厨房每日三餐煎炒烹炸，是个油烟重地，怎么设计排烟罩是个大问题，关系到卫生和身体健康。在每个细节上多动点脑筋，就会收到很大的效果。
Cooking three meals a day in the kitchen is a place with heavy cooking fume. How to design a smoke hood is a big problem, which is related to health and health. If you think more about every detail, you'll get great results.
油烟机要安在背风的一面墙下。跟前没有大风吹过，风不会回灌。保证油烟顺利被吸走。
First of all, the range hood should be installed under the leeward wall. There is no strong wind in front of me, and the wind will not recharge. Make sure that the lampblack is sucked away smoothly.
要给油烟机下面装一个灶柜，这样油烟直接就被吸上去了。
To install a stove under the lampblack machine, so that the lampblack is directly sucked up.
油烟机的位置要离窗户近，这样安装的通风管道会更短，能更快地排出室内。
The location of range hood should be close to the window, so that the installation of the ventilation duct will be the shortest and can be discharged into the room faster.
管道从油烟机到排风口的管道要平直或稍微上扬，不要往下降方向走，保证风的走势顺畅。
The pipeline from the range hood to the exhaust outlet shall be straight or slightly upward, and shall not go downward to ensure the smooth trend of wind.
塑料管道一定要尽可能粗，排风量才大。
The plastic pipe must be as thick as possible so that the exhaust air volume is large.
因为是塑料管道，排烟时很容易摇晃，更好用绳子绑住管道，挂在房顶上，一是承受一部分管道的重量，二是帮助稳定管道不致来回晃。
Because it is a plastic pipe, it is easy to shake when smoke exhaust. It is best to tie the pipe with a rope and hang it on the roof. First, it can bear the weight of part of the pipe, and the second is to help stabilize the pipe from swinging back and forth.
为了防止露在室外的管道进入小鸟或飞虫，在管道口安上一个用纱布围起来的布兜，排烟时，布兜自动撑开，不排烟时，布兜就落下去，挡住了风口。只要这些小细节上注意了，排烟效果就明显增强了。
In order to prevent the outdoor pipeline from entering into birds or insects, a cloth pocket surrounded by gauze is installed at the pipe opening. When smoke is exhausted, the cloth pocket will automatically open, and when there is no smoke exhaust, the cloth pocket will fall down and block the air outlet. As long as these small details are paid attention to, the smoke exhaust effect will be significantly enhanced.
