In the late 19th century, the washing machine took its first steps as a semi-automatic mechanical device.. These machines were mostly purely mechanical, powered by hand, belt or, later, rudimentary electric motors..
In 1851, American James King invented and patented the first washing machine using a rotating drum.. The drum was partially filled with water. Seven years later, in 1858, another American named Hamilton Smith built and patented the first washing machine with a rotating drum.. Historians claim that these machines were the first modern washing machines. In 1861, the ability to soak clothes Washing machines added.
Clothes were placed in a metal or wooden tub and washed by vanes, oscillating arms, or a simple drum.. The reciprocating or rotating movement caused mechanical agitation in the water and soap; A process that separates dirt from fibers.
In 1874, William Blackstone, an American businessman, built a machine that would remove dirt from clothes and wash them as a birthday present for his wife.. This device consisted of a wooden tub in which there was a flat piece of wood containing six small wooden pegs. Dirty clothes were hung on wooden pegs and spun in hot soapy water.. Not long after, Blackstone began manufacturing and selling this $2.50 device.
This physical principle is the same concept that is known today as Agitation. Draining water and draining was completely manual and to get the water from the clothes from pressure rollers. (Wringer) was used; Two cylinders between which clothes were passed to remove excess water. Although this part was simple, it was dangerous in terms of safety and later led to the design of safer systems.
In 1907 AD, Alva J. Fisher first Electric washing machine invented in the United States. This machine was called the Thor and was sold by the Hurley Machine Company in Chicago. The said machine was accompanied by a drum, and the blades lifted and washed the clothes by rotating the drum..
As Thor revolutionized the laundry business, other companies focused on consumer markets. Among these companies was Maytag, which started with the production of agricultural tools; But gradually he introduced the wooden washing machine in 1907. In 1911 AD, another famous company called Whirlpool started producing a machine with a rotating drum and an electric motor..
From the point of view EngineeringThese machines were an example of replacing human energy with simple mechanical mechanisms. There was no temperature control, automatic timing, or high-powered motors yet, but these designs were groundbreaking Washing machines They modernized and showed how Engineering It can gradually transform daily tasks.
