BAKING OVEN WITH A VAPOUR CHANNEL IN WHICH A CATALYST AND A GAS SENSOR ARE ARRANGED

摘要

A baking oven is disclosed having a vapour channel (2) in which a catalyst (4) is arranged in such a way that the vapours generated in the baking oven and carried away through the vapour channel (2) must flow through the catalyst (4), and in which a moisture sensor (8) connected to a control (6) of the baking oven in a signal-transmitting manner is arranged downstream of the catalyst (4). In order to provide a baking oven in which a semiconductor gas sensor can be used as moisture sensor (8) in order to control or regulate the baking oven, and achieve at the same time high control or regulation accuracy, the semiconductor gas sensor (8) is arranged in such a way that the vapours conducted through the vapour channel (2) and coming into contact with the semiconductor gas sensor (8) necessarily flow through a catalyst (4; 26) for oxidising the oxidisable gases contained in the vapours before they reach the semiconductor gas sensor (8).
