Abstract
An outdoor oven may have a cooking chamber defined by six sides. Each of the six sides may be insulated. A front side may have a door for access to the cooking chamber. The cooking chamber may have a baffle and a cooking plane above and separated some distance from the baffle. Heat in the form of a flame may enter the cooking chamber. The baffle may prevent heat from the flame from directly contacting food on the cooking plane, may inhibit heat transfer through the baffle, and/or may direct heated air around the baffle. The heat is circulated through the cooking chamber to heat the food, and exits a vent positioned below the cooking chamber. An outdoor cooking system may include a burner, a support structure and a fuel supply.
Claims20
An outdoor oven, comprising:
- a combustion burner;
- a top, a bottom, and four sides forming a cooking chamber, wherein the bottom comprises an opening for receiving combustion air flow from the combustion burner, wherein the combustion burner is positioned outside the cooking chamber below the opening, wherein one side of the four sides comprises a door;
- a substantially planar baffle comprising a thickness and material selected to inhibit heat transfer through the baffle, wherein a planar dimension of the baffle is larger than a planar dimension of the opening and less than an interior dimension of the cooking chamber to permit combustion air flow to pass around the baffle and inside the cooking chamber, wherein the baffle is located inside the cooking chamber at a first distance above the opening;
- a cooking plane member positioned a distance below the cooking chamber top side and above the planar baffle and defining an upper portion and lower portion of the cooking chamber, configured for supporting items located within an upper portion of the cooking chamber, and configured to permit heated air and combustion products to pass into said upper portion of the cooking chamber above the cooking plane member and into a lower portion of the cooking chamber below the cooking plane member, wherein the lower portion of the cooking chamber is above the baffle;
- and
- a vent passing through the side opposite the door, whereby the cooking chamber is in communication with the environment, wherein the vent comprises a slot having a length substantially equal to a length of the cooking plane member and is located above the opening and below the baffle, wherein air exits the cooking chamber substantially through the vent.

An outdoor cooking system, comprising:
- a combustion burner;
- a top, a bottom, and four sides forming a cooking chamber, wherein the bottom comprises an opening for receiving combustion air flow from the combustion burner, wherein the combustion burner is positioned outside the cooking chamber below the opening, wherein one side of the four sides comprises a door;
- a substantially planar baffle comprising a thickness and material selected to inhibit heat transfer through the baffle, wherein a planar dimension of the baffle is larger than a planar dimension of the opening and less than an interior dimension of the cooking chamber to permit combustion air flow to pass around the baffle and inside the cooking chamber, wherein the baffle is located inside the cooking chamber at a first distance above the opening;
- a cooking plane member positioned a distance below the cooking chamber top side and above the planar baffle and defining an upper portion and lower portion of the cooking chamber, configured for supporting items located within an upper portion of the cooking chamber, and configured to permit heated air and combustion circulates in the upper portion of the cooking chamber above the cooking plane member and in the lower portion of the cooking chamber below the cooking plane member;
- a vent passing through the side opposite the door, whereby the cooking chamber is in communication with the environment, wherein the vent comprises a slot having a length substantially equal to a length of the cooking plane member and is located above the opening and below the baffle, wherein air exits the cooking chamber substantially through the vent;
- a fuel source for supplying fuel to the combustion burner;
- and
- a base for supporting the cooking chamber, comprising:
- a top surface having an opening corresponding to the opening in the bottom of the cooking chamber;
- and
- a burner control valve for controlling the fuel flow from the fuel source to the combustion burner, wherein the size and position of one or more of the combustion burner, the baffle and the vent cooperate to circulate heat through the cooking chamber.

A portable outdoor cooking apparatus, comprising:
- a combustion burner;
- a top, a bottom, and four sides forming a cooking chamber,
- wherein the bottom comprises an opening for receiving combustion air flow from the combustion burner, wherein the combustion burner is positioned outside the cooking chamber below the opening, wherein one side of the four sides comprises a door;
- a substantially planar baffle comprising a thickness and material selected to inhibit heat transfer through the baffle, wherein a planar dimension of the baffle is larger than a planar dimension of the opening and less than an interior dimension of the cooking chamber to permit combustion air flow to circulate around the baffle and inside the cooking chamber, wherein the baffle is located inside the cooking chamber at a first distance above the opening;
- a cooking plane member positioned a distance below the cooking chamber top side and above the planar baffle and defining an upper portion and lower portion of the cooking chamber, configured for supporting items located within an upper portion of the cooking chamber, and configured to permit heated air and combustion circulates in the upper portion of the cooking chamber above the cooking plane member and in the lower portion of the cooking chamber below the cooking plane member;
- a vent passing through the side opposite the door, whereby the cooking chamber is in communication with the environment, wherein the vent comprises a slot having a length substantially equal to a length of the cooking plane member and is located above the opening and below the baffle, wherein air exits the cooking chamber substantially through the vent;
- a fuel source for supplying fuel to the combustion burner;
- and
- a base for supporting the cooking chamber, comprising:
- a top side having an opening corresponding to the opening in the bottom side of the cooking chamber;
- a burner control valve for controlling the fuel flow from the fuel source to the combustion burner;
- and
- four sides extending down from the top side, wherein the size and position of one or more of the burner, the baffle and the vent cooperate to circulate combustion air flow through the cooking chamber.
