Embodiment Construction

[0019] The following pass figure 1 One embodiment of the hermetic compressor and its manufacturing method of the present invention will be described through FIG. 6 .

[0020] The hermetic compressor 40 is a rotary hermetic compressor, and includes a compressor main body 41 and a gas-liquid separator 4 . The hermetic compressor 40 constitutes a part of a refrigerating cycle of a refrigerating machine such as an air conditioner or a refrigeration application product. In addition, the present invention is not limited to the rotary type, but can be applied equally to turbo type and reciprocating type hermetic compressors.

[0021] The compressor main body 41 is configured by accommodating the motor unit 32 and the compression mechanism unit 31 in the airtight container 30 . The motor unit 32 is configured by including a stator 5 and a rotor 6 . The stator 5 is fixed by, for example, being fit in the container tube member 2 , and the rotor 6 is fixed by press-fitting the cranksh...

Abstract

A HERMETIC COMPRESSOR HAS A CLOSED HOUSING FORMED BY WELDING A HOUSING LOWER MEBER TO A HOUSING CYLINDER MEMBER, AND HOUSE A COMPRESSOR MECHANISM SECTION AND AN ELECTRIC MOTOR SECTION IN THE CLOSED HOUSING. IN THE HERMETIC COMPRESSOR, THE HOUSING LOWER MEMBER IS MADE BY UNITARILY FORMING, FROM ONE MEMBER, A BASE, A FITTING SECTION FORMED ON THE OUTER PERIPHERY OF THE BASE FOR FITTING TO THE HOUSING CYLINDER MEMBER, AND A LEG SECTION FORMED OUTWARDLY OF THE FITTING SECTION. THEREFORE, HERMETIC COMPRESSOR IS CAPABLE OF COST REDUCTION AND IMPROVEMENTS IN RELIABILITY.(FIGURE 1)

Description

technical field [0001] The present invention relates to a hermetic compressor and a manufacturing method thereof, and is particularly suitable for a hermetic compressor and a manufacturing method thereof for refrigerators used in air conditioners, cold air application products, and the like. Background technique [0002] A conventional hermetic compressor has the following structure: a container lower part and a container upper part are welded to a container tube part to form an airtight container, and the compressor part and the motor part are accommodated in the airtight container, and the container lower part is separated The frame part is welded on the lower part of the container to form a hermetic compressor, wherein the lower part of the container has a base and a fitting part, and the fitting part stands up from the outer periphery of the base and fits inside the lower end part of the container tube part, And the lower end of the fitting part is welded, and the frame ...
