Ceiling Cassette Air Outlet Flaps for Draft-Free Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ceiling-embedded type air conditioners with visible main and sub-flaps mar the appearance while attempting to control air direction and speed, and they often cause unpleasant cold drafts during cooling operations.
Innovation Solution
The air conditioner features a main flap and a sub-flap with a second guide part that changes air direction, where the main flap extends downward and has a wider second guide part than the sub-flap, allowing for adjustable airflow direction and speed without being visible, and includes a heat insulating member to prevent dew condensation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If main flap and sub-flap are installed to control air direction, then air guidance function is improved, but appearance is marred due to visible flaps and parting lines
Solution Approach 1:
The sub-flap is nested within the main flap structure, where the sub-flap is positioned inside the contour formed by the main flap. This nesting arrangement allows both flaps to function independently for air direction control while the main flap visually conceals the sub-flap and parting lines, maintaining a clean appearance without visible mechanical components.
2Adaptability or versatility
If flaps are designed to be visible for function, then air guidance capability is improved, but design aesthetics deteriorate
Solution Approach 1:
The main flap and sub-flap are designed with different local qualities: the main flap has a larger contour area that serves as both a functional air guidance element and a visual concealing structure, while the sub-flap has a smaller area optimized for precise air direction control. This differential design allows the system to achieve versatile air guidance while maintaining aesthetic appearance through the main flap's visual dominance.
3Object-affected harmful factors
If air outlet is compressed to guide air laterally, then cold draft is reduced, but airflow speed control becomes more complex
Solution Approach 1:
The main flap and sub-flap are designed as dynamic components that can rotate independently to different angles, allowing real-time adjustment of the air outlet compression degree. This dynamic configuration enables the system to adaptively control airflow direction and speed, reducing cold drafts by compressing the air outlet when needed while maintaining simple mechanical structures through independent rotational movements.

AI summary
Disclosed herein is an air conditioner capable of guiding air in a desired direction with an adjusted speed without marring the appearance to solve the above-described problems. An air conditioner comprising a ceiling-embedded type indoor unit configured to discharge air into an indoor room through an air outlet simultaneously sucking indoor air through an air inlet, wherein a air conditioner comprises, a main flap configured to guide a direction of air discharged from a air outlet in a preset direction, and a sub-flap configured to guide the direction of air between the main flap and the sub-flap in the preset direction, wherein a length of a main flap in a direction where air flows is longer than that of the sub-flap in the direction where air flows.
