Rotatable Air Conditioner Wind Visors for Quiet Lateral Airflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing indoor air conditioner designs with wind visors are complex in structure, require unnecessary deformation of the main body for installation, and lack a simple mechanism for adjusting the discharge angle of air, leading to inefficient air flow and potential noise issues due to lateral air collisions and lack of a separate fixing structure.
Innovation Solution
The design incorporates a wind visor with a guide plate and a fixing portion that allows for easy rotation and adjustment of the discharge angle, integrated with a panel and corner cover system, enabling smooth air flow and easy installation without deforming the main body, and allows for the wind visor's removal without compromising the device's appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the wind visor is fixed to the indoor device with a complex connection part and joint part structure, then the air discharge direction can be adjusted, but the device structure becomes complicated and the exterior appearance deteriorates when the wind visor is removed
Solution Approach 1:
The wind visor is divided into a separate detachable component with a simple connection structure. The connection part includes a limited number of positioning holes that align with corresponding positions on the discharge hole, allowing the wind visor to be easily attached and detached without complex joint structures. This segmentation resolves the contradiction by simplifying the overall structure while maintaining adjustability functionality.
Solution Approach 2:
The connection part is designed to serve multiple functions: it provides structural support, enables angular adjustment through positioning holes, and allows easy attachment and detachment. This multi-functionality reduces the need for separate complex joint structures, thereby simplifying the overall device structure while maintaining the ability to adjust air discharge direction.
2Reliability
If the wind visor is installed by punching and deforming the main body, then the wind visor can be securely attached, but the main body structure is damaged and requires additional finishing materials
Solution Approach 1:
The positioning holes are pre-formed on the discharge hole structure before wind visor installation. This preliminary preparation eliminates the need for punching or deforming the main body during installation. The wind visor connection part simply needs to align with these pre-formed holes, enabling secure attachment without damaging the main body structure or requiring additional finishing materials.
3Area of stationary object
If the discharge holes are positioned close to each other to save space, then the device size is reduced, but the discharged air from adjacent holes collides laterally causing noise and inefficient air flow
Solution Approach 1:
The wind visor is designed with different angular positions available at different locations. The positioning holes are arranged to provide optimal air discharge angles for each specific discharge hole location. This local customization of discharge angles ensures that air flows from adjacent discharge holes do not collide laterally, preventing noise generation while maintaining compact device dimensions.
Solution Approach 2:
The wind visor can be rotated to different angular positions to dynamically adjust the air discharge direction. This dynamic adjustability allows optimization of air flow patterns for each discharge hole based on its specific location and the positions of adjacent discharge holes, preventing lateral air collision and noise while maintaining compact device size.

AI summary
An indoor device for an air conditioner having wind visors is provided. Each wind visor may have a shape corresponding to a shape of a respective discharge hole of the indoor device and may be directly rotatably mounted on a bottom surface of the indoor device to guide discharged air, thereby providing a simplified structure. A fixing portion, on which the wind visor may be installed, may be provided in the indoor device, and the wind visor may be rotatably coupled to the fixing portion through the simplified structure.
