Abstract

A portable Hibachi-type charcoal burning food grill has incorporated therewith a structure for kindling the charcoal and consists of two separate parts: the first part is a shallow upstanding Hibachi-type container for the charcoal, open at the top like a conventional Hibachi and also open at the bottom, the bottom opening being covered by a grate on which the charcoal is piled; and the second part is a tapered upstanding kindling enclosure below the Hibachi that may be integral with or separate from the Hibachi. When provided separately, the kindling enclosure is open at the top, tapers outward from the top to the bottom thereof and has a multitude of uniformly spaced air passage holes therein. The top of the separate kindling structure fits the bottom of the Hibachi so that flames from burning kindling material such as paper, in the kindling enclosure, fed by air flow through the spaced air passages therein flows upward through the opening in the bottom of the Hibachi and ignites the coals on the grate. When the coals are ignited, the Hibachi can be removed from the kindling enclosure and set on its legs if desired.

Claims

1. A portable Hibachi-type charcoal burning food grill in combination with a structure for kindling the charcoal therein comprising,

(a) an upstanding, shallow dish-like casting which is a container for charcoal having outwardly sloping sides from the bottom to the top thereof, at least one large opening through the bottom and legs extending downward from said bottom for supporting said container on a flat surface with the open bottom thereof spaced above the flat surface,

(b) a grate in the container at the bottom thereof covering the bottom opening which together with the sloping sides contains the charcoal,

(c) a kindling structure having closed sides and readily separable from the dish container below the dish container for supporting the container and which defines an enclosure below the container of relatively larger volume than the shallow container for containing burning kindling material,

(d) the top of the kindling structure snugly fitting the bottom of the container around the grate and around the container legs,

(e) the top and bottom of the kindling structure being open so that the structure forms an upstanding combustion chamber and funnel to the grate and

(f) a multitude of air passages through the sides of the kindling structure providing air flow to kindling materials therein,

(g) whereby kindling material placed in the structure and ignited, burns rapidly to ignite charcoal placed in the container on the grate.

2. The combination as in claim 1 wherein,

the air passages are substantially evenly distributed throughout the sides of the kindling structure.

3. The combustion as in claim 2 wherein,

(a) the kindling structure tapers outward from the top to the bottom thereof and

(b) a perimeter surface is provided at the bottom of the charcoal container, encircling the bottom opening thereof outside of the legs, and mates with the top of the kindling structure to funnel gas flow from the structure into a container through the bottom thereof.

4. The combination as in claim 1 wherein,

(a) the kindling structure tapers outward from the top to the bottom thereof.

5. The combination as in claim 1 wherein,

(a) a perimeter surface is provided at the bottom of the charcoal container, encirciling the bottom opening thereof outside of the legs, and mates with the top of the kindling structure when the container rests on the structure to funnel gas flow from the structure into the container at the bottom thereof.

6. The combination as in claim 5 wherein, there are

(a) at least three of said legs attached to the bottom of the charcoal container within said perimeter for supporting the container on a flat surface with the open bottom of the container spaced above the flat surface.

7. The combination as in claim 6 wherein,

(a) the kindling structure tapers outward from the top to the bottom thereof.

8. The combination as in claim 1 wherein the kindling structure is made of sheet metal.
