Description

FIELD OF THE INVENTION

The present invention relates, in general, to whirlpool jet units used to re-circulate a fluid contained within hydrotherapeutic receptacles such as whirlpools, spas, hot tubs or bathtubs and, more particularly, the invention relates to a whirlpool jet unit for re-circulating a fluid contained within a hydrotherapeutic receptacle without the need for excessive piping to either of a motor or a water pump system used to re-circulate the fluid.

BACKGROUND OF THE INVENTION

Whirlpool jet units used in hydrotherapeutic receptacles to relax and soothe muscles and joints in people have been in existence for many years. The jet stream is directed into the receptacle through fixed nozzles positioned in the side walls of the receptacle that receive water under pressure through a piping system from a water pump.

One problem with these units is that the jet steams must generally travel a long distance to reach an occupant on the other side of the receptacle, thus creating the need for a large pump and pipes to create the desired effect. These large components, obviously, increase the cost and complexity of the units.

Another problem that arises is cleaning and servicing the various jet components when positioned in the side walls of the receptacle. Many of the jet nozzles are complex and not easily accessible for cleaning out the various detrimental deposits from the water, and possibly other therapeutic solvents mixed with the water, that can clog the jet nozzles.

Thus, a need exists for a less complex whirlpool jet unit that can be easily installed in such hydrotherapeutic receptacles and, also, once installed, can be easily disassembled for cleaning and maintenance.

SUMMARY OF THE INVENTION

The present invention provides an apparatus for re-circulating a fluid contained within a hydrotherapeutic receptacle, such as a whirlpool, a spa, a hot tub or a bathtub, without the need for piping to either of a motor or a water pump system. The apparatus includes at least one jet housing having a portion thereof engageable with such hydrotherapeutic receptacle. A nozzle means is located at one end of the jet housing to provide an entrance for a predetermined amount of fluid to be suctioned into the jet housing and an exit for a predetermined amount of suctioned fluid to be expelled from the jet housing. A control means is located adjacent the nozzle means to control fluid flow of such predetermined amount of fluid suctioned into the jet housing and fluid flow of such predetermined amount of fluid expelled from the jet housing. An expulsion means is located adjacent the control means to expel such predetermined amount of fluid from the jet housing back into such hydrotherapeutic receptacle. A power source is connected to the expulsion means to enable the expulsion means to expel such predetermined amount of fluid from the jet housing at a predetermined pressure into such hydrotherapeutic receptacle at a predetermined rate.

OBJECTS OF THE INVENTION

It is, therefore, one of the primary objects of the present invention to provide a hydrotherapeutic whirlpool jet apparatus that eliminates the need for excessive piping to and from a motor or water pump system.

Another object of the present invention is to provide a hydrotherapeutic whirlpool jet apparatus that can operate using minimal water levels.

Still another object of the present invention is to provide a hydrotherapeutic whirlpool jet apparatus that is much easier to install than prior hydrotherapeutic whirlpool jet units.

Yet another object of the present invention is to provide a hydrotherapeutic whirlpool jet apparatus that can be easily disassembled for cleaning and servicing.

An even further object of the present invention is to provide a hydrotherapeutic whirlpool jet apparatus that is cost effective over whirlpool jet units being used now.

In addition to the above described objects and advantages of the present invention, various other objects and advantages of the hydrotherapeutic whirlpool jet apparatus will become more readily apparent to those persons skilled in such art from the more detailed description, particularly, when such description is taken in conjunction with the attached drawing figures and with the appended claims.
