Muffler of closed type rolling rotor compressor

Abstract

The invention provides a compressor muffler with a partition plate, which includes an upper bearing of the compressor, a rotating shaft passing through its axis, and a muffler with an exhaust hole fixed above the upper bearing, wherein: the muffler It is set for a single layer with a partition plate, the partition plate is arranged on the inner part of the muffler, and a distance is set between the center hole of the partition plate and the rotating shaft. The effect of the present invention is that the muffler with the baffle extends the path of the air flow through the inner muffler, and the baffle is arranged along the distance between the central hole and the rotating shaft for exhausting, and the muffler is connected to the rotating shaft. The contact between them is tight, which improves the noise reduction effect. Moreover, the processing technology is simplified, and the material is saved.

Description

technical field [0001] The invention relates to a compressor, in particular to a muffler of a closed-type rolling rotor compressor which improves the structure of the muffler of the compressor. Background technique [0002] figure 1 It is a top view of an existing compressor muffler, and the muffler shown in the figure is used in a closed rolling rotor rotary compressor. The rotary compressor has a closed casing. The stator and rotor of the rotary compressor motor are installed on the upper part of the casing, and the eccentric shaft is fixed in the middle of the rotor. There is an eccentric part of the eccentric shaft in the cylinder bore, and there is a rolling rotor on the outer cylindrical surface of the eccentric part. When the eccentric part rotates in a circular motion with the eccentric shaft in the cylinder bore, the rolling rotor compresses the gaseous refrigerant entering the cylinder block. There is also a baffle plate (not shown) separating the refrigerant in ...

Problems solved by technology

[0006] When the compressor is working, the flow of gaseous refrigerant and the opening and closing of the exhaust valve will cause strong impact noise, and it has a wide frequency range, which is the main noise source of the compressor. The flow of gaseous refrigerant and the opening and closing of the exhaust valve Opening and closing will cause strong impact noise. The shape of the muffler is the same as the five-lobed structure, which is not only inconvenient to process and wastes materials, but also the inner space of the outer muffler is small, and the noise reduction effect is not good by expanding the volume. It is for noise in special frequency bands, and the noise reduction effect is even worse
