Abstract
PURPOSE:To reduce the energy consumption and to increase the quality of the stored goods, by consecutively detecting the temperature of goods in a direct or indirect way and at the same time detecting the temperature of the open air to carry out te control of temperature based on the outputs of those detections. CONSTITUTION:The voltage outputs of three temperature sensors in inside temperature sensors 13 and 14 that are provided with each independent block in a vending machine in addition to an open air temperature sensor 12 are supplied to a voltage comparator 16 to be compared with the output of a D/A converting circuit 15 that converts the digital signal supplied from a microcomputer 11 into an analog signal. The result of this comparison is read into the computer 11. Based on this result of comparison, the computer 11 drives relays XC, XH, XF1 and XF2 respectively to control the temperature of goods to a level matching the temperature of the open air.
