Description

Air conditioner outdoor unit Technical Field The utility model belongs to the technical field of air conditioning equipment, and particularly relates to an air conditioning outdoor unit. Background A mounting foot of the bottom of the compressor in the air conditioner outdoor unit is connected to a bottom plate of an outer shell through a vibration reduction block, and when the compressor is in operation, vibration of the compressor can be transmitted to sheet metal parts such as the outer shell through bolts on the mounting foot, and the sheet metal parts radiate noise outwards during vibration, so that comfort and mental health of a user are affected. The common noise reduction measure is to arrange a sound-proof cover outside the compressor, and alleviate the transmission of the compressor noise by improving the sound insulation amount of the sound-proof cover, but the sound-proof mode has poor effect on the low-frequency noise caused by vibration, because the wavelength of the low-frequency noise is longer, diffraction is easy to generate, the penetrating power is strong, the sound-proof cover is difficult to isolate, the outward transmission of the vibration noise can be only partially reduced, and the generation and transmission of the vibration cannot be fundamentally reduced. Disclosure of utility model The utility model aims to provide an air conditioner outdoor unit, which solves the problems that in the prior art, noise is formed by vibration in the working process of a compressor, sound insulation and noise reduction structures such as a sound-proof cover and the like can only reduce partial noise transmission and can not reduce the vibration of the compressor from the source.
