Prototype of a washing machine represented a rolled into a circle two scrub boards Today we name washing or laundry machine kind of machines to wash laundry, such as clothes. This term is mostly used only to machines that need water as opposed to dry cleaning (which applies other cleaning fluids, and is performed by industry specialists). Washing include immersing, rubbing in water and often is attended by special detergent, or just bleach.

The simplest washing machines can simply agitate clothes in water. More evolved models of automatic machines may also wash, spin, and even heat laundry in a cycle. Most contemporary machines also can delete substantial water amounts from the laundry at the final of a washing automatic cycle, and some of them can completely dry it!

But not many people know that evolution of washing machines lasted for more than 2 centuries. The earliest special-aim washing tool was… the simple scrub board, invented in 1797.

First machines were fully hand-operated and constructed from wood, whereas later machines made of iron permitted a fire to burn under the washtub, so keeping the water warm throughout the “washing cycle”. The fact: originally clothes washing technology was developed as a method to diminish the manual labor, providing an open reservoir or sealed container with special paddles or fingers that automatically agitated clothes.

By the middle of the XIX century, in the UK and US appeared first steam-driven commercial laundry machines. Technological improvements in machinery for commercial and institutional laundries proceeded faster than domestic washer technologies for several decades. In the USA there existed more emphasis on developing private machines for home washing, though machines for commercial needs were widely applied in the late XIXth and early XXth centuries. First rotary washing machine was patented by Hamilton Smith in 1858. As electricity was not usually available until the 1930s, some early washing machines were operated by a low-speed single-cylinder and even gasoline engine! Who knows how will look the future image of washing machines? May be they will do some more than modern machines with “intelligent” onboard computer and Wi-Fi connection for remote control.
