Abstract:

A hermetically sealed compressor (1) comprises: a vertically-oriented cylindrical compressor main body vessel (10) provided with a discharge pipe (107) and an intake pipe (104) for a refrigerant; an accumulator vessel (25) connected to the intake pipe (104); a compressing unit (12) which is disposed inside the compressor main body vessel (10) and which compresses refrigerant taken in from the accumulator vessel (25) through the intake pipe (104) and discharges the refrigerant from the discharge pipe (107); and a motor (11) which is disposed inside the compressor main body vessel (10) to drive the compressing unit (12). The accumulator vessel (25) includes a cup-shaped accumulator shell (26), and a welded portion (X) where an opening side (26a) of the accumulator shell (26) is joined to the compressor main body vessel (10). A partitioning member (28) for partitioning the interior of the accumulator shell (26) is provided in said interior, and a heat insulating portion (35) for blocking heat transfer from the compressor main body vessel (10) to the accumulator vessel (25) is formed between the partitioning member (28) and a bottom shell (10c) of the compressor main body vessel (10).
