  The hollow fiber membrane cartridge 16 is connected to the inflow hose 8 via a check valve 44 with a constant flow valve, and is configured to remove bacteria and impurities from the tap water flowing into the main body 2.

  The bypass switching valve 18 is configured to switch the water passage in the main body 2 based on a signal from the controller 26. Further, the bypass switching valve 18 is connected to the hollow fiber membrane cartridge 16 via the upstream water passage 28a, to the activated carbon cartridge 20 via the upstream water passage 28b, and to the calcium supply unit 22 via the bypass water passage 32. Each is connected to a drain valve 42 via a drain passage 38.

  In the normal operation mode in which alkaline ionized water or purified water is discharged, the bypass switching valve 18 is set at a normal position for connecting the upstream water passage 28a from the hollow fiber membrane cartridge 16 to the upstream water passage 28b. Further, the bypass switching valve 18 is switched to a cleaning position that connects the upstream water passage 28 a and the bypass water passage 32 in the water passage cleaning mode in which the water passage is sterilized and cleaned. Furthermore, the bypass switching valve 18, when discharging the accumulated water in the main body 2 at the time of water stoppage, a position where the upstream side water passage 28 a and the drainage water passage 38 are connected, and the bypass water passage 32 and the water drainage passage. The position is switched to the position where the water channel 38 is connected.

  The activated carbon cartridge 20 is configured to adsorb and remove residual chlorine and trihalomethane in the water flowing in from the hollow fiber membrane cartridge 16 via the bypass switching valve 18 and the upstream water passage 28b. The purified water purified by the activated carbon cartridge 20 is configured to flow into the check valve 46 through the downstream water passage 30.

  The calcium supply unit 22 adds calcium ions such as calcium glycerophosphate and calcium lactate to the purified water that flows out from the activated carbon cartridge 20 and flows in through the downstream water passage 30 and the check valve 46, thereby increasing the electrical conductivity of the water. It is configured to be high. Further, the water that has not passed through the activated carbon cartridge 20 and has passed through the bypass water passage 32 is also configured to flow into the calcium supply unit 22. That is, the bypass water passage 32 bypassing the activated carbon cartridge 20 joins again upstream of the calcium supply unit 22. Further, the calcium supply unit 22 is provided with a calcium supply port (not shown) for supplying calcium added by the user. The main body 2 also includes a sensor (not shown) that is an open detection means for detecting the opening and closing of the cap 2a (FIG. 1) that covers the calcium replenishing port (not shown). Is sent to the controller 26.

  The electrolytic cell 24 is configured to generate an alkaline ionized water by causing an electric field to act on water that has flowed from the calcium supply unit 22 through the electrolytic cell inflow passage 34 and electrolyzing the water. That is, a pair of electrodes (not shown) are disposed inside the electrolytic cell 24, and an electric field is applied to the flowing water by applying a DC voltage between these electrodes to electrolyze the water. It is configured as follows. When a DC voltage is applied to the electrode, alkaline water containing a large amount of cations such as sodium ions and calcium ions is generated on the cathode side, and acidic water containing a large amount of anions such as chloride ions is formed on the anode side. Generated. The alkaline alkaline ionized water generated in the electrolytic bath 24 is discharged from the water discharge port of the water discharge head 4 through the alkali water passage 36, the outflow hose 10, and the water discharge head 4. On the other hand, the acidic water generated in the electrolytic cell 24 is discharged to the sink via the acidic water passage 40 and the drain hose 14.

  The controller 26 is configured to control the electric field generated by the bypass switching valve 18 and the electrode in the electrolytic cell 24 based on the operation of the operation display unit 12 by the user. The controller 26 is configured to reverse the direction of the electric field applied to the water in the electrolytic cell 24 during operation in the water channel cleaning mode, or to cut the applied electric field without applying a voltage to the electrodes. Yes. When the direction of the electric field applied to the water in the electrolytic cell 24 is reversed, the acidic water flows into the alkaline water passage 36 connected to the electrolytic cell 24 and is discharged through the outflow hose 10 and the water discharge head 4. The In addition, when water containing a large amount of residual chlorine that has not passed through the activated carbon cartridge 20 flows into the electrolytic cell 24, hypochlorous acid having strong sterilizing power is generated by applying an electric field to the water. The When the direction of the electric field is reversed during operation in the water passage cleaning mode, water containing a large amount of hypochlorous acid is discharged through the alkali water passage 36, the outflow hose 10, and the water discharge head 4.

Next, with reference to FIG.3 and FIG.4, the structure of the connection part of the water discharging head 4, the inflow hose 8, and the outflow hose 10 is demonstrated.
As shown in FIG. 3, the inflow hose 8 and the outflow hose 10 connected to the water discharge head 4 are coupled by a hose coupling portion 48, and two hoses are connected by connecting the hose coupling portion 48 to the water ejection head 4. It can be simultaneously connected to the rear part of the water discharge head 4. Two limit switches 4b, which are open detection means, are provided in the joint portion of the water discharge head 4 with the hose joint portion 48 so that the connection and removal of the inflow hose 8 and the outflow hose 10 can be detected. . That is, when the hose coupling portion 48 is connected to the water discharge head 4, the engagement claws 48 a provided on both side surfaces thereof press the limit switches 4 b.

  As shown in FIG. 4, the water discharge head 4 includes two limit switches 4b, a detection unit 50a, a circuit 50b for driving the detection unit, a battery 50c, and a transmission / reception unit 50d. When the hose coupling part 48 is connected to the water discharge head 4 and each limit switch 4b is pressed, each limit switch 4b is turned on, and this is detected by the detection part 50a. The signal detected by the detection unit 50a is wirelessly transmitted to the main body unit 2 by the transmission / reception unit 50d. On the other hand, the main body unit 2 has a built-in main body transmission / reception unit 50e that receives a signal transmitted from the transmission / reception unit 50d of the water discharge head 4 so as to receive a signal indicating whether or not the hose coupling unit 48 is connected. It is configured. The signal received by the main body transmission / reception unit 50e is sent to the controller 26. Thereby, the controller 26 can detect that the hose coupling portion 48 is removed and a part of the water passage is opened.

Next, the structure of the bypass switching valve 18 will be described with reference to FIG.
FIG. 5 is a cross-sectional view schematically showing the structure of the bypass switching valve 18. As shown in FIG. 5, the bypass switching valve 18 connects the four water passages of the upstream water passage 28a, the upstream water passage 28b, the bypass water passage 32, and the drain water passage 38 in a cross shape. It is configured. Furthermore, the bypass switching valve 18 includes a valve body 18a that is slidably disposed in the water passage in accordance with a control signal from the controller 26. The valve body 18a is configured to close the bypass water passage 32 when moved to the left side in FIG. 5 and close the upstream water passage 28b when moved to the right side. That is, when the controller 26 sends a control signal for switching the bypass switching valve 18 to the normal position, the valve body 18a is moved to the left side in FIG. 5, and thereby, the upstream side water passage 28a, the upstream side water passage 28b, and the water drainage. The water passages 38 are in communication with each other. Conversely, when the bypass switching valve 18 is switched to the cleaning position, the valve element 18a is moved to the right side in FIG. 5, whereby the upstream water passage 28a, the bypass water passage 32, and the drain water passage 38 communicate with each other. It becomes a state to do.

Next, the structure of the drain valve 42 will be described with reference to FIG.
FIG. 6 is a cross-sectional view showing the structure of the water drain valve 42. The drain valve 42 is arranged so that the upper side in FIG. 6 is connected to the drain drain passage 38 and the lower side communicates with the drain hose 14. As shown in FIG. 6, the drain valve 42 includes a valve seat portion 42a, a ball valve body 42b seated on the valve seat portion 42a, a sliding member 42c that pulls the ball valve body 42b away from the valve seat 42a, An urging spring 42d for urging the sliding member 42c.

  The valve seat portion 42a is formed of an annular member, and a mortar-shaped valve seat is provided on the inner periphery thereof. When the spherical ball valve body 42b is seated on the valve seat, the water passage is closed. The sliding member 42c is formed of an annular sliding portion slidably disposed inside the drain valve 42 and a push rod portion supported at the center of the sliding portion. When the member 42c is moved upward in FIG. 6, the push rod portion is configured to push the ball valve body 42b and pull it away from the valve seat portion 42a. The biasing spring 42d is disposed inside the drain valve 42 so as to bias the sliding member 42c upward in FIG.

  When the faucet 6 is discharged, the urging spring 42d is compressed by the pressure of water passing through the hollow fiber membrane cartridge 16 and passing through the bypass switching valve 18 and the drainage water passage 38 to the drain valve 42. The valve seat portion 42a is closed by the ball valve body 42b. On the other hand, when the water faucet 6 is in a water-stopped state, the biasing spring 42d is configured to extend when the pressure of water acting on the ball valve body 42b decreases. As a result, when the water is stopped, the ball valve body 42b is pulled away from the valve seat 42a, and the drain valve 42 is automatically opened.

  In the present embodiment, the drain valve 42 is disposed below the downstream water passage 30, the upstream water passage 28 b, the bypass water passage 32, and the calcium supply unit 22. For this reason, when these portions and the drain valve 42 communicate with each other in the water stop state, the water staying inside flows downward due to gravity and is discharged through the drain valve 42. In the present embodiment, since the activated carbon cartridge 20 and the electrolytic cell 24 extend below the drain valve 42, the water inside them is not discharged from the drain valve 42 by gravity. Absent.

Next, with reference to FIG. 7 thru | or FIG. 12, the effect | action of the alkaline ionized water generator 1 by embodiment of this invention is demonstrated.
FIG. 7 is an enlarged view of the operation display unit 12 provided in the main body unit 2. Moreover, FIG. 8 thru | or FIG. 12 is a flowchart which shows the effect | action of the alkaline ionized water generator 1 by this embodiment.

  As shown in FIG. 7, the operation display unit 12 includes four push button switches SW1 to SW4, LEDs 1 to LED4 indicating that these push button switches have been pressed, and the alkaline ionized water generator 1 respectively. An LED 5 indicating that the water channel cleaning mode is in operation and a liquid crystal display 12 a for displaying the operation state of the alkaline ionized water generator 1 are provided. The push button switch SW1 is a switch for discharging strongly alkaline ionized water, and the pushbutton switch SW2 is a switch for discharging weakly alkaline ionized water. Moreover, pushbutton switch SW3 is a switch for discharging the neutral purified water which is not electrolyzed. Further, the push button switch SW4 is a switch for executing the operation in the water passage cleaning mode.

  FIG. 8 is a flowchart of a main routine showing the operation of the alkaline ionized water generator 1. First, in step S1 of FIG. 8, the controller 26 determines whether or not the push button switch of the operation display unit 12 has been pressed. If no push button switch is pressed, the process proceeds to step S2, and if any push button switch is pressed, the process proceeds to step S7.

  In step S7, the process branches to various processing routines according to the operated push button switch. If any of the push button switches SW1 to SW3 is operated, the process proceeds to step S8, and if the push button switch SW4 is pressed, the process proceeds to step S9.

  In step S8, the controller 26 executes the normal operation mode. In the normal operation mode, the controller 26 first sends a signal to the bypass switching valve 18 and switches it to a normal position where the upstream water passage 28a and the upstream water passage 28b communicate with each other. Furthermore, the controller 26 controls the voltage applied to the electrode of the electrolytic cell 24 according to the pushed pushbutton switch. First, when the push button switch SW1 is pressed, the controller 26 applies a high voltage between the electrodes of the electrolytic cell 24 in order to generate strong alkaline ionized water. At this time, the LED 1 above the push button switch SW1 is turned on. In this state, when the user operates the faucet 6 to discharge water, the tap water discharged from the faucet 6 passes through the inflow hose 8 to the check valve 44 with a constant flow valve in the main body 2. It flows in and reaches the hollow fiber membrane cartridge 16.

  In the hollow fiber membrane cartridge 16, impurities and the like in tap water are removed. The water that flows out of the hollow fiber membrane cartridge 16 further flows into the activated carbon cartridge 20 through the upstream water passage 28a, the bypass switching valve 18, and the upstream water passage 28b. As described above, the bypass switching valve 18 is also configured to communicate with the drainage water passage 38. However, when the faucet 6 is in a water discharge state, the drainage valve 18 is caused by the pressure of water flowing through the water passage. Since 42 is closed, water does not flow to the water passage 38 side in the water discharge state. In the activated carbon cartridge 20, residual chlorine in tap water is removed. The water flowing out from the activated carbon cartridge 20 further flows into the calcium supply unit 22 through the check valve 46. In the calcium supply unit 22, calcium is added to the inflowed water, and the water that has passed through the calcium supply unit 22 flows into the electrolytic cell 24. In the electrolytic cell 24, an electric field is applied to the inflowed water by the built-in electrodes, and the water is electrolyzed.

  In the electrolytic bath 24, alkaline ionized water generated by electrolysis flows into the outflow hose 10 through the alkali water passage 36 and is discharged from the water discharge port of the water discharge head 4. On the other hand, the acidic water produced together with the alkaline ionized water in the electrolytic cell is discharged through the acidic water passage 40 and the drainage hose 14.

  On the other hand, when the push button switch SW2 is pressed, the controller 26 applies a lower voltage between the electrodes of the electrolytic cell 24 than in the case of strong alkaline ionized water in order to generate weakly alkaline ionized water. At this time, the LED 2 above the push button switch SW2 is turned on. In this case, the action of generating weak alkaline ionized water is the same as that in the case of strong alkaline ionized water except for the voltage applied between the electrodes, and thus the description thereof is omitted.

  Further, when the push button switch SW3 is pressed, the controller 26 turns off the applied voltage between the electrodes of the electrolytic cell 24 in order to generate neutral purified water. At this time, the LED 3 above the push button switch SW3 is turned on. In this case, the electrolysis in the electrolytic cell 24 is not performed, and the purified water purified by the hollow fiber membrane cartridge 16 and the activated carbon cartridge 20 is discharged from the water discharge port of the water discharge head 4 as it is.

  When the push button switch SW4 is pressed, the process proceeds to step S9, and the operation in the water passage cleaning mode is performed by the switch operation. The process in step S9 will be described in detail later with reference to FIG.

  on the other hand. If it is determined in step S1 of FIG. 8 that the push button switch of the operation display unit 12 is not pressed, the process proceeds to step S2. In step S2, it is determined whether or not the hose coupling portion 48 has been removed from the water discharge head 4, or whether or not the cap 2a has been removed. In any of these cases, since a part of the water passage of the alkaline ionized water generator 1 is opened, there is a possibility that various bacteria have entered the water passage. For this reason, when a part of water channel is opened, it progresses to Step S10 and operation of a water channel washing mode by opening of a water channel is performed. The process in step S10 will be described in detail later with reference to FIG.

  If it is determined in step S2 of FIG. 8 that the water passage is not open, the process proceeds to step S3, and in step S3, it is determined whether or not the water tap 6 is discharged by the user. Is done. When it is in the water stop state, the process of step S3 is repeated, and when it is in the water discharge state, the process proceeds to step S4.

  In step S4, it is determined whether or not a predetermined period or more has elapsed from the previous water discharge to the current water discharge. If a long time has elapsed between the previous water discharge and the current water discharge, since the germs may have propagated in the water channel while the water is stopped, the process proceeds to step S11. In step S11, the automatic water channel cleaning mode is executed. The process in step S11 will be described in detail later with reference to FIG.

  Next, in step S5, the normal operation mode currently set is executed by operating the push button switches SW1 to SW3. Since the process in step S5 is the same as the process in step S8 described above, description thereof is omitted.

  Furthermore, in step S6, the draining process performed when the water tap 6 is made into a water stop state is performed. The process in step S6 will be described in detail later with reference to FIG.

  Next, the process in step S9 (FIG. 8) will be described. The process in step S9 is a process executed when the push button switch SW4 is pressed, and the process of the flowchart shown in FIG. 9 is executed as a subroutine in order to operate the water passage cleaning mode by the switch operation. .

  First, in step S101 of FIG. 9, a limit switch 4b provided on the water discharge head 4 that detects attachment / detachment of the hose coupling portion 48 and a sensor (not shown) that detects attachment / detachment of the cap 2a of the main body 2 are released. Is done. Accordingly, the detection signals of the limit switch 4b and the cap 2a attachment / detachment sensor (not shown) are ignored by the controller 26 during the processing of the subroutine of FIG.

  Next, in step S102, the display of the operation display unit 12 is switched. That is, the LED 4 of the operation display unit 12 is lit in red to indicate that the push button switch SW4 has been pressed, and the LED 5 is flashed in red to notify that the water channel cleaning mode operation has started. In addition, the message “Attach the hose and calcium cap and let water through. We will wash the strong pipes” is displayed on the liquid crystal display 12a.

  Next, in step S103, the user sets the faucet 6 to a water discharge state according to a message on the liquid crystal display 12a, and determines whether tap water is being passed through the main body 2 or not. If water flow is confirmed, the process proceeds to step S104. If water is not passed, the process of step S103 is repeated.

Next, in step S104, a timer that counts the cleaning processing time starts integration.
Furthermore, in step S105, the LED 5 of the operation display unit 12 is turned on in red, and the display on the liquid crystal display 12a is changed to “during strong cleaning”. Furthermore, the controller 26 sends a signal to the bypass switching valve 18 and switches it to a cleaning position where the upstream water passage 28a and the bypass water passage 32 communicate with each other. As a result, the tap water flowing out from the hollow fiber membrane cartridge 16 bypasses the activated carbon cartridge 20 and flows directly into the calcium supply unit 22. At this time, since the drain valve 42 is closed by the pressure of the water that has flowed in, water does not flow from the bypass switching valve 18 toward the drain water passage 38. In addition, the controller 26 sounds a buzzer (not shown) built in the main body 2 to notify the user by voice that the water discharged from the water discharge head 4 is not suitable for drinking. Further, information indicating that the bypass switching valve 18 is switched to the cleaning position is stored in a memory (not shown) of the controller 26.

  Subsequently, in step S106, the controller 26 sends a signal to the electrolytic cell 24, and applies a voltage having a polarity opposite to that during normal alkaline ionized water generation to the electrode built in the electrolytic cell 24. As a result, an electric field in the direction opposite to that during the generation of alkaline ionized water is applied to the water flowing into the electrolytic cell 24. Further, since the water flowing into the electrolytic cell 24 bypasses the activated carbon cartridge 20, a large amount of chlorine component remains, and when an electric field is applied in the electrolytic cell 24, hypochlorous acid having a strong sterilizing power. An acid is produced. Thereby, acidic water containing hypochlorous acid flows into the alkaline water passage 36 extending from the electrolytic cell 24. Acidic water containing hypochlorous acid that has flowed out of the electrolytic cell 24 is discharged from the water outlet through the alkali water passage 36, the outflow hose 10, and the water discharge head 4, and these water passages are sterilized and washed strongly.

  Next, in step S107, it is determined whether the water flow state to the main body 2 is continued. When the water flow state continues, the process proceeds to step S108, and when the user places the water tap 6 in the water stop state during the water channel cleaning mode, the process proceeds to step S113.

  Further, in step S108, it is determined whether or not a predetermined pre-cleaning time has elapsed. That is, it is determined whether or not the timer that has started counting in step S104 has reached a predetermined pre-cleaning time. When the predetermined pre-cleaning time has elapsed, the process proceeds to step S109, and when the pre-cleaning time has not elapsed, the process returns to step S107. In the present embodiment, the cleaning is performed in a state where the bypass switching valve 18 is switched to the cleaning position for 20 seconds that is the pre-cleaning time.

  In step S109, the controller 26 sends a signal to the bypass switching valve 18 and switches it to the normal position where the upstream water passage 28a and the upstream water passage 28b communicate. As a result, the tap water flowing out from the hollow fiber membrane cartridge 16 flows into the activated carbon cartridge 20. Information that the bypass switching valve 18 is switched to the normal position is stored in a memory (not shown) of the controller 26. Further, the controller 26 sends a signal to the electrolytic cell 24 to turn off the voltage applied to the electrode built in the electrolytic cell 24 and cut off the electric field acting on the water. Thus, the purified water purified by the activated carbon cartridge 20 is discharged without being electrolyzed in the electrolytic cell 24. The purified water discharged from the electrolytic cell 24 is discharged from the water outlet through the alkali water passage 36, the outflow hose 10, and the water discharge head 4, and the acidic water containing hypochlorous acid adhering to these water passages is washed away. .

  Next, in step S110, it is determined whether or not the water flow state to the main body 2 is continued. When the water flow state continues, the process proceeds to step S111, and when the user sets the water tap 6 in the water stop state during the water channel cleaning mode, the process proceeds to step S113.

  Further, in step S111, it is determined whether or not a predetermined post-cleaning time has elapsed. That is, it is determined whether or not the post-cleaning started in step S109 has reached a predetermined post-cleaning time. If the predetermined post-cleaning time has elapsed, the process proceeds to step S112. If the post-cleaning time has not elapsed, the process returns to step S110. In the present embodiment, it is determined in step S111 whether or not 30 seconds have elapsed since the start of timer integration in step S104. That is, in the present embodiment, after the pre-cleaning time of 20 seconds elapses, cleaning is performed with the bypass switching valve 18 switched to the normal position for 10 seconds, which is the post-cleaning time.

  Further, in step S112, the LED 5 of the operation display unit 12 is turned on in blue, and the display on the liquid crystal display 12a is changed to “cleaning completed”. Moreover, the controller 26 stops the ringing of a buzzer (not shown), and notifies the user that the operation in the water passage cleaning mode has ended. Further, the controller 26 turns off the LED 4, and returns the operation display unit 12 to the state set before the push button switch SW4 is operated for cleaning, and the process of the flowchart shown in FIG. . For example, when weak alkaline ionized water is selected before the push button switch SW4 is pressed, the controller 26 lights the LED 2 in blue and controls each part so that the weak alkaline ionized water is discharged. .

  Note that the controller 26 does not accept the operation of the push button switches SW1 to SW4 for the entire cleaning time after the process of step S102 is completed and until the process of step S112 is completed. Even if the switch is operated, the operation is ignored.

Next, the process after step S113 is demonstrated.
The processing after step S113 is processing when it is determined in step S107 or S110 that the user has set the faucet 6 to the water stop state during the operation in the water passage cleaning mode.

  First, in step S113, the controller 26 stops a buzzer (not shown) that is ringing. Further, the controller 26 switches the LED 5 that has been lit in red to blink in red, and displays “cleaning incomplete” on the liquid crystal display 12a. Next, in step S114, a water draining process (FIG. 10) when the faucet 6 is in a water stop state is executed.

  When the process of step S114 ends, the process returns to step S103. As described above, in step S103, it is determined whether or not the faucet 6 is opened. If not, the process is repeated. When the faucet 6 is opened again, the processing after step S104 is executed, and the suspended cleaning processing is executed from the beginning.

  Next, with reference to FIG. 10, the water draining process executed in step S114 of FIG. 9 will be described. FIG. 10 is a flowchart of the water draining process that is executed when the water faucet 6 is in a water stop state.

  First, in step S201 of FIG. 10, it is determined whether or not the faucet 6 is in a water stop state. If the water stop state is set, the process proceeds to step S202. If the water discharge state is set, the process of step S201 is repeated.

In step S202, a timer that counts the time for draining starts accumulation.
Further, in step S203, it is determined whether the bypass switching valve 18 is in the normal position or the cleaning position. That is, in step S203, the state of the bypass switching valve 18 stored in the memory of the controller 26 is determined. If the bypass switching valve 18 is in the normal position, the process proceeds to step S204. If the bypass switching valve 18 is in the cleaning position, step S208 is performed. Proceed to For example, when step S203 is executed from step S110 of FIG. 9 through step S113, the fact that the bypass switching valve 18 is in the normal position is stored in the memory, and thus the process proceeds to step S204.

  Next, in step S204, it is determined whether or not the accumulated time of the timer started in step S202 has reached a predetermined drainage time. If the predetermined drainage time has not been reached, the process of step S204 is repeated. In the present embodiment, the process of step S204 is repeated for 5 seconds after the timer integration is started. During this predetermined drainage time, since the faucet 6 is in a water-stopped state and not passed through the main body 2, the ball valve body 42b of the drain valve 42 is pushed up by the biasing spring 42d, The drain valve 42 is opened. The bypass switching valve 18 is switched to a normal position where the upstream water passage 28a and the upstream water passage 28b communicate with each other, that is, so that the water drain valve 42 and the activated carbon cartridge 20 communicate with each other. For this reason, the water staying in the upstream water passage 28b located at a position higher than the water drain valve 42 is, by gravity, within a predetermined water drain time, by the bypass switching valve 18, the water drain water passage 38, and The water is discharged from the drain hose 14 through the drain valve 42. Further, since the downstream water passage 30 is also at a higher position than the drain valve 42, the water remaining in the downstream water passage 30 passes through the activated carbon cartridge 20 and is similarly discharged by gravity.

  Further, in the present embodiment, since the activated carbon cartridge 20 and the electrolytic cell 24 are located at a position lower than the drain valve 42, the water inside these remains retained. However, in the present embodiment, the activated carbon cartridge 20 is provided with a heating means (not shown) for heating the activated carbon to boil the internal water. Can be kept in. Moreover, since the inside of the electrolytic cell 24 is sterilized by water containing acidic water or hypochlorous acid, it can be kept clean even if water stays inside.

When the predetermined drainage time has elapsed, the process proceeds to step S205. In step S205, the bypass switching valve 18 is switched to the cleaning position.
Further, in step S206, it is determined whether or not a predetermined drainage time has elapsed. If the predetermined drainage time has not elapsed, the process of step S206 is repeated. In the present embodiment, the process of step S206 is repeated for 5 seconds after the process of step S205 is executed, that is, until the accumulated time of the timer started in step S202 reaches 10 seconds.

  At the cleaning position of the bypass switching valve 18, the bypass water passage 32 and the upstream water passage 28 a are communicated, that is, the bypass water passage 32 and the drain valve 42 are communicated. Thereby, the water staying in the bypass water passage 32 at a position higher than the water drain valve 42 is within the predetermined water drain time for the bypass switching valve 18, the water drain water passage 38, and the water drain valve. 42 is discharged from the drainage hose 14. Further, the water staying in the calcium supply unit 22 communicating with the bypass water passage 32 is also discharged from the drain hose 14 through the drain valve 42 in the same manner.

  Next, when the accumulated time of the timer reaches 10 seconds, the process proceeds to step S207. In step S207, the controller 26 returns the bypass switching valve 18 to the normal position, and ends the process of the flowchart of FIG.

  On the other hand, when the bypass switching valve 18 is at the cleaning position in step S203, the process proceeds to step S208. In step S208, the process is repeated until a predetermined drainage time elapses. During this time, since the bypass switching valve 18 is in the cleaning position, the water staying in the bypass water passage 32 is discharged as in step S206.

  Furthermore, when a predetermined drainage time has elapsed, the process of step S209 is executed. In step S209, the controller 26 switches the bypass switching valve 18 to the normal position. Next, in step S209, the process is repeated until a predetermined drainage time has elapsed. During this time, since the bypass switching valve 18 is in the normal position, the water remaining in the upstream side water passage 28b, the downstream side water passage 30 and the activated carbon cartridge 20 is discharged, as in step S204.

  Next, when the accumulated time of the timer reaches 10 seconds, the process proceeds to step S211. In step S211, the controller 26 returns the bypass switching valve 18 to the cleaning position, and ends the process of the flowchart of FIG.

  Next, the process executed in step S10 in FIG. 8 will be described with reference to FIG. FIG. 11 is a flowchart of the operation in the water channel cleaning mode that is executed when the water channel is opened.

  First, in step S301 of FIG. 11, the display of the operation display unit 12 is switched. That is, the LED 5 blinks red to notify that the water channel cleaning mode operation has started. In addition, the message “Attach the hose and calcium cap and let water through. We will wash the strong pipes” is displayed on the liquid crystal display 12a.

  Next, in step S <b> 302, the user sets the faucet 6 to the water discharge state according to the message on the liquid crystal display 12 a, and determines whether tap water is being passed through the main body 2. When the water flow is confirmed, the process proceeds to step S303, and when the water flow is not performed, the process of step S302 is repeated.

Next, in step S303, a timer that counts the cleaning processing time starts integration.
Furthermore, in step S304, the LED 5 of the operation display unit 12 is turned on in red, and the display on the liquid crystal display 12a is changed to “during strong cleaning”. Furthermore, the controller 26 sends a signal to the bypass switching valve 18 and switches it to a cleaning position where the upstream water passage 28a and the bypass water passage 32 communicate with each other. As a result, the tap water flowing out from the hollow fiber membrane cartridge 16 bypasses the activated carbon cartridge 20 and flows directly into the calcium supply unit 22. In addition, the controller 26 sounds a buzzer (not shown) built in the main body 2 to notify the user by voice that the water discharged from the water discharge head 4 is not suitable for drinking. Further, information indicating that the bypass switching valve 18 is switched to the cleaning position is stored in a memory (not shown) of the controller 26.

  Subsequently, in step S <b> 305, the controller 26 sends a signal to the electrolytic cell 24 to cut off the voltage applied to the electrode built in the electrolytic cell 24. Thereby, an electric field does not act on the water flowing into the electrolytic cell 24, and the water flows out from the electrolytic cell 24 without being electrolyzed. Further, since the water flowing into the electrolytic cell 24 bypasses the activated carbon cartridge 20, a large amount of chlorine component remains and has sterilizing power. Thereby, water containing a chlorine component flows into the alkali water passage 36 extending from the electrolytic cell 24. The water containing the chlorine component flowing out from the electrolytic cell 24 is discharged from the water outlet through the alkali water passage 36, the outflow hose 10, and the water discharge head 4, and sterilizes and cleans these water passages.

  Next, in step S306, it is determined whether or not the water flow state to the main body 2 is continued. When the water flow state continues, the process proceeds to step S307, and when the user sets the water tap 6 in the water stop state during the water channel cleaning mode, the process proceeds to step S312.

  Further, in step S307, it is determined whether or not a predetermined pre-cleaning time has elapsed. That is, it is determined whether or not the timer that has started counting in step S303 has reached a predetermined pre-cleaning time. If the predetermined pre-cleaning time has elapsed, the process proceeds to step S308, and if the pre-cleaning time has not elapsed, the process returns to step S306. In the present embodiment, the cleaning is performed in a state where the bypass switching valve 18 is switched to the cleaning position for 20 seconds that is the pre-cleaning time.

  In step S308, the controller 26 sends a signal to the bypass switching valve 18 and switches it to the normal position where the upstream water passage 28a and the upstream water passage 28b communicate. As a result, the tap water flowing out from the hollow fiber membrane cartridge 16 flows into the activated carbon cartridge 20. Information that the bypass switching valve 18 is switched to the normal position is stored in a memory (not shown) of the controller 26. The purified water purified by the activated carbon cartridge 20 passes through the electrolytic cell 24, is discharged from the water outlet through the alkali water passage 36, the outflow hose 10, and the water discharge head 4, and contains chlorine components adhering to these water passages. Water is washed away.

  Next, in step S309, it is determined whether or not the water flow state to the main body 2 is continued. When the water flow state continues, the process proceeds to step S310, and when the user sets the water tap 6 in the water stop state during the water channel cleaning mode, the process proceeds to step S312.

  Further, in step S310, it is determined whether or not a predetermined post-cleaning time has elapsed. That is, it is determined whether or not the post-cleaning started in step S308 has reached a predetermined post-cleaning time. If the predetermined post-cleaning time has elapsed, the process proceeds to step S311. If the post-cleaning time has not elapsed, the process returns to step S309. In the present embodiment, it is determined in step S310 whether 30 seconds have elapsed since the start of timer integration in step S303. That is, in the present embodiment, after the pre-cleaning time of 20 seconds elapses, cleaning is performed with the bypass switching valve 18 switched to the normal position for 10 seconds, which is the post-cleaning time.

  Further, in step S311, the LED 5 of the operation display unit 12 is lit in blue, and the display on the liquid crystal display 12a is changed to “cleaning complete”. Further, the controller 26 stops the ringing of a buzzer (not shown), notifies the user that the operation in the water channel cleaning mode has ended, and ends the processing of the flowchart shown in FIG.

  Note that the controller 26 does not accept the operation of the push button switches SW1 to SW4 for the entire cleaning time after the process of step S301 is completed and until the process of step S310 is completed. Even if the switch is operated, the operation is ignored.

Next, the process after step S312 is demonstrated.
The processing after step S312 is processing when it is determined in step S306 or S309 that the user has turned the water tap 6 in the water stop state during the operation in the water passage cleaning mode.

  First, in step S312, the controller 26 stops a ringing buzzer (not shown). Further, the controller 26 switches the LED 5 that has been lit in red to blink in red, and displays “cleaning incomplete” on the liquid crystal display 12a. Next, in step S313, the water draining process shown in FIG. 10 when the faucet 6 is stopped is executed.

  When the process of step S313 ends, the process returns to step S302. As described above, in step S302, it is determined whether or not the faucet 6 is opened. If not, the process is repeated. When the faucet 6 is opened again, the processes after step S303 are executed, and the interrupted cleaning process is executed from the beginning.

  Next, with reference to FIG. 12, the operation in the automatic water channel cleaning mode executed in step S11 of FIG. 8 will be described. FIG. 12 is a flowchart of the automatic water channel cleaning mode executed every predetermined period.

  First, in step S401 in FIG. 12, it is determined whether or not the faucet 6 is in a water discharge state and tap water is passed through the main body 2. When the water flow is confirmed, the process proceeds to step S402, and when the water flow is not performed, the process of step S401 is repeated.

Next, in step S402, a timer that counts the cleaning processing time starts integration.
Further, in step S403, the LED 5 of the operation display unit 12 is lit in red, and the display on the liquid crystal display 12a is changed to “being washed”. Furthermore, the controller 26 sends a signal to the bypass switching valve 18 and switches it to a cleaning position where the upstream water passage 28a and the bypass water passage 32 communicate with each other. As a result, the tap water flowing out from the hollow fiber membrane cartridge 16 bypasses the activated carbon cartridge 20 and flows directly into the calcium supply unit 22. In addition, the controller 26 sounds a buzzer (not shown) built in the main body 2 to notify the user by voice that the water discharged from the water discharge head 4 is not suitable for drinking. Further, information indicating that the bypass switching valve 18 is switched to the cleaning position is stored in a memory (not shown) of the controller 26.

  Subsequently, in step S <b> 404, the controller 26 sends a signal to the electrolytic cell 24 and cuts off the voltage applied to the electrode built in the electrolytic cell 24. Thereby, an electric field does not act on the water flowing into the electrolytic cell 24, and the water flows out from the electrolytic cell 24 without being electrolyzed. Further, since the water flowing into the electrolytic cell 24 bypasses the activated carbon cartridge 20, a large amount of chlorine component remains and has sterilizing power. Thereby, water containing a chlorine component flows into the alkali water passage 36 extending from the electrolytic cell 24. The water containing the chlorine component flowing out from the electrolytic cell 24 is discharged from the water outlet through the alkali water passage 36, the outflow hose 10, and the water discharge head 4, and sterilizes and cleans these water passages.

  Next, in step S405, it is determined whether the water flow state to the main body 2 is continued. When the water flow state continues, the process proceeds to step S406, and when the user sets the water tap 6 in the water stop state during the water channel cleaning mode, the process proceeds to step S411.

  Further, in step S406, it is determined whether or not a predetermined pre-cleaning time has elapsed. That is, it is determined whether or not the timer that has started counting in step S402 has reached a predetermined pre-cleaning time. If the predetermined pre-cleaning time has elapsed, the process proceeds to step S407, and if the pre-cleaning time has not elapsed, the process returns to step S405. In the present embodiment, the cleaning is performed in a state where the bypass switching valve 18 is switched to the cleaning position for 20 seconds that is the pre-cleaning time.

  In step S407, the controller 26 sends a signal to the bypass switching valve 18, and switches it to the normal position where the upstream water passage 28a and the upstream water passage 28b communicate. As a result, the tap water flowing out from the hollow fiber membrane cartridge 16 flows into the activated carbon cartridge 20. Information that the bypass switching valve 18 is switched to the normal position is stored in a memory (not shown) of the controller 26. The purified water purified by the activated carbon cartridge 20 passes through the electrolytic cell 24, is discharged from the water outlet through the alkali water passage 36, the outflow hose 10, and the water discharge head 4, and contains chlorine components adhering to these water passages. Water is washed away.

  Next, in step S408, it is determined whether the water flow state to the main body unit 2 is continued. When the water flow state continues, the process proceeds to step S409, and when the user sets the water tap 6 in the water stop state during the water channel cleaning mode, the process proceeds to step S411.

  Further, in step S409, it is determined whether or not a predetermined post-cleaning time has elapsed. That is, it is determined whether or not the post-cleaning started in step S407 has reached a predetermined post-cleaning time. If the predetermined post-cleaning time has elapsed, the process proceeds to step S410. If the post-cleaning time has not elapsed, the process returns to step S408. In this embodiment, it is determined in step S409 whether or not 30 seconds have elapsed since the start of timer integration in step S402. That is, in the present embodiment, after the pre-cleaning time of 20 seconds elapses, cleaning is performed with the bypass switching valve 18 switched to the normal position for 10 seconds, which is the post-cleaning time.

  Further, in step S410, the LED 5 of the operation display unit 12 is lit in blue, and the display on the liquid crystal display 12a is changed to “cleaning complete”. Further, the controller 26 stops the ringing of a buzzer (not shown), notifies the user that the operation in the water passage cleaning mode has ended, and ends the processing of the flowchart shown in FIG.

  Note that the controller 26 does not accept the operation of the push button switches SW1 to SW4 for the entire cleaning time after the process of step S401 is completed and until the process of step S409 is completed. Even if the switch is operated, the operation is ignored.

Next, the process after step S411 is demonstrated.
The processing after step S411 is processing when it is determined in step S405 or S408 that the user has set the water tap 6 to the water stop state during the operation in the water passage cleaning mode.

First, in step S411, the controller 26 stops a ringing buzzer (not shown). Further, the controller 26 switches the LED 5 that has been lit in red to blink in red, and displays “cleaning incomplete” on the liquid crystal display 12a. Next, in step S412, the water draining process shown in FIG. 10 when the faucet 6 is in a water stop state is executed.
When the process of step S412 ends, the process returns to step S401. As described above, in step S401, it is determined whether or not the faucet 6 is opened. If not, the process is repeated. When the faucet 6 is opened again, the processing after step S402 is executed, and the suspended cleaning processing is executed from the beginning.
