There are many appliances which emphasis this fact and hair dryer is one among them. The following describes about hair dryer and its functions.
A hair dryer also called blow dryer is an electrical device which can be used for styling and drying the hair. Its working is much simpler and most of its mechanisms revolve around its fan. When the dryer is switched on, the electricity moves to the windings of the motor of the fan. And here the electrical energy is transformed to kinetic energy as it provides momentum to the fan and this in turn produces airflow.
As soon as the electricity is supplied, the motor begins to spin which in turn makes the fan attached to it spin. The air is pulled by the fan through the small vents on the side or the back. These inlets are known as air inlets which have a defensive screen which allows only the air to enter.
The air is blown in the direction of the heating coils. These coils are designed to get heated quickly using its electrical resistance and electric current. A coiled wire made of a poor conductor of electricity along with an insulating material is placed in its path to heat the air which becomes very hot. The coil is doesnt get corroded as well as oxidized on heating. The heating unit in the barrel gets heated by the heating coil.
Hotness of the air is controlled by a temperature switch which also controls the amount of the electrical charge that is pumped through the wire when dryer is turned on.
By using this appliance, one is able to dry and style their hair in a small amount of time. This advanced device has turned to be the womens best friend.
