Clothes Dryer Filter Cover Coupling for Assembly Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensing type clothes dryers lack a mechanism to confirm if the filter unit is properly assembled, leading to potential inefficiencies and increased maintenance costs due to foreign substances like lint and heat loss.
Innovation Solution
A clothes dryer design featuring a filter unit and filter cover with a coupling structure that ensures the filter cover is not assembled unless the filter unit is correctly mounted, utilizing a first and second coupling member and a rotation member to visually indicate assembly status and prevent accidental removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If the filter unit is made detachable for cleaning, then ease of maintenance is improved, but reliability deteriorates because users may forget to reassemble it
Solution Approach 1:
The filter cover incorporates a visual feedback mechanism through its coupling structure with the filter unit. When the filter unit is properly reassembled, the filter cover can be closed and latched, providing clear visual confirmation that the filter is in place. This feedback loop ensures users know whether the filter has been correctly reinstalled, preventing operation with a missing filter while maintaining easy detachability for cleaning.
2Device complexity
If no assembly confirmation mechanism is provided, then device complexity is reduced, but harmful factors increase due to heat loss and foreign substance leakage
Solution Approach 1:
The patent merges the assembly confirmation function with the existing filter cover structure. The filter cover serves dual purposes: it protects the filter unit and simultaneously provides visual confirmation of proper assembly through its coupling mechanism. This integration adds minimal complexity while effectively preventing heat loss and foreign substance leakage that would occur if the filter were missing or improperly installed.
3Object-affected harmful factors
If the filter cover is always assembled, then harmful factors are prevented, but ease of operation deteriorates because users cannot access the filter for cleaning
Solution Approach 1:
The filter cover is designed with dynamic functionality, allowing it to be opened for filter access and closed for protection. The coupling structure between the filter cover and filter unit enables easy attachment and detachment, facilitating regular cleaning while ensuring the cover is properly reassembled. This dynamic design balances accessibility for maintenance with protection against harmful factors during operation.

AI summary
A clothes dryer with a filter unit and a filter cover having a coupling structure corresponding to each other. The clothes dryer includes a body, a drum installed inside the body, a drying unit configured to dry air passed through the drum, a filter unit disposed on the drying unit and detachably installed on the body, a filter cover fixed by provided with one side thereof being installed on the body and the other side thereof being coupled to the filter unit. When the filter unit is not assembled, a user may notice the filter unit not being assembled due to the filter unit and the filter cover, both of which are provided with a coupling structure corresponding to each other.
