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.
With reference to Fig. 4, 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. 4, 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.
Referring to figs. 1 through Fig. 4, the noise-reducing structure 2 of air-conditioner of the present invention comprises acoustical panel 12, and acoustical panel 12 is multi-fold structure, makes the cross section of acoustical panel 12 be class waveform; The quantity of acoustical panel 12 is two or more, and two or more acoustical panel 12 is all longitudinally arranged, and two adjacent acoustical panels about 12 are arranged, and make to form air-supply passage between two adjacent acoustical panels 12.Preferably, acoustical panel 12 is made up of metal material, and acoustical panel 12 is sheet metal component preferably.By the class waveform acoustical panel 12 longitudinally arranged, flow area is divided into multiple little region, allows in the passage of noise between acoustical panel 12 and carry out multiple reflections, stop the direct projection of noise to spread out of by acoustical panel 12, reach the object reducing noise.
More preferably, as a kind of embodiment, the acoustical panel 12 of multi-fold structure, wherein the cross-section lengths of middle part one folding is greater than the cross-section lengths of respectively rolling over its both sides.Preferably, the outermost folding in acoustical panel 12 one end and the outermost folding of the other end are all horizontally disposed with.Acoustical panel 12 is 5 foldings, and wherein middle part one folding just becomes a middle folding, and certainly, the broken number of acoustical panel 12 also can be even number.In the middle part of acoustical panel 12, the cross-section lengths of a folding is greater than the cross-section lengths that its both sides are respectively rolled over, and adds the refraction number of times of noise in passage, reduces noise; The outermost folding in acoustical panel 12 one end and the outermost folding of the other end are all horizontally disposed with, and convenient installation is fixed, and play guide effect to the air-flow of passage turnover.
More preferably, as a kind of embodiment, two adjacent acoustical panel 12 in the vertical directions are partly overlapping, sight line on vertical direction is blocked in passage, namely the air outlet by noise elimination structure outside air-conditioner vertically looks in, other part outside this noise elimination structure of removing itself inside air-conditioner unit can not be seen, two adjacent acoustical panel 12 in the vertical directions are partly overlapping, noise in the channel can not direct projection and going out, can only spread out of from passage after repeatedly reflecting, make noise attentuation.
Acoustical panel 12 is provided with quieter material 13, quieter material 13 is sponge, Sound-proof material or other there is the material of sound-absorbing effect, preferably, housing 1 inwall is provided with quieter material 13.When air-flow flows through this noise elimination 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 locating support, and the quantity of described locating support is two, is respectively the first locating support 10 and the second locating support 11, one end correspondence of acoustical panel 12 is arranged on the first locating support 10, and the other end is arranged on the second locating support 11.Acoustical panel 12 is fixed by screws on described locating support, easy disassembly.
More preferably, as a kind of embodiment, the cross section of acoustical panel 12 is symmetrical structure.Preferably, two adjacent acoustical panels 12 be arranged in parallel.
Adopt multiple acoustical panel 12 longitudinally arranged that flow area is divided into multiple little region, and acoustical panel 12 is made class waveform, improve and wind flow field, stop noise directly to spread out of.Flow area is divided into multiple passage by the acoustical panel of longitudinal arrangement, noise is when by passage, 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, and noise figure also can reduce greatly.
The comparative test result installed additional before and after noise elimination structure is as shown in the table:
As can be seen from the above table, after installing noise elimination 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 longitudinally arranged, 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 deadener, 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.
