Abstract

A cooking appliance includes an upper cooking surface and a lower cooking surface. The lower cooking surface employs a plurality of horizontally-offset apertures in each of the furrows formed in the lower cooking surface for facilitating the egress of cooking juices from the lower cooking surface.

Claims (21)

1. A smoke reduction system for a cooking appliance having an upper housing having an upper cooking surface and a lower housing having a lower cooking surface, said smoke reduction system comprising:

a plurality of apertures of various sizes formed in a plurality of furrows of said lower cooking surface, said plurality of apertures providing a means of egress for fluids from each of said furrows in said lower cooking surface;

a heating element adjacent said lower cooking surface and in thermal communication therewith; and

a control unit in communication with said heating element, said control unit selectively varying heating parameters of said heating element;

wherein said apertures are elongated slots;

wherein at least one slot of the elongate slots is arranged perpendicular to other slots of the elongated slots; and

wherein a density of said plurality of apertures is greatest adjacent to a middle of said lower cooking surface when viewed from above.

2. A method of reducing smoke and associated odors in a cooking appliance having an upper cooking surface and a lower cooking surface configured to contact a food item from above and below, respectively, said method comprising the steps of:

arranging said upper cooking surface and said lower cooking surface to be in selective opposition to one another;

positioning a heating element adjacent to said lower cooking surface;

forming apertures in a plurality of furrows formed in said lower cooking surface, said apertures providing an egress for fluids from said lower cooking surface;

placing said heating element in communication with a control unit, said control unit selectively varying heating parameters of said heating element; and

wherein said apertures are positioned so as be horizontally offset with respect to said heating element; and

wherein at least some of said plurality of apertures are located near a middle of said lower cooking surface; and

wherein a density of said plurality of apertures is greatest adjacent to said middle of said lower cooking surface when viewed from above to allow for greater draining of fluids at the middle of the lower cooking surface than at locations spaced from the middle.

3. The method of reducing smoke and associated odors in a cooking appliance having an upper cooking surface and a lower cooking surface according to claim 2 , said method further comprising the steps of:

defining said lower cooking surface to have a generally corrugated configuration.

4. The method of reducing smoke and associated odors in a cooking appliance having an upper cooking surface and a lower cooking surface according to claim 2 , said method further comprising the steps of:

defining a plurality of substantially parallel ridges between said furrows of said lower cooking surface.

5. The method of reducing smoke and associated odors in a cooking appliance having an upper cooking surface and a lower cooking surface according to claim 2 , said method further comprising the steps of:

forming said apertures to vary in size in dependence upon their location in said lower cooking surface.
