Abstract

A method for operating a stove including providing a plurality of burners beneath a cooktop surface and a plurality of visible-light emitters mounted under the surface for separately, variably illuminating edges of the surface adjacent to each of the burners, providing a touch-and-proximity sensor for detecting objects above the surface, illuminating at least one edge of the surface in response to the sensor detecting a pot suspended above one of the burners, and intensifying the illuminating commensurate with proximity of the pot to the one burner, as further detected by the sensor.

Claims

1. A method for operating a stove comprising (i) a controller, (ii) a cooking surface comprising illuminable segments on outer edges of the surface, the illumination of the segments being controlled by the controller, (ii) a plurality of burners under the surface, controlled by the controller, each burner located adjacent to one or more illuminable segments associated therewith, and (iv) one or more touch-and-proximity sensors near the burners and connected to the controller, the method comprising:

in response to the sensors detecting a pot placed above one of the burners, illuminating, by the controller, the one or more illuminable segments associated with that burner; and

in response to the sensors detecting an object gliding along an illuminated segment;

adjusting, by the controller, the temperature of the burner associated with that illuminated segment; and

correspondingly changing, by the controller, the illumination of the one or more illuminated segments associated with that burner.

2. The method of claim 1, wherein said correspondingly changing the illumination of the one or more illuminated segments associated with a burner is commensurate with the amount of adjustment of that burner'"'"'s temperature.

3. The method of claim 1 wherein said adjusting adjusts the temperature of the burner by an amount corresponding to the extent that the object glides along the illuminated segment.

4. The method of claim 1 further comprising, in response to the sensors detecting a person approaching the surface:

entering, by the controller, a burner selection mode that enables selecting one of the burners; and

illuminating, by the controller, at least one of the illuminable segments.

5. The method of claim 1 further comprising, in response to the sensors detecting a pot placed above one of the burners, entering, by the controller, a temperature selection mode that enables adjusting a temperature for a selected burner.

6. The method of claim 1 wherein the stove further comprises a plurality of visible-light emitters under the surface, controlled by the controller, independently illuminating the illuminable segments, and wherein said illuminating and said changing the illumination is performed by the controller vis-à

-vis the emitters.

7. A stove comprising:

a controller;

a cooktop surface comprising illuminable segments on outer edges of the surface, the illumination of the segments being controlled by the controller;

a plurality of burners under said surface, controlled by said controller, each burner located adjacent to one or more illuminable segments associated therewith;

first and second sensors, near said burners and connected to said controller, the first sensor comprising a proximity sensor operative to detect objects on said surface, and the second sensor comprising a touch sensor operative to detect an object gliding along one of said illuminable segments,

wherein said controller is operative to;

(i) in response to said first sensor detecting a pot above a burner, illuminate the one or more illuminable segments associated with that burner, and

(ii) in response to said second sensor detecting an object gliding along an illuminated segment, adjust the temperature of the burner associated with that illuminated segment, and correspondingly change the illumination of the one or more illuminated segments associated with that burner.

8. The stove of claim 7, wherein said controller is operative, in response to said first sensor detecting the pot being lowered onto a burner, to illuminate the one or more illuminable segments associated with that burner.

9. The stove of claim 7, wherein said first and second sensors are light-based sensors.

10. The stove of claim 7 further comprising a third sensor connected to said controller, the third sensor comprising a proximity sensor operative to detect a person approaching the surface, wherein said controller is further operative to, in response to said third sensor detecting the person approaching the surface, enter a wakeup mode that enables selecting one of said burners.

11. The stove of claim 7 wherein said controller is further operative to, in response to said first sensor detecting a pot above a burner, enter a temperature selection mode that enables adjusting a temperature of a selected burner.

12. The stove of claim 7 further comprising a plurality of visible-light emitters under the surface, controlled by said controller, independently illuminating the illuminable segments, and wherein said controller illuminates the one or more illuminable segments associated with a burner, and changes the illumination of one or more illuminated segments associated with a burner, vis-à

-vis said emitters.
