Compressor

Abstract

The present invention discloses a compressor, comprising: a sealed housing having a discharge space for discharging a refrigerant gas; an electric part, arranged in the sealing shell and provides rotary driving force; a compression unit that is provided inside the sealed case and compresses the refrigerant gas; and a rotating shaft for operating the compression unit by means of the rotational driving force of the electric unit, the rotating shaft having formed therein a refrigerant flow path for guiding the refrigerant gas compressed by the compression unit to the discharge space. With this configuration, the refrigerant gas can be directly discharged to the discharge space without passing through other locations, thereby minimizing flow resistance.

Description

technical field [0001] The present invention relates to a compressor applying an improved refrigerant guiding structure. Background technique [0002] In general, a compressor is a machine for generating high-pressure or delivering high-pressure fluid, etc., and in the case of a compressor applied to a refrigeration cycle of a refrigerator or an air conditioner, etc., performs a function of compressing refrigerant gas and transferring it to a condenser. [0003] Such compressors are classified into a reciprocating compressor, a rotary compressor, a scroll compressor, and the like according to a method of compressing refrigerant gas. [0004] In particular, the scroll compression mechanism is such that a fixed scroll is fixed in the inner space of the airtight container, and the orbiting scroll engages with the fixed scroll and rotates, and the fixed scroll and the fixed scroll The compression chambers continuously formed between the orbiting wraps of the orbiting scroll con...

Problems solved by technology

[0010] However, in the aforementioned prior art compressor, in order to form a flow path that guides the compressed refrigerant gas to the discharge space, there is a process of forming a plurality of refrigerant flow paths in the main frame, the fixed scroll, and the like. Difficulty, and in order to make the above-mentioned various refrigerant flow paths communicate with each other, there are difficulties in manufacturing that need to accurately install each component, etc.

[0011] In addition, in the above-mentioned prior art compression mechanism, the oil existing in the lower space (the space below the discharge cover) in the sealed casing is pumped to each sliding part while the rotating shaft rotates. The above-mentioned rotating shaft needs to pass through the discharge cover, so it is necessary to add a structure for keeping the penetration part sealed, and the structure of the discharge cover becomes very complicated.

[0012] In addition, the above-mentioned conventional compressor has a problem that the refrigerant gas discharged into the discharge cover passes through the space where the electric unit is located after passing through the refrigerant flow path of the fixed scroll and the main frame. , when meeting with the oil drawn down by each sliding part, it cannot flow smoothly to the upper space inside the sealed case, and part of the oil mixed with it is discharged to the outside through the refrigerant discharge pipe.

[0013] In addition, there is a disadvantage that an oil separation guide for separating oil and refrigerant gas needs to be provided between the electric part and the main frame in the interior of the sealed case to prevent the oil and refrigerant gas from being mixed issues together

[0014] In addition, the aforementioned prior art compressor has the problem that the high-speed performance cannot be improved due to excessive flow resistance when the refrigerant gas discharged into the discharge cover sequentially passes through the compression unit and the electric unit.
