PURPOSE:To enable a specified amount of hot water of desired depth to be fed into a bath tub without having any relation with a bath adaptor fixing position by a method wherein a cross sectional area of the bath tub is multiplied by a distance up to a set water level to calculate a required total amount of water. CONSTITUTION:An automatic bath device is comprised of a hot water feeding circuit 4 for use in feeding hot water into a bath tub 2, an additional boiling circuit 3 for performing an additional boiling of hot water in the bath tub, an indirect water level sensing means such as a pressure sensor 9 for use in sensing a water level in the bath tub, a flow rate sensing means 15 for sensing an amount of water of hot water supplied into the bath tub and a controlling part. A specified amount of hot water is repetitively fed into the bath tub until an increased amount of water level more than the specified value is attained, a total amount of increased water level at the beginning of dropping and at the end of dropping is detected and a cross sectional area of the bath tub is calculated in response to a total amount of water fed into the bath tub and the increased amount of water level detected. Then, an amount of hot water corresponding to a multiplication between a distance up to a set water level with a bath tub bottom surface of a reference plane stored in advance and the cross sectional area of the bath tub is supplied into the bath tub and then the hot water is supplied to the set water level. |
