The forced circulation capacity of the circulation pump (P) is set by the weak drive circuit (K ₁ ). Therefore, all of the overflow water from the bathtub (1) does not flow into the auxiliary tank (30) from the inflow port and overflow.

Thereafter, when the bathroom floor is heated prior to bathing, the changeover switch is set to a state in which the strong drive circuit (K ₂ ) is conducted. As a result, the circulation pump (P) enters a strong operation state in which the forced circulation capacity is set large, and the amount of hot water supplied into the bathtub (1) exceeds the amount of hot water flowing into the auxiliary bath (30). The surplus overflows from the auxiliary tank (30) outside the bathtub (1). Thereby, the bathtub floor surface is heated.

On the other hand, since the hot water in the bathtub (1) is drawn out and the water level in the auxiliary tank (13) drops, the hot water control device is activated to fill the hot water from the hot water supply (A). The bathtub (1) returns to a full state. Therefore, when the state in which the strong drive circuit (K ₂ ) side is turned on by the changeover switch is maintained for a certain period of time, the state in which the hot water overflows from the auxiliary tank (30) is continued, and the filling operation is continued. You. Thereafter, when the changeover switch is returned to the normal state connected to the weak drive circuit (K ₁ ), the overflow of the hot water from the auxiliary tank (30) is stopped, and immediately thereafter, the hot water filling operation is stopped, and Due to the forced circulation capacity of the circulation pump (P) set by the drive circuit (K ₁ ), the inside of the bathtub is maintained in a full state.

As described above, the warm water can overflow from the auxiliary tank (30) outside the bathtub (1) as required by operating the changeover switch provided on the remote control panel (2b). The surface can be heated.

[0014]

According to the present invention having the above configuration, the following specific effects are obtained. Since the bathroom floor is heated by the hot water overflowing from the bathtub (1), discomfort during bathing is eliminated. Moreover,
Since no special piping is required for the heating device, the structure of the bath device including the bathroom floor heating device can be simplified. Since the bathroom floor surface can be arbitrarily heated by operating the open operation unit in the operation unit (43) provided outside the bathroom, the usability is good. In addition, since the inside of the bathtub (1) is always kept full, there is no draft on the inner surface of the bathtub, and there is no fear that dirt adheres to the inner surface of the bathtub.

Also, since there is always plenty of hot water, you can comfortably take a bath.
