Is the automatic electric kettle safe? How to clean the electric kettle?

I believe many people have heard of the electric kettle with automatic water addition, but this kind of electric kettle is more convenient than ordinary electric kettle. So, is it safe to use the electric kettle with automatic water addition? How to clean the electric kettle? These are all issues that everyone cares about. Let's introduce them in detail according to this issue.

So, is it safe to use the electric kettle with automatic water addition? How to clean the electric kettle? These are all issues that everyone cares about. Let's introduce them in detail according to this issue.

Is the automatic electric kettle safe?

1, automatic temperature control is a heat preservation function. Press the heat preservation key, set the temperature, and the electric kettle will automatically keep warm. 2. The working principle of the electric kettle is that the bimetal of the steam temperature sensing element is deformed by the steam generated when the water boils, and the power switch is pushed by the deformation transfer 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. 3. Replacing the heating tube with PTC heating element can effectively prevent the fire hazard 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, so that the temperature is kept at the set temperature and will not continue to rise.

4. The automatic temperature control performance of 4.PTC heater 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.

5. Many electric kettle designers are not used to using PTC heating elements, and PTC is relatively expensive and bulky, so its application is limited.

How to clean the electric kettle

1, vinegar scale removal

This method is simple and practical. As we all know, the main component of scale is carbonate such as calcium carbonate, and acetic acid in vinegar will react with it to generate water-soluble substances, minerals and carbon dioxide gas. Generally, you can buy white vinegar in supermarkets, put it in 10% of the kettle scale, then fill it with water, put it around after boiling, and then scrub it. Old vinegar is ok, but the effect of old vinegar is not as good as white vinegar.

2. Boil the sweet potato in a kettle to remove scales

In a new kettle, put more than half a pot of sweet potato, fill it with water, cook the sweet potato, and then boil the water, so that scale will not accumulate. However, it should be noted that do not scrub the inner wall of the kettle after cooking the sweet potato, otherwise it will lose the descaling effect. For the old kettle that has been covered with scale, after being boiled once or twice by the above method, not only the original scale will gradually fall off, but also it can prevent the scale from accumulating again.

3, baking soda in addition to scale

Generally, the heating plates of electric kettles are all made of aluminum. When boiling water with an electric kettle, it is easy to form scale. Generally, we can put 1 teaspoon baking soda and boil it for a few minutes, and the scale will be removed. Or you can pour in about 500g of baking soda water with the concentration of 1% and gently shake it to remove the scale.

4. Boil eggs to remove scale

Generally speaking, the electric kettle is difficult to take off after a long time. If you cook eggs with it twice, you will get the ideal effect. Break two eggshells slightly, put them into a bottle, then put them into a half pot of water, stir them with a stirrer or spoon, then boil them, leave them for about half an hour, pour them out and rinse them twice with clear water.

The above content is a detailed introduction to the safety of automatic water-adding electric kettle and how to clean it. As you can see, through the above, you can choose the right electric kettle.
