Description

AQUATIC VESSEL FILTERREFERENCE TO RELATED APPLICATIONS

[0001] This application claims the benefit of and priority to U.S. provisional application 63 / 664,768 filed on June 27, 2024, the entire contents of which is incorporated herein by reference in its entirety.TECHNICAL FIELD

[0002] This disclosure relates generally to aquatic vessels and, more particularly, to filters for aquatic vessels.BACKGROUND

[0003] Aquatic vessels, including spas, pools, and the like, typically include a main container that holds water to be used for recreational, medical, or other purposes, a filter bucket that holds water to be filtered, and a pump that circulates water between the filter chamber and the main chamber. Maintaining quality of water in an aquatic vessel is important to users of the aquatic vessel. Water maintenance typically includes removal and replacement of a filter in the filter bucket.

[0004] Presently available aquatic vessel filters generally include a cylindrical housing and a pleated paper filter carried by the housing or a sintered polymeric filter carried by the housing. But pleated paper filters provide only a single layer of filter media, albeit with a relatively large surface area by way of pleats, but frequently such pleated media fails when closely spaced pleats collapse. Also, sintered polymeric filters tend to be single-use filters as they clog irreversibly, and they are relatively costly. Both pleated paper filters and sintered polymeric filters also tend to be prone to chemical attack, particularly in hot tub or spa environments. Additionally, a typical standpipe for an aquatic vessel may impose an unnecessarily high pressure drop across a filter coupled to the standpipe, thereby leading to unnecessarily low fluid flow to the filter. Also, the typical standpipe is not well adapted for use with improved filter designs.SUMMARY OF THE DISCLOSURE

[0005] An illustrative embodiment of an aquatic vessel filter includes a core filter element, a plurality of peripheral filter elements circumscribing the core filter element, and a cage circumscribing the plurality of peripheral filter elements.

The cover 20 may be composed of ABS and polypropylene, or ASA, polyethylene, or engineered plastics, or of metal, for instance, stainless steel, or aluminum, or of any other materials suitable for a filter. The gasket 22 (FIG. 14) may be trapped between the base wall 136 of the cover 20 and the caps 70 of the peripheral filter elements 14. The gasket 22 may be a flat annular ring, a O-ring , or any other gasket of any suitable geometry. The gasket 22 may be composed of an elastomeric material, such as, TPE - EDPM, Viton, PVC, silicone, Buna-N, or any other material that is suitably compliant to take up slack in the assembly due to axial tolerance stackups of the individual components. Adhesive may be applied between the various components, and the entire assembly may be clamped together in a fixture (not shown) to complete the filter 10.
