Residential fireplace insert system improvements

Abstract

This CIP titled “Residential Fireplace Insert System Improvements” involves an improvement in the efficiency of the slide-in “Residential Woodburning Fireplace Insert System”, formerly application Ser. No. 11 / 507,343 filed Aug. 21, 2006, (now Pat. No. 7,509,954) wherein the heat output and fuel consumption are improved by controllably shutting off free air flow into the the combustion chamber by using a framed panel of heat-tolerant plastic film (as an alternate to using the glass doors) at the surround door location, then controlling the generated heat and fuel combination by carefully injecting just the proper ratio of the oxygen-to-fuel necessary for controlling both the heat output rate and fuel consumption parameters which include soot and creosote control improvements.

Description

CROSS REFERENCE This Sub-Spec Contains No New Matter[0001]This application is a Continuation-In-Part to: “Residential Fireplace Insert System”, (Pat. No. 7,509,954).FIELD OF THE INVENTION[0002]These improvements relate to the normal advancements, innovations and improvements discovered during the almost three-year period the parent application was wending its way through the examination process. In few words these discoveries center around a modification to the bifold glass door closure area, supplementary air controls within the heat combustion area, modification for soot and creosote control and a dome light mounted to the under-underside of the tubing air manifold for close observation of needed fine adjustments.BACKGROUND OF THE INVENTION[0003]The “Continuation-In-Part” will be described with reference to the Parent application Ser. No. 11 / 507,343 filed Jun. 6, 2008, but persons skilled in the art will recognize the continuation in part where improvement in the art is effected.P...

AI Technical Summary

Problems solved by technology

During the nearly three-year period of time the parent application was going through the examination period, testing and evaluations were constant challenges to obtain the optimum target conditions for fireplace efficiency.

Early on, it became evident that the “standard” door closures of the industry were woefully inefficient.

All models “leaked” air volumes into the combustion chamber with no real heat or fuel consumption controls.

Therefore, the longer the churning of heated air, the better is the chance the moisture can be driven off and the dried-out carbon dust particle component might be exhausted up the chimney.

If this occurs and the water evaporation takes place, the result is a “baked-on” soot deposit which is quite difficult to remove.
