A cooking apparatus utilizes a bi-level exhaust venting system for an eye level range for conducting heated air from both a front portion and a rear portion of a subjacent stove unit. A first inlet is provided at a top portion of the cabinet, and a second inlet is provided at a bottom portion of the cabinet for conducting air from the front and rear surface units, respectively. A blower draws the conducted air into the upper cabinet and discharges it through a suitable outlet. |

DETAILED DESCRIPTION In accordance with the present invention, a cooking apparatus is provided having an improved bi-level exhaust venting system.
Broadly, there is disclosed herein a ventilation system in a cooking apparatus having a cabinet defining an oven cavity above a subjacent stove portion having front and rear surface heating units.
First inlet means associated with the upper cabinet, opening above the upper cabinet, are provided for conducting air from a forward portion of a space above the stove front surface heating unit.
Similarly, second inlet means are provided associated with the upper cabinet, opening below the upper cabinet, for conducting air upwardly from the space above the rear surface heating units of the stove.
Air flow means in communication with the first and second inlet means discharges air delivered from the inlet means.
The ventilation system comprises a blower disposed within the upper cabinet.
The blower is in communication with an upper vent inlet panel located at a top front portion of the upper cabinet for conducting air upwardly exteriorly of the upper cabinet.
One or more lower inlets are provided in a bottom wall of the upper cabinet for conducting air upwardly from adjacent the surface heating units.
Suitable grease filters may be provided over each of the air inlets.
Air ducts are provided behind opposing side walls of the upper cabinet for communicating air from the lower inlets to the blower.
The blower is also operable to conduct air past electrical control components within the upper cabinet to ventilate and cool same.
A suitable outlet is provided, as required, for exhausting discharge air from the fan.
According to an alternative embodiment, it is an object of the present invention to provide a ventilation system and blower motor control operable to automatically operate the blower at high speed when a preselected high temperature is sensed.
In the alternative embodiment, a thermostat is provided to sense temperature of the upper oven cabinet above the surface heating units
