Construction of a Virtual Washing Machine

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.
