PURPOSE:To reduce the dispersion of HOT sale temperature by detecting an input voltage to a high frequency power converter by an input voltage detector, correcting the time, which is accumulated in a timer, by a timer correcting means based on the result of the detection and correcting a heating time in correspondence to the input voltage. CONSTITUTION:A controller 7 is composed of a driving means 9 to receive a sale starting signal from a HOT sale switch group 8 and to drive a heating control means 5, timer 10 to accumulate the heating time and to output a heating ending signal to the driving means a at a stipulated time and timer correcting means 11 to correct the accumulated time of the timer 10 based on a detection signal from an input voltage detector 6. The input voltage to a high frequency power converter 3 is detected by the input voltage detector 6 and based on the result of the detection, the time accumulated in the timer 10 is corrected by the timer correcting means 11. Then, the heating control means 5 is driven by the driving means 9 according to a control signal from the timer 10 and the high frequency power converter 3 is controlled to a fixed output. Thus, the suitable HOT sale temperature can be always maintained for a canned drink. |
