Abstract:
The objective of the present invention is to provide a bathtub device that suppresses hot flashes of a bather and enables a relatively long time of bathing. The bathtub device according to the present invention comprises: a spout 8 provided above a bathtub body; a circulation flow path 4 that provides communication between a water intake portion and the spout; a circulation pump 6 provided in the circulation flow path; a temperature adjustment unit 7 that adjusts the temperature of hot water supplied to the spout; a detection unit 22 that detects the temperature of hot water in the bathtub body; and a control unit 16 that controls the temperature of the hot water supplied to the spout. The control unit executes: a discharged water temperature adjustment mode in which, when the temperature of the hot water in the bathtub body is higher than an upper limit temperature of a predetermined temperature range, the temperature of the hot water discharged from the spout into the bathtub body is lowered to fall within the predetermined temperature range; or a discharged water temperature adjustment mode in which, when the temperature of the hot water in the bathtub body is lower than a lower limit temperature of the predetermined temperature range, the temperature of the hot water discharged from the spout into the bathtub body is raised by the temperature adjustment unit to fall within the predetermined temperature range.
