Air Purifier Electrostatic Filter Segmentation for Separate Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air purifiers with integrated electrostatic filter elements face difficulties in thorough cleaning due to fragile emission wires and internal pollutant accumulation on the housing, making regular maintenance challenging.
Innovation Solution
The design includes a detachable protective cover with a detachable emission assembly and collection assembly, allowing for separate cleaning and reducing the risk of housing damage, with a staggered arrangement of electrode plates for improved washing efficiency and ventilation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the electrostatic filter element is integrated with emission wires and collection plates, then the device structure is simplified, but the cleaning becomes difficult and the emission wires are prone to fracture
Solution Approach 1:
The electrostatic filter element is divided into separate emission wires and collection plates that can be independently removed and cleaned. The collection plates are detachably connected to the housing, allowing them to be separated from the emission wires for independent cleaning without risking damage to the fragile emission wires.
2Device complexity
If the electrostatic filter element is integrated, then the device structure is simplified, but the emission wires are prone to fracture under external force
Solution Approach 1:
The emission wires are separated from the collection plates, allowing the fragile emission wires to remain fixed in the housing while the collection plates are detachable. This prevents external forces applied during cleaning from damaging the emission wires.
Solution Approach 2:
The collection plates are extracted as separate detachable components from the integrated filter element, allowing them to be removed for cleaning while the emission wires remain in place, protected from external forces.
3Device complexity
If pollutants accumulate on the inner wall of the housing, then the housing structure is simple, but the pollutants are difficult to wash
Solution Approach 1:
The collection plates are extracted as detachable components that can be removed from the housing for cleaning. Pollutants that would otherwise accumulate on the inner wall of the housing are instead collected on the removable collection plates, which can be easily washed separately.
4Device complexity
If the electrostatic filter element is integrated, then the device structure is simplified, but thorough washing is hardly achieved
Solution Approach 1:
The filter element is segmented into detachable collection plates and fixed emission wires. This allows the collection plates to be completely removed and washed thoroughly on both sides, achieving cleaning thoroughness that would be impossible with an integrated structure.
