Inverter type scroll compressor

Abstract

The present invention relates to an inverter type scroll compressor and comprises a housing, a fixed scroll which is set up inside the housing, an orbiting scroll which orbits around the fixed scroll, a driving unit which turns the orbiting scroll, an intake port and a discharge port which are in the housing, and an inverter which faces the front surface of the fixed scroll. An intake hole penetrating to the compression chamber and a discharge hole are respectively formed in the fixed scroll and the orbiting scroll. Accordingly, the present invention is configured so that the coolant is discharged through the discharge hole after the coolant passes through the inverter and the fixed scroll and then flows into the compression chamber.

1 . An inverter type scroll compressor comprising:
 a housing;   a fixed scroll fixed to and installed within the housing;   an orbiting scroll configured to orbit with respect to the fixed scroll;   a drive unit configured to drive and orbit the orbiting scroll;   a suction port and a discharge port formed in the housing; and   an inverter disposed on the front surface of the fixed scroll to be opposite to the fixed scroll,   wherein a suction opening is formed in the fixed scroll to penetrate the fixed scroll to the compression chamber, a discharge opening is formed in the orbiting scroll, and coolant is discharged through the discharge opening after introduced into the compression chamber through the suction opening via a gap between the inverter and the fixed scroll.   
     
     
         2 . The inverter type scroll compressor as claimed in  claim 1 , wherein a guide for guiding the coolant suctioned from the suction port to the suction opening is formed on a front wall of the fixed scroll opposite to the inverter. 
     
     
         3 . The inverter type scroll compressor as claimed in  claim 2 , wherein an introduction opening communicated with the suction opening of the fixed scroll is formed in the guide. 
     
     
         4 . The inverter type scroll compressor as claimed in  claim 3 , wherein, when seen from the direction of the drive shaft, a plurality of guide channels extends around the guide. 
     
     
         5 . The inverter type scroll compressor as claimed in  claim 4 , wherein one end of at least one of the guide channels is disposed near the suction port and an opposite end thereof is disposed near the introduction opening. 
     
     
         6 . The inverter type scroll compressor as claimed in  claim 5 , wherein at least one section of the guide channel is arcuate. 
     
     
         7 . The inverter type scroll compressor as claimed in  claim 5 , wherein at least one of the guide channels has a linear introduction section on the side of the suction port. 
     
     
         8 . The inverter type scroll compressor as claimed in  claim 4 , wherein the guide channels are formed by a plurality of guide strips or guide grooves. 
     
     
         9 . The inverter type scroll compressor as claimed in  claim 1 , wherein the discharge port is formed on the rear side of the orbiting scroll. 
     
     
         10 . The inverter type scroll compressor as claimed in  claim 1 , wherein the drive unit includes a drive shaft and a discharge passage passes through the drive shaft along the lengthwise direction thereof. 
     
     
         11 . The inverter type scroll compressor as claimed in  claim 10 , wherein at least one section of the discharge passage formed in the drive shaft is inclined from the axis of the drive shaft to the outside as it goes from the rear side to the front side.
