When the filter 13 determines that the water can be used as the middle water in the filter 13, the water is supplied to the water storage tank 77 through the water distribution pipe 34.

If it is determined that the water cannot be used, it is connected to the water distribution pipe 27 and drained to the sewage. Further, when the power supply of the water distribution switching means 70 is stopped, the water distribution switching means 70 is connected from the water distribution pipe 31 to the water distribution pipe 27.

When the control circuit 75 detects that the wastewater used in the LD 21 has been generated, the control circuit 73 of the water distribution switching means 71 switches the water distribution switching means 71 from the sewage line 27 to the water distribution pipe 31 as in the case of SK20. At the same time, the pump 29 starts operating, and the waste water reaches the filter 13 through the water pipe 31.

When the filter 13 determines that the water can be used as the middle water in the filter 13, the water is supplied to the water storage tank 77 through the water pipe 34. If it is determined that it cannot be used, it is connected to the water distribution pipe 27 and drained to the sewer.

When the power supply of the water distribution switching means 71 is stopped, the water distribution switching means 71 is connected from the water distribution pipe 31 to the sewage line 27.

In the above-described embodiment, when the drainage operation from the SK 20 and the LD 21 is detected by the control circuits 74 and 75, the control circuit 76 of the water storage tank 77 starts the operation of the pump 29,
It is configured to be pumped to a water storage tank.

In this embodiment, a pump 29 and a pump 78 are provided. When the remaining hot water in the bath 22 is used as a supply source of the middle water, the pump 54 of the water heater 24 is used, and the SK 20 and L
When the drainage from D21 is used as a supply source, the reused water is transferred to the water storage tank 77 using the pump 29. In addition, when the water is transferred from the water storage tank 77 to the equipment using the medium water, the water in the tank is pumped by the pump 78. However, when the reused water is transferred to the water storage tank 77, the pump 29 is used. It is also possible to configure so that In the case of this configuration, the remaining hot water in the bath can be sent to the water storage tank even when the hot water supply device 24 is of a normal type without the pump 54.

FIG. 3 shows a positional relationship among the bath 22, the water storage tank 11, the water distribution switching means 23, and the filter 13.
