Exhaust components, compressors and air conditioners

Abstract

The application provides an exhaust assembly, a compressor and an air conditioner. The exhaust assembly at least includes a fixed seat; an exhaust valve plate, fixed on the fixed seat, and elastically covers the exhaust port; a lift piece, one end of which is against the exhaust valve plate, and the lift piece can The movement direction of the exhaust valve plate is movably arranged on the fixed seat. The lift piece can be moved against the exhaust valve plate to ensure that the lift of the exhaust valve plate is variable, adapting to different working conditions, and reducing the collision noise between the exhaust valve plate and the lift piece.

Description

technical field [0001] The application belongs to the technical field of compressors, and in particular relates to an exhaust assembly, a compressor and an air conditioner. Background technique [0002] As we all know, the development direction of compressors for home appliances tends to be miniaturized, high-efficiency, and low-noise. The requirements for the low-voltage start-up ability of refrigerator compressors are gradually increasing, and the miniaturization, low-voltage start-up ability and low-noise characteristics have obvious market Competitive advantages and good user experience, as people's pursuit of a better life has become the main contradiction in society, higher requirements are put forward for the space, energy saving, noise reduction, and high efficiency of home appliances, and products with the above characteristics are becoming more and more popular among consumers. reader's favorite.

Problems solved by technology

[0003] At present, the fully enclosed reciprocating compressor cylinder head has various structures in the market. One is that the lift limit of the exhaust valve plate is not set on the cylinder head, and the other is that the lift limit of the exhaust valve plate is set on the cylinder head. like figure 1 As shown, there are the following limitations and problems in the existing structure in which the exhaust valve plate 3 is arranged on the cylinder head 1: (1) the lift height of the traditional exhaust valve plate 3 is generally a fixed value, and the lift of the valve plate cannot According to the change of working condition load or the change of operating frequency, corresponding adjustments are made to achieve the best performance state of the compressor operating condition and affect the performance of the compressor; (2) The existing lift part 2 is integrally cast in the cylinder head structure , is made of metal, the valve plate is directly slapped on the lift limit structure, and the impact noise is directly transmitted, which is not conducive to the low-noise design of the compressor. (3) The traditional valve slap lift parts 2 are between metal and metal The hard contact of the fixed lift part 2 is not buffered and unloaded, resulting in poor reliability of the valve plate, requiring high strength requirements for the valve plate steel, and at the same time, the cost is high
