a cabinet comprising a plurality of outer panels and defining an airflow path extending through the cabinet, the plurality of outer panels comprising a bottom panel defining a high-flow center segment and an outer low-flow segment;
an insulated cooking chamber disposed within the cabinet, the airflow path being defined between the bottom panel and the insulated cooking chamber; and
a plurality of internal ridges disposed within the cabinet at the bottom panel below and outside of the insulated cooking chamber, each internal ridge of the plurality of internal ridges having a maximum-length edge extending along and parallel to the airflow path and defining a guided segment thereof, the plurality of internal ridges being spaced apart along the airflow path and thereby define a cross-path gap between adjacent ridges of the plurality of internal ridges permitting a portion of air in the airflow path from the high-flow center segment to the outer low-flow segment,
wherein the maximum-length edge is an edge wherein no other respective edge on each internal ridge exceeds its length.
