窗户排烟注意安全
Pay attention to safety when smoke is discharged from windows
一些业主为了避免串烟问题，放弃原有烟道，直接在窗户上开孔排烟，这样做是可以的，但有几点需要注意。

First, the consent of the property must be obtained before opening a hole in the window or wall; Secondly, pay attention to safety. Generally, the end of the smoke exhaust pipe is made of metal. If the hole is too small, the metal heat transfer may cause the glass to crack and hurt pedestrians. In addition, the smoke pipe leads to the window, and the strong north wind will cause the oil smoke to pour back. It is best to stretch out the pipe and then nest it down. In this way, it can also prevent the rain water from flowing into the pipe when it rains and keep the wind shield outside
