In 1954, the United States GE produced the first electric desktop dishwasher, which not only improved the washing performance, but also improved the volume and shape of the whole machine.

The earliest research on dishwashers in Asia was Japan. By the mid-to-late 1990s, Japan had developed microcomputer fully automatic desktop dishwashers.

At the same time, Europe and the United States have developed household dishwashers into kitchen appliances with a unified image.

At the same time, you can also choose a dishwasher with fast washing, flushing, scooping and rotary spraying functions.

Some data show that in foreign countries, the penetration rate of household dishwashers has reached 30% -40%, the United States, France, Germany and other countries are as high as 60% -70%, and Southeast Asian countries are developing at an annual rate of 20%. In China, although some companies started to produce desktop dishwashers in the mid-1980s, there have been more than a dozen imported and domestic brands on the market, but the sales momentum has not changed significantly.

Since the late 90's, the topic of dishwashers has gradually increased. A data provided by China Light Industry Information Center shows that dishwashers have become one of the fastest-growing energy products in China. A survey of 2,200 households in ten major cities of Beijing, Shanghai, Guangzhou, Shenzhen, Nanjing, Hangzhou, Wuhan, Shenyang, Chengdu, and Xi'an by a shopping mall showed that respondents' immediate purchase rate for dishwashers was 2. 3%, and another 6.4% of families have a desire to buy. Based on this calculation, the national demand for dishwashers is nearly 7 million.

It is not difficult to find through the live demonstration of the shopping guides in the shopping mall. Compared with the traditional manual dishwashing, the dishwasher does have many advantages: because it eliminates the steps of manual dishwashing and other steps, it adds drying, Disinfection and other links, so reduce the chance of infection of bacteria; and because of the use of water circulation and convection, water saving effect is obvious; some models have the function of softening water, which can reduce the scale formation in the machine and make the tableware brighter Clean.

What needs to be improved is also obvious. The first is the long washing time. Since the setting procedure is a whole process, even if there are only a few pieces of tableware, the complete process must be taken. Normal tableware with less stains usually takes about 15 minutes. Including drying, disinfection and other processes, it takes more than an hour.

In addition, the purchase of special detergents and the installation of special water pipes have brought some inconvenience to users. In addition to inconvenience, dishwashers are also affected by price and are not widespread.
