What is the Definition of a dishwasher?

A dishwasher is a household appliance designed to automate the process of cleaning and sanitizing dishes, utensils, and cookware.


Historical background of dishwashers

Dishwashers have come a long way since their invention in the late 19th century. From manual labor to innovative technology, dishwashers have revolutionized kitchen cleaning routines.

The first mechanical dishwashing device was patented in 1850 in the United States by Joel Houghton. This early device, constructed from wood, required manual cranking while water was sprayed onto the dishes. However, it proved to be slow and unreliable, leading to limited adoption. In 1865, L.A. Alexander received a similar patent featuring a hand-cranked rack system. Despite these early innovations, both devices faced practical limitations and failed to gain widespread acceptance.

Some historians attribute the slow adoption to the prevailing societal perception that emphasized the value of women’s effort in housework rather than seeking ways to simplify it. This perception hindered the recognition of the importance of time-saving household appliances.

When and where was the first dishwasher invented?

The first dishwasher was invented in the late 19th century. It was invented by Josephine Garis Cochrane together with mechanic George Butters in 1886 in the United States.
