ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to heater core preheaters and more particularly pertains to a new heater core preheater for allowing a user to quickly and efficiently receive heat in a vehicle in cold weather conditions.
2. Description of the Prior Art
The use of heater core preheaters is known in the prior art. More specifically, heater core preheaters 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. Nos. 4,575,003; 4,862,951; 5,183,099; 5,522,453; 3,888,412; Des. 386,561.
While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new heater core preheater. The inventive device includes a housing that has a body portion such that the housing is adapted for coupling to a heater hose between an engine of the vehicle and an inlet of the heater core of the vehicle. A heating element is coupled within the housing such that the heating element is adapted for heating fluid flowing through the heater hose to the heater core. A switch is operationally coupled between the heating element and a power source of the vehicle such that actuation by the user of the switch provides the heating element with power.
In these respects, the heater core preheater 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 allowing a user to quickly and efficiently receive heat in a vehicle in cold weather conditions.
SUMMARY OF THE INVENTION
In view of the foregoing disadvantages inherent in the known types of heater core preheaters now present in the prior art, the present invention provides a new heater core preheater construction wherein the same can be utilized for allowing a user to quickly and efficiently receive heat in a vehicle in cold weather conditions.
The general purpose of the present invention, which will be described subsequently in greater detail, is to provide a new heater core preheater apparatus and method which has many of the advantages of the heater core preheaters mentioned heretofore and many novel features that result in a new heater core preheater which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art heater core preheaters, either alone or in any combination thereof.
To attain this, the present invention generally comprises a housing that has a body portion such that the housing is adapted for coupling to a heater hose between an engine of the vehicle and an inlet of the heater core of the vehicle. A heating element is coupled within the housing such that the heating element is adapted for heating fluid flowing through the heater hose to the heater core. A switch is operationally coupled between the heating element and a power source of the vehicle such that actuation by the user of the switch provides the heating element with power.
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 invention. 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 heater core preheater apparatus and method which has many of the advantages of the heater core preheaters mentioned heretofore and many novel features that result in a new heater core preheater which is not anticipated, rendered obvious, suggested, or even implied by any of the prior art heater core preheaters, either alone or in any combination thereof.
It is another object of the present invention to provide a new heater core preheater, which may be easily and efficiently manufactured and marketed.
It is a further object of the present invention to provide a new heater core preheater, which is of a durable and reliable construction.
An even further object of the present invention is to provide a new heater core preheater 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 heater core preheater economically available to the buying public.
Still yet another object of the present invention is to provide a new heater core preheater 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 a new heater core preheater for allowing a user to quickly and efficiently receive heat in a vehicle in cold weather conditions.
Yet another object of the present invention is to provide a new heater core preheater which includes a housing that has a body portion such that the housing is adapted for coupling to a heater hose between an engine of the vehicle and an inlet of the heater core of the vehicle. A heating element is coupled within the housing such that the heating element is adapted for heating fluid flowing through the heater hose to the heater core. A switch is operationally coupled between the heating element and a power source of the vehicle such that actuation by the user of the switch provides the heating element with power.
Still yet another object of the present invention is to provide a new heater core preheater that would make the first few minutes in a cold vehicle more comfortable for the driver and the passengers. The pleasant temperature would allow the driver to concentrate on driving so accidents could be avoided.
Even still another object of the present invention is to provide a new heater core preheater that would allow the user to defrost the windows much faster than with a conventional heating system.
These together with other objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. For a better
