A cooking enclosure is configured to hold food being cooked. The enclosure includes a surrounding, generally vertical, sidewall, projecting upward from a base. The base includes a floor bridging a bottom of enclosure, and the enclosure is capped by a vertically moving ceiling. The vertical moving ceiling secures a cooking heat source which is in thermal communication with the enclosure interior. The moving ceiling is configured to move up and down within the sidewall to vary, up and down, a volume of the cooking enclosure. The cooking enclosure is configured to have both a smaller cooking enclosure volume, suitable for quickly cooking small foods, and larger cooking enclosure volume necessary to cook larger foods.

The invention relates to a heater for generating an inhalable aerosol in an aerosol-generating device. The heater comprises at least two meshes. The meshes are arranged to be distanced from each other so that the meshes are configured for enabling wicking of aerosol-forming substrate between the meshes.

A heater system for an exhaust system is provided. The heater system includes a heater disposed in an exhaust conduit. The heater includes a plurality of heating elements disposed in the exhaust conduit. A heating control module controls the plurality of heating elements differently according to operating conditions specific to each heating element. In other forms, the heater system for an exhaust system has a plurality of heating zones, instead of a plurality of heating elements. The heating control module controls the plurality of heating zones differently according to operating conditions specific to each heating zone.

A heating device in the form of a radiant heating device for a hob has a sheet-like support with a support top side, with at least one heating element on the support top side, which heating element is highly corrugated and runs in tracks in a laying pattern. The heating element has at least two heating conductor strips which each have lateral sides and a top edge and a bottom edge. These at least two heating conductor strips are placed together or placed on one another by way of their mutually facing lateral sides and are at least partially in contact. The at least two heating conductor strips are connected to one another in a fixed and non-detachable manner, advantageously before corrugation.

The present invention relates to a heating module (14) with at least one PTC thermistor element (2) and at least one heating element (15), which is different from a PTC thermistor element (2), wherein the heating element (15) and the PTC thermistor element (2) are connected electrically in series. A simplified and cost-effective production and/or operation of the heating module (14) materialise in that the heating element (15) is thermally connected to the PTC thermistor element (2) in a heat-transferring manner and an electric current density through the PTC thermistor element (2) is lower than the electric current density through the heating element (15).

The invention, furthermore, relates to a heating device (31) having at least one such heating module (14).
