Abstract
The invention relates to a method as well as a device to protect against overheating in a cooker extractor hood (1) over a cooker (7) with at least one fan device (4) and with at least one temperature sensor (5, 6). To this end the method includes the steps of detection of a temperature by the temperature sensor (5, 6); when a first temperature threshold is reached or exceeded (level 1) of increasing the blower output (4); when a second temperature threshold is reached or exceeded (level 2) of presentation of a second warning signal, and when a third threshold is reached or exceeded (level 3) of switching off the blower device (4).

18. A method for protecting a cooker extractor hood mounted above a cooker against overheating, with a blower device and a temperature sensor, the method comprising:
-
detecting a temperature with the temperature sensor; increasing the blower power when the temperature reaches or exceeds a first temperature threshold; displaying a warning signal when the temperature reaches or exceeds a second temperature threshold; and switching the blower device off when the temperature reaches or exceeds a third temperature threshold. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)

30. An overheating protection device, comprising:
-
a temperature sensor that provides a temperature signal; a blower controller responsive to the temperature signal reaching or exceeding a first temperature to increase a power to a blower device; a warning signal display that displays a warning when the temperature signal reaches or exceeds a second temperature threshold, wherein the blower controller is further responsive to switch the blower off when the temperature signal reaches or exceeds a third temperature threshold. - View Dependent Claims (31, 32, 33, 34, 35)
