supply to individual burner jets, said range burner comprising: a
burner body formed as a closed loop defining an open central area,
said burner body having a plurality of gas passageways formed
therein, a burner top disposed on said burner body and including
burner jets in communication with said gas passageways, and a
burner bottom having an exhaust opening, said burner bottom being
disposed on said burner body oppositely from said burner top, with
said open central area of said burner body being in registry with
said exhaust opening and extending between said burner top and said
burner bottom; and a flue mounted to said burner bottom and
projecting outwardly therefrom, said flue being in fluid
communication with said exhaust opening for drawing exhaust gases
from said open central area of said burner body.
2. The infrared range burner according to claim 1 wherein said flue
has a generally circular cross section.
3. The infrared range burner according to claim 1 wherein said flue
has a generally flat sided cross section.
Description
BACKGROUND OF THE INVENTION
[0001] The present invention is related broadly to cooktops having
infrared gas burners including barbeque grills and, more
particularly to an infrared gas burner having an exhaust gas
flue.
[0002] Infrared burners work by focusing the flame of a standard
gas burner onto a ceramic tile having thousands of microscopic
holes in it. This converts the heat of the flame into infrared,
radiant energy. The heat energy is much greater and more persistent
than a standard grill can produce. Infrared burners can reach
cooking temperatures greater than 1800 degrees Fahrenheit.
[0003] Some infrared burners include burner bodies formed as a
perimetorial structure or a loop, be it round, square or other
closed loop shape. Such closed loop burners define an open central
area in the middle of the burner. Often, unburned gas and
combustion residue can collect in the atmosphere in the center of
the burner. It would be advantageous to evacuate the central area
as quickly and efficiently as possible in order to diminish the
uncertain influence on the cooking process of collected combustion
gasses and other combustion residue in the central area.
SUMMARY OF THE INVENTION
[0004] It is accordingly an object of the present invention to
provide an infrared burner having an efficient apparatus for
evacuating the waste gasses from the central area.
[0005] To that end, an infrared range burner having a plurality of
gas passageways formed therein for delivering combustion gas from a
central gas supply to individual burner jets includes a burner body
formed as a closed loop defining an open central area, the burner
body having a plurality of gas passageways formed therein; a burner
top disposed on the burner body and including burner jets in
communication with the gas passageways; a burner bottom having an
exhaust opening formed in a central area thereof, the burner bottom
being disposed on the burner body oppositely from the burner top,
with the open central area in registry with the exhaust opening and
extending between the burner top and the burner bottom; and a flue
mounted to the burner bottom and projecting outwardly therefrom,
the flue being in fluid communication with the exhaust opening for
drawing exhaust gases from the open central area. The present
invention also includes an infrared range burner wherein the flue
has a generally circular cross section and an infrared range burner
wherein the flue has a generally flat sided cross section.
BRIEF DESCRIPTION OF THE DRAWINGS
[0006] FIG. 1 is a top perspective view of an infrared burner
according to one preferred embodiment of the present invention;
[0007] FIG. 2 is a bottom perspective view of the infrared burner
illustrated in FIG. 1;
[0008] FIG. 3 is a top perspective view of an infrared burner
according to another preferred embodiment of the present invention;
and
[0009] FIG. 4 is a bottom perspective view of the infrared burner
illustrated in FIG. 3.
DESCRIPTION OF THE PREFERRED EMBODIMENT
[0010] Turning now to the drawings and, more particularly to FIG.
1, an infrared burner is illustrated generally at 10 and includes a
generally circular burner body 12 having a burner top 16 and a
burner bottom 17 attached thereto as seen in FIGS. 1 and 2. The
result is a washer-like structure with tapered side walls wherein
the major and minor diameters of the burner top 16 are larger than
the major and minor diameters of the burner bottom 17. A gas feed
pipe 14 projects outwardly from one portion of the burner body 12.
The burner body 12 defines gas passageways therein (not shown).
[0011] A central area 18 is defined by the central openings within
the burner top 16 and burner bottom 17. The opening of the burner
bottom 17 is an exhaust opening 20. Walls 22 are formed on the
inside of the central area and are tapered from the larger central
area opening to the smaller exhaust opening 20. The walls 22 of the
central area 18 act like a nozzle and if a draft is drawn through
the central area, aid in the evacuation of the unwanted gasses in
the central area.
[0012] Turning again to FIG. 1, according to the present invention,
a flue 24 is attached to the bottom portion 17 of the burner 10
adjacent and surrounding the exhaust opening 20. The flue 24
projects away from the burner bottom 17. The cross section of the
flue 20 is a circle making the flue itself a cylinder.
[0013] Turning now to FIGS. 3 and 4, a second preferred embodiment
of the present invention is illustrated therein. As seen in FIGS. 3
and 4, the burner structure is essentially a square whereas in
FIGS. 1 and 2 the burner structure is essentially a circle.
[0014] Accordingly, the walls 22 of the central area 18 are angled
with respect to one another yet the evacuation of the central area
remains substantially the same process as in the first
embodiment.
[0015] Turning now to FIG. 4, the flue 24 is once again attached to
the burner bottom 17 and projects away therefrom. According to the
second preferred embodiment of the present invention, the cross
section of the flue 24 may include several angular areas and the
flue 24 structure may include several flat panels. Accordingly, the
flue 24 can be a multisided structure.
[0016] By the above, the present invention provides an economical,
mechanical structure for evacuating unwanted gasses and unburned
matter from an open central area of an infrared burner.
[0017] It will therefore be readily understood by those persons
skilled in the art that the present invention is susceptible of a
broad utility and application. While the present invention is
described in all currently foreseeable embodiments, there may be
other, unforeseeable embodiments and adaptations of the present
invention, as well as variations, modifications and equivalent
arrangements, that do not depart from the substance or scope of the
present invention. The foregoing disclosure is not intended or to
be construed to limit the present invention or otherwise to exclude
such other embodiments, adaptations, variations, modifications and
equivalent arrangements, the present invention being limited only
by the claims appended hereto and the equivalents thereof.
