Embodiment Construction
[0031] see in conjunction Figure 1 to Figure 6 As shown, according to an embodiment of the present application, a connecting rod assembly includes:
[0032] connecting rod 1, including a first end 11 connected to the eccentric shaft 21 of the crankshaft 2;
[0033] The first end 11 includes a ring body 111 and a top cover 113. An oil storage space is arranged inside the ring body 111. The top cover 113 is arranged on one end of the ring body 111 and covers at least part of the oil storage space. oil space; the ring body 111 is sheathed on the outer periphery of the eccentric shaft 21; the first end 11 is provided with an oil throwing hole 112 communicating with the oil storage space; when the crankshaft 2 rotates, the The oil on the crankshaft 2 is thrown out through the oil throwing hole 112 .
[0034] Since the conventional crankshaft 2 is provided with an oil supply hole, the oil at the bottom is delivered to the top of the crankshaft 2 for lubricating the first end 11 a...

The invention provides a connecting rod assembly, a piston type compression mechanism and a refrigerator. The piston type compression mechanism comprises a connecting rod, wherein the connecting rod comprises a first end connected with an eccentric shaft of a crankshaft; the first end comprises a ring body and a top cover, an oil storage space is formed in the ring body, and the top cover is arranged at one end of the ring body and covers at least part of the oil storage space; the ring body is arranged on the periphery of the eccentric shaft in a sleeving manner; an oil throwing hole communicating with the oil storage space is formed in the first end; and when the crankshaft rotates, oil on the crankshaft is thrown out through the oil throwing hole. The first end of the connecting rod is arranged to be of a cover structure composed of the ring body and the top cover, the eccentric shaft is covered, the upper end of the first end is not of a traditional open structure, the oil throwing hole is formed in the first end, oil brought by the crankshaft rotating at a high speed can only be thrown out from the oil throwing hole, and therefore the oil particle diffusion range is greatly reduced, and the oil content in the mixed gas discharged by a compressor can be obviously reduced.
Description
technical field [0001] The application belongs to the technical field of refrigerators, and in particular relates to a connecting rod assembly, a piston compression mechanism and a refrigerator. Background technique [0002] Piston compressors are often used in household refrigerators. With the improvement of energy saving requirements, customers have higher and higher requirements for refrigerator energy efficiency. The oil discharge rate of the compressor refers to the mass ratio of the refrigerant oil in the oil-air mixture (the mixture of refrigerant and refrigeration oil) discharged from the compressor per unit time. If the oil discharge rate of the compressor is too high, it will affect the heat exchange of the refrigerator system Efficiency further affects energy efficiency, and reducing the oil discharge rate of compressors is a difficult point that the industry is currently concerned about. [0003] Since the gaseous refrigerant will flow in the entire compressor c...
