PURPOSE:To permit to take out the waste hot-water of bath efficiently and use it conveniently for water for washing or the like by a method wherein a branched pipe for supplying hot-water is connected to a three-way valve interposed in a pipeline connecting bathtub to the heat exchanger of a heater. CONSTITUTION:In the bath device 1, the branched pipe 9 is connected to the three-way valve 7, interposed in the pipeline 6 connecting the bathtub 2 to the heat exchanger 4 of the heater 3. The heater 3 is provided with a burner 11 for burning gas or the like and said heat exchanger 4 heated by the combustion heat of the burner. The pipeline 6 comprises the pipeline 14, connecting said inlet port 12 to the bathtub 2 and arranged at the upstream side of the heat exchanger 4, and the pipeline 15, connecting said outlet port 13 to the bathtub 2 and arranged at the downstream side of the heat exchanger 4. A pump 17, sending bath water from the bathtub 2 to the inlet port 12, is interposed in the upstream side pipeline 14 while said three-way valve 7, whose two ports 19, 20 are connected to said pipe line 15, is interposed in the downstream side pipeline 15. One port 10 of the three-way valve 7 is connected to the branched pipe 9 provided with a cock 23 and communicated with a washing machine installing section 22, in which a washing machine 21, for example, is installed. |
