VENDING MACHINE

PROBLEM TO BE SOLVED: To provide a vending machine that can reduce power consumption. SOLUTION: First and Second storages 11 and 12 configured for cooling and heating storages include heat pump circuits HP1 and HP2, respectively. A first valve device includes on-off valves V21 and V22 provided between a compressor 42 for heating and inner storage condensers 31 and 32. A second valve device includes check valves V31 and V32 provided between the inner storage condensers 31 and 32 and capillary tubes 71 and 72. This can avoid variation in the amount of a coolant circulated in the heat pump circuit for heating, thereby preventing efficiency of storage for heating from being reduced. This can also avoid flow of the high-temperature coolant out of the inner storage condenser under heating operation into the inner storage condenser of the storage under cooling operation, thereby preventing cooling efficiency of the storage for cooling from being reduced.
