What are the misunderstandings about the use of kitchen range hoods?

With the improvement of people's living standards, people pay more and more attention to catering hygiene and kitchen hygiene, so the range hood has become a necessary appliance in the kitchen. However, do you understand the skills of using the range hood? Now SHINELONG editor will introduce the misunderstandings of using the range hood. Misunderstandings of using the range hood 1. Use the range hood only when cooking. Only turn on the range hood when cooking, and do not turn it on when boiling water or cooking. The function of the range hood is not only to remove cooking fumes, but also to eliminate gas pollution. On the one hand, it is the gas leaked every time the ignition and flameout, and on the other hand, it is the waste gas generated during the combustion of gas, especially liquefied petroleum gas, which is more harmful to health than cooking fumes. Correct approach: Whenever the kitchen stove is used, the range hood should be turned on, and the kitchen windows should be careful not to close to ensure the normal flow of air, so that the range hood can work better. 2. Turn off the range hood immediately after the meal is ready. Many people like to turn off the range hood as soon as the meal is cooked. In fact, this is not possible. Although the range hood will consume some electricity when it is turned on, if you turn off the range hood immediately, the remaining fumes in the kitchen will not be sucked away, causing the kitchen to become greasy. The correct approach: Avoid residual gas in the kitchen after cooking. Wait for 5-6 minutes before turning off the range hood to create a smoke-free environment in the kitchen. 3. Clean the surface only. After using the range hood for a period of time, it is inevitable that a lot of oil stains will accumulate. However, when most people clean the range hood, they only clean the surface of the range hood and do not clean the inside. When the oil stains stick to the motor shaft, it will invisibly increase the friction and increase the motor load. The long-term accumulation and oxidation of oil stains to form acidic substances will corrode the range hood. In addition, the long-term accumulation of oil stains inside the range hood and the flue may also pose a fire hazard. The oil stains on the impeller and flue increase the viscosity, making the exhaust unsmooth, increasing the spread of oil smoke in the kitchen space, and endangering human health. Correct approach: For the inside of the range hood, it is recommended to ask a professional cleaning staff to clean it every 3-5 months. This will not only eliminate many safety hazards, but also protect your health. 4. When using a range hood in a closed environment, many people have such a misunderstanding that when using a range hood, the doors and windows must be closed to make the range hood work better. In fact, this is not the case. When exhausting oil smoke, if fresh air is not replenished in time, it is not conducive to the combustion of gas. Correct approach: When using a range hood, you should open the windows for ventilation, or use an exhaust fan to replenish fresh air, but you cannot let the air in the kitchen form convection ventilation, because this will affect the suction of the range hood and affect the exhaust effect! The above is all about the misunderstandings of the use of kitchen range hoods. If you want to ensure that the range hood can operate normally, you must remember to clean the range hood regularly!
