Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sterilizing device provided in a toilet flush water supply channel to a flush toilet and a sterilizing water generating device provided in a water channel.

[0002]

2. Description of the Related Art Conventionally, a toilet is routinely cleaned by a manual cleaning device by operating a button of a user, or by automatically detecting when a person stands in front of the toilet and using the toilet. This is performed by an automatic cleaning device which performs an operation of flowing clean water or medium water into the water.

[0003] However, simply flushing water after using the toilet does not prevent gradual adhesion of water stains or slime to the toilet or the generation of odor. Further, in urinals, urine stones adhere to the inside of the pipe to narrow the passage of sewage, or adhere to the surface of the toilet to impair the appearance, become a hotbed of bacteria and emit odors. The urine stones once adhered in this way are difficult to remove by ordinary cleaning, and cannot be removed unless they are strongly rubbed with a brush. For this reason, urolith removal had to be entrusted to a specialized trader, which was a heavy burden.

[0004] Several methods have been disclosed to address this problem by producing and supplying a sterilizing component to the toilet flush water.

For example, the applicant of the present application has noticed that tap water contains chloride ions, and supplies free chlorine-containing water obtained by electrolyzing this water to a toilet to clean the urine such as urine stones. We have proposed a toilet flushing device that can effectively sterilize bacteria causing odor. (PCT / JP95 / 0165

Another example is a toilet flush water supply passage for a flush toilet, an ion generator having a silver plate for mixing silver ions in the toilet flush water supply passage, and a toilet flush water supply passage. There is also known a toilet bowl cleaning water sterilizing and purifying apparatus provided with a power supply device that closes in conjunction with the provided opening / closing valve opening operation and supplies power to a silver electrode plate. (Japanese Utility Model 7-17391)

In each of these inventions, the electric energy is supplied from a commercial power supply such as a home power supply.

[0008]

However, these conventional systems using a commercial power supply have the drawbacks that the equipment cannot be operated at the time of a power failure and that there is a risk of electric shock. In addition to the commercial power source, a battery may be used as a power source for driving a human body detection sensor or the like. In this case, the battery has to be periodically replaced.

SUMMARY OF THE INVENTION The present invention has been made to solve such problems, and has a function of preventing the generation of slime and slime and the generation of odor. The purpose of the present invention is to provide a toilet disinfection device that has functions of preventing the passage of sewage water from being narrowed, aesthetically impaired, and preventing the generation of odor. I do.

[0010]

SUMMARY OF THE INVENTION The present invention relates to a toilet sterilizing apparatus provided in a toilet flush water supply channel to a flush toilet, and a power generating means for generating electrical energy, and a power storage for storing the generated electrical energy. Means and a germicidal component supply means driven by electric energy are provided, and when the toilet flush water is supplied, power is supplied from the power storage means to the germicidal component supply means to supply a germicidal component to the wash water.

Thus, the sterilizing component supply means is driven by the electric energy to supply the sterilizing component into the toilet flush water. As a result, connection to a commercial power supply is not required, and toilet flush water containing a sterilizing component can be supplied even during a power outage. Further, by providing the electricity storage means for storing the electric energy, it is not necessary to directly supply the electric energy generated by the discharge of the cleaning water to the sterilizing component supplying means, and the electric energy supply to the sterilizing component supplying means is not required. You can do it freely. As a result, various combinations of cleaning water spouting and electrolysis for supplying sterilizing components can be achieved.

Further, the present invention is characterized in that when the toilet is not used for a certain period of time, the flush water is automatically discharged, and at the same time, the sterilizing component is eluted from the sterilizing component supply means by supplying electricity from the power storage means.

Slime attached to the surface of the toilet and urine stones formed in drainage pipes are promoted by the activity of bacteria. Therefore, suppressing the growth of bacteria is suitable for the countermeasure against the contamination. The present invention finds that bacteria multiply during nights and holidays when human use of the toilet is stopped, and detects the time zone to discharge water containing sterilizing components. At the same time as sterilization by the sterilizing component, the water in the trap and the drainage pipe is newly replaced, so that the growth of bacteria can be suppressed.

In a preferred aspect of the present invention, the sterilizing component supply means generates silver ions by an electrode reaction, and the material of at least one pair of electrodes is silver.

Thus, silver ions are dissolved from the silver electrode and supplied into the toilet flush water. The silver ion concentration required for sterilization is 2 μg / L or more, and hypochlorite (an iridium-platinum alloy electrode which is an example of the configuration of claim 2 of the present invention) is another sterilizing component. Hypochlorous acid can be generated from chlorine ions in tap water by the electrode reaction.) In this case, a sterilizing effect can be obtained at a lower concentration than that of 500 μg / L or more. Further, these electrode reaction efficiencies (ie, the ratio of the equivalent of the generated sterilizing component to the equivalent of the electrons flowing between the electrodes) are:
It is extremely high in the reaction for generating silver ions from silver. From this, when silver is used as the material of the electrode, a bactericidal effect can be obtained with a very small amount of electrons, that is, a current value. Since the current value is low, power consumption can be reduced under the same electrode shape (electrode area and interelectrode distance) as compared with the case where other sterilizing components are supplied. Further, under the same power consumption condition, the distance between the electrodes can be increased or the electrode area can be reduced. In the former case, since the pressure loss due to the passage of water is reduced, there is no inconvenience that the amount of water flowing in the washing water supply channel per hour (here, this value is referred to as “flow rate”) is reduced. In the latter case, the sterilizing component supply means can be reduced in size and does not hinder use. As described above, silver ions exert a bactericidal effect at a low concentration, so that the power required for generation is only about several tens of milliwatts. Become.

According to a preferred aspect of the present invention, the power generation means in each of the above-mentioned configurations comprises an impeller provided inside the toilet flush water supply channel, and a generator driven by the impeller. The above-mentioned impeller is rotated by the water flow of the washing water supply channel, and the generator is generated by this rotation.

Thus, when water flows through the toilet flush water supply channel, the energy of the water is converted into electric energy by the generator and supplied to the power storage means. The amount of electrical energy generated per hour (such as "watts")
It is proportional to the flow rate (unit is "liter / minute" etc.). In this case, the source of the energy is the kinetic energy of the water flowing through the water supply pipe, and the running cost required for power generation is unnecessary.

In a preferred aspect of the present invention, the electricity storage means stores the electric energy generated by the power generation means one by one every time the toilet flush water is discharged, and stores the stored energy in the flush water of the toilet flush water. And a control unit relating to the above, and use in the sterilizing component supply means.

The kinetic energy of the water flowing in the water supply pipe is
By converting the electric energy into electric energy by the power generation means and storing the electric energy one by one in the power storage means, the energy utilization rate is increased. Since the stored electric energy is diverted to the control unit relating to the flushing of the toilet flush water and the driving of the sterilizing component supply means, a commercial power supply is not required, and the energy can be supplied on its own. In the control section, electric energy is mainly used for a human body detection sensor, opening / closing of a washing water supply valve which is discharged with use of a person, and driving power of a control circuit. In the germicidal component supply means, electric energy is used for energization between the toilet electrodes when the toilet flush water passes between the opposed silver electrodes, and as a result, silver ions are eluted into the wash water.

[0020] More preferably, the impeller serving as the power generation means is provided between the opposed electrodes serving as the sterilization component supply means.

As a result, the power generation and the sterilization component generation can be performed in the same space in the water channel, so that the apparatus is compact.
In addition, since the impeller rotates for power generation, an effect of disturbing the water flow is generated, and an ion concentration gradient near the electrode is eliminated, so that a sterilizing component is easily generated from the electrode.

When the present invention is applied to a urinal,
It has an excellent effect on the antifouling properties of urinals. The reason is described below.

It is considered that the mechanism of urinary stone adhesion to the urinal is as follows. When you urinate in the urinal,
Urine adheres to the urinal surface, and urine stays in the trap section in the urinal. Generally, a large number of bacteria are present in urinals. Urine contains a large amount of urea, but if bacteria are present on the urinal surface or in the trapped water, urea is decomposed into ammonia and carbon dioxide by the action of the enzyme urease possessed by the bacteria. If the amount of ammonia generated at this time is large, it contributes to odor. In addition, when ammonia is generated, the ammonia is dissolved in the liquid attached to the urinal surface or the stagnant water in the trap portion, and the pH of the liquid increases. When the pH rises, the liquid attached to the urinal surface and the calcium ions contained in the trapped water change into carbonates and phosphates and precipitate out, adhere to the urinal as urine stones, and cause stains. Becomes

As described above, in a mode in which the toilet sterilization apparatus according to the present invention is applied to a urinal, the bacteria existing in the urinal are sterilized by flowing the generated sterilizing component to the urinal. The cause of urine stone adhesion is eliminated, the urinal is always kept in a clean state and does not impair the aesthetic appearance, the narrowing of the sewage passage due to the adhesion of urine stones in the piping is prevented, and ammonia, etc. Odor is also prevented from being generated.

Although the above description has been limited to urinals, the present invention is not limited to urinals. Like urinals,
The present invention is applied to a channel such as a local cleaning device for preventing bacterial contamination at a water discharge destination, or a channel such as a bathtub water circulation channel for preventing bacterial contamination. As a configuration according to the aspect of the second invention,
In a sterilizing water generator provided in a water channel, a power generation unit that generates electric energy by a water flow flowing in the water channel, and a power storage unit that stores the generated electric energy.
Providing sterilizing component supply means driven by electric energy,
When water is supplied, power is supplied from the power storage unit to the sterilizing component supply unit, and the sterilizing component is supplied into the water supply. As a result, the sterilizing component supply means is driven by the electric energy to supply the sterilizing component into the water. As a result, there is no need to connect to a commercial power supply, and water containing a sterilizing component can be supplied even during a power failure. Further, by providing the electricity storage means for storing the electric energy, it is not necessary to directly supply the electric energy generated by the water discharge to the sterilizing component supplying means, and the electric energy can be supplied to the sterilizing component supplying means freely. Will be able to As a result, various combinations of cleaning water spouting and electrolysis for supplying sterilizing components can be achieved.

Further, according to the present invention, when the water supply is stopped for a certain time,
The water supply is automatically spouted, and at the same time, the sterilizing component is eluted from the sterilizing component supply unit by the power supply from the power storage unit. Bacterial fouling such as sliminess adhering to the waterway surface is promoted by the activity of bacteria. Therefore, suppressing the growth of bacteria is suitable for the countermeasure against the contamination. The present invention finds that the bacteria grow when it is no longer used by humans, detects the time zone, and discharges water containing a sterilizing component. Simultaneously with the sterilization by the sterilizing component, the water in the waterway is newly replaced, so that the growth of bacteria can be suppressed.

In a preferred aspect of the present invention, the sterilizing component supply means generates silver ions by an electrode reaction, and the material of at least one pair of electrodes is silver. Thus, silver ions are dissolved from the silver electrode and supplied into water. The silver ion concentration required for sterilization is 2
and the other bactericidal component, hypochlorous acid (in the case of using an iridium-platinum alloy electrode which is an example of the constitution of the second aspect of the present invention, chlorine in tap water is caused by an electrode reaction). Hypochlorite can be generated from the ions.), A bactericidal effect can be obtained at a lower concentration than that of 500 μg / L or more. Furthermore, these electrode reaction efficiencies (that is, the ratio of the equivalent of the generated sterilizing component to the equivalent of the electrons flowing between the electrodes) are extremely high in the reaction for generating silver ions from silver. From this, when silver is used as the material of the electrode, a bactericidal effect can be obtained with a very small amount of electrons, that is, a current value. Since the current value is low, power consumption can be reduced under the same electrode shape (electrode area and interelectrode distance) as compared with the case where other sterilizing components are supplied. Further, under the same power consumption condition, the distance between the electrodes can be increased or the electrode area can be reduced. In the former case, since the pressure loss due to the passage of water is reduced, there is no inconvenience that the amount of water flowing through the washing water supply flow path per hour (here, this value is referred to as “flow rate”) is reduced. In the latter case, the sterilizing component supply means can be reduced in size and does not hinder use. As described above, silver ions exert a bactericidal effect at a low concentration, so that the power required for generation is only about several tens of milliwatts. Become.

[0028] In a preferred aspect of the present invention, the power generation means includes a wheel provided inside the water supply channel and a generator driven by the wheel. It is characterized in that it is rotated and the generator generates power by this rotation. Thereby, when the water flows through the water supply channel, the energy of the water is converted into electric energy by the generator and supplied to the power storage means. The electrical energy generated per hour (such as in watts) is proportional to the flow rate (such as in liters per minute). In this case, the source of the energy is the kinetic energy of the water flowing through the water supply pipe, and the running cost required for power generation is unnecessary.

[0029] In a preferred aspect of the present invention, the power storage means stores the electric energy generated by the power generation means one by one every time water is discharged, and stores the stored energy in a control unit related to water discharge. And use in the sterilizing component supply means. The kinetic energy of water flowing in the water supply pipe is converted into electric energy by the power generation means and stored in the power storage means one by one, so that the energy utilization rate increases. Since the stored electric energy is diverted to the control unit relating to the water discharge and the driving of the sterilizing component supply means, a commercial power supply is not required, and the energy can be supplied by itself. In the control section, electric energy is mainly used for a human body detection sensor, opening / closing of a washing water supply valve which is discharged with use of a person, and driving power of a control circuit. In the germicidal component supply means, when water passes between the silver electrodes disposed opposite to each other, electric energy is used for energizing the electrodes, and as a result, silver ions are eluted into the washing water.

[0030] More preferably, the impeller serving as the power generation means is provided between the opposed electrodes serving as the sterilization component supply means. As a result, the power generation and the sterilization component generation can be performed in the same space in the water channel, so that the apparatus becomes compact. In addition, since the impeller rotates for power generation, an effect of disturbing the water flow is generated, and an ion concentration gradient near the electrode is eliminated, so that a sterilizing component is easily generated from the electrode.

Embodiments of the present invention will be described below with reference to the drawings. In this embodiment, an example in which the toilet sterilizing apparatus of the present invention is mainly applied to a urinal is shown, but the same effect can be exerted even when used in a toilet.

FIG. 1 shows a first embodiment of a toilet bowl sterilizing apparatus according to the present invention. An electrolytic cell 7 is provided downstream of the water supply valve 4 including a flush valve of the water supply pipe 3 for toilet flushing. The water supply valve 4 is connected to a known automatic toilet flushing system 2. The toilet flush water pipe 3 is connected to the urinal 1. The water supply pipe 3 between the water supply valve 4 and the urinal 1 is provided with a generator 5 that generates electric energy by itself and a storage electric machine 6 that stores electric energy obtained by power generation. Further, an electrolytic cell 7 for eluting silver ions by electricity from the electric storage device 6 is provided. Inside the electrolytic cell 7, a pair of electrodes 8 a in which metal silver plates serving as sterilizing component supply means are arranged facing each other,
8b are provided.

FIG. 2 is a detailed drawing of the generator 5. There is an impeller 10 that is rotated by toilet flush water flowing through a water supply pipe, and mechanical energy due to the rotation of the impeller 10 is converted into electric energy through interaction with a magnetic field. The generated electric energy is stored in the electric storage device 6 via the electric wiring, and is output one by one to discharge the washing water and elute the sterilizing component.

Next, the operation will be described. The water supply valve 4 is opened by the operation of the automatic toilet flushing system 2, and tap water flows into the generator 5 through the water supply pipe 3 for toilet flushing. This influent causes the impeller 10 to rotate at high speed, and the generator 5 converts the kinetic energy of the water to electrical energy. The generated electric energy is stored in the electric storage device 6. When the sterilizing component is supplied into the washing water, power is supplied to a pair of electrodes 8a and 8b in the electrolytic cell 7 via the control device 9, and silver ions elute from one of the anodes of the electrodes 8a and 8b. Toilet water containing the urine passes through the toilet flush water supply pipe 3 and the urinal 1
Supplied to

The polarities of the electrodes 8a and 8b (ie, the anode and the cathode) are periodically inverted by the control device 9 to prevent scale such as calcium carbonate from adhering to the cathode side. At this time, the electrodes 8a and 8b are consumed with the supply of silver ions, so that the time when the electrode is the anode and the time when the electrode is the cathode are made equal, so that the pair of electrodes 8a and 8b are evenly consumed. The electrodes 8a and 8b can be used up without waste until the end. The electrodes 8a and 8b are preferably made of a pure silver plate in that the electrodes 8a and 8b elute silver ions from themselves, so that the life can be prolonged. However, an alloy containing silver or silver plating may be used.

It is sufficient that at least one of the pair of electrodes 8a and 8b is silver. When an electrode other than silver is used, silver ion can be supplied by switching the polarity of the silver electrode side to the anode by the control device 9. A plurality of pairs of electrodes, at least one of which is silver, may be provided.

FIG. 3 is a flow chart showing control for forcibly discharging flush water and performing electrolysis when the toilet is not used for a predetermined time according to the second embodiment of the present invention. When the use of a person is detected by a human body sensor or the like, the water supply valve 4 is opened, and the flush water flows to the urinal 1 through the water supply pipe 3. When passing through the water supply pipe 2, the impeller 10 in the generator 5 is rotated at high speed, and an electric current is generated by the electromagnetic action. The electric current is taken into the electric storage device 6, and electric energy is accumulated for each discharge of water. With the water discharge, a current flows from the electric storage device 6 to the electrolytic cell 7,
Silver ions are eluted from either side of the silver electrodes 8a and 8b in the electrolytic cell 7. After Ta seconds, the energization of the electrolytic cell 7 ends,
After the next Tb seconds, the water supply valve is closed and the supply of the washing water is stopped. Thereafter, when the use of the person is stopped at night or on holidays, the toilet flushing system 2 automatically opens the water supply valve 4 and forcibly flushes the flush water. At the same time, electrolysis is performed in an electrolytic cell to supply silver ions. The electric power in this case is also supplied from the electric storage device 6. When a person uses the apparatus for a predetermined time, the timer may be built in the toilet flushing system 2 or the control device 9, and the apparatus may count the time until the next use of the toilet.

Further, depending on the manner of use of the toilet, the operation is not necessarily limited to the operation of supplying silver ions at the time of each toilet flush as described above. That is, when it is desired to minimize silver consumption, silver ions may be supplied only at the time of flushing the toilet several times. When it is desired to keep the silver consumption over time constant, an output signal of the controller 9 is connected so as to be input to the automatic toilet flushing system 2, and silver ions are not supplied at the time of flushing the toilet after using the toilet. A mode in which the controller 9 automatically opens and closes the water supply valve 4 by opening and closing the water supply valve 4 via the automatic toilet cleaning system 2 and supplies silver ions only at this time. The above operation connects the output signal of the control device 9 to the toilet automatic cleaning system 2 according to the usage mode of the toilet,
This can be handled by changing the program of the control device 9.

Next, the silver ion concentration and the current required for exhibiting the effects of the present invention will be described. The concentration of silver ions contained in the toilet flush water is preferably at least 2 μg / liter, which is generally said to exert a bactericidal effect. Also, if the silver ion concentration becomes excessive,
Since blackening due to silver oxide or metallic silver deposits may occur on the bowl surface and the trap portion of the urinal 1,
It is preferable to maintain the concentration at not more than μg / liter.

The flow rate of the toilet flush water is generally about 10 liters / minute (= 0.17 liters / second). At this time, a current of only about 0.1 liter flows between the electrodes 8a and 8b in the electrolytic cell 7. When 003A is energized, the electrode reaction efficiency (the proportion of the amount of electricity used to generate silver ions in the amount of electricity flowing between the electrodes 8a and 8b) is assumed to be 100%, and the Faraday constant is 96500. Silver ions flowing out from the anode side of the electrodes 8a and 8b (atomic weight of 107.
9) The concentration is about 20 μg / liter as shown in the following equation. (0.003 × 107.9 / 96500 / 0.17) =
0.197 × 10 ⁻⁴ g / liter = 19.7 μg / liter The electrode reaction efficiency depends on the design of the electrolytic cell 7 (electrode area, distance between electrodes, cross-sectional area of flow path between electrodes, voltage, current, etc.) and toilet flush water. Varies depending on the water quality (electrical conductivity, chloride ion concentration, pH, etc.) of the tap water. Therefore, the silver ion concentration produced is expected to be 10 to 20 μg / liter, which is within the suitable silver ion concentration range.

Next, the required power will be described. Electrode 8
Each of a and 8b is a silver flat plate having a length of 40 mm and a width of 90 mm and the distance between the electrodes is designed to be 10 mm. When 2) was passed at a rate of 10 liters / minute, the voltage required to flow a current of 0.003 A was 9.2 V. The power required at this time is about 0.028 W, which is sufficient power to be generated by the power generated by the generator provided in the water supply pipe. ,

FIGS. 4 and 5 show a third embodiment of the toilet sterilizer according to the present invention. 4 and 5, the power generation means and the sterilizing component supply means are installed using the same space in the water channel. FIG. 5 is a detailed drawing of the electrolytic cell 7 and the generator 5. Inside the electrolytic cell 7, a pair of electrodes 8 each having a flat plate made of metal silver, which is a disinfecting component supply means, arranged facing each other.
a, 8b and an inter-electrode flow path 11 formed between the electrodes
And an impeller 10 provided in the inter-electrode flow path 11, and have a liquid inlet and a liquid outlet communicating with the inter-electrode flow path 11. The impeller 10 and an armature (not shown) connected to the impeller 10 constitute a generator 5 which is a power generating means. Further, the control device 9 controls the generator 5 and the electrodes 8a and 8b.
And connected to. With the above configuration, the contents of the first embodiment described above can be applied to the operation mechanism as it is.

FIG. 6 shows a fourth embodiment of the toilet sterilizer according to the present invention. In the fourth embodiment, the present invention is applied to a toilet. Low tank 1 connected to toilet bowl 12
To 3, a toilet flush water supply pipe 14 is connected and communicates with a low tank water supply pipe 15 in the low tank 13 to constitute a toilet flush water supply path. Water tank 15 in low tank
, A ball tap 16, a power generation unit 17, and an electrolytic cell 19 are provided in this order, and a power storage unit 18 is electrically connected to the power generation unit 17.

Next, the operation will be described. Low tank 1
The water stored in 3 flows into the toilet bowl 12 by rotating the washing cock 20 after use, thereby pulling up the ball chain 21 and operating the on-off valve 22 connected to the tip thereof. When the water level in the low tank 13 drops, the ball tap 16 is activated, and tap water from the toilet flush water supply pipe 14 is supplied by the ball tap 16, the power generation unit 17, and the electrolytic cell 19.
, And electric energy is supplied from the power storage unit 18 to the pair of electrodes 8a and 8b in the electrolytic cell 19 via the control device 9, and silver ions elute from one of the anodes of the electrodes 8a and 8b. Toilet flush water containing silver ions is stored in the low tank 13 and is supplied to the toilet 12 at the next flush.

The electrolytic cell 19, the power generation unit 17 and the power storage unit 1
8 may be provided in the middle of the toilet flush water supply pipe 14 outside the low tank 13.

In each of the embodiments of the present invention described above, a silver electrode is used as a sterilizing component supply means, and silver ions as a sterilizing component are supplied by this electrode reaction. It is not limited to this.

For example, when a chlorine generating electrode is used as an electrode, hypochlorous acid can be generated from chlorine ions in toilet flush water by an electrode reaction. The chlorine generating electrode is an electrode capable of generating a hypochlorous acid generating reaction, for example, an iron-based electrode such as ferrite, a palladium-based electrode, a ruthenium-based electrode, an iridium-based electrode, a platinum-based electrode, and ruthenium-tin. System electrode, palladium-platinum system electrode, iridium-platinum system electrode, ruthenium-platinum system electrode, iridium-platinum-tantalum system electrode and the like.

When these chlorine-generating electrodes are used, the electrode reaction efficiency is lower than that of the silver electrode, and a higher concentration of hypochlorous acid than that of silver is required in order to exhibit a sterilizing effect. Therefore, more current is required than in the case of a silver electrode. At this time, as a method of suppressing an increase in power consumption, it is effective to cause an electrode reaction after mixing a water-soluble salt which is a chlorine compound such as sodium chloride, potassium chloride, or calcium chloride into toilet flush water.
That is, by mixing this salt, the abundance ratio of chlorine ions in the toilet flush water increases, the electrode reaction efficiency improves, and the electrical resistance of the toilet flush water decreases, and the voltage required to flow the same current is reduced. Can be reduced.

Further, the sterilizing component supply means in the present invention is not limited to a device using electrodes, but may be any device that is driven by electric energy and supplies sterilizing components to toilet flush water.

For example, even if the sterilizing agent contained in the tank is configured to be an electric pump, the problem to be solved by the present invention is not lost. As the disinfectant, for example, a silver nitrate solution, a sodium hypochlorite solution, a hydrochloric acid solution, a methylene blue solution, an ethanol solution, a sodium percarbonate solution and the like can be used.

Further, in this specification, the effect of the present invention has been described by taking as an example a power generation means by water flow or a dry battery as the self-contained energy supply means, but other than this, commercial power is not used. If there is, the effect of the present invention is exhibited, for example, power generation by a Peltier element using the difference between room temperature and water temperature, power generation by a piezoelectric element using a pressure difference when water pressure is released, solar cell using lighting in the toilet, etc. Or power generation by means of

As described above, according to the present invention, the urinal is provided with a function of preventing the adhesion of water stains, slime, and the generation of odors. Provide a toilet sterilizer that has both functions to prevent the generation of odor and that can be used even in the event of a power outage, and that the equipment itself can supply the power source that operates the mechanism by generating power, so running costs are not required. be able to.
