Abstract

The invention discloses a sound insulation structure, an air conditioner outdoor unit and an air conditioner. The sound insulation structure comprises a body and protruding structures, and the body is in a sheet shape and is provided with a first surface; and the multiple protruding structures are arranged on the first surface at intervals, a cavity is formed between each protruding structure and the body, the multiple cavities are sealed in an airtight manner, each protruding structure is provided with a vibration surface far away from the first surface, and the vibration surfaces are used for generating vibration during sound wave propagation. The sound insulation structure is used for wrapping the periphery of a sound source such as a compressor, when sound waves generated by the sound source pass through the protruding structures, the vibration surfaces play a role in vibration reduction and sound absorption through vibration, the cavities have a certain sound insulation function, so that two noise reduction modes of sound insulation and sound absorption are organically combined, medium-high frequency noise of the sound source such as the compressor can be effectively reduced, and pollution of the noise to the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a sound insulation structure, an air conditioner outdoor unit and an air conditioner. Background technique [0002] There is a compressor installed in the outdoor unit of the air conditioner. Due to the force such as the electromagnetic torque of the compressor motor and the gas resistance torque, the compressor will generate medium and high frequency electromagnetic noise, mechanical noise, aerodynamic noise, etc., causing noise pollution to the environment around the compressor. . In the prior art, the compressor is usually wrapped with felt fiber sound-absorbing material or rubber-like sound-insulating material or a composite of the two materials for sound-insulating and noise-reducing treatment. However, the existing sound insulation or sound absorption materials are not effective in reducing the high-frequency noise of the compressor, and it is difficult to meet th...
