Linear Compressor and the Supporter for the Same

Abstract

The present invention relates to a linear compressor compressing a working fluid in the cylinder such as a refrigerant and etc with the reciprocating movement of the piston in the cylinder due to the reciprocating force of the linear motor, and provides a linear compressor and the supporter for the same that the change of the lateral resonance frequency due to the lateral stiffness of the piston spring is easy as having a stub or a narrow part on the supporter preventing the increase of the mass inertia moment compared with the distance between the centroid of the supporter and the center of the piston spring sat on the supporter arm of the supporter, and capable of reducing the entire size and the manufacturing costs as raising the lateral resonance frequency easily without extending the length of the supporter arm.

1 . A linear compressor comprising:
 a supporter base; and   at least one of supporter arms extended from the base, and on which an elastic member is seated;   wherein a stub is arranged on at least one of the outside or inside of the supporter arm.   
   
   
       2 . The linear compressor according to  claim 1 ,
 wherein the supporter arm having the stub includes a supporter arm connection unit extended to a side direction from the supporter base, and a supporter arm supporting unit extended to the other side direction from the supporter arm connection unit and on which the elastic member is seated.   
   
   
       3 . The linear compressor according to  claim 1 ,
 wherein the supporter arm having the stub includes a supporter arm connection unit extended to a side direction from the supporter base, and a supporter arm supporting unit extended to the other side direction from the supporter arm connection unit and on which the elastic member is seated; and the stub is arranged on the supporter arm supporting unit.   
   
   
       4 . The linear compressor according to  claim 1 ,
 wherein the supporter arm having the stub is composed at least a pair symmetried to each other about the supporter base.   
   
   
       5 . The linear compressor according to  claim 1 .
 wherein the width of the supporter arm having a stud is regular or at least a part gets narrower as further from the supporter base.   
   
   
       6 . The linear compressor according to  claim 1 .
 wherein the supporter arm is composed of a first supporter arm having the stub and a second supporter arm without the stub.   
   
   
       7 . The linear compressor according to  claim 1 ,
 wherein the stub is at least one groove formed on the outline of the supporter arm.   
   
   
       8 . The linear compressor according to  claim 1 ,
 wherein the stub is at least a slot formed in the supporter arm.   
   
   
       9 . The linear compressor according to  claim 1 ,
 wherein the stub is positioned between the part corresponded to the center of the elastic member seated on the supporter arm and the supporter base.   
   
   
       10 . The linear compressor according to  claim 1 ,
 wherein the stub is symmetried to each other about the line connecting the point corresponded to the center of the elastic member seated on the supporter arm and the center of the supporter base.   
   
   
       11 . The linear compressor according to  claim 1   wherein the stub is formed as plural symmetried to each other about the line connecting the point corresponded to the center of the elastic member sat on the supporter arm and the center of the supporter base.   
   
   
       12 . A supporter of a linear compressor comprising:
 a supporter base; and   at least one of supporter arms on which an elastic member is seated; and wherein the one of the supporter arm has a part narrower than the width of the part corresponded to the center of the elastic member seated on the supporter arm.   
   
   
       13 . A linear compressor comprising: a supporter according to any one of  claims 1  to  12 .
