Problems solved by technology

The single inlet and outlet arrangement limits the flexibility available to a pool designer when designing the piping system for a pool or spa.
This limited flexibility may be issue when the pool filter is located in a confined or limited space, or when placing the pool filter in an already plumbed pool piping system.
Yet another issue with pool filters is the drain outlet is often smaller than both the fluid inlet and the filtered fluid outlet.
This size difference requires different sized fittings for the drain outlet and the fluid inlet and outlet, which increases manufacturing costs and requires different sized tools for assembling the pool filter.
Still yet another issue is pool filters typically are set directly on pads or other support surfaces without anchoring the pool filter to the support surface.
In areas subject to earthquakes or hurricanes, the pool filter may undesirably tip over during such an event, resulting in potential disconnection of the pool filter from the pool piping system.
Such disconnection may permit chemicals or other potentially hazardous materials used in the pool circulation system to enter the surrounding environment.

Embodiment Construction

[0021]Described herein are various embodiments of a pool filter for use in a fluid conveyance system, such as a pool piping system. The pool filter may take the form of a housing defining a fluid chamber configured to receive one or more filters, such as filter cartridges. Multiple openings may be defined by the housing for receiving fluid into the fluid chamber, delivering filtered fluid from the fluid chamber, and draining fluid from the fluid chamber. The openings may be approximately the same size. At least some of the openings may be located on similar radial sectors or sides of the housing and / or at similar elevations on the housing. One type of fitting for joining pipes, tubes, or hoses to the pool filter may be used with each opening. At least one opening may be positioned at a lower end portion of the housing. Such a lower positioned opening may function as a drain, thus allowing gravity to assist in draining fluid from the fluid chamber for cleaning, maintaining, or replac...

Abstract

A pool filter for use in pool piping or other fluid conveyance system. The pool filter may include a housing defining a fluid chamber for receiving one or more filters. Multiple openings may be defined in the housing for receiving and removing fluid from the fluid chamber. The openings may be approximately the same size and may be located on the housing at similar elevations and / or radial sectors. One or more footings may be joined to the housing. Each footing may include a base portion for receiving anchor members to anchor the housing to a support surface. The footings may be designed to transfer to the support surface predetermined lateral or other forces imposed upon the pool filter by events such as earthquakes and hurricanes. The footings may be separate components joined to the housing by tabs and / or mechanical fasteners.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a divisional of U.S. patent application Ser. No. 11 / 967,664, entitled “Pool Filter” and filed Dec. 31, 2007, now U.S. Pat. No. ______, which claims the benefit under 35 U.S.C. §119(e) of U.S. Provisional Application No. 60 / 896,797, entitled “Pool Filter” and filed on Mar. 23, 2007, both of which are hereby incorporated by reference herein in their entirety.FIELD OF INVENTION[0002]The present invention generally relates to filters, and more specifically to pool filters.BACKGROUND[0003]Pool filters are used in pool or spa fluid circulation systems to filter water used in a pool or spa. Pool filters often include a single inlet for receiving water, a single outlet for delivering filtered water from the pool filter, and a drain outlet for draining water from the pool filter. The single inlet and outlet arrangement limits the flexibility available to a pool designer when designing the piping system for a pool or spa. This li...
