  Hereinafter, the best mode for carrying out the present invention will be described with reference to FIGS. In the electrolyzed water supply system shown in FIG. 1, 1 is a water supply pipe to which tap water is supplied, 2 is supplied with tap water (clean water) from the water supply pipe 1 and is chlorinated such as sodium chloride (salt) or potassium chloride. It is an electrolysis accelerator tank in which an electrolysis accelerator (electrolysis accelerator) containing physical ions is replenished as needed, and the electrolysis accelerator tank 2 stores an aqueous solution of the electrolysis accelerator.

  3 is an electrolyzed water generating device in which tap water is supplied from the water supply pipe 1 and an aqueous solution of the electrolysis promoter is supplied from the electrolysis promoter tank 2, and this electrolyzed water generating device 3 has an electrode built therein for electrolysis. By performing, electrolyzed water containing hypochlorous acid or the like having a relatively high concentration (for example, an effective chlorine concentration of 6000 mg / L) is generated.

  Reference numeral 4 denotes an air purifier (first purification device) that uses electrolyzed water containing hypochlorous acid generated by the electrolyzed water generating device 3. The electrolyzer 5 stores the electrolyzed water and the electrolyzer of the electrolyzer 5. The sterilization element 6 to which water is dripped, the duct 7 for supplying room air to the sterilization element 6 and the blower fan 8 are configured. The room air is supplied to the sterilization element 6 in which relatively high concentration electrolyzed water is moistened. It passes through and cleans the room air while sterilizing it.

  Reference numeral 9 denotes a first electrolyzed water dilution device to which tap water is supplied from the water supply pipe 1 and electrolyzed water is supplied from the electrolyzed water generating device 3. As will be described later, the electrolyzed water dilution device 9 mixes high-concentration electrolyzed water with tap water to obtain electrolyzed water with medium concentration (for example, effective chlorine concentration of 10 mg / L or more), and dilutes the first electrolyzed water. The electrolyzed water of the device 9 is supplied to the electromagnetic valves (second purification devices) 11 and 12 as hand-washing faucets via the sterilizing water supply pump 10.

  Reference numeral 13 denotes a second electrolyzed water diluting device. Impurities (calcium, magnesium, etc. in tap water) are passed by passing tap water in the water supply pipe 1 through a pure water production device 17 comprising an activated carbon filter 14, an ion exchange resin 15 and a segment filter 16. The pure water from which the minerals are removed is supplied and the electrolyzed water is supplied from the electrolyzed water generating device 3. The electrolyzed water dilution device 13 mixes high-concentration electrolyzed water with pure water to make electrolyzed water at a low concentration (for example, effective chlorine concentration is less than 10 mg / L), and the electrolyzed water of the second electrolyzed water diluter 13 is It is supplied to the spray nozzle 19 (third purification device) for spraying the sterilized water via the sterilized water supply pump 18.

  The two-fluid spray nozzle 19 uses a two-fluid spray nozzle that mixes low-concentration electrolyzed water with air supplied from the air pump 20 and sprays it in the form of a mist. The spray nozzle 15 is a human sensor. Therefore, spraying is performed when there is no person, so that sterilization in the air can be performed without waste and without affecting the human body. Further, since the pure water from which impurities have been removed by the pure water production device 17 is used as the dilution water of the second electrolyzed water dilution device 13, impurities such as white powder are sprinkled from the spray nozzle 19 to form a floor. There is no worry of soiling surrounding structures.

  In the electrolyzed water supply system described above, two electrolyzed water diluters are used. However, as shown in FIG. 2, one electrolyzed water diluter 9 or 13 is shared, and the electromagnetic valves 11 and 12 for hand washing and the spray nozzle 19 are used. Medium concentration or low concentration electrolyzed water may be supplied.

  As shown in FIG. 3 showing the first embodiment of the electrolyzed water diluting device 9, the electrolyzed water diluting device 9 includes, for example, a diluting tank 22 with a water level sensor 21 and a water supply pipe 1 branched from the water supply pipe 1. Electrolyzed water supply pump provided in the electrolyzed water supply pipe 25 connecting the electromagnetic valve 23 and the constant flow valve 24 provided in the branch pipe 1A for supplying water (clean water) and the electrolyzed water generator 3 and the branch pipe 1A. 26, a pressure switch 27 provided in the sterilized water supply pump 10, and the electromagnetic valve 23, the electrolyzed water supply pump 26, and the sterilized water supply pump 10 are controlled according to signals from the water level sensor 21 and the pressure switch 27. It consists of the control apparatus 28, and the electrolyzed water dilution apparatus 13 is also the same structure.

  As shown in FIG. 4, the control device 28 is constituted by a microcomputer, and the signals of the water level sensor 21 and the pressure switch 27 are inputted, and the output signals of the control device 28 are the electromagnetic valve 23, the electrolyzed water supply pump 26, and the sterilization. These are output to the water supply pump 10 to control them. There are four types of signals from the water level sensor 21: an abnormal drought level L1, a normal low water level L2, a normal full water level L3, and an abnormal high water level L4, and each water level is set to L1 <L2 <L3 <L4. .

  Next, the operation of the control device 28 will be described based on the flowchart shown in FIG. First, the control device 28 determines whether or not the water level in the dilution tank 22 is below the normal full water level L3 based on the signal from the water level sensor 21 (step S01). It is determined whether or not the water level 22 is normally lower than the low water level L2 (step S02). If the water level is usually lower than the low water level L2, the electrolyzed water supply pump 26 and the electromagnetic valve 23 are turned on (step S03). ).

  For this reason, the high-concentration electrolyzed water of the electrolyzed water generating device 3 and tap water of a predetermined flow rate (pure water in the electrolyzed water diluting device 13) flow into the diluting tank 22 while mixing at a constant ratio in the branch pipe 1A. Electrolyzed water of medium concentration (low concentration or medium concentration in the electrolyzed water dilution apparatus 13) is stored in 22, and the water level of the dilution tank 22 rises. When the water level in the dilution tank 22 rises and exceeds the normal full water level L3, the control device 28 turns off the electrolyzed water supply pump 26 and the electromagnetic valve 23 (step S04), and the dilution tank 22 has an electrolysis of a predetermined concentration. Water is stored between the normal full water level L3 and the normal low water level L2.

  Then, after it is determined that it is normally lower than the low water level L2 and the electrolyzed water supply pump 26 and the electromagnetic valve 23 are turned on, or when it is determined that the water level is higher than the normal low water level L2, the dilution tank 22 Whether the water level is equal to or higher than the abnormal drought level L1 is determined by the control device 28 (step S05). And if it determines with it not being more than the abnormal drought level L1, the disinfection water supply pump 10 will not be turned ON (step S10). That is, when the water level of the dilution tank 22 falls below the normal drought level L1 due to a failure of the solenoid valve 23 or the like and there is a concern about idling, the sterilized water supply pump 10 is kept off.

  On the other hand, if it is determined that the drought water level L1 or higher, it is determined whether or not the signal of the pressure switch 27 is 0.16 MPa or less when there is no concern about idling of the sterilized water supply pump 10 (step S06). If it is determined that the pressure is not less than 16 MPa, the sterilized water supply pump 10 is not turned on (step S09), and the process returns to step S01.

  In step S06, if it is determined that it is 0.16 MPa or less, it is further determined whether it is 0.1 MPa or less (step S07). If it is determined that it is not 0.1 MPa or less, the process proceeds to step S01. Return. Moreover, if it determines with it being 0.1 Mpa or less, the disinfection water supply pump 10 will be set to ON (step S08). Thus, the pressure of the sterilized water supply pipe line is maintained between 0.1 MPa and 0.16 MPa so that the electrolyzed water in the dilution tank 22 can be taken out as sterilized water at any time from the electromagnetic valves 11 and 12 for hand washing. I have to.

  When the water level in the dilution tank 22 becomes higher than the abnormal high water level L4, an alarm is issued and the operation of the system is stopped.

  As shown in FIG. 6 showing the second embodiment of the electrolyzed water diluting device 9, the electrolyzed water diluting device 9 is connected to the diluting tank 22 from the branch pipe 1A to the ball tap 30 (the water level of the diluting tank 22 is changed to an abnormally high water level L4. The tap water at a constant water level is supplied by opening and closing the supply port), and the water in the dilution tank 22 is electrolyzed while circulating through the circulation path 33 including the circulation pump 31 and the residual chlorine sensor 32. It is mixed with high-concentration electrolyzed water in the water generating device 3 and stored in the dilution tank 22 as electrolyzed water having a predetermined concentration (medium concentration or low concentration) by the control device 28.

  As shown in FIG. 7, the signals of the residual chlorine sensor 32, the pressure switch 27, and the water level sensor 21 are input to the control device 28, and the output signals of the control device 28 are the electrolyzed water supply pump 26, the circulation pump 31, and the sterilized water supply. It is output to the pump 10, the water supply lamp 34, the sterilized water supply OK lamp 35 and the abnormal lamp 36, and these are controlled.

  Based on the flowchart shown in FIG. 8, operation | movement of the control apparatus 28 is demonstrated. First, the control device 28 determines whether the water level of the dilution tank 22 is equal to or higher than the abnormal drought level L1 based on a signal from the water level sensor 21 (step S11). 31, The electrolyzed water supply pump 26 and the sterilized water supply pump 10 are kept OFF (step S23), and the abnormal lamp 36 is turned on while the idling operation is prevented to notify the system abnormality. In this case, it is considered that water was not supplied to the dilution tank 22 due to a failure of the ball tap 30 or the like.

  Further, when it is determined that the level is equal to or higher than the abnormal drought level L1, that is, when the water level of the dilution tank 22 is maintained at a constant level by water supply through the ball tap 30, it is equal to or higher than the abnormal drought level L1. The circulation pump 31 is turned on (step S12).

  When the circulation pump 31 is operated, the water in the dilution tank 22 circulates in the circulation path 33, and the residual chlorine concentration sensor 32 detects the residual chlorine concentration (electrolyzed water concentration) of the circulating water. Here, it is determined whether or not the residual chlorine concentration is 10 mg / L or less (step S13). If it is determined that the residual chlorine concentration is 10 mg / L or less, the electrolyzed water supply pump 26 is turned on (step S14). The high concentration electrolyzed water of the water generator 3 is supplied to the circulation path 33 via the electrolyzed water supply pipe 25, and the electrolyzed water concentration of the water in the dilution tank 22 is increased. On the other hand, if it is determined that it is not less than 10 mg / L, that is, if it exceeds 10 mg / L, the electrolyzed water supply pump 26 is turned off (step S15), and high-concentration electrolyzed water is not mixed.

  As described above, when 10 mg / L is exceeded, the electrolyzed water supply pump 26 is turned off, or when it is determined that the electrolyzed water supply pump 26 is turned on when it is determined to be 10 mg / L or less, the residual chlorine concentration is then sterilized. It is determined whether it is 8 mg / L or more necessary for the above (step S16). In this case, if it is determined that it is not 8 mg / L or more, the sterilized water supply OK lamp 35 is turned off (step S18), the water supply lamp 34 is turned off and the sterilized water supply pump 10 is turned off (step S22). .

  When the residual chlorine concentration sensor 32 detects a residual chlorine concentration of 8 mg / L or more necessary for sterilization by managing the electrolytic water concentration in the dilution tank 22 (step S16), the sterilized water supply OK lamp 35 is turned on (step S16). S17).

  As described above, when the residual chlorine concentration is less than 8 mg / L as in the beginning of operation, the sanitized water supply OK lamp 35 is turned off to supply sanitized water for hand washing from the solenoid valves 11 and 12. It is made to understand whether or not.

  Next, while the sterilizing water supply OK lamp 35 is lit, it is determined whether or not the signal of the pressure switch 27 is 0.16 MPa or less (step S19). The lamp 34 is turned off and the sterilized water supply pump 10 is not turned on (step S22), and the process returns to step S01.

  In step S19, if it is determined that it is 0.16 MPa or less, it is further determined whether it is 0.1 MPa or less (step S20). If it is determined that it is not 0.1 MPa or less, the process proceeds to step S01. Return. When it is determined that the pressure of the sterilized water supply conduit is 01 MPa or less, the water supply lamp 34 is turned on and the sterilized water. The supply pump 10 is turned on (step S21). Thus, the pressure of the sterilized water supply pipe line is maintained between 0.1 MPa and 0.16 MPa so that the electrolyzed water in the dilution tank 22 can be taken out as sterilized water at any time from the electromagnetic valves 11 and 12 for hand washing. I have to.

  As shown in FIG. 9 showing a third embodiment of the electrolyzed water dilution apparatus 9, the electrolyzed water dilution apparatus 9 is configured to disinfect sterilized water through a circulation path 33 between the circulation / sterilized water supply pump 37 and the residual chlorine sensor 32. It is connected to the electromagnetic valves 11 and 12 for washing hands via a supply path 38, and a water supply switch or an infrared sensor 39 is provided in the vicinity of the electromagnetic valves 11 and 12.

  In this case as well, the water in the dilution tank 22 is mixed with the high-concentration electrolyzed water in the electrolyzed water generating device 3 in the circulation path 33 as in the electrolyzed water diluting device 9 shown in FIG. Electrolyzed water of low concentration) is stored in the dilution tank 22, and the electromagnetic valves 11 and 12 for washing hands are opened by operation of the water supply switch or detection of fingers by the infrared sensor 39, and the electrolytic water in the dilution tank 22 is sterilized water. It is supposed to be used as.

  As shown in FIG. 10, the signals of the residual chlorine sensor 32, the water level sensor 21, and the water supply switch or infrared sensor 39 are input to the control device 28, and the output signal of the control device 28 is the electrolyzed water supply pump 26, circulating / sterilized water. It is output to the supply pump 37, the solenoid valves 11, 12, the water supply lamp 34, the sterilized water supply OK lamp 35 and the abnormal lamp 36, and these are controlled.

  Based on the flowchart shown in FIG. 11, operation | movement of the control apparatus 28 is demonstrated. First, the control device 28 determines whether the water level of the dilution tank 22 is equal to or higher than the abnormal drought level L1 based on a signal from the water level sensor 21 (step S31). When it is determined that the level is not higher than the abnormal drought level L1, that is, when the level is lower than the abnormal drought level L1, the circulation / sterilization water supply pump 37 and the electrolytic water supply pump 26 remain OFF (step S44), and the idling operation is performed. The abnormality lamp 36 is turned on while preventing the system abnormality. In this case, it is considered that water was not supplied to the dilution tank 22 due to a failure of the ball tap 30 or the like in this case.

  Further, when the water level of the dilution tank 22 is maintained at a constant water level and it is determined that the level is equal to or higher than the abnormal drought level L1, the circulating / sterilizing water supply pump 37 is turned ON (step S32).

  When the circulation / sterilization water supply pump 37 (having the same function as the circulation pump 31 of the second embodiment) is operated, the water in the dilution tank 22 circulates in the circulation path 33 and the residual chlorine concentration sensor 32. Thus, the residual chlorine concentration (electrolyzed water concentration) of the circulating water is detected. Here, it is determined whether or not the residual chlorine concentration is 10 mg / L or less (step S33). If it is determined that the residual chlorine concentration is 10 mg / L or less, the electrolyzed water supply pump 26 is turned on (step S34), and the electrolyzed water generating device 3 is turned on. The high-concentration electrolyzed water is supplied to the circulation path 33 through the electrolyzed water supply pipe 25, and the electrolyzed water concentration in the dilution tank 22 is increased. When the residual chlorine concentration detected by the residual chlorine concentration sensor 32 exceeds 10 mg / L, the electrolyzed water supply pump 26 is turned off (step S35), and the high concentration electrolyzed water is not mixed. The electrolyzed water concentration of water is maintained in the vicinity of 10 mg / L.

  Next, it is determined whether or not the residual chlorine concentration sensor 32 is 8 mg / L or more necessary for sterilization (step S36), and the residual chlorine concentration sensor 32 is sterilized by the electrolytic water concentration management of the dilution tank described above. When the necessary residual chlorine concentration of 8 mg / L or more is detected, the sterilized water supply OK lamp 35 is turned on (step S37), and when the residual chlorine concentration is less than 8 mg / L as at the start of operation, sterilized water is used. By turning off the supply OK lamp 35 (step S38), it can be determined whether or not hand-washing sanitized water can be supplied from the solenoid valves 11 and 12.

  Then, while the sterilized water supply OK lamp 35 is lit, it is determined whether the water supply switch or the infrared sensor 39 is ON (step S39). When the water supply switch or the infrared sensor 39 is ON, the electromagnetic valves 11 and 12 are turned on. Turning on (step S40) and turning on the water supply lamp 34 (step S41), the circulating / sterilizing water supply pump 37 (the sterilizing water supply pump of the second embodiment) in which the electrolytic water in the dilution tank 22 is ON. 10), and supplied to the solenoid valves 11 and 12 for hand washing through the sterilizing water supply path 38 and used as sterilizing water. Further, when the sterilizing water supply OK lamp 35 is turned off or when the water supply switch or the infrared sensor 39 is not turned on, the solenoid valves 11 and 12 are turned off (step S42) and the water supply lamp 34 is turned off (step S43). Inform that water is not supplied.

  The circulation / sterilization water supply pump 37 in the third embodiment also serves as the circulation pump 31 and the sterilization water supply pump 10 of the second embodiment, and has a simple configuration and is inexpensive. It becomes composition.

  As shown in FIG. 12 which shows 4th Embodiment of the electrolyzed water dilution apparatus 9, the electrolyzed water dilution apparatus 9 is provided with the storage tank 42 provided with the water level sensor 41, and the high concentration electrolyzed water of the electrolyzed water generating apparatus 3 is supplied. The water is stored in the storage tank 42 through the electrolyzed water supply pipe 25 having the electrolyzed water supply pump 26. The branch pipe 1A for supplying tap water (clean water) is sequentially provided with a flow sensor 43, a stirrer 44, and electromagnetic valves 11 and 12 for washing hands, and the electrolyzed water in the storage tank 42 is supplied with a sterilized water supply pump 45. It is made to supply to the branch pipe 1A between the flow sensor 43 and the stirrer 44 through the disinfecting water supply pipe 46 having the above.

  The control device 47 maintains the level of the electrolyzed water in the storage tank 42 between the normal full water level L3 and the normal low water level L2 according to the signal from the water level sensor 41. The alarm is issued at an abnormally high water level L4 or higher. In addition, the discharge amount of the sterilizing water supply pump 45 is proportionally controlled according to the flow rate of tap water (clean water) flowing through the branch pipe 1A, and the high-concentration electrolyzed water is diluted and mixed to a medium concentration or a low concentration by the agitator 44. Thus, the electromagnetic valves 11 and 12 are supplied.

  As shown in FIG. 13, the control device 47 composed of a microcomputer receives signals from the flow sensor 43 and the water level sensor 41, and outputs output signals from the control device 47 to the electrolyzed water supply pump 26 and the sterilized water supply pump 45. Control these. There are four types of signals from the water level sensor 21: an abnormal drought level L1, a normal low water level L2, a normal high water level L3, and an abnormal high water level L4, and each water level is set to L1 <L2 <L3 <L4. .

  Based on the flowchart shown in FIG. 14, operation | movement of the control apparatus 47 is demonstrated. First, the control device 47 determines whether or not the water level of the storage tank 42 is below the normal full water level L3 based on the signal from the water level sensor 41 (step S51). It is determined whether the water level of 42 is below the normal low water level L2 (step S52), and when it is below the normal low water level L2, the electrolyzed water supply pump 26 is turned on (step S53).

  For this reason, the high concentration electrolyzed water of the electrolyzed water production | generation apparatus 3 flows in into the fraction storage tank 42 via the electrolyzed water supply pipe 25, and the water level of the storage tank 42 rises. When the water level in the storage tank 42 rises and exceeds the normal full water level L3, the electrolyzed water supply pump 26 is turned off (step S54), and high concentration electrolyzed water is stored in the storage tank 42 at the normal full water level L3. Water is stored between the low water level L2.

  And when the water level of the storage tank 42 is not below the normal full water level L3, when it is below the normal full water level L3 and not below the normal low water level L2, or below the normal full water level L3 and below the normal low water level. After the electrolyzed water supply pump 26 is turned on at L2 or less, it is next determined whether or not the water level in the water storage tank 42 is above the abnormal drought level L1 (step S55).

  In this case, when there is no concern about the idling operation of the sterilized water supply pump 45 at the abnormal drought level L1 or higher, the flow rate sensor 43 detects the flow rate of tap water (clean water) flowing through the branch pipe 1A and the sterilized water supply pump By turning ON 45 and proportionally controlling the discharge amount of the sterilized water supply pump 45 in accordance with the signal from the flow sensor 43 (step S56), the agitator 44 changes the high concentration electrolyzed water to a medium concentration or a low concentration. The electrolyzed water diluted to a predetermined concentration can be taken out as sterilized water at any time from the electromagnetic valves 11 and 12 for hand washing, after being diluted and mixed and supplied to the electromagnetic valves 11 and 12.

  If the water level of the storage tank 42 falls below the abnormal drought level L1 due to a failure of the electrolyzed water supply pump 26 or the like and there is a concern about idling, the sterilized water supply pump 45 is kept OFF (S57). When the water level in the storage tank 42 becomes an abnormal high water level L4 or higher, an alarm is issued and the system operation is stopped.

  Although not shown, the electrolyzed water dilution device 9 does not include the storage tank 42, and the high-concentration electrolyzed water of the electrolyzed water generating device 3 is connected to the flow rate sensor 43 via the electrolyzed water supply pipe having the electrolyzed water supply pump 26.
