Laundry Fabric Classification in Vertical Axis Washing Machines Using Data-Driven Soft Sensors

Marco Maggipinto, Elena Pesavento, Fabio Altinier, Giuliano Zambonin, Alessandro Beghi, Gian Antonio Susto
2019 Energies  
In Vertical Axis Washing Machines (VA-WM), knowing the laundry composition is fundamental to setting the washing cycle properly with positive impact both on energy/water consumption and on washing performance  ...  this reason, we present here a data-driven soft sensor that exploits physical measurements already available on board a commercial VA-WM to provide an estimate of the load typology through a machine-learning-based  ...  For example, in our case, the load weight (from 1 kg to 8 kg) is an important discriminator that highly impacts the amount of water absorbed by the laundry and imposes a hierarchical structure to our problem  ...
