An electric iron is a small appliance,a handheld piece of equipment with a flat, roughly triangular metal surface that, when heated, is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate, the fibers are stretched and the fabric maintains its new shape when cool.
The electric iron must have a design and an electric iron basically consist of basically a heating coil and thermostat. It also has electrical cord, temperature control dial and a sole plate.
·The design should allow the iron to be set down, usually standing on its end, without the hot soleplate touching anything that could be damaged. ·Thermostat : When we switch on the electric iron current flows throught the heating coil. The heat in the heating coil causes expansion in the thermostat which gradually disconnects the supply. ·Heating Coil : a coil made of metal so when electricity flows through it, it gets hot and it transferes this heat to the sole plate. ·Sole plate : it's a a flat triangular surface cast of aluminium coated with a non-stick PTFE or stainless steel. It's heated and press clothes to remove creases. ·Electrical cord: It has heat-resistant and the point at which the cord attaches to the iron has a spring to hold the cord out of the way while ironing and likewise when setting down the iron. ·Temperature control dial : allows the user to select the operating temperatures. ·Handel: to be gripped from. usaually from plastic.
The electric iron is an application of conversion of electric energy into heat energy to be used in removing creases from clothes by streching the fibers. And it consists of many parts but the most impotant are the heating coil, the thermostat and the sole plate. Electric iron is now one of the essential appliances at...
