<p>PURPOSE:To provide an automatic bath apparatus capable of reaching a bathtub set temperature after a fixed time passes by detecting a non-human body bathing state by a water level detection means. CONSTITUTION:This apparatus is provided with a heat exchanger 4 for supplying hot water, a heat exchanger 15 for followup boiling and a water level detection means 14 and a filling of hot water, as heated with the heat exchanger for supplying water, is performed through a circulation followup boiling circuit 11. Automatic filling of hot water is stopped by the water level detection means when the water level of the hot water reaches a set value and after the stoppage thereof, the hot water in the bathtub is subjected to a followup boiling or a lowering of the temperature as required. A first judging step is arranged to judge whether a change in a water level is above a fixed value (h) during a certain period of time (y) and a second judging step to judge the change in the water level during a certain period of time (z) after the first judging step to detect the non-human body bathing state by monitoring the water level in the bathtub after the automatic filling of the hot water. A control is performed that the hot water is kept tepid by lowering the temperature thereof down to a bathtub set value or heated by raising it up to the set value as required after the passage of a fixed time T0.</p> |
