    摘要： The present invention relates to a method and device for detecting detergent present in process water in a household appliance for washing and rinsing goods. To this end, turbidity of the process water is measured (S101), which measured turbidity signal indicates the presence of detergent in the process water. Subsequently noise level of the measured turbidity signal is determined (S102), which noise level indicates type of detergent present in the process water.
    Field tests have shown that detection of the particular type of detergent used in a household appliance for washing and rinsing goods, i.e. whether distinction can be made between liquid/gel or tablet/powder detergent disposed in water for washing the goods, is difficult by means of analyzing the measured level of turbidity, which typically is measured by a turbidity sensor. Advantageously, by measuring the turbidity of the water and subsequently analysing the measured turbidity signal to determine noise levels in the measured turbidity signal output from the turbidity sensor, it is possible to distinguish between liquid/gel detergent on the one hand and tablet/powder detergent on the other.
