Abstract (en)
[origin: EP2455529A1] A washing machine includes a cabinet, an outer tank, an inner tank, a circulation tube, and a circulation pump. The outer tank is held in the cabinet. The inner tank is rotatably mounted in the outer tank so as to accommodate and stir laundry. The circulation tube draws washing water kept in the outer tank and returns it to the outer tank. The circulation pump is located at some midpoint in the circulation tube so as to circulate the washing water. The washing machine further includes, at some midpoint in the circulation tube, a washing water-condition detector for detecting the condition of the washing water. This structure ensures the amount of washing water circulating through the washing water-condition detector, without depending on the operation of the inner tank. Thus, the washing machine can detect the degree of contamination of washing water with high accuracy while maintaining its washing efficiency.
