Electric hotplate with a mounting ring around it

Abstract From the Canadian patent

Hotplate is fitted by means of a relatively wide and shallow mounting ring, whose outer edge rests on a mounting plate made from glass ceramic or other materials. At edge it is adhered to mounting plate using a thermally stable adhesive, which simultaneously forms the seal agains cooked articles running through. The sheet metal insert ring covers the inner circumference of mounting opening in the mounting plate and has an upper outwardly directed flange engaging over the seal. Simultaneously the seal in conjunction with the, insert ring, centres the hotplate in the mounting opening. According to a variant a release ring can be inserted for releasing the hotplate.
