Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the noise-reducing structure of air-conditioner of the present invention and air-conditioner are further elaborated.Should be appreciated that specific embodiment described herein only for explaining the present invention, being not intended to limit the present invention.
Referring to figs. 1 through Fig. 7, air-conditioner one embodiment of the present invention 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, flows out housing 1 from noise-reducing structure 2.
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 two or more, and two or more acoustical panel 21 is horizontally set all, 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 up of metal material, and acoustical panel 21 is sheet metal component preferably.By the class waveform acoustical panel 21 of horizontally set, flow area is divided into multiple little region, allows in the passage 26 of noise between acoustical panel 21 and carry out multiple reflections, stop the direct projection of noise to spread out of by acoustical panel 21, reach the object reducing noise.
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 the longitudinal section length of respectively rolling over its both sides.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., 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.In the middle part of acoustical panel 21, the longitudinal section length of a folding is greater than the longitudinal section length of respectively rolling over its both sides, adds 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 is fixed, and plays guide effect to the air-flow that passage 26 passes in and out.
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, be adjacent two acoustical panels 21 partly overlapping regions in the horizontal direction between dotted portion in figure, namely the air outlet level by noise-reducing structure outside air-conditioner looks in, other part outside this noise-reducing structure of removing itself inside air-conditioner unit can not be seen, two adjacent acoustical panels 21 are partly overlapping in the horizontal direction, noise can not direct projection and going out in passage 26, can only spread out of, make noise attentuation after repeatedly refraction from passage 26.
Acoustical panel 21 is provided with quieter material 24, quieter material 24 is sponge, Sound-proof material or other there is the material of sound-absorbing effect, preferably, housing 1 inwall is provided with quieter material 24.When air-flow flows through this noise-reducing structure, the noise of quieter material meeting 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 symmetrical centre relatively in the middle part of it is symmetrical.Preferably, two adjacent acoustical panels 21 be arranged in parallel.
Adopt the acoustical panel 21 of multiple horizontally set that flow area is divided into multiple little region, and acoustical panel 21 is made class waveform, improve and wind flow field, stop noise directly to spread out of.Flow area is divided into multiple passage 26 by transversely arranged acoustical panel, 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 installed additional before and after noise-reducing structure 2 is as shown in the table:
As can be seen from the above table, after installing 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 multiple little region, improve and wind flow field, stop noise directly to spread out of, acoustical panel and housing arrange quieter material, make to carry out multiple reflections in the air-out passage of noise between quieter material, absorb pneumatic noise by quieter material, and stop the direct projection of noise to spread out of, reach the object reducing noise.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
