DETAILED DESCRIPTION OF THE INVENTION

[0029] While this invention may be embodied in many forms, there are described in detail herein specific embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.

[0030] For the purposes of this disclosure, like reference numerals in the Figures shall refer to like features unless otherwise indicated.

[0031] Referring now to FIG. 1, an embodiment of an inventive water filter is shown generally at 10 in a perspective view showing the bottom, right and front sides of the water filter. The parts of the water filter are shown slid apart and it should be understood that the carbon elements 12 and 14 are each about 4 inches long and the entire water filter, when slid together is about 8 inches long. One end of the water filter 10 has an inlet 16 and an outlet 18. The inlet water is split and runs into each carbon element near its outer diameter and the water flows down the inside of the casing holding the carbon, and back up through the center and out of the carbon element, to be recombined and flow out the outlet 18 (see FIG. 11). The end cap and tray section 20 can slide out so permit the replaceable carbon elements to be removed and replaced with fresh carbon elements.

[0032] Referring now to FIG. 2, a perspective view showing the top, back and left sides of the water filter is shown.

[0033] Referring now to FIG. 3, a right side view of the water filter is shown.

[0034] Referring now to FIG. 4, a back view of the water filter is shown.

[0035] Referring now to FIG. 5, a left view of the water filter is shown.

[0036] Referring now to FIG. 6, a top view of the water filter is shown.

[0037] Referring now to FIG. 7, a back side view of the water filter is shown.

[0038] Referring now to FIG. 8, a bottom view of the water filter is shown.

[0039] Referring now to FIG. 9, an exploded view of the water filter components are shown.

[0040] Referring now to FIG. 10, a section view of the water filter is shown.

[0041] Referring now to FIG. 11, a water flow diagram is shown, in which water is shown flowing through the inlet, is split into two streams and showing the water flowing down the outside inner portion of the carbon element and back up through the center of the element, to recombine and flow out the water outlet. The four arrow shapes 22, schematically show piercings which are made when the carbon elements are slid into place in the water filter, to permit water to flow into and out of each carbon element.

[0042] Referring now to FIG. 12, the end cap is shown with a timer component shown at 24. FIG. 13 shows that the timer component consists of a timer circuit 26 for measuring either the elapsed time, which can be any predetermined interval, such as 3 months or 6 months, a power source 28 such as a lithium camera battery and an indicator 30 for indicating when the predetermined time interval has elapsed. A reset button in shown at 32 in FIG. 12 to reset the timer circuit.

[0043] The indicator can be an LED light, which can be configures to shine on the floor in front of the refrigerator, or it can be configured to blink. The indicator can also be a Bluetooth transmitter which can transmit a message to a paired smartphone or even automatically reorder carbon elements via a product such as an amazon echo. In addition, the indicator could be a WIFI transmitter which can perform the same functions as described with the Bluetooth option.

[0044] Referring now to FIG. 14, the carbon element can also include a section 32 which can hold either a volume measuring device, a water additive or both. The water volume measuring device could be electrically connected to the timer circuit 26 so the indicator 30 can be triggered by a predetermined volume of water passing through the water filter, rather than using elapsed time. The water additive could add flavors to the water as it is filtered, or vitamins, nutraceuticals and/or electrolytes, or any combination thereof.

[0045] The above disclosure is intended to be illustrative and not exhaustive. This description will suggest many variations and alternatives to one of ordinary skill in this field of art. All these alternatives and variations are intended to be included within the scope of the claims where the term “comprising” means “including, but not limited to.” Those familiar with the art may recognize other equivalents to the specific embodiments described herein which equivalents are also intended to be encompassed by the claims.

[0046] Further, the particular features presented in the dependent claims can be combined with each other in other manners within the scope of the invention such that the invention should be recognized as also specifically directed to other embodiments having any other possible combination of the features of the dependent claims. For instance, for purposes of claim publication, any dependent claim which follows should be taken as alternatively written in a multiple dependent form from all prior claims which possess all antecedents referenced in such dependent claim if such multiple dependent format is an accepted format within the jurisdiction (e.g. each claim depending directly from claim 1 should be alternatively taken as depending from all previous claims). In jurisdictions where multiple dependent claim formats are restricted, the following dependent claims should each be also taken as alternatively written in each singly dependent claim format which creates a dependency from a prior antecedent-possessing claim other than the specific claim listed in such dependent claim below.

[0047] This completes the description of the preferred and alternate embodiments of the invention. Those skilled in the art may recognize other equivalents to the specific embodiment described herein which equivalents are intended to be encompassed by the claims attached hereto.
