Embodiment Construction

[0051] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0052] like figure 1 As shown, it is a compressor structure in the prior art, which mainly includes a compressor upper cover, a stationary disk, a moving disk and a compressor driving support structure. An exhaust cavity and an oil separation cavity are formed between the compressor stationary disk and the upper cover. The oil storage chamber is relatively arranged be...

Abstract

The invention provides an oil return structure of a compressor, the compressor and an air conditioner, the oil return structure of the compressor comprises a static disc and a cover body, the end face, facing the cover body, of the static disc is provided with a first protrusion protruding towards the cover body, and / or the end face, facing the static disc, of the cover body is provided with a second protrusion protruding towards the static disc; the first protrusion is matched with the cover body, or the second protrusion is matched with the static disc, or the first protrusion is matched with the second protrusion so that a cavity used for exhausting and / or separating oil can be formed on the inner periphery of the protrusion, and the inner periphery of the cover body and the outer periphery of the protrusion jointly define an oil storage cavity used for storing oil. The oil storage cavity is located on the radial outer side of the exhaust and / or oil distribution cavity. Through the effective design on the static disc and the cover body, the space of the static disc and the cover body is effectively utilized, so that the oil storage cavity is effectively formed on the basis of not increasing the axial and radial sizes of the compressor, and the weight and the size of the compressor are not increased while the oil storage volume of lubricating oil is increased.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to an oil return structure of a compressor, a compressor and an air conditioner. Background technique [0002] The aluminum alloy scroll compressor for vehicles has no stable oil pool inside the compressor for the internal pump oil system of the compressor to mechanically supply oil to the lubricating parts, but relies on the suction refrigerant of the compressor to carry the lubricating oil, and the exhaust is centrifugally separated for refrigeration. After the lubricant and lubricating oil are removed, the lubricating oil shall be throttled and returned to the lubricating oil. Therefore, the oil return efficiency of the centrifugal separation of the exhaust gas is critical to the performance and reliability of the compressor. The existing centrifugal separation structure is very mature, and the simple centrifugal separation structure has high separation efficiency, which can...
