The kitchen has the same flue, which is particularly inconvenient. How to improve?

There is indeed a problem of cigarette smoke going back and forth. Oil fume is a highly carcinogenic substance, and every family should strictly guard against it. How can we eliminate this hidden danger? Only by reforming the flue can we achieve the goal of not stringing cigarettes. I think there are two ways. The first is horizontal transformation. Theoretically, it can be discharged from the main flue, but in fact, part of the oil fume will enter the auxiliary flue on the 7th and 9th floors from the main flue, and then be discharged to the rooms on the 7th and 9th floors through the range hood. Some people say that the range hood has a check valve, which is true, but in the use of your range hood.

One is the direct exhaust type, and the other requires a 90-degree right-angle cylinder at the lower part when it is discharged outward, so that the exhaust gas will turn and be directly discharged below. Originally, this structure was provided for users on the first floor to prevent waste gas from rushing to passers-by, but if users upstairs installed this turning exhaust fan, they put the stove under the window. The smoke machine ventilates through the window. Everything is settled. You can't go through the window. You can punch holes in the wall and go through it. However, you only need to block the smoke crossing at home.

Because each user has a smoke check valve. The cause of the flue gas channeling problem may be that the flue of * * * is blocked, or your one-way check valve is faulty, or the smoke exhaust equipment at the top is faulty, which may cause flue gas channeling. Unplug the air duct of the range hood and push the flap of the air valve with a chopstick to see if it opens and closes smoothly. If it gets stuck, clean it up or replace it. If there is no check valve, you need to install one, which is not expensive, so you can install it yourself.

The ground floor is supplied with air by an air supply outlet. Its principle is that under the push of the range hood, the smoke from each floor will be discharged into the flue, and due to the effect of smoke temperature, rising buoyancy will be generated in the flue, and the smoke will be discharged from the air outlet of the roof. Generally speaking, flue is divided into main flue and auxiliary flue. The auxiliary flue is used to connect the exhaust holes of various range hoods, and the auxiliary flue of the whole building gathers in the main flue. The main flue is unblocked as a whole, and is responsible for the emission of lampblack in the whole building. When installing the range hood, be sure to punch holes in the auxiliary flue.
