Abstract

In the past years some researches were conducted to model laundry washing in the automatic washing machine. The most studies, however, were focused to some aspects of the automatic laundry washing (e. g. spinning cycle) and not on the washing process as whole. In this paper a model of a washing machine is presented that is based on measured data of 9 different washing machines with rated capacity between 5 kg and 11 kg, which are produced by six different manufacturers. The proposed approach is based on multiple linear regression analysis to extract the systematic, model independent behavior of washing machines and is used to calculate the consumption of the water, energy and detergent in dependence of the rated capacity, washing temperature, duration of the main wash, load size and washing performance.

Kurzfassung

In den letzten Jahren begannen einige Forscher damit, den Waschvorgang in automatischen Waschmaschinen zu modellieren. Die meisten Untersuchungen befassten sich mit ausgewählten Aspekten der Maschinenwäsche (z. B. mit dem Spülvorgang) und nicht mit dem gesamten Waschprozess. Diese Untersuchung präsentiert ein Modell einer Waschmaschine, das auf den Messdaten von 9 verschiedenen Waschmaschinen mit Beladungskapazitäten von 5 kg bis 11 kg basiert. Die Maschinen stammten von sechs verschiedenen Herstellern. Der vorgestellte Ansatz basiert auf der multiplen linearen Regressionsanalyse, um das systematische, modellunabhängige Verhalten der Waschmaschinen herauszuarbeiten. Es wird eingesetzt, um den Wasser-, Energie- und Waschmittelverbrauch in Abhängigkeit von der Nennkapazität, der Waschtemperatur, der Dauer der Hauptwäsche, der Beladungsgröße und der Waschleistung zu berechnen.

Dr. Emir Lasic, University of Bonn

In 2009 Emir Lasic completed his diploma degree at the University of Bonn with main focus on household science. In 2014, Emir Lasic completed his doctoral studies at the Household Science Section of the Institute of Agriculture Engineering of the University of Bonn. His studies involve the research in the field of the use of sustainable washing technologies, as well as its acceptance in households.

Prof. Dr. Rainer Stamminger, University of Bonn

After 17 years of practical experience in the development of washing machines and dishwasher with AEG Hausgeräte, Germany Rainer Stamminger was promoted in 2002 as professor for appliance and process engineering at University of Bonn. Main areas of research at University are consumer behaviour of homework with and without using appliances, new products or features, smart appliances, robots for household application and questions of sustainability of housekeeping.

Christian Nitsch studied Chemistry in Düsseldorf (HHU) and London (King's College). He did his PhD thesis at MPI for Chemical Energy Conversion in Mülheim. In 1989 he joined Henkel. He lead the global dishwashing detergent development for many years. Since 2010 he is responsible for the applied technology department in Henkel's global R&D.

Arnd Kessler graduated from Georg-Simon-Ohm University of applied Sciences in Nuremberg in Chemical Engineering (Dipl.-Ing.). In 1998 he joined Henkel's corporate research team. From 2000 until 2011 he worked as a product developer for automatic dishwashing detergents. Since 2011 Mr. Kessler heads Henkel's global appliance & technology team.
