The invention relates generally to apparatus for cooking foods with heat and more particularly to a barbeque grill that employs infrared heat to cook selected food items.
Cooking apparatus such as barbeque grills are known to the art. In most embodiments, the barbeque grill includes a body or housing for enclosing a heat source, such as gas burners or charcoal, and a grill positioned above the heat source. The food products, such as meat, vegetables, sea food or the like, are placed on the grill for cooking. The grill typically is a grid or lattice work structure that allows heat from the heat source to reach the food. Also, the grill allows juices, grease or fat to drip on the heat source.
In gas barbeque grills, gas burners are the heat sources that produce a flame. In charcoal barbeque grills, burning charcoal produces radiant heat and sometimes flame. In the former, the heat level is controlled by controlling gas flow to the burner. The level of heat is more difficult to control in charcoal barbeque grills. In either apparatus, it is difficult to prevent flames from scorching or burning the food, for example if grease or basting oils drip on the heat source and flames up.
Cooking apparatus that have a barrier between the food and a gas heat source are known. However, it would be advantageous to provide a cooking apparatus that accommodates charcoal as the heat source and includes an infrared energy emitter positioned between the charcoal and the food on the grill.
Briefly stated, cooking apparatus comprising a housing that defines an inner cooking chamber, a charcoal tray in the burn chamber and a cooking surface above the charcoal tray. An infrared energy emitter is positioned between the charcoal tray and the cooking surface.
In one aspect, the cooking surface is a cooking grid or grill.
In one aspect, the infrared energy emitter is a radiant element such as a ceramic, glass or metal element positioned above the burn chamber and just below the cooking grids. The radiant element absorbs heat energy which is generated by the charcoal fuel source in the charcoal tray in the form of convection, and infrared radiant heat from the burning coals that is heated and transfers the heat and radiant energy to the food. The radiant element reaches temps of about 200° to about 1000° F. depending on air flow into the burn chamber which can be controlled by air flow adjustments.
In one illustrated embodiment, the radiant element is a radiant glass or ceramic element.
The housing includes a lid and is sealed; air controls allow for the total control of cooking temperatures between about 200° and about 800° F. with the lid closed.
In another aspect, the radiant element acts as a diffuser between the charcoal and food.
In another aspect, the radiant element provides a hot surface for juices and drippings to fall on and vaporize back up through to the food to give the food moisture and flavor.
Infrared radiant cooking cooks from the outside inward which sears the food surface first locking in the juices and then continuing to cook through to the center.
In another aspect, the radiant element is removable for cleaning and for use of the cooking apparatus as a conventional charcoal grill.
In one aspect the radiant element is a radiant glass or ceramic element is thermo shock resistant and will not crack as a result of water or liquids contacting the hot surface.
The infrared charcoal grill of the present invention is indicated by reference number 10 in
There is a pedestal 16 on the base and the main grill body 18 at the top of the pedestal. Although this arrangement of grill body, pedestal and base is one preferred embodiment of grill 10, it is intended to be illustrative. Grill 10 can have any overall configuration and components. For example it could have multiple legs and no pedestal or base; it could have short legs for a table top version. The number of elements or arrangement is limitless.
In any event, as show, body 18 comprises a box-like housing having a bottom section 20 and a lid 22. The bottom section and lid each define inner chambers which together define a firebox/cooking chamber 23. In one embodiment the body is constructed from heavy cast aluminum. Lid 22 includes a top vent 24 for controlling airflow and heat, a thermometer 26 that is in functional communication with the interior of body, and a handle 28. Again the configuration and arrangement of these elements can vary. It will be noted that lid 22 can be attached to the bottom section by a hinge engages the perimeter of bottom section 20 in an airtight fit provided by seals.
Bottom section 20 defines an opening 29 (

Radiant element 52 is positioned above the fuel and is just below cooking grids 54. Element 52 absorbs the heat energy which is generated by the charcoal fuel source in the form of convection, and infrared radiant heat from the burning coals which will heat radiant element 52 and transfer the heat and radiant energy to the food.
Element 52 optimally reaches temps of about 200° F. to about 1000° F. depending on the controlled air flow adjustments of vents 24, 42 and 44. Element 52 also acts as a diffuser between the charcoal and food which also provides a hot surface for juices and drippings to fall on and vaporize back up through to the food giving the food moisture and flavor which generally does not happen with direct charcoal grilling.
Element 52 is easily removed for cleaning and conventional charcoal grilling. Element 52 can be provided with the grill, or can be provided as an accessory to the grill. Ceramic or glass elements are thermo shock resistant and will not crack do to water or liquids contacting the hot surface. The sealed grill housing and air controls allow for the total control of oven temps between 200° F. and 800° F. with lid 22 closed. Infrared radiant cooking will cook foods from the outside inward which sears the food surface first locking in the juices and then continuing to cook through to the center.
