Abstract

The present disclosure relates to a reciprocating compressor and a method for assembling the same. According to an embodiment of the present disclosure, a reciprocating compressor includes: a shell to which a discharge pipe is coupled; a driving unit mounted inside the shell to generate a rotary force; a compression unit having a connecting rod configured to convert the rotary force to a straight driving force, a piston connected to the connecting rod, and a cylinder into which the piston is movably inserted; a discharge hose from which a refrigerant compressed in the cylinder is discharged, and disposed to abut an inner circumferential surface of the shell; and a connection member configured to connect the discharge hose to the discharge pipe, wherein at least a portion of the connection member is inserted into an inner portion of the discharge pipe, and another portion thereof is supported outside the discharge pipe.

First claim

What is claimed is:

1. A reciprocating compressor, comprising:
a shell having an inner portion;
a discharge pipe coupled to the shell and formed of metallic material, the discharge pipe having an inner portion;
a driver located at the inner portion of the shell to generate a rotary force;
a compressor located in the shell, the compressor including:
a connecting rod configured to convert the rotary force to a linear driving force;
a piston connected to the connecting rod; and
a cylinder into which the piston is movably inserted;

a discharge hose through which a refrigerant compressed in the cylinder is discharged, the discharge hose being disposed adjacent an inner circumferential surface of the shell defining the inner portion; and
a connection member configured to connect the discharge hose to the discharge pipe, a first portion of the connection member being inserted into the inner portion of the discharge pipe and a second portion of the connection member being supported outside the discharge pipe, and the connection member having an insertion portion into which the discharge hose is inserted and including:
a first main connection body having a hollow cylindrical shape;
a second main connection body having a hollow cylindrical shape and extending from the first main connection body, the second main connection body being inserted into the inner portion of the discharge pipe and having an outer circumferential surface on which at least one groove is formed, wherein the insertion portion forms inner circumferential surfaces of the first and second main connection bodies; and
a locking step defined by a junction of the first main connection body and the second main connection body, wherein an end portion of the discharge pipe supports the locking step, wherein, with respect to the locking step, a diameter of the first main connection body is formed greater than that of the second main connection body,

wherein the reciprocating compressor further comprises at least one interference member installed in the at least one groove and arranged to come in close contact with an inner circumferential surface of the discharge pipe.

2. The reciprocating compressor according to claim 1 , wherein the at least one interference member includes a first interference member and a second interference member spaced apart from the first interference member on the outer circumferential surface of the second main connection body.

3. The reciprocating compressor according to claim 1 , further comprising a muffler assembly into which a refrigerant compressed in the cylinder is introduced, and from which the discharge hose extends toward the discharge pipe.

4. The reciprocating compressor according to claim 3 , further comprising a clamp to catch a portion of the discharge hose so as to space the discharge hose apart from the inner circumferential surface of the shell.

5. The reciprocating compressor according to claim 1 , wherein the at least one interference member has a ring shape.

6. The reciprocating compressor according to claim 1 , wherein the at least one groove is recessed from the outer circumferential surface to have a ring shape.

7. The reciprocating compressor according to claim 1 , wherein the at least one interference member is formed of a plastic or rubber.

8. The reciprocating compressor according to claim 1 , wherein the at least one interference member includes a first interference member and a second interference member, and
wherein the at least one groove comprises two grooves in which the first interference member and the second interference member are installed.
