Sealing type compressor

Abstract

The sealed compressor of the invention comprises the following components: a driving unit which is arranged at the inner side of the sealed container that is formed with an engine oil storing space at the bottom surface; a compressing unit which receives the driving force of the driving unit and do compression to the cryogen; a rotating shaft which transfers the driving force of the driving unit to the compressing unit and guides the engine oil in the engine oil storing space to the tucking part of the compressing unit and the driving unit; an eccentric shaft part which is arranged eccentrically at the lower end of the rotating shaft; and an oil sucking component which is connected to the lower end of the eccentric shaft in order to suck the engine oil in the engine oil storing space to the engine oil flow circuit, the oil sucking component comprises the following components: a press-in part which is arranged parallel to the length direction of the rotating shaft with the mode that the press-in part is combined with the eccentric shaft part; and an absorbing part which sustains a straight lien shape between the upper end and the lower end, and bends from the lower bending of the press-in part according to the mode that the center of the lower end and the axle core of the rotating shaft are consistent.

Description

Technical field [0001] The present invention relates to a hermetic compressor, and more particularly, to a hermetic compressor configured to effectively reduce noise generated by oil pick-up by improving the structure of an oil pick-up member of the hermetic compressor. Background technique [0002] Generally, a hermetic compressor used in a refrigerating cycle device such as a refrigerator or an air conditioner has an appearance by forming a sealed container with an organic oil storage space on the bottom surface. [0003] A drive unit that provides compression driving force of the refrigerant and a compression unit that receives the drive force from the drive unit and performs the compression action of the refrigerant are arranged inside the sealed container. The drive force of the drive unit is transmitted to the compressor through the rotating shaft. unit. [0004] The rotating shaft is provided with its upper part pressed into the rotor of the drive unit. The compression uni...

Problems solved by technology

[0008] However, in this conventional hermetic compressor, the center of the lower end of the absorbing portion 4b of the above-mentioned oil absorbing member 4 is located outside the shaft core C of the rotating shaft 1, so when the rotating shaft 1 rotates, the absorbing portion 4b of the oil absorbing member 4 opposes the oil surface. The problem of too much churn

[0009] In addition, when the oil absorbing member 4 rotates, a vortex having a shape corresponding to the shape outside the absorbing portion 4b is formed on the oil surface on the outside of the absorbing portion 4b. However, the oil absorbing member 4 of this conventional hermetic compressor is arranged as Since it protrudes outward to have a predetermined curvature, there is a problem that the vortex formed outside the absorbing portion 4b becomes larger corresponding to the portion protruding outward in this way.

[0010] Thereby, because of the structure of this oil-absorbing member, this hermetic compressor has the following problems, that is, when the oil-absorbing member performs oil-absorbing action, the machine oil on the oil surface of the machine oil is excessively splashed and a large vortex is formed, thereby causing 4-5KHz vibration. loud noise
