Outdoor pizza oven

1. An oven comprising:

an upper portion;

a lower portion configured to interface with the upper portion to define an enclosed volume, wherein the lower portion is further configured to receive a heat source to provide heat to the enclosed volume, wherein the enclosed volume comprises:

a lower region defined by the lower portion, and

an upper region defined by the upper portion;

a cooking surface apparatus suspended within the enclosed volume and defining a cooking surface facing the upper region of the enclosed volume configured to receive cookable material thereon, wherein the cooking surface apparatus comprises a baking stone defining the cooking surface, wherein the baking stone is configured to provide the cooking surface of the cooking surface apparatus; and

fire bowl apparatus located in the lower region of the enclosed volume and configured to hold combustible material away from an inner wall of the lower portion to allow airflow around and through the fire bowl apparatus, wherein the fire bowl apparatus defines an inverted stepped conical region configured to hold combustible material,

wherein the upper portion defines an upper passage from outside of the oven into the upper region of the enclosed volume and comprises upper door apparatus configurable in at least an open position and a closed position, wherein, when in the open position, the upper door apparatus allows passage of material through the upper passage into the upper region of the enclosed volume from outside of the oven and, when in the closed position, the upper door apparatus prevents passage of material through the upper passage into the upper region of the enclosed volume,

wherein the lower portion defines a lower passage from outside of the oven into the lower region of the enclosed volume and comprises lower door apparatus configurable in at least an open position and a closed position, wherein, when in the open position, the lower door apparatus allows passage of material through the lower passage into the lower region of the enclosed volume from outside of the oven and, when in the closed position, the lower door apparatus prevents passage of material through the lower passage into the lower region of the enclosed volume.

2. The oven of claim 1 , wherein the fire bowl apparatus further comprises a plurality of radially-extending arm members that define a plurality apertures configured to allow airflow therethrough.

3. The oven of claim 1 , wherein each of the upper portion and the lower portion defines one or more vent openings extending from the enclosed volume to outside of the oven, wherein the oven further comprises an upper vent apparatus coupled to the upper portion proximate to the one or more vent openings and a lower vent apparatus coupled to the lower portion proximate to the one or more vent openings, wherein each of the upper vent apparatus and the lower vent apparatus is configurable between an open position and a closed position, wherein, when in the open position, the vent apparatus allows passage of air between the enclosed volume and outside of the oven through the one or more vent openings and, when in the closed position, the vent apparatus restricts passage of air between the enclosed volume and outside of the oven through the one or more vent openings.

4. The oven of claim 1 , wherein the lower portion defines one or more vent openings extending from the enclosed volume to outside of the oven, wherein the oven further comprises lower vent apparatus coupled to the lower portion proximate to the one or more vent openings and configured to selectively provide passage of air between the enclosed volume and outside of the oven through the one or more vent openings, wherein the one or more vent openings are configured to allow air to flow underneath combustible material located in the fire bowl apparatus from outside of the oven and to allow combusted material to pass from the fire bowl apparatus to outside of the oven.

5. The oven of claim 1 , wherein the oven further comprises heat control apparatus defining a circular region and a ring region located outside of the circular region, wherein the ring region defines a plurality of apertures to allow passage of air in the enclosed volume between the lower region and the upper region.
