Definitions

  • the invention relates to a cooking hob, wherein the hob has a plurality of heating elements and wherein the heating elements have a rectangular shape.
  • Hobs of this kind are known for example from EP 0 921 711 A1 .
  • an induction oven which has a hob which is divided into separate,hob parts. All hob parts are equipped with rectangular induction coils. To reduce the space required for cooking using a certain number of cooking pots the disclosed induction oven supplies each hob part with two induction coils which are controlled together, i. e. dependently from each another.
  • each heating element is controlled separately by a controlling device and groups of at least two adjacent heating elements can be switched together and/or activated by the controlling device.
  • a detection device e.g. an inductive or capacitive detection device, is provided to detect on which of the heating elements the pot or cooking utensil is standing or is closest to and these heating elements are grouped together as a cooking zone or activated to heat the pot.
  • the heating elements are induction heating elements or coils. I this case the heating elements themselves can be part of an inductive detection device for detecting the presence and size of a cooking utensil or pot.
  • the heating elements are resistance heating elements.
  • the hob is preferably divided into at least two rows of hob parts which are arranged along a direction from the front side to the rear side of the hob, wherein each hob part has one heating element. Also it is beneficial that the hob is divided into at least four columns of hob parts which are arranged along a direction transversely to the direction from the front side to the rear side of the hob, wherein each hob part has one heating element.
  • the extension of the hob parts in the direction from the front side to the rear side is advantageously between 200 mm and 250 mm.
  • the extension of the hob parts in the direction transversely to the direction from the front side to the rear side is preferably between 130 mm and 160 mm.
  • the extensions of all hob parts are equal in the direction from the front side to the rear side; also the extensions can be equal in the direction transversely to the direction from the front side to the rear side.
  • four or five hob parts are arranged along the direction transversely to the direction from the front side to the rear side and two hob parts are arranged along the direction from the front side to the rear side.
  • each heating element is switchable on and off by a separate switch which is part of the controlling device.
  • a preferred embodiment comes up with each heating element being adjustable in its energy consumption by a separate switch which is part of the controlling device.
  • Fig. 1 shows a domestic oven 1.
  • a cooking hob 2 is located on the upper surface of the oven 1 .
  • the hob is supplied with a plurality of heating elements 3.
  • a selection of heating elements are numbered with 3', 3", 3"' and 3"".
  • Each heating element 3 has a rectangular shape in the top view.
  • each heating element 3 forms with regard to its extensions a respective part of the hob 2, i. e. a hob part.
  • each heating element 3, 3', 3", 3"', 3"" is controlled separately by a controlling device 4, 4'; 4", 4"', 4"".
  • the switching on and off as well as the adjustment of the heating power is done by a number of switches 7, which are arranged in the front side 5 of the oven 1.
  • Each individual switch 7', 7", 7"', 7"" is connected to a separate controlling device 4, 4', 4", 4"', 4"" as illustrated in fig. 2 .
  • a big pot 8 is arranged on two of the hob parts or heating elements 3', 3" respectively. So, by activating the heating elements 3' and 3" the big pot 8 can be heated up'.
  • the hob part or heating element in the left upper corner is used when a small pot 9 is to be heated up.
  • the middle hob part or heating element in the upper row of heating elements is used when a pan 10 is to be heated up.
  • the four heating elements in the upper and lower row which are located on the right side of the hob 2, are used to heat up a roasting tray 11.
  • the energy of four heating elements is employed.
  • the pot/dish/tray can be placed so that one heating element is covered - specifically the centre of it - and the boarder line between the different heating elements is not passed.
  • An alternative positioning is to place the pot/dish/tray so that more than one heating element is covered.
  • the common boarder line of two or more adjacent heating elements is not passed.
  • a preferred embodiment of the invention has a width of the oven 1 (in direction B) of about 80 cm.
  • the effective width of the hob 2 (in direction B) is e. g. 715 mm.
  • a single hob part or heating element 3 has a width of 143 mm.
  • the extension of the heating element or hob part in the direction T can be 227.5 mm, so that the total extension is 455 mm.
  • the cooking hob 2 can also be a built-in cooking hob instead of being part of an oven 1.
