Embodiment 1

[0034] Such as image 3 As shown, the present invention is a compressor, including a pump body 12, a motor 2, a casing 3, and a liquid accumulator 4 and the like.

[0035] The pump body 12 can be a bottom exhaust structure or an upper and lower exhaust structure. The lower part of the pump body 12 is equipped with a heat-insulating and sound-absorbing cover. The heat-insulating and sound-absorbing cover has a structure of more than two layers, and an oil storage and heat-insulating space 11 is formed between each layer of sound-absorbing covers. The outline size of the sound-absorbing cover located on the outer layer is larger than that of the sound-absorbing cover located on the inner layer, and covers the sound-absorbing cover located on the inner layer. For example, in this embodiment, the heat-insulating and sound-absorbing cover has a two-layer structure, including an inner layer of sound-absorbing cover 9 and an outer layer of sound-absorbing cover 10 . The outline siz...

Embodiment 2

[0044] Such as Figure 10 As shown, the outline size of the outer layer sound-absorbing cover 10 in the present embodiment is smaller than the inner layer sound-absorbing cover 9, after installation, as Figure 11A As shown, the outer sound-absorbing cover 10 partially covers the bottom of the inner-layer sound-absorbing cover 9 . The outer sound-absorbing cover 10 has a bulging portion 27, which covers the flat portion 25 of the inner sound-absorbing cover 9, and is correspondingly located below the low-temperature and low-pressure area of ​​the pump body. The outer sound-absorbing cover 10 is provided with bolt holes 28, and is fixed to the inner-layer sound-absorbing cover 9 by bolts. Such as Figure 11B As shown, an oil storage and heat insulation space 11 is formed between the bulging part 27 and the flat part 25, and the refrigerating machine oil 5 enters the oil storage and heat insulation space 11 through the matching gap between the inner and outer sound-absorbing c...

Abstract

The invention discloses a compressor. The compressor comprises a pump body, a motor, a shell and a liquid storage device, wherein an insulation silencing cover is installed on the lower part of the pump body, the insulation silencing cover is of a more-than-two-layer structure, and an oil storage insulation space is formed between every two adjacent layers of silencing covers. By adopting the insulation silencing cover structure, the silencing cover is simple to machine, low in production cost and easy to popularize and use compared with the existing insulation lower bearing; the oil storage insulation space is established through multiple layers of silencing covers, the mobility of the oil entering the oil storage insulation space is greatly reduced, a relatively still oil layer is formed, an external high-temperature freezing engine oil is separated from the lower bearing, the heat, transferred to the external environment, of the high-temperature coolant gas can be reduced, the energy loss of the compressor can be reduced, the heat expansion of the coolant gas inside the pump body can be prevented, the volume efficiency of the compressor can be improved, and the energy efficiency of the compressor can be improved.

Description

technical field [0001] The invention relates to the field of compressors, in particular to a compressor with a heat-insulating and sound-absorbing cover. Background technique [0002] High-efficiency rotary compressors for current air conditioners such as figure 1 As shown, it is at least composed of a pump body 1, a motor 2, a casing 3, a liquid reservoir 4 and related accessories. Refrigerator oil 5 is stored in the lower part of the casing 3 . The pump body 1 has an upper and lower exhaust structure or a lower exhaust structure, and is fixed below the inside of the housing 3 and is directly soaked in the refrigerating machine oil 5 at the bottom of the housing 3 . The lower part of the pump body 1 is generally equipped with an ordinary lower bearing 6 and a single-layer lower sound-absorbing cover 7 . [0003] During the working process of the compressor with the above structure, the refrigerant gas is compressed and its temperature rises. For the ordinary pump body 1...
