Abstract: A refrigerator includes a cabinet and a shelf. The cabinet has a rear wall and opposing side walls extending forward from the rear wall. The rear wall and opposing side walls define an internal cavity. The shelf is disposed within the internal cavity, has a base portion defining a plurality of aligned grooves, and has an extendable portion having a plurality of aligned protrusions. Each protrusion is disposed and slidable within one of the aligned grooves. The extendable portion is configured to transition between first and second positions relative to the base portion via sliding the plurality of aligned protrusions within the plurality of aligned grooves.

Abstract: A ventilation system for an oven is provided. The system includes a rear duct assembly. The rear duct assembly includes vertical walls defining a vertical air flow path along a rear of the oven, and a separator plate dividing the vertical air flow path into a first air flow configured to receive air from oven electronics and a second air flow configured to receive air from an oven cavity. The separator plate extends vertically downward between the vertical walls from the top of the vertical air flow path a portion of the height of the oven until a mixing zone at the rear of the oven into which the first and second air flows combine into a combined air flow.
