LWashing dishes is really not a good job. Cooking can be praised by family and friends, and many people even enjoy it. But when it comes to washing the dishes, except for your mother who praised you when washing the dishes, no one really praised you for cleaning the dishes, right? The popularity of dishwashers has effectively reduced the labor intensity of those with low status at home.

The principle of the dishwasher is quite simple to say, it is “rinsing”, the spray arm sprays high-pressure water to rinse the tableware to achieve the purpose of washing the tableware. But every dishwasher is not so simple in actual washing. Tableware has different materials, such as glass, porcelain, iron, stainless steel, etc.; tableware also has different shapes, such as bowls, saucers, cups, and pots; The food residues and oil stains left on the tableware in different regions are not nearly the same. How to clean these is a very big knowledge. Solving these problems is not achieved overnight. It is a step-by-step improvement in the history of the development of dishwashers. Modern dishwashers mostly include multiple washing steps such as cleaning, disinfection and drying. With the advancement of the times and technological innovations, dishwashers are becoming more and more perfect in solving the trivial matter of dishwashing.

The main thing that hinders dishwashing in the first place is water. In early civilizations, people could only cook limited food and use limited tableware. After eating, people took the tableware to streams and ponds to wash. The second option is to bring the water back to wash the dishes. In the early 20th century, water could finally be introduced into the room through tap water pipes, not only for bathing, but also for kitchen water. This is also a necessary condition for the subsequent development of dishwashers.

dishwashers-historyThe first patent for a dishwasher appeared in 1850, owned by Joel Houghton, and many others followed over the decades. But limited by the technical conditions at that time, most of these dishwashers were relatively large devices, and the power was developed from manual to steam power at the beginning, and the removal of oil stains could only be done by hot water. Some load the tableware in a cradle-like device, and then place the “cradle” in hot water to vibrate; some use a toggle to let the water flow back and forth between the tableware; some fix the tableware on a round shelf , and then create a swirling stream of water through the paddle to hit the tableware.

In 1875, C. E. Hope Vere finally developed the water jet method, which was the prototype of the modern dishwasher washing principle, spraying water on the dishes, a concept later adopted by other inventors. Later Blick dishwashers used a water-spraying propeller to squirt a stream of water onto a rack full of dishes, a technique still used today.

In addition, there is also an ultrasonic type. Although it sounds quite high, it is far less practical than the spray type. The reason is to move to the working principle of the dishwasher and the washing process.

In 1915, the first publicly displayed automatic dishwasher appeared. In 1929, the German company Miele produced the first electric household dishwasher in Europe. However, it was still a relatively simple “machine” and was not suitable for the kitchen. use.

It was not until 1930 that the dishwasher really entered the threshold of ordinary families, but the dishwasher did not become popular on a large scale. The refrigerator invented at the same time quickly swept the United States. In fact, it is not difficult to understand. After all, it is necessary to preserve food Much more important than washing dishes. One of the reasons why it was not popular was that the efficiency of dishwashers at that time was too low to completely replace manual dishwashing. At the same time, due to the development of detergents at that time, there was no special detergent for dishwashers, so the washing effect was not good. very ideal.


In the 1950s, special detergent for dishwashers was invented, and GE also produced the first electric desktop dishwasher, which not only improved the washing performance, but also improved the volume and shape of the whole machine, and the public began to slow down. Slow to show more interest.

In the 1970s, with the increase of working women, Miele produced the world’s first microcomputer-controlled dishwasher, which made the relationship between man and machine closer, and the household use of dishwashers was better reflected. Dishwashers have only begun to become popular. Although it is not possible to say that every family has a dishwasher, more and more families are beginning to use dishwashers.

Japan was the first to research dishwashers in Asia. By the middle and late 1990s, Japan had developed a microcomputer automatic desktop dishwasher. The companies represented include Panasonic (National), Sanyo (SANY), Mitsubishi (MITSUB ISHI), Toshiba (TOSHIBA) and so on.

At the same time, Europe and the United States have developed household dishwashers into kitchen appliances with a unified image. Companies represented by Europe and the United States include companies such as Miller (Miele), Siemens (SIEMENS), and Whirlpool (Whirlpool).
