Abstract
The invention relates to a range hood with a noise reduction mask. The range hood comprises a wind cabinet, wherein an overhauling opening is formed in the front end face of the wind cabinet; the noise reduction mask is arranged on a cleaning opening; the noise reduction mask comprises a mask body; the mask body is in a U-shaped structure; a noise reduction plate is arranged between two parallel side edges of the mask body; the noise reduction plate comprises a plate body; the plate body comprises a metal plate layer and a noise reduction cotton layer which are stuck to form a whole body; the thickness of the metal plate layer is 1-3 times as much as the thickness of the noise reduction cotton layer; small holes are densely formed in the plate body; the small holes are arrayed in a mutual staggered manner. A noise reduction panel is arranged so that a function of reducing noises of airflow from the cleaning opening can be realized, and the noises generated by the range hood are reduced.
Description
Technical field
The present invention relates to a kind of lampblack absorber with sound-absorptive face mask.
Background technology
In existing lampblack absorber, comprise wind cabinet, in wind cabinet, spiral case is set, often a clean mouth is offered at wind cabinet front end face for convenience of cleaning wind cabinet inner spiral casing, and installation one piece of face shield on clean mouth, the function of face shield was only as blocking use in the past, and did not possess the function reducing lampblack absorber noise.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of lampblack absorber with sound-absorptive face mask.
The technical solution adopted for the present invention to solve the technical problems is: a kind of lampblack absorber with sound-absorptive face mask, comprises wind cabinet, and the front end face of described wind cabinet is provided with access hole, and described clean mouth is provided with sound-absorptive face mask;
Described sound-absorptive face mask comprises mask body, and described mask body takes the shape of the letter U structure, is provided with acoustical panel between described mask body two parallel sides;
Described acoustical panel comprises plate body, and described plate body includes the sheet-metal layers and silencing cotton layer that are bonded as one, and the thickness of described sheet-metal layers is 1-3 times of silencing cotton layer thickness, described plate body is densely covered with aperture, the interlaced arrangement of described aperture.
Further, the wind of described clean mouth upper end arranges upper sealing plate cashier's office in a shop, and the wind of described access hole lower end arranges lower shrouding cashier's office in a shop.
Further, the lower end of described wind cabinet connects air intake cover.
Further, the thickness of described sheet-metal layers is 2 times of silencing cotton layer thickness.
Further, parallel between described acoustical panel and the base of mask body.
Further, the front end of described mask body two parallel sides is provided with the profile of convex.
The invention has the beneficial effects as follows: rely on the noise reduction panel arranged, the function of noise reduction can be realized the air-flow gone out from clean mouth, reduce the noise that lampblack absorber produces.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the schematic diagram of lampblack absorber;
Fig. 2 is the schematic diagram of sound-absorptive face mask;
Fig. 3 and Fig. 4 is the schematic diagram of acoustical panel;
Wherein, 1, sound-absorptive face mask, 2, acoustical panel, 3, wind cabinet, 4, upper sealing plate, 5, lower shrouding, 21, plate body, 22, silencing cotton layer, 23, sheet-metal layers, 24, aperture.
Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
As shown in Figures 1 to 4, a kind of lampblack absorber with sound-absorptive face mask, comprises wind cabinet 3, and the front end face of wind cabinet 3 is provided with access hole, and clean mouth is provided with sound-absorptive face mask 1.
Sound-absorptive face mask 1 comprises mask body, and mask body takes the shape of the letter U structure, is provided with acoustical panel 2 between mask body two parallel sides.
Acoustical panel 2 comprises plate body 21, and plate body 21 includes the sheet-metal layers 23 and silencing cotton layer 22 that are bonded as one, and the thickness of sheet-metal layers 23 is 1-3 times of silencing cotton layer 22 thickness, plate body 21 is densely covered with aperture 24, the interlaced arrangement of aperture 24.
The wind cabinet 3 of clean mouth upper end arranges upper sealing plate 4, the wind cabinet 3 of access hole lower end arranges lower shrouding 5.The sealing of sound-absorptive face mask 1 upper and lower side guaranteed by upper sealing plate 4 and lower shrouding 5.
The lower end of wind cabinet 3 connects air intake cover.The thickness of sheet-metal layers 23 is 2 times of silencing cotton layer 22 thickness.
Parallel between acoustical panel 2 and the base of mask body.The front end of mask body two parallel sides is provided with the profile of convex.
During work, the air-flow gone out from clean mouth directly strikes the silencing cotton layer 22 of acoustical panel 2, realizes noise reduction object, improves the anti-acoustic capability of lampblack absorber.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
