Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dryers face issues with lint accumulation on lint filters, leading to air flow obstruction, increased power consumption, and potential fire hazards due to lint being introduced into fan motors or combustion devices, and current methods for cleaning lint filters can cause blockages in drain pumps.
Innovation Solution
A dryer design featuring a lint filter assembly with a partition rib structure that divides the filter into multiple blocks, allowing for the separation of lint into smaller lumps, and a cleaning device that uses water to remove lint with a control valve to manage the introduction of lint into the drain pump, minimizing blockages and preventing damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water is sprayed through nozzles to remove lint from the lint filter assembly, then lint is removed from the filter, but large lint lumps are generated that can block the drain pump inlet or outlet
Solution Approach 1:
The lint filter assembly is divided into multiple filtering blocks separated by partition ribs. When water is sprayed, lint is removed from each block separately, preventing the formation of large lint lumps that could block the drain pump. The segmentation ensures lint is dispersed into smaller portions throughout the cleaning process.
2Object-affected harmful factors
If lint is deposited on the lint filter assembly, then lint filtration is effective, but air flow is obstructed and power consumption increases
Solution Approach 1:
The lint filter assembly is segmented into multiple filtering blocks that can be independently cleaned. This segmentation allows for more efficient lint removal and reduces air flow obstruction, thereby decreasing the power consumption of the blower fan while maintaining effective lint filtration.
Solution Approach 2:
The lint filter assembly is designed to be automatically cleaned by water spraying through nozzles. This self-cleaning function removes lint accumulation that would otherwise obstruct air flow and increase power consumption, eliminating the need for manual intervention while maintaining system efficiency.
3Productivity
If lint is introduced into the fan motor or combustion device, then drying function is maintained, but fire hazard increases
Solution Approach 1:
The partition ribs extract and separate lint from the air flow path before it can reach the fan motor or combustion device. By taking lint out of the circulation system through the segmented filter structure, the design maintains drying function while eliminating the fire hazard of lint introduction to sensitive components.
4Ease of manufacture
If the lint filter assembly is made as a single mesh structure, then manufacturing is simple, but lint deposition forms large lumps that block drain pump
Solution Approach 1:
The lint filter assembly is segmented into multiple filtering blocks separated by partition ribs. This segmentation prevents lint from forming large deposition lumps across the entire filter surface, instead distributing lint collection across smaller sections. This maintains manufacturing simplicity while significantly reducing drain pump blockage risk.
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 partitioned lint filter design reduces lint lump size and frequency, minimizing blockages in the drain pump and improving dryer performance by allowing for staggered introduction of small lint lumps, thus preventing pump overload and maintaining efficient operation.
Implementation Method 1
a heating unit disposed in any position of the suction passage to heat the air introduced into the suction passage at a high temperature
Implementation Method 2
a blower mounted on one position of the exhaust passage to forcibly blow the air within the drying drum
Implementation Method 3
water is sprayed through nozzles disposed at front and rear sides of the lint filter assembly to remove lint deposited on the lint filter assembly
