| description | PROBLEM TO BE SOLVED: To provide a cellular bathtub apparatus which can jet two kinds of large and small bubbles and has simple structure at low costs. SOLUTION: This cellular bathtub apparatus is provided with: a bubble jetting nozzle for jetting air into the bathtub; and an air pump which is connected to the nozzle via piping and can vary the pressure of the air to at least two stages. The nozzle has a plurality of first bubble jetting ports in the state of open holes and second bubble jetting ports each in the state of a mesh where the opening area of a single square is smaller than that of the first bubble jetting port in the state of the open holes. Thus, a difference is made in jetting pressure due to the relation of the surface tensions of water and air. Then, when air pressure fed from the air pump is low, small bubbles are jetted only from the plurality of the first bubble jetting ports in the state of open holes at the bubble jetting nozzle. When the air pressure fed from the air pump is raised, large bubbles are jetted from the second bubble jetting ports in the state of the mesh state. COPYRIGHT: (C)2004,JPO |
