摘要：PROBLEM TO BE SOLVED: To provide a drum washing machine having a stable washing effect by accurately detecting turbidity. SOLUTION: The drum washing machine includes: a rotation drum 37 formed in the shape of a bottomed cylinder; a water tub 36 having the rotation drum 37 inside: a motor 38 for driving a rotation drum 37; control means 53 which controls a washing step, a rinsing step, or the like by controlling the motor 38 or the like; and a circulation system water path 47 for circulating washing water in the water tub 36 by a circulation pump 48 communicating with a circulation path 49 connecting to the water tub 36. The circulation system water path 47 causes the washing water to be discharged from a spraying port 70 in front of the water tub 36 into the rotation drum 37. In the piping side wall in the vicinity of the lowest point of the circulation path 49 having the circulation pump 48, an optical sensor 57 detecting the turbidity and an electrode sensor 58 capable of measuring an electric conductivity are constituted to be adjacent in a nearly horizontal manner. Thus, it is possible to accurately detect the turbidity of the washing water in the washing tub in a stable manner without requiring a complicated structure. COPYRIGHT: (C)2011,JPO&INPIT
