Abstract
A warming device includes a corrugated tube, a storing portion, a heater, a temperature sensor, a drive control portion, and a determination processing portion. The corrugated tube includes a spiral portion. The storing portion stores the spiral portion and a liquid heating medium used for warming the spiral portion. The heater heats the storing portion. The temperature sensor is of a contact type, is provided at a position higher than the spiral portion, and is used for detecting a temperature of the heating medium. The drive control portion controls drive of the heater based on a detection temperature detected by the temperature sensor. The determination processing portion determines, based on the detection temperature obtained after a start of the drive of the heater, whether it is a shortage state where a storage amount of the heating medium in the storing portion falls below a predetermined lower limit amount.
