Abstract
In a cooking unit (1) in the marginal region of the underside of hotplate (3) a tensile stressed support (4) is fixed immediately adjacent to the outer circumference (8) of a radiant heater (2). Support (4) engages below a cover (13) of the insulation of radiant heater (2) serving as a base plate and at least one spring (22) is arranged between a marginal strip (16) and the underengaging leg (19), so that a prestressed, closed assembly for fitting in a hob or the like is formed. Appropriately there are several closely juxtaposed, rectangular radiant heaters (4) with in each case separately switchable or regulatable heating circuits, so that at least approximately 85% of the total surface of the cooking field can be directly heated.
