ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to gray-water reclamation systems and more particularly pertains to a new gray-water recycling system for reclaiming gray-water for use in toilets and lawn care.
2. Description of the Prior Art
The use of gray-water reclamation systems is known in the prior art. More specifically, gray-water reclamation systems heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.
Known prior art includes U.S. Pat. No. 5,106,493; U.S. Pat. No. 5,317,766; U.S. Pat. No. 4,145,279; U.S. Pat. No. 5,406,657; U.S. Pat. No. 4,162,218; and U.S. Pat. No. 3,915,857.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new gray-water recycling system. The inventive device includes a reservoir, which is adapted to treat gray-water. The reservoir has an intake pipe, an outlet pipe and an overflow pipe. An inlet supplies gray-water to the reservoir. The inlet is fluidly coupled to the intake pipe. A filtering means filters the gray-water. The filtering means is fluidly coupled to the outlet pipe. The gray-water is filtered through the filter such that the filtered water is defined as processed gray-water. A pumping means draws the gray-water through the filtering means. The pumping means is fluidly coupled to the filtering means by a pipe. A first valve controls flow of the processed gray-water from the pumping means. The first valve has a first end, a second end and middle section. The first end is fluidly coupled to the pumping means by a pipe. The second end is fluidly coupled to a fresh water inlet. A middle section of the first valve is fluidly coupled to a processed gray-water outlet. The first valve is adapted to open the fresh water if the water pressure from the processed gray-water falls.
In these respects, the gray-water recycling system according to the present invention substantially departs from the conventional concepts and designs of the prior art, and in so doing provides an apparatus primarily developed for the purpose of reclaiming gray-water for use in toilets and lawn care.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of gray-water reclamation systems now present in the prior art, the present invention provides a new gray-water recycling system construction wherein the same can be utilized for reclaiming gray-water for use in toilets and lawn care.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new gray-water recycling system apparatus and method which has many of the advantages of the gray-water reclamation systems mentioned heretofore and many novel features that result in a new gray-water recycling system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art gray-water reclamation systems, either alone or in any combination thereof.
To attain this, the present invention generally comprises a reservoir, which is adapted to treat gray-water. The reservoir has an intake pipe, an outlet pipe and an overflow pipe. An inlet supplies gray-water to the reservoir. The inlet is fluidly coupled to the intake pipe. A filtering means filters the gray-water. The filtering means is fluidly coupled to the outlet pipe. The gray-water is filtered through the filter such that the filtered water is defined as processed gray-water. A pumping means draws the gray-water through the filtering means. The pumping means is fluidly coupled to the filtering means by a pipe. A first valve controls flow of the processed gray-water from the pumping means. The first valve has a first end, a second end and middle section. The first end is fluidly coupled to the pumping means by a pipe. The second end is fluidly coupled to a fresh water inlet. A middle section of the first valve is fluidly coupled to a processed gray-water outlet. The first valve is adapted to open the fresh water if the water pressure from the processed gray-water falls.
There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.
In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting.
As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present inventions It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
Further, the purpose of the foregoing abstract is to enable the U.S. Patent and Trademark Office and the public generally, and especially the scientists, engineers and practitioners in the art who are not familiar with patent or legal terms or phraseology, to determine quickly from a cursory inspection the nature and essence of the technical disclosure of the application. The abstract is neither intended to define the invention of the application, which is measured by the claims, nor is it intended to be limiting as to the scope of the invention in any way.
It is therefore an object of the present invention to provide a new gray-water recycling system apparatus and method which has many of the advantages of the gray-water reclamation systems mentioned heretofore and many novel features that result in a new gray-water recycling system which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art gray-water reclamation systems, either alone or in any combination thereof.
It is another object of the present invention to provide a new gray-water recycling system which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new gray-water recycling system which is of a durable and reliable construction.
An even further object of the present invention is to provide a new gray-water recycling system which is susceptible of a low cost of manufacture with regard to both materials and labor, and which accordingly is then susceptible of low prices of sale to the consuming public, thereby making such gray-water recycling system economically available to the buying public.
Still yet another object of the present invention is to provide a new gray-water recycling system which provides in the apparatuses and methods of the prior art some of the advantages thereof, while simultaneously overcoming some of the disadvantages normally associated therewith.
Still another object of the present invention is to provide a new gray-water recycling system for reclaiming gray-water for use in toilets and lawn care.
Yet another object of the present invention is to provide a new gray-water recycling system which includes a reservoir, which is adapted to treat gray-water. The reservoir has an intake pipe, an outlet pipe and an overflow pipe. An inlet supplies gray-water to the res
