[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hand washing apparatus.

[0002]

2. Description of the Related Art Hand washing apparatuses for disinfecting and washing hands using hypochlorous acid-containing acidic water are used in catering centers, hospitals and the like. When hands are washed using a hand washing device, hypochlorous acid-containing acidic water is discharged from the hand washing device, and dirt attached to hands is removed using the water and soap, and bacteria are removed.

[0003]

The conventional hand washing device is

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. The hand washing device according to the present embodiment includes an electromagnetic valve 1,
A soft water generator 2 and a hypochlorous acid generator 3 are provided. Solenoid valve 1, Soft water generator 2, Hypochlorous acid generator 3
Are connected in series from the upstream to the downstream in the order of the electromagnetic valve 1, the soft water generator 2, and the hypochlorous acid generator 3. The solenoid valve 1 is connected to a water supply pipe (not shown).
A faucet (not shown) is connected to the hypochlorous acid generator 3. The soft water generator 2 has a hydrogen-substituted cation exchange resin. The hypochlorous acid generator 3 has an electrolytic layer (not shown), a saline solution tank, and a pump for adding the saline solution stored in the saline solution tank to the soft water flowing into the electrolytic layer. The electrolytic cell may be an electrolytic cell for ionic water generation configured to separately discharge acidic water generated in the vicinity of the anode and alkaline water generated in the vicinity of the cathode, or simply electrolyze a saline solution. Electrolytic cell may be used. Optical sensor 4 for detecting the presence of a human hand in proximity to a faucet (not shown)
Are arranged. The operation of the solenoid valve 1 and the operation of the hypochlorous acid generator 3 are controlled by the controller 5.

In the hand washing apparatus according to the present embodiment having the above configuration, when the user puts his / her hand in front of the faucet, the presence of the hand is detected by the optical sensor 4 and a detection signal is sent to the control device 5. . The control device 5 opens the solenoid valve 1 and activates the hypochlorous acid generator 3. Tap water flows into the soft water generator 2 through the solenoid valve 1. Hardness components such as calcium ion and magnesium ion in tap water
The hydrogen ion is replaced by hydrogen ions by the hydrogen-substituted cation exchange resin of the soft water generator 2, and the tap water becomes acidic soft water. The acidic soft water flowing out of the soft water generator 2 flows into the hypochlorous acid generator 3. A saline solution is added to the acidic soft water flowing into the hypochlorous acid generator 3 from a saline tank of the hypochlorous acid generator 3. The acidic soft water to which the saline solution has been added flows into the electrolytic layer of the hypochlorous acid generator 3 and is electrolyzed. Hypochlorous acid-containing acidic soft water is generated near the anode, and alkaline soft water is generated near the cathode. The hypochlorous acid-containing acidic soft water generated near the anode and the alkaline soft water generated near the cathode are mixed and neutralized to form hypochlorous acid-containing acidic soft water having a pH before electrolysis. If the electrolytic cell is an electrolytic cell for generating ionic water, the separately discharged acidic water and alkaline water are mixed and neutralized. Since an acidic hypochlorous acid aqueous solution mainly contains hypochlorous acid (HClO) having a strong bactericidal activity, the solution has a strong bactericidal activity. The germicidal hypochlorous acid-containing acid soft water flowing out of the hypochlorous acid generator 3 is:
It is discharged from a faucet (not shown), and is used for disinfection and cleaning of hands. When hands are disinfected and washed using hypochlorous acid-containing acidic soft water and soap, the soft water does not easily produce metal soap. Is suppressed. After discharging the hypochlorous acid-containing acidic soft water for a predetermined time, the control device 5 stops the operation of the hypochlorous acid generating device 3 and discharges only the acidic soft water generated by the soft water generating device 2 from the faucet. . The user rinses his / her hands with the acidic soft water to complete the hand washing.

Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. A device for adding sodium hydrogen carbonate may be added to the soft water generator 2. By adding the moisturizing properties of sodium bicarbonate to the soft water, the drying and roughening of the skin is more effectively suppressed. The cation exchange resin of the soft water generator 2 may be replaced with a cation exchange resin of a sodium substitution type. In this case, the neutral soft water generated by the soft water generator 2 is passed through the hypochlorous acid generator 3 having an electrolytic tank for generating ionic water, and is generated by the hypochlorous acid generator 3. Only the acid soft water containing hypochlorous acid is discharged from the faucet. The hypochlorous acid generator 3 may be a device that adds a chemical such as sodium hypochlorite to soft water and adds hypochlorous acid to the soft water.
In this case, it is desirable to generate an acidic soft water using a soft water generator having a hydrogen-substituted cation exchange resin. The alkaline soft water generated in the hypochlorous acid generator 3 having the electrolytic cell for generating ionized water is discharged from the faucet, and the hypochlorous acid-containing acidic soft water generated in the hypochlorous acid generator 3 is then discharged from the faucet. The hypochlorous acid-containing acidic soft water generated by the hypochlorous acid generating device 3 is mixed with the hypochlorous acid-containing acidic soft water and the alkaline soft water, and the hypochlorous acid-containing acidic soft water is discharged from the faucet. The operation of the device 3 may be stopped to discharge neutral soft water or acidic soft water. Alkaline water has a function of dissolving and removing fats, proteins, and the like. Therefore, by washing hands with alkaline soft water, dirt attached to hands can be removed without using soap.
As a result, the production of metal soap can be completely prevented, and the drying and roughening of the skin can be more effectively suppressed. The hands from which the stains have been removed are sterilized with hypochlorous acid-containing acidic soft water, and then rinsed with acidic soft water or neutral soft water to complete the hand washing. A faucet that discharges soft water from the soft water generator 2 without passing through the hypochlorous acid generator 3 may be provided separately from the faucet that discharges water flowing out of the hypochlorous acid generator 3. Hypochlorous acid generator 3 from soft water generator 2
If a faucet that discharges soft water is provided separately without passing through, the soft water that comes out of the faucet can be used as drinking water. Instead of the saline solution tank, a tank for storing an aqueous solution containing chlorine ions other than saline, such as an aqueous solution of hydrochloric acid or an aqueous solution of sodium hypochlorite, may be provided in the hypochlorous acid generator 3.

[0009]

In the hand washing device according to the present invention, the soft water generating device having a cation exchange resin removes the hardness component from tap water to generate soft water, and the hypochlorous acid generating device replaces the soft water with the soft water. Chlorous acid is added. An acidic pH is imparted to the soft water by a soft water generating device or a hypochlorous acid generating device, and the hypochlorous acid-containing acidic soft water is discharged from the hand washing device and provided for use. When hands are disinfected and washed using hypochlorous acid-containing acid soft water and soap,
Since soft water is unlikely to produce metal soap, pores are not blocked by foreign substances, so that metabolism of the skin is not inhibited, and drying and rusting of the skin is suppressed. By adding the moisturizing properties of sodium bicarbonate to the soft water, the drying and roughening of the skin is more effectively suppressed.
