Rotatable Diffuser Assembly for Airflow Direction Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air conditioners lack an efficient mechanism to easily regulate airflow direction, limiting user control over the distribution of cooled or heated air within a space.
Innovation Solution
The air conditioner incorporates an airflow regulator system that includes a fan assembly, a diffuser assembly with a rotatable grill and blades, and a guide unit, allowing for adjustable airflow direction through rotation of the grill and blades, driven by a motor and gear unit, enabling horizontal or vertical direction changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fixed diffuser assembly is used, then the structure is simple, but the airflow direction cannot be regulated
Solution Approach 1:
The diffuser assembly is designed with rotatable components (grill and blades) that can dynamically change position to regulate airflow direction. The grill rotates around a vertical axis while blades rotate around a horizontal axis, transforming a static structure into a dynamic one capable of directional control.
Solution Approach 2:
The diffuser assembly is divided into independent rotatable segments including the grill and individual blades. Each segment can be controlled separately by independent motors, allowing precise regulation of airflow direction without requiring movement of the entire assembly.
2Ease of operation
If the entire diffuser assembly rotates, then airflow direction changes effectively, but the required space and structural complexity increase
Solution Approach 1:
Instead of rotating the entire diffuser assembly, only specific segments (grill and blades) are made rotatable. This segmentation allows airflow direction control while minimizing the space required and reducing structural complexity compared to rotating the complete assembly.
Solution Approach 2:
The grill rotates around a vertical axis while blades rotate around a horizontal axis, utilizing different dimensional rotations to achieve comprehensive airflow direction control without requiring large rotational space for the entire assembly.

AI summary
An air conditioner including an improved airflow regulator is configured to easily regulate the airflow. The air conditioner includes a fan assembly configured to blow air a diffuser assembly configured to include a center panel and a grill arranged at the outside of the center panel such that the air blown by the fan assembly flows through a flow passage formed between the center panel and the grill; and an airflow regulator configured to rotate the diffuser assembly so as to change a direction of the flow passage.
