Abstract

PURPOSE:To hit bath hot water in which bubbles are mixed against the whole back face of a bathing person or as a spot by changing the exhaust quantity from many bath hot water exhaust ports provided on the whole inside surface of at least one side wall of a bathtub body by controlling the speed of revolution of a circulating pump of a motor-driven valve. CONSTITUTION:Many pieces of exhaust nozzles 2 which can exhaust bath hot water in which bubbles are mixed are provided extending over the whole inside surface of a bathtub body 1, and the exhaust quantity from each exhaust nozzle 2 can be changed by controlling the speed of revolution of a circulating pump P or a motor-driven valve 9, therefore, for instance, not only bath hot water in which bubbles are mixed can be hit against the whole back face of a bathing person but also the bath hot water in which bubbles are mixed can be hit against a part of the back face as a spot. Also, by varying the exhaust quantity, and varying the bubble quantity in exhausted bath hot water by operating a bubble quantity control valve 8, jet strength can also be varied, and bath hot water in which bubbles are mixed can be hit against a part of choice of the body of a bathing person by jet strength of choice.
