Hermetic type compressor

Abstract

A compressor main body container includes a main shell having a vertical cylindrical shape, a top shell having a cup shape, and a bottom shell having a cup shape, and an interior portion of the main shell is hermetically sealed by securing an opening side of the top shell to an upper end portion of the main shell at a first welded portion by welding, and securing an opening side of the bottom shell to a lower end portion of the main shell at a second welded portion by welding. The accumulator container includes an accumulator shell having a cup shape, and an interior portion of the accumulator shell is hermetically sealed by securing an opening side of the accumulator shell to an opposite opening side of the bottom shell at a third welded portion by welding at a position lower than a position of the second welded portion in the compressor main body container.

1 . A hermetic type compressor
 in which, in an interior portion of a compressor main body container having a vertical cylindrical shape, a compression section that sucks and compresses a refrigerant and that discharges the refrigerant into the compressor main body container, and a motor that drives the compression section are accommodated, and   that includes, below the compressor main body container, an accumulator container that separates a refrigerant, sucked from a refrigeration cycle, into a gas refrigerant and a liquid refrigerant, and that supplies the gas refrigerant to the compression section, wherein   the compressor main body container includes a main shell having a vertical cylindrical shape, a top shell having a cup shape, and a bottom shell having a cup shape, and in which   an interior portion of the main shell is hermetically sealed by securing an opening side of the top shell to an upper end portion of the main shell at a first welded portion by welding, and further by securing an opening side of the bottom shell to a lower end portion of the main shell at a second welded portion by welding,   the accumulator container includes an accumulator shell having a cup shape, and in which   an interior portion of the accumulator shell is hermetically sealed by securing, by welding, an opening side of the accumulator shell to an opposite opening side of the bottom shell at a third welded portion that is located at a position lower than a position of the second welded portion in the compressor main body container,   the first welded portion, the second welded portion, and the third welded portion are exposed to an outside of the compressor main body container, and   the second welded portion and the third welded portion are positioned away from each other to avoid contact therebetween.   
     
     
         2 . A hermetic type compressor
 in which, in an interior portion of a compressor main body container having a vertical cylindrical shape, a compression section that sucks and compresses a refrigerant and that discharges the refrigerant into the compressor main body container, and a motor that drives the compression section are accommodated, and   that includes, below the compressor main body container, an accumulator container that separates a refrigerant, sucked from a refrigeration cycle, into a gas refrigerant and a liquid refrigerant, and that supplies the gas refrigerant to the compression section, wherein   the compressor main body container includes a main body, in which a main shell having a vertical cylindrical shape and a bottom shell having a cup shape are integrally formed by performing press molding, and a top shell having a cup shape, and in which   an interior portion of the main body is hermetically sealed by securing an opening side of the top shell to an upper end portion of the main shell at a welded portion for the main body by welding, and   the accumulator container includes an accumulator shell having a cup shape, and in which   an interior portion of the accumulator shell is hermetically sealed by securing an opening side of the accumulator shell to an outer circumference wall of the bottom shell at a welded portion for the accumulator by welding,   the welded portion for the main body and the welded portion for the accumulator are exposed to the outside of the compressor main body container, and   the compressor main body container is not provided with a different welded portion that is for welding the accumulator shell to a different member and that is formed to contact with the welded portion for the accumulator.
