After that, the main valve 34 and the additional heating gas valve 64 are opened, and the ignition signal Sf2 is given to the igniter 66 to flow an electric current to generate heat to ignite the additional heating burner 24.

In U722, Q = N · t / ΔT is calculated from the equation (1). For example, when ΔT = 1 ° C., the water amount Q in the bathtub 20 is Q = N · t.

The rising temperature ΔT may be detected for a certain time t, and the rising temperature ΔT may be stored in the RAM 726 and calculated from the equation (1).

The difference water amount ΔQ is calculated from Q and by the equation (2).

In order to supply b into the bathtub 20, the hot water supply / pouring changeover valve 44

Then, pouring and reheating to a proper amount and temperature is completed.

適制御ができる。When the steps (a) to (h) are used to control the heat retention and the addition of hot water, the pouring and reheating of the water into the bathtub 20 are automatically repeated at regular time intervals. As a result, the optimum control for keeping the water amount Q and the temperature T in the bathtub 20 constant can be performed.

間、Sは追焚インプット能力である。Further, the boiling time t due to the additional heating combustion measured in the step (d) is affected by the thermal efficiency, and factors that lower the thermal efficiency include the material of the bathtub, the additional heating pipe, the outside air temperature, the equipment. There is an error in the specific gas pressure set value. Therefore, the thermal efficiency η is calculated by the following equation: η = Qo × (T2−T1) / S × to (3) by the CPU 722 at each additional heating time, and the RAM 72 is calculated.
It is stored in 6, and the value is updated every time it is fired. Here, Qo is the set amount of water (= the amount of pouring water), T1 is the uniform temperature of the water supplied to the bath 20 during the pouring operation, T2 is the uniform boiling temperature (= set boiling temperature), and to is the boiling time. , S is an additional input capability.

き、この場合には追焚モードに移行しない。In detecting and controlling the amount of water in the bathtub 20, as shown in FIG. 3, when the water level hw is lower than the circulation port 54 in the bathtub 20, in the step (a), the water 4c is added. Since it does not circulate in the circulation conduit 60, it can be discriminated from the water flow detection signal Dw2 of the water flow sensor 62, and in this case, it does not shift to the additional heating mode.

After the water level is raised above the circulation port 54 by supplying the water amount, the steps (a) to (h) are performed, but the water amount corresponding to 1/2 of the set appropriate water level hwo of the bath 20 is set.
