Rotatable Auxiliary Air Outlet Layout for Stable Airflow Direction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioners lack the ability to finely control the orientation and movement of airflow from auxiliary air outlets, which affects the temperature environment in a room, and fail to maintain airflow force when auxiliary housings are displaced.
Innovation Solution
The air conditioner incorporates auxiliary air outlets positioned below the main air outlet, with separate blower fans for the main and auxiliary airflows, allowing for adjustable wind speeds and orientations, and a centrifugal fan with a rotating shaft aligned with the auxiliary housing to maintain airflow force even when the housing rotates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If auxiliary air outlets are positioned on both sides of the air outlet, then the airflow orientation control is improved, but the airflow force may be lost due to collision with the main airflow
Solution Approach 1:
The auxiliary air outlets are positioned below the main air outlet in the vertical dimension rather than horizontally adjacent, eliminating spatial collision between airflows while maintaining orientation control capability through separate blower fans
2Adaptability or versatility
If auxiliary housings are made rotatable to adjust airflow direction, then the adaptability is improved, but the airflow force may be lost when the housing is displaced
Solution Approach 1:
The auxiliary housing is designed to be rotatable around a rotation shaft that overlaps with the centrifugal fan's rotation shaft, allowing dynamic adjustment of airflow direction while the aligned configuration ensures the airflow force is maintained even when the housing is displaced to different positions
Solution Approach 2:
The air conditioning device is divided into independent main and auxiliary systems with separate blower fans, allowing the auxiliary housing to rotate independently without affecting the main airflow, thus maintaining airflow force while providing directional adaptability
3Measurement precision
If separate blower fans are used for main and auxiliary airflows, then the airflow control precision is improved, but the device complexity increases
Solution Approach 1:
The centrifugal fan serves dual purposes: it generates the main airflow and also drives the auxiliary airflow when the auxiliary housing is rotated into position, reducing the need for completely separate fan systems while maintaining precise airflow control
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 configuration enables precise control of airflow orientation and movement, effectively maintaining airflow force and improving indoor temperature regulation by directing air to desired locations without collision or loss of force.
Implementation Method 1
a second blower fan that is stored in the auxiliary housing and generates the airflow of the indoor air... The second blower fan can be a centrifugal fan which rotates around a rotation shaft
Implementation Method 2
cool air or warm air that is heat-exchanged by a heat exchanger from an air outlet of an indoor unit

AI summary
It is possible to provide an air conditioner which can effectively maintain a force of an airflow even when an auxiliary air outlet is displaced. A structural body forms an air outlet 31 which blows out a cool or warm airflow. Auxiliary housings 35 are attached to both sides of the air outlet 31 to be freely rotatable around a horizontal shaft line 36. The auxiliary housing 35 blows out indoor air from an auxiliary air outlet 42. A distance L1 from an imaginary shaft line which includes a rotation shaft of the auxiliary housing 35 to the auxiliary air outlet is set to be longer than a distance L3 from the imaginary shaft line to the air outlet 31 of the structural body 28.
