Embodiment 1

[0027] This embodiment provides a muffler assembly 10, such as figure 2 As shown, the muffler assembly 10 includes a muffler 1 and a cover plate 2, wherein the muffler 1 includes a raised portion 11 and a skirt 12 surrounding the raised portion 11 in the circumferential direction, and the cover plate 2 is fixed on the skirt 12 , and the first chamber 4 is formed between the above-mentioned cover plate 2, the raised portion 11 and the skirt 12, the raised portion 11 is provided with an opening-shaped chamber 3, and the raised portion 11 is provided with At least one exhaust hole 5 communicates with the chamber 3 and the first chamber 4 , and at least one exhaust port 6 communicated with the first chamber 4 is provided on the cover plate 2 . After the gas passes through the chamber 3, it will flow into the first chamber 4 through the exhaust hole 5, and then be discharged from the first chamber 4 through the exhaust port 6. Circulation, the baffle path of the gas has been incr...

Embodiment 2

[0037] This embodiment provides a compressor, which may be a rolling rotor compressor in this embodiment, such as Figure 6 As shown, the compressor includes the muffler assembly 10 described in Embodiment 1, and the upper flange 20 affixed to the muffler assembly, the muffler 1 of the above muffler assembly 10 and the upper flange 20 form a The second chamber 30, specifically the opening-shaped chamber 3 on the raised portion 11 and the upper flange 20 jointly form the second chamber 30, the second chamber 30 and the first chamber 4 pass through the exhaust hole 5 connected. The compressed gas produced by the compressor first enters the second chamber 30 , then flows into the first chamber 4 through the exhaust hole 5 , and then flows into the lower cavity of the motor through the exhaust port 6 on the cover plate 2 . Through the above-mentioned muffler assembly 10, the exhaust noise of the compressor can be effectively reduced, and the newly added first chamber 4 of the abo...

Abstract

The invention belongs to the related field of compressors, and discloses a silencer assembly and a compressor. The silencer assembly comprises a silencer and a cover plate, the silencer comprises a convex portion and a skirt edge which is circumferentially arranged on the convex portion in a surrounding mode, the convex portion is provided with an opening-shaped cavity, the cover plate is fixedly connected to the skirt edge, and the cover plate, the convex portion and the skirt edge form a first cavity; the convex portion is provided with at least one exhaust hole which communicates the cavity with the first cavity, and the cover plate is provided with at least one exhaust port communicated with the first cavity. The compressor comprises the silencer assembly. The silencer assembly has the advantage that the noise elimination and reduction effects can be effectively improved; the compressor with the silencer assembly has the advantages that the noise elimination and reduction effects can be improved while the motor position is not changed, and the adverse influence that the compressor generates excessive vibration cannot be caused.

Description

technical field [0001] The invention relates to the technical field related to compressors, in particular to a muffler assembly and a compressor. Background technique [0002] In the rolling rotor compressor, a muffler is provided to reduce the exhaust noise. figure 1 Schematic diagram of the existing muffler installed on the compressor, from figure 1 It can be seen from the figure that the existing upper muffler 100 is generally a single-chamber structure, which is fixed on the upper flange 110 for noise reduction. However, the noise reduction effect of the upper muffler 100 is limited. In order to improve its noise reduction effect, the volume of the upper muffler is usually increased at present, so that the height of the upper muffler needs to be increased. However, due to the limited space of the motor lower cavity , If the height of the muffler is increased, the motor needs to be moved up to increase the space, which will cause adverse effects such as excessive vibrat...
