Abstract
The utility model relates to a silencer for a window-type air conditioner. The utility model comprises a rectification net fixed to an impeller body and rubber or spongy mass on the outer wall of an air outlet channel of a centrifugal fan. The utility model is characterized in that the silencer for a window-type air conditioner also comprises a volute sound absorbing body of a volute upper cover and one angular streamlined flow guiding sound absorbing body in the air outlet channel. The volute sound absorbing body and the flow guiding sound absorbing body are a perforated plate with a plurality of pores and an impedance composite sound absorbing and noise reducing absorption structure body composed of sound-absorbing materials contained in the sound absorbing and noise reducing absorption structure body. The utility model is characterized in that the noises of the air conditioner, particularly noises on an indoor side can be greatly decreased. The utility model has the advantages of simple structure, convenient installation, and low cost.
Description
The utility model relates to a kind of air-conditioner denoising device, particularly a kind of window air conditioner denoising device.
Window air conditioner is a kind of integral air conditioner equipment, have the refrigeration height, cold-producing medium is not revealed, and is cheap, advantage such as easy to install, its disadvantage is that noise is higher, and especially indoor centrifuge noise is bigger, therefore, reducing noise becomes the key factor of its complete machine performance, prior art is provided with the sound absorption damping material on Fan pipeline, or utilizes and to be fixed on the drum shape commutation net cover of being close to the centrifugal impeller air inlet on the impeller body, but noise reduction is not obvious.
The purpose of this utility model is to provide a kind of can effectively reduce window air conditioner, the particularly device of its indoor noise.
The utility model is near the spiral case loam cake bottom of window air conditioner centrifugal blower is provided with a spiral case (upper casing) sound absorber and the upper right turning in this blower fan exhaust passage near centrifugal impeller one side the streamlined water conservancy diversion sound absorber of a horn shape to be set, two sound absorbers can all be made of perforated plate and sound-absorbing material, and this sound absorber is a kind of good impedance complex sqouynd absorption lowering noise absorbent.
Advantage of the present utility model is not change under the situation of air-conditioner original structure pattern, reduces noise from air conditioner significantly, and the noise of air conditioner chamber's inner evaluation point is effectively controlled, and this apparatus structure is simple, easy to install, cost is low, is easy to promote.
Provide specific embodiment of the utility model in detail below in conjunction with accompanying drawing.
Fig. 1 structure of the present utility model and position view.
The structural representation of Fig. 2 water conservancy diversion sound absorber.
Fig. 3 perforated plate structural representation.
As Fig. 1, Fig. 2, the utility model comprises and is fixed on the commutation net cover 9 of being close to the centrifugal impeller air inlet on the impeller body and rubber or the cavernous body 2 on 8 outer walls of centrifugal blower exhaust passage, it is characterized in that it also is included in its corresponding spiral case sound absorber 4 of spiral case loam cake 3 bottoms of centrifugal blower near the setting of centrifugal impeller side, and near the upper right turning of blower fan exhaust passage 8, fix a streamlined water conservancy diversion sound absorber 5 of horn shape, spiral case sound absorber 4 and water conservancy diversion sound absorber 5, two sound absorbers all contain the impedance complex sqouynd absorption lowering noise absorbent that the sound-absorbing material in it constitutes by perforated plate 10 to be formed, and above-mentioned water conservancy diversion sound absorber 5 is fixed on snail tongue 6 one sides by support 7.
Above-mentioned have the perforated plate 10 of some apertures 11 to be made by metal or nonmetallic materials, should select aluminum alloy materials such as Fig. 3 usually.The optional organic or inorganic material fiber of sound-absorbing material in it, make the super glass wool plate of plate object as silk footpath at the super glass wool of 5-8 μ m etc., between perforated plate 10 and super glass wool 13, isolate usually or use the glass cloth package with thick cotton paper 12 liners of 1mm.The radial dimension of the aperture 11 on the perforated plate 10 is about 1.8mm, and the punching rate on the perforated plate is 15～18%, and the thickness of perforated plate is between 0.3～0.5mm.Obviously the denoising device of constructing thus can reduce the noise of the noise, particularly indoor of air-conditioner significantly.
