Abstract

A vortex-type compressor with detachable lower supporter is disclosed. Its cylindrical lower supporter under stator and rotor has flange jaws on its top. Said flange jaws have screen hole for fixing iron core of stator. The lower part of motor shaft is positioned in the central hole on bottom of lower supporter. A ring recess on the bottom of lower supporter is used to recept a lower balance block of lower end of rotor. Its advantages are low cost and preventing reverse rotation.

Description

technical field [0001] The invention belongs to compressors, in particular to a scroll compressor. Background technique [0002] The present invention relates to a scroll compressor, and Fig. 1 shows a longitudinal sectional view of a scroll compressor in the prior art. As shown in the figure, the scroll compressor has the following structure: the inside of the casing 10 is a closed space; the compression part 20 is above the inside of the casing 10 and compresses the refrigerant sucked from the outside; the motor 30 is arranged on the compression part 20 Below, the compression member 20 is driven. [0003] The suction pipe 11 is located on the side of the casing 10 and can suck in refrigerant from the outside; the exhaust pipe 12 is located above the suction pipe 11 and can discharge the refrigerant compressed by the compression unit 20 . [0004] The compression part 20 includes a fixed scroll 21 and an orbiting scroll 23 . The fixed scroll 21 is fixed above the inside ...
