The present disclosure relates to the field of air conditioning technology, and particularly to an air conditioning indoor unit that can be disassembled and cleaned.

BACKGROUND OF THE INVENTION As living standards improve, people's demands for living environments become higher and higher, and air conditioners are widely used to adjust room comfort by adjusting environmental temperature and/or humidity.

After a conventional air mixer has been used for a certain period of time, a large amount of dust accumulates in the internal air duct system and other parts, making it easy for harmful bacteria to grow, making the air mixer a source of secondary pollution, which poses a threat to human health. cause harm. BACKGROUND ART Conventional air blenders have complicated assembly relationships between parts and cannot be disassembled and cleaned by users themselves, so air blenders that are easy to disassemble and clean are currently becoming more popular. When the indoor unit operates, the fan continues to rotate, and after the air passes through the air path member and exchanges heat with the evaporation member, it is blown out from the blowout member. Dust and bacteria in the air tend to accumulate on air duct members,
As it is, it affects the quality of the blown air and further affects the health of the user. Therefore, in the conventional air conditioner that can be disassembled and cleaned, the air passage member is provided to be removable from the casing and base of the indoor unit, thereby making it easy to clean the air passage member. However, conventional removable air duct members are generally connected to the base body and casing via several screws, so when removing them, all screws on the air duct member must be removed in order. There is a need. Furthermore, when removing, it is necessary to store the dimensions and mounting positions of each screw without confusing them so that they can be reassembled. This causes great inconvenience to the cleaning process and results in a poor user experience. Furthermore, if the screws are assembled several times, the screw holes will collapse and the installation of the air path member will become unstable.
