SCROLL COMPRESSOR

摘要

Provided is a scroll compressor having an improved structure in which reliability of a compression portion can be enhanced. The scroll compressor includes a compression unit that compresses a refrigerant introduced into a body, wherein the compression unit may include: a fixed scroll fixed into the body and having an ejection hole and a fixed wrap placed at an outside of the ejection hole; and an orbiting scroll orbiting with respect to the fixed scroll and having an orbiting wrap that constitutes a compression chamber together with the fixed wrap, and wherein the orbiting wrap may include: an outer contact portion formed at an outside surface of the orbiting wrap and being adjacent to the ejection hole; and an inner contact portion formed at an inside surface of the orbiting wrap, being adjacent to the ejection hole and connected to the outer contact portion, and the compression chamber includes a first compression chamber formed when the outer contact portion contacts a first position of an inside surface of the fixed wrap at an ejection starting time of the refrigerant, and the outer contact portion is connected to the inner contact portion along a circumference of a first center circle formed to contact the first position at the ejection starting time of the refrigerant, and a center of the first center circle is placed on a normal line of the first position.

1. A scroll compressor comprising a compression unit that compresses a refrigerant introduced into a body,
wherein the compression unit comprises: a fixed scroll fixed into the body and having an ejection hole and a fixed wrap formed on a surface of the fixed scroll; and an orbiting scroll orbiting with respect to the fixed scroll and having an orbiting wrap that constitutes a compression chamber together with the fixed wrap, and wherein the orbiting wrap comprises:
an outer contact portion formed at an outside surface of the orbiting wrap and being adjacent to the ejection hole; andan inner contact portion formed at an inside surface of the orbiting wrap, the inner contact portion being adjacent to the ejection hole and connected to the outer contact portion, andthe compression chamber comprises a first compression chamber formed when the outer contact portion contacts a first position of an inside surface of the fixed wrap at an ejection starting time of the refrigerant, andwherein the outer contact portion is connected to the inner contact portion along a circumference of a first center circle formed to contact the first position at the ejection starting time of the refrigerant, andwherein a center of the first center circle is placed on a normal line of the first position.
