Fig.13.8 - Exploded view of Bonnet type Hair dryer
The exploded view of Bonnet type Hair dryer is shown in Fig.13.8 below.
Motor driven fan: The fan should probably be called a blower; the blade is shaped like the
impeller on a vaccum cleaner and mounted in a housing which is connetcted to the outlet duct.
Most motors are of single speed, shaded pole motors particularly in the smaller models. Some
of the larger and more eleborate types have multiple speed motors or solid state control units on
Universal motor. Early hair dryers put out only about 100 watts of heat. But nowadays hair
dryers producing up to about 2,000 watts are available, drying hair considerably faster.The motors
will be designed to work on 230 V, 1-phase, 50 Hz AC supply. The small black fan sits atop the
motor as shown in Fig 13.9. The motor spins the fan. Air is drawn in through the openings on the
side of the hair dryer.
