阅读说明：本技术 涡旋式压缩机 (Scroll compressor having a discharge port ) 是由 李浩源 李康旭 金铁焕 于 2019-05-28 设计创作，主要内容包括：本发明的目的在于提供一种在吐出初始阶段能够确保足够的吐出面积,从而减小吐出阻力的涡旋式压缩机。根据本发明的涡旋式压缩机包括具有固定端板部和固定涡卷部的固定涡旋盘、以及具有回旋端板部和回旋涡卷部的回旋涡旋盘,在固定端板部形成吐出口,并包括连接回旋涡卷部的侧表面与底面的辅助吐出流路,且所述辅助吐出流路与所述吐出口连通,从而使压缩的制冷剂能够通过辅助吐出流路吐出。(The invention aims to provide a scroll compressor which can ensure a sufficient discharge area at the initial stage of discharge so as to reduce the discharge resistance. The scroll compressor according to the present invention includes a fixed scroll having a fixed end plate portion and a fixed scroll wrap, and a orbiting scroll having an orbiting end plate portion and an orbiting scroll wrap, wherein a discharge port is formed in the fixed end plate portion, and an auxiliary discharge flow path connecting a side surface and a bottom surface of the orbiting scroll wrap is included, and the auxiliary discharge flow path communicates with the discharge port, so that a compressed refrigerant can be discharged through the auxiliary discharge flow path.)

1. A scroll compressor, comprising:

A casing having a discharge portion for discharging a refrigerant on one side;

A driving motor coupled to the housing;

A rotating shaft coupled to the driving motor to rotate;

A main frame coupled to an inner circumferential surface of the housing to allow the rotation shaft to pass therethrough;

A fixed scroll including a fixed end plate portion coupled to the housing so as to allow the rotation shaft to pass therethrough, a fixed scroll portion protruding from the fixed end plate portion, and a discharge port penetrating the fixed end plate portion so as to discharge the refrigerant and provided at a distance from the rotation shaft; and

A swirl coil including a swirl end plate portion received in the main frame and coupled to the rotary shaft in a penetrating manner, and a swirl scroll portion protruding from the swirl end plate portion to mesh with the fixed scroll portion,

The orbiting scroll part includes:

A center portion that opens and closes at least a part of the discharge port when the swing end plate portion is swung by the rotating shaft; and

and an auxiliary discharge flow path provided in the central portion and guiding the refrigerant to the discharge port.

2. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided so as to be recessed in the central portion.

3. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided to extend from a side surface of the swirl coil portion toward the discharge port.

4. The scroll compressor of claim 2,

The auxiliary discharge flow path is provided so as to be recessed in the central portion so that there is a region facing the discharge port.

5. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided as a groove in the orbiting scroll.

6. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided so as to form an opening portion on a side surface of the swirl winding portion.

7. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided so as to be recessed at a depth lower than a height at which the swirl lap protrudes from the swirl end plate portion.

8. the scroll compressor of claim 1,

The auxiliary discharge flow path is provided so that the refrigerant flows from the rotary shaft into a portion facing a free end of the fixed scroll.

9. The scroll compressor of claim 1,

The discharge opening includes:

A first discharge port penetrating the fixed end plate portion; and

A second discharge port that is separated from the first discharge port and that penetrates the fixed end plate portion,

The auxiliary discharge flow path is provided so that the refrigerant can flow between the first discharge port and the second discharge port.

10. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided to penetrate the central portion.

11. The scroll compressor of claim 10,

The auxiliary discharge flow path includes:

An inlet flow path penetrating a side surface of the central portion to allow the refrigerant to flow therein; and

And an outlet flow path which communicates the inlet flow path and the discharge port, passes through the central portion, and discharges the refrigerant.

12. The scroll compressor of claim 11,

The inlet flow path and the outlet flow path are arranged inclined to each other.

13. The scroll compressor of claim 11,

the outlet flow path is provided to reduce an area of the central portion contacting the fixed end plate portion.

14. The scroll compressor of claim 11,

the inlet flow path is provided extending from a side surface of the central portion to an inside of the central portion,

The outlet channel extends from the inlet channel to one surface of the central portion that can face the discharge port.

15. The scroll compressor of claim 1,

The auxiliary discharge flow path is provided so that a region facing the fixed end plate portion is wider than a region facing the fixed scroll portion.
