Electric compressor

Abstract

To stop deterioration in position accuracy of a mounting portion. An electric compressor 1 includes an electric motor 10, a compression mechanism 20 driven by the electric motor 10, an inverter 30 that drives the electric motor 10, a casing 40 in which the electric motor 10, the compression mechanism 20, and the inverter 30 are housed, and a mounting portion 50 that is formed in the casing 40 and mounts the casing 40 to a predetermined object C. The casing 40 includes a motor casing 41 in which the electric motor 10 is housed, a compression mechanism casing 42 in which the compression mechanism 20 is housed, and an inverter casing 43 in which the inverter 30 is housed. The mounting portion 50 includes a first mounting leg 51 provided in the compression mechanism casing 42 and a second mounting leg (52, 52) provided in the inverter casing 43.

1 . An electric compressor comprising: an electric motor; a compression mechanism driven by the electric motor; an inverter that drives the electric motor; a casing in which the electric motor, the compression mechanism, and the inverter are housed; and a mounting portion that is formed in the casing and mounts the casing on a predetermined object, wherein
 the casing includes a motor casing in which the electric motor is housed, a compression mechanism casing in which the compression mechanism is housed, and an inverter casing in which the inverter is housed, and   the mounting portion includes a first mounting leg provided in the compression mechanism casing and a second mounting leg provided in the inverter casing.   
     
     
         2 . The electric compressor according to  claim 1 , wherein
 the number of the first mounting legs is one, and the number of the second mounting legs is two.   
     
     
         3 . The electric compressor according to  claim 1 , wherein
 a seat portion having a seating face in contact with the object is formed at a distal end of the first mounting leg and the second mounting leg, and   a female screw is formed in the seat portion, and   the seating face of the first mounting leg and the seating face of the second mounting leg are located on an equal virtual plane.   
     
     
         4 . The electric compressor according to  claim 1 , wherein
 the inverter casing protrudes toward an object side from an outer surface of the compression mechanism casing and an outer surface of the motor casing, and   a total length of the first mounting leg is longer than a total length of the second mounting leg, and   the first mounting leg includes a leg main body formed in a columnar shape, and a reinforcing rib extending in a leg portion lateral direction along an outer surface of the leg main body.   
     
     
         5 . The electric compressor according to  claim 4 , wherein
 the motor casing is provided between the compression mechanism casing and the inverter casing,   the compression mechanism casing includes a cylindrical portion surrounding a periphery of the compression mechanism, and   the reinforcing rib of the first mounting leg includes a first rib extending in the leg portion lateral direction along a motor casing side portion of an outer surface of the leg main body and a second rib and a third rib orthogonal to the first rib.   
     
     
         6 . The electric compressor according to  claim 5 , wherein the first rib, the second rib, and the third rib are formed away from an outer surface of the leg main body toward the cylindrical portion of the compression mechanism casing. 
     
     
         7 . The electric compressor according to  claim 5 , wherein the first rib includes a rib main body formed so as to be away from an outer surface of the leg main body toward the cylindrical portion of the compression mechanism casing, and a rib root connecting the rib main body to an outer surface of the cylindrical portion of the compression mechanism casing, the rib root extending from the outer surface of the leg main body to a motor-casing-side end face position of the cylindrical portion. 
     
     
         8 . The electric compressor according to  claim 1 , wherein
 the object is located above the casing, and   the casing is suspended below the object via the mounting portion.
