PURPOSE:To provide the bath heating device having bathroom drying function by one series of hot-water pipeline, one set of heat exchanger for heating, one set of outer casing and the like by a method wherein a fan for circulating air in the bathroom is provided above the water level of a bathtub, the delivery port thereof is connected to the outer casing and the suction port thereof is connected to the inside of the bathroom respectively while a water level detector, having the operating point thereof at a position equal to or lower than a circulating pipe for heating the bath, is provided in the outer casing. CONSTITUTION:When water in the bathtub 1 is discharged, water in the outer casing 2 is discharged through bath circulating pipes 3, 5 and air around the heat exchanger 4 for heating is communicated with the air in the bathroom 14. Then, the water level detector 10 detects that the bathtub is emptied and the fan 11 for circulating air in the bathroom starts operation. The air in the bathtub 1 enters into the outer casing 2 through the suction port 8 and the fan 11 for circulating air in the bathroom, is heated by the heat exchanger 4 and returns again into the bathtub 1 and the bathroom 14 through the circulating pipes 3, 5 to repeat circulation whereby the temperature of air in the bathroom 14 is increased and, thus, the device may function as a bathroom dryer. |
