When it comes to electric kettles, I believe everyone is no longer unfamiliar with them. Every household must have an electrical appliance that is inseparable from every day's life. Therefore, there are many people who worry about whether long-term drinking water from an electric kettle will have any adverse effects. I will introduce it in detail below and answer your questions.
The working principle of the electric kettle
After the electric kettle is turned on and heated, the water temperature gradually rises to 100℃, the water starts to boil, and the water vapor impacts the bimetal on the steam switch. Due to the effect of thermal expansion and contraction, bimetal The slice expands and deforms, and uses the deformation to push the power switch through the lever principle , so that the electric kettle will automatically power off after the water is boiled.
The convenience brought to us by the electric kettle
When the electric kettle does not appear, rural families generally use wood fire to boil the water. It takes tens of minutes to boil the water once, and you have to guard it yourself Keep adding firewood, if you don’t reserve boiled water one day, you will be in a hurry if you happen to come.
The emergence of the electric kettle has just solved this series of problems. Its biggest advantage is that it is efficient and fast, no oily smoke, automatic power-off, and it can be burned at any time at any time, saving time and effort. For families who like to drink tea or have children at home, it is very convenient to have an electric kettle.
Is long-term drinking water from an electric kettle harmful to our health?
The question that everyone is most concerned about may be whether drinking water from an electric kettle for a long time will harm our body?
It can be clearly stated that if the electric kettle you buy is made of 304 stainless steel produced by a regular manufacturer, it will not harm the human body.
However, it is inevitable that some merchants will save costs and replace them with other inferior materials, such as 201 and 202 stainless steel. These two materials are high manganese steels, which contain close to 10% of manganese. This kind of kettle is used to boil water for a long time. , The manganese inside is likely to be dissolved out, If the human body consumes too much for a long time, it will damage the human nervous system, make the human memory decline, and cause depression.
How to choose a qualified electric kettle
How to buy a qualified electric kettle?
- Look at the logo on the inner wall of the electric kettle. When we buy, we can check whether the inner wall of the electric kettle has "304 mark" and "GB9684 mark". If there is, this means it is a qualified product and can be purchased with confidence; if 201, 202 or nothing is marked , It is not recommended to buy, this is probably a substandard product.
- Choose a brand. There are many electric kettles on the market, and it is difficult for us to distinguish which ones are good. To be on the safe side, we can choose branded products, such as Supor or the trusted popular brands of Midea.
- See price. Many people may be eager for cheap, so they just buy a 20 or 30 yuan kettle online. Although it can be used, we cannot guarantee its safety. As the saying goes, you get what you pay for. It is recommended to choose a slightly more expensive item, about 100 yuan.
Matters needing attention when using an electric kettle
- Clean up the scale in time. As we all know, if the electric kettle is burned for a long time, a thick layer of scale will remain on the bottom of the inner pot. If these scales are not cleaned up in time, it is easy to accumulate a lot of calcium carbonate . If you drink it frequently, it is easy to form stones, which will damage your health.
How to clean up scale? Two simple and easy-to-operate methods are provided:
- can use white vinegar and baking soda plus a certain proportion of water, boil the water, and the scale will gradually fall off.
- Pour the tea dregs and hot water into the pot together. After shaking it a few times, let it stand for half an hour, the scale will come off naturally.
- Do not boil the water repeatedly. The usually boiled water may be cold because it was not drunk in time. Many people will press the switch again to boil the same pot of water if it is convenient, but the water that is repeatedly boiled is actually harmful to the human body. Because the water will produce nitrite after it is boiled for the first time, the nitrite in it will increase sharply when it is boiled repeatedly. Long-term use of this water is likely to cause us dizziness, nausea or poisoning.
- Do not drink hot water that has just been boiled. If the boiling water exceeds 60℃, it is easy to damage the oral mucosa. If things go on like this, the continuous damage and repair of wounds can easily cause inflammation and increase the risk of oral cancer. Therefore, it is recommended that you drink less water that is too hot and try to wait until it is cool before drinking.
Summary
The above is the introduction to the electric kettle that I have reviewed and summarized. It may not be comprehensive and detailed enough. It may not be very professional. If you have different opinions, you are welcome to discuss it in the comment area. Generally speaking, I think the electric kettle greatly facilitates our daily life. As long as we buy qualified and regular products, it will not harm our health.
