An improved food oven apparatus and related methods for preparing food utilizing digitally controlled heating elements and a smoker unit. User-operable controls in communication with a digital controller allow for independent control of the heating elements and the smoker unit. One or more electric fans can be provided for reducing condensation from forming within a control unit of the food oven. A heating element connection assembly can also be provided for reducing stress exerted on the heating elements caused by the repeated expansion and contraction of the compartment. The food oven can also be provided with an air cleaning apparatus configured to perform a multi-stage cleaning process, thereby eliminating the need for a separate fixed hood system.
1. A food oven apparatus comprising:
a housing having a first oven compartment therein;
a first support member positionable within the first compartment for holding food to be prepared within the first compartment;

a first heating element disposed within the first compartment for heating the first compartment, the first heating element is positioned on a first side of the first support member;
a second heating element disposed within the first compartment for heating the first compartment, the second heating element is positioned on a second side of the support member;
the heating elements configured to adjust and allow relative movement between the heating elements and the first compartment to accomodate thermal expansion and contraction of the first compartment;
a first smoker unit disposed within the first compartment for generating smoke within the first compartment;
a first digital controller in communication with the first and second heating elements and the first smoker unit; and
a first set of user-operable controls in communication with the first digital controller for independently controlling each of the first and second heating elements and the first smoker unit in response to user operation of the first set of controls.
2. The food oven apparatus of claim 1 , further comprising:
a control unit positioned on a top surface of the housing, the digital controller is disposed within the control unit, the user-operable controls are accessible from a front panel of the control unit.
3. The food oven apparatus of claim 2 , further comprising:
a vent positioned on an exterior surface of the control unit;
an electric fan disposed within the control unit for passing air out of the control unit through the vent.
4. The food oven apparatus of claim 1 , the first digital controller providing functionality for recording a cooking cycle.
5. The food oven apparatus of claim 1 , the first digital controller is compatible with a NAFEM protocol.
6. The food oven apparatus of claim 1 , further comprising:
a probe in communication with the first digital controller for monitoring cooking temperatures of the food to be prepared within the first compartment.
7. The food oven apparatus of claim 1 , the housing is formed of a stainless steel material.
8. The food oven apparatus of claim 1 , the housing is a double wall housing, the apparatus further comprising:
an aperture in an interior wall of the housing, at least one of the heating elements passing through the aperture;
a spacer engaging the at least one of the heating elements and the interior wall of the housing;
a washer engaging the at least one of the heating elements and an exterior wall of the housing; and
a spring engaging the spacer and washer, the spring is configured to compress and decompress in response to expansion and contraction of the first compartment.
9. The food oven apparatus of claim 1 , further comprising:
a cavity defined by the top surface of the housing and the vent shroud;
an exhaust vent in the top surface of the housing;
a convection aperture in the first compartment for receiving exhaust air from the first compartment;
a chimney disposed between the convection aperture and the exhaust vent, the chimney configured to receive the exhaust air from the convection aperture and pass the exhaust air to the exhaust vent;
an air cleaning apparatus disposed within the cavity, the air cleaning apparatus comprising:
a mesh filter for receiving the exhaust air from the exhaust vent,
an electrostatic precipitator for receiving the exhaust air from the mesh filter, and
a charcoal filter for receiving the exhaust air from the electrostatic precipitator; and
an exhaust aperture in a top surface of the vent shroud for receiving the exhaust air from the charcoal filter and passing the exhaust air to an exterior of the food oven apparatus.
10. The food oven apparatus of claim 1 , further comprising:
a second oven compartment within the housing;
a second support member positionable within the second compartment for holding food to be prepared within the second compartment;
a third heating element disposed within the second compartment for heating the second compartment, the third heating element is positioned on a first side of the second support member;
a fourth heating element disposed within the second compartment for heating the second compartment, the fourth heating element is positioned on a second side of the second support member;
a smoker unit disposed within the second compartment for generating smoke within the second compartment;
a second digital controller in communication with the third and fourth heating elements and the second smoker unit; and
a second set of user-operable controls in communication with the second digital controller for independently controlling each of the third and fourth heating elements and the second smoker unit in response to user operation of the second set of controls.
