Condensing Passage Fluff Capture Device for Centralized Dryer Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry drying machines face issues with fluff accumulation in the condensing passage, leading to reduced drying efficiency, potential safety risks, and incomplete cleaning, as the fluff accumulates on sensor surfaces and increases air resistance, and current cleaning methods are ineffective for the upper portions of the passage and fan.
Innovation Solution
A fluff capturing device with adjacently disposed grooves and protrusions on the inner wall of the condensing passage, positioned near the inlet, captures fluff effectively and facilitates centralized cleaning, using a water supply channel positioned higher than the capturing device to rinse accumulated fluff during a washing program.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional smooth inner wall is used in the condensing passage, then air flow resistance is low and manufacturing is simple, but fluff accumulates on the inner wall and cannot be effectively captured
Solution Approach 1:
The inner wall of the condensing passage is designed with different local structures: the lower portion has grooves and protrusions for fluff capture, while the upper portion remains smooth for easy rinsing. This local differentiation allows the structure to serve multiple functions - capturing fluff where it accumulates most while maintaining simplicity in areas where fluff is less problematic.
Solution Approach 2:
The condensing passage inner wall is segmented into multiple functional zones using grooves and protrusions. These segments create distinct capture areas that intercept fluff at different positions, preventing it from traveling further into the passage and improving overall capture efficiency without requiring a complete structural overhaul.
2Ease of repair
If water is sprayed into the condensing passage to rinse fluff, then some cleaning is achieved, but only the lower portion is rinsed effectively while the upper portion and fan remain uncleansed
Solution Approach 1:
The fluff capture device is positioned at the lower portion of the condensing passage to intercept and accumulate fluff before it can spread to the upper portions and fan. This preliminary capture action concentrates all fluff in one location, making the subsequent rinsing operation much more effective and comprehensive.
Solution Approach 2:
The fluff capture device extracts and concentrates fluff from the entire condensing passage into a single accumulation point at the lower portion. This extraction allows the rinsing system to focus on one concentrated location rather than attempting to clean scattered fluff throughout the entire passage, significantly improving cleaning coverage.
3Productivity
If the fluff capturing device is positioned at the lower portion of the condensing passage, then centralized capture and rinsing is achieved, but fluff at the upper portion and within the fan cannot be captured
Solution Approach 1:
The fluff capture device performs preliminary interception of fluff at the lower portion of the condensing passage, capturing the majority of fluff before it can travel to the fan and heating channel. This preliminary action at a strategic location prevents fluff from reaching critical components, addressing the harmful effects before they occur.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution improves cleaning efficiency by preventing fluff from entering other areas, reducing air resistance, and ensuring comprehensive rinsing of the condensing passage, enhancing the safety and efficiency of the drying process by capturing and removing fluff effectively.
Implementation Method 1

AI summary
A laundry drying machine is disclosed, including a drying compartment and a condensing passage in fluid communication with the drying compartment. Along an air flowing direction, the condensing passage has an inlet connected to the drying compartment and an outlet at a position higher than that of the inlet. A fluff capturing device is disposed on an inner wall of the condensing passage. The fluff capturing device includes multiple adjacently disposed grooves and/or protrusions. Fluff entering the condensing passage is captured by the fluff capturing device, so that the fluff is prevented from being attached to another area of the condensing passage, or from entering another area of an airflow channel. The fluff may be cleaned in a centralized manner after accumulating on the capturing device, improving the cleaning efficiency.
