Ceiling-Embedded Airflow Layout for Room Corner Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional ceiling-embedded air conditioners have difficulty blowing air to the corners of a room effectively, leading to temperature variations and inefficient air conditioning in large spaces due to complex structures and the need for auxiliary outlets, which compromise the strength of the drain pan and increase the number of components.
Innovation Solution
A ceiling-embedded air conditioner design featuring a box-shaped housing with a square decorative panel, main body outlets along the sides, corner blowoff units, and rotatable wind direction plates that guide air to the corners without auxiliary outlets, ensuring efficient air distribution and maintaining the structural integrity of the drain pan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional outlets are provided only along the four sides of the housing, then the structure is simple, but air cannot be blown effectively to the corners of the room
Solution Approach 1:
The outlet configuration is segmented into two distinct types: side outlets positioned along the four sides of the housing for general air distribution, and corner outlets positioned at the four corners for targeted corner coverage. This segmentation allows each outlet type to perform its specific function optimally, resolving the contradiction between simple structure and effective corner air distribution.
2Ease of operation
If auxiliary outlets are added to blow air to corners, then air distribution improves, but the drain pan strength is compromised and component count increases
Solution Approach 1:
The corner outlets are merged with the drain pan structure, forming an integrated design where the outlets are positioned at the corners of the drain pan. This merging allows the drain pan to serve dual functions: draining condensation water and providing air distribution pathways to corners, thereby improving air distribution coverage without compromising drain pan strength or increasing component count.
3Ease of operation
If wind direction plates are made longer than the outlet sides, then air can be directed to corners, but the plate length increases
Solution Approach 1:
The wind direction plates are designed to be rotatable, allowing dynamic adjustment of air flow direction. The plates can rotate to align with different outlet orientations, enabling air to be directed toward corners when needed. This dynamic capability provides effective wind direction control without requiring permanently extended plate lengths, thus resolving the contradiction between directional control and plate dimensions.

AI summary
A ceiling-embedded air conditioner includes: a box-shaped housing that is embedded in a ceiling of an air-conditioned room; a square decorative panel that is attached to a lower surface of the housing and covers the ceiling; main body outlets that are provided along respective four sides of a bottom surface of the housing and blow heat-exchanged air; outlets that are provided in the decorative panel in correspondence with the main body outlets; corner blowoff units that are provided in the decorative panel in correspondence with coupling portions for coupling the outlets; a blowoff path that is circumferentially provided in the decorative panel in correspondence with the outlets and the corner blowoff units; and wind direction plates that are rotatably provided along the respective sides of the decorative panel so as to cover or open the blowoff path and are longer than a long side of the outlets.
