Dryer Filter Assembly with Self-Closing Flap for Fluff Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clothes dryer filters require periodic manual intervention for fluff removal, which is inconvenient, or rely on automatic systems that may not effectively manage fluff separation and disposal, potentially leading to circuit obstruction and damage.
Innovation Solution
A filter assembly with a rotatable flap mechanism that automatically switches between open and closed positions based on insertion or removal, ensuring fluff is intercepted and separated from the drying airflow, and allows for easy cleaning and storage of collected fluff.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a filter is installed to separate fluff from drying airflow, then the reliability of the drying circuit is improved, but the filter requires periodic cleaning which reduces ease of operation
Solution Approach 1:
The rotatable flap mechanism automatically closes when the filter is removed from the slot, preventing fluff from escaping and obstructing the drying circuit. This self-closing action eliminates the need for manual intervention to ensure proper closure, allowing users to easily remove and clean filters without risking circuit obstruction.
2Ease of operation
If automatic fluff removal systems are implemented, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The invention extracts the fluff separation function into a dedicated filter assembly that can be easily removed and cleaned by the user. Instead of implementing a complex automatic removal system, the filter captures fluff and allows users to simply remove and clean the filter, achieving ease of operation without additional complexity.
Solution Approach 2:
The filter assembly acts as a disposable or easily replaceable component that captures fluff during operation. Rather than designing a complex permanent automatic removal system, the invention uses a simple, low-cost filter that users can periodically remove and clean, maintaining ease of operation while avoiding device complexity.
3Productivity
If the filter is always housed in the slot for continuous operation, then productivity is improved, but accessibility for cleaning is reduced
Solution Approach 1:
The filter assembly is designed to be dynamically positionable between a housed state (when in use) and a removed state (when being cleaned). The rotatable flap mechanism adapts to both positions, automatically closing when removed to maintain circuit integrity. This dynamic design allows continuous operation during use while providing easy accessibility during maintenance.

Function Achieved in This Case
The solution enhances the reliability and safety of the drying circuit by automatically managing fluff separation, reducing user intervention and preventing circuit obstruction, while maintaining ergonomic comfort and compatibility with heat pump systems.
Implementation Method 1
The rotatable flap comprising an end portion having a rounded profile and configured to cooperate with a bulge positioned on the machine for drying laundry. The bulge comprising a rounded profile conjugated to the rounded profile of the end portion of the rotatable flap profile in order to act as a member of a cam coupling between the bulge and the end portion.

AI summary
A filter assembly configured for being used in combination with a machine for drying laundry is disclosed. The filter assembly comprises a frame, a duct defined in the frame configured for being passed through by an airflow, an inlet section configured for allowing the airflow to have access to the duct and an outlet section configured for allowing the airflow to leave the duct. The filter assembly comprises a filter configured for intercepting the airflow and for separating from the airflow possible solid particles carried by the airflow, the filter acting between the inlet section and the outlet section and storage configured for storing the solid particles separated from the airflow.
