The user interface 14 of the third embodiment includes one touch slide element 16 and the display unit 20. Said touch slide ele- ment 16 is provided for adjusting the power level distribution on the cooking area 12 along the longitudinal direction. The display unit 20 represents the cooking area 10. The display unit 20 is provided for illustrating the power level distribution on the cooking area 12.
The touch slide element 16 includes the plurality of touch switch elements arranged in series along the longitudinal direction. Said touch switch elements are separately activatable and deactivatable by the user. In FIG 4 the display unit 20 illustrates three different power level distributions on the cooking area 12. In the first adjustment on the left hand side of FIG 4 the power level distribution includes five zones with the first power level 22, the second power level 24, the third power level 26, the fourth power level 28 and the fifth power level 30. The first power level 22 corresponds with the lowest power on the cooking area 12, while the fifth power level 30 corresponds with the highest power on the cooking area 12.
In the first adjustment on the left hand side of FIG 4 the five zones with the different power levels 22, 24, 26, 28 and 30 are arranged successively, wherein the power levels 22, 24, 26, 28 and 30 increases rearwards. A smaller rear portion of touch switch elements of the touch slide element 16 is activated, while a bigger front portion of touch switch elements of the touch slide element 16 is deactivated.
In the second adjustment in the centre of FIG 4 three zones with the different power levels 24, 26 and 28 are arranged successively, wherein the power levels increase rearwards . A bigger rear portion of touch switch elements of the touch slide element 16 is activated, while a smaller front portion of touch switch elements of the touch slide element 16 is deactivated.
In the third adjustment on the right hand side of FIG 4 three zones with the different power levels 26, 28 and 30 are arranged successively, wherein the power levels increase rearwards. All touch switch elements of the touch slide element 16 are activated . The present invention allows adjusting a one-dimensional power level distribution of the cooking area 12 by one touch slide element 16 as shown in FIG 3 and FIG 4. In particular, the present invention allows adjusting a two-dimensional power level distribution of the cooking area 12 by two touch slide elements 16 and 18 as shown in FIG 2. The user recognises the zones of the different power levels 22, 24, 26, 28 and 30 on the cooking area 12 by watching the display unit 20 and can place the one or more cooking vessels on the suitable zone or zones, respectively.
Although illustrative embodiments of the present invention have been described herein with reference to the accompanying drawings, it is to be understood that the present invention is not limited to those precise embodiments, and that various other changes and modifications may be affected therein by one skilled in the art without departing from the scope or spirit of the invention. All such changes and modifications are intended to be included within the scope of the invention as defined by the appended claims .
