With, and the resistance of refrigerant gas flow can be reduced, and the noise of refrigerant gas can be reduced.
In some embodiments of the invention, as depicted in figs. 1 and 2, the entrance length of interpolation pipe is place silencing cavity
0.47-0.53 times of length, the outlet length of interpolation pipe are 0.22-0.28 times of the length of place silencing cavity.Wherein, interpolation pipe
It is threaded through on partition plate, the both ends of interpolation pipe are respectively facing the both sides extension of partition plate, an effluent of the air-flow by interpolation pipe from partition plate
To the opposite side of partition plate, the length positioned at the interpolation pipe of the side of the close interpolation tube inlet of partition plate is grown for the entrance of interpolation pipe
Degree, the length positioned at the interpolation pipe of the side of the outlet of the close interpolation pipe of partition plate are the outlet length of interpolation pipe.In addition, place
The length of silencing cavity is the length with the silencing cavity of the extending direction same general direction of interpolation pipe.Thus, it is possible to reduce noise reduction
The frequency that device 100 passes through, can play the role of refrigerant gas guiding, and can reduce the resistance of refrigerant gas flow
Power, and the noise of refrigerant gas can be reduced.
Further, as depicted in figs. 1 and 2, the entrance length of interpolation pipe is 0.5 times of length of place silencing cavity, interior
The outlet length of intubation is 0.25 times of the length of place silencing cavity.The theoretical analysis, it is possible thereby to make whole muffler 100 exist
In theory not over frequency, can further play the role of guiding to refrigerant gas, and can further subtract
The resistance of small refrigerant gas flow, and the noise of refrigerant gas can be reduced.
In some embodiments of the invention, as shown in Figure 4 and Figure 5, interpolation pipe is integrated into corresponding partition plate
Shape part.Thus, it is possible to simplify the assembly process between interpolation pipe and partition plate, at the same also eliminate between interpolation pipe and partition plate into
The process of row sealing, is conducive to save the production cycle, reduces production cost.
In some embodiments of the invention, as shown in Figure 1, interpolation pipe is set with corresponding divider upright.Thus
The processing of interpolation pipe and partition plate is not only convenient for, is also convenient for the flowing of air-flow, reduces the flow resistance of air-flow, and refrigeration can be reduced
The noise of agent gas.

Into in the first silencing cavity 6, then by the first interpolation pipe 41 enter the second silencing cavity 7 in, then by the second interpolation pipe 51 into
Enter in the 3rd silencing cavity 8, finally by 111 exhaust silencer 100 of gas outlet.
Refrigerant gas enters the first silencing cavity 6, the silencing cavity of inlet tube 2 to the first 6 by air inlet 121 and inlet tube 2
It is interior since section becomes larger suddenly, the mutation of sectional area can cause the reflection of sound wave and have transmission to lose, and carry out noise elimination noise reduction；Then
Refrigerant enters the second silencing cavity 7 by the first interpolation pipe 41, and as a same reason, in the second silencing cavity 7, refrigerant is out of first
The exit of intubation 41 reexpands, and the reflection that can cause sound wave by the mutation of sectional area is dropped again to produce to transmit to lose
Make an uproar；Refrigerant reaches the 3rd silencing cavity 8, refrigerant second interpolation pipe 51 out of the 3rd silencing cavity 8 by the second interpolation pipe 51 again
Outlet reexpand, further reduce sound wave by frequency, reduce noise again, reach energy-saving and noise-reducing noise elimination purpose.

Compressor according to embodiments of the present invention, the silencing cavity of multiple closings will be divided into by partition plate in housing 1, adjacent
Two silencing cavities are connected by interpolation pipe, can play good guiding function to the flow direction of refrigerant in breathing process, can have
Effect ground reduces the generation being vortexed during refrigerant flowing, reduces the flow resistance and the pressure loss of refrigerant, effectively reduces pressure
Contracting machine noise, ensures the overall performance of compressor.Meanwhile interpolation pipe coordinates with silencing cavity and inlet tube 2 coordinates with silencing cavity
Gas stream can be made to be expanded when going out interpolation pipe, sound wave reflection can produce transmission loss, can be effective so as to fulfill noise elimination noise reduction
Compressor noise is reduced, achievees the purpose that energy-saving and noise-reducing silencing vibration-damping.In addition, this kind of muffler 100 is simple in structure, noise reduction effect
Fruit is good.
