Abstract

<P>PROBLEM TO BE SOLVED: To clean a toilet bowl by using ozone water without increasing the ozone concentration of a narrow space such as a toilet. <P>SOLUTION: An ozone including bubble is turned into a micro-bubble generated by an ozone generator 10 and a micro-bubble generator 11 for generating the ozone including bubble turned into the micro-bubble, and is used as wash water of the toilet bowl 1. The micro-bubble is negatively electrified, and has a property of adsorbing bacteria and an organic substance in the water or on a surface coming into contact with the micro-bubble. Since the micro-bubble has the self-pressurizing effect, even when supplied as the low ozone concentration, ozone acts under a high pressured condition in action. Thus, since the micro-bubble adsorbs the bacteria and the organic substance in the water or on the surface being in contact with the micro-bubble by the electrification action of the micro-bubble including the ozone, the sterilizing, deodorizing, bleaching, stain decomposing and antifouling effect can be efficiently obtained by a small quantity of ozone including bubble. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a toilet cleaning device for cleaning a toilet using ozone water.

  As a toilet cleaning device for cleaning a toilet using conventional ozone water, the techniques of Patent Document 1 and Patent Document 2 can be cited.

  The technical idea described in Patent Document 1 is a cleaning water tank for storing cleaning water supplied to a toilet, an ozone generator that supplies ozone to the cleaning tank via an ozone supply path, and an ozone that supplies ozone-containing water to the toilet. A water supply device and a sensor for detecting the approach of a person to the toilet are provided, and a wash valve is interposed in the wash water supply path from the wash tank to the toilet. In addition to the wash valve, An ozone water supply path for supplying ozone-containing water to the toilet and a water supply valve for opening and closing the ozone water supply path are provided, and the ozone supply device is only while the sensor is in the human approach detection state. Control means for operating the water supply valve in conjunction with the operation of the proximity sensor so as to supply ozone-containing water from the washing water tank to the toilet.

  Therefore, when a person approaches the toilet, the ozone water supply device automatically supplies ozone-containing water separately from the cleaning water for automatic operation of the control means based on information from the sensor in the detection state. While supplying to the toilet bowl through the supply path, the supply is continued until the person finishes the toilet and leaves the toilet bowl. Therefore, ozone-containing water is supplied automatically and continuously in the stool, deodorizing and cleaning with water only, or chemicals are mixed into the water supplied for cleaning and simultaneously disappeared at the time of cleaning. Even if the amount of water supplied is reduced, ozone can act on urine and toilets to eliminate odors and sterilize and wash as compared with the case where the odor is reduced.

The technical idea described in Patent Document 2 relates to a toilet flushing apparatus in which an ozone water generating device is arranged inside or outside a washing tank so that ozone water flows at least a predetermined amount after toilet flushing. Specifically, by flushing the ozone water after washing the toilet bowl more than a predetermined amount, the toilet bowl surface after the filth is carried out can be sufficiently washed with the ozone water, and excellent deodorization and sterilization with the ozone contained in the ozone water The antifouling effect can be obtained, and the toilet can be kept clean and hygienic. In addition, as a means for supplying ozone water generated by the ozone water generator after toilet cleaning to the toilet bowl, an ozone water tank is provided in the cleaning tank, and the ozone water generated by the ozone water generator is supplied to the ozone water tank. I try to store it once. In particular, the toilet bowl cleaning water and the ozone water are separately stored, so that the toilet bowl surface can be sufficiently deodorized, sterilized, and antifouled even with a small amount of ozone water. . In this way, by flowing ozone water after washing the toilet bowl with at least washing water, effects such as deodorization, sterilization, and antifouling with ozone are obtained with less ozone water.
Japanese Examined Patent Publication No. 7-56151 JP 11-71797 A

  In Patent Document 1, ozone generated by an ozone generator is supplied to cleaning water in a cleaning tank, ozone is released from an ozone water supply device, and the ozone is dissolved in cleaning water to generate ozone water. In order to generate ozone water in this manner, a diffuser tube, a porous filter, a nozzle, and the like are usually used for the ozone water supply unit. Moreover, in patent document 2, the ozone production | generation apparatus comprised with an ozonizer (ozone generator) and an aspirator other than the said means is used. The generated ozone is sucked by the negative pressure generated by the cleaning water flowing through the aspirator, and is dissolved in the cleaning water to generate ozone water.

  Thus, when producing ozone water using the technical idea published in patent document 1 or patent document 2, since the ozone gas supplied to the washing water becomes large bubbles, the generation efficiency of ozone water is low.

  Therefore, it takes time to produce ozone water sufficient to flow in the entire toilet, and is unsuitable for continuously flowing wash water. In order to overcome this problem, there is a method of generating ozone gas having a high concentration from an ozone generator, generating ozone water having a predetermined concentration or more, and supplying the ozone water to cleaning water. However, according to this method, a large amount of ozone that has not been dissolved due to the disappearance of bubbles may be released into the atmosphere, and the surrounding ozone concentration may increase. Since high-concentration ozone is harmful to the body, it was not suitable for use in a narrow space such as a toilet.

  Accordingly, in order to solve these problems, an object of the present invention is to provide a toilet cleaning device for cleaning a toilet using ozone water that can be used without increasing the ozone concentration in a narrow space such as a toilet. .

  The toilet cleaning device according to claim 1 uses the microbubbled ozone-containing bubbles generated by an ozone generator and a microbubble generator that generates microbubbled ozone-containing bubbles as cleaning water for the toilet. is there.

  Research has revealed that ultrafine bubbles called microbubbles have different properties from conventional bubbles. For example, AIST (2004.1.8 press release) has succeeded in inactivating bacteria in water by using microbubbles containing ozone, and microbubbles have significantly enhanced the bactericidal effect of ozone. It is considered likely.

  Here, the ozone generator and the microbubble generator for generating microbubbles only need to have the ability to generate ozone-containing bubbles microbubbled in the cleaning water, preferably approximately 50 μm or less in diameter. Here, the diameter of approximately 50 μm or less is determined by the inventors based on various data, and is not a direct measurement, so even if there is a description of 50 μm in diameter, several percent of errors are involved. Estimated. Further, it has been confirmed by the inventors that the whitened turbid wash water containing the microbubbled ozone-containing bubbles has a bubble ratio of several percent or less due to the ozone-containing bubbles.

The toilet flushing apparatus according to claim 2 further includes a washing water tank that contains ozone-containing bubbles that are generated by the ozone generator and the fine bubble generator to form microbubbles.
Here, the washing water tank contains ozone-containing bubbles that are generated by an ozone generator and a fine bubble generator and converted into microbubbles. Absent. The auxiliary tank according to the present embodiment is also included.

  The toilet cleaning device according to claim 3, wherein the ozone-containing bubbles containing microbubbles generated by the ozone generator and the fine bubble generator are provided with a circulation channel for circulating the cleaning water in the cleaning water tank, A micro-bubble generator of a pump pulverization method is inserted into the circulation channel, and the ozone generator is connected to the micro-bubble generator, and the supplied ozone is refined by the micro-bubble generator. .

  Here, the pump pulverization type fine bubble generator only needs to have the ability to repeatedly subdivide the bubbles.

  According to a fourth aspect of the toilet cleaning device of the present invention, the ozone generator and the fine bubble generator operate when a human is detected by a human body detection sensor.

  The human body detection sensor is not limited to the detection of the body temperature of the human body directly by the infrared sensor, but the human body blocks a laser beam, light, electromagnetic wave or the like at a specific location, detects the movement of the human body, or reflects from the human body Detection means such as detecting waves can be used.

  The toilet bowl cleaning apparatus according to claim 5 is further configured such that the ozone generator and the fine bubble generator operate based on a series of operations of a flush toilet.

  Here, the term “acting based on the operation of the flush toilet” means something that operates based on opening / closing of a toilet door, opening / closing of a toilet lid and / or toilet seat, operation of a flush water drain lever, and the like.

  The toilet flushing device according to claim 6 operates when the flush toilet is operated when the ozone generator and the fine bubble generator are in the defecation state of the flush toilet.

  Here, the defecation state of the flush toilet means one that operates based on opening / closing of the toilet lid and / or toilet seat, operation of the flush water drain lever, and the like.

  The toilet flushing apparatus according to claim 7 is configured such that the operation of the flush toilet is performed before the ozone generator and the fine bubble generator are defecation of the flush toilet, and the ozone-containing bubbles containing microbubbles are allowed to flow as washing water. .

  Here, “before defecation of flush toilet” includes not only immediately before but also a timer operation at a predetermined time interval.

  In the toilet bowl cleaning device according to claim 8, the microbubbles are formed to have a diameter of approximately 50 μm or less.

  Ozone-containing bubbles with a diameter of 50 μm or less can be used in a state where fine bubbles are dispersed because ozone does not need to be completely dissolved in the wash water, and can be created in a shorter time than the generation of ozone water. it can. Therefore, it can be set as the wash water used for a short time which drains continuously to a toilet bowl. Here, the diameter of approximately 50 μm or less is estimated to involve several percent of errors as described above.

  The toilet cleaning device according to claim 1 uses the microbubbled ozone-containing bubbles generated by an ozone generator and a microbubble generator that generates microbubbled ozone-containing bubbles as cleaning water for the toilet. It is.

  Usually, microbubbles are negatively charged and have the property of adsorbing bacteria and organic substances on the surface in contact with water or microbubbles. In addition, since microbubbles have a self-pressurizing effect, even if the microbubbles are supplied as a low ozone concentration, ozone acts under conditions of high pressure during operation.

  Therefore, the microbubbles containing ozone adsorb bacteria and organic substances on the surface in contact with water or microbubbles, so that ozone sterilization, deodorization, bleaching, Dirt decomposition and antifouling effect can be obtained. Further, since the pressurized ozone and the adsorbed substance act due to the self-pressurizing action of the microbubbles, sterilization, deodorization, bleaching, dirt decomposition, and antifouling effects can be obtained even at a low ozone concentration. Moreover, the effect which removes the stain | pollution | contamination adhering to a toilet bowl by the ultrasonic wave which generate | occur | produces when a microbubble bounces is acquired. Furthermore, since the ultrafine ozone-containing bubbles that flow into the toilet bowl have a slow ascent rate in water, they exist in the water for a while and then dissolve to become ozone water. Therefore, the rate of decrease in ozone concentration is slower than normal ozone water, and the effect of ozone lasts longer. Furthermore, since ozone-containing bubbles continue to exist in the water for a while, a large amount of ozone is not released into the atmosphere at a time, and safety when used in a sealed space such as a toilet is improved.

  In addition to the effect of the first aspect, the toilet bowl cleaning device of the second aspect further includes a washing water tank that contains the ozone-containing bubbles generated by the ozone generator and the fine bubble generator to form microbubbles. It is.

  Therefore, since the microbubbled ozone-containing bubbles are difficult to disappear, the washing water tank that contains the microbubbled ozone-containing bubbles generates the microbubbled ozone-containing bubbles generated by the ozone generator and the fine bubble generator. By storing, it becomes possible to supply cleaning water without a time lag.

  In addition to the effect of the second aspect, the toilet bowl cleaning device of the third aspect circulates the cleaning water in the cleaning water tank by the microbubbled ozone-containing bubbles generated by the ozone generator and the fine bubble generator. A circulating flow path is provided, a pump pulverization type fine bubble generator is inserted into the circulation flow path, and an ozone generator is connected to the fine bubble generator so that the supplied ozone generates fine bubbles. It is refined by a vessel.

  Therefore, since the microbubbled ozone-containing bubbles are difficult to disappear, and the ozone-containing bubbles are repeatedly generated, the washing water tank for storing the microbubbled ozone-containing bubbles is provided with the ozone generator and the fine bubbles. By accommodating the ozone-containing bubbles generated by the generator and microbubbled, it becomes possible to supply cleaning water without a time lag.

  In addition to the effect described in any one of claims 1 to 3, the toilet generator of claim 4 is configured such that the ozone generator and the fine bubble generator detect a human by a human body detection sensor. It works.

  Therefore, since it can be operated only when it is determined by the human body detection sensor, useless amount of ozone is eliminated, and it can be used without increasing the ozone concentration in a narrow space such as a toilet.

  In addition to the effect described in any one of claims 1 to 3, the ozone generator and the fine bubble generator operate based on the operation of the flush toilet. is there.

  Therefore, the operation based on the operation of the flush toilet means the operation based on the opening / closing of the toilet door, the opening / closing of the toilet lid and / or the toilet seat, the operation of the flush water drain lever, etc. Therefore, since the ozone generator and the fine bubble generator can be operated, the responsiveness is good and the use amount of wasteful ozone is suppressed without increasing the ozone concentration in a narrow space such as a toilet. Can be used.

  In addition to the effect of claim 5, the toilet flushing device of claim 6 operates when the ozone generator and the fine bubble generator are in the defecation state of the flush toilet. Therefore, only for defecation, the ozone generator and the fine bubble generator can be operated, and the responsiveness is good and the use amount of wasteful ozone is suppressed to reduce the ozone concentration in a narrow space such as a toilet. Can be used without increasing.

  In addition to the effect of claim 6, the toilet cleaning device of claim 7 operates the ozone generator and the fine bubble generator before defecation of a flush toilet, and cleans the ozone-containing bubbles that are microbubbled. Since it is washed as water and pre-washed, the toilet bowl can be washed before and after defecation, and the toilet bowl can be made cleaner.

  In addition to the effect according to any one of claims 1 to 7, the toilet cleaning device according to claim 8 has a diameter of 50 μm or less, and therefore contains ozone having a diameter of 50 μm or less. The bubbles do not need to completely dissolve ozone in the washing water, can be used in a state where fine bubbles are dispersed, and can be created in a shorter time than the generation of ozone water. Therefore, it can be set as the wash water used for a short time which drains continuously to a toilet bowl.

  Next, a toilet bowl cleaning device according to an embodiment of the present invention will be described with reference to the drawings. In the second and subsequent embodiments, since the same symbols or the same reference numerals as those in the first embodiment indicate the same or corresponding components as those in the first embodiment, detailed description thereof is omitted. Only the differences will be described.

[Embodiment 1]
FIG. 1 is a structural layout diagram showing a toilet bowl cleaning apparatus according to Embodiment 1 of the present invention. Moreover, FIG. 2 is a flowchart which shows control of the toilet bowl washing | cleaning apparatus of Embodiment 1 of this invention.

  As shown in the figure, a toilet seat 2 and a toilet lid 3 are attached to the toilet bowl 1. The toilet 1 is connected to a wash water tank 5 through a wash water supply pipe 4. The washing water tank 5 is provided with an automatic washing valve 6, and the automatic washing valve 6 is opened by the operation of the operation lever 7, and washing water is supplied to the toilet 1. The supply of cleaning water is automatically stopped by the automatic cleaning valve 6. This mechanism is a known flush toilet configuration.

  The ozone generator 10 is an apparatus that generates ozone by any one of methods such as an ultraviolet ray method, a chemical generation method, and an electrolysis method in addition to the most popular silent discharge method. In the silent discharge method, an alternating high voltage is applied between two electrodes, air is passed between the electrodes, and oxygen is ozonized by the energy of ions in the discharge plasma.

  The fine bubble generator 11 is a bubble generating device having a bubble diameter of about 1 to 50 μm by vigorous stirring of water and ozone-containing air. As the fine bubble generator 11, a pump pulverization method, a turbulent flow method, a venturi method, a pore pressurization method, or a combination thereof can be used. In particular, when practicing the present invention, a pump pulverization method capable of generating a large amount of microbubbles in a short time is preferable. This pump pulverization method is a method of supplying air (ozone-containing air) with a cascade pump or the like and finely pulverizing bubbles with an impeller that rotates at high speed. The turbulent flow method is a method of shearing a gas in water into small bubbles by a hydrodynamic action. The venturi method is a method in which air is sucked from the pores by the negative pressure generated at the throttle portion provided in the water channel and is fined by the water flow. The pore pressurization method is a method of generating air bubbles in water by supplying compressed air from the pores.

  The ozone generator 10 sucks air from the outside according to an instruction from the controller 20, generates air having an increased ozone content, and supplies the air to the fine bubble generator 11 through the ozone supply pipe 13. In the fine bubble generator 11, washing water is taken from the input pipe 14 connected to the washing water tank 5, and the bubble diameter becomes a cloudy microbubble with a diameter of about 50 μm or less with a bubble diameter of about 1-50 μm by vigorous stirring of water and ozone-containing air The ozone-containing bubbles are supplied as cleaning water to the cleaning water supply pipe 4 via the output pipe 15. In the washing water supply pipe 4, microbubbled ozone-containing air bubbles having a diameter of 50 μm or less with a bubble diameter of about 1 to 50 μm supplied from the output pipe 15 are mixed and used for cleaning the toilet bowl of the toilet 1. .

  Here, it is desirable that the position of the input pipe 14 connected to the cleaning water tank 5 is always arranged below the water level where the cleaning water is supplied from the cleaning water tank 5 even when the cleaning water is discharged. . The output pipe 15 is connected to the cleaning water supply pipe 4 on the downstream side of the automatic cleaning valve 6 that is opened by the operation of the operation lever 7. As a result, the fine bubble generator 11 does not generate microbubbled ozone-containing bubbles having a diameter of 50 μm or less, which has a useless bubble diameter of about 1 to 50 μm.

  The human body detection sensor 21 measures the distance to the person using the reflection of the ultrasonic wave, and determines that the person is approaching the use position with respect to the toilet 1 if the distance is within a predetermined value. If the distance is greater than a predetermined value, it is determined that the person is far from the use position with respect to the toilet 1, and the output is input to the controller 20. The toilet lid 3 is provided with a toilet lid opening / closing switch 22 for detecting opening and closing. The output of the toilet lid opening / closing switch 22 is also input to the controller 20. The toilet seat 2 is provided with a pressure switch 23 for detecting the seating of a person.

  The controller 20 in the toilet bowl cleaning apparatus according to Embodiment 1 of the present invention performs control as shown in FIG.

  First, the output of the human body detection sensor 21 is observed in step S1, and when there is no detection output, the detection output of the human body detection sensor 21 is waited in step S1. If there is a detection output of the human body detection sensor 21 in step S1, it is determined in step S2 from the detection output whether the size of the detected object is larger than a predetermined value. However, in order to eliminate movements such as when people do not enter, the door is opened only for cleaning the door sill, or the movement of people in the hallway is detected from the toilet room, The process does not proceed to step S3 unless it is determined in step S2 that the size of the detected object is greater than or equal to the predetermined value from the detection output.

  When it is determined that the size of the detected object is equal to or larger than the predetermined size, the opening of the toilet lid 3 is determined by the toilet lid opening / closing switch 22 in step S3. If it is determined that the toilet lid opening / closing switch 22 is opened, the output of the pressure switch 23 of the toilet seat 2 is checked in step S4. When the pressure switch 23 is not operating, there is no possibility of defecation, so the process does not proceed to step S5. . However, when the pressure switch 23 is operated, it means that the user is sitting on the toilet seat 2, and the operation lever 7 is waited for in step S5. When the operation lever 7 is operated, the automatic cleaning valve 6 is opened and the supply of cleaning water to the toilet 1 is started. At the same time, the ozone generator 10 is operated in step S6, the fine bubble generator 11 is operated in step S7, and the washing water supply pipe 4 has a cloudy diameter of 50 μm or less with a bubble diameter of about 1 to 50 μm supplied from the output pipe 15. The ozone-containing bubbles made into microbubbles are mixed and supplied for cleaning in the toilet bowl of the toilet 1. This state continues for T seconds.

  Usually, this T second is set around the time from when the automatic cleaning valve 6 is opened until the water is stopped, and preferably, when set to a little longer, the ozone-containing bubbles that have been made into microbubbles are put into the toilet bowl of the toilet 1. Further, it can be formed like a coating film.

  If it is determined in step S8 that T seconds have elapsed, in step S9, the ozone generator 10 and the fine bubble generator 11 are stopped and set in a standby state.

  In addition, step S3, step S4, and step S5 operate | move based on a series of operation | movement of a flush toilet here.

  As described above, the toilet bowl cleaning device according to Embodiment 1 of the present invention is configured to flow cleaning water containing ozone-containing bubbles having a diameter of 50 μm or less into the toilet bowl of the toilet bowl 1. Therefore, the microbubbles containing ozone adsorb bacteria and organic substances on the surface in contact with the microbubbles in water, and ozone sterilization, deodorization, bleaching, and soil decomposition efficiently with a small amount of ozone-containing bubbles. Antifouling effect can be obtained. Further, since the pressurized ozone and the adsorbed substance act due to the self-pressurizing action of the microbubbles, sterilization, deodorization, bleaching, dirt decomposition, and antifouling effects can be obtained even at a low ozone concentration. And the effect which removes the dirt adhering in the toilet bowl of the toilet bowl 1 by the ultrasonic wave generated when the microbubbles bounce is also obtained. Furthermore, since the ultrafine ozone-containing bubbles that flow into the toilet bowl have a slow ascent rate in water, they exist in the water for a while and then dissolve to become ozone water. Therefore, the rate of decrease in ozone concentration is slower than normal ozone water, and the effect of ozone can be sustained for a long time. Further, since ozone-containing bubbles continue to exist in the water for a while, a large amount of ozone is not released into the atmosphere at a time, so that the safety when used in a sealed space such as a toilet is improved.

  In addition, ozone-containing bubbles having a diameter of 50 μm or less used in the present embodiment are generated by the fine bubble generator 11 and the ozone generator 10 and can be used in a state where the fine bubbles are dispersed. Therefore, since it is not necessary to completely dissolve ozone in the cleaning water, it can be generated in a shorter time than ozone water. Therefore, even when draining continuously to the toilet 1 as in the first embodiment, it is effective when cleaning water is required in a short time.

  In this way, by cleaning the toilet bowl 1 with cleaning water containing ozone-containing bubbles having a diameter of 50 μm or less, sufficient ozone sterilization, deodorization, bleaching, dirt decomposition, and antifouling effects can be obtained even when low-concentration ozone is used. It was confirmed by the inventors. In addition, since a large amount of ozone is not released from the cleaning water at once, the safety when used in a sealed space such as a toilet is improved. Further, since the production method can be made with low-concentration ozone, safety is similarly improved.

[Embodiment 2]
FIG. 3 is a structural layout showing a toilet bowl cleaning apparatus according to Embodiment 2 of the present invention.

  The difference between the first embodiment and the second embodiment is that the ozone generator 10 and the fine bubble generator 11 are continuously operated when the toilet 1 is used in the first embodiment, and ozone having a diameter of 50 μm or less during cleaning. Washing water containing contained bubbles is supplied to the toilet 1. However, in the second embodiment, by always supplying microbubbled ozone-containing bubbles having a bubble diameter of 50 μm or less to the cleaning water tank 5, it is retained as cloudy cleaning water and attempts to increase responsiveness during use. To do.

  That is, the toilet bowl cleaning device of Embodiment 2 takes in the wash water of the wash water tank 5 from the input pipe 14 and turns into cloudy microbubbles having a bubble diameter of about 1 to 50 μm by vigorous stirring of water and ozone-containing air. The cleaning water mixed with ozone-containing bubbles is returned from the output pipe 15 to the cleaning water tank 5. In this operation, by operating the ozone generator 10 and the fine bubble generator 11 at predetermined time intervals, the cleaning water tank 5 always retains cleaning water having ozone-containing bubbles formed into microbubbles having a bubble diameter of 50 μm or less. can do.

  In particular, the microbubbled ozone-containing bubbles exist in water for a while and then dissolve to become ozone water. Therefore, the rate of decrease in ozone concentration is slower than normal ozone water, and the effect of ozone lasts longer. Further, since ozone-containing bubbles continue to exist in water for a while, a large amount of ozone is not released into the atmosphere at one time.

  In this way, by cleaning the toilet 1 with the generated cleaning water containing ozone-containing bubbles having a diameter of 50 μm or less, sufficient ozone sterilization, deodorization, bleaching, soil decomposition, and antifouling effects can be achieved even with the use of low-concentration ozone. As a result, since a large amount of ozone is not released from the washing water at a time, the safety when used in a closed space such as a toilet is improved. Further, since the production method can be made with low-concentration ozone, safety is similarly improved. Moreover, since responsiveness is good, it is suitable also when the toilet bowl 1 is used continuously.

[Embodiment 3]
FIG. 4 is a structural layout diagram showing a toilet bowl cleaning apparatus according to Embodiment 3 of the present invention. FIG. 5 is a flowchart showing control of the toilet bowl cleaning apparatus according to Embodiment 3 of the present invention.

  The difference between the second embodiment and the third embodiment is that the second embodiment always supplies the washing water tank 5 with microbubbled ozone-containing bubbles having a bubble diameter of 50 μm or less, so that the washing water becomes cloudy. The third embodiment is intended to increase the responsiveness during use, but in the third embodiment, when ozone-containing bubbles that are microbubbled are repelled on the upper surface of the washing water, the ozone is diffused into the atmosphere. It is intended to prevent

  That is, the cleaning water tank 5 of the third embodiment has an auxiliary tank 5A having a volume of about 70 to 80% with the opening facing down. One end of the gas intake pipe 17 is connected to the upper part of the auxiliary tank 5A, and the other end of the gas intake pipe 17 is connected to the intake side of the ozone generator 10. In the auxiliary tank 5A, one end of the gas intake pipe 17 passes through, but is sealed between each other. One end of each of the input pipe 14 and the output pipe 15 serving as a circulation flow path passes through the auxiliary tank 5A, and these are also in a sealed state with the auxiliary tank 5A. The auxiliary tank 5A is joined to one surface so as not to move in the washing water tank 5.

  Other configurations are the same as those in the second embodiment.

  The toilet bowl cleaning apparatus of Embodiment 3 takes in the wash water of the wash water tank 5 from the input pipe 14, and contains the ozone that has become a cloudy microbubble having a bubble diameter of about 1 to 50 μm by vigorous stirring of water and ozone-containing air. The washing water mixed with bubbles is returned from the output pipe 15 to the washing water tank 5. As in the second embodiment, this operation is always performed by operating the ozone generator 10 and the fine bubble generator 11 at predetermined time intervals, so that the cleaning water tank 5 always contains ozone in the form of microbubbles having a bubble diameter of 50 μm or less. Wash water having bubbles can be retained.

  Precisely, from the position of the end of the output pipe 15, the auxiliary tank 5A in the cleaning water tank 5 holds cleaning water having ozone-containing bubbles that are microbubbled with a bubble diameter of 50 μm or less.

  At this time, since the ozone-containing bubbles that have been microbubbled have a slow ascent rate in water, they exist in the water for a while and then dissolve to become ozone water. Therefore, the rate of decrease in ozone concentration is slower than normal ozone water, and the effect of ozone lasts longer. Further, since ozone-containing bubbles continue to exist in water for a while, a large amount of ozone is not released into the atmosphere at one time. Even if some ozone is released from the surface of the cleaning water, the ozone stops at the upper part in the auxiliary tank 5A. The ozone in the auxiliary tank 5A is used as the introduction gas of the ozone generator 10 through the gas intake pipe 17 and is reused. Therefore, ozone having a high concentration can be used as the output of the ozone generator 10.

  That is, the auxiliary tank 5A used in the present embodiment functions as an ozone collection tank.

  When cleaning water is supplied into the toilet 1 while the ozone generator 10 and the fine bubble generator 11 are in operation, or when the gas in the auxiliary tank 5A decreases, the cleaning water tank is larger than the cross-sectional area X of the auxiliary tank 5A. 5 and the auxiliary tank 5A are formed with a sectional area Y of about 8 to 2, the level of the cleaning water at the interval between the cleaning water tank 5 and the auxiliary tank 5A is lowered, and the cleaning water tank 5 Air will be replenished with respect to 5 A of auxiliary tanks from the space | interval side with 5 A of auxiliary tanks. Specifically, air is supplied from the lower left of the auxiliary tank 5A.

  Conversely, when the toilet bowl cleaning device of the present embodiment is not used for 3 to 4 days, the gas space above the auxiliary tank 5A increases the volume. If it becomes maximum, gas is discharged from the lower left of the auxiliary tank 5A.

  In addition, there is nothing different from the first embodiment and the second embodiment for cleaning the toilet bowl.

  The controller 20 in the third embodiment is controlled as shown in FIG.

  First, in step S11, it is determined whether or not it is time to drive the ozone generator 10 and the fine bubble generator 11 at predetermined time intervals. When the specified time t is reached after seeing the passage of time of the set timing t, the ozone generator 10 is operated in step S16, and the fine bubble generator 11 is operated in step S17. Thus, the cleaning water tank 5 circulates in the auxiliary tank 5 </ b> A while generating the microbubbled ozone-containing bubbles having a bubble diameter of 50 μm or less supplied from the output pipe 15. The gas such as ozone in the auxiliary tank 5A is used as an introduction gas of the ozone generator 10 through the gas intake pipe 17, and ozone is reused. Therefore, ozone having a high concentration is output from the ozone generator 10. It can be.

  Usually, the driving of the ozone generator 10 and the fine bubble generator 11 is continued for M minutes to maintain the microbubbled ozone-containing bubbles in the auxiliary tank 5A at a predetermined concentration, and the passage of M minutes is determined in step S18. In step S19, the ozone generator 10 and the fine bubble generator 11 are stopped, and in step S20, the timer for driving the ozone generator 10 and the fine bubble generator 11 is reset (t = 0), and Then, the timer for measuring the time M for maintaining the microbubbled ozone-containing bubbles in the auxiliary tank 5A at a predetermined concentration is reset (M = 0), and the process returns to step S11 in the standby state.

  Even when it is determined in step S11 that it is not time to drive the ozone generator 10 and the fine bubble generator 11, if the operation lever 7 is operated in step S12, the automatic cleaning valve 6 is opened and the toilet 1 is supplied with the cleaning water. Since the supply is started, the ozone generator 10 and the fine bubble generator 11 in steps S16 to S20 are also driven at this time, and the ozone-containing bubbles formed into microbubbles in the auxiliary tank 5A are maintained at a predetermined concentration. Get into operation.

  In step S11, when it is determined that it is not time to drive the ozone generator 10 and the fine bubble generator 11, and it is determined that the operation lever 7 is not operated in step S12, the human body detection sensor 21 is set in step S13. When the output is viewed, when there is no detection output, the process returns to step S11. If the detection output of the human body detection sensor 21 is present in step S13, the toilet lid opening / closing switch 22 determines whether the toilet lid 3 is opened in step S14. When it is determined that the toilet lid opening / closing switch 22 is opened, the output of the pressure switch 23 of the toilet seat 2 is checked in step S15. When the pressure switch 23 is not operating, there is no possibility of defecation, and the process returns to step S11. However, when the pressure switch 23 is operated, it means that the user is sitting on the toilet seat 2, so that the ozone generator 10 is operated in step S16, the fine bubble generator 11 is operated in step S17, and the inside of the auxiliary tank 5A of the washing water tank 5 is operated. Circulates by mixing microbubbled ozone-containing bubbles having a bubble diameter of 50 μm or less supplied from the output tube 15. The gas such as ozone in the auxiliary tank 5A is used as an introduction gas of the ozone generator 10 through the gas intake pipe 17, and ozone is reused. Therefore, ozone having a high concentration is output from the ozone generator 10. It can be. This state continues for M minutes, and in the meantime, in the auxiliary tank 5A of the washing water tank 5, the microbubble-containing ozone-containing bubbles are mixed and circulated to increase the concentration.

  When the passage of M minutes is determined in step S18, the ozone generator 10 and the fine bubble generator 11 are stopped in step S19, and a timer for driving the ozone generator 10 and the fine bubble generator 11 is set in step S20. Reset (t = 0), and reset (M = 0) a timer that measures the time M for maintaining the microbubbled ozone-containing bubbles in the auxiliary tank 5A at a predetermined concentration. Return to.

  In addition, step S12, step S14, and step S15 operate | move based on a series of operation | movement of a flush toilet here.

  In the first to third embodiments, the human body detection sensor 21 is provided on the attachment members of the toilet seat 2 and the toilet lid 3, but the present invention is limited to this configuration. is not.

  FIG. 6 is an explanatory diagram showing a positional relationship between a human body detection sensor and a sensor that detects opening and closing of a door that can be placed in the toilet bowl cleaning device according to each embodiment of the present invention.

  As the human body detection sensor 21, a so-called proximity switch can be used, and detection means such as detection of a human body temperature directly by an infrared sensor or detection of a reflected wave from the human body can be used.

  The human body is positioned between the transmitters 32A and 33A for the beams of laser, light, electromagnetic waves, etc. and the receivers 32B and 33B, and the position of the person is detected by blocking the beams of laser, light, electromagnetic waves, etc. it can. The transmitter 32A and the receiver 32B in FIG. 6 detect a person who has entered the toilet 40, and the transmitter 33A and the receiver 33B detect a person seated on the toilet seat 2. Moreover, the opening / closing of the door 41 of the toilet 40 can be detected by the magnet switch 31.

  The human body detection sensor 21 in the case of carrying out the present invention is not limited to the detection of the body temperature of the human body directly by the infrared sensor, but the human body blocks a beam of laser, light, electromagnetic waves, etc. at a specific location, Alternatively, detection means such as Doppler detection using a microwave or the like or detection of a reflected wave from a human body can be used.

  As described above, the toilet bowl cleaning device of the above-described embodiment uses the ozone generator 10 and the microbubbled ozone-containing bubbles generated by the microbubble generator 11 that generates the microbubbled ozone-containing bubbles. It is used as washing water.

  In general, microbubbles are negatively charged and have the property of adsorbing bacteria and organic substances on the surface in contact with water or microbubbles. In addition, since microbubbles have a self-pressurizing effect, even if the microbubbles are supplied as a low ozone concentration, ozone acts under conditions of high pressure during operation.

  Therefore, the microbubbles containing ozone adsorb bacteria and organic substances on the surface in contact with water or microbubbles, so that ozone sterilization, deodorization, bleaching, Dirt decomposition and antifouling effect can be obtained. Further, since the pressurized ozone and the adsorbed substance act due to the self-pressurizing action of the microbubbles, sterilization, deodorization, bleaching, dirt decomposition, and antifouling effects can be obtained even at a low ozone concentration.

  Moreover, the effect which removes the stain | pollution | contamination adhering to a toilet bowl with the ultrasonic wave which generate | occur | produces when a microbubble bounces is also acquired. Furthermore, since the ultrafine ozone-containing bubbles that flow into the toilet bowl have a slow ascent rate in water, they exist in the water for a while and then dissolve to become ozone water. Therefore, the rate of decrease in ozone concentration is slower than normal ozone water, and the effect of ozone lasts longer. Furthermore, since ozone-containing bubbles continue to exist in the water for a while, a large amount of ozone is not released into the atmosphere at a time, and safety when used in a sealed space such as a toilet is improved. Even if ozone is released into the atmosphere, ozone molecules return to oxygen in a short time because the binding force is unstable. Therefore, it is an environmentally friendly technology because it does not cause secondary air pollution in the toilet 40. For example, the interior of the toilet 40 can maintain a concentration of the working environment standard value of 0.1 ppm or less when inhaling continuously for 8 hours.

  Further, in the case where the cleaning water tank 5 that contains the ozone-containing bubbles generated by the ozone generator 10 and the fine bubble generator 11 is accommodated, the ozone-containing bubbles that are microbubbled in the cleaning water tank 5 disappear. Since it is difficult, the washing water tank 5 containing the microbubble-containing ozone-containing bubbles contains the ozone-containing bubbles generated by the ozone generator 10 and the fine bubble generator 11 so as to have no time lag. Can be supplied.

  The inventors have confirmed that the whitened turbid wash water containing the microbubbled ozone-containing bubbles has a bubble rate of several percent or less due to the ozone-containing bubbles.

  In particular, as in the second and third embodiments, the microbubbled ozone-containing bubbles generated by the ozone generator 10 and the fine bubble generator 11 circulate the cleaning water in the cleaning water tank 5. A circulation flow path composed of an input pipe 14 and an output pipe 15 is provided, a pump pulverization type fine bubble generator 11 is inserted into the circulation flow path, and an ozone generator 10 is connected to the fine bubble generator 11. Then, the supplied ozone is refined by the fine bubble generator 11. Accordingly, the ozone-containing bubbles that are microbubbled are difficult to disappear, and furthermore, the ozone-containing bubbles are repeatedly generated. Therefore, the washing water tank 5 that contains the microbubbled ozone-containing bubbles is provided with the ozone generator 10 and the fine bubbles. By accommodating the ozone-containing bubbles generated by the generator 11 and made into microbubbles, it becomes possible to supply cleaning water without a time lag.

  In the toilet cleaning device of the second and third embodiments, the ozone generator 10 and the fine bubble generator 11 are operated based on a series of defecation operations in a flush toilet. Here, the operation based on the operation of the flush toilet means one that operates based on the opening / closing of the door 41 of the toilet 40, the opening / closing of the toilet lid 3 and / or the toilet seat 2, the operation of the drain lever 7 of the washing water, and the like. Therefore, the ozone generator 10 and the fine bubble generator 11 can be operated regardless of the presence or absence of defecation, the responsiveness is good, and the amount of useless ozone is suppressed, so that the toilet 40 or the like can be used in a narrow space. Can be used without increasing the ozone concentration.

  In particular, since the operation of the flush toilet is performed when the ozone generator 10 and the fine bubble generator 11 are in the defecation state of the flush toilet, the ozone generator 10 and the fine bubble generator 11 are operated only for defecation. Therefore, it is possible to use without increasing the ozone concentration in a narrow space such as the toilet 40 by suppressing the use amount of useless ozone.

  Although not described in the first to third embodiments, the ozone generator 10 and the fine bubble generator 11 are operated before defecation in the flush toilet, and the ozone-containing bubbles that are microbubbled are allowed to flow as washing water. If pre-washing is performed, the inside of the toilet bowl can be washed before and after defecation, and the toilet bowl can be cleaned.

  In the above embodiment, since microbubbles are formed with a diameter of 50 μm or less, ozone-containing bubbles having a diameter of 50 μm or less do not need to completely dissolve ozone in the washing water, and fine bubbles are dispersed. It can be used in a short time compared to the generation of ozone water. Therefore, it can be set as the wash water used for a short time which drains continuously to a toilet bowl.

  The configuration of the toilet bowl cleaning device according to each embodiment of the present invention can also be used around water such as a kitchen and a washroom.
