Washing machines are primarily made of sheet steel. Usually, the spin tub is made of steel with a porcelain coating. Plastic parts also constitute a small part of a washing machine assembly.Continue Reading
The scrub board was the first "washing machine" invented. They have been made of wood, corrugated metal and even plastic. They were even called "a great American invention" by the New York Times and can still be seen around in antiques shops, garage sales or laying around in your grandma's house. Interestingly, scrub boards are also used as a musical instrument. To play it, you must tap on it, and scrub occasionally.
After the scrub board, the first washing machine with a drum was invented. According to About, James King patented the machine in 1851, but it was still hand powered. Finally, in 1908, an electric washing machine was introduced. Invented by Alva J. Fisher, the Thor was a drum type washing machine that resembled the ones we see today, containing a galvanized tub and an electric motor.
The electric dryer machine was born soon after. A Frenchman named Pochon built "the ventilator", a metal drum with holes in it that was turned by hand over fire. Just like with the washboard, the dryer also became electric.Learn more about Washers & Dryers
