Abstract

A floor and an upright sidewall formed from two vertically coaxial components, each component having a floor baffle with a plurality of floor openings defined therein, each floor retained within a respective upright sidewall with a plurality of sidewall openings defined therein. The floor openings and the sidewall openings cooperate between the two coaxial components such that flow of gases through the floor and upright sidewall of the baffle structure is controlled by rotation of the two vertically coaxial components relative to one another.

First claim

What is claimed is:

1. A cooking appliance comprising,
a cooking grate supported over a fire box having a firepot contained therein that burns solid pelletized fuel fed from an auger running from outside the firebox; and
a baffle structure arranged above the firepot and having an upper component nested coaxially within lower component with the upper and lower components rotatable with respect to one another;
wherein the upper component has a floor defining a first plurality of floor openings therein, the first plurality of openings being arranged in first predetermined pattern on the floor of the upper component;
wherein the lower component has a floor defining a second plurality of floor openings therein, the second plurality of openings being arranged in second predetermined pattern on the floor of the lower component; and
wherein the upper component floor rests in contact with the lower component floor and the first and second predetermined patterns of the respective floor openings defined in the respective floors are arranged such that overlap of the first and second plurality of openings may be selected, deselected, or partially selected by rotation of the upper component relative to the lower component;
wherein the upper and lower components further comprise upper and lower upright sidewalls, respectively, joining the respective floors;
wherein the upper and lower upright sidewalls define a plurality of upper sidewall openings and a plurality of lower sidewall openings respectively;
wherein the upper upright sidewall openings and the lower upright sidewall openings have a configuration such that overlap between the first plurality of upright sidewall openings and the second plurality of upright sidewall openings may be selected, deselected, or partially selected by rotation of the upper component relative to the lower component;
wherein the overlap between the first and second plurality of floor openings is partially selected when the overlap in the between the first and second plurality of upright sidewall openings is not selected; and
wherein the overlap between the first and second plurality of floor openings is not selected when the overlap in the between the first and second plurality of upright sidewall openings is partially selected.

2. The cooking appliance of claim 1 , wherein the upper component further comprises a removable mid baffle spaced apart from the upper component floor.

3. The cooking appliance of claim 2 , further comprising support structure supporting the baffle structure over the firepot.

4. The cooking appliance of claim 2 , wherein the baffle structure interposes the firepot and the cooking grate and defines a high temperature zone on the cooking grate that is active when the overlap between the first and second plurality of floor openings is selected.
