Embodiment 1

[0051] This embodiment provides a scroll compressor, such as figure 1 As shown, it includes a crankshaft 100 and an oil control assembly 200, the oil control assembly 200 is arranged at the lower end of the crankshaft 100, and the oil control assembly 200 and the middle oil hole of the crankshaft 100 form an oil passage 300; the operating frequency of the scroll compressor is related to the oil passage 300 Opening is positively related.

[0052] In this way, with the above structure, the opening of the oil passage 300 is positively correlated with the operating frequency of the compressor, and the opening of the oil passage 300 directly affects the oil supply. Therefore, this embodiment realizes the relationship between the oil supply and the operation of the compressor. Frequency matching avoids the problem of dry grinding caused by insufficient oil supply, and also avoids the problem of reduced refrigeration capacity caused by excessive lubricating oil.

[0053] Moreover, s...

Abstract

The invention discloses a scroll compressor and an air conditioner, and belongs to the technical field of compressors. The scroll compressor comprises a crankshaft and an oil control assembly, the oil control assembly is arranged at the lower end of the crankshaft, and an oil passing channel is formed by the oil control assembly and a middle oil hole of the crankshaft; the operation frequency of the scroll compressor is in positive correlation with the opening degree of the oil passing channel. According to the scroll compressor, the oil control assembly is arranged at the lower end of the crankshaft, the oil passing channel is formed by the oil control assembly and the middle oil hole of the crankshaft, and when the operation frequency of the scroll compressor changes, the opening degree of the oil passing channel changes accordingly; in this way, the opening degree of the oil passing channel is matched with the operation frequency of the compressor, the oil supply amount is directly influenced by the opening degree of the oil passing channel, therefore, the oil supply amount is matched with the operation frequency of the compressor, the problem of dry grinding caused by insufficient oil supply is solved, and meanwhile the problem that the refrigerating capacity is reduced due to the fact that the lubricating oil amount is too large is solved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a scroll compressor and an air conditioner. Background technique [0002] Scroll compressors are widely used in the field of air conditioning due to their high working efficiency. In order to ensure the stable and reliable operation of scroll compressors, the friction pairs between various parts must be effectively lubricated. The scroll compressor uses an oil pump to supply oil. Driven by the motor, the crankshaft drives the oil pump to rotate and absorb oil, and the lubricating oil (refrigerating machine oil) moves upward along the oil hole in the middle of the crankshaft. The oil pump and the compressor pump body are in a coaxial structure. The rotation of the crankshaft drives the compressor pump body and the oil pump to rotate. The compressor speed is the same as the oil pump speed. When selecting the type, in order to meet the oil supply volume when the compressor is r...
