Abstract

PROBLEM TO BE SOLVED: To prevent a power waste that accompanys always preparing hot water of a high temperature by rapidly heating a prescribed amount of water while accompanying a control signal when a user approaches and supplying it to a prescribed part of a vending machine which needs hot water. SOLUTION: When a user approaches a vending machine and inputs coins, a controlling part outputs a control signal for supplying hot water in a hot water box 31 to a rapid heating box 34 and opens a 1st feed water valve 33. After a prescribed time (e.g. about 1 second) passes, the controlling part outputs a control signal that stoops the water supply, closes the valve 33 and also outputs a control signal for rapidly heating the hot water in the box 34 to a high temperature. High frequency power is generated from a heating heater driving part and applied to a rapid heating heater 35 by the control signal and the heater 35 rapidly heats the hot water in the box 34 up to a prescribed temperature. Furthermore, the controlling part opens a 2nd feed water valve 36 by the control signal and supplies the hot water in the box 34 to a beverage mixing part.
