Abstract

The invention relates to the technical field of air conditioners, and discloses an outdoor air conditioner. The outdoor air conditioner comprises a shell and a compressor arranged in the shell and further comprises a sound insulation cover arranged on the shell, a sound insulation cap connected to the sound insulation cover; a containing cavity is formed among the sound insulation cover, the soundinsulation cap and the shell; the compressor is arranged in the containing cavity; the sound insulation cover and the sound insulation cap comprise an air resonant cavity used for absorbing sound waves generated when the compressor works and a silencing unit used for limiting the sound waves from being transmitted to the exterior of the sound insulation cover from the interior of the containing cavity. The low-frequency noise is effectively absorbed, the physical and psychological health of a user is protected, and the user experience when the air conditioner is used is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an outdoor air conditioner. Background technique [0002] Noise pollution is already the first of the seven major public hazards in the world, and low-frequency noise is a chronic damage to the human body, which cannot be ignored. Because low-frequency noise can directly reach people's ear bones, it can also cause people's sympathetic nervousness, tachycardia, elevated blood pressure, and endocrine disorders. People are forced to accept this kind of noise, easily annoyed, agitated, irritable, and even lose their minds. If long-term harassed by low-frequency noise, it is easy to cause various neurosis such as neurasthenia, insomnia, headache, and even affect the fetus in the pregnant woman's womb. Many people hold the attitude of forbearance and forbearance, which is very incorrect. [0003] At present, the air conditioner compressor sound insulation cover generally ad...
