Title:
ELECTRIC COMPRESSOR
Document Type and Number:
Japanese Patent JP2013072411
Kind Code:
A
Abstract:

To provide an electric compressor for reducing performance reduction without enlarging the electric compressor.

The electric compressor includes a compression mechanism 4 having a fixed scroll 11 and a turning scroll 12, an electric motor 5 for driving the compression mechanism 4, a body casing 3 for storing the compression mechanism 4 and the electric motor 5, a sub-casing 102 having a partition 112 for constituting a suction passage 61 of a refrigerant with the fixed scroll 11 on the opening side of the body casing 3, an electric motor driving circuit 101 provided on an opposite surface of the suction passage 61 of the partition 112 and driving the electric motor 5, and a connecting space 104 formed in the partition 112 and connecting the electric motor 5 and the electric motor driving circuit 101. Since a heat insulation material 200 is arranged in the connecting space 104, heat transmission to the suction passage 61 side from the connecting space 104 side is reduced, and a thermal influence on the electric motor driving circuit 101 is not deteriorated. Thus, the compression mechanism 4 and the body casing 3 are not enlarged and increased in weight.
