Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolytic ion water generator for electrolyzing tap water or the like to continuously generate alkaline ion water and acidic water.

[0002]

2. Description of the Related Art In order to continuously generate electrolytic ionic water,
Supplying drinking water such as tap water in a closed electrolytic cell, energizing a direct current voltage between the negative and positive electrodes in the electrolytic cell, electrolyzing the supplied drinking water and containing a lot of cations collected on the cathode side Drinking water and cosmetic water containing anions that collect on the anode side are obtained. When electrolytic ionized water is continuously used in this way, impurities (scale) will be deposited and deposited on the cathode surface when the amount of water used in the water conditioner increases, which gradually increases the electrolysis capacity of drinking water. There is a drawback to decrease. It is known that the polarity of the DC voltage applied to the electrodes is reversed in order to remove the scale attached to the electrode plate by this electrolysis. That is, the scale attached to the electrode is eluted by the reversal of the conduction polarity. Using this principle, conventionally, a switch is manually operated to reverse the polarity of the applied voltage between the electrodes for washing for a predetermined time, or when the cumulative time of water supply reaches a predetermined value, the applied voltage between the electrodes is changed. There has been proposed a device in which the polarity is reversed and automatic cleaning is performed. However, in the case of manual control, when the electrolytic capacity is reduced due to the scale adhering to the electrodes, the backwash time for returning the electrolytic capacity to the initial state cannot be optimally controlled. If the polarity is reversed and the washing is performed at the end of the process in which the electrolytic ability is lowered, it takes a long time to remove the scale by dissolution.
Various materials are used for the electrodes, but elution and consumption occur when backwashing takes a long time. Further, in the latter case where automatic cleaning is performed by the cumulative time of water supply, the cumulative time is not necessarily proportional to the size of the amount of water used, and therefore, it cannot be said that the timing for cleaning by reversing the polarity can be set optimally. Therefore, if the cleaning time is short with respect to the amount of scale attached to the electrode, the electrolytic ability is not sufficiently restored, and if the cleaning time is too long, the electrode is consumed.

[0003]

SUMMARY OF THE INVENTION In view of such a point, the present invention detects the optimum time for cleaning by reversing the polarity, and restores the electrolysis capacity to the original state so that it is always constant. It is an object of the present invention to enable continuous treatment while maintaining the optimum state, and to shorten the backwash time to extend the life of the electrode.

[0004]

A control circuit for adding a switching signal to the polarity switcher each time the integrated quantity of electrolysis current flowing between the electrodes of an electrolysis cell reaches a set value is provided at an optimal time when the electrolysis capacity decreases. It is characterized in that cleaning is repeated by switching the energizing polarity.

[0005]

As described above, according to the present invention, the cleaning is performed by switching the energizing polarity each time the integrated electric quantity of the electrolysis current reaches the set value. Since the accumulated amount of electricity is accumulated in proportion to the accumulated amount of electricity, it is possible to accurately detect the amount of scale accumulated by measuring the amount of electricity. Therefore, by cleaning each time the accumulated amount of electricity reaches the set value It is possible to maintain a constant optimum state at all times and continuously and stably generate ionized water. In addition, by setting the set value of the integrated amount of electricity to the required value, it is possible to control the cleaning polarity when cleaning by reversing the current polarity each time, and thereby reducing the elution consumption of the electrode. Prolongs the service life and enables long-term continuous use.

Reference numeral 9 denotes a polarity switch for the DC output of the rectifier 5, which normally switches to the a contact shown in the figure and switches to the b contact when the relay coil is excited.

Reference numeral 10 is a control circuit for supplying a switching signal to the polarity switching device 9, which integrates the electric quantity of the electrolytic current detected by the ammeter 11 inserted in the power supply circuit, and when it reaches the set value, the switching signal. Is configured to output. For integrating the amount of electricity, for example, the detection signal of the ammeter 11 is converted into a digital pulse and the converted pulse is counted by a counting circuit.
By adding the analog signal of the ammeter 11 to the integrating motor and integrating the number of rotations of the motor, the electric quantity can be detected and measured.

Numeral 12 is a timer circuit for switching the energizing polarity by the switching device 9 and setting a cleaning time when the electrode 1a, 1b is energized in the opposite polarity for cleaning. The timer circuit is operated by the output switching signal of the control circuit 10. Then, when the set time is completed, a reset signal is output to the switch 9. Reference numeral 13 is a flip-flop that is inverted by the signals of the control circuit 10 and the timer circuit 12, and controls the output by adding it to the switch 9.

In the figure, 14 is a switch for switching the set value of the electric quantity of the control circuit 10, and 15 is a timer circuit 12.

Reference numerals 16 and 17 denote light emitting diodes, and 16 indicates light emission when electrolytic ionized water is generated by a reset signal of the flip-flop 13, and 17 operates a switching device 9 by a set signal to reverse the energization polarity to indicate that the cleaning process is being performed. indicate. Reference numeral 18 denotes a switching device that switches the secondary side voltage of the transformer 4 to adjust the energization voltage.

In the above, when the power supply switch 3 is turned on to cause the power supply display diode 7 to emit light and then water is supplied to the electrolytic cell 1 by opening the tap of the water supply, the water supply switch 8 is turned on by the detection of the water supply sensor. Power supply to the electrolytic cell 1 starts. The switch 9 is in contact with the contact a while the excitation control is not performed, and an electrolytic current flows between the negative and positive anodes 1a and 1b with the polarity shown in the figure, and the drinking water supplied into the electrolytic cell 1 is electrolyzed. Thus, alkaline ionized water containing a large amount of cations is obtained on the cathode 1a side, and acidic ionized water containing a large amount of anions is obtained on the anode 1b side. Alkaline ionized water can be used for beverages, and acidic ionized water can be used for cosmetics.

While the electrolytic ion water is being generated, the light emitting diode 16 emits light to indicate that electrolysis is in progress. The electrolytic current flowing from the power source to the electrolytic cell 1 is measured by the ammeter 11 and integrated by the control circuit 10. Continuous electrolysis is continued until the accumulated amount of electricity reaches the value set by the switch 14, but when the amount of electricity reaches the set value, a polarity switching signal is output and the flip-flop 13 is set to set the signal. In addition to the polarity switch 9, the energization polarity is switched to perform reverse polarity energization between the in-tank electrodes 1a and 1b. When the reverse polarity is applied, the light emitting diode 16 disappears, and the light emitting diode 17 emits light to indicate that backwashing is in progress.

This reverse polarity energization removes the scale deposited and deposited on the electrodes 1a, 1b during the generation of electrolytic ionized water, and at the same time, sterilization treatment in the electrolytic cell 1 is performed.
The switching signal output from the control circuit 10 is also added to the timer circuit 12, and the cleaning time can be set by operating the timer. This time setting is set by the switch 15, and the optimum time required for removing the scale attached to the electrode can be set. When the set time is completed, a reset signal is output from the timer circuit 12, the flip-flop 13 is reset, the signal to the polarity switch 9 is cut off, the switching contact is switched to the a contact, and the electrolytic ion water is generated again. To do. At this time, the light emitting diode 17 disappears and the diode 16 emits light to indicate that electrolysis is in progress. In addition, the reset signal is applied to the control circuit 10 to clear the accumulated amount of electricity, and the accumulated amount of electrolytic current is accumulated from the beginning.

When the switch 8 is turned off by stopping the water supply, the electrolysis current to the electrolyzer 1 is cut off and the current measurement by the ammeter 11 is interrupted, but the integrated electric quantity of the control circuit 10 does not turn off the power switch 3. As long as the water supply switch 8 is turned on again, the amount of electricity is added to the previously held integrated value, and the polarity switching signal is always subjected to predetermined electrolysis so that the scale or the like adheres to the predetermined amount. Sometimes cleaning is performed by applying reverse polarity electricity, and the electrode 1a,
Prevents elution and consumption of 1b.

Generally, in the electrolytic treatment of tap water in the suburbs of Tokyo, when the electrolytic current density is treated at 2 A / dm ² , a constant backwash of 30 seconds is performed every time electrolysis is performed for about 10 minutes. It is possible to stably generate electrolytic ionized water. The electrolyzed water is proportional to the product of the flowing current and time, that is, the accumulated amount of electricity that has been energized. Therefore, the amount of scale attached to the electrolytic electrode is also proportional to the amount of electricity. As a result, by adding backwashing every predetermined value, backwashing can always be performed at the optimum time, and the scale can be easily and completely removed in a set short time.By repeating this backwashing, stable electrolysis capacity can be obtained. It can be maintained to perform electrolytic ion water production.

The present invention has been described with reference to one embodiment, but the electrolytic current is not detected by an ammeter, but the electrolytic current flows in proportion to the conductivity of drinking water or other water to be supplied. By measuring the electric conductivity and the specific resistance, the amount of electricity can be detected, integrated, and a backwash signal can be output.

[0018]

As described above, according to the present invention, the accumulated electric quantity of the electrolysis current is used as a signal for switching the energizing polarity and cleaning is performed. Therefore, the scale of the electrode adhesion deposited and deposited by the electrolytic action is the electric quantity of the electrolysis current. Since the amount of scale that adheres can be accurately detected by measuring the amount of electricity, the electrolytic capacity is always kept constant by cleaning each time the accumulated amount of electricity reaches the set value. Maintaining the best condition, it is possible to continuously and stably generate electrolytic ionized water. Also, by selecting the set value of the integrated quantity of electricity to the required optimum value, it is possible to control the cleaning time at the time of cleaning by reversing the energization polarity each time to the minimum, thereby reducing the elution consumption of the electrode. It has a long service life and can be used continuously for a long time.
