Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machines face issues with thread scraps accumulating in filters, leading to reduced filtering efficiency, potential bacterial growth, and environmental pollution, as they require manual cleaning and often fail to capture fine debris, causing ecological and health concerns.
Innovation Solution
A washing machine design incorporating a filtering device with a discharge outlet and a recovery device to collect filtered impurities, using a circulation filtering pipeline and control valves to manage water flow, allowing for self-cleaning and direct impurity collection without manual intervention, and integrating a three-way structure for simultaneous circulation filtering and drainage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the filter holes aperture is set large, then the filter can be cleaned easily and avoid blockage, but fine thread scraps cannot be filtered effectively
Solution Approach 1:
The filter system is segmented into multiple filtering devices with different aperture sizes. The first filtering device has larger aperture for easy cleaning, while the second filtering device has smaller aperture for fine filtration. This segmentation allows each component to specialize in one function, resolving the contradiction between ease of cleaning and filtering precision.
2Reliability
If manual cleaning is required, then the filter can be maintained, but user operation becomes inconvenient
Solution Approach 1:
The system implements self-service through automatic cleaning mechanisms. The washing machine's water circulation system automatically flushes the filtering devices during washing cycles, and the filter cleaning device can automatically remove accumulated impurities without user intervention. This maintains filter reliability while eliminating manual operation requirements.
3Device complexity
If filtered impurities are discharged with drainage water, then the drainage system is simple, but ecological pollution occurs
Solution Approach 1:
The system extracts filtered impurities from the drainage flow by introducing them into a separate collection container through the impurity discharging device. This separation removes harmful substances from the ecological cycle while maintaining a relatively simple drainage system structure, resolving the contradiction between system simplicity and environmental protection.
4Ease of operation
If the filter is not cleaned regularly, then operation is simple, but filtering efficiency decreases and bacteria breed
Solution Approach 1:
The system ensures continuous filtering efficiency through automated maintenance actions. The water circulation system continuously flushes the filters during washing, and the impurity removal mechanism periodically clears accumulated debris. This continuous maintenance action prevents efficiency degradation without requiring complex user operations.

AI summary
A washing machine and a control method thereof, the washing machine includes: a water container; a filtering device, communicating with the water container and configured to filter the water in the water container, the filtering device is provided with a discharge outlet for discharging filtered impurities outward; and a recovery device, separately arranged with the filtering device and communicating with the discharge outlet of the filtering device for collecting the discharged filtered impurities. The filtered impurities are collected by setting a recovery device, so that the filtered impurities are not directly discharged along with the drainage water of the washing machine. At the same time, the recovery device and the filtering device are separately arranged, and the filtered impurities are discharged into the recovery device without being accumulated in the filtering device, thus avoiding the influence on the filtering efficiency.
