  A water supply channel 10 to which raw water is supplied is connected to a water purification unit 18 in which activated carbon for removing residual chlorine, turbidity, trihalomethane, or the like contained in the raw water, a hollow fiber membrane, or the like is incorporated.

  The water purification unit 18 is connected to the electrolytic cell 19 through a water passage 21, and in the water passage 21, an ultrasonic method or an electromagnetic method that detects the passage of raw water and transmits it to the control unit 3, or The flow rate sensor 22 which consists of an impeller system etc., and the addition part 23 which stores and adds electrolysis adjuvants, such as calcium glycerophosphate, to the raw | natural water passed are provided.

  The electrolytic cell 19 is divided into two chambers by a diaphragm 24. Each chamber contains an electrode 25 and an electrode 26. Usually, alkaline ion water is generated on the negative side of the electrode 25. Acidic ionic water is generated on the positive side.

  The water passage 21 is branched into two before the electrolytic cell 19 and then connected to each chamber of the electrolytic cell 19.

  Further, a drainage passage 27 for draining water from the electrolytic bath 19 and the water passage 21 is provided on the upstream side of the electrolytic bath 19, and an on-off valve 28 connected to the control unit 3 is provided in the middle of the drainage passage 27. Is arranged.

  A water discharge channel 11 is provided on the downstream side of the chamber on the electrode 25 side, and a drainage channel 12 is provided on the downstream side of the chamber on the electrode 26 side. Usually, alkaline ionized water is supplied from the water discharge channel 11 to the drainage channel 12. Acid ionic water is drained from the ground.

  The drainage channel 27 is connected in the middle of the drainage channel 12 so that the accumulated water in the electrolytic cell 19 and the water flow channel 21 can be drained from the drainage channel 12 as necessary.

  With the above configuration, the operation of the electrolyzed water generating device according to the first embodiment of the present invention will be described with reference to FIGS.

  First, when the faucet 8 is opened, raw water is supplied from the water supply channel 10 to the treatment apparatus body 2 and introduced into the water purification unit 18. In the water purification unit 18, residual bacteria and the like in the raw water are adsorbed by the activated carbon, and then general bacteria and impurities are removed by the hollow fiber membrane and the water is purified.

  The purified water subjected to the water purification process passes through the water flow path 21 and passes through the flow rate sensor 22, and at this time, the flow rate of the water flow path 21 is measured by the flow rate sensor 22 (step ST1). The measured flow rate is transmitted to the control unit 3, and the control unit 3 determines that “there is a flow rate” (Y in step ST2).

  At this time, if the user has set in advance to perform electrolysis in the operation unit 4 (Y in step ST3), the control unit 3 applies a predetermined electrolysis voltage to the electrolytic cell 19, and in the addition unit 23 glycero The purified water to which an electrolytic auxiliary agent such as calcium phosphate is added is electrolyzed in the electrolytic bath 19 to generate alkaline ion water in the chamber on the electrode 25 side and acidic ion water in the chamber on the electrode 26 side ( Step ST4).

  Here, the control unit 3 determines whether notification is necessary for the contents set in the operation unit 4 and the state of each unit of the processing apparatus main body 2 (step ST5). If the control unit 3 determines that notification is necessary (Y in step ST5), the detection means 6 detects the presence of a person (step ST6), and if the detection means 6 detects the presence of a person (step ST6) In step ST7, Y), notification is performed by the notification means 5 (step ST8).

  When the detection unit 6 does not detect the presence of a person (N in step ST7), the control unit 3 does not perform notification by the notification unit 5.

  The generated alkaline ionized water is discharged from the discharge channel 11, and the acidic ion water is discharged from the drainage channel 12.

  When the faucet 8 is closed, the supply of raw water is stopped, and when the flow rate sensor 22 detects the flow rate stop of the water passage 21 and transmits it to the control unit 3, the control unit 3 applies an electrolytic voltage to the electrolytic cell 19. Stop.

  Thereafter, the controller 3 opens the on-off valve 28 so that the accumulated water in the electrolytic cell 19 and the water passage 21 is discharged from the water drainage passage 27.

  Further, when notifying the abnormality of the processing apparatus main body 2, is it necessary to notify the control unit 3 from the contents set in the operation unit 4 after the faucet 8 is opened or the state of each part of the processing apparatus main body 2. Until the determination is made (step ST11 to step ST15), the operation is the same as described above.

  When the control unit 3 determines that notification is necessary (Y in step ST15), when the notified content is an abnormal state such as a heating state of the electrolytic cell 19 (Y in step ST16), the control unit 3 notifies the detection means 6 without detecting the presence of a person, and always reliably notifies the abnormality of the processing apparatus main body 2 (step ST19).

  On the other hand, when the content to be notified is not an abnormality of the processing apparatus body 2 such as the content set in the operation unit 4, for example, the subsequent operations are the same as those described above (from N in step ST16 to step ST19).

  As described above, according to the first embodiment of the present invention, the control unit 3 performs notification by the buzzer sound, melody, voice guide or the like from the notification unit 5 only when the detection unit 6 detects the presence of a person. Thus, it is possible to provide a water treatment apparatus in which these notification sounds are not bothersome and unnecessary power is not consumed.

  In addition, when an abnormality occurs in the processing apparatus main body 2, the control unit 3 reliably notifies the abnormality of the processing apparatus main body 2 by notifying the notification means 5 regardless of whether the detection means 6 detects the presence of a person. Therefore, a safe and easy-to-use water treatment device can be provided.

  Furthermore, by incorporating the water treatment apparatus into the sink 1, it becomes possible to greatly improve the usability in the kitchen.

  1, 2 and 6 show a water treatment apparatus according to a second embodiment of the present invention. Here, only matters different from the first embodiment will be described, and the description of the first embodiment is used for those having the same configuration, operational effects, and the like.

  The second embodiment of the present invention differs from the first embodiment in that the detection means 6 includes a distance detection unit 29 that detects the distance to the person whose presence is detected as shown in FIG. The control unit 3 can set the volume of the notification means 5.

  Based on the above differences, the operation of the electrolyzed water generating apparatus according to the second embodiment of the present invention will be described with reference to FIGS.

  Until the control unit 3 determines whether notification is necessary from the content set in the operation unit 4 or the state of each unit of the processing apparatus main body 2 after the faucet 8 is opened (step ST21 to step ST25). The operation is the same as that of the first embodiment.

  When the control unit 3 determines that notification is necessary (Y in step ST25), when the notified content is an abnormal state such as a heating state of the electrolytic cell 19 (Y in step ST26), the control unit 3 sets the volume of the notification sound of the notification means 5 to the maximum among n stages (step ST32).

  The notification means 5 notifies at the set maximum volume, and always reliably notifies about the abnormality of the processing apparatus main body 2 (step ST34).

  On the other hand, when the control unit 3 determines that the notification is necessary (Y in step ST25) and the content to be notified is not in the abnormal state as described above (N in step ST26), the control unit 3 detects the detection means. In the distance detection unit 29 provided in 6, the i-th value that is the i-th from the shorter n-step detection distance is set to 1 (step ST 27).

  Next, the control unit 3 detects the presence of a person by the detection means 6 at the detection distance (i = 1 in this case) set by the distance detection unit 29 (step ST28), and when the presence of a person is detected. (Y in step ST29), the volume of the notification means 5 is set to the i-th (in this case, i = 1) from the smallest of the n-step notification sounds (step ST31). The notification means 5 performs notification with the set volume (step ST34).

  Further, when the presence of a person is not detected in the detection means 6 (N in step ST29), the control unit 3 checks whether the value of i of the distance detection unit 29 is n, and when the value of i is not n (N in step ST30) A value obtained by adding 1 to the value of i of the distance detection unit 29 (i = 2 in this case) is set (step ST33).

  And the control part 3 detects presence of a person by the detection means 6 in the detection distance (in this case i = 2) set in the distance detection part 29 (step ST28), and when presence of a person is detected (Y of step ST29), the volume of the notification means 5 is set to the i-th (in this case, i = 2) from the smaller of the n-step notification sounds (step ST31). The notification means 5 performs notification with the set volume (step ST34).

  Furthermore, when the presence of a person is not detected by the detection means 6 (N in step ST29), the control unit 3 performs the same operation as described above (step ST30) and (step ST33). Similarly, the presence of a person is detected (step ST28) and (step ST29).

  When performing the above operation, if the value of i set in the distance detection unit 29 is n (Y in step ST30), the control unit 3 cannot detect the presence of a person in the detection unit 6. By determining, the notification by the notification means 5 is not performed.

  The generated alkaline ionized water is discharged from the discharge channel 11, and the acidic ion water is discharged from the drainage channel 12. The operation after the faucet 8 is closed is the same as the operation of the first embodiment.

  As described above, according to the second embodiment of the present invention, the control unit 3 detects the distance between the detection unit 6 and the person using the distance detection unit 29 provided in the detection unit 6 and is detected. When the distance is short, the volume of the notification means 5 is set to be low, and when the detected distance is far, the volume of the notification means 5 is set to be high and the notification is made. The notification can be made at an appropriate sound volume so that the sound volume is not bothersome.

  Further, when the detection means 6 does not detect the presence of a person, the notification means 5 does not perform notification, so the notification sound does not feel bothersome and does not consume extra power. When an abnormality occurs in 2, the abnormality of the processing apparatus main body 2 can always be notified reliably by notifying the volume of the notification means 5 at the maximum.

  In both the first and second embodiments of the present invention, alkaline ionized water is discharged from the discharge channel 11, but electrolysis is performed with the electrode 25 of the electrolytic cell 19 as positive and the electrode 26 as negative. When performed, weakly acidic ion water is discharged from the discharge channel 11 and alkaline ion water is discharged from the drain channel 12.

  Further, when electrolysis is not performed in the electrolytic bath 19, purified water is discharged and drained from both the water discharge channel 11 and the water discharge channel 12.
