<p>PURPOSE:To remove restrictions in regard to installing a bath boiler and overcome inconveniences of usage, by providing a steam generator connected to the bathtub via two pipes of steam pipe and water return pipe, a check valve in the water return pipe which allows flow only from the bathtub to the steam generator, and a mechanism to control fuel supply to the heating source. CONSTITUTION:The float actuating gas valve 15 is directly connected to the float 13 in the float chamber 12 attached to the steam generator 11, and is closed when the water level of the boiler water 18 drops to as low as a specified limit. The steam pipe 20 has at its end a steam injection nozzle 24, and the return water pipe 21 has a check valve 17 so that the only one way flow from the bathtub 22 to the steam generator 11 is made possible. In this constitution, by automatically repeating the steam generation and return flow of the bathtub water, the bathtub water 23 is heated.</p> |
