Abstract

A lower housing has a fuel grate situated at a predetermined level within the lower housing for supporting a fuel source. The lower housing has a first wall defining a plurality of air intake openings proximate the level of the fuel grate.

First claim

What is claimed is:

1. A grill comprising:
a lower housing having a top opening;
a cover fitting the top opening and having an exhaust opening therein;
a fuel grate situated at a first predetermined elevation within the lower housing for supporting a fuel source;
a cooking grate situated at a second predetermined elevation within the lower housing above the elevation of the fuel grate; and
a baffle ring spaced apart from the fuel grate and extending over at least a portion of the fuel grate;
wherein the lower housing has a first wall defining a plurality of air intake openings above the elevation of the fuel grate and defines no air intakes below the elevation of the fuel grate; and
wherein the baffle ring is spaced apart from the plurality of air intake openings and on a common plane with the plurality of air intake openings.

2. The grill of claim 1 , wherein the lower housing has a double walled construction with a second, inner wall providing a plurality of air intake openings.

3. The grill of claim 2 , wherein the openings of the inner wall are vertically proximate the openings of the first wall.

4. The grill of claim 2 , wherein the openings of the inner wall are substantially vertically offset from the openings of the first wall.

5. The grill of claim 1 , further comprising:
a second wall, interior to the first wall, having at least one opening below the fuel grate and defining a first air passageway between the first and second wall; and
a third wall, interior to the second wall, having a termination proximate the fuel grate, and defining a second air passageway between the second and third wall;
wherein air communicates between the first and second air passageways via the at least one opening of the second wall; and wherein air is communicated to the fuel grate at the termination of the third wall.

6. A grill comprising:
a single-walled lower kettle housing having a cooking grate supported above and spaced apart from a fuel grate in an interior of the housing;
a cover at least partially covering the cooking grate and defining an exhaust opening; and
a baffle ring superior to the fuel grate and circumscribing over at least part of the fuel grate;
wherein the lower housing defines a plurality of air intake openings encircling the lower housing above a level of the fuel grate;
wherein the plurality of air intake openings define a horizontal air pathway to the interior of the housing; and
wherein the baffle ring is vertically oriented to arrest embers flowing from the fuel grate to an outside of the housing through at least one of the plurality of air intake openings.

7. A method comprising:
forming a housing with a heating chamber defined within an upright wall, a top opening, and a removable cover over the top with an exhaust opening;
providing a fuel grate in the housing;
providing a cooking grate above the fuel grate;
creating a plurality of air openings in the upright wall above a vertical level of the fuel grate laterally surrounding the heating chamber, with no other air openings into the upright wall of housing, the plurality of air openings providing horizontal air pathways between the heating chamber and exterior of the housing; and
placing an upright baffle ring in the heating chamber offset from the air openings and the fuel grate and circumscribing the fuel grate over the top thereof such that solids from fuel combusting on the fuel grate are impeded from escaping the heating chamber by via the horizontal air pathways.
