[0030] Fly disc body 216 is fixedly connected with rotating shaft body 209, and eccentric wheel 215 is movably connected in the inside of cylinder 212.
[0031] Further explanation is needed:
[0032] As the key part of refrigerant compression, the refrigerant entering through the inlet hole 204 will be compressed. It uses the power generated by the stator 211 and the rotor 210 to drive the rotation of the shaft body 209, and then converts the rotary motion into the required compression motion through the eccentric wheel 215 and other components, realizing the compression of the refrigerant and providing the necessary pressure for the entire refrigeration cycle, driving the refrigerant to flow in the system.
[0033] The inlet hole 204 and the outlet hole 207 are responsible for the suction and discharge of the refrigerant respectively, controlling the flow direction of the refrigerant. The double pipe 205 serves as a connecting channel to ensure smooth flow of the refrigerant between different components. At the same time, the cold gas preparation cavity and the compressed gas release cavity are composed of the compressor lower cover 203, the shell 202, the cylinder 212 and other components, providing a specific space for the gathering, compression and transition of the refrigerant, ensuring that the refrigerant can orderly complete the conversion and flow in different states.
[0034] The compressor upper cover 201, the shell 202 and the lower cover 203 provide stable structural support for the internal components, enabling them to work stably. At the same time, it also plays a role in protecting the internal precision components, avoiding damage to the internal parts by external factors. The one-way valve 213 ensures that the refrigerant can only flow in the predetermined direction, preventing backflow and ensuring the stable operation of the refrigeration system. The rotating seal and lubricating oil in the flywheel housing 214 provide sealing and lubrication for the moving parts such as the flywheel body 216, reducing friction and wear, further ensuring the stability and reliability of the system operation.
[0035] The working principle of the above embodiment is:
[0036] First, the refrigerant is stored in the liquid storage tank 1. When the compressor starts to work, in the compressor assembly 2, because the shaft body 209 and its connected components have not yet produced compression effect on the refrigerant, the refrigerant in the liquid storage tank 1 will enter the compressor assembly 2 through the inlet hole 204 under the action of pressure difference. At this time, the cold gas preparation cavity composed of the inlet hole 204, the compressor shell 202, the compressor lower cover 203 and the cylinder 212 provides a temporary storage space for the entering refrigerant.
[0037] Secondly, the stator 211 in the compressor assembly 2 generates a rotating magnetic field after being connected to the power supply, which makes the rotor 210 rotate. The rotor 210 drives the rotation of the shaft body 209, and the shaft body 209 is connected with the eccentric wheel 215 and the flying disc body 216 and other components. The eccentric wheel 215 will convert the rotary motion of the shaft body 209 into some form of reciprocating or other form of motion, which may be piston motion. Although not explicitly mentioned, it is generally present in compressors, and the refrigerant is compressed in the cylinder 212.
[0038] During the compression process, the cold air composed of the compressor upper cover 201, the compressor shell 202 and the partition plate 206 passes through the cavity, and the compressed gas release cavity composed of the compressor shell 202, the partition plate 206 and the cylinder 212 will guide the flow path of the refrigerant, ensuring that the refrigerant is compressed in an orderly manner. The one-way valve 213 ensures that the refrigerant can only flow in the compression direction, preventing backflow.
[0039] Then, after compression, the refrigerant becomes high-temperature and high-pressure gas, and its pressure and temperature are greatly increased. These high-temperature and high-pressure gases are discharged from the compressor assembly 2 through the gas outlet hole 207 on one side of the compressor shell 202. At this time, the high-temperature gas in the compressed gas release cavity has completed the transition from a low-temperature and low-pressure state to a high-temperature and high-pressure state, and is discharged from the gas outlet hole 207.
[0040] Next, the high-temperature and high-pressure gas discharged from the gas outlet hole 207 enters the condenser 3 through the pipeline. In the condenser 3, the high-temperature and high-pressure gas dissipates heat to the external environment, and its temperature decreases, gradually condensing into liquid refrigerant.
[0041] Finally, the liquid refrigerant cooled by the condenser 3 will return to the liquid storage tank 1, or through other pipeline systems, return to the gas inlet of the compressor assembly 2 again, and start the next refrigeration cycle.
[0042] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, principle of the present application should be covered within the protection scope of the present application.
