Laundry Rinsing Arrangement With Detachable Siphon Partition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machine designs face challenges in achieving a compact construction with effective ventilation and simplified production, while preventing unintentional wetting of laundry due to vibrations and pressure fluctuations, which often result in wetting of spun laundry.
Innovation Solution
A flushing arrangement with a detachable partition wall forming a siphon between the outlet connection and water intake trough, combined with a vapor barrier system in the inlet line, ensures efficient ventilation and condensation, and a dual overflow system to prevent liquid from escaping during vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a one-piece lower part with integrated siphon is produced via injection molding, then manufacturing precision and reliability are improved, but device complexity and production difficulty increase significantly
Solution Approach 1:
The siphon structure is divided into separate components: a partition wall element that is attached to the lower part rather than being integrated through complex injection molding. This segmentation simplifies manufacturing while maintaining the siphon's functional integrity and reliability.
2Device complexity
If the water-receiving trough is designed with a single overflow outlet, then device complexity is reduced, but reliability decreases due to unintentional wetting during vibrations and pressure fluctuations
Solution Approach 1:
The first overflow outlet is positioned at a higher level to prevent liquid from escaping during vibrations and pressure fluctuations before they can cause harmful effects. This preliminary protective measure ensures that even under dynamic conditions, laundry remains dry while maintaining a relatively simple outlet structure.
3Productivity
If a compact flushing arrangement design is implemented, then productivity and space utilization are improved, but manufacturing precision requirements increase due to tight tolerances
Solution Approach 1:
By dividing the lower part into separable components (main body and partition wall element), the design achieves compact dimensions while allowing independent manufacturing and assembly of parts with standard tolerances, avoiding the need for tight tolerances that would result from integrating all features into a single complex component.
