Description
- Applicant claims the benefit of U.S. Provisional Application No. 60/754,298 filed on Dec. 29, 2005.
- 1. Field of Invention
- This invention relates to a tube burner for use with a flammable gas supply of a barbecue grill. The tube burner has a venturi tube containing a venturi extending a substantial distance into a burner tube and to a method of construction thereof.
- 2. Description of the Prior Art
- Tube burners are known with a venturi located at an inlet end of a burner tube. The venturi is open to a downstream end of the burner tube and as well has an opening at an upstream end. The venturi is located in a venturi tube. The upstream end has a connector thereon to connect the tube burner to a flammable gas supply. The burner tube has a plurality of openings of equal size along each side. The venturi has an air inlet at the upstream end to allow gas and air entering the venturi to mix in the appropriate proportions so that the gas/air mixture is flammable. The tube burner has a single wall. The gas/air mixture exiting from the plurality of openings in the burner tube is combustible for those openings that are not close to the upstream end. The openings near the upstream end do not produce a usable flame.
- When the previous tube burners are used in a barbecue grill, (also known as a gas barbecue), difficulty has been encountered in providing a tube burner that will burn efficiently and evenly throughout its length. When the venturi tube is located at the inlet end of the burner tube, the tube burner often burns unevenly. The openings in the side of the burner tube near the upstream end do not produce a usable flame.
- It is an object of the present invention to provide a tube burner in which even burning is achieved throughout the length of the tube burner. It is a further object of the present invention to provide a tube burner in which a venturi tube is substantially embedded in a burner tube of the tube burner.
- A tube burner is used with a flammable gas supply, the burner comprising a burner tube and a venturi tube. The venturi tube has a venturi therein, the venturi tube extending from the venturi into the burner tube. The burner is connected to the gas supply and has an air inlet upstream of the venturi. There is a passage connecting the gas supply and the air inlet to the venturi. The venturi tube has at least one opening therein within the burner tube for a gas/air mixture to pass into the burner tube. The burner tube has a plurality of openings along each side thereof through which the gas/air mixture entering the burner tube from the venturi tube can escape for combustion.
- A tube burner is used with a flammable gas supply for a barbecue grill. The burner comprises a top, bottom and two sides and has a venturi tube and a burner tube. The venturi tube is concentrically mounted partially within the burner tube. The venturi tube has a venturi therein and has a connector at an outer end for connection to the gas supply. The outer end has an air inlet and the venturi tube terminates partly along the length of the burner tube. The venturi tube has at least one opening therein downstream from the venturi, the at least one opening being located within the burner tube. The burner tube has a plurality of openings along each side thereon through which the gas/air mixture entering the burner tube from the venturi can escape for combustion.
- A tube burner is used with a flammable gas supply, the burner comprising two ends and two sides and having a venturi tube and a burner tube. The venturi tube is concentrically mounted substantially within the burner tube, the venturi tube having at least one opening therein within the burner tube. The venturi tube has a venturi therein and has a connector at an outer end for connection to the gas supply. The outer end has an air inlet. The burner tube has a plurality of openings along the side thereof through which a gas/air mixture entering the burner tube from the venturi tube can escape for combustion.
- A method of constructing a tube burner for use with a barbecue grill and a flammable gas supply uses a burner having a burner tube and a venturi tube. The method comprises mounting the venturi tube at least partially within the burner tube at an upstream end of the burner tube. The venturi tube has an air inlet and a connector for connecting the outer end to the gas supply. The method further comprises installing at least one opening in that part of the venturi tube located within the burner tube and installing a plurality of openings along each side of the burner tube through which a gas/air mixture entering the burner tube from the venturi tube can escape.

FIG. 1 is a top view of a tube burner of the present invention; -
FIG. 2 is a partial sectional view along the lines A-A ofFIG. 1 ; -
FIG. 3 is a side view of the tube burner; -
FIG. 4 is a perspective view of the tube burner; -
FIG. 5 is an end view of the tube burner from an upstream end; -
FIG. 6 is a schematic top view of a venturi tube; -
FIG. 7 is a schematic bottom view of the venturi tube; and -
FIG. 8 is a side view of a Prior Art burner. - In
FIGS. 1 and 2 , it can be seen that atube burner 2 has aventuri tube 4 concentrically mounted partially within aburner tube 6. The burner tube and venturi tube are concentrically mounted relative to one another. Theventuri tube 4 has a venturi (not shown) therein, which is conventional. Theventuri tube 4 has aconnector 8 at anouter end 10 of theventuri tube 4. Anair inlet 12 has a screen thereon with anadjustable cover 14 that can be moved to cover or expose more of theair inlet 12 by removing and appropriately reinserting ascrew 16. Preferably, the screen is a stainless steel mesh. The burner tube is crimped to fit onto the venturi tube and the venturi tube and burner tube are spot welded and sealed together at anupstream end 18 of theburner tube 6. Adownstream end 20 of theburner tube 6 is closed. InFIG. 2 , it can be seen that theventuri tube 4 extends substantially into theburner tube 6. Preferably, substantially two-thirds of a length of said venturi tube is located inside of said burner tube. - As best seen in
FIGS. 2 and 3 , theburner tube 6 has a plurality ofopenings 22 along each side thereof. Theopenings 22 near theupstream end 18 are larger than theopenings 22 at thedownstream end 20 of theburner tube 6. Theopenings 22 get progressively smaller from theupstream end 18 to thedownstream end 20.FIG. 4 is a perspective view of thetube burner 2 andFIG. 5 is an end view from an entrance to theventuri tube 4. The same reference numerals are used inFIGS. 3 , 4 and 5 as those used inFIGS. 1 and 2 to describe those components that are identical. - In
FIG. 6 , there is shown a schematic top view of theventuri tube 4 with a plurality ofopenings 24 therein. InFIG. 7 , there is shown a bottom view of theventuri tube 4 with a plurality of openings 26 therein. Theopenings 24, 26 are located in that portion of theventuri tube 4 that is mounted within theburner tube 6 and is downstream from aventuri 27. The same reference numerals are used inFIGS. 6 and 7 as those used inFIGS. 1 and 2 for those components that are identical. It can be seen inFIG. 2 that the upper and lower edges of theventuri tube 4 have a plurality of depressions therein. While theopenings 24, 26 are not shown inFIG. 2 , the openings are located at those depressions. - The
tube burner 2 has substantially the same length as a prior art tube burner (seeFIG. 8 ), but the prior art tube burner does not provide even heat and often has several side openings near the upstream end where no usable flame is produced. Thetube burner 2 operates more efficiently in that the heat generated at each of theopenings 22 is substantially equal. With previous tube burners, where the venturi is located at the entrance to the burner tube, the openings in the burner tube near the upstream end do not produce the same heat as the openings in the downstream end. In fact, many of the openings in the upstream end do not even produce a flame. The gas mixes much faster with the air over a shorter distance with the tube burner of the present invention than with the prior art tube burners. The priorart tube burner 20, has aburner tube 32 with aventuri 34 at anentrance 36 thereof. Anair inlet 38 is located upstream of the venturi. The gas supply (not shown) is connected to theair inlet 40 of theburner 2. The tube burner has a plurality ofopenings 42 along each side. - The tube burner is constructed by mounting the venturi tube at least partially within the burner tube and preferably substantially within the burner tube.
