Electric compressor having an internal flow path arranged on an opposite side of a suction port relative to a first plane

An electric compressor comprising:

• a motor that generates power;
• a compression mechanism that receives the power from the motor and compresses a refrigerant;
• and
• an inverter that controls the motor, wherein a housing receiving the motor and the inverter includes a partition wall that divides a motor receiving space where the motor is received and an inverter receiving space where the inverter is received, and a suction port that introduces refrigerant from outside to the motor receiving space, wherein at least one internal flow path is formed between an inner circumferential surface of the housing and an outer circumferential surface of the motor, wherein the internal flow path and the suction port are formed on opposite sides of each other with respect to a first plane, that is, an imaginary plane which includes a central axis of the housing and is perpendicular to a ground surface, wherein the housing is divided into a housing first portion located on one side of the first plane and a housing second portion located on a side opposite to the housing first portion, wherein an annular wall of the housing, which supports the outer circumferential surface of the motor, includes an annular wall first portion included in the housing first portion and an annular wall second portion included in the housing second portion, the suction port is formed in the annular wall first portion, and the internal flow path is formed in the annular wall second portion, wherein the partition wall further comprises a rib which protrudes from a surface facing the motor receiving space, wherein the rib further comprises a first rib which extends in a circumferential direction of the motor receiving space, wherein the first rib is formed in plural numbers, and the plurality of first ribs are formed apart from each other in a radial direction of the motor receiving space, and wherein a farther a distance at least one of the plurality of first ribs is from the suction port in the circumferential direction of the motor receiving space, a radius of curvature of the first rib decreases more.
