The material of sound absorption function.
Further, the thickness of the abatvoix is 1-500mm, and the abatvoix in this size range annexs good work
Skill and sound-absorbing effect are suitble to Product industrialization.
Further, in the abatvoix towards the coating for being coated with waterproof and oilproof on one side of the wind turbine.Waterproof and oilproof
Coating can prevent inside oil smoke and water stain intrusion abatvoix, prevent abatvoix from failing.
Further, the coating of waterproof and oilproof is coated in all outer surfaces of the abatvoix.In the whole of abatvoix
The coating that outer surface is coated with waterproof and oilproof can further improve the waterproof and oilproof performance of abatvoix, extend the use of abatvoix
Service life.The coating can be nano-macromolecule material, such as fluorine carbon composite, the painting that nano-macromolecule material is utilized to be formed
Oil or water gear cannot be penetrated coating by the tension of layer surface outside coating.
Another purpose of the utility model is to reduce the reverberation that fan noise generates in babinet, for this purpose, described
Top plate is equipped between abatvoix and air outlet seat, at least provided with an exhausting hole on the top plate, the mounting of roof plate is in the case
On body.The purpose of setting through-hole can further eliminate the noise passed through by abatvoix, and extra noise can be out of hole
It passes through, toward babinet external radiation, reduces since the noise that wind turbine generates is in the reverberation of box house, so as to reduce from the bottom of box
The noise of cooker is passed to from air intake so that cooker culinary art comfort level carries.
Further, the through-hole is round, rectangular either oval and round, rectangular or oval combination.
Certainly it may also be the shape that other people in the art know.
Compared with prior art, the beneficial effects of the utility model：
(1) abatvoix in the utility model can eliminate the noise of blower fan work process generation, promote culinary art comfort level.
(2) waterproof and oilproof coating is coated on the abatvoix in the utility model, prevents abatvoix corrosion failure, extend suction
The service life of soundboard.
(3) top plate in the utility model is micropore harden structure, is applied in combination, can greatly reduce in babinet with abatvoix
Existing reverberation.

Specific embodiment
Embodiment 1
Referring to Fig. 1-5, the denoising structure of range hood includes babinet 1, the wind turbine 2 being arranged in babinet 1, by can in Fig. 2
To find out, air inlet 21 and the spatial relation of air outlet 22 of wind turbine 2 are vertical, and oil smoke is inhaled into from air inlet 21,
It is discharged from air outlet 22.Referring to Fig. 1 and Fig. 3, air outlet seat 3 is installed on the top plate 4, and top plate 4 then forms one of babinet 1
Point, it may also be said to it is that top plate 4 is mounted on babinet 1.Top plate 4 is equipped with an exhausting hole 41, and through-hole 41 is circular through hole, aperture
Less than or equal to 1.0mm.As can be seen from Figure 3 on the top plate 4 substantially be covered with through-hole 41, in addition to some mounting holes with
Outside.Referring to Fig. 2, Fig. 4 and Fig. 5, abatvoix 5 is equipped between top plate 4 and babinet 1, abatvoix 5 is made of sound-absorbing material, than
Such as acoustical cotton, foamed plastics, aluminum fiber cotton, single-layer polyester cellucotton, plant cellulose sprayed on material or centrifugally glass-wool
Material.The all surface of abatvoix 5 is coated with the coating 41 of one layer of Water-proof and oil-proof, and coating 41 can prevent oil smoke and water stain
The inside of abatvoix 5 is invaded, prevents abatvoix 5 from failing, coating 41 can be nano-macromolecule material, such as fluorine carbon composite wood
Material, the tension on 41 surface of coating formed using nano-macromolecule material is kept off oil or water cannot penetrate coating outside coating
41.The visually specific actual conditions selection of the thickness of abatvoix 5 provides the range of a comparison optimization, the thickness of abatvoix 5 here
In 1-100mm, the resultant effect of acquirement is relatively good.The noise that the operation of wind turbine 2 generates can absorb part by abatvoix 5, separately
An outer part is further absorbed by through-hole 41, and another part passes through top plate 4, is radiated the top of babinet 1, this structure energy
Reduce the reverberation inside the noise generated due to wind turbine 2 and babinet 1.Since cooker is located at the bottom of babinet 1, it is possible to reduce make an uproar
Injury of the sound to cooker, while waterproof and oilproof coating 41 can protect abatvoix 4 to fail from oil smoke and water stain intrusion.
Referring to Fig. 8, fan installing structure of the prior art just without decrease of noise functions, that is, lacks abatvoix 5 compared to the utility model
It is different with the structure and the structure of the utility model top plate 4 of top plate 6.
Embodiment 2
Embodiment 2 and the structure of embodiment 1 are essentially identical, unlike embodiment 2 abatvoix 5 only towards wind turbine 2
Outer surface be coated with the coating 51 of waterproof and oilproof, in this way can cost-effective and material, but the part for sacrificing abatvoix 5 is prevented
Grease performance.
The technical solution of the utility model and advantageous effect is described in detail in the upper specific embodiment, should
What is understood is the most preferred embodiment the foregoing is merely the utility model, is not intended to limit the utility model, all in this reality
With any modification, supplementary, and equivalent replacement done in novel spirit etc., the protection of the utility model should be included in
Within the scope of.
