A laundry dryer comprising a filter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensation type laundry dryers face inefficiencies in drying effectiveness due to unfiltered condensate water, which can lead to clogging and reduced performance.
Innovation Solution
Incorporation of a water filter at the tank outlet to filter condensate water before it is reused in the air circulation system, preventing clogging and enhancing cleaning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If condensate water is reused in the air circulation system without filtration, then the system operates continuously without maintenance interruptions, but clogging occurs reducing drying effectiveness
Solution Approach 1:
A water filter is introduced as an intermediary component between the condensate tank and the air circulation system. The filter housing with detachable filter element captures lint and debris from condensate water before it is pumped back to the heat exchanger, preventing clogging while maintaining system continuity and drying effectiveness.
2Productivity
If a water filter is installed at the tank outlet, then clogging is prevented improving drying effectiveness, but the device complexity increases
Solution Approach 1:
The filtration system is segmented into a filter housing and a detachable filter element. This segmentation allows the filter element to be easily removed and cleaned without disassembling the entire water circulation system, maintaining productivity while managing device complexity through modular design.
Solution Approach 2:
The filter element acts as an intermediary between the condensate tank and pump, intercepting debris that would otherwise cause clogging. This protects the more complex pumping and heating components while adding minimal complexity through a simple filtration stage.
3Device complexity
If the water filter is integrated into the tank structure, then the device complexity is reduced, but the ease of operation for filter maintenance is worsened
Solution Approach 1:
The filter housing serves as an intermediary structure that provides easy access to the filter element through a removable cover. This design simplifies maintenance operations by allowing users to clean the filter without draining the tank or disassembling complex components, improving ease of operation while maintaining integrated design benefits.

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 filtered water improves drying effectiveness by maintaining system cleanliness and preventing errors like a full tank due to clogging, while allowing easy maintenance of the water filter.
Implementation Method 1
a water filter that provides the filtering of the water delivered to the water conduit through the outlet
Implementation Method 2
The spraying device sprays the water onto the condenser or the air filter and thus cleans these components
Implementation Method 3
a condenser that provides the dehumidification of the drying processing air
