Combustion cooking appliance

Abstract

A cooking appliance has a cooking zone comprising a cooking surface, a combustion zone that is in thermal communication with the cooking zone, wherein the cooking zone is isolated from combustion products produced by combustion in the combustion zone, and a drip tray that is positioned external to the cooking zone and the cooking surface directs liquid produced during cooking to the drip tray.

         7 . The cooking appliance of clause 6 wherein the cooking surface has a plurality of drainage channels that are in flow communication with the drip tray. 
     
     
         8 . The cooking appliance of clause 7 wherein the cooking surface further comprises a plurality of peaks and a lower surface of the peaks comprises part of an outer wall of the combustion zone whereby the lower surface of the peaks is exposed to combustion products when combustion occurs in the combustion zone. 
     
     
         9 . The cooking appliance of clause 7 wherein a body forming the cooking surface is transparent to IR radiation. 
     
     
         10 . The cooking appliance of clause 1 wherein a body forming the cooking surface is transparent to IR radiation and an openable lid is IR reflective. 
     
     
         11 . The cooking appliance of clause 1 wherein the cooking zone is isolated from combustion products. 
     
     
         12 . The cooking appliance of clause 7 wherein the cooking appliance has a front and a rear, an openable lid has a rear end that is moveably mounted with respect to the cooking appliance, and the drainage channels extend in a forward/rearward direction. 
     
     
         13 . The cooking appliance of clause 12 wherein the cooking surface further comprises a plurality of peaks, and the peaks have a thickness that is less than a thickness of a lower surface of the drainage channels. 
     
     
         14 . The cooking appliance of clause 13 wherein a body forming the cooking surface is transparent to IR radiation. 
     
     
         15 . The cooking appliance of clause 13 wherein a body forming the cooking surface is transparent to IR radiation and an openable lid is IR reflective. 
     
     
         16 . The cooking appliance of clause 1 wherein the cooking surface is made of copper and/or aluminum. 
     
     
         17 . The cooking appliance of clause 1 wherein the cooking surface has a region for receiving a combustible material, the cooking surface further comprises a plurality of peaks, and the region has a lower end which is below the peaks. 
     
     
         18 . The cooking appliance of clause 1 wherein the cooking appliance has a front and a rear, an openable lid has a rear end that is moveably mounted with respect to the cooking appliance, and the drip tray is provided at the front of the cooking appliance. 
     
     
         19 . The cooking appliance of clause 1 wherein the drip tray is removable from the cooking appliance and provided on an exterior surface of the cooking appliance. 
     
     
         20 . The cooking appliance of clause 1 wherein the cooking appliance has a lower end that is insulated to seat on a counter surface, the cooking surface has a plurality of drainage channels that are in flow communication with the drip tray and the drip tray is positionable on the counter surface and underneath an outlet end of the drainage channels without being mounted to the cooking appliance.
