It is connected to the electric control circuit 70 so as to be measured as a measured current value I. In addition, the power source 40 described above
Is connected to the electric control circuit 70, and the output voltage can be adjusted to a predetermined voltage by a control signal from the electric control circuit 70. The power supply 40 may be a constant voltage source that constantly applies a constant voltage.

The first water supply pipe 20 is constructed so that water is pumped from an external water supply source (not shown) (not shown), and a pressure reducing valve 22 and a water valve 23 (which is an opening / closing valve) are arranged in this order from upstream to downstream. WV) and is connected to the second water supply pipe 21 connected to the electrolytic cell 10. The pressure reducing valve 22 reduces the pressure of water pumped from an external water supply source and keeps it within a predetermined pressure range. The water valve 23 is electrically connected to the electric control circuit 70 and is controlled to be opened and closed. When the water valve 23 is open (ON), water from the outside is supplied to the first and second water supply pipes 2.
It is supplied to the electrolytic cell 10 via 0 and 21.

The salt water tank 30 is separate from the apparatus main body 1 and stores concentrated salt water inside. Particularly, as shown in FIG. 2, the salt water tank 30 is connected to an electric control circuit 70.
The water level sensor S and the salt water suction pipe 32 are connected to the tank 3
0 can insert or remove from the top are found assembled in (positionable by the sliding resistance generated between the cap 31) (removable) and vertically positionable. The water level sensor S maintains an electrically connected state with the electric control circuit 70 even when it is detached.

The water level sensor S, as shown in FIG.
A filter F in which the lead wire S1 inserted through the heat-shrinkable tube 81 is integrally fixed to the outer circumference of the salt water suction pipe 32, and the detection unit S2 at the tip is attached to the tip suction port of the salt water suction pipe 32.
Arranged so that it is located a predetermined amount L above the tip opening of
Has been done . The detection unit S2 at the tip is of a well-known electrode type and detects whether or not concentrated salt water (water) is present. If the concentrated salt water is present, an "on" signal is output, and if not, "off".
Send a signal. Therefore, the water level sensor S can be positioned only by inserting the heat shrinkable tube 81 to the position where the tip of the filter F of the salt water suction pipe 32 contacts the bottom of the salt water tank 30.
It is determined, thereby making it possible to detect the predetermined level L of brine tank 30.

The salt water suction pipe 32 is connected to the input portion of the pump 33 in the apparatus body 1. The output part of the pump 33 is connected to a salt water supply pipe 34, and this salt water supply pipe 34 is connected to the second water supply pipe 21 at a position downstream of the water valve 23 of the first water supply pipe 20 via the check valve 35. To be done. The pump 33 is of an electric type, is electrically connected to the electric control circuit 70, and is configured to variably control the discharge amount . Thus, the pump 33 sucks the water in accordance with the discharge <br/> amount of a salt water tank 30 or Raso, sent to brine feed pipe 34 from the output unit, as a result, from an external water supply source to the electrolytic bath 10 dilute brine as water to be treated brine from salt water tank 30 is mixed in the water Ru is supplied through the second water supply pipe 21.

The remote controller 60 is constructed separately from the generator main body 1 and has the outlet 16 of the outlet pipes 16 and 17.
It is arranged near a and 17a. The remote controller 60 is connected to an electric control circuit 70, and a salt supply lamp (indicator lamp) 62 indicating that the salt water in the salt water tank 30 is insufficient and a pouring switch for instructing generation of electrolytic water. 61 have been found with. Salt supply lamp 62
Is controlled by receiving a display control signal from the electric control circuit 70 , and the pouring switch 61 is an operation including a start signal and an end signal for instructing each part in the apparatus main body 1 to start and end the operation of generating electrolytic water. The signal is sent to the electric control circuit 70.
Note that the pouring switch 61 electrically maintaining the on-state when pressed user once, with maintaining the electrically off-state when pressed again, can be changed to the off state electrically on-state by an electrical control circuit 70 Is configured.

This electrolyzed water producing apparatus comprises a water valve 23, a pump 33, a power source 40, a pouring switch 61,
Connected to salt replenishment lamp 62, water level sensor S and ammeter 50
The electric control circuit 70 is provided. Electric control circuit 70
Is constituted by a microcomputer, executes a program corresponding to the flowcharts (routine) for producing electrolyzed water, a program corresponding to flowcharts for lighting control salt replenishment lamp 62 for each predetermined time.

Next, the operation of the first embodiment configured as described above will be described with reference to FIGS. When the user changes the pouring switch 61 from OFF to ON in order to generate and use the electrolyzed water, the electric control circuit 70 executes the routine of FIG. 4 from step 400 at a predetermined timing, and proceeds to step 405. Monitor whether the flag F is "1". Since the electric control circuit 70 sets the electrolyzed water generation permission flag F, which will be described later, to "1" when the main power source (not shown) is turned on, "Y" is determined in step 405.
es ", the process proceeds to step 410, and it is determined whether the pouring switch 61 is changed from off to on.

At this point in time, the pouring switch 61 is just turned on, so "Yes" at step 410.
Then, the process proceeds to steps 415 to 425 to perform an operation for generating electrolyzed water. That is, in step 415, the water valve 23 is turned on to start the supply of raw water,
In step 420, the electric pump 33 is operated to start mixing salt water into the raw water. At the same time, in step 425, a constant voltage is applied to the electrodes 14 and 15 by the power supply 40, and in step 495, this routine is once ended. In this way, generation of electrolyzed water is started.

Next, the case where the user changes the pouring switch 61 from on to off in order to stop the generation of electrolyzed water will be described. The electric control circuit 70 advances the program to steps 400, 405, 410 and step 430 during the generation of the electrolyzed water to execute each step, but if the pouring switch 61 is turned off, the “ Y
es ”and step 4 to stop the generation of electrolyzed water
40 to 450 are executed. Specifically, step 440
To turn off the water valve 23 to stop the supply of raw water, and stop the operation of the pump 33 at step 445.
In step 450, the voltage application by the power supply 40 is stopped,
Stop production of electrolyzed water.

Next, the case where the salt water in the salt water tank 30 is used during the generation of the electrolyzed water and the salt water is insufficient will be described. The electric control circuit 70 also executes the lamp control routine shown in FIG. 5 every predetermined time, and in step 505 following step 500, it is determined whether or not the salt water in the salt water tank 30 is insufficient by the water level sensor. It is determined whether or not S indicates off. Therefore, when the salt water becomes low, the water level sensor S is turned off, the electric control circuit 70 makes a “No” determination at step 505 to proceed to step 520, turn on the salt replenishment lamp 62, and salt (salt water) to the user.
To replenish After that, the routine proceeds to step 525, the flag F is changed to "0", and this routine is once ended.

By changing the flag F to "0",
When the electric control circuit 70 proceeds to step 405 of FIG. 4, it is determined to be “No”, the electric connection state of the pouring switch 61 is forcibly turned off in step 435, and the above-described steps 440 to 450 are described above. Similarly, a process for stopping the generation of electrolyzed water is performed. As described above, the electric control circuit 70
Automatically stops the operation of the pump 33 and the generation of electrolytic water when the salt water in the salt water tank 30 is insufficient during the generation of electrolytic water.

The user knows that the salt water is insufficient by turning on the salt replenishment lamp 62, and performs the work of replenishing the salt water. Specifically, the water level sensor S and the salt water suction pipe 32, which are integrated by the heat-shrinkable tube 81, are pulled out from the salt water tank 30 that has run out of salt water, and replaced with another salt water tank 30 in which concentrated salt water is stored in advance. ,afterwards,
The same water level sensor S and the salt water suction pipe 32 are inserted.

When the salt water tank 30 is replaced and the water level sensor S is turned on, the electric control circuit 70 makes a "Yes" determination at step 505, and then turns off the salt replenishing lamp 62 at step 510 and proceeds to step 515. Then, in step 515, the flag F is changed to "1". As a result, the electric control circuit 70 determines “Yes” (F = 1) at step 405 in the next routine execution of FIG. However, even in this case, until the pouring switch 52 is changed from off to on, it is determined to be “No” in step 410, the determination is also “No” in step 430, and the present routine is once ended. To do. Then, when the user changes the pouring switch 61 to the on state and newly gives an instruction to generate the electrolyzed water, the electric control circuit 70 causes “Y” in step 410.
es ”, the process proceeds to steps 415 to 425, and the generation of electrolyzed water is started.

As described above, in the first embodiment, once the water level sensor S is turned off, the operation of the pump 33 and the production of electrolyzed water are stopped at that time, and
Even if the water level sensor S is turned on, the generation of electrolytic water (operation of the pump) is not restarted until the user changes the pouring switch 61 from off to on and newly instructs generation of electrolytic water (that is, operation of the pump). , Prohibition of resumption of electrolyzed water generation). Thus, during the replacement of brine tank 30 described above, the water level sensor S which is drawn from the brine tank 30 is placed on the floor surface such as a kitchen, to detect the water that is waiting reservoir on the floor, brine Even if the "on" signal equivalent to the restoration of the salt water in the tank 30 is shown, the operation of the pump 33 and the generation of the electrolyzed water are not restarted. Accordingly, inner salt suction pipe 32 that occurs when accidentally producing electrolyzed water comprising the operation of the pump 33 would resume, the air flowing into inside the pump 33 or the like, electrolytic water generation after normalization exchanged salt water tank 30 Delays can be prevented.

In the present embodiment, the salt replenishment lamp 62 is turned off at step 510 when the water level sensor is turned off after being turned off once. Even if the water level sensor S is erroneously detected, this erroneous detection is almost always the result of the user pulling out the water level sensor S from the salt water tank after starting the salt supplement work. Rather, by turning off the salt replenishing lamp 62 at that time, the user can be informed that the apparatus recognizes the work.

[0031] In the first embodiment described above,
Steps 505 and 525 of FIG. 5 and steps 405, 435, 440, 445 and 450 of FIG. 4 constitute stop means, and steps 505 and 515 of FIG. 5 and steps 405, 410, 415, 420 of FIG. Four
25 constitutes the restarting means.

Next, a second embodiment will be described with reference to FIGS. The configurational difference from the first embodiment is only that the routine of FIG. 6 is adopted instead of the routine of FIG. 5, and other points are the same as those of the first embodiment. The difference in operation from the first embodiment based on this difference is that in the first embodiment, the pump 33
After automatically stopping the operation and the generation of electrolytic water, the operation of the pump 33 and the generation of electrolytic water are restarted when "the water level sensor S is turned on and the pouring switch 61 is changed from off to on". On the other hand, in the second embodiment, “the water level sensor S is in the ON state for the first predetermined time T1 or more and the pouring switch 61 is changed from OFF to ON. In this case, the operation of the pump 33 and the generation of electrolyzed water are restarted. Furthermore,
The salt replenishment lamp 62 also says, "The water level sensor S is the first predetermined time T
It is also different from the first embodiment in that it is configured to be turned off when it is in the ON state for one or more times to prevent the life from being shortened due to frequent ON / OFF of the lamp.

Specifically, during normal operation, electrolyzed water is generated by executing the same routine as that of the first embodiment shown in FIG. At this time, since the water level sensor S is turned off when the salt water in the salt water tank 30 is low, the electric control circuit 70 determines “No” in step 605 in the routine of FIG.
In step 610, a timer T described later is cleared to "0". In the following step 615, the salt replenishment lamp 62 is turned on to indicate the lack of salt water, the flag F is reset to "0" in step 620, and this routine is once ended in step 695. After that, the electric control circuit 70
When the routine of FIG. 4 is executed, it is determined to be “No” (F = 0) in step 405, the process proceeds to step 435, the pouring switch 61 is forcibly turned off, and then the process proceeds to steps 440 to 450 described above. The operation of the pump 33 and the production of electrolyzed water are automatically stopped.

In this state, when the water level sensor S is turned on, "Yes" at step 605 in the routine of FIG.
s ”, and the timer T is set to“ 1 ”in step 625.
The value of the timer T becomes the first value in step 630.
It is determined whether or not the predetermined time T1 or more. At present, the determination in step 630 is “No”, and this routine ends in step 695 as it is. Thereafter, when the electric control circuit 70 executes the routine of FIG. 6, step 63
Until it is judged as “Yes” at 0, step 600,
The execution of steps 605, 625, 630 and 695 is repeated, the value of the timer T is increased, and the flag F is not changed (keeps "0"). Therefore, during this period, the routine of FIG. 4 executes steps 400, 405, 435, 440,
445, 450 and 495 are executed, and even if the pouring switch 61 is turned on, the operation of the pump 33 and the generation of electrolyzed water are not restarted.

After that, the timer T sets the first predetermined time T1.
In the above case, the electric control circuit 70 determines “Yes” in step 630, proceeds to step 635, turns off the salt replenishing lamp 62, and further sets flag F to “1” in step 640. With the change of the flag F to "1", the electric control circuit 70 determines "Yes" in step 405 of FIG. 4, and thereafter, it is determined whether or not the pouring switch 61 is turned on. I will monitor at 410. Then, when the user finishes the replacement work of the salt water tank 30 and changes the pouring switch 61 to ON,
Proceeding to steps 415 to 425, the operation of the pump 33 and the generation of electrolyzed water are restarted.

As described above, in the second embodiment, the flag F is set to "0" when the operation of the pump 33 and the production of electrolytic water are automatically stopped due to the water level sensor S being turned off. and ", as long as the flag F is" 0 ", eg
If, be a dispensing switch 61 is turned on, and inhibits the resumption of production of actuation and electrolytic water pump 33, the water level sensor S starts time measurement of the timer T at the time when turned on from off, When the timer T becomes the first predetermined time T1 or more, that is, "the water level sensor S has been kept in the ON state for the first predetermined time T1 or more" In the case of “higher”, the flag F is set to “1” to permit the restart of the generation of electrolytic water (and the restart of the operation of the pump 33) in the case of “the pouring switch 61 is changed from off to on”. Therefore, it is possible to more surely prevent the problem of the air entering the pump 33 and the like due to the erroneous detection of the water level sensor. In addition , turning off the salt replenishment lamp 62 causes the “water level sensor S
Is continuously turned on for the first predetermined time T1 or more ”, the water level sensor S makes unstable contact with water such as the floor surface, and repeatedly turns the lamp on and off. It is also possible to prevent the lamp life from being shortened.

In the above second embodiment, steps 605 and 620 of FIG. 6 and steps 405, 435, 440, 445 and 450 of FIG. 4 constitute stop means, and step 605 of FIG. , 610, 625,
630 and 640 and steps 405 and 41 of FIG.
0, 415, 420 and 425 constitute the resuming means.

Next, a third embodiment will be described with reference to FIGS. The configurational difference from the second embodiment is only that the routine of FIG. 7 is adopted instead of the routine of FIG. 6, and the other points are the same as those of the second embodiment. The difference in operation from the second embodiment based on this difference is that in the second embodiment, "the state in which the water level sensor S is on is the first
If it continues for a predetermined time T1 or more, ”the salt replenishment lamp 62 is turned off, and the operation of the pump 33 and the restart of the generation of the electrolyzed water are allowed (when the pouring switch 61 is turned from OFF to ON, the pump 33 While the operation and the state in which the generation of electrolyzed water is restarted are set), in the third embodiment, the "duration for which the water level sensor S is in the ON state" required to turn off the salt replenishment lamp 62, The point is that the "duration for which the water level sensor S is in the ON state" required for allowing the restart of electrolyzed water generation is different. That is, in the third embodiment, the salt supplement lamp 6
2 indicates that "the state in which the water level sensor is on is the second predetermined time T
When "2 or more continues", the light is turned off, and when "the state in which the water level sensor is on continues for the first predetermined time T1 or more", the restart of the generation of electrolyzed water is permitted.

Specifically, when the salt water in the salt water tank 30 is insufficient and the water level sensor S is turned off, the electric control circuit 70 is operated.
7 proceeds to steps 700 and 705 in the routine of FIG. 7, determines “No” in step 705, and clears the timer T to “0” in step 710. Subsequently, in step 715, the salt replenishment lamp 62 is turned on, and in step 7
The flag F is reset to "0" at 20, and the step 79
At 5, the routine ends. Therefore, the electric control circuit 70 executes step N405 at the time of executing the routine of FIG.
o ”, and in step 435, the pouring switch 61
Is forcibly turned off, and the following steps 440 and 44 are performed.
Stop production of electrolyzed water similar to the above at 5,450 (pump 3
(Including the deactivation of No. 3), the production of electrolyzed water is automatically stopped.

After that, when the water level sensor S is turned on, the electric control circuit 70 makes a "Yes" determination at step 705 of the routine of FIG. 7 and increments the value of the timer T by "1" at subsequent step 725. At this point timer T
Since the value of is smaller than the first predetermined value T1, step 73
From 0, step 735 is skipped and the process proceeds to step 740. Since the value of the timer T is smaller than the second predetermined value T2 also in step 740, the routine is finished in step 795 as it is. The first predetermined value T1 constitutes a condition for permitting resumption of generation of electrolyzed water, and the second predetermined value T2 represents a condition for turning off the salt replenishment lamp 62 for frequent on / off prevention by chattering of the salt replenishment lamp 62. Therefore, the first predetermined value T1 is set to be larger than the second predetermined value T2.

When the above-described operation is repeated and a predetermined time has elapsed, the value of the timer T becomes larger than the second predetermined value T2. Therefore, it is determined as "Yes" at step 740, and at step 745 salt supplementation is performed. The lamp 62 is turned off. However, since the flag F is still "0", the flag F in FIG.
Step 405 in the routine is determined to be “No”, and the operation of the pump 33 and the generation of electrolyzed water are not restarted.

Further, when the time elapses, the value of the timer T becomes larger than the first predetermined value T1.
