Abstract
The utility model discloses an exhaust silencer for a rotary compressor. The exhaust silencer comprises a cylindrical or stepped resonant cavity body and at least one clapboard, wherein an exhaust vent is formed in the bottom of the resonant cavity body, and each clapboard is provided with at least three through holes at intervals and is arranged in the resonant cavity body and located on the side with the exhaust vent of the resonant cavity body. The exhaust silencer has a simple structure, is convenient to manufacture and install, can improve a silencing effect greatly, is capable of rectifying exhaust of the compressor, and can be used for reducing flow loss and improving the operation efficiency of the compressor.
Description
Technical field
The utility model relates to a kind of muffler for rotary compressor.
Background technique
General rotary compressor is provided with muffler, to reduce the exhaust sound of compressor, the design of compressor silencer is not only influential to reducing noise, and the compressor heat mechanical property is also had very important impact, is related to the operational efficiency of compressor.Compressor silencer mainly utilizes Helmholtz resonant cavity principle to carry out noise reduction at present, and general baffler comprises the resonant cavity body, and the resonant cavity body can be straight tube shape, also can be stepped shaft, has exhaust port in resonant cavity body bottom.Because the baffler shape is compressed the restriction of machine interior space dimension, its erasure effect often can not reach perfect condition.Along with people are more and more higher to air conditioning comfortableness and quiet requirement, thereby the erasure effect of compressor air-discharging baffler is had higher requirement.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of muffler for rotary compressor, this muffler is simple in structure, fabrication and installation are convenient, significantly improve erasure effect, and can play the rectified action of compressor air-discharging, reduce flow losses, improve the operational efficiency of compressor.
For solving the problems of the technologies described above, the muffler that the utility model is used for rotary compressor comprises the resonant cavity body, described resonant cavity body is that straight tube shape or stepped shaft also have exhaust port in the bottom, this muffler also comprises at least one dividing plate, the interval has at least three through holes on the described dividing plate, and described dividing plate is located in the described resonant cavity body and is positioned at described exhaust port side.
Further, this muffler comprises two dividing plates, and described two dividing plates are located at respectively exhaust port side and the end difference of described stepped shaft resonant cavity body.
Further, aforementioned barriers is corrugated sheet or arc plate.
Further, the through-hole aperture on the aforementioned barriers is less than 3mm.
Further, the through hole on the aforementioned barriers is circle, ellipse or triangle.
Further, but the aforementioned barriers level, tilt or be vertical in the described resonant cavity body.
Because being used for the muffler of rotary compressor, the utility model adopted technique scheme, be that this muffler comprises the resonant cavity body, the resonant cavity body is that straight tube shape or stepped shaft also have exhaust port in the bottom, this muffler also comprises at least one dividing plate, the interval has at least three through holes on the dividing plate, and dividing plate is located in the resonant cavity body and is positioned at the exhaust port side of resonant cavity body.This muffler is simple in structure, and fabrication and installation are convenient, significantly improves erasure effect, and can play the rectified action of compressor air-discharging, reduces flow losses, improves the operational efficiency of compressor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of straight tube shape muffler;
Fig. 2 is the plan view of Fig. 1;
Fig. 3 is the structural representation of stepped shaft muffler;
Fig. 4 is the plan view of Fig. 3.
Embodiment
As depicted in figs. 1 and 2, the muffler that the utility model is used for rotary compressor comprises resonant cavity body 1, described resonant cavity body 1 is that straight tube shape or stepped shaft also have exhaust port 11 in the bottom, this muffler also comprises at least one dividing plate 2, the interval has at least three through holes 21 on the described dividing plate 2, and described dividing plate 2 is located in the described resonant cavity body 1 and is positioned at described exhaust port 11 sides.
Further, as shown in Figure 3 and Figure 4, this muffler comprises two dividing plates 2, and described two dividing plates 2 are located at respectively exhaust port 11 sides and the end difference 12 of described stepped shaft resonant cavity body 1.
Further, aforementioned barriers 2 can adopt corrugated sheet or arc plate.
Further, through hole 21 apertures on the aforementioned barriers 2 are less than 3mm.
Further, the through hole 21 on the aforementioned barriers 2 can be circle, ellipse or triangle.
Further, but aforementioned barriers 2 levels, tilt or be vertical in the described resonant cavity body 1.
This baffler arranges the aperture dividing plate in the resonant cavity body, so that the compressor section exhaust is discharged through aperture to the resonant cavity body bottom through-hole of dividing plate, utilize the principle of aperture noise reduction, effectively play the effect that reduces compressor noise, the dividing plate aperture also has the effect of rectification simultaneously, can make exhaust more even, thereby reduce flow losses, improve the operational efficiency of compressor.The aperture dividing plate can have various ways in this baffler, such as corrugated sheet or arc plate etc., the through hole of offering on it is not limited to circular hole, also can be the suitable elliptical aperture of area or tri-angle-holed etc., the aperture number is at least three on the dividing plate simultaneously, can be for being arranged in a plurality of apertures on the dividing plate; Dividing plate can be level, tilts or be vertical in the resonant cavity body and be positioned at the through hole of resonant cavity body bottom, when the resonant cavity body is hierarchic structure, can adopt two dividing plates to be located at respectively resonant cavity body bottom through-hole place and end difference.This muffler structure is simple, and fabrication and installation are convenient, and noise reduction is obvious, satisfies people to air conditioning comfortableness and quietly requirement.
