Description

Technical Field

[0001] The utility model relates to the field of air conditioning, in particular to a vibration reduction structure of an outdoor unit of an air conditioning. Background Art

[0002] The outdoor unit of a household air conditioner is conventionally installed by welding the outdoor unit bottom plate and the mounting bracket together. Long-distance transportation, handling, unreasonable installation and other factors can easily cause the installed air conditioner to produce resonant vibrations close to the natural frequency of the building. When resonance occurs, the low-frequency vibration noise is transmitted to the mounting bracket through the outdoor unit bottom plate, and then transmitted to the indoor by the mounting bracket, seriously affecting the user's life. The current solution is to use bolts to fix the outdoor unit bottom plate and the mounting bracket, and transmit vibration through the screw, which can play a certain vibration reduction role. However, there is still metal connection between the outdoor unit bottom plate and the mounting bracket, and the vibration energy can only be partially diluted. A large amount of vibration energy can still be transmitted to the indoor. How to effectively reduce the vibration of the air conditioner outdoor unit has become a difficult problem.
