Hot water tank heating apparatus control device for automatic tea feeder

PURPOSE:To prevent the empty-heating of a hot water tank by preventing a heating apparatus from being activated when the level of the hot water in the hot water tank boiling the hot water to be poured on tea leaves with a built-in heating apparatus and storing it is lower than the lower limit position unable to activate the heating apparatus in an automatic tea feeder automatically making and feeding tea. CONSTITUTION:A hot water tank heating apparatus control device is constituted of a hot water guide pipe 29 communicated with a hot water tank 25 to guide the hot water in the hot water tank 25 to the outside of the hot water tank 25, connected with the left end to the bottom of the hot water tank 25, and located with the right end lower than the lower limit position 9B, a connecting pipe 32 connected with the lower end to the right end of the hot water guide pipe 29, located with the upper end above the lower limit position 9B, and made of an insulating material, a foil electrode 33 stuck on the outer periphery of the connecting pipe 32 and made of a metal foil, and a bar electrode 34 faced with the lower section to the foil electrode 33, dipped with the lower section in the hot water flowing into the connecting pipe 32 from the hot water tank 25 via the hot water guide pipe 29 when the water level in the hot water tank 25 is above the lower limit position 9B, and arranged in the connecting pipe 32.
