Abstract

The invention discloses a muffler, which comprises a first part and a second part which are assembled together. The first part is an L-shaped plate body and an exhaust passage upward extends from the turning position of the L-shaped plate body. The second part is an L-shaped shell body and comprises a bottom wall and a side wall which upward extends around the bottom wall, the bottom wall and the side wall jointly form an internal cavity, an air inlet passage extends from the starting end of the L-shaped shell towards the direction of the turning position, the air inlet passage is communicated with the internal cavity, two approximately parallel guide plates extend from the side wall of the turning position of the L-shaped shell towards the direction of the inlet air passage, one opening of the guide plates is communicated with the air inlet passage, the other opening faces upward, and the position of the other opening is opposite to the position of exhaust passage of the first part. Since the muffler adopts a relative simple structure, the effective attenuation of noises is realized. Moreover, since the L shape fully utilizes the internal space of a compressor and the dimension of the muffler is effectively reduced, the exterior dimension of the entire compressor can be effectively reduced.

Baffler of the present invention has adopted simple relatively structure to realize the effective attenuation of noise, and its shape made full use of the inner space of compressor, has reduced self size effectively, thereby can effectively reduce the apparent size of compressor complete machine.

Other additional aspects of the present invention and advantage part in the following description provide, and part will become obviously from the following description, or recognize by practice of the present invention.

Description of drawings

The present invention is further detailed explanation below in conjunction with drawings and embodiments.

Fig. 1 is the decomposing schematic representation of the structure of baffler of the present invention.

Fig. 2 is the structural representation after the baffler of Fig. 1 is assembled together, shown in the figure in noise reduction process the flow direction of refrigerant air-flow.

Embodiment

Describe embodiments of the invention below in detail, described embodiment's example is shown in the drawings, and wherein identical from start to finish or similar label is represented identical or similar elements or the element with identical or similar functions.Below by the embodiment who describes referring to accompanying drawing is exemplary, only is used to explain the present invention, and can not be interpreted as limitation of the present invention.

Referring to Fig. 1, baffler 100 of the present invention comprises first portion 10 and second portion 20, and the two installs and fixes and forms described baffler 100 together.

Described first portion 10 is the L shaped plate body, and described L shaped plate body is by the installation that matches with described second portion 20 of its edge 16.

Described first portion 10 extends upward exhaust passage 12 in the turning point of L shaped plate body, described exhaust passage 12 in a tubular form, its end is a gas outlet 122.Described first portion 10 extends upward a fixed support plate 14 at the end of L shaped plate body, is used for playing when being installed in described baffler 100 in the compressor effect fixing and that support.

Described second portion 20 is L shaped housing, and its shape is corresponding with described first portion 10.Described second portion 20 comprises diapire 21 and around described diapire 21 upwardly extending sidewalls 23, described diapire 21 and sidewall 23 common formation have the described second portions 20 of internal cavities.

Installation matches with described first portion 10 at the edge 26 of described second portion 20 by its sidewall 23.Starting end at the L shaped housing of second portion 20 extends a gas-entered passageway 22 towards the turning point direction, described gas-entered passageway 22 in a tubular form, its starting end is gas access 222, and end extends to the turning point near described L shaped housing, and communicates with the internal cavities of second portion 20.The sidewall 23 of the turning point of the L shaped housing of second portion 20 extends the guide plate 24 of a pair of almost parallel towards described gas-entered passageway 22 directions.Opening of described guide plate 24 is terminal relative with described gas-entered passageway 22, another opening up, its position is relative with the position of the starting end of the exhaust passage 12 of described first portion 10.

Referring to Fig. 2, when mounted that the edge 16 of described first portion 10 is relative and superimposed with the edge 26 of the sidewall 23 of described second portion 20, just form described baffler 100 after interfixing.

When work, refrigerant air-flow direction of arrow in the figure enters the gas-entered passageway 22 of baffler 100 via gas access 222, enter the internal cavities of baffler 100 then from its end via described gas-entered passageway 22 guiding, enter described guide plate 24 by guide plate 24 towards the opening of described gas-entered passageway 22 ends then, discharge towards the opening of the exhaust passage 12 of described first portion 10 by described guide plate 24 sidewall 23 reflection backs through described second portion 20, the gas of discharging enters described exhaust passage 12 by the starting end of the exhaust passage 12 of described first portion 10, is discharged by the gas outlet 122 of described exhaust passage 12 ends to enter in the compressor compresses chamber again.

Enter the internal cavities of baffler 100 from described gas-entered passageway 22 at the refrigerant air-flow, enter after the reflection through 24 guiding of described guide plate and sidewall 23 in the process that described exhaust passage 12 discharges, the compound noise that the refrigerant air-flow causes, mobile noise that produces as the resonance of vibrating noise, valve, Aspirating valves and pulsations etc. have obtained decay effectively.

Baffler 100 of the present invention has adopted simple relatively structure to realize the effective attenuation of noise, and its shape made full use of the inner space of compressor, has reduced self size effectively, thereby can effectively reduce the apparent size of compressor complete machine.
