Electric compressor

Abstract

An electric compressor ( 10, 10 A, 10 B, 10 C) includes a suction chamber ( 14 ), a discharge chamber ( 15 ), a compressor body ( 20 ) configured to suck a fluid from the suction chamber ( 14 ), and then, discharge the compressed fluid in to the discharge chamber ( 15 ), an electric motor ( 30 ) configured to drive the compressor body ( 20 ), and an inverter ( 100 ) configured to control the electric motor ( 30 ). The inverter ( 100 ) is disposed in the suction chamber ( 14 ).

1 . An electric compressor comprising:
 a suction chamber, a discharge chamber, a compressor body configured to suck a fluid from the suction chamber and then, discharge the compressed fluid into the discharge chamber, an electric motor configured to drive the compressor body, and an inverter configured to control the electric motor, the inverter being disposed in the suction chamber.   
   
   
       2 . The electric compressor according to  claim 1 , further comprising
 a housing accommodating the compressor body therein and forming the suction chamber and the discharge chamber therein.   
   
   
       3 . The electric compressor according to  claim 2 , wherein
 the inverter includes the inverter case accommodating an inverter circuit therein.   
   
   
       4 . The electric compressor according to  claim 3 , wherein
 an outer circumferential surface of the inverter case is fit on an inner circumferential surface of the housing.   
   
   
       5 . The electric compressor according to  claim 3 , wherein
 the housing includes a first housing formed with a flanged opening end and a second housing formed with a flanged opening end; and   the inverter case is formed with an attached portion attached to the flanges of the first and second housing in a manner that the attached portion is sandwiched between the flanges.   
   
   
       6 . The electric compressor according to  claim 5 , wherein
 an outer circumferential portion of the inverter case is formed to be the attached portion.   
   
   
       7 . The electric compressor according to  claim 4 , wherein
 the inverter case is formed in an annular shape with a through hole at a center thereof.   
   
   
       8 . The electric compressor according to  claim 1 , wherein
 the inverter is disposed between an inlet port serving as an inlet of the suction chamber and an inlet port of the compressor body serving as an outlet of the suction chamber.   
   
   
       9 . The electric compressor according to  claim 1 , wherein
 the electric motor is disposed in the housing.   
   
   
       10 . The electric compressor according to  claim 1 , wherein
 the electric motor is disposed in the suction chamber.   
   
   
       11 . The electric compressor according to  claim 1 , wherein
 the electric motor is disposed in the discharge chamber.   
   
   
       12 . The electric compressor according to  claim 7 , wherein
 the inverter is disposed in a manner that a bearing portion rotatably supporting an drive shaft of the electric motor extends through the through hole of the inverter case.   
   
   
       13 . The electric compressor according to  claim 5 , wherein
 the inverter case is formed in an annular shape with a through hole at a center thereof.
