<p>An electric cooker comprises a fitting plate having an opening surrounded by an upwardly directed rim, a cooker plate received in the opening, the plate having a cooking surface on which a cooking vessel can be placed, and a sheet metal ring surrounding the cooker plate and projecting beyond the cooker plate. The sheet metal ring has an internal section which rests against the cooker plate and an external section which extends downwards at a particular low incidence and engages beyond the upwardly-directed rim of the fitting plate. The sheet metal ring is shaped and arranged on the electric cooker plate so that the transition from fitting plate to cooking surface allows cooking vessels to be pushed smoothly from the cooking surface on to the fitting plate, and vice versa. This is achieved by having a minimal elevation of the cooking surface over the fitting plate and/or by inter-adapted bevelling of the cooker plate, the sheet metal ring and the fitting plate. Capillary action tending to draw spilled liquids into the cooker is minimized by construction featuring sharp edges at all junction points.</p> |
