Abstract
A method and apparatus for treating an oxygen containing gas (generally air) and/or water in an appliance such as a refrigerator washing machine, dryer or dishwasher with ozone so as to disinfect the water used within the appliance and use the ozone in the air to disinfect the interior space and the contents of the appliance. Arrangements may be made to provide disinfected water on demand. The ozone containing gas is provided when needed, or in the case of a refrigerator, at a time of the day when the refrigerator is not generally in use. The generator may include a source of ultraviolet radiation, a plenum for the air and a plenum for the water. The plenum for the water may be in the form of a tube which is transparent to ultraviolet. The diameter of the tube is preferably selected so that plug flow of water through the tube occurs. The ozone containing air and the disinfected water may be provided to a location remote from the appliance.
