under one roof_600字

　　In fact, there are not so many of the same things in Chinese, so sometimes it's easy to make mistakes in Chinese expression. In Chinese, there is a saying that it is under the same roof.

　　A few days ago, I said I wanted to have a try. I bought a hot water dispenser for me. I usually pay more attention to new products. If I want to use the theory of innovation diffusion, I am probably the early adopter. At the very beginning, I had some doubts about the practicability of this product, because I was used to using the traditional water dispenser to pick up water or using an electric kettle to boil water at home.

　　However, after using it, we found that the user experience is very good. We often want to drink a cup of warm water and directly connect it with boiling water. Well, you can't drink it. When you remember that there is a cup of hot water on the table, that cup of water has already become cold water. That is hot drinking machine is very good, to avoid this problem.

　　His water temperature preset a number of gears, including cold water at room temperature, 45 ℃ warm water, 75 ℃ hot water and 99 ℃ boiling water. These temperatures cover all kinds of use scenarios in life, and you can drink water at the desired temperature at any time. From the perspective of environmental protection, the hot water dispenser also avoids the repeated heating of water by the traditional electric kettle, and reduces the unnecessary loss of energy. Only pure water needs to be put into the device to meet the drinking water demand in daily life.

　　You don't need to mix cold water and hot water as before to get the water temperature you want. In a sense, it's really not a necessity. But it is undeniable that new products make life more convenient.
