Spring-Loaded Rinse Container Sealing for Leak-Resistant Dryers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rinsing containers for laundry drying devices face issues with leakages and inefficient cleaning due to low liquid pressure, especially when the filling level is low, leading to incomplete sealing and potential leaks, which increases the complexity and cost of the arrangement.
Innovation Solution
A rinsing container with a closure part featuring a sealing head connected via a spring element that requires an opening force exceeding the spring's pressing force, ensuring secure sealing independent of the fill level, and an actuating unit that directly operates the sealing head for reliable and efficient rinsing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a closure plate is used to close the outlet opening, then the structure is simple, but the sealing is unreliable when liquid pressure is low
Solution Approach 1:
The closure part uses a dynamic sealing mechanism where a sealing head with a sealing element can move relative to the outlet opening. The spring element provides continuous pressing force to maintain sealing contact, allowing the seal to adapt to varying liquid pressure conditions and ensure reliable sealing even when pressure is low.
Solution Approach 2:
A sealing element acts as an intermediary between the closure part and the outlet opening. This sealing element (such as a sealing ring or gasket) mediates the contact between moving and stationary parts, ensuring reliable sealing while allowing for relative movement and pressure variations.
2Quantity of substance
If liquid pressure is low, then the filling level is low, but the sealing becomes incomplete leading to leaks
Solution Approach 1:
The spring element acts as a counterweight to the low liquid pressure. It provides a pressing force that counteracts the reduced pressure force when the filling level is low, ensuring the sealing element maintains sufficient contact pressure with the outlet opening to prevent leaks.
Solution Approach 2:
The spring element pre-presses the sealing element against the outlet opening before liquid pressure acts on it. This preliminary action ensures the seal is already in contact and properly positioned, so when liquid pressure (even low pressure) acts on the closure plate, the sealing is maintained without gaps.
3Force
If a guided through the floor poppet valve is used, then the opening force is reduced, but leakage security decreases and assembly complexity increases
Solution Approach 1:
The closure part is segmented into distinct functional elements: a closure plate for blocking the opening, a sealing head with a sealing element for creating the seal, and a spring element for providing pressing force. This segmentation allows each element to perform its specific function optimally while maintaining simple assembly.
Solution Approach 2:
The spring element automatically provides the necessary pressing force to the sealing element without requiring external actuation or complex guiding mechanisms. The system is self-regulating, where the spring force adapts to maintain sealing contact, eliminating the need for guided through-floor mechanisms and their associated leakage risks.
