AUTOMATIC VENDING MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an environmental-friendly automatic vending machine for reducing electric power consumption, by using cold heat and hot heat generated by a Stirling refrigerator. SOLUTION: The automatic vending machine has: the Stirling refrigerator 51; an evaporator 62 radiating the cold heat generated by the Stirling refrigerator 51; a radiator 72a exhausting the hot heat generated by the Stirling refrigerator 51; a heater 72b radiating the hot heat generated by the Stirling refrigerator 51; a heat exchange chamber 81c arranged in a lower part of a storage inside storage of the automatic vending machine; and a storage inside air blowing fan 83c. The evaporator 62 and the heater 72b are arranged in the heat exchange chamber 81c. The electric power consumption of the automatic vending machine is reduced, by using the hot heat generated by the Stirling refrigerator 51 for heating the storage inside storage of the automatic vending machine, by switching its cold heat or the hot heat by a cooling-heating switching means 82c.
