Abstract: An appliance for drying or warming associated laundry items includes a housing having a wall forming a stationary cavity dimensioned to receive the associated laundry items. At least one article support member is preferably contained within the cavity. A heater increases a temperature of associated air within the cavity and a fan circulates the heated air within the cavity. A vent is dimensioned to allow air to exit the housing cavity, and a controller regulates circulation of the associated heated air within the cavity.

Abstract: An ozone detection system includes a source of sample gas containing a concentration of ozone and a single optical pathway. The system includes a light source in optical communication with the optical pathway. The system further includes a first airflow passageway for receiving a first sample of gas from the source. The passageway includes a catalytic scrubber to reduce ozone content in the sample gas and passing the reduced ozone gas to a sensor. The system further includes a second airflow passageway for receiving a second sample of gas from the source and passing the gas unaltered to a sensor. The system further includes a sensor for sensing independently the light intensity of the sample of gas received from the first and second passageways. The system further includes a processor for receiving the light intensity data from the sensor and calculating the ozone concentration in the source of sample gas.
