Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a low cost power-saving vending machine which prevents fluid return to a compressor and efficiently operates a heat pump. SOLUTION: The vending machine includes a heating-cooling circulation circuit including a cooling circulation circuit comprising of a compressor 61, a condenser 62, a first tubule 63, a flow diverter 64, second tubules 72a, 72b, 72c, evaporators 65a, 65b, 65c, second return pipings 73a, 73b, 73c, and a first return piping 75, and a heating exchanger 66a placed in a product storage 40a. The vending machine performs efficient heat pump operations, preventing fluid return to the compressor 61 by thermally alienating the first tubule 63 and the first return piping 75 and thermally connecting the second tubules 72a, 72b, 72c and the second return piping 73a, 73b, 73c.
