Radiation heating unit for cooking utensils - has insulating support for resistors with transverse elevations in which resistors are partly embedded

摘要

The unit is esp. for vitrified ceramic electric cooking utensils with heating resistors mounted in a flat insulating support in the heating area, as in 27 29 929. It has shaped in it elevations in which the heating resistors are partly embedded, but apart from this they are not embedded and run on the insulating support surface. The insulating support surface is slightly wavy, with the crests (17) transversal to the resistors (18), forming the elevations (21) in which the resistors (18) are partly embedded.
