[0019]
The operation of this automatic bath apparatus will be described with reference to the flowcharts of FIGS. A and B in FIGS. 3 and 4 are connectors between the flowcharts. Step S1 represents the start of hot water filling control. In this step S1, the hot water supply valve 18 is opened, the switching valve 23 is switched, hot water HW is poured from the hot water supply heater 6 into the bathtub 2, and the bathtub 2 is set to the set amount of water. To do. At this time, the circulation pump 36 is operated to circulate the bathtub water BW of the bathtub 2 and is heated by the reheating heater 8 to boil the bathtub water BW to a set temperature. In step S2, it is determined whether the hot water has been poured into the bathtub 2 up to the set amount of water, or whether boiling has been completed up to the set temperature, and hot water filling control is continued until pouring or boiling is completed.
[0020]
If hot water filling control is completed, it will transfer to step S3 and will transfer to heat retention control operation | movement. This heat retention control is performed during a preset heat retention time. At this time, in step S4, the heat retention time timer 48 is cleared, that is, reset, and time counting is started, for example, a heat retention time of 4 hours is counted. At this time, in step S5, the heat retention interval timer 50 in which the time of the chasing interval is set is cleared, that is, reset to start timing.
[0021]
During this heat retention time, in step S6, it is determined whether or not the operation of the water pouring switch 72 or the hot water pouring switch 74 has been performed, that is, whether or not the operation has been shifted to pouring water (pour water) or pouring water (pour water). . When the process proceeds to pouring or pouring, in step S7, the pouring valve 26 or the pouring valve 18 is opened, and a predetermined amount of pouring or pouring is performed on the bathtub 2. At this time, in step S8, it is determined by the detection output of the water amount sensor 22 whether or not a predetermined amount of water or water has been poured by starting water injection or water pouring. Further, it is determined whether or not an instruction to stop pouring or pouring is made by operating the pouring switch 72 or the pouring switch 74. And in step S9, the water injection valve 26 or the hot water injection valve 18 is closed, and the water injection or the hot water supply to the bathtub 2 is stopped.

In step S16, the presence or absence of flowing water by pump circulation is confirmed by the output of the flowing water switch 38, and then the temperature T of the circulating bath water BW is detected by the temperature sensor 34. In step S17, it is determined whether or not the detected temperature T is lower than the set temperature Ts. If the detected temperature T is lower than the set temperature Ts, the process proceeds to step S18 to operate the additional heating device 8 to heat the bath water BW. If it is equal to or higher than the set temperature Ts, the process proceeds to step S21 to cancel the chasing operation.
[0026]
In step S19, it is determined whether or not the detected temperature T of the bath water BW is equal to or higher than the set temperature Ts. When the temperature is raised to the set temperature Ts or higher, the process proceeds to step S20 and the operation of the remedy heating device 8 is stopped. At the same time, the process proceeds to step S21, where the circulation pump 36 is stopped and the chasing operation is finished.
