Fine Dust Collecting Body With Gravity-Based Filter Regeneration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bagless vacuum cleaners face the issue of fine dust filters clogging due to limited absorption capacity, requiring frequent washing or replacement, which contradicts the philosophy of being consumable-free and leading to decreased suction power over time.
Innovation Solution
Incorporating a sedimentation vessel below the fine dust filter to act as an additional dust storage, allowing fine dust to settle under gravity, and using a vibrating device to regenerate the filter by loosening dust from the surface and guiding it into the sedimentation vessel, thereby extending the filter's service life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fine dust filter is used in a bagless vacuum cleaner, then fine dust can be filtered effectively, but the filter becomes clogged over time requiring frequent washing or replacement
Solution Approach 1:
The dust collection system is segmented into two distinct functional zones: an upper fine dust filter for filtration and a lower sedimentation vessel for dust storage. This segmentation allows the filter to be regenerated by draining accumulated dust into the sedimentation vessel, extending service life without compromising filtration effectiveness
Solution Approach 2:
The sedimentation vessel acts as an intermediary storage zone between the fine dust filter and the external environment. It temporarily holds accumulated dust, enabling the filter to be regenerated multiple times before final disposal, thus extending the overall system service life
2Productivity
If the fine dust filter is washed frequently to regenerate it, then suction power is maintained, but the filter characteristics are impaired
Solution Approach 1:
Instead of washing the filter to remove dust, the invention extracts accumulated dust from the filter into the sedimentation vessel through gravity-driven drainage. This mechanical extraction method maintains filter characteristics while restoring suction power, avoiding the degradation caused by frequent washing
3Reliability
If the fine dust filter is replaced after several years, then filtration performance is restored, but this contradicts the bagless vacuum cleaner philosophy of being consumable-free
Solution Approach 1:
The system recovers dust accumulation capacity by providing a separate sedimentation vessel for dust storage. The filter can be regenerated multiple times by draining dust into the vessel, reducing replacement frequency and aligning with the consumable-free philosophy while maintaining filtration performance
