PROBLEM TO BE SOLVED: To provide a vending machine capable of preventing the occurrence of heat loss caused by defrosting operation without needing a special device for treating drain water produced by defrosting. SOLUTION: A radiator and a first evaporator are arranged in a first merchandise chamber of the vending machine 3000. A No.1 second evaporator 7a is arranged in a second internal component storage chamber 410C of a second merchandise chamber 402C, and a No.2 second evaporator 7b is arranged near the upper end in a second circulating duct 420C. In the first merchandise chamber, a high-pressure high-temperature refrigerant is supplied to the radiator, and in the second merchandise chamber 402C, a low-pressure low-temperature refrigerant is supplied to the No.2 second evaporator 7b to perform the reverse operation of a blowing means 430C. At this time, internal air cooled by the No.2 second evaporator 7b flows out into a second merchandise rack 407C from the upper end of the second circulating duct 420C but does not cool merchandise S. The operation of an HH mode or an H mode can thereby be carried out. COPYRIGHT: (C)2008,JPO&INPIT
