Abstract
Abstract An apparatus for providing an aqueous sterilizing and deodorizing solution to equipment which is to be kept sanitary. The apparatus has means for confining a supply of tap water, said means having a tap water inlet and a solution outlet adapted to be connected to the equipment to be kept sanitary. An electrolytic cell is positioned in said confining means and has a cathode and an anode spaced from said cathode which is of a material substantially resistant to chlorine and oxygen. Current supply means supplies a D.C. current to said cell in such a way that a small reverse current flows in the cell so as to periodically make the cathode slightly anodic. This prevents buildup of calcium deposits on the cathode.

An apparatus for providing an aqueous sterilizing and deodorizing solution for a toilet which is to be kept sanitary, said apparatus comprising a toilet flush tank for confining a supply of tap water, said tank having a tap water inlet and a solution outlet adapted to be connected to the toilet, an electrolytic cell in said tank and comprising two electrodes, one of which is a perforated electrode, said electrodes being a cathode and an anode spaced from said cathode, said anode being of a material substantially resistant to chlorine and oxygen, and current supply means for supplying a current to said cell, said current supply means comprising a source of alternating current coupled across said anode and said cathode, a half wave rectifier means connected in series with said source and one of said cathode and said anode, and a shunt resisotr having a resistance at least four times the resistance of the rectifying means in the conducting direction and connected in parallel with said rectifier means, whereby when the current is reversed from the conducting direction of the rectifying means, a current no more than 25 percent of the current in the conducting direction of the rectifying means flows through thp cathode in the reverse direction making the cathode anodic and helps prevent scale formation on the cathode.
