What to do if the kitchen flue is too longHow long is the length of the kitchen flue?

The kitchen is too far away from the common flue, resulting in the kitchen flue being too long and needs to be dealt with according to the actual situation.

Situation 1: If it is directly discharged to the outdoors, it is easier to solve.

Choose a range hood with a large air volume, if there is no limit to the size, it is recommended to choose a European-style hood (also known as direct suction), the effect of direct suction is much higher than that of side suction in the case of the same suction, it is a closed kitchen, and if you don't stir-fry food, the distance of 3 meters is basically no problem.

Situation 2: If it is connected to a public flue, it is more complicated.

There will be a public flue of fume backfilling, but there is still a solution is to install a check valve at the flue mouth of the hood, the hood will open when it is working, and it will automatically close when it does not work, and the fume in the public flue will not enter the kitchen, in addition, it should be noted that the best distance between the range hood pipe and the flue is, if it exceeds 3m, it will definitely affect the working effect of the range hood, and the closed kitchen is okay, if it is an open kitchen, cooking such as stir-frying is basically not considered.

Situation 3: If the distance to the public flue is more than 2 meters.

It can be considered to install a relay device between the two smoke exhaust pipes, which is an air supply device to ensure the overall exhaust capacity. Regarding the check valve, the general smoke machine is not with, generally to the range hood manufacturer related after-sales purchase, thickened with gasket smoke machine check valve price is about 30 yuan, 50 yuan of material is relatively good, and 150 160 180mm universal (with adjusting head).

Note: If you plan to save costs, if you install a hose directly in the kitchen to connect to the flue above the integrated ceiling, it will not have a big impact in the short term, but it is easy to cause oil smoke backflow and blockage after a long time. Due to the long distance of the hose transversely, the oil smoke will form an oil pile on the pipe wall, which will affect the smoke exhaust effect for a long time, and the pipe should not turn too much, and it is best to remove the pipe every one or two years to clean it or replace it with a new one.

The length of the smoke exhaust pipe is calculated as the nearest straight line distance from the top of the smoke machine to the public flue mouth, and it should be noted that the vertical length (the length of the pipe pipe to the transverse direction of the smoke pipe is also added), and the length attached to the general smoke machine does not exceed 2 meters, which is enough to meet the normal needs.

The length of the smoke exhaust pipe is calculated as the nearest straight line distance from the top of the smoke machine to the public flue mouth, and it should be noted that the vertical length (the length of the pipe pipe to the transverse direction of the smoke pipe is also added), and the length attached to the general smoke machine does not exceed 2000mm, which is enough to meet the normal needs. If this length is not enough, and you want to ensure the smoke exhaust effect, you can install a relay device between the two smoke exhaust pipes, which is an air supply device to ensure the overall exhaust capacity.

Regarding the check valve, the general smoke machine is not with, generally to the range hood manufacturer related after-sales purchase, Taobao thickened with gasket smoke machine check valve price of 25 yuan can be bought, 40 yuan can buy the material is very good, and 150 160 180mm universal (with adjusting head).
