Scroll compressor

Abstract

A scroll compressor includes a partition plate 20, a refrigerant intake tube 13 and a straightening plate 160, and a shielding plate 180 is provided at a height position between the partition plate 20 and an intake portion 38 of a fixed scroll 30. According to this, refrigerant sucked from the refrigerant intake tube 13 flows toward the partition plate 20 by the straightening plate 160, the refrigerant which flows toward the partition plate 20 collides against the shielding plate 180 before it is sucked by a compression mechanism 170 and therefore, it is possible to prevent refrigerant from coming into contact with the partition plate 20 having high temperature. According to this, the refrigerant is not heated by the partition plate 20, volumetric efficiency is enhanced and high efficiency of the compressor can be realized.

1 . A scroll compressor comprising:
 a partition plate for dividing an interior of an airtight container into a high-pressure space and a low-pressure space;   a fixed scroll which is adjacent to the partition plate;   an orbiting scroll which is meshed with the fixed scroll and which forms a compression chamber;   a rotation-suppressing member for preventing the orbiting scroll from rotating; and   a main bearing for supporting the orbiting scroll; in which   the fixed scroll, the orbiting scroll, the rotation-suppressing member and the main bearing are placed in the low-pressure space, and   the fixed scroll and the orbiting scroll are placed between the partition plate and the main bearing, wherein   a refrigerant intake tube for making the low-pressure space suck refrigerant is provided in the airtight container, and   the scroll compressor includes a straightening plate against which refrigerant introduced from the refrigerant intake tube collides, and a shielding plate provided at a height position between the partition plate and an intake portion of the fixed scroll.   
     
     
         2 . The scroll compressor according to  claim 1 , wherein the shielding plate is provided on an inner wall of the airtight container. 
     
     
         3 . The scroll compressor according to  claim 1 , wherein the shielding plate is provided in the fixed scroll. 
     
     
         4 . The scroll compressor according to  claim 1 , wherein the shielding plate covers an upper opening of the straightening plate and covers an opening range of the intake portion of at least the fixed scroll. 
     
     
         5 . The scroll compressor according to  claim 1 , wherein the straightening plate and the shielding plate are integrally formed together.
