Abstract

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a main body defining a cooking chamber. The example pellet grill further includes a burn pot located within the main body. The burn pot includes an upper end, a lower end located opposite the upper end, and a sidewall extending between the upper end and the lower end. The sidewall has an opening. The example pellet grill further includes an ignitor extending into the burn pot through the opening of the sidewall. The example pellet grill further includes an ignitor carrier removably coupled to the ignitor. The ignitor carrier extends away from the burn pot and is accessible from outside the main body.

First claim

What is claimed is:

1. A pellet grill, comprising:
a main body defining a cooking chamber;
a housing coupled to the main body, the housing including a front wall and a rear wall located opposite the front wall, the front wall of the housing located within the main body, the rear wall of the housing located outside the main body, the rear wall of the housing including an opening;
a burn pot located within the main body, the burn pot carried by the housing and positioned at the front wall of the housing, the burn pot including an upper end, a lower end located opposite the upper end, and a sidewall extending between the upper end and the lower end, the sidewall having an opening;
an ignitor extending into the burn pot through the opening of the sidewall; and
an ignitor carrier removably coupled to the ignitor, the ignitor carrier including a first end configured to carry the ignitor, a second end located opposite the first end, and an arm extending between the first end and the second end, the first end oriented toward the front wall of the housing, the arm extending through the opening of the rear wall of the housing, the second end located outside the housing, the second end accessible from outside the main body.

2. The pellet grill of claim 1 , wherein the ignitor carrier is slidable relative to the burn pot to enable removal of the ignitor from the burn pot via the opening of the sidewall.

3. The pellet grill of claim 1 , wherein the ignitor carrier is slidable relative to the housing to enable removal of the ignitor from the housing via the opening of the rear wall of the housing.

4. The pellet grill of claim 1 , wherein the ignitor is a direct current (DC) powered glow plug.

5. The pellet grill of claim 1 , wherein the first end includes a connection socket configured to receive the ignitor.

6. The pellet grill of claim 1 , wherein the second end includes a tab configured to cover the opening of the rear wall of the housing.

7. The pellet grill of claim 1 , wherein the arm of the ignitor carrier extends rearwardly from the burn pot through a rear portion of an outer wall of the main body.

8. The pellet grill of claim 7 , further comprising a hopper mounted to the rear portion of the outer wall of the main body, the hopper including a rear wall having an opening, the opening of the rear wall of the hopper being selectively covered by an access door, the ignitor carrier being removable from the main body through the opening of the rear wall of the hopper when the access door is open, and while the hopper remains mounted to the main body.

9. The pellet grill of claim 1 , wherein the housing includes an ignitor carrier guide coupled to a bottom wall of the housing and located between the burn pot and the rear wall of the housing, the ignitor carrier guide configured to locate the ignitor carrier at a central position within the housing between a first sidewall and a second sidewall of the housing, the central position being aligned with the opening of the sidewall of the burn pot and further being aligned with the opening of the rear wall of the housing.

10. The pellet grill of claim 9 , wherein the bottom wall of the housing includes slots configured to receive flanges of the ignitor carrier guide.

11. The pellet grill of claim 1 , further comprising a fuel grate located within the burn pot between the upper end and the lower end, the fuel grate including an upper surface and a trough extending downwardly from the upper surface, the trough including an opening aligned with the opening of the sidewall, the ignitor extending away from the ignitor carrier, into the burn pot via the opening of the sidewall, and into the trough via the opening of the trough.

12. A pellet grill, comprising:
a main body defining a cooking chamber;
a housing coupled to the main body, the housing including a front wall and a rear wall located opposite the front wall, the front wall of the housing located within the main body, the rear wall of the housing located outside the main body, the rear wall of the housing including an opening;
a burn pot located within the main body, the burn pot carried by the housing and positioned at the front wall of the housing, the burn pot including an upper end, a lower end located opposite the upper end, and a sidewall extending between the upper end and the lower end, the sidewall having an opening;
an ignitor extending into the burn pot through the opening of the sidewall; and
an ignitor carrier removably coupled to the ignitor, the ignitor carrier extending rearwardly from the burn pot through a rear portion of an outer wall of the main body and through the opening of the rear wall of the housing, the ignitor carrier being accessible from outside the main body and outside the housing, the ignitor carrier being slidable relative to the burn pot to enable removal of the ignitor from the burn pot via the opening of the sidewall of the burn pot, the ignitor carrier further being slidable relative to the housing to enable removal of the ignitor from the housing via the opening of the rear wall of the housing.

13. The pellet grill of claim 12 , wherein the ignitor carrier includes a first end configured to carry the ignitor, a second end located opposite the first end, and an arm extending between the first end and the second end, the first end oriented toward the front wall of the housing, the arm extending through the opening of the rear wall of the housing, the second end located outside the housing, the second end accessible from outside the main body.

14. The pellet grill of claim 13 , wherein the ignitor is a direct current (DC) powered glow plug.

15. The pellet grill of claim 13 , wherein the first end includes a connection socket configured to receive the ignitor.

16. The pellet grill of claim 13 , wherein the second end includes a tab configured to cover the opening of the rear wall of the housing.

17. The pellet grill of claim 12 , further comprising a hopper mounted to the rear portion of the outer wall of the main body, the hopper including a rear wall having an opening, the opening of the rear wall of the hopper being selectively covered by an access door, the ignitor carrier being removable from the main body through the opening of the rear wall of the hopper when the access door is open, and while the hopper remains mounted to the main body.

18. The pellet grill of claim 12 , wherein the housing includes an ignitor carrier guide coupled to a bottom wall of the housing and located between the burn pot and the rear wall of the housing, the ignitor carrier guide configured to locate the ignitor carrier at a central position within the housing between a first sidewall and a second sidewall of the housing, the central position being aligned with the opening of the sidewall of the burn pot and further being aligned with the opening of the rear wall of the housing.

19. The pellet grill of claim 18 , wherein the bottom wall of the housing includes slots configured to receive flanges of the ignitor carrier guide.

20. The pellet grill of claim 12 , further comprising a fuel grate located within the burn pot between the upper end and the lower end, the fuel grate including an upper surface and a trough extending downwardly from the upper surface, the trough including an opening aligned with the opening of the sidewall, the ignitor extending away from the ignitor carrier, into the burn pot via the opening of the sidewall, and into the trough via the opening of the trough.
