Abstract
The utility model discloses a noise reduction tube of an environmentally-friendly smoke hood. The noise reduction tube comprises a tube body, wherein an inner sleeve layer is arranged in the tube body; multiple small holes are distributed in the inner sleeve layer; the end part of the tube body is connected with the end part of the inner sleeve layer; a hollow structure is formed between the tube body and the inner sleeve layer; an air vent of the inner sleeve layer is used as the air vent of the tube body; a micro-hole baffle is arranged in the inner sleeve layer along the length direction of the tube body. According to the noise reduction tube of the environmentally-friendly smoke hood, the tubes for a range hood are modified to be of a reasonable structure, particularly a cavity is formed between the tube body and the inner sleeve layer and is matched the micro-hole baffle, so that the passing oil smoke is dispersed to form relatively turbulent flow, the vibration caused when the oil smoke passes through an oil smoke tube is alleviated, noise can be effectively reduced without sound isolation materials and the safety potential hazards caused by the flammable sound isolation materials is avoided; the noise reduction tube of the environmentally-friendly smoke hood is simple in structure and convenient to manufacture and is favorable for technical popularization and application.
Description
Technical field
The utility model relates to automatic-cooking field, particularly a kind of for eliminating the noise-reducing pipe of lampblack absorber noise.
Background technology
Lampblack absorber is a kind of common electric that purifies kitchen environment.It is mainly responsible for the harmful oil smoke producing in the refuse of cooking stove burning and cooking process to take away rapidly, outside discharge chamber, reduces and pollutes, and purifies air, for cooking automation and innoxious important role.
At present, existing lampblack absorber noise is still too large.The vibrations that produce when wherein cooking fume is discharged through fume tube are one of them important noise sources.But because lampblack absorber is to work, therefore can not simply rely on acoustic material noise-reducing under the environment of heavy wool cigarette and high temperature, otherwise those inflammable acoustic materials itself can form potential safety hazard to kitchen environment.Therefore, how can reduce safely and effectively noise, improve clean oil smoke effect, become the problem that those skilled in the art need solve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of petticoat pipe noise-reducing pipe of safer environmental protection.
The utility model solves the technical scheme that its technical problem adopts:
Environmental protection petticoat pipe noise-reducing pipe, comprise body, in described body, be provided with inner sleeve layer, on described inner sleeve layer, be distributed with aperture, wherein said body end is connected with the end of inner sleeve layer, between described body and inner sleeve layer, be hollow structure, the ventilating opening of described inner sleeve layer, as the ventilating opening of body, is provided with microporosity separator along body length direction in described inner sleeve layer.
As a preference, described microporosity separator is hollow structure.
As a preference, described each microporosity separator is arranged in parallel.
As a preference, the end of described microporosity separator is provided with inclined-plane.
As a preference, the end of described body is provided with for hard-wired turnup structure, and described turnup structure is around the mouth of pipe of body.
The beneficial effects of the utility model are: this lampblack absorber passes through reasonably structure improved with pipe, particularly body and inner sleeve layer form an inner chamber, coordinate with microporosity separator, make to be dispersed into relatively mixed and disorderly flow-disturbing by cooking fume, the vibrations that produce when alleviating cooking fume through fume tube, thus noise, the potential safety hazard of also avoiding inflammable acoustic material to bring in the situation that not needing acoustic material, effectively reduced, and simple in structurely easily make, be conducive to applying of technology.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model;
Fig. 2 is plan structure figure of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, environmental protection petticoat pipe noise-reducing pipe, comprise body 1, in described body 1, be provided with inner sleeve layer 2, on described inner sleeve layer 2, be distributed with aperture, wherein said body 1 end is connected with the end of inner sleeve layer 2, between described body 1 and inner sleeve layer 2, is hollow structure, be between body 1 and inner sleeve layer 2, to form the inner chamber of a relative closure, and gas can enter this inner chamber by the aperture from inner sleeve layer 2.The ventilating opening of described inner sleeve layer 2, as the ventilating opening of body 1, comprises the air inlet of pipeline and the two ends that air outlet lays respectively at body 1.In described inner sleeve layer 2, along body 1 length direction, be provided with microporosity separator 3, on microporosity separator 3, be distributed with equally micro hole.This microporosity separator 3 can play and disturb the mobile flow-disturbing that forms of cooking fume.Wherein, as a preference, described microporosity separator 3 is hollow structure, and gas can enter from the aperture of microporosity separator 3 in the microporosity separator 3 of hollow, further improves flow-disturbing effect.
Should be noted that, the shape of body 1 needs according to pipeline actual installation and fixed, can need to extend or bending according to actual design, and not necessarily with shown in accompanying drawing, be limited.Body 1 also can be designed to circular or square, and microporosity separator 3 also can be designed to a plurality of petal-shaped and arrange.And as preference, described each microporosity separator 3 is arranged in parallel, such flow-disturbing effect is better, and noise-reducing effect is better.
The end of described microporosity separator 3 is provided with inclined-plane 4, and this inclined-plane can play the effect of guiding air-flow, can reduce the noise sending when clash into cooking fume and microporosity separator 3 ends.
The end of described body 1 is provided with for hard-wired turnup structure 5, and described turnup structure 5, around the mouth of pipe of body 1, is convenient to the installation of pipeline.
During specific works, cooking fume is from the air inlet of body 1, and the air inlet of inner sleeve layer 2 goes out to enter.The inner chamber that in way, cooking fume enters between body 1 and inner sleeve layer 2 from inner sleeve layer 2 aperture forms flow-disturbing, and cooking fume also forms flow-disturbing under the effect of microporosity separator 3 more simultaneously, changes original cooking fume current stabilization state.The vibrations that these flow-disturbings produce when can effectively alleviate cooking fume through fume tube, thus noise can in the situation that not needing acoustic material, effectively be reduced.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned embodiment.Therefore, the utility model is not limited to the specific embodiment disclosed and described above, to modifications and changes more of the present utility model, also should fall in the protection domain of claim of the present utility model.
Through facts have proved, this lampblack absorber forms an inner chamber with pipe by body 1 and inner sleeve layer 2, coordinate with microporosity separator 3, the vibrations that produce when effectively alleviating cooking fume through fume tube, can in the situation that not needing acoustic material, effectively reduce noise, also the potential safety hazard of avoiding inflammable acoustic material to bring, and simple in structurely easily make, be conducive to applying of technology.
