Benefits of technology

In accordance with the present invention, the desirable long and thin-walled solid porous hollow cylinder is reconfigured as two or more short cylindrical portions which are operated in a parallel fashion as a flat arr...

Problems solved by technology

However, this presents a problem, especially when the element is employed in a domestic water filtration unit such as might be maintained at a kitchen or bathroom sink.
In order to achieve the desired flow volume, a long and ungainly filter element would be required.
A second problem is that the changing of filter e...

Embodiment Construction

The invention comprises a base member and a filter cartridge which is insertable into the base member. The cartridge is illustrated by FIGS. 1-7 and the base by FIGS. 8-10. Reference may also be had to FIG. 12 which illustrates the cartridge 10 mounted in the base 12.

Cartridge

The cartridge 10 comprises a main housing of substantially rectangular cross-section comprising a front wall 14, a rear wall 16, left 18 and right 20 side walls, and a top wall 22 (FIG. 12). A stiffening web 24 extends downwardly from top wall 22 between front wall 14 and rear wall 16. The stiffening web performs the important function of preventing deformation of the housing when under full line water pressure. This allows for a relatively flat housing, as opposed to the cylindrical housings of the prior art. A cartridge base 26 closes the bottom of the housing. It is in the form of a base plate 28 from which extend a hollow water inlet stud 30 and a similar water outlet stud 32. The studs 30, 32 have axial bo...

Abstract

A water treatment unit includes a base and a disposable, plug-in cartridge. The cartridge contains a pair of hollow cylindrical, porous, solid water treatment elements designed to treat water flowing radially through their walls. The cylindrical elements are mounted so as to act in parallel, thereby achieving the advantages of a long, thin-walled element in a compact configuration.

Description

TECHNICAL FIELDThis invention relates to apparatus for treating water. More particularly, it relates to water filtration apparatus in the form of a disposable cartridge and a base therefor.BACKGROUND ARTThe use of disposable water treatment elements such as filters is well-known. One type of such filter is the form of a solid porous cylinder having a hollow center. When such an element is employed, the water or other liquid to be treated or filtered flows radially through the wall of the cylinder between its exterior and its hollow core. Examples of such an element are the well-known ceramic filter and the extruded solid activated carbon filters made by the method and apparatus disclosed in Koslow U.S. Pat. Nos. 5,189,092; 5,249,948; and 5,331,037. See also the co-pending U.S. patent application Ser. No. 08 / 607,294 filed Feb. 26, 1996 of Koslow, et al (pending).It is well-known that the most efficient filtration is achieved with a relatively long but thin-walled filter element. For ...
