23 for program selection provided on the side plate 19 of the
To the male side 23a (hereinafter, referred to as male side 23a) of the electric control device 10 inside. The program selection connector 23 has the same structure as the control signal input / output connector 21 in cross section, and the male side 23a has five connection pins 23b penetrating the center of its main body (FIGS. 4 and 3). (See (A) and (B)). Of the connection pins 23b shown in FIGS. 3A and 3B, the leftmost connection pin 23b in the figure is grounded via the connector 18 of FIG. ". Further, the first pin, the second pin, the third pin, and the fourth pin are formed in order from the second connection pin 23b from the left in the figure.

The pin receiver 23d penetrates through the main body on the female side 23c, and the connecting wire 24 having a pin-shaped tip portion can be inserted from the other side of the pin receiver 23c.

FIG. 3A shows the female side 23c in which both ends of the connecting wire 24 are inserted into the pin receivers 23d located at the first and second positions from the left in the figure. When the female side 23c is connected to the male side 23a, the ground pin and the first pin are connected, the first pin is "short-circuited", and the second to fourth pins are kept "open". or,
In FIG. 3B, both ends of the connection line 24 are 1,
The female side 23c is shown inserted into the fourth and fifth pin receivers 23d.
When c is connected to the male side 23a, pins 3 and 4 are short-circuited, and pins 1 and 2 are kept open. The female side 23c is bound to the control signal line 22 by a binding band 25 that surrounds the control signal line 22 through a loop formed by the connecting line 24 and the female side 23c, and the female side 23c from the male side 23a. It is constructed so that it will not be lost when it is pulled out (see FIG. 1).

The display panel 30 shown in FIG. 2 is mounted on the front surface of the electric control device 10 to display the operating state of the electrolyzed water producing device and to write (change) the data stored and held by the EEPROM 14. The first to sixth switches 31 to 36, numeral display portions 37a and 37b made of LEDs, a warning lamp 38, a power switch 39 and the like are provided on the front surface of the display panel 30. It is provided. The display panel 30 is
It is connected to the connector 15 on the substrate 12 by a connector (not shown) and a lead wire (not shown).

Data input (writing instruction) from the display panel 30 to the EEPROM 14 is performed by the operator pressing the second switch 32 once to enter the writing mode and then changing the data in the EEPROM 14 to be changed by the first switch 31. After specifying the type and operating the third and fourth switches 33 and 34 to input desired data (numerals display portions 37a, 37
(displayed in b)), and when the second switch 32 is pressed again, the completion (writing instruction is generated) is configured.

Next, the operation of the electric control unit 10 configured as above will be described. First, at the time of manufacturing (at the time of shipment), an operator sets the female side 23c of the program selection connector 23 shown in FIG. 3B, which is prepared for an injection type electrolyzed water generator, to an electric control device. 10 is inserted into the male side 23a provided on the side plate 19 to be connected. After that, the electric control device 10 is incorporated in the electrolyzed water producing device main body 50 and shipped, and the electrolyzed water producing device main body 50 is installed on site.

When the power switch 39 on the display panel 30 is turned on after the electrolyzed water producing apparatus main body 50 is installed, the microcomputer 13 executes the program shown in the flowchart of FIG. 6 stored in the ROM. It starts from step 600 and proceeds to step 605.

In step 605, the connector 23
The connection status of the connection pin 23b (state of the connection terminal) is confirmed. That is, it is determined whether or not the state is "no connection pin is short-circuited". Female side 23 shown in FIG. 3 (B)
Since pin 3 and pin 4 are grounded (short-circuited) on the male side 23a of the connector 23 in which c is inserted, the microcomputer 13 determines step 605 to be “No” and proceeds to step 610. The warning lamp 38 on the display panel 30 is turned off. The lighting control of the warning lamp 38 will be described later.

Following step 610, the microcomputer 13 proceeds to step 615 and executes the common program. The common program is a program that is commonly executed for the three types of electrolyzed water generators in which the electric control device 10 is scheduled to be used, and, for example, a program that measures the current flowing between the electrodes of the electrolytic cell, A program for detecting the temperature of raw water.

After the execution of the common program, the microcomputer 13 proceeds to step 620 and proceeds to step 3 of the male side 23a.
It is determined whether the No. 4 pin and the No. 4 pin are short-circuited. Since pins 3 and 4 are short-circuited at this point, step 620 is determined as “Yes” and step 6
Go to 25 and execute the "A program". The “A program” is a program peculiar to the injection type electrolyzed water generator, and is, for example, a pump (a discharge amount of a pump) for adjusting the amount of concentrated salt water mixed in the raw water continuously supplied to the electrolyzed water. This is a program for generating electrolyzed water including a routine for controlling.

The microcomputer 13 executes step 6
After the processing of 25, the process returns to step 615 again to execute the common program, and thereafter, steps 620, 625, 615.
Repeat step. By the above operation, control suitable for the injection-type electrolyzed water producing apparatus is executed, and electrolyzed water is produced.

Next, at the time of manufacturing (at the time of shipping), FIG.
A case will be described in which the female side 23c in which the pin receivers 23c located at the first, second, third, and fifth positions from the left in FIG. The female side 23c is used when controlling a tank-type electrolyzed water generator, and the male side 23a.
Short-circuit pins 1, 2 and 4. The electric control device 1
0 is installed in the body of the tank-type electrolyzed water generator.

When the power switch 39 is turned on after the electrolyzed water producing apparatus main body is installed, the microcomputer 13 executes the program of FIG. 6 in steps 605, 610 and 615 and then proceeds to step 620. , 2 and 4 are short-circuited, the step 620 is judged as “No” and the process proceeds to the step 630. Since step 630 is a step of determining whether or not pins 1, 2, and 4 are short-circuited, the microcomputer 13 determines “Yes” and proceeds to step 63.
Go to 5.

In step 635, the microcomputer 13 executes a program (B program) for electrolyzed water production including a program specific to the tank electrolyzed water production apparatus. The specific program is, for example, a program for controlling the amount of concentrated salt water supplied from the concentrated salt water tank to the diluted salt water tank. After executing step 635, the microcomputer 13 returns to step 615 again, and repeats steps 620, 630 and 635 thereafter. As described above, the control suitable for the tank-type electrolyzed water producing apparatus is executed to produce electrolyzed water.

Similarly, when controlling the raw water type electrolyzed water generator, the female side 23c for short-circuiting the second and third pins is inserted into the male side 23a before shipment. In this case, the microcomputer 13 causes the steps 620, 6
Both 30 are determined to be “No”, and a program (C program) including a program specific to the raw water type electrolyzed water producing apparatus is executed.

If the female side 23c is not connected for some reason, the microcomputer 13 makes a "Yes" determination at step 605 following step 600, proceeds to step 645, and proceeds to step 645 to display panel 30. The upper warning lamp 38 is turned on and the female side 23c
Indicates that is not connected.

As described above, the microcomputer 13 stores in advance a plurality of programs (A, B and C programs) corresponding to the electrolyzed water producing apparatus to be used, and the connector 23 for program selection is used. The program is selected and executed according to the short-circuit / open state of the connection pin 23b, that is, the connection terminal state. Therefore, at the time of manufacture (at the time of shipment), it is possible to change to an electric control device that achieves a desired control simply by inserting and connecting the female side 23c of the predetermined connector 23 into the male side 23a. That is, the electric control device 10 has an advantage that model setting (specification setting) can be performed very easily. It should be noted that if a connector having n connection pins that can select short circuit or open circuit is used, 2 ⁿ kinds of specifications can be set.

Next, the second embodiment will be described. The second embodiment is the microcomputer 1 of the first embodiment.
3 stores the program shown in the flowchart of FIG. 6 in the ROM and executes the program, the microcomputer 13 of the second embodiment stores the program shown in the flowchart of FIG. 7 in the ROM. Only the execution point is different from the first embodiment. Therefore, the operation will be mainly described below.

First, at the time of shipment, the female side 23c of the connector 23 for grounding (short-circuiting) the pins 1 and 4 of the connector 23 is male so that the electrical control device 10 is suitable for the injection type electrolyzed water producing device. It is connected to the side 23a. After the electric control device 10 is housed in the electrolyzed water producing device main body 50 and installed at the site, the power switch 3
9 is input, the microcomputer 13 executes the program shown in the flowchart of FIG.
Start from 00.

At the following step 705, the microcomputer 13 determines whether or not pins 1 and 4 of the connector 23 are short-circuited. As described above, since the pins 1 and 4 are short-circuited, the microcomputer 13 determines step 705 to be “Yes” and proceeds to step 710. Step 710 is a step of executing a program (A program) dedicated to the control of the injection-type electrolyzed water generator, and the microcomputer 13
After that, the program A continues to be executed. In this way
The electric control device 10 executes control suitable for an injection-type electrolyzed water generation device.

Similarly, the electric control unit 10 includes a connector 2
Female side 23 that shorts pins 2 and 4 to male side 23a of 3
When c is inserted, the device is changed to a device suitable for a tank-type electrolyzed water generating device. That is, in this case, the microcomputer 13 determines the above-mentioned step 705 as “No”, proceeds to step 715 for determining whether the second and fourth pins are short-circuited, and the step 715 returns “Yes”. "
And proceeds to step 720, and thereafter, step 7
At 20, the program (B program) dedicated to the control of the tank-type electrolyzed water generator is continuously executed.

The microcomputer 13 returns "No" in both step 705 and step 715.
If it is determined that the female side 23c of the connector 23 is not inserted or the female side 23c which is not planned is inserted, the warning lamp 38 is turned on at step 725.

As described above, the microcomputer 13 in the second embodiment stores a plurality of programs dedicated to the electrolyzed water producing apparatus to be controlled in the ROM (storage section), and the connecting pin ( A program dedicated to the electrolyzed water generator (model) to be controlled according to the state of the connection terminal) is selected and executed. Therefore, the electric control device 10 of the second embodiment is suitable when a plurality of models that do not have a common program are targets of control. The electric control device 10 that achieves the control according to the model to be controlled can be obtained only by inserting the female side 23c of the connector 23 corresponding to the model to be controlled into the male side 23a. It is similar to the embodiment.

Next, a third embodiment will be described. The electric control device 10 according to the third embodiment is compatible with two types of tank-type electrolyzed water generators that generate a large amount of electrolyzed water per unit time and tank-type electrolyzed water generators that generate a small amount of electrolyzed water. There is. In this case, the basic operation of the control itself is the same for both models, but for example, the flow rate of concentrated salt water to be supplied from the concentrated salt water tank to the diluted salt water tank necessary to bring the concentration of diluted salt water to be electrolyzed to a predetermined value. Since the (concentrated salt water amount) is different, it is necessary to control the electromagnetic valve for controlling the concentrated salt water amount differently.

Specifically, the electromagnetic valve connects the concentrated salt water tank and the dilute salt water tank during the output period of the Hi signal in the pulse train signal in which the Hi (high level) signal and the Lo (low level) signal are repeated at a predetermined cycle. Open the flow path to control the flow rate of concentrated salt water. Therefore, in order to make the salt water concentrations in the dilute salt water tanks having different volumes the same between both models, even if the salt water concentration sensor outputs in the dilute salt water tank are the same, Hi
It is necessary to make the signal output periods different. Therefore, the microcomputer 13 predetermines a characteristic of the pulse train signal to be output to the electromagnetic valve with respect to the output of the salt water concentration sensor (having the same cycle but different output time of the Hi signal) as predetermined data in the ROM in advance. The program is stored in the area and the program (stored in the ROM) shown in the flowchart of FIG. 8 is executed. The other points are the same as those in the first embodiment.

First, the male side 23a of the connector 23 is shorted to the female side 23 for short-circuiting pins 1 and 4 of the connector 23.
Explaining the case where c is inserted and connected,
Power switch 39 by user after installation of electrolyzed water generator
8, the microcomputer 13 starts the program of FIG. 8 from step 800 and proceeds to step 805 to determine whether pins 1 and 4 of the connector 23 are short-circuited. At this point, since pins 1 and 4 of the connector 23 are short-circuited, the microcomputer 13 determines that step 805 is “Yes” and determines step 810.
Proceed to.

In step 810, step 82 described later is executed.
The characteristic data of the pulse train signal used for the electrolyzed water generation program executed at 0 is transferred from a predetermined (storage) area of the ROM to a specific (storage) area of the RAM to set the data. This data is adapted to a large capacity tank type electrolyzed water generator (model A). Thereafter, the microcomputer 13 turns off the warning lamp 38 that is turned on in step 835, which will be described later, in step 815.
Is executed to proceed to step 820, and the electrolyzed water generation program is executed.

In the execution of this electrolyzed water producing program, for example, when the output of the salt concentration sensor in the dilute salt water tank indicates that it is smaller than the target salt concentration, the electric control unit 10
Outputs a pulse train signal for increasing the flow rate of concentrated salt water into the diluted salt water tank to the electromagnetic valve. At that time, the data set in the specific region in step 810 is used to output the pulse train signal in the pulse train signal. The output period of the Hi signal is determined. As described above, the control adapted to the large-capacity tank type electrolyzed water producing apparatus is executed.

In order for the electric control unit 10 to control the small-capacity tank type electrolyzed water producing apparatus, the female side 23c of the connector 23 for short-circuiting pins 2 and 4 of the male side 23a of the connector 23 is shorted. Insert and connect. In this case, the microcomputer 13 determines step 805 to be “No” and proceeds to step 825 to determine whether or not pins 2 and 4 are short-circuited.

In step 825, the microcomputer 13 determines "Yes", so step 83
Go to 0, small capacity tank type electrolyzed water generator (model B)
The characteristic data of the pulse train signal adapted to the above is transferred from a predetermined area of the ROM to a specific area of the RAM described above to set the data. After that, the microcomputer 13
Goes to step 820 through the above-mentioned step 815 to execute the electrolyzed water producing program common to the high-capacity electrolyzed water producing apparatus. The data used at this time is the small-capacity tank electrolyzed water producing apparatus. Therefore, as a result, the control adapted to the small-capacity tank type electrolyzed water generator is executed. If the female side 23c of the connector 23 is forgotten to be inserted, the microcomputer 13 executes "N" in both steps 805 and 825.
It is determined to be “o”, and the warning lamp 38 is turned on in step 835 to notify that the connector is forgotten to be inserted.

As is apparent from the above, in the third embodiment, the data set in step 810 or step 830 is a large-capacity or small-capacity tank type electrolytic water generator (model to be controlled). In this case, as a result, the microcomputer 13 executes control suitable for both models. The third embodiment is a case in which there is a program that can be commonly used by the models controlled by the electric control device 10.
It is suitable when it is possible to perform control suitable for each model by changing only the data used for the program. Generally, a large capacity is required to store the program, but the data is relatively small capacity, so the third embodiment is also effective when the ROM capacity of the microcomputer 13 is limited.

Next, a fourth embodiment will be described. The electrical control device 10 of the fourth embodiment is the same as that of the third embodiment shown in FIG.
Instead of the above, the program shown in the flowchart of FIG. 9 is used, and the EEPROM 14 on the substrate 12 is used as a specific area for setting model-specific data in the third embodiment.
(Internal storage area) is used. The other points of the fourth embodiment are the same as those of the third embodiment.

First, while the user presses (turns on) the first switch 31 of the display panel 30 (see FIG. 2), the power source 3
To describe the case where 9 is input, the microcomputer 13 starts the program of FIG. 9 from step 900,
Then, step 905 which determines whether the first switch 31 is turned on is determined as “Yes” and the process proceeds to step 910.

By the way, when the electric controller 10 is shipped or when the board 12 is replaced, the data of each address in the EEPROM 14 is "00" or "FF" (hexadecimal notation). , EEPROM used by the electrolyzed water generation program (see step 925) described below
It is necessary to initialize the data (storage contents) in 14 to a basic value suitable for the electrolyzed water generating apparatus to be controlled. Step 910 is a step of performing this initialization. At that time, the microcomputer 13 outputs data corresponding to the short-circuited state of each connection pin of the connector 23 (which pin is short-circuited) from a predetermined area of the ROM. Read and EEPROM
Write to 14 and store.

After that, the microcomputer 13 proceeds to step 915 and displays the EEPROM 14 from the display panel 31.
It is determined whether or not there is an instruction to write data to (such as the operation of the second switch 32 described above). Normally, EEPRO
Since there is no write instruction to M14, the microcomputer 13 proceeds to step 925 and executes the electrolyzed water generation program at step 925. This electrolyzed water generation program is similar to the electrolyzed water generation program of the third embodiment, but is configured to use the data in the EEPROM 14 when it is executed. Therefore, the microcomputer 13 executes control using the data selected according to the short-circuit state of the connection pin of the connector 23.

On the other hand, it is possible to write data (change data) to the EEPROM 14 in order to finely adjust the control amount in accordance with the installation environment of the electrolyzed water generator (for example, the type of raw water). That is, when the microcomputer 13 determines in step 915 that there is a data write instruction, the microcomputer 13 proceeds to step 920, and step 92
At 0, the value set by the display panel 31 is written in a predetermined storage area in the EEPROM 14 corresponding to the designated data type, and then the process proceeds to step 925 to execute the electrolyzed water generation device program. Therefore, the microcomputer 13 thereafter controls the electrolyzed water producing apparatus using the changed data.

Incidentally, in a normal case where the user turns on the power switch 39 without pressing (turning on) the first switch 31, the microcomputer 13 causes the step 90 to proceed.
The process proceeds to 0, 905, and 915, and if there is no writing instruction from the display panel 31, the electrolyzed water generation program of step 925 is executed, and after execution, the process returns to step 915.

According to the fourth embodiment described above, when the predetermined condition (condition for initializing the data in the EEPROM 14) is satisfied, that is, the condition that the first switch is pressed to turn on the power switch is satisfied. At this time, the data in the EEPROM 14 used in the electrolyzed water generation program is
It is initialized to a value suitable for the model to be controlled. In addition, the data initialized by writing the data from the display panel 30 can be changed.
It is possible to achieve control suitable for the installation environment.
This also means that even if the installation location of the device is changed after the data in the EEPROM 14 is changed according to the installation environment of the device, the data in the EEPROM 14 must be initialized again. Even in such a case, the present apparatus can initialize the data in the EEPROM 14 by pressing the first switch and turning on the power switch, and the complicated work of initializing the data can be omitted. Have advantages.

In step 905, a predetermined condition (E
The determination of whether or not the condition for initializing the data of the EPROM 14) is established by determining "whether or not the first switch 31 is turned on". EE when the board 12 is replaced
Since the data in the PROM 14 is "FF" or "00", it is determined in step 905 "whether the data in the EEPROM 14 is a predetermined value (" FF "," 00 ")". , If it is a predetermined value, step 9
It may be configured to proceed to 10. In this case, the operator does not need to press the first switch 31, so the workability associated with the initialization is improved.

Next, the fifth embodiment will be described.
The fifth embodiment is a connector 2 used in the first to fourth embodiments as a program selection (or data selection) connector.
3 except that the connector 16 (see FIG. 1) is used instead of the connector 3, and the other points are the same as in the first to fourth embodiments.

The connector 16 has a structure similar to that of the connector 23. The male side is fixed on the board 12 and five connection pins are provided upright, and each connection pin is connected to the board 1.
