Abstract (en)
Known electrically heated food supports have an essentially closed sheet metal body (1), in which at least one heating element is arranged. In order to insulate the heating element in relation to the sheet metal body (1), a large cavity is necessary in its interior. The new food support is to be more simple to manufacture and have lower heat losses. The sheet metal body (1) has at least two shaped sheets (2, 3) connected in regions to one another and the heating element contains a heating foil (8) with a heating resistance (9) embedded in an insulating material. <IMAGE>
Abstract (de)
Bekannte elektrisch beheizbare Backauflagen weisen einen im wesentlichen geschlossenen Blechkörper (1) auf, in dem mindestens ein Heizelement angeordnet ist. Um das Heizelement gegenüber dem Blechkörper (1) zu isolieren, ist in dessen Inneren ein größerer Hohlraum erforderlich. Die neue Backauflage soll einfacher herstellbar sein und geringere Wärmeverluste haben. Der Blechkörper (1) weist zumindest zwei bereichsweise miteinander verbundene Formbleche (2, 3) auf und das Heizelement enthält eine Heizfolie (8) mit einem in Isoliermaterial eingebetteten Heizwiderstand (9).
