Abstract

A sanitary, cleanable, whirlpool jet apparatus having means for circulating water within a whirlpool without routing the whirlpool water through circulation piping.

Claims

1. A whirlpool jet apparatus comprising:

a jet casing adapted to be mounted in a tub aperture in a water tight manner, said casing providing an open end facing into a tub interior and a closed end;

a jet assembly being housed in said casing, said assembly being insertable and removable through said open end and said assembly being operably housed substantially within said casing by hand manipulatable means for retaining;

said jet assembly when housed and retained being engaged with means on said casing for driving said assembly to produce jetted water to be ejected through said open end.

2. The whirlpool jet apparatus according to claim 1, wherein said jet assembly comprises an external housing and internal means for receiving and pumping water.

3. The whirlpool jet apparatus according to claim 2, wherein said internal receiving and pumping means comprises:

a nozzle located within the external housing of the jet assembly for directing an axial discharge of water into the tub interior; and

an impeller located behind the nozzle within the external housing of the jet assembly for generating an axial flow of water through the nozzle into the tub interior.

4. The whirlpool jet apparatus to claim 3, wherein said external housing of said jet assembly comprises an intake stator having a cavity for receiving said impeller and said nozzle, said intake stator removably coupled to a jet escutcheon having holes about an outer peripheral surface thereof for drawing water from the tub interior into the jet assembly.

5. The whirlpool jet apparatus according to claim 4, wherein said intake stator is removably coupled to said jet escutcheon by hand manipulatable means for securing.

6. The whirlpool jet apparatus according to claim 4, further comprising a filter located behind the holes of the jet escutcheon for preventing solid material from entering the jet assembly.

7. The whirlpool jet apparatus according to claim 1, wherein the said driving means engages the jet assembly through a hole in the closed end of the jet casing and sealingly and rotatably communicates with the hole.

8. The whirlpool jet apparatus according to claim 7, wherein said driving means is mechanical.

9. The whirlpool jet apparatus according to claim 8, wherein said mechanical driving means comprises a motor connected to the jet assembly by a flexible drive shaft.

10. The whirlpool jet apparatus according to claim 9, wherein a motor is connected to a plurality of jet assemblies by a corresponding plurality of flexible drive shafts.

11. The whirlpool jet apparatus according to claim 1, wherein said jet assembly is comprised of a plurality of components, said plurality of components being insertable and removable from said casing as a one-piece unit.
