[0027] To further illustrate the embodiments, the present application provides drawings. These drawings are part of the disclosure of the present application, which mainly serve to illustrate the embodiments, and can be explained in conjunction with the related description of the specification to explain the operating principle of the embodiments. With reference to these contents, those skilled in the art should understand other possible implementations and advantages of the present application.

[0028] In the related art, due to the horizontal installation characteristic, the overall height of the horizontal compressor is greatly reduced compared with the vertical compressor, which can be conveniently used in refrigeration, refrigeration, vehicle and other scenes. At present, the exhaust pipe of the horizontal compressor on the market is generally installed at the bottom of the pump body structure at the opposite end of the motor. The bottom of the horizontal compressor is the area for storing refrigeration oil. If the exhaust pipe is improperly arranged, it may cause the oil discharge of the compressor to be large, the performance to be reduced, and the installation difficulty to be increased. In addition, some models choose to install the exhaust pipe at the top of the compressor shell, and improve the poor installation problem by bending the exhaust pipe at right angles for multiple times, which increases the overall height of the horizontal compressor, thereby increasing the space occupied by the horizontal compressor in the vertical direction and increasing the exhaust resistance of the exhaust pipe, which is not conducive to the performance of the compressor.

[0029] Therefore, the horizontal compressor with the elbow assembly 20 provided in the embodiments of the present application can reduce the flow loss of the fluid to reduce the exhaust resistance, effectively improve the performance of the whole machine, and optimize the installation of the elbow assembly 20 to reduce the overall height of the whole machine.

The central angle of the second arc-shaped elbow pipe 24 is α, and 30°≤α≤150°.

[0032] In addition, in the embodiments of the present application, the central angle of the first arc-shaped elbow pipe 23 is β, and 40°≤β≤120°.
