<p>PURPOSE:To provide a bath which can constantly satisfy a set temperature in a bath tub irrespective of a change in the water level by a method in which, only when the set temperature in the bath tub is changed from a temperature of hot water in the bath tub, an electromotive valve is opened to exhaust waste hot water, and hot water or cold water is supplied into the bath tub up to a set water level. CONSTITUTION:Temperature of hot water in a bath tub 6 is detected by a temperature detector 15. If a difference exist between a set temperature of the hot water in the bath tub and a temperature detected by the temperature detector 15, an electromotive valve 20 is opened to drain out a prescribed amount of hot water in the bath tub 6, and then the valve 20 is closed. After that, a hot water pouring valve 17 is opened to pour hot water into the bath tub 6, which has a temperature discriminated by a control circuit based on the set temperature of the hot water in the bath tub 6, whereby an automatic supplement of hot water is made until a water level in the bath tub 6 reaches a set value. Then a circulation pump 11 is operated to stir the hot water in the bath tub 6 for a prescribed time period, and only when the set temperature of the hot water in the bath tub 6 continues to be the same as that detected by the temperature detector 15 for a prescribed time period, the operation of the circulation pump 11 is stopped.</p> |
