Method of producing electrolyzed water

A method of producing electrolyzed water containing ozone by using an apparatus for producing electrolyzed water from a liquid;

• the apparatus comprising:
• an electrolytic cell;
• an inlet for allowing a liquid forced into the cell to flow through;
• a first electrode plate placed in the cell;
• a second electrode plate placed in the cell and facing the first electrode plate;
• a direct current power source for applying a direct current voltage to the first and second electrode plates so as to produce a potential difference therebetween;
• a control circuit for changing a polarity of the electrode plates alternately;
• and
• an outlet through which electrolyzed water produced in the cell is let out of the cell;
• wherein:
• the first electrode plate and the second electrode plate are mutually spaced apart to define a clearance of no greater than about 3.0 mm therebetween and define a flow passage extending therealong, and
• an interval of time T for changing the polarity of the electrode plates can be set between about 0.5 and 60 seconds;
• the method comprising a first step, a second step and a third step,
• in the first step, introducing the liquid from the inlet into the flow passage,
• in the second step, applying the direct current voltage across the two plates by the direct current power source and alternately changing the polarity of the two electrode plates at the interval of time T by the control circuit to produce electrolyzed water while the liquid is flowing through the flow passage, and
• in the third step, the electrolyzed water being let out of the outlet,
• the first, second and third steps being simultaneously and continuously executed.

• the apparatus comprising:
• an electrolytic cell;
• an inlet means for allowing a liquid forced into the cell to flow through;
• a first electrode plate placed in the cell;

• a direct current power source for applying a direct current voltage to the first and second electrode plates so as to produce a potential difference therebetween;
• a control circuit for changing a polarity of the electrode plates alternately;
• and
• an outlet pipe through which electrolyzed water produced in the cell is let out of the cell;
• wherein:
• the first electrode plate is close to the second electrode plate and the two plates define a clearance of 3.0 mm or less between them and define a flow passage extending along them, and
• each of the electrode plates having non-perforated and perforated portions appearing alternately in the direction of flow of the liquid, the non-perforated portions of one of the electrode plates facing the perforated portions of the other;
• the method comprising the step of introducing the liquid from the inlet means into the flow passage to let out the electrolyzed water from the outlet pipe.

A method of producing electrolyzed water containing ozone, comprising:

• arranging first and second plate electrodes to face each other and being spaced apart from one another to define a flow passage therebetween extending therealong;
• introducing a liquid into the flow passage;
• applying a direct current voltage across the first and second plate electrodes;
• and
• alternately changing a respective polarity of the first and second plate electrodes back and forth at an interval of time effective for producing electrolyzed water containing ozone while the liquid is flowing through the flow passage.
