Abstract

PROBLEM TO BE SOLVED: To effectively perform removal of bacilli adhering to the vicinity of the anus by discharging strong alkaline water with a specified pH range from a private part washing device after evacuation. SOLUTION: The water level in an alkaline water tank 6 and the water level in an acidic water tank 7 are detected by float valves, and when the water level of one of the tanks reaches less than a designated value, a solenoid valve 3 is opened to let city water flow in an electrolytic bath 5 to perform electrolysis. Thus, strong alkaline water with pH of 10-12 is generated, and the obtained strong alkaline water is stored in the tank 6. When a washing switch of a private part washing device is pressed by a user, it enters a preliminary washing mode, and a solenoid valve 2 is opened to let city water flow in a hot water tank 4, so that hot water in the hot water tank 4 is discharged from a nozzle 8, thereby washing away dirt adhering to the periphery of the anus after evacuation. After the end of preliminary washing, it enters alkaline water washing mode, so that strong alkaline water in the tank 6 is discharged from the nozzle 8 by the operation of a pump 9, thereby removing bacilli in the vicinity of the anus after preliminary washing.

Problems to be Solved by the Invention
No. 8, Japanese Patent Application Laid-Open No. 8-326124 refers to the effect of removing contaminants in alkaline water.
No mention is made of the correlation between the eradication effect. As a result of earnest studies, the inventors of the present application have found that strongly alkaline water having a pH of 10 or more is extremely effective in removing Escherichia coli attached near the anus after defecation. The present invention has been made based on the above findings, and it is an object of the present invention to provide a local washing apparatus capable of extremely effectively removing Escherichia coli attached to the vicinity of the anus after defecation.

[0004]

In order to solve the above-mentioned problems, the present invention provides a local cleaning apparatus which discharges strong alkaline water having a pH of 10 to 12. Strongly alkaline water having a pH of 10 or more has a strong detergency, and is extremely effective in removing Escherichia coli attached near the anus after defecation. If the pH is more than 12, irritation to the skin is increased, which is not preferable. Therefore, pH 10-12
By discharging the strong alkaline water, it is possible to extremely effectively remove Escherichia coli attached to the vicinity of the anus after defecation while suppressing irritation to the skin. It is effective to discharge warm water before discharging the strongly alkaline water to remove dirt attached to the vicinity of the anus in advance in order to enhance the washing and disinfecting effect of the strongly alkaline water. When the hypochlorous acid aqueous solution is acidic, the chlorine compound in the aqueous solution mainly becomes hypochlorous acid having a strong bactericidal activity. It is considered that strong alkaline water itself does not have bactericidal properties, so if the acidic water containing hypochlorous acid is discharged after discharging the strong alkaline water, it is possible to positively sterilize slightly remaining bacteria. . By discharging hot water, then discharging strongly alkaline water having a pH of 10 to 12, and then discharging acidic water containing hypochlorous acid, the area near the anus after defecation can be almost completely cleaned.

[0005] Strong alkaline water can be produced by electrolyzing tap water to which saline has been added, or by adding a drug to tap water. Acidic water containing hypochlorous acid is obtained by electrolyzing tap water.
Alternatively, it can be produced by adding a drug to tap water. If the soap used during bathing is attached near the anus, wash the area near the anus after defecation with tap water.
Calcium ions and magnesium ions, which are the hardness components in tap water, combine with the soap components to form metal soap, and the metal soap blocks pores near the anus and gaps between skin wrinkles and the like, impairing the cleaning effect, In addition, it may inhibit skin metabolism and cause inflammation and the like. Since soft water is unlikely to form a metallic soap, the use of soft water for cleaning the vicinity of the anus after defecation enhances the cleaning effect and suppresses the occurrence of inflammation and the like. Soft water can be produced by passing tap water through a cation exchange resin. When the cation exchange resin is a hydrogen-substituted cation exchange resin, acidic soft water that is easily compatible with weakly acidic human skin is generated, so that it is possible to prevent rough skin after washing.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The number of E. coli in the vicinity of the anus after defecation was measured. The measurement was performed according to the following procedure. After defecation, the area around the anus is cleaned by various methods. After washing, the area near the anus is rubbed with sterile saline and a sterile cotton swab to collect bacteria near the anus. The recovered bacteria are cultured in a selective medium for E. coli,
Count E. coli. FIG. 1 shows the measurement results. The following can be seen from FIG. By washing with strongly alkaline water having a pH of 10 or more, the number of remaining E. coli is drastically reduced to one-tenth or less as compared with washing with alkaline water having a pH of 9.5 or less. Since strong alkaline water itself is considered to have no bactericidal activity, the strong detergency of the strong alkaline water almost completely removes dirt remaining in pores and wrinkles in the skin near the anus and removes E. coli. As a result, it is considered that the number of remaining E. coli is drastically reduced. After washing with strongly alkaline water, washing with acidic water can reduce the number of remaining E. coli to zero. Acidic water contains hypochlorous acid because it is produced by electrolysis of tap water to which salt has been added. It is considered that the slightly remaining Escherichia coli is sterilized by the strong sterilizing power of hypochlorous acid, and the number of remaining Escherichia coli becomes zero.

Based on the above measurement results, the following is proposed as an effective method for cleaning the periphery of the anus after defecation. Washing is performed using strong alkaline water having a pH of 10 to 12. If the pH exceeds 12, irritation to the skin increases, so the pH is preferably 12 or less. After washing with strongly alkaline water having a pH of 10 to 12, washing is carried out with acidic water containing hypochlorous acid.
When the hypochlorous acid aqueous solution is acidic, the chlorine compound in the aqueous solution mainly becomes hypochlorous acid having a strong bactericidal activity. Therefore, it is desirable that the aqueous solution of hypochlorous acid is acidic. Before washing with strong alkaline water having a pH of 10 to 12, washing is performed with warm water. It is considered that removing dirt adhering to the vicinity of the anus in advance by washing with warm water is effective in sufficiently exerting the washing ability of strongly alkaline water. Washing is performed using warm water, then using strong alkaline water having a pH of 10 to 12, and then using acidic water containing hypochlorous acid. Preliminary washing with warm water to remove dirt beforehand, then washing out Escherichia coli with strongly alkaline water having a pH of 10 to 12 and then sterilizing slightly remaining Escherichia coli with acidic water containing hypochlorous acid will give an anal stool after defecation. The neighborhood is almost completely cleaned.

A local cleaning apparatus according to a first embodiment of the present invention will be described with reference to FIG. The constant pressure valve 1 is connected to a water supply pipe (not shown). An electromagnetic valve 2 and an electromagnetic valve 3 are arranged in parallel downstream of the constant pressure valve 1. A hot water tank 4 containing a heater is provided downstream of the solenoid valve 1. An electrolysis device 5 is provided downstream of the solenoid valve 2. Electrolysis device 5
Has an electrolysis tank, a saline solution tank for storing a saline solution, and a pump for pumping the saline solution in the saline solution tank and adding it to tap water flowing into the electrolytic bath. The electrolytic cell has an anode disposed in one of two flow paths separated by an ion-permeable membrane and a cathode disposed in the other, and an acidic water generated in the former and an alkaline water generated in the latter. May be separated from each other, and may be a diaphragm-type electrolytic cell configured to separate the cells, such as disclosed in International Publication WO96 / 03881 by the present applicant.
A flow path is formed between the anode and the cathode disposed facing each other without passing through the diaphragm, so that the acidic water generated near the anode and the alkaline water generated near the cathode are separately taken out. A configured non-diaphragm type electrolytic cell may be used. Downstream of the electrolytic device 5, an alkaline water tank 6 and an acidic water tank 7 are arranged in parallel. A nozzle 8 is provided downstream of the hot water tank 4, the alkaline water tank 6, and the acidic water tank 7. The nozzle 8 communicates directly with the hot water tank 4 and with the alkaline water tank 6 via a pump 9,
It communicates with the acidic water tank 7 via a pump 10. The alkaline water tank 6 and the acidic water tank 7 are provided with a float valve (not shown) for detecting a water level. The operations of the solenoid valves 2 and 3, the electrolysis device 5, the heater in the hot water tank, the pumps 9, 10 and the like are controlled by a control device (not shown).

[0009] The operation of the local cleaning apparatus according to the first embodiment having the above configuration will be described below. The float valve detects the water level in the alkaline water tank 6 and the water level in the acidic water tank 7. When one of the water levels falls below a predetermined value, the solenoid valve 3 opens, and the constant pressure valve 1 sets the flow rate to a predetermined flow rate. The adjusted tap water flows into the electrolysis device 5 and is electrolyzed after the saline solution is added. Even if the tap water to which no saline solution is added is electrolyzed, it is difficult to generate strong alkaline water having a pH of 10 or more due to lack of electrolyte, but by electrolyzing the tap water to which the saline solution is added, For example, as disclosed by the present applicant in JP-A-8-323307, strongly alkaline water having a pH of 10 to 12 can be produced. Strong alkaline water having a pH of 10 to 12 generated by the electrolysis of the saline solution flows into the alkaline water tank 6. The acidic water containing hypochlorous acid generated by the electrolysis of the saline solution flows into the acidic water tank 7. When the water level of the tank whose water level is lower than the predetermined value reaches the predetermined value, the operation of the electrolysis device 5 stops, and the solenoid valve 3 closes. Since the alkaline water and the acidic water are simultaneously generated by the electrolysis, the electrolyzed water overflows and is discarded from the tank having a sufficient water level before the start of the electrolysis.

When the user presses a cleaning switch (not shown) of the local cleaning device, a pre-cleaning mode is set, and the electromagnetic valve 2
Opens, and tap water flows into the hot water tank 4. The hot water in the hot water tank 4 is pushed out by the flowing tap water, is discharged from the nozzle 8, and cleans and removes dirt attached to the periphery of the anus after defecation. After the hot water cleaning has been continued for a predetermined time, the electromagnetic valve 2 closes, and the preliminary cleaning ends.

When the pre-cleaning is completed, the mode becomes a strong alkaline water cleaning mode, and the pump 9 operates. Strong alkaline water having a pH of 10 to 12 stored in an alkaline water tank 6 is pressure-fed to a nozzle 8 by a pump 9,
Discharge from. Due to the strong detergency of the strong alkaline water having a pH of 10 to 12, Escherichia coli adhering to the skin surface, pores, wrinkles and the like near the anus after the pre-washing is almost completely washed away. After the cleaning with the strong alkaline water has continued for a predetermined time, the operation of the pump 9 is stopped, and the cleaning with the strong alkaline water ends.

When the strong alkaline water cleaning is completed, the mode is set to the acidic water cleaning mode, and the pump 10 is operated. The acidic water containing hypochlorous acid stored in the acidic water tank 7 is pressure-fed to the nozzle 8 by the pump 10 and discharged from the nozzle 8. By sterilizing power of acidic water containing hypochlorous acid,
Escherichia coli remaining slightly in the vicinity of the anus is sterilized, and the vicinity of the anus is almost completely cleaned. After the washing with the acidic water containing hypochlorous acid has continued for a predetermined time, the operation of the pump 10 is stopped, and the washing with the acidic water ends. This completes a series of cleaning.

A local cleaning device according to a second embodiment of the present invention will be described with reference to FIG. A hot water tank 14 containing a heater is connected to a water supply pipe (not shown) via a constant pressure valve 11 and a solenoid valve 12. Electrolyzer 15 is hot water tank 14
And is connected to the hot water tank 14. The electrolysis device 15 has an electrolysis tank, a salt solution tank for storing a salt solution, and a pump for pumping the salt solution in the salt solution tank and adding it to tap water flowing into the electrolysis tank. The electrolytic cell has an anode disposed in one of two flow paths separated by an ion-permeable membrane and a cathode disposed in the other, and an acidic water generated in the former and an alkaline water generated in the latter. May be separated from each other, and the anode and the cathode may be arranged so as to face each other without a membrane, as disclosed in International Publication WO96 / 03881 by the present applicant. A non-diaphragm type electrolytic cell may be used in which a flow path is formed between the electrodes, and the acidic water generated near the anode and the alkaline water generated near the cathode are separately taken out. Downstream of the electrolyzer 15, three-way valves 19 and 20 are provided. The three-way valve 19 is connected to an alkaline water outlet (not shown) of the electrolysis device 15. The three-way valve 20 is connected to an acid water outlet (not shown) of the electrolysis device 15. 3
A nozzle 18a is provided downstream of the three-way valve 19,
It is connected to the. A nozzle 18 b is provided downstream of the three-way valve 20 and is connected to the three-way valve 20. Solenoid valve 12,
Heater in hot water tank 14, electrolyzer 15, three-way valve 1
The operations of 9 and 20 are controlled by a control device (not shown).

The operation of the local cleaning apparatus according to the second embodiment having the above configuration will be described below. When the user presses a cleaning switch (not shown) of the local cleaning device, a pre-cleaning mode is set, and the solenoid valve 12 is opened and 3
The one-way valve 19 communicates the nozzle 18a with the alkaline water outlet of the electrolyzer 15, and the three-way valve 20 communicates the nozzle 18b with the acidic water outlet of the electrolyzer 15. Tap water flows into the hot water tank 4. The hot water in the hot water tank 4 is pushed out by the inflowing tap water and the inactive electrolysis device 15 is not operated.
Through the three-way valve 19 and the three-way valve 20 and the nozzle 1
Discharge from 8a and 18b to wash and remove dirt adhering around the anus after defecation. Preliminary cleaning by warm water cleaning is continued for a predetermined time.

After the pre-cleaning has been continued for a predetermined time, the electrolysis device 15 is operated, and the three-way valve 20 cuts off the communication between the nozzle 18 b and the acidic water outlet of the electrolysis device 15. Electrolysis device 15
The tap water flowing into the tank is electrolyzed after the saline solution is added. Even if the tap water to which no saline solution is added is electrolyzed, it is difficult to generate strong alkaline water having a pH of 10 or more due to lack of electrolyte, but by electrolyzing the tap water to which the saline solution is added, Strong alkaline water having a pH of 10 to 12 can be produced. Strong alkaline water of pH 10 to 12 produced by electrolysis of saline solution
9 and is discharged from the nozzle 18a. pH 10-1
Due to the strong detergency of the strong alkaline water, Escherichia coli adhering to the surface of the skin, pores, wrinkles and the like near the anus after pre-washing is almost completely washed away. The acidic water containing hypochlorous acid generated by the electrolysis of the saline solution passes through the three-way valve 20 and is discarded through a pipe (not shown). Washing with strong alkaline water is continued for a predetermined time.

After the cleaning with the strong alkaline water has continued for a predetermined time, the three-way valve 20 connects the nozzle 18 b to the electrolysis device 15.
And the three-way valve 19 cuts off the communication between the nozzle 18a and the alkaline water outlet of the electrolytic device 15.
The acidic water containing hypochlorous acid generated by the electrolysis of the saline solution passes through the three-way valve 20 and is discharged from the nozzle 18b. Escherichia coli slightly remaining near the anus is sterilized by the sterilizing power of acidic water containing hypochlorous acid, and the vicinity of the anus is almost completely cleaned. The strongly alkaline water having a pH of 10 to 12 generated by the electrolysis of the saline solution is supplied to the three-way valve 19.
Through a pipe (not shown). After the cleaning with the acidic water containing strong hypochlorous acid continues for a predetermined time, the operation of the electrolysis device 15 is stopped, and the electromagnetic valve 12 is closed. This completes a series of cleaning.

Although the embodiments of the present invention have been described above, the present invention is not limited to the above embodiments. In the first and second embodiments, washing with hot water may be omitted, washing with acidic water may be omitted, and washing with warm water and washing with acidic water may be omitted. Instead of producing strongly alkaline water and acidic water containing hypochlorous acid by electrolysis of saline solution, a chemical such as NaOH is added to tap water to produce strongly alkaline water, and hydrochloric acid and hypochlorous acid are added to tap water. Acid water containing hypochlorous acid may be generated by adding sodium chlorate or the like. Instead of using tap water directly, tap water may be changed to soft water using a cation exchange resin or the like, and the soft water may be used for washing. If soap used at the time of bathing adheres to the vicinity of the anus, if the area near the anus after defecation is washed with tap water, calcium ions and magnesium ions, which are hardness components in the tap water, combine with the soap component to form metal soap. However, the metal soap may block pores near the anus, gaps between wrinkles in the skin, and the like, thereby impairing the cleaning effect, and inhibiting metabolism of the skin to cause inflammation. Since soft water is unlikely to form a metallic soap, the use of soft water for cleaning the vicinity of the anus after defecation enhances the cleaning effect and suppresses the occurrence of inflammation and the like. If the cation exchange resin is a hydrogen-substituted cation exchange resin, acidic soft water that is easily compatible with weakly acidic human skin is generated, so that it is possible to prevent rough skin after washing.

[0018]

In the local cleaning device according to the present invention,
Since strong alkaline water with a high detergency of pH 10 to 12 is discharged, Escherichia coli adhering to the vicinity of the anus after defecation can be extremely effectively eliminated. By discharging hot water before discharging the strongly alkaline water and removing in advance the dirt adhering to the vicinity of the anus, the disinfection effect of the strongly alkaline water can be enhanced. By discharging the acidic water containing hypochlorous acid after discharging the strong alkaline water, it is possible to sterilize bacteria slightly remaining near the anus. By discharging warm water, then discharging strongly alkaline water having a pH of 10 to 12, and then discharging acidic water containing hypochlorous acid, the area near the anus after defecation can be completely cleaned.
Since soft water is unlikely to form a metallic soap, the use of soft water for cleaning the vicinity of the anus after defecation enhances the cleaning effect and suppresses the occurrence of inflammation and the like.
