Claim 8

The claimed subject matter of claim 6 further defined as including heat-insulating means between the heat source and said additional wall means to thereby reduce heat transmitted thereto.

Claim 9

A cooking device comprising: A frame including wall means defining an upwardly facing recess, a heat cartridge defined by a flat heat-transmissive ceramic panel in cooperation with walls generally spaced therefrom to define a chamber therebetween and including a heat source in the chamber for heating the ceramic panel, said heat cartridge disposed in said recess with the ceramic panel facing upwardly therefrom to define a surface for cooking, said walls of the heat cartridge being spaced from the frame wall means to define a space therebetween, and means for moving outside air through said space and adjacent the walls of said cartridge for removing heat therefrom to thereby reduce heat transfer To the frame.

Claim 10

A cooking device comprising: A frame including wall means defining an upwardly facing recess, a heat cartridge defined by a flat heat-transmissive ceramic panel in cooperation with walls generally spaced therefrom to define a chamber therebetween and including a heat source in the chamber for heating the ceramic panel, said heat cartridge disposed in said recess with the ceramic panel facing upwardly therefrom to define a surface for cooking, said walls of the heat cartridge being spaced from the frame wall means to define a space therebetween, and means for moving outside air through said space and adjacent the walls of said cartridge for removing heat therefrom to thereby reduce heat transfer To the frame.

Claim 11

The claimed subject matter of claim 8 further defined as including heat-insulating means beneath the heat source to reduce heat transfer to surfaces other than said panel.

Claim 12

The claimed subject matter of claim 8 wherein the chamber of said heat cartridge is entirely enclosed.

Claim 13

The claimed subject matter of claim 8 wherein said heat cartridge is removably received in the stove recess.

Claim 14

The claimed subject matter of claim 8 wherein said heat cartridge closes the entrance to said recess of the frame.

Claim 15

A cooking device comprising: a frame including wall means defining an upwardly facing recess, a heat cartridge including a flat heat-transmissive ceramic panel across the opening to a pan means to define a chamber and having a heat source therein, said heat cartridge disposed within said recess with said ceramic panel facing upwardly therefrom for defining a cooling surface, said heat source within the chamber of said heat cartridge being so disposed that a major portion of its heat is transmitted to said ceramic panel and only a minor portion is transmitted to the pan means, and means for moving a continuous stream of cooling air past and in contact with the pan means for removing heat therefrom to thereby reduce heat transmission to the frame.

Claim 16

A cooking device comprising: a frame including wall means defining an upwardly facing recess, a heat cartridge including a flat heat-transmissive ceramic panel across the opening to a pan means to define a chamber and having a heat source therein, said heat cartridge disposed within said recess with said ceramic panel facing upwardly therefrom for defining a cooling surface, said heat source within the chamber of said heat cartridge being so disposed that a major portion of its heat is transmitted to said ceramic panel and only a minor portion is transmitted to the pan means, and means for moving a continuous stream of cooling air past and in contact with the pan means for removing heat therefrom to thereby reduce heat transmission to the frame.

Claim 17

The claimed subject of claim 13 wherein said heat source is disposed adjacent said panel.

Claim 18

The claimed subject matter of claim 13 wherein the chamber of said heat cartridge is entirely enclosed.

Claim 19

The claimed subject matter of claim 13 wherein said heat cartridge is removably received in the stove recess.

Claim 20

The claimed subject matter of claim 13 wherein the entrance to said recess in the frame is closed by said cartridge.

Claim 21

A cooking device comprising: a frame including wall means defining an upwardly facing cavity, a generally flat heat-transmissive glass ceramic panel disposed across the entrance to said cavity with a heat source underneath whereby said panel becomes a surface for cooling, additional wall means disposed in said cavity and beneath said panel and heat source thereby defining a heat chamber, said additional wall means being spaced upwardly from a bottom wall of said frame cavity to define conduit means therebetween for passage of a stream of cooling air, an air opening in the frame in communication with said conduit means, an air plenum chamber adjacent said frame and having plural air intake ports and an exhaust port in communication with a power driven fan exhaust adapted to exhaust air to the atmosphere, one of said intake ports adjacently disposed to one side of said panel for drawing cooking fumes from thereacross and another intake port in communication with said conduit means for drawing cooling air therethrough in contact with said additional wall means for removing heat therefrom to reduce heat transfer to said frame.

Claim 22

A cooking device comprising: a frame including wall means defining an upwardly facing cavity, a generally flat heat-transmissive glass ceramic panel disposed across the entrance to said cavity with a heat source underneath whereby said panel becomes a surface for cooling, additional wall means disposed in said cavity and beneath said panel and heat source thereby defining a heat chamber, said additional wall means being spaced upwardly from a bottom wall of said frame cavity to define conduit means therebetween for passage of a stream of cooling air, an air opening in the frame in communication with said conduit means, an air plenum chamber adjacent said frame and having plural air intake ports and an exhaust port in communication with a power driven fan exhaust adapted to exhaust air to the atmosphere, one of said intake ports adjacently disposed to one side of said panel for drawing cooking fumes from thereacross and another intake port in communication with said conduit means for drawing cooling air therethrough in contact with said additional wall means for removing heat therefrom to reduce heat transfer to said frame.
