[0007] (First embodiment) FIG. 1 is a diagram showing the configuration of an electrolyzed water generating device 1. As shown in FIG. The electrolyte aqueous solution tank 11 stores an appropriate electrolyte aqueous solution. When the electrolytic water generator 1 generates slightly acidic electrolyzed water with an effective chlorine concentration of 10 to 80 ppm and a pH of 5.0 to 6.5, hydrochloric acid or a solution obtained by adding sodium chloride aqueous solution to hydrochloric acid can be used as the electrolyte aqueous solution. When the electrolytic water generator 1 generates electrolyzed hypochlorous water with an effective chlorine concentration of 10 to 80 ppm and a pH of 7.5 or higher, a sodium chloride aqueous solution can be used as the electrolyte aqueous solution.

[0008] The pump 12 sucks the aqueous electrolyte solution from the aqueous electrolyte solution tank 11 and sends it to the electrolytic cell 13 .

[0009] The electrolytic cell 13 is a single-chambered cell, and its interior is not partitioned by a diaphragm. The electrolytic cell 13 electrolyzes the electrolyte aqueous solution by applying a voltage of a certain value or higher corresponding to the electrolyte aqueous solution to a pair of electrodes contained therein, thereby producing an electrolytic solution. In the electrolytic water generator 1, when hydrochloric acid or a solution of sodium chloride added thereto is used as the electrolyte aqueous solution, applying a voltage of, for example, 1.5 V or higher results in a satisfactory amount of chlorine generation (the production of a satisfactory electrolytic solution), enabling the electrolytic water generator 1 to produce a satisfactory amount of slightly acidic electrolytic water. Appropriate gases generated during electrolysis, such as hydrogen and chlorine, may be separated from the electrolytic solution by a separation mechanism (not shown) provided in the electrolytic cell 13 and discharged to the outside, or may be discharged from the electrolytic cell 13 together with the electrolytic solution. The pump 12 sends the electrolyte aqueous solution to the electrolytic cell 13, and the electrolytic solution is then sent from the electrolytic cell 13 to the dilution flow path 14 via piping 18.

[0010] The dilution flow path 14 is supplied with raw water (water for diluting the electrolytic solution, dilution water) such as tap water or RO (Reverse Osmosis) water from the water supply unit 15. In this embodiment, the water supply unit 15 is connected to a water supply, and the raw water supplied from the water supply unit 15 to the dilution flow path 14 is subjected to water pressure from the water supply. The dilution flow path 14 dilutes the electrolytic solution sent from the electrolytic cell 13 with the dilution water flow to produce electrolyzed water. For example, the dilution flow path 14 dilutes the electrolytic solution produced in the electrolytic cell 13 with the raw water flow so that the solution meets the requirements for slightly acidic electrolyzed water (effective chlorine concentration 10 to 80 ppm, pH 5.0 to 6.5), thereby producing electrolyzed water. The dilution flow path 14 discharges the produced electrolyzed water from the electrolyzed water discharge unit 17.

[0011] The impeller 16 is provided in the dilution flow path 14 to generate electricity to supply to both the electrolytic cell 13 and the pump 12, and is rotated by the flow of raw water. In the dilution flow path 14, an inflow point 141 for the electrolyzed water solution from the electrolytic cell 13 is located downstream of the impeller 16, but may be located upstream of the impeller 16, as shown in the position of (A) in Figure 1. When the inflow point 141 is located upstream of the impeller 16, the impeller 16 can effectively stir the electrolytic water solution when diluting and mixing it.

[0012] The battery 2 is provided as a backup to supply power to the electrolytic cell 13 in the event that the flow of raw water supplied from the water supply unit 15 weakens and power generation is hindered. The battery 2 may be an external battery of the electrolyzed water generator 1, or may be connected to the electrolyzed water generator 1.

[0013] The gear mechanism 31 distributes the torque transmitted from the impeller 16 to the first generator 32 and the second generator 33. For example, the gear mechanism 31 distributes more torque to the first generator 32 than to the second generator 33 so that the amount of power generated by the first generator 32 is greater than the amount of power generated by the second generator 33. The gear mechanism 31 may increase the speed of the rotation transmitted from the impeller 16 and transmit it to the first generator 32 and the second generator 33 to facilitate power generation. The gear mechanism 31 may be configured as an appropriate planetary gear mechanism or the like, and may also include a torque transmission mechanism including a belt, a chain, or the like.

[0014] The first generator 32 generates electricity using torque transmitted from the impeller 16 via the gear mechanism 31. The first generator 32 supplies the generated electricity to the electrolyzer 13 and / or the battery 2 via a first power supply circuit 34.

[0015] The first power supply circuit 34 has a switching element and, under the control of the control unit 37, connects and disconnects the first generator 32, the electrolytic cell 13, and the input terminal of the battery 2, and connects and disconnects the output terminal of the battery 2 and the electrolytic cell 13. The first power supply circuit 34 also performs processes such as AC-DC conversion on the voltage input from the first generator 32. A diode 38 is provided between the first power supply circuit 34 and the input terminal of the battery 2 to charge the battery 2 with more than a predetermined amount of power generation.

[0016] The second generator 33 generates electricity using torque transmitted from the impeller 16 via the gear mechanism 31. The second generator 33 supplies the generated electric power to the pump 12 via a second power supply circuit 35. The second generator 33 may be smaller than the first generator 32.

[0017] The second power supply circuit 35 performs processing such as AC-DC conversion on the voltage input from the second generator 33 and outputs the resulting voltage to the pump 12 .

[0018] The voltage sensor 36 detects the output voltage of the first power supply circuit 34 (first generator 32) or the second power supply circuit 35 (second generator 33), and outputs the detected value to the control unit 37. Instead of the voltage sensor 36, a sensor may be provided that detects an index corresponding to the output power of the first power supply circuit 34 (first generator 32) and the second power supply circuit 35 (second generator 33), such as the rotation speed of the impeller 16 or the flow rate of the dilution flow path 14.

[0019] The control unit 37 is configured to include appropriate circuit elements such as a comparator, a memory, and a processor that reads and executes a program from the memory, and controls the first power supply circuit based on the output of the voltage sensor .

[0020] In the electrolyzed water generator 1 described above, torque obtained by the impeller 16 from the water flow in the dilution flow path 14 is transmitted to the first generator 32 and the second generator 33 to generate electricity. The pump 12 is driven by a portion of the generated power (for the second generator 33), and the electrolyte aqueous solution is sent to the electrolytic cell 13, while a portion of the generated power (for the first generator 32) is supplied to the electrolytic cell 13 to perform electrolysis. An electrolytic product solution is pushed out from the electrolytic cell 13 in an amount equal to the amount of electrolyte aqueous solution sent to the electrolytic cell 13 by the pump 12, and sent to the dilution flow path 14 where it is diluted. As a result, electrolyzed water is generated in the dilution flow path 14, and the electrolyzed water is discharged from the electrolyzed water discharge unit 17.

[0021] In the electrolyzed water generator 1, the pump 12 is driven by electricity generated using the torque obtained by the impeller 16, so there is no need to provide a complex speed reducer mechanism between the impeller 16 and the pump 12. In the electrolyzed water generator 1, the pump 12 only needs to be connected to the second power supply circuit 35, which increases the flexibility in the installation position of the pump 12.

[0022] In the electrolyzed water generator 1, the flow rate of the dilution flow path 14 is proportional to the power generated by the second generator 33 for the pump 12, so when the flow rate of the dilution flow path 14 is high, the amount of electrolyte aqueous solution supplied to the electrolytic cell 13 increases, and when the flow rate of the dilution flow path 14 is low, the amount of electrolyte aqueous solution supplied to the electrolytic cell 13 decreases. In this way, in the electrolyzed water generator 1, the amount of electrolyte aqueous solution supplied to the electrolytic cell 13 can be automatically adjusted according to the flow rate of the dilution flow path 14.

[0023] Here, when the flow rate through the dilution flow path 14 becomes very small and the pump 12 no longer supplies the electrolytic aqueous solution to the electrolytic cell 13, the electrolytic solution is no longer forced out of the electrolytic cell 13 into the dilution flow path 14. In such a case, the electrolytic cell 13 is supplied with power as usual, and the electrolytic aqueous solution in the electrolytic cell 13 continues to be electrolyzed. This is referred to as "dry-fired" in this specification. When dry-fired occurs, for example, water in the electrolytic aqueous solution is electrolyzed (including reduction of hydrogen ions and oxidation of hydroxide ions) to form oxygen gas and hydrogen gas, which are then removed from the electrolytic aqueous solution, increasing the concentration of the electrolytic aqueous solution. Then, while the amount of electrolytic aqueous solution in the electrolytic cell 13 decreases, the amount of current passing through the electrolytic aqueous solution increases, which may cause abnormal heating and damage to the electrodes. However, in the electrolyzed water generating device 1, the flow rate in the dilution flow path 14 is proportional to the power generated by the first generator 32 for the electrolytic cell 13, so when the flow rate in the dilution flow path 14 decreases, the power generated by the first generator 32 supplied to the electrolytic cell 13 automatically decreases, thereby preventing the electrolytic cell 13 from running dry.

[0024] The electrolytic water generating device 1 is provided with a first generator 32 for the electrolytic cell 13 and a second generator 33 for the pump 12, and the torque obtained by the impeller 16 is distributed between them by a gear mechanism 31, so that each element can be constructed using general-purpose parts.

[0025] An example of the power supply process by the control unit 37 will be described below with reference to the flowchart of FIG. 2 in addition to FIG.

[0026] When the control unit 37 determines, based on the output of the voltage sensor 36, that the output voltage of the first power supply circuit 34 (first generator 32) to the electrolytic cell 13 is at or above a level suitable for electrolysis (step S1: YES), the control unit 37 connects the first generator 32 to the input terminals of the electrolytic cell 13 and the battery 2 via the first power supply circuit 34, and supplies the output power of the first power supply circuit 34 (first generator 32) to the electrolytic cell 13 and the battery 2 (step S2). The level suitable for electrolysis may be the output voltage level of the first power supply circuit 34 (first generator 32) at which a voltage is applied to the electrolytic cell 13 at which the electrolytic product solution begins to be produced satisfactorily in the electrolytic cell 13. At this time, the pump 12 is driven by the second power supply circuit 35 (second generator 33), and the aqueous electrolyte solution is sent to the electrolytic cell 13, where electrolysis occurs.

[0027] In this way, the electrolyzed water generator 1 performs electrolysis using the power generated by the first generator 32 when the water flow in the dilution flow path 14 is at a normal flow rate.

[0028] If the control unit 37 determines based on the output of the voltage sensor 36 that the output voltage of the first power supply circuit 34 (first generator 32) to the electrolytic bath 13 is lower than a level suitable for electrolysis (step S1: NO), or if the control unit 37 determines that the output voltage of the second power supply circuit 35 (second generator 33) is at or above a level capable of driving the pump 12 (step S3: YES), it connects the output terminal of the battery 2 to the electrolytic bath 13 via the first power supply circuit 34, supplies the output power of the battery 2 to the electrolytic bath 13, and continues electrolysis (step S4). Thereafter, if the control unit 37 determines that the output voltage of the second power supply circuit 35 (second generator 33) is lower than a level capable of driving the pump 12 (step S3: NO), it disconnects the first generator 32 from the electrolytic bath 13 via the first power supply circuit 34 (step S5).

[0029] In this way, even if the water flow in the dilution flow path 14 weakens and the power generation power of the first generator 32 decreases, as long as the pump 12 can be driven, the power source for the electrolytic cell 13 will be switched from the first generator 32 to the battery 2, and the power supply to the electrolytic cell 13 will continue without being cut off, so that the electrolytic water generating device 1 can continuously generate electrolytic water.

[0030] After step S5, if the control unit 37 determines that the output voltage of the first power supply circuit 34 (first generator 32) is equal to or higher than the minimum level of the charging voltage of the battery 2 (capable of passing current through the diode 38) (step S6: YES), the control unit 37 connects the first generator 32 to the input terminal of the battery 2 via the first power supply circuit 34 and supplies the output power of the first power supply circuit 34 (first generator 32) to the battery 2 (step S7).

[0031] In this way, when the water flow in the dilution flow path 14 weakens and it becomes difficult to drive the pump 12, the electrolyzed water generating device 1 uses the generated power of the first generator 32 to charge the battery 2, thereby making effective use of the generated energy.

[0032] After step S5, if the control unit 37 determines that the output voltage of the first power supply circuit 34 (first generator 32) is lower than the minimum level of the charging voltage of the battery 2 (step S6: NO), it disconnects the first power supply circuit 34 from the battery 2 (step S8).

[0033] In this way, when the water flow in the dilution flow path 14 weakens and the generated power of the first generator 32 drops to the point where it cannot be used to charge the battery 2, the electrolyzed water generating device 1 will not charge using the generated power.

[0034] (Second embodiment) FIG. 3 is a diagram showing the configuration of the electrolyzed water generating device 1A. In the electrolyzed water generator 1A, the third generator 32A generates electricity using torque transmitted from the impeller 16 and supplies the generated electricity to the electrolytic cell 13 and the pump 12 via the third power supply circuit 34A. The voltage sensor 36 detects the output voltage of the third power supply circuit 34A (third generator 32A) and outputs the detected value to the control unit 37. Instead of the voltage sensor 36, a sensor may be provided that detects an index corresponding to the output power of the third power supply circuit 34A (third generator 32A), such as the rotation speed of the impeller 16 or the flow rate of the dilution flow path 14.

[0035] The third power supply circuit 34A has a switching element and, under the control of the control unit 37, connects and disconnects the third generator 32A to and from the input terminal of the electrolytic cell 13 and the battery 2, and connects and disconnects the output terminal of the battery 2 to and from the electrolytic cell 13. The third power supply circuit 34A constantly connects the third generator 32A to the pump 12. The third power supply circuit 34A also performs processes such as AC-DC conversion on the voltage input from the third generator 32A. The third power supply circuit 34A distributes the voltage of the third generator 32A to the electrolytic cell 13 and the pump 12 at a set ratio, but the output voltage to the electrolytic cell 13 and the pump 12 may be changed based on the output voltage of the third power supply circuit 34A (third generator 32A) detected by the voltage sensor 36. The remaining configuration of the electrolyzed water generator 1A is similar to that of the electrolyzed water generator 1.

[0036] As with the electrolyzed water generator 1, the electrolyzed water generator 1A does not require a complex speed reduction mechanism between the impeller 16 and the pump 12, and the pump 12 only needs to be connected to the third power supply circuit 34A, increasing the degree of freedom in installation location. The electrolyzed water generator 1A can also automatically adjust the amount of electrolyte aqueous solution supplied to the electrolytic cell 13 according to the flow rate in the dilution flow path 14, and when the flow rate in the dilution flow path 14 decreases, the generated power of the third generator 32A supplied to the electrolytic cell 13 is automatically reduced, so that, as with the first embodiment, dry-running of the electrolytic cell 13 can be prevented.

[0037] An example of the power supply process by the control unit 37 will be described below with reference to the flowchart of FIG. 4 in addition to FIG. When the control unit 37 determines, based on the output of the voltage sensor 36, that the output voltage of the third power supply circuit 34A (third generator 32A) to the electrolytic cell 13 is at or above a level suitable for electrolysis (step S11: YES), it connects the third generator 32A to the input terminals of the electrolytic cell 13 and the battery 2 via the third power supply circuit 34A, and supplies the power generated by the third generator 32A to the electrolytic cell 13 and the battery 2 (step S12). At this time, the pump 12 is driven by the third power supply circuit 34A (third generator 32A), the aqueous electrolyte solution is sent to the electrolytic cell 13, and electrolysis occurs in the electrolytic cell 13.

[0038] In this way, when the water flow in the dilution flow path 14 is at a normal flow rate, the electrolyzed water generator 1A performs electrolysis using the power generated by the third generator 32A.

[0039] If the control unit 37 determines based on the output of the voltage sensor 36 that the output voltage of the third power supply circuit 34A (third generator 32A) to the electrolytic cell 13 is lower than a level suitable for electrolysis (step S11: NO), or if the control unit 37 determines that the output voltage of the third power supply circuit 34A (third generator 32A) to the pump 12 is at or above a level capable of driving the pump 12 (step S13: YES), the control unit 37 connects the output terminal of the battery 2 to the electrolytic cell 13 via the third power supply circuit 34A, supplies the output power of the battery 2 to the electrolytic cell 13, and continues electrolysis (step S14). Thereafter, if the control unit 37 determines that the output voltage of the third generator 32A to the pump 12 is lower than a level capable of driving the pump 12 (step S13: NO), the control unit 37 disconnects the third generator 32A from the electrolytic cell 13 via the third power supply circuit 34A (step S15).

[0040] In this way, even if the water flow in the dilution flow path 14 weakens and the power generation power of the third generator 32A decreases, as long as the pump 12 can be driven, the electrolytic water generating device 1A switches the power source for the electrolytic cell 13 from the third generator 32A to the battery 2 and continues to generate electrolytic water.

[0041] After step S15, if the control unit 37 determines that the output voltage of the third power supply circuit 34A (third generator 32A) to the battery 2 is equal to or higher than the minimum level of the charging voltage of the battery 2 (step S16: YES), the control unit 37 connects the third generator 32A to the input terminal of the battery 2 via the third power supply circuit 34A and supplies the output power of the third power supply circuit 34A (third generator 32A) to the battery 2 (step S17).

[0042] In this way, when the water flow in the dilution flow path 14 weakens and it becomes difficult to drive the pump 12, the electrolyzed water generating device 1A uses the generated power of the third generator 32A to charge the battery 2, thereby making effective use of the generated energy.

[0043] After step S15, if the control unit 37 determines that the output voltage of the third power supply circuit 34A (third generator 32A) to the battery 2 is lower than the minimum level of the charging voltage of the battery 2 (step S16: NO), it disconnects the third power supply circuit 34A from the battery 2 (step S18).

[0044] In this way, when the water flow in the dilution flow path 14 weakens and the generated power of the third generator 32A drops to the point where it cannot be used to charge the battery 2, the electrolyzed water generating device 1A will not charge the battery 2 using the generated power.

[0045] (Third embodiment) FIG. 5 is a diagram showing the configuration of the electrolyzed water generating device 1B. In the electrolyzed water generator 1B, the fourth generator 33B generates electricity using the torque transmitted from the impeller 16, and supplies the electricity to the pump 12 via the fourth power supply circuit 35B. The fourth power supply circuit 35B performs processing such as AC-DC conversion on the voltage input from the fourth generator 33B, and outputs the resulting voltage to the pump 12.

[0046] The battery 2 supplies power to the electrolytic bath 13 via a fifth power supply circuit 34B. The fifth power supply circuit 34B has a switching element and connects and disconnects the output terminal of the battery 2 to the electrolytic bath 13 under the control of the control unit 37. The voltage sensor 36 detects the output voltage of the fourth power supply circuit 35B (fourth generator 33B) and outputs the detected value to the control unit 37. Instead of the voltage sensor 36, a sensor that detects an index corresponding to the output power of the fourth power supply circuit 35B (fourth generator 33B), such as the rotation speed of the impeller 16 or the flow rate of the dilution flow path 14, may be provided. The control unit 37 disconnects the connection between the fifth power supply circuit 34B and the battery 2 when it determines that the output voltage of the fourth power supply circuit 35B (fourth generator 33B) is lower than a level capable of driving the pump 12.

[0047] As with the electrolyzed water generator 1, the electrolyzed water generator 1B does not require a complex speed reduction mechanism between the impeller 16 and the pump 12, and the pump 12 only needs to be connected to the fourth power supply circuit 35B, which increases the flexibility of its installation location. The electrolyzed water generator 1B can also automatically adjust the amount of electrolyte aqueous solution supplied to the electrolytic cell 13 according to the flow rate in the dilution flow path 14, and when the flow rate in the dilution flow path 14 becomes so low that it cannot drive the pump 12, the power supply from the battery 2 to the electrolytic cell 13 is stopped, thereby preventing the electrolytic cell 13 from running dry.

[0048] The present invention can be implemented in the embodiments without departing from its features. The embodiments, variations, and effects are merely illustrative and should not be construed as limiting the present invention. The features and structures of the embodiments and variations can be added and combined in various ways to obtain alternative configurations. [Explanation of symbols]
