The electric kettle is an indispensable part of today’s life that provides us with great convenience. Do you know what is an electric kettle? I believe most of you know.

As an electrical product, you have to pay more attention when you want to buy it. I think you will often worry about which electric kettle is good?

To judge which one is good, you have to first understand the working principle, advantages and disadvantages, and precautions.

The following is an introduction to the electric kettle and the descaling method.

What Is An Electric Kettle?

The electric kettle was born in Chicago in 1891. With the development of science and technology, fast, safe, and convenience become the main feature of the kettle.

The British tea lover has fallen in love with it since then. In the 21st century, it has become a global bestseller. It adopts the steam intelligent temperature control, which has the function of automatically powering off after the water boils, overheat protection, and anti-dry protection.

With the needs of life, the current electric kettle is also developing in a multi-functional direction, such as leak prevention, anti-scalding, and water lock. It has the advantages of fast heating speed, good heat preservation, and many styles.

How Does It work?

After the electric kettle is turned on for about 5 minutes, the water temperature gradually rises to 100 degrees, the water begins to boil. The water vapor deforms the bimetal of the steam sensing element and disconnected from the power supply automatically. If this mechanism fails, the water will continue to burn until the water is dried.

The temperature of the heating element rises sharply. There are two bimetals at the bottom of the heating plate, which will rise sharply due to heat conduction, and will expand and deform. And finally, shut off automatically.

Therefore, safety protections are designed to be very scientific and reliable. This is the double safety principle of the electric kettle.

How To Remove Scale



This method is the simplest and most practical method. Everyone knows that the main component of scale is carbonate such as calcium carbonate. The acetic acid in the vinegar reacts with it to produce minerals and carbon dioxide gas dissolved in water.

1. To extend the life of the kettle, the mineral deposits in the pot should be cleaned regularly.

2. When cleaning, be sure to disconnect the power supply first.

3. Please do not soak the kettle base in the water.

4. Mix the vinegar and water in a ratio of 1:2 and pour into the kettle, then turn on the power, let the kettle work and wait for it to automatically shut off.

5. Allow the mixture to store in the kettle for 24 hours, then pour off the mixture. Then refill with the freshwater and boil it again.

6. Pour off the water and remove the scale and vinegar. Finally, clean the inside with water. Repeat as necessary.

7. In the process of using, if the fault occurs, the kettle should be taken out from the base, pour all the water, and then cool down to normal temperature for fault detection or cleaning.

Note: Water should not exceed the “MAX” line to prevent the water from overflowing. Also can’t go to heat milk tea and other drinks! Unless the specification clearly indicates that it can be heated.

During the boiling process, the lid cannot be opened and cannot be touched to prevent burns. After boiling water, unplug it.

Baking Soda

removed. Or you can pour about 500 grams of baking soda. Gently shake it and the scale can be removed.
