1. A scroll compressor comprising a housing, a compression mechanism portion, a main frame, a motor, a crankshaft, a main balancing block, and an exhaust pipe,
wherein:
the main frame is located between the compression mechanism portion and the motor;
the main balancing block is arranged around the crankshaft and located between the motor and the main frame;
the motor comprises a rotor and a stator;
the crankshaft passes through the rotor and is connected to the compression mechanism portion;
the stator is mounted in the housing and comprises an iron core mounted in the housing;
an end of the exhaust pipe extends into the housing towards an outer peripheral wall of the main balancing block, and is located between the main frame and the motor;
in an axial direction of the crankshaft, a lower end surface of the main frame is located at a distance H from an upper end surface of the iron core, and a central axis of the exhaust pipe is located at a distance h from the upper end surface of the iron core, where 0.17≤h/H≤0.62; and
in a radial direction of the housing, the exhaust pipe extends into the housing at a depth W, and the outer peripheral wall of the main balancing block is located at a distance L from an inner wall of the housing, where 0.47≤W/L≤0.93.
