Compressor having discharge mufflers

Abstract

Disclosed is a compressor having discharge mufflers for reducing the noise generated due to the discharge of a refrigerant. The compressor includes a compression chamber installed in a cylinder block in an airtight container; a discharge pipe installed in the airtight container for discharging a refrigerant compressed in the compressor to the outside of the airtight container; a first discharge muffler installed between the compression chamber and the discharge pipe, and provided with an inner space divided into a first space directly communicated with the compression chamber and a second space directly communicated with the discharge pipe; and a second discharge muffler provided with an inner space communicated with the first and second spaces respectively through separate communication channels.

1 . A compressor having discharge mufflers comprising: 
 a compression chamber installed in a cylinder block in an airtight container;    a discharge pipe installed in the airtight container for discharging a refrigerant compressed in the compressor to the outside of the airtight container;    a first discharge muffler installed between the compression chamber and the discharge pipe, and provided with an inner space divided into a first space directly communicated with the compression chamber and a second space directly communicated with the discharge pipe; and    a second discharge muffler provided with an inner space communicated with the first and second spaces respectively through separate communication channels.    
   
   
       2 . The compressor as set forth in  claim 1 , wherein the first and second mufflers are installed in the cylinder block, and the communication channels are formed in the cylinder block.  
   
   
       3 . The compressor as set forth in  claim 2 , wherein the communication channels are formed by drilling the cylinder block.  
   
   
       4 . The compressor as set forth in  claim 1 , wherein a partition member for dividing the inner space of the first discharge muffler into the first and second spaces is provided in the first discharge muffler, and the first and second spaces are divided by the partition member under the condition that the first and second spaces are isolated from each other and hermetically sealed.  
   
   
       5 . The compressor as set forth in  claim 1 , wherein a partition member for dividing the inner space of the first discharge muffler into the first and second spaces is provided in the first discharge muffler, and the first and second spaces are divided by the partition member under the condition that the first and second spaces are communicated with each other.  
   
   
       6 . The compressor as set forth in  claim 5 , wherein the first discharge muffler includes a depressed cavity formed in the cylinder block, a cover for closing the depressed cavity, and the partition member installed in the depressed cavity for dividing the inner space of the first discharge muffler into the first and second spaces, and a communication portion for communicating the first and second spaces is installed between the partition member and the cover.  
   
   
       7 . The compressor as set forth in  claim 1 , wherein the first discharge muffler includes a depressed cavity formed in the cylinder block, a cover for closing the depressed cavity, and a partition member installed in the depressed cavity for dividing the inner space of the first discharge muffler into the first and second spaces, and the partition member is integrally formed with the cylinder block by cast iron.
