  • Patent number: 5724750
    Abstract: A rotatable drum forms an airtight seal with a door. A vacuum line connects the interior of the drum to a vacuum pump. A shutoff valve closes the vacuum line to the pump. A pressure equalization valve connects the drum to the outside atmosphere. A bearing supports the drum, in combination with the vacuum line. Infrared lamps heat clothes placed inside the drum. The vacuum pump reduces the air pressure in the drum below atmospheric pressure, reducing the evaporation temperature of the water in the clothes. A heat sensor measures the temperature of the air leaving the drum. Solenoid-driven purge valves allow air to enter the drum in short bursts, thus aiding the drying of the clothes.
