7. An electric Iron is a combination of heat and pressure
removes wrinkles. The principle of the electric iron is
that when current is passed through a coil, the coil gets
red hot and transfers the heat to the base plate of the
electric iron through conduction.
8. There are basically two types of electric irons:
1) Automatic
2) Non-Automatic

10. The sole plate is the thick, triangular-shaped slab of
iron that forms the base over which the electric iron is
built up. The bottom surface and edges are heavily
chromium plated, to prevent it from rusting.
11. This plate is generally
called the top plate as it
follows the shape of sole
plate. The pressure plate has
some holes through which
the studs form the base
plate passes through.
12. The heating element is present between the sole plate
and pressure plate. It is pressed hard between the two
plates. The heating element consists of nichrome wire
wound around a sheet of mica.
13. The bimetallic strip is a simple element which converts
a temperature change into mechanical
displacement.The two metals should have a different
coefficient of expansion.
14. The Cover Plate
The cover plate is made of thin sheet of iron. It is placed on top
of the base plate and it covers all the internal parts of the iron.
Handle
The handle can be made either with wood or with plastic. The
handle is attached to the cover plate with the aid of screws.
Pilot Lamp
The pilot lamp is housed in the cover plate of the electric iron.
One end of the pilot lamp is connected to supply, while the other
end is connected to the heating element.
