る。 When hot water is to be supplied into the bathtub 5, as shown in FIG. 2, when it is detected in step ( S1 ) that the bath firing switch 30 is turned on, the control device 27 operates the circulation pump 6. (Step (S 2 )) After this, if the water flow sensor 7 is turned on for a predetermined period of time in step (S 3 ), the process proceeds to step (S 4 ), and if it is not turned on, the process proceeds to step (S 5 ). The hot water supply valve 13 is opened and hot water is supplied into the bathtub 5 through the hot water supply path 12. If the water supply turns on the water flow sensor 7 in step (S 3 ), the circulation pump 6 is stopped in step (S 4 ), and then in step (S 6 ) if the pressure sensor 14 is not turned on. In step (S 7 ), hot water supply valve 13 is opened, and hot water is supplied into bathtub 5 until pressure sensor 14 turns on in step (S 8 ).

追焚きを行なう。 Moreover, when hot water is supplied to the prescribed water level in the bathtub 5 as described above,
At step (S 9 ), the circulation pump 6 is operated again.
In step (S 10 ), the temperature of the bath water 28 is detected using the temperature sensor 16, and if the temperature is higher than the set temperature suitable for bathing (for example, 42°C), the process proceeds to step (S 11 ).
The circulation pump 6 is stopped at . On the other hand, if the temperature is below the set temperature in step (S 10 ), the process proceeds to step (S 12 ), where the bath burner 19 is burned to perform so-called reheating.

（S12）を実行する。 Furthermore, in the above step (S 3 ), when a relatively inexpensive switch is used as the water flow sensor 7, the water flow sensor 7 is turned off when there is no water flowing through the circulation channel 11, and on the other hand, if there is no water flowing through the circulation channel 11, the water flow sensor 7 is turned off. If there is residual hot water and air is mixed in the circulation flow path 11, the water flow sensor 7 will turn on and off irregularly, so this is detected. This is to detect whether the water is full or not, and to accurately detect the water level using the pressure sensor 14. Therefore, a sensor that detects the flow rate in the circulation flow path 11 may be used as the water flow sensor 7. Further, when only reheating the bath water 28 is to be performed, the above steps (S 9 ) to (S 12 ) are executed.

ものである。(g) Effects of the invention As explained above, the present invention is a system that uses a pressure sensor installed in the circulation flow path of the bathtub to detect the water level in the bathtub and fills the bathtub with hot water. When there is very little water, hot water is supplied to the bathtub while the circulation pump is running to fill the circulation path of the bath with water, and then hot water is supplied to the bathtub according to the signal from the pressure sensor while the circulation pump is stopped. As a result, water level detection using the pressure sensor can be performed with high precision regardless of the height of the bathtub.Moreover, the pressure sensor can detect the influence of the circulation pump's discharge pressure during water level detection without adding any additional parts. This allows for accurate filling of hot water without complicating the structure.
