Reform of domestic boiled water in China;

1, stove

I believe many rural friends have seen such stoves when they were young. When I was young, my grandmother used this stove to boil hot water and then stored it in a thermos.

2. Kettle

When I am older, I have a kettle at home, which is heated by a gas stove or charcoal fire. It seems a little advanced, and it doesn't need firewood. However, the storage method of hot water has not changed, and it is still a thermos bottle.

3. Electric kettle

2 1 century, electric kettle has become the best-selling item in the world. The electric kettle adopts steam intelligent induction to control the temperature, which has the functions of automatic power-off after the water is boiled, preventing dry burning power-off, etc., which greatly facilitates people's lives and has become a common choice for drinking hot water at home.

4. Health pot

Because it can not only boil hot water, but also boil scented tea, hot milk and health porridge, it is very popular among modern young people. Moreover, the health pot has heat preservation function, which is convenient to clean and cheap.

5. Clean the heat engine

All-in-one cleaning and heating machine is a relatively novel way of boiling water, which integrates filtration, purification and heating. Tap water is filtered by a composite filter into direct drinking water, and then heated by instant heating technology, which can automatically adjust the temperature and water quantity and burn as much as you want. But the price is also more expensive than the previous models. After all, boiled water is direct drinking water.
