ABSTRACT:
The heating unit is particularly adapted for a stove panel and the like, and comprises a pan adapted to be supported on the panel, the pan having an opening in its side wall. A sheathed electric heating element has an active heating portion formed into a flat spiral, such heating portion being supported crosswise of the top of the pan. The heating element has at least two terminal portions extending downwardly from the active heating portion and laterally thereof, the terminal portions extending through the pan opening for connection to a source of electrical energy. A closure, formed of an elastic material, such as cured silicone rubber, closes the pan opening. The terminal portions extend through the closure and the latter cooperates with the terminal portions to provide a hinge about which the heating element may be pivoted to swing the active heating portions upwardly from its supported position on the top of the pan.
