Who invented the dishwasher?

Do you know when the first dishwasher was born? Who invented, and its “glorious” history? Let’s find out right now!

Like many other daily household chores, washing dishes is really a boring “task”. We often hear the words “lament the responsibility” of those who are about to “wrestle” with the greasy pile of dishes, and almost never see anyone shouting “I love to wash dishes!”

People tend to invent tools and machines to replace the jobs that they do not want or are able to do. That is the reason for the advent of washing machines, coffee makers, robot vacuums as well as countless other great and small inventions … And the dishwasher is no exception. So you know when the first dishwasher was born? Who invented, and its “glorious” history? Let’s find out right now!

The first dishwasher

The earliest known dishwasher was developed 160 years ago. It revolutionized the way, bringing sleeker modern dishwashers with a host of useful features that we know today.

Initially, the patent for a rudimentary dishwasher dates back to 1850, invented by Joel Houghton. His design prototype is made of wood, and when activated, water passes through the wooden plumbing and sprayed onto dishes. In general, this dishwasher model runs on mechanical power but does not use electricity, so it is evaluated as cumbersome and slow. It is not very applicable, it consumes even more labor than washing by hand.

It was not until 1887, when inventor Josephine Cochrane made a series of advanced enhancements to Joel Houghton’s rudimentary system and presented it at the Chicago World Fair in 1893. Since then, the public has learned of a automatic dishwasher. In addition, it was Josephine Cochrane who created and sold the first commercial automatic dishwasher, for which she was recognized as the inventor of self-contained, self-contained dishwashers – what we know today.

How does Josephine Cochrane’s dishwasher work?

When Cochrane built the first automatic dishwasher, it was a rather cumbersome system. But it can be operated automatically with the dish stacks connected to a flat wheel system inside a copper boiler. The engine spins the wheels while hot soapy water is sprayed up from the bottom of the boiler and poured over to where the dishes are housed in circular, framed wire compartments.

The Cochrane dishwasher was the first to use pressure water instead of detergent to clean the dishes inside. The motor can be powered or controlled manually via a pulley.

Today’s modern dishwashers

The success of the first automatic dishwasher of Cochrane has made people increasingly interested in this useful device. At the same time, large companies began to invest in developing their own dishwashers. By the 50s of the last century, dishwashers had become popular household items in well-off households in America, as well as widely used in hotels and restaurants.

Although dishwashers are becoming more and more complex in technology, the principle of automatic washing has not changed much. The key to achieving high efficiency is the perfect interaction between water pressure, temperature, time and cleaning solution.

Over time, dishwashers are constantly improving to become more efficient, support more features, and especially save water and energy. Most Americans (75%) currently own a dishwasher in their home. What’s more, modern dishwashers are easier to use. They come with more complicated pre-soak cycles, detachable trays, better racks and sprayers … In general, today’s dishwashers are manufactured towards the following criteria: Safety, economical, dry, clean and quiet.

Dishwashers have helped free up a great deal of women’s work. Helping women save significantly time burying their heads in housework, reducing labor force and becoming more equal in society. In addition, they also become one of the symbols of a comfortable and modern life.

Above all, Josephin Cochrane is considered one of the great contributors to the women’s liberation movement.
