- the passage opening 62 is open continuously in both heating operating states.
- the passage opening 62 is provided to allow pressure equalization between the cooking chamber 16 and the outside area. Furthermore, the passage opening 62 allows in the Closed state of the closure member 64 is an escape of the relation to the open state slowed down exhaust air stream 18th
- the exhaust air flow 18 has a flow velocity of at least 0.7 m / s, in particular at least 1.0 m / s and at most 1.6 m / s, in particular at most 1.2 m / s.
- the exhaust air flow 18 has a flow velocity of at least 0.2 m / s, in particular of at least 0.25 m / s and at most 0.4 m / s, in particular of at most 0.35 m / s ,
- the exhaust air entrained in the exhaust air flow 18 has a slower flow time in the closed state of the closure element 64, resulting in an increased contact time with the catalyst unit 30.
- a regulatory unit could have multiple ports.
- a passage opening could be designed to be closable.
