Washer Tub Inflow Layout to Prevent Drum-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 improperly.
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 a sanitary state by preventing foreign substances from entering these areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the inflow portion is provided at the tub to face the drum introduction port, then water supply function is achieved, but the inflow portion is clogged by laundry
Solution Approach 1:
The inflow portion is extracted from the drum introduction port area and relocated to a separate position on the tub. This separation removes the harmful interaction between laundry entering through the drum introduction port and the water supply function, preventing clogging while maintaining reliable water supply.
2Reliability
If the communication hole is provided at the tub to face the drum introduction port, then pressure equalization function is achieved, but the communication hole is clogged by laundry
Solution Approach 1:
The communication hole is extracted from the drum introduction port area and repositioned to a separate location on the tub. This spatial separation ensures that laundry entering through the drum introduction port cannot block the communication hole, maintaining pressure equalization function while preventing clogging.
3Reliability
If the inflow portion faces the drum introduction port, then water supply is enabled, but bubbles and foreign substances discharge improperly causing sanitation deterioration
Solution Approach 1:
The inflow portion is relocated away from the drum introduction port to a position where it does not face the incoming laundry stream. This separation prevents bubbles and foreign substances generated during laundry introduction from contaminating the water supply system, maintaining sanitation while preserving water supply function.
4Reliability
If the communication hole faces the drum introduction port, then pressure equalization is enabled, but bubbles and foreign substances flow through causing corrosion
Solution Approach 1:
The communication hole is repositioned to a location separate from the drum introduction port. This spatial separation prevents bubbles and foreign substances generated during laundry introduction from flowing through the communication hole, eliminating the corrosion risk while maintaining pressure equalization function.

AI summary
A laundry treatment apparatus includes a cabinet with an entrance, a drawer provided to be withdrawable from the cabinet through the entrance, a tub provided inside the drawer to provide a space for storing water, a height of the tub being smaller than a width of the tub, a water supply unit communicating with the tub to supply water, and a drum including a drum body rotatably provided inside the tub and a drum introduction port provided at an upper portion of the drum body and opened to allow laundry to be introduced. The tub includes a tub body, a tub cover, a tub introduction port, and an inflow portion provided at any one of the tub cover and the tub body. The inflow portion is disposed at an outer side of the drum introduction port to prevent the inflow portion from facing the drum introduction port.
