Abstract

The invention refers to a baking oven having a baking chamber which is accessible via a door and which is designed for introducing therein a carriage carrying baking goods so that the carriage is stationary during a baking process. The baking oven comprises two air channels extending laterally of the baking chamber at both sides thereof over the effective height of the baking chamber and being each separated from the baking chamber by a partition provided with a plurality of air passage openings. The air channels are, during the baking process, alternately supplied by a blower and, via a switching equipment, with hot air heated by a heating means. The hot air is humidified by a vapor supply means and transversely passes the baking chamber in alternating directions and is subsequently again sucked back along a closed circuit to the suction side of the blower. The blower and heating means are arranged at a higher level than the baking chamber and at least partially above said baking chamber.
