Air Conditioner Door Assembly With Guided Stable Outlet Closure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner indoor unit door assemblies have poor limiting and guiding effects, leading to instability and imprecise movement trajectories, which affect the closure of air outlets and the quality of air processed.
Innovation Solution
A door assembly for air conditioner indoor units featuring a door mounting plate with a receiving groove and a guiding groove, where a guiding part connected to the door slides along the guiding groove, driven by a drive assembly, enhancing stability and precision of the door's movement trajectory.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a door is provided to close the air outlet when the air conditioner stops running, then the quality of air sent by the air conditioner is improved, but the door stability and movement trajectory control deteriorate
Solution Approach 1:
A guiding part is introduced as an intermediary component between the door and the door mounting plate. The guiding part includes a guiding portion that fits into a guiding groove, mediating the interaction and providing stable guidance while the door performs its closing function to maintain air quality.
Solution Approach 2:
The guiding function is extracted from the door assembly and implemented as a separate guiding part with a guiding groove in the door mounting plate. This separation allows the door to focus on its primary function of closing the air outlet while the guiding part independently provides trajectory control and stability.
2Reliability
If a door is provided to close the air outlet when the air conditioner stops running, then the quality of air sent by the air conditioner is improved, but the movement trajectory precision deteriorates
Solution Approach 1:
The guiding part acts as an intermediary that translates the door's movement into a precise trajectory. The guiding groove defines the exact path, ensuring the door moves along a controlled trajectory while maintaining its air quality protection function.
Solution Approach 2:
The trajectory control function is extracted and implemented through the guiding groove structure in the door mounting plate. This separate guiding mechanism ensures precise movement trajectory independent of the door's primary closing function.
3Ease of operation
If the door is limited and guided by the driving mechanism, then the door can be driven to move, but the limiting and guiding effect deteriorates
Solution Approach 1:
The guiding part serves as a mediator between the driving mechanism and the door. It receives the driving force and translates it into controlled movement along the guiding groove, improving both ease of operation and the limiting-guiding effect simultaneously.
Solution Approach 2:
The door assembly is segmented into distinct functional components: the door itself, the guiding part with guiding groove, and the driving mechanism. This segmentation allows each component to optimize its specific function - the guiding part provides stable limiting and guiding while the driving mechanism ensures easy operation.

AI summary
A door assembly for an air conditioner indoor unit includes a door mounting plate, a door, a guiding part, and a drive assembly. The door mounting plate includes a receiving groove and a guiding groove. The door is configured to be movable in a direction approaching and away from the door mounting plate. The guiding part is connected with the door, located at a side of the door facing the door mounting plate, and movably disposed in the guiding groove. The drive assembly is configured to drive the door to move, and is disposed in the receiving groove.
