Abstract

A fluid jet flow massaging apparatus adapted for use within a bathtub unit comprises a first bathtub and a second bathtub which is accommodated within the first bathtub with a space defined therebetween and which has an inner volume sufficient for accommodating a person. The second bathtub is provided with opposed side walls within which a plurality of fluid circulation holes are formed and a fluid jet circulation flow generating device is disposed within at least one hole of at least one wall of the second bathtub. The fluid jet flow caused by the device is circulated through the holes and the space defined between the first and second bathtubs and the fluid jet flow achieves the massaging operation upon the person disposed within the second bathtub as a result of the circulation of the fluid. The fluid flow direction and the fluid flow rate may be regulated by altering the number of fluid flow generating devices.

Dependent claims

A fluid flow massaging apparatus, comprising:

a first bathtub means having four side walls and a bottom wall;
a second bathtub means disposed within said first bathtub means, having four side walls and a bottom wall, and having an inner volume sufficient to accommodate a person to be massaged by a flow of fluid;
first and second hole means defined within two oppositely facing side walls of said four side walls of said second bathtub means such that said first hole means defines a fluid inlet into said inner volume of said second bathtub means, and said second hole means defines a fluid outlet from said inner volume of said second bathtub means;
means defining a space between said first and second bathtub means for fluidically interconnecting said fluid outlet with said fluid inlet such that a fluid circuit is defined within said apparatus as including said fluid inlet, said inner volume of said second bathtub means, said fluid outlet, and said space fluidically interconnecting said fluid outlet with said fluid inlet;
and
means operatively mounted in association with at least one of said first and second hole means for causing said fluid to flow and circulate throughout said apparatus along said fluid circuit.
