  • Patent number: 4972607
    Abstract: A hair-drying system for use primarily in homes and other locations which employs a central forced air blower to disperse air through an air ducting system to air terminals disposed primarily in bathrooms. The air terminals are covered over when in the non-operative position. Upon physical and electrical coupling of a hair-drying unit to the air terminal, which hair-drying unit is comprised of a dryer and a flex tubing, air will be delivered through the flex tubing to the dryer, since the flex tubing is in fluid connection with both the air ducting system and the dryer. An optional damper(s) can be employed to limit air flow. Heat is applied to the air by a dryer mounted switch controlled resistance heater. The electrical energy to operate the dryer is obtained from a grounded electrical outlet mounted adjacent the cover plate of the air terminal. If 110 volt AC is used to power the dryer, the electrical connection would be via a ground fault interrupter to prevent injury.
