Inventor of the dishwasher
Like many household chores, washing dishes is always a boring "task". There will always be "complaints" from people who are about to "struggle" with piles of dishes every day. They are greasy, dirty, covered in food scraps, and never see someone say "washing dishes is my favorite job".
Starting from "laziness"
We humans have always tended to learn and invent tools and devices to make life easier throughout human history. That is the reason for the birth of dishwashers, oil-free fryers, coffee makers, as well as countless other large and small inventions. And the dishwasher is no exception. So who was the inventor, when and how have dishwashers changed since then? Let's find out right below!
The first lazy person
|
About 160 years ago. The first dishwasher created a revolution, bringing modern dishwashers with sleeker designs and a series of useful features that we know today. Initially, the first primitive machine was patented in 1850, created by Joel Houghton. His design was originally made of wood, and once started, water passed through the wooden plumbing, and sprayed onto the dishes. Dishwasher models at that time ran mechanically, but could not use electricity like they do now. So it's quite cumbersome and slow. It even consumes more energy than washing dishes by hand. |
Thoughts continue
It wasn't until 1887 that the next "lazy" person, inventor Josephine Cochrane, improved it and presented it at the 1893 World's Fair. The concept of a self-contained, automatic dishwasher and the sale of one The world's first automatic dishwasher. Commercially, she is recognized as the inventor of the automatic dishwasher with a closed process - something we know and use today.
How Josephine Cochrane operates the machine
The machine can operate automatically with the dish stacks connected to the wheel system in the copper boiler. The motor will rotate the wheel while hot water and soap will be sprayed from the bottom of the boiler.
Cochrane's dishwasher was the first to use water pressure instead of detergents to clean dishes inside the machine. The motor can be powered or controlled manually via a pulley.
Inheritance and development
"Good reputation spreads far and wide", by approaching the right needs, as well as laying the foundation for dishwashers. The success of Cochrane has made people increasingly interested in this useful device. After that, large companies also began to invest and develop their own dishwashers. Until the 50s of the last century, dishwashers became a popular household appliance in middle-class and upper-class families in America. Widely popular in restaurants and hotels.
Now and future
Dishwashers have contributed to releasing a large amount of work. Helps people save a lot of time, reduce labor and costs. In addition, the dishwasher has also become one of the symbols of a comfortable, modern life.
In the past, above all, Josephine Cochrane was considered one of the great contributors to the movement to fight for the liberation of women with busy housework. But in the present, she is the one who has played a big part in preserving the happiness of many families, as well as freeing up work for each husband when the East is gradually lacking warmth.
