The present invention relates to the technical field of air conditioners, and in particular, to an air conditioner indoor unit.

Background technique

During the long-term use of the air conditioner indoor unit, the air duct, wind wheel, water channel and other components are easily contaminated by dust accumulation, so the air conditioner needs to be disassembled and cleaned regularly. In the prior art, the base of the indoor unit is composed of an upper base and a lower base that are detachably connected. When disassembling and assembling the fan assembly of the air conditioner indoor unit, the lower base needs to be disassembled as a whole, and the disassembly and assembly steps are numerous, resulting in unnecessary trouble. .

SUMMARY OF THE INVENTION

The present invention aims to solve to a certain extent the technical problem in the prior art that the lower base assembly needs to be disassembled as a whole when disassembling the fan assembly.

In order to solve the above problems, the present invention provides an air conditioner indoor unit, comprising an upper base assembly, a fan assembly and a lower base assembly, the fan assembly is mounted on the lower base assembly, the upper base assembly and the lower base assembly Removably connected, and the lower base assembly is rotatably connected with the upper base assembly, the lower base assembly has a first position that facilitates the operation of the fan assembly and a second position that facilitates the removal of the fan assembly.

Therefore, by installing the fan assembly on the lower base assembly, the lower base assembly is rotatably connected with the upper base assembly, and when the fan assembly needs to be disassembled and cleaned, the lower base assembly can be lowered downward Rotate to allow the disassembly space of the fan assembly, avoid the overall disassembly of the lower base assembly and the upper base assembly, simplify the disassembly and assembly steps of the fan assembly, and realize the rapidity of the fan assembly. disassembly.
