DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local cleaning device for discharging a predetermined amount of water or hot water as cleaning water based on a water discharge request to clean an anus, a vulva, and other skin surfaces.

[0002]

2. Description of the Related Art In recent years, toilet seats for local washing, which can wash a local part with washing water after excretion, have become widespread, and their comfort has become commonplace in toilets.

[0003] On the other hand, concerns about water pollution of tap water are increasing, and sales of mineral water are increasing year by year, and water purifiers for purifying tap water are also rapidly spreading. It is said that one household has some kind of water purifier.

At present, water purifiers that purify only drinking water are the mainstream, but there is an increasing need to wash the local area with clean water even for water for other uses, for example, a toilet seat for local cleaning. are doing.

In order to solve the above problem, recently, as disclosed in Japanese Utility Model Registration No. 2557082, a local cleaning toilet seat equipped with a device for purifying cleaning water has been proposed. It is for removing residual chlorine in tap water and providing skin-friendly water.

[0006]

However, there is a problem with the conventional device. In other words, in Japanese Utility Model Registration No. 2557082, a means for purifying by removing chlorine, foreign matter, turbidity and the like is disposed upstream of the hot water tank as a means for purifying cleaning water for local cleaning. An electrode is arranged on the downstream side of the water purification device to apply voltage and prevent the growth of bacteria in the washing water. However, this structure has the following problems. That is, the idea that it is necessary to provide a purifying device and a bacteriostatic device for the purpose of purifying the washing water for cleaning the local part, not only the structure becomes complicated as a household local cleaning device, but also It is unavoidable that the cost of the product is high and is not practical at all.

[0007] The local cleaning device proposed in the above publication is
It has the function of removing residual chlorine and turbid components in tap water, but it also has a function to prevent water from being passed through the supply of cleaning water or, in particular, the antifouling function of the nozzle, the function of cleaning local waste with cleaning water, and the prevention of skin diseases Was not possessed.

The present invention solves the above-mentioned conventional technology. In other words, it provides a local cleaning device that is inexpensive and has excellent practicality, has excellent antifouling properties in the water passage and the nozzle head, has a high filth cleaning effect, and can always clean a local portion with functional water that is gentle on the skin. Is what you do.

[0009]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is directed to a nozzle for extending and driving a predetermined amount of water or hot water based on a water discharge request, and providing the nozzle with water or hot water. A local washing device for washing an anus and a vulva, wherein an anion exchanger is detachable in the water passage and / or inside the nozzle. Is filled.

[0010] A nozzle is provided which is driven to extend and discharges a predetermined amount of water or hot water based on a water discharge request, and a water passage for supplying water or hot water to the nozzle is provided to clean the anus and vulva. In the local cleaning device for the above, the inside of the water passage and / or the inside of the nozzle is filled with an anion exchanger so as to be detachable, so that the inside of the water passage for washing water supply and / or Since the antifouling function of the nozzle is dramatically improved, the nozzle is extremely convenient and clean.

When the local cleaning device is used for a long period of time, dirt is generated in the water passage and particularly on the nozzle surface. this is,
At the time of local cleaning, the nozzle part comes close to the local part of the human body and ejects cleaning water, so after use, water droplets remain on the nozzle surface and dry, but at this time it is included in tap water Carbonate ions, and calcium and magnesium, which are also hardness components contained in tap water, combine
One cause is that poorly soluble substances such as calcium carbonate and magnesium carbonate are formed and adhere to the inside of the water passage and particularly to the nozzle surface.

[0012] Another cause of dirt adhering to the inside of the water passage or the nozzle surface is scale. This is a component that is difficult to completely remove because its main component is silica (SiO 2) and is usually present in water, but can be considerably removed by an anion exchanger, so it is dramatically improved. Antifouling function is enhanced.

That is, by providing an anion exchanger in the water passage, tap water that has passed through the anion exchanger is
Resulting in the following reactions: carbonate ions contained in tap water, sulfate ion, nitrate ion, water stain component (silica during adsorption ion: HSiO3 ^- to become) and anion components such as contained in the anion exchanger The water after the ion exchange with the anions to be formed is water from which carbonate ions and the like have been removed. For this reason, the above-mentioned calcium carbonate does not occur on the nozzle surface, and can significantly contribute to antifouling of the nozzle surface.

In a preferred aspect of the present invention, in the local cleaning device, the anion exchanger is a hydroxyl-type and / or halogen-type anion exchanger having a functional group terminal.

[0015] In the above-mentioned local cleaning device, since the anion exchanger is a hydroxyl-type and / or halogen-type anion exchanger having a functional group terminal, a user can use a functional cleansing water or a water-soluble one. This is extremely convenient because it is possible to generate cleaning water having excellent antifouling properties especially in the nozzle in the water path.

Since tap water contains anion components such as carbonate ion, sulfate ion, nitrate ion and silica ion, when tap water passes through a hydroxyl group type anion exchanger having a functional group terminal, As described above, an ion exchange reaction occurs. At this time, hydroxyl (OH) ions are released from the anion exchanger, so that the water after passing is alkaline water. In general, alkaline water is said to be excellent in the ability to clean organic substances such as proteins, and when used for applications such as the local cleaning device, it can enhance the cleaning effect of organic substances near the anus and in the local area of a woman. Good luck.

When tap water passes through a halogen-type anion exchanger having a functional group terminal, an ion exchange reaction occurs as described above, and halogen ions (chlorine ions, fluorine ions, iodine ions) having a strong oxidizing power are generated. ) Is released, the antibacterial property of the washing water is increased, and the propagation of various bacteria in the water passage is prevented, and in particular, the nozzle head is contaminated.

In a general local cleaning device, the clean water is heated in a hot water tank or, if there is no hot water tank, instantaneously heated by a heater, and then sent to a cleaning nozzle. Such a nozzle device is provided with a nozzle rod that reciprocates from a storage position of a casing to a washing position, and a nozzle head for ejecting washing water is provided at a tip of the nozzle rod. The thing is a general structure. However, at the time of washing, the nozzle head portion comes close to a local part of the human body and ejects washing water, so that it is easy to be exposed to sewage and dirt during washing. This makes it easy for bacteria that feed on filth to grow on the nozzle head, which contributes to significant contamination of the nozzle head.

From the above, by using a halogen type anion exchanger having a functional group terminal, dirt on a water flow path, particularly a nozzle head, can be remarkably suppressed, and the user is extremely comfortable and sanitary. In addition, the cleaning frequency is low and easy, which is very convenient.

[0020] In a preferred aspect of the present invention, in the local cleaning device, the anion exchanger has a diameter of 0.1 mm.
It is an anion exchange resin which is a sphere of 2 to 10 mm.

In the above-mentioned local cleaning device, since the anion exchanger is an anion exchange resin which is a sphere having a diameter of 0.2 to 10 mm, its handling is greatly facilitated, and its production cost or labor for replacement is greatly increased. Decreases,
Further, since the efficiency of the antifouling function is improved, the user can enjoy the benefits of the local cleaning device inexpensively and easily, which is extremely convenient.

That is, since the anion exchanger is detachable and thus exchangeable, even if the anion exchanger loses its ability, the anion exchanger is replaced and refilled again. Because it can be used, users can use functional water with improved detergency without breaks or functional water with antifouling function,
It is very convenient.

The washing water passes through the gap between the anion exchangers. When the washing water is a spherical anion exchange resin of a certain size, the gap is wide and the water flow resistance is very low. Therefore, since the flow rate of the washing water does not decrease, the user is extremely comfortable. Furthermore, spherical ion-exchange resins are generally commercially available, are relatively inexpensive, and have a high concentration of functional groups for the ion-exchange reaction. High fouling performance, very convenient.

Further, various types of anion exchangers are conceivable, but anion exchange resins having a diameter of 1 mm or less are generally widely used and relatively inexpensive and have good performance. This is desirable from the viewpoints of cost, water pressure loss and ion exchange performance. As a result, the user can purchase the local cleaning device at low cost, which is convenient. A sphere made larger by processing the ion exchange resin may be used. However, if the diameter exceeds 10 mm, the ion exchange reaction is not efficiently performed when water passes through the gap, which is not desirable. Conversely, when a small sphere having a diameter of less than 0.2 mm is used, it is extremely difficult to handle it, and the gap becomes small, resulting in a large pressure loss, which is not desirable.

The present invention includes a nozzle for extending and driving a predetermined amount of water or hot water based on a water discharge request, and a water passage for supplying the nozzle with water or hot water. In the local cleaning device for cleaning the genital area, a cation exchanger is filled in the water passage and / or the nozzle.

The nozzle includes a nozzle for extending and driving a predetermined amount of water or hot water based on a water discharge request, and a water passage for supplying water or hot water to the nozzle, and cleans the anus and vulva. In the local cleaning device for the above, since the cation exchanger is filled in the water passage and / or the nozzle, the convenience of the user of the local cleaning device is further improved.

That is, when tap water raw water supplied as washing water passes through the cation exchanger filled in the water passage and / or the nozzle, the sodium ion present in the cation exchanger Cations such as
Ion exchange with cations such as calcium ion and magnesium ion existing in tap water. As a result, the obtained washing water becomes so-called soft water having less hardness components such as calcium and magnesium. If the hardness component remains on the skin or mucous membranes, it becomes bulky or itchy, causes unpleasant emotions, and causes scratching of the skin, which is not preferable. Further, from the viewpoint of the local cleaning device, the hardness component is one of the causes of dirt in the cleaning nozzle and other scales (mainly calcium carbonate) in the piping, and is an unnecessary component.

From the above, by removing the hardness component in tap water with a cation exchanger, it is effective not only for preventing skin and mucous membranes in the human body but also for preventing contamination of a local cleaning device.

[0029] In a preferred aspect of the present invention, in the local cleaning device, the cation exchanger has a hydrogen-terminated functional group terminal.

In the above-mentioned local washing device, since the terminal of the functional group of the cation exchanger is of a hydrogen type, the user of the local washing device can use weakly acidic water, which is more convenient. improves.

That is, the cation exchanger having a functional group terminal of a hydrogen type can not only capture cations such as hardness components in tap water raw water as described above, but also generate hydrogen ions existing in the cation exchanger. Is released into the water,
The resulting wash water becomes weakly acidic. Because of this, it is possible to discharge weakly acidic water close to the pH of a healthy skin surface,
After washing the local part with alkaline water as described above, the skin can be treated with weakly acidic water, and the health of the skin surface can be maintained. If the skin surface remains alkaline, the function of protecting the skin from the outside will be weakened, causing skin diseases and the like.

Further, by making the washing water weakly acidic,
The generation of scale in the water passage or in the nozzle can be sufficiently and effectively suppressed. That is, dirt on the nozzle surface not only contributes to the hardness component existing in tap water, but also occurs as a result of bacteria adhering to the nozzle surface in the air or on the human body surface as described above. It is a factor. By generating the weakly acidic water, the bacterium is weak to an acidic pH and the propagation is suppressed, and as a result, the antifouling function is enhanced on the nozzle surface.

In a preferred aspect of the present invention, in the local cleaning device, the cation exchanger has a diameter of 0.1 mm.
It is a cation exchange resin that is a sphere of 2 to 10 mm.

In the above-mentioned local cleaning device, the cation exchanger is a cation exchange resin which is a sphere having a diameter of 0.2 to 10 mm, so that the pressure loss is low as in the case of the above-mentioned anion exchange resin. , High ion exchange efficiency,
In addition, it is easy to handle and commercially available, so it is inexpensive and very convenient.

[0035] In a preferred aspect of the present invention, in the local cleaning device, the anion exchanger and / or the cation exchanger may be arranged before and after the passage of the anion exchanger and / or the cation exchanger. A mesh-like membrane having pores of a size that does not pass through.

In the above-mentioned local cleaning device, a mesh having pores of a size not allowing the anion exchanger and / or cation exchanger to pass before and after the passage of the anion exchanger and / or cation exchanger. Since the ion exchanger takes the form filled in the mesh membrane even when the washing water passes by providing the membrane-like membrane, the ion exchanger does not leak out of the nozzle, which is convenient. .

[0037] In a preferred aspect of the present invention, in the local cleaning device, the different types of the ion exchangers are independently filled in the water passage and / or in the nozzle, and provided in the nozzle. Water that has passed through each ion exchanger is jetted from a plurality of jet holes at the multiple locations.

[0038] In the local cleaning device, different types of the ion exchangers are provided in the water passage and / or in the water passage.
Alternatively, the nozzles are independently filled inside the nozzles, and the water that has passed through the respective ion exchangers is jetted from a plurality of jet holes provided in the nozzle, so that the user can use alkaline water as the washing water. Since soft water having a neutral pH or soft water having a weak acidity can be used independently, it is extremely convenient as a local washing water. In addition, if the capacity of the ion exchange resin is lost due to long-term use, etc., it is necessary to replace the ion exchange resin. Can be exchanged for
Exchange is possible according to the life of each ion exchange resin, and there is no need to waste the ion exchange resin, which is convenient. Conversely, if each ion exchange resin is not independent, even if the capacity of the cation exchange resin remains, all must be replaced when the capacity of the anion exchange resin is lost, and This is extremely inconvenient in terms of effective utilization.

[0039] In a preferred aspect of the present invention, in the local cleaning device, the ion exchangers of different types are independently filled in the water passage and / or in the nozzle, and provided in the nozzle. A local cleaning device characterized in that water that has passed through each ion exchanger is switched and ejected from a group of ejection holes at predetermined locations.

As described above, from the ejection hole group at a predetermined location,
By switching and jetting the water that has passed through each ion exchanger, the user can switch between alkaline water and soft water with neutral pH or weakly acidic water for washing, or use neutral water with weak pH. It is very convenient as a local washing water because it is possible to selectively use soft water and weakly acidic water, alkaline water and water for suppressing the propagation of various bacteria. In addition, if the capacity of the ion exchange resin is lost due to long-term use, etc., it is necessary to replace the ion exchange resin. Can be exchanged according to the life of each ion exchange resin, and there is no need to waste the ion exchange resin, which is convenient. Conversely, if each ion exchange resin is not independent, even if the capacity of the cation exchange resin remains, all must be replaced when the capacity of the anion exchange resin is lost, and This is extremely inconvenient in terms of effective utilization.

[0041] In a preferred aspect of the present invention, in the local cleaning device, the nozzle has a nozzle lock, and is engaged with the nozzle engaging portion by the nozzle lock.

In the above-described local cleaning device, the nozzle is provided with a nozzle lock, and is engaged with the nozzle engaging portion by the nozzle lock, so that the nozzle can be attached to and detached from the local cleaning device. as a result,
The nozzle can be removed even if it has become dirty over a long period of use, which makes it very easy to clean the dirty nozzle or replace it with a new one, thus keeping the nozzle clean. The comfort is maintained, and the comfort is also improved.

As described above, the nozzle of the local cleaning device is inevitably stained as it is for a long period of time, but since the nozzle is detachable, cleaning and replacement of the nozzle can be performed. Maintenance work is greatly reduced, and it is very comfortable.

[0044] In a preferred aspect of the present invention, in the local cleaning device, the water passage is inside a hot water storage tank for storing and heating cleaning water.

In the local cleaning device, since the water passage is inside the hot water storage tank for storing and heating the washing water, the antifouling function in the water passage can be maintained extremely simply.

Since the hot water storage tank is configured to supply high-temperature washing water to the nozzle side through a pipe provided at the subsequent stage, the antifouling function can be maintained in a water passage below the hot water storage tank. It is convenient and desirable to arrange an anion exchanger and / or a cation exchanger in the hot water storage tank.

[0047]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In order to further clarify the configuration and operation of the present invention described above, a preferred embodiment of the present invention will be described below.

FIGS. 1 and 2 show an example of a nozzle in a local cleaning apparatus according to the present invention, which is the simplest case. FIG. 1 is a view of the nozzle section viewed from a cross section, and FIG. 2 is a view of the nozzle section viewed from above. The nozzle 1 is provided with an anal wash water flow path 2 and an anal wash water jet hole group 11, and further, a functional group terminal is provided with a halogen-type anion exchange resin 3, while a bidet wash water flow path 4 and a bidet wash water jet hole group 12, Further, similarly, a terminal of a functional group is provided with a halogen-type anion exchange resin 5.

During normal cleaning, the nozzle 1 is engaged with a nozzle engaging portion 21 provided in the main body of the local cleaning apparatus for engaging the nozzle. At this time, the nozzle 1 is engaged by the nozzle lock 22. The structure is such that washing water does not leak easily from the joint portion 21 and the O-ring 6 does not leak. On the other hand, when removing the nozzle, it can be easily removed by pulling the nozzle as shown in FIG. Further, when the effect of the anion exchanger has been weakened due to long-term use, the replacement lid 13 is opened by pulling the knob 14 as shown in FIG. Since the body 3 can be exchanged for a new one, the user can always enjoy the effect.

When the user cleans the anus, the tap water raw water 7 passes through the anal irrigation water flow path 2 and the terminal of the functional group is halogen-type while the nozzle 1 is engaged with the nozzle engaging portion 21. Pass through the anion exchange resin 3. At this time, anion components such as carbonate ions contained in the tap water raw water 7 and halogen ions contained in the anion exchange resin 3 are ion-exchanged, and the water after passing therethrough has an oxidizing power, and the propagation of various germs. It becomes water to suppress the function. The functional water is a group of anal wash water spouting holes 11
From the mouth and used for anal cleaning.

On the other hand, when the user performs bidet cleaning, the tap water raw water 8 passes through the bidet cleaning water flow path 4 and the terminal of the functional group is halogenated while the nozzle 1 is engaged with the nozzle engaging portion 21. Pass through the anion exchange resin 5 of the mold. At this time, similarly to the above, functional water for suppressing the propagation of various bacteria is discharged from the bidet wash water jet holes 12 and provided for bidet wash.

FIG. 3 is an example of a case where different types of ion exchangers are used using the nozzle shown in FIG. FIG.
Unlike the example of FIG. 3, the example of FIG. 3 shows a case in which the anus is washed with weakly acidic soft water and the bidet washing is performed with functional water that suppresses the growth of various bacteria. That is, when the user cleans the anus, the nozzle 1 is
In the state where the tap water raw water 7 is engaged with the
The terminal of the functional group passes through the cation exchange resin 15 in the hydrogen form. At this time, cation components such as calcium ions contained in the tap water raw water 7 are ion-exchanged with hydrogen ions contained in the cation exchange resin 15, and the water after passing is gentle on the skin and weak with bacteriostatic action. It becomes acidic and soft water and is used for anal irrigation.

Similarly, when the user performs bidet cleaning,
In a state where the nozzle 1 is engaged with the nozzle engaging portion 21, the tap water raw water 8 passes through the bidet washing water flow path 4, and passes through the anion exchange resin 16 whose functional group end is a halogen type. At this time, functional water for suppressing the growth of various bacteria is provided for bidet washing.

FIG. 4 is a further example of a nozzle in the local cleaning device of the present invention, and is a view of the nozzle portion viewed from a cross section. The nozzle 31 has an upper washing water channel 41, a lower washing water channel 42, an anion exchange resin 32 having a hydroxyl group-terminated functional group terminal, and a cation exchange resin 33 having a hydrogen-terminated functional group terminal.
In addition, an upstream valve 43 and a downstream valve 44 are provided. A water passage 45 is formed in the upstream valve 43, and a water passage 46 is formed in the downstream valve 44. Further, the upstream valve 43 and the downstream valve 44 rotate independently, and
Form various water passages.

The nozzle 31 is normally engaged with a nozzle engaging portion 51 provided in the main body of the local cleaning device for engaging the nozzle via a nozzle lock 52 as in FIGS.

In the case of this example, the user can select either or both of alkaline water or weakly acidic and soft water as the washing water when performing the anus and bidet washing. The user can freely select a switch (not shown) for discharging alkaline water or weakly acidic and soft water. FIG. 4 shows an example in which anal cleaning is performed using weakly acidic and soft water. That is, the tap water raw water 10 tries to enter the inside of the nozzle 31 in a state where the nozzle 31 is engaged with the nozzle engaging portion 51. However, since the downstream water passage is blocked by the upstream valve 43 as shown in FIG. On the other hand, since the water passage of the upstream valve 43 is open, the raw tap water 10 passes through the lower washing water flow path 42. Then, the tap water raw water 10 passes through the cation exchange resin 33 in which the terminal of the functional group is a hydrogen type. Here, cations such as calcium and magnesium contained in tap water raw water and the cation exchange resin cause an ion exchange reaction, whereby cations such as calcium are adsorbed by the ion exchange resin and hydrogen ions are released. Therefore, clean weakly acidic and soft water is obtained, and flows to the downstream valve side as shown in FIG. The obtained weakly acidic and soft water passes through the water passage 45 in the upstream valve 43 and the water passage 46 in the downstream valve 44, is discharged from the group of anal flushing water jet holes, and is provided as anal flushing water 61 for anal flushing. You. By rotating the upstream valve 43 so that the water passage 45 communicates with the hydroxyl group type anion exchange resin 32 at the end of the functional group, clean alkaline water is used as the anal cleaning water 61 and the anal cleaning water jet hole group. Can also be discharged from

FIG. 5 is an example of a case where different cleaning modes are performed using the nozzle shown in FIG. Unlike FIG. 4, the example of FIG. 5 shows an example in which bidet cleaning is performed with alkaline water. That is, the tap water raw water 10 tries to enter the inside of the nozzle 31 in a state where the nozzle 31 is engaged with the nozzle engaging portion 51. However, since the downstream water passage is closed by the upstream valve 43, the tap water does not pass through the lower washing water passage 42. On the other hand, since the water passage of the upstream valve 43 is open, the raw tap water 10 passes through the upper washing water flow path 41. Then, the tap water raw water 10 passes through the anion exchange resin 32 whose functional group ends are hydroxyl groups. Here, an anion such as a carbonate ion contained in the tap water raw water 10 and the anion exchange resin cause an ion exchange reaction, so that an anion such as a carbonate ion is adsorbed by the ion exchange resin and the hydroxyl ion is removed. Since the ions are released, clean alkaline water is obtained and flows to the downstream valve side as shown in FIG. The obtained alkaline water is supplied to the water passage 45 in the upstream valve 43 and the downstream valve 4.
After passing through the water passage 46 in the inside 4, the water is discharged from the group of bidet cleaning water jet holes, and is provided as bidet cleaning water 101 for bidet cleaning.
The upstream valve 43 is rotated so that the water passage 45 has a functional group terminal communicating with the hydrogen-type cation exchange resin 33 so that clean weakly acidic and soft water can be removed from the bidet washing water 1.
01 can be discharged from the bidet cleaning water ejection hole group.

In general, alkaline water is said to be excellent in the ability to clean organic substances such as proteins, and when used in applications such as the local cleaning device, it is necessary to enhance the cleaning effect of organic dirt near the anus and the local area of women. It is very convenient.

FIG. 6 is another example of the local cleaning apparatus according to the present invention, in which two types of cation exchange resins are used. That is, here, an example is shown in which a cation exchange resin having a hydrogen-terminated functional group and a cation exchange resin having a sodium-terminated functional group are filled. In a state where the nozzle 71 is engaged with the nozzle engaging portion 91, the tap water raw water 20 attempts to enter the inside of the nozzle 71. However, since the downstream water passage is closed by the upstream valve 83, the tap water does not pass through the lower washing water passage 81. On the other hand, since the water passage of the upstream valve 83 is open, the tap water raw water 20 passes through the upper washing water flow path 82. Then, the tap water raw water 20 passes through the cation exchange resin 72 whose functional group terminal is a hydrogen type. Here, cations such as calcium ions and magnesium contained in the raw tap water 20 and the cation exchange resin cause an ion exchange reaction, whereby cations of calcium ions are adsorbed by the ion exchange resin and hydrogen Since the ions are released, clean weakly acidic water is obtained and flows to the downstream valve side as shown in FIG. The obtained weakly acidic water passes through the water passage 85 in the upstream valve 83 and the water passage 86 in the downstream valve 84, is discharged from the bidet washing water ejection hole group, and is provided for bidet washing as the bidet washing water 102. .

In FIG. 6, raw water from tap water can be passed through a cation exchange resin 73 having a sodium end at the functional group by changing the water passage. In this case, since only sodium ions are released when cations such as calcium ions are adsorbed, the obtained water is soft water having a neutral pH. Therefore, for example, it is also possible to use the method in which the anus is first washed with soft water having a neutral pH and then washed with weakly acidic soft water to return the pH of the skin to a weakly acidic one.

FIG. 7 is also an example of a local cleaning apparatus according to the present invention, in which an anion exchange resin 111 having a functional group terminal of halogen type is filled in a hot water storage tank 112. Halogen-type anion exchange resin 11 with a functional group terminal
1 has a structure that does not leak from the hot water storage tank 112. The hot water storage tank 112 is provided with a tap water raw water pipe 113 and a cleaning water pipe 114 connected thereto, and further provided with a heater 115 for heating the cleaning water.

The tap water raw water 121 is a tap water raw water pipe 113.
Is stored in the hot water storage tank 112 through the heater 11
5 is heated to an appropriate temperature as local washing water. Halogen ions contained in the anion-exchange resin 111 having a functional group at the terminal end can sterilize even if the tap water raw water 121 contains any germs, thereby producing safe and clean water. Is done. The safe and clean washing water 122 flows toward the nozzle through the washing water pipe 114 and is provided for local washing.

FIG. 8 is a diagram showing an example of the ion exchange resin in the nozzle or the hot water storage tank in FIGS. The anion or cation exchange resin 130 is filled in the filling container 131. At this time, the filling container 131 is provided with a mesh membrane 132 having a hole having a size that does not allow the anion or cation exchange resin 130 to pass through. . Tap water raw water 133
Is passed through the anion or cation exchange resin 130 to become clean washing water 134 and is used for anus or bidet washing.
