The first recorded evidence of a dishwasher was from 1850 when a easy hand turned splashing gismo attached to a wooden tub made by Joel Houghton was given a patent. Developing on this idea L.A. Alexander added gears to a spinning rack holding dishes that allowed it to be spun inside a tub of water and this was patented in 1865. Both of these were very crude and made entirely of wood and did not de facto clean dishes very well.
Josephine Cochrane was a wealthy woman and had engineering in her blood as her grandfather John Fitch was renowned for inventing the steamboat. She also liked to entertain friends oftentimes and hold collective events at her home resulting in a lot of dishes needing to be cleaned each time. The crockery she used for sharp was costly and was often getting broken by the servants while washing up. Getting fed up with this she decided to build a dishwasher that could wash dishes fast without breaking them. She built a engine consisting of a wooden wheel lying flat in a copper boiler which could be turned either by hand or driven by a power source via a pulley. Wire framed compartments made to fit her dishes were attached to this wheel and the combination of it spinning and soapy hot water being showered on them by the boiler resulted in the first effective dishwasher.
She took her dishwasher to the world fair in 1893 in Chicago where it won the top award and citizen ranging from friends to hotel and cafeteria owners were queuing up request for a dishwasher engine of their own. fast she patented the invention and opened a output facility to build them and this firm became the household appliance giant today known as KitchenAid. More fellowships also started making other versions some with conveyor belts and others with baskets spun by various methods both using a jet or spray of hot water poured from above to clean the dishes.
It wasn't till the 1920's that any primary advances were made to the make of these machines when permanent plumbing was introduced to hook them up to a constant water supply. Only restaurants, hotels and wealthy families had these appliances as they were large and costly and it wasn't till 1937 that a dishwasher small adequate for a home was built. It was built by William Howard Livens and looked more like the washers we have today with mesh baskets inside a metal container and a front occasion door with a drying element introduced into its make in 1940. Gradually they became smaller, cheaper and more effective and by the end of the 50s were getting more popular as a home kitchen appliance. Popularity continued to increase with most homes in the Usa owning one by the end of the 70s. Today they are popular all through Europe and the Middle East where they took longer to catch on than in the Usa.
A large range is ready today with many big name manufacturers like Whirlpool, Bosch Maytag, Ge and many other creating a very contentious market.
