Below with reference to the muffler 100 of Fig. 1-Fig. 3 description a kind of compressor according to embodiments of the present invention, this muffler 100
Being assemblied on the supplementary bearing 5 of compressor 200, wherein this compressor 200 can be single cylinder rotary compressor, twin-tub rotation
Rotary compressor etc., are especially adapted for use in the compressor having steam vent on supplementary bearing 5.
The muffler 100 of compressor according to embodiments of the present invention, as shown in Figure 1-Figure 3, including: shell body 1 and interior
Housing 2, wherein, has cavity 13, and the top of cavity 13 is opened wide in shell body 1.Inner housing 2 is located at cavity 13
In, and between inner housing 2 and shell body 1, limit sound insulation chamber 3.This muffler 100 is assembled to compressor 200
Supplementary bearing 5 on time, shell body 1 is connected with supplementary bearing 5 to close cavity 13, specifically, can by screw will outward
Housing 1 is fixed on supplementary bearing 5.
In the communication process of sound wave, when sound wave is through inner housing 2, now due to the gas in cavity 13 and sound insulation
Gas blanket in chamber 3 and the difference of inner housing 2 characteristic impedance, cause two secondary reflections of sound wave, form decay, simultaneously
Again due to elasticity and the effect of absorption of the gas blanket in sound insulation chamber 3 so that the energy attenuation of acoustic vibration is relatively big,
When rear sound wave passes to shell body 1, there are again two secondary reflections of sound wave so that the sound wave through muffler 100 subtracts again
Few, in other words, the existence of the gas blanket in sound insulation chamber 3 can increase the order of reflection in propagation process of sound wave, and gas
Layer can produce additional absorption effect to sound wave, and the soundproof effect of the muffler 100 in the most this band sound insulation chamber 3 is better than thickness
Degree is shell body 1 and the soundproof effect of the muffler of inner housing 2 thickness sum.
The muffler 100 of compressor according to embodiments of the present invention, by being provided with inner casing in the cavity 13 of shell body 1
Limit sound insulation chamber 3 between body 2, and inner housing 2 and shell body 1, thus the gas blanket in sound insulation chamber 3 can increase sound
Ripple order of reflection in communication process, the gas blanket in sound insulation chamber 3 can produce additional absorption effect to sound wave simultaneously,
The soundproof effect making this muffler 100 is good, enhances the soundproof effect of muffler 100.
In further embodiment of the present invention, as in figure 2 it is shown, muffler 100 also includes sound-absorbing material 4, absorb sound material
Material 4 is filled in sound insulation chamber 3.Now, the sound-absorbing material 4 owing to being filled in sound insulation chamber 3 can as gas blanket
Increase sound wave order of reflection in communication process, and this sound-absorbing material 4 is better than gas to the additional absorption effect of sound wave
Layer, thus the soundproof effect of muffler 100 can be further enhanced.Wherein, this sound-absorbing material 4 can be mineral wool, ore deposit
Cotton, felt etc..It should be noted that different sound-absorbing materials is different at the acoustic absorptivity of each frequency range of noise, because of
This can be according to noise elimination demand, and the factor such as considering cost, assembly difficulty is chosen sound-absorbing material and determines sound-absorbing material
Loading.
Specifically, as it is shown in figure 1, shell body 1 includes: the body 10 of hollow and flange 11, wherein, body 10
Top open wide to limit cavity 13.Flange 11 stretches out from the outer peripheral edge at the top of body 10.Now noise reduction
When device 100 is assembled on supplementary bearing 5, the flange 11 of shell body 1 is connected with supplementary bearing 5, so that shell body 1
Simple in construction, and be easy to the assembling of shell body 1.Further, as shown in Figure 1-Figure 3, shell body 1 also includes
Flange 12, flange 12 upwardly extends from the free end of flange 11, when shell body 1 is assembled on supplementary bearing 5, turns over
Limit 12 is fastened on the periphery wall of supplementary bearing 5.Thus can be further ensured that between muffler 100 and supplementary bearing 5 close
Feng Xing.Preferably, this shell body 1 can be revolving body, the cross-sectional area of body 10 on direction from top to bottom gradually
Increase.
As depicted in figs. 1 and 2, in some embodiments of the invention, the diapire of inner housing 2 be formed through hole (figure not
Illustrate) it is suitable for being set on the supplementary bearing 5 of compressor 200, the outer of inner housing 2 is connected with shell body 1.This
Time, limit a sound insulation chamber 3 between inner housing 2 and shell body 1.So that the simple in construction of muffler 100.
Preferably, inner housing 2 is the revolving body of hollow, it is simple to the machine-shaping of inner housing 2.
As depicted in figs. 1 and 2, in some examples of the present invention, through hole is center through hole, the outer of inner housing 2 with
Flange 11 is connected.Now, inner housing 2 and shell body 1 can be independent machine-shaping part, and inner housing 2 is detachable
Be located on shell body 1, when being assembled on supplementary bearing 5 by muffler 100, first inner housing 2 can be set in countershaft
Hold on 5, then shell body 1 is assembled to the outer of the flange 11 and inner housing 2 making shell body 1 on supplementary bearing 5
Contact, is fixed on inner housing 2 and shell body 1 on supplementary bearing 5 finally by screw.Certainly the invention is not restricted to this,
The outer of inner housing 2 also can be connected to limit sound insulation chamber 3 with the sidewall of the body 10 of shell body 1.
In other embodiments of the present invention, inner housing 2 is multiple, and multiple inner housings 2 are respectively adapted to be set in compression
On the supplementary bearing 5 of machine 200, and multiple inner housing 2 is along the most spaced apart setting in direction from top to bottom, multiple inner casings
Body 2 limits between the inner housing 2 and shell body 1 of the bottom sound insulation chamber 3, two the most adjacent inner housings 2
Between limit sound deadening space.Now, sound wave propagate during, between two the most adjacent inner housings 2 every
Gas blanket in sound space can increase sound wave order of reflection in communication process, and the gas blanket in each sound deadening space
Sound wave produces the effect of additional absorption, and the gas blanket in sound insulation chamber 3 can increase anti-in communication process of sound wave simultaneously
Penetrate the gas blanket in number of times, and sound insulation chamber 3 and sound wave is produced the effect of additional absorption, thus can be further enhanced this and disappear
The soundproof effect of sound device 100.Further, can filling sucting sound material 4 in this sound deadening space.
As it is shown on figure 3, in the other embodiment of the present invention, inner housing 2 is multiple, each inner housing 2 is formed as
The arc shape being bent upwards is to limit sound insulation chamber 3 between shell body 1.The plurality of inner housing 2 is evenly distributed in
In cavity 13, now it is formed with multiple sound insulation chamber 3 in muffler 100, thus muffler 100 can be further enhanced
Soundproof effect.Certainly the invention is not restricted to this, this inner housing 2 may also be formed as reclinate arc shape, in other words,
Each inner housing 2 is formed as arbitrary shape, if make can to limit between each inner housing 2 and shell body 1 every
Sound chamber 3.
