no. 1 example

[0021] The rotary compressor will be described below as an example.

[0022] see figure 2 , the compressor includes a compression mechanism and a motor 2 located in the casing, the bottom of the casing gathers refrigerating machine oil, and the compression mechanism includes a compression chamber 3 arranged on the cylinder.

[0023] The bottom of the casing is provided with a partition 7, and the partition 7 and the bottom of the casing together form a cavity, and the refrigerating machine oil gathers on the partition 7 and above the cavity.

[0024] One end of the connecting pipe 4 communicates with the discharge port of the refrigerant gas, the other end of the connecting pipe 4 communicates with one side of the cavity, one end of the discharge pipe 6 opens to the other side of the cavity, and the other end of the discharge pipe 6 communicates with the air conditioning system. connected. The connecting pipe 4 is arranged inside or outside the casing. The discharge pipe 6...

no. 2 example

[0031] see image 3 , in this embodiment, the discharge port of the refrigerant gas is provided on the main casing 8 , and one end of the connecting pipe 4 communicates with the discharge port of the refrigerant gas provided on the main casing 8 .

[0032] See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

no. 3 example

[0034] see Figure 4 , in this embodiment, one end of the discharge pipe 6 is opened on the other side of the cavity, that is, the lower side in the figure, so as to facilitate the oil accumulated between the partition plate 7 and the lower casing 5 to enter the circulation system. The source of oil is entrained in high temperature and high pressure refrigerant gas.

[0035] See the first embodiment for the rest of the undescribed parts, and will not repeat them here.

Abstract

Disclosed is an air exhaust structure of a compressor. The compressor comprises a compressing mechanism positioned in a housing and a motor. Refrigerant oil is gathered at the bottom of the housing. The compressing mechanism comprises a compression cavity arranged on a cylinder. A separator plate is arranged at the bottom of the housing. The separator plate and the bottom of the housing together enclose to form a cavity. Refrigerant oil is gathered on the separator plate and over the cavity. One end of a connecting pipe communicates with a discharge outlet of the refrigerant gas, and the other end of the connecting pipe communicates with one side of the cavity. One end of a discharge pipe is provided with an opening on the other side of the cavity, and the other end of the discharge pipe communicates with an air-conditioning system. The housing is composed of an upper housing, a main housing and a lower housing. The discharge outlet of the refrigerant gas is arranged on the upper housing, or on the main housing, or on the cylinder. The air exhaust structure of the compressor has characteristics of simple and reasonable structure, flexible operation, low manufacturing cost, good safety performance and wide application range.

Description

technical field [0001] The invention relates to a compressor, in particular to an exhaust structure of the compressor. Background technique [0002] Existing compressor, see attached figure 1 , the compressed refrigerant gas coming out of the compression chamber 3 passes through the pressure difference between the compression chamber and the casing, pushes the exhaust valve plate open, and is discharged into the casing of the compressor. The refrigerant gas flows through the motor 2, and finally flows into the condenser of the air conditioning system through the exhaust pipe 6 installed on the upper casing 1 of the compressor. During this process, when the compressed refrigerant gas from the compression chamber 3 flows through the motor 2, it is heated by the motor 2, and the temperature of the refrigerant gas discharged out of the shell is relatively high. On the other hand, the temperature of the refrigerating machine oil accumulated in the lower case 5 is lower than the...
