Embodiment Construction
[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] see figure 1 One end of the smoke exhaust pipe 100 of the present invention is connected to the air outlet of the range hood 200, and the other end is connected to an outdoor public flue (not shown). With the smoke exhaust pipe 100 of the present invention, after bending, there is no need to add fixing parts and restraining parts, and the pipe itself has enough rigidity to maintain the arrangement shape.
[0027] see Figure 2 to Figure 7 , The smoke exhaust pipe 100 includes at least two single-section mufflers 1, and each single-section muffler 1 is connected end to end. Each single-section muffler 1 includes a sound-absorbing pipe 11 and a fireproof and noise-reducing layer 12, wherein the sound-absorbing pipe 11 is made of high-temperature-resistant and corrosion-resistant materials, such as fluoroplastics or stainless steel. The...

The invention discloses a smoke exhaust pipe suitable for range hoods, which is characterized in that: the smoke exhaust pipe includes at least two single-section mufflers connected end to end, each single-section muffler includes a sound-absorbing pipe, and the adjacent A universal movable joint structure is formed between the two sound-absorbing pipes. Compared with the prior art, the present invention has the advantages of adopting a structure in which a plurality of single-section mufflers form a universal movable joint connection structure to form a smoke exhaust pipe, which can be free from positioning and adjust the bending of the smoke exhaust pipe arbitrarily according to the user's use environment Radius, after the smoke exhaust pipe is arranged, there is no need to add fixing parts and restraints. The pipe itself is rigid to maintain the layout shape. In a complex installation environment, a more reasonable smoke pipe layout is guaranteed. When the range hood is running, the pipe is not easy to shake , to prevent the generation of vibration and noise, and the smoke exhaust resistance at the outlet of the range hood is small, ensuring the best smoking effect of the range hood.
Description
technical field [0001] The invention relates to a lampblack purifying device, in particular to a smoke exhaust pipe suitable for range hoods. Background technique [0002] The range hood is one of the essential kitchen equipment in modern families. The exhaust pipe of the range hood is a pipe that transports the oil fume to the public flue of the building, and is an important part of the range hood. The radiated noise of the range hood under standard measurement conditions has been basically determined at the factory, but the user needs to install a smoke exhaust pipe to discharge the oil fume outside, or exhaust the smoke to the public flue through the smoke exhaust pipe, and the noise inside the range hood Propagated and amplified through the pipeline. At this time, the radiated noise of the range hood will change significantly, and abnormal sound may be generated, and the noise level will increase. [0003] In addition, after the exhaust duct is installed at the outlet...
