Problems solved by technology

[0002] At present, in the industry of fully enclosed refrigeration compressors for refrigerators, the shells used in compressors are generally formed by two cylindrical upper covers and lower shells with oval cross-sections. The centerline of the axis coincides, and the symmetrical centerline of the terminal hole of the lower case in the horizontal direction (also called the centerline of the terminal hole) adopts a design method that coincides with the centerline of the long axis of the ellipse; For the welding process, the welding plane of the machine feet will be designed on both sides of the center line of the oval long axis. With this symmetrical design, the production and related processing technology are relatively simple, and the compressor will also appear symmetrical and beautiful, but it is not good for the space utilization of the shell. Very reasonable, the overall size and weight of the shell also increase accordingly

Abstract

A sealed compressor housing includes a tubular top cover (1) and a tubular lower housing (2) each with an elliptical horizontal cross section that can be snap-fitted together. Major and minor axial centerlines (21, 22) of the top cover (1) and the lower housing (2) respectively coincide with each other. A centerline of a cylinder core of a cylinder block (6) coincides with the major axial centerlines (21). A terminal pin (3) is provided on the lower housing (2) and is disposed axially symmetrical about a centerline (23) of the terminal pin. A top face of the top cover (1) has an asymmetrically spherical shape. A portion of the top face on the side of the terminal pin and a front side of the top face are higher than a rear side thereof. A bottom outer surface of the lower housing (2) has a smooth ellipsoid shape. An angle is formed between the centerline (23) of the terminal pin and the major axial centerlines (21).
