Patent number: 6870138Abstract: An electric cooking hob having a plurality of heating elements distributed in matrix formation below a heat-resistant surface on which one or more cooking utensils can be located in random manner. The cooking hob can determine the location, form and dimensions of one or more cooking utensils positioned on the cooking hob. The cooking hob uses a signal source to determine which heating elements lie under the cooking utensil. The cooking hob can heat the elements lying below the cooking utensil by a power source. Each heating element being able to be energized with a polarity opposite to the polarity of the current used to perform the determination, so that the power source and the signal source can be applied at the same time to different heating elements.Type: GrantFiled: January 15, 2004Date of Patent: March 22, 2005Assignee: Whirlpool CorporationInventor: Cristiano Pastore

Patent number: 6765179Abstract: An electric radiant heater (11, 111) is provided having an active sensor (21, 121) for detecting the position of a cooking vessel on a glass ceramic plate over the radiant heater (11, 111). The sensor (21, 121) is mad from electrically conductive material and is part of an inductive resonant circuit of a control operating by resonant circuit detuning. It also covers a heating zone (17, 117) of the radiant heater (11, 111). The sensor (21, 121) runs substantially linearly and, unlike conventional sensor coils, has a loopless construction. It is e.g. possible to stretch a wire (121) or also to use the tube (21) of a rod regulator.Type: GrantFiled: July 9, 2002Date of Patent: July 20, 2004Assignee: E.G.O.
