Washer Tub Inflow Layout to Prevent Laundry Port Clogging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses face issues with clogging of inflow and communication ports due to laundry, leading to poor sanitation and corrosion, as these ports are often positioned to face the drum introduction port, causing bubbles and foreign substances to be discharged incorrectly.
Innovation Solution
The apparatus redesigns the inflow and communication ports to be positioned outside the drum introduction port, using inclined and protruding structures to prevent clogging and ensure proper water supply and drainage, while maintaining the ports' functionality and sanitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inflow portion is positioned to face the drum introduction port, then water supply function is achieved, but the inflow portion becomes clogged by introduced laundry
Solution Approach 1:
The inflow portion is extracted from the drum introduction port area and repositioned to the tub rear side, separating the water supply function from the laundry introduction path to prevent clogging while maintaining water supply reliability
2Reliability
If the communication connection portion is positioned to face the drum introduction port, then pressure equalization function is achieved, but the communication connection portion becomes clogged by introduced laundry
Solution Approach 1:
The communication connection portion is extracted from the drum introduction port area and repositioned to the tub rear side, separating the pressure equalization function from the laundry introduction path to prevent clogging while maintaining functional reliability
3Stress or pressure
If bubbles flow through the inflow portion to the outside, then pressure release occurs, but sanitation deteriorates and corrosion occurs
Solution Approach 1:
The communication connection portion acts as an intermediary pathway for pressure equalization, allowing bubbles to be released through a dedicated route that prevents direct contact with the inflow portion, thereby maintaining sanitation and preventing corrosion
