Refrigeration compressor with exhaust silencer structure

Abstract

The invention discloses a refrigeration compressor with an exhaust silencer structure. The refrigeration compressor with the exhaust silencer structure comprises an upper shell, a lower shell and an air cylinder seat arranged in the lower shell. The exhaust silencer structure is arranged between the air cylinder seat and the top end of the upper shell and adaptively connected with the upper end of the air cylinder seat. The exhaust silencer structure comprises a upper silencing shell, a lower silencing shell and an inserting plate, wherein the inserting plate is connected with the upper portion of the lower silencing shell to form a first silencing cavity located in the lower silencing shell; the upper silencing shell is connected with upper portion of the inserting plate to form a second silencing cavity located in the upper silencing shell; a ventilation hole is formed in the inserting plate; the lower silencing shell is connected with an air inlet pipe; the upper silencing shell is connected with an air outlet pipe. According to the refrigeration compressor with the exhaust silencer structure, the internal space of the compressor is fully used, the exhaust silencer structure is arranged in the compressor, and an exhaust silencer has better exhausting and silencing effects on the compressor.

Description

technical field [0001] The invention relates to a compressor, in particular to a refrigeration compressor with an exhaust muffler structure. Background technique [0002] With the improvement of technical level of hermetic refrigeration compressors, the product structure tends to be large displacement and small volume. Under the premise that the exhaust volume of the compressor cylinder hole remains unchanged, one of the main problems caused by the reduction of the compressor volume is that the effective volume of the gas flow in the exhaust pipeline is greatly reduced, which affects the resistive exhaust muffler. The noise reduction effect makes it difficult to realize the miniaturization of the hermetic refrigeration compressor. [0003] Conventional fully enclosed refrigeration compressor exhaust mufflers mainly use the exhaust structure cast by the cylinder block to effectively control the exhaust pulsation. The problems caused by this structural form are large volume, ...

Problems solved by technology

Under the premise that the exhaust volume of the compressor cylinder hole remains unchanged, one of the main problems caused by the reduction of the compressor volume is that the effective volume of the gas flow in the exhaust pipeline is greatly reduced, which affects the resistive exhaust muffler. The noise reduction effect makes it difficult to realize the miniaturization of the hermetic refrigeration compressor

[0003] Conventional fully enclosed refrigeration compressor exhaust mufflers mainly use the exhaust structure cast by the cylinder block to effectively control the exhaust pulsation. The problems caused by this structural form are large volume, small effective volume of gas flow, and complicated process , poor economy

In addition, there are some conventional hermetic refrigeration compressor exhaust mufflers with ring-shaped muffler structure, which is better in manufacturability than cylinder block casting, but this structure does not make full use of the gap between the cylinder block and the shell inside the compressor. Effective space, noise reduction effect is affected by space limitations
