The first recorded evidence of a dishwasher dates back to 1850, when a patent was granted for a simple manual splash device attached to a wooden tub made by Joel Houghton. Developing this idea, L.A. Alexander added gears to a rotating rack that held dishes that allowed them to rotate inside a tub of water and this was patented in 1865. Both were very crude and made entirely of wood and didn’t really clean dishes very well. . right.
Josephine Cochrane was a wealthy woman and had engineering in her blood as her grandfather John Fitch was famous for inventing the steamboat. She also liked to frequently entertain her friends and hold social events at her house, which resulted in the need to wash many dishes each time. The crockery she used for her entertainment was expensive and her servants often broke it while doing the dishes. Tired of this, she decided to build a dishwasher that could quickly wash dishes without breaking them. She built a machine consisting of a wooden wheel lying flat in a copper cauldron that could be turned by hand or powered by a power source via a pulley. Wire frame compartments made to fit her dishes were attached to this wheel and the combination of it turning and the boiler spraying hot soapy water resulted in the first efficient dishwasher.
He brought his dishwasher to the 1893 world’s fair in Chicago, where it won the top prize and people from friends to hotel and restaurant owners lined up to order a dishwasher of their own. He quickly patented the invention and opened a production factory to build them, and this company grew into the home appliance giant known today as KitchenAid. More companies also began making other versions, some with conveyor belts and others with baskets rotated by various methods, either using a jet or a spray of hot water poured from above to wash dishes.
It was not until the 1920s that significant advances were made in the design of these machines when permanent pipes were introduced to connect them to a constant supply of water. Only restaurants, hotels and wealthy families had these appliances as they were large and expensive and it was not until 1937 that a dishwasher small enough for a home was built. It was built by William Howard Livens and was more like the washing machines we have today with mesh baskets inside a metal container and a front opening door with a drying element introduced in his design in 1940. Gradually they became more smaller, cheaper and more efficient and by the end of the 1950s they became popular as a kitchen appliance. The popularity continued to rise and most houses in the US owned one by the late 1970s. Today they are popular throughout Europe and the Middle East, where they took longer to catch on than in the US. .
A wide range is available today with many renowned manufacturers such as Whirlpool, Bosch Maytag, GE and many others creating a very competitive market.
