Abstract

A warming device includes a corrugated tube, a storing portion, a heater, a water level sensor, and a determination processing portion. The corrugated tube includes a spiral portion that is formed spirally. 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 water level sensor detects a water level of the heating medium in the storing portion. The determination processing portion determines, based on a detection water level detected by the water level sensor, whether or not the heating medium is in a heating medium shortage state where a storage amount of the heating medium in the storing portion falls below a predetermined lower limit amount.
