The range hood is now indispensable for cooking and cooking in every household. With it, the oil fume in the kitchen can be discharged outside in time, so that we can breathe clean air. But sometimes we will find that the range hood is obviously good, but the smoking effect is not ideal. Why?

1. Too many bends in the smoke exhaust pipe should be discounted even in strong wind: generally, only one bend is allowed in the smoke exhaust pipe of the range hood, and if there are too many bends, it will lead to poor oil smoke discharge path. It's like running, sprinting in a straight line at the same distance is definitely much faster than all kinds of corners. In addition, the standard stretching length of the smoke tube of the range hood is 1.5 meters. If the length is too long, especially more than 3 meters, it will definitely affect the smoking effect.

2. Narrow or blocked flue in the public * * *: This situation is generally common in some old residential areas. Because the diameter of the flue is designed to be too small, coupled with the accumulation of soot for years, the flue is almost blocked. Then think about it, the flue of the house is blocked, and the suction of the range hood is no matter how big it is. So in this case, contact the residential property to clear the flue.

3. The air convection is too large or the space is too closed: the work of the range hood needs to keep the air flowing indoors. If you close the doors and windows of the kitchen when cooking, the air resistance will increase when the impeller of the range hood rotates, which will lead to the poor smoking effect. However, if you open the doors and windows, in windy weather, it will lead to excessive air convection and blow away the lampblack, which will also affect the smoking effect. Therefore, the correct way is to open the door or window of 5-11cm when using the range hood.

4. There is a lot of oil in the hood: some users have used the hood at home for five or six years and have never cleaned it. There is a lot of oil in the flue system of the hood, which leads to a decrease in suction.

Of course, this situation has something to do with the frequency and quality of use of the hood. For example, your family seldom cooks or cooks, or uses little oil, so it will be much better. In addition, if the quality of your cigarette machine is good and the oil separation is high, the oil accumulation inside the cigarette machine will be much better than that of the cheap brand-name machine.
