Abstract
An oven having a central cooking chamber defined in part by a housing and in visual communication with a flame-producing element. The cooking chamber has a door with a transparent portion providing visual inspection of the cooking chamber and a view of the flame produced by the flame producing element. The cooking chamber has a heat source to provide heat to the cooking chamber.
Claims31
A flame oven comprising:
- a) a housing defining a cooking chamber,
- b) a first heating system comprising a base plate heater having a base plate configured to transmit heat therethrough to an upper cooking surface,
- c) a chamber heating element configured to supply heat to the cooking chamber,
- d) a door having a transparent region, the door having a closed and open orientation where in the open orientation, access is provided to the cooking chamber,
- e) a flame chamber positioned transversely behind the cooking chamber relative to the door, the flame chamber defined in part by a backplate at a rearward surface of the flame chamber and a transparent portion at a forward surface of the flame chamber, the transparent portion interposed between and separating the flame chamber and the cooking chamber, the flame chamber having a flame manifold operationally configured to disperse a flame therefrom when in an operational mode,
- f) a control system comprising a first temperature sensor positioned to gauge the temperature of the base plate and a second temperature sensor positioned to read the temperature of the cooking chamber, the control system operatively configured to read the temperature data from the first and second temperature sensors whereby the control circuit alters the heat emission of the base heating element and the chamber heating element to maintain a desired prescribed temperature in the base plate and in the cooking chamber.

An oven comprising:
- a) a central cooking chamber defined in part by a housing, the central cooking chamber having a forward and rearward transverse region and first and second lateral regions, the central cooking chamber defined in part by a lower base plate having an upper surface,
- b) a flame chamber having a flame manifold and a transparent member positioned near the rearward transverse region of the central cooking chamber, the flame chamber having an upper exhaust vent configured to vent combusted gas therethrough,
- c) the transparent member transversely separating the central cooking chamber from the flame chamber,
- d) a chamber heating element positioned in the central cooking chamber,
- e) a baseplate heating element positioned beneath the upper surface of the lower baseplate, and
- f) a door having an interior surface defining a portion of the central cooking chamber, the door further having a surface defining an interior chamber,
- g) the housing further having an upper surface defining an upper convection vent having a first region in communication with the interior chamber of the door and the second region in communication with the upper exhaust vent such that combusted gas passing to the upper exhaust vent of the flame chamber is configured to draw gas through the upper convection vent of the housing and further through the interior chamber of the door.

A method of cooking food comprising the steps of:
- a) providing a cooking chamber with a door for inserting and removing food in and out of the cooking chamber and a flame chamber rearward of the cooking chamber relative to the door of the cooking chamber, a transparent member transversely interposed between and separating the flame chamber and the cooking chamber,
- b) providing a first heating system having a heater positioned below the upper cooking surface of the base plate and providing a chamber heating element positioned in the upper portion of the cooking chamber,
- c) positioning a food item on the upper cooking surface of the base plate and providing heat transfer from the first heating system and the flame chamber assembly where the flame chamber is not in direct airflow communication with the cooking chamber, and
- d) providing a control system controlling the amount of heat transfer to the chamber heating element and the base heating element, and providing a chamber temperature sensor and a base plate temperature sensor which provides a temperature reading to the control system as the control system adjusts the heat transfer to the chamber heating element and the base heating element based upon the temperature readings of the chamber temperature sensor and the base plate temperature sensor.

A flame chambered oven comprising:
- a) a housing having a front region and defining in part a cooking chamber having a forward and rearward transverse region and first and second lateral regions,
- b) a flame chamber rearward of the cooking chamber, the flame chamber having a flame manifold and a transparent member positioned near the rearward transverse region of the cooking chamber separating the cooking chamber from the flame chamber, the flame chamber having an upper exhaust vent configured to vent combusted gas therethrough,
- c) a chamber heating system in thermal communication with the cooking chamber and operatively configured to dispense heat thereto,
- d) a door provided at the forward transverse region of the housing, the door having an interior surface defining a portion of the cooking chamber, the door further having a surface defining an interior chamber, and
- e) the housing further having an upper surface defining an upper convection vent in communication with the interior chamber of the door such that combusted gas passing to the upper exhaust vent of the flame chamber is configured to draw gas through the upper convection vent of the housing and further draw gas through the interior chamber of the door.
