Air Conditioning Indoor Unit Panel Recess to Reduce Condensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Air conditioning indoor units face condensation issues on the front surface due to temperature differences, and existing solutions degrade the design by incorporating visible grooves to mitigate this problem.
Innovation Solution
An air conditioning indoor unit design featuring a recess between the air outlet and the panel, covered by a horizontal flap during non-operation, reduces condensation by directing cold air between the panel's back and front surfaces, thereby minimizing visible condensation and enhancing design aesthetics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a groove is added to the front surface to reduce condensation, then condensation occurrence is reduced, but the design is degraded
Solution Approach 1:
The invention extracts the groove structure from the visible front surface and relocates it to the internal structure, specifically positioning the recess between the air outlet upper edge and the panel lower end. This allows the condensation-prevention function to be maintained while the design appearance is preserved, as the recess is not visible from the exterior during non-operation.
2Ease of operation
If the horizontal flap upwardly adjusts cold air direction, then air direction control is improved, but condensation on the front surface occurs
Solution Approach 1:
The invention introduces the recess structure as an intermediary element between the air outlet and the panel. This recess acts as a buffer zone that intercepts cold air before it can reach the panel's front surface, thereby preventing condensation while allowing the horizontal flap to maintain its air direction control function.
3Object-affected harmful factors
If the recess is visible during non-operation, then the condensation prevention structure is functional, but the design is degraded
Solution Approach 1:
The invention applies local quality by creating a recess with specific dimensional characteristics (cross-sectional area of 10 mm² or more) that serves the condensation prevention function locally, while the overall front surface maintains its design appearance. The recess is strategically positioned and sized to be functional yet minimally visible during non-operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively reduces condensation on the front surface and improves the unit's design by hiding the recess and air outlet during non-operation, preventing cold air from entering and causing condensation, and reducing the visibility of the recess, thus maintaining a better appearance.
Implementation Method 1
the horizontal flap upwardly adjusts the air direction of cold air as conditioned air, the likelihood of occurrence of condensation on the front surface of the panel can be reduced when the cold air enters between a front surface of the body and a back surface of the panel
Implementation Method 2
the likelihood of occurrence of condensation on the front surface of the panel can be reduced when the cold air enters between a front surface of the body and a back surface of the panel from a joint between the lower end of the panel and the body to create a difference in temperature between the front surface side and the back side of the panel

AI summary
An air conditioning indoor unit includes a body, a panel, and a horizontal flap. The body is provided with an air outlet. The panel is positioned to cover the front of the body. The horizontal flap is able to vary the air direction of conditioned air blown out from the air outlet. A recess recessed toward the back side of the air conditioning indoor unit is disposed between an upper edge of an open peripheral edge of the air outlet and a lower end of the panel. During non-operation, the recess and the air outlet are covered by the horizontal flap.
