Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to a compressor noise reduction device. Background Technology

[0002] The compressor inside household appliances can easily generate strong and slow-dissipating noise due to problems such as mechanical friction, loose parts, liquid compression, system overload, improper installation, and poor air intake or exhaust. This can cause great annoyance to users and affect their user experience. The negative impact of this noise is even more obvious for some household appliances installed indoors.

[0003] In the prior art, such as Chinese patent CN206280217U, a compressor noise reduction structure is proposed. This structure reduces noise at its source by setting a buffer cotton layer at the bottom of the compressor and setting sound-absorbing cotton layers on both sides and top to block the transmission of internal compressor noise outward.

[0004] However, the existing technology has the following drawbacks: 1. The sound-absorbing cotton layer directly wraps the compressor and the gas-liquid separator; since both the gas-liquid separator and the compressor body generate noise, it is equivalent to placing two noise sources together in the sealed cavity formed by the sound-absorbing cotton layer, which may cause sound wave interference and noise superposition; 2. The sound-absorbing cotton layers are fixedly connected, which makes it difficult to disassemble when the compressor needs to be repaired, increasing material costs.

[0005] Therefore, there is an urgent need to design a compressor noise reduction device that can effectively solve the problems of noise superposition and inconvenient disassembly. Utility Model Content

[0057] Compared with the prior art, the technical effects achieved by this utility model are as follows:

[0058] 1) By installing sound-absorbing sponges on the outside of the compressor body and the gas-liquid separator, the sound wave interference and noise superposition between the two noise sources can be reduced, thereby improving the noise reduction effect;

[0059] 2) The first layer of sound-absorbing foam mainly absorbs high-frequency noise, while the second layer targets low-frequency noise. This design allows the system to more effectively absorb noise of different frequencies, achieving more comprehensive noise reduction; PU wave cotton is placed inside the sealed shell to further absorb noise generated by the compressor operation, enhancing the noise reduction effect.

[0060] 3) Use Velcro to connect the various parts of the sound-absorbing foam, so that it can be easily disassembled when needed without additional tools, which improves the convenience of maintenance;

[0061] 4) The sealed shell sidewalls are bent in multiple places to form a structure that encloses the compressor. This design helps to refract or reflect some of the noise, so that the noise gradually weakens during the transmission process, thus achieving the purpose of noise reduction.

[0062] 5) The sealed housing is divided into 5 parts, which are fixed with screws. This modular design allows for quick disassembly and assembly when the compressor needs to be repaired or replaced, saving time and labor.
