Dishwasher is very convenient, who accidentally discovered it? How was it discovered? Cochrane's dishwashing troubles began after she married wealthy businessman William Cochrane in 1858. As a socialite, she often held parties. She would entertain guests on her expensive heirloom china. Servants often broke delicate cutlery while washing dishes. So she started washing the dishes herself. However, she broke a lot of dishes herself, so she decided to design and build a machine that would wash them faster and more carefully than by hand.
Dishwasher is very convenient. In order to improve the efficiency of machine washing dishes, Cochrane measured the length, width and height of plates, cups and saucers, designed a mesh basket that can accommodate tableware, and placed It is divided into several compartments. At the bottom of the machine is a container for soap. According to Lemelson-MIT's plan, the basket was placed inside a wheel that lay flat in a copper boiler. Soapy water is sprayed onto the plates, while the motor turns the wheels to begin cleaning the dishes.
In 1886, Cochrane obtained a U.S. patent for a dishwasher and named it the Cochrane dishwasher. She advertised her invention in local newspapers and built a dishwasher for friends and family. To increase sales, Cochran exhibited his machine at the 1893 Chicago World's Fair, where his dishwasher won awards for its design and durability. Orders poured in from her appearance, and she opened a manufacturing plant near Chicago. Her dishwashers were extremely popular in the hotel industry, but did not become popular in the public eye until the 1950s.
"Some housewives said they preferred to wash dishes by hand. It was said that dishwashers at the time caused soap stains on the dishes." While many homes built before the 1950s use furnaces to heat water, not all furnaces can heat enough hot water to run a dishwasher. It was not until 1995 that the dishwasher market restarted in China and entered the era of fully automated dishwashers. People's ideas have changed, and dishwashers have also been improved for Chinese tableware, cleverly using price competition to seize the market, and using media publicity to increase visibility.
