Conventionally, devices described in Patent Documents 1 and 2 are known as devices using electrolyzed water.

Patent Document 1 discloses a reduced water generator in which a pair of plate electrodes are attached to the inner bottom surface of a dish-shaped container, and a DC power source for supplying power to these plate electrodes is disposed in a space provided below the container. It is disclosed. The container lid is provided with a flow hole at a position corresponding to the position directly above each plate electrode, and the hydrogen generated in one plate electrode flows out from one flow hole and the other plate electrode.

In recent years, attention has been focused on “hydrogen water” containing a lot of hydrogen, and an apparatus for electrolyzing water to generate hydrogen water has been released. Such an apparatus for generating hydrogen water is considered to be realized by a configuration similar to that of Patent Document 2 described above, but there is room for improvement in terms of the amount of dissolved hydrogen. That is, even if the hydrogen concentration in the water immediately above the apparatus is saturated, it is difficult to maintain a sufficient hydrogen concentration in the water in the region away from the apparatus.

This invention was made in view of the said subject, and aims at improving the hydrogen concentration of the water implement | achieved by the hydrogen water production | generation apparatus used by being immersed in water compared with the past.

One aspect of the present invention includes a case that has a water passage that can be immersed in water and that communicates a water inlet and an outlet, a pump that generates a water flow in the water passage, and a water passage that is disposed in the water passage. An electrolysis unit provided; and a power supply unit that feeds power to the pump unit and the electrolysis unit, wherein the electrolysis unit includes a plurality of porous electrode plates arranged at regular intervals, and the pump The unit is a hydrogen water generating device that generates a water flow toward the plate surface of the porous electrode plate.

The hydrogen water generating apparatus configured in this manner is immersed in water, a water flow is generated in the water passage between the inlet and the outlet by the pump unit, and the water passage is circulated by the electrolytic unit disposed in the water passage. Electrolyze water to be used. At this time, the pump unit generates a water flow toward the plate surface of the porous electrode plate disposed at a constant interval that constitutes the electrolysis unit. That is, by applying the pressure of the water flow to the plate surface of the porous electrode plate, there is an effect of incorporating hydrogen and oxygen bubbles generated by electrolysis on the surface of the porous electrode plate into the water flow so as to push away at the moment of electrolysis. It can be expected that hydrogen bubbles contained in the water flowing out from the outlet of the generating device will be microbubbled or dissolved in molecular level hydrogen, nanobubbles or microbubbles.

Also, one of the selective aspects of the present invention is a hydrogen water generator characterized by comprising a control unit that reverses the polarity of the porous electrode plate every predetermined time during electrolysis.

Mineral components such as calcium dissolved in the water to be electrolyzed, particularly metal ions present in the form of a cation in water, will be deposited on the cathode surface as a scale. The porous electrode plate that functioned as an anode and the porous electrode plate that functioned as an anode switched to a cathode every predetermined time, so that the deposition of the scale was approximately equal for each porous electrode plate, and Since the deposited scale is redissolved in water on the switched porous electrode plate and the scale is removed, it is possible to suppress a reduction in electrolytic efficiency due to scale adhesion.

Also, one of the selective aspects of the present invention is the hydrogen water generating apparatus, wherein the control unit performs the polarity reversal while the pump unit is in operation.

By adopting such a configuration, it is possible to avoid a temporary short circuit state between the porous electrode plates at the time of polarity switching due to the electrolyzed water existing between the porous electrode plates having capacity. It is possible to maintain an electric circuit that performs power supply or switching to the plate.

Also, one of the selective aspects of the present invention is a hydrogen water generating apparatus comprising a control unit that controls the pump unit during electrolysis to vary the flow rate of the water flow.

With such a configuration, the bubble diameter of the hydrogen bubbles peeled off from the surface of the porous electrode plate can be changed.

Also, one of the selective aspects of the present invention is that the pump unit is repeatedly operated during electrolysis in a relatively long operation state that generates a water flow and a relatively short stop state that does not generate a water flow. The hydrogen water generating apparatus is characterized by comprising means for releasing difficult-to-separate bubbles adhering to the porous electrode plate in the operating state of the pump unit by a control unit that performs switching control.

By adopting such a configuration, although the bubble diameter that should have been peeled off by a water flow is originally reached, the difficult-to-peel bubbles that continue to adhere to the porous electrode plate are peeled off, and the surface of the porous electrode plate is It is possible to suppress a decrease in electrolytic efficiency derived from being covered with bubbles.

Also, one of the selective aspects of the present invention is a hydrogen water generating apparatus in which a sharp charge concentration portion is formed at the periphery of the bubble circulation hole formed in the porous electrode plate.

By adopting such a configuration, it is possible to generate many hydrogen bubbles that can be visually recognized by the user while having relatively high solubility in water.

One of the selective aspects of the present invention is that the porous electrode plate has a polygonal cross-section in which a partition portion partitioning between the bubble circulation holes of the porous electrode plate has a corner portion that becomes a tip toward the water flow. There is a hydrogen water generating apparatus characterized by that.

In the hydrogen water generating apparatus configured as described above, the partition portion has an inclined surface for receiving the water flow generated by the pump portion toward the bubble flow holes on both sides between the bubble flow holes of the porous electrode plate. The defoaming property on the surface of the plate is improved. In addition, since the surface between the bubble circulation holes of the porous electrode plate is configured as another discontinuous surface across the corner, the bubbles generated on one surface merge with the bubbles generated on the other surface. It is difficult to expect the bubbles released from the porous electrode plate to become finer, and to be dissolved in hydrogen at molecular level hydrogen, nanobubbles or microbubbles. In addition, since the porous electrode plate has corners directed to the water flow between the bubble circulation holes, the water flow that sequentially flows through the bubble circulation holes of the plurality of porous electrode plates becomes smooth, and the porous electrode plate farthest from the pump portion The water force can be maintained until the bubble circulation hole is circulated. In addition, since the corner portion has a small surface tension, the bubble releasing property of bubbles generated at the corner portion between the bubble circulation holes of the porous electrode plate directly hit by the water flow is improved.

One of the selective aspects of the present invention is a hydrogen water generating device in which the bubble circulation holes of the plurality of porous electrode plates are provided in a substantially staggered positional relationship between adjacent porous electrode plates.

In the hydrogen water generating apparatus configured as described above, since the positions of the bubble circulation holes formed in the plurality of porous electrode plates are alternately formed, the water flow through the bubble circulation holes reaches every corner between the porous electrode plates. It distribute | circulates along a porous electrode plate, While improving the foam separation property in the whole surface of a porous electrode plate, the substitution efficiency of water can be improved between several porous electrode plates.

Moreover, the following point is mentioned as a selective aspect of this invention.
(1) It is configured to pressurize the water flow discharged from the pump through the gaps between the plurality of porous electrode plates to dissolve hydrogen generated in the porous electrode plate in the water flow under pressure.
(2) An insulating electrode cover is arranged on the upper part of the porous electrode plate in the electrolysis part, and the cell cover has a bubble flow hole at a position substantially alternate with the bubble flow hole formed in the opposed porous electrode plate. To provide.
(3) A light emitting means for emitting light in a direction intersecting with the water flow flowing out from the outlet is provided.

The hydrogen water generation apparatus described above includes various modes such as being implemented in a state of being incorporated in another device or implemented together with another method. Moreover, this technique is realizable also as a hydrogen water generation system provided with the said hydrogen water production | generation apparatus.

According to the present invention, it is possible to improve the hydrogen concentration of water realized by a hydrogen water generator used by being immersed in water as compared with the conventional case.

According to the hydrogen water generating apparatus according to claim 2, since it has a shape that is inclined with respect to the water flow generated by the pump portion between the bubble circulation holes of the porous electrode plate, the defoaming property on the surface of the porous electrode plate is improved. To do. In addition, since the surface between the bubble circulation holes of the porous electrode plate is configured as another discontinuous surface across the corner, the bubbles generated on one surface merge with the bubbles generated on the other surface. It is difficult to expect the bubbles released from the porous electrode plate to become finer, and to be dissolved in hydrogen at molecular level hydrogen, nanobubbles or microbubbles. In addition, since the porous electrode plate has corners directed to the water flow between the bubble circulation holes, the water flow that sequentially flows through the bubble circulation holes of the plurality of porous electrode plates becomes smooth, and the porous electrode plate farthest from the pump portion The water force can be maintained until the bubble circulation hole is circulated. In addition, since the corner portion has a small surface tension, the bubble releasing property of bubbles generated at the corner portion between the bubble circulation holes of the porous electrode plate directly hit by the water flow is improved.

According to the hydrogen water generating apparatus according to claim 3, since the positions of the bubble circulation holes formed in the plurality of porous electrode plates are alternately formed, the water flow passing through the bubble circulation holes is every corner between the porous electrode plates. It is possible to circulate along the perforated electrode plate to improve the bubble separation property on the entire surface of the perforated electrode plate and improve the water replacement efficiency among the plurality of perforated electrode plates.

Moreover, according to the hydrogen water generating apparatus according to claim 4, by pressurizing the water flow discharged from the pump in the gap between the plurality of porous electrode plates, the hydrogen generated in the porous electrode plates is under pressure. Since it was configured to dissolve in the water stream, more hydrogen can be dissolved in water.

Further, according to the hydrogen water generating apparatus according to claim 5, an electrode cover having an insulating property is arranged on the upper part of the porous electrode plate in the electrolysis part, and the electrode cover is formed on the opposed porous electrode plate.

The hydrogen water generating apparatus 100 according to the present embodiment accommodates and arranges a pump unit 20, an electrolysis unit 30, and a power supply unit 40 in a case 10 that can be immersed in a reservoir such as a bathtub. In addition, the electrolysis unit 30 is configured such that a plurality of porous electrode plates are arranged at regular intervals, and the water flow from the pump unit 20 is directed toward the plate surface of the porous electrode plate. Thereby, compared with the past, the fine bubble property of the hydrogen which water contains improves, and the hydrogen water which eased the bubble growth of hydrogen in water can be produced | generated.

Hereinafter, a specific aspect of the hydrogen water generator 100 shown in the drawings will be described.

The case 10 is formed in a watertight structure using a water-impermeable material such as a synthetic resin, so that water does not enter the case 10 except for the water passage 13 through which water flows from the inlet 11 to the outlet 12. The member seam is sealed with a sealing material or the like. In the example shown in FIG. 1, FIG. 2, etc., the upper case 10a and the lower case 10b are vertically combined to form a watertight interior, and a protective member 10c having a rib structure is mounted on the upper surface of the upper case 10a.

The protective member 10c has a base portion 10c1 extending so as to cover the upper surface of the upper case 10a, and a rib 10c2 erected on the upper surface of the base portion, and is opened at a portion facing the electrolytic portion 30 exposed on the upper surface of the upper case 10a. 10c3, and has an opening 10c4 at a portion facing the operation switch 15 provided on the upper surface of the upper case 10a. A rib 10c2 is installed on the opening 10c3, and ribs are arranged in parallel at regular intervals so that a human finger does not pass along the longitudinal direction of the electrolysis unit 30. The water flowing out from the electrolysis unit 30 can be ejected upward from the upper surface of the hydrogen water generator 100 while preventing contact.

Almost all of the electrical components of the hydrogen water generator 100 are disposed in the watertight portion of the case 10, but the porous electrode plates 31 to 33 constituting the electrolysis unit 30 are disposed outside the watertight portion. Specifically, it is disposed in the water passage 13.

The pump unit 20 is interposed in the middle of the water passage 13, and the internal water passage 21 of the pump unit 20 constitutes a part of the water passage 13. When the pump unit 20 is operated, a pump pressure is applied to the water in the internal water passage 21, and the water in the whole water passage 13 flows through the water passage 13 by this pump pressure, and water is sucked from the inlet 11. At the same time, water is discharged from the outlet 12. In the present embodiment, the built-in pump unit is described as an example. However, a pump unit may be provided outside the case 10 and connected to an external pump unit with a tube or the like to connect the water in the water passage 13. It is good also as a structure which applies a pump pressure to.

The inflow port 11 is provided with openings in recesses provided at the corners of the side surface and the lower surface of the case 10, and the outflow port 12 is provided on the upper surface of the case 10. By not providing the inflow port 11 and the outflow port 12 at positions along the lower surface of the case 10, it is not necessary to provide leg members that separate the lower surface of the case 10 from the inner bottom surface of the container by a certain distance. By providing the outlet 12 on the upper surface of the case 10, bubbles that are generated and grown in the electrolysis unit 30 and are rising away from the electrolysis unit 30 can be entrained in the water flow discharged from the hydrogen water generator 100. In addition, the inflow port 11 is provided with a filter 14 that prevents intrusion of dust, scale, hair, and the like, thereby preventing clogging and contamination of the water passage 13.

In addition, an operation switch 15 and an illumination / operation check LED 16 (Light Emitting Diode) are provided on the upper surface of the case 10. When the operation switch 15 is operated, various operation inputs such as power on / off of the hydrogen water generating apparatus 100, display ON / OFF of the illumination / operation check LED 16 described later, and switching of display colors can be performed. A charging terminal 17 of the power supply unit 40 configured to be able to store electricity is provided on the side surface of the case 10, and the charging terminal 17 is connected to a commercial AC power supply via an AC adapter or the like to charge the power supply unit 40. Can do.

Note that a cover member (not shown) for covering the charging terminal 17 is attached to the hydrogen water generating apparatus 100, and the hydrogen water generating apparatus 100 is immersed in water by attaching the cover member and covering the charging terminal 17. In this case, the charging terminal 17 is prevented from being short-circuited or leaked.

A control / charging board 18 as a control main body for electrically controlling the hydrogen water generating device 100 is fixedly installed in the watertight portion of the case 10. A number of wires extend from the control / charge board 18 and are connected to the pump unit 20, electrolysis unit 30, power supply unit 40, operation switch 15, and illumination / operation check LED 16, respectively. In the drawing, only the wiring between the electrolysis unit 30 and the control / charge board 18 is shown.

The wiring connected to the electrolysis unit 30 is not directly connected to the electrolysis unit 30 in the water passage 13, but is connected to the tips of the conductor rods 34 and 35 connected to the porous electrode plates 31 to 33. . The conductor rods 34 and 35 protrude into the watertight portion through the through hole 13a on the wall surface of the water passage 13. The porous electrode plates 31 and 33 are connected to one conductor rod (for example, the conductor rod 34), and the porous electrode plate 32 is formed with an insertion hole for the one conductor rod. On the other hand, the porous electrode plate 32 is connected to the other conductor rod (for example, the conductor rod 35), and the porous electrode plates 31 and 33 are formed with insertion holes for the other conductor rod. A space between the through hole 13a on the wall surface of the water passage 13 and the conductor rods 34 and 35 is sealed with a sealing material or the like. In the example shown in FIG. 5, a bolt is screwed onto the tip of the conductor rods 34 and 35 exposed to the watertight portion through the through hole 13 a, and a sealing material such as an O-ring is interposed between the bolt and the wall surface of the water passage 13. By doing so, the through hole 13a is sealed.

The water passage 13 has a pressure chamber 13b that gradually increases in width near the outflow port 12 in the vicinity of the outflow port 12, and the plurality of porous electrode plates 31 to 33 constituting the electrolysis unit 30 include the pressure chamber 13b. In the water passage 13 close to the wide opening of the water passage 13, each of the flow passage sections of the water passage 13 is disposed so as to close the whole. Thus, the water flowing through the water passage 13 always reaches the outlet 12 through the bubble passage holes 31a to 33a of the respective porous electrode plates 31 to 33. Further, by forming the outlet opening of the pressure chamber 13b to have a larger cross-sectional area than the water passage 13 near the pump unit 20, the supply port for supplying hydrogen water into a reservoir such as a bathtub is increased, and hydrogen water is generated. Diffusion of hydrogen water supplied from the apparatus 100 into the container is promoted. The shape of the pressure chamber 13b is not limited to the funnel-shaped widened shape, and various shapes are adopted as long as uniform water pressure is applied to the electrolysis unit 30 and hydrogen water diffusion from the outlet 12 can be promoted. Is possible.

The porous electrode plates 31 to 33 are formed in a plate shape from a conductive metal material such as titanium plated with gold or platinum, and a plurality of bubble circulation holes 31a to 33a penetrating the plate surface from the front to the back are provided. . The porous electrode plates 31 to 33 are fixed in the water passage 13 in a state where they are kept at a constant interval so as not to contact each other, and the power supply unit is connected to the porous electrode plates 31 to 33 via the wiring and the conductive rods 34 and 35 described above. Power is supplied from 40. The bubble circulation holes 31a to 33a are uniformly formed over the entire plate surfaces of the porous electrode plates 31 to 33.

A voltage is applied to each of the porous electrode plates 31 to 33 so that a potential difference is generated between adjacent plates. For example, when a high voltage is applied to the porous electrode plates 31 and 33, a low voltage is applied to the porous electrode plate 32. When a low voltage is applied to the porous electrode plates 31 and 33, a high voltage is applied to the porous electrode plate 32. As a result, electrolysis is performed between the surfaces of the porous electrode plates 31 to 33 facing the adjacent plates, and hydrogen (and oxygen) is generated near the plate surfaces of the porous electrode plates 31 to 33.

The porous electrode plates 31 to 33 block the wide opening of the pressure chamber 13b, and the pump unit 20 applies pump pressure to the water passage 13. Due to this pump pressure, the water that has flowed through the water passage 13 and reached the pressure chamber 13b spreads over the entire cross section of the flow path along the widened shape, and a water flow toward the plate surfaces of the porous electrode plates 31 to 33 is generated. By applying the pressure of the water flow to the plate surfaces of the porous electrode plates 31 to 33 that block the outlet 12 of the water channel 13, the bubbles of hydrogen and oxygen generated by electrolysis on the surface of the porous electrode plate are pushed away at the moment of electrolysis. There is an effect of taking it into the water flow, and bubbles of hydrogen contained in the water flowing out from the outlet of the hydrogen water generating device 100 are made fine. In addition, not only the visible hydrogen bubbles become microbubbles, but also the effect that hydrogen bubbles of invisible size and hydrogen before bubble growth are dissolved in the water flow is expected, for example, at the molecular level immediately after electrolysis The effect of being taken into the water stream and the effect of hydrogen being taken into the water stream with nanobubbles and microbubbles can also be expected. In addition, as shown by shading in FIG. 9, the water is pressurized by the resistance due to the bubble passage holes of the porous electrode plate disposed on the downstream side in the gap between the porous electrode plates on the upstream side in the pressure chamber 13b. Thus, hydrogen is forcibly dissolved, and the dissolved hydrogen concentration is improved. In FIG. 9, an electrolysis unit 30 including five porous electrode plates 31, 32, 33, 33-1, 33-2 is shown as an example in which more porous electrode plates are provided. Needless to say, it may be four, four, or five or more. Further, since the pressure chamber 13b is provided and the porous electrode plates 31 to 33 are provided so as to close the outlet 12 which is the outlet thereof, a substantially uniform water pressure is applied to the entire surface of the porous electrode plate 31, and the entire surface of the porous electrode plate 31 is provided. Water uniformly flows into the plurality of bubble circulation holes 31a, and water uniformly flows out from the plurality of bubble circulation holes 33a on the entire surface of the porous electrode plate 33. As a result, a water flow is formed in which the water flows evenly through each of the bubble circulation holes 31a to 33a formed on the entire plate surface of the porous electrode plates 31 to 33, and the plate is spread over the entire area of the porous electrode plates 31 to 33 in the plate surface direction. Water hardly stays near the surface. That is, the water replacement efficiency in the water passage 13 is improved in the vicinity of the plate surfaces of the porous electrode plates 31 to 33.

The bubble circulation holes 31a to 33a of the porous electrode plates 31 to 33 may be formed in an alternate positional relationship between adjacent porous electrode plates as shown in FIG. That is, in plan view, the bubble circulation holes 31a of the porous electrode plate 31 and the bubble circulation holes 32a of the porous electrode plate 32 are respectively formed in a partially overlapping positional relationship or a non-overlapping position. 32a and the bubble flow holes 33a of the porous electrode plate 33 are also formed in a partially overlapping positional relationship or a non-overlapping position, respectively.

In this way, when the bubble circulation holes 31a to 33a are formed in an alternate positional relationship between the adjacent porous electrode plates 31 to 33, the water passing through the porous electrode plates 31 to 33 flows in a zigzag manner. Water flows along the perforated electrode plate to every corner between 31 and 33, and the defoaming property can be improved over the entire surface of the perforated electrode plate. That is, the residence time of hydrogen (and oxygen) bubbles on the electrolytic plate surface is shortened, and the electrolytic plate surface is not easily covered with bubbles. This improves the electrolysis efficiency, makes it difficult for bubbles to grow on the surface of the electrolytic plate, makes hydrogen (and oxygen) released from the surface of the electrolytic plate fine, and dissolves hydrogen in the molecular level of hydrogen, nanobubbles and microbubbles. I can expect. As a result, the hydrogen dissolved amount of the water discharged from the hydrogen water generating apparatus 100 can be improved, and the hydrogen dissolved amount of water in a wide range in the container can be improved.

FIG. 10 is a diagram showing a flow of processing executed by the control unit 50 of the hydrogen water generating apparatus 100. The process shown in the figure is started by starting power supply from the power supply unit 40 to the control unit 50. The control unit 50 is configured by a control circuit such as a microcomputer mounted on the control / charge board 18 as the above-described control subject.

In the process shown in FIG. 10, the control unit 50 first determines whether or not an operation start operation input (for example, long press for 2 seconds or more) is received via the operation switch 15 (S1). When the operation start operation input is accepted (S1: Yes), the operation start process of the hydrogen water generator 100 is executed (S2), and when the operation start operation input is not accepted (S1: No), the operation start is started. Until the operation input is accepted, the determination in step S1 is periodically repeated.

The operation start process (S2) is mainly a power supply start to the porous electrode plates 31 to 33 and a power supply start to the pump unit 20. For example, when the porous electrode plates 31 and 33 are positive plates to which a high voltage is supplied, the porous electrode plates 32 are negative electrodes to which a low voltage is supplied. , 33 are negative plates fed with a low voltage, the porous electrode plate 32 is a positive plate fed with a high voltage. In the present embodiment, the former is called a normal electrolysis mode and the latter is called a reverse electrolysis mode. In this embodiment, it is the structure which switches a normal electrolysis mode and a reverse electrolysis mode every fixed time (mode duration). When power supply is started, the pump unit 20 applies a pump pressure to the water passage 13 to generate a water flow in the water passage 13.

Next, the control unit 50 determines the elapse of the mode duration (for example, 29 seconds) (S3). The controller 50 measures the continuous power supply time to the porous electrode plates 31 to 33 in any mode, and when this continuous power supply time exceeds the mode duration (S3: Yes), the electrolysis mode Is reversed (S4), and if the continuous power feeding time does not exceed the mode duration (S3: No), step S4 is skipped and the process proceeds to step S5. In addition, during mode switching, an energization stop time (for example, 1 second) for stopping energization of the porous electrode plates 31 to 33 is provided for a short time.

Thus, by reversing the electrolysis polarity by switching the electrolysis mode at regular intervals, the calcium carbonate scale adhering to the surface of the porous electrode plate serving as the cathode dissolves and is discharged by the water flow generated by the pump unit 20. . As a result, the electrolytic performance of the porous electrode plates 31 to 33 can be maintained and the life can be extended.

Next, the control unit 50 determines whether the automatic operation time has elapsed (S5). The control unit 50 measures the operation continuation time that has elapsed since the operation was started in step S2, and when the operation continuation time exceeds the automatic operation time (S5: Yes), the operation is stopped ( S6) If the operation continuation time does not exceed the automatic operation time (S5: No), the process proceeds to step S7. As described above, the hydrogen water generating apparatus 100 is configured to automatically stop the operation when a certain time (for example, 15 minutes) elapses after the operation starts.

In step S7, it is determined whether or not an operation stop operation (for example, long press for 2 seconds or more) has been performed on the operation switch 15, and when the operation stop operation is performed (S7: Yes), the operation is stopped (S6), and if the operation stop operation has not been performed (S7: No), the processes of steps S3 to S3 are repeatedly executed.

During operation, an operation display for turning on the illumination / operation check LED 16 may be performed. When a plurality of colors of LEDs are provided as the illumination / operation confirmation LED 16, the emission color may be switched at a constant period to emit light. Good. As the emission color switching timing, for example, the above-described mode switching timing can be used. Specifically, when the illumination / operation check LED 16 is lit in red in the positive electrolysis mode, for example, the illumination / operation confirmation LED 16 is turned off during the energization stop period, and then the illumination / operation is switched to the negative electrolysis mode at the same time. For example, the confirmation LED 16 may be lit in blue. Moreover, it is good also as a structure which switches a lighting color, when predetermined | prescribed operation input (for example, pressing operation for less than 2 second etc.) is performed with respect to the operation switch 15. FIG.

As described above, by controlling the electrolysis unit 30, the pump unit 20, and the illumination / operation check LED 16, the lifetime of the apparatus is maintained while preventing the calcium carbonate scale from adhering to the porous electrode plates 31 to 33 and maintaining high electrolysis performance. Can extend the service life. In addition, the lighting / operation check LED 16 can be turned on to let the user know the driving situation and create a visually interesting atmosphere as decorative lighting in the container.

In the first embodiment, in the pressure chamber 13b, the wide opening is closed by the three electrode plates of the porous electrode plates 31 to 33 and the five porous electrode plates of the porous electrode plates 31 to 33-2. In this way, it was decided to increase the dissolution of hydrogen in water by setting the gap between the porous electrode plates and the inside of the pressure chamber 13b to a pressurized atmosphere, but for example, downstream of each porous electrode plate, that is, above each porous electrode plate The internal pressure of the pressure chamber 13b may be increased by restricting the flow path.

Specifically, as shown in FIG. 11 (a), an electrolysis part cover body 30a covering the upper part of the electrolysis part 30 is provided, and a plurality of discharge holes 30b are formed in the top surface part of the electrolysis part cover body 30a. An electromagnetic valve 30c electrically connected to the control / charging board 18 for controlling opening / closing of some of the discharge holes 30b may be provided.

In this case, when the electromagnetic valve 30c is opened, the flow passage restriction of the water passage 13 is performed in the gap between the porous electrode plates as in the case shown in FIG. When the electromagnetic valve 30c is controlled to be closed by the control / charge board 18, the inner space portion of the electrolysis part cover body 30a corresponding to the downstream side of the electrolysis part 30 is shown by shading when the electromagnetic valve 30c is controlled to be closed. Thus, it can be under a pressurized atmosphere, and the dissolution efficiency of hydrogen in water can be further improved.

Further, it is not always necessary to use electrical means such as the electromagnetic valve 30c. As shown in FIG. 11B, a needle having a needle 30d disposed at a position facing the discharge hole 30b formed in the electrolysis part cover body 30a. The plate 30e is arranged, and the needle lifting screw 30f provided at a position where the user can operate is rotated, so that the needle 30d is manually moved in and out of the discharge hole 30b, thereby restricting the flow path. Also good.

Even in such a configuration, the needle 30d is allowed to enter the discharge hole 30b, whereby the inner space portion of the electrolysis part cover body 30a, which is the downstream side of the electrolysis part 30, particularly in the pressure chamber 13b, is placed in a pressurized atmosphere. And the efficiency of dissolving hydrogen in water can be further improved.

In the first embodiment, the pump unit 20 has been described as operating with a constant water supply amount. However, the water supply amount of the pump unit 20 can be changed, and the flow rate in the water passage 13 (pressure chamber 13b) can be adjusted. It is also good.

In the above-described example, the water flowing through the narrow electrode plate gap in the electrolysis unit 30 has a high flow rate. For example, hydrogen bubbles generated on the surface of the cathode plate are quickly separated in a small state immediately after the generation, and the water efficiently Will be dissolved.

Here, when the water supply amount of the pump unit 20 is reduced, the flow rate of water in the gap between the electrode plates becomes small, and hydrogen bubbles generated on the surface of the cathode plate are not immediately separated, but gradually accumulates with time. When the resistance force from the water flow becomes larger than the adhesion force of the bubbles to the cathode plate surface, it peels off from the cathode plate surface.

And the large hydrogen bubbles released in the bathtub quickly reach the hot water surface and diffuse into the bathroom.

In this case, although the efficiency of dissolving hydrogen in hot water in the bathtub cannot be expected as fine hydrogen bubbles, the hydrogen diffused in the bathroom is taken into the body by the breathing of the user while taking a bath, and has a more direct health promotion effect. It can be expected.

That is, the hydrogen water generating apparatus described in the present specification including the hydrogen water generating apparatus according to the first embodiment includes a pump unit 20 and a control unit (for example, a control / charging board) that controls the water supply amount of the pump unit 20. 18) may be provided with a bubble diameter adjusting means (bubble diameter adjusting unit), whereby the effect of the hot bath with high-concentration hydrogen water and the effect of hydrogen diffused in the bathroom It becomes possible to selectively enjoy the health promotion effect of both.

(2) Second embodiment:
Since the hydrogen water generating apparatus according to the present embodiment has the same configuration as the hydrogen water generating apparatus 100 according to the first embodiment described above except for the configuration of the electrolysis unit, the configuration other than the electrolysis unit is the first. Description will be made using the same reference numerals as in the embodiment.

FIG. 12 is a diagram for explaining the hydrogen water generating apparatus according to the present embodiment.

The electrolysis unit 30 is provided with a plurality of porous electrode plates 231 to 233 (the porous electrode plates 232 and 233 are not exposed in the drawing) at regular intervals. The porous electrode plates 231 to 233 are fixed in the water passage 13 in a state where they are kept at a fixed interval so as not to come into contact with each other. The point supplied with power from 40 is the same as in the first embodiment described above.

On the other hand, in the porous electrode plates 231 to 233 according to the present embodiment, the partition part that divides between the bubble circulation holes of the porous electrode plates 231 to 233 has a corner part that becomes a tip toward the water flow generated by the pump part 20. It has a polygonal cross section. That is, in each of the perforated electrode plates 231 to 233, each surface formed with the corners facing the bubble circulation holes on both sides of the partition part receives the water flow generated by the pump unit 20 toward each bubble circulation hole. It becomes an inclined surface inclined in the direction. Due to the water flow flowing along the inclined surface, the bubble releasing property of the bubbles generated on the surfaces of the porous electrode plates 231 to 233 is improved. In addition, since the surface between the bubble circulation holes of the porous electrode plates 231 to 233 is configured as another discontinuous surface across the corner, bubbles generated on one surface are generated on the other surface. The bubbles released from the porous electrode plates 231 to 233 are less likely to be coalesced with each other, and the bubbles can be expected to be made finer or dissolved in molecular level hydrogen, nanobubbles or microbubbles. Further, since the porous electrode plates 231 to 233 between the bubble circulation holes have corners directed toward the water flow, the water flow flowing through the bubble circulation holes of the porous electrode plates 231 to 233 becomes smooth and is farthest from the pump unit 20. The water force can be maintained until the gas circulation holes of the porous electrode plate 233 are circulated. In addition, since the corner portion has a small surface tension, the bubble releasing property of the bubbles generated at the corner portion between the bubble circulation holes of the porous electrode plates 231 to 233 that the water flow directly hits is improved. The metal lath plate described below as an example of the porous electrode plates 231 to 233 having such a polygonal cross section having a corner toward the water flow generated by the pump unit 20 is formed on the plate surface between the bubble circulation holes. is there.

FIG. 13 is a diagram for explaining the detailed shape of the porous electrode plates 231 to 233 made of metal lath plates. The perforated electrode plates 231 to 233 according to the present embodiment are formed of a metal lath plate formed in a rhombic mesh shape by making a cut in a thin metal plate and extending the thin metal plate in a direction substantially perpendicular to the cut direction. The perforated electrode plates 231 to 233 formed of metal lath plates are mesh members in which partition wires W are arranged in an intersecting manner, and openings surrounded by the partition wires W become bubble circulation holes 231a to 233a through which water flows. . The bubble circulation holes 231a to 233a are diamond-shaped, the first diagonal L1 is longer than the second diagonal L2, and the angles of the apexes H1 and H2 on the first diagonal L1 are the angles of the apexes H3 and H4 on the second diagonal L2. Is smaller than

As described above, the metal lath plate is provided with a plurality of broken-line cracks formed by intermittently cutting the thin metal plate, and the thin metal plate is extended in a direction substantially perpendicular to the cut direction so that the cut portion has a rhombic mesh shape. It is created by forming, and the connecting portion X between the breaks of the broken-line crack is located in the middle of the adjacent broken-line crack.

When the thin metal plates with cuts are elongated in the direction in which the broken-line cracks are juxtaposed, the linear portions between the fractured cracks are twisted so as to rotate about the length direction of the linear portions. For this reason, the section wire W having a substantially square cross section constituting the mesh of the metal lath plate has a rectangular inclined surface whose rectangular surface is inclined with respect to the surface direction of the porous electrode plates 231 to 233. In the present embodiment, the inclination angle θ with respect to the surface direction of the porous electrode plates 231 to 233 is set to approximately 45 °, and the rectangular inclined surfaces are substantially the same inclination with respect to the plate surfaces of the porous electrode plates 231 to 233.

In the perforated electrode plates 231 to 233 formed in this way, as shown in FIG. 14, the partition wires W between the bubble circulation holes have a polygonal cross section having corners directed to the water flow generated by the pump unit 20. Yes, the partition wire W has a rectangular inclined surface inclined with respect to the water flow. For this reason, the bubble releasing property of bubbles generated on the surfaces of the porous electrode plates 231 to 233 is improved. Moreover, since the side which goes to the water flow which the pump part 20 of the division wire W generate | occur | produces is comprised as another surface which is discontinuous on both sides of a corner | angular part, the bubble which generate | occur | produced on one surface is the bubble which generate | occur | produced on the other surface It is difficult to coalesce with each other, and bubbles released from the porous electrode plates 231 to 233 can be made finer, and hydrogen can be expected to be dissolved in molecular level hydrogen, nanobubbles and microbubbles. In addition, since the end of the corner of the partition wire W is oriented toward the water flow, the momentum of the water flow flowing through the bubble circulation holes of the porous electrode plates 231 to 233 is not easily inhibited by the partition wire W, and is the porous farthest from the pump unit 20. A certain amount of water can be maintained until the bubble circulation holes of the electrode plate 233 are circulated. Moreover, since the corner | angular part of the division wire W has small surface tension, the foaming property of the bubble which generate | occur | produces in the corner | angular part improves. In addition, the corner | angular part front-end | tip of the division wire W also has a function as a charge concentration part. The charge concentration portion will be described later in the fourth embodiment. That is, even when a metal lath plate is adopted as the porous electrode plate, it can be interpreted that a charge concentration portion is formed at the periphery of the bubble circulation hole in the porous electrode plate.

(3) Third embodiment:
The hydrogen water generating apparatus according to the present embodiment has the same configuration as the hydrogen water generating apparatus 100 according to the first embodiment described above except for the shape of the water channel, and the configuration other than the water channel is the first implementation. The description will be made using the same reference numerals as the form. FIG. 15 is a diagram for explaining the hydrogen water generation apparatus according to the present embodiment.

The water passage 313 according to the present embodiment has a pressure chamber 313b that gradually widens toward the outlet 12 near the outlet 12, and the plurality of porous electrode plates 31 to 33 constituting the electrolysis unit 30 are The water passage 313 close to the wide opening of the pressure chamber 313b is the same as the first embodiment described above in that it is disposed so that substantially the entire cross section of the water passage 313 is closed. As in the first embodiment, the shape of the pressure chamber 313b is not limited to the funnel-shaped widened shape, and an equal water pressure is applied to the electrolysis unit 30 to diffuse hydrogen water from the outlet 12 into the container. If promotion is possible, various shapes can be adopted.

A cylindrical water passage 313c that penetrates the side surface of the pressure chamber 313b and forms a part of the water passage communicating with the pump unit 20 extends to the vicinity of the center of the pressure chamber 313b, and the tip of the cylindrical water passage 313c is The pressure chamber 313b opens toward the reduced diameter portion 313d. That is, the water flowing in through the cylindrical water channel 313c is discharged toward the reduced diameter portion 313d of the pressure chamber. In the pressure chamber 313b, the diameter-reduced portion 313d side is closed and the diameter-expanded portion 313e side is opened toward the outflow port 12, but the diameter-expanded portion 313e is arranged so that the electrolysis unit 30 blocks the flow path. It is arranged. Accordingly, the water discharged from the cylindrical water passage 313c collides with the reduced diameter portion 313d of the pressure chamber 313b, and becomes a water flow that flows toward the enlarged diameter portion 313e along the wall surface of the pressure chamber 313b. A substantially uniform water flow is formed in the entire cross section of the water channel of the pressure chamber 313b in the vicinity of the enlarged diameter portion 313e by joining at the back side of the opening. Thereby, it is possible to realize a configuration in which substantially the same water pressure is applied to the entire surface of the porous electrode plates 31 to 33 of the electrolysis unit 30 disposed in the vicinity of the enlarged diameter portion 313e.

Further, in the example shown in FIG. 15, rectifying fins 313f1 to 313f4 are provided in order to improve the uniformity of the water flow in the entire cross section of the water channel of the pressure chamber 313b in the vicinity of the enlarged diameter portion 313e. That is, the rectifying fins 313f1 to 313f4 are erected so as to partition the bottom surface of the pressure chamber 313b. The water flow discharged from the tubular water channel 313c is divided by the rectifying fins 313f1 to 313f4 so that the water flow distributed according to the division ratio flows into each division, and the divided water flow collides with the reduced diameter portion 313d for each division. Thus, the water flow rises toward the perforated electrolytic plates 31 to 33 along the wall surface of the pressure chamber 313b, thereby improving the uniformity of the water flow in the vicinity of the enlarged diameter portion 313e in the entire cross section of the water channel of the pressure chamber 313b. The uniformity of the water pressure applied to the porous electrode plates 31 to 33 of the electrolysis unit 30 is improved.

The tip of the cylindrical water channel 313c may have a configuration in which an opening is directed to the other side wall of the pressure chamber 313b other than the reduced diameter portion 313d. For example, the cylindrical water channel 313c may be discharged toward an inclined surface forming a funnel shape or be used for a new collision. It is also conceivable that a wall surface is set up and discharged toward the wall surface. That is, it is possible to realize a configuration in which substantially the same water pressure is applied to the entire surface of the porous electrode plates 31 to 33 even if the opening is directed in various directions as long as the direction does not directly face the electrolysis unit 30.

As described above, even in a configuration in which water is ejected in a direction different from that of the porous electrode plates 31 to 33, the pressure of the water flow is applied to the plate surfaces of the porous electrode plates 31 to 33 that close the outlet 12 of the water passage 13, Hydrogen and oxygen bubbles generated by electrolysis on the surfaces of the electrode plates 31 to 33 can be taken into the water stream so as to push away at the moment of electrolysis, and include water flowing out from the outlet 12 of the hydrogen water generator 300. Hydrogen bubbles can be atomized and dissolved in molecular level hydrogen, nanobubbles and microbubbles.

(4) Fourth embodiment:
Next, a hydrogen water generator according to a fourth embodiment will be described with reference to FIGS.

As shown in FIG. 16 (a), the hydrogen water generator 400 according to the fourth embodiment is arranged at the bottom of the bathtub and supplies electrolytic hydrogen water into the bathtub, like the hydrogen water generator 100 and the like. It is a device for doing.

As shown in FIG. 16 (b), the hydrogen water generator 400 has the above-described water passage 13, control / charge board 18, pump, and the like inside an oval-shaped decorative casing 405 having no corners as a whole. A watertight hydrogen water generating main body 410 incorporating the unit 20, the electrolysis unit 30, the power supply unit 40 and the like is accommodated.

FIG. 17 is an exploded perspective view showing the structure of the hydrogen water generator 400. As can be seen from FIG. 17, the hydrogen water generating apparatus 400 includes a decorative housing 405 including a gripping plate 401, an upper decorative cover 402, and a lower decorative cover 403, and a hydrogen water generating main body that is a main body for generating hydrogen water. Part 410.

A makeup case 405 constituted by upper and lower uniting of the gripping plate 401, the upper decorative cover 402, and the lower decorative cover 403 is a power source in the hydrogen water generation main body 410 except that it is used for hydrogen water generation in a bathtub. It is configured to be placed on a tray-shaped charging base 406 that charges the unit 40.

The charging stand 406 is an upper opening box type, that is, a peripheral wall 406b is provided upright on the periphery of the charging base bottom plate 406a having a substantially square shape, and the inside thereof is configured in a tray shape. An energization connection portion 406c for supplying power to the power supply unit 40 in the hydrogen water generation main body 410 to be placed is formed in a convex shape.

Reference numeral 406d indicates an energization terminal projecting from the energization connection portion 406c, and the energization terminal 406d is connected to an energization wire 410e (shown by a broken line) via a transformer circuit board disposed inside the charging base 406. A plug (not shown) that can be connected to an outlet is connected to the end of the conducting wire 410e.

As will be described in detail later, when the hydrogen water generating apparatus 400 is immersed in the bathtub, a gap space (hereinafter referred to as a submerged space) inside the decorative housing 405 and outside the hydrogen water generating main body 410. It is formed so that hot and cold water penetrates. Therefore, although some water will remain temporarily in the hydrogen water generating apparatus 400 immediately after taking out from the bathtub, the charging stand 406 is formed in a tray shape with the peripheral wall 406b raised. Therefore, even when the battery is placed on the charging stand 406 immediately after being taken out from the bathtub, the residual water in the hydrogen water generator 400 is accumulated in the peripheral wall 406b and the surroundings are not wetted.

Further, the energization connecting portion 406c and the energization terminal 406d are formed at a position higher than the peripheral wall 406b. Therefore, even when a large amount of water is stored in the charging stand 406, the water volume overflows before reaching the energizing terminal 406d, so that the energizing terminal 406d can be prevented from being submerged.

By placing the hydrogen water generating device 400 on the charging stand 406 configured in this manner, the power is supplied to the power supply unit 40 in the hydrogen water generating main body 410, and the electric power is used in the hydrogen water generating device 400. Then, hydrogen is generated by electrolysis, and hydrogen is released into the bath water in the bath tub outside the hydrogen water generator 400 to dissolve the hydrogen in the bath water.

As shown in FIGS. 16 and 17, the gripping plate 401 is a hollow plate-like member that is slightly curved upward and has a shape in which the central part in the major axis direction of the ellipse is narrowed in the minor axis direction in plan view. In addition, when the hydrogen water generator 400 is transported, the narrowed portion functions as a gripping portion.

Further, as shown in FIG. 16 (b), the grip plate 401 has a substantially semicircular arc-shaped notch outlet 401 a formed between the grip plate 401 and the top decorative cover 402. The The notch discharge port 401 a is a part that functions as the outlet 12, and the electrolytic hydrogen water and bubbles discharged from the hydrogen water generation main body 410 are discharged.

In addition, a plurality of air holes 401b are formed on the top of the surface side of the gripping plate 401, and when the hydrogen water generator 400 sinks into the bathtub, water is slowly introduced into the hollow gripping plate 401. The hydrogen water generator 400 is configured to sink below the water surface while gradually reducing buoyancy.

In addition, on the back surface side of the gripping plate 401, that is, the portion facing the electrolysis unit 30 of the hydrogen water generation main body 410, which will be described later, the water flow and bubbles discharged from the electrolysis unit 30 are the two notch discharge ports 401a described above. A diverting portion 401c for diverting to is formed.

FIG. 19 is a cross-sectional view showing the upper half of the hydrogen water generator 400 cut at the position BB in FIG. 16 (b). As can be seen from FIG. 19, the back surface of the gripping plate 401 is formed in a slope shape that slopes upward from the central portion protruding downward toward both ends in the short axis direction, and the electrolytic hydrogen discharged from the electrolysis portion 30. The water branches along with the bubbles to both sides in the short axis direction at the central portion, flows along the back surface of the gripping plate 401 along the slope starting from the flow dividing portion 401c, and is discharged from the notch discharge port 401a with a slight directivity due to the water flow. .

As shown in FIG. 17, the upper decorative cover 402 is a hollow cosmetic cover with a substantially elliptical hemispherical shape in outer appearance that accommodates the substantially upper half of the hydrogen water generating main body 410, and has a hydrogen water on its top surface. A rectangular exposed opening 402a that exposes the electrolyzing unit 30 of the generation main body 410 and a plurality of circles that expose the illumination / operation check LED 16 and the operation switch 15 that are also disposed in the hydrogen water generation main body 410. A hole 402b is formed.

The lower decorative cover 403 is a decorative cover that accommodates the lower half of the hydrogen water generating main body 410, and is configured as an upward-opening box shape. It has a long elliptical shape.

A rectangular bottom opening 403a that exposes the bottom of the hydrogen water generating main body 410 is provided at the bottom of the lower decorative cover 403, and the periphery thereof is disposed at the bottom of the hydrogen water generating main body 410. A water intake opening 403 b that faces the inflow port 11 and a power receiving opening 403 c that faces the charging terminal 17 disposed at the bottom of the hydrogen water generation main body 410 are also formed.

Further, when the hydrogen water generator 400 is settled in the bathtub or pulled up from the bathtub at the lower portion of the side wall of the lower decorative cover 403 or the top surface periphery of the upper decorative cover 402, the air in the decorative casing 405 is removed. A slit 421 for allowing inflow and outflow and inflow and outflow of hot water is formed.

As described above, the hydrogen water generating apparatus 400 according to the present embodiment is formed so that hot water enters the water immersion space (for example, the water immersion space indicated by reference numeral 430 in FIG. 19) when immersed in the bathtub. Like the plurality of air holes 401b formed on the top of the surface side of the gripping plate 401, hot water is infiltrated into the submerged space from these slits 421, and the hydrogen water generator 400 is configured to sink below the water surface by reducing buoyancy. Yes.

Moreover, even if the user releases his / her hand in the water before the hydrogen water generating device 400 is placed at the bottom in the bathtub, the hydrogen water generating device 400 rapidly sinks to the bottom of the bathtub. In order not to collide, hot water gradually flows into the inundation space, and the air is gradually removed from the inundation space.

The hydrogen water generation main body 410 is a substantially rectangular parallelepiped member that functions as a hydrogen water generation main body having a configuration substantially similar to that of the above-described hydrogen water generation apparatus 100. An electrolysis part 30 having a substantially rectangular shape in plan view is disposed at a substantially central part of the upper surface, and four illumination / operation check LEDs 16 and an operation switch 15 are provided on the outer side of the long side of the electrolysis part 30. .

The illumination / operation confirmation LED 16 is exposed from the circular hole 402b of the upper decorative cover 402 and emits light upward at a predetermined irradiation angle. As shown in FIG. 19, this illumination / operation confirmation LED 16 emits light. LED16 is arrange | positioned in the position which cross | intersects the bubble and water flow discharge | released, directing the light radiate | emitted from the illumination / operation check LED16 from the notch discharge port 401a to the direction along the slope of the flow dividing part 401c.

Therefore, the light emitted from the illumination / operation check LED 16 is visually recognized by the user in a state of being scattered by the water stream containing hydrogen bubbles, and the user visually observes the scattering state of the light. It is possible to confirm the generation state and spread of a water stream containing fine bubbles.

In addition, since the light scattered by the water flow containing bubbles changes in the bathtub, a fantastic atmosphere can be created in the bathroom, and the user can relax and provide a comfortable bath time. . That is, the illumination / operation check LED 16 functions as a light emitting unit (light emitting unit) that emits light in a direction intersecting with the water flow flowing out from the outlet.

Returning to the description of FIG. 17, at the bottom of the hydrogen water generation main body 410, an inlet 11 for collecting water taken by filtering the water supplied into the hydrogen water generation main body 410 through the filter 14 and a hydrogen water generation device 400 are provided. A charging terminal 17 is provided for contacting and receiving power through the power receiving opening 403c of the lower decorative cover 403 when it is placed on the charging base 406.

As for the internal configuration of the hydrogen water generation main body 410, as shown in FIG. 18, a functional unit 422 including the control / charging board 18, the pump unit 20, and the power supply unit 40, and an upper case that houses the functional unit 422. 410a and lower case 410b, and the electrolysis part 30 are comprised.

Since the functional unit 422 is substantially the same as the hydrogen water generating device 100 described above, the description thereof is simplified. However, based on the control of the control / charge board 18, the power unit 40 obtains electric power to drive the pump unit 20 and Then, electric power is supplied to the electrolysis unit 30 with a predetermined polarity. Moreover, the water flow path 13 which distribute | circulates water through the pump part 20 is also provided.

The lower case 410b is a case for accommodating the substantially lower half of the functional part, and is formed in a box shape having a substantially rectangular shape in plan view and having an upper opening.

A lower open inverted box type upper case 410a is placed and fixed in a sealed state on the upper part of the lower case 410b in a state where the functional part 422 is accommodated. That is, the lower case 410b and the upper case 410a are sealed and united with each other via the packing 423 arranged at the peripheral edge.

Therefore, the bath water does not enter the lower case 410b and the upper case 410a even if the hydrogen water generator 400 is submerged in the bath tub.

In the upper center of the upper case 410a, an electrolysis part accommodating concave part 424 is formed. An opening 425 of the water passage 13 extending from the pump portion 20 is opened upward in the electrolysis portion housing recess 424, and further, the electrolysis portion 30 is disposed above the opening 425 of the water passage 13. Is stored. At this time, a pressure chamber 13 b that forms a water passage end is formed below the electrolysis unit 30.

In addition, on the left and right sides of the electrolytic part receiving recess 424 of the upper case 410a, when the upper case 410a is disposed on the functional part 422, the conductor rods 34 erected on the charging board 18 for energizing the electrolytic part 30; 35 is configured to be suspended in a watertight manner. The conductor rods 34 and 35 are electrically connected to the electrolysis unit 30 in the peripheral surface portion, and the lower end portion is connected to the control / charge board 18 disposed in the function unit 422 to supply power via the conductor rods 34 and 35. The unit 40 is configured to be able to supply power to the electrolytic unit 30. In other words, the power supply unit 40 is electrically connected to the electrolysis unit 30 from the power supply unit 40 so as to be electrolyzed. In the figure, reference numerals 34a and 35a denote holding members for alternately setting different porous electrodes, which will be described later, to contact or non-contact with each conductor rod 34, 35.

The electrolysis unit 30 includes a laminated electrode body 426 constituted by five upper and lower laminated porous electrode plates 31, 32, 33, 33-1, and 33-2, which are maintained at a predetermined interval. A voltage is applied to the plates alternately so as to be a high potential and a low potential, and electrolysis of bath water occurs between the opposing plate surfaces to generate hydrogen and oxygen near the plate surfaces.

Specifically, hydrogen and oxygen bubbles generated by electrolysis on the surfaces of the porous electrode plates 31, 32, 33, 33-1, 33-2 are converted into a water flow in a fine state by a water flow of pressure water from the pump unit 20. It is swept away to become dissolved hydrogen in which fine hydrogen is dissolved.

In particular, in the present invention, by adjusting the flow rate of the water flow from the pump unit 20 as described above, it is possible to adjust the time until bubbles that gradually increase due to electrolysis are washed away in the water and adjust the bubble diameter. is there.

In this way, when the bubble diameter can be adjusted, if the bubble diameter is increased, it can be removed from the water as soon as possible and released into the air quickly. The hydrogen bubble state can be maintained.

Therefore, by adjusting the flow velocity of the water flow from the pump unit 20 and adjusting the hydrogen bubble diameter, hydrogen water that matches the purpose of use of the hydrogen water generator can be obtained.

In other words, the bubbles receive resistance due to the water flow while attached to the electrode plate, and are peeled off when the peeling force generated by the resistance exceeds the adhesion force to the electrode plate, but the flow velocity is changed. In this way, a peeling force exceeding the adhesive force is generated while the bubbles are small, releasing fine bubbles in water, or a peeling force exceeding the adhesive force when the bubbles grow large and the surface area increases over time. The large bubbles can be liberated in the water, and the bubble diameter of the released hydrogen gas can be freely adjusted.

In addition, when the flow velocity of the water flow is high, hydrogen bubbles generated on the plate surface of the cathode plate are generated in the porous edge portion (edge portion) when the water flow flows in a zigzag state between the electrode plates opposed to each other. The injection function of the water flow that is generated in this way produces the effect of being refined by shearing force and efficiently dissolved in water.

In addition, a substantially rectangular plate-shaped electrode cover 427 made of an insulating material such as resin is disposed above the laminated electrode body 426. The electrode cover 427 has a role of protecting the electrode from being directly touched when the user accidentally inserts a limb through the notch discharge port 401a shown in FIG. 16B. A large number of holes 427a are regularly formed in the same manner as the porous electrode plate so as not to hinder the release of electrolytic hydrogen water and bubbles generated in the laminated electrode body 426.

In particular, the numerous holes 427 a formed in the electrode cover 427 are arranged in a staggered positional relationship with respect to the uppermost porous electrode plate 31 as in the positional relationship of the holes between the opposed porous electrode plates. Yes.

Therefore, as shown in FIG. 20 (a), when there is no electrode cover 427, for example, when a small piece 428 having conductivity falls on the laminated electrode body 426, two opposing porous sheets each having different polarities. Although there is a possibility of short-circuiting in contact with the electrode plate, if the electrode cover 427 is provided as in the hydrogen water generator 400 according to the present embodiment, the small piece 428 may be a porous electrode plate as shown in FIG. Even if it contacts 31, the other electrode cover 427 is not energized and does not have electrical conductivity, so it will not be short-circuited, and higher safety can be ensured.

Further, as a feature of the laminated electrode body 426 of the hydrogen water generator 400 according to the present embodiment, as shown in the enlarged view of FIG. 20B, the peripheral edge of the bubble circulation hole 431 of each porous electrode plate has a sharp shape. The charge concentration portion 432 is formed. In the enlarged view of FIG. 20B, the charge concentrating portion 432 is schematically shown exaggerated for easy understanding of the configuration, and the size and the size of each porous electrode plate are related to each other. The number is not always accurate.

In the present embodiment, each porous electrode plate is formed by forming a platinum plating layer 433b on the surface of a titanium substrate 433a. The platinum plated titanium substrate thus formed is punched and punched. As a result, a porous electrode plate having the bubble circulation holes 431 is formed.

Therefore, an edge-shaped charge concentration portion 432 is formed at the periphery of the formed bubble circulation hole 431 by the punch penetrating the platinum-plated titanium substrate during the punching process.

The charge concentration unit 432 has a role of generating hydrogen bubbles having a bubble diameter that is visible to the user when the hydrogen water generator 400 is used.

Originally, if electrolyzed hydrogen water containing hydrogen is produced by electrolyzing the electrolyzed water in the bath, the smaller the diameter of the hydrogen bubbles, the higher the dissolution efficiency, which is preferable.

However, when only extremely small-sized bubbles such as nanobubbles are generated, the user of the hydrogen water generating apparatus 400 cannot visually recognize the state in which bubbles are generated, and feels that bathing is performed with electrolytic hydrogen water. There is a problem that it is difficult to obtain.

Therefore, in the hydrogen water generation apparatus 400, a sharp charge concentration portion 432 is provided at the periphery of the bubble circulation hole 431, and the charge is concentrated on the charge concentration portion 432 so as to partially promote electrolysis, so that it is visually recognized as cloudy. Hydrogen bubbles that can be generated are generated.

By adopting such a configuration, it is possible to generate a lot of hydrogen bubbles that can be visually recognized by the user even though the solubility in water is relatively high. You can feel that you are bathing in hydrogen water.

The charge concentration portion 432 is formed by punching a platinum-plated titanium substrate. However, if the sharp charge-concentration portion 432 is provided, the platinum substrate subjected to the platinum processing is punched. Each porous electrode plate may be used. However, it should be noted that if the plating process is performed after drilling, the sharply formed edge portion becomes dull and the generation efficiency of hydrogen bubbles that can be visually recognized as cloudy may be reduced.

Further, in the present embodiment, the charge concentration portion 432 is formed by punching, but is not necessarily limited to punching processing. If the sharp charge concentration portion 432 is formed, the formation method is known. Any method is applicable.

Therefore, in the enlarged view of FIG. 20B, the charge concentration portion 432 is formed only on one side surface of the hole periphery of each porous electrode plate, but the charge concentration portion 432 may be provided on both side surfaces of the hole periphery. Of course.

Next, the electrical configuration of the hydrogen water generating apparatus 400 according to the present embodiment will be described. First, here, in order to facilitate understanding of the configuration, some characteristic functions of the hydrogen water generating apparatus 400 are described. Mention.

The hydrogen water generator 400 has a function of releasing difficult bubbles to peel off, a polarity reversal function, and a short-circuit prevention function as notable functions.

First, the difficult-to-separate bubble releasing function is a function to release the difficult-to-separate bubbles generated on the electrode surface and dissipate them from the notch discharge port 401a on a water stream.

As described above, the hydrogen water generating apparatus 400 causes the pump unit 20 to generate a water flow toward the plate surfaces of the porous electrode plates 31, 32, 33, 33-1 and 33-2 constituting the laminated electrode body 426. The hydrogen bubbles generated on the surface of each porous electrode plate are efficiently peeled and diffused into the bath.

However, in the diligent research conducted by the present inventors for many years, the surface of the electrode plate is mixed with a large number of easily generated hydrogen bubbles (hereinafter, also referred to as easy-to-peel bubbles), and from the electrode surface. It has been newly found that hydrogen bubbles that are difficult to peel off are generated at a predetermined rate.

The majority of the easy-to-peel bubbles can be easily peeled and diffused from the electrode surface even by a stable water flow generated by the pump unit 20, but the difficult-to-peel bubbles are not easily peeled by a constant flow of flowing water.

Therefore, difficult-to-separate bubbles generated at a constant rate over time gradually occupy a large area on the electrode surface as the electrolysis time elapses, which contributes to a decrease in electrolysis efficiency.

Therefore, in the hydrogen water generating apparatus 400 according to the present embodiment, the control unit controls the pump unit 20 to change the flow rate of the water flow during electrolysis, and changes the water flow resistance against the difficult-to-peel bubbles to separate the water. This facilitates the function of releasing bubbles that are difficult to peel off.

More specifically, during electrolysis, the controller 20 repeatedly switches and controls the pump unit 20 between a relatively long operation state that generates a water flow and a relatively short stop state that does not generate a water flow. Intermittent operation.

In this way, by performing a peeling cycle consisting of an operating state and a stopped state during electrolysis in the pump unit by the control unit, peeling that has been difficult until now when the operation state is resumed after the stopped state Difficult bubbles can be peeled off from the electrode surface, and an area effective for electrolysis on the surface of each porous electrode plate can be secured to maintain electrolysis efficiency.

Note that the presence of bubbles that are difficult to peel off is not necessarily an obstacle to the hydrogen water generator 400, but it also exhibits an extremely excellent effect after peeling from the electrode surface.

The released difficult-to-peel bubbles are bubbles that have not been easily detached from the electrode surface, that is, bubbles that have adhered to the electrode surface for a long time, and therefore the bubble diameter is larger than that of the easily-peeled bubbles.

Therefore, after being released into the water, a relatively large buoyancy is obtained, and it quickly reaches the surface of the water and diffuses into the vapor phase of the bathroom. This diffused hydrogen is taken directly into the body through the lungs by the user's breathing, and in addition to the effect of hydrogen water generated in the bathtub, a more efficient redox effect can be expected. .

In addition, many of the easily peelable bubbles are so-called nanobubbles, and it is difficult for the user to visually observe the hydrogen bubbles. However, since the difficultly peelable bubbles have a larger bubble diameter than the easily peelable bubbles, the user can visually confirm the bubbles. It is possible, and by making the generation of hydrogen visually feel, the redox effect by hydrogen can be further promoted from a mental aspect.

That is, in the hydrogen water generating apparatus 400 according to the present embodiment, in order to intentionally collect and release large bubbles due to bubbles that are difficult to peel, the peeling cycle is repeatedly performed to restart the pump unit 20 regularly or irregularly. It can also be understood that it is provided with a difficult-to-peel bubble releasing means (a difficult-to-peel bubble releasing part).

The time ratio between the operating state and the stopped state of the pump unit 20 constituting the peeling cycle is not particularly limited as long as the operating state is relatively long and the stopped state is short. Further, the time for one peeling cycle is not particularly limited.

For a comprehensible example to understand the configuration, the time for one cycle of the peeling cycle can be 30 to 120 seconds, and the time distribution between the operating state and the stopping state is 57 to 59.5: Can be 3 to 0.5. More specifically, the time for one cycle of the peeling cycle is 30 seconds to 120 seconds, preferably 45 seconds to 90 seconds, while the time for stopping is 0.5 seconds to 3 seconds, and one cycle of the peeling cycle. The remaining time obtained by subtracting the time for the stop state from the time can be set as the operation time.

The polarity reversal function is a function for preventing mineral components such as calcium dissolved in the water to be electrolyzed, in particular, metal ions present in a cation state in water as a scale during electrolysis.

In particular, in the hydrogen water generator 400 according to the present embodiment, the polarity is reversed every predetermined cycle of the peeling cycle.

Therefore, since the porous electrode plate functioning as the cathode is switched to the anode, and the porous electrode plate functioning as the anode is switched to the cathode every predetermined time, the deposition of the scale becomes substantially uniform for each porous electrode plate. Since the deposited scale is redissolved in water and the scale is removed on the porous electrode plate switched to the anode, it is possible to suppress a reduction in electrolytic efficiency due to scale adhesion.

The short-circuit prevention function is a function for preventing a short circuit between electrodes due to polarity reversal and protecting a circuit for switching electrodes.

As described above, the laminated electrode body 426 is configured by arranging a plurality (five) of porous electrode plates 31, 32, 33, 33-1, and 33-2 so as to face each other at a constant interval. Electrolysis is performed by alternately applying positive and negative voltages to each porous electrode plate.

Here, paying attention to any pair of opposed porous electrode plates applied positively and negatively among these porous electrode plates, when the supply of power to the porous electrode plates is stopped, the potential difference between the porous electrode plates is between them. Although it seems that it is solved by conducting through the existing water, it is clear from the study by the present inventors that in reality, a considerable potential difference is maintained between the respective porous electrode plates. It has become.

This is because the electrolyzed water has a capacity when it exists between the porous electrode plates, and this knowledge is also an event newly found by further analysis by the present inventors.

If the electrodes are switched and power is supplied in such a state, the state is substantially the same as the short-circuited state, and there is a risk of damaging the circuit that switches the electrodes. . In particular, when a switching circuit is realized by a semiconductor element such as an FET, there is a problem that the possibility of inducing a failure is increased.

Therefore, in the hydrogen water generating apparatus 400 according to the present embodiment, when switching the polarity, first, the supply of power to each porous electrode plate is stopped, and further, fresh water that has not been electrolyzed by the pump unit 20 is supplied. The polarity is switched after a lapse of a predetermined time of about 0.3 seconds to 2 seconds (hereinafter also referred to as a water flow replacement time) in which the water between the porous electrode plates is replaced with fresh water.

By adopting such a configuration, the capacity between the porous electrode plates can be reduced, and the potential difference between the porous electrode plates can be eliminated to a negligible level, thereby preventing a substantial short-circuit state during polarity switching. Alternatively, as an allowable level, damage to a circuit that performs electrode switching can be suppressed.

Also, it is desirable that the timing of switching the polarity is in a state where there are few bubbles that are difficult to peel off immediately after the pump unit described above is restarted from the viewpoint of circuit protection.

In this respect, since the hydrogen water generating apparatus 400 reverses the polarity every predetermined cycle of the peeling cycle, it is easy to measure the timing of switching the polarity immediately after the peeling cycle starts, and the circuit can be protected steadily. Since the flow rate may not be sufficiently stable immediately after the pump unit 20 is restarted, the flow rate of the water flow is stabilized prior to stopping the supply of power to each porous electrode plate when switching the polarity. A time of about 0.3 second to 2 seconds (hereinafter also referred to as a water flow stabilization time) may be provided.

Next, based on the description of these functions, the electrical configuration of the hydrogen water generator 400 according to this embodiment will be described with reference to FIG. In the hydrogen water generator 400 according to the present embodiment, the separation cycle is set to 60 seconds, ie, the operation state time of 58 seconds and the stop state time of 2 seconds, the polarity is switched every five cycles of the separation cycle, and the water flow stabilization time is The description will be made on the assumption that the electrolysis is automatically terminated in about 15 minutes, which is 0.5 seconds, the water flow replacement time is 0.5 seconds, and the separation cycle is 15 times. However, the present invention is not limited to this.

FIG. 21 is an explanatory diagram showing an electrical configuration of the hydrogen water generator 400. The control unit 440 constructed on the control / charge board 18 includes a CPU 441, a ROM 442, a RAM 443, an EEPROM 444, an RTC 446, and the like as its components, and can execute a program necessary for the operation of the hydrogen water generator 400.

Specifically, the ROM 442 stores programs and the like necessary for the processing of the CPU 441, and the RAM 443 functions as a temporary storage area when the programs and the like are executed.

For example, in a predetermined area of the ROM 442, in addition to a program for realizing processing, a value of an operating state time (58 seconds) that is a time for maintaining the pump unit 20 in an operating state, and the pump unit 20 in a stopped state. Stop time value (2 seconds), water stabilization time value (0.5 seconds), water flow replacement time value (0.5 seconds), switching gap time value (0.1 seconds), resumption of current The value of the waiting time (0.1 seconds) is stored. Needless to say, the values in parentheses in this paragraph are set values in the present embodiment, and can be changed as appropriate according to the specifications.

Further, for example, in a predetermined area of the RAM 443, a “polarity reversal flag” indicating whether or not to reverse the polarity, a “polarity switching counter” for counting the number of cycles of the peeling cycle for polarity switching, and for completion of electrolysis The “cycle number counter” that counts the number of cycles of the peeling cycle, the “interruption flag” that is referred to when the operation switch 15 is pressed for a long time during the operation of the hydrogen water generator 400 and the electrolysis is interrupted are stored. The

In addition, the EEPROM 444 stores which conductor rod was the anode when the electrolysis was interrupted (in this embodiment, which one of the two types of anode signals described later was emitted). Or the number of cycles at that time is stored. The EEPROM 444 functions as a non-power source storage unit that retains memory even after power supply is cut off. The EEPROM 444 is referred to by the CPU 441 at the time of restart, and restarts simultaneously according to the polarity and the number of cycles at the time of interruption. And the number of stripping cycles performed varies.

An RTC (Real Time Clock) denoted by reference numeral 446 is used to generate a clock pulse serving as a reference for executing an interrupt process described later. Even in a state where the processing is being executed, the CPU 441 interrupts the processing according to a clock pulse generated every predetermined cycle (for example, 2 milliseconds) from the RTC 446 and executes an interrupt processing.

The control unit 440 is connected to the operation switch 15, the LED 16, the pump unit 20, the power supply unit 40, the first conductor rod 34, and the second conductor rod 35, and is referred to according to the program execution status in the controller 440. Or is configured to be controlled and driven.

For example, the control unit 440 transmits a pump unit operation signal to the pump unit 20. The pump unit 20 is configured to operate in accordance with the state of the pump unit operation signal. When the pump unit operation signal is transmitted (ON state), the pump unit 20 operates and is transmitted. When not in the state (OFF state), the pump unit 20 stops.

Also, the control unit 440 is provided with a polarity switching circuit 445. The polarity switching circuit 445 receives the first conductor rod anode signal, the second conductor rod anode signal, and the voltage application signal emitted from the CPU 441, and supplies the power from the power supply unit 40 to the first conductor rod 34 and the second conductor rod. 35, and switching between positive and negative polarities of the first conductor rod 34 and the second conductor rod 35 is performed. Specifically, the polarity switching circuit 445 that has received the first conductor rod anode signal applies a voltage so that the first conductor rod 34 serves as an anode and the second conductor rod 35 serves as a cathode, and the second conductor rod anode signal is applied. When receiving, a voltage is applied so that the first conductor rod 34 serves as a cathode and the second conductor rod 35 serves as an anode. In addition, the polarity switching circuit 445 that has received the voltage application signal supplies power to each conductor bar in accordance with the received anode signal.

Next, processing executed in the control unit 440 will be described with reference to FIGS. FIG. 22 is a flowchart showing main processing executed by the CPU 441 of the control unit 440, and FIGS. 23 to 26 are flowcharts showing processing in each subroutine.

As shown in FIG. 22, in the main process, the CPU 441 first determines whether or not the operation switch 15 has been turned on (pressed down) (step S11). Here, when it is determined that the operation switch 15 is not turned ON (step S11: No), the CPU 441 returns the process to step S11 again. On the other hand, if it is determined that the operation switch 15 has been turned ON (step S11: Yes), the CPU 441 moves the process to step S12.

In step S12, the CPU 441 executes startup processing. In the start-up process, the CPU 441 refers to the EEPROM 444 and reads the type of anode signal and electrode switching counter value transmitted at the end of the previous time. Here, it is assumed that the previous termination was not due to interruption, and the termination was performed in a state where the second conductor rod anode signal was being transmitted, and in the start-up processing, the CPU 441 outputs the first conductor rod anode signal. Decide to send. Further, in the startup process, various counters and flag values in the RAM 443 are reset. When the CPU 441 refers to the EEPROM 444 and it is stored that the interruption flag is in the ON state, the CPU 441 stores the electrode switching counter value read from the EEPROM 444 in a predetermined address on the RAM 443 in the activation process. Is written, and it is determined that the anode signal of the read type is transmitted.

Next, in step S13, the CPU 441 performs an initial pump driving process. This initial pump drive process is a process for forming a water flow between the porous electrode plates prior to the start of electrolysis (for example, 1 to 3 seconds before the energization start process described below). Is sent to place the pump unit 20 in an operating state.

Next, in step S14, the CPU 441 executes energization start processing. In the energization start process, the CPU 441 transmits the anode signal of the type determined in the start-up process in step S12 and the voltage application signal to the polarity switching circuit 445, so that between the first conductor bar 34 and the second conductor bar 35, that is, A voltage is applied between the porous electrode plates with a predetermined polarity.

Next, the CPU 441 executes pump drive processing and starts measuring time (step S15). In this pump driving process, the CPU 441 transmits a pump unit operation signal to the pump unit 20 to place the pump unit 20 in an operating state. If the pump unit operation signal has already been transmitted in step S13, the pump unit operation signal is transmitted as it is.

Next, in step S16, the CPU 441 refers to a predetermined address in the RAM 443 and determines whether or not the polarity inversion flag is ON. If it is determined that the polarity reversal flag is not ON (S16: No), the CPU 441 moves the process to step S19. On the other hand, if it is determined that the polarity inversion flag is ON (S16: Yes), the CPU 441 moves the process to step S17.

In step S17, the CPU 441 performs polarity inversion processing. This polarity inversion processing is processing for switching the polarity of the voltage applied to the first conductor rod 34 and the second conductor rod 35, and will be described later with reference to FIG.

Next, the CPU 441 turns off the value of the polarity inversion flag stored at a predetermined address in the RAM 443 (step S18), and moves the process to step S19.

In step S19, the CPU 441 refers to the timer that started timing in step S15, and determines whether or not the operating state time (58 seconds in this embodiment) has elapsed. If it is determined that the operating state time has not elapsed (step S19: No), the CPU 441 returns the process to step S19. On the other hand, when determining that the operating state time has elapsed (step S19: Yes), the CPU 441 moves the process to step S20.

In step S20, the CPU 441 adds 1 to the electrode switching counter stored in the predetermined address of the RAM 443 and adds 1 to the cycle number counter.

Next, the CPU 441 refers to a predetermined address in the RAM 443 and determines whether or not the value of the cycle number counter is 15 (step S21). If it is determined that the value of the cycle number counter is 15 (step S21: Yes), the CPU 441 executes an end process (step S22) and finishes a series of programs (or starts the main process). Return to.) On the other hand, when it is determined that the value of the cycle number counter is not 15 (step S21: No), the CPU 441 executes the pump stop process (step S23), and returns the process to step S15 again. Note that the termination process in step S22 and the pump stop process in step S23 will be described later with reference to FIGS.

Next, the interrupt process will be described with reference to FIG. The CPU 441 may interrupt the process and execute the interrupt process even when the process is being executed. The following interrupt processing is executed in accordance with clock pulses generated from the RTC 446 every predetermined cycle (for example, 2 milliseconds).

In the interrupt process, the CPU 441 determines whether or not the operation switch 15 is in the long-pressed state (step S31). If it is determined that the operation switch 15 is not in the long-pressed state (step S31: No), the CPU 441 returns the process to the address before branching. On the other hand, if it is determined that the operation switch 15 is in the long-pressed state (step S31: Yes), the CPU 441 moves the process to step 32.

In step S32, the CPU 441 refers to a predetermined address in the RAM 443 and performs writing to set the value of the interruption flag to ON.

Next, in step S33, the CPU 441 executes an end process (described later), refers to a predetermined address in the RAM 443 again, writes the interrupt flag to OFF, and finishes the execution of a series of programs (or the main process). Return to start.)

Next, the pump stop process executed in step S23 of the main process will be described with reference to FIG.

In the pump stop process, the CPU 441 stops the pump unit 20 by stopping sending the pump unit operation signal to the pump unit 20 (step S41).

Next, the CPU 441 determines whether or not the stop state time (2 seconds in the present embodiment) has elapsed since the stop of the pump unit operation signal transmission (step S42). If it is determined that the stop state time has not elapsed (step S42: No), the CPU 441 returns the process to step S42 again. On the other hand, when it is determined that the stop state time has elapsed (step S42: Yes), the CPU 441 refers to a predetermined address in the RAM 443 and determines whether or not the value of the electrode switching counter is 5 (step). S43).

When it is determined that the value of the electrode switching counter is 5 (step S43: Yes), the predetermined address in the RAM 443 is referred to, the value of the polarity inversion flag is turned ON, and the value of the polarity switching counter is changed. Reset (step S44) and return the processing to the address before branching. On the other hand, when it is determined in step S43 that the value of the electrode switching counter is not 5 (step S43: No), the CPU 441 returns the processing to the address before branching.

Next, the polarity reversal process executed in step S17 of the main process will be described with reference to FIG.

In the polarity inversion process, the CPU 441 determines whether or not the water flow stabilization time (0.5 seconds in this embodiment) has elapsed since the time measurement was started in step S15 (step S51). If it is determined that the water flow stabilization time has not elapsed (step S51: No), the CPU 441 returns the process to step S51. On the other hand, when determining that the water flow stabilization time has elapsed (step S51: Yes), the CPU 441 moves the process to step S52.

In step S52, the CPU 441 stops sending the voltage application signal to the polarity switching circuit 445 and performs energization stop processing (step S52).

Next, the CPU 441 determines whether or not a time (1 second in the present embodiment) of the water flow stabilization time and the water flow replacement time (0.5 seconds in the present embodiment) has elapsed since the start of timing. If it is determined that the sum time has not elapsed (step S53: No), the CPU 441 returns the process to step S53. On the other hand, if it is determined that the sum time has elapsed (step S53: Yes), the CPU 441 stops the anode signal that has been sent (step S54).

Next, the CPU 441 determines whether or not the sum of the water flow stabilization time, the water flow replacement time, and the switching gap time (0.1 seconds in this embodiment) has elapsed since the start of time measurement (step S55). If it is determined that the sum time has not elapsed (step S55: No), the CPU 441 moves the process to step S55 again. On the other hand, if it is determined that the sum time has elapsed (step S55: Yes), the CPU 441 uses a different type of anode signal from the previously sent anode signal, that is, the previously sent anode signal. If is the first conductor rod anode signal, transmission of the second conductor rod anode signal is started, and if the previously sent anode signal is the second conductor rod anode signal, transmission of the first conductor rod anode signal is started (step S56). The process proceeds to step S57.

In step S57, the CPU 441 determines whether or not the sum of the water flow stabilization time, the water flow replacement time, the switching gap time, and the energization resumption waiting time (0.1 seconds in this embodiment) has elapsed since the start of timing. If it is determined that the sum time has not elapsed (step S57: No), the CPU 441 returns the process to step S57 again. On the other hand, when determining that the sum time has elapsed (step S57: Yes), the CPU 441 moves the process to step S58.

In step S58, the CPU 441 sends a voltage application signal to the polarity switching circuit 445 to perform energization start processing, and returns the processing to the address before branching.

Next, the termination process executed in step S22 of the main process and step S33 of the interrupt process will be described with reference to FIG.

In the termination process, the CPU 441 refers to a predetermined address in the RAM 443 and determines whether or not the value of the interruption flag is ON (step S61). If it is determined that the interrupt flag is ON (step S61: Yes), the CPU 441 stops the voltage application signal sent to the polarity switching circuit 445 and stops the energization (step S62). After performing, the process proceeds to step S66. On the other hand, when determining that the interruption flag is not ON (step S61: No), the CPU 441 moves the process to step S63.

In step S63, the CPU 441 determines whether it is 0.1 seconds before the stop time, that is, 59.9 seconds from the start of timing in this embodiment. If it is determined that it is not 0.1 second before the stop time (step S63: No), the CPU 441 returns the process to step S63 again. On the other hand, when determining that it is 0.1 second before the stop time (step S63: Yes), the CPU 441 moves the process to step S64.

In step S64, the CPU 441 performs processing to stop the voltage application signal sent to the polarity switching circuit 445 and stop energization.

Next, the CPU 441 determines whether it is a stop time (step S65). If it is determined that the stop time is not reached (step S65: No), the CPU 441 returns the process to step S65 again. On the other hand, when determining that it is the stop time (step S65: Yes), the CPU 441 moves the process to step S66.

In step S66, the CPU 441 stops the anode signal sent to the polarity switching circuit 445 and the pump part operation signal sent to the pump part 20.

Next, the CPU 441 writes the type of anode signal transmitted to the predetermined address of the EEPROM 444, the value of the electrode switching counter, the value of the interruption flag, etc. (step S67), and returns the processing to the address before branching.

Next, the operation of the hydrogen water generator 400 having the above-described configuration will be described with reference to FIGS. FIG. 27 is a timing chart showing states of various signals transmitted from the operation switch 15 and the control unit 440 (CPU 441) of the hydrogen water generating apparatus 400, and FIG. 28 is an enlarged partial time shown in FIG. It is the timing chart shown.

As shown in FIG. 27, the hydrogen water generator 400 electrolyzes the water to be electrolyzed while performing various treatments for about 15 minutes (about 900 seconds) when the user presses the operation switch 15. To produce hydrogen.

Further, the hydrogen water generator 400 regards it as a pseudo operation clock signal on the basis of one cycle of the peeling cycle consisting of the operation state time (ON time) and the stop state time (OFF time) of the pump unit operation signal, Various processes are executed. For example, the polarity of each porous electrode plate (each conductor rod) is switched every 5 cycles of the peeling cycle, that is, about every 5 minutes, and the electrolytic treatment is automatically terminated after 15 cycles of the peeling cycle, ie, about 15 minutes. It is configured.

Next, the operation of the hydrogen water generator 400 will be described with reference to various signals for each major event.

The left enlarged view of FIG. 28 is a timing chart when the hydrogen water generator 400 is started, the middle enlarged view is a timing chart when the pump unit 20 is stopped, and the right enlarged view is a timing when the polarity switching operation is performed. A chart is shown.

As can be seen from the left enlarged view of FIG. 28, when the operation switch 15 is pressed by the user, the control unit 440 executes the initial pump driving process (step S13), so that the water flow is about 2 seconds prior to the electrolysis. Start generating.

Next, the control unit 440 emits the anode signal determined to be transmitted in the start-up process (step S12), here the first conductor rod anode signal together with the voltage application signal by executing the energization start process (step S14). Supply of electric power to each porous electrode plate having the conductor rod 34 as an anode and the second conductor rod 35 as a cathode is started. Moreover, the time measurement by step S15 is started.

Next, as shown in the middle enlarged view of FIG. 28, when the control unit 440 determines that the operation state time (58 seconds) has elapsed since the start of time measurement (step S19: Yes), the pump stop process (step S41). ) To stop sending the pump unit operation signal and stop the operation of the pump unit 20.

After this stop state continues for about 2 seconds, the control unit 440 executes the pump driving process (step S15), thereby bringing the pump unit 20 into an operating state again.

Here, at the timing of restart of the pump unit 20 indicated by the black arrow in the figure, the bubbles that are difficult to peel off are peeled off from the surface of the porous electrode plate. In other words, the control unit 440 performs the process of stopping and restarting the operating pump unit 20 as described above, thereby separating the difficult-to-separate bubbles releasing means (for releasing the difficult-to-separate bubbles generated on the porous electrode plate). It will function as a difficult-to-peel bubble free part).

Next, referring to the right enlarged view of FIG. 28 about about 300 seconds shown in FIG. 27, the operation state time (58 seconds: 240 cycles corresponding to four cycles of the peeling cycle in this case) after starting the time measurement in step S15. If it is determined that (second + 58 seconds = 298 seconds) has elapsed (step S19: Yes), the pump stop process (step S41) is executed to stop the transmission of the pump unit operation signal, and the pump unit 20 is stopped.

Here, since the value of the electrode switching counter stored in the RAM 443 is “5” by the execution of step S20, the polarity inversion flag is turned ON in the pump stop process (step S44), and the peeling in the sixth cycle is performed. After entering the cycle and the pump unit 20 is in an operating state in step S15, the polarity inversion process (step S17) is performed. That is, the polarity inversion process is configured to be performed while the pump unit 20 is in operation.

Therefore, it is possible to avoid a temporary short circuit state between the porous electrode plates at the time of polarity switching due to the fact that the already electrolyzed water existing between the porous electrode plates has a capacity. It is possible to maintain an electric circuit that performs switching or the like.

In addition, the polarity inversion process is configured to be executed after waiting for the water flow stabilization time (0.5 seconds) and the water flow replacement time (0.5 seconds) after the pump unit 20 is restarted. Can be avoided more steadily.

Similarly, of the pair of short walls, the short wall near the opening 425 is referred to as a proximal short wall 531n, and the distant short wall is referred to as a distal short wall 531f.

The L-shaped water flow restricting plate 511 has a first water flow restricting plate 515 arranged to extend on the auxiliary line y1 over the length P1, and a first water flow restricting plate 515 extending in an L shape from the end of the first water flow restricting plate 515. 5 water flow restricting plate 516.

The first water flow restricting plate 515 is a member for regulating the flow while restricting the water flow in the vicinity of the opening 425, and a position intersecting the auxiliary line x2 in the short direction crossing the opening 425, for example, the first The water flow restriction plate 515 is erected so that the midpoint in the extending direction is located on the auxiliary line x2 or in the vicinity thereof. Further, the length P1 is configured such that P / 3 <P1 ≦ P / 4.5, more preferably substantially P / 4, with respect to the length P in the longitudinal direction of the electrolysis portion housing recess 424.

The fifth water flow restricting plate 516 is a water flow restricting plate extending in an L shape from the end on the distal short wall 531f side to the distal long wall 530f of both ends of the first water flow restricting plate 515. There is a role of regulating the flow from the proximal short wall 531n to the distal long wall 530f discharged from the opening 425. In the present embodiment, the fifth water flow restriction plate 516 is configured such that one end is connected to the first water flow restriction plate 515 and the other end is connected to the distal longitudinal wall 530f. Some clearance may be provided between them and the distal longitudinal wall 530f. That is, in a region surrounded by the first water flow restricting plate 515, the fifth water flow restricting plate 516, the distal long wall 530f, and the proximal short wall 531n (hereinafter referred to as a third vortex forming region). The gap may be formed as long as the vortex can be formed.

The second water flow restricting plate 512 is the auxiliary closest to the proximal longitudinal wall 530n among the auxiliary lines y2, auxiliary lines y1, and auxiliary lines y3 that substantially divide the length M in the short direction of the electrolysis part accommodating recess 424. It is a water flow regulating plate arranged on the line y2 so as to extend over the length P2. The length P2 is configured to satisfy P / 3 <P2 ≦ P / 4.5, more preferably substantially P / 4, with respect to the length P in the longitudinal direction of the electrolysis portion housing recess 424.

The third water flow restriction plate 513 is a water flow restriction plate arranged so as to extend over the length P3 on the auxiliary line y3 closest to the distal long wall 530f, similarly to the second water flow restriction plate 512. The length P3 is configured to satisfy P / 3 <P3 ≦ P / 4.5, more preferably substantially P / 4, with respect to the length P in the longitudinal direction of the electrolysis portion housing recess 424.

Each of the second water flow restriction plate 512 and the third water flow restriction plate 513 is a member for adjusting the water flow in the substantially central portion of the electrolysis portion housing recess 424, and is a position intersecting the auxiliary line x1, for example, the second water flow restriction plate. The middle point in the extending direction of the plate 512 and the third water flow regulating plate 513 is arranged on the auxiliary line x1 or in the vicinity thereof.

The fourth water flow restriction plate 514 is a water flow restriction plate for regulating the flow while restricting the water flow far from the opening 425, and is arranged to extend on the auxiliary line y1 over the length P4. The length P4 is configured to satisfy P / 3 <P4 ≦ P / 4.5, more preferably approximately P / 4, with respect to the length P in the longitudinal direction of the electrolysis portion housing recess 424.

The fourth water flow restriction plate 514 intersects with the auxiliary line x3 closest to the distal short wall 531f when the length P in the longitudinal direction of the electrolysis part accommodating recess 424 is divided into four, for example, the fourth water flow restriction plate 514. The plate 514 is arranged such that the midpoint in the extending direction is located on the auxiliary line x3 or in the vicinity thereof.

In addition, the first water flow restriction plate 515, the second water flow restriction plate 512, the third water flow restriction plate 513, and the fourth water flow restriction plate 514 are arranged at predetermined intervals in the longitudinal direction.

Specifically, the first water flow restriction plate 515 is disposed with a gap d1 between the proximal short wall 531n and the second water flow restriction plate 512 is disposed between the first water flow restriction plate 515 and the first water flow restriction plate 515. The third water flow restricting plate 513 is disposed with a sense d2b between the first water flow restricting plate 515 and the fourth water flow restricting plate 514 includes the second water flow restricting plate 512 and the first water flow restricting plate 512. A space d3a and a space d3b are opened between the three water flow restricting plates 513 and a space d4 is placed between the water flow restricting plate 513 and the distal short wall 531f.

These intervals d1 to d4 are not particularly limited as long as they are shorter than the lengths P1 to P4. In addition, the length P in the longitudinal direction of the above-described electrolytic unit housing recess 424 is P = d1 + P1 + d2a + P2 + d3a + P4 + d4 (P = d1 + P1 + d2b + P3 + d3b + P4 + d4).

The heights of the first water flow restricting plate 515, the second water flow restricting plate 512, the third water flow restricting plate 513, the fourth water flow restricting plate 514, and the fifth water flow restricting plate 516 provided on the bottom surface 510 will be described later. The distance between the bottom electrode 510 and the porous electrode plate (in this embodiment, the porous electrode plate 33-2) constituting the lowermost layer of the laminated electrode body 426 is not particularly limited as long as the vortex can be formed. That is, it can be 0.5 to 1 times the height of the pressure chamber 13b.

On the other hand, as shown in FIG. 29, among the porous electrode plates 31 to 33-2 constituting the laminated electrode body 426, the lowermost porous electrode plate 33-2 has a bubble flow at a position facing the opening 425. A non-porous region 517 (indicated by a broken line in the figure) where the hole 431 is not formed is formed.

In particular, in this modification, the bubble circulation holes 431 are regularly formed by performing a staggered punching process on a platinum-plated titanium substrate, more specifically, a 45 ° staggered or 60 ° staggered punching process. A non-porous region 517 is formed by attaching a closing piece 518 that closes the bubble circulation hole 431 to the bubble circulation hole 431 facing the opening 425. The non-porous region 517 is not limited to being formed by closing the formed bubble flow hole 431, and the non-porous region is not formed by forming the bubble flow hole 431 at a position facing the opening 425. 517 may be formed.

Further, in the porous electrode plate 32 and the porous electrode plate 33-1 in this modification, a part of the bubble circulation holes 431 among the bubble circulation holes 431 regularly formed in a zigzag manner are connected to the same bubble circulation hole 431. A closing piece 518 for closing is attached and arranged.

As described above, the hydrogen water generating apparatus according to the present modification has the following features (1) and (2) if briefly described.
(1) A point in which a non-porous region 517 is formed at a position facing the opening 425 in the lowermost porous electrode plate. (2) Longitudinal direction and short-side direction of the bottom surface 510 of the electrolytic portion accommodating recess 424 having a substantially rectangular shape in plan view. The opening 425 is formed at a position biased to the bottom, and the lower space (pressure chamber) formed between the bottom surface 510 and the electrolysis part 30 attached to the electrolysis part accommodating recess 424 is erected from the bottom surface 510. First to fourth water flow restricting plates extending in the longitudinal direction at a length of about 1/3 to 1 / 4.5 of the longitudinal direction are provided, and the first water flow restricting plate 515 is a short direction crossing the opening 425 The second water flow restricting plate 512 and the third water flow restricting plate 513 are disposed at approximately 1/4 and approximately 3/4 of the quarter direction, and the fourth water flow restricting plate 514 It is located at the approximate center in the short direction and the first water flow guide From end or end portion of the plate 515, that the fifth flow regulation plate 516 up to the distal longitudinal wall 530f or near a distant longitudinal wall from the opening portion 425 is erected into a substantially L-shaped

In the hydrogen water generating apparatus according to this modification, the configuration (1) is provided, so that the horizontal direction (space) in the space formed between the porous electrode plate 33-1 and the porous electrode plate 33-2 is provided. The velocity vector of the water flow in the direction of the spread of the water can be made almost uniform.

That is, in the case where the non-porous region 517 is not provided and the bubble circulation hole 431 is formed at a position facing the opening 425 on the porous electrode plate 33-2, the water flow discharged from the opening 425 to the pressure chamber 13b. Enters the space formed between the porous electrode plate 33-1 and the porous electrode plate 33-2 through the bubble circulation hole 431 as it is, collides with the porous electrode plate 33-1 and spreads in the horizontal direction. Therefore, the flow is biased.

On the other hand, by providing the non-porous region 517 as in this modification, the water discharged from the opening 425 flows directly into the space formed between the porous electrode plate 33-1 and the porous electrode plate 33-2. In addition to preventing this, the flow can be temporarily buffered in the pressure chamber 13b, and the deviation of the flow in the space formed between the porous electrode plate 33-1 and the porous electrode plate 33-2 can be suppressed, The velocity vector of the water flow in the same space can be made almost uniform.

Moreover, in the hydrogen water generating apparatus according to this modification, the configuration (2) is provided, so that a vortex can be actively formed in the pressure chamber 13b, and the water flow toward the laminated electrode body 426 can be made uniform. Can be planned.

Here, the formation of the vortex will be described with reference to FIG. 30 (b). First, the water flow F 3 out of the water discharged from the opening 425 is diverted by the first water flow restricting plate 515, and the distal short side from the opening 425. The water flow F1 is directed toward the wall 531f, and the water flow F2 is directed toward the proximal short wall 531n.

The water flow F1 is divided by the second water flow restriction plate 512 and the third water flow restriction plate 513, and the water flow F1a flowing between the proximal longitudinal wall 530n and the second water flow restriction plate 512, or the second water flow restriction plate 512 and the first water flow restriction plate 512. The flow is divided into a water flow F1b flowing between the three water flow restriction plates 513 and a water flow F1c flowing between the third water flow restriction plate 513 and the distal longitudinal wall 530f.

Further, the water flow F1b is caused by the fourth water flow by the fourth water flow restriction plate 514 and the water flow F1b1 toward the region between the fourth water flow restriction plate 514 and the proximal longitudinal wall 530n (hereinafter referred to as a first vortex formation region). The flow is further divided into a water flow F1b2 directed to a region between the restricting plate 514 and the distal longitudinal wall 530f (hereinafter referred to as a second vortex forming region).

In the first vortex formation region, the water flow F1a and the water flow F1b1 merge and collide to form a turbulent flow, thereby forming a vortex.

Also, in the second vortex formation region, a turbulent flow is formed by the water flow F1b2 and the water flow F1c joining and colliding with each other, and a vortex is also formed here. Note that the vortex shown in FIG. 30B merely schematically shows that the vortex is formed, and the size, number, shape, and winding direction are not necessarily accurate.

Also, when the water flow F2 hits the proximal short wall 531n, the water flow F2 flows along the proximal short wall 531n toward the distal long wall 530f, and then starts flowing along the distal long wall 530f.

The water flow F2 that has started to flow toward the distal short wall 531f along the distal long wall 530f collides with the fifth water flow restriction plate 516. That is, the water flow F2 along the distal longitudinal wall 530f is divided by the fifth water flow restriction plate 516, changes its direction in the direction along the fifth water flow restriction plate 516, and becomes a water flow along the first water flow restriction plate 515. In the third vortex formation region, a complex flow is formed in combination with the newly flowing water flow F2 to form a vortex.

As described above, in the hydrogen water generating apparatus according to the present modification, each water flow regulating plate is used as a rectifying means (rectifying part), a dividing means (compartment part), a diverting means (dividing part), and a vortex forming means (vortex forming part). By functioning, a plurality of vortices are positively formed by the presence of each water flow regulating plate in the pressure chamber 13b, and the water flow toward the laminated electrode body 426 is made uniform.

Then, according to the hydrogen water generating apparatus having the above-described configuration, even when the opening 425 is provided at a position on the bottom surface 510 that is biased in the longitudinal direction and the lateral direction, it is substantially uniform from the top of the electrolysis unit 30. A water stream containing hydrogen bubbles can be released.

Further, in the case where a water flow containing hydrogen bubbles that can be visually recognized by the user is released, by providing such a configuration, compared with the case where the visible hydrogen bubbles are released in a biased state. Therefore, it is possible to give the user an idea that hydrogen diffuses evenly in the bathtub, and it is possible to promote the redox effect caused by hydrogen bubbles and hydrogen water from the psychological viewpoint.

(5) Summary:
According to each embodiment described above, the case 10 having the water passage 313 that can be immersed in water and that allows the water inlet 11 and the water outlet 12 to communicate with each other, and the case 10 are accommodated in the water passage 313. A pump unit 20 that generates water, an electrolysis unit 30 disposed in the water passage 313, and a power supply unit 40 that is accommodated in the case 10 and supplies power to the pump unit 20 and the electrolysis unit 30. A plurality of porous electrode plates 31 to 33 arranged at regular intervals are provided, and the pump unit 20 realizes a hydrogen water generating device that generates a water flow toward the plate surfaces of the porous electrode plates 31 to 33. Can do.

The hydrogen water generating apparatus configured as described above is immersed in water, and a water flow is generated in the water passage 313 between the inlet 11 and the outlet 12 of the case 10 by the pump unit 20, and the hydrogen water generator is disposed in the water passage 313. The water flowing through the water passage 313 is electrolyzed by the electrolytic unit 30. At this time, the pump unit 20 generates a water flow toward the plate surfaces of the porous electrode plates 31 to 33 that are arranged at regular intervals that constitute the electrolysis unit 30. Thus, by applying the pressure of the water flow to the plate surfaces of the porous electrode plates 31 to 33, the hydrogen or oxygen bubbles generated by the electrolysis on the surfaces of the porous electrode plates 31 to 33 are pushed away at the moment of electrolysis. The hydrogen bubbles contained in the water flowing out from the outlet of the hydrogen water generator can be microbubbled or dissolved in molecular level hydrogen, nanobubbles or microbubbles.

In addition, the porous electrode plates 231 to 233 have a polygonal cross-section in which the partition wires W that partition the bubble flow holes of the porous electrode plates 231 to 233 have corners that are sharpened toward the water flow generated by the pump unit 20. It has become.

In the hydrogen water generating apparatus configured as described above, an inclined surface through which the partition wire W receives the water flow generated by the pump unit 20 toward the bubble circulation holes on both sides between the bubble circulation holes of the porous electrode plates 231 to 233. Therefore, the defoaming property on the surfaces of the porous electrode plates 231 to 233 is improved. In addition, since the surface between the bubble circulation holes of the porous electrode plates 231 to 233 is configured as a separate surface across the corner, the bubbles generated on one surface do not merge with the bubbles generated on the other surface. Further, bubbles released from the porous electrode plates 231 to 233 are expected to become finer, and hydrogen can be dissolved in a molecular level hydrogen, nanobubble or microbubble state. Further, since the porous electrode plates 231 to 233 between the bubble circulation holes have corners directed toward the water flow, the water flow flowing through the bubble circulation holes of the porous electrode plates 231 to 233 becomes smooth and is farthest from the pump unit 20. The water flow can be maintained until the bubble circulation holes of the porous electrode plates 231 to 233 are circulated. In addition, since the corner portion has a small surface tension, the bubble releasing property of the bubbles generated at the corner portion between the bubble circulation holes of the porous electrode plates 231 to 233 that the water flow directly hits is improved.

In addition, the bubble circulation holes 31a to 33a of the plurality of porous electrode plates 31 to 33 are provided in a substantially staggered positional relationship between adjacent porous electrode plates.

In the hydrogen water generating apparatus configured as described above, the positions of the bubble circulation holes 31a to 33a formed in the plurality of porous electrode plates 31 to 33 are alternately formed. The flowing water flow will flow along the porous electrode plate to every corner between the porous electrode plates, improving the foam releasing property on the entire surface of the porous electrode plate, and improving the water replacement efficiency between the multiple porous electrode plates. Can do.
