Description

  The present invention relates to a toilet flushing water generating apparatus, and more particularly, to a toilet flushing water generating apparatus capable of generating flush water containing silver (Ag) ions and flowing it to a flush toilet or the like.

  The flush toilet is manually washed by the user's button operation, etc., or when a person stands in front of the toilet and the use of the toilet is finished, tap water such as tap water and middle water is automatically flowed. Cleanliness is maintained by automatic cleaning. However, it is not easy to prevent “water stains” and “slime” from accumulating in the toilet bowl and the drain pipe and preventing the generation of odors by simply flowing tap water. Also, in small toilets, “urine stone” adheres to the inside of the pipe and narrows the passage of drainage, or adheres to the surface of the toilet and impairs its appearance, creating a hotbed for bacterial growth and giving off odors. become. Once attached, the urine stone is difficult to remove by normal cleaning, and cannot be removed unless it is rubbed strongly with a brush or the like. For this reason, it is necessary to request a specialist to remove urine stone, which is a heavy burden.

  In response to this problem, the present inventors have invented a sterilization apparatus that generates electric power using the flow energy of the washing water and contains silver ions in the washing water using this electric energy (for example, Patent Document 1 and Patent Document 2).

According to these inventions, no commercial power source such as a household 100 volt power source is required as an electrical energy source, no countermeasures against power outages or electric shocks are required, and water ions, slime, Generation of urinary stones and the like can be suppressed, and a toilet sterilizer with low running cost can be provided.

  However, since the washing water flowing in the flush toilet has a role of drainage washing, a large amount of energy cannot be subtracted from the water pressure of the washing water as a power generation amount, and the power generation amount is limited. On the other hand, there is an optimum range for the concentration of silver ions to be added to the washing water. Therefore, in order to stably generate washing water containing silver ions in the optimum concentration range using a limited amount of power generation, the efficiency of silver ion generation is increased and the power of various circuit elements is increased. A device for consumption is required. Furthermore, when combined with a human body detection type automatic cleaning system, it is necessary to perform control so that the limited power generation amount can be effectively utilized.

  The present invention has been made based on recognition of such a problem, and an object of the present invention is to provide a toilet flushing water generation device using silver ion electrolyzed water that uses power generation by washing water and can also perform operations such as automatic washing. There is to do.

In order to achieve the above object , according to one aspect of the present invention , there is provided power generation means for generating electric power by a flow of washing water, and at least one of a pair of electrodes containing silver, and the electrodes are immersed in the washing water. In this state, the first power utilization means that allows silver ions to be released into the washing water by energizing the pair of electrodes, and passing only a part of the washing water between the pair of electrodes. The shunting means, the second power using means for consuming power, the first mode using only the second power using means, and the power generated by the power generating means to the first power using means and a second mode utilizing supplied with said first power utilization means and said second power utilization means simultaneously, and a control means which enables switching, wherein the shunt means, the wash water The pair of electric power provided in the flowing pipe A first flow path, the toilet flush water generating apparatus characterized by having, a second flow path that is not sandwiched by the pair of electrodes are provided which are sandwiched by.
According to another aspect of the present invention, the power generation means for generating electric power by the flow of the washing water, and at least one of the pair of electrodes containing silver, the electrode being immersed in the washing water A first power utilization means capable of discharging silver ions into the washing water by energizing between the pair of electrodes; and a diversion means for allowing only a part of the washing water to flow between the pair of electrodes. A second mode that consumes power, a first mode that uses only the second power usage unit, and a power generated by the power generation unit while supplying the first power usage unit. Control means capable of switching between a second mode in which the first power use means and the second power use means are simultaneously used, wherein the pair of electrodes are pipes through which the wash water flows. In the cross section, the flow velocity is smaller than the average flow velocity Toilet bowl flushing water generation apparatus, characterized in that provided in the portion is provided.

According to the said structure, by providing a diversion means, the quantity of the chlorine ion supplied to an electrode can be suppressed, and the production | generation efficiency of silver ion can be raised. As a result, silver ions can be reliably generated by the limited power generated by the power generation means. In addition, by increasing the generation efficiency of silver ions, it is possible to suppress the consumption of the electrodes and extend the life. Furthermore, the pressure loss of the washing water can be reduced by reducing the amount of water flow between the electrodes by the diversion. As a result, the power generation amount of the power generation means can be increased, and the physical cleaning effect of the toilet can be maintained. Furthermore, by switching between the first mode and the second mode, it is possible to efficiently use the generated power limited by the power generation means by avoiding the loss that occurs during power storage.
The diversion unit includes a first flow path provided between the pair of electrodes and a second flow path not sandwiched between the pair of electrodes, which are provided in a pipe through which the cleaning water flows. If so, the apparatus can be made compact and the electrode can be easily replaced.
Further, if the pair of electrodes is provided in a section where the flow velocity is smaller than the average flow velocity in the cross section of the pipe through which the washing water flows, the distribution of the flow velocity in the pipe is used to The amount of water flow can be effectively reduced, and the apparatus can be made compact.

Here, it is further provided with a power storage unit capable of storing the power generated by the power generation unit, and the second power utilization unit in the first mode is supplied with power from the power storage unit, The power utilization means can be operated even when the power generation means is not operating.
Or a power storage unit capable of storing the power generated by the power generation unit, wherein the second power utilization unit supplies power from at least one of the power generation unit and the power storage unit in the first mode. If the power generation means is not operating, it is possible to operate the second power utilization means by supplying power from the power storage unit, and when the power generation means is operating, The second power utilization unit can be operated by supplying power from only the power generation unit, from the power generation unit and the power storage unit, or from only the power storage unit.

  In the first mode, if the power generated by the power generation means is stored in the power storage unit in the first mode, the control means can generate and store power during a cleaning process that does not generate silver ions. The drive power supply for the second power utilization means can be secured.

  In addition, if the cross-sectional area of the flow path of the cleaning water formed between the pair of electrodes is substantially the same from one end to the other end of the pair of electrodes, Therefore, it is sufficient to design the water flow mainly by paying attention to the ratio between the cross-sectional area of the water flow between the electrodes and the cross-sectional area of the pipe, and the design is reliable and easy. Furthermore, there is no influence of the blockage of the water flow between the electrodes.

  Further, the flow path of the washing water formed between the pair of electrodes has a throttle portion between one end of the pair of electrodes and the other end, without changing the electrode interval, etc. Since the water flow resistance between the electrodes can be increased, the water flow rate can be reduced without changing the electrode design conditions.

  For example, if the pipe through which the cleaning water flows is provided with a bent portion and the pair of electrodes are provided on the inner peripheral side of the bent portion, the passage between the electrodes is not changed without changing the electrode spacing. Since the water resistance can be increased, the water flow rate can be reduced without changing the electrode design conditions.

  According to the present invention, silver ion-containing water having a high bactericidal effect is generated by a self-power generation method without using a commercial power source of 100 volts or the like and without having to replace a primary battery or a secondary battery. Can be flushed in the toilet bowl. In addition, even when a primary battery, a secondary battery, or the like is provided as an auxiliary, the frequency of replacement can be greatly reduced. In addition, convenient additional functions such as automatic cleaning can be realized at the same time. Moreover, by increasing the generation efficiency of silver ions, it is possible to extend the life of the silver electrode and reduce maintenance such as electrode replacement.

  That is, according to the present invention, it is possible to provide a toilet flushing water generating apparatus that is highly convenient and can maintain the toilet in a sanitary manner while achieving energy saving and resource saving.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Drawing 1 is a mimetic diagram showing the example of the toilet bowl washing water generating device concerning an embodiment of the invention. That is, the toilet flushing water generating apparatus according to the present embodiment includes a circuit group 100 including a control circuit, a rectifier circuit, and the like, an on-off valve 200, a flow dividing unit 300, a silver electrolytic cell 400, and a power generating unit 500. In the present specification, the silver electrolytic cell 400 is appropriately referred to as “first power utilization means”, and each circuit element included in the circuit group 100 is appropriately referred to as “second power utilization means”.

  The tap water W such as tap water and middle water is opened and closed by an on-off valve 200 including a plunger-type latching solenoid valve, for example. A diversion means 300 is provided downstream of the on-off valve 200, and the tap water flow path is branched into a silver electrolysis tank 400 and a power generation means 500. The water that has passed through the silver electrolysis tank 400 and the power generation means 500 joins again and is supplied to the flush toilet 600 as washing water.

FIG. 2 is a schematic diagram showing a unit including the diversion unit 300, the silver electrolytic cell 400, and the power generation unit 500 in this specific example. That is, FIG. 4A is a perspective view showing the appearance, and FIG. 4B is a cross-sectional view showing the internal structure.
As shown in FIG. 5A, this unit includes integral connection terminals 410a and 410b protruding from the side surface and a generator 510. When the inside is seen, the flow dividing means 300 has a flow path branched into two, and the silver electrodes 420a and 420b of the silver electrolytic cell 400 are provided facing each other in the flow path. These silver electrodes 420a and 420b are connected to connection terminals 410a and 410b, respectively. When a current is passed between the connection terminals 410a and 410b, silver (Ag) ions are eluted from the silver electrode on the anode side by an electrolysis reaction and added to tap water.

On the other hand, a water wheel 520 is provided in the other branched flow path. The water turbine 520 is rotated by the water flow of the tap water W, and the rotational motion is transmitted to the drive shaft of the generator 510. Then, the kinetic energy of tap water is converted into electric energy, and electric power is generated.
The water that has passed through each of the silver electrolysis tank 400 and the power generation means 500 joins again downstream, and is supplied to the flush toilet as washing water.
Referring back to FIG. 1 again, the second power utilization unit 100 includes circuits such as a control unit 110, an on-off valve electromagnetic drive unit 120, a current supply unit 130, a power storage unit 140, a rectification unit 150, and a sensor 160. Elements are provided.

These circuit elements will be described. First, the control unit 110 has a role of managing and controlling operations of other circuit elements. The on-off valve electromagnetic drive unit 120 drives the on-off valve 200 by outputting a voltage for opening the on-off valve 200, for example.
The current supply unit 130 supplies a current for elution of silver ions to the silver electrolytic cell 400. The power storage unit 140 has a role of storing the power generated by the power generation unit 500, and includes, for example, a voltage conversion circuit and a power storage unit such as a capacitor. The rectifying unit 150 rectifies the AC power generated by the power generation means 500 and converts it into a DC current. The sensor 160 is disposed, for example, above or on the front surface of the flush toilet 600, and detects the presence of the user by infrared rays or the like. Based on the detection information from the sensor 160, the control unit 110 can operate the on-off valve electromagnetic drive unit 120 to open and close the on-off valve 200, thereby allowing flush water to flow through the toilet 600 appropriately.

  FIG. 3 is a schematic view illustrating the configuration of the current supply unit 130. That is, the current supply unit 130 includes, for example, an electrical conductivity detection circuit 132, a constant current circuit 133, and a polarity inversion circuit 134. As will be described in detail later, in order to enhance the sterilizing effect of the washing water and at the same time prevent discoloration of the toilet bowl, it is desirable that the addition amount of silver ions be within a predetermined range. Therefore, it is necessary to adjust the current flowing through the silver electrolytic cell 400 according to the electric conductivity of tap water. For this purpose, the electric conductivity detection circuit 132 has a role of detecting electric conductivity of tap water. The detection of the electric conductivity of water can be performed, for example, by passing a constant current between the electrodes of the silver electrolytic cell 400 by the constant current circuit 133 and measuring the voltage between the electrodes by the electric conductivity detection circuit 132. .

On the other hand, the constant current circuit 133 has a role of controlling and outputting an optimal current value for eluting silver ions.
In addition, the polarity reversing circuit 134 has a role of appropriately reversing the polarity of the current output to the silver electrolytic cell 400. That is, when a direct current is passed between the electrodes 420a and 420b of the silver electrolytic cell 400 illustrated in FIG. 2 to perform electrolysis, a scale such as calcium carbonate adheres to the surface of the cathode (cathode) side electrode. There is a problem that the electrical resistance increases. Note that silver chloride (AgCl) or the like is mainly deposited on the surface of the electrode on the anode (anode) side. Further, as the elution of silver ions, the anode (anode) side electrode is consumed, so it is desirable to evenly consume the pair of electrodes 420a and 420b. Therefore, the polarity inversion circuit 134 appropriately reverses the polarity of the current and outputs it. The reversal of the polarity can be performed, for example, every time cleaning water is generated.

  In the circuit configuration described above, electric power is required to drive the silver electrolytic cell (first power utilization means) 400 and the second power utilization means 110 to 160, respectively. On the other hand, in the present embodiment, the current for operating the silver electrolytic cell (first power utilization unit) 400 is directly supplied from the power generation unit 500 without passing through the power storage unit 140.

FIG. 4 is a schematic view illustrating a path through which power is supplied from the power generation means 500 to the silver electrolytic cell (first power utilization means). That is, in the present embodiment, the electric power obtained in the power generation means 500 is directly supplied to the silver electrolytic cell 400 without being stored in the power storage unit 140.
That is, in the power storage unit 140, it is necessary to appropriately convert the voltage according to the characteristics of the built-in capacitor and the like to accumulate electric power. Accordingly, a certain loss occurs in the process of voltage conversion, accumulation of charge in the capacitor, extraction of the accumulated charge, voltage conversion, and the like.

  On the other hand, according to the present embodiment, the power generated by the power generation means 500 is stored in the power storage unit 140 without supplying the power to the silver electrolytic cell 400 on demand, thereby suppressing the loss, The limited power generation can be efficiently used for the production of silver ions.

  Further, in the present embodiment, circuit elements other than the silver electrolytic cell (first power utilization unit) 400, that is, the second power utilization unit 100 (100 to 160) are used simultaneously with the silver electrolytic cell 400, or The control unit 110 appropriately performs switching so that it can be used by switching.

FIG. 5 is a conceptual diagram illustrating a switching operation executed by the control unit 110.
That is, in mode 1, the silver electrolytic cell (first power utilization means) 400 is not utilized, and only at least one circuit element of the second power utilization means 100 is utilized. For example, as described above with reference to FIG. 1, when the sensor 160 detects the presence of the user and the opening / closing valve electromagnetic driving unit 120 opens the opening / closing valve 200 based on the command of the control unit 110, the silver electrolytic cell 400 is stopped. It can be executed in the state where Further, as will be described in detail later, the electric power necessary for this operation can be supplied from the power storage unit 140.

  On the other hand, in mode 2, the silver electrolytic cell 400 and at least one circuit element of the second power utilization means 100 are utilized simultaneously. For example, when eluting silver ions, as shown in FIG. 4, the second power utilization means such as the rectifying unit 150, the control unit 110, and the current supply unit 130 and the silver electrolytic cell 400 are simultaneously used. Is done. At this time, power to the rectifying unit 150, the current supply unit 130, and the silver electrolytic cell 400 can be directly supplied from the power generation means 500.

  Then, as illustrated in FIG. 5, the control unit 110 performs switching between the mode 1 and the mode 2 as appropriate. In this way, by appropriately switching between mode 1 and mode 2 and executing them, the limited power generated by the power generation means 500 using the tap water flow as an energy source can be used efficiently and added to the addition of silver ions. Thus, various convenient additional functions such as automatic cleaning can be executed.

  Hereinafter, the switching operation between mode 1 and mode 2 executed in the present invention and the proper use of the generated power will be described with specific examples.

FIG. 6 is a timing chart illustrating the operation of mode 1. Hereinafter, this specific example will be described with reference to FIGS. 1 to 5 as appropriate.
For example, when the toilet bowl is provided with an automatic cleaning function, the attached sensor 160 checks the presence / absence of a user at intervals of, for example, 0.5 seconds under the control of the control unit 110. Power at this time can be supplied from the power storage unit 140.

  FIG. 7 is a conceptual diagram illustrating a power supply path to the sensor 160. That is, as represented by the path “A” in the figure, the control unit 110 is operated by the power stored in the power storage unit 140, and at least a part of the power is supplied to the sensor 160 to perform human body detection. Is done.

  Returning to FIG. 6 and continuing the description, when the user approaches the urinal, the sensor 160 detects the human body in step S1. The power at this time is supplied by the path A as shown in FIG. When sensor 160 detects a human body, control unit 110 starts counting a built-in timer. The power supply path at this time is as shown as path “B” in FIG. That is, power is supplied from power storage unit 140 to control unit 110.

  When the timer counts a predetermined time, for example, 5 seconds, the on-off valve 200 is opened in step S2 and “preliminary cleaning” is started. The power supply path at this time is as shown as a path “C” in FIG. 9. Power is supplied from the power storage unit 140 to the control unit 110 and the on-off valve electromagnetic drive unit 120, and the on-off valve 200 is opened. A voltage for maintaining the voltage is output. The electric power from the power storage unit 140 may be supplied to the on-off valve electromagnetic drive unit 120 via the control unit 110, or in parallel to the control unit 110 and the on-off valve electromagnetic drive unit 120. May be supplied.

  Here, “preliminary cleaning” refers to cleaning for preventing dirt from adhering and suppressing the generation of odor by pre-wetting the bowl surface with running water in the toilet bowl prior to use by the user. It is processing. The amount of cleaning water to be flowed in the “preliminary cleaning” can be, for example, about 0.5 liter.

When the cleaning water is flowed by the preliminary cleaning, the power generation means 500 generates electric power. This electric power is supplied to and stored in the power storage unit 140 through the supply path represented as the path “D” in FIG. For example, a capacitor can be used as the power storage unit in the power storage unit 140.
In this case, since the electromotive force of the power generation means 500 may exceed the withstand voltage of the capacitor when the capacitor is fully charged, a switching circuit (not shown) that switches at a predetermined voltage is used, and the output from the power generation means 500 has a predetermined voltage. When exceeding, it is good to consume the output from the electric power generation means 500 with a resistor instead of electrical storage.
When the predetermined flow rate or the predetermined time has elapsed, the on-off valve 200 is closed in step S3. As the on-off valve 200, for example, a so-called latching solenoid valve or the like can be used. This type of on-off valve only needs to supply voltage during opening and closing operations, and does not consume voltage to maintain the open and closed states. Therefore, there is an advantage that power consumption is small.

  Now, during this time, the user starts the small use, and often ends the small use after the preliminary cleaning is completed. When the user finishes the use and leaves the toilet, the sensor 160 does not detect the human body in step S4. The power supply path to the sensor 160 is as shown as path “A” in FIG.

When sensor 160 no longer detects a human body in step S4, control unit 110 starts counting the built-in timer. The power supply path to the control unit 110 is as shown as path “B” in FIG.
When the timer counts a predetermined time, for example, 1 second, the on-off valve 200 is opened in step S5, and the washing water is poured into the toilet bowl and the main washing is started. The flow rate of the main cleaning is appropriately determined according to the type of toilet bowl, the form of the water discharge nozzle, and can be, for example, about 1 to 2 liters. Also during the main cleaning, the electric power generated by the power generation means 500 is stored in the power storage unit 140 through the path indicated by “D” in FIG.
When power is generated by the power generation means 500, in addition to supplying power to the power storage unit 140 or instead of supplying power to the power storage unit 140, part or all of the generated power You may give to the electric power utilization means.

  When the predetermined flow rate or the predetermined time has elapsed, the on-off valve 200 is closed in step S6, and the main cleaning is completed. Thereafter, as described above, the sensor unit 160 detects the presence or absence of the user at intervals of 0.5 seconds, for example. The power supply path at this time is also as shown as path "A" in FIG.

  As described above, in mode 1, for example, operations such as user detection, preliminary cleaning, and main cleaning can be performed based on power supply from the power storage unit 140.

  Next, a specific example of operation in mode 2 will be described.

  FIG. 11 is a timing chart illustrating the operation of mode 2. That is, mode 2 includes the operation of generating wash water to which silver ions are added and flowing it to the toilet bowl. The frequency of flowing the wash water to which silver ions have been added can be appropriately determined according to the use frequency and usage environment of the toilet, the consumption rate of the silver electrode, and the like. For example, it can be set to about 3 to 12 times per day, and for example, it may be allowed to flow after a predetermined time has elapsed since the toilet was last used. Increasing the frequency can easily maintain high cleanliness, but accelerates the consumption of the silver electrode.

  In the case of the specific example shown in FIG. 11, the silver ion water generation sequence is started when two hours have passed since the toilet was last used. That is, the control unit 110 receives power supplied from the power storage unit 140 through the path represented by “B” in FIG. 8 and counts the built-in timer. Then, when 2 hours have passed since the last use, the on-off valve 200 is opened in step S11. The operation of opening the on-off valve 200 is as represented by the path “C” in FIG. 9 and can be executed by the electric power from the power storage unit 140. When the on-off valve 200 is opened in step S11, the conductivity of tap water is measured. That is, as described above with reference to FIG. 3, the electrical conductivity detection circuit 132 measures the electrical conductivity of tap water. The amount of water discharged at this time can be about 2 liters, for example. When about 2 liters of water is allowed to flow, residual urine in the toilet trap can be replaced to some extent, and the sterilization effect by silver ions can be enhanced. The electrical conductivity detection circuit 132 measures the voltage generated by applying a predetermined current to the silver electrodes 420a and 420b of the silver electrolytic cell 400 based on a command from the control unit 110, thereby determining the conductivity. taking measurement. At this time, the current output from the electrical conductivity detection circuit 132 (or the constant current circuit 133) is provided by the power directly supplied from the power generation means 500.

FIG. 12 is a conceptual diagram showing this power supply path. That is, the power generation means 500 starts power generation by opening the on-off valve 200 and flowing tap water. This electric power is supplied to the electric conductivity detection circuit 132 as represented by the path “E”, and is output to the silver electrolytic cell 400 as a detection current. This electric power may be supplied to the current supply unit 130 via the control unit 110, or may be supplied to the control unit 110 and the current supply unit 130 in parallel.
Also here, in the case where power is generated by the power generation means 500, in addition to the power supply to the silver electrolytic cell 400 or in place of the power supply to the silver electrolytic cell 400, a part of the generated power Or you may give all to another electric power utilization means.

  FIG. 13 is a graph illustrating characteristic lines for setting the addition amount of silver ions to 5 ppb. In other words, what is expressed as “control current value” in the same figure represents a current value necessary for setting the addition amount of silver ions to 5 ppb. FIG. 13 also shows voltage and power characteristic lines corresponding to this control current value. As the electric conductivity of tap water is higher, the amount of chlorine ions contained is increased and the elution of silver ions is inhibited, so that the required current value tends to increase.

  Here, the relationship between the electrical conductivity between the electrodes and the current value varies depending on the applied voltage and the structure of the silver electrolytic cell 400. In the case of the specific example shown in FIG. 13, the opposing portions of the silver electrodes 420a and 420b are approximately square of 10 mm × 10 mm, and the distance between the electrodes is 10 mm. The maximum applied voltage was 20 volts (in the case of low-conductivity water), and the maximum current value was 40 milliamperes (in the case of the most dirty medium water).

  Here, in the case of the specific example shown in FIG. 13, the current value is kept constant at 40 mA in the range where the electrical resistance is about 0.38 kΩ or less. The reason for this is that, in the case of water quality where the electrical resistance is less than this, if a current of 40 mA or more is applied to maintain a constant silver concentration, a large amount of silver chloride is produced, and silver chloride is deposited on the toilet surface. This is because “darkness” is a concern. However, it is unlikely that the water resistance in Japan will be less than this electrical resistance.

  The electrical conductivity detection circuit 132 calculates tap water from a voltage between electrodes detected when a predetermined current (for example, 3 mA) is passed, and a predetermined characteristic line, relational expression or table as illustrated in FIG. The electrical conductivity of is calculated. Then, the current value is determined so that the elution amount of silver ions falls within a predetermined range. That is, if the amount of silver ions added is small, the bactericidal effect cannot be obtained sufficiently. On the other hand, if the amount of silver ions added is too large, the silver electrode is consumed very much, and the silver chloride generated simultaneously with the silver ions is removed from the toilet. Discoloration such as “darkening” may occur by adhering to the ceramic surface. According to the results of the study by the present inventors, it was found that the addition amount of silver ions is preferably in the range of 1 to 50 ppb.

  Returning to FIG. 11 again, the explanation will be continued. In step S12, when the on-off valve 200 is closed and the measurement of the electrical conductivity is completed, a predetermined silver is obtained based on the relational expression or table as described above with reference to FIGS. The electrode current value necessary to obtain the ion concentration is determined. This calculation may be executed by the control unit 110, for example, and the power in this case is supplied from the power storage unit 140 along the path “B”.

  When the electrode current value is determined, in step S13, the on-off valve 200 is opened, and at the same time, a current is supplied to the silver electrolytic cell 400 to start discharging the silver ion added water. At this time, the opening operation of the on-off valve 200 is executed by the path “C” shown in FIG. 9, and the energization to the silver electrolytic cell 400 is executed by the path “E” shown in FIG. The water discharge amount of the silver ion-containing water can be, for example, about 4 liters, and the water discharge time is, for example, about 16 seconds in consideration of the pipe resistance of the water discharge nozzle of a normal toilet bowl.

  When the silver ion-containing water is discharged for a predetermined amount of water or for a predetermined time, energization to the silver electrolytic cell 400 is stopped in step S14. Thereafter, the control unit 110 counts the built-in timer. For example, when 1 second elapses, the on-off valve 200 is closed in step S15. In this manner, silver ion water discharge ends. The reason why Step S15 is executed after a predetermined time after Step S14 is that, if silver ion-containing water remains on the surface of the toilet, it causes “darkening”.

  As described above, in mode 2, the first power utilization means (silver electrolytic cell) 400 and the second power utilization means (current supply unit 130, control unit 110, on-off valve electromagnetic drive unit 120, etc.) By simultaneously using, silver ion-containing water can be generated and allowed to flow through the toilet 600.

When the present invention is applied to a toilet bowl, an excellent effect is exhibited in terms of antifouling properties of the toilet bowl and its drain pipe. That is, the mechanism of adhesion of urine stones to the toilet bowl is considered as follows.
When urination is performed in the small toilet, urine adheres to the surface of the small toilet and urine stays in the trap portion in the small toilet. In general, there are many bacteria in a toilet bowl. Urine contains a large amount of urea, but if bacteria are present on the surface of the urinal or in the trapped water, urea is decomposed into ammonia and carbon dioxide by the action of the enzyme urease of the bacteria. If the amount of ammonia produced at this time is large, it will contribute to odor. In addition, when ammonia is generated, it dissolves in the liquid adhering to the surface of the toilet bowl or in the trapped water in the trap part, and the pH of the liquid rises. When the pH rises, calcium ions contained in the liquid adhering to the surface of the small toilet and in the trapped water change into carbonates and phosphates and precipitate as urine stones in the toilet bowl and drain pipe. It will adhere and cause colored stains and clogging.

  On the other hand, in the aspect in which the toilet flushing water generating device according to the present invention is applied to a small toilet, the flushing water containing silver ions having a high bactericidal effect is caused to flow in the small toilet, Can effectively sterilize bacteria. As a result, the cause of urine stone adhesion is eliminated, the toilet bowl is always kept clean and the appearance is not impaired, and narrowing of the sewage passage due to adhesion of urine stone into the pipe is prevented. Moreover, generation of odor due to ammonia or the like is also prevented.

  Further, according to the present invention, by supplying the output of the power generation means 500 on demand as the power for energizing the silver electrolytic cell 400 via the current supply unit 130, the loss in the power storage unit 140 is reduced. Can be avoided and the limited power generation amount can be used efficiently. That is, it is possible to stably generate and flow washing water having a high sterilizing effect without depending on a commercial power source supplied from the outside.

  In addition, among the second power utilization means 100, for example, power for the control unit 110, the on-off valve electromagnetic drive unit 120, etc. is supplied from the power storage unit 140, so that the limited power generation output of the power generation unit 500 is silver electrolyzed. The silver ions can be generated efficiently and reliably by concentrating on the bath 400. Further, the operation of the second power utilization means 100 and the generation of silver ions by the silver electrolytic cell 400 can proceed simultaneously.

  When generating silver ions, the power generation output of the power generation means 500 is used on demand by the route “E” shown in FIG. 12, but the generated power exceeds the power consumption for generating silver ions. In this case, excess power may be stored in the power storage unit 140.

Next, another specific example of the second power utilization means in the present invention will be described.
FIG. 14 is a schematic diagram illustrating a modified example of the toilet flushing water generating apparatus of the present embodiment. In this figure, the same elements as those described above with reference to FIGS. 1 to 14 are denoted by the same reference numerals, and detailed description thereof is omitted.
In this modification, a display unit 170 and an adjustment unit 180 are provided as the second power utilization unit. The display unit 170 displays information related to the output from the power generation unit 500, for example. That is, the control unit 110 can detect the power generation voltage, the number of rotations, and the like of the power generation unit 500, and can display the result of arithmetic processing based on the detection result on the display unit 170. The power supply to the display unit 170 may be directly from the power generation means 500 or may be supplied from the power storage unit 140.
Further, the adjustment unit 180 outputs a signal for controlling the opening degree of the flow rate adjustment valve 210 provided downstream of the on-off valve 200.

  In the present invention, since silver ions are eluted by the limited generated power from the power generation means 500, in order to generate wash water with a stable silver ion concentration (for example, 5 ppb), the instantaneous flow rate of the wash water is set to a predetermined value. It is necessary to adjust to the range. According to the results of the study by the present inventor, for example, in the case of a urinal provided with a spreader type water discharge nozzle that diffuses water discharge over a wide range, the instantaneous flow rate is within a range of 11 to 17 liters per minute. It is desirable. In the case of a rim type small toilet that diffuses water discharged from a “rim” provided around the toilet bowl to the bowl surface, it is desirable that the instantaneous flow rate be within a range of 17 to 25 liters per minute.

  On the other hand, the primary pressure of tap water in a place where a toilet bowl is installed may vary greatly from place to place due to various factors. On the other hand, according to this modified example, the adjusting unit is provided so that the flow rate is measured by providing the display unit 170 and monitoring the output of the power generation means 500, and the optimum flow rate is obtained based on the result. The opening degree of the flow control valve 210 can be adjusted via 180. At this time, it may be displayed on the display unit 170 that the optimum flow rate range has been obtained. In addition, the power of the display unit 170 and the adjustment unit 180 in this modification may be supplied from the power storage unit 140 or directly from the power generation means 500.

FIG. 15 is a schematic diagram illustrating a second modification of the toilet flushing water generating apparatus according to the present embodiment. Also in this figure, the same elements as those described above with reference to FIGS. 1 to 14 are denoted by the same reference numerals, and detailed description thereof is omitted.
In this modification, a notification unit 190 is provided as the second power utilization unit. The notification unit 190 has a role of notifying information on the consumption of the silver electrode. That is, in the toilet flushing water generating apparatus of the present invention, silver ions cannot be generated when the silver electrode of the silver electrolytic cell 400 is consumed. Further, when the silver electrode is consumed, the opposing area of the electrode is reduced and the resistance of the silver electrolytic cell 400 is increased. Therefore, the control unit 110 measures the interelectrode resistance of the silver electrodes 420a and 420b, and if this exceeds a predetermined value, the control unit 110 notifies the notification unit 190 that the electrodes are consumed. As a notification method, for example, a visual display using an LED (light emitting diode) or a liquid crystal, an alarm or an announcement using a voice, or the like can be used. In this case, the notification unit 190 can receive power supply from the power storage unit 140. In addition, if the water is running, power may be supplied directly from the power generation means 500.

  The second power utilization unit that can be used in the present invention has been described above with reference to FIGS. 14 and 15. However, the second power utilization means that can be used in the present invention is not limited to these. That is, as the second power utilization means, in addition to these, for example, a water level sensor (detects the water level of a low tank, a bathtub, etc.), an air mixing means (mixing air into the wash water in a toilet bowl, a hand-washer, a kitchen, etc.) Sound generation means, blower / deodorization means (motor drive, etc.), medicine discharge means (motor or pump drive, etc.), illumination means (LED, lamp, fluorescent lamp, EL, etc.), valve switching (rim water flow) And various types of devices that consume electric power, such as switching of jet water flow).

Next, the effect of the diversion in the toilet bowl washing water generator of the present invention will be described.
That is, in the present invention, as illustrated in FIG. 1 and the like, tap water supplied via a solenoid valve or the like is diverted by the diverting means 300, so that only a part thereof is passed through the silver electrolytic cell 400. . By doing so, silver ions can be generated efficiently even with limited generated power.

  FIG. 16 is a graph showing the relationship between the diversion ratio and the power consumption of the silver electrolytic cell. That is, the horizontal axis of the figure represents the ratio of the flow rate of water passing between the silver electrodes 420a and 420b with respect to the total flow rate of the washing water as a “diversion ratio”, and the vertical axis represents the addition amount of silver ions. Represents the power consumption (milliwatts) of the silver electrolytic cell 400 required to set 5 ppb. Here, the distance between the electrodes of the silver electrodes 420a and 420b was 10 millimeters, the opposing area of the electrodes was 10 millimeters × 10 millimeters, and the total flow rate of water was 25 liters per minute.

  It can be seen from FIG. 16 that the power consumption suddenly decreases when the diversion ratio is about 80%. That is, when the shunt ratio is higher than 80%, the change in power consumption is relatively small even if the shunt ratio is changed. However, when the shunt ratio falls below 80%, the power consumption becomes more noticeable as the shunt ratio is lowered. It turns out that it becomes small. For example, when the shunt ratio is 100 percent, the power consumption is 1315 milliwatts, whereas when the shunt ratio is reduced to 20 percent, the power consumption is 280 milliwatts, which is about 4.7 times lower.

  FIG. 17 is a graph showing the relationship between the shunt ratio and the power consumption of the silver electrolytic cell when the addition amount of silver ions is 4 ppb. Also in this case, it can be seen that the power consumption suddenly decreases when the diversion ratio is about 80 to 60%.

18 and 19 are graphs showing the relationship between the shunt ratio and the power consumption of the silver electrolytic cell when the distance between the electrodes is 5 millimeters. That is, FIG. 18 shows the case where the addition amount of silver ions is 5 ppb, and FIG. 19 shows the case where the addition amount of silver ions is 4 ppb.
As can be seen from FIG. 18, the power consumption is significantly reduced when the diversion ratio is below about 80%. Also in FIG. 19, although the tendency is slightly small, it can be seen that the power consumption decreases when the diversion ratio falls below about 80%.

  20 and 21 are graphs showing the relationship between the shunt ratio and the power consumption of the silver electrolytic cell when the distance between the electrodes is 3 millimeters. That is, FIG. 20 shows the case where the addition amount of silver ions is 5 ppb, and FIG. 21 shows the case where the addition amount of silver ions is 4 ppb. 20 and 21, it can be seen that the power consumption is surely reduced when the diversion ratio is less than about 80%.

  As described above, it can be seen from the results shown in FIGS. 16 to 21 that the generation efficiency of silver ions increases when the flow rate flowing through the silver electrolytic cell 400 is decreased by reducing the diversion ratio. The reason for this is considered to be that the loss due to chlorine ions decreases when the flow rate through the silver electrolytic cell is reduced.

FIG. 22 is a schematic diagram for explaining the improvement of the silver ion production efficiency by the diversion.
That is, silver ions are released from the anode (anode) side electrode. However, negatively charged chlorine ions in the boundary layer near the electrode are attracted to the surface of the anode-side electrode to which a positive voltage is applied. Even if silver ions are released from the silver electrode in this state, they are combined with chlorine ions inside the boundary layer to produce silver chloride (AgCl), and the effect as silver ions cannot be obtained. That is, a state where the loss of eluted silver ions is large is formed.

Further, when the amount of water flowing in the silver electrolytic cell is large, the flow velocity becomes large, so that the flow becomes a turbulent flow or a state closer to a turbulent flow. In this case, since the flow velocity of the main flow increases and the thickness of the boundary layer decreases, the supply (mass transfer) of chlorine ions from the main flow through the boundary layer also increases, and silver chloride is easily generated.
On the other hand, when the amount of water flowing through the silver electrolytic cell is lowered by the diversion, the flow rate in the silver electrolytic cell is decreased, so that the flow becomes a laminar flow or a state closer to a laminar flow. In this case, the flow velocity of the mainstream decreases and the thickness of the boundary layer increases, so the supply of silver chloride (mass transfer) from the mainstream through the boundary layer also decreases, and the production of silver chloride is suppressed, and silver Ion production efficiency is greatly improved.

  On the other hand, when the amount of water flowing through the silver electrolytic cell is lowered by the diversion, the amount of supplied chlorine ions is also reduced and the production of silver chloride is also reduced. That is, since the loss of silver ions is reduced, the production efficiency is greatly improved.

  As described above, according to the present invention, the generation efficiency of silver ions can be greatly improved by suppressing the amount of water flowing through the silver electrolytic cell by the diversion. For this purpose, the diversion ratio with respect to the total flow rate is desirably 80% or less. As a result, it is possible to generate washing water to which silver ions having a sufficient concentration are added even with the limited generated power of the power generation means 500.

  Furthermore, according to the present invention, the pressure loss of the washing water can be greatly reduced by limiting the amount of water flow between the electrodes of the silver electrolytic cell by the diversion. As a result, the power generation amount of the power generation means provided downstream thereof can be increased, and the physical cleaning effect of the water discharge nozzle provided in the toilet can be maintained.

Next, a modified example of the arrangement relationship between the silver electrolytic cell 400 and the power generation means 500 in the toilet flushing water generating apparatus of the present invention will be described.
FIG. 23 is a schematic diagram showing a modified example in which the power generation means 500 is arranged downstream of the silver electrolytic cell 400.
FIG. 24 is a schematic diagram showing a unit including the diversion unit 300, the silver electrolytic cell 400, and the power generation unit 500 in the present embodiment. That is, FIG. 4A is a perspective view showing the appearance, and FIG. 4B is a cross-sectional view showing the internal structure.
Furthermore, FIG. 25 is an enlarged cross-sectional view of the vicinity of the silver electrolytic cell 400.

  That is, in this modification, the diversion means 300 is configured by providing the silver electrolytic cell 400 at one end of the flow path of the washing water. That is, the diversion means 300 includes a first flow path sandwiched between the pair of electrodes 420a and 420b and a second flow path that is not sandwiched between the pair of electrodes. Have. That is, the silver electrolytic cell 400 is arranged so that only a part of the washing water passes between the silver electrodes 420a and 420b. And the water wheel 520 is arrange | positioned so that the whole quantity of washing water may flow in the downstream.

  In the case of the shunt structure described above with reference to FIG. 1, the silver electrolytic cell 400 and the power generation means 500 are arranged in parallel in the branch flow path, so that there is an advantage that the length in the piping direction can be made compact. However, considering that a low flow rate is required for the silver electrolytic cell 400 and a high-speed flow is required for the water turbine 520, the shunt structure shown in FIG. It is somewhat disadvantageous in satisfying these conditions at the same time.

  On the other hand, in the modified examples shown in FIGS. 23 to 25, although the length in the piping direction is slightly longer, the water flows respectively flowing through the silver electrolytic cell 400 and the power generation means 500 are set as described above. The advantage is that it is easy.

  FIG. 26 is a schematic diagram illustrating a second modification of the arrangement relationship between the silver electrolyzer 400 and the power generation means 500. That is, in this modified example, the water flow is branched by the first diversion means 310, the second diversion means 320 is further provided in one of the branch paths, the water flow is branched, and the silver electrolytic cell 400 is arranged on one of them. is doing. If it does in this way, it will become easy to reduce the amount of water supplied to silver electrolysis tank 400 remarkably, and to reduce a flow rate. As a result, the production efficiency of silver ions can be greatly improved. In addition, by combining the two water streams branched by the second branching means 320 and passing the water through the power generation means 500, the flow velocity and the water flow can be adapted to the required characteristics of the power generation means 500, and the amount of power generation can be ensured. It becomes easy.

As can be seen from the above description, a structure in which the silver electrolytic cell 400 is provided only in a part of the water channel of the washing water can be adopted as a diversion unit that can be used in the present invention.
Hereinafter, this shunt structure will be described in more detail.

  FIG. 27 to FIG. 32 are schematic views showing specific examples of the flow dividing structure for the silver electrolytic cell 400. First, in the case of the specific example shown in FIG. 27, the silver electrolytic cell 400 is arranged near the center of the water channel of the washing water. Also in this case, a first flow path sandwiched by the pair of electrodes 420a and 420b and a second flow path not sandwiched by the pair of electrodes are provided in the pipe through which the cleaning water flows. This shunt structure can be said to be a structure with a high degree of freedom in that a silver electrode having a relatively large size comparable to the inner diameter of the pipe can be arranged.

Next, in the case of the specific example shown in FIG. 28, the silver electrolytic cell 400 is disposed near the pipe wall of the cleaning water pipe. In this way, the water flow rate can be reduced by approaching the pipe wall.
FIG. 29 is a schematic view illustrating the flow velocity distribution of water flowing in the pipe. That is, the water flow formed in the pipe has a distribution that is fast in the center and slows as it approaches the pipe wall. Therefore, if the silver electrolytic cell 400 is disposed near the pipe wall of the pipe as in this specific example, it is advantageous in that the flow rate is slow and the amount of water flow can be reduced.

  Next, in the case of the specific example shown in FIG. 30, the silver electrolytic cell 400 is disposed near the pipe wall of the pipe, and further, a throttle hole 430 is provided at the ends of the pair of silver electrodes 420a and 420b. That is, by providing the throttle hole 430 as an outlet for water flowing between the silver electrodes 420a and 420b, it is possible to further suppress the amount of water passing between the electrodes and further increase the generation efficiency of silver ions. Forming a water flow resistance with such a throttle hole is advantageous in that the amount of water flow between the electrodes can be easily reduced without changing the design conditions of the electrodes.

  Next, FIG. 31 is a perspective view of a part of the piping cut out and viewed from the inner wall side. In the case of the specific example shown in the figure, the silver electrodes 420a and 420b are provided so as to protrude in a substantially vertical direction from the pipe wall of the pipe. Also in this structure, as described above with reference to FIG. 29, the water flow rate and flow velocity can be reduced by bringing the silver electrode closer to the tube wall. Further, in the case of this specific example, since only the electrodes are protruded, it is possible to minimize a decrease in conductance with respect to the washing water flowing through the pipe. That is, the pressure loss of the washing water can be reduced, and the power generation efficiency of the generator provided downstream thereof and the washing effect of the water discharge nozzle can be improved.

Next, in the specific example shown in FIG. 32, the pipe has a bent portion, and the silver electrodes 420a and 420b are arranged close to the inner peripheral side of the bent portion. The water flow formed in the bent portion has a distribution in which the flow velocity is fast at the outer periphery and the flow velocity is slow at the inner periphery, as shown by the arrows in FIG. Therefore, by arranging the silver electrodes close to the inner periphery of the bent portion, the flow velocity between the electrodes and the water flow rate can be reduced, and the production efficiency of silver ions can be increased.
In the present invention, by appropriately using the various diversion structures described above, it is possible to reduce the amount of water flow between the electrodes and greatly increase the production efficiency of silver ions.

  As mentioned above, although the specific example which used this invention about the toilet bowl was demonstrated, this invention is not limited to these specific examples.

  For example, the present invention can provide the same effects even when used for the production of toilet flush water. In this case, the present invention can be applied to both a flush valve type toilet and a low tank type toilet.

Furthermore, the present invention can be used for, for example, a hand-washing machine, a kitchen water wash, a bathroom water wash, and the like, in addition to a toilet bowl, to obtain the same sterilizing effect by silver ion water.
FIG. 33 is a schematic diagram showing a specific example in which the present invention is applied to a hand basin for an automatic water faucet. That is, the hand-washing machine 800 has a built-in sensor 160 such as an infrared ray, and when the user approaches the hand, the on-off valve 200 is opened to automatically discharge water. And the outstanding bactericidal action is acquired by eluting silver ion in this water discharge. In the case of this application example, the presence or absence of a user is checked at predetermined time intervals while the sensor 160 is on standby, but this electric power is supplied from the power storage unit 140. This corresponds to the operation of mode 1 described above with reference to FIG.

  On the other hand, when the sensor 160 detects the user, the on-off valve 200 is opened and the silver electrolytic cell 400 is energized to start elution of silver ions. The power supply to the silver electrolytic cell 400 can be performed directly from the power generation means 500. This operation corresponds to mode 2 described above with reference to FIG. At this time, the production efficiency of silver ions can be improved by appropriately using a shunt structure. In this way, by reducing the power consumption for producing silver ions, a part of the generated power can be stored in the power storage unit 140.

  As described above, by appropriately switching between mode 1 and mode 2, and by appropriately using the power from the power generation means 500 and the power from the power storage unit 140, each circuit element can be operated efficiently, and a commercial power source is unnecessary. Automatic faucet / sterilized water discharge type hand-washing machine can be realized.

Furthermore, even in a system that uses a battery instead of a generator, battery consumption can be reduced.
FIG. 34 is a schematic view illustrating a toilet flushing water generator provided with a battery 700 instead of the power generation means. In this generating apparatus, electric power is supplied from the battery 700 to each of the circuit elements of the silver electrolytic cell (first power utilization means) 400 and the second power utilization means 100. The battery in this case may be a primary battery such as a dry battery, or may be a secondary battery such as a nickel-cadmium battery or a fuel cell.

  Also in this system, by appropriately using the shunt structure described above with reference to FIG. 1 or FIGS. 17 to 32, the generation efficiency of silver ions can be greatly improved and the life of the battery 700 can be greatly extended. . As a result, it is possible to reduce the maintenance frequency of battery replacement, and to provide a flush toilet cleaning system that is highly economical and convenient.

The embodiments of the present invention have been described with reference to specific examples. However, the present invention is not limited to these specific examples.
That is, as long as it has the gist of the present invention, those skilled in the art have appropriately changed the design of each element including the silver electrolyzer, the power generation means, the diversion means, and the second power utilization means. Is included.
