By the way, in order to use the water discharged from the shower head as electrolytic hot water, electric power for electrolyzing the hot water is naturally required.

It is conceivable that this electric power can be obtained from a commercial power source, for example, but it is desirable that the running distance of the power supply line is as short as possible in order to prevent electric leakage or electric shock in the vicinity of water such as a bathroom or a washbasin.

In this respect, if a storage battery is adopted, electrolysis can be performed by obtaining electric power from the storage battery, so that the electrolytic hot water can be discharged in a state independent of the commercial power source at the time of use.

However, if a storage battery is used, it will eventually need to be charged after the electrolyzed hot water is obtained, but if the storage battery is integrated with the shower head, for example, the shower head must be removed from the water supply hose for charging. It's complicated.

Further, when normal hot water is discharged without electrolysis, the weight of the shower head is increased even though the storage battery is temporarily unnecessary.

This is a portion for integrating the ring 33 into the electrolytic unit 23.

The base portion 35 includes an outlet 23b projecting substantially in the center of the upper surface thereof, and two electrode rod exposed holes 35a and 35b arranged on the sides of the outlet 23b, respectively.

As described above, the outlet 23b is a hole for connecting to the outlet connection port 18c of the head portion 18 and allowing hot water in the electrolytic portion 23 to flow out into the head portion 18.

The electrode rod exposed holes 35a and 35b are holes for exposing the positive electrode rod 31a and the negative electrode rod 31b of the electrode body 31, which will be described later, to the outer surface of the electrolytic portion 23, and the inner circumference thereof is inside the electrolytic portion 23.

The electrode body 31 is composed of a plurality of electrode plates 36, a lock body 37 that integrally binds the plurality of electrode plates 36, a positive electrode rod 31a, and a negative electrode rod 31b.

The electrode plate 36 is a strip-shaped metal flat plate for contacting hot water flowing into the electrolytic unit 23 from the inflow port 23a to perform electrolysis, and in the present embodiment, five electrode plates 36a to 36e are provided. There is. The thickness of the electrode plate 36 is 0.1 mm to 1.0 mm, and a titanium plate plated with platinum is used as the material.

Further, one end side of each electrode plate 36 in the longitudinal direction, and in the present embodiment, the upper position of each electrode plate 36 in FIG. 8 is provided with an ear piece portion 38 formed in a wide shape toward one side in the lateral direction. There is. The ear piece portion 38 is a portion for electrically connecting to the positive electrode rod 31a or the negative electrode rod 31b, and the five electrode plates 36a to 36e are alternately turned upside down so that the electrode plates 36a, The ear pieces 38 of the three electrode plates 36 of 36c and 36e are aligned to the right side in FIG. 8 to form a negative electrode rod connecting portion 38a in a protruding state, and the ears of the two electrode plates 36 of the electrode plates 36b and 36d. The single portion 38 is aligned to the left side to form a positive electrode rod connecting portion 38b so as to be connected to the negative electrode rod 31b and the positive electrode rod 31a, respectively.

Further, the electrode body 31 is configured by binding the electrode plates 36a to 36e with the lock body 37. FIG. 9 is an explanatory diagram showing a binding structure formed by the lock body 37.

As shown in FIG. 9, the lock body 37 is composed of a male lock piece 39 and a female lock piece 40.

The male lock piece 39 is a member formed in a substantially U-shape in a side view, and includes a back plate 39a and two locking claws 39b.

On the surface of the back plate 39a facing the side surface of the electrode plate 36, groove portions 39c of a plurality of rows (five rows corresponding to the five electrode plates 36a to 36e in this embodiment) are engraved, and the groove portions 39c are engraved. The ridges formed between the rows are configured to function as the spacer 39d. That is, by fitting the side surfaces of the electrode plates 36a to 36e into the groove portions 39c, the gaps between the electrode plates 36a to 36e can be held at predetermined intervals by the spacers 39d.

On the other hand, the female lock piece 40 includes a back plate 40a and two sleeve plates 40b. The back plate 40a of the female lock piece 40 also forms a plurality of groove portions 40c and a spacer 40d in the same manner as the back plate 39a of the male lock piece 39 described above, and the gaps between the electrode plates 36a to 36e are spaced apart from each other at predetermined intervals. It is possible to hold it in.

Further, each of the sleeve plates 40b is formed with a locking hole 40e. The spacer 40d is a hole for locking the locking claw 39b of the male lock piece 39, and a plurality of electrode plates 36a to 36e are sandwiched between the male lock piece 39 and the female lock piece 40 to be locked. As a result, it is possible to bind the electrode plates 36a to 36e while maintaining the gaps between the electrode plates at predetermined intervals. In particular, in the present embodiment, the gap between the electrode plates 36a to 36e is 0.3 mm to 1.0 mm, and a narrow laminated electrode structure having an internal flow path divided into layers having an extremely narrow width is configured.

This narrow laminated electrode structure is one of the notable points in the shower head A according to the present embodiment, and the same flowing water can be circulated in the flow process while allowing the entire amount of the large flow of flowing water supplied per unit time to be circulated. It is useful for electrolyzing to generate high-concentration electrolytic hydrogen water with low electric power.

As shown in FIGS. 8 and 9, the amount of dissolved hydrogen in the hot water flowing in the gap flow path layered by the electrode plates 36a to 36e increases as the gap narrows.

That is, the flow rate of hot water relatively increases with the narrowing of the gap, and the effect of sufficiently dissolving the generated hydrogen in the running water occurs (effect of increasing the hydrogen dissolution efficiency).

As a result, when the electrolytic hot water is viewed from the viewpoint of electrolytic hydrogen water, the dissolved hydrogen amount of about 50 ppb or more can be maintained even if the flowing water amount is 7 L / min or more, and excellent active oxygen scavenging ability is imparted. Is possible.

On the other hand, when the gap is widened, the water flow rate is relatively low, and the amount of water dissolved in the generated hydrogen is reduced. That is, if the gap is made larger than 1.0 mm, hydrogen water in a hydrogen-saturated state is locally generated, 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, by narrowing the gap to 1.0 mm or less as in the present embodiment, it is possible to secure a dissolved hydrogen amount of 50 ppb or more even if the flowing water amount is 7 L / min or more. Further, when the gap is widened, the voltage becomes high and the power consumption required for electrolysis increases. Therefore, from the viewpoint of power reduction, it is preferable to narrow the gap to 1.0 mm or less.

In this way, the gap flow path whose gap is divided into 1.0 mm or less by a plurality of electrode plates 36a to 36e effectively electrolyzes the entire amount of water even if the flow rate is as large as 7 L / min or more. Therefore, electrolytic hydrogen water with a high amount of dissolved hydrogen can be stably produced.

As shown in FIG. 8, the positive electrode rod 31a is a conduction rod connected to the electrode plates 36b and 36d that function as positive electrode plates, and the positive electrode rod 31a is an electrode rod of the lid portion 30 when the electrolytic portion 23 is assembled. It is exposed from the exposed hole 35a and functions as the anode terminal 23d of the electrolytic unit 23.

Like the positive electrode rod 31a, the negative electrode rod 31b is also a conduction rod connected to the electrode plates 36a, 36c, 36e that function as the negative electrode plate, and the negative electrode rod 31b is the lid portion 30 when the electrolytic portion 23 is assembled. It is exposed from the electrode rod exposed hole 35b of the above and functions as the cathode terminal 23e of the electrolytic unit 23.

Further, a male screw is formed at the tip of each of the electrode rods 31a and 31b, and the lid portion 30 and the electrode body 31 are integrated by screwing the retaining member 30a at the time of assembling the electrolytic portion 23. It is configured as follows.

The case body 32 is provided with a bottomed tubular body portion 32a that is gently narrowed downward in FIG. 8, and the inside thereof is an electrode body accommodating space 32c for accommodating the electrode plate 36.

Further, an inflow port 23a is provided at the bottom of the cylinder body portion 32a so that hot water can flow into the cylinder body portion 32a.

Further, a flange 32b is formed on the peripheral edge of the upper opening of the cylinder body portion 32a toward the outside in the radial direction. The flange 32b is a portion for watertightly closing the upper opening of the case body 32 with the lid portion 30 by the connecting ring 33 described below.

The connecting ring 33 is a ring-shaped member, and a female screw portion 33a screwed with the male screw portion 34a of the lid portion 30 is formed on the inner peripheral surface.

Further, an inner flange 33c is provided on the inner edge of the lower end of the hole 33b of the connecting ring 33 inward in the radial direction. When assembling the electrolytic portion 23, the inner flange 33c is formed by screwing the female screw portion 33a and the male screw portion 34a with the case body 32 inserted through the hole portion 33b, whereby the inner flange 33c is used to form the case body 32. This is a portion for crimping the flange 32b to the lid portion 30 to ensure a watertight state.

The electrolytic unit 23 having such a configuration forms a space portion 47 as shown in FIG. 5 in relation to the outer cylinder 22 constituting the stem portion 17.

In this space 47, vibrations generated when the user U uses the shower head A and vibrations generated when hot water flows in the shower head A efficiently propagate to the electrode body 31 in the electrolytic unit 23. It is a part that functions as a vibration allowable means for allowing the vibration of the electrolytic unit 23 itself.

During electrolysis, innumerable bubbles are generated in the gaps between the electrode plates 36a to 36e inside the electrolysis unit 23, and many bubbles are removed from the surface of the electrode plates 36a to 36e together with the flow of the electrolytic hot water. However, some bubbles may remain attached to the surfaces of the electrode plates 36a to 36e as they are, and the electrolysis efficiency may decrease.

In this respect, in the shower head A provided with the space portion 47, when the space portion 47 functions as a vibration allowable means and the electrolytic portion 23 is fixed to the entire inside of the outer cylinder 22 without the space portion 47. In comparison, the electrode plates 36a to 36e vibrate efficiently, and the bubbles in the adhered state are efficiently removed, so that the decrease in electrolytic efficiency can be suppressed as much as possible.

As shown in FIGS. 4 to 6, the head portion 18 is a member for discharging hot water flowing from the outlet connection port 18c through the electrolytic portion 23 from the sprinkler plate 19, and the inside thereof is as shown in FIG. The partition wall 41 is divided into a region serving as a flow path for hot water and a non-immersed region.

The outlet connection port 18c is a flow path for guiding the hot water flowing into the head portion 18 to the water chamber 42, and the communication connecting portion of the electrolytic portion 23 with the outlet 23b has substantially the same diameter as the outer diameter of the outlet 23b. The inner diameter is set to the inner diameter of the above, and the packing 23f is brought into close contact with the packing 23f to maintain watertightness.

The water chamber 42 is a portion for storing a certain amount of hot water flowing in from the outlet connection port 18c and buffering the water flow. The water chamber 42 is a substantially columnar space, and a sprinkler plate 19 is provided at a portion corresponding to the bottom surface thereof so that hot water can be sprinkled.

Further, the water chamber 42 is also a space for balancing the weight of the shower head A when it is used in relation to the power storage body 16.

Assuming a plane M separating the plane M, the center of gravity P1 of the water chamber 42 is located on the water discharge side and the center of gravity P2 of the power storage body 16 is located on the dorsal side of the plane M.

With such a configuration, when the user is using the shower head A while holding the stem portion 17, the weight balance of the shower head A can be kept good, and the weight of the power storage body 16 can be reduced. It is possible to obtain a shower head A having a good usability without making it feel as much as possible.

Further, as shown in FIG. 5, a waterproof lid 43 is fitted in the non-inundation region separated by the partition wall 41, and the main body side control unit 70 is arranged inside the non-inundation space 44 as a non-inundation space 44.
