Abstract
A laundry washing appliance includes a drum that is rotationally operable within a tub. A sanitization mechanism delivers ozone into a processing space defined within the drum for sanitizing laundry within the drum. An ozone generator of the sanitization mechanism generates ozone gas wherein the sanitization mechanism includes an injection device that injects the ozone into the drum during a specific rotational operation of the drum.
Claims20
A laundry washing appliance comprising:
- a drum that is rotationally operable within a tub;
- a sanitization mechanism for delivering ozone into a processing space defined within the drum for sanitizing laundry within the drum;
- an ozone generator of the sanitization mechanism that generates ozone gas wherein the sanitization mechanism includes an ozone injector that injects the ozone, in a form of the ozone gas, into the drum during a specific rotational operation of the drum;
- and
- a dispenser with a fill port in fluid communication with a carrier fluid supply hose and the ozone generator, wherein a one-way valve is opened when the ozone generator is activated to allow the ozone gas to flow through the fill port, into a tube that extends into the drum to expose articles being processed in the drum to the ozone gas.

- and
- a dispenser having a three-way valve that controls a carrier fluid being supplied from a carrier fluid supply hose, a cleaning chemistry dispensing from the dispenser, and the ozone gas being supplied by the ozone generator, wherein a one-way valve for the ozone generator is activated to allow the ozone gas to enter the drum through a tube that extends into the drum via a bellows.
