  • Patent number: 5896596
    Abstract: An apparatus for generating a high power water stream performing an effective massage without producing undesired vibration and noise including an outer tub 1, an inner tub 2 arranged within the outer tub, passages 3 formed in a bottom wall of the outer tub, passages 2c formed in a side wall of the inner tub, a tubular members 4 provided at the passages 2c and having inner diameters which are gradually increased toward an inner space S3, a pump 5 arranged between a space S2 between side walls of outer and inner tubs and having jet nozzles 8 which are positioned at inlets of the jet nozzles, and a motor 7 coupled with the pump 5 by means of a drive shaft assembly 6. When the motor 7 is energized to drive the pump 5, water streams are projected at a very high speed from the jet nozzles into the tubular members 4. Then, the water in the space S2 is sucked into the inlets of the tubular members, and the water streams are projected from the outlets of the tubular members 4 at a very high speed.

  • Patent number: 4903352
    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.
