論のことである。 In the above configuration, when the operation switch (not shown) of the remote control box 14 is turned on and the circulation pump 5 is activated and the water in the bathtub 13 is circulated, the thermistor 3 detects the water temperature to of the bathtub 13, and the water flow sensor 4
The impeller is rotated by the water flow, and the rotation speed is detected by the detection element 12 to detect the amount of circulating water (/min). After Tmin, the thermistor 3 detects the hot water temperature t 1 and the thermistor 7 detects the hot water temperature t 2 , and if the amount of water in the bathtub is L(), then the amount of heat absorbed by the heat exchanger 6 is ×(t 2 −t 1 ) ×TKcal, and on the other hand, the amount of heat obtained by the water in the bathtub is L (t 1 - t 0 ) Kcal, and assuming that the amount of heat in both is equal, the amount of water in the bathtub L =
×(t 2 −t 1 )×T/t 1 −t 0 (), and the initial amount of water in the bathtub 13 can be detected by the microcomputer. Further, assuming that the amount of heat obtained in one minute by the heat exchanger 6 is QKcal/min, the amount of water in the bathtub 13 can be similarly detected as L=QT/t 1 -t 0 . In reality, there may be heat dissipation loss in the piping, variation in the amount of heat Q due to water temperature, etc., but the amount of water L in the bathtub can be detected by using the above equation instead. Therefore, if we assume that 45℃ is the temperature for boiling bath water,
The boiling time T 1 can be notified by L(45-t 0 )/Q, the bathtub water volume L can be notified, etc., and automation and AV conversion have the effect of convenience. It goes without saying that the water amount sensor 4 may be of a type other than the impeller type.

止できる。 In the above calculation, the boiling time T1 is added to the operation start time and displayed at 16, and the amount of water in the bathtub L is displayed at 17, which also has the effect of being visible from the remote control. Thermistor 3 is 45℃, or thermistor 7 is 45℃+Q/
When this happens, the combustion supply valve 10 can be closed and bath heating can be stopped.
