ELECTRIC COMPRESSOR AND REFRIGERATING DEVICE HAVING SAME

摘要

Disclosed is an electric compressor (1), comprising an electric motor (3) provided with a stator (4) and a rotor (30); a compression mechanism (5) having an eccentric shaft (10) rotatably connected with the rotor (30) in a sliding way and an internally provided compression cavity (51) used for driving the compression via the eccentric shaft (10); and a torque buffer device (41) connecting the rotor (30) and the eccentric shaft (10). In the compressing process of the compression cavity (51), the difference between the rotation angle (θ1) of the eccentric shaft (10) and the rotation angle (θ2) of the rotor (30) is a phase angle (θ3), and the phase angle (θ3) will increase or decrease. Further disclosed is a refrigerating device having the above-mentioned electric compressor.
