Panel assembly for air conditioner and window air conditioner
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air conditioner designs often result in direct air blowing towards users, leading to discomfort, and are prone to face frame deformation due to long air flow paths and large air inlets, causing inefficiency and aesthetic issues.
Innovation Solution
A panel assembly for air conditioners featuring an air outlet above the air inlet with an obliquely extending outlet surface, a mesh-shaped air inlet panel, and a reinforcing support to reduce air flow path length, increase blowing distance, and prevent face frame deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the air outlet is arranged below the air inlet with a horizontal outlet surface, then the structure is simple, but the air blowing distance is short and cold air is directly blown towards users
Solution Approach 1:
The air outlet surface is changed from horizontal to oblique, extending upward at an angle of 10-30 degrees relative to the horizontal plane. This dimensional change in the outlet surface orientation redirects the air flow upward, increasing the air blowing distance and preventing direct cold air from reaching users while maintaining structural simplicity
2Area of stationary object
If the air channel length is increased, then the air output area can be enlarged, but the air flow loss increases
Solution Approach 1:
The air channel cross-sectional area is dynamically adjusted along its length, with the area being progressively enlarged from the inlet to the outlet. This dynamic area expansion allows the air channel to maintain lower flow velocity and reduced turbulence throughout its length, thereby minimizing air flow loss while achieving a large air output area
3Productivity
If the air inlet area is enlarged, then the air intake capacity is improved, but the face frame becomes prone to deformation
Solution Approach 1:
The large air inlet area is segmented into multiple smaller inlet openings distributed across the face frame. This segmentation maintains the total air intake capacity while distributing the structural load, preventing face frame deformation. The segmented inlets are arranged in a pattern that optimizes both airflow and structural integrity
4Ease of operation
If the air outlet is positioned to blow air horizontally, then the structure is simple, but the cold air is directly blown towards persons causing discomfort
Solution Approach 1:
The air outlet surface is oriented obliquely at 10-30 degrees upward from horizontal, changing the air flow direction from horizontal to upward-sloping. This dimensional change in outlet orientation naturally redirects cold air away from users, improving comfort without requiring complex air channel configurations or additional control mechanisms

AI summary
A panel assembly for an air conditioner includes a face frame and an air inlet panel. The face frame includes an air inlet and an air outlet located above the air inlet. An air outlet surface of the air outlet extends obliquely backward in a direction from bottom to top. The air outlet surface is a plane on which an end surface of the air outlet is located. The air inlet panel is provided at the air inlet.
