PURPOSE:To enable bathtub water to be uniformly cooled, by a method wherein air is heated by the waste heat of a bath boiler, and is pressure-fed to the bathtub water to be mixed with each other, the temperature of the bathtub water is made uniform, the combustion of the bath boiler is stopped, and air heated is pressure-fed to and is mixed with. CONSTITUTION:Bathtub water is heated by combustion gas through a bath boiler 1, and after that, air pressure-fed through an air heater 4 is heated and is discharged from a smoke tube 8. Air pressure-fed by an air compressor 3 is heated by the air heater 4, and is fed to an air sprayer 5 set at the lower section of a bathtub 6, and is mixed with the bathtub water, and is moved upward to heat the bathtub water to stir it to set it at a uniform temperature. Besides, when overboiled hot water cannot be diluted with water, then, if the fire of a combustion device 7 is extinguished and air is pressure-fed without being heated, the bathtub water is cooled to come to a uniform temperature. |
