The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the noise-reducing structure of air-conditioner of the present utility model and air-conditioner are further elaborated.Should be appreciated that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
Referring to figs. 1 through Fig. 7, air-conditioner one embodiment of the present utility model comprises housing 1, fan assembly 4, heat exchanger 3 and noise-reducing structure 2, housing 1 is for holding fan assembly 4, heat exchanger 3 and noise-reducing structure 2, noise-reducing structure 2 is arranged on the air outlet place of air-conditioner, in Fig. 1, the direction of arrow represents the flow direction of air-flow, air-flow enters housing 1 from fan assembly 4, from noise-reducing structure 2, flows out housing 1.
Noise-reducing structure 2 comprises acoustical panel 21, and acoustical panel 21 is multi-fold structure, makes the longitudinal section of acoustical panel 21 be class waveform; The quantity of acoustical panel 21 is more than two, two above equal horizontally sets of acoustical panel 21, and two adjacent acoustical panels 21 are setting up and down, make to form passage 26 between two adjacent acoustical panels 21.Preferably, acoustical panel 21 is made by metal material, the preferred sheet metal component of acoustical panel 21.Class waveform acoustical panel 21 by horizontally set, is divided into a plurality of little regions by flow area, allows in the passage 26 of noise between acoustical panel 21 and carries out multiple reflections, by acoustical panel 21, stops the direct projection of noises to spread out of, and reaches and falls low noise object.
More preferably, as a kind of embodiment, the acoustical panel 21 of multi-fold structure, wherein the longitudinal section length of middle part one folding is greater than Ge Zhe longitudinal section, its both sides length.Preferably, the outermost folding in acoustical panel 21 one end and the outermost folding of the other end are all horizontally disposed with.In Fig. 5 and Fig. 6, acoustical panel 21 is 5 foldings, and wherein middle part one folding just becomes a middle folding, and certainly, the broken number of acoustical panel 21 also can be even number.The longitudinal section length of acoustical panel 21 middle part one foldings is greater than Ge Zhe longitudinal section, its both sides length, has increased the refraction number of times of noise in passage 26, reduces noise; The outermost folding in acoustical panel 21 one end and the outermost folding of the other end are all horizontally disposed with, and convenient installation fixed, and the air-flow of passage 26 turnover is played to guide effect.
More preferably, as a kind of embodiment, two adjacent acoustical panels 21 are partly overlapping in the horizontal direction, and the sight line in horizontal direction is blocked in passage 26.As shown in Figure 6, between dotted portion in figure, be adjacent two acoustical panels 21 overlapping regions partly in the horizontal direction, from air-conditioner outside, the air outlet level by noise-reducing structure looks in, can not see other part outside this noise-reducing structure itself of removing of air-conditioner unit the inside, two adjacent acoustical panels 21 are partly overlapping in the horizontal direction, noise can not direct projection in passage 26 and go out, and can only, through repeatedly spreading out of after refraction, make noise attentuation from passage 26.
On acoustical panel 21, be provided with quieter material 24, quieter material 24 has the material of sound-absorbing effect for sponge, Sound-proof material or other, and preferably, housing 1 inwall is provided with quieter material 24.When air flow stream is crossed this noise-reducing structure, quieter material is understood the noise of cancellation part air-flow, reaches the object of noise reduction.
More preferably, noise-reducing structure 2 also comprises end plate, and the quantity of described end plate is two, is respectively the first end plate 22 and the second end plate 23, and one end correspondence of acoustical panel 21 is arranged on the first end plate 22, and the other end is arranged on the second end plate 23.Acoustical panel 21 is fixed on described end plate by screw 25, easy disassembly.
More preferably, as a kind of embodiment, the longitudinal section of acoustical panel 21 is symmetrical structure, and the cross section of acoustical panel 21 is the symmetrical centre symmetry at its middle part relatively.Preferably, two adjacent acoustical panels 21 be arranged in parallel.
Adopt the acoustical panel 21 of a plurality of horizontally sets that flow area is divided into a plurality of little regions, and acoustical panel 21 is made to class waveform, improve and wind flow field, stop noise directly to spread out of.Transversely arranged acoustical panel is divided into a plurality of passages 26 by flow area, noise is when by passage 26, and partial noise is inner through multiple reflections at air-conditioner unit, cannot spread out of at all, the part that can spread out of is after the repeatedly refraction and reflection of passage 26, and noise figure also can reduce greatly.
The comparative test result that installs noise-reducing structure 2 front and back additional is as shown in the table:
As can be seen from the above table, install after noise-reducing structure 2, under equal air quantity, the noise of air-conditioner unit can reduce noise 5-7dB (A), and noise reduction is obvious.
The noise-reducing structure of the air-conditioner of above embodiment and air-conditioner, by the class waveform acoustical panel of horizontally set, flow area is divided into a plurality of little regions, improve and wind flow field, stop noise directly to spread out of, on acoustical panel and housing, quieter material is set, make to carry out multiple reflections in the air-out passage of noise between quieter material, by quieter material, absorb pneumatic noise, and stop the direct projection of noise to spread out of, reach and fall low noise object.
The above embodiment has only expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
