現在很多家庭都安裝了抽油煙機等排煙設備，但一直未能解決廚房油煙問題。不是抽油煙機沒用，而是安裝不到位，導致抽油煙機無法發揮很大的作用。那么廚房排氣不夠強怎么辦呢？以下是您必須注意的一些事項的列表。

Now many families have installed smoke exhaust equipment such as range hoods, but they have not been able to perfectly solve the problem of kitchen smoke. It is not that the range hood is useless, but that it is not installed in place, which makes the range hood unable to play a great role. So what if the kitchen exhaust is not strong enough? Here is a list of some things you must pay attention to.

必須保留輔助煙道

Auxiliary flue must be retained

每個廚房都有煙道，但你知道還有主煙道和副煙道嗎？主煙道貫穿整個建筑。輔助煙道相對獨立。用帶孔的隔板與主煙道隔開，上下用地板密封。一般家里的油煙都會先到副煙道做緩沖，再通過隔板上的小孔進入主煙道，這樣才能保證每戶的油煙都是隔離的，不會被熏制。

Every kitchen has flues, but do you know there are also main flues and auxiliary flues? The main flue runs through the whole building. The auxiliary flue is relatively independent. It shall be separated from the main flue with perforated clapboard, and the upper and lower parts shall be sealed with floor. Generally, the lampblack in the home will be buffered in the auxiliary flue first, and then enter the main flue through the small hole on the partition, so as to ensure that the lampblack in each household is isolated and will not be smoked.

主、副煙道必須同時存在。部分業主家中出現冒煙或雜煙現象，很可能是裝修時排煙管與主煙道連接錯誤，或為節省空間而拆除了輔助煙道。如果直接與主煙道相連，由于其強大的向上吸力，堪比“拔罐效應”。一旦氣壓比較低，它可能會將其他家的油煙壓到自己家。輔助煙道緩沖效果好，不能拆除。

The main and auxiliary flue must exist at the same time. Smoke or Miscellaneous smoke appears in some owners' homes, which is likely due to the wrong connection between the smoke exhaust pipe and the main flue during decoration, or the removal of the auxiliary flue to save space. If it is directly connected with the main flue, it is comparable to the "cupping effect" due to its strong upward suction. Once the air pressure is low, it may press the lampblack from other homes to its own home. The auxiliary flue has good cushioning effect and cannot be removed.

注意施工細節

Pay attention to construction details

選擇抽油煙機的安裝位置非常重要。確保管道盡可能短。有的業主為了美觀會把煙管加長。這樣，抽油煙機關閉后，很多油煙會積聚在管道中，無法排出，然后又倒回室內。

It is very important to select the installation position of the range hood. Make sure the pipe is as short as possible. Some owners will lengthen the smoke pipe for the sake of beauty. In this way, after the lampblack exhausting mechanism is closed, a lot of lampblack will accumulate in the pipeline and cannot be discharged, and then it will return to the room.

另外，為了不損壞原主副煙道，開口的開口方向不能隨意改變，必須在副煙道內打。車主不能根據自己的喜好隨意更改。但煙道的孔可以擴大，但要注意不要損壞二級煙道的擋板。

In addition, in order not to damage the original main and auxiliary flue, the opening direction of the opening cannot be changed at will, and it must be punched in the auxiliary flue. The car owner cannot change it at will according to his own preferences. However, the hole of the flue can be enlarged, but care should be taken not to damage the baffle of the secondary flue.

止回閥經常更換

Check valves are frequently replaced

濟南廚房排煙廠家認為如果您已經拆除了輔助煙道，或者需要更好地防止煙霧倒出，建議您使用煙道止回閥。很多車主會質疑為什么抽油煙機已經有止回閥，為什么還要安裝煙道止回閥？

Jinan kitchen smoke exhaust manufacturer thinks that if you have removed the auxiliary flue or need to better prevent the smoke from pouring out, experts recommend you use the flue check valve. Many car owners will question why the range hood already has a check valve and why the flue check valve should be installed?

一般來說，抽油煙機的止回閥不是很有效，但是在煙道中安裝一個止回閥可以保護抽油煙機，使煙道內的煙霧不會倒進煙管和抽油煙機。但安裝止回閥后，應定期清洗，否則止回閥會打開而失去作用。并且煙道止回閥非常好，應該每兩年左右更換一次。

Generally speaking, the check valve of the range hood is not very effective, but installing a check valve in the flue can protect the range hood, so that the smoke in the flue will not fall into the smoke pipe and range hood. However, after the check valve is installed, it should be cleaned regularly, otherwise the check valve will open and lose its function. And the flue check valve is very good and should be replaced every two years or so.
