Do you want to turn on the range hood when cooking?

With the development of modern science and technology, there are many household appliances at home. There are air conditioners, washing machines and range hoods. Refrigerator and so on. Then each system has different purposes and functions. The function of refrigerator is cold storage. The washing machine is used to wash clothes, and the range hood is used to smoke the gas that pollutes the human body when cooking.

Many times, some people will say, why do you want to turn on the range hood when cooking? In fact, when we cook, the range hood is used to reduce the gas that still chokes our nose. For example, when cooking, the pepper is put down. If the opportunity of lampblack is not opened, the whole floor will have a very choking smell. Inhaling our lungs for a long time will have a great impact on our lungs. We cook every day. When cooking, use an induction cooker or gas to heat various dishes. When heating food, the gas it will give off must be removed with a range hood, otherwise people who smell the gas will easily cough.

Some people will say that boiling water and cooking are not cooking. Why do you want to turn on the range hood? Our range hood is used to absorb oil fume. It will also eliminate gas pollution. When we light the fire, there will be air leakage, and when there is gas, there will be waste gas, which can also be pumped out through the range hood to reduce the amount of waste gas we inhale.

Boiling water also has some knowledge. Our tap water contains chlorine, and the water does not reach the boiling point, so chlorine will not volatilize into the air, which is harmless to human body. However, if the tap water is boiled for a period of time, the chlorine in tap water will change chemically and become a compound called trihalomethane, which has hepatotoxicity, nephrotoxicity and carcinogenicity. When cooking, we also produce this gas, and trihalomethane will evaporate in large quantities with the increase of temperature. Therefore, when boiling water, soup and porridge at home, you must turn on the range hood and keep the kitchen ventilated, and turn off the fire two minutes after the water boils. After heavy rain, there will be more chlorine in tap water. At this time, it is most necessary to use a range hood. Although there is no choking smell when cooking, you must turn on the range hood.
