Airborne Dust Cleaner With Vortex Collection for Fan Noise
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air purifiers have a weak dust suction force due to the limitations of their fans, which results in ineffective dust removal and increased power consumption, noise, and vibration, while their design also leads to inefficient air circulation patterns.
Innovation Solution
An airborne dust cleaner with a vortex vacuum generator at the inlet creates a low-pressure donut-like vortex to enhance dust collection, combined with a filtering assembly and a compact design for improved efficiency and reduced noise and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the air volume of the fan is increased to improve dust suction force, then the dust collection capability is improved, but the power consumption becomes excessively large and vibration and noise become substantial
Solution Approach 1:
The patent employs a vortex vacuum generator that utilizes vortex flow dynamics to create low-pressure zones for dust collection. This pneumatic approach replaces the conventional fan-based suction system, achieving effective dust collection through controlled vortex flow patterns rather than high-volume fan operation, thereby reducing power consumption while maintaining dust suction capability
Solution Approach 2:
The invention changes the operating parameters of the dust collection system by transitioning from high-volume low-pressure fan operation to controlled vortex flow with specific rotational velocities. The vortex vacuum generator creates optimized flow patterns that improve dust collection efficiency without requiring excessive air volume, thus reducing power consumption and vibration noise
2Productivity
If the air volume of the fan is increased to improve dust suction force, then the dust collection capability is improved, but the vibration and noise generated from the fan become substantial
Solution Approach 1:
The vortex vacuum generator uses pneumatic vortex flow to create dust collection currents, eliminating the need for high-speed rotating fans that generate vibration and noise. The system achieves dust suction through controlled vortex dynamics and low-pressure zone formation, significantly reducing mechanical vibration and acoustic noise
Solution Approach 2:
The patent replaces the mechanical fan-based suction system with a vortex flow-based pneumatic system. This substitution eliminates the mechanical rotation and blade interactions that cause vibration and noise, achieving dust collection through fluid dynamic principles instead of mechanical force
3Reliability
If a conventional fan structure is used with filters placed in front, then the device can filter air, but the dust suction force is further lowered due to the differential pressure of the filters
Solution Approach 1:
The patent merges the vortex generation and dust collection functions into a single integrated vortex vacuum generator unit. This combined structure eliminates the need for separate fan and filter assemblies, allowing vortex flow to directly draw dust particles through the filtering system without the differential pressure losses associated with conventional fan-filter configurations
Solution Approach 2:
The vortex vacuum generator uses pneumatic flow to create a pressure differential that draws dust particles through the filter media. This pneumatic approach maintains positive flow pressure throughout the system, avoiding the negative pressure differential losses that occur in conventional fan-based systems where filters are placed in front of the fan
4Device complexity
If the inlet is positioned on the front side and outlet on the upper side, then the device structure is simple, but the contaminated air around the air cleaner is not introduced into the inlet and air rises toward the ceiling then falls back to the ground
Solution Approach 1:
The vortex vacuum generator introduces a rotational dimension to the airflow pattern, creating a three-dimensional vortex flow that draws contaminated air from all directions around the device rather than relying on simple front-to-back or bottom-to-top flow. This dimensional change in flow pattern improves air circulation efficiency without complicating the physical positioning of inlet and outlet openings
