How about an insulated electric kettle? Necessary heat preservation and boiling water artifact for urban life

With the improvement of living standards, consumers have higher and higher requirements for electric kettles. Thermal insulation electric kettle appeared on the market. The appearance of thermal insulation electric kettle combines boiling water with thermal insulation, which facilitates life and improves efficiency. The insulated electric kettle adopts steam intelligent induction temperature control, which has the functions of automatic power off after water is boiled and preventing dry burning and power off. With the needs of life, the current electric kettle is also developing in the direction of multi-function, such as anti-leakage, anti-scald, water locking and so on. The thermal insulation electric kettle has the advantages of fast heating speed, good thermal insulation effect, strong filtering function and various styles.

Working principle of thermal insulation electric kettle

The working principle of the electric kettle is that the steam generated when the water boils deforms the bimetal of the steam temperature sensing element, and the power switch is pushed by the deformed lever principle, so that the electric kettle is automatically powered off after the water boils. Its power failure can't be automatically reset, so the kettle won't be automatically reheated after power failure.

Using PTC heating element instead of heating tube can effectively prevent the fire danger caused by dry burning. The dry burning temperature of PTC heating element can be set at any temperature between 150℃ and 250℃. When the temperature reaches the set temperature, the resistance of PTC element increases rapidly, and the heating power drops sharply, keeping its temperature at the set temperature and not rising any more. The automatic temperature control performance of PTC heating element is absolutely reliable. It controls the temperature through the change of resistance in PTC body, not through any contact. So many high-grade electric kettles use PTC heating elements. However, many electric kettle designers are not used to using PTC heating elements, and PTC is expensive and bulky, so its application is limited.

PTC heating element has great advantages in heat preservation of electric kettle. The insulation power of the electric kettle is relatively small, and the use of PTC heating elements will not increase the cost. PTC heating element has the function of preventing dry burning, and the dry burning power is about one tenth of that of boiling water. When the temperature control element fails, the temperature of PTC itself remains low, so there is no danger.

How about an insulated electric kettle?

. 1. Compared with other electrical appliances, especially drinking fountains, kettle boiling water is much cleaner. No matter how clean the water dispenser is, there are still dead ends. Some people don't wash it for months, but it's best to buy a stainless steel electric kettle. Now good stainless steel electric kettle is basically 304 stainless steel, tasteless. The plastic electric kettle is a little plastic.

You may be worried that the electric kettle may not turn on automatically. You hardly need to worry about this problem. If the requirements are higher, you can buy an electric kettle with an imported thermostat. The coupler (the center of the bottom of the electric kettle) is printed with the words strix or otter in English, indicating that it is an imported thermostat. The imported thermostat is powered off accurately. After 10 thousand tests, it is guaranteed to be boiled water.

In fact, compared with the accuracy of power failure, what is more worrying is that water heating appliances other than electric kettles, such as water dispensers, can only burn to about 90 degrees. Once the water source is impure, hepatitis B and hepatitis A cannot be inactivated below 100 degree; Open-flame kettle can only judge whether it is boiled manually, and it is definitely not allowed. Either it's not cooked or it's overcooked (so the water doesn't taste good)

4. Scale problem, the electric kettle will definitely produce scale, but so will the open flame kettle. The drinking fountain is dirtier. So the electric kettle will be clean as long as it is washed frequently.

I believe that through the above understanding, everyone should have a general judgment on how to keep the electric kettle warm. Electric kettle is a common small household appliance in our daily life. It integrates boiling water and heat preservation, which really facilitates our life. In this society where the pace of life is accelerating, we need such multifunctional small household appliances to improve our quality of life.
