The smoke pipe of range hood is typically all to use telescopic plastic circular pipeline or aluminium foil circular pipe at present, this
At least there is following deficiency in class flexible pipeline:
1, it is rough inside it and has fold, air-flow is caused to have some setbacks；
2, smoke pipe is relatively thin, and when use is easy to happen smoke pipe bending, flue length can be made to increase in this way, resistance also can accordingly add
Greatly；
3, the bending place of smoke pipe is likely to form indentation section, can generate oil accumulation, after the time has been grown, the greasy dirt weight of accumulation
Greatly, it will lead to smoke pipe deformation；
4, it is inadequate to result in intensity at wrinkle for this smoke pipe manufacture craft, and smoke pipe compares appearance for a long time by air-flow impact force
It easily ruptures, leads to gas leak of the oil leakage, and intensity is inadequate, the noise for also resulting in gas shock generation is larger.
In addition, using the smoke pipe of original length without exception regardless of smoke machine air outlet size with a distance from common air flue check valve
It is installed, such as this body length of smoke pipe is between 1.5-2m, when smoke machine air outlet seat only has 0.6m from common air flue check valve
Apart from when, original smoke pipe can't be cut out lower 0.6m length and installed by existing mounting means, but directly by original smoke pipe
Extra smoke pipe is partially compressed and fixes by installation, and compression fixed part internal diameter is smaller than the smoke pipe internal diameter of stretching, leads to resistance significantly
Increase, air-flow is unsmooth, has seriously affected smoke discharging effect.
