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. Working of Electric Iron

8. There are basically two types of electric irons: 1) Automatic 2) Non-Automatic Types of electric irons

9. Sole Plate Pressure Plate The Heating Element Thermostat The Cover Plate Handle Pilot Lamp Main parts of an electric iron

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.  Sole Plate

11. Pressure Plate 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. The Heating Element

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. Thermostat

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.
