Air conditioner indoor unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The conventional air conditioner indoor unit has low general assembly efficiency and inconvenient disassembly, making cleaning and overhaul difficult, as it requires assembling numerous parts in a specific order and has structural limitations that prevent easy disassembly and cleaning of critical components like the air duct and fan motor.
Innovation Solution
The air conditioner indoor unit is designed with modular components, including a base module, heat exchange module, and air and water duct module, allowing for pre-assembly of parts, easy disassembly, and independent cleaning of the air duct and fan motor, with the heat exchanger and connection pipeline positioned on the same side for simplified assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If numerous and miscellaneous parts are assembled in a specific order on a general assembly line, then the air conditioner indoor unit can be manufactured with complete functionality, but the production efficiency is low and the assembly line occupies a large space
Solution Approach 1:
The air conditioner indoor unit is divided into multiple modules: a base module containing the fan motor and base part, a heat exchange module with the heat exchanger and connection pipeline, and an air and water duct module with the air duct assembly. These modules can be pre-assembled separately and then quickly combined, significantly reducing the complexity of the general assembly line and improving production efficiency.
2Ease of operation
If the air duct assembly is fixedly mounted on the base part, then the structural stability is ensured, but the disassembly is difficult and cleaning becomes inconvenient
Solution Approach 1:
The air duct assembly is designed to be movably mounted on the base part rather than fixedly attached. This dynamic mounting allows the air duct assembly to be easily disassembled for cleaning while maintaining structural stability during operation. The movable connection enables users to remove the air duct assembly independently without disassembling the fan motor or other critical components.
3Ease of manufacture
If the heat exchanger and connection pipeline are arranged on different sides or in complex positions, then the functional requirements are met, but the assembly and disassembly processes become complicated
Solution Approach 1:
The heat exchanger and connection pipeline are integrated into a unified heat exchange module, with both components arranged on the same side of the base module. This merging of components simplifies the structural arrangement, making the assembly and disassembly processes more straightforward while still meeting all functional requirements for heat exchange and refrigerant flow.
4Ease of repair
If critical components like the fan motor and electrical box are permanently fixed, then the reliability is improved, but the overhaul cost and time increase when these components need maintenance
Solution Approach 1:
The base module is designed with detachable mounting structures that allow the fan motor and electrical box to be easily removed from the base part. This segmentation enables independent maintenance and overhaul of these critical components without requiring disassembly of the entire air conditioner indoor unit, reducing both overhaul time and costs while maintaining component stability during normal operation.

AI summary
An air conditioner indoor unit is provided. The air conditioner indoor unit includes: a base module, having a base part which is arranged with a fan motor; a heat exchange module having a heat exchanger and a connection pipeline for connecting the heat exchanger to an air conditioner outdoor unit; the heat exchanger and the connection pipeline are arranged in such a way that in a mounted state, the heat exchanger and the connection pipeline are entirely located at a front side of the base module; an air and water duct module having an air duct assembly; the air duct assembly is suitable to be entirely disassembled from the base part without disassembling the fan motor in the base part. During mounting, pre-assembly is first performed and then general assembly is performed; in such manner, the time needed to assemble the whole unit may be reduced.
