AI Technical Summary

⚠Technical Problem

Existing laundry appliances struggle to effectively separate and collect micro-sized particles, such as microfibers, from process fluids due to their ability to pass through conventional filtration mechanisms, leading to environmental contamination and reduced appliance performance.

⚗Method used

A micro-particle filtration system is integrated into laundry appliances, featuring a dynamic filter with a rotor generating centrifugal flow and a hydrophobic material to capture micro-sized particles, which separates and collects them in a removable collection chamber.

🎯Benefits of technology

The system efficiently captures and collects micro-sized particles, maintaining appliance performance by preventing their passage through the filtration system, allowing for continuous operation and easy disposal or recycling of collected particles.

Abstract

A laundry appliance includes a tub that is positioned within an outer cabinet. A processing space is defined within the tub. A fluid path delivers a process fluid through the tub for treating articles within the processing space. A micro-particle filter is positioned within the fluid path. The micro-particle filter separates micro-sized particles from the process fluid. A secondary flow mechanism delivers the micro-sized particles from the micro-particle filter to a removable collection chamber.
