Abstract
A hair dryer is provided with a hot air vent for preventing excessive rises in the air temperature of its hair-winding attachment. This vent is in addition to the air blowing holes of the hair-winding attachment for drying the hair. The dryer includes a temperature-sensitive valve for opening the hot air vent at a predetermined abnormal air temperature in the hair-winding attachment to prevent an excessive rise in temperature of the air in the hair-winding attachment which may damage the hair or the dryer body.
