[0043] The oil return structure of the prior art scroll compressor, when the high-temperature and high-pressure oil-gas mixed fluid discharged from the exhaust port 150 of the static disc row is output to the oil-gas separation structure, starts to perform oil-gas separation, at this time, the high-temperature and high-pressure refrigerant gas is discharged through the gas outlet of the compressor top cover 600, while the refrigeration oil is returned through the oil return channel due to the action of gravity and pressure difference, and lubricates the friction pair of the scroll compressor, thereby realizing the recycling of the refrigeration oil. This separation scheme may have the risk of high and low pressure side gas mixing, and the oil after throttling is still high-temperature oil, which has a certain influence on the performance and reliability of the compressor. Moreover, the refrigeration oil return channel path is single, and the refrigeration oil cannot be guided to return to the scroll everywhere, so that the refrigeration oil cannot fully lubricate the scroll, resulting in increased friction loss of the static scroll 100 and the dynamic scroll 004, and reduced reliability and service life of the electric scroll compressor.
[0044] In view of this, the designer provides a lubricating structure of an electric scroll compressor, the friction pair composed of the static scroll 100 and the dynamic scroll 004 has good lubricating effect, and the operation performance of the compressor is reliable.
[0045] Please refer to Figure 1 and Figure 2The embodiment provides a lubricating structure of an electric scroll compressor, which comprises a static scroll 100, the static scroll 100 comprising a disc body 110 and a scroll plate 120 connected to each other, an oil feeding channel 130 being arranged on the disc body 110, one end of the oil feeding channel 130 being used for introducing refrigerant oil, the other end of the oil feeding channel 130 being located in an area surrounded by the scroll plate 120, and the oil feeding channel 130 being used for feeding the refrigerant oil into a compression cavity formed by the static scroll 100 and a dynamic scroll 004.
[0046] As described above, the working mode of the lubricating structure of the electric scroll compressor provided by the embodiment is as follows:
[0047] By arranging the oil feeding channel 130 on the disc body 110 of the static scroll 100, the high-pressure oil-gas mixture discharged from the exhaust port 150 of the electric scroll compressor enters the external oil-gas separator 200, the separated refrigerant oil can return to the static scroll 100 from the oil feeding channel 130, and the oil outlet is located at the scroll plate 120 of the static scroll 100, so that the refrigerant oil is quickly contacted with the scroll plate 120, the scroll plate 120 is lubricated, and the lubricating effect is good. The compressed gas is guided out of the static scroll 100, and after being separated by the external oil-gas separator 200, the refrigerant oil returns to the static scroll 100, so that the gas is not easy to be mixed, and the operation is safe and reliable.

The heat exchanger 500 cooperates with the oil feeding pipe 300, the refrigerant in the heat exchanger 500 can exchange heat with the refrigerant oil in the oil feeding pipe 300, so that the temperature of the refrigerant oil is reduced. The refrigerant oil after being cooled returns to the static scroll 100, the lubricating effect is good, and the operating performance of the compressor is not easy to be affected by high temperature.
[0050] Furthermore, the high-temperature, high-pressure oil-gas mixture is drawn from the static scroll 100 and separated by an external oil-gas separator 200, minimizing the risk of cross-flow. Furthermore, the refrigerant oil flows through the oil pipeline 300, facilitating heat exchange with the heat exchanger 500 and facilitating temperature control of the refrigerant oil. Furthermore, an oil injection control valve 310 is installed on the oil pipeline 300 to control the timing and amount of oil injection.
[0051] It should be understood that both the oil-gas separator 200 and the heat exchanger 500 can employ conventionally known structures. To avoid redundancy, detailed descriptions are omitted in this embodiment. The oil-gas separator 200 is capable of separating the high-temperature, high-pressure oil-gas mixture. The separated gaseous refrigerant participates in the air conditioning refrigeration cycle, while the separated refrigeration oil returns to the compressor for recycling. The heat exchanger 500 can be a plate-type heat exchanger 500 or a tubular-type heat exchanger 500, for example.

One end of the connecting hole section 131 is located on the side of the disk body 110 away from the scroll plate 120 and is used to plug in the oil injection pipe 400, and the other end is simultaneously connected to the two oil delivery hole sections 132. The axes of the two oil delivery hole segments 132 form an angle, which can be set as needed to ensure that the oil delivery hole segments 132 communicate with the connecting hole segment 131 and the corresponding oil injection hole segment 133. Furthermore, the two oil delivery hole segments 132 intersect and communicate at the intersection, while the connecting hole segment 131 communicates with the intersection of the two oil delivery hole segments 132.

By communicating the oil injection hole section 133 with the second compression cavity 002 after the suction is closed, in this state, the compression cavity formed by the cooperation of the dynamic volute 004 and the static volute 100 has completed the suction, and the refrigeration oil entering the second compression cavity 002 from the oil injection hole section 133 will not affect the volumetric efficiency and will not easily affect the normal operation of the compressor.

The oil injection pipe 400 can be directly inserted into the connecting hole section 131, thereby facilitating the installation of the oil injection pipe 400. It should be noted that, when the number of the oil injection hole sections 133 is multiple, the ports of all the oil injection hole sections 133 can correspond to the region of the second compression cavity 002 formed after the suction of the compressor is closed.
[0055] In addition, one end of the oil supply hole section 132 is communicated with the oil injection hole section 133, and the other end is located on the outer circumferential surface of the disc body 110, so that, when the oil supply hole section 132 is processed, the drilling can be performed from the outer circumferential surface of the disc body 110, thereby facilitating the operation.
