At a time of normal use, the drinking water stored in the cold water tank 54 is cooled by a Peltier element 57. At a time of sterilization, polarity of the Peltier element 57 is inverted and the polarity-inverted Peltier element 57 heats the drinking water stored in the cold water tank. With such a configuration, that is a simpler configuration, a normal temperature portion or a cooling portion can be sterilized.</p> |
