Blow-Out Panel Corner Rod Structure for Uniform 360° Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioning indoor units with rectangular blow-out panels experience uneven airflow distribution, with air less likely to reach the corners of the blow-out port, leading to inefficient air dissemination.
Innovation Solution
A blow-out panel with a polygonal shape formed by an outer and inner frame, featuring a connecting rod that guides airflow to the corners, reducing directional loss and ensuring uniform airflow distribution by forming an inwardly concave shape with its surfaces, allowing air to be blown out 360° uniformly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a rectangular blow-out port is adopted to increase blow-out area and layout convenience, then the blow-out area is increased, but the airflow is less likely to travel to the corner and air is blown out ununiformly
Solution Approach 1:
The patent applies local quality by providing connecting rods specifically at the corner portions of the rectangular blow-out port, rather than uniformly across the entire structure. These connecting rods create localized airflow guidance paths that direct air toward the corner regions, addressing the specific problem of poor corner airflow while preserving the overall rectangular configuration and its area advantages.
Solution Approach 2:
The connecting rods act as intermediary structures between the main airflow path and the corner regions. They serve as mediating elements that redirect and guide the airflow from the central blower toward the corner portions of the blow-out port, enabling uniform air distribution without changing the fundamental rectangular design.
2Ease of operation
If a rectangular blow-out panel is used for layout convenience, then layout convenience is improved, but spiral airflow is less likely to travel to the corner and air is blown out ununiformly
Solution Approach 1:
The patent maintains the rectangular blow-out panel configuration for layout convenience while introducing localized connecting rod structures at the corner portions. This local modification provides targeted airflow guidance to corners without disrupting the overall rectangular layout, thus preserving ease of installation and configuration.
Solution Approach 2:
The patent segments the airflow guidance function by introducing separate connecting rod structures at each corner portion, rather than attempting to modify the entire panel structure. This segmentation allows the main rectangular panel to retain its layout advantages while corner-specific airflow issues are addressed independently through localized structural additions.
3Manufacturing precision
If the connecting portion and connecting rod body form an inwardly concave shape, then airflow is guided to the corner uniformly, but the structure becomes more complex
Solution Approach 1:
The patent employs curved or concave surfaces on the connecting rod structures, particularly the inwardly concave shape formed by the connecting portion and connecting rod body. This curvature creates smooth airflow paths that guide air toward the corner portions, improving airflow uniformity while maintaining relatively simple structural forms that are easy to manufacture.

Function Achieved in This Case
The solution enables uniform airflow distribution around the blow-out port, reducing turbulence and ensuring that air is blown out efficiently in all directions, improving the overall performance of the air conditioning indoor unit.
Implementation Method 1
the second surface of the connecting portion of the connecting rod is used to easily guide an airflow generated by the axial fan or the like to the corner of the blow-out port via the second surface of the connecting rod body

AI summary
The present invention is to provide a blow-out panel and an air conditioning indoor unit that includes the blow-out panel that can blow out air 360° all around and that blows out air from a blow-out port uniformly. The blow-out panel (20) has an outer frame (21), an inner frame (22), and a connecting rod (24). A polygonal blow-out port (CF) is formed by being surrounded by the outer frame and the inner frame. A connecting rod is provided at a corner of the blow-out port and connects the outer frame and the inner frame. The connecting rod has a connecting rod body (241A) and a connecting portion (242A). The connecting portion is closer to a center of the blow-out panel than the connecting rod body, and connects the connecting rod body to the inner frame. The connecting portion and the connecting rod body each have a first surface and a second surface. As viewed from the inner surface side to the outer surface side of the blow-out panel, the first surface is disposed downstream of the second surface in the clockwise direction around the center of the blow-out panel. The second surface of the connecting portion and the second surface of the connecting rod body are combined to form an inwardly concave shape.
