Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a schematic configuration of an electrolyzed water generating apparatus 1 of the present embodiment. In the present embodiment, as the electrolyzed water generating device 1, for example, a home electrolyzed water generating device used for generating home drinking water is shown.

  The electrolyzed water generating device 1 includes a main body 2 that generates electrolyzed water and a faucet 6 that discharges and stops the electrolyzed water.

  The main body 2 includes a water purification cartridge 3 for purifying raw water and an electrolytic tank 5 in which an electrolysis chamber 4 for electrolyzing the purified water is formed. For example, the main body 2 is stored below a sink in a kitchen.

  Raw water is supplied to the water purification cartridge 3. As the raw water, tap water is generally used, but well water, ground water, and the like can be used. The purified water cartridge 3 purifies the raw water by filtration and supplies the obtained purified water to the electrolysis chamber 4.

  Inside the electrolysis chamber 4, an anode power supply 41 and a cathode power supply 42 are arranged to face each other. A diaphragm 43 is disposed between the anode power supply 41 and the cathode power supply 42. The diaphragm 43 divides the electrolysis chamber 4 into an anode chamber 4a on the anode power supply 41 side and a cathode chamber 4b on the cathode power supply 42 side.

  Water is supplied to both the anode chamber 4 a and the cathode chamber 4 b of the electrolysis chamber 4, and a DC voltage is applied to the anode power supply 41 and the cathode power supply 42, whereby water is electrolyzed in the electrolysis chamber 4.

  The diaphragm 43 allows ions generated by electrolysis to pass through. The anode power supply 41 and the cathode power supply 42 are electrically connected via the diaphragm 43. By electrolyzing water in the electrolysis chamber 4, electrolytic reduced water is obtained in the cathode chamber 4b, and electrolytic acid water is obtained in the anode chamber 4a.

  In the cathode chamber 4b, hydrogen gas is generated by electrolysis and dissolves in the water in the cathode chamber 4b. Therefore, the electrolytically reduced water obtained in the cathode chamber 4b is also referred to as electrolytic hydrogen water, and is effective for removing active oxygen.

  The electrolytically reduced water obtained in the cathode chamber 4b and the electrolytic acid water obtained in the anode chamber 4a are supplied to the faucet portion 6 via the flow path switching valve 21 and discharged. The flow path switching valve 21 is configured to be able to switch the connection destination while separating the flow path of the electrolytically reduced water obtained in the cathode chamber 4b and the flow path of the electrolytic acid water obtained in the anode chamber 4a. Yes.

  The faucet unit 6 includes an operation unit (mode switching means) 7 operated by a user, a water discharge port 8 for discharging electrolytic reduced water or electrolytic acidic water obtained in the electrolysis chamber 4, and electrolytic acidic water or electrolytic reduced water. A drain outlet 9 that discharges water, a human body detection sensor 13 that detects a human body in a non-contact manner, a solenoid valve (water discharge control means) 14 that supplies raw water to the main body 2, and a control that controls each part of the electrolyzed water generator 1. Unit (mode switching means, water discharge control means) 15.

  FIG. 2 shows the appearance of the faucet part 6. The faucet part 6 is installed, for example, around the sink of the kitchen. The faucet part 6 of the present embodiment is a mixed faucet that performs raw water, hot water discharge, and water stopping in addition to purified water and electrolytic water.

  The faucet part 6 of the present embodiment includes a first handle that is operated by the user when discharging raw water or hot water, in addition to the operation part 7, the water discharge port 8, the drainage port 9, the human body detection sensor 13, and the control unit 15. 11 and a second handle 12 operated by a user when discharging purified water or electrolyzed water.

  The operation unit 7 of the present embodiment is configured by a touch panel. As the touch panel, for example, a capacitive touch panel, a pressure sensitive touch panel, and the like disclosed in JP2013-138996A can be applied. The operation unit 7 outputs a signal corresponding to the touch operation to the control unit 15.

  The user can switch the water discharge mode of the electrolyzed water generating device 1 by touching the operation unit 7. The switchable water discharge mode includes a “reduced water mode” in which electrolytic reduced water is discharged from the faucet unit 6 and an “acidic water mode” in which electrolytic acid water is discharged from the faucet unit 6.

  The water discharge port 8 discharges raw water and hot water in addition to electrolytically reduced water or electrolytic acid water selected by switching the water discharge mode. That is, when the water discharge mode is “reduced water mode”, electrolytic reduced water is discharged from the water discharge port 8, and when the water discharge mode is “acid water mode”, electrolytic acidic water is discharged from the water discharge port 8. The selected electrolyzed water is discharged from the water discharge port 8 by the above-described flow path switching valve 21 switching the flow path communicating with the cathode chamber 4b and the flow path communicating with the anode chamber 4a.

  The drain 9 discharges the electrolytic acid water or the electrolytic reduced water that was not selected by switching the water discharge mode. That is, when the water discharge mode is the “reduced water mode”, the electrolytic acid water is discharged from the drain port 9, and when the water discharge mode is the “acid water mode”, the electrolytic reduced water is discharged from the drain port 9. When the flow path switching valve 21 switches the flow path communicating with the cathode chamber 4b and the flow path communicating with the anode chamber 4a, the electrolyzed water that has not been selected is discharged from the drain port 9. In the present embodiment, the drain port 9 is formed by a pipe having a smaller diameter than the water discharge port 8.

  The first handle 11 is, for example, a mixing plug that is operated when the raw water or hot water is manually discharged from the water outlet 8. The second handle 12 is operated when the purified water or the electrolyzed water is manually discharged from the water outlet 8. About the 1st handle 11 and the 2nd handle 12, since it is equivalent to what is indicated by JP, 2013-138996, the explanation is omitted.

  The human body detection sensor 13 includes, for example, an infrared detector that detects infrared rays, and detects the human body in a non-contact manner by detecting infrared rays emitted from the human body or reflected by the human body. In the case of the latter, it has an infrared irradiation part which irradiates infrared rays. In the present embodiment, the human body detection sensor 13 is provided, for example, in front of the water outlet 8. When the user holds his / her hand in front of the water discharge port 8, the human body is detected by the human body detection sensor 13.

  The electromagnetic valve 14 shown in FIG. 1 is provided on the upstream side of the water purification cartridge 3. The electromagnetic valve 14 opens and closes according to the operation of the second handle 12 and the detection result of the human body detection sensor 13. The supply of raw water to the water purification cartridge 3 is controlled by opening and closing the electromagnetic valve 14, and consequently, electrolyzed water discharged from the water outlet 8 is controlled.

  The control unit 15 is mounted inside the faucet unit 6. The control unit 15 may be provided on the main body unit 2 side. The control unit 15 controls each unit of the electrolyzed water generating device 1 according to signals input from the operation unit 7 and the human body detection sensor 13. For example, the control unit 15 controls the DC voltage applied to the anode power supply 41 and the cathode power supply 42. Further, the control unit 15 controls the communication state of the cathode chamber 4 b and the anode chamber 4 a with the water discharge port 8 and the drain port 9 by controlling the flow path switching valve 21. Furthermore, the control unit 15 controls the supply of purified water to the electrolysis chamber 4 by controlling the opening / closing operation of the electromagnetic valve 14, and consequently controls the discharge or stop of the electrolyzed water from the water outlet 8.

  FIG. 3 shows one mode of operation of the control unit 15 of the electrolyzed water generating apparatus 1. When the human body detection sensor 13 detects the human body (S1) and the water discharge mode is the “reduced water mode” (YES in S2), the control unit 15 opens the electromagnetic valve 14 and also supplies the anode feeder. A DC voltage is applied to 41 and the cathode power supply 42 to generate electrolytic reduced water in the cathode chamber 4b (S3). And the control part 15 controls the flow-path switching valve 21, and discharges electrolytic reduction water from the water discharge port 8 (S4). Thereby, electrolyzed reduced water is discharged from the spout 8 by a simple operation such as a hand-holding by the user, and the usability of the electrolyzed water generating apparatus 1 is improved.

  On the other hand, when the water discharge mode is not the “reduced water mode” (NO in S2), that is, when the water discharge mode is the “acid water mode”, the control unit 15 discharges the electrolytic acidic water from the water discharge port 8. Prevent (S5).

  The discharge of the electrolytic acid water can be prevented by, for example, stopping the power supply to the anode power supply body 41 and the cathode power supply body 42 by the control unit 15. In this case, since electrolysis does not occur in the electrolysis chamber 4, neutral water is discharged from the water outlet 8. This neutral water is purified water purified by the water purification cartridge 3.

  Prevention of discharge of electrolytic acid water can also be performed by the controller 15 closing the electromagnetic valve 14, for example. In this case, electrolyzed water or purified water is not discharged from the water outlet 8. Moreover, it is also possible to avoid discharge of electrolytic acid water by providing a separate solenoid valve downstream of the anode chamber 4a.

  By preventing the discharge of electrolytic acid water from the water discharge port 8 in this way, it is possible to prevent the user from unintentionally discharging the electrolytic acid water from the water discharge port 8, and to prevent misuse of the electrolytic acid water. It becomes possible.

  As already described, even when the water discharge mode is the “acid water mode”, the user can discharge the electrolytic acid water from the water discharge port 8 by operating the second handle 12. However, in this case, since the user consciously touches and operates the second handle 12 that physically exists, misuse of electrolytic acid water is suppressed as in the conventional electrolyzed water generating device.

  FIG. 4 shows an electrolyzed water generating device 1 </ b> A that is another embodiment of the electrolyzed water generating device 1. The electrolyzed water generating apparatus 1A has a pH detection means 22 for detecting the pH value of electrolyzed reduced water in the main body 2A. The pH detection means 22 includes a flow rate sensor 23 that detects the flow rate of water supplied to the electrolysis chamber 4, and an ammeter 24 that detects the current flowing through the anode feeder 41.

  The flow sensor 23 is provided between the water purification cartridge 3 and the electrolysis chamber 4. The flow sensor 23 may be arranged on the upstream side of the water purification cartridge 3. Since the currents flowing through the anode power supply 41 and the cathode power supply 42 are equal, the ammeter 24 may detect the current flowing through the cathode power supply 42.

  The pH value of the electrolyzed water generated in the electrolysis chamber 4 depends on the flow rate of the water supplied to the electrolysis chamber 4 and the current flowing through the anode feeder 41. Therefore, the control unit 15 can calculate the pH value based on the flow rate detected by the flow rate sensor 23 and the current detected by the ammeter 24. In this case, the control unit 15 functions as a pH calculation unit, and the flow sensor 23, the ammeter 24, and the control unit 15 function as a pH detection unit.

  Instead of the pH sensor 22 including the flow rate sensor 23, the ammeter 24, and the control unit 15 described above, for example, a pH sensor using a glass electrode may be applied.

  1 A of electrolyzed water generating apparatuses have the flow-path switching valve 16 and the drain port 17 in the faucet part 6A. The flow path switching valve 16 is provided between the flow path switching valve 21 and the water discharge port 8. The flow path switching valve 16 switches the flow path flowing from the flow path switching valve 21 to the water discharge port 8 or the drain port 17. Instead of the drain port 17, the flow path switching valve 16 and the drain port 9 may be connected.

  FIG. 5 shows one mode of operation of the control unit 15 of the electrolyzed water generating apparatus 1A. In this embodiment, “water purification mode” in which purified water is discharged from the water outlet 8 is included as the water discharge mode. In addition, it is determined whether or not electrolytic reduced water is discharged from the water outlet 8 according to the pH value of the electrolytic reduced water.

  When the human body detection sensor 13 detects a human body (S11) and the water discharge mode is the “water purification mode” (YES in S12), the control unit 15 applies a DC voltage to the anode power supply 41 and the cathode power supply 42. The electromagnetic valve 14 is opened without applying. Thereby, the neutral purified water without electrolysis passes through the electrolysis chamber 4, and is discharged from the spout 8 (S13). Note that the operation of the “water purification mode” can also be appropriately employed in the electrolyzed water generating apparatus 1 shown in FIGS. 1 and 3.

  When the water discharge mode is the “reduced water mode” (NO in S12, YES in S14), the control unit 15 opens the electromagnetic valve 14 and applies a DC voltage to the anode power supply 41 and the cathode power supply 42. Then, electrolytic reduced water is generated in the cathode chamber 4b (S15). The electrolytically reduced water produced here is first used to detect the pH value. That is, the control unit 15 calculates the pH value based on the flow rate detected by the flow rate sensor 23 and the current detected by the ammeter 24 (S16).

  Furthermore, the control unit 15 determines whether or not the pH value of the electrolytically reduced water is within a range suitable for drinking (S17). The range of pH value suitable for drinking is determined in advance, and is, for example, 7 to 10 in this embodiment. When it is determined that the pH value of the electrolytically reduced water is within the range suitable for drinking (YES in S17), the control unit 15 continues to generate electrolytically reduced water in the cathode chamber 4b, and the flow path switching valve 21 and The flow path switching valve 16 is controlled to discharge electrolytic reduced water from the water outlet 8 (S18).

  On the other hand, when it is determined that the pH value of the electrolytically reduced water is outside the range suitable for drinking (NO in S17), the control unit 15 stops the power supply to the anode power supply 41 and the cathode power supply 42, and the electromagnetic valve 14 And the flow path switching valve 21 and the flow path switching valve 16 are controlled to discharge the electrolytically reduced water generated for detecting the pH value from the drain port 17 (S19). This suppresses misuse of electrolytically reduced water having a high pH value.

  When the water discharge mode is not the “reduced water mode” in S14 (NO in S14), that is, when the water discharge mode is the “acidic water mode”, the control unit 15 controls the water outlet 8 as in S5 in FIG. The discharge of electrolytic acid water from is prevented (S20).

  FIG. 6 shows another form of operation of the control unit 15 of the electrolyzed water generating apparatus 1A. In this form, the pH value range suitable for drinking is set in two stages according to the period after the use of the electrolyzed water generator 1A is started. The control unit 15 has a timer for counting the date and time. The period from the start of use of the electrolyzed water generating apparatus 1A is counted by the control unit 15. The pH value suitable for drinking is set low, assuming that the user is not used to electrolytically reduced water until a predetermined period T elapses from the start of use of the electrolyzed water generator 1A. . The predetermined period T is preferably about 2 to 5 days, for example.

  In FIG. 6, S21 to S26 are the same as S11 to S16 shown in FIG. Subsequent to S26, if a predetermined period T has elapsed since the start of use of the electrolyzed water generating apparatus 1A (YES in S27), the control unit 15 is suitable for drinking in which the pH value of electrolyzed reduced water continues. It is determined whether it is within the range (S28). The range of the pH value suitable for continued drinking is determined in advance, and is, for example, 7 to 10 in this embodiment.

  When it is determined that the pH value of the electrolytically reduced water is within the range suitable for continuous drinking (YES in S28), the control unit 15 discharges the electrolytically reduced water from the water outlet 8 (S29), similarly to S18. On the other hand, when it is determined that the pH value of the electrolytically reduced water is outside the range suitable for continuous drinking (NO in S28), as in S19, power supply to the anode power supply 41 and the cathode power supply 42 is stopped, and electromagnetic The valve 14 is closed and the electrolytically reduced water generated for detecting the pH value is discharged from the drain port 17 (S30).

  In S27, if the predetermined period T has not elapsed since the start of use of the electrolyzed water generating apparatus 1A (NO in S27), the control unit 15 has a pH value of electrolyzed reduced water within a range suitable for initial drinking. It is determined whether or not (S31). The range of the pH value suitable for the initial drinking is determined in advance, and is, for example, 7 to 8 in this embodiment.

  When it is determined that the pH value of the electrolytically reduced water is within the range suitable for initial drinking (YES in S31), the control unit 15 proceeds to S29 and discharges the electrolytically reduced water from the water outlet 8. On the other hand, when it is determined that the pH value of the electrolytically reduced water is outside the range suitable for initial drinking (NO in S31), the process proceeds to S30 to stop power supply to the anode power supply 41 and the cathode power supply 42, and While the valve 14 is closed, the electrolytically reduced water generated for detecting the pH value is discharged from the drain port 17.

  When the water discharge mode is not the “reduced water mode” in S24 (NO in S24), that is, when the water discharge mode is the “acidic water mode”, the control unit 15 controls the water outlet 8 as in S5 in FIG. The discharge of electrolytic acid water from is prevented (S32).

  According to the electrolyzed water generating apparatus 1 or 1A of the present embodiment having the above-described configuration, when the water discharge mode is the “reduced water mode”, the control unit 15 detects the human body when the human body detection sensor 13 detects the human body. Electrolytically reduced water is discharged from the water outlet 8. Thereby, electrolyzed reduced water is discharged from the spout 8 by a simple operation such as a hand-holding by the user, and the usability of the electrolyzed water generating device is enhanced. On the other hand, when the water discharge mode is the “acid water mode”, the control unit 15 prevents discharge of the electrolytic acid water from the water discharge port 8 even if the human body detection sensor 13 detects a human body. Thereby, it is possible to prevent the user from unintentionally discharging the electrolytic acidic water from the water outlet 8 and to prevent misuse of the electrolytic acidic water.

  As mentioned above, although the electrolyzed water generating apparatus 1 of this invention was demonstrated in detail, this invention is changed and implemented in various aspects, without being limited to said specific embodiment. That is, the electrolyzed water generating apparatus 1 includes at least an electrolysis tank 5 in which an electrolysis chamber 4 to which water to be electrolyzed is supplied, an anode power feeding body 41 and a cathode power feeding body 42 disposed to face each other, A diaphragm 43 that divides the electrolysis chamber 4 into an anode chamber 4a and a cathode chamber 4b, and electrolyzed reduced water is discharged when the water discharge mode is the reduced water mode, and electrolytic acid water is discharged when the water discharge mode is the acidic water mode. When the water discharge port 8 and the human body detection sensor 13 for detecting a human body in a non-contact manner are detected, the human body detection sensor 13 detects the human body, and the water discharge mode is the reduced water mode, electrolytic reduction is performed from the water discharge port 8. When the human body detection sensor 13 detects a human body and the water discharge mode is the acidic water mode, the controller 15 is further provided to prevent discharge of electrolytic acidic water from the water discharge port 8. That's fine.
