Description

The present invention relates to a folded electrode, a parallel electrode plate structure using the folded electrode, and a laminated electrode pair.

Conventionally, electrolyzed water that electrolyzes water to produce electrolyzed water for various purposes such as containing hydrogen or oxygen in water or adjusting the liquidity of water to be used for various purposes such as drinking, bathing, and external skin Generators are known.

Examples of such electrolyzed water generators include a water conditioner that discharges electrolyzed water or a shower, a device that dissipates electrolyzed water by immersing it in water such as bath water, and a pot or water bottle-shaped device. These devices have a built-in electrode pair (hereinafter also referred to as an electrolytic electrode pair) for contacting water for electrolysis.

An electrolytic electrode pair is in principle usable if it has a pair of positive and negative electrodes arranged at appropriate intervals, but in order to improve the electrolysis efficiency and the amount of electrolyzed water produced, a plurality of flat plate-shaped electrodes are used. There has been proposed an electrolytic electrode pair (hereinafter, also referred to as a laminated electrode pair) in which the electrode plates of (1) are superposed at regular intervals.

This laminated electrode pair increases the electrolysis area and generates electrolysis efficiency and electrolyzed water by making the electrode plates that are superposed on each other alternately have relatively different potentials such as "positive/negative/positive/negative". It is possible to improve the amount.

Further, in order to form the laminated electrode pair, it is necessary to electrically connect the electrode plates that have the same potential to every other electrode plate, but in order to realize this, a plurality of electrode plate parts form a bridge part. An electrode (hereinafter, referred to as a folded electrode) is constructed by bending an electrode plate connected body composed of one metal flat plate connected through the bending plate at the bridge part and folding the electrode plate part so that the electrode plate parts overlap each other. A laminated electrode pair is known in which an electrolytic electrode pair is configured by combining the folding electrodes as a positive and negative pair (see, for example, Patent Document 1).

According to such a laminated electrode pair that adopts the folded electrode, since the electrode plates having the same potential are electrically connected in advance at the bridge portion, it is possible to compare with the laminated electrode pair in which each electrode plate is separated. Then, the assembly of the electrolytic electrode pair is easy.

Utility model registration No. 3207066

By the way, as described above, the electrolytic electrode pair is adopted in various electrolyzed water producing apparatuses, but in the case of a relatively small apparatus such as a shower, it is desirable that the electrolytic electrode pair is also smaller. In addition, it is desired to reduce the size and weight of each of the other devices.

In this respect, the laminated electrode pair that is easy to secure the electrolysis area is relatively advantageous, but in the case of the laminated electrode pair that adopts the conventional folding electrode, the overlapping electrode plates do not interfere with each other so that a short circuit or the like does not occur. It is necessary to fold the connection base of each bridge part of the folding electrode at a right angle with high accuracy.

Further, it is advantageous in terms of electrolysis efficiency that the gap between the electrode plates of the laminated electrode pair is narrow, but the narrower the gap, the higher the accuracy required for forming the connecting base of the bridge portion at right angles, and this bending operation is It is necessary to perform the treatment at two right angles for each cross-linking portion, and since it is performed for every cross-linking portion, it is considerably complicated in manufacturing.

The present invention has been made in view of such circumstances, and provides a folding electrode capable of further simplifying the bending work at the bridge portion of the electrode plate connected body.

Further, the present invention also provides a parallel electrode plate structure in which the same folding electrodes are used and the respective electrode plate portions are parallel to each other, and a laminated electrode pair adopting the folding electrodes or the parallel electrode plate structure.

In order to solve the above-mentioned conventional problems, in the folding electrode according to the present invention, (1) a plurality of electrode plate parts is composed of an electrode plate connected body composed of one metal flat plate connected through a bridge part, The electrode plates are overlapped with each other with a gap due to the substantially semi-circular bending structure formed in the portion.

The folding electrode according to the present invention is also characterized by the following points.
(2) In the free state, the folding electrode is formed so that the gap between the opposing electrode plate portions gradually narrows as it is separated from the bridge portion connecting the both electrode plate portions.
(3) In the free state, the folding electrode is formed so that the gap between the opposing electrode plate portions gradually expands as the distance from the bridge portion connecting the both electrode plate portions increases.

The parallel electrode plate structure according to the present invention is a parallel electrode plate structure in which the electrode plate portions of the folding electrodes of (4) and (2) are arranged substantially parallel to each other, and inside the facing electrode plate portions. A spacer was interposed in the gap and each electrode plate portion was biased in the expanding direction and arranged substantially in parallel.

The parallel electrode plate structure according to the present invention is a parallel electrode plate structure in which the electrode plate portions of the folding electrodes described in (5) and (3) are arranged substantially parallel to each other, and the electrode plate portions facing each other are provided. It is also characterized in that a holder is arranged on the outer side of each of the electrodes and is urged in a direction of narrowing each electrode plate portion and arranged substantially in parallel.

Further, in the laminated electrode pair according to the present invention, the folding electrode according to (6) and (1) has a bending structure in which each electrode plate portion is substantially parallel to each other, and an electrode plate portion of the folding electrode. And an intervening electrode plate disposed in the gap and applied with a relatively opposite potential.

In addition, in the laminated electrode pair according to the present invention, as another aspect, a folding electrode in which the electrode plate portions are arranged substantially in parallel by the parallel electrode plate structure described in (7), (4) or (5), And an intervening electrode plate which is arranged in the gap between the electrode plates of the folding electrode and which is applied with a relatively opposite potential.

The laminated electrode pair according to the present invention is also characterized by the following points.
(8) The end portion of the interposed electrode plate is arranged closer to the bridge portion than the center of curvature of the bending structure in the bridge portion of the folding electrode.
(9) The interposed electrode plate is an electrode plate portion of the second folding electrode.

According to the folding electrode of the present invention, a plurality of electrode plate portions is composed of an electrode plate connected body composed of one metal flat plate that is continuous via a bridge portion, and a substantially semi-circular bending structure formed in the bridge portion. Since the electrode plate portions are overlapped with each other with a gap therebetween, the bending work at the bridge portion of the electrode plate connected body can be further simplified.

In the free state, the folding electrodes may be formed such that the gaps between the electrode plate portions facing each other are gradually narrowed as they are separated from the bridging portion connecting the two electrode plate portions. It is not always necessary to perform such bending work, and the bending work can be simplified, and when the electrode plate parts are arranged substantially parallel to each other, the electrode plate parts are urged in the expanding direction. Therefore, it is possible to firmly maintain the parallel state of each electrode plate by utilizing the restoring force for returning from the biased parallel state to the constricted free state.

In addition, when the folding electrodes are formed so that, in a free state, the gaps between the opposing electrode plate portions gradually expand as they are separated from the bridging portion connecting both electrode plate portions, the electrode plate portions are accurately parallel to each other. It is not always necessary to perform such bending work, and the bending work can be simplified, and when the electrode plate parts are arranged substantially parallel to each other, the electrode plate parts are urged in a direction to narrow them. Therefore, it is possible to steadily maintain the parallel state of each electrode plate by utilizing the restoring force for returning from the biased parallel state to the free state where the electrode plate expands.

Further, according to the parallel electrode plate structure of the present invention, the parallel electrode plate structure is formed by arranging the electrode plate parts of the folding electrode of (2) described above in substantially parallel to each other. Since each electrode plate part is urged in the expansion direction and arranged substantially parallel to each other with a spacer interposed in the inner gap, the parallel state of each electrode plate can be made steady by utilizing the urging force of each electrode plate part in the expansion direction. Can be maintained at.

Further, in the parallel electrode plate structure in which the electrode plate portions of the folding electrode of (3) described above are arranged substantially parallel to each other, a holding body is arranged outside the facing electrode plate portions and each electrode plate portion is By urging the electrode plates in the narrowing direction and arranging them in parallel, it is possible to firmly maintain the parallel state of the electrode plates by utilizing the urging force of the electrode plate portions in the narrowing direction.

Further, according to the laminated electrode pair of the present invention, the folding electrode of the above-mentioned (1), which has a bending structure in which the electrode plate portions are substantially parallel to each other, or the above-mentioned (4) or (5). With the parallel electrode plate structure, the folded electrodes in which the electrode plate portions are arranged substantially parallel to each other, and the intervening electrode plate which is arranged in the gap between the electrode plate portions of the folded electrode and which is applied with a relatively opposite potential, Since it is provided, it is possible to provide a laminated electrode pair which can be easily constructed by simplifying the folding work of the folding electrode.

Further, if the end portion of the interposed electrode plate is arranged closer to the bridge portion than the center of curvature of the bending structure in the bridge portion of the folded electrode, the interposed electrode near the end portion of the interposed electrode plate is disposed. It is possible to suppress as much as possible the uneven wear of the plate itself, the opposing electrode plate portion, and the bridge portion due to the electrolysis.

Further, if the interposed electrode plate is the electrode plate portion of the second folding electrode, it becomes a folding electrode for both the positive and negative electrodes, and it is possible to mutually suppress uneven wear due to electrolysis.

The present invention comprises an electrode plate connected body composed of one metal flat plate in which a plurality of electrode plate parts are connected through a bridging part, and the electrode plate parts are mutually separated by a bending structure formed in the bridging part. The present invention provides a folding electrode which can simplify the bending work at the bridge portion of the electrode plate connected body with respect to the overlapping folding electrodes.

Further, the present invention also provides a parallel electrode plate structure in which the same folding electrodes are used and the respective electrode plate portions are parallel to each other, and a laminated electrode pair adopting the folding electrodes or the parallel electrode plate structure.

Hereinafter, the folding electrode, the parallel electrode plate structure, and the laminated electrode pair according to the present embodiment will be described in detail with reference to the drawings.

FIG. 1 is an explanatory diagram showing the appearance of a laminated electrode pair B1 that employs the folded electrode A1 according to this embodiment. As shown in FIG. 1, the laminated electrode pair B1 includes an electrode laminated portion 10 and two conducting rods 11a and 11b extended from the electrode laminated portion 10, and each conducting rod 11a, 11b has By applying voltages of relatively different potentials to each other, it is possible to electrolyze water in contact with the electrode laminated portion 10.

The electrode laminated portion 10 is composed of a folded electrode A1 and an interposed electrode plate 12 interposed in the gap of the folded electrode A1, and a plurality of sheets (three in the laminated electrode pair B1 according to the present embodiment). The plate-like electrode plates have a structure in which they overlap with each other while forming a constant gap. In particular, in this embodiment, the gap between the electrodes of the electrode laminated portion 10 is set to 0.3 to 1.0 mm, which constitutes a narrow electrode body excellent in electrolysis efficiency.

As shown in FIG. 2A, the interposed electrode plate 12 is a metal plate body having substantially the same shape (generally rectangular shape in plan view) as the electrode plate portion 14 of the folding electrode A1 described later, and serves as a counter electrode of the folding electrode A1. It works. Although it is an arbitrary configuration, a plurality of elongated holes 12a are formed in the interposed electrode plate 12 so that water can be easily introduced between the electrode plates. Further, a conductive rod 11b is connected to the interposed electrode plate 12 as shown by a broken line.

On the other hand, the folding electrode A1 shown in FIG. 1 is formed by bending the electrode plate connected body 13 shown in FIG. 2B. The electrode plate connected body 13 is obtained by punching or the like from a single metal flat plate, and includes a plurality of (two in the present embodiment) electrode plate portions 14 and a bridge that electrically connects each electrode plate portion 14. The folding electrode A1 is formed by bending the cross-linking portion 15 indicated by the alternate long and short dash line along a line that crosses the cross-linking portions 15.

The electrode plate portion 14 is a counter electrode of the interposed electrode plate 12 and functions as an electrode plate that exhibits the electrolytic function of the folding electrode A1. In the folding electrode A1 according to the present embodiment, which has an arbitrary configuration, a plurality of elongated holes extending in the electrode plate portion 14 in the connecting direction of the electrode plate portion 14 (vertical direction in FIG. 2A) are also provided. The holes 14a are formed so that water can be easily introduced between the electrode plates.

Further, a conducting rod 11a is connected to the electrode plate portion 14 as shown by a broken line, and a current can be supplied to the folding electrode A1 at a predetermined voltage. The conducting rod 11a may be attached to the electrode plate portion 14 before folding the electrode plate connecting body 13, or may be attached after folding.

The bridge portion 15 is a portion for electrically connecting the electrode plate portions 14 and forming an integral structure. In particular, as a characteristic of the folding electrode A1 according to the present embodiment, as shown in FIG. 1, the bending structure formed in the bridging portion 15 has a substantially semi-arcuate shape. The number of the bridging portions 15 is not particularly limited and may be a single number, but a plurality of bridging portions 15 may be provided as shown in FIG. 2(b). When a plurality of cross-linking portions 15 are provided, the electrode plate connected body 13 is bent, and when the folded electrode, the parallel electrode plate structure, and the laminated electrode pair are formed, it is easy to ensure the parallelism between the electrode plates with high accuracy, Further, the structural strength can be increased, which is preferable.

FIG. 3 is an explanatory diagram schematically showing a cross section taken along line P1-P1 of the laminated electrode pair B1 of FIG. Note that the distance, thickness, positional relationship, detailed configuration, and the like between the folding electrode A1 and the interposed electrode plate 12 may be partially omitted or exaggerated for convenience of explanation, and the same applies to other drawings. .. When forming the folding electrode A1, the bridging portion 15 is folded along the folding line shown in the electrode plate connected body 13 in FIG. 2B, and at this time, as shown in FIG. A substantially semi-circular bending structure is formed in the portion 15.

With such a structure, the folding work can be made extremely simple without the complicated work of bending the two roots of the bridge portion at a right angle with high precision like the conventional folding electrode. You can The bending structure can be formed by pressing as well as bending. Further, the bending structure is typically a natural bending structure formed by bending, and therefore the bending structure does not need to have an exactly semi-arcuate shape. The electrode plate portion 14 and the interposed electrode plate 12 of the folded electrode A1 may have a plate thickness of, for example, 0.1 mm to 1.0 mm, more preferably 0.2 mm to 0.5 mm. It is possible to use a titanium plate or the like plated with.

The semi-arcuate bending structure of the folding electrode A1 is, for example, as shown in the left diagram of FIG. 4, a bending structure in which the electrode plate portions are substantially parallel to each other in the free state (hereinafter also referred to as a parallel bending structure). It may be a stronger bend, that is, a sharp bend. In the following description, such a bent structure that is sharper than the parallel bent structure is also referred to as an overhang structure for convenience.

When such an overhang structure is allowed at the time of forming the bending structure, it is not always necessary to perform the work of forming the bridging portion 15 so that the electrode plate portions 14 are exactly parallel to each other, and the bending work is further performed. It can be simplified.

In constructing the parallel electrode plate structure in which the electrode plate portions 14 of the folding electrode A1 having the overhang structure are arranged substantially parallel to each other, as shown in the right diagram of FIG. The electrode plates 14 may be kept parallel to each other by interposing the spacer 16 in the inner space of the electrode.

For example, if a specific example is given, the spacer 16 is installed by forming a fitting hole 17 for the spacer 16 in the interposer electrode plate 12 as shown in FIG. Alternatively, the spacer 16 may be formed so as to maintain a space between the interposing electrode plate 12 and the electrode plate portions 14 arranged on the front and back sides by fitting the spacers 16 in a protruding state and locking the spacers 16 with the locking claws 16a. it can.

With such a configuration, when the electrode plate portions 14 are arranged substantially parallel to each other, the electrode plate portions 14 can be urged in the expanding direction, and this urging force, that is, the force to restore. Can be used to reliably maintain the parallel state of each electrode plate.

Similarly, this bending structure can be weaker in the free state than the parallel bending structure shown in the left diagram of FIG. 6, that is, a gentle bending. In the following description, such a bent structure that is bent more gently than the parallel bent structure is also referred to as an underhang structure for convenience.

Also in the case of forming this underhang structure, as in the case of forming the overhang structure described above, in constructing the parallel electrode plate structure, it is not always necessary to perform a bending work such that the electrode plate portions are accurately parallel to each other. Therefore, the bending work can be simplified.

In constructing the parallel electrode plate structure in which the electrode plate portions 14 of the folding electrode A1 having the underhang structure are arranged substantially parallel to each other, as shown in the right diagram of FIG. It is also possible to arrange the holding bodies 18 on the outside of the above so as to keep the electrode plate portions 14 parallel to each other.

With such a configuration, when the electrode plate portions 14 are arranged substantially parallel to each other, the electrode plate portions 14 can be urged in a direction of narrowing the electrode plate portions 14, and this urging force, that is, the force to restore the force. By utilizing this, the parallel state of each electrode plate can be maintained steadily. Even in the parallel electrode plate structure of the folding electrode A1 having the underhang structure, the spacer 16 may be interposed between the electrode plates as in the case of the overhang structure shown in the left diagram of FIG.

By the way, in the electrolyzed water generator, the efficiency of electrolysis is affected by the quality of water used. Water varies in hardness depending on the region, that is, the amount of mineral components such as calcium and magnesium dissolved in water. The electric conductivity (conductivity) of water varies depending on the hardness, and the conductivity increases with water having a high hardness, and the electrolysis voltage decreases accordingly. When the electrolysis voltage decreases, the generated gas is less likely to become microbubbles, and the efficiency with which the generated hydrogen is dissolved in water decreases.

Therefore, it is desirable to set the voltage higher in the electrolyzed water generator used in areas with high hardness, but to do so, it is necessary to make a costly and time-consuming major design change such as changing the circuit or changing the shape of the electrolytic electrode. Is.

Therefore, in order to deal with such a case without causing a significant design change, in the present embodiment, a blocking plate 23 as shown in the left diagram of FIG. 7 is provided between the electrode plate portion 14 and the interposed electrode plate 12. I also suggest that you attach it in between.

This blocking plate has a shape that can be placed between the electrode plates of the existing stacked electrode pair, and by inserting it, the electrode plates can be partially blocked and the electrode area can be effectively reduced. .. The electrolytic voltage can be adjusted by changing the area of the blocking plate, and an appropriate electrolytic voltage can be easily set according to the hardness.

The blocking plate is preferably made of a material having insulation and water resistance, and for example, polyethylene, polypropylene, polyethylene terephthalate, polycarbonate, PMMA resin, ABS resin, etc. are suitable.

For example, in the case of the present embodiment, the blocking plate 23 is attached to one surface of the interposing electrode plate 12, and the interposing electrode plate 12 on which the blocking plate 23 is attached is folded as shown in the right diagram of FIG. The laminated electrode pair B1 is constructed by being interposed between the plate portions 14.

In the laminated electrode pair B1 constructed in this way, as shown in FIG. 8(a), electrolysis is performed in the region where the blocking plate 23 is mounted in the gap between the electrode plate portion 14 and the interposed electrode plate 12. As a result, the electrolysis voltage can be increased by reducing the effective area of the electrodes, and it is possible to easily set an appropriate electrolysis voltage according to the hardness of water.

The blocking plate 23 is not necessarily provided at only one place, and can be applied to any portion between the interposed electrode plate 12 and the electrode plate portion 14, for example, as shown in FIG. As shown, blocking plates 23 can be mounted on both front and back sides of the interposed electrode plate 12 and can be appropriately adjusted so as to limit the electrolysis area according to the hardness of water.

Further, as described above, the present invention provides a laminated electrode pair constructed by using the folding electrode A1 and the interposed electrode plate 12, but the electrode plate portions 14 of the folding electrode A1 are originally parallel to each other. In some cases, or when the electrode plate portions 14 are originally arranged in a non-parallel state due to the overhang structure or the underhang structure but the electrode plate portions 14 are arranged substantially parallel to each other by the parallel electrode plate structure according to the present embodiment, the folding electrode Regarding the positional relationship between A1 and the interposed electrode plate 12, as shown in FIG. 9(a), the end portion 12b of the interposed electrode plate 12 is more than the center of curvature Q1 of the bending structure in the bridge portion 15 of the folding electrode A1. A laminated electrode pair may be arranged close to the bridge portion 15. For example, in the example of FIG. 9A, the end portion 12b of the interposed electrode plate 12 is arranged closer to the bridge portion 15 by a length d4 than the center of curvature Q1. In the following description, such a structure is also referred to as a bridge portion approaching structure at the end of the interposed electrode for convenience.

The lengths d2 and d3 from the end portion 12b to the facing surface of the bridge portion 15 are set to be about d1±20% of the length d1 of the electrode plate gap.

With such a configuration, it is possible to contribute to the electrolysis without waste even at the bridge portion 15 of the folding electrode A1, and at the same time, the interposed electrode plate 12 itself in the vicinity of the end of the interposed electrode plate 12 and the facing electrode plate 12 face each other. It is possible to suppress uneven wear of the electrode plate portion 14 and the bridge portion 15 due to electrolysis as much as possible.

Further, FIG. 9B is an explanatory diagram showing a more preferable example in the structure of approaching the bridge portion at the end of the interposed electrode. FIG. 9B shows the curvature center position Q1 of the end portion 12b of the interposed electrode plate 12 by the length d5, which is substantially the same as the bridge electrode approaching structure of the interposed electrode end shown in FIG. 9A. Although it is arranged closer to the bridge portion 15 than that, the configuration is different in that the shape of the end portion 12b is rounded.

With such a configuration, the length from the end 12b to the facing surface of the bridging portion 15 can be made substantially the same as the length d1 of the electrode plate gap, and the uneven wear can be further alleviated. it can.

Further, the description of the folding electrode so far has been developed mainly on the example of the folding electrode A1 constituted by the electrode plate connected body 13 provided with the two electrode plate portions 14 as shown in FIG. 2B. The number of electrode plate portions 14 is not particularly limited as long as it is plural.

For example, as shown in FIG. 10( a ), an electrode plate connected body 19 including three electrode plate portions 14 or an electrode plate connected body including a greater number of electrode plate portions 14 may be constructed. It is possible.

For example, the electrode plate connected body 19 shown in FIG. 10A is composed of one metal flat plate in which the three electrode plate portions 14 are connected to each other via the bridge portion 15, and an imaginary line L1 crossing the bridge portion 15 is formed. 10 (b) is formed by alternately forming a bending structure such as a mountain fold and a valley fold, or a valley fold and a mountain fold (indicated by a one-dot chain line) and L2 (indicated by a two-dot chain line). It is possible to construct the folding electrode A2 including the electrode plate portions 14 that are overlapped with each other.

Further, when the stacked electrode pair B2 is constructed by using the folded electrode A2, the interposed electrode plate 12 may be arranged in the gap between the folded electrodes A2 as shown by the broken line. At this time, it is needless to say that the laminated electrode pair B2 may have the above-mentioned overhang structure, underhang structure, and the structure in which the interposing electrode end crosses the bridge portion, and the above-mentioned parallel electrode plate structure may be adopted. it can.

Further, the intervening electrode plate interposed in the electrode plate portion 14 of the folding electrode does not necessarily have to be one electrode plate as shown in FIG. 2A, both are folding electrodes, and one is the other. It may also function as an intervening electrode plate.

That is, as shown in FIG. 11A, for example, a bending structure is formed in the bridge portion 15 of the electrode plate connected body 20 including the three electrode plate portions 14 to form the first folding electrode A3, and FIG. ), a bending structure is formed in the bridge portion 15 of the electrode plate connected body 21 including the two electrode plate portions 14 to form the second folding electrode A4, and the other folding electrode is interposed in the gap between the one folding electrode. By doing so, a laminated electrode pair B3 as shown in FIG. When interposing the folding electrode, the length K1 between the bridge portions 15 on one side (for example, the first folding electrode A3) is set to the one side (for example, the second folding electrode A4) on the most side. By setting the length K2 from the portion 15 to the other end portion to be larger than the length K2, the interposition work can be easily performed.

FIG. 12B is an explanatory diagram schematically showing the P2-P2 cross section of FIG. In the laminated electrode pair B3 configured in this way, both the first folding electrode A3 and the second folding electrode A4 have the same polarity, and the electrode plate portions 14 are electrically connected in advance by the bridging portion 15. Therefore, the work of constructing the laminated electrode pair can be dramatically facilitated.

Further, in this laminated electrode pair B3 as well, by providing the structure for approaching the bridge portion at the end of the interposed electrode, both positive and negative electrodes become folding electrodes, and it is possible to mutually suppress uneven wear due to electrolysis.

Furthermore, it goes without saying that the laminated electrode pair B3 may also have the above-mentioned overhang structure or underhang structure.

For example, when the laminated electrode pair B3 has an overhang structure, a parallel electrode plate structure can be formed by interposing a spacer member 22 between each electrode plate portion 14 as shown in FIG.

That is, a slit-shaped groove portion 22a is formed on one surface of the spacer member 22 having a substantially rectangular shape in appearance, and the predetermined electrode plate portion 14 is inserted into the groove portion 22a from the side surface portion of the laminated electrode pair B3. By doing so, the gap between the electrode plate portions 14 is steadily held by the urging force of the spacer member 22 in the expansion direction derived from the overhang structure, and the laminated electrode pair B3 is kept in an integrated state. You can

Next, an example of use of the laminated electrode pair adopting the folding electrode or the parallel electrode plate structure according to this embodiment described above will be described.

FIG. 15 shows an exploded view of the electrolytic hydrogen water shower head D2.

As shown in FIG. 15, the electrolytic hydrogen water shower head D2 includes a shower body 40 and a power storage unit 41. The shower body 40 includes a stem portion 42 and a head portion 43. Is composed of an outer cylinder body 44 and an electrolysis section 45.

The power storage unit 41 has a role of storing electric power for supplying energy required for electrolysis in the shower body 40. Specifically, a secondary battery is housed inside the power storage unit 41, and by mounting the secondary battery on the back surface 43 a of the head unit 43, electric power can be supplied to the electrolysis unit 45 of the shower body 40. ..
