<P>PROBLEM TO BE SOLVED: To enhance the safety of automatic dispenser using a combustible refrigerant by reliably discharging the refrigerant leaked in a storage. <P>SOLUTION: The automatic dispenser is provided with an outside air introduction means 29 constituted of a suction fan 26 and a ventilation flap 28 in an upper portion of an inner door, and a flange 34 is formed around a fan mounting bracket 27. When leakage detection means 22 detects leakage, the suction fan 26 is driven to introduce fresh air and the refrigerant accumulated in the storage is discharged through an commodity delivery port and a drain water discharge port; thereby the refrigerant density in the storage can be reduced swiftly and safely at low cost without using any particular sealing member. <P>COPYRIGHT: (C)2012,JPO&INPIT |
