As technology is becoming more and more developed, electric kettle is an indispensable part of life today, and its convenience and quickly provides great convenience for each family.As an electrical product, you must spend more attention to buying. It is better to compare which kind of kettle? If you do n’t know how to choose a electric kettle, look at it with Xiaobian!
Electric kettle principle
working principle:
After the power of the electric kettle was connected to the power for about 5 minutes, the water temperature gradually rose to 100 degrees, and the water began to boil. The water vapor deforms the dual metal sheet of the steam temperature sensing element.If the steam switch is effective, the water in the pot will keep burning until the water is burned, and the temperature of the heating element will rise sharply. There are two dual metal slices located at the bottom of the heating plate.Open power.Therefore, the safety protection device of electric kettle is very scientific and reliable.This is the principle of triple safety protection of electric kettle.
Principles of thermal insulation:
Most of kettles with thermal insulation function have two heating pipes, and one insulation and heat tube is controlled by the insulation switch separately. It allows users to control whether to choose insulation.The insulation power is generally below 50W, and one hour usually does not exceed 0.1 meters.
Which electric kettle is good
Electric kettle purchase
① Volume.Electric kettle is generally 1.7 ~ 2.0L. This depends on demand. According to its own conditions and actual needs, 2-3 people can choose 1.2L ~ 1.5L electric kettle; 4-5 people can choose 1.8L ~ 2.0L of 1.8L ~ 2.0Lelectric kettle.
② Appearance.Take a closer look at it from the inside to the outside.By the way, shake and shake.Look at the kettle workmanship, is the seam tight? Is the plastic parts have burrs and whether the material is evenly? Whether the metal pot body is smooth and shiny.Big factories are usually strictly tested and generally avoid these problems. Is the workmanship excellent? If there is no sound after shaking, the pot is loose, which is an unqualified quality problem.
③ Electrical performance.Reading instructions when buying, whether there is CCC forced certification.You can test the burning when you buy it, whether the heating power of the nominal nominal is met, and whether the water burning time meets the expectations.Whether the insulation performance is good and not hot.Check whether the temperature control device is normal. The current electric kettle has a temperature control device, and the power is disconnected after burning.This will prevent dry burning.
④ Quality.The principle of electric pot switch is that when the water is boiling, the steam is heated and deforms by the metal sheet metal of the temperature sensing element through the catheter, which is disconnected.The power -off process is irreversible, so there will be no second heating.After the water is boiling, the temperature control element will automatically power off without burning.This is still very safe.
⑤ crowd.If there are elderly people and children in the family, the insulation electric kettle is recommended.Such kettles have special anti -scalding, anti -leisure overflow design, and protect the elderly and children.
How to remove scale in electric kettle
1. Vinegar eliminate scalm
This method is the simplest and most practical method. Everyone knows that the main component of the scale is carbonate such as calcium carbonate. The acetic acid in vinegar will react with it to produce substances and carbon dioxide gas dissolved in water. Generally, supermarkets are all supermarkets.Can buy white vinegar, put 10%of the white vinegar of the kettle scale, then add water, boil and open for about one hour, and then wash it. The vinegar is also fine, but the effect of vinegar is not as good as white vinegar.
2. Boil potato with electric kettle to remove dirt
In the new, put the potato above half a kettle, fill the water, cook the potato, and burn the water in the future.But pay attention to the kettle to cook the potato, do not scrub in the inner wall, otherwise it will lose the effect of dirt.For the old kettle that has been filled with scale, after cooking the above methods for one or two times, not only the original scale will gradually fall off, but also can prevent re -stagnant scale.
Third, the soda to remove the scale
Generally, the electric kettle heating plate is made of aluminum. When the electric kettle is boiled, it is easy to form scale. Generally, we can put 1 spoon of baking soda. Boil a few minutes and remove the scale.Or it can also pour about 500 grams of soda with a concentration of 1%, gently shake, and the scale can be removed.
Fourth, cook eggs and remove scale
Generally, the electric kettle is hard to remove after a long period of dirt. If you use it to cook the egg twice, you will receive the ideal effect. Slightly shatter the two eggshells, put it in the bottle, and then put it in half a pot of water.Stir with a mixer or puff, then boil, place it for about half an hour, pour out the eggshell, and then wash it with water twice.
