ABSTRACT:

TECHNICAL FIELD
This invention relates, in general, to hydrotherapy tubs and, in particular, to a fluid flow system usable for creating fluid flow in hydrotherapy tubs and a method for controlling fluid flow.
BACKGROUND ART
Hydrotherapy tubs, spa assemblies and like systems have enjoyed increased popularity in recent years. In the majority of such systems, a contained space is at least partially filled with a fluid, such as water, which continuously is circulated throughout the contained space. A fluid directing structure is provided to include one or more jet streams of water directed into the interior of the contained space to create a certain amount of water turbulence.
In a conventional spa assembly or system, the tub or pool like structure is generally formed of rigid material and permanently mounted or fixed either in ground or above ground at a specific location. Fixed plumbing typically in the form of rigid material conduits, pumps, heating structures, etc. are then mounted at this given location in communication with the interior of the rigid material tub or pool to create the desired treatment of water being circulated. Hydrotherapy tubs generally have a number of fluid flow outlets or nozzles. Each flow nozzle usually jets water or a water-air froth into the tub. Enhanced hydrotherapy typically results from strategic positioning of these fluid flow nozzles at various locations in the tub. The one or more flow nozzles located throughout the tub generally direct streams of water to specific locations of the user which aids in hydrotherapy of that location.
Some fluid flow nozzles have the user controlled ability to direct a single jet stream of water into different positions, by rotating or pivoting the fluid flow nozzle. However, providing hydrotherapy to multiple areas at the same time has been limited by the number and placement of the fluid flow nozzles. In general these nozzles have been placed in specific locations by the manufacturer and cannot be relocated without significant work and expense. Therefore, if a user wishes to provide hydrotherapy to two or more locations at the same time, there may be difficultly due to nozzle placement.
Thus, a need exists for enhanced strategic directioning of the fluid flow paths thereby enabling a user to direct fluid, from a single outlet, to more than one location at the same time.
SUMMARY OF THE INVENTION
The present invention provides, in a first aspect, a fluid flow system for a spa. The fluid flow system includes an ejector which discharges fluid in a first direction toward an interior of the spa through an outlet of the ejector and a diverter which is movable to a position within said first direction between the outlet and the interior of the spa. The diverter is adapted to deflect at least a portion of the fluid to a second direction different from the first direction.
The present invention provides, in a second aspect, a fluid flow system for a spa. The fluid flow system includes an ejector which discharges fluid toward an interior portion of the spa through an outlet of the ejector and a diverter ring which surrounds at least a portion of the ejector wherein a circumferential portion of the diverter ring is adapted to alter the direction of fluid discharge.
The present invention provides, in a third aspect, a diverter ring for use with a fluid flow ejector wherein the diverter ring includes a plurality of diverters for altering a direction of fluid discharge from the fluid flow ejector and wherein the diverter ring is connectable to the fluid flow ejector.
The present invention provides, in a fourth aspect, a method of controlling fluid flow of a spa. The method includes providing a diverter between a fluid flow ejector and an interior portion of the spa, discharging fluid from the fluid flow ejector in a first direction, and deflecting at least a portion of the fluid to a second direction different from the first direction.
