ABSTRACT:
A raised-level cooking appliance has a heating chamber with a lowerable trapdoor and a drive device. The drive device is configured to lower and lift the trapdoor. The drive mechanism is subject to a tension force, counteracting a weight of the trapdoor. The drive for moving the trapdoor may be switched off when the trapdoor comes into contact with an upper or lower stop in a simpler and more reliable manner. A control device controls the drive device in dependence on a magnitude of the tension force acting on the drive mechanism.
