Once the output of the water level detection means corresponding to the reference water level is memorized, it is possible to calculate how much the output of the water level detection means will increase if the water level is increased (or decreased) by a certain height relative to the reference water level. (or decrease) is known from the characteristics of the water level detection means itself, so a desired water level can be set based on the reference water level.

ある。Figure 3 shows the normal self-excited hot water supply sequence after the base water level has been memorized.The water level variable switch (18) is operated to determine the set water level, and the hot water temperature setting switch (19) is operated to set the water temperature. After determining the temperature, turn on the automatic hot water supply switch (25), and it will first supply 10% hot water and start the circulation circuit (25).
The interior is filled with hot water and the remaining water is determined. Furthermore, these 10
I! When pouring molten metal, the flow rate is measured using a flow rate sensor (22).
The bath hot water supply solenoid valve (24) is closed, but after the float switch (51) detects that the tank (5) is empty, the three-way valve (8) is switched to proceed to residual water determination. There is. If it is determined that there is no remaining water, add an appropriate amount that exceeds the circulation port of the bathtub (6), for example, 9 [']. After supplying hot water via the loop circuit (7), if it is determined that there is residual water,
Close the bypass solenoid valve (4) and turn off the water level detection means (12).
Hot water is supplied to the bathtub (6) while detecting the water level in the bathtub (6). When the set water level is detected, the bath water supply solenoid valve (2
4) is closed to stop the hot water supply and reheat the water until it reaches the set temperature.

Forced circulation of the bath section and water temperature detection means (
1]) If the rjA lagoon is detected and the temperature has dropped below the set temperature, the bath heater (3) will be used to reheat it to a constant temperature, and when determining residual water or reheating. The water flow is detected by the water aS output means (1 ()), but during circulation, the water level detection means (12)
The water flow may be detected by utilizing the fact that the output of the sensor increases in response to the water flow pressure.
