CORRUGATED ELECTRIC HEATING ELEMENT AND RELATED RADIANTG HOTPLATE

摘要

Electric radiant hotplate, suitable also for use in cooking tops, comprising: a base of electrically insulating material, a pe ripheral crown extending along the outer rim of said base and projecting upwards, at least a strip or resistive material that is inserted in said base dand is formed by a sequence of planar lengths and curved lengths are connected to respective planar appendices that are inserted in the insulating base. In one embodiment, said appendices are connected to the planar lengths by means of respective peduncles applied on to the same side edge of the flat strip of resistive material. In other embodiments, said appendices are either coplanar or not coplanar to said planar lengths, and comprise: a first portion connected to the respective planar length of the strip, at least a second planar portion that is not coplanar with the first portion and is joined to the latter via a rectilinear border, in which said first portions are applied on a same side edge of the flat strip of resistive material.
