How to install kitchen exhaust pipes to prevent odor transfer

The smell of oil smoke in the kitchen is very strong, so the installation of exhaust pipes is very skillful. Today I will talk about how to install exhaust pipes to avoid odor transfer.

1. The auxiliary flue must be retained. Every kitchen has a flue, and the flue is also divided into main and auxiliary flues. The main flue runs through the entire building, while the auxiliary flue is relatively independent. . Generally, the oil fumes in the home will first go to the auxiliary flue, and then enter the main flue through the holes in the partition. This can ensure that the oil fumes in each household are isolated. If the auxiliary flue is directly connected to the main flue, the pressure will be too low, resulting in smoke backflow or smoke stringing.

2. Pay attention to the construction details. The shorter the pipeline, the better. In addition, in order not to damage the original main and auxiliary flues, the opening direction cannot be changed at will, and must be opened inside the auxiliary flue.

3. In order to avoid the problem of cross-smoke, some owners abandon the original flue and directly open holes in the windows to exhaust smoke. This is okay, but there are a few points that need to be paid attention to. First of all, you must obtain the consent of the property owner before opening a window or wall; secondly, pay attention to safety issues. Generally, the end of the exhaust pipe is made of metal. If the hole is too small, the heat transfer from the metal may cause the glass to burst and injure pedestrians. , and the chimney pipe leads to the window, the strong north wind blowing against it will cause the oil smoke to pour back. It is best to extend the pipe and then tuck it down. This can also prevent rainwater from flowing into the pipe when it rains and keep the wind out.
