  • Patent number: 5509852
    Abstract: A system for ventilating the cabin of an overheated vehicle which takes advantage of convection and evaporation as methods of cooling. The system is voice controlled. The invention places a fan, separate from the vehicle's air conditioning and heating system, near the rear of the cabin. The fan directly connects the interior cabin air to outside air. Upon the opening of the driver's door, the driver's window rolls down and the fan turns on, drawing hot air out of the cabin to the outside, through the rear duct and across the driver's perspiring face and body. After the temperature inside the cabin drops to a predetermined comfortable temperature, a chime sounds to alert the driver to turn the ventilating system off. Alternatively, the system may shut off automatically after a preset time period. Voice control allows the driver to winterize the system, to turn off the chime, or to run the system for demonstration purposes.
