The first dishwasher was invented in America
in 1850, Joel Houghton patented a wooden machine with a
hand-turned wheel that splashed water on dishes, it was hardly a
workable machine, but it was the first patent.
in 1865 L.A. Alexander obtained a patent for a device that
used a hand crank and gearing to spin a rack of dishes through the
dishwater again this didn't do to much to clean dirty dishes.
In 1886, Josephine
Cochrane proclaims in disgust "If nobody else is going to invent a
dishwashing machine, I'll do it myself." And she did, Cochrane
invented the first practical dishwasher. Cochrane had expected the
public to welcome the new invention, which she unveiled at the
1893, World' Fair, but only the hotels and large restaurants were
buying her ideas.
Cochrane's machine was a hand-operated
mechanical dishwasher. As this was before electricity was
widespread She founded a company to manufacture these dish
washers, which eventually became KitchenAid. other company's
produced dishwashers that were powered by steam and designed for
restaurants and caterers. They usually worked by passing the dirty
dishes under jets of hot water by means of a conveyor belt or a
revolving basket. They were generally inefficient. It was not
until the 1950s, that dishwashers caught on with the general
public as they became cheaper and a more usable size.
Josephine Cochrane was quite wealthy and
granddaughter of John Fitch the inventor of the steam boat. She
never washed dishes herself and only invented the dishwasher as
servants were chipping her nice china.
