Abstract (en)
[origin: ES290831U] A cast material hotplate with heating resistors embedded in grooves on the bottom surface has an elongated oval shape and on the bottom surface two independent heating zones, which in each case contain substantially circular heating ring zones. In the intermediate area, the casting is separated by a separating gap and tightly interconnected by an inserted sheet metal strip, which is optionally provided with an expansion bead. The sheet metal strip ensures that the flat cooking surfaces are aligned with respect to one another and the double hotplate is suitable for individual cooking vessels, which can be placed on each of the two sides, and for large joint cooking vessels.
