AI Technical Summary

Technical Problem

Traditional washing machines discharge significant amounts of fibers into waste water, contributing to environmental pollution, and their filters clog quickly due to fiber accumulation, necessitating frequent cleaning or replacement.

Method used

A washing machine with a filtering member featuring a sponge-like additional filter positioned at a distance from the water inlet, inclined in the receptacle, and supported by a frame, which retains fibers effectively while allowing water flow, using a porous material with varying pore sizes and antimicrobial properties to prevent clogging.

Benefits of technology

The solution increases filtration performance and extends the economic life of the filter by reducing fiber accumulation on the mesh filter, enhancing the retention of larger fibers and preventing microbial contamination.
