Abstract

A compressor is disclosed. The compressor includes an upper shell and a lower shell forming an appearance of the compressor. The compressor also includes a coupling portion provided between the upper shell and the lower shell and configured to protrude from a side surface of the upper shell or the lower shell to outside the upper shell or the lower shell. The coupling portion includes at least one coupling protrusion configured to protrude from a side surface of a flange portion to the outside, to increase a rigidity of the flange portion and the coupling portion.

First claim

What is claimed is:

1. A compressor comprising:
an upper shell and a lower shell forming an exterior of the compressor; and
a coupling portion provided between the upper shell and the lower shell and configured to:
protrude from a side surface of the upper shell to an outside of the lower shell, or a side surface of the lower shell to an outside the upper shell,

wherein the coupling portion comprises:
a flange portion protruding on the outside of the lower shell or the outside of the upper shell, and
at least one coupling protrusion configured to protrude further outside from the side surface of the upper shell or the lower shell than the flange portion, to increase a rigidity of the flange portion and the coupling portion, and wherein the upper shell comprises an upper protrusion extended from the at least one coupling protrusion to the upper shell, the upper protrusion forming a portion of the exterior of the compressor, and the upper protrusion comprises a first protrusion and a second protrusion comprising a transition and an approximately flat shape, and the first protrusion has a radius greater than a radius of the transition in the second protrusion.

2. The compressor of claim 1 , wherein the at least one coupling protrusion comprises a first coupling protrusion bent and extended from the flange portion, and a second coupling protrusion bent and extended from the first coupling protrusion.

3. The compressor of claim 1 , wherein the lower shell comprises a lower protrusion extended from the at least one coupling protrusion to the lower shell.

4. The compressor of claim 1 , wherein the upper shell comprises a ceiling protrusion configured to protrude from an upper main portion forming an exterior of the upper shell, to an upper side, to increase a rigidity of the upper shell.

5. The compressor of claim 1 , wherein the at least one coupling protrusion protrudes by a height ranging from one tenth ( 1/10) to five times of a thickness of the lower shell.

6. The compressor of claim 1 , wherein the lower shell comprises a bottom protrusion configured to protrude from a lower main portion forming an exterior of the lower shell, to the outside, to increase a rigidity of the lower shell.

7. The compressor of claim 6 , wherein the bottom protrusion protrudes by a height ranging from one tenth ( 1/10) to five times of a thickness of the lower shell.

8. The compressor of claim 1 , wherein the coupling portion comprises a plurality of first coupling portions disposed to face to each other, wherein the at least one coupling protrusion is provided in plural to correspond to the plurality of first coupling portions.

9. The compressor of claim 8 , wherein the at least one coupling protrusion is provided in plural in at least one first coupling portion among the plurality of first coupling portions.

10. The compressor of claim 1 , wherein the at least one coupling protrusion is integrally coupled to the upper protrusion to form a bead protrusion configured to increase a rigidity of the upper shell.

11. The compressor of claim 1 , wherein the at least one coupling protrusion is inclined.

12. The compressor of claim 1 , wherein the at least one coupling protrusion is stepped.

13. The compressor of claim 1 , wherein:
the coupling portion comprises:
a first coupling portion,
a second coupling portion that includes a length less than a length of the first coupling portion, and
a third coupling portion that includes a curvature and connecting the first coupling portion to the second coupling portion, and

the at least one coupling protrusion is provided in the first coupling portion.

14. The compressor of claim 1 , wherein an outer surface of the upper protrusion is in contact with an inner surface of the at least one coupling protrusion.

15. A compressor comprising:
a housing provided with an accommodating portion configured to accommodate a drive device and a compression device,
wherein the housing comprises a main portion configured to form an exterior of the housing, and a protrusion configured to protrude from the main portion to outside the housing, and
wherein the protrusion comprises:
a first protrusion provided on an edge portion of the protrusion and configured to be bent and extend from an outer surface of the main portion, and
a second protrusion configured to be bent in a same direction as the first protrusion and extend further outside from the outer surface than the first protrusion and comprising a transition and an approximately flat shape, and wherein the first protrusion has a radius greater than a radius of the transition in the second protrusion.

16. The compressor of claim 15 , wherein:
the housing comprises an upper shell and a lower shell configured to form the accommodating portion, a coupling portion provided between the upper shell and the lower shell to allow the upper shell to be coupled to the lower shell, and a part of the protrusion is provided in the coupling portion.

17. The compressor of claim 15 , wherein the protrusion is provided in an upper portion of the housing.

18. The compressor of claim 15 , wherein the protrusion is provided in a bottom portion of the housing.
