AUTOMATIC BATH BOILER

Japanese Patent JP3713095

B2

PROBLEM TO BE SOLVED: To prevent a bather from being displeased by water circulation by a pump by a method wherein water supply is prohibited in a normal state during hot keeping operation, and is permitted when the set temperature is lowered.
SOLUTION: When a hot-keeping mode instruction issued from a remote controller, a water supply flag fa is set at 0 to indicate the prohibited state. Therefore, automatic water supply is prohibited in principal during hot-keeping mode (60). When an instruction to lower the set temperature Ts is output (61), the water supply flag fa is set at 1 to indicate the permitted state (62), and enters a standby state until a hot-keeping timer, that controls intervals during hot-keeping mode, runs out (63). When the hot-keeping timer runs out, a water supply routine takes place (65). The water supply routine starts after it is confirmed that the water supply flag fa is set at the permitted state. When the water supply routine comes to end, the water supply flag fa returns to 0 of the prohibited state and the hot-keeping timer is reset.
