Abstract
In a batch type electrolyzed water producing method, a first run of electrolysis is carried out, and electrolyzed water is discharged. Thereafter, before a next run of electrolysis is carried out, the polarity of a DC power source connected to the electrode plates is reversed. Thus, the electrode plate which has served as a cathode plate in the last run of electrolysis is converted into an anode plate and therefore, deposits accumulated on the electrode plate are ionized and dissolved into the subject water.
Claims6
A method of producing electrolyzed water comprising the steps of:
- filling at least two electrolyzing chambers with subject water to be electrolyzed;
- connecting an electrode plate provided in one of said electrolyzing chambers to an anode, and connecting an electrode plate provided in the other of said electrolyzing chambers to a cathode;
- applying a voltage to said subject water and producing electrolyzed water in said electrolyzing chambers;
- indicating whether said electrolyzed water produced in each of the electrolyzing chambers is electrolyzed acidic water or electrolyzed alkaline water;
- discharging said electrolyzed water out of said electrolyzing chambers;
- filling the electrolyzing chambers with new subject water to be electrolyzed;
- connecting said electrode plate provided in the one of said electrolyzing chambers to the cathode, and connecting said electrode plate provided in the other of said electrolyzing chambers to the anode;
- and
- applying a voltage to said new subject water and producing electrolyzed water in said electrolyzing chambers.
An apparatus for producing electrolyzed water comprising:
- an electrolytic cell having a first electrode plate to which one of an anode and a cathode is connected a second electrode plate to which the other of the anode and the cathode is connected, and a membrane provided between said first electrode plate and said second electrode plate to define at least two electrolyzing chambers;
- inlet ports through which subject water is introduced into said electrolyzing chambers;
- outlet ports provided in said electrolyzing chambers, respectively, through which electrolyzed water is discharged;
- valves provided in said outlet ports, respectively;
- a polarity reversing circuit for reversing the polarity of said anode and said cathode connected to said first and second electrode plates;
- and
- indicators for indicating whether said electrolyzed water discharged through each of said outlet ports is electrolyzed acidic water or electrolyzed alkaline water.
