However, it has not been easy to prevent these problems, which has been a problem in the past. ing.
Moreover, in urinals, urine stones adhere to the inside of the pipe and narrow the drainage channel, adhere to the surface of the toilet bowl, impair the appearance, and become a hotbed for bacterial growth and give off odors. It has become.
Furthermore, urine stones once attached to the surface of the toilet bowl cannot be removed unless they are rubbed strongly with a brush. For this reason, it is difficult to remove these urine stones by ordinary cleaning, and it is necessary to request a specialized trader, resulting in a large burden.

  In order to solve these problems, conventionally, as described in Patent Document 1, for example, hydroelectric power generation is performed using a water flow of washing water, and silver is generated using electric energy obtained by the power generation.

In the silver electrolyzed water spouting device of the present invention configured as described above, there are a main channel through which the wash water flows in the electrolytic cell, and a branch channel through which the wash water flows from the main channel and returns to the main channel after the diversion. Since a pair of electrodes, which are formed and at least the anode electrode is a silver electrode that generates silver ions, are arranged in this branch channel, the water in the branch channel is generally compared to the water flow in the main channel A boundary layer is formed between the electrodes by passing between the electrodes in a state of low flow velocity and less turbulence. This boundary layer prevents silver ions generated at the electrode from reacting with chlorine ions contained in the water in the diversion channel to generate silver chloride, and maintains the state of silver ions. The production efficiency of silver ions in can be improved. Moreover, since the power consumption of the electrode is suppressed to obtain a predetermined amount of silver ions, the consumption of the electrode can be suppressed.

As a result, the water in the branch flow path is rectified by the inflow side end of the electrode holding member, and passes between the electrodes in a flow state in which the flow velocity is smaller and less disturbed than the water flow in the main flow path. In addition, a boundary layer is formed between the electrodes, and this boundary layer suppresses the generation of silver chloride by reacting the silver ions generated at the electrode with the chlorine ions contained in the water in the distribution channel. Therefore, the silver ion generation efficiency in the electrode can be improved.

It is DD sectional drawing of an electrode holding member, FIG. 6: is EE sectional drawing of the electrode holding member of the silver electrolyzed water discharging apparatus by 1st Embodiment of this invention shown in FIG.
As shown in FIGS. 4 to 6, the silver electrodes 12a and 12b are embedded and held in the electrode holding members 14a and 14b, respectively, and hold the silver electrodes 12a and 12b of the electrode holding members 14a and 14b.

Yes.
Here, the above-mentioned “running section” refers to the water flow W2 on the surface 12c of the silver electrodes 12a and 12b when the cleaning water flows between the silver electrodes 12a and 12b of the electrode holding members 14a and 14b of the branch channel 2b. It means a region where turbulence is reduced to a flow with less turbulence such as laminar flow. Further, the run-up section 22 is located in the branch flow path 2b so that the flow path shape of the water flow W2 does not change, other than the area of the surface 14c of the electrode holding members 14a and 14b on the side where the silver electrodes 12a and 12b are disposed. It also includes a region extending in a predetermined direction so as to be flush with the region of the surface 14c of the electrode holding members 14a and 14b.

Below, the control apparatus 4 of the silver electrolyzed water discharging apparatus 1 is demonstrated concretely.
As shown in FIG. 1, the control device 4 of the silver electrolyzed water discharge device 1 according to the present embodiment includes a control unit 24, an on-off valve electromagnetic drive unit 26, a current supply unit 28, a power supply unit 30, and a sensor 32. ing.
The control unit 24 is configured to control the other circuit elements 26, 28, 30 and 32.
For example, the on-off valve electromagnetic drive unit 26 is configured to drive the on-off valve 6 by outputting a voltage to the on-off valve 6 when adjusting the opening degree of the on-off valve 6.
The current supply unit 28 is configured to elute silver ions Ag ⁺ from the silver electrode 12 by supplying current to the silver electrode 12.

The sensor 32 is disposed, for example, above or in front of the flush urinal 8 and configured to detect the presence of the user by infrared rays or the like. The control unit 24 operates the on-off valve electromagnetic drive unit 26 based on the detection information from the sensor 32 to adjust the opening degree of the on-off valve 6, so that flush water is appropriately flowed into the flush toilet 8. ing.

7 is a diagram showing a detailed configuration of the current supply unit 28 shown in FIG.
As shown in FIG. 7, the current supply unit 28 includes an electrical conductivity detection circuit 34, a constant current circuit 36, and a polarity inversion circuit 38.
In order to enhance the sterilizing effect of the washing water and at the same time prevent the toilet from being discolored by the washing water, it is desirable that the addition amount of silver ions Ag ⁺ is within a predetermined range, and depending on the electric conductivity of the tap water W, It is necessary to adjust the current supplied to the silver electrode 12. For this reason, the electrical conductivity detection circuit 34 is configured to detect the electrical conductivity of tap water.
The detection of the electrical conductivity of water is performed, for example, by passing a constant current between the electrodes of the silver electrode 12 by the constant current circuit 36 and measuring the voltage between the electrodes at that time by the electrical conductivity detection circuit 34. It has become.

The constant current circuit 36 is configured to control and output an optimum current value for eluting silver ions Ag ⁺ .
Further, the polarity inversion circuit 38 is configured to appropriately invert the polarity of the current output to the silver electrode 12. Note that the polarity reversal is performed, for example, every time the cleaning water is generated so that the consumption of both the silver electrodes 12a and 12b accompanying the elution of the silver ions Ag ⁺ is equalized.

Moreover, about the addition amount of silver ion Ag ⁺ with respect to the wash water sent to the flush toilet 8, generally, if too little, sufficient sterilization effect will not be acquired, but if too much, the power consumption regarding a silver electrode will become large, There is a problem that the consumption of the silver electrode becomes severe. Furthermore, adhering silver ions Ag ⁺ silver chloride AgCl which the amount is too large silver ions Ag ⁺ simultaneously with generation of the pottery surface of the toilet, there is a problem that discoloration such darkening occurs. In the present embodiment, in consideration of such a problem, the amount of silver ion Ag ⁺ added to the washing water in the electrolytic cell 2 is configured to be in the range of 1 to 50 ppb.

Next, the operation (action) of the first embodiment of the present invention will be described.
FIG. 8A shows water in a state before the electrode holding member 14 including the silver electrode 12 is arranged in the electrolytic cell 2 in the electrolytic cell 2 of the silver electrolyzed water discharge device 1 according to the first embodiment of the present invention. FIG. 8B is a schematic cross-sectional view showing a flow, and FIG. 8B shows an electrode holding member 14 including a silver electrode 12 in the electrolytic cell 2 in the electrolytic cell 2 of the silver electrolyzed water discharger 1 according to the first embodiment of the present invention. It is a schematic sectional drawing which shows the flow of the water in the state arrange | positioned in.
First, as shown to Fig.8 (a), in the silver electrolyzed water discharging apparatus 1 of the state before arrange | positioning the electrode holding member 14 containing the silver electrode 12 in the electrolytic cell 2, the water supply path 3 in the electrolytic cell 2, Since the electrolytic cell 2 is formed between the drainage channel 5 and the drainage channel 5, the main channel region S1 shown inside the dotted line in FIG. 8A is slightly in the electrolytic cell 2 from the water supply channel 3 to the drainage channel 5. It is formed to spread. In the main channel region S1, the tap water W that has flowed into the electrolytic cell 2 from the water supply channel 3 flows out to the drainage channel 5 while maintaining a high flow rate.
On the other hand, a main channel outer region S2 is formed outside the main channel region S1. In the main flow path outside region S2, a flow swirled by the separation of the flow, that is, a flow with a very low flow velocity flows backward.

Next, as shown in FIG. 8B, in the silver electrolyzed water spouting device 1 in a state where the electrode holding member 14 including the silver electrode 12 is disposed in the main flow path outside region S2, the inside of the electrolytic cell 2 from the water supply channel 3 The tap water W that flows into the water flow W1 flows through the main flow path 2a and flows out to the drainage channel 5, and the water flow W1 has a high flow rate, and is divided from the downstream side of the main flow path 2a to the branch flow path 2b, compared with the flow speed of the water flow W1. The water is diverted to the water flow W2 flowing through the diversion channel 2b at a very small flow rate.
The water flow W1 of the main flow path 2a passes through the outside of the electrode holding member 14 without passing between the electrode holding members 14a and 14b including the pair of silver electrodes 12a and 12b arranged in the electrolytic cell 2. The main stream flows to the drainage channel 5 on the downstream side.
On the other hand, the water flow W2 of the branch flow path 2b flows in a direction opposite to the direction of the water flow W1 of the main flow path 2a at a very low flow rate compared to the flow rate of the water flow W1, and the running sections 22a and 22c of the electrode holding members 14a and 14b. , 22d and slowly passes between the silver electrodes 12a, 12b.
A voltage is applied between the silver electrodes 12a and 12b. For example, when the silver electrode 12a acts as an anode and the silver electrode 12b acts as a cathode, silver ions Ag ⁺ are generated from the silver electrode 12a on the anode side. Then, these silver ions Ag ⁺ are released into the water flow W2 between the silver electrodes 12a and 12b (details will be described later). The water stream W2 ′ containing these silver ions Ag ⁺ merges with the water stream W1 in the main channel 2a again on the downstream side of the branch channel 2b.
A water flow W2 ′ joined to the water flow W1 flows through the drainage channel 5 and is supplied to the flush toilet 8. When washing water of the water flow W2 ′ containing silver ions Ag ⁺ flows into the flush urinal 8, the silver ions Ag ⁺ contained in the washing water are used for sterilization and sterilization in the flush urinal 8.

Next, the silver ions Ag ⁺ generated between the silver electrodes 12a and 12b will be described in detail.
FIG. 9 is a schematic view showing a state in which silver ions Ag ⁺ are generated in the silver electrode 12. As shown in FIG. 9, the water flow W2 in the branch flow path 2b is rectified by passing through the running sections 22a, 22c, and 22d of the electrode holding members 14a and 14b, so that at least between the silver electrodes 12a and 12b. The flow is less turbulent like laminar flow. At this time, silver ions Ag ⁺ are eluted by silver electrolysis at the silver electrode 12a on the anode side.
In addition, the water flow W2 that has passed through the run-up sections 22a, 22c, and 22d flows between the silver electrodes 12a and 12b at a flow velocity that is much smaller than the flow velocity of the water flow W1 in the main flow path 2a. , 12b, a boundary layer BL having a certain thickness is formed.
Here, the “boundary layer” is a region near the surface of the object, and means a region of a flow with a small flow velocity and a small disturbance such as a laminar flow region.

Further, between the silver electrodes 12a and 12b, the water flow W2 flows with a low turbulence and at a very low flow rate, so that the chlorine ions Cl ⁻ contained in the water flow W2 are in the direction of the arrow A in FIG. The chlorine ion supply amount per unit time that moves and is supplied between the silver electrodes 12a and 12b is suppressed as shown in FIG. As a result, in the water flow W2 between the silver electrodes 12a and 12b, the production of silver chloride AgCl due to the reaction between silver ions Ag ⁺ and chlorine ions Cl ⁻ is suppressed, and the state of silver ions Ag ⁺ is maintained.

Further, it is considered that the boundary layer BL formed in the vicinity of the silver electrodes 12a and 12b is thicker as the flow velocity of the water flow W2 is smaller and thinner as the flow velocity of the water flow W2 is larger and approaches turbulent flow.
In the present embodiment, the water flow W2 flows between the silver electrodes 12a and 12b at a very low flow rate in a state of laminar flow with little turbulence, so that the thickness of the boundary layer BL is kept moderate. ing. Therefore, the boundary layer BL suppresses the movement of the chlorine ions Cl ⁻ as shown in the direction of the arrow B in FIG. 9 to be supplied to the silver electrode 12a side of the anode, and the silver ions Ag ⁺ and the chlorine ions Cl ^Since the production of silver chloride AgCl due to the reaction with-is suppressed, the state of silver ions Ag ⁺ is maintained.

According to the silver electrolyzed water discharging apparatus 1 according to the first embodiment of the present invention described above, a set of electrode holding members including a set of silver electrodes 12a and 12b in the main flow path outside region S2 having a small flow velocity in the electrolytic cell 2. 14a and 14b are arranged to form a diversion channel 2b, and a portion of the wash water W2 before being supplied to the flush urinal 8 is diverted between the silver electrodes 12a and 12b of the diversion channel 2b. The generation efficiency of Ag ⁺ can be greatly improved.
Moreover, according to the silver electrolyzed water discharging apparatus 1 of this embodiment, the water flow W2 of the branch flow path 2b becomes a flow with less turbulence such as a laminar flow by the running sections 22a, 22b, 22c, and 22d of the electrode holding member 14, It passes between the silver electrodes 12a and 12b at a very small flow rate compared with the flow rate of the water flow W1 of the main flow path 2a. For this reason, the flow rate of the water flow W2 containing the chlorine ions Cl ⁻ is limited. In addition, the boundary layer BL formed in the vicinity of the silver electrodes 12a and 12b reduces the absolute amount of chlorine ions Cl ⁻ that react with the silver ions Ag ⁺ between the silver electrodes 12a and 12b, thereby generating silver chloride AgCl. Is suppressed. Therefore, the silver ion Ag ⁺ eluted by silver electrolysis at the silver electrode 12a on the anode side is maintained in the state of silver ion Ag ⁺ because the loss due to the generation of silver chloride AgCl is suppressed, and thus the silver ion Ag ⁺ is maintained. The production efficiency of can be improved.
Furthermore, according to the silver electrolyzed water discharging apparatus 1 of this embodiment, the power consumption by silver electrolysis accompanying the production | generation of predetermined amount of silver ion Ag ⁺ can be suppressed. Moreover, since the consumption of the silver electrode is suppressed, the useful life of the silver electrolytic cell can be greatly extended.
Moreover, according to the silver electrolyzed water discharging apparatus 1 of this embodiment, the addition amount of silver ion Ag ⁺ in the wash water supplied to the flush urinal 8 can be set appropriately, and the flush urinal 8 and their piping A sufficient bactericidal effect can be obtained.
Furthermore, according to the silver electrolyzed water discharging apparatus 1 of this embodiment, since the electrode holding member 14 is disposed substantially in parallel with the side wall 16 of the electrolytic cell 2 formed in a quadrangular shape, the electrolytic cell 2 is tubular. Compared with the case where the water flow is formed, the water flow W2 flowing into the branch channel 2b becomes uniform, and the disturbance of the water flow between the silver electrodes 12a and 12b can be suppressed.

According to the modified example of the silver electrolyzed water spouting device 1 according to the first embodiment of the present invention configured as described above, when the water flow W2 flows into the run-up section 42a on the upstream side of the electrode holding member 40, the round shape The inflow end 44 can rectify the water flow W2 to prevent turbulence.
Therefore, the distance between the upstream running section 42a and the downstream running section 42b of the electrode holding member 40 can be set shorter than the running sections 22a and 22b of the first embodiment.
