<P>PROBLEM TO BE SOLVED: To provide a storage capable of discharging a vaporized refrigerant to the outside of a storage chamber without deteriorating airtightness and heat insulation in the storage chamber. <P>SOLUTION: An ice-making chamber 20 is provided with an ice-making thermistor 30 detecting the leakage of the vaporized refrigerant from a cooler 28 into an ice storage chamber 12. A machine chamber 14 is defined below the ice storage chamber 12, and the machine chamber 14 is provided with a drain trap 50. An exhaust pipe 62 opened in the machine chamber 14 at its lower end is disposed at the lowermost section of a trap section 52 of the drain trap 50. The exhaust pipe 62 is provided with an opening/closing valve 64, a control device 29 opens the opening/closing valve 64 to discharge drainage in the trap section 52 to the machine chamber 14 when the ice-making thermistor 30 detects the leakage of the vaporized refrigerant, and the ice storage chamber 12 and the machine chamber 14 are made to communicate with each other via the exhaust pipe 62. <P>COPYRIGHT: (C)2012,JPO&INPIT |
