Dehumidifier Duct Blades for Straight Airflow Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dehumidifiers suffer from inefficient air discharge due to off-center air currents, which reduces indoor dehumidifying efficiency and limits user control over the direction of discharged air.
Innovation Solution
A dehumidifier design featuring fixed blades and rotating blades within a duct structure that splits and directs air currents, combined with a dispersion plate, to convert off-center air flows into straight, dispersed air streams that can be directed as desired, utilizing a duct with increasing cross-sectional area and slope configurations to maintain airflow velocity and enhance dispersion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a blower type blowing fan is used, then the fan can provide suction and blowing force, but the discharged air becomes off-center along the rotation direction, reducing dehumidifying efficiency
Solution Approach 1:
Fixed blades are installed as an intermediary component between the blowing fan and the discharge opening. These blades intercept the off-center air current from the fan and redirect it through a duct to achieve straight, controlled discharge. The fixed blades act as a mediator that transforms the unwanted off-center flow into a desirable straight air current, resolving the contradiction between fan performance and air current control.
Solution Approach 2:
The air current is segmented by the fixed blades into multiple controlled paths within the duct. By dividing the single off-center air stream into segmented flows that can be individually directed, the system achieves better overall control and straighter discharge pattern, improving dehumidifying efficiency while maintaining the fan's blowing capability.
2Productivity
If the discharged air current is not controlled, then the fan structure remains simple, but indoor dehumidifying efficiency is lowered
Solution Approach 1:
The system incorporates rotatable blades that can dynamically adjust the discharge direction of air currents. This dynamic component allows the dehumidifier to adapt to different operational requirements and spatial configurations, maximizing dehumidifying efficiency in various indoor environments while keeping the overall structure relatively simple through targeted complexity only where needed for control.
