scroll compressor

Abstract

The present invention provides a scroll compressor, comprising: a housing; a driving motor; an orbiting scroll; a fixed scroll, which is combined with the orbiting scroll to form a compression space composed of a suction chamber, an intermediate pressure chamber, and a discharge chamber; a discharge cover, It is provided in the inner space of the housing, and has a space part which is separated from the inner space of the housing and communicates with the discharge chamber. The corresponding side surface has at least one discharge hole that communicates the inside and outside of the space portion with each other. Accordingly, since the oil separator is provided outside the casing, vibration noise of the compressor can be reduced. In addition, compressor efficiency is improved by optimizing the area of ​​the discharge hole and the volume of the space.

Description

technical field [0001] The present invention relates to a scroll compressor, in particular to a scroll compressor in which an oil separation device is arranged in the inner space of a casing. Background technique [0002] A scroll compressor is a compressor in which the fixed scroll is fixed in the inner space of the housing, the orbiting scroll engages with the fixed scroll to orbit, and at the same time, the fixed scroll portion of the fixed scroll and the orbiting scroll Two paired compression spaces consisting of a suction chamber, an intermediate pressure chamber, and a discharge chamber are formed between the orbiting scroll portions. [0003] Compared with other types of compressors, the scroll compressor can obtain a relatively high compression ratio, and the process of suction, compression, and discharge of the refrigerant is performed gently, thereby obtaining a stable torque, so it is used in air-conditioning equipment, etc. It is widely used for refrigerant comp...

AI Technical Summary

Problems solved by technology

[0017] However, the conventional scroll compressor as described above has the following problems: Since the oil separator 90 is provided outside the compressor, the size of the compressor including the oil separator 90 increases, and thus the vibration noise of the compressor increase, and the space occupied by the compressor becomes larger, so that the size of the outdoor unit increases correspondingly or the space utilization rate decreases

Therefore, it is necessary to increase the volume of the oil separator, but there are following problems: as the volume of the oil separator increases, the axial length of the compressor becomes longer, resulting in an increase in the space occupied by the compressor, and the vibration noise of the compressor is also increased. Increase
