PURPOSE:To contrive automatic control in accordance with the bathing habit with time of an user by a method wherein information on set temperatures, which are set and changed by the user from a time of entering a bathtub to a time of coming out of the bathtub, is caught together with the elapse of time to study and store it. CONSTITUTION:The measurement of time is started from a time point when a main controller has detected an entering signal. When the changing operation of a set temperature is effected, a time elapsed to a time point when the changing operation is effected and the changed set temperature are detected. A previous set temperature data Ksi is indicated as an old set temperature data (Ksi-pre), a previous elapsed time data (tci) is indicated as an old elapsed time data (tci-pre), an elapsed time data detected at this time is indicated bye (tci-now), a changed set temperature data (Ksi-now), K, L are integers more than one (1), data (tci), Ksi, which are obtained by formula shown in this page are stored into a memory means as a previous elapsed time data (tci) and a previous set temperature data Ksi newly for the automatic control mode of next time respectively. After detecting the bathing of an user of next time, the hot-water temperature in the bathtub is changed to a temperature set by the set temperature data Ksi when a stored elapse time data (tci) has elapsed. |
