When the buzzer 23 sounds, the bathtub hot-water tap 9 is immediately closed, and then, when the hot water release switch 24 is turned on, the buzzer 23 stops sounding, the water flow control valve 12 is opened, and the general hot water supply control is started. On the other hand, when the hot water in the bathtub 8 is insufficient, the bathtub hot water tap 9 is closed after waiting for the desired hot water quantity. In any case, if only the buzzer 23 is stopped sounding by the hot water release switch 24 without closing the bathtub hot water tap 9, the water continues to flow in the water supply channel 5 due to the continuation of the hot water supply. The flow sensor 10 detects the flow of water. Thus, immediately after the water filling switch 24 is turned on, the water flow rate sensor 10
Detects that water is flowing, determines that the user has forgotten to close the bathtub hot water tap 9, does not accept the stop of the buzzer 23, continues to sound the buzzer 23, and continues to sound the bathtub hot water tap 9.
It informs you of forgetting to close. Therefore, buzzer 2
In order to stop the ringing of 3, it is necessary to close the hot-water tap 9 for the bathtub, and thereafter, the general hot-water supply control can be executed only by turning on the hot water release switch 24.
