Problems solved by technology

On the one hand, it leads to the high oil discharge rate of the compressor, which reduces the energy efficiency of the compressor; on the other hand, the oil level in the oil pool of the compressor is too low, and the pump oil is insufficient, which makes the lubrication of the pump body components insufficient, resulting in the reliability of the compressor. sex decline

Embodiment 1

[0037] This embodiment provides an oil-gas separation structure, such as figure 1 As shown, for the compressor, the oil-gas separation structure includes a first separation assembly 1 and a second separation assembly 2, and an exhaust buffer cavity 3 is formed between the first separation assembly 1 and the casing 5 of the compressor, and the second separation assembly 2 An exhaust oil separation chamber 4 is formed between the first separation assembly 1; the exhaust buffer chamber 3 communicates with the exhaust oil separation chamber 4, and the cross-sectional area of ​​the outlet end of the exhaust buffer chamber 3 is smaller than that of the inlet end of the exhaust oil separation chamber 4 cross-sectional area.

[0038] Specifically, if both the first separation assembly 1 and the second separation assembly 2 are in the shape of a truncated cone, if the first separation assembly 1 is sleeved on the second separation assembly 1, and the upper section of the second separat...

Embodiment 2

[0059] This embodiment provides a compressor, which includes the oil-gas separation structure according to any one of claims 1-8.

[0060] In this embodiment, the oil-gas separation structure in Embodiment 1 is applied to the compressor, so as to prevent the refrigeration oil from circulating in the upper chamber and the lower chamber of the compressor, so that the oil discharge rate of the compressor and the oil level in the oil pool are moderate, The performance of the compressor is guaranteed.

[0061] In specific embodiments:

[0062] The lower end of the second separation assembly 2 is provided with an oil return groove, and the motor support of the compressor is provided with a support groove matching the oil return groove, and the oil return groove and the support groove form an oil passage. Through the matching of the oil return groove and the bracket groove, an oil passage is formed, so that the exhaust oil distribution chamber 4 can communicate with the cavity below...

Embodiment 3

[0069] This embodiment provides an air conditioner, and the air conditioner includes the compressor in Embodiment 2.

Abstract

The invention discloses an oil-gas separation structure, a compressor and an air conditioner, the oil-gas separation structure comprises a first separation assembly and a second separation assembly, an exhaust buffer cavity is formed between the first separation assembly and a shell of the compressor, and an exhaust oil separation cavity is formed between the second separation assembly and the first separation assembly; the exhaust buffer cavity is communicated with the exhaust oil separation cavity, and the cross sectional area of the outlet end of the exhaust buffer cavity is smaller than that of the inlet end of the exhaust oil separation cavity. A cavity in the compressor is divided into an exhaust buffer cavity and an exhaust oil separation cavity through the arrangement of the first separation assembly and the second separation assembly, and the cross section area of the outlet end of the exhaust buffer cavity is smaller than that of the inlet end of the exhaust oil separation cavity; thus, high-pressure gas with refrigerant oil firstly passes through the exhaust buffer cavity and is accumulated at the tail end of the exhaust buffer cavity, and when the gas enters the relatively wide exhaust oil separation cavity from the narrow tail end, the refrigerant oil and the gas can be rapidly separated.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil-gas separation structure, a compressor and an air conditioner. Background technique [0002] Scroll compressors are widely used in the technical field of air conditioners because of their high efficiency, small size, light weight, and stable operation. Its working principle is as follows: multiple crescent-shaped spaces are formed between the movable scroll and the fixed scroll, and the center of the fixed scroll is used as the center of rotation of the movable scroll and a non-rotational rotating flat with a certain radius of rotation. When moving, the crescent-shaped space in the outer circle will continue to move towards the center. At this time, the refrigerant will be gradually pushed to the center space, its volume will continue to shrink and the pressure will continue to rise, until it communicates with the central exhaust hole, and the high-pressure refrigerant...
