Abstract: A tumbler is provided for removing odors, such as smoke, from clothing. The tumbler comprises a rotating basket in which clothing tumbles, a blower which causes air to flow through said basket and an ozone source which releases ozone into the air which flows into the basket. The tumbler includes a controller which activates the ozone source after the basket and blower have been activated; and continues to operate the blower and basket after deactivation of the ozone source to provide for a purge period.

Abstract: A clothes dryer is provided with a fire detection and suppression system which releases a fire suppressing substance into the dryer chamber upon detection of a fire condition. The fire detection and suppression system includes, a controller, at least one temperature detector which is in communication with the controller and sends a signal to the controller when a temperature set point has been reached and/or exceeded, a source of fire suppressing substance (preferably water) which is delivered to the chamber over a pathway; and a valve in the pathway controlled by the controller. The controller opens the valve when a fire condition is detected, and closes the valve after a time sufficient to introduce a predetermined volume of the fire suppressing substance has passed.

Abstract: An arrangement for drying material in a selected drying location by a heated and flowing drying stream wherein the temperature and relative humidity levels of the drying stream are sensed upstream and downstream of such selected drying location and are relatively and comparatively controlled to arrive at a selected treated material moisture with comparatively minimal energy input.
