    If desired, the steam generator 105 may include a support device removable from the steam production chamber 120, so that the steam production chamber 120 rests on said support device and that said support device has at least a portion of the bearing surface intended to rest on a container. The support device may in particular have an annular configuration or a U-shaped configuration. Alternatively, the removable support device may in particular belong to the cover 103.
    Alternatively, the vapor detector 29; 129 is not necessarily formed by a temperature sensor such as for example a NTC resistor or a thermostatic switch, but can be of any type, in particular a flow sensor or a humidity sensor. The heating power of the heating device 50; 150, can be regulated by electronic means. The variation of the heating power of the heating device 50; 150 can be obtained by alternating periods of full power heating and periods of shutdown. However, a simple switching between an initial power and a reduced power may suffice.
    In the exemplary embodiments illustrated, the vapor detector 29; 129 extends inside the vent 18; 118. As a variant, the vapor detector 29; 129 could form a wall portion of the vent 18; 118, in particular when the detector is formed by a thermostatic switch.
    In the exemplary embodiments illustrated, the vent (18; 118) forms a straight ascending duct. Alternatively, the vent could form a conduit having at least one baffle.
    The present invention is not limited to the embodiments described and their variants, but encompasses numerous modifications within the scope of the claims.
