Abstract
A cooking appliance may include an oven cavity having a cavity top, a cavity back, and cavity side walls, an interior side wall extending parallel to each of the cavity side walls defining a passage therebetween, and a plurality of side rails extending along the interior side walls, the rails being rotatable between a rest position in which no oven rack is installed and airflow is blocked, and an active position in which the oven rack is installed and airflow is provided.
Claims16
A cooking appliance, comprising:
- an oven cavity having a cavity top, a cavity back, and cavity side walls,
- an interior side wall extending parallel to each of the cavity side walls defining a passage therebetween,
- a plurality of side rails extending along the interior side walls, the plurality of side rails being rotatable between a rest position in which no oven rack is installed and airflow to the oven cavity is blocked, and an active position in which the oven rack is installed and airflow to the oven cavity is provided,
- a lever is fixed to at least one of the plurality of side rails and configured to be actuated upon rotation of the at least one of the plurality of side rails, and
- an air grate associated with the at least one of the plurality of side rails and arranged within the passage between the interior side wall and at least one of the cavity side walls, wherein the air grate defines at least one grate opening, and configured to rest on the lever where the air grate is movable with the lever between a first position when the at least one of the plurality of side rails is in the rest position, and a second position when the at least one of the plurality of side rails is in the active position.

A convection oven having variable air flow patterns depending on oven rack placement therein, comprising:
- an oven cavity having a cavity top, a cavity back, and cavity side walls,
- a plurality of side rails extending along the cavity side walls, the plurality of side rails being movable between a rest position in which no oven rack is installed and airflow is blocked, and an active position in which the oven rack is installed and airflow is provided, wherein each of the cavity side walls define a set of air passages corresponding to each of the plurality of side rails and configured to provide convection air to the oven rack arranged on one of the plurality of side rails, and
- an air grate associated with at least one of the plurality of side rails and arranged within a passage defined within the cavity side walls, wherein the air grate defines a plurality of grate openings and is movable with the at least one of the plurality of side rails between a first position when the at least one of the plurality of side rails is in the rest position, and a second position when the at least one of the plurality of side rails is in the active position.
A cooking appliance, comprising:

- an interior side wall extending parallel to each of the cavity side walls defining a passage therebetween,
- a plurality of side rails extending along the interior side walls, the plurality of side rails being rotatable between a rest position in which no oven rack is installed and airflow is blocked, and an active position in which the oven rack is installed and airflow is provided,
- a lever is fixed to at least one of the plurality of side rails and configured to be actuated upon rotation of the at least one of the plurality of side rails, wherein the lever is in communication with an air grate and configured to vertically move the air grate upon actuation thereof, where the air grate is lowered in response to the at least one of the plurality of side rails being in the active position and elevated when the at least one of the plurality of side rails is in the rest position.
