JPS6456022A - Fine bubble generating bathtub - Google Patents

Abstract

PURPOSE: To return discharged water into a bathtub through the interior of a plug to eliminate the need of newly providing a scupper and a trap inside and outside a bathroom by providing a plug for jetting discharged air from an accumulator into the bathtub. CONSTITUTION: Pressurized bathing water where air in an accumulator 5 is dissolved is sent to a fine bubble jet nozzle 3, and jetting into a bathtub main body 13 to generate a fine bubble current. On the other hand, surplus air which is not dissolved with bathing water in the accumulator 5 is sent to a plug 6 through an air vent valve 7. At this time, though a small quantity of water gets mixed in the surplus air, the discharged water and the surplus air are returned from the plug 6 to the bathtub main body 13. Thus, even in the case where a fine bubble generating device is installed outside a bathroom, it is not necessary to provide a sewage device such as a scupper, a trap and so on for handling the discharged water of the accumulator 5, so that execution of works can be facilitated.
