Description
Technical field
The present invention relates to fume purifier of fume, especially a kind of smoke exhaust pipe suitable for range hood.
Background technique
Range hood is one of essential cooking apparatus in Modern Family.Range hood smoke exhaust pipe is to convey oil smoke
It is the important component of kitchen ventilator to the pipeline of building common duct.Radiation of range hood under the conditions of canonical measure is made an uproar
Sound has determined substantially when leaving the factory, but user, which needs to install in actual use smoke exhaust pipe, is discharged outdoor oil smoke, or passes through
Smoke exhaust pipe is discharged to common flue, and the noise inside range hood passes through pipe transmmision and amplification.At this point, the radiation of range hood is made an uproar
Significant change will occur for sound, it is possible to produce abnormal sound, noise level increase.
In addition, due to the difference of its installation environment, exporting wind pipe component after range hood exports installation exhaust duct
Arrangement form is different, and the resistance curve of each user's range hood is different, and range hood is caused to deviate from preferably operation work
Condition, significant change occurs for the revolving speed and internal turbulence of range hood, and then influences its radiated noise.The arrangement form of wind pipe component
Difference, air flow condition is complicated, and resistance is big, and the noise in outlet housing is amplified by complicated pipeline, caused duct noise and resistance
It is variant.Since range hood manufacture and installation cost consider that the research of this part is often ignored.
Currently, most of in industry use telescopic aluminum foil pipe, cloth can be arbitrarily bent according to different user environments
It sets, but is difficult fixed, random arrangement, is easy to pierce through, there are a large amount of folds after pipeline expansion.It is sent out by lot of experiments
Existing, arbitrarily arrangement leads to that smoke pipe bending part racing, radius bend be small, smoke evacuation resistance in machine outlet increases, and range hood is caused to exist
There is abnormal sound in low flow rate condition operation, machine；And aluminum foil pipe poor rigidity easily shakes, and causes additional noise.
A kind of smoke exhaust pipe for range hood as disclosed in the Chinese patent application No. is 201810410711.4, packet
Include: the first smoke pipe, the first smoke pipe have the first inlet end and the first outlet side, and the first inlet end is suitable for being connected with range hood；
Connecting bend, connecting bend are suitable on fixed carrier in its vicinity and have the first connecting pin and second connection end, and first connects
End is connect to be connected with the first outlet side；Second smoke pipe, the second smoke pipe have the second inlet end and the second outlet side, the second inlet end with
Second connection end is connected, and the second outlet side is suitable for being connected with the smoke outlet on wall.But its not substantive improvement aluminum foil pipe sheet
Body, in complicated installation environment, the shaking of aluminum foil pipe is still had.
For another example application No. is 201810524688.1 Chinese patents to disclose a kind of smoke exhaust pipe, comprising: flexible smoke pipe, it is soft
Property smoke pipe have and be suitable for the inlet end that is connected with range hood and the outlet side suitable for being connected with common flue entrance；It constrains curved
Head, constraint elbow are set in the outside of flexible smoke pipe and between inlet end and outlet sides, and constraint elbow is suitable for being fixed on it
In neighbouring first vector, for constraining the radius bend of flexible smoke pipe.But its poor universality, if encountering more complex user
Installation environment, installation are excessively complicated, at high cost；Not substantive simultaneously to improve the disadvantage that flexible duct shakes, resistance is big yet.
Summary of the invention
The technical problem to be solved by the present invention is in view of the above-mentioned problems of the prior art, providing a kind of suitable for inhaling
The smoke exhaust pipe of kitchen ventilator exempts to position and the position of pipeline can be kept at runtime not shake, reduces the generation of noise.
The technical scheme of the invention to solve the technical problem is: a kind of smoke exhaust pipe suitable for range hood,
It is characterized by: the smoke exhaust pipe includes at least two end to end single-unit mufflers, each single-unit muffler includes noise reduction
