Many owners are annoyed by the smoke stringing or poor smoke exhaust in the kitchen at home. I thought the range hood was not awesome, but the editor reminds you that such a situation has a lot to do with the method of installing the smoke exhaust pipe for the first time. Here, let's talk about the necessity of the existence of the main and auxiliary flue in the kitchen smoke exhaust decoration.
The auxiliary flue must be kept.
There are flues in every kitchen, but do you know there are main and auxiliary flues? The main flue runs through the whole building. The auxiliary flue is relatively independent. It is separated from the main flue by a perforated partition, and the upper and lower parts are sealed by the floor. Generally, the lampblack in the home will first go to the auxiliary flue, make a buffer, and then enter the main flue through the hole on the partition, so as to ensure that the lampblack of each household is isolated and will not cross the smoke.
The main and auxiliary flue must exist at the same time.
The phenomenon of smoke pouring or smoke stringing in some owners is likely to be due to the wrong connection between the smoke exhaust pipe and the main flue during decoration, or the removal of the auxiliary flue in order to save space. If it is directly connected to the main flue, it can be compared to the "cupping effect" because of its great upward suction. Once the air pressure is relatively low, it may press other families' oil smoke to their own homes. The auxiliary flue has a good buffer effect, so it cannot be removed.
On the forum, I saw some owners' introduction that the smoke exhaust effect of the house is not good. So he smashed the auxiliary flue, and then bent the smoke pipe up 45 degrees, so as to eliminate the problem of partial smoke return. Is this really OK? Jinan kitchen smoke Xiaobian suggested not to use this method. Even if the smoke exhaust pipe turns upward, it will still cause smoke and smell in the home. Although the check valve can be used for isolation, if the check valve is not cleaned frequently, it will not be closed tightly, and there will still be smoke and smell. And if everyone uses this method, it will occupy a lot of space in the flue, resulting in poor smoke exhaust.
To solve the problem of cross smell, valves need to be installed. For the kitchen to change the flue, adding a valve at the inlet of the flue is a good way to solve the cross smell. This valve is one-way. When the range hood is working, the valve opens to the flue. When other residents discharge smoke into the flue, the valve will be tightly closed to prevent the smoke from pouring back into the flue, effectively solving the problem of "cross smell".
If you want to change the flue of the kitchen, it is not so easy to change it. You must obtain the consent of the property before changing the flue. There are also certain safety problems. Otherwise, it will cause contradictions in neighborhood meetings.
