Abstract
A salt water chlorinator () for a swimming pool includes an electrolysis cell having two anodes () and a cathode (). Two scrapers (), each of which is of titanium and includes scraping portions in the form of ribs () in contact with the opposite surfaces of the cathode, are reciprocated relative to the cathode () to remove scale deposits from the cathode (). The scrapers () are mounted in a frame () and their scraping ribs () are curved such that the ribs () are self-biased against the cathode surfaces. A mechanism for reciprocating the scrapers () includes two solenoid coils () which act on cores () in a stem () of the frame (). A control circuit for the electrolysis cell is contained in a housing () which is attached to a housing () for the electrolysis cell. The control circuit includes a flow sensor for sensing salt-water flow through the electrolysis cell.
