereof is omitted.

One surface 11AS1 of the anode portion 11A and one surface 12AS1 of the cathode portion 12A are separated from each other by a predetermined distance LA and are opposed to each other so as to extend along the longitudinal direction EA. Accordingly, the electrode portion 10A extends along the longitudinal direction EA. Further, the cover portion 19A is an insulating member that covers the anode portion 11A and the cathode portion 12A in a state where the surfaces thereof are opposed to each other. More specifically, the cover portion 19A covers the side surfaces of the anode portion 11A and the cathode portion 12A. On the other hand, the cover portion 19A does not cover the other surface 11AS2 of the anode portion 11A and the other surface 12AS2 of the cathode portion 12A. That is, the other surface 11AS2 of the anode portion 11A and the other surface 12AS2 of the cathode portion 12A are exposed to the outside.

  The power supply unit 20A applies a DC potential to the electrode unit 10A and the drive unit 31A. The drive unit 31A converts electrical energy generated by the DC voltage of the power supply unit 20A into rotational motion.

  The bearing portion 35A is a cylindrical slide bearing in which one end portion 35Aa is fixed to the storage portion 2A. The bearing portion 35A is not rotationally driven because it is not connected to the drive portion 31A. Further, the shaft portion 32A is penetrated through the bearing portion 35A. The bearing portion 35A acts as a bearing for the shaft portion 32A and does not rotate itself. The bearing portion 35A may also be used as a gripping portion that is gripped by the user.

  The electrode part 10A according to the first modification is rotated by the drive part 31A via the shaft part 32A and the cover part 19A. That is, the electrode unit 10A according to the modification 1 also functions as a stirring unit. 10 A of electrode parts which concern on the modification 1 agitate the liquid 100 by electrolyzing the liquid 100 by applying a DC voltage to the power supply part 20A, and being rotationally driven by the drive part 31A.

  The electrode unit 10A according to the modification 1 agitates the liquid 100 by electrolyzing the liquid 100 and being rotationally driven by the driving unit 31A. Further, in the electrode portion 10A, an axis AX2A along the longitudinal direction EA of the electrode portion 10A serves as a rotation axis of the electrode portion 10A. That is, the axis AX2A along the longitudinal direction EA of the electrode portion 10A matches the rotation axis of the electrode portion 10A. Therefore, the hydrogen-containing liquid production | generation apparatus 1A which concerns on the modification 1 can improve the hydrogen dissolved amount of the hydrogen-containing liquid 100H similarly to the hydrogen-containing liquid production | generation apparatus 1. FIG.

(Modification 2)
Next, Modification 2 of the hydrogen-containing liquid generating apparatus 1 according to this embodiment will be described. The hydrogen-containing liquid generating apparatus 1B according to Modification 2 is different from the hydrogen-containing liquid generating apparatus 1 in the electrode unit and the stirring unit. Since the other points of the hydrogen-containing liquid generating apparatus 1B according to the modification 2 are the same as those of the hydrogen-containing liquid generating apparatus 1, description thereof is omitted.

  FIG. 14 is a schematic diagram illustrating an electrode unit and a stirring unit of the hydrogen-containing liquid generating device according to the second modification. FIG. 15 is a schematic diagram illustrating an electrode unit and a stirring unit of a hydrogen-containing liquid generation device according to Modification 2.

Part 33B. The storage unit 2B stores therein a part of the electrode unit 10B, the power supply unit 20B, the drive unit 31B, the coupling unit 32B, and a part of the stirring unit 33B.

  As shown in FIG. 15, the electrode portion 10B includes an anode portion 11B, a cathode portion 12B, and a fixing portion 41B. The anode portion 11B is an axial conductor whose longitudinal direction EB as one direction is longer than the other directions. The cathode portion 12B is an axial conductor whose longitudinal direction EB as one direction is longer than the other directions. The fixing portion 41B is attached to one end of the anode portion 11B and the cathode portion 12B. The fixing part 41B separates the anode part 11B and the cathode part 12B from each other, and maintains the distance between the central axes of the anode part 11B and the cathode part 12B at a predetermined distance LB. Are fixed to face each other so as to extend along the longitudinal direction EA. Accordingly, the electrode portion 10B extends along the longitudinal direction EB.

  The fixing portion 41B is an insulating member that is stored in the storage portion 2B and is fixed to the drive portion 31B in the storage portion 2B. However, the fixed portion 41B is not rotationally driven by the drive portion 31B.

  The power supply unit 20B applies a DC potential to the electrode unit 10B and the drive unit 31B. The drive unit 31B converts electrical energy generated by the DC voltage of the power supply unit 20B into rotational motion.

  The coupling portion 32B has a shape in which the outer diameter of one end portion 32aB of the cylindrical member is increased. The coupling part 32B is connected to the drive part 31B at the other end part 32bB. The coupling part 32B is rotationally driven by the drive part 31B. In addition, a fixing portion 41B of the electrode portion 10B is disposed inside the coupling portion 32B. The coupling part 32B and the fixing part 41B are not in contact with each other. Therefore, even if the coupling part 32B is rotationally driven, the electrode part 10B does not rotate.

  Stirrer 33B has a plurality of ring-shaped parts 53B and a plurality of axial parts 55B. The ring-shaped part 53B is a ring-shaped member. The plurality of ring-shaped portions 53B are arranged coaxially with each other. The shaft portion 55B is a shaft-like member attached to the outer peripheral portion of the plurality of ring-shaped portions 53B, and connects the plurality of ring-shaped portions 53B so as to be arranged coaxially with each other. That is, the stirring portion 33B is a long-axis member in which a plurality of ring-shaped members 53B, which are a plurality of ring-shaped members, are arranged on the same axis, and the ring-shaped portions 53B are connected to each other by a shaft portion 55B that is a shaft-shaped member. .

  As for the stirring part 33B, the ring-shaped part 53B by the side of one edge part 57B is attached to the coupling part 32B. More specifically, the inner periphery of the ring-shaped portion 53B on the one end portion 57B side and the outer periphery of the one end portion 32aB of the coupling portion 32B are fixed to each other. And the stirring part 33B has the anode part 11B and the cathode part 12B arrange | positioned inside the some ring-shaped part 53B. In other words, the stirring part 33B has the anode part 11B and the cathode part 12B penetrating therethrough. Moreover, since the stirring part 33B is connected to the coupling part 32B, it is rotated by the drive part 31B via the coupling part 32B.

  The electrode unit 10B according to Modification 2 electrolyzes the liquid 100 by applying a DC voltage to the power supply unit 20B. Further, the agitating unit 33B agitates the liquid 100 by being driven to rotate by the driving unit 31B. Moreover, the electrode part 10B is provided inside the stirring part 33B. And the axis | shaft which is an axis | shaft along the longitudinal direction EB of the electrode part 10B is parallel to the rotating shaft AX1B of the stirring part 33B. Therefore, similarly to the hydrogen-containing liquid generating apparatus 1, the hydrogen-containing liquid generating apparatus 1B according to the modified example 2 can improve the amount of hydrogen dissolved in the hydrogen-containing liquid 100H.

  As shown in the modified examples 1 and 2, the hydrogen-containing liquid generating apparatus 1 includes the anode part 11 and the cathode part 12 in which one direction as a longitudinal direction is longer than the other direction.
