[0002] In rotary compressors, airflow noise is one of the main noise components of the compressor. It is generally caused by the jet noise emitted by the airflow through the exhaust hole of the muffler during the compressor exhaust process, and the jetted airflow directly facing the rotor, resulting in turbulent noise during the rotation of the rotor, which includes the effects of one or more frequency bands of noise, and it is difficult to eliminate the noise of multiple frequency bands directly.

[0005] Furthermore, the baffle structure includes: a vertical plate arranged close to the circumferential surface of the cylinder and a baffle arranged perpendicular to the vertical plate.

[0006] Preferably, the baffle structure is arranged around the circumference of the cylinder.

[0007] Furthermore, the muffler is provided with an exhaust port with the exhaust direction facing the position covered by the baffle structure.

[0008] Preferably, the exhaust ports are arranged in multiple arc-shaped lines along the positions covered by the baffle structure.

[0016] Compared with the prior art, the present invention uses a double-layer micro-perforated silencer to reduce noise in one or more frequency bands. The inner silencer uses the side exhaust method to more effectively use the silencer holes to reduce noise; the silencer is provided with a baffle structure to reduce the impact of the airflow on the rotor while reducing noise, and also avoids the gas being discharged directly from the exhaust hole near the inner silencer, reducing the impact of the gas discharged from the silencer on the rotor. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention is described in detail below with reference to the embodiments and accompanying drawings, wherein:

[0018] Figure 1 A side view of the silencer and the inner silencer separated in the embodiment of the present invention;

[0019] Figure 2 A top view of a muffler in an embodiment of the present invention;

[0020] Figure 3 It is a top view of the inner silencer in the embodiment of the present invention. DETAILED DESCRIPTION

[0021] like Figure 1 , Figure 2 As shown, the present invention proposes a compressor silencer structure, including a silencer 1, which is installed on the upper flange of the compressor and is provided with a through hole, which can be used to pass through a rotor or a column on which a rotor is installed, wherein a circle of baffle structure 11 is provided on the edge of the through hole, which can block the airflow impacting the rotor, reduce the impact of the airflow flowing out of the silencer 1 on the rotor, and avoid the turbulence noise caused by the airflow impacting the rotor.

[0022] In a specific embodiment, the baffle structure 11 includes: a vertical plate 111 and a baffle 112. The vertical plate 111 is arranged in an arc shape near the circumferential surface of the cylinder. The baffle 112 is perpendicular to the vertical plate and surrounds the cylinder to block the silencer hole above the silencer to reduce the impact of the airflow on the rotor.

[0023] In the present invention, the top surface of the muffler 1 arranged perpendicular to the rotor axis is provided with a plurality of silencer holes 12 and an exhaust port 13. The silencer holes 12 are arranged evenly at intervals, which can eliminate noise within a certain frequency and improve the noise reduction effect. Compared with the prior art method of only arranging a plurality of silencer holes in the inner layer, it is more convenient to process. The exhaust port 13 is arranged in two arcs along the position covered by the baffle structure, so that the airflow discharged from the exhaust port 13 faces the baffle of the baffle structure, thereby using the baffle structure to block the airflow from the exhaust port that impacts the rotor.

[0024] like Figure 3 As shown, the present invention also includes an inner silencer 2, which is arranged between the upper flange and the silencer 1, so that two silencer chambers are formed between the upper flange and the silencer 1. At the same time, the top surface of the inner silencer 2 arranged perpendicular to the rotor axis is provided with a plurality of second silencer holes 21 connecting the two silencer chambers. The second silencer holes 21 are evenly spaced and cooperate with the silencer holes 12 on the silencer 1 to form a double-layer silencer structure, which can eliminate noise of one or more frequencies and increase the silencer range and silencer effect. In addition, the side wall of the inner silencer 2 arranged parallel to the rotor axis is provided with an exhaust hole 22 to ensure the normal exhaust of the compressor and avoid affecting the silencer effect.

[0025] In a specific embodiment, the outer contour of the inner silencer 2 is the same as that of the silencer 1, and the volume is slightly smaller than that of the silencer 1, which is convenient for processing and manufacturing and reduces the processing difficulty. Among them, the specific outer shape of the inner silencer 2 is: the part perpendicular to the rotor axis is the top surface, and the top surface is provided with a through hole and a silencer hole, and the through hole is used to pass through the rotor or the cylinder, and the outer edge of the top surface is a circle of side walls perpendicular to the top surface, and the bottom of the side wall is bent to form a circle of mounting plates 23 that can be close to the upper flange, and the mounting plate 23 is provided with a plurality of mounting holes 24 evenly spaced, and the muffler 1 and the inner silencer 2 are fixed after being connected to the upper flange by screws passing through the mounting holes 24 of the muffler 1 and the inner silencer 2 at the same time.

[0026] The present invention also proposes a compressor using the above compressor silencer structure. The compressor uses a double-layer micro-perforated silencer to reduce noise in one or more frequency bands. Among them, the inner silencer uses side exhaust (the side exhaust hole is not necessary and can be opened in other parts, but in order to make full use of the silencer hole, it is better to design the exhaust hole to be opened on the side) to more effectively use the silencer hole for noise reduction; the silencer reduces the impact of the airflow on the rotor while reducing noise by setting a baffle structure, and also avoids the gas being discharged directly from the exhaust hole near the inner silencer, thereby reducing the impact of the gas discharged from the silencer on the rotor.

[0027] The present invention also provides an air conditioner using the compressor.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
