Abstract

A cooking appliance includes an upper housing having a first heating surface and a lower housing operatively connected to the upper housing. The lower housing has a second heating surface having a plurality of apertures therethrough for facilitating the egress of cooking juices from the second heating surface.

First claim

What is claimed is:

1. A cooking appliance, comprising:
an upper housing having a first heating surface;
a lower housing operatively connected to said upper housing, said lower housing having a second heating surface with a plurality of furrows;
opposed frame members disposed between said upper housing and said lower housing and operatively receiving said upper housing via a guiding track;
wherein said plurality of furrows of said second heating surface has a plurality of apertures of various sizes there through for facilitating the egress of cooking juices from said second heating surface;
wherein said apertures are positioned to be horizontally offset from a heating element positioned below said second heating surface, and
a control unit in communication with said first heating surface and said second heating surface;
wherein said control unit selectively varying heating parameters of said first heating surface and said second heating surface;
wherein said first heating surface is substantially parallel to said second heating surface.

2. The cooking appliance of claim 1 , wherein:
said second heating surface has a generally corrugated configuration.

3. The cooking appliance of claim 2 , wherein:
said second heating surface has a plurality of substantially parallel ridges between said furrows.

4. The cooking appliance of claim 1 , wherein:
said apertures are elongated slots.

5. The cooking appliance of claim 1 , wherein:
said second heating surface has upstanding lateral sidewalls.

6. The cooking appliance of claim 1 , further comprising:
a collecting tray slidably received in said lower housing and positionable beneath said second heating surface.

7. A smoke reduction system for a cooking appliance having an upper housing having an upper heating surface and a lower housing having a lower heating surface, said smoke reduction system comprising:
a plurality of apertures of various sizes formed in a plurality of furrows of said lower heating surface, said plurality of apertures providing a means of egress for fluids from said lower heating surface; and
a control unit in communication with said upper heating surface and said lower heating surface, said control unit selectively varying heating parameters of said upper heating plate and said lower heating plate,
wherein said apertures are positioned horizontally offset a heating element positioned below said lower heating surface;
wherein said upper heating surface is substantially parallel to said lower heating surface.

8. The smoke reduction system for a cooking appliance of claim 7 , further comprising:
a collecting tray slidably received in said lower housing and positionable beneath said lower heating surface.

9. The smoke reduction system for a cooking appliance of claim 7 , wherein:
said heating surface has a generally corrugated configuration.

10. The smoke reduction system for a cooking appliance of claim 9 , wherein:
said heating surface has a plurality of substantially parallel ridges and furrows.

11. The smoke reduction system for a cooking appliance of claim 10 , wherein:
said apertures are formed in said heating surface in an area of said furrows.

12. The smoke reduction system for a cooking appliance of claim 7 , wherein:
said apertures are elongated slots.

13. A cooking appliance, comprising:
an upper housing having a first heating surface;
a lower housing operatively connected to said upper housing and having a second heating surface, said first heating surface and said second heating surface being selectively heated to a predetermined temperature;
wherein second heating surface has a plurality of apertures of differing sizes formed in each of a plurality of furrows therethrough for facilitating the egress of cooking juices from said second heating surface; and
wherein said apertures are positioned to be horizontally offset from a heating element positioned below said second heating surface, so as to prevent the cooking juices from contacting said heating element;
wherein said first heating surface is substantially parallel to said second heating surface.
