Silencer for scroll compressor

Abstract

The invention discloses a muffler for scroll compressor, which comprises a first muffler and a second muffler, wherein the first muffler has a pair of chambers and a gas passage hole, the chamber is defined above the outlet port of a fixed scroll and communicated with the outlet port, the gas passed hole is formed at the center of the upper end of the first muffler; and the second muffler is circumferentially equipped around the first muffler and separated with the gas passage hole on the first muffler, and the second muffler has a chamber communicated with one or more leading passages of the fixed scroll. The muffler can reduce work noise and completely separate oil contained in the exhaust gas, and can effectively separate the exhaust pressure inside the muffler from the outside suction pressure.

Description

technical field [0001] The present invention relates to a muffler for a scroll compressor, and more particularly, to a muffler for a scroll compressor that can reduce operating noise; sufficiently separate oil contained in exhaust gas; and can effectively isolate the muffler Internal discharge pressure and external suction pressure. Background technique [0002] As shown in Figure 1, a general scroll compressor includes: a main frame 2 and a sub-frame 3 installed in the housing at the upper position and the lower position of the housing 1; A stator 4 press-fitted in the housing 1 therebetween, and a rotor 5 disposed in the stator 4 and adapted to rotate by a force applied thereto. [0003] A vertical crankshaft 6 is fixedly inserted into the center of the rotor 5 such that opposite ends of the crankshaft 6 are rotatably supported by the main frame 2 and the subframe 3, respectively. In this way, the vertical crankshaft 6 rotates together with the rotor 5 . [0004] The sc...

Problems solved by technology

[0014] However, the above-mentioned conventional mufflers for scroll compressors have a simple shroud structure that defines only a single shielding wall, and thus cannot obtain sufficient noise transmission loss (TL).

In addition, conventional mufflers do not have the function of sufficiently separating oil contained in high-pressure refrigerant gas discharged through the outlet of the fixed scroll

Moreover, traditional mufflers cannot accurately isolate the exhaust pressure inside the muffler from the suction pressure outside

Due to these problems, it has been proven that the conventional mufflers described above lead to reduced performance and reliability of scroll compressors
