1. By connecting the smoke exhaust duct through the upper part of the suspended ceiling, this method does not need to consider the distance between the flue outlet and the wall, effectively avoiding installation problems when the distance between the smoke exhaust duct is greater than the depth of the ceiling cabinet. However, in such installation, it is important to pay attention to the following two points:

首先是要检查烟道口的吊顶安装条件：由于吊顶需要进行下移,所以要考虑上部预留的空间和位置是否具备安装的条件;其次预埋排烟管道时可能会有缝隙，要注意封闭好,以保证管道不会脱落;2、厨房排烟管道可以采用吊柜柜体方式进入设置，这种方法是一种很常见的厨房排烟管道布置方法，这用到的管道也比较少，当然依然要注意几点：

Firstly, it is necessary to check the installation conditions of the suspended ceiling at the flue outlet: as the suspended ceiling needs to be moved downwards, it is necessary to consider whether the reserved space and position on the upper part meet the installation conditions; Secondly, there may be gaps when embedding smoke exhaust pipes, and attention should be paid to sealing them properly to ensure that the pipes do not fall off; 2. The kitchen smoke exhaust duct can be set up through the use of hanging cabinets and cabinets. This method is a common layout method for kitchen smoke exhaust ducts, and the number of ducts used is relatively small. Of course, there are still several points to pay attention to:

(1)直径为2.0~2.2m的管道，烟道口外沿与墙的距离不要超过250mm，因为这样才能保证安装完吊柜后排烟管在煤气表、煤气管道前有足够的空间;(2)相对于欧式油烟机来说，这种布置方式与中式抽油烟机更搭配，因为中式烟机的上部通常都有吊柜柜体，而欧式烟机上部通常不做柜体。所以通常不存在引走管道的空间。

(1) For pipes with a diameter of 2.0-2.2m, it is best not to exceed 250mm from the outer edge of the flue opening to the wall, as this can ensure that there is sufficient space for the exhaust pipe in front of the gas meter and gas pipeline after the installation of the hanging cabinet; (2) Compared to European range hoods, this arrangement method is more suitable for Chinese range hoods because the upper part of Chinese range hoods usually has a hanging cabinet body, while the upper part of European range hoods usually does not have a cabinet body. So usually there is no space to lead pipes away.

3、利用吊顶与吊柜间的空间来接入排烟管道，这种排烟管道设置方法是适用吊顶紧贴厨房顶部户型装修方式，主要是采用吊柜顶部和吊顶之间的空档横向引走排烟管道，也有这样的几点要注意：

3. Using the space between the suspended ceiling and the suspended cabinet to connect the smoke exhaust duct, this method of setting the smoke exhaust duct is suitable for the decoration method of the ceiling closely adhering to the top of the kitchen. The main method is to use the gap between the top of the suspended cabinet and the suspended ceiling to horizontally lead the smoke exhaust duct. There are also several points to note:

(1)厨房排烟管道烟道口的位置必须高于吊柜的顶部，要确保吊顶与吊柜之间有足够的空间;(2)烟道口外部与墙面的距离不能超过吊柜柜体的进深，因为吊柜安装完毕后需要用封顶板将排烟管道封住，如果距离不够操作不方便。

(1) The position of the smoke exhaust duct outlet in the kitchen must be higher than the top of the ceiling cabinet, ensuring sufficient space between the ceiling and the cabinet; (2) The distance between the outside of the flue outlet and the wall should not exceed the depth of the ceiling cabinet body, because after the installation of the ceiling cabinet, it is necessary to seal the smoke exhaust pipeline with a sealing plate. If the distance is not enough, it is not convenient to operate.
