1. A system for controlling a supply of ozone for laundering clothing, the system comprising at least one washing machine comprising:
an internal drum for containing both laundry to be washed and a quantity of water; at least one ozone sampling outlet for sampling an ozone concentration of the washing machine; an ozone generator, coupled to the washing machine, for producing and supplying ozone to the water in the washing machine; an ozone exhaust sensor, coupled with the ozone sampling outlet, for sensing a concentration of ozone within the washing machine during operation of the washing machine; a controller for controlling a flow of ozone from the ozone generator to the washing machine; the controller including a temporary interrupt mechanism coupling the ozone exhaust sensor to the ozone generator, the controller being configured for:
(1) temporarily interrupting a supply of the ozone by the ozone generator to the washing machine in an event that the concentration of ozone, within the washing machine, exceeds a desired level of ozone of at least 0.1 parts per million,(2) continuing interruption of the supply of the ozone, to the washing machine, until the ozone exhaust sensor again detects that the concentration of the ozone, within the washing machine, is below the desired level; and(3) permitting further supply of ozone to the water in the washing machine so that additional ozone is supplied to the washing machine once the concentration of the ozone, within the washing machine, again falls below the desired level. |
