It is the one embodiment for the sound insulation compressor room that the utility model is proposed refering to Fig. 1-Fig. 7, a kind of sound insulation compression
Cabin, including bottom plate 2, back shroud 3, front shroud 4, upper plate 5, left side plate 6 and 7, and mutually assembling is fixed, and surrounds receiving compressor
1 cavity, compressor 1 are fixed on a base plate 2, and rear sound arrester 31 is provided with the outside of back shroud 3.By in back shroud 3
Outside is provided with rear sound arrester 31 so that rear sound arrester 31 does not have to take the space in cavity, is advantageous to dissipating for compressor 1
Heat；And the increase of the distance between rear sound arrester 31 and compressor 1, is advantageous to the decay of noise transmission, increases noise reduction；
And noise is outwards propagated and first had to by the noise reduction of back shroud 3, then rear sound arrester 31 is delivered to, is advantageous to further increase drop
The effect made an uproar；In addition, the assembling manufacturing of rear sound arrester 31 is simple, is advantageous to improve assembling speed, reduces cost.
It is shown in Figure 3 in the present embodiment, rear sound arrester 31 include being located at after-poppet 311 on back shroud 3 and
Rear sound absorbing layer 312 and rear puigging 313 on after-poppet 311, wherein, rear sound absorbing layer 312 and rear puigging 313 are from forward direction
After set, that is, after sound absorbing layer 312 be located at the front of rear puigging 313.Namely travel to making an uproar at rear sound arrester 31
Sound, first pass through rear sound absorbing layer 312 and absorb partial noise, then puigging 313 prevents the outside Spreading and diffusion of noise after reaching；This
Being provided with beneficial to the absorption and weakening for noise for two layers of sample, plays more preferable noise reduction.For rear sound absorbing layer 312 with after
The selection of the material of puigging 313, conventional sound-absorbing and acoustic material can be used.
Shown in Figure 4 in the present embodiment, after-poppet 311 has guide groove 3111 behind left and right be oppositely arranged two, rear to inhale
The left and right ends of sound-absorbing layer 312 and rear puigging 313 are located in rear guide groove 3111.After-poppet 311 also has the supporting plate of lower end
3112, the lower end of guide groove 3111 after the both ends of supporting plate 3112 connect two respectively, the lower end of rear sound absorbing layer 312 and rear puigging 313
In supporting plate 3112.Propped up after conveniently being so installed to rear sound absorbing layer 312 and rear puigging 313 from upper end
In frame 311.
In the present embodiment, by offering some sound-absorption holes 32 in the area defined of after-poppet 311 on back shroud 3, this
The noise sent in the course of work of sample compressor 1, a part can pass through the sound-absorption hole 32 that is opened up on back shroud 3, band segment
Noise absorbed by sound-absorption hole 32, play certain noise reduction；Sound arrester 31 after remaining noise reaches afterwards, first
Partial noise is absorbed by rear sound absorbing layer 312, then puigging 313 prevents the outside Spreading and diffusion of noise after reaching.Specifically quilt
The frequency range of absorption, the arrangement and sound-absorption hole 32 of the size opened up according to sound-absorption hole 32, multiple sound-absorption holes 32 on back shroud 3
It is relevant to locate the thickness of back shroud 3 etc. many factors.
Refrigerator when user family actually places, is placed by wall in most cases, new national standard noise test refrigerator
It is to be placed by wall；Therefore user is primarily for refrigerator front so that refrigerator front noise seems especially prominent.In the present embodiment,
It is shown in Figure 2, sound arrester 8 before being additionally provided with the front of compressor 1, preceding sound arrester 8 be located at front shroud 4 and compressor 1 it
Between.Noise of refrigerator test value is so not only effectively reduced, more can directly reduce refrigerator front surface region（The area of the frequent activity of user
Domain）Noise sense of hearing, lifted noise of refrigerator comfort level.
Shown in Figure 5 in the present embodiment, preceding sound arrester 8 includes vertically arranged fore-stock 81 and positioned at preceding branch
Preceding sound absorbing layer 82 and preceding puigging 83 on frame 81, preceding sound absorbing layer 82 and preceding puigging 83 are set from back to front；Namely noise
When traveling to forward up to preceding sound arrester 8, partial noise is absorbed by preceding sound absorbing layer 82 first, then reaches preceding puigging 83 and hinders
The only Spreading and diffusion of noise forward.Fore-stock 81 is fixed on a base plate 2, and the height of preceding sound arrester 8 is higher than compressor 1
Highly, the width of the left and right directions of preceding sound arrester 8 is more than the width of compressor 1.
Sound insulation compressor room in the present embodiment, refrigerator complete machine noise about 1 ~ 2dB can be effectively reduced, substantially in 2dB or so.
More current common scheme, sound insulating and absorbing positive effect, and low frequency noise in compressor 1 is had clear improvement.
It is shown in Figure 6, for the sound insulation compressor room and the experimental data of the acoustic absorptivity of existing scheme in the present embodiment
Contrast, as can be seen from the figure sound-absorbing effect of the invention is substantially better than the sound absorption of existing scheme, especially centering low frequency noise.
It is shown in Figure 7, for the sound insulation compressor room and the experimental data pair of the sound transmission loss of existing scheme in the present embodiment
Than as can be seen from the figure sound transmission loss of the invention is far superior to the sound transmission loss of existing scheme, and is that almost full frequency band is made an uproar
Sound soundproof effect is all good.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
