Abstract
A system for reducing discharges from an oven prior to opening an oven door. In particular, the system includes a housing forming a cooking compartment arranged within the oven. The system also includes a purge passage extending through the housing into the cooking compartment and a cover arranged over a portion of the purge passage to removeably block the purge passage. An expelling port is included that extends from the cooking compartment through the housing. A controller is configured to remove the cover from blocking the purge passage to inject air into the cooking compartment through the purge passage and displace substances within the cooking compartment through the expelling port.
