Suction muffler for compressor

Abstract

Disclosed is a suction muffler for a compressor, which effectively separates liquid components and oil components from a refrigerant, thereby reducing noise generated due to the suction of the refrigerant by the compressor and improving the performance of the compressor. The suction muffler includes a main body, to which a suction pipe of the compressor is connected; a refrigerant inflow chamber formed in the main body for allowing a refrigerant transmitted from the suction pipe to flow from the upper portion thereof to the lower portion thereof; a refrigerant outflow pipe for connecting a compression chamber of the compressor and the refrigerant inflow chamber; a resonance chamber formed in the main body such that the resonance chamber is divided from the refrigerant inflow chamber; a partition unit for dividing the resonance chamber and the refrigerant inflow chamber; and a communication portion formed through the partition unit for communicating the refrigerant inflow chamber and the resonance chamber.

1 . A suction muffler for a compressor comprising: 
 a main body, to which a suction pipe of the compressor is connected;    a refrigerant inflow chamber formed in the main body for allowing a refrigerant transmitted from the suction pipe to flow from the upper portion thereof to the lower portion thereof;    a refrigerant outflow pipe for connecting a compression chamber of the compressor and the refrigerant inflow chamber;    a resonance chamber formed in the main body such that the resonance chamber is divided from the refrigerant inflow chamber;    a partition unit for dividing the resonance chamber and the refrigerant inflow chamber; and    a communication portion formed through the partition unit for communicating the refrigerant inflow chamber and the resonance chamber.    
   
   
       2 . The suction muffler as set forth in  claim 1 , wherein the refrigerant inflow chamber includes a guide chamber for forming the lower portion of the refrigerant inflow chamber and guiding the refrigerant flowing to the lower portion of the refrigerant inflow chamber to the inside of the refrigerant outflow pipe, and the communication portion is formed through a portion of the partition unit above the guide chamber.  
   
   
       3 . The suction muffler as set forth in  claim 2 , wherein the partition unit includes an upper partition member extended downwardly from the inner surface of the upper portion of the main body and a lower partition member extended upwardly from the inner surface of the lower portion of the main body, and the communication portion is formed between the upper and lower partition members.  
   
   
       4 . The suction muffler as set forth in  claim 3 , wherein the upper partition member and the lower partition member are separated from each other under the condition that the upper and lower partition members cross each other, and the end of the lower partition member is located closer to the refrigerant inflow chamber than the end of the upper partition member.  
   
   
       5 . The suction muffler as set forth in  claim 3 , wherein a subsidiary communication portion for communicating the refrigerant inflow chamber and the resonance chamber is formed between the main body and a portion of the lower partition member close to the guide chamber.  
   
   
       6 . The suction muffler as set forth in  claim 5 , wherein the subsidiary communication portion is formed in the longitudinal direction of the lower partition member so that the subsidiary communication portion is communicated with the communication portion.  
   
   
       7 . The suction muffler as set forth in  claim 1 , wherein a first discharge hole for discharging liquid components and oil components contained in the refrigerant to the outside of the main body is formed through the main body at a portion in which the resonance chamber is formed.  
   
   
       8 . The suction muffler as set forth in  claim 7 , wherein a second discharge hole for discharging the liquid components and the oil components contained in the refrigerant to the outside of the main body is formed through the main body at a portion in which the guide chamber is formed.
