Mounting device for smoke exhaust pipe and range hood applying same

Technical Field

The utility model relates to an oil smoke purifier, especially an installation device for discharging fume the pipe to and use the range hood that has installation device.

Background

The range hood is one of the essential kitchen equipment in modern families, and the smoke exhaust pipe of the range hood is a pipeline for conveying oil smoke to a common flue of a building and is an important component of the range hood. The radiation noise of the range hood under the standard measurement condition is basically determined when the range hood leaves a factory, but when the range hood is actually used by a user, an exhaust pipe is required to be installed to exhaust oil smoke outdoors or exhaust the oil smoke to a public flue through the exhaust pipe, and the noise in the range hood is transmitted and amplified through a pipeline. At this time, the radiation noise of the range hood will change obviously, possibly generating abnormal sound, and the noise level will increase.

In addition, after the exhaust duct is installed at the outlet of the range hood, due to the difference of installation environments of the exhaust duct, the arrangement forms of the outlet air duct assemblies are different, and the resistance curve of each user range hood is different, so that the range hood deviates from a better operation condition, the rotating speed and the internal turbulence of the range hood are obviously changed, and further the radiation noise of the range hood is influenced. The air pipe components are different in arrangement form, the airflow state is complex, the resistance is large, the noise in the air outlet cover is amplified by a complex pipeline, and the caused pipeline noise and resistance are different. This part of the research is often overlooked due to manufacturing and installation cost considerations for cigarette machines.
