Air conditioner indoor unit and split-type air conditioner

The vibration reduction system is segmented into two stages: a first-stage elastic vibration reduction structure between the compressor and a partition, and a second-stage elastic vibration reduction structure between the partition and the chassis. This segmentation allows progressive attenuation of vibrations at different levels, effectively reducing noise while maintaining the compressor in the indoor unit.

A partition is introduced as an intermediary element between the two-stage vibration reduction structures. The partition acts as a mediator that receives vibrations from the first-stage reduction structure and transmits them to the second-stage reduction structure, enabling a more effective progressive damping of compressor vibrations and noise.

The vibration reduction system is divided into two distinct stages with different structures and functions. The first-stage structure handles initial vibration isolation, while the second-stage structure provides additional damping through the partition interface. This segmentation achieves superior noise reduction without creating an overly complex monolithic structure.

The vibration reduction system employs composite elastic structures with different material properties at each stage. The first-stage and second-stage elastic vibration reduction structures use different elastic materials and configurations, creating a composite system that leverages the advantages of each material to achieve effective noise reduction across different frequency ranges.
