Specific embodiment
Below with reference to specific embodiment shown in the drawings, the present invention will be described in detail.But these implementation methods are simultaneously
The present invention is not limited, structure that one of ordinary skill in the art is made according to these implementation methods, method or functionally
Conversion is all contained in protection scope of the present invention.
In embodiments of the present invention, specific explaination is done to noise-reduce device for compressor of the invention by taking refrigerator as an example,
But it should explanation, involved skill spirit can alternatively be used other forms in embodiment disclosed below
On refrigeration plant, exemplarily, such as refrigerator.
With reference to Fig. 1, compressor 10 is fixed in the supporting plate 31 in press storehouse 30 by footing fixing device 20, and by matching somebody with somebody
Pipe 40 is in communication with the outside.Denoising device 50 is set in press storehouse 30, and the device 50 is the hollow cavity of bottom opening, compressor 10
It is contained in the inside cavity.Preferably, the inwall of denoising device 50 is at least 10mm with the distance of the housing of compressor 10, has both ensured pressure
Contracting machine does not form overhead speaker when working with the overlap joint of denoising device 50, and the occupancy to the volume of press storehouse 30 is reduced again.The quilt of denoising device 50
It is arranged such to cut down the noise of compressor, especially the noise of upper shell radiation.
Denoising device 50 hangs on the roof of press storehouse 30, and its bottom is hanging, is not contacted with press orlop portion or other structures.
In this way, the air inside and outside denoising device 50 can circulate through the opening of its bottom, radiated beneficial to compressor 10.
The top of denoising device 50 sets an at least connecting portion 51, for the suspension of denoising device 50 to be fixed on into press Cang30Ding
Wall.Connecting portion 51 opens up through hole 52, is used to wear fastener, such as screw or screw.Fastener passes through through hole 52 and press storehouse
30 roofs are connected.Vibration-damped component 60 is set between fastener and through hole 52.Preferably, vibration-damped component 60 is rubber mount.
In another implementation method of the present invention, denoising device 50 is also mountable in the bottom support plate 31 of press storehouse 30（Do not scheme
Show）.Wherein, connecting portion 51 is located at the bottom of denoising device 50, is connected with supporting plate 31 by fastener.The body of denoising device 50 is not
Contacted with supporting plate 31 or other press chamber structures, gap is formed between its bottom and press storehouse 30, so that in denoising device 50
Outer air can circulate through the opening of its bottom.
With reference to Fig. 2 and Fig. 3, in an embodiment of the present invention, the substantially cuboid of denoising device 50, including top surface and
Four sides.Denoising device 50 can also be spheroid or other can coat the structure of the housing of compressor 10.The work of compressor is made an uproar
Sound only directs out propagation in bottom, and the noise in other each faces penetrates denoising device 50 or reflexes to bottom through denoising device 50
Could outwards be propagated during portion, increased the path loss of noise transmission.
Specifically, with reference to Fig. 4, the cavity wall of denoising device 50 is individual layer thin-slab structure 53, such as aluminium sheet.The size of oise insulation factor
Depend primarily on the thin-slab structure in itself, because the noise magnitude that compressor 10 is produced is relatively small, the thickness range desirable 1 of sheet material
~5mm.Individual layer thin-slab structure 53 can be that rigidity on-deformable thin-slab structure higher, or rigidity are relatively low with bending
The flexible structure of deformability, the shape of sheet material can be planar structure, or bellows-shaped, or inwall is non-smooth
Surface.
With reference to Fig. 5, in order to further absorb vibration, one damping layer 54, noise can be set in the outer surface of thin-slab structure 53
The thin plate vibration for causing can be damped layer 54 and absorb, and reduce the energy of back wave.
Partial noise is outwards conducted through the reflection of each face of denoising device 50 from bottom, by increasing the transmission amount in each face, can
Lost with the transmission for increasing sound, so as to reduce this partial noise.With reference to Fig. 6, thin-slab structure 53 is the bilayer with a gap
Thin plate 531,532, spacing is q between two-layer thin plate 531,532.As q=2 ~ 5mm, the oise insulation factor of noise is significantly improved, especially
It is the high-frequency noises of more than 1000Hz.The through hole of array arrangement is set on the thin plate 531 by compressor, and percent opening is not with
It is advisable more than 15%.Through thin plate 531 is into the spatia 55 between two-layer 531,532 and reflects wherein, energy enters such sound wave
One step decays.
With reference to Fig. 7, can also increase by an absorbent treatment 56 between two-layer thin-slab structure 531,532.The layer 56 is using sound absorption
Material, depends on the inwall of thin plate 532.After the thin plate 531 of sound wave perforated enters into spatia 55, sound wave is in multiple reflections
At utmost absorbed by sound-absorbing material.
To avoid compressor 10 from being overheated when working, set in the inside of denoising device 50 or periphery and promote convection device, to improve
Heat dispersion.Some temperature sensing points are set in press storehouse, when temperature rises to preset value, are started and is promoted convection device to compression
Machine 10 radiates.
Specifically, with reference to Fig. 8, axial flow blower 71 is arranged in denoising device 50, is directly blown to compressor 10.Using straight
The blower fan that footpath is larger, working speed is relatively low, to reduce the noise that blower fan is produced in the course of the work.Blower fan work speed-frequency control
System should be within 200 ~ 300Hz.
With reference to Fig. 9, Figure 10, axial flow blower 71 can be substituted with centrifugal blower 72, cross flow fan 73.
Or, with reference to Figure 11, axial flow blower 71 is arranged at the side of denoising device 50, is blown to denoising device 50.
It should be understood that, although the present specification is described in terms of embodiments, but not each implementation method only includes one
Individual independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art will should say
Used as an entirety, technical scheme in each implementation method can also be through appropriately combined, and forming those skilled in the art can for bright book
With the other embodiment for understanding.
Those listed above is a series of to be described in detail only for feasibility implementation method of the invention specifically
Bright, they simultaneously are not used to limit the scope of the invention, all equivalent implementations made without departing from skill spirit of the present invention
Or change should be included within the scope of the present invention.
