Abstract
The utility model discloses a kind of noise elimination air-intaking box, and comprise the first air opening plate, the second air opening plate, side plate, top cover and rear plate, it is characterized in that: be provided with muffler plate in this case, described muffler plate one end is fixed on the side of the first air opening plate; In α angle between the described muffler plate other end and the first air opening plate; Described first air opening plate, the second air opening plate, side plate, top cover, rear plate and muffler plate uniform fold noise elimination cotton.This practicality has the effect of heat preserving sound deadening to whole air channel, reduce blower fan, air-intaking box condensation, simple and reliable for structure, highly versatile, be easy to connect, lift, inwall insulation is eliminated the noise, and avoids the loss that air and casing external energy exchange, save energy consumption, adopt easy labyrinth cell-type and damp type quieter manner can effectively reduce the noise 3-6 decibel of air return system.
Description
Technical field
The utility model relates to coil pipe of air-conditioner blower air return system field, particularly one noise elimination air-intaking box.
Background technology
Inlet air pipeline is directly communicated with wind pipe by the return air duct of prior art, does not arrange any silencing equipment, and when large-size air conditioning runs, noise ratio is comparatively large, although the pipeline of air-supply is longer, still finds that the noise of pipeline is somewhat large when actual motion.
Utility model content
The purpose of this utility model will overcome above-mentioned shortcoming exactly, aims to provide a kind of noise elimination air-intaking box.
For achieving the above object, noise elimination air-intaking box of the present utility model, comprise the first air opening plate, the second air opening plate, side plate, top cover and rear plate, be provided with muffler plate in this case, described muffler plate one end is fixed on the side of the first air opening plate; In α angle between the described muffler plate other end and the first air opening plate; Described first air opening plate, the second air opening plate, side plate, top cover, rear plate and muffler plate uniform fold noise elimination cotton.
Further, described α is 55 degree.
Further, the aperture position of described second air opening plate is corresponding with described muffler plate.
Further, the length and width of described muffler plate are consistent with the length and width of described first air opening plate and the second air opening plate.
Further, described noise elimination cotton undulate egg form.
Compared with prior art, the technical solution of the utility model has the following advantages: this practicality has the effect of heat preserving sound deadening to whole air channel, reduce blower fan, air-intaking box condensation, simple and reliable for structure, highly versatile, is easy to connect, lift, inwall insulation is eliminated the noise, avoid the loss that air and casing external energy exchange, save energy consumption, adopt easy labyrinth cell-type and damp type quieter manner can effectively reduce the noise 3-6 decibel of air return system.
Accompanying drawing explanation
Fig. 1 is the sectional view of the utility model noise elimination air-intaking box;
Fig. 2 is the noise transmission of the utility model noise elimination air-intaking box and the schematic diagram reduced;
Fig. 3 is the utility model noise elimination air-intaking box overall structure schematic diagram.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in figures 1 and 3, noise elimination air-intaking box of the present utility model, comprise the first air opening plate 1, second air opening plate 2, side plate 3, top cover 4 and rear plate 5, be provided with muffler plate 6 in this case, described muffler plate 6 one end is fixed on the side of the first air opening plate 1; In α angle between described muffler plate 6 other end and the first air opening plate 1; Described first air opening plate 1, second air opening plate 2, side plate 3, top cover 4, rear plate 5 and muffler plate 6 uniform fold noise elimination cotton 7.
The angle [alpha] of muffler plate 6 and the first air opening plate 1 is fixed as 55 degree, can ensure that return air inlet does not directly block minimizing resistance, if α is less than 55 degree, muffler plate 6 and rear plate 5, apart from too near, affect air-out efficiency; If α is greater than 55 degree, noise can be reflected back the second air opening plate 2, and noise can not be consumed in casing, can not play the effect of noise reduction.
The aperture position of the second air opening plate 2 is corresponding with described muffler plate 6, makes the noise very first time be transmitted on muffler plate 6, then rebounds to top cover 4, side plate 3 and rear plate 5, after repeatedly rebounding, effectively reduces noise.
The length and width of described muffler plate 6 are consistent with the length and width of the first air opening plate 1 and the second air opening plate 2.
Described noise elimination cotton 7 undulate egg form, the effect improving noise bounce-back and absorb.
Fig. 2 is the sonic propagation figure that makes an uproar, arrow represents the bounce-back of noise, noise front propagation path is blocked by muffler plate and is absorbed by noise elimination cotton, unnecessary noise reflection is absorbed by air-intaking box inwall noise elimination cotton again to air-intaking box internal face, for whole air return system noise reducing successful, at least reduce noise 3-6 decibel after tested, only the noise below air outlet is specified in country's fan coil standard, return air inlet blower motor place is only real vibroseis, only has the noise reducing this place, really could reduce the noise in room, this utility model invention design can realize this target.Design wave egg form noise elimination cotton energy, has insulation, a loss that characteristic that is energy-conservation, noise reduction avoids air and casing external energy to exchange, saves energy consumption, reduce blower fan in fan coil units, air-intaking box condensation, air-intaking box space is large, and wind speed is low, and resistance is little can realize energy-efficient target.
In sum, above-mentioned embodiment is not restricted embodiment of the present utility model, and the modification that all those skilled in the art carry out on the basis of flesh and blood of the present utility model or equivalent deformation, all at technology category of the present utility model.
