AI Technical Summary
Technical Problem
Existing washing machines fail to effectively filter out lint and microplastics from drainage water, leading to environmental pollution and inconvenience in manual filter cleaning, with residual sewage issues and bacterial growth.
Method used
A dual filtration system with a first and second waterway, utilizing a pump to drive water through filters and a sewage receiving device, combined with a self-cleaning mechanism and gravity-driven discharge, to capture and remove impurities without additional power sources.
Benefits of technology
The system effectively reduces microplastic discharge, prevents residual sewage, and ensures efficient filtration without manual intervention, maintaining apparatus functionality and environmental safety.

Abstract
A filtering system includes: a first filtration waterway, in which water is driven to be drained out of a water holding tub of the washing apparatus at least sequentially through a filter and a filtering device by a pump; a second filtration waterway, in which water flows at least sequentially through a sewage receiving device and the pump from the filtering device, and then is drained out of the washing apparatus. In the present application, the filtering system of the washing apparatus of the present application has two filtration waterways through which water is discharged out after being filtered, so that the filtration impurities in water can be fully removed, and the content of filtration impurities in water discharging from the washing apparatus can be reduced.
