Abstract

Abstract A portable outdoor barbecue grill having a firebox which communicates simultaneously with a direct cooking chamber and a smoke processing chamber is disclosed. The two chambers are defined by the interior of a drum-like structure. The smoke processing chamber includes a humidifier which may consist of a fluid container with associated piping. The piping channels fluid from the container to the firebox for purposes of heating that fluid. The heated fluid is then returned to the smoke processing chamber and injected into that chamber.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 224 words
An apparatus for cooking and smoke processing foods, said apparatus comprising: a firebox configured to contain a supply of combustibles which produce smoke and heat upon burning for purposes of cooking and smoke processing foods; a first chamber mounted vertically above said firebox and communicating with said firebox, said first chamber configured to receive and retain foods whereby heat and smoke produced within said firebox are directed generally upward into said first chamber for direct cooking of said foods contained therein; a second chamber having means to receive and retain foods, mounted substantially lateral of said firebox and communicating therewith, whereby smoke produced within said firebox is directed into said second chamber for smoke processing said foods contained therein and whereby heat produced within said firebox is generally not directed into said second chamber; and a humidifying means mounted in association with said second cooking chamber for producing moisture within said second cooking chamber during the smoke processing of foods therein; said humidifying means including an open-ended receptacle positioned within said second cooking chamber for containing a supply of liquid and a conduit means associated with said receptacle for receiving a supply of liquid from said receptacle, directing said liquid sufficiently proximate said firebox that heat from said firebox is absorbed by said liquid, and thereafter directing said heated liquid into said second chamber.
Claim 2
Independent Claim 224 words
An apparatus for cooking and smoke processing foods, said apparatus comprising: a firebox configured to contain a supply of combustibles which produce smoke and heat upon burning for purposes of cooking and smoke processing foods; a first chamber mounted vertically above said firebox and communicating with said firebox, said first chamber configured to receive and retain foods whereby heat and smoke produced within said firebox are directed generally upward into said first chamber for direct cooking of said foods contained therein; a second chamber having means to receive and retain foods, mounted substantially lateral of said firebox and communicating therewith, whereby smoke produced within said firebox is directed into said second chamber for smoke processing said foods contained therein and whereby heat produced within said firebox is generally not directed into said second chamber; and a humidifying means mounted in association with said second cooking chamber for producing moisture within said second cooking chamber during the smoke processing of foods therein; said humidifying means including an open-ended receptacle positioned within said second cooking chamber for containing a supply of liquid and a conduit means associated with said receptacle for receiving a supply of liquid from said receptacle, directing said liquid sufficiently proximate said firebox that heat from said firebox is absorbed by said liquid, and thereafter directing said heated liquid into said second chamber.
Claim 3
Dependent Claim 71 words
The cooking apparatus of claim 1 wherein said conduit means comprises a hollow tube having a first and second open end, said first open end being positioned to communicate with said receptacle whereby liquid contained in said receptacle may be channeled into said hollow tube, said second end being positioned within said second cooking chamber whereby heated liquid exiting through said second open end is discharged into said second cooking chamber.
Claim 4
Dependent Claim 19 words
The cooking apparatus of claim 2 wherein said tube is sealed except for said first and second open end.
Claim 5
Dependent Claim 16 words
The cooking apparatus of claim 2 wherein said second open end is positioned within said receptacle.
Claim 6
Dependent Claim 16 words
The cooking apparatus according to claim 1 wherein said second chamber includes at least one vent.
Claim 7
Dependent Claim 25 words
The cooking apparatus according to claim 5 wherein said vent is fitted with a removal means for forcibly removing air from within said second chamber.
Claim 8
Dependent Claim 39 words
The cooking apparatus according to claim 1 further having a heating drawer positioned within said second chamber, said heating drawer being adapted to receive foods and retain those foods free from contact with said smoke within said second chamber.
Claim 9
Independent Claim 162 words
An apparatus for cooking and smoke processing foods, said apparatus comprising: a firebox configured to contain a supply of combustibles, which produce heat and smoke upon burning, for purposes of cooking and smoke processing foods; a smoke chamber, having means to receive and retain foods, mounted in association with said firebox and communicating therewith, whereby smoke produced within said firebox is directed into said smoke chamber for smoke processing said foods contained therein; and a humidifying means mounted in association with said smoke chamber for producing moisture within said smoke chamber during the smoke processing of said foods therein; said humidifying means including an open-ended receptacle positioned within said second cooking chamber for containing a supply of liquid and a conduit means associated with said receptacle for receiving a quantity of liquid from said receptacle, directing said liquid sufficiently proximate said firebox that heat from said firebox is absorbed by said liquid, and thereafter directing said heated liquid into said second chamber.
Claim 10
Independent Claim 162 words
An apparatus for cooking and smoke processing foods, said apparatus comprising: a firebox configured to contain a supply of combustibles, which produce heat and smoke upon burning, for purposes of cooking and smoke processing foods; a smoke chamber, having means to receive and retain foods, mounted in association with said firebox and communicating therewith, whereby smoke produced within said firebox is directed into said smoke chamber for smoke processing said foods contained therein; and a humidifying means mounted in association with said smoke chamber for producing moisture within said smoke chamber during the smoke processing of said foods therein; said humidifying means including an open-ended receptacle positioned within said second cooking chamber for containing a supply of liquid and a conduit means associated with said receptacle for receiving a quantity of liquid from said receptacle, directing said liquid sufficiently proximate said firebox that heat from said firebox is absorbed by said liquid, and thereafter directing said heated liquid into said second chamber.
Claim 11
Dependent Claim 71 words
The cooking apparatus fo claim 8 wherein said conduit means comprises a hollow tube having a first and second open end, said first open end being positioned to communicate with said receptacle whereby liquid contained in said receptacle may be channeled into said hollow tube, said second end being positioned within said second cooking chamber whereby heated liquid exiting through said second open end is discharged into said second cooking chamber.
Claim 12
Dependent Claim 19 words
