Abstract
A tumble dryer is provided with an air closure system. The air closure system may suppress and/or conceal a fire or burning within a tumble dryer. The air closure system may include an air closure assembly including a guide mountable to a portion of the tumble dryer's ventilation system, and a shutter movably coupled to the guide. The air closure system may further include a sensor configured to complete a circuit supplying electricity to an actuator provided at the air closure assembly when the sensor senses a condition indicative of a fire or burning within the tumble dryer. In response, the actuator may release the shutter such that it closes off an opening within the guide and restricts the airflow through the ventilation system, thus suppressing and concealing the fire or burning within the tumble dryer.
