Dishwasher who invented

Wire compartments held dishes which were sprayed with hot soapy water The wheel was turned by using a hand crank on the outside the machine Though it worked, only hotels and large restaurants bought her dishwashers and it was not until the s that the dishwasher was sold to the general public Cochran went on to produce dishwashers with her own company, a company that later became KitchenAid After moving to Illinois, Cochran set out to design a washing device after commonly finding plateware chipped from hand washing.

She designed a set of wire compartments, each created to fit plates, cups, or saucers. The compartments were placed inside a wheel that lay flat inside a copper boiler, while a motor turned the wheel, pumping hot soapy water from the bottom of the boiler. The machine was showcased in the World Columbian Exposition of , helping to establish a market for the dishwasher in hotels and large restaurants.

Since most homes' hot water heaters could not supply the amount of hot water the dishwasher required, the machine's large size limited the company's sales. Josephine Cochrane, inventor of the first commercially successful dishwashing machine, was born in Ashtabula County, Ohio in Her father was a civil engineer, and her great grandfather, John Fitch, was an inventor known for his steamboat-related innovations.

Cochrane, thus, may have had creative tendencies in her family. However, she was not formally educated in the sciences. Cochrane was a socialite. She and her husband William often entertained guests at their home.

Accustomed to having servants do much of her housework for her, Cochrane set out to create the dishwasher after realizing her fine china would often chip when being scrubbed in the sink.

At first, Cochrane tried washing the dishes herself. But she found the task burdensome and thought to herself that there must be a better way. She worked out a design, one that employed water jets and a dishrack that would hold the soiled tableware in place.
