Abstract

A compressor and a method for assembling a compressor are provided. The compressor may include a compressor casing coupled to each of a suction inlet, into which a refrigerant may be introduced, and a discharge outlet, through which the refrigerant may be discharged, a compressor body mounted inside the compressor casing to compress the refrigerant suctioned in through the suction inlet, and then discharge the refrigerant through the discharge outlet, a noise reducing member disposed between the compressor body and the compressor casing, and at least one fixing member mounted inside the compressor casing to fix the noise reducing member to an inner wall of the compressor casing.

First claim

What is claimed is:

1. A compressor, comprising:
a compressor casing coupled to each of a suction inlet, into which a refrigerant is introduced, and a discharge outlet, through which the refrigerant is discharged;
a compressor body mounted inside the compressor casing to compress the refrigerant suctioned in through the suction inlet, and thereafter discharge the refrigerant through the discharge outlet;
a noise reducing member disposed between the compressor body and the compressor casing;
first and second fixing members mounted inside the compressor casing to fix both ends of the noise reducing member to an inner wall of the compressor casing, wherein the both ends of the noise reducing member are respectively inserted into the first and second fixing members; and
first and second plate springs, respectively, disposed at first and second lateral ends of the compressor body to allow the compressor body to be supported by the compressor casing, and wherein the first plate spring is mounted on the first fixing member, and the second plate spring is mounted on the second fixing member, wherein each of the first and second fixing members comprises:
a fixing portion fixed to the inner wall of the compressor casing, the fixing portion having a ring shape, and
a protrusion that extends from the fixing portion in a direction substantially perpendicular to a radial direction of the fixing portion.

2. The compressor according to claim 1 , wherein each of the first and second fixing members further comprises:
a plurality of spring mounts that extends in a radial direction of the respective fixing portion or the protrusion, wherein the plurality of spring mounts is spaced a predetermined distance from each other along a circumferential direction of the fixing portion or the protrusion.

3. The compressor according to claim 1 , wherein the compressor casing comprises:
a base shell having a cylindrical shape to accommodate the compressor body;
a first cover mounted at a first lateral end of the base shell, the first cover being coupled to the suction inlet; and
a second cover mounted at a second lateral end of the base shell, the second cover being coupled to the discharge outlet, wherein the noise reducing member is mounted on an inner wall of the base shell.

4. The compressor according to claim 3 , wherein the noise reducing member surrounds the inner wall of the base shell.

5. The compressor according to claim 4 , wherein the noise reducing member has a cylindrical shape, which is rolled at least three times.

6. The compressor according to claim 4 , wherein the noise reducing member comprises a plurality of cylindrical portions, which overlap each other, each of which has a slit in a side surface thereof.

7. The compressor according to claim 3 , wherein the first fixing member is fixed to the base shell, wherein the first lateral end of the noise reducing member is inserted into the first fixing member, wherein the second fixing member is fixed to the base shell, and wherein the second lateral end of the noise reducing member is inserted in to the second fixing member.

8. The compressor according to claim 7 , wherein each of the first and second fixing members is fixed to the base shell by a press-fit or welding.

9. The compressor according to claim 3 , wherein each of the first and second covers is coupled to the base shell by welding.

10. The compressor according to claim 1 , wherein the compressor body comprises:
a cylinder mounted along an axial direction of the compressor casing;
a piston accommodated within the cylinder, the piston being reciprocated along the as direction of the compressor casing; and
a motor that provides a drive force to reciprocate the piston.
