Energy efficient, safe, customizable stovetop system

Abstract

A stovetop system comprising a stovetop, wound around a burner, supports a vessel to be heated. The hot gas from the burner is guided through an extended path under the vessel's bottom to improve the heating efficiency of a stove on which this standalone stovetop system is installed. Improvements in safety, vessel adaptability, and automatic temperature control of the heating process are also achieved.

1 - 7 . (canceled) 
     
     
         8 . An energy-efficient, customizable stovetop system comprising:
 at least one stovetop ( 11 ) wound a plurality of times with continuous space between the windings around a hot gas source to support a vessel substantially aligned with the hot gas source, with its bottom surface in contact with the edge of the windings to create a path bound by the windings on the sides and said vessel's bottom surface on the top for the hot gas to flow thereby increasing the contact time of the hot gas with said vessel manyfold compared to the contact time along a guided or unguided radial path under said vessel thereby increasing the heating efficiency;   and an exhaust system ( 20 ) comprising an outlet located away from the stovetop surrounding, outside the room of the stovetop, and dispose hot gas from an inlet ( 21 ) located at the end of or anywhere in the space between the windings at the periphery of said vessel thereby adapting to the vessel's size, drawing all the hot gas with harmful chemicals away from the stovetop, not heating the stovetop surrounding and preventing the hot gas from coming in contact with flammable fumes from the contents of the vessel that can result in a fire incident.   
     
     
         9 . The energy-efficient, customizable stovetop system of  claim 8 , further comprises risers ( 16 ) installed on the stovetop ( 11 ) windings biased upward by springs to close gaps between the stovetop ( 11 ) windings and the bottom surface of a vessel thereby confining the hot gas in the winding path. 
     
     
         10 . An energy-efficient, customizable stovetop system comprising:
 at least one stovetop ( 11 ) wound a plurality of times with continuous space between the windings around a hot gas source to support a vessel substantially aligned with the hot gas source, with its bottom surface in contact with the edge of the windings to create a path bound by the windings on the sides and said vessel's bottom surface on the top for the hot gas to flow thereby increasing the contact time of the hot gas with said vessel manyfold compared to the contact time along a guided or unguided radial path under said vessel thereby increasing the heating efficiency;   an exhaust system ( 20 ) comprising an outlet located away from the stovetop surrounding, outside the room of the stovetop, and dispose hot gas from an inlet ( 21 ) located at the end of or anywhere in the space between the windings at the periphery of said vessel thereby adapting to the vessel's size, drawing all the hot gas with harmful chemicals away from the stovetop, not heating the stovetop surrounding and preventing the hot gas from coming in contact with flammable fumes from the contents of the vessel that can result in a fire incident;   and a control system comprising a computer processor with software to control the hot gas temperature at said inlet ( 21 ) by operating a valve supplying fuel to said burner based on the input from a temperature sensor located at said input ( 21 ) and the operating parameters set in the software program thereby controlling the heating of the vessel.
