Control is performed such that a positive voltage and a negative voltage (ground voltage) are supplied to the first and second electrode plates 39 and 40 of the electrolytic cell 18, respectively. When the raw water is supplied to the ionized water generator 11 and the frequency of the pulse signal PS of the flow rate sensor 31 becomes 20 Hz or more (the raw water supply amount is 1.5 liters per minute or more), the current control signal CI1 is sent to the regulator 70. Then, a DC voltage is supplied from the regulator 70 to the electrolytic cell 18 to perform the electrolysis of the raw water.

(B) When the Alkaline Water Mode (2) is Selected The controller 80 does not drive the electromagnetic three-way valve 48, connects the connection pipe 47 with the water intake pipe 13, and does not switch the switching relay 71. Control is performed such that a positive voltage and a negative voltage (ground voltage) are supplied to the first and second electrode plates 39 and 40 of the electrolytic cell 18, respectively. When the frequency of the pulse signal PS of the flow rate sensor 31 becomes 20 Hz or more (the raw water supply rate becomes 1.5 liters or more per minute), a current control signal CI2 is output to the regulator 70, and the regulator 70 sends the current control signal CI2 to the electrolytic cell 18. The DC voltage is supplied to perform the electrolysis of the raw water.

(C) When the Alkaline Water Mode (3) is Selected The controller 80 does not drive the electromagnetic three-way valve 48, communicates the connection pipe 47 with the water intake pipe 13, and does not switch the switching relay 71. Control is performed such that a positive voltage and a negative voltage (ground voltage) are supplied to the first and second electrode plates 39 and 40 of the electrolytic cell 18, respectively. When the frequency of the pulse signal PS of the flow sensor 31 becomes 20 Hz or more (the raw water supply amount becomes 1.5 liters or more per minute), the current control signal CI3 is output to the regulator 70, and the regulator 70 sends the current control signal CI3 to the electrolytic cell 18. The DC voltage is supplied to perform the electrolysis of the raw water.

(D) When the Strongly Acidic Water Mode is Selected The controller 80 outputs the valve switching signal BT to drive the electromagnetic three-way valve 48 so that the connection pipe 47 and the second drain pipe 15 communicate with each other. Control is performed such that a positive voltage and a negative voltage (ground voltage) are supplied to the first and second electrode plates 39 and 40 of the electrolytic cell 18 without switching the switching relay 71. The pulse signal P of the flow sensor 31
When the frequency of S becomes 20 Hz or more (the supply amount of raw water is 1.5 liters or more per minute), a current control signal CI4 is output to the regulator 70, and a DC voltage is supplied from the regulator 70 to the electrolytic cell 18 to perform the electrolysis of the raw water. Is performed.

(E) When the acidic water mode is selected The controller 80 outputs a valve switching signal BT to drive the electromagnetic three-way valve 48 to connect the connection pipe 47 to the second drain pipe 15 and to switch the connection. A relay switching signal RT is output to the relay 71 to control the switching relay 71 so that a negative voltage (ground voltage) and a positive voltage are supplied to the first and second electrode plates 39 and 40 of the electrolytic cell 18, respectively. And
The frequency of the pulse signal PS of the flow sensor 31 is 20 Hz
When the above (the raw water supply amount is 1.5 liters or more per minute), the current control signal CI3 is output to the regulator 70,
A direct voltage is supplied from the regulator 70 to the electrolytic cell 18 to perform the electrolysis of the raw water.

(F) When the Water Purification Mode is Selected The controller 80 does not drive the electromagnetic three-way valve 48, but only connects the connection pipe 47 and the water intake pipe 13 without controlling the switching relay 71. No current control signal is output to 70.

In this embodiment, the electrolytic currents corresponding to the current control signals CI1, CI2, CI3 and CI4 are set to 0.5 A, 1.5 A, 4 A and 6 A, respectively.

When one of the above six operation modes is selected by operating the selection switch 64, the controller 80 blinks the mode lamp corresponding to the selected operation mode. Then, the frequency of the pulse signal PS of the flow rate sensor 31 is 20 Hz or more (the raw water supply amount is 1.5
When the measured time exceeds the predetermined time (5 seconds in this embodiment), the mode lamp is turned on from the blinking state. By switching the mode lamp from the blinking state to the lighting state in this way, it can be seen that the water quality has been stabilized. In addition, the controller 80 causes the liquid crystal display 68 to blink and display that the mode is set in synchronization with the blinking of the mode lamp, and synchronizes the lighting of the mode lamp with the liquid crystal display 68 to display the ionized water or pure water in the mode. Is displayed indicating that is being generated. At the time of the generation of the water, the controller 80 causes the buzzer 67 to notify that the mode is the mode by a predetermined sound.

When the stable operation mode is the strong acidic water mode as described above, the controller 80 invalidates the pressing operation of the selection switch 64 and prohibits switching to an operation mode other than the strong acidic water mode. I have to. In this case, the valve switching signal BT is output, the electromagnetic three-way valve 48 continues to be driven, and the connection between the connection pipe 47 and the second drain pipe 15 is made to remain in the second ionization chamber 38. The strong alkaline water and the saline solution can be prevented from being discharged from the water intake pipe 13. In order to release the invalidation of the selection switch and switch to an operation mode other than the strong acid water mode, the faucet is closed to stop the supply of raw water, or the controller is operated based on the pressing operation of the power switch 63. The power supply to the power supply 80 may be cut off.

On the other hand, when the stable operation mode is an operation mode other than the strong acid water mode, the controller 80 changes the operation mode to strong acid based on the pressing operation of the selection switch 64 without stopping the supply of the raw water. Switch to any operating mode, including watery mode.

In the alkaline water modes (1), (2) and (3) and the acidic water mode, the controller 80 outputs the current control signals CI1 to CI3 during the output.
The 5-minute timer 84 is operated to integrate and measure the electrolysis time. In the alkaline water mode, the acid water mode and the strong acid water mode, the controller 80 controls the timer 8 for the electrolytic cell during the output of the current control signals CI1 to CI4.
6 is operated to integrate and measure the electrolysis use time of the electrolyzer 18. Further, the controller 80 operates the primary and secondary filter counters 87 and 88 to measure the pulse signal PS of the flow rate sensor 31 in the above-described six operation modes, so that the primary and secondary filters 16 and The use time of 17 is integrated.

The controller 80 determines whether the operation state of the ionized water generator 11 is one of the following three conditions.
If one is satisfied, the cleaning mode is automatically executed. (1) In the electrolysis in the alkaline water mode and the acidic water mode, when the time counted by the 15-minute timer 84 reaches the accumulated 15 minutes and the count-up signal is output to the controller 80.

(2) Electrolyzer 1 using 24-hour timer 85
8 when the measurement time during which the electrolysis is not performed reaches 24 hours and the count-up signal is output to the controller 80.

(3) When the alkaline water mode, the acid water mode, or the water purification mode is first executed based on the operation of the selection switch 64 after the operation in the strong acid water mode is completed.

In this cleaning mode, the controller 80 outputs the valve switching signal BT to drive the electromagnetic three-way valve 48 to make the connection between the connection pipe 47 and the second drain pipe 15 and to relay the signal to the switching relay 71. A switching signal RT is output to control the first and second electrode plates 39 and 40 to supply a negative voltage (ground voltage) and a positive voltage, respectively. When the frequency of the pulse signal PS of the flow sensor 31 becomes 20 Hz or more, the controller 70 outputs a current control signal CI3 to the regulator 70, and the regulator 70
8 is supplied with a DC voltage to perform electrolysis of raw water. As a result, calcium and the like deposited on the surface of the second electrode plate 40 of the electrolytic cell 18 are electrolyzed, and calcium and the like deposited in the main body 49 of the connection pipe 47 and the electromagnetic three-way valve 48 enter the second ionization chamber 38. The ionic water dissolved in the generated acidic water and remaining in the electrolytic cell 18 is discharged.
In the cleaning mode after the strong acidic water mode, the saline solution remaining in the electrolytic cell 18 is also discharged. The cleaning time is set within a range from 10 seconds to 60 seconds in consideration of the waiting time of the user. In the present embodiment, the output continuation time of the current control signal CI3 in the cleaning mode is set to 25 seconds, and the valve switching signal BT is stopped 5 seconds after the output of the current control signal CI3 is stopped. The cleaning mode is continued for 30 seconds after the start of electrolysis. In this cleaning mode, a melody is set to flow to notify the user of the use state.

When the accumulated time is measured by the electrolytic cell timer 86 and the count-up signal is output, the controller 80 displays on the liquid crystal display 68 that the time to replace the electrolytic cell 18 has been reached, and , Is notified by the buzzer 67. At this time, the controller 8
0 is selected by stopping the output of the valve switching signal BT, the relay switching signal RT, and the current control signals CI1 to CI4, controlling the electromagnetic three-way valve 48 and the switching relay 71, and stopping the voltage supply to the electrolytic cell 18. Cancel the current operation mode.

The controller 80 calculates the total of 9 by the primary or secondary filter counters 87 and 88, respectively.
When 600,000 pulses and 6 million pulses are measured and the count-up signal is output, when the supply of the raw water to the ionic water generator 11 is stopped, the liquid crystal display 68 replaces the primary or secondary filters 16 and 17. Is reached, and a buzzer 67 informs the user of this by sound. When the supply of the raw water to the ionized water generator 11 is restarted, the controller 80 controls the voltage to the electromagnetic three-way valve 48, the switching relay 71, and the electrolytic cell 18 according to the selected operation mode. Produces ionized water or pure water.

Further, the controller 80 is a bimetal 2
Various errors are displayed by the liquid crystal display 68 on the basis of the detection result of 5, the detection result of the flow sensor 31, the detection result (instruction signal) of the regulator 70, and the like, and an error is notified by the buzzer 67.

These error displays and notifications include insufficient hydraulic pressure, excessive hydraulic pressure, a state where salt is not supplied, a state where salt is erroneously supplied,
There is a hot water error or a heating error. That is, when any one of the above six operation modes is selected based on the operation of the selection switch 64, the frequency of the detection signal of the flow sensor 31 is less than a predetermined value (5 Hz or more and 20 Hz or less in the present embodiment). Is a predetermined time (5 seconds in this embodiment)
When the above is continued, the controller 80 causes the liquid crystal display 68 to display an error indicating that the water pressure is insufficient,
An error notification is made by the buzzer 67.

When the frequency of the detection signal of the flow rate sensor 31 becomes a predetermined value or more (50 Hz or more in this embodiment) in a state where the strong acid water mode is selected based on the operation of the selection switch 64, the controller 80 is turned on. The liquid crystal display 68 displays an error indicating that the water pressure is excessive, and the buzzer 67 provides an error notification.

When the strong acid water mode is selected based on the operation of the selection switch 64, a predetermined time (20 seconds in this embodiment) is required until the strong acid water mode becomes a steady state. Therefore, the instruction signal SD1 indicating that the output voltage of the regulator 70 is 10 V or more is 2
If output is continued for 0 seconds or more, the controller 80 determines that the generated water is not strong acid water or strong alkaline water because the output voltage is too high, and the liquid crystal display 68 indicates that salt has not been input. An error message “Insert salt” is displayed, and an error is reported by the buzzer 67. At this time, the controller 80 cancels the currently selected strong acidic water mode by stopping the output of the current control signal CI4 and stopping the voltage supply to the electrolytic cell 18.

When one of the alkaline water modes (1), (2) and (3) is selected based on the operation of the selection switch 64, a predetermined time is required until the alkaline water mode becomes a steady state. (3 seconds in this embodiment)
Cost. Therefore, if the state in which the output voltage of the regulator 70 is equal to or lower than the voltage set for each mode is continued for 3 seconds or more, the controller 80 determines that the output water is too low and the generated water is strongly acidic or strongly alkaline Is determined, the liquid crystal display 68 displays an error message indicating that salt is being erroneously input, and “removes salt”, and the buzzer 67 gives an error notification. In the present embodiment, when the instruction signal SD3 in which the output voltage of the regulator 70 is 2 V or less is continuously output for 3 seconds or more when the alkaline water mode (1) is selected, the alkaline water mode (2) is selected. When the instruction signal SD2 indicating that the output voltage of the regulator 70 is 5 V or less is continuously output for 3 seconds or more in the state where the alkaline water mode (3) is selected, the output voltage of the regulator 70 is selected. Is 7V or less,
That is, when none of the instruction signals SD1 to SD3 is continuously output for 3 seconds or more, an error display and an error notification indicating that the salt is erroneously input are performed. At this time, the controller 80 cancels the selected alkaline water mode by stopping the output of the current control signals CI1 to CI4 and stopping the voltage supply to the electrolytic cell 18.

Further, when it is detected by the bimetal 25 that hot water has been supplied to the ionized water generator 11,
The controller 80 causes the liquid crystal display 68 to display a hot water error and causes the buzzer 67 to notify the error. At this time, the controller 80 controls the valve switching signal BT, the relay switching signal RT, and the current control signal C
By stopping the outputs of I1 to CI4 and stopping the control of the electromagnetic three-way valve 48 and the switching relay 71 and the supply of voltage to the electrolytic cell 18, the selected operation mode is canceled. This is because when hot water is supplied to the ionic water generator 11, the antibacterial granular activated carbon 20 and the fibrous activated carbon 26 of the primary and secondary filters 16, 17 may release adsorbed trihalomethane and the like into raw water. The product water is prevented from being inadvertently consumed.

When it is detected by the thermostat 72 that the regulator 70 has overheated to a predetermined temperature or more and the temperature protection signal SH is output, the controller 80 causes the liquid crystal display 68 to display an overheat error display and a buzzer 67. Error notification. Also in this case, the controller 80 outputs the valve switching signal BT,
The output of the relay switching signal RT and the current control signals CI1 to CI4 is stopped, and the control of the electromagnetic three-way valve 48 and the switching relay 71 and the supply of voltage to the electrolytic cell 18 are stopped to cancel the selected operation mode.

Next, the operation of the ionic water generator 11 configured as described above will be described. The water supply pipe 23 is connected to a water tap with the ion water generation device 11 placed near the sink and the distal ends of the first and second drain pipes 14 and 15 positioned in the sink. Then, when the power plug is inserted into the outlet, the installation of the ionized water generator 11 is completed.

In this state, when the faucet is opened and the supply of raw water is started, the primary and secondary filters 16 and 17 are opened.
Thus, the raw water is purified and supplied to the electrolytic cell 18. When the flow rate of the raw water supplied into the electrolytic cell 18 becomes 1.5 liters or more per minute, the controller 80
Output current control signal CI3. A negative voltage (ground voltage) is applied to the first electrode plate 39 so that an electrolytic current (4 A) according to the current control signal CI3 flows,
A positive voltage is applied to the second electrode plate 40. In the electrolytic cell 18, magnesium ions (Mg ²⁺ ), sodium ions (Na ⁺ ), potassium ions (K ⁺ ), calcium ions (Ca ²⁺ ) and the like in the raw water are attracted to the first electrode plate 39, and ion (OH ^-), sulfate ion (S
O ₄ ^2- ), nitrate ion (NO ₃ ^2- ), chlorine ion (C
l ⁻ ) are drawn to the second electrode plate 40. As a result, calcium and the like deposited on the surface of the second electrode plate 40 of the electrolytic cell 18 are electrolyzed, so that alkaline alkaline water is generated in the first ionization chamber 37 and acidic water is generated in the second ionization chamber 38. Generated.

With the supply of raw water into the electrolytic cell 18, the first
The alkaline water in the ionization chamber 37 is discharged from the first discharge port 45 to the first
The acid water discharged through the drain pipe 14 and in the second ionization chamber 38 flows from the second discharge port 46 to the connection pipe 47 and the electromagnetic three-way valve 48.
And discharged through the second drain pipe 15. Accordingly, calcium and the like precipitated in the connection pipe 47 and the main body 49 of the electromagnetic three-way valve 48 are dissolved by the acidic water in the second ionization chamber 38, and the ionic water remaining in the electrolytic cell 18 is discharged. . In the cleaning mode after the strong acidic water mode, the saline solution remaining in the electrolytic cell 18 is also discharged.
This cleaning mode is continued for 30 seconds. After the end of the cleaning mode, the operation mode is automatically switched to the operation mode set based on the operation of the selection switch 64,
The operation in the operation mode is performed.

In the present embodiment, the following effects can be obtained by configuring the ionized water generator 11 as described above.・ At the time of strong acid water mode and cleaning mode,
The electromagnetic three-way valve 48 was switched so that the connection pipe 47 and the second drain pipe 15 became a water flow path in the second ionization chamber 38. In addition, in the alkaline water mode, the acidic water mode, and the water purification mode, the connection pipe 47 and the water intake pipe 13 serve as a water flow path in the second ionization chamber 38 without switching the electromagnetic three-way valve 48. As described above, unsuitable water such as strong alkaline ionized water generated in the second ionization chamber 38 in the strongly acidic water mode, acidic ionized water generated in the second ionization chamber 38 in the cleaning mode, and saline. By switching the electromagnetic three-way valve 48 so as to take it out of the drain pipe 15 without taking it out of the water intake pipe 13, accidental ingestion can be prevented.

Since the switching of the electromagnetic three-way valve 48 is controlled by the controller 80 according to the operation mode, the intake pipe 13 and the second drain pipe 15 can be automatically switched.

When the alkaline water mode is selected, the controller 80 sets the polarity of the second electrode plate 40 of the second ionization chamber 38 to which the electromagnetic three-way valve 48 is connected as the cathode, and connects the three-way valve 48 to the water pipe 13. , The desired alkaline water can be easily collected.

When the operation mode is switched from the strong acidic water mode to the alkaline water mode or the acidic water mode, the cleaning mode is automatically performed, and then the mode is switched to the alkaline water mode or the acidic water mode. Therefore, unsuitable water such as strong alkaline ionized water and saline generated in the second ionization chamber 38 in the strong acid water mode can be taken out from the drain pipe 15, and accidental drinking can be prevented. it can.

After a predetermined time elapses from the switching from the strong acidic water mode to the alkaline water mode or the acidic water mode, and the alkaline water mode or the acidic water mode being in a steady state, the controller 80 outputs the voltage based on the output voltage of the regulator 70. It is determined whether the generated water in the electrolytic cell 18 is a strongly acidic ionic water or a strongly alkaline ionic water, and if so, the electrolysis in the electrolytic cell 18 is stopped and the salt is erroneously charged. Is displayed on the liquid crystal display 68 as an error, and a buzzer 67 is used to notify by sound. Therefore, it is possible to easily recognize that the water collected from the intake pipe 13 is unsuitable for drinking, and to prevent accidental drinking. At this time, it is possible to easily cope with the error display "Remove salt".

When switching from the alkaline water mode or the acidic water mode to the strong acidic water mode, after a predetermined time elapses until the mode is switched to the strong acidic water mode and a steady state is established, the controller 80 performs the electrolysis based on the output voltage of the regulator 70. It is determined whether the generated water in the tank 18 is strongly acidic ionic water or strongly alkaline ionic water, and if not,
The electrolysis in the electrolysis tank 18 was stopped, and the fact that salt was not supplied was notified. Therefore, it can be easily recognized that the water discharged from the first drain pipe 14 is not strongly acidic water. Also, at this time, it is possible to easily cope with the error display of "insert salt".

The salt supply tube 32 is provided in the water supply line for supplying the raw water to the electrolytic cell 18, and the cartridge 32 a containing the salt is set in the salt supply tube 32. Can be added.

When the supply of raw water in the strongly acidic water mode is stabilized, the pressing operation of the selection switch 64 for selecting the operation mode is invalidated, and the switching to another mode is prohibited. Therefore, the connecting pipe 47 and the second drain pipe 1
5 is kept in communication with the second ionization chamber 38.
Take the strong alkaline water and saline remaining in the water pipe 13
Can be prevented from being discharged from the container, and accidental ingestion of water that is inappropriate for drinking can be prevented. When the faucet is closed and the supply of raw water to the ionized water generator 11 is stopped, the invalidation of the pressing operation of the selection switch 64 can be easily canceled.

The operation panel 62 is provided with only one selection switch 64 for setting an operation mode.
Since the operation modes are switched one by one, it is possible to suppress an increase in the size of the operation panel 62.

The alkaline water mode is divided into a plurality of (three) modes depending on the strength of the alkalinity, so that alkaline water having a desired alkali strength can be generated and consumed.

Since the ultrafiltration membrane 27 with a finer filtration causes clogging earlier, the ultrafiltration membrane 27 with a finer filtration is frequently replaced, and the hollow fiber membrane 21 with a coarser filtration is less likely to be clogged. Can be smaller. That is, different filter containers are used depending on the density of the filtration mesh, so that the most appropriate replacement time can be selected.

8 and the fact that the time for replacing the electrolytic cell 18 has been reached is displayed on the liquid crystal display 68, and the buzzer 67 sounds to notify the user.
Can be replaced at an appropriate time. At the time of notification of the replacement time of the electrolytic cell 18, the selected operation mode is stopped by controlling the electromagnetic three-way valve 48 and the switching relay 71 and stopping the voltage supply to the electrolytic cell 18. This is not performed, and functions such as leakage prevention of the electrolytic cell 18 can be guaranteed.

When the hot water is supplied, the hot water is detected by the bimetal 25 quickly, a hot water error is displayed on the liquid crystal display 68, and the buzzer 67 sounds to notify the user. Therefore, when hot water is supplied, trihalomethane or the like may be released from the antibacterial granular activated carbon 20 and the fibrous activated carbon 26 into the water generated in the second ionization chamber 38, but the generated water is displayed by the hot water error display and notification. Accidental ingestion can be prevented.

When the regulator 70 is overheated, it is detected by the thermostat 72, an overheat error is displayed by the liquid crystal display 68, and the buzzer 67 sounds to notify the user. At this time, the electromagnetic three-way valve 48
The operation mode being selected is stopped by stopping the control of the switching relay 71 and the supply of voltage to the electrolytic cell 18, so that the temperature of the regulator 70 can be protected.
