Abstract
Abstract An electrolyzed water producing apparatus according to the invention is adapted to be directly connected to a faucet of a water service to continuously producing alkali ionic water and acid ionic water by electrolyzing operation and comprises an electronic control device including an automatic-manual operation changing circuit for changing the apparatus between automatic and manual operation modes, an electric current adjusting circuit for adjusting electrolytic current dependent upon variation in water quality, and a slow start circuit for automatically delaying the time when starting supply of the electrolytic current relative to the time when starting supply of water at a commencement of operation of said apparatus in the automatic operation mode.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
144 words
An electrolyzed water producing apparatus comprising a casing; at least one electrolytic cell arranged in said casing comprising a cylindrical cathode and a cylindrical anode arranged concentrically to each other, a partition arranged between said cathode and said anode, and upper and lower caps respectively secured to upper and lower open ends of said cathode and said anode; and an electric control device, arranged in said casing comprising an automatic-manual operation changing circuit for changing said apparatus between automatic and manual operating modes, an electric current adjusting circuit for adjusting electrolytic current dependent upon variation in water quality, and a slow start circuit for delaying the supply of electrolytic current to said at least one electrolytic cell until after water has been supplied to said at least one electrolytic cell when commencing the electrolyzing operation of said apparatus in the automatic operating mode thereof.
Claim 2
Dependent Claim
144 words
An electrolyzed water producing apparatus comprising a casing; at least one electrolytic cell arranged in said casing comprising a cylindrical cathode and a cylindrical anode arranged concentrically to each other, a partition arranged between said cathode and said anode, and upper and lower caps respectively secured to upper and lower open ends of said cathode and said anode; and an electric control device, arranged in said casing comprising an automatic-manual operation changing circuit for changing said apparatus between automatic and manual operating modes, an electric current adjusting circuit for adjusting electrolytic current dependent upon variation in water quality, and a slow start circuit for delaying the supply of electrolytic current to said at least one electrolytic cell until after water has been supplied to said at least one electrolytic cell when commencing the electrolyzing operation of said apparatus in the automatic operating mode thereof.
Claim 3
Dependent Claim
79 words
An electrolyzed water producing apparatus as set forth in claim 1, wherein said cylindrical anode is in the form of a hollow cylinder provided on its inner circumferential surface with a steel plating layer and filled therein with chipped foamed material and synthetic resin material, and upper and lower ends of said hollow cylinder are covered by members made of a material which is heat-resistant and high viscous and superior in adherence and has a small thermal expansion coefficient.
