Technical field
The utility model relates to the noise elimination technique field, particularly a kind of noise elimination plenum chamber.
Background technology
Along with the development of society and the continuous progress of science and technology, the people's living standard is constantly improving, at present, occasions such as various music halls, gymnasium, Conference Hall, meeting room or theater are used seat widely, some seat has air-supply arrangement, can be used for blowing, thereby regulate the environment temperature around the seat, improve user's comfort level.But be directly to be blown by air supply duct mostly in the present air-supply arrangement, by the air outlet of under-seat wind sent, exist air-supply structure to produce certain noise in the existing this air-supply structure, influence user's comfort level.
The utility model content
The utility model proposes a kind of noise elimination plenum chamber, it can significantly reduce the noise that the under-seat air-supply arrangement produces, and improves user's comfort level.
The technical scheme that the utility model adopts specifically is achieved in that
The utility model provides a kind of noise elimination plenum chamber, it comprises air inlet, air outlet and is positioned at described air inlet and the sound-absorbing material layer of described air outlet inwall, described air inlet is positioned at the side of noise elimination plenum chamber, described air outlet is positioned at the top of noise elimination plenum chamber, and the position over against described air outlet has protuberance to described sound-absorbing material layer in the bottom that is positioned at the noise elimination plenum chamber.
Preferably, also comprise the flange that is positioned at described air outlet place.
Preferably, the length of described noise elimination plenum chamber is 300mm, and the diameter of described flange is 150mm.
Preferably, also comprise four jiaos of connecting elements that are positioned at four jiaos of places, described noise elimination plenum chamber top.
Preferably, described noise elimination plenum chamber is between floor insulation processing layer and floor.
Preferably, described sound-absorbing material layer comprises rotary glass cotton plate sound absorbing layer, glass fabric, perforation aluminium alloy plate and the galvanized sheet that sets gradually from inside to outside.
Noise elimination plenum chamber of the present utility model, it can significantly reduce the noise that the under-seat air-supply arrangement produces, and improves user's comfort level.

The specific embodiment
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent more, below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in detail, it will be more clear making above-mentioned and other purpose, feature and advantage of the present utility model.Reference numeral identical in whole accompanying drawings is indicated identical part.Painstakingly do not draw accompanying drawing in proportion, focus on illustrating purport of the present utility model.
Fig. 1 is the cross-sectional view of the noise elimination plenum chamber of the utility model specific embodiment.Fig. 2 is the vertical view of the noise elimination plenum chamber of the utility model specific embodiment.
In conjunction with illustrated in figures 1 and 2, the noise elimination plenum chamber 30 of the utility model specific embodiment comprises air inlet 31, air outlet 32 and is positioned at air inlet 31 and the sound-absorbing material layer 33 of air outlet 32 inwalls, air inlet 31 is positioned at the side of noise elimination plenum chamber, air outlet 32 is positioned at the top of noise elimination plenum chamber, and the position over against air outlet 32 has protuberance 331 to sound-absorbing material layer 33 in the bottom that is positioned at the noise elimination plenum chamber.Sound-absorbing material layer 33 coats the madial wall of whole air inlet 31 and whole air outlet 32, protuberance 331 arranges in the position over against air outlet 32, after wind is come in from the air inlet 31 of the side (for example from its four sides) that is positioned at the noise elimination plenum chamber, run into protuberance 331, under the drainage of its protuberance, can very successfully enter air outlet 32, the processing of eliminating the noise simultaneously.In the specific embodiment, the noise elimination plenum chamber is foursquare cube for the along continuous straight runs cross section, air inlet 31 is positioned at its four sides, the four sides air intake, protuberance 331 is the rectangular pyramid shape, play the effect of wind-guiding and noise elimination, make the wind of coming in from air inlet 31 enter air outlet 32 smoothly along the outer surface of rectangular pyramid and discharge.
In the noise elimination plenum chamber of the utility model specific embodiment, also comprise the flange 35 that is positioned at air outlet 32 places, in specific embodiment of the utility model, the length of noise elimination plenum chamber is 300mm, the diameter of flange 35 is 150mm, adopts flange can make air outlet 32 and its connecting portion seal better.Preferably, comprise that also 34, the four jiaos of connecting elements 34 of four jiaos of connecting elements that are positioned at four jiaos of places, noise elimination plenum chamber top can be so that the noise elimination plenum chamber be connected with miscellaneous part more easily.
The noise elimination plenum chamber of the utility model specific embodiment for example can be between floor insulation processing layer and floor.In the noise elimination plenum chamber of the utility model specific embodiment, preferably, sound-absorbing material layer 33 for example comprises that the rotary glass cotton plate sound absorbing layer, glass fabric, perforation aluminium alloy plate and the galvanized sheet that set gradually from inside to outside form jointly.
Noise elimination plenum chamber of the present utility model, it can significantly reduce the noise that the under-seat air-supply arrangement produces, and improves user's comfort level.
In above description, a lot of details have been set forth so that fully understand the utility model.But above description only is preferred embodiment of the present utility model, and the utility model can be implemented much to be different from alternate manner described here, so the utility model is not subjected to the restriction of top disclosed concrete enforcement.Any skilled personnel are not breaking away under the technical solutions of the utility model scope situation simultaneously, all can utilize method and the technology contents of above-mentioned announcement that technical solutions of the utility model are made many possible changes and modification, or be revised as the equivalent embodiment of equivalent variations.Every content that does not break away from technical solutions of the utility model according to any simple modification, equivalent variations and the modification that technical spirit of the present utility model is done above embodiment, all still belongs in the scope of technical solutions of the utility model protection.
