Abstract
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.
