专注通风管道加工·排烟罩

管道位置。以公共壁炉通风口为例，在装修厨房之前，应仔细调查公共壁炉的位置，以确定合理的壁炉安装位置。烟囱安装的高度和方向，底座的方向，烟囱如何行进，如何弯曲，进入吊顶，横梁和墙壁都要仔细规划。

Pipe location. Take the vent of public fireplace as an example. Before decorating the kitchen, the location of public fireplace should be carefully investigated to determine the reasonable installation location of fireplace. The installation height and direction of the chimney, the direction of the base, how the chimney moves, how to bend, and how to enter the ceiling, beam and wall should be carefully planned.

管道长度。开口越靠近公共烟道，管道对排烟的影响越小，排烟越亮。管道长度可控制在2米以内。1.5米以内为佳。烟道的开口位置也提前规划好了，烟管不长但高一点，把烟管封在天花板上，这样烟管容易排烟，既能兼顾美观的同时，也减少了挂箱的空间。

Pipe length. The closer the opening is to the public flue, the smaller the impact of the pipe on the smoke exhaust and the brighter the smoke exhaust. The pipe length can be controlled within 2m. Within 1.5m is preferred. The opening position of the flue has also been planned in advance. The flue pipe is not long but a little higher. The flue pipe is sealed on the ceiling, so that the flue pipe is easy to smoke, which can not only give consideration to the beauty, but also reduce the space for hanging the box.

避免家用电器。济南厨房排烟管道应远离电缆，应避开各种家具、电气设备、天花板和墙壁上的障碍物。所以，如果不是关于之前房间的改造，要确定烟管的方向，然后稳定烟机周围的吊箱。

Avoid household appliances. The smoke exhaust pipe of Jinan kitchen shall be far away from cables, and shall avoid obstacles on various furniture, electrical equipment, ceilings and walls. Therefore, if it is not about the transformation of the previous room, first determine the direction of the smoke pipe, and then stabilize the hanging box around the smoke machine.

送风风量一般为排烟风量的80%，当厨房处于一层或门窗较多自然补风量充足时，可适当减小这个数值，但少不能小于排烟风量的65%。只有排烟风量和送风风量达到平衡，才能保证厨房排烟效果。

The air supply volume is generally 80% of the smoke exhaust volume. When the kitchen is on the first floor or there are many doors and windows and the natural air supplement volume is sufficient, this value can be appropriately reduced, but not less than 65% of the smoke exhaust volume. Only when the smoke exhaust air volume and air supply air volume are balanced can the smoke exhaust effect of the kitchen be ensured.

此外厨房排烟管道时的施工细节要注意，管道越短越好。一些业主会为了美观，把管道拉得比较长，这样一来，关掉油烟机后，管道里还会集聚很多油烟排不出去，再倒回室内。另外，为了不破坏原有的主副烟道，其开口方向不是随意可以改的，一定要打在副烟道里面。

In addition, pay attention to the construction details of the kitchen smoke exhaust pipe. The shorter the pipe, the better. Some owners will lengthen the pipeline for the sake of beauty. In this way, after the range hood is turned off, a lot of oil smoke will accumulate in the pipeline and cannot be discharged, and then it will be poured back indoors. In addition, in order not to damage the original main and auxiliary flue, the opening direction can not be changed at will, and must be placed in the auxiliary flue.

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。在窗户或墙面开洞之前一定要经过物业的同意；其次注意问题，一般排烟管末端是金属材质的，如果开的洞太小，金属传热可能会使玻璃炸裂，伤及行人，且烟管通向窗外，强劲的北风对着吹会导致油烟倒灌。好将管道伸出去以后把管道往下窝，这样还可以避免下雨时雨水流进管道，并把风挡在外面。

In order to avoid the problem of cross smoke, some owners give up the original flue and directly open holes in the windows for smoke exhaust. This is OK, but there are several points that need to be paid attention to. 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. After the pipe is stretched out, the pipe is lowered into a nest. In this way, the rain water can be prevented from flowing into the pipe when it rains, and the windshield is kept outside.
