Mesh Filter Self-Cleaning Air Cleaner for Dust Buildup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air cleaners face issues with dust accumulation on the filter surface near the air inlet, leading to reduced air-drawing efficiency and the need for frequent manual cleaning, which can result in dust scattering when the filter is removed.
Innovation Solution
An air cleaner design featuring a mesh-type filter body with a rotation brush unit and a drop guide unit that automatically removes dust from the filter surface, guiding it into a dust collector, eliminating the need for manual cleaning and preventing dust from being scattered.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter assembly is used to remove dust from indoor air, then air purification effectiveness is improved, but dust accumulates on the filter surface reducing air-drawing efficiency
Solution Approach 1:
The rotation brush unit performs preliminary cleaning action on the filter surface before dust accumulation significantly impacts air-drawing efficiency. By continuously or periodically removing dust particles from the filter mesh, the system maintains optimal airflow while preserving the filter's purification function.
Solution Approach 2:
The filter assembly performs self-cleaning through the rotation brush unit that automatically removes accumulated dust without requiring manual intervention. The dust collector gathers the removed dust, enabling the filter to maintain its performance autonomously.
2Ease of operation
If the filter assembly is separated from the body to remove dust manually, then dust removal is achieved, but dust scatters and pollutes the indoor atmosphere
Solution Approach 1:
The system performs automatic dust removal through the rotation brush unit and dust collector combination, eliminating the need for manual filter separation. Dust is contained and collected within the sealed dust collector chamber, preventing scattering into the indoor environment.
Solution Approach 2:
The dust collector acts as an intermediary containment chamber that receives dust from the filter surface and stores it securely. This intermediate structure prevents direct contact between removed dust and the indoor atmosphere, allowing safe dust management.
3Productivity
If manual cleaning of the filter is performed frequently, then air-drawing efficiency is maintained, but user time and effort are consumed
Solution Approach 1:
The rotation brush unit and dust collector system provides automatic self-maintenance, continuously or periodically removing dust from the filter surface without user intervention. This eliminates the time and effort previously required for manual cleaning while maintaining optimal air-drawing efficiency.
Solution Approach 2:
The automatic dust removal system operates continuously or periodically to maintain filter performance, ensuring uninterrupted air-drawing efficiency. Unlike manual cleaning which occurs in discrete intervals, the automated system provides continuous maintenance, preventing efficiency degradation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The automatic dust removal system ensures continuous air cleaner efficiency by preventing dust accumulation on the filter surface, reducing maintenance needs and preventing dust from being reintroduced into the indoor atmosphere.
Implementation Method 1
a rotation brush unit installed on an inner wall surface of the front panel to face a front surface of the mesh-type filter body and adapted to rotate while maintaining contact with the front surface of the mesh-type filter body
Implementation Method 2
a drop guide unit is formed on a lower portion of a region of the cover body, the opening being formed in the region, to guide falling alien substances separated from the front surface of the mesh-type filter body by the rotation brush unit
