Dual Air Deflector Venting for No-Wind Air Conditioner Outlets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners often blow cold wind directly, which is uncomfortable for users, especially vulnerable groups like the elderly, pregnant women, and children, and can lead to related health issues.
Innovation Solution
An air conditioner indoor unit with an outer and inner air deflector system featuring vent holes that reduce air speed and volume, allowing for various wind modes, including a no-wind mode, by adjusting the air outlet and deflector positions and angles to control airflow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the air outlet is opened to provide cooling air flow, then the cooling effect is improved, but the air speed and direct wind blowing toward users increases causing discomfort and health issues
Solution Approach 1:
The air outlet is divided into multiple vent holes (first vent holes in the outer air deflector and second vent holes in the inner air deflector) instead of a single large opening. This segmentation distributes the air flow into multiple smaller streams, reducing the air speed at each vent while maintaining the overall cooling effect through cumulative air flow.
2Temperature
If the air outlet is opened to provide cooling air flow, then the cooling effect is improved, but the user comfort deteriorates due to direct wind blowing
Solution Approach 1:
The air outlet is segmented into multiple vent holes that distribute air flow across different locations and directions, preventing concentrated direct wind from blowing toward users while maintaining effective cooling through distributed air circulation.
Solution Approach 2:
The inner air deflector with second vent holes is nested within the outer air deflector with first vent holes, creating a multi-layered structure that provides multiple levels of air flow control and distribution to eliminate direct wind while preserving cooling effectiveness.
3Object-affected harmful factors
If the air outlet is closed to prevent direct wind, then user comfort is improved, but the cooling effect is reduced
Solution Approach 1:
The nested dual deflector structure allows the system to maintain a closed appearance from the outside while internally distributing air through multiple vent holes, preventing direct wind exposure to users while ensuring adequate cooling air flow reaches the room.
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 air speed and volume, enhancing user comfort and preventing air-conditioning related diseases by allowing the air conditioner to switch between different wind modes, including a no-wind mode, thereby improving user experience.
Implementation Method 1
a plurality of first vent holes being formed in the outer air deflector and penetrating the outer air deflector in a thickness direction
Implementation Method 2
the first vent holes and the second vent holes formed in the outer air deflector and the inner air deflector can reduce the air speed and volume at the air outlet
