Abstract:
1. A salt water chlorinator comprising: an electrolysis cell comprising an anode and a cathode and a scraper, at least one of the cathode or the scraper being moveable relative to the other one of the cathode or the scraper along a first direction to remove deposits of electrolysis products from the surface of the cathode, wherein the scraper comprises scraping portions which are positioned and configured to be self biased against the surface of the cathode, wherein the cathode is a plate electrode and the scraper comprises opposite sides, wherein the scraping portions are in the form of ribs which extend between the opposite sides transversely to the first direction across the cathode surface, wherein the scraping portions are formed from a resilient material and in use have a curved configuration, and wherein the scraper is maintained in a position relative to the surface of the cathode such that the scraping portions resiliently contact the surface of the cathode due to the curved configuration.
