A heating unit for use in a cooktop is disclosed. The heating unit includes a pan with an insulation structure supporting a heating element. The heating unit further includes a temperature sensor and indicator to be used as a visual indication to the user that the heating unit is energized.

Temperature sensor for heater unit in cooktop range

The present invention provides a radiant heating unit for a cooktop. The heating unit includes a cooking plate, a support pan, an insulation layer, a heating element, a temperature sensor, and a support post. The support pan is disposed beneath the cooking plate. The insulation layer is supported in the pan and includes an insulation base and an insulation sidewall ring. The heating element is supported on the insulation base in a spaced apart relationship to the cooking plate. The heating element is capable of radiating direct radiant energy. The temperature sensor senses the temperature inside the heating unit and includes a sensing element and lead wires. The support post has an upper head portion and a lower base portion. The upper head portion has a recess to house at least a portion of the sensing element of the temperature sensor. The recess also shields at least a portion of the sensing element from direct radiant energy of the heating element.

Modular heating unit for cooktops

A modular radiant heating unit adapted for installation into a cooktop or the like. In one embodiment, the heating unit comprises an open-topped pan having a bottom and circumferential sidewall defining a flanged upper rim. A thermally insulating support element disposed in the bottom of the pan, and a radiant heating element is disposed in a pattern on the support element. An insulation ring is extends around and adjacent to the inner surface of the circumferential sidewall of the pan. A thermally insulating washer-like gasket is disposed atop the insulation ring and the flanged upper rim of the pan. A glass-ceramic cover plate is disposed atop the gasket, such that the gasket enhances the seal between the plate and the pan. The present invention also includes methods of assembling a modular radiant heating unit having such a gasket.
