PROBLEM TO BE SOLVED: To accurately detect a leaked refrigerant without increasing the manufacturing cost of an ice making machine. SOLUTION: A drain pan 54 which receives ice-making water discharged from an ice making mechanism 40 is disposed under the ice making mechanism 40 disposed in an ice making chamber 24. A refrigerant detecting sensor S capable of detecting a leaked refrigerant which is leaked from a refrigerating mechanism 30 disposed immediately above a drain port 60 formed in the drain pan 54. A machine chamber 22 and the ice making chamber 24 formed under the machine chamber 22 are made to spatially communicate with each other through a communication space formed at a left surface of a casing 12. By this, the leaked refrigerant which flows downward on the drain pan 54 and is collected in the drain port 60 and whose concentration has increased can be detected by the refrigerant detecting sensor S. The leaked refrigerant can be thereby accurately detected. COPYRIGHT: (C)2013,JPO&INPIT |
