Abstract

A blow dryer has a housing elongated along an axis and formed with a relatively large head and a slender handle. A two-part centrifugal fan having a hollow interior is mounted in the head and is driven by a motor mounted in the handle. A heater is provided inside the hollow fan. Rotation of the fan by the motor therefore draws air axially in at both ends of the housing, passes the air over the heater inside the fan, and expells the air laterally from the housing.
