Title: Electrolytic water producing device
Inventor: AKIYAMA FUMIKI
IPC: C02F1/46
Filed: 1997-12-15
Abstract: PROBLEM TO BE SOLVED: To provide an electrolytic water producing device provided with a means for performing such reverse voltage treatment that while the deterioration of electrodes is restrained to the utmost, scale formed on the electrode surface can be surely removed. SOLUTION: After a process wherein voltage of positive potential is applied to a pair of electrode plates 22 to perform water electrolysis is finished, a control device 30 starts an electrode short-circuit circuit 28. In this way, positive and negative charges remaining on the electrode plates 22 are cancelled by each other to lower the voltage between the electrode plates 22. After the voltage is thus lowered, when the control device 30 starts a power circuit 24 and a polarity reversal circuit 26, voltage between the electrode plates 22 is quickly reversed. In such a way, a voltage reversal process for removing scale is effectively carried out in a short time.
