DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment of the drawings. In FIG. 1, reference numeral 1 is an electrolytic cell, inside of which a cathode electrode 3 and an anode electrode 4 are disposed with a diaphragm 2 interposed therebetween.
Raw water is supplied from a, alkaline ionized water flows out from the discharge port 1b communicating with the upper cathode chamber, and acidic water flows out from the discharge port 1c of the anode chamber. Reference numeral 5 is a water supply sensor for detecting water pressure or water flow provided at the water supply port 1a, 6 is an AC power supply, 7 is a transformer, 8 is a rectifier, 9 is a smoothing capacitor, and a DC power supply for electrolysis having the polarity shown in the figure is constituted. Reference numeral 10 is a power switch, 11 is a switch that is turned on by a water supply detection signal of the water supply sensor 5, 12 is a polarity switcher inserted in a power supply circuit between the power supply output and the electrodes 3 and 4, and four thyristors SCR1 and SCR1.
It is configured by combining CR2, SCR3 and SCR4. The driver 13 is controlled by the control circuit 14. Reference numeral 15 is a cleaning switch.

After the power switch 10 is turned on and the faucet (not shown) is opened to supply water to the electrolytic cell 1, the switch 11 is closed by the detection of the sensor 5 and a DC voltage is applied between the electrodes 3 and 4 with the polarity shown. Electricity is supplied, water supplied is electrolyzed, and electroosmosis is performed through the diaphragm 2,
Alkaline ionized water is generated in the cathode chamber and acidic water is generated in the anode chamber, which can be discharged from the discharge ports 1b and 1c for use. If such generation of ionized water is continued, scale will be deposited and deposited mainly on the cathode electrode 3, the diaphragm 2, etc. with the passage of time. As the scale amount increases, the electrolysis capacity decreases and it becomes impossible to generate the required ionic water.

Upon detecting such a state, the start switch 15 for cleaning is turned on. The switch 15 may be controlled manually or automatically. The operation of the control circuit 14 is as follows. That is, when the switch 15 is activated, the flip-flop 1
6 is inverted and outputs "1" to the Q terminal and loads the counter 17, so that the clock of the oscillator 18 is counted. The counter 17 sets a preset value by the digital switches 20 and 21, and the set value is alternately preset through the data selector 19, and the count output is added to the flip-flop 22 to perform inversion control. When the set value by the digital switch 20 is t ₁ and the set value by 21 is t ₂ , the counter 17
Since the signals corresponding to t ₁ and t ₂ are alternately applied to the flip-flop 22 every time this value is counted, the output Q and the bar Q are alternately output “1” corresponding to t ₁ and output “equivalent to t ₂ ”. 1 "is output and a signal is applied to the driver 13 through the AND gates 23 and 24. The driver 13 turns on SCR2 and SCR3 of the changeover switch for t ₁ pulse width in response to a signal from the gate 23 to carry out reverse polarity energization with the cathode electrode 3 as the positive electrode and the anode electrode 4 as the negative electrode, and then from the gate 24. The signal causes SCR1 and SCR4 to conduct for a pulse width of t ₂ and to conduct positive polarity. Therefore, the positive and negative alternating pulse currents during the cleaning are as shown in FIG.

The output of the counter 17 is added to the other counters 25 and counted. The counter 25 is loaded by the output of the flip-flop 16, and its count value is set by the digital switch 26. If the set value is T, the output “0” is added to the flip-flop 16 to be cleared when the count value reaches T, so that the Q output which was in the holding state until now is inverted and the other flip-flop 22 And the gates 23 and 24 are closed. Therefore, the driver 13 maintains the original state of conducting SCR1 and SCR2, keeps the positive conduction, and restarts the generation of electrolytic ion water. That is, the counter 2
The set value T of 5 determines the cleaning time as shown in FIG.

When the cleaning switch 15 is turned on as described above, the cleaning work is performed for a predetermined set time T, and the cleaning is performed by reversing the conduction polarity at short intervals t ₁ and t ₂ during the period, and electrolytic cleaning is performed. Is performed by alternately switching the cathode and the anode periodically, and the operations of the cathodic electrolysis and the anodic electrolysis are repeated. Anodic electrolytic cleaning causes a strong oxidation reaction due to the generation of oxygen gas, gives a stirring action of gas, and also acts by dissolving the anode, etc. to clean, and in cathodic electrolytic cleaning, hydrogen gas is generated, and the generated amount is It is doubled and the stirring action acts violently to enhance the effect of removing scale and the like. Since the anodic electrolysis and the cathodic electrolysis act alternately and repeatedly, the cleaning effect is high, the cleaning speed is high, and the scale accumulated on the cathode electrode 3, the rust, scale, etc. adhering to the diaphragm 2 and the tank wall can be easily and quickly removed. Can be removed.

The reversal speed during cleaning is t ₁ = 5-60 s
ec, t ₂ = 0.5 to 5 sec, which is set by the digital switches 20 and 21, and the cleaning time is T = 10 sec.
It can be arbitrarily set to about 10 minutes by the digital switch 26. When the cleaning switch 15 is automatically controlled, the electrolytic ion water generation time may be controlled for a predetermined time, but a decrease in the electrolytic current may be used as a signal, or an integrated value of electrolytic current and an integrated flow rate of treated water may be signaled. Or a combination of these signals can be controlled. Further, the circuit configuration for controlling the cleaning time T of the control circuit 14 and the polarity reversal pulses t ₁ , t ₂ etc. is not limited to that of the illustrated embodiment and can be used.

[0012]

As described above, according to the present invention, the polarity switching device for switching the conduction polarity is provided in the circuit for energizing the negative and positive electrodes from the energization power source, and the polarity switching device is alternately reversed at the set time intervals during cleaning. Since the cleaning is performed by switching to, the electrolytic cleaning can be performed by alternately inverting the cathode and the anode periodically, which allows the effects of the cathodic electrolysis and the anodic electrolysis to be repeatedly given to enhance the cleaning effect. The cleaning time can be shortened and the electrolytic ability of the electrode can be completely restored. In addition, the cleaning is not limited to the electrodes, and acts on the diaphragm, the inner wall of the tank, etc. to effectively clean and remove water stains.
