In addition, a display means 6 indicates that hot water is under supply by the outputs of the timer 5 and 7. As a result, the display means 6 not only indicates that hot water is under supply during the hot water is being supplied but also continue the indication until all the hot water left in the basket for extracting tea or the like is completely delivered from a hot water supplying device, resulting in enabling to give warning to a user on getting scalded by touching a container under supply during the delivery of hot water and, in addition, to use the titled device under clean conditions, because no hot water drop occurs. |
