Hermetic compressor and manufacturing method thereof

摘要

A hermetic compressor is provided. The hermetic compressor includes a cylindrical shell; a stator fixed to an inner surface of the shell; a rotor rotatably installed with respect to the stator; a compression device combined with the rotor to be rotated together with the rotor; a stationary shaft including an eccentric portion around which the compression device is supported to be stationary with respect to a longitudinal direction thereof; an accumulator fixed to an inside of the shell in such a manner so as to seal an upper end of the shell and fixedly support a first end of the stationary shaft above the stator; a lower frame fixed to the inside of the shell, that fixedly supports a second end of the stationary shaft; an upper cap to seal an upper end of the accumulator; and a lower cap to seal a lower end of the shell.

1. A hermetic compressor, comprising:
a cylindrical shell; a stator fixed to an inner surface of the shell; a rotor rotatably installed with respect to the stator; a compression device combined with the rotor to be rotated together with the rotor; a stationary shaft including an eccentric portion around which the compression device is supported so as to be stationary with respect to a longitudinal direction thereof; an accumulator fixed to an inside of the shell in such a manner as to seal an upper end of the shell and fixedly support a first end of the stationary shaft above the stator; a lower frame fixed to the inside of the shell, that fixedly supports a second end of the stationary shaft; an upper cap to seal an upper end of the accumulator; and a lower cap to seal a lower end of the shell, wherein the accumulator includes a cylindrical accumulator frame with an open upper end, wherein a circumferential wall portion of the accumulator frame rests on the upper end of the shell, and wherein the upper cap rests on the circumferential wall portion.
