FIG. 2 shows a control configuration of the control circuit 55.
The control configuration and operation of the electrolyzed water generator 1 will be described with reference to the flowchart of FIG.

The control circuit 55 firstly controls the flow rate detecting means 20
Detects whether water is flowing into the inflow passage 2 (S
1) When the flow rate detecting means 20 detects the inflow of water, the power supply to the electrolytic cells 3a and 3b is started (S
2) The processing of S4 described below is performed. When the flow rate detecting means 20 does not detect the inflow of water in S2, the power supply to the electrolytic cells 3a and 3b is stopped (S3), and the process of S1 is performed again.

Next, at S4, the PH detecting means 56
After inputting the pH of the alkaline water and the acidic water from a and 56b, in steps S5 and S6, the pH of the alkaline water and the acidic water input in S4 is stored in the PH storage means 54. And PH (S
5, S6).

As a result of the comparison in S5, when it is determined that the pH of the alkaline water detected by the PH detection means 56a is lower than the reference pH of the alkaline water stored in the PH storage means 54, or in S6 Comparison result, PH detection means 56b
Is determined to be higher than the reference pH of the acidic water stored in the PH storage means 54, the electromagnetic three-way valve 51 is connected to the cathode chamber outflow passage 18a and the bypass passage 22.
The electromagnetic three-way valve 52 is switched so that the anode chamber outflow passage 18b and the bypass passage 23 communicate with each other, and the electromagnetic on-off valve 53 is closed (S7).

Thus, when the flow rate or flow rate of the water flowing into the inflow passage 2 increases and the pH of the alkaline water decreases or the pH of the acidic water increases, the electrolytic cells 3a and 3b are connected in parallel. From the inflow channel 2 to the outflow channel for alkaline water (or the outflow channel for acidic water), the flow path resistance increases, and as a result, the flow velocity or the flow rate increases. At the same time, the water flowing in from the inflow passage 2 is electrolyzed in the electrolytic cell 3a and then electrolyzed again in the electrolytic cell 3b, so that higher pH alkaline water or lower PH acidic water can be obtained.

The comparison result in S5 indicates that the PH detection means 5
The PH of the alkaline water detected in 6a is stored in the PH storage means 54.
If it is determined that the pH is not lower than the reference pH of the alkaline water stored in the PH storage means 54, or if the PH detected by the PH detection means 56b If it is determined that the pressure is not higher than the reference PH, the electromagnetic three-way valve 51 is switched so that the cathode chamber outflow passage 18a and the alkaline water integration passage 19a communicate with each other, and the electromagnetic three-way valve 52 is switched to the anode chamber outflow passage The electromagnetic open / close valve 53 is opened by switching so that the 18b and the integrated passage for acidic water 19b communicate (S8).

As a result, the flow rate or flow rate of the water flowing into the inflow passage 2 increases, and the PH of the alkaline water is stored in the PH storage means 5.
When the pH of the alkaline water stored in the storage unit 4 is higher than the pH of the alkaline water or the pH of the acidic water is lower than the pH of the acidic water stored in the PH storage unit 54, the electrolytic cells 3a and 3b are connected in series. To the parallel connection, the distance of the flow path from the inflow path 2 to the outflow path 19a for alkaline water (or the outflow path 19b for acidic water) is reduced, so that the flow path resistance is reduced and the inflow path is reduced. 2, the flow rate or flow rate of the water flowing in increases, and as a result, the pH of the alkaline water discharged from the alkaline water outflow channel 19a (or the acidic water outflow channel 19b) decreases (or the pH of the acidic water increases). However, more alkaline water (or acidic water) can be obtained than when the electrolytic cell 3a and the electrolytic cell 3b are connected in series.

Next, a first modification of the embodiment will be described with reference to FIGS. FIG. 3 showing the second modified example.
In the figure, the same components as those of the embodiment shown in FIG. 1 are denoted by the same reference numerals, and the description of the components will be omitted.

3 differs from FIG. 1 in that the control circuit 55 is replaced with a PH setting means 64 for setting the pH of alkaline water or acidic water to be generated by the electrolyzed water generator 60. PH storage means 61 for storing the pH of alkaline water or acidic water set by the user in setting means 64
And a control circuit 63 having a reference PH storage means 62 for storing a PH serving as a reference for switching between the series connection and the parallel connection of the electrolytic cells 3a and 3b. .

FIG. 4 shows a control configuration of the control circuit 63.
The control configuration and operation of the electrolyzed water generator 60 will be described with reference to the flowchart of FIG.

The control circuit 63 first detects the flow rate
Detects whether water is flowing into the inflow passage 2 (S1).
1) When the flow rate detection means 20 detects the inflow of water, the power supply to the electrolytic cells 3a and 3b is started (S1).
2) The processing of S14 described below is performed. If the flow detecting means 20 does not detect the inflow of water in S12, the power supply to the electrolytic cells 3a and 3b is stopped (S13), and the process of S11 is performed again.

Next, at S14, the PH storage means 61
Of the reference PH stored in the reference PH storage means 62 is determined.

In S14, if it is determined that the pH of the alkaline water stored in the PH storage means 61 is lower than the reference pH of the alkaline water stored in the reference PH storage means 62, or if the comparison result in S15 is obtained. , PH storage means 61
If it is determined that the PH of the acidic water stored in the storage unit 62 is higher than the reference pH of the acidic water stored in the reference PH storage unit 62, the electromagnetic three-way valve 51 is connected to the cathode chamber outflow passage 18a and the bypass passage 22. The electromagnetic three-way valve 52 is switched so that the anode chamber outflow passage 18b and the bypass passage 23 communicate with each other, and the electromagnetic on-off valve 53 is closed (S16).

Thus, when the flow rate or flow rate of the water flowing into the inflow passage 2 increases and the pH of the alkaline water decreases or the pH of the acidic water increases, the electrolytic cells 3a and 3b are connected in parallel. From the inflow channel 2 to the outflow channel for alkaline water (or the outflow channel for acidic water), the flow path resistance increases, and as a result, the flow velocity or the flow rate increases. At the same time, the water flowing in from the inflow passage 2 is electrolyzed in the electrolytic cell 3a and then electrolyzed again in the electrolytic cell 3b, so that higher pH alkaline water or lower PH acidic water can be obtained.

If it is determined in step S14 that the pH of the alkaline water stored in the PH storage means 61 is not lower than the reference pH of the alkaline water stored in the reference PH storage means 62, or , S15, P
When it is determined that the PH of the acidic water stored in the H storage means 61 is not higher than the reference PH of the acidic water stored in the reference PH storage means 62, the electromagnetic three-way valve 51 is connected to the cathode chamber outflow passage. 18a and the alkaline water integrated passage 19a are switched to communicate with each other, and the electromagnetic three-way valve 52 is connected to the anode chamber outflow passage 1
8b and the integrated path for acidic water 19b are switched to communicate with each other, and the electromagnetic on-off valve 53 is opened (S17).

As a result, the flow rate or flow rate of the water flowing into the inflow passage 2 increases, and the PH of the alkaline water is stored in the PH storage means 6.
When the pH of the alkaline water stored in step 1 rises above the pH of the alkaline water or the pH of the acidic water drops below the pH of the acidic water stored in the PH storage means 61, the electrolytic cell 3a and the electrolytic cell 3b are connected in series. To the parallel connection, the distance of the flow path from the inflow path 2 to the outflow path 19a for alkaline water (or the outflow path 19b for acidic water) is reduced, so that the flow path resistance is reduced and the inflow path is reduced. 2, the flow rate or flow rate of the water flowing in increases, and as a result, the pH of the alkaline water discharged from the alkaline water outflow channel 19a (or the acidic water outflow channel 19b) decreases (or the pH of the acidic water increases). However, more alkaline water (or acidic water) can be obtained than when the electrolytic cell 3a and the electrolytic cell 3b are connected in series.

Next, a second modification of the embodiment will be described with reference to FIGS. FIG. 5 showing the second modified example.
In the figure, the same reference numerals are given to the same configurations as the configuration of FIG. 3 showing the above-described first modification, and the description of the configuration will be omitted.

5 differs from FIG. 3 in that the flow rate detecting means 20 is replaced with the electrolytic cell 3 of the electrolyzed water generator 70.
a, a flow rate detecting means 71 for detecting the flow rate or flow rate of the water flowing into the electrolyzed water generators 70 and 3b is provided instead of the control circuit 63; The only difference is that a control circuit 73 having a flow velocity storage means 72 for preliminarily storing the flow velocity or flow rate is provided. In the case where the flow rate detecting means 20 of the above-described embodiment detects the flow of water by detecting the flow rate of water, the flow rate detecting means 20 is directly used as the flow rate detecting means 71.
You may use as.

FIG. 6 shows a control configuration of the control circuit 73.
The control configuration and operation of the electrolyzed water generator 70 will be described with reference to the flowchart of FIG.

The control circuit 73 first comprises a flow rate detecting means 71
Detects whether or not water is flowing into the inflow passage 2 from the flow velocity or flow rate of the water (S21). If the flow velocity detecting means 71 detects the inflow of water, the flow is detected in the electrolytic cells 3a and 3b. (S22), the process of S24 described later is performed.
When the flow velocity detecting means 71 does not detect the inflow of water in S21, the power supply to the electrolytic cells 3a and 3b is stopped (S23), and the processing of S21 is performed again.

Next, at S24, the flow velocity detecting means 71
Then, the magnitude relation between the flow velocity or the flow rate detected by the above and the reference flow velocity or the flow rate stored in the flow velocity storage means 72 is determined.

If it is determined in step S24 that the flow rate or the flow rate detected by the flow rate detecting means 71 is not larger than the reference flow rate or the flow rate stored in the flow rate storing means 72, the electromagnetic three-way valve 51 is set to the cathode chamber. The outflow passage 18a and the alkaline water integrated passage 19a are switched so as to communicate with each other, and the electromagnetic three-way valve 52 is connected to the anode chamber outflow passage 18b and the acidic water integrated passage 1
9b, and the electromagnetic on-off valve 53 is opened (S25).

As a result, the flow rate or flow rate of the water flowing into the inflow passage 2 increases, and the PH of the alkaline water is stored in the PH storage means 5.
When the pH of the alkaline water stored in the storage unit 4 is higher than the pH of the alkaline water or the pH of the acidic water is lower than the pH of the acidic water stored in the PH storage unit 54, the electrolytic cells 3a and 3b are connected in series. To the parallel connection, the distance of the flow path from the inflow path 2 to the alkaline water outflow path 19a (or the acidic water outflow path 19b) is shortened, whereby the flow path resistance is reduced, and the inflow path 2 The flow speed or flow rate of the inflowing water increases, and as a result, the alkaline water P discharged from the alkaline water outflow passage 19a (or the acidic water outflow passage 19b) is discharged.
H decreases (or the pH of acidic water increases), but the electrolytic cell 3
More alkaline water (or acidic water) can be obtained than when a and the electrolytic cell 3b are connected in series.

At S24, the flow velocity detecting means 71
Is determined to be larger than the reference flow rate or the flow rate stored in the flow rate storage means 72, the electromagnetic three-way valve 51 communicates with the cathode chamber outflow passage 18a and the bypass passage 22. The electromagnetic three-way valve 52 is switched so that the anode chamber outflow passage 18b and the bypass passage 23 communicate with each other, and the electromagnetic on-off valve 53 is closed (S
26).

Thus, when the flow rate or flow rate of the water flowing into the inflow passage 2 increases and the pH of the alkaline water decreases or the pH of the acidic water increases, the electrolytic cells 3a and 3b are connected in parallel. From the inflow channel 2 to the outflow channel for alkaline water (or the outflow channel for acidic water), the flow path resistance increases, and as a result, the flow velocity or the flow rate increases. At the same time, the water flowing in from the inflow passage 2 is electrolyzed in the electrolytic cell 3a and then electrolyzed again in the electrolytic cell 3b, so that higher pH alkaline water or lower PH acidic water can be obtained.

In the second modified example, the electrolytic cell 3a and the electrolytic cell 3b are connected in series or in parallel based on the flow velocity or flow rate of the water flowing into the electrolytic cells 3a and 3b by the flow velocity detecting means 71. Although the connection or the connection is switched, the flow rate detecting means 71 is replaced with the electrolytic cells 3a, 3b.
A means for indirectly detecting the flow rate or flow rate of the water flowing into the electrolytic cells 3a and 3b from the internal pressure is used as a flow rate detecting means.
Needless to say, it may be switched between series connection and electrolytic cell 3b or parallel connection.

[0042]

As described above, according to the first aspect of the present invention, the generation PH reference switching control means determines whether one electrolytic cell and another electrolytic cell are based on the pH of alkaline water or acidic water detected by the PH detection means. It is determined whether the electrolytic cell and the electrolytic cell are connected in parallel or in series. Based on the result of the determination, the switching means switches between the one electrolytic cell and another electrolytic cell in parallel or in series. Therefore, when the pH of the alkaline water decreases or the pH of the acidic water increases, one electrolytic cell and another electrolytic cell are switched from parallel connection to series connection, and the flow from the inflow passage to the outflow passage is changed. The flow path resistance is increased by extending the distance of the path, and as a result, the flow velocity or the flow rate is reduced, and the water flowing in from the inflow path is electrolyzed in one electrolytic cell and then again in another electrolytic cell. Since it is electrolyzed, higher pH alkaline water or lower PH acidic water can be obtained. This eliminates the need for the user to operate the switching unit by checking the pH of the alkaline water or the acidic water generated in the electrolytic cell, thereby preventing the user from erroneously operating the switching unit.

According to a second aspect of the present invention, the set PH reference switching control means sets one electrolytic cell and another electrolytic cell in parallel based on the pH of the alkaline water or acidic water set by the PH setting means. It is determined whether connection is to be made in series or in series, and based on the result of this determination, switching means switches between one electrolytic cell and another electrolytic cell in parallel or in series. For this reason, one electrolytic cell and another electrolytic cell are switched from parallel connection to series connection based on the pH of the alkaline water (or the acidic water) set by the PH setting means, and the flow path from the inflow passage to the outflow passage is changed. The flow path resistance is increased by extending the distance, and as a result, the flow velocity or the flow rate is reduced, and the water flowing from the inflow path is electrolyzed in one electrolytic cell and then electrolyzed in another electrolytic cell. Therefore, it is possible to obtain higher pH alkaline water or lower pH acidic water without applying a high voltage to the electrolytic cell, so that the user can use the alkaline water or acidic water generated in the electrolytic cell. PH
Therefore, it is not necessary to operate the switching means after confirming the above, so that erroneous operation of the switching means by the user can be prevented. Further, in the present invention, the flow rate reference switching control means may be arranged such that, when the flow rate or flow rate of the water detected by the flow rate detection means is equal to or less than a predetermined flow rate or flow rate, the one electrolytic cell and the other electrolytic cell Are connected in parallel, and when the flow rate or flow rate of the water detected by the flow rate detection means exceeds a predetermined flow rate or flow rate,
By operating the switching means, one electrolytic cell and another electrolytic cell are changed from parallel connection to series connection. Therefore, when the flow rate or flow rate of water flowing into a plurality of electrolytic cells is large, one electrolytic cell and another electrolytic cell are switched from parallel connection to series connection, and the flow path from the inflow passage to the outflow passage is changed. The flow path resistance is increased by extending the distance, and as a result, the flow velocity or the flow rate is reduced, and the water flowing from the inflow path is electrolyzed in one electrolytic cell and then electrolyzed in another electrolytic cell. Therefore, higher pH alkaline water or lower pH acidic water can be obtained. Therefore, the user does not need to check the flow rate of the water flowing into the electrolytic cell and operate the switching means, thereby preventing the user from operating the switching means.
