<p>A washing machine in which metal ions exhibiting an antibacterial action can be added to water with a target concentration regardless of the water quality or the water temperature. A pair of metallic electrodes are applied intermittently with a voltage and metal ions are eluted alternately from one and the other electrodes. Water quality and water temperature are then detected from an applying voltage required for feeding a specified current and, depending on the detection results, a current being fed between the electrodes, an elution time of metal ions (T4), a voltage applying time (T2) or a voltage application suspension time (T3) is altered thus adjusting elution quantity of metal ions.</p> |
