Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a toilet flushing method and a toilet flushing apparatus.

[0002]

BACKGROUND OF THE INVENTION Urinary stones are a major cause of stains on toilet bowls. It is believed that urolith deposits occur in the following process. That is, urea in urine is decomposed by the enzyme urease contained in bacteria to produce ammonia, thereby increasing the pH of the mixed waste water composed of urine and washing water. When the pH increases, the solubility of calcium phosphate generated by the reaction of calcium ions and phosphate ions contained in urine decreases, and calcium phosphate precipitates together with organic components in a toilet or the like. This is urinary stone.

Therefore, conventionally, a method of maintaining the pH of the mixed wastewater at a pH at which calcium phosphate is not easily precipitated, that is, at a low pH has been adopted.

For example, Japanese Patent Publication No. 5-57312 discloses a method in which an acidic substance is added to adjust the pH of urine or mixed waste water of urine and washing water to 5 to 7.5.

[0005]

However, the conventional method of adding an acidic substance cannot sufficiently suppress the generation of ammonia, and cannot be said to be sufficient as a countermeasure against off-odor.

Another problem is that the piping downstream of the toilet may be corroded.

Further, maintenance for replenishing the acidic substance is required, and the replenishment work may be dangerous.

The present invention has been made in view of the above-mentioned problems, and has been made in view of the above problem. The main purpose is to provide a cleaning method.

Furthermore, compared to the conventional method of adding an acidic substance, there is no need for maintenance, and a toilet flushing apparatus which is safe for the user is provided.

When urine is applied to the toilet, the urine adheres to the surface of the toilet and the urine stays in the water retained in the toilet. Generally, bacteria such as bacilli exist in the toilet. Urine contains a large amount of urea, but when bacteria are present on the surface of the toilet or in the water retained in the toilet, 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 an unpleasant odor. In addition, when ammonia is generated, the ammonia is dissolved in a liquid attached to the surface of the toilet or in water retained in the toilet, and the pH of the liquid increases. When the pH rises, the liquid attached to the surface of the toilet and the calcium ions contained in the stagnant water in the toilet change form into carbonates and phosphates and precipitate out, and adhere to the toilet as urine and cause coloring stains. Becomes

In the conventional method of adding an acidic substance, pH
By preventing the increase in urine stones. Therefore, the production of ammonia itself could not be sufficiently suppressed, and was not satisfactory as a countermeasure for off-flavor.

On the other hand, in the present invention, the production of ammonia itself is suppressed by effectively removing the enzyme urease out of the toilet or inhibiting the action of the enzyme urease, so that the increase in pH due to the dissolution of ammonia is suppressed. In addition to preventing the adhesion of urinary stones, it can also prevent one cause of unpleasant odor.

A step of killing bacteria containing urease;
When a step of removing urease outside the toilet is provided, the enzyme urease can be effectively removed outside the toilet for the following reasons.

The enzyme urease is present in human urine, but is most frequently distributed in bacteria such as bacilli. Therefore, the amount of enzyme urease increases if bacteria existing on the surface of the toilet or in the stagnant water in the toilet increase, and if the bacteria adhere firmly to the toilet, the enzyme urease is firmly fixed to the toilet.

Therefore, if bacteria containing urease are sterilized and the number of viable bacteria is reduced, an increase in the amount of enzyme urease can be suppressed, and the viscous organic matter generated by the vital activity of the bacteria and toilet cells together with viable bacteria The amount of enzyme urease firmly fixed on the surface can also be reduced.

As described above, when the number of viable bacteria, the amount of viscous organic substances or the amount of enzyme urease is reduced, the enzyme urease can be removed from the toilet by washing with water, so that the production of ammonia is suppressed and the pH due to the dissolution of ammonia is reduced. Is prevented from being attached, urine stones are prevented from adhering, and a cause of an unpleasant odor is also prevented.

The step of inhibiting the enzymatic action of urease, instead of killing the bacteria having urease, also suppresses the production of ammonia, suppresses the increase in pH due to the dissolution of ammonia, and prevents adhesion of urine stone. In addition, the cause of the unpleasant odor is prevented.

The step of inhibiting the enzymatic action of urease includes, for example, heavy metal salts, halogen, boric acid, quinone,
A step of bringing a substance that inhibits the enzymatic action of urease, such as hydrogen peroxide, into contact with the toilet can be suitably used.

A step of inhibiting the enzymatic action of urease;
When a step of removing urease outside the toilet is provided, inhibition of urease enzyme action and removal of urease can be achieved.
In two independent ways, the production of ammonia will be suppressed. Therefore, the generation of ammonia is further suppressed, the increase in pH due to the dissolution of ammonia is suppressed, the adhesion of urine stones is prevented, and the cause of the unpleasant odor is also prevented.

A step of killing bacteria containing urease;
And the step of inhibiting the enzymatic action of urease, the increase in the urease by viable bacteria, the effect of fixing is suppressed, and the inhibition of the enzymatic action by urease possessed by the remaining bacteria, further ammonia production Is suppressed. As a result, an increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stone is prevented, and a cause of an unpleasant odor is also prevented.

[0191] The method for killing bacteria containing urease and inhibiting the enzymatic action of urease is provided.
The increase and fixation effect of urease by viable bacteria are suppressed, and the production of ammonia is further suppressed in combination with the effect of inhibiting the enzymatic action of urease of the remaining bacteria. As a result, the pH due to the dissolution of ammonia
Of urine stones is prevented from rising,
The cause of the off-flavor is also prevented.

A step of killing bacteria containing urease;
By having a step of inhibiting the enzyme action of urease and a step of removing urease out of the toilet, the increase and fixation effect of urease by viable bacteria are suppressed. In an independent manner, the production of ammonia will be suppressed. Therefore, the generation of ammonia is further suppressed, the increase in pH due to the dissolution of ammonia is suppressed, the adhesion of urine stones is prevented, and the cause of the unpleasant odor is also prevented.

By providing a step of killing bacteria containing urease and inhibiting the enzymatic action of urease, and a step of removing urease out of the toilet, an increase in urease due to live bacteria, suppression of the fixation effect, and an urease enzyme Since the production of ammonia accompanying the action can be suppressed at the same time, and the urease whose adhesion has been suppressed is removed, the production of ammonia is further suppressed, and the increase in pH due to the dissolution of ammonia is suppressed. In addition to preventing the adhesion of urinary stones, it also prevents the cause of off-flavor.

The step of killing bacteria containing urease comprises:
When the step of contacting a substance or ions having a bactericidal property with a toilet bowl is safer than methods such as ultraviolet irradiation, there is no change in the ambient temperature compared to methods such as heating, It is preferable because there is no discomfort.

Here, in the step of bringing a substance or ions having a sterilizing property into contact with a toilet, a method of flowing a liquid containing a substance or ions having a sterilizing property into a toilet, a substance having a sterilizing property or ions or a substance containing them For example, a method in which is fixed to the surface of a toilet (for example, in glaze) can be suitably used.

The step of killing bacteria containing urease comprises:
If it is a step of contacting a liquid containing a sterilizing substance or ion with the toilet, without replacing the existing toilet, for example, means for generating a liquid containing a sterilizing substance or ion in the upstream piping It is preferable to provide a urine stone and a bad smell only by providing a storage tank or the like.

It is preferable that the step of removing urease outside the toilet is a step of removing bacteria along with the washing water outside the toilet because the existing washing facility can realize the step.

When the step of removing urease outside the toilet is a step of removing bacteria together with a liquid containing a bactericidal substance or ion, the liquid containing a bactericidal substance or ion is removed from the toilet. Flow from the upstream piping,
Only by discharging from the downstream pipe, the step of sterilizing bacteria containing urease and the step of removing urease out of the toilet can be realized at the same time, which is simple and preferable.

The liquid containing a bactericidal substance or ion contains a substance that inhibits the enzymatic action of urease, or contains a bactericidal substance that inhibits the enzymatic action of urease. By doing so, the increase and fixation effect of urease by viable bacteria are suppressed, and furthermore, the production of ammonia is suppressed by two independent methods of inhibiting the action of urease enzyme and removing urease. . Therefore, the generation of ammonia is further suppressed, the increase in pH due to the dissolution of ammonia is suppressed, the adhesion of urine stones is prevented, and the cause of the unpleasant odor is also prevented. Furthermore, since it is brought into contact with liquid, without replacing the existing toilet bowl, for example, only providing a tank or the like for storing a liquid containing a sterilizing substance or ion in the upstream piping, the adhesion of urine stones and an unpleasant odor are improved. Is preferred.

If the pH of the liquid containing a substance or ion having a bactericidal property is 5.5 or less, the following two effects are produced in addition to the above-mentioned effects, and adhesion of urine stone and generation of ammonia are less likely to occur.

(1) The solubility of calcium phosphate is extremely low when the pH is 8 or more, but by setting the pH to 5.5 or less, the solubility of calcium phosphate is increased and adhesion of urolith hardly occurs.

(2) It is said that the optimum activity pH of the enzyme urease is about 7. By adjusting the pH to 5.5 or less, the activity of the enzyme urease is greatly reduced, and the generation of ammonia hardly occurs.

However, if the acidity is strong, the piping may be corroded. Therefore, the pH is preferably 3 or more.

If the liquid containing a bactericidal substance or ion is a liquid containing free chlorine, free chlorine has a high bactericidal activity in a small amount and also has an effect of inhibiting the enzymatic action of urease. In addition, the generation of ammonia is further suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented. In addition, since it is brought into contact with a liquid, without replacing the existing toilet, for example, by merely providing a tank for storing a liquid containing a sterilizing substance or ion in the upstream pipe, adhesion of urine stones and off-flavors are improved. Is preferred.

Further, since the water is generated only by electrolysis of water containing chlorine such as tap water, the water is generated only by disposing the electrolyzer upstream of the pipe, and it is not necessary to provide a tank or the like. Further, compared with the conventional cleaning method in which an acidic substance is added, there is less need for maintenance such as replacement of the liquid in the tank, which is safer for the user.

When the liquid containing a bactericidal substance or ion is a liquid containing bound chlorine, the bound chlorine has a bactericidal activity and also has an effect of inhibiting the enzymatic action of urease. The generation of ammonia is suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and the adhesion of urine stone is prevented, and the cause of the unpleasant odor is also prevented. In addition, since it is brought into contact with a liquid, without replacing the existing toilet, for example, by merely providing a tank for storing a liquid containing a sterilizing substance or ion in the upstream pipe, adhesion of urine stones and off-flavors are improved. Is preferred.

Further, since water is generated only by electrolysis of water containing chlorine and organic nitrogen such as middle water and well water, the water is generated only by disposing the electrolyzer upstream of the piping, and it is not always necessary to provide a tank or the like. It does not take up space and reduces the need for maintenance, such as replacing liquid in the tank. And since middle water can be used as raw water, it is easy to cope with high-rise buildings, factories, and the like in which water is recycled. In addition, bonded chlorine is less likely to decompose spontaneously than free chlorine, and thus has an advantage of good persistence. Furthermore, it has a strong bactericidal power that can kill bacteria with an action time (residence time) of about 5 minutes. This will be described in detail in Example 11 described later.

If the liquid containing a substance or ions having a bactericidal property is ozone-containing water, the ozone-containing water has a bactericidal activity and has an action of oxidizing ammonia. This suppresses the increase in pH due to the dissolution of ammonia, thereby preventing the adhesion of urine stones and preventing a cause of an unusual odor. In addition, since it is brought into contact with a liquid, without replacing the existing toilet, for example, by merely providing a tank for storing a liquid containing a sterilizing substance or ion in the upstream pipe, adhesion of urine stones and off-flavors are improved. Is preferred.

Furthermore, since ozone generated by silent discharge can be obtained only by dissolving in water or electrolysis of water, it is not necessary to provide a tank or the like if an ozone generation unit that causes such a reaction is arranged upstream of the pipe. Without taking up space,
The need for maintenance, such as replacing the liquid in the tank, is also reduced.

When the liquid containing a substance or ions having bactericidal properties is a liquid containing antibacterial metal ions,
Since the antibacterial metal ion has a bactericidal activity, the production of ammonia by urease is suppressed, the increase in pH due to the dissolution of ammonia is suppressed, the adhesion of urine stones is prevented, and the cause of the unpleasant odor is also prevented. In addition, since it is brought into contact with a liquid, without replacing the existing toilet, for example, by merely providing a tank for storing a liquid containing a sterilizing substance or ion in the upstream pipe, adhesion of urine stones and off-flavors are improved. Is preferred.

[0211] When the concentration of free chlorine is 0.1 mg / L or more, preferably 0.5 mg / L or more, accumulated water in the toilet and the surface of the toilet are sufficiently sterilized. Therefore, the increase in urease based on the action of viable bacteria and the fixation effect are effectively suppressed, and the pH due to the dissolution of ammonia is reduced.
Of urine stones is prevented from rising,
The cause of the off-flavor is also prevented.

Since free chlorine is produced only by electrolysis of water containing chlorine such as tap water by making free chlorine obtained by electrolyzing chlorine ion-containing water, the electrolysis apparatus is connected to a pipe. It is generated only by arranging it upstream, and it is not necessary to provide a tank etc., so it does not take up space, and compared with the conventional cleaning method that adds an acidic substance, the necessity of maintenance such as exchange of liquid in the tank Less and more secure for the user.

When the liquid containing a substance or ions having a bactericidal property is an acidic liquid containing free chlorine, the adhesion of urine stones and off-flavors are further improved by the following actions.

(1) Free chlorine has a high bactericidal activity in a small amount and also has an effect of inhibiting the enzymatic action of urease.

(2) Since the pH does not easily rise to 8 or more, urolith made of calcium phosphate or the like hardly adheres.

(3) Free chlorine is present as hypochlorous acid (HClO) in acidity. In such a form, hypochlorite ion (ClO ⁻ ), which is an alkaline form, is present.
It has about 10 times stronger sterilizing power compared to. Therefore, the production of ammonia is suppressed, the increase in pH due to the dissolution of ammonia is suppressed, the adhesion of urine stones is prevented, and the cause of the unpleasant odor is also prevented.

The ozone concentration in the ozone-containing water is 0.01
When the amount is not less than mg / liter, preferably not less than 0.05 mg / liter, accumulated water in the toilet and the surface of the toilet are sufficiently sterilized. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented.

If the ozone-containing water is ozone-containing water obtained by dissolving ozone generated by silent discharge in water or generating ozone in water by electrolysis of water, a silent discharge type ozone generator or electric ozone generator may be used. Ozone-containing water is generated only by disposing the decomposition device upstream of the pipe, so it is not necessary to provide a tank or the like, so it takes less space, and compared to the conventional cleaning method in which an acidic substance is added. There is less need for maintenance such as the exchange of liquids, and it is safer for the user.

When the antibacterial metal ion is silver ion and the silver ion concentration is 1 μg / liter or more, preferably 10 μg / liter or more, a liquid containing silver ion is mixed with the water retained in the toilet, and the water is mixed for a predetermined time. By maintaining, the water retained in the toilet bowl is effectively sterilized. Therefore,
The increase and fixing effect of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and the adhesion of urine stones is prevented, and at the same time, one of the causes of unpleasant odor is also prevented.

Here, the antibacterial metal ion has a lower bactericidal ability by instant contact than free chlorine and ozone, but has a long antibacterial life and has an excellent antibacterial property by prolonging the action time. Therefore, when used in such a manner as to maintain the water in the toilet bowl for a predetermined time, viable bacteria are reduced in a small amount, and adhesion of urine stones is prevented.

If the liquid containing the antibacterial metal ion is a liquid containing the antibacterial metal ion released by the antibacterial metal ion carrier, the maintenance can be performed only by replacing the antibacterial metal ion carrier. , More secure and preferred.

When the antibacterial metal ion carrier is arranged in the trap portion of the toilet bowl in which the retained water is stored, the retained water is sterilized by releasing the antibacterial metal ions into the retained water, and the action of live bacteria is performed. The effect of increasing the amount of urease and the effect of fixation are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and the adhesion of urine stones is prevented, and at the same time, the cause of the unpleasant odor is also prevented.

Here, the antibacterial metal ion has a lower sterilizing ability by instantaneous contact than free chlorine and ozone, but has a long antibacterial life and has an excellent antibacterial property by prolonging the action time. If used in such a manner that the stagnant water in the toilet is maintained for a predetermined time, viable bacteria are reduced in a small amount,
This is preferable because adhesion of urine stones and the like can be prevented.

By flowing a liquid containing a sterilizing substance or ion into the toilet at predetermined time intervals, live bacteria are intermittently killed and removed. It is possible to effectively prevent the growth and fixation of the viable bacteria attached. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented.

A liquid containing a sterilizing substance or ion is allowed to flow through the toilet only at night, for example, in an office building, a department store, a station yard, an exhibition hall, a tourist facility, a vehicle operating only in the daytime, and the like. In toilets that are used only in the daytime and are hardly used at night, such as toilets installed in toilets, bacteria grow in the water remaining in the toilet when nighttime toilets are not used, and urease increases and adheres to the surface of the toilet This situation is prevented, so that the adhesion of urine stones is prevented, and at the same time, one cause of the unpleasant odor is also prevented. In the daytime, the stagnant water in the toilet is replaced by the usual lavatory flush every time the lavatory is used or at a predetermined time interval, so that bacteria do not propagate in the stagnant water and urease does not increase.

As described above, when a liquid containing a sterilizing substance or ion is allowed to flow only at night, first, flush water is poured into the toilet to replace the water remaining in the toilet, and then the sterilizing substance or ion is discharged. It is good to make the liquid containing containing into a toilet bowl. In toilet flushing, most bacteria are usually flushed out of the toilet, as 99% of the retained water is designed to be replaced by fresh water. Accordingly, the remaining bacteria are sufficiently sterilized by subsequently flowing a liquid containing a substance or ions having a sterilizing property through the toilet.

When a liquid containing a sterilizing substance or ion is allowed to flow only at night, a high-concentration or large-volume flow is applied only at the first time of the night, and the second or subsequent time during the night. Alternatively, a liquid containing a substance or ions having a low concentration or a small amount of bactericidal property may be flowed.
Since the number of bacteria gradually increases in the daytime, the number of bacteria in the stagnant water is the highest at night. Therefore, it is necessary only at the beginning to perform sufficient sterilization with a liquid containing a substance or ions having a high concentration or a large amount of sterilization. However, since the growth rate of bacteria is low at night, after sufficient sterilization is performed in this manner, sufficient sterilization can be performed simply by flowing a liquid containing a substance or ion having a low concentration or a small amount of sterilization. be able to.

By flowing a liquid containing a sterilizing substance or ion into a toilet only at night at predetermined time intervals, for example, in an office building, department store, station yard, exhibition hall, tourist facility, daytime, etc. In toilets that are used only in the daytime and are rarely used at night, such as toilets installed in toilets of vehicles that operate only, bacteria grow in the stagnant water in the toilet when nighttime toilets are not used, and urease increases. The situation of sticking to the surface of the toilet bowl is prevented, so that the adhesion of urine stone is prevented, and the cause of the unpleasant odor is also prevented. Further, by intermittently flowing the liquid, it is possible to save a liquid having a sterilizing substance or ion.

[0229] In this case as well, first, flush water is flushed into the toilet to replace the water remaining in the toilet, and then a liquid containing a sterilizing substance or ion is preferably flushed into the toilet. Alternatively, a high concentration may be allowed to flow only at the time of the first flow at night, and a lower concentration of germicidal substance or ion may be flowed at the second time or later during the night.

Bacteria multiply in the stagnant water in the toilet when the toilet is not used by allowing the liquid containing a sterilizing substance or ion to flow into the toilet when the toilet is not used within a certain time after the toilet is used. However, it is possible to prevent a situation where urease increases and sticks to the surface of the toilet, thereby preventing urine stones from adhering and also preventing an unpleasant odor. If the toilet is used relatively frequently, the accumulated water in the toilet is replaced by normal toilet flushing each time the toilet is used (or at a predetermined time interval), so that bacteria may grow in the accumulated water. And urease does not increase.

When the toilet is not used within a certain period of time after using the toilet, a liquid containing a sterilizing substance or ion is allowed to flow into the toilet at predetermined time intervals. Bacteria grow in the resident water,
Urease is prevented from increasing and sticking to the surface of the toilet bowl, thereby preventing urine stones from adhering.
The cause of the off-flavor is also prevented. Further, by intermittently flowing the liquid, it is possible to save a liquid having a sterilizing substance or ion.

By allowing a liquid containing a substance or ions having a sterilizing property to flow into the toilet every time the toilet is washed after using the toilet, urine does not stay on the toilet or on the surface of the toilet, so that urine does not stay on the toilet. In addition, since the growth of bacteria is prevented and the amount of urease is not increased, the production of ammonia is effectively suppressed, thereby preventing the adhesion of urine stone and the cause of the unpleasant odor.

[0233] A liquid containing a substance or ion having a sterilizing property is allowed to flow into the toilet just before or immediately after the end of flushing after use of the toilet, so that the surface of the toilet wet by the flushing of the toilet after use of the toilet is disinfected. Substances or ions having a property diffuse widely. As a result, the toilet bowl surface is effectively sterilized, the increase in urease is prevented, the production of ammonia is effectively suppressed, and furthermore, the adhesion of urine stones is prevented, and at the same time, the cause of the unpleasant odor is also prevented.

If the liquid containing a sterilizing substance or ions is allowed to flow into the toilet after the water remaining in the toilet trap is replaced with the toilet flushing water immediately before the sterilization, the bacteria in the water remaining can be reduced and the sterilizing property can be reduced. Since a liquid having a substance or ions having the compound is allowed to act, the toilet surface is effectively sterilized with a small amount of a substance having a bactericidal property, an increase in urease is prevented, and the production of ammonia is effectively suppressed. The urine stones are prevented from adhering, and one of the causes of the unusual odor is also prevented.

When a liquid containing antibacterial metal ions is stored as stagnant water in the toilet only at night, the antibacterial metal ions have a lower sterilizing ability by instantaneous contact than free chlorine or ozone. Since the antibacterial life is long and the antibacterial property is excellent by prolonging the action time, the viable bacteria are reduced in a small amount and the increase of urease is prevented if used in such a state that the water stays in the toilet for a predetermined time. As a result, the production of ammonia is effectively suppressed, thereby preventing the adhesion of urine stones and also preventing a cause of an unpleasant odor.

If the liquid containing antibacterial metal ions is stored as stagnant water in the toilet when the toilet is not used within a certain period of time after using the toilet, the antibacterial metal ions are compared with free chlorine and ozone. Therefore, although the sterilizing ability by instant contact is low, the antibacterial life is long, and the antibacterial property is excellent by extending the action time. The number of viable bacteria is reduced, the increase in urease is prevented, the production of ammonia is effectively suppressed, and the adhesion of urine stone is prevented, and at the same time, the cause of the unpleasant odor is also prevented.

The concentration of free chlorine in the water containing free chlorine flowing into the toilet is 0.2 μg / liter or more, preferably 0.02 mg / liter.
When the amount is not less than 1 / liter, the water remaining in the toilet and the surface of the toilet are sufficiently sterilized. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented.

When the number of bacteria in the water in the toilet bowl increases, urine stones adhere to the toilet bowl by the above-mentioned process. However, since the urine stone is porous, water easily stays in the pores, and bacteria grow. Cheap. Thus, a vicious cycle occurs in which an increase in the number of bacteria creates an environment for further increasing the number of bacteria. However, by constantly maintaining the number of bacteria in the toilet stagnation water at less than 1 × 10 ⁴ CFU / milliliter, it is possible to break such a vicious cycle and maintain a state in which urine stone does not adhere to the toilet. Therefore, when a liquid containing a bactericidal substance or ions is passed through a toilet, it is desirable to always maintain the number of bacteria in the toilet water at a level of less than 1 × 10 ⁴ CFU / ml. For this purpose, a liquid containing a bactericidal substance or ions may be constantly flowed into the toilet, or may be flowed after replacement of the water remaining in the toilet by ordinary toilet cleaning. When a liquid containing a bactericidal substance or ions is constantly passed through the toilet, the above-mentioned target of the number of bacteria can be achieved by setting the free chlorine concentration to 0.2 μg / liter or more. In addition, when a liquid containing a bactericidal substance or ions is allowed to flow into the toilet after replacing the toilet water by ordinary toilet flushing, the free chlorine concentration is set to 0.02 mg / liter or more, so that the target for the number of bacteria can be reduced. Can be achieved. It should be noted that, as for the cleaning of the toilet surface, sufficient cleaning can be achieved if the above conditions are satisfied. This is because the place where bacteria are most likely to multiply in the toilet is toilet bowl water, and if a liquid containing bacterial substances or ions is flowed into the toilet so that the bacterial count there is always below the target value, it will be higher than the toilet bowl water. This is because the target can naturally be achieved even on the surface of the toilet bowl with a low bacterial count.

[0239] A liquid containing a germicidal substance or ions is allowed to flow when the toilet is not used for a predetermined time after flushing the toilet after using the toilet, and the germicidal substance or ions containing the germicidal substance or ions are firstly flown into the toilet at that time. Even if the liquid is free chlorine-containing water having a free chlorine concentration of 0.1 mg / liter or more, the target of the number of bacteria can be achieved.

In addition, a liquid containing a germicidal substance or ions is allowed to flow into the toilet only at night, and a liquid containing a germicidal substance or ions that first flows into the toilet at night has a free chlorine concentration of 0.1 mg / liter. Even with the above-mentioned water containing free chlorine, the target of the number of bacteria can be achieved.

In the conventional washing that is usually performed after the toilet is used, 99% or more of the water remaining in the trap portion of the toilet is replaced. However, since sterilization is not performed in the conventional washing, bacteria existing on the surface of the toilet or in the stagnant water gradually grow. For example, in the case of an office building, free water containing free chlorine is flowed at 3:00 am the day before to reduce the number of bacteria to 0, and then only normal washing is continued until 10:00 pm. The number increases with time, and at most the number of bacteria in the resident water increases to about 1 × 10 ³ CFU / ml. As described above, the number of bacteria increases while the toilet is used relatively frequently, which means that the number of bacteria is highest during the first washing when the toilet is no longer used. Therefore, at this time, sufficient sterilization is carried out by flowing a water containing free chlorine having a concentration as high as 0.1 mg / liter or more. However, the growth rate of the bacteria while the toilet is not in use is low, so it is sufficient to flush the free chlorine-containing water at a lower concentration thereafter. Thereby, power consumption for electrolysis can be reduced, and the life of the electrode can be extended.

[0242]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, a specific configuration of the present invention will be described.

Bacteria containing urease are bacteria having urease in the body, and generally include all bacteria. Among them, bacilli are particularly remarkably inhabited in toilets.

In the step of sterilizing bacteria, for example, when the surface of a toilet is targeted, a method of heating and sterilizing the surface of the toilet, a method of providing an ultraviolet irradiation means on the surface of the toilet and sterilizing with ultraviolet light, a method of chemically sterilizing the toilet, And a method of sterilizing by modifying the material of the toilet surface.

In the case of the sana portion and the trap portion, which are in contact with the staying water of the toilet, a method of sterilizing by heating, a method of providing an ultraviolet irradiation means on the surface of the trap portion or the like, and sterilizing with the ultraviolet light, A method of chemically disinfecting, a method of disinfecting by modifying the material of the surface of the trap portion or the like can be used.

Here, in the method of heating and sterilizing the toilet surface, a heater is basically provided on the toilet surface to heat it. It is preferable to arrange a transparent electrode on the glaze surface so as not to impair the design of the toilet bowl provided with the glaze.
For example, a tin oxide electrode can be suitably used for the transparent electrode.

In this case, after the transparent electrode is applied on the glaze layer, it is obtained by a method of heating and fixing tin oxide at a temperature at which the glaze softens, a method of attaching a transparent electrode sheet on the glaze layer, or the like. Can be.

The same method can be used for sterilizing the sana portion and the trap portion.

A method of sterilizing the toilet bowl surface with ultraviolet light is as follows.
Basically, an ultraviolet irradiation means is provided on the toilet surface to irradiate ultraviolet light. A germicidal lamp (wavelength: about 250 nm) is preferable for the ultraviolet irradiation means because it can sterilize even relatively weak illuminance. As the ultraviolet irradiation means, a panel-shaped ultraviolet irradiation means is preferable because it does not take up space, does not impair the design of the appearance, and can be easily fixed by sticking, bonding or the like. Also, from the viewpoint of safety, it is preferable to provide a control means for preventing the sterilization operation when the toilet is used. Further, in the case of a urinal, if an ultraviolet irradiation means is provided on the rim portion or the stagnation portion, the ultraviolet light does not directly enter the user's eyes even in the case of a malfunction, so that it is safer.

The same method can be used for sterilizing the sana portion and the trap portion.

In the method of disinfecting the toilet surface with ultraviolet light, it is preferable that the photocatalyst be fixed on the toilet surface, because even a weak ultraviolet light such as sunlight, fluorescent light, indoor lighting, etc. can be sterilized. . To fix the photocatalyst on the toilet bowl surface, apply the photocatalyst on the glaze layer, fix it at the temperature at which the glaze softens, mix it with a photo-corrosion-resistant material such as an inorganic binder and fix it, and form a photocatalyst sheet And sticking. In any method, the photocatalyst fixed layer is preferably transparent so as not to impair the design property of the glaze. For that purpose, the size of the particles and pores or the thickness of the fixed layer in the photocatalytic fixed layer is
It is preferable that the wavelength is not more than の of the wavelength of visible light, that is, not more than 0.2 μm. In addition, if a photocatalyst is added not only with an optical semiconductor but also with a metal capable of capturing electrons when electrons and holes are generated on the optical semiconductor by photons, holes disappear due to recombination with electrons. Can be reduced, sterilization is mainly due to active oxygen generated by the reaction of holes and hydroxide ions, etc., will have a stronger sterilizing power,
preferable. Metals that can capture electrons include platinum, gold, silver,
Copper and the like are available, but silver or copper is preferable because it has a bactericidal effect by the oligomer effect itself and exhibits antibacterial properties even in the dark.

In the case of a urinal, if an ultraviolet irradiation means is arranged on the rim portion or the stagnation portion and a photocatalyst fixing layer is provided so as to oppose the ultraviolet irradiation means, an ultraviolet illuminance stronger than the indoor lighting can be applied to the toilet surface. Because it can work
The germicidal power is further improved, and even if a malfunction occurs, the ultraviolet rays do not enter the user's eyes directly, so that it is safer.

The same method can be used for sterilizing the sana portion and the trap portion if an ultraviolet irradiation means is provided.

The method of chemically sterilizing a toilet bowl surface is basically a method of bringing a substance having a sterilizing property into contact with the toilet bowl surface. Examples of the mode include a method of providing a sterilizing solution supply means upstream of the toilet pipe and appropriately flowing the solution to the toilet, a method of spraying a sterilizing application liquid on the surface of the toilet, and a method of spraying a sterilizing gas on the surface of the toilet.

Here, the method of providing a sterilizing solution supply means upstream of the toilet pipe and appropriately flowing the solution to the toilet means that a sterilizing solution such as a tank storing a sterilizing solution or an electrolyzer is provided upstream of the toilet. This is a method in which a means for generating the cells is provided and the number of viable cells is prevented from increasing by appropriately flushing the toilet.

The germicidal substances include free chlorine, antibacterial metals or their ions, ozone, ozone-containing water, bound chlorine, organochlorine disinfectants, organophosphate disinfectants, beloxocarbonate ions or Salts, alcohol-based disinfectants and the like can be mentioned.

Of these, free chlorine, bound chlorine, ozone,
Ozone-containing water is preferable because it has a short life of at most several weeks in water as compared with an organic chlorine-based disinfectant, an organic phosphoric acid-based disinfectant, or the like.

Furthermore, free chlorine, bound chlorine, and ozone-containing water can be generated only by electrolysis of water supplied from a pipe such as tap water, so that there is little need for maintenance.

The antibacterial metal or its ion has a small atomic or ionic size, and thus its antibacterial life is exhausted when it is surrounded by an organic substance or a relatively large anion. However, there is an advantage that the action time is longer than free chlorine, bound chlorine, ozone, ozone-containing water and the like. Therefore,
In the case of staying water, it is preferable to dispose a substance containing an antibacterial metal or its ion in the trap portion and to have excellent bactericidal properties without supplying a new bactericidal component for a considerably long period of time.

The method of sterilization by modifying the material on the surface of the toilet is basically, for example, a method of applying or mixing a substance having a sterilizing property on the surface of the toilet.

The substance having excellent bactericidal property which is excellent to be applied or mixed on the toilet surface is preferably a substance having heat resistance from the viewpoint of ease of toilet production, and a substance containing an antibacterial metal or its ion is preferred. .

Here, examples of the substance containing an antibacterial metal or its ion include the antibacterial metal or its ion itself, a compound containing the antibacterial metal or its ion, or a substance carrying the antibacterial metal or its ion.

Antibacterial metals include silver, copper, zinc and the like, and glaze, glass, soluble glass, layered silicate, layered aluminosilicate, apatite, calcium phosphate can be used as a carrier for the antibacterial metal or its ion. , Aluminum phosphate, zeolite, zinc oxide, iron oxide, titanium oxide and the like can be used.

Among these, since they have heat resistance even at the firing temperature of sanitary ware, glaze, glass, apatite,
Calcium phosphate, aluminum phosphate, zinc oxide, iron oxide and titanium oxide are particularly preferred.

[0265] The step of removing urease out of the toilet is a step of removing urease or bacteria having urease existing on the surface of the toilet or in the retained water outside the toilet. As a specific method, there are a method of flowing out of the toilet together with water, washing water, a sterilizing liquid, and the like, and a method of decomposing urease by a chemical method, a thermal method, or the like. Since urease is a substance that is quite stable as an enzyme, it is preferable that the urease be flown out of the toilet together with water, washing water, a bactericidal liquid, and the like.

The step of inhibiting the enzymatic action of urease refers to the step of inhibiting or slowing down the action of urease as an enzyme. More specifically, a substance that inhibits the enzymatic action of urease is brought into contact with urease or a urease-bearing bacterium that is attached to the toilet bowl surface or is present in the retained water.

As a substance that inhibits the enzymatic action of urease, a substance containing a heavy metal, halogen, boric acid, quinone, hydrogen peroxide and the like can be used.

Substances that inhibit the enzymatic action of urease
In order to contact urease or bacteria that carry urease that is attached to the toilet surface or present in the stagnant water, a liquid containing heavy metal salts, halogen, boric acid, quinone, hydrogen peroxide, or the like is passed through the toilet, A heavy metal salt, halide, borate or the like is fixed on the surface of the toilet trap or the like, and is brought into contact with urease existing along with attached bacteria.

Further, in the toilet trap section, a solid substance on which heavy metal salts, halides, borates and the like are immobilized may be arranged so as to be brought into contact with urease existing with bacteria in the stagnant water. .

The step of killing bacteria and inhibiting the enzyme action of urease refers to the step of simultaneously killing and inhibiting or slowing down the action of urease as an enzyme. More specifically, a substance that simultaneously sterilizes and inhibits or slows down the action of urease as an enzyme is brought into contact with bacteria that carry urease that is attached to the toilet bowl surface or present in the stagnant water.

As a substance which simultaneously performs sterilization and inhibition or blunting of urease as an enzyme, substances containing silver, copper, zinc or ions thereof, free chlorine, bound chlorine and the like can be used.

For contacting a substance which simultaneously sterilizes and inhibits or slows down the activity of urease as an enzyme with urease or urease-containing bacteria present on the toilet bowl surface or in the retained water, silver, copper, A substance containing zinc or its ion, free chlorine, a liquid containing bound chlorine, etc. is flowed into the toilet, or silver,
A substance containing copper, zinc or its ions is immobilized and brought into contact with attached bacteria.

In the toilet trap section, silver,
A solid material on which a substance containing copper, zinc or its ions is fixed may be provided so as to be brought into contact with urease existing with bacteria in the resident water.

Here, free chlorine means hypochlorous acid and hypochlorite ion. The term "bound chlorine" refers to monochloramine, dichloramine, trichloramine, etc. Among them, monochloramine and dichloramine are known to have bactericidal activity.

When a liquid containing free chlorine is used, it is preferable to supply water containing chlorine, such as tap water, medium water, well water, and industrial water, by electrolysis. This is because a liquid containing free chlorine is not suitable for storage since the amount of free chlorine gradually decreases when left untreated.

[0276] The electrolyzer uses a method in which an anode and a cathode are separated by a diaphragm, separated into alkaline water and acidic water, taken out, and only the acidic water is supplied to the toilet. There is a way to flush the toilet.

The method of flowing all the electrolyzed liquid in a non-diaphragm type into a toilet is preferable when a large amount of washing water is required at once, such as a toilet unit in which a plurality of toilets are simultaneously provided.

Conversely, a method of separating the anode and the cathode with a diaphragm and separating and taking out the alkaline water and the acidic water is a method of disposing the alkaline water and the acidic water upstream of a water supply pipe in a general household or the like, and supplying the alkaline water for drinking and freeing it. It is suitable for combination with other uses such as flowing acidic water containing chlorine through a toilet.

[0279] Free chlorine exists in the form of hypochlorite (HClO), which is more bactericidal, in acidic solutions.

A method for electrolyzing chlorine ion-containing water is as follows:
In order to improve the efficiency of generating free chlorine by making the chlorine generation reaction dominant over the oxygen generation reaction, an electrolysis apparatus using a chlorine generation electrode is used at least for the anode electrode.

Here, the chlorine generation electrode is an electrode capable of inducing a chlorine generation reaction, and its basic structure is either a conductive base material carrying a chlorine generation catalyst or a conductive material comprising a chlorine generation catalyst. Made of conductive material.

Depending on the type of the chlorine generating catalyst, for example, iron-based electrodes such as ferrite, palladium-based electrodes, ruthenium-based electrodes, iridium-based electrodes, platinum-based electrodes, ruthenium-based electrodes
There are a tin-based electrode, a palladium-platinum-based electrode, an iridium-platinum-based electrode, a ruthenium-platinum-based electrode, an iridium-platinum-tantalum-based electrode, and the like.

[0283] The structure in which the chlorine-generating catalyst is carried on the conductive base material is advantageous in terms of manufacturing cost because the base material for the structure can be made of inexpensive materials such as titanium and stainless steel.

In particular, when using tap water having a chlorine ion content of only about 3 to 40 ppm in water containing chlorine ions, improving the generation efficiency of free chlorine is not enough to sterilize bacteria containing urease. Is very important in. From that viewpoint, an iridium-based electrode, an iridium-platinum-based electrode, an iridium-platinum-tantalum-based electrode, and the like are preferable.

In order to extend the life of the electrode, when a conductive base material carrying a catalyst for generating chlorine is used, it is preferable that platinum is included, because the base material is fixed to the base material better and hardly detached.

The voltage applied to the electrodes in the electrolysis tank may be a DC voltage or an AC voltage. When the voltage applied to the electrodes is an AC voltage, it is desirable to use chlorine generating electrodes for both electrodes.

In other cases, the cathode electrode may be basically made of any conductive material. For example, using inexpensive materials such as iron and stainless steel is advantageous in terms of manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A toilet bowl cleaning apparatus according to the present invention will be described below. In addition, although the following description mainly deals with urinals, the same configuration and cleaning method can be used to prevent yellowing of toilets.

FIG. 1 shows an embodiment of a toilet flushing apparatus according to the present invention, which comprises at least a pair of electrodes, a channel formed between the electrodes, a liquid inlet and a liquid outlet communicating with the channel. Has a continuous electrolysis tank 1 via a first branch pipe 2
The toilet flushing water supply pipe 3 is connected to a position upstream of a water supply valve 4 such as a flush valve. An on-off valve 5 composed of a solenoid valve or the like is arranged on the way of the first branch pipe 2. The continuous electrolysis tank 1 is connected via a second branch pipe 6 to a position downstream of the water supply valve 4 of the water supply pipe 3 for toilet flushing. The toilet flush water supply pipe 3 to which the second branch pipe 6 is connected,
It is connected to urinal A1. A control device 7 containing a timer is connected to the electrolysis tank 1 and the on-off valve 5. The water supply valve 4 is connected to a known automatic toilet flushing system B1.

[0290] In this toilet bowl washing device, the opening / closing valve 5 is appropriately opened by the control device 7 based on the instruction of the timer.
Tap water flows from the toilet flush water supply pipe 3 upstream of the water supply valve 4 through the first branch pipe 2 into the flow path formed between the electrodes of the continuous electrolysis tank 1. Simultaneously with or slightly after opening of the on-off valve 5, a voltage is applied between the electrodes by the control device 7, and tap water flowing through the flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed. To produce free chlorine-containing water. The generated free chlorine-containing water flows through the second branch pipe 6 into the toilet flushing water supply pipe 3 located downstream of the water supply valve 4, and flows into the urinal A1. Thereby, the toilet A1 is appropriately sterilized, and the urease contained in the bacteria is flown out of the urinal A1 together with the bacteria, so that the precipitation of urine stones is prevented, and the urine A1 is prevented from being stained. .

Independently of the operation of the toilet flushing apparatus, tap water is flushed into the urinal A1 each time the toilet flushing system A1 is operated or manually, and the surface of the urinal A1 is flushed. The remaining water in the toilet trap is replaced.

[0292] In this toilet bowl cleaning device, free chlorine-containing water, which is a toilet bowl cleaning solution, is generated by electrolysis of tap water. There is little need for maintenance and it is safe for users.

[0293] In this toilet bowl cleaning device, the control device 7 opens the on-off valve 5 at predetermined time intervals based on the instruction of the timer, and simultaneously or slightly delays the opening and closing of the on-off valve 5 by the control device 7. When a voltage is applied between the electrodes and the tap water flowing through the flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed to generate free chlorine-containing water, live bacteria are intermittently Since the bacteria are killed and removed, the growth and fixation of viable bacteria adhering to the toilet bowl from outside air or the like can be effectively prevented. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented. In addition, by intermittent electrolysis, the life of the electrodes in the electrolyzer can be improved, and the need for maintenance can be further reduced. Furthermore, the amount of water and electricity is saved as compared with the case of always flowing, so that resource and energy are saved.

[0294] The time interval when the water containing free chlorine is supplied to the toilet at predetermined time intervals is preferably a time interval shorter than the time during which a predetermined concentration of free chlorine is consumed. When free chlorine disappears, foreign bacteria are not killed, which leads to bacterial growth and, consequently, an increase in urease. The relationship between the free chlorine-containing water addition time interval and the free chlorine concentration is shown by the solid line in FIG. The time interval at which the predetermined concentration of free chlorine-containing water flows into the toilet is to the left of the solid line in this figure, that is, at a short time interval.

[0295] In the toilet flushing device, the control device 7 opens the on-off valve 5 only at night based on the instruction of the timer, and at the same time as or slightly after opening the on-off valve 5,
When voltage is applied between the electrodes by the control device 7 and the tap water flowing through the flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed to generate free chlorine-containing water, for example, Non-nighttime toilets, such as toilets installed in office buildings, department stores, station premises, exhibition halls, tourist facilities, and vehicles that operate only during the daytime, such as toilets used only during the daytime and hardly used at night Occasionally, bacteria are propagated in the stagnant water in the toilet bowl, preventing the situation where urease increases and sticks to the toilet bowl surface, thereby preventing urine stones from adhering and also preventing one cause of unpleasant odor.
In the daytime, tap water is flushed into the urinal A1 by the operation of the automatic toilet flushing system B1 or manually, every time the toilet is used or at a predetermined time interval, independently of the operation of the toilet flushing device, or manually. Since the surface of the toilet A1 is washed with water and the accumulated water in the toilet trap is replaced, bacteria do not grow in the accumulated water and urease does not increase.

In this case, based on the instruction from the timer, the control device 7 opens the on-off valve 5 only at night at predetermined time intervals, and simultaneously or slightly delays the opening of the on-off valve 5. A voltage is applied between the electrodes,
If the tap water flowing through the channel formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed to generate free chlorine-containing water, the life of the electrodes in the electrolyzer is further improved, and the maintenance time is reduced. The need can be further reduced. Further, since the amount of water and electricity is reduced as compared with the case of always flowing, it is preferable to save resources and energy.

In the toilet bowl cleaning apparatus, the following may be performed. The control device 7 is connected to the automatic toilet flushing system B1 so that the signal from the control device 7 allows the automatic toilet flushing system B1 to perform normal toilet flushing. Then, when the free chlorine-containing water is supplied only at night as described above, first, the control device 7 sends a cleaning signal to the automatic toilet flushing system B1, and flushes the flushing water to the toilet. This displaces the stagnant water in the toilet bowl (which replaces about 99% of the stagnant water with fresh water) and removes most of the bacteria out of the toilet bowl. Thereafter, the control device 7 opens the on-off valve 5 as described above, and applies a voltage between the electrodes at the same time or with a slight delay. Then, tap water flowing through a flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed, and free chlorine-containing water is generated and flown to the toilet A1. Thereby, the remaining bacteria are sufficiently sterilized.

In this toilet cleaning apparatus, the control device 7 is further connected to the automatic toilet cleaning system B1, and an operation signal of the automatic toilet cleaning system B1 is input to the control device 7 and controlled by the operation signal of the automatic toilet cleaning system B1. The timer of the device 7 is started, and when the toilet is not used within a certain time after the use of the toilet by the control device 7, that is, a predetermined time after the urinal A1 is used and the operation signal of the automatic toilet cleaning system B1 is output. When the operation signal of the automatic toilet bowl cleaning system B1 is not output within the time period, the on-off valve 5 is opened based on the instruction of the timer, and at the same time as or slightly after the on-off valve 5 is opened, the controller 7 inter-electrodes. Is applied, and the tap water flowing through the flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed to generate free chlorine-containing water. It preferred because the same effect as described above can be obtained even in the. In this method, the effect of resource saving and energy saving is the greatest.

The opening / closing valve 5 is opened and the opening / closing valve 5 is opened each time the toilet 7 is used by the device 7, ie, every time the urinal A1 is used and the operation signal of the automatic toilet cleaning system B1 is output. Simultaneously or slightly delayed by the instruction of the timer, a voltage is applied between the electrodes by the control device 7, and the tap water flowing through the flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed, When free chlorine-containing water is generated, sterilization and inhibition of the enzymatic action of urease are performed together with the supply of urea, so that the production of ammonia is effectively suppressed,
As a result, the adhesion of urine stones is prevented, and the cause of the unpleasant odor is also prevented.

[0300] Also, compared with the case of always flowing, the life of the electrodes in the electrolyzer is improved, the necessity of maintenance can be further reduced, and the amount of water and electricity is saved, so that resources can be saved. Energy saving is preferable.

In the toilet bowl cleaning apparatus, the control device 7 is also connected to the automatic toilet bowl cleaning system B1, and an operation signal of the automatic toilet bowl cleaning system B1 is input to the control device 7, and the control device is operated by the operation signal of the automatic toilet bowl cleaning system B1. 7 is started, and immediately before or immediately after the end of the toilet flush after the toilet is used by the control device 7, that is, the urinal A
1 is used and the operation signal of the automatic toilet cleaning system B1 is output, and after a slight delay, the on-off valve 5 is opened based on the instruction of the timer. Is applied, and the tap water flowing in the flow path formed between the electrodes of the continuous electrolysis tank 1 is electrolyzed to generate free chlorine-containing water. Immediately before or immediately after the termination, the water containing free chlorine is caused to flow into the toilet, so that the water containing free chlorine diffuses widely on the surface of the toilet that has been wet by the automatic flushing system B1. As a result, the surface of the toilet is effectively sterilized, and an increase in urease is prevented, so that the production of ammonia is effectively suppressed, thereby preventing the adhesion of urine stones and also preventing a cause of an unpleasant odor. Will be.

[0302] In the toilet bowl washing apparatus, a flow control valve may be provided in the middle of the first branch pipe 2 instead of the on-off valve 5. The control device 7 opens the flow control valve at a predetermined time,
This is set to a predetermined opening. If the opening of the flow control valve is increased, the amount of tap water flowing into the continuous electrolysis tank 1 per unit time is also increased, the concentration of free chlorine generated by electrolysis is reduced, and if the opening is reduced, The flow rate of tap water also decreases, and the concentration of free chlorine increases. When the flow control valve is used instead of the on-off valve 5, the concentration of free chlorine can be adjusted by a flow control method.

Independently of the operation of the toilet flushing apparatus, the tap water is flushed into the urinal A11 every time the toilet flushing system is used or manually by operating the toilet flushing system B11, and the surface of the urinal A11 is flushed. Then, the water retained in the toilet trap A12 is replaced.

[0306] In the toilet flushing apparatus, free chlorine-containing water, which is a toilet flushing liquid, is generated by electrolysis of tap water. There is little need for maintenance and it is safe for users.

[0307] In the toilet bowl washing device, the control device 17 controls the on-off valve 1 at predetermined time intervals based on the instruction of the timer.
Simultaneously or slightly after opening of the valve 5 and opening of the on-off valve 15, a voltage is applied between the electrodes by the control device 17 and flows through the flow path formed between the electrodes of the continuous electrolytic cell 11. If tap water is electrolyzed and free chlorine-containing water is generated, live bacteria will be intermittently killed and removed, so that live bacteria flowing from outside air into the stagnant water of toilet trap A12 will be removed. Proliferation and sticking to the toilet trap A12 can be effectively prevented. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented.

During the daytime, tap water is flushed into the urinal A11 by the operation of the automatic toilet flushing system B11 or manually, independently of the operation of the toilet flushing device, every time the toilet is used or at a predetermined time interval. Since the surface of the toilet A11 is washed with water and the retained water in the toilet trap A12 is replaced, bacteria do not propagate in the retained water and urease does not increase.

In this case, based on the instruction of the timer, the control device 17 opens the on-off valve 15 only at night at predetermined time intervals, and simultaneously or slightly delays the opening of the on-off valve 15.

The control device 17 is connected to the automatic toilet flushing system B11 so that the signal from the control device 17 allows the automatic toilet flushing system B11 to perform normal toilet flushing. Then, when the free chlorine-containing water is supplied only at night as described above, first, the control device 17 sends a cleaning signal to the automatic toilet flushing system B11, and flushes the toilet. This displaces the stagnant water in the toilet bowl (which replaces about 99% of the stagnant water with fresh water) and removes most of the bacteria out of the toilet bowl. Thereafter, the control device 17 opens the on-off valve 15 as described above, and applies a voltage between the electrodes at the same time or with a slight delay. Then, the continuous electrolysis tank 11

However, even if free chlorine-containing water is generated, the same effect as described above can be obtained, which is preferable. In this method, the effect of resource saving and energy saving is the greatest.

[0312] In this toilet cleaning apparatus, the control device 17 is also connected to the automatic toilet cleaning system B11, and an operation signal of the automatic toilet cleaning system B11 is input to the control device 17 to be controlled by the operation signal of the automatic toilet cleaning system B11.

FIG. 3 shows another embodiment of the toilet flushing apparatus according to the present invention, in which at least one pair of electrodes, a channel formed between the electrodes, a liquid inlet and a liquid outlet communicating with the channel. And the continuous electrolysis tank 21 having the
3 is disposed on the way downstream of the water supply valve 24 composed of a flush valve and the like. The control device 27 is connected to the continuous electrolysis tank 21. The water supply valve 24 is connected to a known automatic toilet flushing system B21. The toilet flush water pipe 23 is connected to the urinal A21.

[0316] In the toilet flushing apparatus, the water supply valve 24 is opened by the operation of the automatic toilet flushing system B21, and the tap water passes through the toilet flushing water pipe 23 to supply tap water to the continuous electrolysis tank 2.
It flows into a flow path formed between one electrode. The control signal to the water supply valve 24 is also sent from the automatic toilet flushing system B21 to the control device 27. A voltage is applied between the electrodes by the control device 27 that has received the signal, and the tap water flowing through the flow path formed between the electrodes of the continuous electrolytic bath 21 is electrolyzed. The free chlorine-containing water generated by the electrolysis is passed to the urinal A21 through the toilet flush water supply pipe 23.

As a result, the water containing free chlorine flows into the toilet A21 each time it is used.
With the supply of urea, sterilization and enzymatic inhibition of urease are carried out, the production of ammonia is effectively suppressed, and furthermore, the adhesion of urine stones is prevented, and at the same time, the cause of the unpleasant odor is also prevented.

This toilet flushing device also requires less maintenance and is safer for the user than the conventional flushing device in which chemicals are mixed into the flush water.

[0319] In the toilet flushing apparatus, a timer is provided in the control device 27, and after the control device 27 receives a control signal to the water supply valve 24 from the automatic flushing system B21, the water supply valve 24 is opened. Immediately before the end of the time, a voltage may be applied between the electrodes, and the tap water flowing through the flow path formed between the electrodes of the continuous electrolytic bath 21 may be electrolyzed.

Spread widely. As a result, the toilet surface is effectively disinfected, and the increase in urease is prevented, so that the production of ammonia is effectively suppressed, thereby preventing the adhesion of urine stones and also preventing a cause of an unusual odor. become.

Each of the toilet flushing apparatuses shown in the embodiments of FIGS. 1 to 3 has a continuous electrolytic bath. The continuous electrolysis tank may have any structure, provided that tap water containing chlorine ions can be electrolyzed efficiently in a flowing water state, not in a stored state. Also, from the viewpoint of energy saving,
It is desirable to use a non-diaphragm type electrolysis tank in which no diaphragm is interposed between the electrodes. In a non-diaphragm type electrolysis tank, the power required for electrolysis can be reduced by narrowing the interval between the electrodes. Further, since the electrode interval can be narrowed, the size and size of the electrolysis tank can be easily reduced.

As the electrolysis tank having the above characteristics, for example, the electrolysis method disclosed in PCT / JP95 / 01036, that is, between at least a pair of electrode plates separated from each other by 0.2 mm or more. A method in which a flow path of tap water is provided, and a direct current of 300 to 1100 A / m ² is passed through the electrode plate, more preferably, the distance between the electrodes is 0.4 mm or more, and the direct current voltage is 400 to 600 A / m ^2.
The electrolysis tank using the method of setting to (2) can be suitably used.

FIG. 4 shows another embodiment of the toilet flushing apparatus according to the present invention.
2, the toilet flushing water supply pipe 33 is connected to a position upstream of a water supply valve 34 such as a flush valve. A flow control valve 35 is provided in the middle of the first branch pipe 32. The water storage type electrolysis tank 31 is connected via a second branch pipe 36 to a position downstream of the water supply valve 34 of the toilet flush water supply pipe 33. An on-off valve 39 is provided on the way of the second branch pipe 36. The toilet flush water supply pipe 33 to which the second branch pipe 36 is connected is connected to the urinal A31.
The control device 37 is connected to the electrode of the water storage type electrolysis tank 31, the float sensor 38, and the on-off valve 39.

In this toilet flushing apparatus, a small flow of tap water is constantly supplied from the flushing water supply pipe 33 upstream of the water supply valve 34 through the first branch pipe 32 and the flow control valve 35. It flows into the tank 31. The water level in the water storage type electrolysis tank 31 is detected by a float sensor 38. When the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, a voltage is applied between the electrodes by the control device 37 which has received the detection signal from the float sensor 38, and the voltage in the water storage type electrolysis tank 31 is increased. Is electrolyzed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 which has received the detection signal from the float sensor 38 opens the on-off valve 39 to generate the electrolysis. The free chlorine-containing water flows through the on-off valve 39 and the second branch pipe 36, flows into the toilet flushing water supply pipe 33 downstream of the water supply valve 34, and flows into the urinal A31.

Here, the time when the electrode is submerged and the time when the water level in the water storage type electrolysis tank reaches a predetermined value may be detected by directly measuring the water level with the float sensor as described above, or the on-off valve may be used. The detection may be performed by measuring the lapse of time from the time of opening.

Independently of the operation of the toilet flushing apparatus, the tap water is flushed into the urinal A31 every time the toilet flushing system A31 is operated or manually, and the surface of the urinal A31 is flushed. The remaining water in the toilet trap is replaced.

[0327] This toilet flushing device, like the toilet flushing device of Figs. 1 to 3, requires less maintenance and is safe for the user as compared with a conventional flushing device in which chemicals are mixed into flush water. .

In the above apparatus, by appropriately setting the flow rate of the flow control valve 35, the water containing free chlorine can flow into the urinal A31 at predetermined time intervals. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented. In addition, by intermittent electrolysis, the life of the electrodes in the electrolyzer can be improved, and the need for maintenance can be further reduced. Furthermore, the amount of water and electricity is saved as compared with the case of always flowing, so that resource and energy are saved.

In the toilet flushing apparatus of FIG. 4, the following may be performed. Connect the control device 37 and the flow control valve 35,
A timer is provided in the control device 37. After the flow rate control valve 35 is appropriately opened by the control device 37 so as to be adjusted to a predetermined flow rate, the water flows through the first branch pipe 32 and the flow rate control valve 35 from the toilet flush water supply pipe 33 upstream of the water supply valve 34. hand,
Tap water with a small flow rate always flows into the water storage type electrolysis tank 31. When the on-off valve 39 is opened by the control device 37, the free chlorine-containing water generated by the electrolysis passes through the on-off valve 39 and the second branch pipe 36, and is discharged from the water supply valve 34 of the toilet flush water supply pipe 33. Enter the downstream position and urinal A
Flowed to 31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 3
9 is closed and the flow control valve 35 is closed simultaneously or slightly later.

In this case, a small flow rate of tap water is always supplied from the toilet flush water supply pipe 33 upstream of the water supply valve 34 to the storage type electrolysis tank 31 through the first branch pipe 32 and the flow control valve 35. After the inflow, the on-off valve 39 is opened. Free chlorine-containing water generated by the electrolysis flows through the on-off valve 39 and the second branch pipe 36 to a position downstream of the water supply valve 34 of the toilet flush water supply pipe 33, and flows to the urinal A31. The operation during is the same as above. That is, the water level in the water storage type electrolysis tank 31 is detected by the float sensor 38, and when the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, the control receiving the detection signal from the float sensor 38 A voltage is applied between the electrodes by the device 37, and the stored water in the water storage type electrolysis tank 31 is electrolyzed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 that has received the detection signal from the float sensor 38 opens the on-off valve 39.

[0331] By doing so, the flow control valve 35 can be opened only when necessary by the instruction of the timer, and the water containing free chlorine can flow into the urinal A31. In addition, the need for maintenance can be further reduced. Further, since the amount of water and electricity is reduced as compared with the case of always flowing, it is preferable to save resources and energy.

In the toilet flushing apparatus of FIG. 4, the following may be performed. Connect the control device 37 and the flow control valve 35,
A timer is provided in the control device 37, and the flow rate control valve 35 is opened only at night so that the flow rate is adjusted to a predetermined value. From the toilet flush water supply pipe 33 upstream of the water supply valve 34, the tap water with a small flow rate always flows into the water storage type electrolysis tank 31 through the first branch pipe 32 and the flow control valve 35. The water level in the water storage type electrolysis tank 31 is detected by the float sensor 38, and when the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, the control device 37 receives the detection signal from the float sensor 38. As a result, a voltage is applied between the electrodes,
The water stored in the water storage type electrolysis tank 31 is electrolyzed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 which has received the detection signal from the float sensor 38 opens the on-off valve 39 to generate the electrolysis. The free chlorine-containing water flows through the on-off valve 39 and the second branch pipe 36 to a position downstream of the water supply valve 34 of the toilet flush water supply pipe 33, and the urinal A
Flowed to 31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 3
9 is closed, and the flow control valve 35 is closed simultaneously or slightly later.

In this way, the free chlorine-containing water flows into the toilet A31 only at night, so that, for example,
When a toilet bowl is used only during the day and rarely used at night, such as a toilet installed in an office building, department store, station yard, exhibition hall, tourist facility, or a vehicle that operates only during the day, when the toilet is not used at night This prevents bacteria from multiplying in the stagnant water in the toilet bowl and increasing the amount of urease to adhere to the surface of the toilet bowl, thereby preventing urine stones from adhering and also preventing a cause of unpleasant odor. During the day, tap water is flushed into the urinal A31 by the operation of the automatic toilet flushing system B31 or manually, independently of the operation of the toilet flushing device, every time the toilet is used or at a predetermined time interval. Since the surface of the toilet A31 is washed with water and the accumulated water in the toilet trap is replaced, bacteria do not grow in the accumulated water, and the amount of urease does not increase.

[0334] In this toilet bowl cleaning apparatus, the following may be performed. The control device 37 is connected to the automatic toilet flushing system B31 so that the signal from the control device 37 allows the automatic toilet flushing system B31 to perform normal toilet flushing. When the free chlorine-containing water is supplied only at night as described above, first, the control device 37 sends a cleaning signal to the automatic toilet flushing system B31 to flush the flushing water to the toilet. This displaces the stagnant water in the toilet bowl (which replaces about 99% of the stagnant water with fresh water) and removes most of the bacteria out of the toilet bowl. Thereafter, the controller 37 opens the flow control valve 35 as described above. As a result, free chlorine-containing water is generated as described above and flows to the toilet A31, and the remaining bacteria are sufficiently sterilized.

When the water containing free chlorine is allowed to flow only at night as described above, a high concentration or a large amount is flowed only at the first time of the night, and a lower concentration or a small amount of the free chlorine is used at the second and subsequent nights. The contained water may be allowed to flow. In order to increase the concentration of free chlorine-containing water, the opening of the flow control valve 35 may be reduced or the current flowing between the electrodes may be increased. To lower the concentration, conversely, the opening degree of the flow control valve 35 may be increased or the current flowing between the electrodes may be reduced. Also, in order to flow a large amount of free chlorine-containing water into the toilet, the above-mentioned `` predetermined water level higher than the height of the top of the electrode '' may be set higher, and in order to reduce the amount, the predetermined water level is lowered. Just set it.

In the toilet flushing apparatus of FIG. 4, the following may be performed. Connect the control device 37 and the flow control valve 35,
A timer is provided in the control device 37. The controller 37 is further connected to the automatic toilet bowl cleaning system B31, and an operation signal of the automatic toilet bowl cleaning system B31 is also input to the controller 37. The timer of the control device 37 is started by the operation signal of the automatic toilet flushing system B31, so that the control device 3
According to 7, when the toilet is not used within a certain time after the toilet is used, that is, the operation signal of the automatic toilet cleaning system B31 is not output within a predetermined time after the urinal A31 is used and the operation signal of the automatic toilet cleaning system B31 is output. In this case, based on the instruction of the timer, the control device 37 opens the flow control valve 35 so that the flow rate is adjusted to the predetermined value.
From the toilet flush water supply pipe 33 upstream of the water supply valve 34, the tap water with a small flow rate always flows into the water storage type electrolysis tank 31 through the first branch pipe 32 and the flow control valve 35. The water level in the water storage type electrolysis tank 31 is detected by the float sensor 38, and when the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, the control device 37 receives the detection signal from the float sensor 38. As a result, a voltage is applied between the electrodes, and the water stored in the water storage type electrolysis tank 31 is electrolyzed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 which has received the detection signal from the float sensor 38 opens the on-off valve 39 to generate the electrolysis. The free chlorine-containing water flows through the on-off valve 39 and the second branch pipe 36 to a position downstream of the water supply valve 34 of the toilet flush water supply pipe 33, and flows to the urinal A31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 39 is closed, and the flow control valve 35 is closed simultaneously or slightly later.

[0337] In this case, the free chlorine-containing water is flushed to the toilet A31 only when the toilet is not used within a certain period of time after the toilet is used. Urease is prevented from increasing and sticking to the surface of the toilet bowl, thereby preventing urine stones from adhering and preventing an unpleasant odor.

In the toilet flushing apparatus of FIG. 4, the following may be performed. Connect the control device 37 and the flow control valve 35,
A timer is provided in the control device 37. The control device 37 is also connected to the automatic toilet flushing system B31, and an operation signal of the automatic toilet flushing system B31 is also input to the control device 37.

When the water level in 1 reaches a predetermined value higher than the height of the top of the electrode, the opening / closing valve 39 is opened by the control device 37 which has received the detection signal from the float sensor 38, and the water containing free chlorine generated by the electrolysis is discharged. On-off valve 39 and second branch pipe 3
6 and flows into the toilet flushing water supply pipe 33 to a position downstream of the water supply valve 34 and flows to the urinal A31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 39 is closed, and the flow control valve 35 is closed simultaneously or slightly later.

In this manner, the water containing free chlorine can be flushed to the toilet while the toilet surface is wet after the toilet is washed by the automatic toilet washing system B31 after the toilet is used. Free chlorine-containing water diffuses widely on the surface. As a result, the toilet surface is effectively sterilized, and an increase in urease is prevented, so that the production of ammonia is effectively suppressed, and thus, the adhesion of urine stones is prevented, and a cause of an unpleasant odor is also prevented. .

In the toilet flushing apparatus of FIG. 4, the following may be performed. An on-off valve C is disposed on the first branch pipe 32 upstream of the flow control valve 35, a control device 37 is connected to the on-off valve C, and a timer is disposed on the control device 37. The flow control valve 35 is adjusted so as to always flow at a predetermined flow rate. The on-off valve C is opened as appropriate, and the first branch pipe 32, the on-off valve C and the flow control valve 3 are connected from the toilet flush water supply pipe 33 upstream of the water supply valve 34.
5 and a small flow of tap water is constantly stored in the electrolysis tank 3
So that it flows into 1. When the on-off valve 39 is opened, the water containing free chlorine generated by the electrolysis is turned on and off.
And the second branch pipe 36, flows into the toilet flush water supply pipe 33 to a position downstream of the water supply valve 34, and flows to the urinal A31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 39 is closed, and the on-off valve C is closed simultaneously or slightly later.

In this case, the first branch pipe 32 and the on-off valve C are connected from the toilet flush water supply pipe 33 upstream of the water supply valve 34.
After the tap water having a small flow rate always flows into the water storage type electrolysis tank 31 through the flow control valve 35 and the open / close valve 39, the open / close valve 39 is opened. And the second branch pipe 36, and flows into the toilet flush water supply pipe 33 to a position downstream of the water supply valve 34, and the urinal A
The operation during the flow in the stream 31 may be the same as described above.
That is, the water level in the water storage type electrolysis tank 31 is detected by the float sensor 38, and when the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, the control receiving the detection signal from the float sensor 38 A voltage is applied between the electrodes by the device 37, and the stored water in the water storage type electrolysis tank 31 is electrolyzed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 that has received the detection signal from the float sensor 38 opens the on-off valve 39.

By doing so, the on-off valve C can be opened only when necessary by the instruction of the timer, and the water containing free chlorine can flow into the urinal A31. Thus, the need for maintenance can be further reduced. In addition, the amount of water and electricity is reduced compared to the case of continuous flow, saving resources and
It is energy saving.

Further, the provision of the on-off valve C eliminates the need for flow control for each opening and closing, and eliminates the need to provide a flow control mechanism in the control device.

In the toilet bowl cleaning apparatus shown in FIG. 4, the following may be performed. An on-off valve C is disposed on the first branch pipe 32 upstream of the flow control valve 35, a control device 37 is connected to the on-off valve C, and a timer is disposed on the control device 37. The flow control valve 35 is adjusted so as to always flow at a predetermined flow rate. Open the on-off valve C only at night. From the toilet flush water supply pipe 33 upstream of the water supply valve 34, the tap water with a small flow rate always flows into the water storage type electrolysis tank 31 through the first branch pipe 32, the on-off valve C and the flow control valve 35. The water level in the water storage type electrolysis tank 31 is detected by the float sensor 38, and when the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, the control device 3 receives the detection signal from the float sensor 38.

When the water level in 1 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 that has received the detection signal from the float sensor 38 opens the on-off valve 39, and the free chlorine-containing water generated by the electrolysis is opened. Passes through the on-off valve 39 and the second branch pipe 36, and passes through the water supply valve 34 of the toilet flush water supply pipe 33.
It flows to a position further downstream and is flushed to the urinal A31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 39 is closed, and the on-off valve C is closed simultaneously or slightly later.

In this way, the water containing free chlorine is allowed to flow into the toilet A31 only at night.
When a toilet bowl is used only during the day and rarely used at night, such as a toilet installed in an office building, department store, station yard, exhibition hall, tourist facility, or a vehicle that operates only during the day, when the toilet is not used at night This prevents bacteria from multiplying in the stagnant water in the toilet bowl and increasing the amount of urease to adhere to the surface of the toilet bowl, thereby preventing urine stones from adhering and also preventing a cause of unpleasant odor. During the day, tap water is flushed into the urinal A31 by the operation of the automatic toilet flushing system B31 or manually, independently of the operation of the toilet flushing device, every time the toilet is used or at a predetermined time interval. Since the surface of the toilet A31 is washed with water and the accumulated water in the toilet trap is replaced, bacteria do not grow in the accumulated water, and the amount of urease does not increase. Further, the provision of the on-off valve C eliminates the need for flow control for each opening and closing, and eliminates the need to provide a flow control mechanism in the control device.

In the toilet flushing apparatus of FIG. 4, the following may be performed. An on-off valve C is provided in the first branch pipe 32 upstream of the flow control valve 35, and the control device 37 is connected to the on-off valve C. The flow control valve 35 is adjusted so as to always flow at a predetermined flow rate. A timer is provided in the control device 37, and the control device 37 is further connected to the automatic toilet flushing system B31,

If not output, on-off valve C
open. Toilet flushing water supply pipe 33 upstream of the water supply valve 34
Through the first branch pipe 32, the on-off valve C and the flow control valve 35, tap water with a small flow rate always flows into the water storage type electrolysis tank 31. The water level in the water storage type electrolysis tank 31 is detected by the float sensor 38, and when the water level in the water storage type electrolysis tank 31 reaches the height of the top of the electrode, the control device 37 receives the detection signal from the float sensor 38. As a result, a voltage is applied between the electrodes, and the water stored in the water storage type electrolysis tank 31 is electrolyzed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 37 which has received the detection signal from the float sensor 38 opens the on-off valve 39 to generate the electrolysis. The free chlorine-containing water flows through the on-off valve 39 and the second branch pipe 36 to a position downstream of the water supply valve 34 of the toilet flush water supply pipe 33, and flows to the urinal A31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 39 is closed, and the on-off valve C is closed simultaneously or slightly later.

[0347] In this way, the free chlorine-containing water is flushed to the toilet A31 only when the toilet is not used within a certain period of time after the toilet is used. However, it is possible to prevent a situation in which the amount of urease increases and adheres to the surface of the toilet bowl, thereby preventing urine stones from adhering and also preventing a cause of unpleasant odor. Further, the provision of the on-off valve C eliminates the need for flow control for each opening and closing, and eliminates the need to provide a flow control mechanism in the control device.

[0348] In the toilet cleaning device of Fig. 4, the following may be performed. An on-off valve C is provided in the first branch pipe 32 upstream of the flow control valve 35, and the control device 37 is connected to the on-off valve C. The flow control valve 35 is adjusted so as to always flow at a predetermined flow rate. A timer is provided in the control device 37, and the control device 37 is also connected to the automatic toilet flushing system B31, so that an operation signal of the automatic toilet flushing system B31 is also input to the control device 37. According to the operation signal of the automatic toilet flushing system B31, every time the toilet is flushed after using the toilet, that is, the urinal A31 is used and the automatic toilet flushing system B31 is used.
Each time the operation signal is output, the control device 37 opens the on-off valve C. From the toilet flush water supply pipe 33 upstream of the water supply valve 34 to the first branch pipe 32, the on-off valve C and the flow control valve 3
5, tap water with a small flow rate always flows into the water storage type electrolysis tank 31. The water level in the water storage type electrolysis tank 31 is detected by the float sensor 38 and the water storage type electrolysis tank 3
When the water level in the tank 1 reaches the height of the top of the electrode, a voltage is applied between the electrodes by the control device 37 which has received the detection signal from the float sensor 38, and the stored water in the water storage type electrolysis tank 31 is electrically operated. Decomposed. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value higher than the height of the top of the electrode, the control device 3 receiving the detection signal from the float sensor 38
7, the open / close valve 39 is opened, and the free chlorine-containing water generated by the electrolysis flows through the open / close valve 39 and the second branch pipe 36 to a position downstream of the water supply valve 34 of the toilet flush water supply pipe 33. Then, it is flushed to the urinal A31. When the water level in the water storage type electrolysis tank 31 reaches a predetermined value lower than the height of the top of the electrode, the on-off valve 39 is closed, and the on-off valve C is closed simultaneously or slightly later.

In this way, since the water containing free chlorine can be flushed into the toilet while the toilet surface is wet after the toilet is washed by the automatic toilet washing system B31 after using the toilet, the toilet that has been wet by the toilet wash can be used. Free chlorine-containing water diffuses widely on the surface. As a result, the toilet surface is effectively sterilized, and an increase in urease is prevented, so that the production of ammonia is effectively suppressed, and thus, the adhesion of urine stones is prevented, and a cause of an unpleasant odor is also prevented. .

FIG. 5 shows another embodiment of the toilet flushing apparatus according to the present invention.
2, the toilet flushing water supply pipe 43 is connected to a position upstream of a water supply valve 44 such as a flush valve. An on-off valve 45 is provided on the way of the first branch pipe 42. The water storage type electrolysis tank 41 is connected via a second branch pipe 46 to a position downstream of the water supply valve 44 of the toilet flush water supply pipe 43. An on-off valve 49 is provided on the way of the second branch pipe 46. The toilet flush water supply pipe 43 to which the second branch pipe 46 is connected is connected to the urinal A41. The control device 47 is connected to the electrode of the water storage type electrolysis tank 41, the float sensor 48, and the on-off valves 45 and 49.

In this toilet flushing apparatus, tap water flows from the toilet flushing water supply pipe 43 upstream of the water supply valve 44 through the first branch pipe 42 and the on-off valve 45 into the water storage type electrolysis tank 41. The water level in the water storage type electrolysis tank 41 is detected by a float sensor 48. When the water level in the water storage type electrolysis tank 41 reaches a predetermined value higher than the top of the electrode, the control device 47 that has received the detection signal from the float sensor 48 closes the on-off valve 45. The control device 47 is provided with a timer, and in a predetermined time zone, between the electrodes of the water storage type electrolysis tank 41, the water level in the water storage type electrolysis tank 41 reaches a predetermined value higher than the top of the electrode. Only in this case, a voltage is applied, and the water stored in the water storage type electrolysis tank 41 is electrolyzed. After the stored water in the water storage type electrolysis tank 41 is electrolyzed, the on-off valve 49 is promptly opened according to an instruction from the control device 47, and the free chlorine-containing water generated by the electrolysis is separated from the on-off valve 49 and the second branch. Through tube 46,
The water flows into the toilet flushing water supply pipe 43 at a position downstream of the water supply valve 44 and flows to the urinal A41.

Independently of the toilet flushing device, by the operation of the automatic toilet flushing system B41 or manually
Tap water is flushed to urinal A41 each time it is used, and urinal A
The surface of 41 is washed with water, and the water remaining in the toilet trap is replaced.

This toilet bowl washing apparatus, like the toilet bowl washing apparatus shown in FIGS. 1 to 4, requires less maintenance than a conventional washing apparatus in which chemicals are mixed into washing water, and is safe for the user. is there.

In the above apparatus, a voltage is appropriately applied to the electrodes in the water storage type electrolysis tank 41 in accordance with a timer instruction, so that the water containing free chlorine flows into the urinal A41. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented.

In the above-mentioned toilet bowl washing apparatus, a time zone in which a voltage can be applied between the electrodes of the water storage type electrolysis tank 41 may be provided at predetermined time intervals according to a timer instruction. In this manner, the toilet A41 is provided at predetermined time intervals.
Since the free chlorine-containing water is supplied to the electrode, the electrolysis is intermittently performed, the life of the electrode in the electrolyzer is improved, and the necessity of maintenance can be further reduced. Further, the amount of water and electricity is reduced as compared with the case where the water is constantly flushed, so that resources and energy are saved.

In the above-mentioned toilet bowl washing apparatus, a time zone in which a voltage can be applied between the electrodes of the water storage type electrolysis tank 41 only at night according to a timer instruction may be provided. In this way, the water containing free chlorine is flushed to the toilet A41 only at night, so that it is installed in, for example, office buildings, department stores, station premises, exhibition halls, tourist facilities, and vehicles such as vehicles operated only in the daytime. Like a toilet bowl,
In toilets that are used only in the daytime and hardly used at night, when the toilet is not used at night, bacteria can be prevented from growing in the water remaining in the toilet, increasing the amount of urease and sticking to the surface of the toilet, and consequently the adhesion of urine stones Is prevented, and a cause of an unpleasant odor is also prevented. In the daytime, every time the toilet is used or at a predetermined time interval, independently of the operation of the toilet cleaning device, by the operation of the automatic toilet cleaning system B41,
Alternatively, the tap water is flushed into the urinal A41 by hand, and the surface of the urinal A41 is washed with water and the accumulated water in the urinal trap is replaced. Therefore, bacteria do not grow in the accumulated water and the amount of urease does not increase. . In addition, the amount of water and electricity is reduced as compared with a case where the water is constantly flushed, so that resources and energy are saved.

In the toilet bowl cleaning apparatus, the following may be performed. The control device 47 is connected to the automatic toilet flushing system B41 so that the signal from the control device 47 allows the automatic toilet flushing system B41 to perform normal toilet flushing. Then, when the free chlorine-containing water is supplied only at night as described above, first, the control device 47 sends a cleaning signal to the automatic toilet flushing system B41 to cause the flushing water to flow into the toilet. This displaces the stagnant water in the toilet bowl (which replaces about 99% of the stagnant water with fresh water) and removes most of the bacteria out of the toilet bowl. Thereafter, the control device 47 opens the on-off valve 45 as described above. As a result, free chlorine-containing water is generated as described above and flows to the toilet A41, and the remaining bacteria are sufficiently sterilized.

When the water containing free chlorine is allowed to flow only at night as described above, a high concentration or a large amount is flowed only at the first time of the night, and a lower concentration or a small amount of free chlorine is used at the second and subsequent nights. The contained water may be allowed to flow. To increase the concentration of free chlorine-containing water, the current flowing between the electrodes may be increased, and to lower the concentration, the current flowing between the electrodes may be decreased. Also, in order to flow a large amount of free chlorine-containing water into the toilet, the above-mentioned `` predetermined water level higher than the height of the top of the electrode '' may be set higher, and in order to reduce the amount, the predetermined water level is lowered. Just set it.

In the above toilet flushing device, the following may be performed. The controller 47 is further equipped with an automatic toilet system B
The operation signal of the automatic toilet flushing system B41 is also input to the control device 47. When the timer of the control device 47 is started by the operation signal of the automatic toilet flushing system B41, the controller 47 does not use the toilet within a predetermined time after using the toilet, that is, the urinal A4
1 is used, and within a predetermined time after the operation signal of the automatic toilet flushing system B41 is output, the automatic toilet flushing system B4
When the operation signal of No. 1 is not output, a time zone in which a voltage can be applied is provided between the electrodes of the water storage type electrolysis tank 41 based on the instruction of the timer. Then, the free chlorine-containing water is flushed to the toilet A41 only when the toilet is not used within a certain time after the toilet is used, so that when the toilet is not used, bacteria proliferate in the stagnant water in the toilet and the amount of urease increases. As a result, it is possible to prevent the situation of sticking to the surface of the toilet bowl, thereby preventing the adhesion of urine stones and the cause of the unpleasant odor. In addition, the amount of water and electricity is reduced as compared with a case where the water is constantly flushed, so that resources and energy are saved.

In the above-mentioned toilet bowl washing apparatus, the following may be performed. The controller 47 is connected to the automatic toilet flushing system B41.
The operation signal of the automatic toilet flushing system B41 is also input to the control device 47. Toilet automatic cleaning system B4
In accordance with the operation signal of 1, every time the toilet is cleaned by the control device 47 after the toilet is used, that is, each time the urinal A41 is used and the operation signal of the automatic toilet cleaning system B41 is output, based on the instruction of the timer, A time zone in which a voltage can be applied is provided between the electrodes of the water storage type electrolysis tank 41. Then, since the free chlorine-containing water can be flushed into the toilet while the toilet surface is wet after the toilet is washed by the automatic toilet flushing system B41 after using the toilet, the free chlorine-containing water can be washed onto the toilet surface wet by the toilet wash. Spread widely.
As a result, the toilet surface is effectively sterilized, and an increase in urease is prevented, so that the production of ammonia is effectively suppressed, and thus, the adhesion of urine stones is prevented, and a cause of an unpleasant odor is also prevented. .

FIG. 6 (a) shows another embodiment of the toilet flushing apparatus according to the present invention, in which a water storage type electrolysis tank 51 having at least one pair of electrodes and a float sensor 58 is provided with a first branch pipe 52. It is connected to the toilet flushing water supply pipe 53 at a position upstream of a water supply valve 54 such as a flush valve. A flow control valve 55 is arranged on the way of the first branch pipe 52. The water storage type electrolysis tank 51 includes a second branch pipe 56.
Is connected to the toilet trap A52. An on-off valve 59 is disposed on the way of the second branch pipe 56. The control device 57 is connected to the electrode of the water storage type electrolysis tank 51, the float sensor 58 and the on-off valve 59.

In the toilet flushing apparatus, a small flow of tap water is constantly supplied from the flushing water supply pipe 53 upstream of the water supply valve 54 through the first branch pipe 52 and the flow control valve 55. It flows into the tank 51. The water level in the water storage type electrolysis tank 51 is detected by a float sensor 58. When the water level in the water storage type electrolysis tank 51 reaches the height of the top of the electrode, a voltage is applied between the electrodes by the control device 57 which has received the detection signal from the float sensor 58, and the water is stored in the water storage type electrolysis tank 51. Is electrolyzed. When the water level in the water storage type electrolysis tank 51 reaches a predetermined value higher than the height of the top of the electrode, the control device 57 that has received the detection signal from the float sensor 58 opens the on-off valve 59 to generate the electrolysis. The free water containing free chlorine is supplied to the on-off valve 59.
And the second branch pipe 56, and is flowed to the toilet trap A52. As a result, the accumulated water in the toilet A51 is appropriately sterilized, and the urease contained in the bacteria is removed together with the bacteria.
, The urine stones are prevented from being deposited in the toilet trap A52, which is the site where yellowish stains are most likely to adhere, and yellowish stains are prevented from being generated.

Independently of the operation of the toilet flushing apparatus, the tap water is flushed to the urinal A51 every time the toilet is flushed by the operation of the automatic toilet flushing system B51 or manually, and the surface of the urinal A51 is flushed. Then, the water retained in the toilet trap A52 is replaced.

[0364] In this toilet flushing device, as in the case of the toilet flushing device shown in Figs. 1 to 5, free chlorine-containing water as a toilet flushing solution is generated by electrolysis of tap water, so that conventional chemicals are mixed into the flushing water. The need for maintenance is less than that of a cleaning device to be used, and it is safe for the user.

In the above apparatus, by appropriately setting the flow rate of the flow rate control valve 55, free chlorine-containing water is caused to flow into the urinal A51 at predetermined time intervals. Therefore, the increase and fixation effect of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the decomposition of ammonia is suppressed, and adhesion of urine stone is prevented, and a cause of an unpleasant odor is also prevented. In addition, by intermittent electrolysis, the life of the electrodes in the electrolyzer can be improved, and the need for maintenance can be further reduced. Furthermore, the amount of water and electricity is saved as compared with the case of always flowing, so that resource and energy are saved.

In the toilet flushing device of FIG. 6A, the following may be performed. The control device 57 is connected to the flow control valve 55, and the control device 57 is provided with a timer. The flow rate control valve 55 is opened appropriately so that the flow rate is adjusted to a predetermined value. From the toilet flushing water supply pipe 53 upstream of the water supply valve 54, the tap water with a small flow rate always flows into the water storage type electrolysis tank 51 through the first branch pipe 52 and the flow control valve 55. The on-off valve 59 is opened, and the free chlorine-containing water generated by the electrolysis flows through the on-off valve 59 and the second branch pipe 56 to the toilet trap A52. The on-off valve 59 is closed when the water level in the water storage type electrolysis tank 51 reaches a predetermined value lower than the height of the top of the electrode, and the flow control valve 55 is closed at the same time or with a slight delay. .

In this case, a small flow rate of tap water is always supplied from the toilet flush water supply pipe 53 upstream of the water supply valve 54 to the storage type electrolysis tank 51 through the first branch pipe 52 and the flow control valve 55. After the inflow, the open / close valve 59 is opened, and the operation while the free chlorine-containing water generated by the electrolysis is passed through the open / close valve 59 and the second branch pipe 56 to the toilet trap A52 is the same as described above. What should I do? That is, the water level in the water storage type electrolysis tank 51 is detected by the float sensor 58, and when the water level in the water storage type electrolysis tank 51 reaches the height of the top of the electrode, the control receiving the detection signal from the float sensor 58 is performed. A voltage is applied between the electrodes by the device 57, and the stored water in the water storage type electrolysis tank 51 is electrolyzed. When the water level in the water storage type electrolysis tank 51 reaches a predetermined value higher than the height of the top of the electrode, the control device 57 that has received the detection signal from the float sensor 58 causes the on-off valve 59 to open.
Is opened.

By doing so, the flow control valve 55 can be opened only when necessary by the instruction of the timer, and the water containing free chlorine can flow into the toilet trap A52, so that the life of the electrodes in the electrolyzer can be improved. In addition, the need for maintenance can be further reduced. Furthermore,
Since the amount of water and electricity is saved as compared with the case where the power is always supplied, resources and energy are saved.

In the toilet flushing device of FIG. 6A, the following may be performed. The control device 57 is connected to the flow control valve 55, and the control device 57 is provided with a timer. The flow control valve 55 is opened only at night so that the flow rate is adjusted to a predetermined value. Then, from the toilet flush water supply pipe 53 upstream of the water supply valve 54, the first branch pipe 52 and the flow control valve 55 pass through,
Tap water with a small flow rate always flows into the water storage type electrolysis tank 51. The water level in the water storage type electrolysis tank 51 is detected by a float sensor 58, and when the water level in the water storage type electrolysis tank 51 reaches the height of the top of the electrode, the float sensor 58 is detected.
The voltage is applied between the electrodes by the control device 57 which has received the detection signal from, and the stored water in the water storage type electrolysis tank 51 is electrolyzed. When the water level in the water storage type electrolysis tank 51 reaches a predetermined value higher than the height of the top of the electrode, the control device 57 that has received the detection signal from the float sensor 58
The on-off valve 59 is opened, and the water containing free chlorine generated by the electrolysis is passed through the on-off valve 59 and the second branch pipe 56 to the toilet trap A52.

So that the production of ozone-containing water by
Since live bacteria are intermittently killed and removed, it is possible to effectively prevent the growth and fixation of live bacteria adhering to the toilet from outside air or the like. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented.

[0407] In this toilet bowl cleaning device, the control device 87 opens the on-off valve 85 only at night based on the instruction of the timer, and simultaneously or slightly delays the opening and closing of the on-off valve 85 by the control device 87. When the generation of ozone-containing water by the water generator 81 is started, for example, an office building, a department store, a station yard, an exhibition hall, a tourist facility, or a toilet installed in a toilet such as a vehicle that operates only in the daytime can be used. Thus, in a toilet that is used only in the daytime and is hardly used at night, when the toilet is not used at night, bacteria can be prevented from growing in the stagnant water in the toilet, increasing the amount of urease and sticking to the surface of the toilet, and thus preventing urination. The stones are prevented from adhering, and one of the causes of the unpleasant odor is also prevented. During the day,

Similarly to the above, when the toilet is not in use, bacteria are prevented from growing in the stagnant water in the toilet, and urease is prevented from increasing and sticking to the toilet surface. The cause is also prevented. When using the urinal, tap water is flushed into the urinal A81 by the operation of the automatic urinal cleaning system B81 or manually, independently of the operation of the urinal cleaning device, every time the urinal is used.
Since the surface of 81 is washed with water and the accumulated water in the toilet trap is replaced, bacteria do not grow in the accumulated water and urease does not increase.

Simultaneously with or slightly after opening of the on-off valve 85, the control device 87 causes the ozone-containing water generator 81 to start generating ozone-containing water. As a result, the ozone-containing water is supplied to the toilet bowl along with the supply of urea, thereby being sterilized.
The generation of ammonia is effectively suppressed, and thus the adhesion of urine stones is prevented, and at the same time, the cause of the unpleasant odor is also prevented.

[0411] If the on-off valve 85 is opened with a slight delay, the ozone-containing water flows into the toilet immediately before or immediately after the end of toilet cleaning after the toilet is used. The ozone-containing water diffuses widely on the surface of the toilet that is wet by the toilet flushing. As a result, the toilet surface is effectively sterilized, and an increase in urease is prevented, so that the production of ammonia is effectively suppressed, and thus, the adhesion of urine stones is prevented, and a cause of an unpleasant odor is also prevented. .

It is connected to urinal A111. The control device 117 is connected to the float sensor 118, the flow control valve 115, and the on-off valve 119 of the ozone-containing water generator 111.

In the toilet bowl washing apparatus, the water supply valve 114
To the first branch pipe 1
A small flow of tap water always flows into the ozone-containing water generator 111 through the flow control valve 12 and the flow control valve 115. The water level in the ozone-containing water generator 111 is detected by a float sensor 118. When the water level in the ozone-containing water generator 111 reaches a predetermined position, the control device 117 that has received a detection signal from the float sensor 118 causes the flow control valve 11
5 is closed, and the stored water in the ozone-containing water generator 111 is generated as ozone-containing water. After the ozone-containing water is generated, the control device 117 opens the on-off valve 119, and the generated ozone-containing water is supplied to the on-off valve 119 and the second branch pipe 1.
16 and flows into the toilet flushing water supply pipe 113 downstream of the water supply valve 114 and flows to the urinal A111.

Here, the time when the water level in the ozone-containing water generator reaches a predetermined position may be detected by directly measuring the water level with the float sensor 118 as described above, or the open / close valve is opened. The detection may be performed by measuring the passage of time from the time point.

Independently of the operation of the toilet flushing device, tap water is supplied to the toilet A111 every time the toilet flushing system B111 is operated or manually by operating the toilet flushing system B111.
The surface of the toilet A111 is washed with water, and the water remaining in the toilet trap is replaced.

[0430] Also in this toilet flushing device, the ozone-containing water, which is a toilet flushing liquid, is generated by an ozone-containing water generator by use of silent discharge or electric treatment by electrolysis of water. It requires less maintenance than a cleaning device that mixes chemicals into cleaning water, and is safe for the user.

[0431] In the above apparatus, by appropriately setting the flow rate of the flow control valve 115, the ozone-containing water is caused to flow into the toilet A111 at predetermined time intervals. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented. In addition, since the generation of ozone-containing water is performed intermittently, the amount of water and electricity is reduced as compared with a case where the ozone-containing water is constantly supplied, so that resource and energy are saved.

[0432] In the toilet cleaning apparatus of Fig. 12, the following may be performed. A timer is provided in the control device 117 connected to the flow control valve 115. Appropriate flow control valve 115

The on-off valve 119 is closed when the water level in the ozone-containing water generator 111 reaches a predetermined lower value, and the flow control valve 115 is closed simultaneously or slightly later.

In this case, a small flow of tap water is always supplied to the ozone-containing water generator 111 from the toilet flush water supply pipe 113 upstream of the water supply valve 114 through the first branch pipe 112 and the flow control valve 115. After the inflow, the on-off valve 119 is opened, and the generated ozone-containing water flows into the toilet flushing water supply pipe 113 downstream of the water supply valve 114 through the on-off valve 119 and the second branch pipe 116, The operation while flowing into A111 may be the same as described above. That is, the water level in the ozone-containing water generator 111 is
8, when the water level in the ozone-containing water generator 111 reaches a predetermined position, the flow control valve 115 is closed by the control device 117 that has received the detection signal from the float sensor 118. The stored water in the ozone-containing water generator 111 is generated as ozone-containing water. After the ozone-containing water is generated, the control device 117 causes the on-off valve 119 to be opened.

[0434] By doing so, the flow control valve 115 can be opened only when necessary according to the instruction of the timer, and the ozone-containing water can be flown into the toilet A111. Since the amount is saved, resources and energy are saved.

[0435] In the toilet flushing apparatus of Fig. 12, the following may be performed. The control device 117 and the flow control valve 115 are also connected, and a timer is provided in the control device 117 so that the flow control valve 115 is opened only at night to adjust the flow rate to a predetermined flow rate.

When the toilet is not used within a certain period of time after using the toilet, that is, when the toilet A111 is used and the activation signal of the automatic toilet cleaning system B111 is output, the timer of the control device 117 is started by the operation signal of If the operation signal of the automatic toilet bowl cleaning system B111 is not output within the
The flow control valve 115 is opened by 17 so that the flow rate is adjusted to a predetermined value. As a result, a small flow rate of tap water always flows into the ozone-containing water generator 111 from the toilet flush water supply pipe 113 upstream of the water supply valve 114 through the first branch pipe 112 and the flow control valve 115. Further, the on-off valve 119 is opened, and the generated ozone-containing water flows into the toilet flushing water supply pipe 113 downstream of the water supply valve 114 through the on-off valve 119 and the second branch pipe 116, and flows into the toilet A111. Swept away. When the water level in the ozone-containing water generator 111 reaches a predetermined low value, the on-off valve 119 is closed, and the flow control valve 115 is closed simultaneously or slightly later.

[0438] This prevents bacteria from multiplying in the stagnant water in the toilet when the toilet is not used, increasing the amount of urease and sticking to the surface of the toilet, and thereby preventing the adhesion of urine stones. The cause of the off-flavor is also prevented.
When using the toilet, tap water is flushed into the urinal A111 by the operation of the automatic toilet flushing system B111 or manually, independently of the operation of the toilet flushing device, every time the toilet is used, and the surface of the urinal A111 Is washed with water and the accumulated water in the toilet trap is replaced, so that bacteria do not grow in the accumulated water and urease does not increase.

As a result, a small flow rate of tap water always flows into the ozone-containing water generator 111 from the toilet flush water supply pipe 113 upstream of the water supply valve 114 through the first branch pipe 112 and the flow control valve 115. Further, the on-off valve 119 is opened, and the generated ozone-containing water flows into the toilet flushing water supply pipe 113 downstream of the water supply valve 114 through the on-off valve 119 and the second branch pipe 116, and flows into the toilet A111. Swept away. When the water level in the ozone-containing water generator 111 reaches a predetermined low value, the on-off valve 119 is closed, and the flow control valve 115 is closed simultaneously or slightly later.

In this manner, after the toilet is washed by the automatic toilet washing system B111 after using the toilet, the ozone-containing water can be flowed into the toilet while the toilet surface is wet. Ozone-containing water diffuses widely. As a result, the toilet surface is effectively sterilized, and an increase in urease is prevented, so that the production of ammonia is effectively suppressed, and thus, the adhesion of urine stones is prevented, and a cause of an unpleasant odor is also prevented. .

[0465] Also in this toilet flushing device, ozone-containing water as a toilet flushing liquid is generated by an ozone-containing water generator by use of silent discharge or electric treatment by electrolysis of water. Maintenance is less necessary than a cleaning device that mixes chemicals into cleaning water, and is safe for the user.

In the above device, by appropriately setting the flow rate of the flow control valve 135, the ozone-containing water is caused to flow into the toilet trap A132 at predetermined time intervals. Therefore, the increase and fixation effects of urease based on the action of viable bacteria are effectively suppressed, the increase in pH due to the dissolution of ammonia is suppressed, and adhesion of urine stones is prevented, and at the same time, one cause of unpleasant odor is also prevented. In addition, by performing the generation of ozone-containing water intermittently, the amount of water and electricity is reduced as compared with the case where the ozone-containing water is constantly flown, thereby saving resources and energy.

In the toilet flushing apparatus of FIG. 14, the following may be performed. The controller 137 is also connected to the flow control valve 135, and the controller 137 is provided with a timer. After the flow rate control valve 135 is opened at an appropriate opening and adjusted to a predetermined flow rate, the water passes through the first branch pipe 132 and the flow rate control valve 135 from the toilet flush water supply pipe 133 upstream of the water supply valve 134. The tap water with a small flow rate always has an ozone-containing water generator 1

When the water level in the ozone-containing water generator 131 reaches a predetermined lower value, the on-off valve 139 is closed, and the flow control valve 135 is closed simultaneously or slightly later.

In this case, a small flow rate of tap water is always supplied to the ozone-containing water generator 131 from the toilet flush water supply pipe 133 upstream of the water supply valve 134 through the first branch pipe 132 and the flow control valve 135. After the inflow, the on-off valve 139 is opened, and the generated ozone-containing water flows through the on-off valve 139 and the second branch pipe 136 to the toilet trap A132, and the operation is the same as described above. Good. That is,
The water level in the ozone-containing water generator 131 is detected by the float sensor 138, and when the water level in the ozone-containing water generator 131 reaches a predetermined position, the flow rate is controlled by the control device 137 which receives the detection signal from the float sensor 138. The valve 135 may be closed, the stored water in the ozone-containing water generator 131 may be generated as ozone-containing water, and after the ozone-containing water is generated, the control device 137 may open the on-off valve 139.

[0469] By doing so, the flow control valve 135 can be opened only when required by the instruction of the timer, and the ozone-containing water can be flown into the toilet trap A132. Resource saving and energy saving.

[0470] In the toilet flushing apparatus of Fig. 14, the following may be performed. The control device 137 is also connected to the flow control valve 135, and a timer is provided in the control device 137 to open the flow control valve 135 only at night so that the flow rate is adjusted to a predetermined flow rate. Thereby, the tap water having a small flow rate always flows into the ozone-containing water generator 131 from the toilet flush water supply pipe 133 upstream of the water supply valve 134 through the first branch pipe 132 and the flow control valve 135. Become. When the on-off valve 139 is opened, the generated ozone-containing water flows into the toilet trap A 132 through the on-off valve 139 and the second branch pipe 136. The on-off valve 139 is closed when the water level in the ozone-containing water generator 131 reaches a predetermined lower value, and the flow control valve 135 is closed simultaneously or slightly later.

In this way, the ozone-containing water flows to the toilet trap A 132 only at night,
For example, toilets used only in the daytime and hardly used at night, such as toilets installed in office buildings, department stores, station premises, exhibition halls, tourist facilities, vehicles operated only during the daytime, etc. When not in use, bacteria can be prevented from growing in the stagnant water in the toilet bowl, increasing the amount of urease and sticking to the surface of the toilet bowl, thereby preventing urine stones from adhering and also preventing a cause of unpleasant odor. In the daytime, each time the toilet is used or at predetermined time intervals, independently of the operation of the toilet cleaning device, the automatic toilet cleaning system B
Urinal A131 by actuation of 131 or manually
Tap water is flushed, the surface of urinal A131 is washed with water,
Since the stagnant water in the toilet trap A132 is replaced, bacteria do not grow in the stagnant water and urease does not increase.

[0472] In the toilet flushing apparatus of Fig. 14, the following may be performed. Control device 1 connected to flow control valve 135
At 37, a timer is provided. The control device 137 is further connected to the automatic toilet bowl cleaning system B131, and an operation signal of the automatic toilet bowl cleaning system B131 is input to the control device 137. The timer of the control device 137 is started by the operation signal of the automatic toilet flushing system B131, and when the toilet is not used within a certain time after the use of the toilet, that is, the toilet A131 is used and the automatic toilet flushing system B131 is used.
If the operation signal of the automatic toilet bowl washing system B131 is not output within a predetermined time after the operation signal of the above is output, the flow control valve 135 is opened by the control device 137 based on the instruction of the timer, and the flow rate is adjusted to the predetermined flow rate. To As a result, the tap water with a small flow rate always flows through the ozone-containing water generator 131 from the toilet flush water supply pipe 133 upstream of the water supply valve 134 through the first branch pipe 132 and the flow control valve 135.
To flow into When the on-off valve 139 is opened, the generated ozone-containing water is supplied to the on-off valve 139 and the second branch pipe 1.
When the water level in the ozone-containing water generator 131 reaches a predetermined lower value, the on-off valve 139 of the second branch pipe 139 is closed. Further, the flow control valve 135 of the first branch pipe 133 may be closed at the same time or with a slight delay.

[0473] This prevents bacteria from multiplying in the stagnant water in the toilet when the toilet is not in use and increasing the amount of urease to adhere to the surface of the toilet, thereby preventing urine stones from adhering. The cause of the off-flavor is also prevented.
At the time of using the toilet, the tap water is flushed to the urinal A131 each time the toilet is automatically used, independently of the operation of the toilet flushing device, by the operation of the automatic toilet flushing system B131 or manually, and the surface of the urinal A131 is washed. Since the stagnant water is flushed and the stagnant water in the toilet trap A132 is replaced, bacteria do not grow in the stagnant water and urease does not increase.

[0481] In this manner, when the toilet is not used, bacteria can be prevented from growing in the stagnant water in the toilet, increasing the amount of urease and sticking to the surface of the toilet, thereby preventing urine stones from adhering. The cause of the off-flavor is also prevented.
At the time of using the toilet, the tap water is flushed to the urinal A131 each time the toilet is automatically used, independently of the operation of the toilet flushing device, by the operation of the automatic toilet flushing system B131 or manually, and the surface of the urinal A131 is washed. Since the stagnant water is flushed and the stagnant water in the toilet trap A132 is replaced, bacteria do not grow in the stagnant water and urease does not increase. In addition, by providing the on-off valve H, the flow control for each opening and closing becomes unnecessary, and the control device does not need to be provided with a flow control mechanism.

FIG. 15 shows another embodiment of the toilet flushing apparatus according to the present invention. It is connected to a position upstream of the water supply valve 144 composed of a flash valve or the like. On-off valve 1
45 is provided in the middle of the first branch pipe 142. The ozone-containing water generator 141 is connected via the second branch pipe 146 to
It is connected to toilet trap A142. On-off valve 149
Is provided on the way of the second branch pipe 146. The control device 142 is connected to the ozone-containing water generator 141 and the on-off valves 145 and 149.

In the toilet flushing apparatus, the water supply valve 144 is provided.
To the first branch pipe 1
Tap water flows into the ozone-containing water generator 141 through the valve 42 and the on-off valve 145. The water level in the ozone-containing water generator is detected by the float sensor 148. When the water level in the ozone-containing water generator 141 reaches a predetermined position, the control device 1 receives a detection signal from the float sensor 148.
By 47, the on-off valve 145 is closed. Control device 14
7 is provided with a timer, and the ozone-containing water is generated only when the stored water in the ozone-containing water generator 141 is equal to or more than a predetermined value in a predetermined time zone. After the ozone-containing water is generated, the on-off valve 149 is promptly opened according to an instruction from the control device 147, and the generated ozone-containing water passes through the on-off valve 149 and the second branch pipe 146, and passes through the urinal trap A142. Is washed away.

The time when the water level in the ozone-containing water generator reaches a predetermined position is determined by the float sensor 1 as described above.
The detection may be performed by directly measuring the water level by using 48, or by measuring the lapse of time from when the on-off valve 145 of the first branch pipe 142 or the on-off valve 149 of the second branch pipe 146 is opened. May be.

[0485] Independently of the operation of the toilet flushing device, tap water is flushed into the toilet A141 every time it is used, by the operation of the automatic toilet flushing system B141 or manually.
The surface of the toilet A141 is washed with water, and the toilet trap A142 is washed.
The stagnant water inside is replaced.

[0486] Also in this toilet flushing device, ozone-containing water as a toilet flushing liquid is generated by an ozone-containing water generator by silent discharge use or electric treatment by electrolysis of water. Maintenance is less necessary than a cleaning device that mixes chemicals into cleaning water, and is safe for the user.

In the above apparatus, ozone-containing water is generated as appropriate according to the instruction of the timer, and is supplied to the toilet trap A142. Therefore, an increase in urease based on the action of live bacteria,
The sticking effect is effectively suppressed, and p
The increase in H is suppressed to prevent the adhesion of urine stone, and also to prevent a cause of an unusual odor.

[0488] In the above-mentioned toilet bowl washing device, a time zone in which ozone-containing water is generated may be provided at predetermined time intervals according to a timer instruction. By doing so, the ozone-containing water is caused to flow into the toilet trap A142 at predetermined time intervals, so that water and electricity are saved, and resources and energy are saved as compared with a case where the water is always flown.

[0489] In the above-mentioned toilet bowl washing apparatus, a time zone in which ozone-containing water is generated only at nighttime according to a timer instruction may be provided. In this case, the ozone-containing water flows into the toilet trap A142 only at night, so that the ozone-containing water is supplied to, for example, office buildings, department stores, station premises, exhibition halls, tourist facilities, and vehicles such as vehicles operated only in the daytime. In toilets that are used only in the daytime and are hardly used at night, such as installed toilets, bacteria proliferate in the water remaining in the toilet when the toilet is not used at night, and the amount of urease increases and sticks to the surface of the toilet. This prevents the adhesion of urine stones and, at the same time, prevents the cause of unpleasant odor. During the day, tap water is flushed into the urinal A141 by the operation of the automatic toilet flushing system B141 or manually, independently of the operation of the toilet flushing device, every time the toilet is used or at a predetermined time interval, Urinal A141
Of the toilet bowl is flushed, and the accumulated water in the toilet trap A142 is replaced, so that bacteria do not grow in the accumulated water.
Urease does not increase.

[0490] In the above toilet bowl cleaning apparatus, the following may be performed. The control device 147 is further connected to the automatic toilet bowl cleaning system B141, and an operation signal of the automatic toilet bowl cleaning system B141 is input to the control device 147. The timer of the control device 147 is started by the operation signal of the automatic toilet flushing system B141, and when the toilet is not used within a predetermined time after using the toilet, that is, the operation signal of the automatic toilet flushing system B141 is output using the toilet A141. When the operation signal of the automatic toilet flushing system B141 is not output within a predetermined time after the operation, the controller 147 sets a time zone in which the ozone-containing water is generated based on the instruction of the timer. In this way, the ozone-containing water is flushed to the toilet trap A142 only when the toilet is not used within a certain time after the toilet is used, so that bacteria can multiply in the stagnant water in the toilet when the toilet is not used, and urease Is prevented from increasing and sticking to the surface of the toilet, thereby preventing urine stones from adhering and preventing one of the causes of unpleasant odor. At the time of using the toilet, the tap water is flushed to the urinal A141 every time by using the automatic toilet flushing system B141 or manually, independently of the operation of the urinal A, and the surface of the urinal A141 is washed. Since the water is washed and the accumulated water in the toilet trap A142 is replaced, bacteria do not grow in the accumulated water, and the amount of urease does not increase.

(Example 1) As shown in FIG. 16, tap water was introduced into a non-diaphragm type continuous electrolysis tank having a flat electrode, and a titanium plate coated with an iridium oxide-platinum catalyst was coated with chlorine. Tap water is electrolyzed using the generating electrode, and free chlorine-containing water generated by the electrolysis is passed through the urinal through a separate pipe from the urinal washing pipe system, and bacteria in the urinal trap retained water are discharged. Number, urinal trap stagnant water pH,
An effect confirmation test was conducted to investigate the surface dirt on the urinal trap.

[0492] In the test, the urinals of Fig. 16 were supplied with free chlorine-containing water having different concentrations at different flowing frequencies, and the urinals were not washed with the free chlorine-containing water. Normal flushing was performed every time the urinal was used. Table 1 shows the test conditions. This urinal is rarely used at night because it is installed in the company.

[0493]

[Table 1]

Table 2 shows the number of bacteria in the urinal trap retained water at 0.5 months after the start of the test, and FIG. 17 shows the pH of the urinal trap retained water.

[0495]

[Table 2]

According to the urinal data shown in Table 2 and FIG. 17, the urinal is not used compared to the daytime when the urinal is used and the ordinary flushing is performed, and the water retained in the urinal trap is replaced. Therefore, during the night when the normal flushing is not performed and the retained water in the urinal trap is not replaced, the number of bacteria in the urinal trap retained water grows, urease increases, and the pH in the urinal trap retained water may increase. Recognize. Therefore, it is considered that the adhesion of urine stones to the urinal also proceeds at night.

[0497] Table 2 shows that the concentration of free chlorine (weight concentration in terms of chlorine atom) obtained by electrolyzing tap water is 0.1 to 3 mg / liter based on the data of urinals ~ in Fig. 17. It can be seen that by flowing water through the urinal, the urinal trap stagnant water is sterilized, and the pH of the urinal trap stagnant water decreases.

After the test in Table 1 was continued for one month, the trap from the urinal was taken out and the surface was observed. No staining or urinary stone adhesion was observed on the toilet ~.

In the urinal, the urinal trap stagnant water is sterilized, and the urinal trap stagnant water has a pH value.
The urine is not used, normal flushing is not performed, and the water remaining in the urinal trap is not replaced. It is considered that the growth of bacteria in the urinal trap stagnant water, that is, an increase in urease, can be prevented, and an increase in the pH of the urinal trap stagnant water and, consequently, the adhesion of urine to the urinal can be suppressed.

From the data of the urinal shown in Table 2 and FIG. 17, during the daytime, the water remaining in the urinal trap is replaced by ordinary washing after use, and the growth of bacteria in the urinal trap water is suppressed. Therefore, it can be seen that there is no difference in the number of bacteria in the urinal trap stagnant water and the pH of the urinal trap stagnant water whether the free chlorine-containing water flows into the urinal or not. Therefore, it is considered that the necessity of flowing free chlorine-containing water into the urinal during the daytime when the toilet is used is low.

From the data of the urinal shown in Table 2 in FIG. 17, it can be seen that the water content between the free chlorine-containing water having a free chlorine concentration of 3 mg / liter and the free chlorine-containing water having a free chlorine concentration of 0.5 mg / liter is small. It can be seen that there is almost no difference in the bactericidal effect against bacteria in the urinal trap stagnant water and the pH increase suppressing effect in the urinal trap stagnant water. Furthermore, a sterilizing effect on bacteria in the urinal trap retained water between the free chlorine-containing water having a free chlorine concentration of 3 mg / liter and the free chlorine-containing water having a free chlorine concentration of 0.1 mg / liter, the urinal trap retained water, It can be seen that there is no significant difference in the effect of suppressing the increase in pH.

[0502] Therefore, it is considered that if free chlorine-containing water having a free chlorine concentration of 0.1 mg / liter is allowed to flow into the toilet, the adhesion of urine stones to the urinal can be suppressed.

(Example 2) As shown in Fig. 16, tap water was introduced into a non-diaphragm type continuous electrolysis tank having a flat electrode, and chlorine was coated on a titanium plate with an iridium oxide-platinum catalyst. Tap water is electrolyzed using the generating electrode, and free chlorine-containing water generated by the electrolysis is passed through the urinal through a separate pipe from the urinal washing pipe system, and bacteria in the urinal trap retained water are discharged. Number, urinal trap stagnant water pH,
An effect confirmation test was conducted to investigate the surface dirt on the urinal trap.

[0504] However, in Example 1, the water containing free chlorine generated by the electrolysis was immediately flushed into the urinal. After that, the water containing free chlorine generated by the electrolysis was allowed to flow into the urinal.

The test was carried out using the urinal of FIG. 16. The urine was supplied with free chlorine-containing water having different concentrations at different time intervals, and the urinal was supplied with the free chlorine. No water washes were performed. Normal flushing was performed every time the urinal was used. Table 3 shows the test conditions. This urinal is rarely used at night because it is installed in the company.

[0506]

[Table 3]

Table 4 shows the number of bacteria in the urinal trap water at 0.5 months after the start of the test, and FIG. 18 shows the pH of the urinal trap water. The number of bacteria in the urinal trap stagnant water was measured at 7:40 am

[0508]

[Table 4]

From the data of the urinal of Table 4 and FIG. 18, the concentration of free chlorine (weight concentration in terms of chlorine atom) obtained by electrolyzing tap water is 0.02 to 0.5 m.
It can be seen that by flowing g / liter of free chlorine-containing water through the urinal, the urinal trap stagnant water is sterilized, and the pH of the urinal trap stagnant water decreases.

After the test in Table 3 was continued for one month, the trap from the urinal was taken out and the surface was observed. As a result, stains and stains of urine were observed on the urinal. No staining or urinary stone adhesion was observed on the toilet ~.

In this experiment, the free chlorine concentration was 0.02 mg /
The effect was caused by flowing a liter of free chlorine-containing water through the urinal, which is presumably because the number of bacteria in the retained water was reduced in advance by replacing the retained water immediately before.

(Example 3) In order to examine the effect on the toilet, the following two experiments were performed.

Experiment 1 The toilet was used normally, and the appearance of dirt was observed. There were no colored stains on the initial ball surface. However, after two weeks, as shown in FIG. 19 (a), a pink ring-shaped stain occurs on the draft surface, and after four weeks, as shown in FIG. Vertical streak-like dirt radiated in the flowing water direction.

Experiment 2 The toilet was used normally, and water containing free chlorine generated by electrolysis was applied to the toilet twice a day at 8:00 am and 11:00 pm. The method of applying free chlorine-containing water generated by electrolysis to a toilet bowl is to introduce tap water to a non-diaphragm type continuous electrolysis tank having a flat electrode, and coat an iridium oxide-platinum catalyst on a titanium plate. The tap water is electrolyzed using the chlorine-generating electrode thus obtained, and the resulting free chlorine-containing water is applied to a half-perimeter of the ball surface near the hole at the lower part of the toilet rim where the toilet flush water is discharged ( (FIG. 20). There were no colored stains on the initial ball surface.
After a lapse of 4 weeks, as shown in FIG. 21, on the rim portion of the ball surface on which the free chlorine-containing water was not applied, dirt in the form of vertical stripes was radially formed in the flowing water direction. On the other hand, no stain was observed on the half surface to which the water containing free chlorine was applied. Also,
No pink ring-shaped stains on the water surface observed in Experiment 1 were observed.

[0515] From Experiments 1 and 2, it was found that by flowing free chlorine-containing water obtained by electrolysis, it was also possible to prevent colored stains on the toilet.

Here, the reason why the vertical streak-like dirt is radially applied to the rim portion of the ball surface in the flowing water direction is that the discharge hole of the toilet flush water discretely provided at the lower part of the rim portion substantially corresponds to the dirt position. Therefore, it is considered that moisture is always supplied to this part, and the bacteria easily propagate. Therefore, when flowing the free chlorine-containing water obtained by the electrolysis into the toilet, it is preferable to flow the water from the same position as the discharge hole of the toilet flush water. For that purpose, it can be said that it is preferable to flow from the toilet flush water supply pipe to the toilet.

Example 4 As shown in FIG. 22, tap water was led to an ozone-containing water generator to generate ozone-containing water, which was generated via a pipe separate from the urinal flush pipe system. Ozone-containing water was flowed into the urinal, and an effect confirmation test was conducted to investigate the number of bacteria in the urinal trap stagnant water and the surface contamination of the urinal trap.

In the test, the urinals in FIG. 22 were supplied with different concentrations of ozone-containing water at different flowing frequencies, and the urinals were not washed with the ozone-containing water. Normal flushing was performed every time the urinal was used. Table 5 shows the test conditions.

[0519]

[Table 5]

Table 6 shows the bacterial count in the urinal trap residence water at 0.5 months after the start of the test.

[0521]

[Table 6]

[0522] From the urinal data in Table 6, the urinal is not used because the urinal is used and normal flushing is performed, and the urinal is not used as compared with the daytime when the water retained in the urinal trap is replaced. It can be seen that the number of bacteria in the urinal trap retained water multiplies and urease increases during the night when the water retained in the urinal trap is not replaced by flushing. Therefore,
The adhesion of urinary stones to the urinal is also thought to progress at night.

Based on the data of the urinal of Table 6 and FIG. 22, the ozone-containing water having a generated ozone concentration of 0.01 to 0.1 mg / liter is passed through the urinal to sterilize the water retained in the urinal trap. It is understood that it is done.

After continuing the test in Table 5 for one month, the trap from the urinal was removed and the surface was observed.
In the urinal, colored stains and urine stones were observed, whereas in the urinals ~, no stains and urine stones were observed.

In the urinal, since the accumulated water in the urinal trap is sterilized and no yellowish stain is observed, the urinal is not used, ordinary washing is not performed, and the accumulated water in the urinal trap is not replaced. By flowing ozone-containing water into the urinal at night, the growth of bacteria in the urinal trap stagnant water, that is, the increase in urease, is prevented,
It is considered that the adhesion of urine stones to the urinal can be suppressed.

According to the data of the urinal shown in Table 6 and FIG. 22, in the daytime, the accumulated water in the urinal trap is replaced by ordinary washing after use, and the growth of bacteria in the urinal trap accumulated water is suppressed. Therefore, it can be seen that there is no difference in the number of bacteria in the urinal trap stagnant water whether or not the ozone-containing water flows into the urinal. Therefore, it is considered that the necessity of flowing the ozone-containing water to the urinal in the daytime when the toilet is used is low.

From the data of the urinal in Table 6, FIG. 22, the urinal trap is located between the ozone-containing water having an ozone concentration of 0.1 mg / liter and the ozone-containing water having an ozone concentration of 0.05 mg / liter. It can be seen that there is almost no difference in the bactericidal effect on bacteria in the stagnant water. Further, between the ozone-containing water having an ozone concentration of 0.1 mg / liter and the ozone-containing water having an ozone concentration of 0.01 mg / liter,
It can be seen that there is no significant difference in the bactericidal effect on bacteria in the urinal trap resident water. Therefore, it is thought that if ozone-containing water having an ozone concentration of 0.01 mg / liter is passed through the toilet, the adhesion of urine stones to the urinal can be suppressed.

(Example 5) 5 mm on urinal trap
Fix titania on the ball-shaped porous alumina of φ,
Further, a solid sample impregnated with an aqueous solution of silver nitrate was further placed on the solid sample.
By placing zero pieces and leaving them for one month, the urinal trap was checked for dirt. As a result, the urinal without the solid sample was discolored to a bright yellow color, but the urinal with the solid sample was hardly colored and stained, and the solid sample was used to prevent contamination of the urinal trap. It was confirmed that it had a great effect.

This effect is due to the fact that silver ions elute from the solid sample into the retained water, and the eluted silver ions act on bacteria adhering to the retained water or the urinal trap to be killed, thereby suppressing an increase in urease. Conceivable.

Example 6 In order to examine the bactericidal action of silver ions in staying water, silver nitrate was dissolved in ion-exchanged water so as to be 1 mg / liter in terms of silver weight, and further diluted with sterile ultrapure water. A test solution having a predetermined silver ion concentration was prepared. However, silver ion concentration of 1 mg / liter and 10
The test solution of mg / liter was prepared by directly dissolving in sterile ultrapure water. Escherichia coli (E. coli) was added to the above test solution at 2
× 10 ⁵ CFU / milliliter was added, and after standing for a predetermined time, potassium iodide was added to precipitate silver ions as silver iodide, which was removed from the test solution, and the survival rate of the bacteria was determined.

The results are shown in FIG. As a result, if the silver ion concentration is 1 mg / l or more, the survival rate of the bacterium can be reduced to 10% or less even with an action time of about 20 seconds, but if the silver ion concentration is about 1 μg / l, the bacterium cannot be acted for about 1 hour. Did not fall below 10%.

However, in the case of silver ions, the effect did not tend to decrease even if the action time was lengthened. Therefore, it can be said that it is more preferable to make it act slowly in the stagnant water or the like even when used in a toilet.

Example 7 In order to examine the bactericidal action of silver ions in the retained water, silver nitrate was converted to 100 mg / silver weight.
A test solution having a predetermined silver ion concentration was prepared by dissolving in liters of ion-exchanged water and further diluting with water from a low tank of a toilet. E. coli (Ec
oli) was charged at 2 × 10 ⁵ CFU / ml, left for a predetermined time, potassium iodide was added to precipitate silver ions as silver iodide, and the silver ions were removed from the test solution to determine the survival rate of the bacteria.

FIG. 24 shows the results. The working time was 2 hours. As a result, it was found that the survival rate of the bacterium can be reduced to 10% or less when the concentration is 1 μg / liter or more in terms of silver weight in the test solution. Therefore, even in the case of washing water actually used for a toilet, it can be said that if the action time is long, sterilization can be sufficiently performed and colored stains can be prevented.

(Eighth Embodiment) (1) A urinal installed in a company which is normally used in the daytime and hardly used at night is supplied with tap water or a toilet at 10:00 pm and 3:00 am at night. The water in the low tank was drained.

[0536] As a result, when the tap water was flushed, the trap portion of the toilet bowl in which the stagnant water was immersed at 8:00 am after one month was observed. . When the water in the toilet low tank is flushed, 1
After a lapse of months, a thin slime-like deposit was observed on the trap portion of the toilet bowl in which the stagnant water was immersed, and the deposit was colored in yellow.

Also, as a result of examining the number of bacteria in the retained water every week, as shown in Table 7, the number of bacteria in the retained water was 1 × 10 ⁴ CFU / ml at the maximum when tap water was supplied, 3 × 10 ⁴ CFU at maximum when running water inside
/ Milliliter.

(2) Next, as shown in FIG. 16, tap water or water in a low tank was introduced into a non-diaphragm type continuous electrolysis tank having flat electrodes, and iridium-platinum was formed into a titanium plate. Tap water or water in a toilet low tank is electrolyzed using a chlorine generation electrode coated with a system catalyst, and free chlorine-containing water generated by electrolysis is passed through a separate pipe from the urinal washing pipe. Urinals installed in the company, which are used normally during the day and rarely used at night, are flushed at 10 pm and 3 am at night.

[0539] As a result, when free chlorine-containing water having a free chlorine concentration of 1 mg / liter obtained by electrolyzing tap water was flowed, and when the free chlorine concentration obtained by electrolyzing water in the toilet low tank was 0.1 mL. In any case where 5 mg / liter of free chlorine-containing water was flowed, neither urine stone nor colored stain was observed on the trap portion of the toilet bowl where the retained water was immersed after one month.

Also, as a result of examining the number of bacteria in the staying water every week, as shown in Table 7, the number of bacteria in the staying water was not higher than the free chlorine concentration of 1 mg / liter obtained by electrolyzing tap water. When flowing chlorine-containing water, always 0 CFU / ml, when flowing free chlorine-containing water having a free chlorine concentration of 0.5 mg / liter obtained by electrolyzing water in a toilet low tank, a maximum of 2 × 10 CFU / ml, When flowing free chlorine-containing water having a free chlorine concentration of 0.1 mg / liter obtained by electrolyzing tap water, the maximum value was about 2 × 10 ³ CFU / ml.

[0541]

[Table 7]

(3) From the results of (1) and (2), when the number of bacteria in the stagnant water is 1 × 10 ⁴ CFU / milliliter or more, adhesion of urinary stones and coloring stains are likely to occur. Therefore, conversely, if the number of bacteria in the retained water can be maintained at less than 1 × 10 ⁴ CFU / milliliter, it is considered that the adhesion of urine stone and the coloring stain can be prevented.

Example 9 In order to examine the bactericidal action of free chlorine in the retained water, a predetermined number of Escherichia coli (E. coli) was added to water containing free chlorine of a predetermined concentration, and after 20 seconds, sodium thiosulfate was added. The free chlorine was then removed to determine the survival rate of the bacteria.

FIG. 25 shows the result. In FIG. 25, the horizontal axis indicates the bactericidal activity, that is, the reciprocal of the survival rate of the bacteria, and the vertical axis indicates the number of bacteria that can be sterilized per 1 mg of free chlorine. FIG.
5, the number of bacteria that can be sterilized per 1 mg of free chlorine is constant, regardless of the sterilizing power, and is 2.5 to 5 × 10 ¹⁰
It turned out to be individual. Therefore, bacteria 1 × 10 ⁴ CFU
/ The amount of free chlorine to sterilize milliliters is 0.2
It is considered that the number of bacteria in the stagnant water can be maintained at less than 1 × 10 ⁴ CFU / milliliter.

(Example 10) In the daytime, it is used normally.
The time-dependent changes in the bacterial count in urinals installed in the office, which are rarely used at night, were examined in the following cases, respectively.

First, when the number of bacteria is examined at 7:00 pm after work, the average is about 8 × 10 ² CFU / ml.

When left overnight, the number of bacteria is 1 × 10 ⁶ C on average.
Increase to about FU / milliliter.

On the other hand, at 10:00 pm and 3 am at night
If you try to run tap water from time to time, the next day at 8:00 am
It was maintained at about × 10 ³ CFU / ml. This is considered to be due to the fact that the tap water was supplied at 10:00 pm and 3:00 am at night to replace the stagnant water and to remove bacteria. Since the replacement ratio of the staying water in the actual toilet is about 99%, the same ratio (99%) of the bacteria in the staying water flows out of the toilet. However,
In this case, since no germicidal substance was brought into contact, even a small amount of the remaining bacteria proliferated, and foreign bacteria entered the stagnant water. At 8:00 am on the following day, 1 × 10 ³ CFU /
It is considered that the number of bacteria becomes about milliliter.

The number of bacteria in the retained water is always 0 CFU / milliliter when flowing free chlorine-containing water having a free chlorine concentration of 1 mg / liter obtained by electrolyzing tap water, and the water in the toilet low tank is electrolyzed. Free chlorine concentration obtained by
When flowing 5 mg / liter of free chlorine-containing water, a maximum of 1 × 10 CFU / ml is used. When flowing free water containing 0.1 mg / liter of free chlorine obtained by electrolysis of tap water, a maximum of 2 × 10 CFU / ml is used. It was about 10 ² CFU / milliliter.

When the free chlorine-containing water having a free chlorine concentration of 0.5 mg / L or 0.1 mg / L was flown, the number of bacteria did not become zero when the free chlorine-containing water was flowed at 3:00 am Is temporarily 0, but it is considered that the free chlorine concentration in the free chlorine-containing water became 0 before 8:00 am, and after that, foreign bacteria were mixed into the retained water or propagated.

Therefore, when flowing the water containing free chlorine at predetermined time intervals, after flowing the water containing free chlorine, before the concentration of free chlorine in the water containing free chlorine becomes zero, more preferably, zero than in the previous embodiment. It is thought that it is better to flow free chlorine-containing water again before the concentration becomes 0.2 μg / liter.

Example 11 A solution obtained by adding 20 ppm of ammoniacal nitrogen to tap water was electrolyzed to produce 2.8 ppm of bound chlorine. Pseudomonas aeruginosa (P. aeruginosa) was mixed into 25 ml of this solution at a bacterial concentration of 2 × 10 ⁷ CFU / ml, allowed to stand for a predetermined time, and then the chlorine content was collected with sodium thiosulfate. I asked. As shown in FIG. 27, under these conditions, the bacteria were almost completely eliminated by contact with the bound chlorine for 5 minutes.
