Problems solved by technology

[0007] However, in the conventional structure, there is the following technical problem: the high-temperature and high-pressure refrigerant gas compressed by the compression mechanism part flows through the motor part, so the motor part is heated by the refrigerant gas, causing the efficiency of the motor part to decrease.

Embodiment approach 1

[0055] figure 1 It is a longitudinal sectional view of the compressor according to Embodiment 1 of the present invention. Such as figure 1 As shown, the compressor of this embodiment includes a compression mechanism unit 10 for compressing refrigerant gas and a motor unit 20 for driving the compression mechanism unit 10 in the airtight container 1 . The inside of the airtight container 1 is divided into one container inner space 31 and the other container inner space 32 by the compression mechanism unit 10 . Furthermore, the motor unit 20 is arranged in the other container inner space 32 . In addition, the other container inner space 32 is divided into a compression mechanism side space 33 and an oil storage side space 34 by the motor unit 20 . Furthermore, the oil reservoir 2 is arranged in the oil reservoir side space 34 . In the airtight container 1, the suction pipe 3 and the discharge pipe 4 are fixed by welding. The suction pipe 3 and the discharge pipe 4 communicat...

[0073] image 3 It is an enlarged cross-sectional view of a main part of a compression mechanism unit of a compressor according to Embodiment 2 of the present invention. The basic structure of this embodiment and figure 1 The same, so the description is omitted. Additionally, for figure 1 with figure 2 The structures that are the same as those described will be given the same symbols, and part of the description will be omitted.

[0074] In the present embodiment, the outer peripheral portion of the fixed scroll 12 is bored with a stepped portion, whereby the first cylindrical space 41c and the delivery port 43a are formed. The first cylindrical space 41c is formed by processing a non-through hole from the end surface on the side of the fixed surface of the main bearing member 11 (end surface on the side of the overlapping portion). The delivery port 43a, from the end surface on the fixed side of the main bearing member 11 (end surface on the side of the overlapping port...

Abstract

Provided is a compressor equipped with an oil separation mechanism unit (40) that separates oil from a refrigerant gas discharged from a compression mechanism part (10), with the oil separation mechanism unit (40) having: a cylindrical space (41) in which the refrigerant gas is caused to rotate; an inflow part (42) that introduces the refrigerant gas discharged from the compression mechanism part (10) into the cylindrical space (41); a delivery outlet (43) that delivers the refrigerant gas, from which the oil has been separated, from the cylindrical space (41) to one space (31) within a container; and a discharge port (44) that discharges the separated oil from the cylindrical space (41) to the other space (32) within the container. The delivery outlet (43) is provided with an impactor (49) with a prescribed distance therebetween. Thus, the electric motor part is highly efficient, and the compressor has improved volumetric efficiency and low oil circulation.

Description

technical field [0001] The present invention relates to a compressor provided with an oil separation mechanism for separating oil from refrigerant gas discharged from the compression mechanism. Background technique [0002] In the prior art, a compressor used in an air conditioner or a cooling device generally includes a compression mechanism unit and a motor unit driving the compression mechanism unit in a casing, and the refrigerant gas returned from the refrigeration cycle is cooled by the compression mechanism unit. compressed and fed into the refrigeration cycle. Generally speaking, the refrigerant gas compressed by the compression mechanism part flows temporarily around the motor to cool the motor part, and then is sent into the refrigeration cycle from a discharge pipe provided in the casing (for example, refer to the patent document 1). That is, the refrigerant gas compressed by the compression mechanism unit is discharged from the discharge port to the discharge s...
