Abstract
A domestic oven includes a housing defining a cooking chamber, at least one stationary first heating element in the chamber, a shelf movably disposed in the chamber, a second heating element mounted to the shelf, and a drive operatively connected to the shelf for translating the shelf, together with the second heating element, in the housing. The shelf is made of heat conductive metal. A temperature sensor in heat conductive contact with the shelf senses the temperature of the shelf and of a metal tray or pan placed on the shelf in heat conductive contact therewith. The temperature sensor is operatively connected to an energization circuit for the second heating element for de-energizing the second heating element upon detecting a sudden rise in temperature. The second heating element is mounted to the shelf via insulating spacers. The oven is used to perform a hybrid steaming and baking method.
