Description

  The present invention relates to a generator and a water discharge control device, and in particular, is a generator using hydraulic power, and generates a power by a water flow flowing in a flush toilet or a hand-washer, and is generated by the generator. The present invention relates to a water discharge control device that automatically controls the supply of water discharge by using electric power.

  When flushing water to a flush toilet or a hand-washer, a so-called “automatic washing system” is possible by combining an electromagnetic on-off valve and a sensor. That is, it is possible to detect the user and automatically open the electromagnetic on-off valve to allow the washing water to flow. Furthermore, in such a water discharge control device, when an electrolytic cell is provided and various ions and degradable substances are added to the washing water, useful effects such as sterilization can be obtained. However, electric power is required to operate these electromagnetic on-off valves, sensors, electrolytic cells, and the like. In order to use a so-called commercial AC 100-volt power source as a power source, wiring of an external power line is required. On the other hand, when a power source such as a primary battery or a secondary battery is used, replacement and charging are required according to power consumption.

  On the other hand, if a generator that uses the power of washing water is provided, there is no need for external power line wiring or battery replacement / charging, and a water discharge control device that can accommodate a wide range of installation environments can be realized ( For example, Patent Document 1 and Patent Document 2).

According to these inventions, there is no need to replace a commercial power supply such as a 100-volt power supply for home use or a battery when an automatic cleaning operation or a sterilizing component is added. Can provide a maintenance-free water discharge control device.

  However, in a sanitary facility where a water discharge control device is installed, for example, a flush toilet or a hand-washer, the optimum flow rate varies depending on the device. Moreover, the water supply pressure and the maximum flow rate vary depending on the environment in which these sanitary facilities are installed. Therefore, it is necessary to prepare generators according to the equipment for installing the water discharge control device and the installation conditions thereof.

  For example, depending on the installation conditions of the water discharge control device, the water supply pressure may be high and a flow rate that is larger than the planned water flow amount may flow. In such a case, if the turbine or propeller of the generator rotates faster than the optimum range, an excessive load is applied to the rotating mechanism or the power generating mechanism, and an excessive load may be applied to the power storage means due to overcharging. sell.

  Also in the case of flush toilets, the optimum flow rate differs for each model. For example, the optimal flow rate differs between so-called “spreader-type” urinals and “pile-type” urinals, making it difficult to share generators, and it is necessary to prepare generators suitable for each. is there.

  The present invention has been made on the basis of recognition of such problems, and an object thereof is to provide a generator that can be used in a wide range corresponding to installation conditions and equipment, and a water discharge control device including the generator. There is to do.

At least a part of the flow path from the inflow port to the power receiving body is constituted by a detachable flow path regulating member , and the flow path regulating member uses the water flowing in from the inflow port to the power receiving body. There is provided a generator characterized by forming a first flow path for guiding and a second flow path for guiding water flowing in from the inlet to the outlet without passing through the power receiving member. .

  According to the above configuration, the optimal flow rate regulating member is appropriately selected and mounted, or the flow rate regulating member is appropriately selected between the mounted state and the non-mounted state, so that the power generation amount can be increased even when the optimal flow rate changes.

Further, since there is no need to provide a mechanically operating mechanism such as a variable valve, there is no risk of breakdown or water leakage. Furthermore, since the flow path is not changed by an external operation, there is no malfunction and the device can be easily downsized.

Further , the flow path regulating member includes a first flow path that guides the water that flows in from the inflow port to the power receiving body, and the water that flows in from the inflow port to the outlet without passing through the power receiving body. a second flow path for guiding, form. Thereby, since the flow volume which flows into a power receiving body can be controlled only by changing the cross-sectional area ratio of a 1st flow path and a 2nd flow path, the optimal electric power generation amount can be obtained reliably and easily. In addition, the second flow path acts as a “bypass”, so that a large flow rate can be reliably and easily passed without imposing a burden on the generator or the like and without causing a pressure loss.

Moreover, according to the other aspect of this invention, it moves by receiving the effect | action of the inflow port, the outflow port, the flow path which connects the said inflow port and the said outflow port, and the water flow of the water which flows through the said flow path. A power receiving body, and a power generation unit that converts the motion of the power receiving body into electric power,
At least a part of the flow path from the inflow port to the force receiving member is constituted by a removable flow path regulating member,
As the flow path regulating member, a first flow path regulating member that forms only a flow path that guides the water flowing in from the inlet to the power receiving body, and guides the water flowing in from the inlet to the power receiving body. One of a second flow path regulating member that forms a first flow path and a second flow path that guides water flowing in from the inlet to the outlet without passing through the force receiving member. It is possible to provide a generator characterized in that can be selected.

  By appropriately selecting and installing the first flow path regulating member and the second flow path regulating member, there is no burden on the generator over a wide range from a small flow rate to a large flow rate, and no unnecessary pressure loss occurs. The water can flow reliably and easily.

  In addition, if it is further provided with a discriminating means for discriminating the type of the flow path regulating member, it is possible to automatically change various settings such as various sanitary washing apparatuses that differ depending on the flow rate. In addition, there is no worry about erroneous operations associated with manual changes. Further, there is no need to provide a change switch or the like. Furthermore, if the change is automatically performed, it is not necessary to separately provide a flow rate detecting means.

  Further, if the power receiving body is a water wheel, water flow energy can be reliably and easily converted into mechanical energy with a simple structure.

  On the other hand, according to still another aspect of the present invention, an on-off valve, a sensor, a control unit that controls the operation of the on-off valve in response to a detection signal from the sensor, the on-off valve, the sensor, and the control There is provided a water discharge control device comprising any one of the above-described generators that generates at least part of the power consumed by the unit.

  According to the above configuration, by appropriately selecting and mounting the optimum flow path regulating member, the amount of power generation does not change even if the optimum flow rate changes, and the water discharge that can stably generate power and stably operate A control device can be provided. Further, since there is no need to provide a mechanically operating mechanism such as a variable valve, there is no risk of breakdown or water leakage.

Furthermore, if the change is automatically performed, it is not necessary to separately provide a flow rate detecting means.

  In this specification, “release” of silver ions means that silver ions are liberated from the surface of the silver electrode, and “elution” of silver ions means that the released silver ions are ionized into the washing water. It means to stay.

  ADVANTAGE OF THE INVENTION According to this invention, the water discharge control apparatus provided with the generator which can be used in a wide range corresponding to installation conditions, an apparatus, etc. can be provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
Drawing 1 is a mimetic diagram which illustrates the principal part composition of the discharged water control device concerning an embodiment of the invention. That is, the figure shows the specific example which installed the water discharge control apparatus 10 of this embodiment in the small flush toilet 600. FIG.

  The water discharge control device 10 of the present embodiment includes a control unit 100, a sensor 160, an on-off valve 200, and a generator 500. 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. The on-off valve 200 is automatically opened and closed by the control unit 100. The channel is opened by the opening operation of the on-off valve 200, and the tap water W can flow downstream. A generator 500 is provided downstream of the on-off valve 200. The generator 500 converts part of the water flow energy of the tap water W into electric energy, and supplies it as electric power for the operation of the control unit 100, the sensor 160, and the on-off valve 200. A power storage unit (not shown) may be provided in the control unit 100 so that a part or all of the power generated by the generator 500 can be stored.

  In the water discharge control device 10 of the present embodiment, when the sensor 160 senses a human body, the control unit 100 flows the tap water W by opening the on-off valve 200 for a predetermined time at a predetermined timing. At this time, electric power is generated by the generator 500 and used as a power source of the water discharge control device.

  In the case of such a small flush toilet, the optimum flow rate varies depending on the toilet structure. For example, in the case of a toilet called a “spreader type” or the like, washing water is flowed from a spreader (watering valve) provided at the upper part of the bowl surface, and the optimum flow rate is, for example, about 14 plus or minus 3 liters per minute. On the other hand, in the case of a toilet bowl called “spreading type” or the like, cleaning water is supplied to the bowl surface through a rim (edge) provided around the bowl surface, and the optimum flow rate is, for example, The minute is 21 plus or minus 4 liters.

  Thus, it is necessary to change the flow rate according to the toilet structure. However, if the flow rate flowing through the generator 500 is smaller than the predetermined range, sufficient electric power cannot be obtained. On the other hand, if the flow rate is too large, heat generation due to excess power and wear and damage of mechanical elements such as bearings are accelerated. There's a problem.

  On the other hand, in this embodiment, by providing a replaceable attachment in the generator 500, the flow range that can be adapted can be greatly expanded.

FIG. 2 is a perspective view illustrating the internal structure of the generator 500 of this embodiment.
In other words, the generator 500 includes a housing 510 and a water wheel 520 incorporated therein. The housing 510 is formed with an inlet 512 through which tap water W flows in, an outlet 516 through which tap water W flows out, and a channel 514 that communicates the inlet 512 and the outlet 516. 520 is provided. The side surface of the housing 510 is liquid-tightly sealed. The water turbine 520 rotates in response to the flow energy of the tap water W flowing through the flow path 514, and the kinetic energy due to the rotation is transmitted to a power generation unit having a structure similar to that of a motor and converted into electric energy.

An attachment (flow path regulating member) 550 that regulates the flow path is provided in the middle of the flow path leading to the water wheel 520.
3 to 5 are perspective views showing the assembly of the attachment 550. In FIG. 4, a part of the attachment 550 is cut to show the flow path.

  As shown in these drawings, the attachment 550 is attachable to and detachable from the housing 510, and forms a flow path 552 that reaches the water wheel 520 as a part of the flow path 514 formed in the housing 510. The attachment 550 may be fixed simply by being inserted into a recess provided in the housing 510, or may be fixed to the housing 510 using a fitting mechanism, an adhesive, a screw, or the like (not shown). .

  In the case of this specific example, the flow path 552 formed in the attachment 550 forms only the flow path supplied to the water turbine 520. Then, by replacing the attachment 550, the cross-sectional area of the flow path in the water turbine 520 can be adjusted as appropriate.

  FIG. 6 is a partially enlarged view showing two types of attachments having different channel offset amounts.

  That is, in the case of the attachment 550 shown in FIG. 5A, in the flow channel 554 closest to the water turbine 520, the distance (offset amount) from the tip of the water turbine 520 to the opposed flow channel wall is almost zero. That is, almost all of the water flow flowing through the flow path 554 acts on the water turbine 520.

On the other hand, in the case of the attachment 550 shown in FIG. 6B, the offset amount of the flow path 554 closest to the water turbine 520 is, for example, about 1 millimeter. That is, the distance from the tip of the water turbine 520 to the opposing flow path wall is set to about 1 millimeter. By providing the offset in this way, the action of the water flow on the water turbine 520 can be reduced.
If the attachment 550 is not attached (that is, not attached), the offset amount becomes the largest, and the action of the water flow on the water turbine 520 can be further reduced.

  FIG. 7 is a graph illustrating the relationship between the power generation amount W and the secondary pressure P with respect to the offset amount. Here, the secondary pressure P was expressed as a gauge pressure that the cleaning water has with respect to the atmospheric pressure after passing through the generator.

  That is, when the offset amount is increased, the action of the water flow on the water turbine 520 is reduced, so that the power generation amount W is reduced as shown in FIG. On the other hand, regarding the secondary pressure, if the offset amount is increased, the pressure loss in the flow path 554 is reduced, so the secondary pressure P increases.

  That is, the offset amount may be increased when flowing a flow rate larger than the optimum water amount of the power generation unit, and the offset amount may be reduced when flowing a flow rate close to the optimal water amount of the power generation unit. In this way, not only can the optimal flow rate be supplied to the generator, but there is no unnecessary pressure loss in the power generation section, so the secondary pressure P rises and there are also options for the water discharger that can be installed on the secondary side. spread.

According to the present embodiment, the required amount of discharged water can be adjusted by appropriately replacing the attachment 550 as described above. That is, it is not necessary to replace the entire generator 500, and it is not necessary to manufacture various types of generators 500 according to the flow rate.
In the present invention, the flow path formed by the attachment 550 can be divided by fins or the like to obtain a rectifying effect.
FIGS. 8 and 9 are schematic views illustrating attachments in which the water flow is divided into two flow paths 552 by the fins 553. Thus, when the flow path is appropriately divided by the fins 553 or the like, a rectifying effect is obtained, and a suitable water flow can be formed for the water turbine 520 of the generator and the electrolytic cell described in detail later.
For example, by rectifying the drift generated upstream of the generator, a more uniform flow can be guided to the water turbine, resulting in a decrease in efficiency due to "one-sided" flow to the impeller and durability due to uneven shaft wear. It is possible to suppress problems such as deterioration of sex. Therefore, power generation with excellent pipe connectivity without causing performance degradation even when connecting to upstream parts where flow deviation occurs, for example, immediately after bending of a pipe or immediately after a functional member such as a constant flow valve or valve. Machine can be realized.

Next, the attachment that forms the branch channel will be described.
FIG. 10 is a perspective cross-sectional view showing a generator to which an attachment that forms a branch flow path is attached. Moreover, FIG. 11 thru | or FIG. 13 is a perspective assembly drawing of this example. In addition, in FIG. 12, a part of attachment 550 is cut | disconnected and the flow path is represented.

  Also in this specific example, the attachment 550 may be fixed simply by being inserted into a recess provided in the housing 510, and the housing 510 is used by using a fitting mechanism, an adhesive, a screw or the like (not shown). It may be fixed to.

  In this specific example, the attachment 550 forms a branch channel. That is, when the state in which the attachment 550 is attached to the housing 510 is viewed, the flow path 514 formed in the housing 510 is divided into two flow paths of the first flow path 552 and the second flow path 556 in the attachment 550. Branched.

The first flow path 552 is a flow path that provides a water flow to the water turbine 520, and the second flow path 556 constitutes a so-called “bypass flow path”. That is, in this specific example, the water flow of the tap water W supplied to the generator 500 is diverted, and only a part thereof is applied to the water turbine 520. If it does in this way, it will become possible to flow a large flow of washing water, without giving excessive electric or mechanical load to a power generation part, and controlling loss of pressure. That is, it is possible to flow an amount of washing water that greatly exceeds the optimum flow rate of the power generation unit to a toilet bowl or a washstand.
For example, when the attachment 550 having only the flow path leading to the water turbine is attached as illustrated in FIGS. 2 to 5, 8, 8, and the like, every time it is required for a so-called “spreader-type” small flush toilet. A flow rate of 14 liters per minute plus or minus 3 liters can be flowed. At this time, an optimal water flow can be applied to the water turbine 520 to obtain an appropriate amount of power generation.

  On the other hand, in the generator 500 having the same structure as this, if the attachment 550 that forms the diversion channel is installed as illustrated in FIGS. 10 to 13, it is necessary for a so-called “spray type” small flush toilet. Can wash 21 liters per minute plus or minus 4 liters of washing water. Also at this time, pressure loss can be suppressed by applying an optimal water flow to the water turbine 520 and flowing the remaining water flow downstream through the flow path 556 serving as a bypass.

FIG. 14 is a graph showing an example of a result of the trial examination by the inventor.
That is, FIG. 4A shows the relationship between the flow rate and the amount of power generation, and FIG. 4B shows the relationship between the flow rate and the number of rotations of the power generation unit.

  Here, the curve A represents the case where the attachment 550 having only the flow path leading to the water turbine is attached as illustrated in FIGS. 2 to 5, 8, 9, and the like, and the curve B is illustrated in FIGS. 10 to 13. The case where the attachment 550 which has a shunt flow path as shown in FIG.

  Here, it is assumed that the required power generation amount is 200 milliwatts as represented by the straight line C1. Moreover, the upper limit of the rotation speed of the power generation unit is assumed to be 2000 rotations per minute as represented by the straight line C2. If the rotational speed exceeds the upper limit, bearing wear, vibration, noise, and the like may occur.

  For example, when the attachment that forms only the flow path leading to the water turbine is attached (curve A), the necessary power generation amount is obtained at 11 liters per minute, and when it increases to 17 liters per minute, the power generation amount is 1200 milliwatts or more. (R1). If the amount of power generation is too large, problems such as heat generation may occur due to discarding excess power. At this time, the rotation speed also exceeds the upper limit and increases to about 2800 rotations. In other words, the load may increase mechanically (R3).

  On the other hand, when an attachment having a diversion channel is mounted (curve B), the power generation amount is insufficient at 11 liters per minute (R2), but the required power generation amount is obtained at 17 liters per minute. Further, regarding the rotational speed, the upper limit is not exceeded at 11 liters per minute or 17 liters per minute.

  In other words, when 11 liters of water per minute is required, an attachment (curve A) that forms only the flow path leading to the water wheel may be attached, and when 17 liters of water per minute are required. May be equipped with an attachment (curve B) having a branch channel.

  As described above, according to the present invention, by appropriately selecting and mounting the attachment according to the required amount of water, the mechanical load is suppressed while ensuring the optimum power generation amount, and the pressure loss of the water flow is further reduced. In addition, the required flow rate of water can be allowed to flow.

Next, an embodiment for automatically discriminating the type of attachment in the present invention will be described.
FIG. 15 is a perspective assembly view illustrating a generator capable of automatically discriminating a mounted attachment.
That is, in this specific example, the magnet 580 is embedded in the attachment 550 having the flow path 552 leading to the water turbine as illustrated in FIGS. 2 to 5, 8, and 9. On the other hand, a switch 582 sensitive to magnetic force is embedded in the housing 510. Examples of such a switch include a switch having a switching unit that can move according to a magnetic force, and a hall sensor.

As shown in FIG. 15A, when the attachment 550 in which the magnet 580 is embedded is attached to the housing 510, the switch 582 is activated by a magnetic force.
On the other hand, as shown in FIG. 15B, no magnet is embedded in the attachment having the branch channel 556.
Thus, the switching of the switch 582 can be controlled depending on whether or not a magnet is embedded in the attachment. By using the switching signal from the switch 582, the operation mode of the water discharge control device, the set value of the circuit constant, and the like can be appropriately changed.

FIG. 16 is a perspective assembly diagram showing another specific example of automatic discrimination.
In the case of this specific example, the conductive portion 590 is provided in the attachment 550. The conductive portion 590 can be formed of, for example, metal. Further, a plurality of electrical contacts (not shown) are provided at corresponding locations on the housing 510 corresponding to the conductive portion 590. That is, when the attachment 550 provided with the conductive portion 590 is mounted in the housing 510, the conductive portion 590 appropriately connects a plurality of electrical contacts provided in the housing 510. Therefore, it is possible to discriminate between an attachment provided with the conductive portion 590 and an attachment not provided.

  Further, if three or more electrical contacts are provided on the housing 510 and the pattern of the conductive portion 590 provided on the attachment 550 is appropriately set, it is possible to automatically determine three or more types of attachments by examining the connection state between the electrical contacts.

  As a method for discriminating the attachment 550, in addition to the above-described specific example, for example, various methods such as a method of mechanically switching a switch provided in the housing 510 by attaching the attachment or a method of discriminating by an optical sensor are used. It is possible.

Next, as a specific example of the water discharge control device of the present invention, a water discharge control device provided with an electrolytic cell for adding hypochlorous acid, silver ions, or the like will be described.
FIG. 17 is a conceptual diagram illustrating a water discharge control device provided with an electrolytic cell.
That is, in this specific example, the electrolytic cell 300 is provided between the on-off valve 200 and the generator 500.
FIG. 18 is a perspective view illustrating the internal structure of the electrolytic cell 300.
That is, the electrolytic cell 300 has a pair of electrodes 320a and 320b immersed in the cleaning water, and by applying a voltage between these electrodes, the cleaning water containing a sterilizing component such as hypochlorous acid or silver ions. Can be generated. Examples of the sterilizing component generated in the electrolytic bath 300 include ions of antibacterial metals such as silver (Ag), copper (Cu), and zinc (Zn), free chlorine, ozone, and bonded chlorine.

FIG. 19 is a conceptual diagram showing a mechanism when hypochlorous acid is generated in the electrolytic cell 300. That is, when a voltage is applied to the pair of electrodes 320a and 320b, hydrogen (H ₂ ) and OH ⁻ ions are generated by electrolysis of water at the negative (minus) electrode 420b. On the other hand, in the positive (plus) electrode 420a, electric charges are released from chlorine ions (Cl ⁻ ) contained in tap water, and chlorine gas (Cl ₂ ) is generated. This chlorine gas (Cl ₂ ) is active and combines with water (H ₂ O) in water to produce hypochlorous acid (HClO). This hypochlorous acid has a bactericidal action. Note that as a material of the pair of electrodes 320a and 320b, an alloy of platinum and iridium or the like is preferably used.

Next, a case where silver ions are generated in the electrolytic cell 300 will be described as a second specific example.
FIG. 20 is a conceptual diagram illustrating a mechanism when silver ions are generated in the electrolytic cell 300.
That is, when silver ions are generated, the electrolytic cell 300 is provided with a pair of silver electrodes 320a and 320b. Strictly speaking, the electrode on the positive (plus) electrode side may contain silver. However, when the electrode is used with its polarity reversed, it is desirable that both sides be silver electrodes. When an electric current is passed between these silver electrodes, silver ions are released from the anode (anode) side electrode by an electrolysis reaction. Some of these silver ions combine with negatively charged chlorine ions to produce and consume silver chloride (AgCl), but unreacted silver ions have a bactericidal effect.

  As described above, when washing water to which a sterilizing component such as hypochlorous acid or silver ions described with reference to FIG. 19 and FIG. 20 is added is passed through a small toilet, the antifouling property of the small toilet and its drain pipe Excellent effect in terms of points. The mechanism of adhesion of urine stones to the toilet bowl is considered as follows.

  That is, when urination is performed in the toilet bowl, urine adheres to the surface of the toilet bowl and urine stays in the trap portion in the toilet bowl. 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 a mode in which the water discharge control device of this specific example is adapted to a small flush toilet, the flushing water containing a component having a high bactericidal effect such as hypochlorous acid and silver ions is passed through the toilet bowl. Bacteria present inside can be effectively sterilized. As a result, the cause of urine stone adhesion is eliminated, the toilet is kept clean and the appearance is not impaired, the narrowing of the sewage passage due to the adhesion of urine stone into the pipe is prevented, and Odor generation due to ammonia and the like is also prevented.

  As an example, the inventor conducted an investigation and study on the concentration and sterilization effect of silver ions contained in the washing water to be passed through the flush toilet. As a result, if the addition amount of silver ions is small, the bactericidal effect cannot be sufficiently obtained. On the other hand, if the addition amount of silver ions is too large, consumption of the silver electrode is severe, and silver chloride generated simultaneously with silver ions is not generated. It was learned that discoloration such as “darkening” may occur due to adhesion to the ceramic surface of the toilet. And from these viewpoints, it was found that the amount of silver ions added to the wash water is preferably in the range of 1 to 50 ppb.

  On the other hand, the value of current, voltage, or power to be supplied to the electrolytic cell 300 to generate silver ion water having a predetermined concentration varies depending on the electric conductivity of the supplied tap water.

  FIG. 21 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. In addition, the figure also shows voltage and power characteristic lines corresponding to the 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 flow rate, the applied voltage, and the structure of the electrolytic cell 300. In the specific example shown in FIG. 21, the cleaning flow rate was 14 liters per minute, the opposing portions of the silver electrodes 320a and 320b were approximately 10 mm × 10 mm squares, and the distance between the electrodes was 3 mm. The maximum applied voltage was 30 volts (in the case of low conductivity water), and the maximum current value was 30 milliamperes (in the case of medium water with the lowest cleanliness).

  In order to bring the concentration of the sterilizing component such as silver ions into the optimum range, it is necessary to control the voltage or power applied to the electrolytic cell 300 according to the flow rate of the washing water. For example, the flow rate of washing water differs between a “spreader-type” toilet bowl and a “sprinkle-type” toilet bowl. On the other hand, according to the present invention, as described above with reference to FIGS. 15 and 16, by automatically determining the type of the attachment 550 attached to the generator 500, the flow rate of the corresponding wash water can also be determined. . As a result, the power (voltage) applied to the electrolytic cell 300 can be automatically changed according to the flow rate of the washing water.

FIG. 22 is a cross-sectional view illustrating a specific example of the water discharge control device in which the electrolytic cell 300 is incorporated.
That is, the on-off valve 200, the generator 500, and the electrolytic cell 300 are connected in this order to the secondary side of the water stop valve 50 connected to the primary side water supply pipe. In addition, although the arrangement | positioning relationship of the generator 500 and the electrolytic cell 300 is reverse to what was represented in FIG. 17, this may be any.

  According to the present invention, by appropriately selecting and mounting the attachment 550 of the generator 500, while flowing the required amount of water, the excess or deficiency of the generated power, the increase in pressure loss, the mechanical load of the generator Can be prevented.

As mentioned above, although the specific example using this invention about the flush toilet bowl was demonstrated, this invention is not limited to these specific examples.
For example, the same effect can be obtained even if the present invention is applied to a flush water discharge control device for a toilet.
Moreover, the water discharge control device of the present invention can be used for, for example, a hand-washer, a kitchen flush, and a bathroom flush in addition to a toilet.
FIG. 23 is a schematic diagram showing a specific example in which the water discharge control device of the present invention is applied to a hand basin of an automatic 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. The power supply to the sensor 160 and the on-off valve 200 can be performed directly from the generator 500.

  Even in the case of such a hand-washer, an ordinary water discharge requires an instantaneous flow rate of about 4 liters per minute, and on the other hand, when combined with a water-saving foam water fountain water discharge device or the like, it is about 2 liters per minute. Set to instantaneous flow rate. Therefore, also in this specific example, as described above with reference to FIGS. 1 to 22, by appropriately selecting and mounting the attachment 550 of the generator 500, the water amount required for the hand-washer can be satisfied and stable. Power generation is possible, and an increase in electrical or mechanical load and pressure loss can be suppressed.

  The embodiments of the present invention have been described above with reference to specific examples. However, the present invention is not limited to these specific examples.

  For example, in the case of a water discharge control device provided with a deodorizing fan that rotates with a water flow instead of a generator, by selecting and attaching an attachment appropriately for the required amount of water, the deodorization performance is insufficient or excessive In addition, problems such as noise caused by the rotation of the fan and pressure loss of the supply water can be suppressed.

  In addition, those elements that are appropriately designed and adopted by those skilled in the art for each element including the on-off valve, electrolyzer, generator, attachment, control unit, and sensor constituting the water discharge control device are also applicable as long as they have the gist of the present invention.
