Operating unit to control a cooking hob

摘要

The unit (60) has a capacitive sensor (61) to select a cooking zone (20) by operating the capacitive sensor, and an adjusting element (65) to adjust a heating power of the selected cooking zone. A control unit records an operating duration of the capacitive sensor, selects a cooking zone in response to the operating duration being within in a time period, and activates or deactivates one of two heating rings (21, 22) of the selected cooking zone in response to the operation duration being within another time period, which does not overlap with the former time period.
