Dryer Filter Assembly With Sliding Lint Access and Cleaning Nozzle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry dryers with lint filter cleaning devices face challenges in user accessibility and maintenance, as the lint filter and cleaning device are often located deep within the cabinet, requiring disassembly of the side cabinet for replacement or inspection.
Innovation Solution
A laundry dryer design featuring a filter assembly with a sliding lint filter unit and a cleaning nozzle, allowing for easy detachment and maintenance of the lint filter, with a configuration that includes a blocking filter and filter housing for improved accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the lint filter and cleaning device are disposed in the vicinity of a central portion of the inside of a cabinet, then the drying air circulation is improved, but the accessibility for replacement and maintenance deteriorates
Solution Approach 1:
The filter assembly is divided into separable components: the lint filter can be independently removed from the case, and the cleaning device can be accessed separately. This segmentation allows the lint filter to be positioned optimally for drying air circulation while maintaining ease of access for replacement and maintenance.
2Device complexity
If the lint filter and cleaning device are located at a deep portion within the cabinet, then the structural integration is improved, but the ease of maintenance deteriorates
Solution Approach 1:
The lint filter is extracted as a removable component from the case, allowing it to be easily removed and replaced without disassembling the entire filter assembly or side cabinet. The cleaning device is also designed to be accessible through the removed lint filter, enabling easy maintenance while maintaining structural integration.
3Ease of operation
If the lint filter is automatically cleaned, then the user convenience is improved, but the accessibility for checking cleaning device conditions deteriorates
Solution Approach 1:
The lint filter serves as an intermediary component that provides access to the cleaning device. By removing the lint filter, users can directly access and check the cleaning device conditions. This design maintains the automatic cleaning function for user convenience while enabling easy access for maintenance and inspection.
