PROBLEM TO BE SOLVED: To favorably cool commodities stored in each commodity rack with the volume of air blown out of air outlets of each height level substantially maintained uniform.SOLUTION: A vending machine includes: a duct 20 which is disposed in a commodity storage box 11 and partitions a storage region 11a and a ventilation pass 11b; plural steps of commodity racks 12 disposed along a vertical direction in the storage region 11a; a blower fan F1 inside the storage box for circulating air outside and inside the storage region 11a by blowing out the air having passed through the ventilation pass 11b from an air outlet 22 of the duct 20 to the storage region 11a; and an evaporator 24 for adjusting the air circulated by the blower fan F1 inside the storage box to a desired temperature. The plural steps of the ducts 20 are disposed along the vertical direction in an upper region of the air inlet 21 and the cross-section area of the ventilation pass 11b becomes smaller as it advances upward. |
