Problems solved by technology

However, this type of structure has a limited effect on reducing the oil content of the compressor, which often leads to insufficient lubrication of the pump body structure of the compressor due to the high oil content in the air conditioning system. , the work done by the oil cycle increases, and the energy efficiency of the air conditioner is low

Embodiment Construction

[0028] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0029] Such as Figure 1 to Figure 7 As shown, according to the embodiment of the present invention, the oil retaining device includes a base plate 11 and a surrounding plate 12 surrounding the periphery of the base plate 11. The cross-sectional area of ​​the surrounding plate 12 gradually increases along the direction away from the base plate 11. The surrounding plate 12 A first air hole 13 communicating with the inside and outside of the enclosure 12 is provided on the top.

[0030] Along the direction away from the base plate 11, the cross-sectional area surrounded by the surrounding plate 12 gradually increases to form a tapered structure. Using this tapered structure, a first air hole 13 is provided on the surrounding plate 12. Due to the fluency of the tapered structure, When the compressor is running, a large amount of oil-air mixture passes throug...

Abstract

The invention provides an oil retaining device and a compressor comprising the same. The oil retaining device provided by the invention comprises a base plate and a surrounding plate which is arranged in a manner of surrounding the periphery of the base plate; the cross section area surrounded by the surrounding plate in a direction far away from the base plate is gradually increased; the surrounding plate is provided with a first ventilating hole which communicates with the inside and outside of the surrounding plate. The oil retaining device is good in oil and gas separation effect.

Description

technical field [0001] The invention relates to the field of air conditioning equipment, in particular to an oil retaining device and a compressor having the same. Background technique [0002] In the existing rotary compressor technology, the amount of oil discharged has a significant impact on the performance of the air conditioning system. Various compressor manufacturers have been committed to reducing the amount of oil discharged by the compressor. The oil output of the compressor is large, and there will be more lubricating oil attached to the pipeline of the air conditioning system, which will cause poor heat exchange between the pipeline and the outside world, resulting in a decrease in the performance of the air conditioner, and may also cause oil blockage in the system pipeline. In addition, it will also reduce the amount of oil used for frictional lubrication of various parts in the compressor, resulting in increased friction loss, and even dry friction, which wi...
