  • Patent number: 5433919
    Abstract: A method and apparatus are provided for detoxicating, aerating, drying and sterilizing clothing articles. A drying chamber is provided which has an inner chamber in which the clothing articles are to be hung. A first intermediate chamber and a second intermediate chamber are provided in the walls defining the inner chamber through which air is caused to flow. A heater is provided for heating air drawn in from the room and, if preferred, a condenser may be provided for removing moisture from the air after it has passed through the inner chamber. Air may be recirculated within the drying chamber by use of the condenser, or fresh air may flow through the condenser to provide a cooling air stream to the condenser, while heated moist air flows separately through the condenser to remove heat and moisture before the air is exhausted back into the room.
