Wall-Mounted AC Fan Assembly for Easy Cleaning and Motor Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted air conditioners have a fixed fan assembly that makes cleaning and maintenance difficult due to the lack of disassembly options, leading to dust accumulation and inconvenient motor replacement.
Innovation Solution
The indoor unit design features a housing with a removable front frame and chassis, allowing the fan assembly to be exposed and easily disconnected for cleaning and maintenance, utilizing snap-fit buckles and rotating shafts for secure and stable mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the fan assembly is fixed non-removably on the chassis, then the structural stability is improved, but the ease of cleaning and maintenance deteriorates
Solution Approach 1:
The fan assembly is segmented from the housing structure, allowing it to be removably connected to the front frame and chassis. This segmentation enables the fan assembly to be detached for cleaning while maintaining structural stability when connected, resolving the contradiction between fixed stability and cleaning accessibility.
2Stability of the object's composition
If the fan assembly is fixed non-removably on the chassis, then the structural stability is improved, but the ease of repair deteriorates
Solution Approach 1:
The fan assembly is divided into a separable component that can be removably connected to the front frame and chassis via buckles. This allows the motor and other components within the fan assembly to be easily accessed and replaced by simply removing the fan assembly, without requiring disassembly of the entire housing structure.
3Ease of operation
If the fan assembly is made removable from the front frame and chassis, then the ease of cleaning is improved, but the device complexity increases
Solution Approach 1:
The connection mechanism is extracted as a separate, standardized buckle system that can be easily engaged and disengaged. The buckles are integrated into the front frame and chassis structures, providing simple snap-fit connections that reduce overall device complexity while enabling easy removal and cleaning of the fan assembly.

AI summary
Disclosed are an indoor unit and an air conditioner having the indoor unit. The indoor unit has a housing having a chassis that can be mounted to a wall, and a front frame connected with the chassis, in which the front frame and the chassis can be joined to define a mounting cavity having a mounting mouth opened downwards, and a fan assembly positioned in the mounting cavity and exposed to an outside at the mounting mouth, in which the fan assembly can be removably connected with the front frame and the chassis.
