Auxiliary Air Outlet Control for Airflow Direction in Air Conditioners
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners face challenges in effectively utilizing airflow from secondary air outlets, leading to inefficient indoor temperature regulation and discomfort due to uneven airflow distribution and lack of control over airflow orientation.
Innovation Solution
An air conditioner design featuring a structural body with a first air outlet and an auxiliary housing with a second air outlet, where the second air outlet is adjustable and blows indoor air at a higher wind speed than the first air outlet, allowing for controlled airflow direction and distribution to optimize indoor temperature regulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the second air outlet blows out air at high wind speed to influence the cool or warm airflow, then the airflow control effectiveness is improved, but the noise from the blower increases
Solution Approach 1:
The patent changes the wind speed parameter of the second air outlet to be higher than the first air outlet, enabling the secondary airflow to effectively influence and redirect the primary cool or warm airflow. This parameter optimization ensures that the blower operates at an efficient speed range that maintains airflow control effectiveness while minimizing unnecessary noise generation.
2Volume of stationary object
If the second air outlet area is made smaller to reduce housing size, then the device compactness is improved, but the wind speed generation capability may be reduced
Solution Approach 1:
The patent optimizes the relationship between the second air outlet area and blower speed, determining that a smaller outlet area combined with appropriate blower speed control can generate sufficient wind speed to influence the primary airflow without requiring a large housing. This parameter optimization allows compact design while maintaining airflow control effectiveness.
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
This design enhances indoor temperature control by ensuring cool air is directed effectively and warm air remains near the floor, reducing noise and maintaining a comfortable temperature environment while minimizing the size of the air conditioner.
Implementation Method 1
The airflow which passes through the dust collection filter is generated in a centrifugal fan
Implementation Method 2
blows out cool air or warm air that is heat-exchanged by a heat exchanger

AI summary
Air-blowing from a second air outlet is effectively used. An air conditioner includes a main body unit and an auxiliary housing. The main body unit forms a first air outlet which blows out a cool or warm airflow. The auxiliary housing is attached to at least one side of the first air outlet to be freely movable, and forms a second air outlet which blows out taken-in indoor air. A control circuit blows out the indoor air from the second air outlet at a wind speed which is higher than the wind speed of cool air or warm air that is blown out of the first air outlet.
