DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a controller for an electrolytic cell, a purifier using sterilized water, and a toilet purifier.

[0002]

2. Description of the Related Art The applicant of the present invention has previously disclosed in Patent Application No.
-56712.

[0003] The electrodes of such an electrolytic cell are inconsistent with the problem that the electrolytic water generation ability is reduced due to scale adhesion when current is repeatedly applied with the same polarity, and the electrode is rapidly degraded when the polarity is frequently switched. Had one problem.

Therefore, conventionally, it is premised that the energization is repeated with the same polarity, and for example, the polarity is switched when the number of repetitions reaches 15 times.

[0005] In addition, a constant current control for maintaining a constant current flowing between the electrodes is usually performed on the electrodes of such an electrolytic cell so that the electrolytic water generation ability is constant.

[0006]

However, for example, if a power failure occurs at the time of 14 repetitions, the polarity is switched after repeating the operation 29 times before and after the recovery from the power failure. Disinfection water supply was to be performed in a significantly reduced state. In such a state, for example, there has been a problem that the degree of dirt on the toilet becomes worse than usual.

If the efficiency of energizing the electrodes of the electrolytic cell deteriorates due to scale adhesion or electrode deterioration, the applied voltage must be increased to obtain a constant current, and the output power eventually reaches the rated power. Thus, there has been a problem that the power supply to the electrodes of the electrolytic cell has become unusable.

It is a first object of the present invention to provide an electrolytic cell in which the electrolytic water generation capacity does not decrease even when a power failure occurs,
A second object is to provide an electrolytic cell that can be used continuously even after the power output of the electrolytic cell reaches the maximum capacity.

[0009]

SUMMARY OF THE INVENTION The present invention relates to a control apparatus for an electrolytic cell in which electrodes comprising an anode side and a cathode side are arranged, and an electric current is generated between the electrodes to generate electrolyzed water. When the electrolyzed water generation ability, which is gradually reduced by repeating energization of the electrodes, decreases to a predetermined capacity, a polarity switching means for switching the polarity between the anode side and the cathode side, and a nonvolatile memory for storing a value indicating the electrolyzed water generation ability After recovering from a power failure, the current electrolyzed water generation capacity can be determined by referring to the non-volatile memory. This eliminates the problem that the polarity is not easily switched.

In a preferred embodiment of the present invention, the electrolytic cell can be configured to generate sterilized water for cleaning the device to be purified.

Further, when the device to be cleaned is a toilet device, the problem that the polarity is not easily switched even when the toilet is very dirty can be solved.

According to the present invention, there is further provided an electrolyzer control apparatus for arranging electrodes comprising an anode side and a cathode side and generating electrolyzed water by energizing between the electrodes. Constant current control means for controlling the power supply voltage so as to keep the power supply voltage at a predetermined value; constant power control means for controlling the power supply voltage so as to maintain the output power of the power supply at a predetermined value; When it becomes impossible to maintain the predetermined value, the current supply cannot be maintained at the predetermined value by providing the power supply control means for operating the constant power control means. Can be used.

As a preferred embodiment, when the output power of the power supply reaches a predetermined value determined by the rated power of the power supply, the constant power control means can be operated.

When the power supply voltage reaches a predetermined value determined by the rated voltage of the power supply after the operation of the constant power control means, the constant power control means for maintaining the power supply voltage at the predetermined value is operated to thereby provide a constant power supply. Even in a state in which the control current cannot be controlled and the energizing current is greatly reduced and the electrolytic water generation ability is further reduced, the electrolyzing tank is continuously operated until the energizing current is reduced to a predetermined value determined by the minimum current that can generate electrolyzed water. It can be used.

According to a preferred embodiment, at least one of an energizing current, an output power, a power supply voltage, and whether or not a constant power control means or a constant voltage control means is activated is notified to reduce the electrolytic water generation capacity. It is easy to ascertain whether the factor is caused by a decrease in the energizing current or another factor.

In the case where the electrolytic cell produces sterilizing water for cleaning the device to be purified, sterilizing water can be continuously supplied even if the sterilizing water is reduced in capacity. It is easy to grasp the factors.

Further, when the device to be purified is a toilet device, the antifouling effect of the toilet can be continuously obtained even if the sterilizing ability is reduced, and it is easy to grasp the cause when the antifouling effect is reduced.

That is, for example, after the constant current control cannot be performed until the maintenance is rushed to replace the electrodes, the toilet bowl can have a more or less antifouling effect.

Further, as a further embodiment, after the constant voltage control means is operated, the power supply from the power supply to the electrodes is stopped.
Even when the electrolytic cell does not generate electrolyzed water, by supplying tap water to the toilet through the electrolytic cell that does not generate electrolyzed water, until maintenance rushes instead of replacing the electrode, Although it is washing with water, the antifouling effect of the toilet can be obtained to some extent.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall structural view of a toilet purifying apparatus according to an embodiment of the present invention, wherein a urinal 1 and a water supply pipe 2 are connected via an on-off valve 3. The urinal 1 is provided with a reservoir 5 for shutting off bad smell and the like from the drain pipe 4, and the on-off valve 3 is controlled to open and close by a toilet automatic cleaning system 6.

The automatic toilet flushing system 6 includes a human body detecting device such as an infrared ray (not shown). When a person leaves the urinal 1, the on-off valve 3 is opened and water is passed through the urinal 1. After elapse, the on-off valve 3 is closed.

In this embodiment, there is further provided a bypass pipe 7 which branches off from the water supply pipe 2 upstream of the on-off valve 3 and joins the water supply pipe 2 downstream of the on-off valve 3. Upstream opening / closing valve 8, electrolytic cell 9, liquid reservoir 1
0, a pressure feed pump 11 and a downstream opening / closing valve 12 are provided.

The electrolytic cell 9 has a pair of electrodes (not shown).
By supplying electricity to the electrodes, tap water passing between the electrodes is electrolyzed to generate free chlorine-containing water.

The liquid reservoir 10 stores the liquid that has passed through the electrolytic cell 9 and is formed by an open-to-air tank, and detects that the liquid level has reached a predetermined high water level (HL). And a lower float SW 10b for detecting that the liquid level has dropped to a predetermined low water level (LL).

The pressure pump 11 is provided for sending the liquid stored in the reservoir 10 to the urinal 1 via the bypass pipe 7 on the downstream side.

Further, a control device 13 for controlling each load provided in the bypass pipe 7 is provided. The control device 13 opens the upstream opening / closing valve 8 and performs electrolysis by a predetermined trigger signal. When the tank 9 is energized to generate free chlorine-containing water, and the free chlorine-containing water is stored in the reservoir 10 to a predetermined high water level (HL), the upstream-side on-off valve 8 is closed and the water is supplied to the electrolytic tank 9. Stop energization.

After that, the control device 13 starts the downstream side on-off valve 1
2 is opened and the pressure pump 11 is driven to supply the free chlorine-containing water stored in the reservoir 10 to the urinal 1, and then the liquid level in the reservoir 10 is lowered to a predetermined low water level (LL). When it drops, the downstream side on-off valve 12 is closed and the pressure feed pump 11 is stopped.

The free chlorine-containing water supplied to the urinal 1 in this manner not only sterilizes and cleans the inner wall surface of the urinal 1 but also prevents the propagation of various bacteria by being stored in the storage section 5.

Next, this embodiment will be described with reference to a plurality of urinals 1a to 1
2 is shown in FIG. 2, and only the differences from FIG. 1 will be described.

That is, the bypass pipe 7 downstream of the pressure feed pump 11 branches into branch pipes 7a to 7c, and the branch pipes 7a to 7c are connected to the urinals 1a to 1c through the downstream opening / closing valves 12a to 12c. 1c.

In FIG. 2, for convenience of explanation, the on-off valve 3 controlled by the automatic toilet flushing system 6 and the water supply pipe 2 in which the on-off valve 3 is installed are not shown.

Next, FIG. 3 shows this embodiment in which a plurality of urinals 1 are used.
It is an external view of the form applied to a-1c.

That is, the panel 1 installed in the toilet
4 urinals 1a to 1c are arranged on the front,
The control device 13 is configured by the control boards arranged on the back surface of the control device 4.

The control device 13 is provided on the front of the panel 14.
The operation confirmation SW 15 connected to the
At a position corresponding to the control board, a display section 16 composed of 7-segment LEDs is arranged.

The control performed by the controller 13 in the toilet cleaning apparatus having the above configuration will be described in detail with reference to time charts shown in FIGS.

First, an operation for filling the inside of the bypass pipes 7a to 7c with tap water will be described with reference to FIG.

[Tap Water Storage Operation] That is, at a predetermined scheduled time, the upstream opening / closing valve 8 is opened, and the storage in the liquid reservoir 10 is started. Since no power is supplied to the reservoir 10, tap water is stored in the reservoir 10.

When the upper float SW 10a detects that the liquid level in the liquid reservoir 10 has reached 4.35 liters, the upstream opening / closing valve 8 is closed after the delay time tx (1 sec) has elapsed to store the liquid. finish.

Here, the delay time tx is equal to the sump 1
Due to the temporary undulation in 0, the upper float SW 10a
Is provided so that the upstream-side on-off valve 8 does not repeatedly open and close even if it is repeatedly turned on and off in a short time.

[Tap Water Release Operation] Subsequently, one second after the closing of the upstream-side on-off valve 8, the downstream-side on-off valve 12c corresponding to the farthest urinal 1c is opened, and the delay time t2
After a lapse of (500 msec), the pressure feed pump 11 is driven to start discharging from the liquid reservoir 10 to the bypass pipe 7c.

Here, the delay time t2 corresponds to the pressure of the pressure pump 11 relative to the downstream opening / closing valve 12c that is not completely opened.
This is provided to prevent the pressure from being applied.

When the lower float SW 10b detects that the liquid level of the liquid reservoir 10 has dropped to 0.35 liters by turning off the lower float SW 10b, the pump 11 is stopped after the delay time t3 (1 sec) has elapsed and the downstream pump 100 msec later. The side opening / closing valve 12c is closed.

Here, the reason why the delay time t3 is provided is to prevent the pumping pump 11 from repeating the driving / stopping in a short time as in the case of the delay time tx. This is for closing the downstream opening / closing valve 12c after the discharge pressure of the pressure feed pump 11 completely disappears, similarly to t2.

[Repetition of tap water storage / discharge operation] One second after closing the downstream opening / closing valve 12c, the upstream opening / closing valve 8 is opened again, and the above storage / discharge operation is performed on the bypass pipes 7b and 7a. It repeats and ends the operation.

At the end of the above operation, the dead water in the bypass pipes 7a to 7c can be replaced by filling the entirety of the bypass pipes 7a to 7c with tap water.

Next, an operation for cleaning the urinals 1a to 1c with sterilizing water and storing the sterilizing water in traps 5a to 5c (not shown) of each urinal will be described with reference to FIG.

[Sterile Water Storage / Electrification Operation] That is, 10 seconds after the above operation is completed, the power supply to the electrode of the electrolytic cell 9 is started, and 100 msec later, the upstream opening / closing valve 8 is turned on.
10 msec after that, the PWM control for the voltage applied to the electrode is started, and the storage of the sterilizing water in the reservoir 10 is started.

Here, the reason why the power supply to the electrodes is energized in advance is that the PWM control can be started immediately when the upstream opening / closing valve 8 is opened.

The PWM control is for keeping the concentration of the water containing free chlorine constant, and by changing the pulse width output from the controller 13 to adjust the voltage applied to the electrodes, Is kept constant.

When the upper float SW 10a detects that the liquid level in the reservoir 10 has reached 4.35 liters, the delay time tx (1 sec) elapses, the PWM control is terminated, and the upstream opening / closing valve is opened. 8 is closed, and the storage of the sterilizing water is completed.

After 10 msec, the power supply to the electrodes is terminated, and after 10 msec, the electrodes are short-circuited to start discharging the accumulated charges of the electrodes.

Here, the delay time tx is used not only to prevent the upstream side on-off valve 8 from repeatedly opening and closing in a short time, but also to prevent the start / end and discharge of the electrode from being repeated in a short time. It is provided.

The discharge of the accumulated electric charge of the electrode due to the short-circuit between the electrodes prevents the scale from adhering to the electrode.

[Sterilized Water Release Operation] Subsequently, one second after the closing of the upstream-side on-off valve 8, the downstream-side on-off valve 12c corresponding to the furthest urinal 1c is opened. Tap water discharge operation], and closes the downstream open / close valve 12c to end the operation.

At the end of the above operation, the common part of the bypass pipes 7a to 7c is filled with sterile water,
The staying tap water in this common area can be replaced.

[Sterile Water Storage / Electrification / Discharge Operation Repeated]
10 seconds after closing the downstream on-off valve 12c.
Thereafter, the discharge due to the short-circuit between the electrodes is terminated, and the power supply to the electrodes is started. After 10 msec, the upstream side on-off valve 8 is opened again and the PWM control is started. The operation is repeated 3 × 2 times from 7a to 7c, and the operation is completed.

Here, by performing the discharge due to the short circuit between the electrodes in the seventh operation for 20 seconds longer than the discharge up to the sixth operation, it is possible to surely prevent the scale from adhering to the electrodes.

At the end of the above operation, the urinals 1a to 1a
1c is washed with sterilizing water, and sterilizing water is stored in the traps 5a to 5c of each urinal.

In this embodiment, the scheduled time is 3
It is set twice, hour and 22:00. Because urinal is used immediately after the above-mentioned series of sterilizing water purification operations,
Since the sterilizing water is wasted and undesired, it is better to perform the above-mentioned sterilizing water purification operation when the frequency of use of the urinal is low. It is often installed in a non-residential building where there is hardly any residence, and if you set the working hours from 8:00 to 17:00, you have a margin before and after, and from 22:00 to 3:00, the time when the toilet is not used This is because even if you look at it, you can't really go wrong.

Then, by the sterilizing water purification operation at 22:00, it is possible to quickly cope with the dirt caused by the use of the toilet, and by the sterilizing water purification operation at 3:00, the dirt due to the use of the toilet after that is prevented. is there.

Next, the power supply circuit of the electrolytic cell 9 will be described with reference to FIG.
This will be described with reference to FIG.

That is, on the secondary side of the transformer 101,
An anode and a cathode of the electrolytic cell 9 (not shown) are connected via a polarity switching section 102 including resistors R1 and R2 for voltage detection, a resistor R3 for current detection, a relay, and the like.
The primary side is configured to rectify AC 100V and supply DC stabilized power, and a power control unit 10 including a D / D converter for changing the DC power supply voltage.
3 is provided.

The voltage detected by the voltage detecting resistors R1 and R2 and the current detected by the current detecting resistor R3 are determined by the controller 10
4 and the controller 104 calculates a PWM signal for power control based on these detected values,
By providing the same PWM signal to the power control unit 103,
The DC power supply voltage on the secondary side of the transformer 101 is changed.

The controller 104 also includes a polarity switching unit 102
The polarity switching unit 102 is configured to send a polarity signal indicating whether the polarity is forward or reverse. When the power is turned on, the polarity of the anode and cathode of the electrolytic cell 9 is initialized in the forward direction. The polarity is switched in the forward and reverse directions according to the polarity signal.

As described above, the controller 104 controls the electrolytic cell 9
For the power supply circuit of the function of switching the polarity of the electrode,
It has a function of changing the DC power supply voltage. Of these, the function of switching the polarity of the electrodes will be described with reference to the flowchart shown in FIG.

First, polarity data is read from a non-volatile memory (not shown) (S1). Based on the data, the polarity direction and the number of applications in the same direction are recognized, and a polarity signal in the recognized direction is sent to the polarity switching unit 102. (S2).

Subsequently, the falling edge of the electrolytic cell energization shown in FIG. 5 is checked (S3), and if there is a falling edge, the number of times of application in the same direction is counted up (S3).
4).

Then, it is confirmed whether or not the number of times of application of the same polarity has reached the predetermined value K (S5), and if so, the polarity direction is switched (S6) and the count value of the number of times of application of the same direction is reset (S7). ), The polarity direction and the number of applications in the same direction are stored as polarity data in the nonvolatile memory (S8), and the process returns to step S1.

On the other hand, if the same polarity application frequency has not reached the predetermined value K, the process proceeds to step S8.

Here, the predetermined value K is the maximum number of times that does not substantially affect the sterilizing water generating ability even if the electrolytic water generating ability is reduced due to scale adhesion due to repetition of the same polarity.

Next, the function of the controller 104 for changing the DC power supply voltage will be described with reference to FIG.

First, it is confirmed whether there is a request for energizing the electrodes (S101). If there is no request, initial setting is made to the constant current mode (S102). If there is, the power is turned on (S10).
3) Check whether the current mode is in the constant current mode (S104).

In the constant current mode, it is checked whether the detected current value is equal to the target value 1.5A (S105). If not, the magnitude relationship between the detected current value and the target value 1.5A is determined (S105).
106), the above-described PWM signal is adjusted so that the detected current value becomes equal to the target value 1.5A, and the inter-electrode current value of the electrolytic cell 9 is changed (S107, S108).

Here, the target value 1.5 A is a value determined by the target concentration of the free chlorine-containing water generated between the electrodes, and is maintained constant by adjusting the power supply voltage as shown in FIG. It has become so.

Returning to step S105, when the detected current value becomes equal to the target value 1.5A, it is checked whether the detected voltage has exceeded 30V (S109), and if so, the PWM signal is adjusted so that the detected voltage becomes 30V. Is changed to reduce the inter-electrode current value (S110), and the mode shifts to the constant power mode (S111).

Here, the state in which the detected voltage exceeds 30 V is a state in which the output power has reached the maximum power supply output of 45 W given that the target current value is 1.5 A.
It is not desirable to increase the power any more. Therefore, the constant current control, which is increasing the output power, is terminated, and the operation shifts to the constant power control as shown in FIG.

The reason for such a state is that the scale adheres to the electrode or the electrode itself is deteriorated.
This is because the inter-electrode resistance increases, and the power supply voltage must be increased in order to maintain the inter-electrode current.

Returning to step S104, if it is not in the constant current mode, it is checked whether it is in the constant power mode (S11).
2).

In the constant power mode, first, it is checked whether the detected voltage does not exceed the maximum power supply voltage of 35 V (S11).
3) If it does not exceed, the output power calculated from the detected current and the detected voltage is compared with 45 W of the maximum output of the power supply (S114), and the PWM signal is changed so that the output power becomes 45 W, and the distance between the electrodes is changed. The current is reduced (S115).

On the other hand, when the detected voltage exceeds the maximum power supply voltage of 35 V, the PW is adjusted so that the detected voltage becomes 35 V.
The M signal is changed to reduce the current between the electrodes (S11
6) The mode is shifted to the constant voltage mode (S117).

Returning to step S112, if it is not in the constant power mode, the detected voltage is compared with the maximum power supply voltage of 35V (S118), and the PWM is adjusted so that the detected voltage becomes 35V.
By changing the signal, the current between the electrodes is reduced (S11).
9).

Thereafter, when the detected current becomes 0.7 A or less (S120), "OE" which is a code indicating the electrode life is displayed on the display unit 16 (S121), and when the detected current becomes 0.5A or less. (S122), the energization itself to the electrodes is terminated (S123).

As described above, the inter-electrode current, which was initially maintained at 1.5 A by the constant current control as shown in FIG. 9, becomes more frequent as the frequency of use increases and the inter-electrode resistance increases.
Since it becomes impossible to maintain 1.5 A, as shown in FIG.

Further, as the frequency of use increases and the resistance between the electrodes increases, it becomes impossible to maintain a constant power in the circuit, so that the operation shifts to the constant voltage control as shown in FIG.

During the constant power control and the constant voltage control,
Although the concentration of free chlorine-containing water will not reach the target concentration,
Nevertheless, it has a germicidal effect to some extent, so that it continues to be used.

[0086] However, the detected current is 0.5% at which the generated free chlorine-containing water does not substantially exhibit a bactericidal effect.
When the voltage drops to A, the electrodes are not energized to prevent waste of power. However, at a stage of the detection current 0.7 A before that, the user is prompted to replace the electrodes via the display unit. It is.

Even if the detection current is reduced to 0.5 A and the electrode is not energized, the control shown in FIG. 5 should be continued.

This is because even if it does not have a sterilizing effect, it is possible to exert some antifouling effect on the urinal 1 only by washing with tap water.

The control device 13 of the present embodiment further has a function of displaying the above-described detected current and detected voltage on the display unit 16. This will be described with reference to FIG.

First, the display section 16 displays A to D (not shown).
It is assumed that these four switches are used for other display functions such as time setting, for example, and that a two-second timer is set in step S1 (S20).
1) It is confirmed whether both the A and B SWs are simultaneously pressed and continue for 2 seconds (S202 to S204).

If this is continued, after setting the 2 second timer again (S205), it is confirmed whether the state where both the A and B SWs are simultaneously pressed is shifted to the state where only the BSW is being pressed and continued for 2 seconds (S205). S206 to S208).

If this is continued, it is checked whether the state where only the BSW is pressed is shifted to the state where both the BC and SW are simultaneously pressed (S209, S210). When this is confirmed, for example, "10" indicating a detection voltage of 10V is displayed. Is displayed on the display unit 16 (S211).

Then, after confirming that all the switches are not pressed (S212), a 5-second timer is set (S21).
3) If the DSW is not pressed continuously for 5 seconds, the display of the voltage or current on the display 16 is terminated (S2).
14 to S216).

On the other hand, if the DSW is pressed within 5 seconds, if the voltage is currently being displayed, for example, "15" indicating the detected current 1.5A is displayed on the display section 16, and if the current is being displayed, The display is returned to the voltage display (S217 to S219).

As described above, the SW provided in the display unit 16
With the operation described above, the detected current / detected voltage shown in FIG. 6 can be displayed on the display unit 16, and the operator compares the visually detected detected current / detected voltage value with the state shown in FIG. It can be estimated without actually measuring the concentration of water containing free chlorine.

If the concentration of the free chlorine-containing water can be estimated, if the toilet is dirty, it can be determined whether or not the cause is caused by a decrease in the concentration of the free chlorine-containing water. If the toilet is dirty in spite of this, measures can be taken to look for other causes.

[0097] Not only the detected current and the detected voltage, but also the output power, the power supply voltage, and whether or not the constant power control means or the constant voltage control means are operated are displayed on the display unit 16 in the same manner. Needless to say, the effect is obtained.
