Abstract

A compressor provided with an oil stabilizing member capable of preventing oil stored in an oil storage space from being scattered is provided. A compressor may include a closed container provided with an inlet port and an outlet port, a compression unit configured to compress refrigerant introduced into an inside the closed container through the inlet port, a driving unit configured to provide a driving force to drive the compression unit, a rotating shaft configured to deliver the driving force to the compression unit, an oil storage space formed at a lower portion of an inside the closed container and configured to store a predetermined oil to come into contact with one end portion of the rotating shaft, and an oil stabilizing member installed so as to move along a surface of oil formed at the oil storage space, thereby preventing the oil from being scattered and thus released through the outlet port, wherein the oil stabilizing member floating on the surface of the oil prevents oil from being scattered upward according to operation of the compressor.

First claim

What is claimed is:

1. A compressor, comprising:
a fixed scroll fixed at an inside of a closed container;
an orbiting scroll configured to compress refrigerant while revolving relative to the fixed scroll;
a rotating shaft to deliver a rotating force to the orbiting scroll;
a guide inserted around the rotating shaft and comprising at least one vertically extending groove; and
an oil stabilizing member which includes at least one protrusion that is inserted into the at least one vertically extending groove which enables the oil stabilizing member to move vertically along the at least one groove to prevent oil stored at a lower portion of the inside of the closed container from being scattered.

2. A compressor, comprising:
a fixed scroll fixed at an inside of a closed container;
an orbiting scroll configured to compress refrigerant while revolving relative to the fixed scroll;
a rotating shaft to deliver a rotating force to the orbiting scroll;
upper and lower flanges fixed to upper and lower end portions of an inner side of the closed container to rotatably support the rotating shaft;
an oil stabilizing member movably installed at an upper portion of the lower flange to prevent oil stored at a lower portion of the inside of the closed container from being scattered; and
a guide inserted around the rotating shaft to be coupled to the lower flange,
wherein the guide is positioned between the oil stabilizing member and the rotating shaft.

3. The compressor of claim 2 , wherein:
the oil stabilizing member moves up and down along the rotating shaft according to flow of the oil.

4. The compressor of claim 2 , wherein:
the guide is coupled to the lower flange by use of at least one screw, and is provided at a lower portion thereof with at least one screw coupling part to which the at least one screw is coupled.

5. The compressor of claim 4 , wherein:
the guide comprises at least one groove vertically extending, and the oil stabilizing member comprises at least one protrusion that is inserted into the at least one groove to move vertically along the at least one groove.

6. The compressor of claim 5 , wherein:
the guide comprises a fixing step positioned at an upper portion of the at least one groove to fix an upward movement of the at least one protrusion to prevent the oil stabilizing member from being separated from the guide.

7. The compressor of claim 6 , wherein:
the oil stabilizing member comprises at least one penetrating groove that corresponds to the at least one screw coupling part, so that the at least one protrusion is insertedly coupled to the at least one groove at a lower portion of the guide.

8. A compressor comprising:
a closed container provided with an inlet port and an outlet port;
a compression unit configured to compress refrigerant introduced into an inside of the closed container through the inlet port;
a driving unit configured to provide a driving force to drive the compression unit;
a rotating shaft configured to deliver the driving force to the compression unit;
an oil storage space formed at a lower portion of the inside of the closed container and configured to store a predetermined oil while in contact with one end portion of the rotating shaft;
an oil stabilizing member installed so as to move along a surface of oil formed at the oil storage space, thereby preventing the oil from being scattered and thus released through the outlet port, and the oil stabilizing member having a coupler allowing the rotating shaft to be inserted thereinto after passing therethrough, wherein the oil stabilizing member is moved along the rotating shaft in response to flow of the oil;
a guide configured to guide the movement of the oil stabilizing member and positioned between the coupler and the rotating shaft; and
a lower flange coupled to a lower portion of an inner side of the closed container to rotatably support a lower portion of the rotating shaft with respect to the closed container,
wherein the guide is inserted around the rotating shaft and fixedly coupled to the lower flange.

9. The compressor of claim 8 , wherein:
the guide comprises at least one moving groove, and
the oil stabilizing member comprises at least one moving protrusion protruding from the coupler toward the guide, so that the at least one moving protrusion is inserted into the at least one moving groove, thereby coupling the oil stabilizing member to the guide.

10. The compressor of claim 9 , wherein:
the at least one moving groove is formed in a longitudinal direction, and the oil stabilizing member is moved in a longitudinal direction along the at least one moving groove.

11. The compressor of claim 10 , wherein:
the guide comprises a fixing step positioned at an upper portion of the at least one moving groove to fix an upward movement of the at least one moving protrusion moving along the at least one moving groove.

12. The compressor of claim 8 , wherein:
the guide comprises at least one screw coupling part to be coupled to the lower flange, and the at least one screw coupling part circumferentially protrudes at a lower portion of the guide.

13. The compressor of claim 12 , wherein:
the oil stabilizing member comprises at least one penetrating groove that is formed at the coupler while having a shape corresponding to the at least one screw coupling part, so that the oil stabilizing member is coupled to the guide after passing through the at least one screw coupling part.
