Washer Door Rinsing Using Centrifugal Water Ejection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses with minimized volume face issues where impurities and bubbles generated during washing remain on the door, leading to reduced washing efficiency and potential user confusion about completion of washing, and require additional components that may be prone to pressure-related failures.
Innovation Solution
The apparatus incorporates a supply aperture for water in the tub cover, an ejection unit to direct water to the door and drum using centrifugal force, and a pressure reduction unit to manage water pressure, ensuring effective removal of impurities and bubbles from the door and drum surfaces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the volume of the laundry treatment apparatus is minimized, then the distance between the introduction aperture and the upper end of the drum is reduced, but impurities and bubbles remain on the door
Solution Approach 1:
The patent extracts and removes bubbles and impurities from the washing water using a bubble removal unit that separates these harmful factors from the main washing process, preventing them from adhering to the door while maintaining the minimized apparatus volume
Solution Approach 2:
The patent introduces water flow as an intermediary substance that flushes the door surface to remove adhered bubbles and impurities, using the existing washing water as a cleaning medium rather than requiring separate removal mechanisms
2Object-affected harmful factors
If additional parts and flow channels are provided to remove impurities from the door, then impurity removal capability is improved, but device complexity increases
Solution Approach 1:
The patent makes the washing water serve multiple functions: it performs both the primary washing of laundry and the secondary cleaning of the door surface, eliminating the need for separate impurity removal systems
Solution Approach 2:
The system uses its own washing water to clean the door and remove impurities, making the apparatus self-maintaining without requiring additional external systems or components
3Object-affected harmful factors
If the pressure of wash water in the additional flow channel is excessively increased, then impurity removal effectiveness is improved, but the flow channel may be broken causing leakage
Solution Approach 1:
The patent applies water flow at sufficient but not excessive pressure to the door surface, using just enough force to remove impurities without damaging the flow channel structure
Solution Approach 2:
The system design anticipates pressure-related damage by using the existing robust water supply system to provide controlled pressure that is sufficient for cleaning but built within safe operational limits to prevent channel breakage
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
Prevents impurities and bubbles from sticking to the door, ensures complete washing without user doubt, maintains washing efficiency, and prevents pressure-related issues in additional flow channels, thereby enhancing the overall performance of the laundry treatment process.
