Fixed scroll of scroll compressor

Abstract

Disclosed herein is a scroll compressor, and more particularly, a fixed scroll of the scroll compressor which can allow part of gaseous refrigerant to be smoothly introduced into a compression chamber while preventing introduction of the remaining gaseous refrigerant that is heated in the compressor. The fixed scroll includes a scroll body having an involuted wrap to define a compression chamber therein and provided, around a lower end thereof, with a mounting flange to be arranged on an upper surface of a main frame, and an interceptive suction portion configured to guide part of the gaseous refrigerant, that is directed upward along the main frame, into the compression chamber while preventing introduction of the remaining gaseous refrigerant that is circulated around the scroll body.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] Pursuant to 35 U.S.C. § 119(a), this application claims the benefit of earlier filing date and right of priority to Korean Patent Application No. 10-2005-0026583, filed on Mar. 30, 2005, the content of which is hereby incorporated by reference herein in its entirety. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a scroll compressor, and more particularly, to a fixed scroll of a scroll compressor which can allow gaseous refrigerant, that is introduced into a compressor shell via a suction pipe, to be directly introduced into a compression chamber without being heated. [0004] 2. Description of the Related Art [0005]FIG. 1 is a longitudinal sectional view illustrating important parts of a conventional scroll compressor. FIG. 2 is a perspective view illustrating a fixed scroll of FIG. 1. [0006] Arrows shown in FIGS. 1 and 2 indicate a flow direction of suctioned gaseous refrigerant. [00...

AI Technical Summary

Benefits of technology

[0013] Therefore, the present invention has been made in view of the above problems, and it is an object of the present invention to provide a fixed scroll of a scroll compressor which can allow suctioned gaseous refrigerant to be effectively introduced into a compression chamber while preventing introduction of gaseous refrigerant that is heated in the compressor.

[0014] It is another object of the present invention to provide a fixed scroll of a scroll compressor which can achieve smooth introduction of suctioned gaseous refrigerant into a compression chamber while preventing introduction of heated gaseous refrigerant via a simple deformation in the shape of the fixed scroll without requiring installation of an additional member.

Problems solved by technology

The conventional scroll compressor configured as stated above, however, has a problem that suctioned gaseous refrigerant, that strikes the suction baffle, is not introduced directly into the compression chamber, but is circulated along an outer circumference of the scroll body, resulting in ineffective introduction of the gaseous refrigerant into the compression chamber.

This considerably degrades the volumetric efficiency of the compressor, resulting in deterioration in the overall performance of the compressor.
