<p>PROBLEM TO BE SOLVED: Not only to prevent the waste of washing water but also to improve the degree of washing by performing washing for optimum time for washing and the number of times of rinsing while applying a conduction degree sensor for sensing whether a detergent is used or not, the amount of put-in detergents and the degree of contamination at the time of washing. SOLUTION: On the bottom face of a spinning tub 9, a conduction degree sensor 75 is provided for sensing the conduction degree of washing water to be changed at the time of washing and rinsing processes. This conduction degree sensor 75 is a sensor for detecting the amount of ions contained in water, designs two stainless electrode plates in contact with water, detects the amount of contained ions flowing between these two electrode plates and selects a washing method such as the optimum time for washing and the number of times of rinsing. Then, a control part is a microcomputer for controlling the operation of an entire washing machine corresponding to an operating instruction signal inputted by an operation manipulating part, senses the amount of residual detergents corresponding to the conduction degree of washing water to be changed at the time of washing and rinsing processes and controls the washing method such as the optimum time for washing and the number of times of rinsing.</p> |
