Title:
HEATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/138830
Kind Code:
A1
Abstract:
This heating device (100) includes: a heater (10) for heating an object (1) to be heated; a temperature detection unit (20) for detecting a temperature of the object (1) to be heated; and a temperature regulator (30) which, on the basis of a detection value of the temperature detection unit (20) and a target temperature, controls the heater (10) so as to make the temperature of the object (1) to be heated equal to the target temperature. The temperature detection unit (20) comprises a plurality of temperature sensors (21, 22). An identification unit (34) identifies, from temperature data detected by the temperature sensors (21, 22) and manipulation quantity data corresponding to electric power applied to the heater (10), a heat transfer function between the heater (10) and the temperature sensors (21, 22), and a heat transfer function between the respective temperature sensors (21, 22). A determination unit (36) detects a change from initial values of coefficients of the transfer functions, and, on the basis of that change, determines an abnormality in the heater (10) or the temperature sensors (21, 22).
