Solution Overview
Problem
The existing wall-mounted air conditioner indoor units have a complicated and inconvenient process for disassembly and assembly of the air duct assembly, making maintenance, cleaning, and replacement difficult and costly.
Innovation Solution
A wall-mounted air conditioner indoor unit design featuring a housing with a face frame and a chassis that includes a movably mounted air duct assembly with a mounting bracket, allowing for easy access and detachment along an up-down direction, facilitated by sliding slots and locking mechanisms for secure reassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the air duct assembly is fixed securely to the chassis and face frame, then the installation stability is improved, but the disassembly and assembly process becomes complicated and inconvenient
Solution Approach 1:
The air duct assembly is segmented into modular components including the air duct, mounting bracket, and connection components. The mounting bracket is separately connectable to both the chassis and face frame, allowing the air duct assembly to be divided into detachable sections that can be easily removed and reinstalled while maintaining secure connections during operation
Solution Approach 2:
The connection mechanism between the mounting bracket and the chassis/face frame uses dynamic fastening elements such as screws or clips that can be easily tightened for secure installation and quickly loosened for disassembly. This allows the connection strength to be adjusted between a fixed secure state during operation and a easily detachable state for maintenance
2Ease of repair
If the air duct assembly is made detachable for easy cleaning, then the maintenance convenience is improved, but the installation stability deteriorates
Solution Approach 1:
The air duct assembly is divided into separable modules with the mounting bracket serving as an independent connection component. This segmentation allows the air duct to be easily detached from the face frame for cleaning while the mounting bracket remains attached to the chassis, maintaining structural stability during maintenance operations
Solution Approach 2:
The mounting bracket is pre-installed and securely fastened to the chassis before the air duct is attached to the face frame. This preliminary securing action ensures that when the air duct is detached for cleaning, the mounting bracket and its connection to the chassis remain stable, preventing any instability in the overall installation
3Ease of repair
If multiple components are removed to access the air duct assembly, then the air duct assembly can be cleaned, but the disassembly process becomes time-consuming and complex
Solution Approach 1:
The mounting bracket is extracted as a separate, independently detachable component from the traditional integrated air duct assembly. This extraction allows the air duct to be removed from the face frame without needing to remove the panel, face frame, or heat exchanger, as the mounting bracket provides a direct access point for detaching and cleaning the air duct
Solution Approach 2:
The air duct assembly is segmented into the air duct portion and the mounting bracket portion, with the mounting bracket serving as an intermediate connection element. This segmentation creates a direct removal path where the air duct can be detached from the face frame through the mounting bracket without requiring the removal of other components, significantly reducing disassembly time and complexity

AI summary
An air conditioner indoor unit includes a housing, a chassis, and an air duct assembly. The housing includes a face frame including an inner cavity having an opening. The chassis covers a side of the face frame. The air duct assembly includes a mounting bracket movably mounted at the chassis and detachably connected with the face frame. The mounting bracket is configured to move into or out of the inner cavity through the opening of the inner cavity along an insertion direction.
