1. A multi-cavity oven comprising:
a housing providing a cooking volume surrounded by insulated outer walls and at least one door that may open and close to provide access to the cooking volume;
a set of shelves dividing the cooking volume into cooking cavities, the shelves having air channels each leading from an air inlet to upwardly or downwardly directed airstream openings and into adjacent cavities;
at least one fan providing air through the air channels into the air inlets;
a water inlet communicating with a water valve to introduce water into the cooking cavities; and
a controller communicating with the fan and the water valve to provide a first and second cleaning state wherein in the first state, the fan operates below a predetermined airflow rate to allow water from the water inlet to drain backward into and accumulate in the air channels and in a second state the fan operates above the predetermined airflow volume to rapidly expel accumulated water from the air channel through the airstream openings in at least one stream.
