A DEVICE AND A METHOD FOR REDUCING THE TEMPERATURE OF A COOKING DEVICE

摘要

A temperature reducing device (10) for reducing the temperature of at least one hot plate (1) of a cooking device, wherein, when a signal from a sensor (2) indicates that no person is present in the vicinity of the cooking device and when the temperature of the hot plate exceeds a threshold temperature To, a control system (6) adjusts the hot plate to a temperature below the threshold temperature by adjusting the power supplied to the hot plate. The temperature reducing device is configured to determine pulse characteristics of a pulsed voltage supplied to said at least one hot plate and the control system is configured to determine whether the temperature of said at least one hot plate exceeds the threshold temperature based on said pulse characteristics.
