Washing Machine Filter Cover Assembly to Protect Net and Laundry
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional foreign materials filtering apparatuses in washing machines are prone to damage due to friction with laundry and have a risk of the frame detaching from the washing tub, which degrades the appearance and functionality.
Innovation Solution
A foreign materials filtering apparatus with a washing water circulating duct, a filter cover, and a net filter positioned between the duct and the cover, which prevents direct contact with laundry and enhances the appearance by modularizing the filter unit for easy installation and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the filtering net is installed to be exposed to inside of the washing tub, then foreign materials can be filtered from washing water, but the filtering net or laundry may be damaged due to repeated contact and friction
Solution Approach 1:
The filter cover serves as an intermediary component that covers the washing water inlet and supports the net filter, preventing direct contact between the filtering net and laundry while still allowing washing water to pass through for filtration. This mediator structure protects the filtering net from damage by laundry friction.
2Reliability
If the filtering net is installed to be exposed to inside of the washing tub, then foreign materials can be filtered from washing water, but the frame may be detached from the washing tub which causes the entire appearance to be degraded
Solution Approach 1:
The filter cover and net filter are combined into a single integrated assembly that is mounted together on the washing water circulating duct. This merging ensures that both components remain securely attached as one unit, preventing the frame from detaching while maintaining the filtering function.
3Reliability
If the filtering net is installed to be exposed to inside of the washing tub, then foreign materials can be filtered from washing water, but the entire appearance is degraded
Solution Approach 1:
The filter cover acts as a protective cover that obscures the filtering net from view while still allowing washing water to pass through. This intermediary structure improves the appearance by hiding the mesh-like filtering net, creating a more aesthetically pleasing appearance while maintaining the filtering function.
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 damage to the filtering net and laundry, maintains the frame's attachment to the washing tub, and improves the overall appearance and ease of installation of the filtering apparatus.
Implementation Method 1
a net filter disposed between the washing water circulating duct and the filter cover, for filtering foreign materials from washing water introduced through the washing water inlets

AI summary
In a foreign materials filtering apparatus and a washing machine having the same, a filter cover is installed at a washing water circulating duct disposed inside a washing tub, and a net filter is installed at an inner side of the filter cover. Accordingly, the net filter is prevented from directly contacting laundry, thereby preventing the not filter and the laundry from being damaged. Furthermore, since the net filter is covered by the filter cover, the entire appearance is enhanced. Additionally, when the net filter is mounted at the filter cover, the filter unit becomes modularized to be facilitate a detachable mounting.
