The utility model provides a compressor 10, this compressor 10 includes compressor main part 11, liquid storage pot 12, first connecting pipe 13, second connecting pipe 14 and muffler, in an embodiment of the utility model, please refer to fig. 1 and fig. 2, liquid storage pot 12 is connected with the bottom of compressor main part 11, first connecting pipe 13 one end is connected in the outer wall of compressor main part 11, the other end is connected in the outer wall of liquid storage pot 12, in order to communicate the inside of compressor main part 11 with the inside of liquid storage pot 12; one end of the second connecting pipe 14 is communicated with the liquid storage tank 12, and the other end is bent to the upper part of the first connecting pipe 13 and extends upwards; the air return pipe is communicated with the liquid storage tank 12 through the second connecting pipe 14.
The air conditioner compressor 10 functions to compress and drive the refrigerant in the refrigerant circulation circuit, and pumps the refrigerant from the low-pressure region, compresses the refrigerant, and sends the compressed refrigerant to the high-pressure region for cooling and condensation. The liquid storage tank 12 is used for storing condensate of the condenser, meets the demand of load change of the evaporator on supply quantity, and is used as a liquid seal between high and low pressure sides of the system. The liquid storage tank 12 of the conventional rotor type compressor 10 is disposed at the side of the compressor body 11, resulting in a large overall size of the compressor 10, occupying a large space, and not suitable for an outdoor unit of an air conditioner having a small installation space.
The top of the liquid storage tank 12 is provided with an air return pipe, the bottom of the liquid storage tank is provided with a first connecting pipe 13 connected with the compressor 10, the top of the compressor main body 11 is provided with an exhaust pipe 111, when the compressor 10 works, low-temperature and low-pressure refrigerant enters the liquid storage tank 12 through the air return pipe, liquid refrigerant is stored in the liquid storage tank 12, gaseous refrigerant enters the compressor main body 11 through the first connecting pipe 13 and is compressed into high-temperature and high-pressure gaseous refrigerant in the compressor main body 11, and the high-temperature and high-pressure gaseous refrigerant is exhausted through the exhaust pipe 111. The return pipe is designed into a long pipeline which turns 180 degrees in order to avoid pipe breakage and excessive vibration, and occupies more space, and the pipeline is long and has higher material cost.
In this embodiment, referring to fig. 1 and 2, specifically, the axial direction of the compressor main body 11 is vertical, and the liquid storage tank 12 is connected to the bottom end of the compressor main body 11 along the axial direction of the compressor main body 11, so that two original tank bodies are changed into one tank body in the vertical direction, thereby reducing the overall size of the compressor 10, saving the installation space, and facilitating the miniaturization of the pipeline and the outdoor unit box. Meanwhile, since the center of the reservoir 12 is positioned on the same axis as the center of the compressor main body 11, vibration and noise generated during the use of the compressor 10 can be reduced.
One end of the first connecting pipe 13 is connected to the outer wall of the compressor main body 11, the other end of the first connecting pipe is connected to the outer wall of the liquid storage tank 12, the interior of the compressor main body 11 is communicated with the interior of the liquid storage tank 12, a low-temperature gaseous refrigerant enters the pump body of the compressor main body 11 through the first connecting pipe 13 to be compressed, and because the air inlet of the pump body is positioned in the compressor main body 11 and close to the bottom, the connecting position of the first connecting pipe 13 and the compressor main body 11 is positioned on the outer wall of the compressor main body 11 and close to the bottom of the compressor main body 11, so that a space above the first connecting pipe 13 can be used for the second connecting pipe 14 to run; in addition, the first connecting pipe 13 is disposed outside the compressor main body 11 and the liquid storage tank 12, which is beneficial to oil return and liquid return, has stronger reliability, and is also convenient for process manufacturing.

Because the first connecting pipe 13 is arranged outside the compressor main body 11 and the liquid storage tank 12 and protrudes out of the tank body of the compressor 10 in the radial direction of the compressor 10, the second connecting pipe 14 is bent above the first connecting pipe 13, and most of pipelines of the second connecting pipe 14 can be accommodated in the space above the first connecting pipe 13, so that the first connecting pipe 13 and the second connecting pipe 14 are approximately in a collinear state, the second connecting pipe 14 does not need to occupy the space protruding out of the tank body, and the space is further saved for the installation of the compressor 10. The return pipe is connected with the liquid storage tank 12 through the second connecting pipe 14, and compared with a pipeline with more bent positions of a conventional return pipe, the return pipe has the advantages that the pipeline can be reduced, the material is saved, the flow channel is smoother, the impact and resonance of pressure pulsation and an internal refrigerant on the pipeline are reduced, and therefore the refrigerant sound is relieved and reduced.
