Abstract

A grill stove includes a kettle, legs, and a lid. The kettle includes an outer wall with a ventilation aperture, an inner wall, and a top collar extending between the inner wall and the outer wall and connecting the top portion of the outer wall to the top portion of the inner wall to form a dual-walled kettle. A base pan may be attached to the outer wall and may form a bottom of the kettle. A nest pan may have an edge and a ventilation aperture. The edge of the nest pan may be attached to the bottom portion of the inner wall and disposed above the base pan. The nest pan and the base pan being spaced apart to form a gap therebetween. The ventilation aperture of the nest pan may be in fluid communication with the ventilation aperture of the outer wall. An ash pan may be removably positionable above the nest pan.

First claim

What is claimed is:

1. A grill stove, comprising:
a kettle comprising:
an outer wall including a top portion with a top edge, a bottom portion width a bottom edge, and a ventilation aperture,
an inner wall including a top portion with a top edge and a bottom portion with a bottom edge,
a top collar extending between the inner wall and the outer wall, the top collar connecting the top portion of the outer wall to the top portion of the inner wall, the inner wall and the outer wall being spaced apart to form a gap therebetween,
a base pan attached to the outer wall and forming a bottom of the kettle, and
a nest pan having an edge and a ventilation aperture, the edge of the nest pan being attached to the bottom portion of the inner wall and disposed above the base pan, the nest pan and the base pan being spaced apart to form a gap therebetween, the ventilation aperture of the nest pan being in fluid communication with the ventilation aperture of the outer wall;

an ash pan removably positionable above the nest pan; and
a coal grate removably disposed above the ash pan and the nest pan.

2. The grill stove of claim 1 , wherein the inner wall further includes a top lip positioned at an outer perimeter of the top collar.

3. The grill stove of claim 1 , wherein a height of the inner wall is less than a height of the outer wall, and wherein the ventilation aperture of the outer wall comprises a plurality of apertures positioned within the outer wall at an elevation lower than the bottom edge of the inner wall.

4. The grill stove of claim 1 , wherein the ventilation aperture of the nest pan comprises a central opening in a bottom surface of the nest pan.

5. The grill stove of claim 1 , wherein at least one of the ash pan, the nest pan, or the base pan includes radial embossed features.

6. The grill stove of claim 5 , wherein at least some of the radial embossed features are configured to nest with features of a grill stand.

7. The grill stove of claim 1 , wherein the outer wall, inner wall, base pan, nest pan, ash pan, and coal grate comprise stainless steel.

8. The grill stove of claim 1 , wherein the coal grate comprises at least one handle, a downward-sloping funnel rim, and a grating.

9. The grill stove of claim 1 , wherein the base pan comprises a bottom and sides extending upwardly from the bottom.

10. A grill stove, comprising:
an outer wall including a top portion having a top edge, a bottom portion having a bottom edge, and a plurality of ventilation apertures disposed along the bottom portion, the outer wall having a first height and defining a central axis and being circular in a cross-section perpendicular to the central axis;
an inner wall including a top portion having a top edge and a bottom portion having a bottom edge, the inner wall being coaxial with the outer wall and being devoid of ventilation apertures, the inner wall having a second height less than the first height, the inner wall defining a central chamber;
a bottom attached to the outer wall and forming a bottom of the grill stove;
a nest layer above the bottom and defining an air flow passage in communication with at least one ventilation aperture of the plurality of ventilation apertures;
a fuel grate above the nest layer for supporting a fuel; and
a top collar extending laterally between the inner wall and the outer wall, the top collar connecting the top portion of the outer wall to the top portion of the inner wall, the inner wall and the outer wall being spaced apart to form a gap therebetween, the ventilation apertures being in communication with the gap and in communication with a space below the nest layer, the space below the nest layer in communication with the central chamber.

11. The grill stove of claim 10 , wherein the top collar is a flange extending radially from the inner wall to the top portion of the outer wall.

12. The grill stove of claim 10 , wherein the bottom comprises a plurality of grooves shaped to receive legs of a grill stand.

13. The grill stove of claim 12 , comprising a grill stand having substantially horizontal support arms, the bottom being configured to rest on the support arms.

15. The grill stove of claim 14 , comprising an ash pan having a width wider than a width of the central opening of the funnel.

16. The grill stove of claim 15 , wherein the nest layer comprises a nest pan having an edge and a central ventilation aperture, the edge of the nest pan being attached to the bottom portion of the inner wall and disposed above the bottom, the nest pan and the bottom being spaced apart to form a gap therebetween, the ventilation aperture of the nest pan being in fluid communication with the ventilation aperture of the outer wall.

17. The grill stove of claim 15 , comprising a grill grate disposed above the fuel grate, the grill grate comprising an access door and a handle for opening the access door to provide access to the central chamber.

18. A grill stove, comprising:
an inner wall and a floor portion defining a central chamber;
a removable fuel grate in the central chamber and disposed above the floor portion to support a fuel for heating the grill stove, and
a removable funnel in the central chamber disposed below the fuel grate, the funnel having a central opening for passage of burnt fuel and configured to direct the burnt fuel radially inwardly, the central opening having a first width; and
an ash pan disposed in the central chamber below the funnel, the ash pan having an opening for receiving burnt fuel, the opening having a second width larger than the first width,
wherein the removable funnel is vertically removable through the central chamber.

19. The grill stove of claim 18 , wherein the removable funnel is fixed to the fuel grate and removable from the central chamber with the fuel grate.

20. The grill stove of claim 18 , wherein the fuel grate comprises a handle for grasping by a user and the ash pan comprises a handle for grasping by a user.
