Abstract

The invention discloses a compressor noise reduction device. The device comprises a sound-absorbing cotton and a hoop frame; the hoop frame is arranged on the outer side of a compressor shell, the sound-absorbing cotton wraps the outer side of the hoop frame, an air gap is arranged between the sound-absorbing cotton and the compressor body, the air gap is arranged between the sound-absorbing cotton and the compressor body, the phenomenon that the sound-absorbing cotton makes direct contact with the compressor shell, the sound-absorbing cotton is gradually aged and makes contact with the compressor shell, and abnormal sounds are generated is avoided, the service life of the sound-absorbing cotton is prolonged, the air gap between the hoop frame and the compressor body is beneficial to air flowing, the temperature of the compressor body wrapped by the sound-absorbing cotton can be effectively reduced, it is ensured that a compressor motor works at the normal temperature, the noise reduction effect of the sound-absorbing cotton can be ensured, and safety is improved.

Description

technical field [0001] The invention relates to the technical field of noise reduction structures, in particular to a compressor noise reduction device and a compressor. Background technique [0002] With the progress of society and the improvement of people's living standards, heat exchange equipment such as air conditioners are more and more widely used in daily life, which increases the comfort of people's lives. The outdoor unit of the air conditioner will generate noise during operation, and the noise mainly comes from the fan and the compressor. The noise control of the fan is mainly realized by improving its blade shape, and the main noise reduction method of the compressor is realized by preventing the propagation of sound waves. [0003] At present, in the prior art, the noise reduction method of the compressor is to tightly cover a layer of sound-absorbing cotton on the surface of the compressor, and the sound-absorbing cotton is composed of a high-frequency sound-...
