The invention refers to a baking oven comprising a baking chamber into which a carriage can be shifted which carries the baking good on support members, in particular baking plates, and which is stationary during the baking process, noting that air channels extend at both sides of the baking chamber over the height of the baking chamber from top to bottom, which air channels are separated from the baking chamber by partition walls having provided therein air flow openings formed by horizontal slots preferably extending over the whole depth of the support members as measured in shifting direction of the carriage, heated air being blown in alternating direction into the baking chamber by means of a blower.
Such baking ovens comprising a carriage being stationary during the baking process suffer frequently from the drawback, that the baking good distributed over the support members of the carriage is not uniformely baked. Experiments have shown that the reason for this has its origin in the fact that the heated air supplied via one of both air channels, although emerging with high speed from the air flow passages, becomes rapidly decelerated and thus arrives at the baking good with only reduced and moreover--as seen over the cross section of the baking chamber--with ununiform velocity.
