Abstract

PROBLEM TO BE SOLVED: To provide an electrolytic water generator capable of generating electrolytic water with high accuracy by preventing the generation of electrolytic water with lower accuracy caused by power failure even when power is interrupted during the electrolytic water generation process.

After the electrolytic water generation operation is discontinued, in the absence of a power-failure detection by the power-failure detection means, the electrolytic water generation operation is started over again. Thereby, electrolytic water generating operation with high accuracy can be executed without being affected by fluctuations in power source and voltage due to power failure.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolyzed water generator, and more particularly to electrolytic treatment when a power failure occurs.

[0002]

2. Description of the Related Art In recent years, an electrolyzed water producing apparatus has been known which enhances a cleaning effect by producing electrolyzed water containing acidic components and electrolyzed metal ions by electrolyzing.
As an example, a method for producing alkaline water having a bactericidal activity against hypochlorous acid or hypochlorite ion and an electrolyzer (Japanese Patent Application Laid-Open No. 2-212058)
000-93964), or a sterilizing device for a toilet and a sterilizing method for a toilet by mixing silver ions having bactericidal properties into cleaning water by performing electrolysis using a silver electrode plate as an electrode (Japanese Patent Laid-Open No. 20-200200).
01-90145) and the like are known. In these electrolyzed water generators, washing water having a desired ion concentration or pH concentration can be obtained by performing appropriate electrolysis.
It is possible to perform effective cleaning. However, if the accuracy of electrolysis is low, for example, if the concentration of generated ions is low, the desired sterilization effect cannot be obtained.On the contrary, if the concentration of ions is high, the deterioration of the electrode will be rapid, and the ions will crystallize. There are problems such as blackening. Therefore,
In order to perform effective cleaning, it is necessary to generate electrolyzed water by an accurate electrolysis operation.

[0003]

However, in the conventional electrolyzed water generating apparatus, even if a power failure occurs during the electrolyzed water generating operation, the control microcomputer can supply power in the range of 1.8V to 5.5V, for example. Therefore, if the control microcomputer does not reset the power supply and there is an instantaneous power failure, the electrolyzed water generation operation was continued. However, the accuracy of the electrolysis operation becomes unstable because the voltage supplied to the energizing means for energizing the electrolytic cell to generate the electrolyzed water and the reference voltage in the measuring means such as AD conversion of the microcomputer become unstable due to the power failure. However, there is a possibility that the effect of sterilization and the like expected in the original electrolytic water cleaning cannot be fully exerted.

FIG. 2 shows a block diagram of an automatic urinal cleaning device including the configuration of the electrolyzed water generating device shown in FIG. Here, the circuit of the automatic urinal cleaning device is divided into a power supply board and a control board. The power supply board generates a DC voltage for driving the urinal automatic cleaning device from AC100V. First,
A voltage for driving the solenoid valve is generated by smoothing AC100V by the filter unit, and a DC voltage for driving the electrolytic cell power supply unit and the control microcomputer is generated by the transformer from the smoothed voltage.

It has a sensing distance adjustment VR for adjusting the sensing distance and W.

Next, FIG. 3 shows a circuit diagram of the power failure detecting means. The power failure detection means applies the AC voltage extracted by the transformer to generate a 12V DC voltage to the transistor to generate a zero-cross signal. That is, if the voltage applied to the transistor is near 0V, the transistor becomes non-active and the zero-cross signal becomes 5V. If the voltage applied to the transistor is not near 0V, the transistor becomes active and the zero-cross signal becomes 0V. In the power failure detection means, the power supply voltage is 10
Since the half-wave of 0V is taken out, if the power supply voltage is normal, it will be 0V every 20ms in the 50Hz region.
In the Hz region, it becomes 0V every about 16.7 ms. If a power failure occurs, the zero-cross signal remains 0V or 5V. Here, in the detection of the occurrence of a power failure by the power failure detection means of the present embodiment, a zero-cross signal is extracted from the power supply voltage and input to the control microcomputer, and the zero-cross signal is changed from 5V to 0.
If the switching edge that switches to V is detected, it is determined that the power supply voltage is being supplied normally, and the zero-cross signal is 45 ms.
If 0V or 5V is continuously maintained as described above, it is determined that a power failure has occurred. Detecting the switching edge of the zero-cross signal from 5V to 0V in the state of power failure, then
If the state where the switching edge of the zero-cross signal is not input again for 45 ms or more does not occur during 1 s, it is determined that the power supply voltage has recovered from the power failure and is operating normally.

A circuit diagram of the energizing means is shown in FIG. The energizing means receives a voltage of 30V generated from the power supply voltage, and turns on / off the transistor by switching the output of 5V and 0V from the control microcomputer to generate a current for energizing the electrolytic layer. Moreover, in the energizing means shown in FIG.
The direction of the electric current when the electric current is applied to the electrolytic cell can be switched by the relay switching A / B output from the control microcomputer.

In the first specific example, the operation of the urinal automatic cleaning device that performs an electrolyzed water generating operation by applying a predetermined amount of current to the electrolytic cell will be described.

First, in order to understand the electrolyzed water producing operation (hereinafter referred to as electrolyzing operation) of the urinal automatic cleaning apparatus of the specific example 1, a conventional electrolyzing operation without detecting a power failure will be described with reference to the flowchart of FIG. explain.

In step S1, it is determined whether or not the state of the automatic urinal cleaning device is in the electrolytic operation. If the state of the automatic urinal cleaning device is in the electrolysis operation, the process proceeds to S2 to check whether the time from the start of the electrolysis operation is T1 or more. If the time from the start of the electrolysis operation is less than T1, the water supply operation is continued, and the process is terminated. If the time from the start of the electrolysis operation is T1 or more, the process proceeds to S3 to end the water supply.
Next, in S4, it is confirmed whether the time from the end of water supply is T2 or more. If the time from the end of the water supply is less than T2, the energizing operation is continued, and the process is terminated. If the time from the end of water supply is T2 or more, the process proceeds to S5 to end the energization. In S6, the state of the automatic urinal cleaning device is switched to the stopped state, and the electrolyzed water generating operation is ended.

In S1, if the state of the automatic urinal cleaning device is not in the electrolysis operation, the process proceeds to S7, and it is determined whether it is the timing for starting the electrolysis operation. Here, in the automatic urinal cleaning device, the start of the electrolytic operation is determined depending on the usage status of the urinal and the passage of time. If the electrolysis operation start timing is not reached in S7, the stopped state is maintained.
Leave the process as it is. If it is the electrolysis operation start timing in S7, the process proceeds to S8, and the water supply means is brought into the water supply state to start the water supply to the electrolytic cell. Then, in S9, the energization control means starts energization of the energization means to the electrolytic cell.
At this time, a current having a predetermined magnitude is applied to the electrolytic cell. As a result, electrolyzed water is generated and the urinal is washed. Proceeding to S10, the state of the automatic urinal cleaning device is switched to the electrolytic operation, and the process ends.

A timing chart of the above operation is shown in FIG. FIG. 6 shows the state of water supply by the water supply means, the state of energization by the energization means, and the state of the zero-cross signal extracted from the power supply voltage. T1 is the water supply time during the electrolysis operation, and T2 is the energization time after the end of the water supply during the electrolysis operation.

Next, as a specific example 1, in a urinal automatic cleaning device that performs an electrolyzed water generating operation by supplying a predetermined amount of current to an electrolytic cell, an operation when a power failure is detected by a power failure detecting means Will be described with reference to the flowchart of FIG. 7.

In step S1, it is determined whether the automatic urinal cleaning device is in the electrolytic operation. If the state of the automatic urinal cleaning device is in the electrolytic operation, the process proceeds to S2 to check whether a power failure has occurred. If a power outage has occurred, the process proceeds to S3 to terminate energization, and proceeds to S4 to terminate water supply. Next, in S5, the state of the automatic urinal cleaning device is switched to the power outage stopped state, and in S6, 1 is added to the number of times of power outage detection, and the process ends.

If no power failure has occurred in S2,
In S7, it is confirmed whether the time from the start of the electrolysis operation is T1 or more. If the time from the start of the electrolysis operation is less than T1, the water supply operation is continued, and the process is terminated. If the time from the start of the electrolysis operation is T1 or more, the process proceeds to S8 to end the water supply. Next, in S9, it is confirmed whether the time from the end of water supply is T2 or more. If the time from the end of the water supply is less than T2, the energizing operation is continued, and the process is terminated. If the time from the end of the water supply is T2 or more, the process proceeds to S10 to end the energization, and the state of the automatic urinal cleaning device is switched to the normal stop state in S11. In S12, the number of power failure detections is reset to 0, and the process ends.

In S1, if the state of the automatic urinal cleaning device is not in the electrolytic operation, the process proceeds to S13, and it is confirmed whether or not the power outage is stopped. If the power outage is stopped, the process proceeds to S14 and it is confirmed whether or not the power outage is not detected. If no power failure is detected, the process proceeds to S15, and it is confirmed whether the power failure recovery confirmation 1s timer is 0 or not. If the power failure recovery confirmation 1s timer is 0, the process proceeds to S16, and it is confirmed that the number of power failure detections is 2 or less. If the number of times of power failure detection is 3 or more, it is considered that the power source is abnormal and the electrolysis operation is not started even after the power failure is restored. Therefore, the processing directly ends. If the number of times of power failure detection is 2 or less, the state of the automatic urinal cleaning device is switched to the normal stop state in S17, and the process is exited. If the power failure non-detection confirmation 1s timer is not 0 in S15, the power failure is still stopped, and the process is exited. If a power failure is detected in S14, the process proceeds to S18, the power failure non-detection confirmation 1s timer is updated, and the process is exited.

In S13, if the power failure is not stopped, S
In step 19, it is determined whether it is time to start the electrolysis operation. Here, in the automatic urinal cleaning device, the start of the electrolytic operation is determined depending on the usage status of the urinal and the passage of time. If it is the timing for starting the electrolysis operation, the process proceeds to S20, and the water supply control means sets the water supply means of the water channel to the water supply state and starts the water supply to the electrolytic cell. Then, in S21, the energization control means starts energization of the electrolysis tank of the energization means. At this time, a current having a predetermined magnitude is applied to the electrolytic cell. As a result, electrolyzed water is generated and the urinal is washed. Proceeding to S22, the state of the automatic urinal cleaning device is switched to the electrolytic operation, and the process is exited. In S19, if it is not the start timing of the electrolysis operation, the normal stop state is continued, and therefore the process is directly terminated.

In the urinal automatic cleaning device of the first embodiment,
The timing chart of FIG. 8 shows the operation of the urinal automatic cleaning device when one power failure is detected during electrolysis, and the timing chart of FIG. 9 shows the operation when three power failures are detected during electrolysis. . Each timing chart shows the state of water supply by the water supply unit, the state of energization by the energization unit, and the state of the zero-cross signal extracted from the power supply voltage. T1 is the water supply time during the electrolysis operation, and T2 is the energization time after the end of the water supply during the electrolysis operation. As shown in FIG. 9, when the power failure detecting means repeatedly detects the power failure and the detection of the power failure during the electrolysis operation, when the power failure is detected twice or less, the electrolytic water generation operation is started by the power failure recovery. After the second power failure is detected, the electrolytic water generation operation does not start even after the power failure is restored. A timing chart of the above operation is shown in FIG. In FIG.

As described above, when a power failure occurs during the electrolyzed water producing operation of the electrolyzed water producing apparatus, the electrolyzing operation is temporarily stopped so that the power supply section is affected by the power failure. Prevents inaccurate electrolyzed water generation operation, and performs electrolytic cleaning again after recovery from a power failure, so that the power supply section is not affected by the power outage, etc. It becomes possible to do.

Further, when a power failure occurs in the power supply unit during the electrolytic water generating operation, the power consumption is large during the electrolytic water generating operation, so that there is a high possibility that the voltage will suddenly drop and the microcomputer will be reset. In a device such as the urinal automatic cleaning device which is an embodiment of the present invention, which is premised on continuous operation, it is desirable that the resetting of the microcomputer should not occur as much as possible. In the present invention, the power consumption can be reduced by stopping the electrolyzed water generation operation when a power failure occurs. Therefore, the possibility of resetting the microcomputer can be reduced by slowing the voltage drop. It will be possible.

In Example 2, the electric conductivity of water flowing through the electrolytic cell is measured, and the measured electric conductivity is used to determine the magnitude of the current flowing through the electrolytic cell to generate electrolytic water. The operation of the cleaning device will be described.

First, in order to understand the electrolyzed water producing operation of the automatic urinal cleaning device of the second specific example, the electrolyzing operation without detecting a power failure will be described with reference to the flowchart of FIG.

In step S1, it is determined whether or not the state of the automatic urinal cleaning device is in the electrolytic operation. If the state of the automatic urinal cleaning device is in the electrolytic operation, the process proceeds to S2, and it is confirmed whether the preliminary cleaning is being performed. If pre-cleaning is in progress, it is confirmed whether the time from the start of pre-cleaning is T11. T
If it is 11, the process proceeds to S4, the energization is started, and the process ends. In S3, if the time from the start of the preliminary cleaning is not T11, the process proceeds to S5, and the time from the start of the preliminary cleaning is T12.
Check whether or not If it is T12, proceed to S6,
Measure the voltage and current of the electrolytic cell. Next, in S7, the energization is terminated, and in S8, the energizing current amount for generating electrolyzed water is calculated using the voltage and current of the electrolytic cell measured in S6, and the process is terminated. If the time from the start of the preliminary cleaning is not T12 in S5, the process proceeds to S9 to check whether the time from the start of the preliminary cleaning is T1 or more. If the time from the start of the pre-cleaning is less than T1, the water supply operation is continued, and the process is terminated. If the time from the start of the preliminary cleaning is T1 or more, the process proceeds to S10 to end the water supply, and in S11, the state of the urinal automatic cleaning device is switched to the standby state and the process is exited.

In S2, if the state of the automatic urinal cleaning device is not preliminary cleaning, the process proceeds to S12, and it is confirmed whether or not the state of the automatic urinal cleaning device is on standby. If it is on standby, the process proceeds to S13, and it is confirmed whether the time from the start of standby is T2 or more. If the time from the start of standby is T2 or more, the process proceeds to S14 to start water supply, and proceeds to S15 to start energizing the current amount obtained in S8. At S16, the state of the automatic urinal cleaning device is switched to the electrolytic operation, and the process is terminated. If the time from the start of waiting is less than T2 in S13, the process is terminated.

In S12, if the state of the automatic urinal cleaning device is not in the standby state, the process proceeds to S17, and it is confirmed whether the time from the start of the electrolysis operation is T3 or more. If the time from the start of the electrolysis operation is less than T3, the water supply is not finished and the process is terminated. If it is T3 or more, the process proceeds to S18, and the water supply is ended. Further, the process proceeds to S19, and it is confirmed whether or not the time from the end of the water supply is T4 or more. If it is less than T4, the energization is not ended and the process is ended. If the time from the start of the electrolysis operation is T4 or more, the process proceeds to S20 to end the energization, and in S21, the state of the automatic urinal cleaning device is switched to the stopped state, and the process ends.

In S1, if the state of the automatic urinal cleaning device is stopped, the process proceeds to S22, in which it is determined whether it is the timing for starting the electrolysis operation. Here, in the automatic urinal cleaning device, the start of the electrolytic operation is determined depending on the usage status of the urinal and the passage of time. If it is the start timing of the electrolysis operation, the process proceeds to S23, and the water supply control means sets the water supply means of the water channel to the water supply state and starts the water supply to the electrolytic cell. Then, the process proceeds to S24, and the state of the automatic urinal cleaning device is switched to pre-cleaning. In S22, if it is not the start timing of the electrolysis operation, the stopped state is continued, and the process is ended.

A timing chart of the above operation is shown in FIG.
Shown in. FIG. 11 shows the state of water supply by the water supply means, the state of energization by the energization means, and the state of the zero-cross signal extracted from the power supply voltage. T1 is the water supply time during the pre-cleaning, T11 is the time from the start of the water supply during the pre-cleaning to the start of energization, and T12 is the energization time during the pre-cleaning. T2 is the standby time, T3 is the water supply time during the electrolytic operation, and T4 is the energization time after the end of the water supply.

Next, as a second specific example, the operation of the automatic urinal cleaning device for detecting a power failure by the power failure detecting means will be described with reference to the flowchart of FIG.

At S1, it is determined whether the urinal automatic cleaning device is in the electrolysis operation or is stopped. If the automatic urinal cleaning device is in the electrolysis operation, the process proceeds to S2 to check whether a power failure is detected. If a power failure is detected, the process proceeds to S3 to end the energization, and proceeds to S4 to end the water supply. Next, in S5, the state of the automatic urinal cleaning device at the time of the power failure is stored as a power failure state, and in S6, the state of the automatic urinal cleaning device is switched to the power outage stopped state. Next, in S7, 1 is added to the number of times of power failure detection, and the process is exited.

In S9, if the time from the start of the preliminary cleaning is not T11, the process proceeds to S11, and it is confirmed whether or not the time from the start of the preliminary cleaning is T12. If it is T12, the process proceeds to S12, the voltage and current of the electrolytic cell are measured, and the energization is terminated in S13. From the voltage and current of the electrolytic cell measured in S14, the amount of current passed through the electrolytic cell during the electrolysis operation is calculated, and the process is terminated. If the time from the start of the preliminary cleaning / cleaning is not T12 in S11, the process proceeds to S15, and it is confirmed whether or not the time from the start of the preliminary cleaning is T1 or more. If the time from the start of the pre-cleaning is less than T1, the pre-cleaning is continued, and the process is terminated. If the time from the start of the preliminary cleaning is T1 or more, the process proceeds to S16 to end the water supply, and S1
At 7, the state of the automatic urinal cleaning device is switched to the standby state and the processing is exited.

In S8, if the state of the automatic urinal cleaning device is not pre-cleaning, the process proceeds to S18 to check whether the state of the automatic urinal cleaning device is in standby. If it is in the standby state, the process proceeds to S19 and it is confirmed whether or not the time from the start of the standby period is T2 or more. If the time from the start of standby is T2 or more, the process proceeds to S20 to start water supply, and proceeds to S21 to start energization. Next, in S22, the state of the automatic urinal cleaning device is switched to the electrolytic operation, and the process is terminated. S19
If the time from the start of standby is less than T2, the standby is continued, and the process is exited.

In S18, if the state of the automatic urinal cleaning device is not in the standby state, the process proceeds to S23 and it is confirmed whether the time from the start of the electrolysis operation is T3 or more. If the time from the start of the electrolysis operation is less than T3, the electrolysis operation is continued, and the process is terminated. Time from the start of electrolysis operation is T
If it is 3 or more, the process proceeds to S24 to end the water supply. S25
If the time from the end of the water supply is T4 or more, the process proceeds to S26 to end the energization. In S27, the state of the automatic urinal cleaning device is switched to the normal stop state, and in S28, the number of power failure detections is cleared to 0, and the process ends. If the time from the end of the water supply is less than T4 in S25, the energization is continued and the process ends.

In S1, if the state of the automatic urinal cleaning device is not in the electrolytic operation, the process proceeds to S29 to check whether the power outage is stopped. If the power failure is being stopped, the process proceeds to S30 to check whether the power failure detecting means is detecting the power failure. If a power failure is being detected, the process proceeds to S31 to update the power failure recovery confirmation 1s timer and exit the processing. If no power failure is detected, S32
Proceed to and confirm whether the power failure recovery confirmation 1s timer is 0 or not. If the power failure recovery confirmation 1s timer is 0, the recovery from the power failure is confirmed, so the process proceeds to S33, and it is confirmed whether the number of power failure detections is 2 or less. If the number of times of power failure detection is 3 or more, the process proceeds to S34 and the sensing LED is used to notify the abnormality.
Blink to exit the process. If the number of power failure detections is 2 or less in S33, the process proceeds to S35.

In S35, it is confirmed whether or not the power failure state is the preliminary cleaning. If the power failure state is in the preliminary cleaning, the process proceeds to S36 to switch the state of the automatic urinal cleaning device to the preliminary cleaning and exit the process. If the power failure state is not in preliminary cleaning, the process proceeds to S37 to check whether the power failure state is waiting. If the power failure state is in standby, the process proceeds to S38 to switch the state of the automatic urinal cleaning device to standby and exit the process. If the power failure state is not standby, the process proceeds to S39 to check whether the power failure state is the electrolytic operation.
If the power failure state is during the electrolytic operation, the process proceeds to S40 to switch the state of the automatic urinal cleaning device to the electrolytic operation and exit the process. If the power failure state is not the electrolytic operation, the process proceeds to S41 to switch the state of the automatic urinal cleaning device to the normal stop state and exit the process.

If the state of the automatic urinal cleaning device is not in the power outage stop state in S29, the process proceeds to S42 to check whether it is the electrolysis operation start timing. If it is the electrolysis operation start timing, the process proceeds to S43 to start water supply, and proceeds to S44 to switch the state to the pre-cleaning and exit the process. If it is not the timing to start generation of electrolyzed water in S42, the stopped state is continued and the process is exited.

The timing chart of FIG. 13 shows the operation of the urinal automatic cleaning device when a power failure is detected during the preliminary cleaning.
FIG. 14 shows the operation of the automatic urinal cleaning device when a power failure is detected during the electrolysis operation. 13 and 14 show the state of water supply by the water supply means, the state of energization by the energization means, and the state of the zero-cross signal extracted from the power supply voltage. In this way, when a power failure is detected during the preliminary cleaning, the accuracy of measuring the electric conductivity of water is unreliable, so when the power is restored, the preliminary cleaning is performed again to measure the electric conductivity of the water. If a power failure is detected during the electrolysis operation, you can trust the measurement result of the electric conductivity in the preliminary cleaning, but there is a possibility that the current supplied to the electrolytic cell for generating electrolyzed water contains an error. When the power is restored, the urinals are cleaned by performing only the electrolytic operation without pre-cleaning.

Also, a power failure is detected during standby, and then
If the standby time has not expired even after the power is restored, the automatic urinal cleaning device remains in standby, and the electrolysis operation starts when the standby time ends. However, if the standby time ends when the power is restored, the electrolysis operation is started when the power is restored.

Next, the timing chart of FIG. 15 shows the operation of the automatic urinal cleaning device when three power failures are detected between the start of preliminary cleaning and the end of electrolytic operation. FIG. 15 shows the state of water supply by the water supply means, the state of energization by the energization means, the zero-cross signal extracted from the power supply voltage, and the state of the sensing LED. If three or more power failures are detected between the start of pre-cleaning and the end of electrolytic operation, it is determined that an abnormality has occurred in the power supply, and pre-cleaning or electrolytic operation is not performed even after the power failure is restored. To inform.

As described above, when the power failure occurs during the preliminary cleaning, the preliminary cleaning is temporarily stopped to measure the inaccurate electrical conductivity in the state where the power failure is affected by the power failure. By performing the preliminary cleaning again after the recovery from the power failure, it is possible to perform the accurate operation of measuring the electric conductivity without being affected by the power supply section due to the power failure. As a result, it becomes possible to perform cleaning with electrolyzed water with high accuracy using the accurately measured electrical conductivity.

Further, when a power failure occurs during the electrolysis operation after the completion of the pre-cleaning, the electrolysis operation is temporarily stopped, and electrolysis water with low accuracy due to the energization operation in a state where the power supply section is affected by the power failure. It is possible to prevent generation operation and perform electrolytic cleaning again after recovery from power failure to perform highly accurate electrolyzed water generation operation by energizing operation without being affected by the power supply etc. due to power failure.
