发明名称 Corrugated electric heating element and related radiant hotplate
摘要 An electric radiant hotplate includes a base of electrically insulating material and a peripheral crown extending along the outer rim of the base and projecting upwards. A strip of resistive material is inserted in the base and is formed by a sequence of planar lengths and curved lengths connected to respective planar appendices that are inserted in the insulating base. The appendices can be connected to the planar lengths by respective peduncles applied on to the same side edge of the flat strip of resistive material. The appendices can also be either coplanar or not coplanar to the planar lengths and include a first portion connected to the respective planar length of the strip, and at least a second planar portion that is not coplanar with the first portion and is joined to the first portion via a rectilinear border, the first portions being applied on a same side edge of the flat strip of resistive material.
