Impact of Water Hardness in Instinctive Laundry System Based on Fuzzy Logic Controller

Abstract

In this paper, we discuss the effects of water types and temperature in automatic washing machine. The automatic washing machines are being used in hard water areas void of useful results because machines could not detect the type of water. Hard water consumes more detergent and washing time for laundry. The proposition of the paper is that the soft water and high temperature should be used in washing machines, it will not only reduce the quantity of detergent but also have positive effects on economy and fabrics. In this way, energy and washing time can be saved. The results are verified by TOPSIS technique of MCDM. The pretending results and the actions of aforesaid device have been done by using MATLABs fuzzy logic toolbox.
