Abstract

Burner tubes for gas grills are disclosed. An example burner tube includes an open front end, a closed rear end located opposite the open front end, opposing upper and lower surfaces extending between the open front end and the closed rear end, opposing right and left side surfaces extending between the upper surface and the lower surface and between the open front end and the closed rear end, and a hollow interior defined by the upper surface, the lower surface, the right side surface, and the left side surface. The hollow interior has a rectangular cross-sectional profile that tapers in a direction moving from the open front end toward the closed rear end. The burner tube further includes a plurality of gas ports extending upwardly from the upper surface, with each one of the gas ports having an exit opening raised above the upper surface.

an air shutter disposed externally from and slidably coupled to the linear burner tube proximate the open front end of the linear burner tube, the air shutter including:

an upper surface;

a right side surface extending downwardly from a right edge of the upper surface of the air shutter, the right side surface of the air shutter including a first open region configured to communicate with a first window formed in the right side surface of the linear burner tube; and

a left side surface extending downwardly from a left edge of the upper surface of the air shutter, the left side surface of the air shutter including a second open region configured to communicate with a second window formed in the left side surface of the linear burner tube.

2. The burner assembly of claim 1 , wherein the linear burner tube includes a first hole formed in the upper surface of the linear burner tube and the air shutter includes a slot formed in the upper surface of the air shutter, the slot coaxially aligned with the first hole such that a fastener can extend through the slot and through the first hole to couple the air shutter to the linear burner tube.

3. The burner assembly of claim 2 , wherein the slot enables adjustment of the air shutter relative to the first window and the second window, wherein the air shutter is slidable relative to the first window and the second window along a longitudinal axis of the linear burner tube, the longitudinal axis extending between the open front end and the closed rear end of the linear burner tube.

4. The burner assembly of claim 3 , further comprising a gas valve receiver disposed within the hollow interior of the linear burner tube proximate the open front end of the linear burner tube, the gas valve receiver including:

a front face having an opening configured to receive a neck of a gas valve;

an upper flange extending rearwardly from an upper edge of the front face; and

a lower flange extending rearwardly from a lower edge of the front face, the lower flange being parallel to the upper flange.

5. The burner assembly of claim 4 , wherein the gas valve receiver includes a second hole formed in the upper flange of the gas valve receiver, the second hole coaxially aligned with the first hole of the upper surface of the linear burner tube and the slot of the upper surface of the air shutter such that the fastener can extend through the slot, through the first hole, and through the second hole to couple the air shutter to the linear burner tube and the gas valve receiver.

6. The burner assembly of claim 1 , wherein the linear burner tube further includes a tab extending downwardly from the lower surface between the open front end and the closed rear end.

7. The burner assembly of claim 1 , wherein the hollow interior of the linear burner tube is free from burrs or other obstructions.

8. The burner assembly of claim 1 , wherein each one of the gas ports has a height projecting above the upper surface of the linear burner tube, and the exit opening of each one of the gas ports has a diameter, wherein a ratio of the height to the diameter is greater than 0.5.

9. The burner assembly of claim 1 , wherein each one of the gas ports has a height projecting above the upper surface of the linear burner tube, and the exit opening of each one of the gas ports has a diameter, wherein a ratio of the height to the diameter is between 0.625 and 0.670.

10. The burner assembly of claim 1 , wherein each one of the gas ports has a height projecting above the upper surface of the linear burner tube, and the exit opening of each one of the gas ports has a diameter, wherein the height is between 0.020 inches and 0.062 inches and the diameter is between 0.075 inches and 0.110 inches.

11. A burner assembly, comprising:

a linear burner tube including:

an open front end;

a closed rear end located opposite the open front end;

an upper surface extending between the open front end and the closed rear end, the upper surface including a first hole formed therein and located proximate the open front end;

a lower surface located opposite the upper surface and extending between the open front end and the closed rear end;

a right side surface extending between the upper surface and the lower surface, the right side surface extending between the open front end and the closed rear end;

a left side surface located opposite the right side surface and extending between the upper surface and the lower surface, the left side surface extending between the open front end and the closed rear end;

a hollow interior defined by the upper surface, the lower surface, the right side surface, and the left side surface, the hollow interior having a rectangular cross-sectional profile that tapers in a direction moving from the open front end toward the closed rear end; and

a plurality of gas ports extending upwardly from the upper surface, each one of the gas ports having an exit opening raised above the upper surface;

a gas valve receiver disposed within the hollow interior of the linear burner tube proximate the open front end of the linear burner tube, the gas valve receiver including:

a front face having an opening configured to receive a neck of a gas valve;

an upper flange extending rearwardly from an upper edge of the front face, the upper flange including a second hole formed therein, the second hole coaxially aligned with the first hole such that a fastener can extend through the first hole and through the second hole to couple the gas valve receiver to the linear burner tube; and

a lower flange extending rearwardly from a lower edge of the front face, the lower flange being parallel to the upper flange; and

an air shutter disposed externally from and slidably coupled to the linear burner tube proximate the open front end of the linear burner tube, the air shutter including:
