Ion-Bar Self-Cleaning Mechanism for Static Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current ion-bar structures for static elimination in washing machines suffer from reduced efficiency due to particle accumulation on the discharging needle tip, which cannot be cleaned in time during monthly maintenance, affecting static elimination performance.
Innovation Solution
An ion-bar structure with a self-cleaning function, featuring a slide assembly and a brush assembly with a round-disk hairbrush and dust-rid adhesive pad, which automatically cleans the ion-bar body by sliding along a chute slide track and using a motor-driven wheel to remove dust and debris.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ion bar is cleaned only during monthly maintenance, then the maintenance frequency is low and operation is simple, but particles accumulate on the needle tip and static elimination efficiency deteriorates
Solution Approach 1:
The ion bar structure enables self-cleaning through an automatic sliding mechanism. The cleaning component slides along the ion bar body during operation to remove particles from the needle tip automatically, without requiring external intervention or scheduled maintenance. This self-service approach ensures continuous static elimination efficiency while minimizing manual maintenance requirements.
2Reliability
If the ion bar structure is simple without cleaning mechanisms, then device complexity is low and manufacturing is easy, but dust accumulates excessively and static elimination performance deteriorates
Solution Approach 1:
The cleaning function is segmented into a separate, modular component that can slide independently along the ion bar body. This segmentation allows the cleaning mechanism to be added without fundamentally redesigning the entire ion bar structure. The cleaning component includes a brush or wiping element that contacts the needle tip area, enabling effective particle removal while maintaining relatively simple overall device complexity.
3Reliability
If manual cleaning is performed during monthly maintenance, then cleaning cost is low and device complexity is low, but cleaning frequency is insufficient and particle accumulation occurs
Solution Approach 1:
The cleaning mechanism operates continuously or periodically during ion bar operation, maintaining constant particle removal from the needle tip. This continuous cleaning action ensures that particles are removed as they accumulate, preventing the deterioration of static elimination efficiency. The sliding mechanism is driven to move the cleaning component along the ion bar body throughout the operational cycle, providing uninterrupted cleaning coverage.
