Title:
HEATING DEVICE AND METHOD FOR DETECTING FAILURE OF HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/167473
Kind Code:
A1
Abstract:
A heating device (100) comprises: a heater (10) for heating an item (1) to be heated; a temperature detection unit (20) for detecting the temperature of the item (1); and a temperature adjustment unit (30) for controlling the heater (10) on the basis of a target temperature and the detected value of the temperature detection unit (20) so that the temperature of the item (1) reaches the target temperature. The heating device (100) determines, as a system gain change rate, the rate of change from the initial value of a system gain determined as a ratio of a temperature increase value of the item (1) with respect to electric power inputted to the heater (10), and determines the rate of change in the heat-retaining properties of the item (1) using the system gain change rate.
