Scroll compressor and air conditioner

Abstract

The invention belongs to the technical field of compressors, and discloses a scroll compressor and an air conditioner, the scroll compressor comprises a crankshaft, a crankshaft oil pool and an oil passage, and the crankshaft is provided with an oil guide structure; when the crankshaft rotates to one end of the oil guiding structure to be communicated with the crankshaft oil pool and the other end of the oil guiding structure to be communicated with the oil passing channel, the oil guiding structure guides out lubricating oil in the crankshaft oil pool through the oil passing channel; the operation frequency of the scroll compressor is in positive correlation with the connection frequency of the oil guide structure, the crankshaft oil pool and the oil passing channel. The crankshaft oil pool and the oil passing channel are communicated once by the oil guiding structure every time the crankshaft rotates by a circle, and in the process, along with the improvement of the operation frequency of the compressor, the number of times of communicating the crankshaft oil pool and the oil passing channel by the oil guiding structure is increased within the same time, and the oil supply amount is correspondingly increased; otherwise, the oil supply amount is reduced when the times are reduced; therefore, the oil quantity requirements of the compressor under different frequencies can be effectively met, and the oil quantity is related to the operation frequency.

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 oil supply to the back pressure chamber of existing compressors generally adopts the oil supply through the oil tank. The principle is: there is a pressure difference between the back pressure chamber and the oil pool, and the oil tank is set The oil tank enters the back pressure chamber in the low pressure area from the high pressure area. The amount of oil in this oil supply method is only related to the pressure difference, which cannot meet the different oil volume requirements of the compressor at different frequencies.

Problems solved by technology

[0003] In view of this, the present invention provides a scroll compressor and an air conditioner. The oil introduction structure is arranged on the crankshaft, and the connection and disconnection of the oil supply are realized by the rotation of the crankshaft, so that the operating frequency of the compressor and the frequency of the oil supply are positive. Relevant, solve the problem of mismatching oil supply and frequency in traditional technology
