Title:
INDUCTION HEATER FOR AUTOMATIC VENDING MACHINE
Document Type and Number:
Japanese Patent JPH01171093
Kind Code:
A
Abstract:
PURPOSE:To obtain a prescribed heating output without increasing a coil current by using a heating coil, which is successively wound on >=2 layers, at least, from an outer periphery. CONSTITUTION:The title heater is provided with a heating coil 10, which is successively wound on at least more than 2 layers from a center or the outer periphery in a circular arc shape so as to be along the cylinder shaped can wall of a canned drink 1, to execute the induction heating of the canned drink, a switching semiconductor and an inverter circuit 7 to be composed of a switching semiconductor 4, which is serially connected to the heating coil 10, and a resonating capacitor 3, which is connected in parallel with the heating coil 10 or the switching semiconductor 4, and to convert a direct current power to a high frequency power. Thus, even when the length of the heating coil 10 is around the length of the canned drink 1 and a turn number per layer goes to be reduced, the total turn number can be easily increased by obtaining the plural of >=2 layers. Then, the prescribed heating output can be obtained without increasing the coil current.
