Because people's life now requires quality and convenience, people habitually choose tools with more functions. Not only a hot kettle, but also a rice cooker. A long time ago, people's rice cookers had a single function and could only cook. However, with the development of science and technology, rice cookers with more functions have been produced. People in this country call it rice cooker or pressure cooker, which can not only cook rice, but also cook soup, porridge and stew vegetables, thus realizing multifunctional kitchen appliances and bringing a lot of convenience to people's lives.
People first began to boil water in pots, and gradually developed various tools for boiling water, bringing forth the old and bringing forth the new. Each generation is more advanced and has more comprehensive functions. Moreover, the new water boiling tool can not only boil hot water, but also cook porridge, soup and so on. It is a multi-purpose product, which not only increases convenience but also increases practicality. Therefore, this simple water boiling tool must have been eliminated by people.
Now people not only pay attention to the quality of life, but also pay attention to food safety and personal safety. Although it is convenient and fast to heat, heating with a heating pipe will pose a certain threat to personal safety. At the same time, boiled water is not particularly safe, so it is gradually eliminated by people. ?
