Description

TECHNICAL FIELD The present invention relates to a water electrolysis device and an electrolyzed water discharge terminal.

2. Description of the Related Art Conventionally, there has been known a device for producing functional water by subjecting water to electrolysis (hereinafter, also referred to as a water electrolysis device).

When water is interposed between the cathode and anode electrodes having a predetermined potential difference arranged in the device and electricity is passed, for example, hydrogen is generated from the cathode. So-called hydrogen water is produced.

Hydrogen water has been reported to reduce in vivo oxidative stress and suppress the increase in blood LDL by drinking or bathing when the concentration of dissolved hydrogen gas is approximately 40ppb to 50ppb or more. Functionality such as contributing to health is expected (see, for example, Patent Document 1).

In addition, focusing on the anode side, since oxygen is generated from the electrode with the electrolysis of water, the water subjected to electrolysis contains more oxygen than the state before electrolysis, so-called It can be said that it is oxygen water, and it is possible to enjoy the functions of the contained oxygen gas.

Further, when a predetermined component, for example, a predetermined amount of sodium chloride is dissolved in water and electrolysis is performed, sodium hypochlorite is produced. Water containing sodium hypochlorite has a bleaching action and a sterilizing action, and is useful for cleaning and sanitation around water.

Thus, various functional waters (hereinafter also referred to as electrolyzed water) generated by water electrolyzers are expected to be used in various aspects of our lives.

The electrolysis unit, which can be said to be the heart of the water electrolysis device, requires a certain amount of electrode plate area in order to generate an appropriate amount of electrolyzed water for each purpose, and tends to occupy a relatively large volume ratio within the device. There is

Such a tendency does not pose a big problem for relatively large equipment that is used stationary. However, for devices that require miniaturization, an electrolytic section structure that can be compactly introduced into the device is required.

For example, portable devices that are assumed to be carried relatively frequently are often required to be downsized. At the same time, portable devices are often equipped with a power supply source independent of commercial power, such as a battery (secondary battery). Therefore, there is a demand for an electrolytic part structure that can efficiently electrolyze with a small amount of electric power.

However, if the electrode structure is simply reduced in size, the electrolyzed power will increase, and the flow resistance of water between the electrodes will increase, resulting in a significant reduction in the generation efficiency of electrolyzed water.

Furthermore, bubbles generated during electrolysis also pose a problem. Gases such as hydrogen and oxygen are generated from each electrode during electrolysis, and air bubbles adhere to the electrode surface. That is, the adhesion of air bubbles is equivalent to a reduction in the contact area between water and electrodes, which increases the power required for electrolysis, leading to a decrease in electrolysis efficiency. Simply reducing the size of the electrode portion relatively increases the volume of the bubbles, and the adhesion of the bubbles causes a decrease in electrolysis efficiency.

In view of such circumstances, the present invention provides a water electrolysis device and an electrolysis device that have high electrolysis efficiency and excellent electrolyzed water generation efficiency even in equipment that requires miniaturization and battery drive, such as a portable water electrolysis device. The purpose is to provide a water discharge terminal.

SUMMARY OF THE INVENTION The present invention provides a water electrolysis device and an electrolyzed water discharge terminal that have good electrolysis efficiency and are excellent in the generation efficiency of electrolyzed water.

Another aspect of the present invention is to provide a water electrolysis device and an electrolyzed water discharge terminal that have high electrolysis efficiency and excellent electrolyzed water production efficiency even when the device is compact and portable. It can be said that it does.

One of the important points for efficient electrolysis is "removal of air bubbles". When water is electrolyzed, oxygen is generated from the anode and hydrogen is generated from the cathode. Since these are gases, they exist as bubbles on the surface of the electrode plate when they are generated, and eventually leave the electrode plate and float in the water.

However, when there are air bubbles on the surface of the electrode plate, the surface portion of the electrode plate that is not in contact with water due to adhesion of gas does not contribute to electrolysis. This is equivalent to a relative decrease in the contact area between the electrode plate and water, which is the electrolyte, and the power required for electrolysis increases. Thus, the presence of air bubbles on the electrode plate causes a reduction in electrolysis efficiency. Therefore, it is preferable to remove the generated bubbles from the surface of the electrode plate as soon as possible for efficient electrolysis.

Here, the water electrolysis device broadly means a device that generates electrolyzed water, and its use is not particularly limited, including drinking and bathing.

For example, the electrolysis function is added to existing items, such as a shower in the bathroom with an electrolysis function and a water bottle with an electrolysis function. In addition to meaning things, existing products that are intended for electrolysis itself, such as devices that generate electrolyzed water by electrolysis in a state where it is submerged in pooled water such as bath water in a bathtub, and further unknown applications The concept also includes a generator for the electrolyzed water used.

Above all, the water electrolysis apparatus according to the present embodiment can be said to be extremely useful in terms of electrolysis efficiency and electrolyzed water generation efficiency when miniaturization is achieved as described above and when it is interpreted as a portable apparatus.

In order to facilitate the image of such a water electrolysis device, if we dare to give specific examples, for example, a shower head type water electrolysis device, a faucet attachment type water electrolysis device, a bath water input type water electrolysis device, and a water bottle. type water electrolysis apparatus, spray type water electrolysis apparatus, and the like.

A shower head type water electrolysis device is required to be small and light because it is used by hand, and it is desirable that it is independent of a commercial power supply because it is used in a humid bathroom. It can be said that it is one aspect of the water electrolysis device suitable for

In addition, since the faucet-mounted water electrolysis device is attached to the faucet of a general household where the load bearing capacity is not so high, it is required to be small and light. I can say there is.

Water electrolyzers for bathing water are required to be small and lightweight because they are carried in and out of the bathroom. is desirable and can be said to be one aspect of the water electrolysis device suitable for the present invention.

The water bottle type water electrolysis device is portable like a water bottle, and can be used to prepare electrolyzed water at a desired timing. It can be said that it is one aspect of the water electrolysis device suitable for the present invention because it is used in a state where it is soaked.

A spray-type water electrolysis device uses electrolyzed water for cleaning purposes, and is used, for example, in cleaning a bathroom in the same manner as a spray bottled bathroom detergent. This is also required to be small and lightweight from the viewpoint of hand-holding and handling, and it is expected that it will be used in humid places such as bathrooms, so it is desirable that it be independent of a commercial power source. It can be said that this is one aspect of a suitable water electrolysis device.

As described above, electrolyzed water broadly means water subjected to electrolysis, and so-called hydrogen water, oxygen water, acid water, alkaline ion water, hypochlorous acid-containing water, etc. are also included in the concept. .

The water electrolysis apparatus according to the present embodiment, including these aspects, is characterized in that a plurality of electrode plates to which positive and negative voltages are alternately applied are placed in a submersible space area formed in the housing. A water electrolysis device for generating electrolyzed water by arranging laminated electrode bodies laminated while maintaining a gap of mm, and electrolyzing water flowed into the space region, wherein the gap between the plurality of electrode plates Vibration permitting means for permitting vibration of each electrode plate is provided on the supporting portion that maintains the .

The submersible space area formed in the housing can be understood as a space in which water is stored or filled with water. Or, in the case of a bathwater type water electrolysis device, it is the space inside the housing that is flooded when it is submerged, or in the case of a water bottle type or spray type water electrolysis device, it is a part of the space of the reservoir where water is stored. All correspond.

The laminated electrode body is disposed in the above-mentioned submersible spatial region, and has a role of electrolyzing water present in the spatial region. It should be noted that the laminated electrode body does not necessarily need to be entirely immersed in water when the water electrolysis device is used. In the above-mentioned shower head type, faucet attachment type, and bath water injection type water electrolysis device, the entire laminated electrode body is immersed in water for use. Since the water in the water reservoir decreases, it is possible that a part of the laminated electrode assembly may be exposed from the water.

The water flowing into the spatial region does not necessarily have to be running water. In the above-mentioned shower head type and faucet type water electrolysis devices, running water is subject to electrolysis, but in bathwater type water electrolysis devices, natural convection and flowing water from a pump etc. It can be interpreted as the inflow of bath water into the space area when the water is discharged, and in the case of a water bottle type or spray type water electrolysis device, it can be interpreted as water replenished in the water storage part.

In particular, in the water electrolysis apparatus according to the present embodiment, the supporting portion that maintains the gaps between the plurality of electrode plates constituting the laminated electrode body is provided with vibration-allowing means for allowing vibration of each electrode plate. In particular, in the water electrolysis apparatus according to this embodiment, in order to reduce the electric power required for electrolysis, a plurality of electrode plates are laminated with a gap of 0.3 to 1.0 mm to form a laminated electrode body. Since the gap between the electrodes is narrow, the generated air bubbles tend to stay on the electrode plate, and it is more important to have a mechanism for quickly detaching them and efficiently circulating water on the surface of the electrode plate.

The vibration-allowing means is a means for efficiently electrolyzing by removing bubbles generated on the surface of the electrode plate from the surface of the electrode plate as soon as possible. It is preferable to vibrate the electrode plate in order to quickly detach the air bubbles generated on the surface of the electrode plate. In general, we sometimes see a phenomenon in which bubbles adhering to the inner wall of a glass filled with carbonated water or the inner wall of a bathtub detach due to vibration or impact. By applying this, in the present invention, the electrode plate is vibrated to accelerate the detachment of air bubbles. Therefore, a structure is adopted in which the supporting portion of the electrode plate is provided with the vibration-allowing means.

The supporting portion may be a recessed groove for each electrode plate formed in a wall arranged on the side surface of the laminated electrode body, that is, the surface on the side where the gap between the electrode plates can be seen, or may be an interposed groove for each gap between the electrode plates. It can be understood as a spacer provided.

In this embodiment, such a supporting portion is provided with vibration-allowing means. The vibration-allowing means does not support the vibration of each electrode plate in a fixed end state at the support portion, but is in a free end state or in a semi-free end state, that is, when the vibration transmitted through the electrode plate reaches the support portion. It is a means for supporting in a state in which vibration reflected by the fixed end and vibration reflected by the free end are generated.

In the case of such a vibration-allowing means, for example, in the case of a support portion that is supported in a free-end state, in the case of a groove, the width is wider than the thickness of the electrode plate, and the gap between the grooves (the width of the groove and the thickness of the electrode plate). This can be realized by setting the difference between the amplitudes to twice the amplitude (peak-to-peak amplitude) or more. That is, the gap (hereinafter, also referred to as the free end gap) that is at least twice the vibration amplitude functions as a vibration permitting means for the support portion that supports the free end state.

Also in the case of spacers, if the distance between the spacers is the distance between the electrode plates plus the gap between the free ends, it will function as a vibration-allowing means for the supporting portion that supports the electrodes in the free end state. Become.

On the other hand, in the case of a supporting portion that supports a semi-free end, the width of the concave groove is wider than the thickness of the electrode plate, and the difference between the gap between the concave groove and the thickness of the electrode plate is twice the amplitude. (hereinafter also referred to as the half-free end gap). If there is, it will function as a vibration-allowing means for the supporting portion that is supported in the semi-free state. Needless to say, the free end gap and the semi-free end gap are such that the electrode plate does not drop out of the groove or the spacer.

By providing such a vibration-allowing means in the supporting portion, electrolysis with low energy is realized by the laminated electrode body having a narrow space between the electrode plates, that is, the efficiency of electrolysis is improved, and the electrolysis electrode plate is improved. By rapidly removing adhering air bubbles, the surface portion of the electrode plate which is not in contact with water can be reduced, thereby preventing a decrease in efficiency of electrolysis.

Further, in order to enjoy these effects more remarkably, the water electrolysis apparatus may be provided with a vibration source for vibrating the electrode plate. By adopting such a configuration, it is possible to stably apply vibration to the electrode plate and improve the generation efficiency of electrolyzed water.

As a means for vibrating the electrode plate, it is effective to provide positive vibration inducing means such as a motor, a speaker, or a pump. However, even if they are not provided, first, the electrode plate or the laminated electrode body is made to have a "vibration-allowing structure", and the vibration from the surroundings induces the vibration of the electrode plate itself. It turned out to be effective. As a result, the increase in power required for electrolysis was suppressed and stabilized. As exemplified in each embodiment, the vibration from the surroundings includes vibration caused in each water conduit due to water flowing through the internal flow path, vibration due to convection of water, and vibration of the casing of the water electrolysis device.

In addition, the present application also provides a mode specialized for a water discharge terminal in relation to the water electrolysis device. Specifically, at the water discharge terminal connected to the downstream end of the water discharge equipment, a plurality of electrode plates to which positive and negative voltages are alternately applied are applied to the internal flow path of the water discharge terminal, and the voltage is 0.3 mm or more along the water flow direction. The present invention provides an electrolyzed water discharge terminal characterized in that it is divided into layers with a thickness of 1.0 mm.

In general, if you want to obtain electrolyzed hydrogen water from water discharge equipment such as shower equipment, kitchen or washbasin faucets, the size of the electrolytic cell to reliably electrolyze a large amount of water is increased. installation space is required.

That is, in order to equip a water discharge facility with the above-described conventional electrolyzed water generating device, it is necessary to interpose a large-sized device in the middle of the water supply channel of the water discharge facility. However, there was a problem that extra installation space had to be provided for the same device.

Furthermore, as the size of the apparatus increases, the power supplied to the electrolytic cell is required in excess of the amount of electrolyzed hydrogen water produced, resulting in a significant drop in energy efficiency.

In view of such circumstances, the present application efficiently generates electrolyzed hydrogen water with a high hydrogen concentration by reliably electrolyzing a large flow rate of water with low power consumption without being restricted by the limited space in water discharge equipment. It also has an aspect of providing an electrolyzed water discharge terminal capable of

Examples of water discharge equipment include shower equipment and faucets as described above, and examples of water discharge terminals connected to downstream ends of water discharge equipment include shower heads and faucets. The water supplied from the water discharge facility includes not only water supplied from the water supply source but also hot water heated via a water heater.

In particular, the shower head connected to the downstream end of the shower equipment emits a shower water flux consisting of countless fine thread-like water flows that maintain a certain amount of water and water pressure, thereby stimulating the user's skin surface and Gives relaxation effect.

It is known that a water flow rate of about 7 L/min or more is required to form such a shower water flux.

By dividing the internal flow path of the shower head with a plurality of electrode plates, the present invention does not require a large-scale electrolytic bath and its installation space as in the conventional technology, and can be used in a limited shower facility environment. A large volume of water supplied at 7 L/min is reliably converted to electrolyzed hydrogen water, and a shower water flux formed by the same electrolyzed hydrogen water can be formed, and the hydrogen water can eliminate active oxygen and stabilize the relaxation effect of the shower. It can also be said to be an electrolyzed water discharge terminal that can be obtained.

In addition, the present application also provides, with respect to the water electrolysis device, an embodiment specialized for a faucet-mounted water electrolysis device, a bathwater-type water electrolysis device, a water bottle-type water electrolysis device, and a spray-type water electrolysis device. These aspects will be clarified in each embodiment described later.

Further, as a further additional component, if the plurality of electrode plates is composed of at least five or more, the internal flow path of the water discharge terminal can be further divided into layers, and the hydrogen concentration is high. can be made more robust.

In addition, if spacers are provided at predetermined positions of the electrode plates to maintain the intervals between the plurality of electrode plates, the intervals between the electrode plates can be kept constant to stabilize the partitioned internal flow paths. It is possible to prevent the electrode plates from bending due to the flow pressure of water flowing into the internal flow path from the downstream end of the water discharge facility, and the occurrence of short circuits due to the electrode plates coming into inadvertent contact with each other.

Further, by arranging a constant flow rate body upstream of the internal flow channel divided into layers, the flow rate of water flowing into the divided internal flow channel can be made constant, and a rapid flow pressure can be generated. It is possible to prevent the electrode plate from being damaged by the load and prevent the short circuit more reliably.

In addition, if a switch for switching between supply and stop of power supply to the electrode plate is provided, the user can arbitrarily select generation and stop of electrolyzed hydrogen water, thereby suppressing unnecessary power consumption. be able to.

A control unit for controlling electric power supplied to the electrode plate, and water supply detection means for detecting water supply to the electrolyzed water discharge terminal. When the supply of water is detected, control is performed to supply power to the electrode plate, and when the supply of water is not detected, control is performed to stop the supply of power to the electrode plate, Electrolyzed hydrogen water can be reliably generated according to the inflow of water into the internal channel, and unnecessary power consumption in the electrode plate can be suppressed.

In addition, if the electrode plate is provided with a power storage body that supplies power to the electrode plate, power can be supplied to the electrode plate wirelessly, and the electrolyzed water discharge terminal can be operated without pulling a power cord. In addition, troubles such as electric shocks and short circuits can be avoided by adopting a waterproof structure.

[First embodiment]
Hereinafter, embodiments of the electrolyzed water discharge terminal according to the present embodiment will be described with reference to the drawings. FIG. 1 shows the appearance of the electrolyzed water discharge terminal according to the first embodiment, and FIG. 2 shows a longitudinal section of the electrolyzed water discharge terminal. Moreover, FIG. 3 shows a radial cross section of the grip portion of the water discharge terminal, FIG. 4 shows the arrangement configuration of the electrode plates, and FIG. 5 shows a side cross section of the power storage body and the charging base.

As shown in FIG. 1, the electrolyzed water discharge terminal H1 (hereinafter also referred to simply as the water discharge terminal) includes a grip portion 10 gripped by a user, a head portion 20 disposed at the tip of the grip portion 10, and a head portion 20 and a water discharger 30 arranged at the tip thereof constitute a main body.

As shown in FIG. 2, the grasping part 10 has a substantially cylindrical shape with a hollow interior and forms an internal flow path 11 through which supplied water flows.

A male screw portion 12 is formed on the outer circumference of the proximal end of the grip portion 10 to be screwed to the tip of a water supply hose 80, and the water discharge terminal H1 is connected to the water supply hose 80 connected to the water supply source.

The internal flow path 11 is a flow path through which the entire amount of running water from the water supply hose 80 flows, and is formed as an elongated hole.

In particular, the internal flow path 11 of this embodiment is formed by drilling a rectangular elongated hole along the longitudinal direction at the central portion of the closing body 13 in which the inner wall of the grip portion 10 is formed thick.

The internal flow path 11 is divided into layers along the direction of water flow by a plurality of electrode plates 41 to which positive and negative voltages are alternately applied.

That is, the water discharge terminal H1 of the present embodiment has the blocking body 13 interposed inside the water discharging terminal H1, and the internal flow path 11 formed in the same blocking body 13 is divided into layers by the plurality of electrode plates 41 .

As shown in FIG. 3(a), on the inner peripheral surface of the grip portion 10 of the water discharge terminal H1 (the inner peripheral surface of the closing body 13), a ridge with a thickness of 0.3 mm to 1.0 mm is formed parallel to the diameter direction in a cross-sectional view. A plurality of (in this embodiment, four) projections 13a are formed at intervals equal to the thickness of the electrode plate 41 .

A recessed groove having a width equal to the thickness of the electrode plate 41 formed by the projection 13a forms a fitting groove 13b into which both edges of the electrode plate 41 in the short direction are inserted.

That is, the inner peripheral wall forming the internal flow path 11 of the water discharge terminal H1 is formed with fitting grooves 13b along the shape of both edge portions of the plurality of electrode plates 41 in the short direction. That is, the plurality of electrode plates 41 integrally form a laminated electrode body, and the internal flow path 11 serves as a submerged spatial area formed in the housing of the water discharge terminal H1.

By fitting both edge portions of the electrode plates 41 into the fitting grooves 13b, the plurality of electrode plates 41 can be arranged horizontally in parallel with the diameter of the internal flow path 11 at predetermined intervals in a cross-sectional view. Separate by hanging.

In addition, ridges 13a are positioned at both edges in the width direction between the electrode plates 41 that are fitted in the fitting grooves 13b and are opposed to each other, and serve as spacers to maintain the spacing between the electrode plates 41. Fulfill.

The supporting portion of the electrode plate 41 constituted by the protrusion 13a and the fitting groove 13b has a width L1 of the fitting groove 13b wider than the thickness L2 of the electrode plate 41, as shown in FIG. You can also use

With this configuration, a gap L3 (=L1-L2) is formed, which is the difference between the width L1 of the fitting groove 13b and the thickness L2 of the electrode plate 41. It functions as a vibration permitting means for permitting vibration of the plate 41 .

The vibration generated in the gripping portion 10 by the water flowing through the internal flow path 11 is imparted to the electrode structure having the above-described vibration-allowing means, so that the bubbles adhering to the electrolytic electrode plate are quickly released, and the water is removed. By reducing the surface area of the electrode plates that are not in contact with each other, the production efficiency of electrolyzed water can be improved significantly.

The length L3 of the gap can be configured to be two times or more, or less than two times, the amplitude of the vibration generated by the holding portion 10, which is the vibration source described above. The lengths of L1, L2, L3, etc. in FIG. 3(b) are exaggerated for better understanding of the invention.

In addition, the plurality of electrode plates 41 are alternately connected to the control unit 40 to be described later via a lead wire, and the cathode plates 41a and the anode plates 41b are alternately arranged in layers in the internal flow path 11. .

The inner flow channel 11 thus divided into layers by the plurality of electrode plates 41 is surrounded by the blocking member 13 so that the positive and negative electrode plates 41 are opposed to each other, and the electrolytic flow channel 42 is formed between the positive and negative electrode plates 41 . The electrolytic flow channel layer 43 consisting of the electrolytic flow channels 42 of .

The electrode plate 41 arranged in the internal flow path 11 is a strip-shaped metal flat plate formed with a dimension that allows the internal flow path 11 to be divided into layers. An example of the dimensions of the electrode plate 41 is length: 50 mm to 200 mm, width: 0.5 mm to 25 mm, plate thickness: 0.1 mm to 1.0 mm, more preferably length: about 100 mm to 150 mm, width: 10 mm to 25 mm, Thickness: 0.2mm to 0.5mm. As the material of the electrode plate 41, for example, a titanium plate plated with platinum can be used.

In addition, the number of the plurality of electrode plates 41 is at least five, and may be increased as appropriate according to the dimensions of the internal flow path 11 to be arranged, the dimensions of the electrode plate 41 itself, and the width of the electrolysis flow path 42 to be formed. can be done.

By increasing the number of electrode plates 41 to five or more in this way, it is possible to form an electrolytic flow channel layer 43 in which the internal flow channel 11 is divided into at least four or more electrolytic flow channels 42 .

As the number of electrode plates 41 increases, the contact area between the electrode plates 41 and water increases. As a result, the contact area between the hydrogen generated on the electrode plate 41 and water is increased, and the efficiency of dissolving hydrogen in water is improved, so that the concentration of dissolved hydrogen can be increased. In addition, although the details will be described later, the power consumption required for electrolysis can be reduced.

As described above, the number of electrode plates 41 is preferably as large as possible from the viewpoint of electrolysis efficiency. From a restrictive point of view, too much is not suitable.

Therefore, the number of electrode plates 41 is preferably within a reasonable range from the viewpoint of efficiency of electrolysis and the viewpoint of cost and space constraints, and is preferably 5 or more and 10 or less.

In addition, as shown in FIGS. 3 and 4, the water discharge terminal H1 according to the present embodiment includes five electrode plates 41 of the same shape and size which are arranged parallel to each other at predetermined intervals so as to overlap each other along the internal flow path 11 . , to form an electrolytic flow path layer 43 having a substantially rectangular parallelepiped shape and having four parallel electrolytic flow paths 42 .

In addition, the layer thickness of one layer in the partitioned internal channel 11, that is, the interval width between the plurality of electrode plates 41 is set to 0.3 mm to 1.0 mm.

When the interval width between the electrode plates 41 is made smaller than 0.3 mm, the voltage required for water electrolysis approaches 1.23 V, which is the oxidation-reduction potential difference between oxygen and hydrogen, thereby minimizing the power consumption required for electrolysis. However, the running water flowing into the internal flow path 11 increases the water pressure load on the electrode plates 41, causing the electrode plates 41 to bend inadvertently and cause a short circuit, as well as increasing the pressure loss of the running water. There is a possibility that the shower water flux cannot be formed from the water discharger 30 .

On the other hand, when the interval width between the plurality of electrode plates 41 is larger than 1.0 mm, the cross-sectional area of the internal flow path 11 is widened, so that the velocity of the flowing water relative to the electrode plates 41 is relatively decreased, and the Hydrogen locally saturates the running water, increasing the proportion of hydrogen that cannot be completely dissolved and forms bubbles, and as a result, the amount of dissolved hydrogen decreases. In addition, as the distance between the opposing electrode plates 41 increases, the voltage increases and the power consumption required for electrolysis increases.

Therefore, by setting the interval width between the plurality of electrode plates 41 to 0.3 mm to 1.0 mm, short-circuiting between the electrode plates 41 can be prevented without interfering with the flow of running water in the internal flow path 11, and the voltage required for electrolysis can be reduced. By reducing the power consumption, stable electrolysis is realized with low power consumption, and the shower water flux formed by high-concentration electrolyzed hydrogen water can be discharged.

The interval between the plurality of electrode plates 41 does not have to be constant as long as it is in the range of 0.3 mm to 1.0 mm. The distance between the outer electrode plates 41 may be different.

For example, if a plurality of electrode plates 41 are arranged at intervals that gradually widen from the axial center side to the outermost side of the internal flow path 11, as the flow pressure rises, the gap between the electrode plates 41 facing each other will increase. It is also possible to preferentially direct flowing water to make stable electrolysis more robust.

Thus, in the water discharge terminal H1 according to the present embodiment, the internal flow path 11 is divided by the plurality of electrode plates 41 along the water flow direction, thereby forming the electrolysis flow path 42 in the internal flow path 11 and achieving the electrolysis distance. is lengthened, and the entire area of the internal flow channel 11 is formed into a layered electrolytic flow channel layer 43 in which a plurality of electrolytic flow channels 42 are arranged in parallel, enabling highly efficient electrolysis in spite of the extremely narrow space.

Further, as shown in FIG. 2, a constant flow body 14 is arranged upstream of the internal flow path 11 divided into layers. More specifically, the constant flow body 14 is arranged at a rear position inside the grip portion 10 .

The constant flow body 14 may be any body as long as it can keep the water pressure and water volume of the flowing water flowing into the electrolysis channel 42 constant. A constant flow valve having an orifice with an opening smaller than the inner diameter of the upstream side can be employed.

Such a constant flow valve is equipped with a biasing spring that always biases the valve body toward the upstream side. , a method that utilizes the difference in the opening of the orifice, and a method that forms the orifice from an elastic material and elastically deforms the opening.

Also, a trap filter for removing contaminants contained in the water to be supplied may be disposed upstream of the internal flow path 11 divided into layers, that is, at a rear position inside the grip portion 10 .

In particular, from the viewpoint of extremely narrowing the electrolytic flow path 42 divided into layers, the provision of the trap filter can remove impurities and reliably prevent a short circuit between the electrode plates 41 .

The trap filter can be appropriately selected according to the type and size of the contaminants. As an example of the trap filter, a metal mesh filter, a non-woven fabric filter, an activated carbon filter, a ceramic filter, or the like can be used singly or in combination according to the type and size of the contaminants.

A switch 44 for switching between supply and stop of power supply to the electrode plate 41 is arranged on the outer peripheral wall of the grip part 10 .

The switch 44 may be a waterproof switch. For example, a capacitive touch sensor that reacts with the capacitance of a hand, a mechanical switch with a waterproof structure, a slide type, a push button type, or the like can be adopted.

The switch 44 is configured to switch between supplying and stopping power to the electrode plate 41 in accordance with the switching operation of the water discharger 30 configured to switch the water discharge state between a shower-like water spray and a straight water discharge. It is also an idea to

For example, the switch 44 stops the power supply to the electrode plate 41 when the water discharger 30 is switched to straight water discharge, and stops the power supply to the electrode plate 41 when the water discharger 30 is switched to shower water spray. of power may be supplied.

As shown in FIG. 2, the head unit 20 is formed in a hollow interior, and the internal space is separated by a partition wall 21 to accommodate a control unit storage space 22 in which the control unit 40 is stored on the upper side and an internal space on the lower side. It is divided into an electrolytic hydrogen water inflow space 23 located on the downstream side of the flow path 11 .

The electrolytic hydrogen water inflow space 23 communicates with the internal flow paths 11 partitioned by the plurality of electrode plates 41 , and is a space where water flowing down the electrolytic flow paths 42 forming the electrolytic flow path layer 43 joins.

The bottom surface of the electrolyzed hydrogen water inflow space 23 forms a water sprinkling surface 31 having a plurality of water sprinkling holes 32 , forming a water discharge portion 30 .

The control unit 40 arranged in the control unit housing space 22 is a part that controls the supply and stop of power supply to the electrode plate 41 by connecting to the power storage body 50 described later.

In addition, the control unit 40 is connected to functional units related to the generation of electrolytic hydrogen water, such as a water supply detecting means 45 for detecting water supply to the electrolyzed water discharge terminal H1, a switch 44, and a hydrogen water generation display means 64. there is

The water supply detection means 45 is provided on the peripheral wall of the grip portion 10 of the water discharge terminal H1. Specifically, the water supply detection means 45 is arranged at a position downstream of the internal flow path 11 partitioned by the plurality of electrode plates 41 on the peripheral wall of the grip portion 10 .

The water supply detection means 45 can detect the presence or absence of water flowing into the internal channel 11 and transmit the detected signal to the control section 40 . The water supply detection means 45 is not particularly limited as long as it converts the presence or absence of water flow and the flow rate of water (hereinafter simply referred to as water flow rate) into an electric signal. A transducer can be employed that can also detect water currents.

The water supply detection means 45 of the present embodiment is a capacitance sensor, connected to the control unit 40, connected to the capacitance sensor unit 45a stored in the control unit storage space 22, and connected to the capacitance sensor unit 45a. Two electrode pads 45b and 45b' are arranged on the inner peripheral surface of the part 10 so as to face each other along the direction of water flow.

With such a configuration, the capacitance sensor section 45a can detect the water flow as the capacitance generated in the electrode pads 45b and 45b' changes depending on whether the water is stationary or flowing.

The position at which the water supply detection means 45 is provided is not particularly limited as long as it is not interfered with by the plurality of electrode plates 41, and is positioned upstream of the internal flow path 11 partitioned by the plurality of electrode plates 41. It may be at a downstream position.

For example, when the water supply detection means 45 is provided upstream of the internal flow path 11 partitioned by the plurality of electrode plates 41, two water supply detection means 45 are provided in the electrolyzed hydrogen water inflow space 23 inside the head portion 20 along the water flow direction. It is also an idea to dispose the two electrode pads 45b and 45b' facing each other with a predetermined interval and dispose the capacitive sensor section 45a in the control section storage space 22. FIG.

Further, when the water supply detecting means 45 is provided upstream from the internal flow path 11 divided by the plurality of electrode plates 41 , it may be provided inside the water supply hose 80 .

The water discharge terminal H1 also includes a power storage body 50 that supplies power to the electrode plate 41 . In particular, the power storage unit 50 according to the present embodiment has a connection structure in which it is connected to the power receiving unit of the main body of the water discharge terminal H1 via the built-in power transmitting unit 54 in a non-contact manner. It is configured to supply power to

As shown in FIGS. 2 and 5, the power storage body 50 includes a substantially cylindrical and hollow power storage body case 51, a power receiving coil 52a disposed on the inner upper surface of the power storage body case 51, and an inner center of the power storage body case 51. a power supply circuit 55 provided below the power storage body 53; and a power transmission coil 54a provided on the bottom surface inside the power storage case 51.

Although two power storage body bodies 53 according to the present embodiment are arranged in parallel, the voltage required for electrolysis is reduced as much as possible by the spacing between the electrode plates 41 arranged facing each other and the material of the electrode plates 41. As a result, it is of course possible to reduce the volume and size of the power storage body 53 .

The power receiving coil 52 a functions as a power receiving section 52 corresponding to the power transmitting section 62 of the charging stand 60 , which will be described later, and is connected to the power storage body 53 via the power supply circuit 55 .

The power transmission coil 54a functions as a power transmission section 54 corresponding to a power reception section provided in the main body of the water discharge terminal H1, which will be described later, and is connected to the power storage body main body 53 via the power supply circuit 55 in the same manner as the power reception coil 52a. there is

The power supply circuit 55 has AC/DC conversion, DC/DC conversion, a converter function that performs AC/AC conversion, and/or an inverter function that performs DC/AC conversion. It performs conversion control, charging of the power storage body 53, and adjustment control to a constant voltage suitable for electromagnetic coupling between the power transmission unit 54 and the power reception unit 46, which will be described later.

Moreover, the power storage unit 50 is detachably attached to the main body of the water discharge terminal H1. More specifically, as shown in FIG. 2 , a recessed fitting groove 24 is formed in the outer wall of the head section 20 near the control section 40 along the outer shape of the power storage body 50 . The body 50 is detachably attached to the head portion 20 of the water discharge terminal H1.

In the vicinity of the control unit 40 inside the head unit 20 , a power reception coil 46 a is provided as a power reception unit 46 connected to the control unit 40 and corresponding to the power transmission unit 54 of the power storage body 50 . More specifically, power receiving coil 46 a is arranged near the bottom surface of fitting groove 24 at a position corresponding to power transmitting coil 54 a of power storage body 50 .

Then, when the power storage unit 50 is mounted in the fitting groove 24 of the head unit 20, the power transmission coil 54a of the power storage unit 50 and the power reception coil 46a inside the head unit 20 approach each other to generate a magnetic field therebetween. Let

Specifically, the AC voltage converted from the DC voltage via the power supply circuit 55 is applied to the power transmission coil 54a to supply an AC current to the power transmission coil 54a of the power storage unit 50 and the power reception coil 46a inside the head unit 20. Electromagnetic induction is generated, and electric power is generated by the electromagnetic induction.

That is, the power transmission unit 54 of the power storage unit 50 and the power reception unit 46 of the head unit 20 have a connection structure in which they are electromagnetically coupled to each other.

Therefore, the power storage unit 50 has no contacts and is completely waterproof, preventing electric leakage and allowing power to be supplied to the electrode plate 41 via the control unit 40 .

Also, as shown in FIG. 5, the power storage unit 50 is charged by placing it on the mounting surface of a charging stand 60 connected to a commercial power source via an outlet cable 61 .

More specifically, the charging base 60 has a power transmission coil 62 a as a power transmission unit 62 on the mounting surface side inside thereof, similarly to the power storage body 50 , and transmits power with an AC voltage via the power supply circuit 63 . Electromagnetic induction is generated between the power transmission coil 62a of the charging stand 60 and the power reception coil 52a of the power storage body 50 by applying an alternating current to the coil 62a.

In other words, the charging stand 60 and the power storage body 50 are electromagnetically coupled so that the power storage body main body 53 inside the power storage body 50 can be charged.

In addition to the electromagnetic induction method used in this embodiment, the contactless power supply method may be, for example, an electromagnetic resonance method, an electric field coupling method, or a radio wave method. Of course, there is no limitation as long as it is a method that can be used.

Next, the electrical configuration of the water discharge terminal H1 will be described with reference to FIG. FIG. 6 is a block diagram showing an electrical configuration of the water discharge terminal H1.

As shown in FIG. 6 , the control section 40 includes a CPU 47 , a control section main body 48 and a power supply circuit 49 .

The CPU 47 is composed of a ROM 47a and a RAM 47b. The ROM 47a stores programs and the like necessary for the processing of the CPU 47, and the RAM 47b functions as a temporary storage area when the programs and the like are executed.

For example, a predetermined area of the ROM 47a stores a program for implementing various processes necessary for supplying power to the electrode plate 41 and stopping the power supply.

More specifically, the program includes a manual switching step for starting or stopping power supply to the electrode plate 41 in response to a switching operation signal from the switch 44, and an electrode switching step in response to a water flow detection signal from the water supply detection means 45. It includes an automatic switching step for starting or stopping power supply to the plate 41 and an electrode switching step for switching the positive and negative voltages on the electrode plate 41 after a predetermined period of time has elapsed.

Information input from the input signal from the switch 44 or the water supply detecting means 45 is stored at a predetermined address on the RAM 47b and referred to when the CPU 47 executes various programs.

The controller main body 48 is composed of analog and/or digital circuits, and is mainly composed of an electrode control circuit 48a for generating hydrogen and a safety circuit 48b. The control unit main body 48 receives signals that the CPU 47 takes in and processes from the outside, and controls the entire circuit.

The electrode control circuit 48a is a circuit for making the current flowing through the electrode plate 41 constant, and controls the voltage according to the water flow rate and water quality (electrical conductivity). In addition, the electrode control circuit 48 a controls the switching of positive and negative voltages applied to the electrode plate 41 based on processing signals from the CPU 47 .

The safety circuit 48b is a circuit for monitoring temperature rise with a thermistor or a temperature sensor, and controlling the circuit to be cut off when abnormal heat generation is detected. Moreover, the safety circuit 48b stops the power supply to the electrode plate 41 even when an abnormal overcurrent flows due to short-circuiting of the electrodes or the like.

The power supply circuit 49 has an inverter function and/or a converter function as described above, converts the power transmitted from the power storage unit 50 into a constant voltage, and supplies power to each functional unit. Specifically, the voltage is converted and increased/decreased according to the signal from the control unit main body 48 . In particular, when feeding power to the electrode plate 41, the voltage is controlled so that a constant current can flow while monitoring the current.

As described above, in the control unit 40, the control unit main body 48 of the water discharge terminal H1 controls various control circuits in response to processing signals from the CPU 47 that receives external information, starts and stops power supply to the electrode plate 41, and controls a plurality of electrodes. It is configured to switch the positive and negative of the voltage on the plate 41 .

Specifically, when the control unit 40 receives a power supply signal associated with the switching operation of the switch 44, the control unit 40 performs control to start supplying power to the electrode plate 41, while receiving a power supply stop signal. If so, control is performed to cut off the power supply to the electrode plate 41 .

Further, the control unit 40 controls the supply of electric power to the electrode plate 41 when a power supply signal associated with the detection of water flow is received by the water supply detecting means 45, and the power supply signal associated with the detection of stoppage of water flow. is received, the power supply to the electrode plate 41 is stopped.

In addition, the control unit 40 switches the polarity of the voltage on each electrode plate 41 after a certain period of time has elapsed, thereby preventing scale from adhering to the electrode plate 41 due to electrolysis and removing the adhered scale.

Further, the control unit 40 is connected to a hydrogen water generation display means 64 for informing the user of generation of electrolyzed hydrogen water by the water discharge terminal H1.

As an example of the hydrogen water generation display means 64, an LED light is provided at a predetermined position on the outer wall of the head unit 20, blinking in red when electrolyzed hydrogen water is generated, and blue when electrolyzed hydrogen water is not generated. may be configured to flash on and off.

The hydrogen water generation display means 64 may be controlled by the control section 40 so as to be interlocked with the switch 44 and the water supply detection means 45 described above. Furthermore, it is also possible to control by connecting to a hydrogen detection sensor such as a hydrogen gas sensor or a pH sensor provided in the internal channel 11 without using the control unit 40 .

According to the water discharge terminal H1 having such a configuration, electrolyzed hydrogen water is generated as follows.

When water is supplied from the water supply hose 80 connected to the male screw portion 12 of the water discharge terminal H1, the water flows into the internal flow path 11. As shown in FIG. Specifically, the supplied water is branched by a plurality of electrode plates 41 partitioning the internal flow path 11 and introduced into a plurality of electrolytic flow paths 42 running in parallel.

Next, the water supply detection means 45 detects running water, and the controller 40 applies alternating positive and negative voltages to the plurality of electrode plates 41 according to the water flow detection signal transmitted by the water supply detection means 45 .

Next, the water in the internal flow path 11 is electrolyzed while flowing down between the electrode plates 41 arranged opposite to each other, and the hydrogen gas generated on the surface of the cathode plate 41a dissolves to become electrolyzed hydrogen water.

In the electrolyzed hydrogen water generated by the water discharge terminal H1, since there is no diaphragm between the electrode plates 41 facing each other, the acidic water generated by the anode plate and the alkaline water generated by the cathode plate are electrolytically flowed. Almost neutral electrolyzed hydrogen water is mixed in the course of flowing down the path 42 .

The electrolyzed hydrogen water generated in the internal flow path 11 reaches the electrolyzed hydrogen water inflow space 23 of the head portion 20 and is discharged through the water sprinkling surface 31 of the water discharger 30 .

Then, after a certain period of time has passed, the control unit 40 applies to each electrode plate 41 a voltage with the positive and negative polarities reversed to switch the cathode plate 41a to the anode plate 41b and the anode plate 41b to the cathode plate 41a.

Here, the amount of dissolved hydrogen in the electrolyzed hydrogen water generated by the water discharge terminal H1 and the thickness of one layer in the internal flow path 11 divided into layers, that is, the interval width between the plurality of electrode plates 41 (hereinafter simply referred to as the layer thickness ) and the relationship between the voltage applied to the electrode plate and the layer thickness will be described with reference to the drawings. FIG. 7 is a graph showing the relationship between the amount of dissolved hydrogen in electrolyzed hydrogen water and the layer thickness. FIG. 8 is a graph showing the relationship between the voltage applied to the electrode plate and the layer thickness. These are the results of measurement under constant conditions of a current value of 1 A and a flow rate of 7 L/min.

One of the notable points of the water discharge terminal H1 according to the present embodiment is that the internal flow path 11 is divided into layers with an extremely narrow width of 0.3 mm to 1.0 mm by a plurality of electrode plates 41. It is possible to circulate the entire amount of the large flow of water supplied per unit time, and electrolyze the same flow during the flow process to generate high-concentration electrolyzed hydrogen water with low power.

As shown in FIG. 7, the amount of dissolved hydrogen for each layer thickness in the internal channel divided into layers increases as the layer thickness becomes narrower.

That is, the cross-sectional area of the internal flow path 11 becomes narrower as the layer thickness is reduced, so that the flow velocity relative to the electrode plate 41 increases, and the generated hydrogen is sufficiently dissolved in the flowing water (hydrogen effect of increasing dissolved efficiency).

As a result, even if the water flow rate is 7 L/min or more, it is possible to maintain the dissolved hydrogen amount of about 50 ppb or more and to generate the electrolyzed hydrogen water having the above-described active oxygen scavenging ability.

On the other hand, when the layer thickness is increased, the water flow rate is relatively lowered, and the amount of water dissolved in the generated hydrogen is reduced. That is, if the layer thickness is greater than 1.0 mm, hydrogen-saturated hydrogen water is generated locally, and a large amount of hydrogen cannot be dissolved and is discharged as bubbles, resulting in a decrease in the amount of dissolved hydrogen.

Therefore, as shown in FIG. 7, by narrowing the layer thickness to 1.0 mm or less, it is possible to secure a dissolved hydrogen amount of 50 ppb or more even when the water flow rate is 7 L/min or more. Further, when the layer thickness is increased, the voltage becomes higher and the power consumption required for electrolysis increases. Therefore, from the viewpoint of power reduction, it is preferable to narrow the layer thickness to 1.0 mm or less.

In this way, the internal flow path 11, which is divided into a layer thickness of 1.0 mm or less by a plurality of electrode plates 41, effectively electrolyzes the entire amount of water even if the flow rate is a large flow rate of 7 L/min or more. It is possible to stably generate electrolyzed hydrogen water with a high dissolved hydrogen content.

A notable point of the water discharge terminal H1 according to the present embodiment is that, as described above, a large volume of water is divided into extremely narrow layers with a thickness of 0.3 mm to 1.0 mm by the plurality of electrode plates 41. The passage 11 minimizes the voltage applied to the electrode plate 41 required to generate electrolyzed hydrogen water with a dissolved hydrogen content of about 40 ppb to 50 ppb or more, thereby reducing the power required for electrolysis. be done. FIG. 8 shows the relationship between the layer thickness of the internal channel and the applied voltage (V) required to flow an electrolytic current of current value 1A. The water flow rate was kept constant at 7 L/min.

As shown in FIG. 8, when the layer thickness of the partitioned internal channels is reduced, the voltage applied to the electrode plate 41 is a relatively small value.

The reason why the applied voltage required for electrolysis decreases when the layer thickness is narrowed in this way is that the thickness of the water between the electrode plates, that is, the thickness of the electrolyte layer, decreases as the layer thickness decreases. This is because the conversion energy is relatively lowered.

That is, as shown in FIG. 8, the decrease in the voltage required to flow a constant current with the narrowing of the layer thickness indicates the effect of reducing the power required for electrolysis (improve the efficiency of hydrogen generation). improvement effect).

On the other hand, when the layer thickness is less than 0.3 mm, the voltage required for electrolysis of water approaches 1.23 V, which is the redox potential difference between oxygen and hydrogen. It makes less sense to do so.

Furthermore, if the layer thickness of the internal flow path 11 is too narrow, the water pressure load on each electrode plate 41 increases due to the water flowing into the internal flow path 11 , and each electrode plate 41 unintentionally bends to cause a short circuit. At the same time, the pressure loss of the running water is increased, and there is a possibility that the shower water flux cannot be formed from the water discharger 30 .

Therefore, it is preferable that the layer thickness of the internal flow path 11 is not narrowed more than necessary, and the layer thickness is preferably 0.3 mm or more as a range in which both the power reduction effect and the pressure rise prevention are achieved.

That is, the power consumption required for electrolysis can be reduced as much as possible by arranging the electrode plates 41 facing each other in the range of 0.3 mm or more in the plurality of electrode plates 41 that divide the internal flow path 11 . can be done.

Further, as a typical example of the electrolyzed water discharge terminal H1 according to the first embodiment, the dissolved hydrogen amount (ppb) of electrolyzed hydrogen water generated by the internal flow path 11 divided into layers with a thickness of 0.6 mm by a plurality of electrode plates and the flow rate (L/min) supplied to the same internal flow path 11 was measured. The results are shown in FIG.

Five electrode plates 41 made of platinum-plated titanium and having dimensions of 150 mm in length, 20 mm in width, and 0.5 mm in thickness are used as a typical example of the electrolyzed water discharge terminal H1 according to the first embodiment. In addition, the current value was kept constant at 1A.

As shown in Fig. 9, the amount of dissolved hydrogen tends to decrease gradually as the water flow increases. Even at the flow rate, the amount of dissolved hydrogen is maintained at 50 ppb or more, and the electrolyzed hydrogen water having the above-described active oxygen scavenging ability is produced.

In addition, the voltage required for electrolysis is a constant value of about 5.2 V in the section where the water flow rate is 3 L/min to 9 L/min, that is, a constant low power of about 5.2 W. Sustained electrolysis was possible even when used for

As described above, the water discharge terminal H1 has a configuration that reduces the power required to electrolyze the water supplied to the internal flow path 11, so that a small power source such as the power storage body 50 described above can be used. Continuous electrolysis is possible even if there is a problem, and it is possible to stably generate high-concentration electrolyzed hydrogen water. Note that the basic configuration and additional configuration of the water discharge terminal H1 described above can also be employed in other embodiments described later, and the effects of these can, of course, be enjoyed.

[Second embodiment]
Next, a water discharge terminal H2 according to the second embodiment will be described with reference to FIG.
FIG. 10 shows a side cross section of the grip portion 10 of the water discharge terminal H2. In the following description, the same components as those of the water discharge terminal H1 are denoted by the same reference numerals, and descriptions thereof are omitted.

The water discharge terminal H2 has substantially the same configuration as the water discharge terminal H1, and is configured to be able to discharge electrolytic hydrogen water, but the shape of the plurality of electrode plates 41 that divide the internal flow path 11 is modified. The configuration is different in one point.

That is, as shown in FIG. 10, the plurality of electrode plates 41c are formed in a plurality of large and small cylindrical shapes, and along the direction of water flow in the internal flow path 11, each electrode plate 41c is concentrically spaced from the axis by 0.3 mm. By arranging them in layers with an interval of ~1.0 mm, the internal flow path 11 is divided into layers with a thickness of 0.3 mm to 1.0 mm.

Specifically, the electrode plates 41c are cylindrical bodies with a hollow interior, and between the adjacent electrode plates 41c, one electrode plate is aligned in the radial direction by 0.3 mm to 1.0 mm from the axis of the other electrode plate. The radius of the electrode plate is elongated or contracted.

Further, the internal flow path 11 according to the present embodiment is formed as a substantially cylindrical hole inside the grip portion 10 in a cross-sectional view.

Then, a plurality of cylindrical electrode plates 41c are concentrically arranged in a nested manner with respect to the internal channel 11, and a cylindrical gap of 0.3 mm to 1.0 mm is formed as an electrolytic channel 42c. 11 is an electrolytic flow path layer 43c having a substantially annual ring shape in cross section and comprising a plurality of electrolytic flow paths 42c.

A spacer (not shown) having a thickness of 0.3 mm to 1.0 mm is interposed at a predetermined position between the adjacent electrode plates 41c to maintain the distance between the adjacent electrode plates 41c.

The outermost electrode plate 41c has an outer diameter equal to the inner diameter of the grip portion 10, and its outer peripheral wall is formed so as to be in close contact with the inner peripheral wall of the grip portion 10 (inner peripheral wall of the closing member 13).

With such a configuration, the water discharge terminal H2 can quickly guide the entire large volume of water supplied from the water supply hose 80 to the internal flow path 11, and can reduce the pressure loss of the inflowing water as much as possible. .

That is, in the internal flow path 11 related to the water discharge terminal H2, each electrolysis flow path 42c is formed in a cylindrical layer shape along the inner peripheral surface shape of the water supply hose 80, so that the water supplied from the water supply hose 80 is shaped like a flowing water. is smoothly introduced into each layered electrolytic flow path 42c while holding as much as possible, and electrolysis can be performed between the adjacent electrode plates 41c.

[Third embodiment]
Next, a water discharge terminal H3 according to a third embodiment will be described with reference to FIG.
FIG. 11 shows a longitudinal section of the grip portion 10 of the water discharge terminal H3.

The water discharge terminal H3 has substantially the same configuration as the water discharge terminal H1, but is different in that the shape of the plurality of electrode plates 41d that divide the internal flow path 11 is modified similarly to the water discharge terminal H2. ing.

That is, as shown in FIG. 11, the plurality of electrode plates 41d are curved in a wave-like shape along the direction of water flow, and are 0.3 mm to 1.0 mm thick so as to match the phases of the internal flow passages 11 with each other. By stacking and arranging them parallel to each other at intervals, the internal flow path 11 is divided into visible layers with a thickness of 0.3 mm to 1.0 mm in side section.

The electrode plate 41d is a corrugated plate having an uneven surface formed by being curved so as to repeat unevenness of the same amplitude. The waveform of the electrode plate 41d may be any of sine wave, rectangular wave, trapezoidal wave and triangular wave.

In addition, the ridges 13a and the fitting grooves 13b on the inner peripheral surface of the gripping portion 10 (the inner peripheral surface of the closing member 13) are formed in a wave shape along the shape of both edge portions in the short direction of the electrode plate 41d. there is

The internal flow path 11 is partitioned by a plurality of wavy electrode plates 41d to form wavy electrolytic flow paths 42d in a cross-sectional view in the longitudinal direction. layer 43d.

With such a configuration, despite the space restriction of the internal flow path 11 at the water discharge terminal H3, the corrugated electrode plate 41d arranged opposite to the internal flow path 11 maximizes the water electrolysis area. In addition to being able to expand, the length of the wavy electrolytic flow path 42d along the longitudinal direction of the internal flow path 11 can be increased to lengthen the electrolysis distance of water.

[Fourth Embodiment]
Next, a water discharge terminal H4 according to a fourth embodiment will be described with reference to FIG. FIG. 12 shows a perspective view of a plurality of electrode plates 41 that divide the internal flow path 11 of the water discharge terminal H4.

The water discharge terminal H4 has substantially the same configuration as the water discharge terminal H1, but differs in that spacers 15 are provided at predetermined positions on the surface of the electrode plate 41 that divides the internal flow path 11. FIG.

That is, as shown in FIG. 12, a plurality (four in this embodiment) of spacers 15 having a predetermined thickness are arranged in spots on the plate surface 41e of the electrode plate 41 at predetermined intervals.

The spacer 15 has a thickness of 0.3 mm to 1.0 mm so as to maintain the intervals between the electrode plates. As the material of the spacer 15, a waterproof material such as resin can be adopted.

Also, the shape of the spacer 15 is a rectangular parallelepiped shape, but is not limited to this, and may be, for example, a substantially triangular prism shape or a substantially cylindrical shape. For example, if the triangular prism-shaped spacers 15 are arranged on the electrode plate 41 with their corners facing the inflow direction of the flowing water, the flow resistance of the water flowing through the electrolytic flow channel 42 can be reduced as much as possible. be able to.

Moreover, the size of the spacer 15 may be any size as long as it does not block the electrolytic flow path 42 .

Further, the arrangement position of the spacer 15 on the electrode plate 41 is not particularly limited as long as it is a position that does not hinder the flow of water. Four spots are scattered near the corners avoiding the center of the flowing water.

With such a configuration, by simply stacking a plurality of electrode plates 41 in layers, the spacers 15 are interposed between the opposing electrode plates 41 to form a plurality of electrolytic flow paths 42 having a thickness of 0.3 mm to 1.0 mm. It is possible to form an electrolytic flow path layer 43 made of.

Furthermore, together with the protrusion 13a of the closing member 13, the function of maintaining the distance between the plurality of electrode plates 41 can be made more solid, and the bending contact between the electrode plates 41 due to a large amount of flowing water can be prevented. Short circuits can be reliably prevented.
