Abstract
A system for treating laundry with ozone including a controller that receives a load signal based on a wash load selection. The controller varies an output potential from a variable power supply to an ozone generator in response to the load signal. The ozone generator produces different levels of ozone corresponding to the output potential. A wash liquor is drawn out of a laundry machine and sent through a filter past an injector adjacent a venturi. The injector entrains ozone from the ozone generator into the wash liquor and the wash liquor is returned to the laundry machine. A method is disclosed for treating laundry with ozone by: selecting a wash load selection from a plurality of wash load selections; varying the amount of ozone provided to the injector by an ozone generator in response to the load selection; drawing a wash liquor from the laundry machine by a pump; filtering the wash liquor from the laundry machine through a filter; entraining ozone from the ozone generator into the wash liquor; and returning the wash liquor to the laundry machine.
