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;
- a fluid pump having an impeller that rotates within a volute for delivering wash fluid to the processing space;
- and
- a nozzle coupled with the volute and the ozone generator that injects the ozone gas onto the volute to be mixed with the wash fluid that is agitated to a turbulent state in the volute.
An appliance, comprising:
- a housing;
- a tub positioned within the housing;
- a fluid inlet that receives water from a water source;
- and
- an ozone generator, wherein the ozone generator is operable between an activated state and a deactivated state, wherein the ozone generator produces ozone when in the activated state, wherein the water received at the fluid inlet is exposed to the ozone produced by the ozone generator, and wherein a hardness of the water is decreased as a result of exposure to the ozone produced by the ozone generator.
A laundry washing appliance comprising:
- a drum that is rotationally operable within a tub;
- a sanitization mechanism for delivering ozone gas into a processing space defined within the drum for sanitizing laundry within the drum;
- an ozone generator of the sanitization mechanism that generates the ozone gas, wherein the sanitization mechanism includes an ozone injector that injects the ozone gas during a specific rotational operation of the drum;
- a fluid pump having an impeller that rotates within a volute for delivering wash fluid to the processing space;
- and
- a dispenser in fluid communication with a carrier fluid supply hose and the ozone generator, wherein a one-way valve is coupled with the volute and the ozone generator that injects the ozone gas onto the volute to be mixed with the wash fluid that is agitated to a turbulent state in the volute.
