    • A foam sensor of a drum washing machine is constructed such that a pair of temperature electrode terminals and a foam electrode terminal are supplied with electricity by a single connector, and thus is able to sense an electrical connection by a signal change of the temperature electrode terminals, in a case where electrical connection of the foam electrode terminal is cut off, thereby preventing a false sensing of foam generation caused by electrical short-circuiting of the foam electrode terminal. Furthermore, the foam electrode terminal is provided integral with the connector, and the temperature sensor portion has a thermistor for sensing a temperature of washing water and temperature electrode terminals inserted into the connector, the thermistor and the temperature electrode terminals being connected by a cord, which makes installation easier.
    • 滚筒洗衣机的泡沫传感器被构造成使得一对温度电极端子和泡沫电极端子被单个连接器供电,从而能够通过温度电极端子的信号变化感测电气连接 在泡沫电极端子的电连接被切断的情况下,从而防止由泡沫电极端子的电短路引起的泡沫产生的错误检测。 此外,泡沫电极端子与连接器一体设置,温度传感器部分具有用于感测插入连接器中的洗涤水和温度电极端子的温度的热敏电阻,热敏电阻和温度电极端子通过电线连接, 这使得安装更容易。
